Circulation Pattern Controls of Summer Temperature Anomalies in Southern Africa

Advances in Atmospheric Sciences 2024年第2期41卷 341-354页

This study investigates the relationship between circulation patterns and austral summer temperature anomalies in southern Africa. The results show that the formation of continental lows tends to increase the thickness of the lower atmosphere. Further, the distinct variabilities of high and low pressure under the circulation types, influence air mass advection from the adjacent oceans, as well as atmospheric stability over land. Stronger anticyclonic circulation at the western branch of the Mascarene high-pressure system enhances the low-level cold air advection by southeast winds,decreases the thickness, and lowers the temperature over a majority of the land in southern Africa. Conversely, a weaker Mascarene High, coupled with enhanced cyclonic activity in the southwest Indian Ocean increases low-level warm air advection and increases temperature anomalies over vast regions in southern Africa. The ridging of a closed South Atlantic anticyclone at the southern coast of southern Africa results in colder temperatures near the tip of southern Africa due to enhanced low-level cold air advection by southeast winds. However, when the ridge is weak and westerly winds dominate the southern coast of southern Africa, these areas experience temperature increases. The northward track of the Southern Hemisphere mid-latitude cyclone, which can be linked to the negative Southern Annular Mode, reduces the temperature in the southwestern part of southern Africa. Also, during the analysis period, El Ni?o was associated with temperature increases over the central parts of southern Africa;while the positive Indian Ocean dipole was linked to a temperature increase over the northeastern, northwestern, and southwestern parts of southern Africa.

Comparative utility of vestibular function tests in patients with peripheral and central vestibular dysfunction

Background: Bithermal caloric irrigation, video head impulse test(vHIT), and rotational testing are commonly used to assess peripheral vestibular function, but the relative clinical utility of each test in differentiating patients with peripheral vestibulopathy is ***: To determine whether(1) the combination of two or more vestibular tests enhances diagnostic utility over a single test;(2) abnormal test results on vestibular tests correlate with one ***: Retrospective analysis of data collected from multidisciplinary vestibular clinics at two academic medical centers from 2016 to ***: 150 patients(54.10 ± 15.09 years, 88 females) were included. No individual test was significantly better at predicting the presence of peripheral vestibular damage(p > 0.05). vHIT test results improved significantly when combined with either the caloric test(p = 0.007) or rotary chair test(p = 0.039). Caloric and rotational testing had high sensitivity(74.65% and 76.06%, respectively) and specificity(83.54% and 78.48%, respectively). vHIT demonstrated excellent specificity(89.87%) but poor sensitivity(47.89%). Caloric, vHIT, and rotary chair tests results did not correlate with one another(p > 0.05).Conclusions: Vestibular function tests have comparable diagnostic utility, yet each offers unique advantages. Caloric and rotational testing may be best suited for screening peripheral damage and vHIT may function ideally as a confirmatory test.

Title: Integrating Consistent Individualized Carbohydrate-Controlled Anti- Inflammatory Nutritional Plan (C-ICAN) in the Management of Prader-Willi Syndrome: A Case Report. Prader–Willi syndrome (PWS) is a rare genetic disorder caused by a loss of function of specific genes on chromosome 15. Patients with this disease present unique challenges in management, particularly regarding obesity and nutritional regulation as the disease symptoms change depending on the age of the patient and the phase of the disease. These challenges pose critical stressors to caregivers and their families. We present a case report of a 5-year-old Caucasian male diagnosed with PWS, exhibiting failure to thrive and uncontrolled weight gain. His caregiver was his elderly grandmother who, by her own admission, was ill-equipped to deal with the patient’s physical symptoms and his behavior in response to dietary restrictions. Through a multidisciplinary approach involving medical nutrition therapy (MNT) involving the implementation of a Consistent Individualized Carbohydrate-Controlled Anti-Inflammatory Nutritional plan (C-ICAN), growth hormone supplementation, and behavioral interventions patient markedly improved physically and emotionally.

The Performance of Small Diameter Aluminum Light Support Structures Containing Handholes under Cyclic Fatigue

引用

Open Journal of Civil Engineering 2024年第2期14卷 196-213页

作者： cameron R. Rusnak Aya Al-Hamami Craig C. Menzemer Department of Science Technology and Mathematics Lincoln University of Missouri Jefferson Missouri USA Auburn Science and Engineering Center Department of Civil Engineering The University of Akron Akron Ohio USA

Aluminum light poles play a pivotal role in modern infrastructure, ensuring proper illumination along highways and in populated areas during nighttime. These poles typically feature handholes near their bases, providing access to electrical wiring for installation and maintenance. While essential for functionality, these handholes introduce a vulnerability to the overall structure, making them a potential failure point. Although prior research and analyses on aluminum light poles have been conducted, the behavior of smaller diameter poles containing handholes remains unexplored. Recognizing this need, a research team at the University of Akron undertook a comprehensive experimental program involving aluminum light poles with handholes containing welded inserts in order to gain a better understanding of their fatigue life, mechanical behavior, and failure mechanisms. The research involved testing seven large-scale aluminum light poles each 8-inch diameter, with two separate handholes. These handholes included a reinforcement that was welded to the poles. Finite Element Analysis (FEA), statistical analysis, and comparison analysis with their large counterparts (10-inch diameter) were used to augment the experimental results. The results revealed two distinct failure modes: progressive crack propagation leading to ultimate failure, and rupture of the pole near the weld initiation/termination site around the handhole. The comparison analysis indicated that the 8-inch diameter specimens exhibited an average fatigue life exceeding that of their 10-inch counterparts by an average of 30.7%. The experimental results were plotted alongside the fatigue detail classifications outlined in the Aluminum Design Manual (ADM), enhancing understanding of the fatigue detail category of the respective poles/handholes.

中国历史官员量化数据库——(清)缙绅录(CGED-Q JSL)中文官的纵向关联记录揭示了19世纪清代文官整体的职业动态。定量分析的结果表明,清代官僚系统的总体情况就像一个当代的大型组织,文官离职率在任职的第一年内很高,然后下降,之后趋于稳定。19世纪下半叶,官员的离职率整体下降,但于清末十年中上升。官员离职率下降导致拥有功名的候缺待补官员群体谋求仕途和进一步晋升的机会不断减少。同时,异途官员的人数不断增加,加剧了官场竞争。不同类别、品级官员的职业动态在不同历史时期的变化趋势差异较大,尤其是高品级官员的离职率对清代后期的官场平衡具有深刻影响。清代文官的职业动态一方面揭示了清代文官组织人口学的基本特征,另一方面也为解释清代特定官员群体或特定时期的官员个案研究提供了重要参考。
