Opis:
The objective of this work was to register and document the traditional knowledge of plant resources used in ethnoveterinary practices in Kendrapara district of Odisha, India. Investigation was carried out in the interior of the district, to explore the therapeutic uses of plants by local inhabitants. Information was gathered from traditional healers, elderly people and farmers by using participant observation, open-ended conversations and semi-structured questionnaires. Plants used as veterinary medicines were collected and identified by botanical classification. Fifty five plant species, distributed among 34 families, were indicated for 27 different medicinal uses. The family Solanaceae had the largest number of reported species followed by Mimosaceae, Fabaceae and Apocynaceae. Prominent diseases treated by plant remedies were wounds, diarrhea, constipation, snake bite, skin ailments and rheumatism. Leaves were more commonly utilized for the preparation of ethnoveterinary medicine than other plant parts. Documentation of traditional knowledge related ethnoveterinary information and identification of potential species for prioritization of conservation through sustainable management is essential for the benefit of future generations. The present study contributed to the construction of an inventory of ethnoveterinary plants, which might provides a better database for future scientific validation studies.

Objective: Lepidium sativum, commonly known as chandrashoor in India, has been used in the Indian traditional medicine system for the treatment of various diseases. The present study was undertaken to investigate the hypoglycemic effect of Lepidium sativum in normal and streptozotocin-induced diabetic rats. Materials and methods: Thirty (30) adult male Wistar rats weighing 157±51g were randomly assigned to five groups of six rats each as Normal control, Diabetic control, Diabetics supplemented with Lepidium sativum extract, Diabetics treated with insulin, and Normal rats supplemented with Lepidium sativum. All rats were fed with a normal laboratory diet, nutrient rich pellets, and had free access to drinking water. The rats were injected with streptozotocin at a dose of 45 mg/kg body weight intraperitoneally to induce diabetes. The extracts were then given orally to different groups of rats at a dose of 20mg/kg body weight for 16 days. Thereafter, the rats were sacrificed, and blood samples collected by cardiac puncture were used for the determination of Glucose, Creatinine, Alkaline Phosphatase, Cholesterol, Malondialdehyde level, % DPPH, and FRAP content. Results: Administration of lepidium extract showed a significant reduction in glucose, creatinine, and alkaline phosphatase levels. Elevated cholesterol level was restored approximately to normal; a significant decrease in malondialdehyde levels was also observed compared to diabetic controls. Conclusion: Lepidium sativum extract shows efficacy in the prevention and management of diabetes mellitus and its related complications.

Background . Melanin finds enormous applications in different industries for its unique photoprotective and anti-oxidant properties. Due to its emerging demand, scientific researchers are putting efforts to unravel more microorganisms with a potential of producing melanin on large scale. Hence, the present study was aimed at the isolation of extracellular melanin producing microorganisms from lime quarries of Karnataka, India. Besides this, the tyrosinase gene governing melanin synthesis in different organisms were compared in silico to understand its evolutionary aspects. Material and methods . Melanin producing microorganisms were screened on tyrosine gelatin beef extract agar medium. Potential isolate was explored for submerged production of melanin in broth containing L-tyrosine. Melanin was characterized by UV-Vis spectroscopy, thin layer and high performance liquid chromatographic techniques. Antibacterial activity of melanin was performed by agar well assay. Comparative tyrosinase gene sequence analysis was performed by using Geneious 2021.1 trial version software. Results . Pseudomonas otitidis DDB2 was found to be potential for melanin production. No antibacterial activity was exerted by the melanin against tested pathogens. The in silico studies showed that the common central domain of tyrosinase protein sequence of selected Pseudomonas sps. exhibited 100% identity with the common central domain of Homo sapiens tyrosinase (NP_000363.1). Conclusions . Our study shows the production of melanin in good quantities by the isolate Pseudomonas otitidis DDB2 which can be explored for scale-up process. Since the melanin formed is of eumelanin type and the tyrosinase gene sequence of several Pseudomonas sp. showed relatedness to humans, this molecule may be further developed for sunscreen formulations.

Opis:
In this paper we deal with a relatively simpler method for the Fourier analysis of EXAFS data and illustrate this by a detailed analysis of the data for cobalt metal foil and cobalt complexes of isoxezol series. The Fourier analysis is useful in extracting distances and information about the phase shifts, the amplitudes, the Debye-Waller factors and the mean free paths. Here we have determined interatomic distances, mean square deviation and inelastic mean free path from the Fourier transform of EXAFS data for cobalt metal foil and cobalt complexes of isoxezol series by Math-CAD programming.

Opis:
In this paper, utility/DG interfaced DPWM solar (PV) power converter (SPC) has been proposed and developed to meet the growing green energy demand of household applications in a developing country like India. The use of new software based direct PWM strategy (DPWM) in the inverter circuit has resulted in to produce a very near sine-wave, most suitable for various home loads. Simulated results of proposed PWM output wave form and computation of its harmonics content in terms of THD value (upto 5% or even less) using MATLAB software has been reflected in the proposed scheme. The features like an intelligent control action to prevent battery from overcharge or undercharge, higher efficiency (> 90%), generation of grid quality green electricity, sustainability of solar renewable energy sources, cost effective hardware realization with FPGA based VLSI embedded system, shows the superiority of the proposed scheme over conventional power supply systems.

Opis:
Most cold rolling mills are prone to chatter problem. Chatter marks are often observed on the strip surface in cold rolling mill leading to downgrade and rejection of rolled material. Chatter impact product quality as well as productivity of mill. In absence of online chatter detection no corrective action can be taken immediately and whole campaign gets affected. Most conventional approach for online chatter detection is by using vibration measurement of mill stands in time & frequency domain. Present work proposes two approaches to detect chatter in cold rolling mill using a statistical technique called Principal Component Analysis (PCA). In this paper two methods are used for chatter detection. First method applies PCA on Fast Fourier Transform (FFT) to differentiate between chatter and non-chatter condition. Second method applies PCA on statistical parameters calculated from raw vibration data to detect chatter.

Opis:
In the present study, the effect of multiple part-through cracks on the vibration characteristics of thin isotropic rectangular plate is presented. The proposed analytical model is developed using Kirchhoff’s classical plate theory and the crack terms are formulated using the simplified Line Spring Model (LSM). The application of Berger's formulation helps to transform the derived governing equation in the form of well known Duffing equation with cubic nonlinearities and then the solution for final governing equation is obtained using Galerkin's method for two different boundary conditions. The fundamental frequency of the plate as affected by the number of cracks, cracks length, cracks orientation, and plate aspect ratio for different boundary condition is presented. It is found that the results obtained for natural frequencies are maximally affected by number of cracks, crack length and orientations.

Opis:
In the present investigation, we have studied leaching on polygrain Al-based quasicrystalline $(i-Al_{63}Cu_{25}Fe_{12})$ as well as crystalline (B2 phase; $Al_{55}Cu_{30}Fe_{15})$ alloy surfaces using a 10 mole NaOH solution. The surface was leached at varying times from 30 min to 8 h and subsequently characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy dispersive X-ray analysis. Leaching of the samples for 30 min generated a homogeneous layer. However further leaching for 1-8 h yielded nano-size particles on the surface. Spherical microstructure has been observed on the Al-Cu-Fe crystalline surface whereas on the quasicrystalline surface a petal-like microstructure appeared. The implications of the evolution of different microstructures in the context of structure, stability and activity are discussed. The results are compared with the microstructure of leached polygrained samples containing a mixture of different surface orientations.
