Background: Proximal humerus fractures, are a major medical issue that are relatively prevalent. 4-5% of all fractures are proximal humeral fractures, most of which involve older and osteoporotic individuals. Objectives: To compare the functional outcome of philos plate vs. external fixator in the management of proximal humerus fracture. Material and Methods: A retrospective comparative study was conducted at the Department of Orthopaedic Surgery, Ghurki Trust Teaching Hospital, Lahore. From November 23, 2022, to May 23, 2023. After approval from the hospital's ethical board, 112(56 per group) patients were included in the study through an emergency. Informed consent was taken from parents. We stratified patients into two groups. Group A received the treatment of Philos, while Group B received the external fixator treatment. Functional outcome was assessed at the end of 3 months postoperatively using constant shoulder score. The collected data were entered and analyzed accordingly using SPSS version 27. Results: In the current study, a total of 112 patients included underwent two surgical interventions, among these, 56 patients underwent Philos plating while an equal number of patients underwent external fixation. In Group A and B, the majority were males (37:47) out of 112. The mean age of patients was equal in both groups (Group A=44.36±11.71), and the mean age of patients was (Group A=44.88±10.05), ranging from 20 to 80 years. In Group A, the average BMI was less than 24.29±4.23, ranging from 18-35 kg/m2, compared to Group B, 28.89±3.77, ranging from 22-35 kg/m2. 38(67.9%) were effected from right side as in Group A while 41(73.2%) were effected from right side in Group B. Majoruty 28(50.0%) had history of RTA in Group A while patients 24(42.9%) were observed with history of RTA in Group B25(44.6%) cases reported excellent outcome, 6(10.7%) reported very good outcome, 16(21.4%) good, 7(12.5%) fair and 2(3.6%) poor outcome in Group A. In Group B, 36(64.3%) excellent, 7(12.5%) very good, 12(21.4%) cases reported Good and 1(1%) reported fair outcome. So it is concluded that 25(44.6%) cases reported excellent outcome in Group A, comparatively low as compared to Group B 36(64.3%). Only age was significantly associated with excellent outcomes as p<.05. Conclusion: It is concluded that External fixation demonstrated a better outcome as compared to Philos Plating, so in Orthopaedic practice, External fixation should be preferred for patients diagnosed with proximal humerus fracture to get better results and reduce the complications.

Objective. This study aimed to explore the "In Vitro" antimicrobial activity of extracts of leafy stems of M. charantia on a few multi-resistant germs. Methods: Phytochemical screening of M. charantia leafy stem powder was carried out by the methods of colorimetry and thin layer chromatography followed by the search for larval cytotoxicity. The sensitivity test by the solid medium diffusion method and the search for resistance genes were carried out on E. coli ATCC25922 then on K. pneumoniae, K. oxytoca, and E. coli isolated from hospital samples. Flavonoids, alkaloids, stetol-terpenes and saponosides were identified in the powder of the leafy stems of M. charantia. Results: No cytotoxic effects were observed in Artemia salina at the LC 50 of 6.25 mg/ml. With the exception of Ciprofloxacin, Ertapenem and Ceftriaxone which showed respective resistance rates of 60%, 90% and 90%, absolute resistance, i.e. 100%, was observed against Ampicillin, Aztreonam, and Augmentin. The resistance genes present in the bacterial strains studied were SHV, TEM, CTX-M1 and CTX-M15. The sensitivity tests carried out indicate that the aqueous and ethanolic extracts were active on the strains tested with respectively average inhibition diameters of between 9 ±1 and 14 ±1 mM then between 9 ±1 and 12 ±1 mM. Conclusion: This study revealed antimicrobial activity of each of the aqueous and ethanolic extracts of the leafy stems of M. charantia of the multidrug-resistant bacterial strains studied.

Compressed stabilised earth blocks (CSEBs) are produced from inorganic soil compacted under high pressure to create a solid block. This study explores the potential benefits of incorporating coconut coir into CSEBs to enhance their mechanical properties and water absorption. It focused on optimising the mix design of CSEBs with coconut coir reinforcement to achieve maximum compressive strength and minimise water absorption. The study employs a quadratic model to analyse the effects of moisture ratio, cement ratio, and coconut coir content on compressive strength. The results indicate that the moisture content and cement ratio significantly affect compressive strength, while coconut coir content is insignificant. However, the findings suggest that adding coconut coir can reduce water absorption in CSEBs. The analysis of variance reveals that the model is significant, with a predicted R-squared of 0.5884 and an adjusted R-squared of 0.6592. The results contribute to the growing research on using coconut coir as a reinforcement material in CSEBs, offering practical recommendations for their application in building construction.
压缩稳定土块(CSEBs)是由无机土壤经高压压实而成的固体块体。本研究探讨了在 CSEB 中加入椰糠以提高其机械性能和吸水性的潜在好处。研究重点是优化椰糠加固 CSEB 的混合设计,以达到最大抗压强度和最小吸水率。研究采用二次模型分析了水分比、水泥比和椰糠含量对抗压强度的影响。结果表明,水分含量和水泥比对抗压强度有显著影响,而椰糠含量则不显著。然而,研究结果表明,添加椰糠可以减少 CSEB 的吸水率。方差分析显示该模型是显著的,预测 R 方为 0.5884,调整 R 方为 0.6592。这些研究结果有助于推动在 CSEB 中使用椰糠作为加固材料的研究,并为其在建筑施工中的应用提供了实用建议。

The rising demand for charitable organizations is fueled by increasing numbers of people in need, growing inequalities, and crises such as wars, natural disasters, and inflation. Charities face the challenge of securing sufficient funding, worsened by increased competition and a decline in public donation behavior. Developing new marketing strategies is crucial, particularly leveraging social media in the digital age. While previous research underscores the persuasive power of emotional advertising, gaps remain in understanding which emotions most effectively drive donation intentions. This thesis explores the impact of emotional advertising appeals in digital charity marketing campaigns on donation intention, investigating whether positive or negative appeals are more influential. Additionally, it examines gender differences in altruism and how altruistic values moderate the effects of negative emotional appeals on guilt and shame. An experimental research design was used, with a between-subject design involving three groups exposed to positive, negative, or neutral advertising stimuli. The sample consisted of 200 respondents over 18 years old, representative of the Indonesian population. Participants were randomly assigned to groups and answered questions on donation intentions, altruistic values, emotional reactions, and demographics. Statistical analysis revealed that positive and negative advertising appeals elicit different emotions. Surprisingly, no significant difference was found between positive and negative appeals on donation intention, suggesting emotional orientation does not influence donation intentions. The study also found stronger altruistic beliefs in women and that altruistic values amplify guilt and shame in response to negative emotional appeals.
需要帮助的人越来越多,不平等现象日益加剧,战争、自然灾害和通货膨胀等危机层出不穷,这些都助长了对慈善组织日益增长的需求。慈善组织面临着如何获得充足资金的挑战,而竞争的加剧和公众捐赠行为的减少又加剧了这一挑战。制定新的营销战略至关重要,尤其是在数字时代利用社交媒体。虽然以往的研究强调了情感广告的说服力,但在了解哪些情感能最有效地推动捐赠意向方面仍存在差距。本论文探讨了数字慈善营销活动中情感广告诉求对捐赠意向的影响,研究了正面诉求还是负面诉求更有影响力。此外,论文还探讨了利他主义的性别差异,以及利他主义价值观如何调节负面情感诉求对内疚和羞愧的影响。本研究采用了实验性研究设计,包括三组受试者,分别接受正面、负面或中性的广告刺激。样本由 200 名 18 岁以上的受访者组成,他们是印度尼西亚人口的代表。受试者被随机分配到各组,并回答有关捐赠意向、利他价值观、情绪反应和人口统计学的问题。统计分析显示,正面和负面的广告诉求会引发不同的情绪。令人惊讶的是,正面和负面广告诉求在捐赠意向上没有发现明显差异,这表明情感取向不会影响捐赠意向。研究还发现,女性的利他主义信念更强,而且利他主义价值观会放大对负面情感诉求的内疚感和羞耻感。

The aim of this work is design and implementation of a lecture alert system for Computer Science Department which makes use of Short Message Service (SMS) to enable lecturers to know when they have lectures and also deliver the venue, department, day, date and time to their phones. The motivation for this work is due to the challenges of the consistence report of errors in the process of filling and allocating the lectures on the time table, lack of effective record system or database system to store the record of time table and clashes of lecture because one venue can be allocated to different lecturers at the same time. The methodology that will be employed in this study is the object-oriented analysis and design methodology (OOADM) which will make use of the following programming languages; JavaScript for controls and flexibility, PHP for effective linking and communication with the database machine, HTML for browser communicator, a database machine, MySQL, and macromedia flash (11.0) for the video output display. The expected result that will be obtained is to a design a conventional lecture alert system using Short Messaging Service (SMS), also to provide a new method of checking lectures using mobile phone short messaging service work and to alert students ahead of their lectures and inform them of the venue of the lecture.
这项工作的目的是为计算机科学系设计和实施一个讲座提醒系统,该系统利用短信服务(SMS)使讲师了解他们的讲座时间,并将地点、部门、日期和时间发送到他们的手机上。这项工作的动机是由于在填写和分配时间表上的讲座过程中出现的错误报告的一致性、缺乏有效的记录系统或数据库系统来存储时间表的记录以及讲座的冲突(因为一个场地可以同时分配给不同的讲师)等挑战。本研究采用的方法是面向对象的分析和设计方法(OOADM),将使用以下编程语言:JavaScript 用于控制和灵活性,PHP 用于有效链接和与数据库机通信,HTML 用于浏览器通信,数据库机、MySQL 和 macromedia Flash (11.0) 用于视频输出显示。预期成果是设计一个使用短信服务(SMS)的传统讲座提醒系统,同时提供一种使用手机短信服务检查讲座的新方法,并在讲座前提醒学生,通知他们讲座的地点。

Background: The prevalence of bacterial infections in children is increasing by the day, this gives a cause for concern regarding the high rate of bloodstream infection (BSI) and associated mortality in developing countries. Physical signs and symptoms may be useful but have limited specificity which would be addressed with bacteriologic blood culture. This study was aimed at determining the etiologic agents of bacteremia and the prevalence in pediatric patients aged 0-5years. Methods: Two hundred and sixty- two (262) blood samples were analyzed from children aged 0-5years, attending hospitals within Bauchi metropolis with features suggestive of septicemia. Samples were collected under aseptic conditions and automated blood culture was done on BacT/ALERT 3D Biomerieux, Germany. Positive blood culture was sub-cultured on blood agar and MacConkey agar and identified on Vitek2 (bioMѐrieux, France) automated system after gram staining. Changes in pathogen distribution according to age and gender were determined by the chi-square test and statistical significance confirmed if a two-tailed p-value was not more than 0.01. Results: Bacteria was isolated in 119 (45.4) of samples with highest rate among neonates 54(45.3). Staphylococcus aureus 21 (17.6) was the most predominant organism isolated across all age groups with a higher occurrence in patients<1year old. A chi-square test of independence for culture positivity and age/gender at p<.01 was not significant Conclusion: In this study both Gram-positive and Gram-negative bacteria are implicated in pediatric bloodstream infections. Staphylococcus aureus was the most predominant organism followed by members of the Enterobacterales (Enterobacter spp, Klebsiella spp and Escherichia coli).
背景:儿童细菌感染的发病率与日俱增,这引起了人们对发展中国家高血流感染(BSI)率和相关死亡率的担忧。体征和症状可能有用,但特异性有限,这需要通过细菌血液培养来解决。本研究旨在确定菌血症的病原体以及 0-5 岁儿童患者的发病率。研究方法分析了 262 份血液样本,这些样本来自包奇市内各医院就诊的 0-5 岁儿童,其特征表明这些儿童患有败血症。样本在无菌条件下采集,并使用德国Biomerieux公司的BacT/ALERT 3D进行自动血液培养。阳性血培养物在血琼脂和麦康凯琼脂上进行亚培养,并在革兰氏染色后用 Vitek2(法国 bioMѐrieux)自动系统进行鉴定。病原体分布在年龄和性别上的变化通过卡方检验确定,如果双尾 p 值不超过 0.01,则具有统计学意义。结果119(45.4)份样本中分离出了细菌,其中新生儿的细菌分离率最高,为 54(45.3)。金黄色葡萄球菌(21(17.6))是所有年龄组中分离出的最主要菌种,在 1 岁以下的患者中发生率较高。培养阳性率与年龄/性别的独立性的卡方检验(P<.01)不显著:在这项研究中,革兰氏阳性菌和革兰氏阴性菌都与小儿血流感染有关。金黄色葡萄球菌是最主要的细菌,其次是肠杆菌科细菌(肠杆菌属、克雷伯氏菌属和大肠埃希氏菌)。
