As mobile phone users, all we want is enough battery life to last the day. Frustratingly, the older the device, the less power it seems to have.

In fact, the amount of battery life our mobiles have on any given day depends on two key factors: how we use them on that particular day, and how we used them in the past.

Mobile phones use lithium-ion batteries for energy storage. In this type of battery, lithium metal and lithium ions move in and out of individual electrodes, causing them to physically expand and contract.

Unfortunately, these processes are not completely reversible and the batteries lose their charge capacity and voltage as the number of charge and discharge cycles grows.

To make matters worse, the electrolyte (electrically conductive liquid) that connects the electrodes also degrades throughout these cycles.

The ability of lithium-ion batteries to store charge depends on the extent of their degradation. This means there is a link between how we handle our devices today and the charge capacity available in the future.

Through a few simple steps, users can minimise this degradation and extend their device’s life.

Strategies for extending battery capacity

Control battery discharge

Typical lithium-ion batteries for mobile phones are supposed to retain 80% of their charge capacity after 300-500 charge/discharge cycles. However, batteries rarely produce this level of performance, with charge storage capacity sometimes reduced to 80% levels within only 100 cycles.

Fortunately, we can extend our future battery capacity by limiting how much we discharge our mobile phone batteries. With most battery degradation occurring during deep discharge/charge cycles, it is actually better to limit the battery discharge during any one cycle before charging it again.

As it happens, our devices do have battery-management systems, which reduce damage from overcharging and shut down automatically if the battery gets too low.

Nonetheless, to maximise the battery capacity in the future we should avoid that 0% battery mark altogether, while also keeping those batteries at least partially charged if storing them for a prolonged period of time to avoid deep discharge.

Extend charging times

Many of today’s mobile devices have a fast charge option that enables users to supercharge them in minutes rather than hours. This is convenient when we’re in a rush, but should be avoided otherwise.

Why? Because charging a battery too quickly reduces its storage capacity.

Physically, the shuttling of lithium metal and lithium ions between the electrodes in lithium-ion batteries is a slow process. Therefore, charging at lower rates allows more complete shuttling to occur, which enhances the battery’s charge capacity.

For example, charging a phone in five minutes compared with the standard two hours can reduce the battery capacity for that charge cycle by more than 20%.

Keep the temperature just right

Fortunately, for most parts of the country, temperatures in Australia sit between 0℃ and 45℃ throughout the year. This is the exact range in which lithium-ion batteries can be stored to maintain optimal long-term charge capacity.

Below 0℃, the amount of power available within the battery system is reduced because of a restriction in the movement of lithium metal and lithium ions within the electrodes and through the electrolyte.

Above 45℃, the amount of power available is actually enhanced compared with lower temperatures, so you can get a little more “juice” from your battery under hotter conditions. However, at these temperatures the degradation of the battery is also greatly accelerated, so over an extended period of time its ability to store charge will be reduced.

As a result, phones should be kept out of direct sunlight for prolonged periods, especially in summer when surface temperatures can increase to above 70℃.

Mobile phones only have a limited number of charge cycles before the battery loses its capacity to recharge entirely.

Use battery-saving modes

Aaron Carroll and Gernot Heiser from Data61 analysed the power consumption of different smartphone components under a range of typical scenarios.

They concluded there are a handful of simple software and hardware strategies that can be used to preserve battery life.

  • Reduce screen brightness. The easiest way to conserve battery life while maintaining full function is to reduce the brightness of the screen. For devices such as mobile phones that have an organic light emitting diode (OLED) display, you can also use the “light on dark” option for viewing.

  • Turn off the cellular network or limit talk time. The connection to the cellular network uses the global system for mobile communication (GSM) module. The GSM is the most dominant energy-consuming component in a mobile phone, so it is beneficial to turn it off altogether or at least limit call time.

  • Use Wi-Fi, not 4G. With Wi-Fi being up to 40% less power-hungry than 4G for internet browsing, turning off cellular data and using Wi-Fi instead will help your battery life.

  • Limit video content. Video processing is one of the most power-consuming operations on a mobile device.

  • Turn on smart battery modes. All modern mobile devices have a smart battery saving mode (for instance, Android has Power Saving Mode and iOS has Low Power Mode). These software features modify central processing unit (CPU) usage for different apps, screen brightness, notifications and various hardware options to reduce energy consumption.

  • Use Airplane mode. This mode typically disables GSM, Wi-Fi, bluetooth and GPS functions on your devices. When turning off all such auxiliary functions, the device will use only up to 5% of its usual energy consumption with the screen off. For comparison, simply having your device in idle can still use more than 15%.

Enhancing your phone’s battery usability requires a combination of limiting the use of power-hungry hardware and software, as well as handling mobile devices so as to maximise the charge capacity and minimise battery degradation.

The ConversationBy adopting these simple strategies, users can extend their battery life by more than 40% in any given day while maintaining a more consistent battery capacity throughout the lifetime of the device.

Pakistani Officials Back Muslim Land-Grabbers, Christians Say


Senior district authorities accused of supporting desecration of 150 Christian graves.

LAHORE, Pakistan, March 9 (CDN) — Christians in south Punjab Province are accusing senior district officials of supporting local Muslims who allegedly demolished 150 Christian graves and desecrated holy relics – and are now threatening Christians seeking legal redress.

In the Kot Addu area of Muzaffargarh district, Waseem Shakir told Compass by telephone that an influential Muslim group last Nov. 6 took illegal possession of a 1,210-square yard piece of land designated as a Christian cemetery and set up shops on it. Official records state that the portion of land was allotted as a Christian cemetery, he said.

“Local Muslims demolished 150 Christians’ graves and desecrated the cross and biblical inscriptions on the graves in a bid to construct shops on the property,” said Shakir, a resident of Chak (Village) 518, Peer Jaggi Morr, Kot Addu. “Only five marlas [151.25 square yards] are all that is left for the Christians to bury their dead now.”

Shakir said that all Muzaffargarh area authorities, including the local politicians, were supporting the alleged land-grabbers even as Christians feared a mob attack.

“The situation has come to point where even the local police have warned their higher-ups that the tension could provoke a Gojra-type incident,” he said, adding that Muslim instigators were now openly trying to intimidate him and Boota Masih, who registered a case with police, into dropping the matter.

In Gojra on Aug. 1, 2009, Muslim hordes acting on an unsubstantiated rumor of blasphemy of the Quran – and whipped into a frenzy by local imams and banned terrorist groups – killed at least seven Christians, looted more than 100 houses and set fire to 50 of them. At least 19 people were injured in the melee.

Shakir said Christians had approached police and the district administration to register a case against the Muslims for desecrating their sacred relics and hurting religious sentiments, but authorities have shown little attention to their grievance. Masih registered the complaint on behalf of area Christians, but the station house officer of the Daira Deen Panah Police, Waseem Leghari, altered it to state that Muslims had only occupied a piece of the cemetery land, Shakir said.

“Leghari registered a case against the Muslims under Section 297 of the Pakistan Penal Code [trespass of a place for the dead], which is a bailable offense, despite the fact that a case under the blasphemy law should have been registered against the Muslims for desecrating the Christian holy relics,” Shakir said.

Police took no measures to arrest the 11 named suspects, he added.

“No one seems bothered over the desecration of our cross and biblical inscriptions,” Shakir said.

Section 297 of the penal code states, “Whoever, with the intention of wounding the feelings of any person, or of insulting the religion of any person, or with the knowledge that the feelings of any person are likely to be wounded, or that the religion of any person is likely to be insulted thereby, commits any trespass in any place of worship or on any place of sculpture, or any place set apart for the performance of funeral rites or as a depository for the remains of the dead, or offers any indignity to any human corpse or causes disturbance to any persons assembled for the performance of funeral ceremonies, shall be punished with imprisonment of either description for a term which may extend to one year, or with fine, or with both.”

Shakir said that, besides the 150 demolished graves, the illegal occupants had thrown garbage on another 50 graves. The police’s indifferent attitude towards the Christian community had been hurtful, he said, and Christians had repeatedly taken up the issue with District Police Officer (DPO) Chaudhry Manzoor and District Coordination Officer Tahir Khurshid.

They did not take the issue seriously, Shakir said.

DPO Manzoor rejected the Christians’ accusations.

“It’s not as serious a case as they are portraying,” he told Compass. “The people who have built shops on the land are not illegal occupants but the real owners.”

He said Christians were furious because the shopkeepers put some of their belongings on the graves.

“No one has desecrated any Christian holy symbol, book or grave,” he said. “Any fears that the issue could lead to another Gojra are baseless.”

Manzoor said the matter would be resolved amicably.

Napolean Qayyum, leader of the Minorities Wing of the ruling Pakistan People’s Party (PPP), told Compass that open desecration of the Christian symbols and places and the police’s alleged support of the culprits showed the prejudice of the Punjab government towards minority groups.

“An application regarding this incident is lying in the Punjab chief minister’s secretariat, but it seems the Pakistan Muslim League-Nawaz’s [PML-N] government in Punjab wants another Gojra-like incident to take place in Kot Addu,” he said, adding that it was curious that all major violence against Christians usually takes place when the PML-N is in power in the province.

Qayyum said that he had taken up the matter with the PPP leadership.

“It’s a case of blasphemy, and the culprits should have been rounded up under Section 295-A,” he said. “I have contacted Farahnaz Ispahani, the political adviser to President Asif Zardari, and she has assured me of the federal government’s support in this matter.”

He added that stern action against local police and administrative authorities was necessary to set an example for others.

SUDAN: SUPPORT FOR PRESIDENT LEADS TO ATTACKS ON CHURCHES


Militia destroys church building in the Nuba Mountains

NAIROBI, Kenya, April 8 (Compass Direct News) — Support for Sudanese President Omar Hassan al-Bashir in the wake of an International Criminal Court (ICC) warrant is fast turning into orchestrated attacks on Christians.

A thatched-grass building in the Nuba Mountains village of Chat, used by the Evangelical Presbyterian Church and the Sudanese Church of Christ, is one of the latest targets of such attacks.

The building was destroyed by fire on March 27 by a suspected government militia. Pro-Bashir mobs have attacked those they believe support the ICC’s determination to prosecute Bashir for atrocities in the Darfur region.

As support for President Bashir escalates, especially in the North, the church faces one of the worst threats to its existence in the recent past. Today, it struggles simply to survive.

Drivers on the streets of Khartoum, even the road leading toward the airport, see huge pictures of Bashir staring down from billboards with pro-Bashir messages, such as “Mr. President, we are with you” and “You are not alone.”

Kuwa Shamal, acting director of the Sudanese Church of Christ, says of the billboard campaign: “I wish the same government assuring support to the president could have the same encouraging message for the struggling church.”

 

Chief Accused of Leading Attack

The Sudanese Church of Christ was forced to conclude a morning worship service prematurely on March 27 when a hostile group attacked. An eyewitness said this militia was led by the area chief, Kafi Tahir, who supports an Islamist agenda and is said to receive government support.

The eyewitness, a Muslim who requested anonymity, said the chief and his accomplices were armed. Helpless church members fled the structure, which had a capacity of about 500. The chief then ordered his accomplices to set the church ablaze and church members ran for their lives, the eyewitness said.

“The Sudanese Church of Christ is concerned of the government move to frustrate the activities of the churches in Nuba Mountains,” said Barnabas Maitias, president of the Sudanese Church of Christ. “It is alleged that the Ministry of Defense has distributed a number of weapons to individuals who are out to support Islamic agenda and the government in Nuba Mountains, including Chief Kafi Tahir of Chat village, who recently led a group of unknown people to destroy our church.”

Indeed, many Christians are worried as a new wave of intolerance sweeps the region. The intolerance could worsen as ICC prosecutor Luis Moreno-Ocampo continues to press for a court trial of Bashir.

Matta Mubarak, general secretary of the Sudanese Church of Christ, told Compass that the villagers of Chat have previously opposed the chief, who then destroyed the church building in retaliation.

“The chief fled for his life to Kadugli and he is living a comfortable life. As a result, justice for the church in Nuba Mountains has been thrown out of the window,” Mubarak said. “What kind of a world are we living in, where criminals are not charged? The church feels that the Sudanese government is not concerned about the rights of Christians in the North. The future of the church in the North is uncertain.”

 

Worshiping Without Buildings or Land

For a month now, members of the Evangelical Presbyterian Church have worshiped outdoors and without the help of an evangelist who had led them.

Shamal said that evangelist Aburahaman Tai of the Evangelical Presbyterian Church was attacked in early March outside the church by the same group that later destroyed the building.

“He was beaten and sustained head injuries and was treated at a local dispensary before being discharged,” Shamal said. “He is still recovering. Indeed, it is a big blow to the church, to have no place to worship and to lack a pastor. This is a big tragedy.”

Mubarak said that in some parts of Sudan, Islam has conquered the church. “In Northern Sudan, at a place called Dongola, the church building has been converted into a mosque and the few Christians forced to convert to Islam,” Mubarak said.

Church struggles extend even to land ownership. Maitias told Compass that after the signing of the Comprehensive Peace Agreement in 2005, the Sudan Inter-religious Council petitioned the government for a piece of land to be allocated to the church for worship. He said three churches were allowed to apply for land allocation for the purpose of building houses of worship: the Sudanese Church of Christ, the Episcopal Church of Sudan and the Catholic Church.

But to their surprise, the offer was given with some conditions: every year, the government must cross-check church operations and is free to repossess land at will.

“We as the church find our free operation not guaranteed,” Maitias said.

Andrea Amet Ubiu, who works with the Sudan Council of Churches in Khartoum, bought a piece of land from Zinab Adut in 1994 and constructed a temporary house at Salma village, which is about two miles from Khartoum.

“In 2005 the government began demolishing temporary structures in the area with a view of carrying out reallocations. To my surprise, when this [reallocation] was done, I was left out and was informed that the land I bought was not legitimate since the lady who sold the land to me was not entitled to it because she had no husband or children,” Ubiu said.

“But I knew it was a calculated move by the local authorities to deny me the land, because all along I had not supported the government before the signing of the peace agreement between the North and the South,” Ubiu added. “Life for me in Salma has been harsh, so I decided to forget the issue of the land and moved to a new location called Hagyouf area, five kilometers [three miles] from the town center.”

Maitias sees such discrimination as common for Christians in northern Sudan.

“Here in the North, the Church is discriminated [against] in almost everything, even including education,” Maitias said. “Christian institutions are not recognized by the government. Christian religious education is not taught in government schools. Christian programs are only given less than three hours in the national media on Sundays and Christian workers given only two hours for Sunday worship. Christmas celebrations are restricted to a day for celebrations, like marching with police security.”

Christians who wish to operate a restaurant during Ramadan must obtain a permit from authorities. “We always ask ourselves, why all this? Our identity as Christians is an anathema,” Maitias said. “Instead, the government prefers calling us ‘non-Muslims.’”

A dozen non-governmental organizations have been expelled from the country because of their vocal opposition to human rights abuses in Darfur.

WORLD EVANGELICAL ALLIANCE ASSEMBLY CLOSES IN THAILAND


More than 500 senior evangelical leaders gathering in Pattaya, Thailand from October 25-30, 2008, have wrapped up their General Assembly, after five days of intensive discussion to plan the way forward in world evangelization, reports Michael Ireland, chief correspondent, ASSIST News Service.

On Wednesday, delegates agreed upon six major resolutions setting out an evangelical response to religious liberty, HIV and Aids, poverty, peacemaking, creation care and the global financial crisis, according to a media release obtained by ANS.

“The worldwide financial turmoil is, at its root, evidence of what happens when too many are captivated by greed and put their faith in, and entrust their security and future aspirations to, a system animated by the maximization of wealth. Many legitimately feel betrayed,” read the resolution on the global financial crisis.

“While we hope that the painful consequences of the turmoil will be mitigated, our concern is that its impact will continue to permeate into more regions and economies of the world. We recognize that this economic crisis will have the most painful impact on the poor, who are the most vulnerable.

“We reaffirm our faith in God and acknowledge that He is in control. We repent when we have placed our trust in money, institutions and persons, rather than God. Our security is not found in the things of this world.”

The resolution called on Christians to care for the poor during the crisis and live simply and generously.

“The Body of Christ, His Church, is living with HIV,” stated the resolution on HIV, a major focus area for the World Evangelical Alliance (WEA). “With brokenness we admit that as Evangelical Christians we have allowed stigmatization and discrimination to characterize our relationships with people living with HIV. We repent of these sinful attitudes and commit to ensuring that they are changed.”

In the preamble to the resolution on the Millennium Development Goals, evangelical leaders stated, “In coping with the financial crisis of 2008, governments and international institutions have shown how quickly and effectively they can move to mobilize massive resources in the face of serious threats to our global, common economic well being.

“Yet one child dying of preventable causes every three seconds and 2.7 billion people barely sustained on an income of less than two dollars per day has yet to evoke a similar level of urgent response.

“We believe this to be an affront to God, a shame to governments and civil society, and a massive challenge to the witness and mission of the followers of Christ.”

World Evangelical Alliance (WEA) international director Dr Geoff Tunnicliffe told delegates that they faced additional challenges to fulfilling the Great Commission from radical secularism, postmodernism, declining Christianity at the same time as growing interest in spirituality, trafficking and migration.

He insisted, however, that great challenges also brought great opportunities for evangelical engagement.

“We see this tremendous growth and this seismic shift in the church around the world and we are excited to what God is doing as he raises up women and men around the world in so many different places,” he said.

“As we think about the global reality of the world in which we live, [there are] immense challenges but also immense opportunities.”

Dr Tunnicliffe also said that the WEA would remain committed to integral mission “or holistic transformation, a proclamation and demonstration of the Gospel”.

“It is not simply that evangelism and social involvement are done alongside of each other but rather in integral mission proclamation has social consequences. We call people to love and repentance in all areas of life,” he said.

He reaffirmed the WEA’s commitment to world evangelization.

“If anyone tells you that we’ve gone soft on world evangelization you can tell them that we are totally committed to world evangelization because it is only Jesus Christ that changes people’s lives,” he said.

A highlight of the week was an address from the Rev Joel Edwards, who was commissioned during the assembly as the new director of Christian anti-poverty movement Micah Challenge.

In his address, the former head of the UK Evangelical Alliance told delegates that the power to rehabilitate the word ‘evangelical’ lay in their hands.

“Whatever people think of evangelical Christians, if people are going to think differently about evangelicals the only people who can actually change their minds are evangelicals,” he said.

“We must reinvent, rehabilitate and re-inhabit what evangelical means as good news. We must present Christ credibly to our culture and we should seek to be active citizens working for long-term spiritual and social change.

“Words can change their meaning. If 420 million evangelicals in over 130 nations across the world really wanted it to happen, evangelical could mean good news.”

In another key address, the head of the Evangelical Fellowship of India, the Rev Richard Howell said that an identity anchored in Christ and a universal God was an evangelical non-negotiable in an age of pluralism.

“We have but one agenda: obedience to the Triune God revealed in Jesus Christ,” said Dr Howell. “We are evangelical Christians for the sake of God.”

“Our identity has to be related back to God. Unless we do that, we will never know who we are. Our identity comes from God and God alone.”

“The Christian belief in the oneness of God implies God’s universality, and the universality implies transcendence with respect to any given culture.

“Christians can never be first of all Asians, Africans, Europeans, Americans, Australians and then Christians.”

The assembly also heard from the Chair of the Lausanne Committee for World Evangelization (LCWE), Douglas Birdsall.

The WEA is collaborating with the LCWE in its major Cape Town 2010 meeting, which will bring together 4,000 evangelicals to assess the next steps in realizing the movement’s vision of ‘the whole church taking the whole gospel to the whole world’.

“You might ask is there a need for an international congress that deals with world evangelization,” Birdsall told the assembly. “I would say that throughout history, such a gathering is only necessary when the future of the life of the church is threatened by some type of challenge – either internal challenge or external pressure.”

The assembly also saw the launch of the WEA Leadership Institute, a brand new initiative to see the leaders of the WEA’s 128 national alliances trained to serve and proclaim Christ within some challenging contexts.

“Leading an Evangelical Alliance is not easy,” commented Dr Tunnicliffe. “That’s why we want to provide them with the relevant training and resources.”

Also commissioned during the week was the new leader of the WEA’s Religious Liberty Commission, Sri Lankan national Godfrey Yogarajah.

Dr Tunnicliffe rounded up the assembly with a call to evangelicals to keep in step with God’s work on earth.

“It is my prayer that we in our community will be women and men who live with divine purpose within our lives, that we will be good leaders envisioned by God to make a difference in the world,” he said.

“The most important thing that you can do with your [life] is to integrate it into the never ending story of God’s kingdom. God’s already at work in the world. He’s doing things. We just need to align with what He is doing.”

World Evangelical Alliance is made up of 128 national evangelical alliances located in 7 regions and 104 associate member organizations. The vision of WEA is to extend the Kingdom of God by making disciples of all nations and by Christ-centered transformation within society. WEA exists to foster Christian unity, to provide an identity, voice and platform for the 420 million evangelical Christians worldwide.

INDONESIA: THEOLOGY STUDENTS MOVE TO ABANDONED OFFICE


Evacuated after Muslim attack in July, Christians forced to leave campground.

JAKARTA, October 27 (Compass Direct News) – Over 1,000 students forced from the Arastamar Evangelical School of Theology (SETIA) in East Jakarta have now moved into an abandoned mayor’s office in Jakarta after management at the Bumi Perkemahan Cibubur (BUPERTA) campground demanded that 700 students temporarily resident there had to leave by Oct. 14.

Urged on by announcements from a mosque loudspeaker to “drive out the unwanted neighbor,” hundreds of protestors shouting “Allahu-Akbar [“God is greater]” and brandishing machetes, sharpened bamboo and acid had forced the evacuation of staff and students from the SETIA campus in Kampung Pulo village on July 26 and 27, following a misunderstanding between students and local residents. Attackers injured at least 20 students, some seriously.

Key among motives for the attack was that area Muslims felt “disturbed” by the presence of the Christian college. They want it to be moved to another area.

Following the evacuation, some students were temporarily billeted in church offices, while others slept in the lobby of Indonesia’s parliament building. Officials then moved 600 female students to the BUPERTA campground, where they were later joined by 100 male students. A further 400 male students remained at a migrants’ center in Bekasi, while 32 post-graduate students were accommodated in a housing complex in Kota Wisata, not far from the campground in Cibubur.

Campground manager Umar Lubis sent a letter to SETIA principal Matheus Mangentang on Oct. 6 ordering the students to vacate the premises in advance of a pan-Asian scouts jamboree scheduled at the facility for Oct. 18-27. Lubis sent a copy of the letter to Fauzi Bowo, the governor of Jakarta.

Mangentang initially protested, since the campground could accommodate up to 30,000 people and there would only be 300 participants in the jamboree. He also noted that despite an agreement reached in September, Bowo had failed to repair and extend bathroom facilities in an abandoned mayoral office in Jakarta offered for use by the staff and students.

When the council made no attempt to begin renovations on the mayor’s office, Mangentang himself hired bricklayers and carpenters to install more toilets, repair damaged ceilings on two floors of the building and erect partitions to create 13 classrooms.

The students last week moved into the abandoned mayor’s office. But the building still lacks many basic amenities, according to staff. Students carry well water into the building in large plastic drums for showers, toilets, laundry and cooking.

One staff member told Compass that the water was slimy to the touch and not suitable for showering.

 

Broken Promises

Bowo had also promised Mangentang that the students could return to their original campus at the end of the Muslim fasting month of Ramadan. He then promised to find a site for a new campus and provide an official building permit, but at press time there was no evidence of action taken to fulfill these promises.

Mangentang has refused to cover costs for the campground, which now amount to some 580.7 million rupiah (US$58,418), on the grounds that since they were unfairly evicted from their campus, the governor’s office should fund the cost of temporary relocation.

Cibubur campground officials had also charged SETIA 50,000 rupiah (US$5) per day for water. When Mangentang refused to pay this fee, officials restricted the water supply so that there was not sufficient water available for laundry and shower facilities for the students.

Bowo had committed to paying those bills but said he must first meet with the local House of Representatives to request funding for them and any other expenses that would be incurred by providing a new building site and campus for SETIA.

SETIA staff sought advice from the National Commission on Human Rights in Jakarta on Sept. 7. The commission then wrote to the superintendent of police in Jakarta, asking for a police escort to return the students safely to their campus, but the superintendent did not respond. Neither has any investigation been carried out against the residents who violently attacked staff and students in July.

Last year the Muslim extremist Islamic Defenders’ Front demonstrated in front of the college, accusing it of having misapplied its permit.

Since 2007, protestors have held six demonstrations. On March 7, 2007, more than 200 Muslims set fire to construction workers’ quarters in an effort to keep SETIA from adding a fifth dormitory.

Three days later, some 300 people gathered to protest the construction, demanding that the school close. They claimed it was disturbing area residents when students sang during their classes and that students were evangelizing people in the area.

Government officials have brokered talks between the conflicting parties, without success.
