The study was carried out exclusively in Ghana to explore the approaches employed by consultants in risk assessment at the design phase of projects in Ghana. One hundred and fourteen (114) consultants were selected out of a population of one hundred and eighty six (186) from three main professional associations in Ghana made up of the Ghana Institute of Architects, Ghana Institution of Engineers and the Ghana Institution of Surveyors (Quantity Surveying Division) practicing in Ghana for the study. Both primary and secondary data were collected. A descriptive survey was also used to observe and describe the presence, frequency or absence of characteristics of a phenomenon as it naturally occurred, in order to gain additional information. A questionnaire was also designed to collect data from the architects, engineers and quantity surveyors. The data was analyzed using Statistical Package for the Social Scientists (SPSS) 17.0. Descriptive and inferential statistics, such as frequency tables, percentages and cross tabulations were used in the data analysis and summaries. Simple tests of associations were undertaken by using Chi square and Cramer’s V statistics to compare relationships between variables. Again, relative importance index was also used to analyze some of the data by computing to deduce their rankings. The relative importance index was used to analyze some of the data by computing to deduce their rankings. The research revealed that majority of consultants had an average knowledge of risk management. Based on the findings it was recommended that consultants undergo advanced training in risk assessment. It was therefore suggested that consultancy firms should develop a set of laid down procedures for consultants to use in risk assessment in order that the use of intuition employed by majority is lessened. The challenges observed in risk assessment and the remedial steps suggested curtailing the detrimental effects of risks would be of wide importance to man

The potato (Solanum tuberosum L.) is a vegetable that ranks fifth in the world for human consumption. Its importance is growing more and more in the Senegalese diet. However, the potato production in Senegal does not meet the needs of the market, which maintains dependence on the outside for the supply of quality seeds. In addition, these imported seeds do not often have phytosanitary qualities required for local production in the Sahelian zone. The in vitro production of microtubers, used as seed, has been shown to be one of the most efficient means for propagation of basic material. To overcome the constraints linked to the supply and availability of potato seeds, with high germination capacity, the impact of the microtuber size on the yield of the plants under semi-controlled conditions was examined. The pre-germinated microtubers were produced in vitro from vitroplants of 3 different varieties (Aida, Atlas, Odessa) adapted to the edaphic-climatic conditions of Senegal. The effects of the seed sizes of microtubers, greater than 4 mm, sown under semi-controlled conditions, on the yield of the plants,mily:Verdana;"> result in an increase in the ratio, in the vegetative development of the plants, but also in the number and size of the minitubers harvested. The yield of the

为了准确估计永磁同步电机(PmSm)的转子位置和转速,并实现无机械传感器矢量控制,提出了一种基于扩展Kalman滤波器(EKF)的转子位置和转速观测器,适合于求解永磁同步电机的非线性方程。观测器状态方程采用转子磁链定向的同步旋转坐标系下的电压方程,电感等参数为常数,可以应用于凸极机和隐极机。对扩展Kalman滤波器进行了算法简化,使它可以实用化。把负载转矩作为状态变量,观测器可以同时观测负载转矩,并把观测转矩用作前馈补偿,提高了系统的动态性能。通过实验验证了系统的性能。

We describe a specific procedure for the synthesis of deuterium-labelled 2-（1-methylalkyl）succinate established via alkylation of diethyl malonate, Krapcho decarboxylation reaction with D20 and hydrolysis reaction. Two novel compounds, 2-[^2H]-2-ethylsuccinic acid and 2-[^2H]-2-（1-methylhep- tyl）succinic acid were prepared via this synthetic route and characterized by mass spectrometry and ^1H NmR. The results showed that the 2-（1-methylalkyl）succinic acids were deuterated at the β-position, which is considered as an important reaction centre in the anaerobic degradation of n-alkanes.
