— In order to have drinking water, some countries have to use chlorine. It is use cause is effective and it's cheap. An alternative to this process is the UV disinfection of drinking water. Most of the devices in the market use UV bulbs or mercury lamps. The UV LED, which is cheaper and smaller, allows creating new smaller devices. The main contribution of this paper is the use of Genetic Algor...

The effect of tenotomy on the regeneration of anterior tibial muscle was studied in Wistar rats. Regeneration was induced by intramuscular injection of a local anesthetic, and tenotomy was performed at varying intervals post-injection. Muscles were examined using light and electron microscopy 30 days after sectioning the tendon. Results showed that tenotomy failed to prevent new muscle fibers f...

Tissue repair after injury is generally inversely related to the extent of scarring, suggesting the possibility that regeneration could be promoted by interventions that inhibit scar formation. New work by Dulauroy et al has identified a myofibroblast progenitor with pericyte characteristics as an important mediator of scarring in skin and skeletal muscle after injury. The genetic ablation of t...

Description: The goal is to increase the efficiency and reduce the cost of solar power through the integration of PV, Li-battery, and LED lighting technologies. Since all components are in the form of thin films, the PV/battery/LED system can be integrated as a single module. Since half of the materials cost of each device is the substrate, integrated module will also reduce materials costs and...

■ There are not enough “before and after” studies in the literature to be certain of impacts in different circumstances and over time, and particularly in terms of town centres. Better town centre and retail monitoring would deliver benchmarking for assessing impacts and changes. Literature review: policies adopted to support a healthy retail sector and retail led regeneration and the impact of...

Background The severely limited ability of the heart to repair itself following infarction has led to the development of a number of novel cell therapies aimed at stimulating myocardial regeneration. One promising technique is cellular monolayers consisting of fibroblasts and cardiomyocytes applied directly to the infarct region to promote regeneration. The study aims to assess the success of t...

LED lighting has the potential to offer many benefits to the user and to society as a whole. Very high efficiency together with extremely long life expectancy of the LEDs reduces the energy consumption and the use of resources, and can offer low lifecycle cost. In order to become widely accepted, LED lighting must provide dimming capability at least equivalent to that offered by traditional inc...

Tef [Eragrostis tef (Zucc.) Trotter] is the major cereal crop in the Horn of Africa particularly in Ethiopia where it is staple food for about 50 million people. Its resilience to extreme environmental conditions and high in nutrition makes tef the preferred crop among both farmers and consumers. The efficiency of in vitro regeneration plays significant role in the improvement of crops. We inve...

due to climate changes in recent years, in order to attain comfort and convenience, demands for heating, ventilating, and air conditioning (hvac) systems have been increased around the world, which has led to increases in emissions and power. desiccant cooling systems (dcss) are designed and built to reduce moisture and power consumption, create comfortable conditions for people in a building, ...
