Abstract

Naltrexone is a non-selective opioid antagonist, which shows effects on delta, mu and kappa receptors. Its therapeutic use is designed for drug addicts' treatment, reducing withdrawal side effects. However, several researchers have used low-dose Naltrexone (LDN) for therapeutic purposes in diseases associated to immune system deficiency and inflammatory and tumor processes. Consequently, enhance evidences that LDN use hypothesis promotes, through a compensation mechanism, an increase of endorphins and enkephalins, in addition to opioid receptors up-regulation mechanism, in Central Nervous System (CNS), becoming it a potentially effective clinical practice in these pathologies. Thus, we present a review about LDN use in different pathologies, all they published in literature, and its therapeutic effects, enabling us to conclude that 3.0-4.5mg/day dose use in humans is effective for idiopathic diseases with alterations in immune system, as well as those ones with inflammatory and tumor characteristics.

Abstract

The inhibitive effects of New bouldiaLaevis (NL) leaf extract and magnetic field on copper corrosion in 0.5M H2SO4 aqueous solution were investigated experimentally by gravimetric technique and theoretically using Quantum Chemical calculations. The results show that both NL and the magnetic field caused reduction in corrosion rate. The inhibition efficiency increased with concentration. The magnetic field caused greater increase in the inhibition efficiency. Temperature increase caused a decrease in inhibition efficiency. The activation energy is low and oscillates, possibly due to error factor from non-linearity of the Arrhenius plot. Among the tested isotherms, Langmuir has the highest correlation coefficient of 0.9963 and 0.7935 with and without magnet field respectively. The magnetic field increased the change in free energy, caused the reaction to become spontaneous, one mole of the inhibitor to replace 4 moles of water mole while reducing the number of monolayer of the inhibitor on the metal. The quantum chemical calculations performed on new bouldiaquinone and lapacholconstituents of NL showed that lapachol contributed more to the inhibition efficiency due its low binding energy, high dipole moment, chemical softness and fractional electron transfer. The magnetic field and temperature played opposite roles.

Abstract

Cold plasma is an emerging non-thermal technology for the improvement of food safety. This technique becomes a subject of high interest for a wide variety of technologies including the food industry. Cold plasma is a novel non thermal food processing technology that uses energetic, reactive gases to inactivate contaminating microbes on meats, poultry, fruits, and vegetables. The atmospheric cold plasma is proposed for decontamination of fruits and vegetables, especially, without changes in sensory attributes. Growing demand for fresh produce poses the challenge to the food industry of supplying safe food with minimal processing. It is crucial that foods are supplied without any microbial contamination as many products are eaten raw. Cold atmospheric plasma has potential in the food manufacturing sector to inactivate microorganisms, thereby improving food safety without loss of physicochemical or sensory properties

KEY WORD: Food preservation, food safety, micro-organisms, non thermal plasma, sensory attributes

Research Inventy: International Journal of Engineering & Science , Volume 6 ~ Issue 2 (February 2016)

Paper Index :: : 07.4721/xxxxxxx
Abstract

This paper reports on the Information Systems (IS) securitymeasures implemented by small and medium size enterprises (SMEs) in Zimbabwe. A survey questionnaire was distributed to 32 randomly selected participants in order to investigate the security measures and practices in their respective organisations. The results indicated that over 50% of the respondents had installed firewalls, while more than 80% carried out regular software updates and none of the respondents had intrusion detection systems. The researchers recommended that SMEs work to enhance their knowledge on the different IS threats in order to enable the implementation of preventive measures.

Research Inventy: International Journal of Engineering & Science , Volume 6 ~ Issue 2 (February 2016)

Paper Index :: : 07.4721/xxxxxxx
Abstract

Appari's design of fan for residential and public buildings is effective to give the maximum wind from the same capacity of the motor. Also it can be used for wind mills. It is very simple and very effective to generate the wind energy. Also it works when there is not sufficient wind. The combination of the blade angles bent zero to ninety degrees along with black and white coloured blades will prove very effective to develop the maximum wind energy. The same fan blades can also be used for vehicles and helmets. If the same blades are used along with one dynamo and small bulb fitted in the fan portion will work effectively to give the sufficient light, which is produced by the wind and light & heat generated from the sunlight.

KEY WORD: Fan Wind Mill, Wind Energy and National Economy.

Abstract

The bumper beam is fixed to front portion of the automobile structure and it is one of the primary component which undergoes damage and transfers the forces to the rest of the structure. Thus the modern bumper beam systems should play a key part in the safety concept of an automobile, ensuring that minimal accelerations are transferred to the passenger. Further the automotive producers are demanding for robust bumper beam systems showing good and reproducible impact behavior. The objectives of this study were to increase the physical understanding of the different phenomena taking place during the offset impact of an automotive bumper beam-longitudinal system as well as to validate a modeling procedure for the system's crash performance. In presented work the attempt has been made with Simulation of forming process for generating the FE-model of the bumper beam with required curvature. Finally the design and analysis bumper beam subjected to offset impact loading with different materials using FE-code ANSYS-LS DYNA and suggested the best material.
