Design of robust control system for any system requires model-driven approach. Therefore, it becomes imperative to develop a dynamic model suitable for controller design on safety operation of hydropower dam for power production in Kanji dam in Nigeria. Model for reservoir flow was developed in MATLAB environment using Fuzzy Based Autoregressive Moving Average Exogenous Input (FARMAX) model structure in this study. The data used for model development covered a period of ten years (2003-2013). It consists of water inflow (WI), water outflow (WO) and spillage (S). WI and S are input variables while WO was the output variable. The model obtained using the unsmoothed data with an outlier gave -14.115%, -0.302 and 610.317 for fit, R2 and RMSE, respectively. Unsmoothed data with no outlier gave -13.802%, -0.295 and 608.643 corresponding to fit, R2 and RMSE, respectively. The model obtained using the smoothed data in the presence of an outlier gave 80.533%, 0.962 and 104.113 for fit, R2 and RMSE, respectively. Smoothed data in the absence of outlier gave 81.533%, 0.962 and 99.637 for to fit, R2 and RMSE, respectively. FARMAX has the best fit value of 87.8774% when number of rules was equal to 3 with optima model order of 3 1 4 3. The model can serve as a decision support system in evaluating the optimal reservoir operation policies in real time.
任何系统的鲁棒控制系统的设计都需要模型驱动的方法。因此,为尼日利亚Kanji大坝发电开发一种适合于水电站大坝安全运行控制器设计的动态模型势在必行。本研究采用基于模糊的自回归移动平均外源输入(FARMAX)模型结构,在MATLAB环境下建立了水库流量模型。用于模型开发的数据涵盖了10年(2003-2013)。它由流入水(WI)、流出水(WO)和溢出水(S)组成,其中WI和S为输入变量,WO为输出变量。使用带有异常值的未平滑数据得到的模型的拟合、R2和RMSE分别为-14.115%、-0.302和610.317。没有异常值的未平滑数据的拟合、R2和RMSE分别为-13.802%、-0.295和608.643。使用存在异常值的平滑数据得到的模型的拟合、R2和RMSE分别为80.533%、0.962和104.113。在没有异常值的情况下,平滑数据的拟合、R2和RMSE分别为81.533%、0.962和99.637。当规则数为3时,FARMAX的最佳拟合值为87.8774%,最优模型阶数为3 1 4 3。该模型可作为实时评价水库最优调度策略的决策支持系统。

Illegal parking has been a topical issue in environmental planning and management, especially in the area of generating early warning systems for preparedness against space abuse. However, the concentration of research effort on accessibility in central business district with unjustified neglect of parking abuse impedes the search for analytical explanations and effective strategies to control spatial challenges. The study examined the types and nature of parking facilities and parking abuse. It also examined causes and effects of the abuse, as well as the response to abuse of the parking facilities in Ikeja Central Business District of Ikeja Local Government Area. Primary and secondary data were used for the study. Primary data were collected through in-depth interview with opinion leaders and questionnaires administered to 106 respondents randomly sampled in the core and periphery of the Central Business District of Ikeja. The data collected were analyzed using descriptive statistics such as frequency counts, percentage and chi-square. Secondary data used were map of the study area and images generated from Google earth. Results showed that there were two types of parking facilities; off-street (destination parking lot) and on-street parking facilities in the area. The nature of parking abuse was highly indiscriminate, and the prevailing type of parking facility abuse in the study area was unauthorized conversion of earmarked parking spaces to commercial trading spots. The effects of the parking abuse were mainly unavailability of parking space and traffic congestion, and the major perpetuators of the abuse were traders. The response of enforcement officials to indiscriminate parking was affirmed to be inefficient by 87.7% of the respondents. The study concluded that the abuse of parking facility was rampant in the study area.
非法停车一直是环境规划和管理中的一个热门问题,特别是在建立早期预警系统以防备空间滥用方面。然而,对中央商务区可达性的研究集中于对停车滥用的不合理忽视,阻碍了对控制空间挑战的分析解释和有效策略的探索。这项研究调查了停车设施的类型和性质以及滥用停车的情况。它还审查了滥用停车设施的原因和影响,以及对滥用Ikeja地方政府区的Ikeja中央商务区停车设施的反应。本研究采用了第一手资料和第二手资料。通过对意见领袖的深度访谈和对Ikeja中央商务区核心和外围随机抽取的106名受访者的问卷调查,收集了初步数据。使用频率计数、百分比和卡方等描述性统计方法对收集到的数据进行分析。次要资料是研究区域的地图和谷歌地球生成的图像。结果表明:城区停车设施有两种类型;该地区的非街道(目的地停车场)和街道停车设施。滥用泊车设施的性质是不分青红皂白的,而研究区内滥用泊车设施的主要类型是未经授权将指定泊车位改为商业交易地点。滥用泊车位的影响主要是泊车位不足和交通挤塞,而滥用泊车位的主要肇事者是商贩。87.7%的受访者认为执法人员对乱停车的反应效率低下。研究得出的结论是,在研究地区,滥用停车设施的现象十分猖獗。

Rapid urban growth in the federal capital of Nigeria in the last two decades has more effect on the development changes that characterized the cosmopolitan city. This has put enormous pressure on the built environment, where urban construction and transformation are taking place. The paper assessed urban growth and sustainable development of the built environment in Abuja. Its causes and consequences were investigated with respect to five {5} districts that make up the metropolis. The approach to this research is urban environmental sustainability in defining developmental change patterns for quality of the built environment research is presented, and a number of key performance indicators variables were examined. Seventy five (75) questionnaires were distributed to purposive respondents and Sixty- nine (69), accounting for 92% of the number of distributed questionnaires were retrieved and employed for data analysis. The research collected data using a uni-variated analysis on 31 rated likert of a five-point scale. Using descriptive and inferential statistics techniques, the sum weighted score (SWS), mean weighted score (MWS) and Relative Importance Index (RII) rating was obtained. Four major findings were discovered. Firstly, the predominantly building development skyline were for commercial services (MWS= 3.88). Secondly the factor of change in urban growth revolves around public building use and redevelopment of residential properties involving Increase property/Rental Value (MWS= 3.68). Thirdly the major determinants of urban growth were identified as social, economic and spatial political factors as demolition of satellite settlement (MWS=3.35) and lastly non adherence to managerial practices of building regulations enforcement and it implementation in construction. The noticeable consequences had been planning regulation/ provision (MWS=3.14) among others. The study recommended that property developer and stakeholder should adhere to designated master plan implementation and control measures while policy makers should focus more on meeting contemporary urban challenges such as rapid urbanization, balance between economic development and urban sustainability as well as environmental change.
在过去的二十年里,尼日利亚联邦首都的快速城市发展对国际大都市的发展变化产生了更大的影响。这给正在进行城市建设和改造的建筑环境带来了巨大的压力。本文评估了阿布贾的城市增长和建筑环境的可持续发展。对构成大都会的五个地区调查了其原因和后果。本研究的方法是城市环境可持续性在定义发展变化模式中的作用,对建筑环境质量进行研究,并对一些关键绩效指标变量进行了检验。向有目的的受访者发放了75份问卷,回收了69份,占发放问卷数量的92%,用于数据分析。该研究使用单变量分析收集了31个5分制李克特的数据。采用描述性统计和推理统计的方法,得到总加权评分(SWS)、平均加权评分(MWS)和相对重要性指数(RII)评分。研究发现了四个主要发现。首先,主要的建筑开发天际线用于商业服务(MWS= 3.88)。其次,城市增长的变化因素围绕公共建筑的使用和住宅物业的再开发,涉及物业/租金价值的增加(MWS= 3.68)。第三,城市增长的主要决定因素被确定为社会、经济和空间政治因素,如卫星住区的拆除(MWS=3.35),最后,不遵守建筑法规的执行和在建设中实施的管理实践。最明显的后果是规划条例/规定(MWS=3.14)。该研究建议,房地产开发商和利益相关者应遵守指定的总体规划实施和控制措施,而政策制定者应更多地关注应对当代城市挑战,如快速城市化、经济发展与城市可持续性之间的平衡以及环境变化。

Part of Ogbomoso Southwestern Nigeria was assessed using electrical resistivity method with a view to obtaining the subsurface geoelectric parameters (resistivities and thicknesses), categorizes the topsoil into different competence zones and evaluates the aquifer types, groundwater prospect and flow pattern. Fifty-four Vertical Electrical Sounding (VES) data were quantitatively interpreted using the partial curve matching technique to obtain the preliminary layer parameters which were further refined through 1-D forward modelling WinResist software package. The resulting final layer parameters were used to generate 2D geoelectric sections, isopach and isoresistivity maps and subsequently used to categorize the study area into different topsoil Competence, Aquifer types and Groundwater Potential zones. Static water levels of hand-dug wells in the area were used to generate the groundwater flow pattern. Four subsurface geoelectric layers were delineated. These were the topsoil, laterite, weathered/partly weathered layer (main aquifer) and fractured/fresh bedrock. The resistivities and thicknesses of the layers were 76-1858, 649-2021, 17-880 and 260-33385 Ωm and 0.4-4, 0.7-1.9 and 1.9-25.2 m respectively. The groundwater flow pattern in the area was NE-SW. The study concluded that incompetent to highly competent topsoil, weathered bedrock (main) aquifer unit/partly weathered/fractured bedrock aquifer and generally low groundwater potential with NE-SW flow direction underlay the study area.
采用电阻率法对尼日利亚西南部Ogbomoso部分地区进行了评价,获得了地下电参数(电阻率和厚度),将表土划分为不同的功能区,并对含水层类型、地下水远景和流型进行了评价。利用部分曲线拟合技术对54份垂直电测深(VES)数据进行定量解释,获得初步层位参数,并通过WinResist软件包进行一维正演模拟,进一步细化。得到的最终层参数用于生成二维地电剖面、等电阻率和等电阻率图,并随后用于将研究区域划分为不同的表土能力、含水层类型和地下水潜力带。利用该地区手挖井的静态水位生成地下水流型。圈定了4个地下地电层。表层土、红土、风化/部分风化层(主要含水层)和断裂/新鲜基岩。层的电阻率和厚度分别为76-1858、649-2021、17-880和260-33385 Ωm和0.4-4、0.7-1.9和1.9-25.2 m。该地区地下水流型为东北—西南。研究认为,研究区下部为不饱和-强饱和表土、风化基岩(主要)含水层单元/部分风化/裂隙基岩含水层,地下水潜力普遍较低,流向NE-SW。

The effects of dietary replacements of fish meal with soybean meal on growth performance, heamatology and serum biochemistry in juvenile Labeo cubie were evaluated. Four hundred and fifty (450) apparently healthy juvenile Laboe cubie were distributed into one of fifteen 1000 L tanks divided into five groups and fed any of diets A (0% soybean meal); B (30% soybean meal); C (40% soybean meal); D (45% soybean meal) and diet E (75% soybean meal) for 56 days. At set time points day 7, 14, 28 and day 56, five fish were randomly selected per tank for growth assessments, heamatology and serum biochemical evaluations. Growth performance indices decreased significantly (p < 0.05) along the gradient of soybean meal inclusion and the duration of feeding. The erythrocytes count increased significantly (p < 0.05) at day 14 in fish fed soybean meal diets and decreased significantly (p < 0.05) beginning at day 28 in fish fed soybean meal-based diets. The haematocrit of fish fed diets D and E were significantly (p < 0.05) lower at day 28 compared to day 56. There were no significant variations in haemoglobin concentration and the leucocytes counts (p > 0.05). The proteins, blood glucose and the transaminases increased significantly (p < 0.05) along gradient of dietary inclusion and duration of feeding in the first 28 days while creatinine kinase activity, blood urea nitrogen and uric acid concentration remained significantly elevated (p < 0.05) in fish fed the soybean meal-based diets. The results of the study show juvenile L. cubie may tolerate up to 40% dietary inclusion of soybean meal as replacement for fish meal.

The most widespread ailments in dogs are urinary tract infections (UTIs) caused by bacterial species. It is necessary to recognize the prevailing bacterial pathogens and their susceptibility to antimicrobial agents to effectively treat UTIs. The present study aimed to classify the bacterial organism that causes UTIs in dogs and their patterns of antimicrobial resistance. A total of 141 urine samples were collected from diseased dogs in Veterinary Clinical Complex LUVAS in Hisar, India. Culture, biochemical and sensitivity testing were performed for each of the urine samples based on standard method. Of the total 141 urine samples from dogs, 21 (14.9%) isolates were identified as Klebsiella spp. The isolates were found to be highly resistant to ampicillin (100%), penicillin G (100%), oxytetracycline (100%), enrofloxacin (85.7%), chloramphenicol (80.6%), ceftriaxone (76.2%) and cloxacillin (71.4%), while susceptibility was observed against gentamicin (100%), amikacin (100%) and neomycin (90.5%). In the current study, 19 out of 21 identified isolates were found to be multidrug-resistant. This study indicates that dogs in the study area are found to harbor highly resistant Klebsiella spp. Therefore, when deciding on the antibiotic regimen for UTIs cases, Vets should consider resistance profile of chosen antibacterial agents before usage in order to discourage dissemination of resistant organisms in the study area.
狗最普遍的疾病是由细菌引起的尿路感染(uti)。为了有效地治疗尿路感染,有必要了解流行的细菌病原体及其对抗菌药物的敏感性。本研究旨在对引起狗尿路感染的细菌有机体及其抗菌素耐药性模式进行分类。在印度希萨尔兽医临床综合中心LUVAS共收集了141份病犬尿液样本。按标准方法对各尿样进行培养、生化及敏感性试验。141份犬尿样中检出克雷伯菌21株(14.9%),对氨苄西林(100%)、青霉素G(100%)、土霉素(100%)、恩诺沙星(85.7%)、氯霉素(80.6%)、头孢曲松(76.2%)、氯西林(71.4%)高度耐药,对庆大霉素(100%)、阿米卡星(100%)、新霉素(90.5%)敏感。在目前的研究中,21个已确定的分离株中有19个被发现具有多重耐药。本研究表明,研究地区的狗携带高度耐药的克雷伯氏菌。因此,兽医在决定尿路感染病例的抗生素治疗方案时,应在使用前考虑所选抗生素的耐药情况,以阻止耐药菌在研究地区的传播。

Pineal region tumours may affect only a relatively small subset of neurosurgical patients, but they present enormous surgical challenge to the neurosurgeon due to their inaccessibly deep locations and compounded by the complex surrounding neurovascular structures. We present a case report of a patient who had combination chemoradiation without histological diagnosis but had complete tumour regression. Cyclical combination chemotherapy with cisplatin, etoposide and bleomycin and radiotherapy followed pre- chemoradiation ventriculo-peritoneal shunt insertion for obstructive hydrocephalus. The patient’s clinical condition improved following the ventriculoperitoneal shunt insertion as walking became re-established. Post – chemoradiotherapy cranial CT scan showed complete tumour regression. Tissue diagnosis may allow for precise, targeted management of pineal region tumours. However, in the absence of facilities which enable safe neurosurgery, resorting to the traditional chemo-radiation is still a viable alternative
松果体区肿瘤可能只影响相对较小的神经外科患者,但由于其难以接近的深层位置和周围复杂的神经血管结构,它们给神经外科医生带来了巨大的手术挑战。我们提出一个病例报告的病人谁联合放化疗没有组织学诊断,但有完全的肿瘤消退。顺铂、依托泊苷、博来霉素周期性联合化疗治疗梗阻性脑积水,放化疗前行脑室-腹膜分流术。在脑室-腹膜分流器置入后,患者的临床状况改善,行走恢复正常。放化疗后头颅CT显示肿瘤完全消退。组织诊断可能允许松果体区域肿瘤的精确,有针对性的管理。然而,在缺乏安全的神经外科设备的情况下,诉诸传统的化学辐射仍然是一种可行的选择

The methanol extract of Securidaca longepedunculata root bark was screened phytochemically and its intraperitoneal acute toxicity evaluated in mice. The phytochemical screening was carried out based on standard methods. The Median Lethal Dose (LD50 ) was determined using Lorke’s method while the Maximum Tolerated Dose (LD0 ) was determined by the method described by Mosser and Padilla. The root bark extract revealed the presence of carbohydrates, terpenoids, cardiac glycosides, saponins and flavonoids. The extract produced intraperitoneal LD0 and LD50 values of 6.92 mg/kg and 6.0 mg/kg, respectively. Based on the research findings, the methanol extract of S. longepedunculata root bark was found to contain important phytochemicals which may be attributed to its enormous use in traditional medicine, but it was a highly toxic extract in mice with intraperitoneal LD50 and LD0 values of 6.92 mg/kg and 6.0 mg/kg, respectively.

Phyllanthus amarus is an important medicinal plant that is widely distributed in all tropical and subtropical regions of the planet and has the ability to prevent and treat several human and animal diseases but has been associated with pathological defects on various organs on dose-dependent pattern. This study was carried out to evaluate Phyllanthus amarus leaf meal (PALM) for hepato-nephro-protective potentials in broiler chickens. One hundred and twenty (120) day old marshal broiler chickens were used for the experiment that lasted for 56 days. The birds were randomly allotted to five treatments of T0 (control, no PALM), T1 (2.5g/kg PALM), T2 (5.0g/kg PALM), T3 (7.5g/kg PALM) and T4 (10g/kg PALM) in a complete randomized design (CRD). Each treatment was replicated thrice with 8 birds per replicate. The birds were fed with commercial Top® feed and water was given ad-libitum. At the end of the experiment, blood was aseptically collected via venipuncture from a randomly selected bird per replicate to determine the serum biochemical parameters and later was humanely sacrificed for organs harvest. The liver and kidney were carefully dissected out and fixed in buffered 10% formalin for histological study. The biochemical data were subjected to analysis of variance (ANOVA) and statistical difference in means was separated using Duncan’s Multiple Range Test. The histo-pathological slides were interpreted by experts. ALT for T1 – T4 were statistically similar but differed significantly (P<0.05) from T1 . The ALP, however, showed T2 – T4 differing significantly (P<0.05) from T0 and T1 . The uric acid was highest in T4 and differed significantly (P<0.05) from other groups. The urea was highest in quantity in T3 and T4 and as well differed significantly (P<0.05) from other treatments. Therefore, the results showed significant differences (P<0.05) across treatment groups except for AST. PALM gradually increased the ALT, ALP, uric acid and urea in a dose dependent manner across treatments except urea that slightly decreased at T4 . The findings indicated that the PALM had varied time and dose dependent pathological effects on the liver and kidney of treated groups. It can therefore be concluded that PALM enhances serum biochemical parameters and has deleterious effects on the cyto-architecture of liver and kidney. It is recommended that PALM (crude) up to 2.5 g/kg should not be administered protractedly in chickens since it could constitute damage to visceral organs.
毛茛是一种重要的药用植物,广泛分布于地球的所有热带和亚热带地区,具有预防和治疗多种人畜疾病的能力,但与多种器官的病理缺陷有关,呈剂量依赖性。本试验旨在评价毛茛叶粉(PALM)对肉仔鸡的肝肾保护作用。选用120日龄元帅肉鸡120只,进行为期56 d的试验。试验采用完全随机设计(CRD),随机分为T0(对照组,无PALM)、T1 (2.5g/kg PALM)、T2 (5.0g/kg PALM)、T3 (7.5g/kg PALM)和T4 (10g/kg PALM) 5个处理。每个处理重复3次,每个重复8只鸡。用Top®商业饲料饲喂,水随意饲喂。实验结束时,每个重复随机选取1只鸡无菌穿刺采血,测定血清生化指标,然后人道处死,取器官。仔细解剖肝脏和肾脏,将其固定在10%福尔马林缓冲液中进行组织学研究。生化数据采用方差分析(ANOVA),均数统计学差异采用Duncan多元极差检验(Multiple Range Test)分离。组织病理切片由专家解释。T1 ~ T4的ALT与T1比较,差异有统计学意义(P<0.05)。与T0和T1相比,ALP显示T2 - T4差异有统计学意义(P<0.05)。T4组尿酸最高,与其他组比较差异有统计学意义(P<0.05)。T3和T4期尿素含量最高,与其他处理差异显著(P<0.05)。因此,除AST外,各组间差异均有统计学意义(P<0.05)。除尿素在T4时略有下降外,PALM各组间ALT、ALP、尿酸和尿素均呈剂量依赖性逐渐升高。结果表明,棕榈叶对治疗组肝脏和肾脏的病理作用具有不同的时间和剂量依赖性。由此可见,棕榈可提高血清生化指标,并对肝脏和肾脏的细胞结构产生有害影响。建议不应长期给鸡注射2.5 g/kg的棕榈(粗),因为它可能对内脏器官造成损害。

Preliminary Qualitative Evaluation of the Anatomical Structures for Vocalization in the Chicken (Gallus gallus domestica) 鸡(Gallus Gallus domestica)发声解剖结构的初步定性评价
Pub Date : 2021-01-01 DOI: 10.36108/jvbs/1202.30.0130

The anatomical structure of phonation in the domestic chicken Gallus gallus (red jungle fowl, forma domestica) of both sexes was studied to determine sex variations in structures. Ten (10) birds, involving 5 males and 5 females were obtained from a local market for student demonstrations and used for this study. Tracheal rings were observed to be made of circular cartilages numbering thirty and above with the distal most (1/5) tracheal rings narrowed, calcified and fused as the tympanum making part of the Syrinx. The rings become calcified and somewhat collapsed through the bronchial bifurcations. When squeezed, the trachea collapsed completely between fingers but could at releasing the fingers be raised up due to elastic components separating the rings from one another. Other structures involved in vocalization includes straps of muscles. Male structures involved in respiration and vocalization were well formed compared to those of the female. Both tracheobronchialis lateralis and ventralis muscles were thicker than those of the female. Male tracheobronchialis ventralis and dorsalis muscles were well formed and spindle shaped. However, the female tracheobronchialis muscles were seen to be wider compared to the male. The vocal organs (voice box) were seen to be arbitrarily triangular in structure at the bifurcation of the trachea in both sexes. The male Syringeal walls were thinner and were seen to have marked inter Pessula space. The Pessulus mark an abrupt change from the circular trachea to strongly elliptical entrances to the bronchi. It was concluded that the differences in the thinness of syringeal walls coupled with differences between the males and females in other tracheal muscles might be responsible for the stronger vocalization in the male.
研究了两种性别的家鸡(红色丛林家禽,家鸡)发声器官的解剖结构,以确定其结构的性别差异。10只鸟,雄性和雌性各5只,从当地市场获得,用于学生示范。气管环由30个或以上的圆形软骨组成,其中最远端(1/5)气管环变窄、钙化并融合为鼓室,构成鼻咽管的一部分。肺环钙化,并在支气管分叉处塌陷。当被挤压时,气管在手指之间完全塌陷,但在释放手指时,由于弹性成分将环分开,手指可以抬起。与发声有关的其他结构包括肌肉带。与雌性相比,雄性参与呼吸和发声的结构形成良好。气管支气管外侧肌和腹侧肌均较雌鼠厚。男性气管细支气管腹侧肌和背侧肌发育良好,呈纺锤形。然而,与男性相比,女性的气管细支气管肌肉被认为更宽。两性在气管分叉处的发声器官(喉部)呈任意三角形结构。男性的注射器壁较薄,可见有明显的柱体间隙。导管标志着从圆形气管到强椭圆形支气管入口的突然变化。由此得出结论,雄性和雌性在其他气管肌肉上的差异可能是导致雄性发声更强的原因。
