1. Solar-Powered Volumetric Infusion Pump   


Infusion pump safety has been a concern of the healthcare industry for a long time, to reduce infusion medication errors by implementing various technologies. One such technology on the rise today is the use of renewable energy – especially solar energy - for reliable and resilient healthcare in clinical settings in remote areas and has a positive impact on the environment too. Similarly, wireless connectivity and telemetry have become a recent trend in topics of healthcare innovation. A methodology with cloud server has enabled the integration of data from anywhere in the world breaking the limits of a traditional server situated in one establishment. Thus, this research has enabled the integration of infusion pumps into hospital systems as well as real-time remote monitoring of patients thereby reducing clinicians’ workload and infusion related medical errors significantly. Also, the extended battery life (Backup battery system) in off-grid areas during situations like power outages was implemented in a low-cost, reliable, and accurate manner. All this combined provided an affordable, convenient, almost faultless, and scalable infusion system. This helped to increase infusion safety through real-time monitoring.

2. Review Different Types of Enhancement on Double Pipe Heat Exchangers by Using Fins 


     A wide range of research have been conducted to increase heat transfer rate while also reducing the size and cost of the industrial equipment in accordance with the growing demand to create and improve the efficacy of heat exchangers. The twin pipe heat exchanger is one of the numerous tools utilized in various industries. Due to its ease of use and variety of applications, this type of heat exchanger has garnered considerable interest. Many thorough research projects on twin pipe heat exchangers have been carried out recently. In heat exchangers, expanded surfaces or fins are typically employed to improve heat transmission between the primary surface and the surrounding fluid. Different geometrical configurations have been employed with various types of simple-shaped fins, including rectangular, square, annular, cylindrical, and tapering fins. Various tests have also been conducted for creating optimal fins to meet industry need. Fin optimization may be carried out by either improving heat dissipation at a particular fin weight or by precisely reducing the weight of the fin. There has also been a significant amount of recent study on several common fins, such as porous fins and perforated fins. In this review, the development procedure that this type of heat exchanger went through has been analyzed in details and the heat transfer enhancement methods in aforementioned heat exchangers have also been widely discussed.

3. Diagnosing the Effect of Applying Continuous Improvement According to the Tenth item of Standard 9001: 2015 In Agile Manufacturing: Case Study at Al-Zawraa General Company for Electrical Industries  


This paper aims to identify the reality of continuous improvement and its role in achieving effective manufacturing strategies and contributing effectively to the development of effective strategies to meet the economic, social, and, cultural challenges facing business organizations. Use the checklists from the international standard ISO 9001: 2015 to analyze the gap between the reality of the state of the system in the Al-Zawra General Company for Electrical Industries based on the data and information collected through personal interviews and field visits to the company and the descriptive aspect was relied upon by a questionnaire to collect data through the statistical program (Spss Var.25). The study concluded that the company's understanding of the application of continuous improvement in accordance with Article 10 of standard 9001: 2015 contributes to giving a clear vision and working with an agile manufacturing system to achieve high quality.

4. Global Food Security and Poverty induced by the Pandemic


This Covid19 pandemic is a health and Human crisis threatening the food security and nutrition of millions of people around the world. It made many poor communities face very challenging livelihood consequences. Hundreds of millions of people were already suffering from hunger and malnutrition and this corona virus pandemic has just added a more to it. As more than 2billion small producers, farmers, laborers, rural workers and their families who represent a longer portion of food systems related to work to secure their own lives the moderately and severely food increase, maybe disproportionately affected by economic shock. The developed and developing countries all are sufferer of this pandemic but in the long run the developing countries pays the most as they don’t have the reserve food or economic backup like the developed ones. Initially the poor and middle income people around the world who's income are already less becoming the worst sufferer of this Covid19 pandemic. This paper targets to analyze how the pandemic causes difficulties to the impoverished by presenting the hunger and food insecurity and livelihood problems increasing around the world. This research points out how it is hard on the poor to adhere the restrictive measures of the social isolation and different measures to minimize the problems and risks arises because of the Covid19 pandemic on poor and middle-income people’s life are suggested.

5. Effect of Barite as a Weighting Agent on the Properties of Non- Newtonian Fluids


The reearch deals with the behavior of non-newtonian fluids under the increasing of cocentrtion of the weighting agent,which is barite. Non-Newtonian fluids were prepared with a constant concentration of CMC which is 2g/500cc. A weighting agent, which is barite was added with different concentrations (11,13,21,27, and 39(gm/500cc)) to the prepared non-Newtonian fluids. It was found that shear stress increases with increasing of shear rate from plotting of shear stress with shear rate for each mixture. It was found that both yield point and plastic viscosity increased with increasing of concentration of barite. Also it was found that the density increased with increasing of concentration of barite.
