Abstract: In paper fundamental problems of internal gravity waves dynamics are considered. The solution of this problem is expressed in terms of the Green’s function and the asymptotic representations of the solutions are considered. The uniform asymptotic forms of the internal gravity waves in horizontally inhomogeneous and non-stationary stratified ocean are obtained. A modified spatio-temporal ray method is proposed, which belongs to the class of geometrical optics methods (WKBJ method). Analytical and numerical algorithms of internal gravity wave calculations for the real ocean parameters are presented.

Abstract: Storage experiments were conducted under ordinary room conditions in the mid hill, Khumaltar (1350 masl ; meter above sea level) and high hills, Daman (2200 masl) of Nepal during the summer season of 2011 to find out the effect of chemical treatments and their time of applications on storability and chips qualities of potato cv. Kufri Jyoti. Chemicals treatments were; CIPC (Isopropyl N (3 chlorophenyl) carbamate), hydrogen peroxide and calcium chloride, which were applied as a single dose (before storage) and double dose (before and at 45 days in storage). Ordinary water treated potatoes served as control. The treatments were replicated thrice. Apparently healthy tubers > 60 gram weight after different chemical treatments were stored in bamboo racks and wooden tray, respectively at Kumaltar and Daman for 120 days.

Abstract: Surface functionalization of gold nanoparticles is theoretically investigated in order to develop physical antibiotics coping with antibiotic-resistant bacteria. The core concept of the physical antibiotics is based on the design strategy utilizing molecular elements in peptidoglycan for surface functionalization of gold nanoparticles. These gold nanoparticles will couple to peptidoglycan easily during the proliferation or growth of the bacteria, leading to the destruction of cell walls. Additionally, physical fields (electromagnetic wave, X-ray or ultrasound) bring enhanced suppression of the proliferation. This strategy allows us to have wide variety of antibiotics designs and the suppression against the outbreak of antibiotic-resistant bacteria.

Abstract: The article discussed the selected methods of measurement systems analysis (MSA) in case of different devices usage. Analysis of variance is a common method, widely accepted and applied in industry to analyze measurement systems by taking into consideration different sources of variability: equipment, operators, parts and their interaction. Regression is a method which could simplify the analysis by shortening its time and decreasing sample size. It also may enable more clear and suitable answer. The included case study concerning two coordinate measuring machines (CMM) indicates the usefulness of the regression as a method for high precision and automated measurement systems comparison. Some actions resulting from the inferences can be undertaken by managers and engineers in industrial enterprises to reduce the cost of double measurements.

Abstract: We discuss the problem of splitting a given geometrical plane figure in two regions of equal area by drawing a line through a given point in the plane. We also discuss the possibility of splitting the figure into regions in proportions p% and (1 − p)% of the area of the given figure.

Abstract: This study examined the affective and cognitive benefits of taking photographs of one’s everyday surroundings. Thirty-eight undergraduate participants were randomly assigned to either take photographs in a mindful, creative way; take photographs in a neutral, factual way; or do a count-your-blessings writing exercise, an activity that is known to reliably increase mood [1]. Planned contrasts revealed that those taking mindful, creative photographs were, on average, in a significantly better mood and were significantly more appreciative and motivated than those taking neutral photographs. There were no significant differences between either photography condition and the writing activity. These results suggest that, when done thoughtfully, photography can be an effective way of improving mood and appreciation of everyday life.
