Arthroscopy is a surgical procedure. Complications are rare, but they exist and require specific treatment. Knowledge, prevention and management of complications are part of the mastery of a surgical technique.

Distance learning over the past several years has gained in popularity not only as a way to offer instruction in locations without local expertise, but also as a cost effective method where limited enrollment at one location would not normally warrant offering the course. In this paper, we use the embedded board with interface module to implement a remote electronic measurement system which includes the power supply, signal generator and oscilloscope. This design uses an embedded board to replace a computer, since the embedded board has the advantage of being easily carried, a real-time operation, a low cost, and programmable. In addition users can operate this measurement system with the help of the operating system and the TCP/IP modules to connect to the Internet. By using the on board operating system, our design provides the step by step function to help user operate, such as keying in the waveform parameters with the embedded board keyboard, providing the waveforms and then connecting the circuit to the embedded electronic measurement system. This design can also show the waveform measured by the embedded measurement system in the embedded board LCM (Liquid Crystal Monitor). Because the file size of measured waveforms is very small around 1 KB, the prototype system show that the main delay time to receive the measurement waveform at the server site from the client site is within 2.5 seconds In the server, the observers can observe many waveforms from the different clients. If the client’s waveform is error, the observer can also send the required waveforms to the client’s embedded measurement system and input these waveforms to the testing circuits and re-observe the circuit measurement and help the user to debug.

The research was performed to study effect of Leadership Development on Employee Performance as well as organizational performance in Punjab, Pakistan. More particularly the research was performed in banking sector and several banks within Punjab province are included. The research focused the three variables for the study such that Training and Development, Employee Participation and Employee Empowerment. These three variables are studied inter-related to each other effecting the employee performance. Though study which as performed to find that, these variables effect employee performance with about 50% while other 50% is effected by other internal forces and contributes towards attitude, commitment, rewards and incentives etc. On the other hand organizational performance do effected by these variables but external environmental factors also effects the performance of organization. Study also attains that certain leadership styles are essential to increase the employee and organizational performance. Thus study shows that these three variables are major tools to increase employee performance in order that learning and training capacity of employee and manager should be valid and have positive approach towards the leadership development program. Though manager and employees should work and collaborate with each other for better performance and should also communicate with each other for increased performance.

Estimating the design flood is one of the main steps in designing and measuring different structures and hydraulic facilities which could be conducted in different ways. In cases where the saving capacity of the system would be significant or period of the design flood would be long (For example in designing the overflow of dams), using mathematical models for converting the design rain into the design flood is a common option. The selected design rain which will generate the design flood should possess some characteristics among which would be the way of rain distribution during raining time which is expressed as the temporal pattern of the design rain. In this study, this method has been employed in order to extract the pattern of the design rain by means of the data related to the stability rain gauge in Jashlobar region and by being supported by pilgrim method in Australia which has had good compatibility and agreement with the climate conditions in Iran and had publicity. According to temporal changes in the intensity of the flood rains, recognizing the precise temporal patterns of the rain in a region is of great importance. In this research, in order to extract the most appropriate temporal patterns, cloudbursts were divided into continuities of 1, 3, 6, 9, 12, 18, 24 and 48 hours. Initially, all data and information related to the occurred cloudburstsin the region and the runoff and precipitates samples were taken from the research center of Semnan and the data were categorized through an exact investigation of the status of each cloudburst which led to a division into data related to runoff and the ones without runoff. Thereafter, the suspicious data were omitted and in the next step, the characteristics of the rains were extracted which required the graph of all cloudbursts to be created. At first the characteristics of the cloudbursts and the pattern of the rains distribution through pilgrim method and then the amount of rain in the area in each quarter was specified. Then, the average between the census obtained from both sites were calculated and the graphs of the rain patterns, with and without runoff, were provided and the intersection point of two graphs of erosion and precipitation threshold limit has been determined through adapting the graphs with and without runoff.

The study was carried out for two winter seasons of 2015/2016 and 2016/2017 at the Demonstration farm of Faculty of Agriculture and Natural Resources ,University of Kassala ,Halfa aljadidah. The objective of this to study the effect of sowing date and faba bean cultivar on the icidence of the leaf miner in faba bean. The Four cultivars were Hudeiba93, SML, Bassaber, Elddamer while three sowing dates were 5 November, 20 November and 5 December. Data were recorded for leaf miner infestation and grain yield components (number of pods, weight of 100 seed and seed weight kg /ha ).The results indicated that mean number of mines of L.trifolii in the third sowing date higher than those of first and second sowing dates, respectively. Also ,the highest number of pods per plant (6.27) was recorded in Hudeiba 93 which was significantly higher than SML cultivar. Moreover, the highest seed yield (871kg /ha) was recorded from Eddamer followed by Hudeiba 93(792kg /ha) and Bassaber (755 kg/ha) while lowest seed yield of (571 kg/ha) was recorded from SML. In conclusion, the highest seed yield of 1017kg /ha was recorded in Eddamer at second sowing date.

A computer oriented numerical approach to study the effects of variable viscosity and thermal conductivity of stagnation flow of a micropolar fluid towards a vertical permeable surface is investigated in this study. The external flow impinges normal to the heated plate and we have assumed the viscosity and thermal conductivity as the inverse linear function of temperature. The partial differential equations governing the problem under consideration have been transformed into a system of non-linear ordinary differential equations by the similarity transformation and solved them numerically by shooting method. Numerical results are carried out for various dimensionless parameters of the problem especially variable viscosity parameter, thermal conductivity parameter, micro-rotation parameter along with the Prandtl number. The results are presented graphically for velocity distribution, temperature distribution and micropolar distributions for various values of non-dimensional parameters. It is found that the effects of the parameters representing variable property of viscosity and thermal conductivity are significant.

Environment is a very wide term which includes everything in all its manifest forms, on the earth, beneath the earth and above the earth. The natural resources of a nation affect the business activity of every enterprise. Similarly, the functioning of an enterprise has some favorable and some adverse effects on the environment. Hence, there is a need for maintaining accounts of the effects of the activities of a business entity on the environment and on natural resources. Environmental accounting is a faithful attempt to identify and bring to light the resources exhausted and cost rendered reciprocally to the environment by a business corporation. It is henceforth concerned with recording environmental elements. Environmental accounting is still at an early stage of evolution and it is being groomed under the voluntary leadership of a variety of enterprises around the world. During the period of 1981-1990, the emphasis in the accounting literature shifted from ‘social responsibility accounting’ to ‘environmental accounting’, reflecting the strong interest in the latter. From 1990-todate, the emphasis on environmental accounting continues unabated and engages the interest of both academic and practicing accountants, hence accounting and disclosure of environmental matters have been rapidly emerging as an important dimension of corporate reporting. This paper describes the evolution, nature, significance, areas and methodology of environmental accounting and also examines general issues concerned with it. This paper throws light on how corporate are responding to pressures to keep accounting records of the impact that their productive process have on the environment.
