Background: Nursing care in the recovery room is oriented to take into account the patient’s condition after surgery intervention with its main purpose of providing direct and continuous patient observation in emergence from general or regional anesthesia. In the absence of professional assistance, patients can develop complications that can lead them into shock or death. This study aims to understand the place of nurses in guiding nursing care in recovery room in two hospitals of Gitega Province by assessing the nurse’s knowledge and attitudes for the promotion of quality nursing care for post-operative patients. Methods: A cross sectional study design was used to assess the practice of nurses in managing nursing care in the recovery room in these two hospitals. A purposive sampling method was used to select the 82 nurses working in the recovery room for these two hospitals and Alain Bouchard’s formula was used to calculate the sample size. Data were collected using a self-report method involving questionnaire completion with five components addressing participants identifications, factors related to the work organization, factors related to the work environment, factors related to healthcare system, and nursing interventions in recovery room. Results: Findings revealed a significant lack of knowledge among the participants and their attitudes were slightly poor as for most of the variables of factors related to healthcare system as their score was less than 50% and their knowledge for nursing interventions was also poor as most of variable scores were less than 25%. Conclusions: The study findings were slightly poor as their scores were less than 50% in most of the variables;therefore, it was recommended that in-service training and workshops should be organized by these healthcare facilities for the purpose of empowering the nurse’s knowledge and practice. Moreover, these institutions should prov

Neuro-fuzzy and model-based motion control for mobile manipulator among dynamic obstacles

引用

Science in China(Series F) 2003年第1期46卷 14-30页

作者：魏武 jean bosco Mbede 黄心汉张毅 Department of Automation Tsinghua University Departement des Genies Industrie Universit de Yaound I Ecole Nationals Superieure Polytechnique Department of Control Science and Engineering Huazhong University of Science and Technology

This paper focuses on autonomous motion control of a nonholonomic platform with a robotic arm, which is called mobile manipulator. It serves in transportation of loads in imperfectly known industrial environments with unknown dynamic obstacles. A union of both procedures is used to solve the general problems of collision-free motion. The problem of collision-free motion for mobile manipulators has been approached from two directions, Planning and Reactive Control. The dynamic path planning can be used to solve the problem of locomotion of mobile platform, and reactive approaches can be employed to solve the motion planning of the arm. The execution can generate the commands for the servo-systems of the robot so as to follow a given nominal trajectory while reacting in real-time to unexpected events. The execution can be designed as an Adaptive Fuzzy Neural Controller. In real world systems, sensor-based motion control becomes essential to deal with model uncertainties and unexpected obstacles.

New Optimal Pivot Rule for the Simplex Algorithm

引用

Advances in Pure Mathematics 2016年第10期6卷 647-658页

作者： jean bosco Etoa Etoa Department of Economic and Management Sciences University of Yaounde II Soa Cameroon

The purpose of this paper is to introduce a new pivot rule of the simplex algorithm. The simplex algorithm first presented by George B. Dantzig, is a widely used method for solving a linear programming problem (LP). One of the important steps of the simplex algorithm is applying an appropriate pivot rule to select the basis-entering variable corresponding to the maximum reduced cost. Unfortunately, this pivot rule not only can lead to a critical cycling (solved by Bland’s rules), but does not improve efficiently the objective function. Our new pivot rule 1) solves the cycling problem in the original Dantzig’s simplex pivot rule, and 2) leads to an optimal improvement of the objective function at each iteration. The new pivot rule can lead to the optimal solution of LP with a lower number of iterations. In a maximization problem, Dantzig’s pivot rule selects a basis-entering variable corresponding to the most positive reduced cost;in some problems, it is well-known that Dantzig’s pivot rule, before reaching the optimal solution, may visit a large number of extreme points. Our goal is to improve the simplex algorithm so that the number of extreme points to visit is reduced;we propose an optimal improvement in the objective value per unit step of the basis-entering variable. In this paper, we propose a pivot rule that can reduce the number of such iterations over the Dantzig’s pivot rule and prevent cycling in the simplex algorithm. The idea is to have the maximum improvement in the objective value function: from the set of basis-entering variables with positive reduced cost, the efficient basis-entering variable corresponds to an optimal improvement of the objective function. Using computational complexity arguments and some examples, we prove that our optimal pivot rule is very effective and solves the cycling problem in LP. We test and compare the efficiency of this new pivot rule with Dantzig’s original pivot rule and the simplex algorithm in MATLAB environment.

Introduction: Aseptic procedures are undertaken by nurses in the general ward. The lack of nurse’s aseptic techniques in clinical setting result to patients or healthcare expositions to hospital-acquired infections which are most of the time caused by lack of knowledge or ignorance of implementing the principles of aseptic technique. This study aims to assess nurses’ knowledge and the possible barriers in the implementation of the principles of asepsis in healthcare setting. Methods: A cross-sectional study design was used to assess the nurses’ knowledge and the possible barriers for implementing principles of asepsis in healthcare setting among. The study was carried out at Clinique Van Norm (CVN), a free Methodist Church related institution located in the north District of Bujumbura city in Burundi, from October to November, 2021 among nurses who work within three services of the clinic (Gynecology and Obstetrics, Pediatric and Operating room). A convenience sampling method was used to invite all nurses (44) working in the 3 services of CVN to participate in our study. A self-report method involving questionnaire completion with three components addressing demographic data, participants’ knowledge and barriers to implement the principles of asepsis was used to collect data which were later on analyzed by SPSS version 21. Results: Research findings show a significant participant’s poor knowledge on principles of asepsis in the hospital as for almost variables used to assess their knowledge, they scored less than 50% except for the time of using sterile gloves in which most of the participants (71.4%) said that they do use sterile gloves when indwelling urinary catheters, labor and delivery, newborn care, wound dressing or suturing, or any time handling aseptic equipment, inserting nasogastric feeding tube... In addition, participants argued that they know the principles of asepsis (57.1%), however, only 14.3% of them were able to list at least 5 of the principles o

Open Journal of Geology 2019年第13期9卷 1069-1083页

作者： jean de Dieu ndikumana Anthony Temidayo Bolarinwa Gabriel Oladapo Adeyemi Institute of Life and Earth Sciences Pan African University Ibadan Nigeria Department of Geology University of Ibadan Ibadan Nigeria Department of Mining Regulation and Inspection Rwanda Mines Petroleum and Gas Board (RMB) Kigali Rwanda

The aim of this work was to study the petrography, geochemistry of the pegmatites, their relationship to the mineralisation in Gitarama and Gatumba areas, and current processes that occurred after the primary emplaced neoproterozoic rare element pegmatites. Previous works on pegmatites were geochemistry and geological maps which are not enough for focused exploration and mine planning. Therefore, geological, petrographic, geochemical studies of neoproterozoic rare element pegmatites of Gatumba and Gitarama areas in relation to their mineralisation were carried out. The samples were analysed for mineral assemblages by petrographic light microscope;major elements by ICP AES;trace and rare earth elements by ICP MS. Petrographic studies revealed the mineral assemblages included quartz, microcline, biotite and major muscovites, which implied that there was the process of muscovitisation occurred after the primary emplacement of pegmatites. The results of geochemical analysis revealed that the silica content (in wt%) ranges from 59.5 - 80.5 with an average of 67.13 (in wt%) for the weathered pegmatite in Gatumba area ,and high percentages of SiO2 (in wt%) range 73.9 - 75.0 with an average of 73.15 (in wt%) for fresh pegmatite in Gitarama area. The pegmatites from Gatumba area were altered and much enriched in Rb (227 - 3460 ppm), Cs (2.59 - 24.7 ppm), Ta (2.6 - 268 ppm), Li (40 - 9224 ppm), W (240 - 10,000 ppm), Nb (13 - 517 ppm), Sn (24 - 8870 ppm). Their enrichment is commonly used as a marker of a magmatic-hydrothermal alteration. Conversely, the pegmatites from Gitarama area showed the low to moderate concentrations in Rb (321 - 337 ppm), Cs (5.47 - 5.62 ppm), Ta (1.3 - 1.6 ppm), Li (~20 ppm), W (5540 - 6410 ppm), Nb (3.9 - 4.3 ppm), Sn (28 - 44 ppm). The variation plot of ratios: Al2O3/(Na2O + K2O) versus Al2O3/(CaO + Na2O + K2O) for the pegmatites from study areas are higher than one (A/NK vs. A/CNK > 1) indicating peraluminous, the other samples of pegmatites indic

Background: Gestational Diabetes Mellitus (GDM) is the most common complication of pregnancy that causes chronic hypertension, increased rate of cesarean delivery, fetal mortality and morbidity. Therefore, early diagnosis of GDM is vital to reduce maternal and fetal morbidity. Moreover, it can circumvent or procrastinate the onset of type 2 diabetes. Objectives: The main objective of this study was to determine the prevalence of GDM in pregnant women attending Kimironko, Kicukiro and Muhima Health Centres. The specific objectives were to determine the blood glucose during the second trimester in pregnant women aged between 21 and 45 years, to find out the frequencies of pregnant women presenting with GDM according to age and to assess some promising risk factors associated with GDM. Methods: A cross-sectional study was carried out at Kimironko, Kicukiro and Muhima Health centers using a sample size of 96 pregnant women. Blood glucose levels were measured using glucose oxidase method with a glucometer. Data were analyzed by using Microsoft Office Excel and SPSS version 20. Results: Out of 96 pregnant women who participated in the study, 8.3% were found to have GDM with the mean ± 2SD of 194.12 ± 25.53 mg/dl of their blood glucose results (Mean ± 2SD: A 95% level of confidence Intervals). The highest proportion of GDM was revealed in pregnant women aged between 26 - 30 years, representing a frequency of 5.2% whereas 2.1% of GDM was reflected in women aged between 21 - 25 years. The lowest proportion of GDM fell in age group of 31 - 35 years contributing to 1% of the total GDM. There were no cases of GDM in pregnant women in the 36 - 40 or 41 - 45 age groups. The mean ± 2SD of participant’s age groups was 27.12 ± 5.01 years. In addition, while obesity did not show to be associated with GDM, age and family history were found to be risk factors of GDM. Conclusion: The findings of this study revealed that the prevalence of GDM was 8.3% and the most affected pregnant women

邻苯二甲酸酯（Phthalates,PAEs）类化合物,主要用于增塑剂中,以提高各种日常用品的弹性、柔软性和耐久性,其中,邻苯二甲酸二（2-乙基己）酯（di-（2-ethylhexyl）-phthalate,DEHP）使用最为广泛。DEHP主要用于制造聚氯乙烯（Polyvinyl Chloride,PVC）相关产品,另外,它还用于制造鞋履、浴帘、医疗器械、衣服、床上用品、胶凝剂、产品包装、建筑材料、粘合剂和儿童玩具。虽然DEHP在生产生活中用途十分广泛,但DEHP也会对产生健康不利影响,这是因为DEHP其实是一种内分泌干扰激素,它会干扰生物的正常生理功能。据报道,在人类和其他动物中,DEHP均会引起机体发生生殖、呼吸或者发育缺陷,并且水解和光解都无法从已污染的环境中去除DEHP,因此生物降解成为消除DEHP污染和修复环境最为有效的方法。本研究的目的是分离、鉴定DEHP高效降解菌株,该菌株能将DEHP作为唯一碳源。我们从武汉市南湖收集了土壤样品和水样,经过处理分离得到L1-W菌株,通过形态学、生理学、16S rDNA测序等方法鉴定出L1-W为苍白杆菌属。当温度为30℃,pH为6.0,DEHP浓度为400mg/L时,L1-W降解DEHP的效率最高。另外,L1-W具有很强的耐盐能力,在盐浓度为10%依旧能发挥降解效力,这使L1-W成为修复盐环境的理想选择之一,且无需额外的淡化成本。此外,L1-W能降解多种邻苯二甲酸酯,例如邻苯二甲酸苄基酯、邻苯二甲酸二丁酯、邻苯二甲酸二甲酯、邻苯二甲酸二辛酯和邻苯二甲酸二乙酯,DEHP均能将它们作为唯一碳源。在上述最佳降解条件下,DEHP初始浓度为200mg/L时,L1-W降解DEHP的动力学遵循一阶方程,半衰期为11.3小时,此时98.7%的DEHP被降解。根据这些发现,菌株Ochrobactrum antropi L1-W可用于从污染环境中去除DEHP,因而修复环境。
