Opis:
The present paper deals with an EOQ model for deteriorating items with time-dependent exponential demand rate and partial backlogging. Shortages are allowed and completely backlogged in this model. The backlogging rate of unsatisfied demand is assumed as a function of waiting time. The concept of penalty cost is introduced in the proposed model because there are many perishable products that do not deteriorate for some period of time and after that period they continuously deteriorate and lose their values. This loss can be incurred as penalty cost to the wholesalers/retailers. In any business organization, the penalty cost has an important role for special types of seasonal products and short life products. Therefore, the total cost of the product can be reduced by maximizing the demand rate and minimizing the penalty cost during a given period of time. The purpose of our study is to optimise the total variable inventory cost. A numerical example is also given to show the applicability of the developed model.

Opis:
Given India’s vibrant religious landscape, there is a somewhat surprising paucity of depart‐ ments, centres or even programs for the academic study of religion. This article discusses this issue based on the preliminary results of an interview study conducted at Banaras Hindu University (BHU), Varanasi, India, in 2014 and 20 Its focus is on the views of university teachers and researchers concerning the place, role and function of religion and religious stud‐ ies at BHU. Twenty‐eight semi‐structured interviews were conducted. In the course of their analysis, six themes emerged: 1) the place and role of religion in society; 2) religion as ‘religi‐ osity/spirituality’ or sanatana dharma vs. political ideology/communitarianism; 3) religion vs. dharma; 4) secularization; 5) religion in education in general; and, 6) religion in the education at BHU. The informants agreed on the increasing importance of religion in India, and most of them viewed the meaning of secularization as being ‘equal respect for all religions’. Moreover, a majority distinguished between ‘religion’, in the Western sense, and the Indian conception of dharma, considering it regrettable that the latter, described as the common ground of all reli‐ gions, is not taught more extensively at BHU. They also considered the original ideal of BHU’s founder, Madan Mohan Malaviya, to be of signi cant importance. That ideal involved not only teaching students the knowledge and skill sets found in a standard modern university, but also equipping them with a value‐based education, grounded upon sanatana‐dharma. As our project progresses, further understanding of this turn toward dharma education is something we intend to pursue through the lens of multiple modernities, developed by Marian Burchardt et al. as multiple secularities.

Opis:
Wireless Sensor Networks have played a great role in various application domains like environmental tracking for precision agriculture, structural health monitoring, patient health monitoring, intrusion detection, earthquake or volcano prediction and industrial monitoring etc. The major design issues to be dealt in Wireless sensor networks (WSNs) are its resource constraint nature, limited network lifetime and scalability. The most stringent of all is energy consumption and battery life which actually limits the network lifetime. This paper presents various energy aware location based routing protocols and in depth comparison based on various characteristics such as routing selection method, data aggregation, routing metrics, periodic message type, scalability, energy efficiency, robustness, event/query based and strengths.

Opis:
Detection of the range of a target using laser range finders requires filtering of incoming data in real-time which can be achieved by a dedicated hardware to meet demanding time requirements. In this paper efficient filter structure which is the combination of constant false alarm rate (CFAR) and pipelined least mean square (LMS) adaptive filtering technique used to create solution for various adaptive filtering problems. Cell averaging (CA) CFAR and automatic censored cell averaging (ACCA) CFAR algorithm are fused separately with the adaptive filter in order to filter the incoming signal so that the detection of the of a target can be achieved through peak detection unit and accordingly range can be calculated. The design with CA-CFAR fused with PLMS filter is synthesized and implemented on a Xilinx Virtex4 FPGA with 32 MHz clock using Xilinx ISE software. Other design with ACCA-CFAR combined with PLMS filter is modeled and simulated in MATLAB simulink.

Opis:
In this new era, we are facing a major problem regarding wastewater in the environment, which has an adverse effect on human life. Wastewater from tanning industries is one of the major contributors to the pollution in aquatic systems. Tannery industries have always contributed to the world’s economy and trade despite facing criticism due to environmental pollution. Tanning effluent consists of organic, inorganic (chromium, nitrogenous compounds), and a large amount of solid content like TDS, TSS, TVS. To overcome these significant challenges, there have been few advancements related to tannery wastewater treatment. This article aims to provide a brief review on electrocaogulation based treatment technologies for eliminating the impurities from tannery wastewater. This review consists of the background with characteristics of tannery wastewater, the alternatives for treating the tannery effluent over the years along. A detailed description of the advanced technologies based on electrocoagulations is implemented to overcome the drawbacks of the existing methods.

Opis:
An axial flow tubular heat exchanger has been experimentally investigated to augment the heat transfer rate with a novel swirl flow of air past the heated tubes. The novel design has been based on circular baffle plates provided with trapezoidal air deflectors of various inclination angles. The arrangement of tubes is kept the same throughout the experiment, in accordance with the longitudinal airflow direction. The tubes maintained a constant heat flux condition over the surface. Four deflectors with equal inclination angles were developed on each baffle plate, generating air swirl inside a circular duct carrying the heated tubes that increase air-side turbulence and, consequently, the surface heat transfer rate. The baffle plates were placed equidistant from each other at variable pitch ratios. The Reynolds number was kept in the range of 16000– 28000. The effect of pitch ratios and inclination angles on the thermo-fluid performance of the heat exchanger was studied. The investigations revealed an average improvement of 3.75 times in thermo-fluid performance for an exchanger with a deflector baffle plate with a baffle inclination angle of 50_ and a pitch ratio of 1.4 when compared to other inclination angles and pitch ratios.

Opis:
Three different carbon paste (CP), silk-screen (SP) and poly (vinyl chloride) (PVC) modified electrodes were obtained to verify the reliability of AVELOX, the generic name of which is Moxifloxacin HCl (AV-MOXH). The sensing membranes were containing AVELOX ion associated complexes with sodium tetraphenylborate (NaTPB), phosphomolybdic acid (PMA), phosphotungstic acid (PTA), and ammonium reineckate (RN) as electroactive materials. All three electrodes gave fast, viable, and near-Nernstian linear responses over a relative wide concentration range that ranged from 1.010-6 to 1.010-2 mol/L AV-MOXH at 25°C with a monovalent cationic decrease. The sensors demonstrated a good discernment of AV-MOXH from numerous inorganic and organic compounds such as glucose, sucrose, Na+, Ca+, etc. Additionally, the isothermal coefficients along with selectivity coefficients were calculated. The modified Screen Printed Electrode sensor appeared to be highly sensitive for the determination of AV-MOXH. The electrode response was observed in pH range 2–6 for ISPE electrodes and IPVC electrodes and 3–7 for ICPE electrodes under various temperature conditions. The short response time, lifetime validity, recovery, and all the methods of validation such as limit of detection and limit of quantification were estimated. The potentiometric method turned out to be suitable for determining AV-MOXH in pharmacological formulations, and the findings obtained are comparable to the “HPLC official method” in terms of the agreement. As a result, the postulated potentiometric approach was verified in accordance with IUPAC guidelines.
Otrzymano trzy różne elektrody modyfikowane pastą węglową (CP), sitodrukiem (SP) i polichlorkiem winylu (PVC), w celu oceny skuteczności działania leku AVELOX (nazwa rodzajowa Moxifloxacin HCl, AV-MOXH). Membrany czujników zawierały kompleksy jonu AVELOX z tetrafenyloboranem sodu (NaTPB), kwasem fosfomolibdenowym (PMA), kwasem fosfowolframowym (PTA) i soli Reineckego (RN) jako materiałami elektroaktywnymi. Wszystkie trzy elektrody dały szybkie i bliskie zależności liniowe Nernsta w zakresie stężeń AV-MOXH od 1.0-10-6 do 1.0-10-2 mol/l (w 25°C). Elektrody wykazały dobrą selektywność w oznaczaniu AV-MOXH względem wielu jonów i związków organicznych i nieorganicznych, jak glukoza, sacharoza, Na+, Ca+ itp. Dodatkowo obliczono współczynniki izotermiczne oraz współczynniki selektywności. Zmodyfikowany czujnik z elektrodą sitodrukową okazał się być bardzo czuły do oznaczania AV-MOXH. Badania prowadzono w zakresie pH 2–6 w przypadku elektrod ISPE i IPVC oraz 3–7 w przypadku elektrod ICPE w różnych temperaturach. Oszacowano czas odpowiedzi elektrod, ich czas życia, możliwość regeneracji, odzysk oraz granicę wykrywalności i granicę oznaczalności. Metoda potencjometryczna okazała się być odpowiednia do oznaczania AV-MOXH w preparatach farmakologicznych, a uzyskane wyniki są porównywalne z „oficjalną metodą HPLC”.

Opis:
The numerical study of two-dimensional laminar thermo-diffusion natural convection in an exponentially heated and concentrated square enclosure of unit length in the presence of a uniform horizontal magnetic field is presented in this paper. The left and right vertical walls are assumed to have higher and lower temperatures and concentrations, respectively, and are governed by exponential functions, whereas the horizontal walls are assumed to be adiabatic and non-diffusive. The mathematical formulation of heat and mass functions has been completed, and heat and mass line contours have been drawn based on these functions to investigate the behavior of heat and mass in the cavity. The flow governing equations were solved using a finite difference method in conjunction with the Successive Over-Relaxation (SOR) technique and then converted to a vorticity-stream function form. A detailed comparison of isotherms with heatlines and isosolutes with masslines has been performed. Furthermore, the reduction for lower Rayleigh numbers Ra surpassing the reduction for higher values of Ra. The maximum reduction in overall heat and mass transfer has been observed for higher Hartmann (Ha = 8).
