Inflection point identifying of weld seam based on force sensing in tele-teaching

Weld seam inflection points are inevitable in tele-teaching process on many welding occasions. The inflection points identified accurately is one of the prerequisites of ensuring tele-teaching precision. On the basis of the inflection point characters, the concept of inflection point direction coefficient is proposed, the human-simulation intelligent control model of inflection point is established. The algorithms above, the inflection point identifying of box workpiece can be well performed. The experimental results show that the identifying average error of inflection point can be reduced to less than O. 5 mm by using optimal treatment of robot off-line programming system. The identifying control can automatically identify weld seam inflection points which can meet tele-teaching requirements.

A Graded and Individualized Teaching and Learning method

Taking the programming course as an example,a comprehensive solution for individualized and precise teaching has been proposed.Firstly,graded teaching strategy is performed.The students are divided into three groups according to their base of learning and the degree of acceptance of knowledge.Designed teaching resources are provided for the teaching mode of low starting points and high landing points.Secondly,a process evaluation method combining online and offline has been proposed.An“evaluation-feedback-improvement”mechanism based on the analysis of students’learning data has been adopted.The practice in Harbin Institute of Technology has shown that the proposed method can not only help students achieve individualized learning goals,but also help teachers achieve precise teaching.

Towards an Antimicrobial Stewardship Program in a Young Tertiary Hospital in Southern Nigeria: A Point Prevalence Survey of Antimicrobial Usage

Background: Antimicrobial resistance (AMR) is one of the top 10 global public health threats facing humanity and this burden is borne largely by low and middle-income countries. As part of efforts to combat AMR, the World Health Organization has identified Antimicrobial Stewardship as one of the strategic objectives of its global action plan on antimicrobial resistance. This survey aimed to observe antimicrobial prescribing and usage patterns in the Rivers State University Teaching Hospital with the purpose of identifying gaps to inform the specific antimicrobial stewardship interventions necessary to address our specific needs. Methodology: A point prevalence survey was conducted using the protocol and web-based automated data management system designed by the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance, University of Antwerp, Belgium, in November 2021. Results: A total of 69 adult medical and surgical patients were surveyed;27 males and 18 females. Antimicrobial prevalence was 65.2%. Third generation cephalosporins (24.4%;33.3%), fluoroquinolones (17.8%;22.2%) and imidazole derivatives (20%;36.1%) were most prescribed on the medical and surgical wards. Antimicrobial guidelines were completely unavailable, most antimicrobials (93.8%) were prescribed empirically and 64.4% of these remained empirical after 72 hours of commencement. Conclusion: Antimicrobial stewardship interventions are necessary to minimize sub-optimal antimicrobial prescribing practices in our facility. Most critical are education on appropriate use of antimicrobials, support for development of antimicrobial guidelines, diagnostic stewardship, and the drive for improved use of the laboratory to guide antimicrobial prescriptions. The antimicrobial stewardship committee and team must drive this, having the requisite support from the management and prescribers, with the primary outcomes being reduced antimicrobial prevalence and improved antimicrobial prescription patterns.

Renal Failure of Lithiasis Origin: Frequency and Management in the Nephrology and Haemodialysis Department of the Point G University Hospital in Mali

Background: The term urinary lithiasis (UL) from the Greek “lithos” refers to the disease characterised by the result of abnormal precipitation of normal constituents of the urine within the urinary tract. The aim of this work was to determine the frequency of obstructive renal failure (ORF) of lithiasis origin and to describe the therapeutic indications. Methods: This was a retrospective prospective study in patients hospitalised in the nephrology department of Point G University Hospital for ORF of lithiasis origin over a 26-month period from 1 January 2018 to 1 February 2020 inclusive. Results: Among 1898 hospitalized patients, 32 met the inclusion criteria, i.e. a frequency of 1.7%. The male sex was 68.75% with a sex ratio of 2.2. The mean age was 48.38 ± 13.423 years with extremes of 20 and 65 years. Dysuria and urinary bilharzia were the main uro-nephrological antecedents, accounting for 25% of the cases each. Pain syndrome was the main functional sign, accounting for 100%. Ultrasound of the urinary tract (n = 28) showed stones in 92.85%. These stones were bilateral in 22.22% of cases. The dilatation was pyelocalic in 14 cases (51.8%). The uroscanner showed a pyelic location of the stones in both kidneys;42.1% on the right and 33.3% on the left. Hydronephrosis was the most common dilatation: 37.8% on the right and 29.7% on the left. Renal lithiasis was complicated by acute kidney injury (ARI) in 17 cases (53.1%) versus 15 cases (46.9%) of chronic kidney disease (CKD). Urethral catheter was the means of drainage in 24 (75%) followed by nephrostomy in 8 cases (25%). Nephrolithotomy accounted for 9.4% of cases. The case fatality rate was 28.12% (9 cases). Deaths occurred in the context of uraemic coma 6 cases and cardiorespiratory arrest 3 cases. Conclusions: The management of urinary lithiasis complicated by renal failure calls for the correction of hydrolytic disorders, drainage of the excretory tract and treatment of the stone, of which percutaneous nephrolithotomy seems to be the modality of choice.

物理化学实验教学细节探讨——凝固点降低法测定物质摩尔质量

“凝固点降低法测定物质摩尔质量”是物理化学实验中的经典实验之一。鉴于现有的物理化学实验教材和文献对凝固点测定部分内容描述不够细致,如过冷现象产生的原因解释不够全面、深入;纯溶剂近似凝固点测定需要观察“当有固体析出时”,析出的固体优先在玻璃管的何处出现?析出的固体呈现什么形貌?这些问题的存在,会使学生操作实验时产生困扰。本文针对上述问题,通过实验创新对溶剂凝固过程进行全程拍摄,分析固体析出的具体位置、形貌,得出学生实验操作时,应观察固体从玻璃管底部优先析出絮状物为宜;通过凝固点降低法,观察溶剂固体析出的细节,计算、分析溶质的分子量,得到了可靠的实验结果。本文对凝固点降低法操作细节深入研究与探讨,可以有效地避免或消除实验操作中出现的问题,大大提高学生实验效果。
