The paper deals with the assessment of the feasibility of wind farming at the 16 sites scattered in different ecological regions of Nepal. The wind speed, the hourly and seasonal variation of wind, the wind-rose, the wind turbulence rate, the wind power density, the weibull probability distribution and the frequency of the wind speed above cut in speed were computed. The average wind speed at all the sites was found to be higher during the dry season from March to May. The wind speed of the modern turbine for power generation at eight sites was found to be above cut-in speed. However, the wind power density was found to be good only at the two sites and fairly good at the six sites. More than 50 percent time of a year at these eight sites had over 3.5 m/s wind speed. However, the turbulence rate at all the studied sites was found to be above the acceptance range of 25 percent. Among the study sites, Kagbeni, Thini, Jumla, Ramechhap, Vorleni, Patan west, Hansapur and Baddanda were found to be technically feasible sites for wind energy generation in Nepal.

Backward linkage of garments manufacturing is fabric which is produced by yarn and yarn is made of fibers. So the main root of RMG sector is fiber. Cotton is the major fiber crop. The textile industry of Bangladesh predominantly depends on imported cotton. Annual demand is approximately 7 million bales (480 lbs. or 218 kg per bale) where, Bangladesh produces only 0.16 million bales in a year, which is less than 3% of the total requirement in spite of being agriculture dependent country. RMG sector is being contributed more than 80% of the total export earnings. This study illustrates that how we can reduce dependency on imported cotton and save the partial import cost. To keep sustainable RMG sector, Bangladesh should cultivate cotton as well as reduce over dependency on imported cotton. In a year, more than $3 billion is being spent to import cotton. If we can produce 1 million of bales in 2,42,000 hectares of land then we can save about 12% of total import, along with $279 million can be saved.

“Information technology” (IT) is used in this study to mean any computer, networking, storage, infrastructure, physical devices and software used to create, store, process, exchange and distribute any form of data. As there are advances in the capabilities of IT, companies and businesses involved in the creation of products leverage these capabilities to innovate and create new products. New product development (NPD) is a defined process for developing new products for the market and it is considered the primary step to making a product available to the market. To keep up with the market, firms must continue to innovate and develop new products to meet their customers’ dynamic needs. To highlight Information Technology (IT) used in new product development (NPD) process, an empirical research by qualitative analysis, using semi-structured interview methodology was conducted with nine start-up product development leaders. A conceptual model for the use of IT in NPD was created based on scientific theoretical literatures and the NPD framework for defining the stages of the NPD process. The study revealed that dependence on IT in NPD increases along the NPD process and the complexity of the IT tools employed also increases, needing more expertise and knowledge to maximise their use.

Sepsis is a potentially life-threatening complication of an infection. Sepsis occurs when chemicals released into the bloodstream to fight the infection trigger inflammatory responses throughout the body. This inflammation can trigger a cascade of changes that can damage multiple organ systems, causing them to fail. With the increasing population at risk of sepsis in the United States, it has become crucial to recognize signs and symptoms of sepsis; also important is to refine and develop guidelines that will reduce the mortality. This study focused on the patients of Jackson Park hospital in the ER/ICU/Floors between Jan 1, 2014, and Dec 31, 2014, and compared the appropriateness of antibiotics, their administration time, microbial isolate and site of infection to the mortality rate seen amongst the patients. All the collected data were compared using tables, pie chart and bar graphs. The study showed patients receiving antibiotics within 3 hours of arrival to the ED had a reduction in mortality by 49% with sepsis from E. coli, MRSA & other staph infections were among the most common infections leading to mortality among the patients. Lungs and UTI infections were the most common site, with respiratory tract having 27% mortality among all patients presenting with sepsis. The study allowed a prompt evaluation of sepsis screening protocol, as well as developing new protocols to include certain antibiotics readily available in the ED and antibiogram to be done for all sepsis patients.

Lidar has emerged as one of the critical components in the quest to build a fully autonomous vehicle. Its provides the spatial resolution required to accurately discern and identify a wide variety of objects and operates at ranges far enough in front of the vehicle that computational models of the environment can be built and meaningful action taken. This combination of features is not available from any competing technology such as RADAR, Ultrasonic or camera vision systems. Lidar does however, have its own set of issues which are currently preventing its adoption by auto manufacturers on mass. These are its high per unit cost, mechanical mode of operation and the correlation between accuracy, range and emission power which has to be limited in order to comply with eye safety legislation. LIRDATA is a new technology which helps to solve these fundamental drawbacks to Lidar and assist with making Lidar the primary sensor option for the Autonomous Vehicle industry.
