SOFT SKILLS - DIFFERENT ASPECTS AND IMPORTANCE IN CAREER DEVELOPMENT

[Vol. 03 (01), December, 2022, pp. 1-4]

In this present 21st century competitive world, getting success depends on various factors and skills, apart from traditional learning. Inculcating skills like Communication, Team work, Time Management, Work ethics not only gives an advantage, but has become a pre-requisite for a successful professional career. These skills are essential personal skills and social capabilities people need to be able to perform most jobs. This paper focuses on soft skills and its different aspects and how it becomes an essential criterion for career development.

EFFECT OF pH ON TURNOVER NUMBER OF A BINUCLEAR AND MONONUCLEAR COMPLEX: A COMPARATIVE STUDY

[Vol. 03 (01), December, 2022, pp. 5-17]

A reported binuclear Cu(II) complex of the type [Cu2(L1)2] [L1 = 2- Hydroxy-3-[(2-hydroxyethylimino)-methyl]-5-methyl-benzaldehyde] and another reported mononuclear Cu(II) complex [Cu(L2)2](ClO4)2 [L2 = 2-[(phenyl-pyridine-2-yl-methylene)-amino]-ethanol] were investigated for pH dependent catecholase activity in which 3,5-di-tertiary-butylcatechol was oxidized to 3,5-di-tert-butyl-obenzoquinone derivative, in methanol (MeOH) solvent. A comparison was made with reference to the turnover numbers for the catalytic activity in basic medium for the mononuclear and the dinuclear complexes.

OVER VIEW OF ELECTROMAGNETIC BRAKING SYSTEM

[Vol. 03 (01), December, 2022, pp. 18-23]

Electromagnetic braking system is based on the principle of electromagnetism to achieve friction less braking in which applying brakes using electronic and magnetic power. This increases the lifecycle and trustworthiness of brakes since no friction leads to less wearing out of brakes. This is imminent of braking systems. It is smaller in size compared to the traditional braking systems. when magnetic flux passed in a perpendicular direction to the rotating wheel, an eddy current flow in a reverse to the rotational direction of the wheel. This produces an opposing force to the rotation of wheel and in turn reduces the speed of wheel rotation. It develops a torque and finally the vehicle comes to rest. This braking system can be combined in heavy vehicles as an auxiliary brake. It can be used in commercial vehicles by monitoring the current supplied to generate the magnetic flux. As per the requirement of vehicle pilot a required torque can be generate to slow down the vehicle. This new braking system minimize the road accident now a days. This paper is focused on basic summarized version of electromagnetic braking system including types, component, construction, working principal, application and it s future scope of application and modification.

OVER VIEW ON WATER GENERATION FROM ATMOSPHERIC AIR

[Vol. 03 (01), December, 2022, pp. 24-28]

Water vapour in the air can be extracted by condensation - cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidifier, an ATMOSPHERIC WATER GENERATOR(AWG) is designed to render the water potable. AWGs are useful where pure drinking water is difficult or impossible to obtain, because there is almost always a small amount of water in the air that can be extracted. The two primary techniques in use are cooling and desiccants. Many atmospheric water generators operate in a manner very similar to that of a dehumidifier: air is moved over a cooled coil, causing water to condense. The rate of water production depends on the ambient temperature, humidity, the volume of air passing over the coil, and the machine's capacity to cool the coil. These systems shrinkage air temperature, which in turn reduces the air's capacity to carry water vapour.

A REVIEW OF MICROSTRIP PATCH ANTENNA AND PERFORMANCE IMPROVEMENT TECHNIQUE

[Vol. 03 (01), December, 2022, pp. 29-36]

Microstrip patch antenna is a scientific field of research that has opened the door to 5G communication and future 6G communication devices. Initially the microstrip patch antenna was designed in rectangular, circular, and triangular shaped and later to improve the antenna parameters, several modifications have been done in the patch structure as well as in the ground plane structure which is basically called its structural improvement/modification. Such modification helped to cover multiband, broadband, and wideband characteristics in the 5G frequency spectrum. Many performance improvement techniques are reviewed and presented in this paper. This paper also covers the necessary improvement of antenna performance parameters while geometric modifications have done.
