Any circuit however big or small, liner or non-linear, ohmic or non-ohmic follow Kirchhoff’s current law (KCL) and Kirchhoff’s voltage law (KVL), using these laws along with some other techniques to determine the currents and voltages in a given circuit. Supermesh is applied, if current source is common to more than one mesh current. In this paper, for a given circuit, suggesting an alternative method for supermesh. The alternative method is applicable for planar circuit. The circuit is redrawn such that the current source is not being common for more than one mesh current .i.e.

Present day solar cell industry is completely dominated by the use of silicon as the active material. Silicon material is used to manufacture solar cells due to its low cost, abundance in nature, non-toxicity, long term stability, and well established technology. Enhancing the efficiency of silicon solar cells by nanoparticles has become a new trend in solar cell technology. Recently a new method for increasing the light absorption has emerged by the use of scattering from noble metal nanoparticles excited at their surface plasmon resonance.

Aim: The purpose of this study is; to investigate the relationship between the grip strength and some of arm angles of university tennis players with the age of the sport and to investigate the effect of sporting age on grip strength performance. Material and Methods: 40 female and 50 male volunteer tennis players attending the Turkish Universities Tennis Championships organized in Marmaris in 2016 participated the research as subject. The grip strengths of the subjects were tested with three maximal repetitions with dominant and non-dominant hand with Takai brand hand dynamometer.

Mercury occurs naturally in unprocessed hydrocarbon streams, which can damage the equipment and contaminate the treatment fluids as well as pose a health risk to workers and the environment. Mercury was determined in all stream fluids for sweetening process (Benfield solution process) and composition analysis also determined to evaluate the performance of the process. Fourteen samples were collected from natural gas, Benfield solution, water, sludge and solid samples. Mercury was measured on-site for gas streams using cold vapor atomic absorption (CV-AAS) technique.

Introduction: Introduction: Systemic arterial hypertension (SAH) is the main factor for cardiovascular diseases (CVD). HBP is a clinical condition that involves many factors characterized by elevated and sustained blood pressure (BP) levels. Objective: to evaluate the frequency of cardiovascular brain events in hypertensive patients who control or not blood pressure. Methods: a descriptive cross-sectional study was carried out in which the frequency of cardiovascular brain events in hypertensive patients with and without BP control was evaluated.

The post - harvest residue of rice (Oryza sativa) and watermelon (Citrullus lanatus) in the state of Tocantins, mainly in the region of Formoso do Araguaia, where the highest production of these products in the state is concentrated, may serve as a substrate for obtaining hydrolytic enzymes and oxidative stresses involved in the degradation of lignocellulosic materials by Pleurotus ostreatus grown in solid state.

Smart textiles can be defined as materials that perceive and respond to an external stimulus. Interest in smart textiles has increased significantly in the academic area in recent years. As shape memory textiles respond to external stimuli (heat, light, electricity etc.), they are examined as a branch of smart textiles. Shape memory polymers (SMP) and alloys (SMA) can be used in various textile applications. In this study, general properties of shape memory alloys and polymers as well as the differences between these two materials have been mentioned.

Aim: The aim of this paper was to characterize the active ingredients of ACP remineralizing pastes MI PasteTM and MI Paste PlusTM. Materials and Method: Two CPP-ACP containing products MI PasteTM and MI Paste PlusTM with addition of 900ppm sodium fluoride (NaF) supplied by GC America Inc. were evaluated. The free fluoride content of MIPaste PlusTM was quantified using a fluoride ion selective electrode (Orion 9609BN, 710A meter, South Burlington, VT, USA). 1.50 g of MI Paste PlusTM was dissolved thoroughly in 100 ml de-ionized water. Samples were prepared in duplicate.

Irrigation system in India has given a high priority in economic development. Many new concepts are being developed to allow agricultural automation to flourish and deliver its full potential. Implementation of Hi-tech Agricultural Solar Fence Security with soil Humidity Based Automatic irrigation system and voice alert on PIR live Human Detection is been implemented in this project for safe and secure agriculture irrigation. The project irrigation control using AT89S52 is designed to tackle the problems of agricultural sector regarding irrigation system with available water resources.

Results-Based Management (RBM) is a system that should be incorporated into the culture of the department and its programme of projects including its operational systems, values and decision-making procedures. The employee’s skills and capacity should focus on achieving outcomes and impact rather than activities and inputs. In general, a result is something that arises as a consequence. The key principle in this article is to understand the three levels of the results chain, namely: outputs, outcomes and impacts.
