    Opis:
    The present experimental investigation aims to analyse the effect of various machining parameters, such as pulse peak current (Ion), pulse on time (Ton), pulse off time (Toff) and spark voltage (SV) on the surface roughness (SR) and material removal rate(MRR) by using continuous traveling of both wire electrode (i.e. brass wire and zinc-coated brass wire). The present work also analyses the effect of types of wires, such as brass wire and zinc-coated brass wire used during machining of Titanium alloy (Ti-6Al-4V) on Surface roughness (SR) and material removal rate (MRR). This work studies the correlation between various response parameter such SR and MRR by using same machining parameter by for both wires.

    Opis:
    ObjectivesThis study aimed to assess the surgical outcomes of patients with work-related upper extremity musculoskeletal disorders (UE-MSDs) who failed conservative treatment.Material and MethodsThis was a retrospective study of 17 patients who had work-related UE-MSDs and underwent the following surgeries and follow-up evaluations: decompression, external and internal neurolysis of the upper trunk of the brachial plexus and the long thoracic nerve (LTN), and a partial resection of the anterior and middle scalene muscle. A detailed history of clinical presentation including pain, physical and clinical examinations of the extent of scapular winging (ESW), and upper extremity anatomical postures, such as active forward arm flexion and shoulder abduction, were recorded before and after 3 months of the surgery. Nerve conduction velocity and electromyography examination reports were obtained to assess the sensory or motor loss of the nerve injury before their operation.ResultsAll 17 patients included in this report showed some improvement anatomically in the scapula appearance and functionally in their shoulder movements. More specifically, 9 (53%) patients got a restored to near healthy appearance of the scapula, and 11 (65%) patients recovered a full range of motion, 180° post-surgically. Overall, the mean shoulder flexion and abduction improved to 157±37.5° and 155±40.2° after the surgery from 106±30.2° and 111±34.8°, respectively (p < 0.0001). The ESW score also significantly improved from a mean of 1.5±0.51 to 3.5±0.71 (p < 0.0001). The post-surgical improvements were statistically highly significant (p < 0.0001).ConclusionsDecompression and neurolysis of the upper brachial plexus and the LTN, and the partial release of the scalene muscle contracture procedures have fostered improvements in the shoulder anatomical appearance and movements in all 17 patients.

    Opis:
    An enzyme-assisted modified steam distillation process was adopted to extract turmeric oil from Curcuma longa L. rhizomes. The diastase, xylose, cellulase, pectinase, and lipase enzymes were used for the pre-treatment of fresh turmeric rhizome to obtain a higher yield by rapturing biological cells. The quantitative and qualitative analysis of turmeric oil was performed by GC–MS. The various influencing parameters for the extraction of turmeric oil such as an enzyme, incubation/pre-treatment time, distillation time have been studied in the present work. The obtained turmeric oil by enzymatic pretreatment process is richer in bioactive/medicinal components than in the other traditional methods. The maximum yield was obtained with cellulase enzyme, which is 25–27% higher than the yield obtained by the traditional hydro distillation process. The detailed qualitative and quantitative analyses are also presented. The present method can be considered energy-efficient, effective, economical, and eco-friendly.

    Opis:
    Air pollution has a serious impact on the health of human beings and is a major cause of death worldwide every year. Out of the many sources of air pollution, the smoke generated from household combustion devices is very dangerous due to the incomplete combustion of fuel. Women from rural areas suffer a lot due to this harmful smoke. Diseases like cancer, throat, and lung infection occur in adults and children due to inhalation of this smoke. The traditional chulha used by rural women is operated by using cow dung, straw, and wood, and the air is blown manually by using small metallic pipes. This paper presents the design and development of an innovative stove to maximize flame temperature and minimize air pollution to overcome the health-related issues of rural women. A smokeless stove is presented, in which wood, straw, and cow dung are taken as primary fuel, and superheated steam as a secondary oxidizer for its operation. In this stove, a forced draft is created by the provision of a small fan, which is operated by solar power thus eliminating the need of creating a forced draft manually by the cook which makes this innovative stove superior to the traditional chulha. Owing to the provision of superheated steam, the flame temperature as well as the burning efficiency increases. The cooking time is reduced due to higher flame temperature as compared to the liquefied petroleum gas stove. The main objective of this work is to minimize air pollution and provide a smoke-free environment to the people using such devices as this innovative stove offers complete combustion of fuel. The flame temperature of the designed stove ranges from 595°C to 700°C and its thermal efficiency is 10–17% higher than that of the traditional chulha. The design of this stove is unique, and its maintenance cost is also much less.

    Opis:
    A recent development in the material studies provides beneficial application of lightweight alloys such as aluminium, magnesium as well as composites and metal matrices. The alloys are experimentally improved by increasing hardness in the ballistics testing using projectiles,makes them viable for the areas such as aerospace, military, defence, automobiles and so on. So the study is made on different approaches. First, by comparing different types of non-ferrous alloys and projectiles regarding sizes, structures. Second, the materials with heat treatment are also studied for investigating the hardness property by overcoming successful penetration on non-ferrous alloys. Third, material to be improvised by use of numerical studies such as 3D models, empirical models and software such as ANSYS, ABAQUS and AUTODYN, etc. Finally, the aim of this paper is to review the recent progress ballistic studies of lightweight materials and to provide a best choice of material for further on-going research.
