A livestock production system is a group of farm operations with approximately the same characteristics of climatic conditions and farming practices. Farm type identification helps to identify area specific problems and give proper technological intervention to address the problems. Therefore, this study was initiated to identify the livestock production systems and their constraints in West Arsi Zone. Both Primary and secondary data collection method was used to collect data. Secondary data was collected from Zone and concerned district offices using checklists. In addition to this, published and unpublished materials are also used as sources of secondary data. Multi-stage sampling technique was employed to select representative districts, kebeles and sample households. Focus group discussion (FGD), key informant interview and household direct interviews by using semi-structured questionnaires are used to collect primary data. A total of 264 sample households are selected to collect primary data. Descriptive statistics was used to analyze the collected data using STATA version 14. The study result identified livestock production system was classified mixed rainfall sufficient (MRS) which cattle, equine and sheep production system dominantly practiced and mixed rainfall deficit (MRD) which goat, beekeeping and backyard poultry production system majorly practiced. The major livestock production constraints like lack of access to credit services, shortage of improved breed, lack of livestock technologies, shortage of feed, disease, and climate change were identified and the possible policy implications were suggested to address the problems.
牲畜生产系统是一组具有大致相同气候条件和耕作方法特征的农场操作。确定农场类型有助于确定特定地区的问题,并提供适当的技术干预来解决问题。因此,本研究旨在确定西阿尔西地区的畜牧生产系统及其制约因素。数据收集采用了一手和二次资料收集方法。从分区及有关分区办事处收集辅助资料,并使用核对表。除此之外,已发表和未发表的材料也被用作辅助数据的来源。采用多阶段抽样方法,选取有代表性的地区、乡镇和样本住户。采用焦点小组讨论(FGD)、关键信息提供者访谈和家庭直接访谈,采用半结构化问卷收集原始数据。选取264个样本家庭收集原始数据。使用STATA version 14对收集到的数据进行描述性统计分析。研究结果表明,畜禽生产系统以牛、马、羊生产系统为主,以混合降雨充足(MRS)为主;以山羊、养蜂和后院家禽生产系统为主,以混合降雨不足(MRD)为主。确定了牲畜生产的主要制约因素,如缺乏信贷服务、缺乏改良品种、缺乏畜牧技术、饲料短缺、疾病和气候变化,并就解决这些问题可能产生的政策影响提出了建议。

It is known that the progressive deterioration of the immune system in the human immunodeficiency syndrome (AIDS), either cellular or humoral level and the obligated role of exchange of the respiratory system with the external environment, makes the incidence of inflammatory, tumoral, and infectious lung processes high in patients infected with the human immunodeficiency virus (HIV). There are several microorganisms that can cause cavitated lung lesions in a HIV patient as Pneumocystis carinii, Mycobacterium tuberculosis or Staphylococcus aureus, among others. Rhodoccoccus equi (R. Equi) is, predominantly, an opportunistic pathogen who can also cause disease in humans, especially in immunocompromised patients. This report describe a case of Rhodococcus equi lung infection in a HIV patient, which highlights the importance of the therapheutic adherence and the epidemiological enviroment in this kind of patients.
众所周知,人类免疫缺陷综合征(AIDS)患者免疫系统的进行性恶化,无论是细胞水平还是体液水平,以及呼吸系统与外界环境交换的义务作用,使得感染人类免疫缺陷病毒(HIV)的患者炎症、肿瘤和感染性肺过程的发生率很高。有几种微生物可引起艾滋病毒患者的肺空洞性病变,如卡氏肺囊虫、结核分枝杆菌或金黄色葡萄球菌等。马红球菌(r.a equi)主要是一种机会性病原体,也可引起人类疾病,特别是免疫功能低下的患者。本报告描述1例HIV患者肺部感染马红球菌的病例,突出了这类患者治疗依从性和流行病学环境的重要性。

Increasing the protection efficiency of helmets is counted as the biggest challenge in ice hockey. The main objective of this study is twofold: first to understand the effect of fitting on the protection capability of ice hockey helmets, and second to determine a possible optimal fit with respect to minimum head accelerations. A purpose-built monorail drop tower was utilized to perform front and front boss impacts at a velocity of 4.47m/s on a custom headform outfitted with a commercial helmet (CCM Resistance) with no gap (tight fit), 2mm (regular fit), and 5 mm gaps (loose fit). It was observed that while in both impacts linear accelerations were lower for the regular fit model, the loose fit model predicted the lowest angular accelerations. A loosely-fitted helmet provides non-deterministic shifting upon impact which generally leads to a wider standard deviation of linear and angular accelerations. The results indicated that in front impacts while introducing a gap reduced the risk of focal injuries, only the loose fit model suggested lower risks of concussive injuries. However, the regular and loose fit models showed better protection against focal and concussive injuries in the front boss impacts, respectively.
提高头盔的防护效率被认为是冰球运动中最大的挑战。本研究的主要目的有两个:第一,了解冰球头盔的配合对保护能力的影响,第二,确定一个可能的最佳配合,相对于最小的头部加速度。一个专门建造的单轨跌落塔被用来在一个定制的头型上以4.47米/秒的速度进行前凸台和前凸台的撞击,头型上装有商用头盔(CCM Resistance),无间隙(紧密配合)、2mm(常规配合)和5mm间隙(宽松配合)。观察到,在两种碰撞中,规则拟合模型的线性加速度都较低,而松散拟合模型预测的角加速度最低。一个松散的头盔在碰撞时提供了不确定的位移,这通常会导致更大的线性和角加速度的标准偏差。结果表明,引入间隙的正面撞击降低了局灶性损伤的风险,只有宽松配合模型降低了脑震荡的风险。然而,常规和宽松的模型分别对前凸台撞击的局灶性和震荡性损伤具有更好的保护作用。

Noninvasive ventilator connects a one-way circuit with leak and delivers inspired gas via the upper airway tract. A heated humidifier don’t have to connect to contain heat and moisture exchange humidity in the upper airway functions. However, there are many case connecting a heated humidifier to be inadequate humidity in the upper airway. The purpose of this study was to clarify the influence of absolute humidity on leak and inspiratory positive airway pressure during noninvasive positive pressure ventilation. We connected respiratory machine, a heated humidifier and a model lung via two type circuits. One circuit was a single-limb breathing with an exhalation port and another was two- way circuits to distinguish the inspiratory from the expiratory via Y-piece. Two heated humidifiers were included in both inspiratory and expiratory circuits to simulate the physical lung. Relative humidity, temperature and flow rate were measured for 30 minutes. Absolute humidity was calculated using the Teten’s equation and a gas state equation with relative humidity and temperature. In results, flow rate increased and absolute humidity decreased, when leak volume increased. We presumed that warmer humidified gas was discharged through the leak port with increasing flow rate to compensate leak. However, absolute humidity slightly was not associated with higher inspiratory positive airway pressure at the steady leak. We supposed that expiratory gas was not capable to discharge due to increasing flow rate and might be accumulated into the mask. The expired gas temperature accumulated in the mask might affect the inspired absolute humidity. Consequently, we are desirable to measure the inspired gas temperature and absolute humidity. In conclusion, absolute humidity would depend on leak during noninvasive positive pressure ventilation.
无创呼吸机连接有泄漏的单向回路,通过上呼吸道输送吸入气体。加热加湿器不需要连接包含热和湿气交换的上呼吸道湿度功能。然而,在许多情况下,连接加热加湿器会导致上呼吸道湿度不足。本研究旨在探讨无创正压通气过程中绝对湿度对气道漏气和吸气正压的影响。我们通过两种电路连接呼吸机、加热加湿器和模型肺。一种是带呼气口的单肢呼吸回路,另一种是通过y形片区分吸气和呼气的双向回路。两个加热加湿器包括在吸气和呼气回路模拟物理肺。测量相对湿度、温度、流速30分钟。绝对湿度的计算采用Teten方程和气体状态方程与相对湿度和温度。结果表明,随着泄漏量的增大,流量增大,绝对湿度减小。我们假定暖湿化气体通过泄漏口以增大流量排放以补偿泄漏。然而,在稳定泄漏时,绝对湿度与较高的吸气气道正压无关。我们推测呼气气体由于流速增加而无法排出,可能积聚在口罩内。口罩内累积的过期气体温度可能会影响吸入的绝对湿度。因此,我们需要测量吸入气体的温度和绝对湿度。总之,绝对湿度取决于无创正压通气时的泄漏。

Introduction. There is some data of the short-chain fatty acids (SCFA) participation in cancerogenesis. The cervical cancer is an “ideal” model for determining the molecular mechanisms underlying the development of cancer. The aim of study was to estimate the influence of propionate on the spectrum of SCFA in cervical cells during dis- and neoplastic transformation. Materials and methods of research. Materials of the study - cervical biopsy verified morphologically. Study groups: IA - the focus of the pretumor lesion of cervix; IB - paradisplastic cells; IIA - locus of cervical cancer; IIB - paraneoplastic cells. The spectrum of fatty acids was analyzed before, after 24 hours incubation with 50 μmol/l propionic acid by the gas chromatography method. Methods of nonparametric statistics the Mann-Whitney test were used. Differences were considered statistically significant at p<0.05. Results of the study. The incubation of cervical cancer cells with propionate leads to an increase the level of propionate and butyrate. The incubation of "precancer", paraneoplastic and paradisplastic cells leads to an increase the levels of isobutyric, valeric and caproic acids against the background of a significant drop in the concentration of propionate and butyrate. Сonclusion. It can be concluded that the effect of propionate on the metabolism of fatty acids in the cervical epithelium of the studied samples is multidirectional and depends on the cell type. The dates indicate the modifications of SCFA in the cervical carcinogenesis.

Dust is a common pollutant of the air we breath. If dust particles are inhaled and deposited in human airways, they can cause a variety of respiratory disorders. The inhaled dust particles motion in human airways goes along with the airflow. The transport process can be considered as a two-phase flow of a gas phase and a particle phase. In this study, we investigated the airflow and dust particles transport and deposition in human tracheobronchial airways using computational fluid dynamics (CFD) techniques. A steady simulation was performed in asymmetric tracheobronchial airway mode consisting of 19 outlets to observe the characteristics of airflow fields. The discrete phase model (DPM) was employed to predict the particle trajectories and deposition in the airway model. Deposition resulted from inertial impaction and gravitational sedimentation was considered. In the simulation, the airflow characteristics differences in the right and left bronchial trees were observed. The influence of secondary flow on dust particles motion was great. More dust particles were deposited in the right bronchial tree than in the left. The deposition fraction of dust particles in human tracheobronchial airways was high. This study can provide awareness on deposition of dust particles passing beyond the larynx and enhance prevention of their entry into the respiratory system. It can also contribute a convenient way on the location of deposition of particles of a given type in human respiratory tract to be used for respiratory disease preventions.
灰尘是我们呼吸的空气中常见的污染物。如果灰尘颗粒被吸入并沉积在人体的呼吸道中,它们会引起各种呼吸系统疾病。吸入的粉尘颗粒在人体气道中随气流运动。输运过程可以看作是气相和颗粒相的两相流动。本研究采用计算流体动力学(CFD)技术研究了人体气管支气管内气流和粉尘颗粒的传输和沉积。在有19个出口的非对称气管-支气管气道模式下进行稳态模拟,观察气流场特性。采用离散相模型(DPM)预测颗粒在气道模型中的运动轨迹和沉积。考虑了惯性碰撞和重力沉降引起的沉积。在模拟中,观察了左右支气管树气流特性的差异。二次流对粉尘颗粒运动的影响较大。右支气管树比左支气管树沉积更多的尘粒。粉尘颗粒在人气管支气管的沉积比例较高。这项研究可以提供对通过喉部的尘埃颗粒沉积的认识,并加强对其进入呼吸系统的预防。它还可以提供一种方便的方法来确定特定类型的颗粒在人类呼吸道中的沉积位置,用于呼吸道疾病的预防。

Introduction: Malnutrition is one of the major nutritional problems in which the physical function of an individual is impaired to the point which cannot longer maintain adequate body performance process such as growth, physical work and resisting and recovery from the disease. Malnutrition usually stems from low economic situation, poor personal and environmental hygiene and ignorance are contributed to magnitude of high incidence of acute problem of malnutrition. Recent studies found that the center of the problem is the backward socio-economic development of the country which in turn results in one of the lowest standard of living, low level of social service, poor environmental conditions. In this respect it no disheartening to the not that the state of the health service in Ethiopia is low even when compared to the Sub-Saharan Africa countries. Objective: To assess magnitude of malnutrition and associated factors among pregnancy and lactating mother in Mi’esso health center, Mi’esso Woreda, Oromia Region, Ethiopia. Methods: Institutional based cross-sectional study was employed. The study was conducted from February 1 to May 30, 2017 among pregnancy and lactating in Mi’esso Woreda. A total of 304 sample was selected by systematic random sampling from the list of Clients, with different socio-demographic and the collected data was analyses by using computer with the total budget of 4846.9 Ethiopian birr. Results: The nutritional status of pregnancy and lactating mother based on their weight and height the BMI of the respondents indicates overweight accounts 12.6%, underweight 30.3%, and majority of the pregnancy and lactating mother accounts for 57.2% were normal nutritional level. The weight and height/length of the pregnancy and lactating mother included in the study were between 1.56 m to 1.78 m and weight 53 kg to 84 kg. From multiple logistic regression analysis family income (AOR=2.056, 95%CI=1.051-4.023) and age of women (AOR=2.169 (1.015-4.634)) were significantly associated with the nutritional status of the study participants. Recommendation: Facilitate rural-urban community’s access to information on nutrition like feeding practice sanitation, health and development program during pregnancy and lactation and efforts to expand awareness of women education using selected dietary during pregnancy and lactation.
简介:营养不良是一种主要的营养问题,在这种情况下,个人的身体功能受损,不能再维持足够的身体机能过程,如生长、体力劳动、抵抗和从疾病中恢复。营养不良通常源于经济状况不佳,个人和环境卫生状况不佳以及无知,这些都是造成急性营养不良问题发生率高的原因。最近的研究发现,问题的核心是国家落后的社会经济发展,这反过来又导致了生活水平最低,社会服务水平低,环境条件差。在这方面,即使与撒哈拉以南非洲国家相比,埃塞俄比亚的保健服务状况也很低,这一点并不令人沮丧。目的:评估埃塞俄比亚奥罗米亚地区米埃索沃勒达米埃索保健中心孕妇和哺乳期母亲营养不良程度及其相关因素。方法:采用基于机构的横断面研究。该研究于2017年2月1日至5月30日在米埃索沃尔达的孕妇和哺乳期妇女中进行。采用系统随机抽样的方法,从不同社会人口统计的客户名单中抽取304个样本,并利用计算机对收集到的数据进行分析,总预算为4846.9埃塞比尔。结果:根据受访孕妇的体重和身高,BMI指数显示超重占12.6%,体重不足占30.3%,多数孕妇营养水平正常占57.2%。研究中孕妇和哺乳期母亲的体重和身高/长度在1.56米至1.78米之间,体重在53公斤至84公斤之间。多元logistic回归分析显示,家庭收入(AOR=2.056, 95%CI=1.051 ~ 4.023)和女性年龄(AOR=2.169(1.015 ~ 4.634)与研究参与者的营养状况显著相关。建议:促进城乡社区在怀孕和哺乳期间获得营养方面的信息,如喂养做法、卫生、保健和发展方案,并努力扩大对在怀孕和哺乳期间使用选定饮食的妇女教育的认识。

Malnutrition usually stems from low economic situation, poor personal and environmental hygiene and ignorance are contributed to magnitude of high incidence of acute problem of malnutrition. Recent studies found that the center of the problem is the backward socio-economic development of the country which in turn results in one of the lowest standard of living, low level of social service, poor environmental conditions. In this respect it no disheartening to the not that the state of the health service in Ethiopia is low even when compared to the Sub-Saharan Africa countries. Objective: To assess magnitude of malnutrition and associated factors among pregnancy and lactating mother in Mi’esso health center, Mi’esso Woreda, Oromia Region, Ethiopia. Methods: Institutional based cross-sectional study was employed. The study was conducted from February 1 to May 30, 2017 among pregnancy and lactating in Mi’esso Woreda. A total of 304 sample was selected by systematic random sampling from the list of Clients, with different socio-demographic and the collected data was analyses by using computer with the total budget of 4846.9 Ethiopian birr. Results: The nutritional status of pregnancy and lactating mother based on their weight and height the BMI of the respondents indicates overweight accounts 12.6%, underweight 30.3%, and majority of the pregnancy and lactating mother accounts for 57.2% were normal nutritional level. The weight and height/length of the pregnancy and lactating mother included in the study were between 1.56 m to 1.78 m and weight 53 kg to 84 kg.
