Web GIs-Based Temporal Analysis of Climatic Factors Impacting Heat stroke in Karachi

Journal of Geographic Information system 2024年第1期16卷 61-69页

作者： Ali Atif mahnoor Rehman muhammad butt syed mahmood shahid Ghazi Rashid mehmood Department of management Victoria University Sydney Australia Department of Geography Government College University Lahore Pakistan Department of space science University of the Punjab Lahore Pakistan Centre of Geographic Information system University of The Punjab Lahore Pakistan

This study focuses on the impact of climate change, specifically the increasing threat of heatwaves, in Pakistan, with a particular emphasis on the city of Karachi. The Pakistan meteorological Department (PmD) analysed a century of climatic data to reveal warming trends, attributing them to human-induced factors. The vulnerability of Pakistan to climate change is highlighted, given its warm climate and location in a region where temperature increases are expected to surpass global averages. The study examines the past three decades, noting a significant rise in the frequency of hot days, especially in Karachi, where heatwaves have become more prevalent. The aims and objectives of the study involve identifying temporal changes in temperature, rainfall, humidity, and wind speed from 1984 to 2014 in Karachi. The literature review emphasizes the health implications of heatwaves, citing increased mortality during such events globally. The study incorporates a comprehensive temporal analysis, addressing gaps in previous research by considering multiple climate indicators responsible for heatwaves. The methodology involves statistical analyses, including linear regression and Pearson correlation, applied to temperature data and urbanization parameters. Results indicate an increasing trend in heat index temperature, with heatwave vulnerability peaking in the last three decades. Heat Index Temperature Anomalies show a clear surge, emphasizing the need for new indices to control critical heat stress conditions. The study concludes that tropical climate variability, particularly heat index, is linked to extreme hot days, urging measures to reduce population vulnerability. The findings underscore the importance of policy strategies, such as integrated coastal zone management, to mitigate the adverse health effects of heatwaves in Karachi’s vulnerable population.

肉品质下降是肉发生脂质过氧化反应引起的。饲料中添加抗氧化剂可减少脂质过氧反应化和改善屠宰后肉的氧化稳定性。研究结果表明,给肉鸡饲喂添加α-生育酚醋酸酯(200mg·kg-1)与α-硫辛酸(25、75、150mg·kg-1)可增加肉的氧化稳定性及降低脂肪沉积。随着饲料中添加α-硫辛酸浓度的增加,肉中总酚含量和α-硫辛酸的含量增加。添加α-硫辛酸和α-生育酚乙酸酯,肉中的蛋白质含量没有改变。DPPH和TBA检测的结果表明,饲料中添加α-硫辛酸和α-生育酚乙酸酯,增强了鸡肉的抗氧化活性。给肉鸡饲喂食添加氧化油的饲料(4%),可导致其氧化稳定性降低。

大豆黄酮即大豆植物雌激素,是一种强抗氧化剂,具有多种生物活性。研究通过在肉种鸡产蛋后期饲喂大豆苷元来证实大豆黄酮提高产蛋率的作用,并通过相关基因表达的变化和肝脏的抗氧化状态来阐明这个过程的机制。选择460日龄的肉种鸡300只,随机分成3组(每组100只,设10个重复,每个重复10只),分别饲喂基础日粮(对照组,CON)或在基础日粮中添加大豆黄酮5mg·kg-1(低剂量,L)或10mg·kg-1(高剂量,H)。预饲期1周,试验期15d。试验结果表明,添加大豆黄酮的高和低剂量均显著提高产蛋率(P0.05)。血清雌激素表现出剂量依赖性减少,且添加大豆黄酮高剂量组与其他组相比差异显著(P0.05)。大豆黄酮显著降低血清丙二醛含量(PsOD)活性和丙二醛的含量并没有显著影响(P>0.05)。实时PCR分析结果表明,大豆黄酮组的母鸡随着产蛋率的增加,肝脏卵黄蛋白原-Ⅱ表达显著下降(PmRNA的表达显著上升(P0.05)。结果表明,添加大豆黄酮可通过提高抗氧化能力和不断改变肉鸡肝相关基因的转录来提高产蛋率。

APPLICATION OF ImPROVED PRODUCTION ACTIVITY CONTROL ARCHITECTURE FOR sHOP FLOOR INFORmATION sYsTEm IN DIGITAL mANUFACTURING

引用

Chinese Journal of mechanical Engineering 2006年第4期19卷 483-486页

作者： sHAHID Ikramullah butt school of mechanical and Vehicular Engineering Beijing Institute of Technology Beijing 100081China

shop floor control （sFC） is responsible for the coordination and control of the manufacturing physical and information flow within the shop floor in the manufacturing system. Weaknesses of the production activity control （PAC） architecture of the shop floor are addressed by the maglica＇s new system architecture. This architecture gives rise to unlimited number of movers and producers thus evolving more complex but decentralized architecture. Beijing Institute of Technology - production activity control （BIT-PAC） architecture introduces an idea of sub-producars and sub-movers thus reducing the complexity of the architecture. All the equipments including sub-producars and sub-movers are considered to be passive in the proposed shop floor information system. The dissemination of information from sub-producers and sub-movers is done manually through a PC. Proposed BIT-PAC sFC architecture facilitates the information flow from shop floor to the other area of the organization. Effective use of interact information services （IIs） and sQL2000 is done along with the *** technology to implement the application logic. Applicability of the software based on BIT-PAC architecture is checked by running application software on a network PC that supports the dynamic flow of information from sub-producers and sub-movers to the other parts of the organization. Use of software is also shown at the end for BIT training workshop thus supporting the use of sFC architecture for similar kind of environments.

The study of heat transfer is of significant importance in many biological and biomedical industry *** investigation comprises of the study of entropy generation analysis of the blood flow in the arteries with permeable walls. The convection through the flow is studied with compliments to the entropy generation. Governing problem is formulized and solved for low Reynold's number and long wavelength approximations. Exact analytical solutions have been obtained and are analyzed graphically. It is seen that temperature for pure water is lower as compared to the copper water. It gains magnitude with an increase in the slip parameter.
