Cotton is one of the most important fibre crops playing a key role in economic and social affairs of the world. Water is a critical factor which influences on growth and yield of the cotton crop. Scarcity of water has put tremendous pressure on scientists to introduce drought tolerant cotton varieties. This study was aimed to determine water stress effects on the growth and yield of cotton. The present study was carried out to examine the effect of number of irrigations on the growth and yield of cotton during 2014. The field trial was conducted at the Experimental Fields of Agronomy Section, Agriculture Research Institute, Tandojam, Pakistan. A three replicated Randomized Complete Block Design (RCBD) was employed to layout the experiment having plot size of 2.5 m × 5 m (12.5 m2). Four cotton varieties i.e. NIAB-78, Shahbaz-95, Sindh-1 and TH-224/87 were chosen for this study based on their frequent farmer usage. All the agronomic practices were performed according to standard procedures. Results showed that all the growth and yield components of cotton were significantly (P 0.05) affected by irrigation frequencies. The cotton crop irrigated six times at 21 days interval showed better results with 138.16 cm plant height, 1.45 monopodial branches per plant, 21.83 sympodial branches per plant, 44.58 bolls per plant, 33.86% G.O.T., and 26.97 mm staple length, 149.84 g seed cotton yield per plant and 2271.16 kg·ha-1 seed cotton yield. This study concluded that variety NIAB-78 showed superiority over Shahbaz-95, Sindh-1 and TH-224/87 in almost all the characters of economic importance, and the cotton crop received 6 irrigations at 21 days interval resulted in significantly economical overall performance as compared with 5 irrigations or 4 irrigations with higher seed cotton yield.

About 20% of injuries presented in the emergency room that require surgical repair involve the hand. Most of these injuries result from sharp objects such as glass and knives, and blades in case of suicide. In Pakistan, the most common injuries occur at the junction between the transverse distal crease on the wrist and the forearm muscles (zone 5). Wrist injuries are difficult to repair since they result in the tendon, ulnar and median nerve and arteries abrasion. In addition, an inadequate approach could damage abrasion and swelling of the flexor muscles, risking the functioning of the hand. A good outcome necessitates prioritizing the flexor muscles to avoid swelling and hand dysfunction. The objective of this study is to investigate the effectiveness of Belfast rehabilitation in the treatment of flexion tendon injury. The process of rehabilitation was carried out for a period of 2 years. Using the Belfast regime as a post-rehabilitation regime ensures no adhesion formation, swelling, or delayed healing.

近年来,全世界都在抓紧建设运行速度超过500公里/小时的高速列车。尤其是子弹头列车和高速列车在中国已被广泛使用。此外,由于列车的高速移动性,以及人们对高速数据服务的需求日益增加,使得获取准确的信道信息和开发高速铁路(HSR)通信的高效广播系统(如可靠性,安全列车运行和乘客通信)成为关键。满足乘客在高速列车场景下对无线通信的需求是一个具有挑战性的问题。例如,2017年中国推出世界上最快、最长的高速列车,连接北京和上海两地,总长达1318公里。此列车最高时速可达500公里/小时,该路线的容量估计约为每天22万乘客,所有这些乘客都需要稳定和高质量的互联网连接。高速铁路的发展给乘客带来了极大的便利,然而乘客对可靠的无线和数据连接的需求也在增加。在过去几年中,由于智能手机、平板电脑、笔记本电脑和许多其他无线数据消费设备的急剧发展,数据流量呈指数级增长。随着全球移动数据流量的增长,未来对无线数据流量的需求将会更大,预计到2018年每月增长到15.9艾比特,与2014年相比增长约6倍。此外,估计到2018年时,增加的连接设备数量将达到102亿。在基站和接入点之间传输的数据是来自火车上众多不同旅客的复合流。一般来说,不同的旅客可能有不同的需求。例如,某些个人正在运行文件传输协议下载或基于缓存的数据推送服务,这些服务对平均速率很敏感并且可以延迟;而另一方面,其他旅行者可能正在进行语音通信或智能娱乐,这对延迟比较敏感。换句话说,基站和接入点之间传输的复合数据是一组具有不同服务质量要求的数据流,例如同时具有唯一信息速率和最大容忍延迟。根据无线服务厂商的逐步宣布,每个传输服务需要更多的吞吐量,以适应更高信息速率的客户,同时保持服务质量。为此,我们可以使用多用户控制堆栈和资源分配策略使可访问资源更有效地利用。然而,随着列车移动速度增加到500公里/小时,之前的这些系统无法应对数据包丢失,快速的小区切换和多普勒频移等问题,以满足服务需求并保证可靠的列车运行。因此,为了匹配列车如此高的速度,网络设计、硬件设备和软件算法是必要的。高速铁路的发展为乘客提供了极大的方便。但是,现有的GSM-R等铁路通信系统并不适合高速列车与地面之间的通信。正如GSM-R制造商所说,GSM-R的生命周期将在2025年结束,而国际铁路联盟(UIC)表示,开发用于铁路的下一代移动通信系统将绕过第三代移动通信[5]。我们已应用众多技术,来从根本上提高高速铁路通信系统的容量和可靠性。除此之外,MIMO技术在高架桥地形中的高速铁路(HSR)无线通信系统中可能不太成功。当配备大量发射天线时,系统设备成本的影响更为严重。假设,极限将以对数形式展开,并最终与固定相关信道上的发射天线数量相关。那么,对于最优的视距(LOS)衰落信道的情况,发射天线数量的增加没有产生事实上的变化,多个天线接收将完全失去效果。相反,由于高速运动产生多普勒影响还会引起严重的载波间干扰(ICI)。5G通信系统目前正在探索中。欧盟、美国、韩国、中国和日本已经建立了第五代改进协会,HSR场景已被认为是第五代典型场景之一。根据这些进展以及相关的关键技术的发展,我们应该被认真研究大规模MIMO策略和相应的信道建模。近来,大规模MIMO技术因其显着提高频谱效率,能量效率和系统强度的优势而使许多研究人员向往。在大规模MIMO系统中,发射机和接收机都配备有大量的天线元件(通常为数十甚至数百个)。应该注意,发射天线可以分布在相同或不同的应用中。而且,大量的接收天线可以由一个设备拥有或分配给许多设备。大规模MIMO系统不仅可以享受传统MIMO系统的优势,而且还可以显着提高频谱效率和能量效率,因为当天线数量足够大时,大规模MIMO中的信道间干扰(ICI)是平均的大数定律(LLN)。因此,信道能力可以通过简单的匹配滤波波束成形或接收器来实现。大规模MIMO是下一代无线通信系统的一项候选技术。最近,这项技术引起了很多专家的注意,大规模MIM0(也称为大规模天线方案)可以满足高速铁路(HSR)无线通信系统列车-地面信息传输的要求。大规模MIMO技术是一种满足需求且有前景的候选技术。通过为基站装备大量数目,例如数十到数百个天线,可以用相同的时间-频率资源来服务众多的终端,而没有终端的用户间干扰。大量的天线也获得了大阵列的优势,即增强了接收信号能力,因此可以实现更好的覆盖。另一方面,我们可以使用来自基站和终端的发射功率来满足能量效率需求。理论上已经证明,配备大量基站天线的系统可以在链路一致性、数据速率和辐射能量效率方面显着提高性能。实际上,由于这种系统的物理约束和复杂性,基站的天线数量不能无限的变大。而且,成本也应该考虑在内。我们知道,在基站增加更多的天线通常价格低廉,而且额外的数字信号处理单元也变得越来越便宜。而且,现有网络中80%的功率在基站处消耗

Electronic banking has provision networks that replaces and replicated various activities currently executing by the bank. Hence e-banking now plays a vital role to carry out the individual as well as corporate financial activities execution. Even e-banking activities based on the internet or virtual private networks own by the bank, therefore communication channel, distribution channel and transactions channel must be secure. The research article explores the current trends in the e-banking uprising that has set a goal in the Pakistani banking sector to provide any easy interface to their customers which avail the e-banking services without any physical presence in the bank vicinity. This empirical study was carried out in Pakistan which indicating the current issues encounter by the e-banking application in various banking industries. The analysis in this paper further reveals that approachability of internet in banking sector makes customer reluctant to access their bank accounts electronically. The usage of e-banking significantly affects the customer trust due to unavailability of cyber security.

Quantification of Radiation Use Efficiency and Yield of Wheat as Influenced by Different Levels of Nitrogen and Water Stress under Semi-Arid Conditions of Faisalabad

引用

Agricultural Sciences 2018年第7期9卷 873-887页

作者： Muhammad Ishfaq Usman zulfiqar Muhammad Ahmad Ch Basit Mustafa ali Hamed Muhammad Shafique Aslam Muhammad Zohaib Anjum Department of Agronomy University of Agriculture Faisalabad Pakistan Department of Forestry and Range Management University of Agriculture Faisalabad Pakistan

Crop production is greatly influenced by water and nutrition stress in semi-arid areas. Nitrogen and water are two most important yield limiting factors which effect economic production of wheat. Drought initiates when large area of land suffers from absence of precipitation for temporary periods. Though, not only water scarceness but also low relative humidity and high temperature are other climate factors which induce drought condition. Whereas Effective nutrition (nitrogen) maintains crops metabolic activities and has the potential to lessen drought stress. According to study carried out to explore the influence of varying levels of potential soil moisture deficit (PSMD) and nitrogen, an experiment was planned at agronomy research area, University of Agriculture, Faisalabad. It was laid out in randomized complete block design (RCBD) with split plot arrangement, and replicated thrice. Two factors: potential soil moisture deficit levels (I1: irrigation at 50 mm PSMD, I2: irrigation at 75 mm PSMD and I3: irrigation at 100 mm PSMD) were randomized in main plots, while sub plot nitrogen levels {control (No nitrogen), 50, 100 and 150 kg N ha-1} were randomized. Adequate nitrogen application along with sufficient irrigation management gave highest yield. Under water deficit conditions adequate nitrogen application ameliorates the drought stress. Highest plant height (86.27 cm), number of productive tillers (320.0), grain·spike-1(49.73), test weight (50.55 g) and grain yield (6.72 t·ha-1) were observed with 75 mm PSMD and 150 kg·ha-1 application of nitrogen. While radiation use efficiency for dry matter accumulation of wheat ranged from 1.53 - 1.87 g·MJ-1 whereas, radiation use efficiency for grain yield ranged from 0.421 - 0.473 g·MJ-1. Results revealed that highest RUE obtained I3 (75 mm PSMD) and nitrogen application at 150 kg·ha-1. Judicial application of irrigation and fertilizer not only boosts the yield but also saves resource and increases former output.

Determinants of Health Care Seeking Behaviors in Puerperal Sepsis in Rural Sindh, Pakistan: A Qualitative Study

引用

Open Journal of Preventive Medicine 2020年第9期10卷 255-266页

作者： Shabina Ariff Fatima Mir Farhana Tabassum Farrukh Raza Atif Habib ali Turab Amnesty LeFevre Linda A. Bartlett Sajid Bashir Soofi zulfiqar A. Bhutta Department of Paediatric and Child Health Aga Khan University Karachi Pakistan Center of Excellence in Women & Child Health Aga Khan University Karachi Pakistan Department of International Health Johns Hopkins Bloomberg School of Public Health Baltimore MD USA

Background: Puerperal sepsis (PS) is one of the major causes of maternal death, contributing to 26,000 deaths per year in developing countries. Early recognition and treatment are essential to managing PS, but numerous social, cultural and technical barriers prevent or delay access to care and necessary medical attention. Through this qualitative study, we identified barriers to care seeking for puerperal sepsis among recently delivered women in Matiari, Pakistan. Methods: We conducted 20 in-depth interviews among recently delivered women with and without sepsis and their family members in September 2012. Key informant interviews were conducted with 14 healthcare providers and traditional birth attendants. The themes used for content analysis were knowledge of danger signs, factors affecting care seeking and local treatment practices for postpartum sepsis. Results: A total of 34 interviews were conducted. Recently delivered women, their family members and traditional birth attendants were unaware of the word PS or the local translated term for PS. However, they were familiar with most of the individual symptoms associated with PS. Healthcare providers were aware of the condition and the associated symptoms. The healthcare providers’ understanding of the seriousness of PS was directly proportional their age and clinical experience. The most common barriers to care seeking was the division of labor within the household, obtaining permission from the primary decision maker, access to transportation, lack of financial resources and support from family members. Conclusion: To improve maternal care seeking behaviors for PS, interventions focusing on increasing knowledge of PS, addressing gender inequality, implementing an affordable community transport service and enhancing TBA’s knowledge and skills to manage PS need to be implemented.
