Fundamentos emocionales de la educación moral: aplicaciones para la práctica
Authors: Bisquerra Alzina Rafael , Buxarrais Maria Rosa , Martínez Miquel , Tey Amèlia
Published: January 2023

En este artículo se presenta un cambio de perspectiva en la educación moral que se ha producido a partir del cambio de siglo. En primer lugar, se trata la relación entre emoción y moral a lo largo de la historia, donde autores como Spinoza, Hume y Adam Smith sentaron las bases de la moral en las emociones. Con la llegada del racionalismo con Kant y después con el predominio del conductismo en psicología, las emociones pasan a ser ignoradas. En el siglo XX, la educación moral ha tenido un enfoque eminentemente cognitivo, basado en gran medida en las aportaciones de Piaget y de Kohlberg. No es hasta entrado el siglo XXI cuando se produce una revolución emocional en el estudio de la moral, cuyos representantes más significativos son Gilligan, Greene, Haidt y Prinz, entre otros. Se presentan las aportaciones de estos autores para configurar el marco de las emociones morales y sus aplicaciones a la educación emocional y moral.

Assessing and mitigating the radar–radar interference in the German C-band weather radar network
Authors: Frech Michael , Hald Cornelius , Schaper Maximilian , Lange Bertram , Rohrdantz Benjamin
Published: January 2023

Abstract. The national German weather radar network operates in C-band between 5.6 and 5.65 GHz. In a radar network, individual transmit frequencies
have to be chosen such that radar–radar-induced interferences are avoided. In a unique experiment the Hohenpeißenberg research radar and five operational systems from the radar network were used to characterize radar–radar-induced interferences as a function of the radar frequency. The results allow assessment of the possibility of adding additional C-band radars with magnetron transmitters into the existing network. Based on the experiment, at least a 15 MHz separation of the nominal radar frequency is needed to avoid a radar–radar interference. The most efficient mitigation of radar–radar interference is achieved by the “Radar Tango”, which refers to the synchronized scanning of all radar systems in the network. Based on those results, additional C-band radar systems can be added to the German weather radar network if a further improvement of the radar coverage is needed.
The State as a “form of life” and the space as Leistungsraum: the reception of Ratzel in the First and Second World Wars
Authors: Chiantera-Stutte Patricia
Published: January 2023

Abstract. My contribution explores the meaning of war and the role of Germany, which
was seen as representing a Mittellage, before the First and the Second World Wars, through the eyes of two main authors who radically reinterpreted and appropriated geographical political thinking, particularly the work of Ratzel. I am referring to the Swedish political scholar Rudolf Kjellen and the “crown jurist” of the Third Reich, Carl Schmitt. The consideration of the triple relation between space, Ratzel and war casts light on Kjellen's and Schmitt's use of Ratzel as a lever in order to promote their idea of politics and political science. Ratzel's concepts offered Kjellen and, in a different way, Schmitt, a means of justifying their way of overcoming and stretching the “limits” of their disciplines and, at the same time, of introducing a new idea of political and geographical organization, which de facto legitimized German expansion, in two crucial periods of German political life – the First and the Second World Wars. As a consequence, their Ratzel was oriented toward militant aims. Moreover, their scientific and political ideas were clearly intertwined – they explicitly rejected the idea of separating their roles as political activists and as members of a
scientific community.

Authors: M. S. Ranganath , V Vipin
Published: January 2023

This paper investigates the parameters affecting the roughness of surfaces produced in the turning process for the various materials studied by researchers. Design of experiments were conducted for the analysis of the influence of the turning parameters such as cutting speed, feed rate and depth of cut on the surface roughness. The results of the machining experiments were used to characterize the main factors affecting surface roughness by the Analysis of Variance (ANOVA) method Taguchi‟s parametric design is the effective tool for robust design it offers a simple and systematic qualitative optimal design to a relatively low cost. The Taguchi method of off-line (Engineering) quality control encompasses all stages of product/process development. However the key element for achieving high quality at low cost is Design of Experiments (DOE). In this paper Taguchi‟s (DOE) approach used by many researchers to analyze the effect of process parameters like cutting speed, feed, and depth of cut on Surface Roughness and to obtain an optimal setting of these parameters that may result in good surface finish, has been discussed.

Authors: Chopra Kapil , Sahni V. , Mishra R. S.
Published: January 2023

The utility of second law analysis on vapour compression refrigeration systems is well defined because it gives the idea for improvements in efficiency due to modifications in existing design in terms of reducing exergy destructions in the components. Due to effect of global warming and ozone depletion the comparison and impact of environmental friendly refrigerants (R507a, R410a, R290, R600, R600a, R1234yf, R404a, R125, R717, R152a and R407C) on multiple evaporators at different temperature with compound compression and flash intercooler with individual and multiple throttle valves is important for calculating first law and second law performance on the basis of energetic and exergetic approach. Comparison was done for multiple evaporators with compound compression and flash intercooler with individual throttle valves (system-1) and multiple evaporators with compound compression and flash intercooler with multiple throttle valves (system-2) in terms of coefficient of performance, rational efficiency and total system defect. It was observed that for all considered refrigerants second law first law efficiency of system-1 is lower than sytem-2 conversely system defect of system-1 is higher than system-2.In terms of energetic efficiency, rational efficiency and system defect for both systemsR407C shows minimum performance and performances of R600, R152a and R717 better with comparison of other selected refrigerants for system-1 and system-2. But R600 is highly inflammable and R717 is toxic in nature and restricted to limited applications, so R152a is suggested for both systems.

Published: January 2023

To facilitate more extensive adoption of renewable distributed electric generation, the U.S. Department of Energy launched the Renewable Systems Interconnection (RSI) study during the spring of 2007. The study addressed the technical and analytical challenges that must be addressed to enable high penetration levels of distributed renewable energy technologies. Interest in PV systems is increasing and the installation of large PV systems or large groups of PV systems that are interactive with the utility grid is accelerating, so the compatibility of higher levels of distributed generation needs to be ensured and the grid infrastructure protected. The variability and non dispatch ability of today’s PV systems affect the stability of the utility grid and the economics of the PV and energy distribution systems. Integration issues need to be addressed from the distributed PV system side and from the utility side. Advanced inverter, controller, and interconnection technology development must produce hardware that allows PV to operate safely with the utility and act as a grid resource that provides benefits to both the grid and the owner.

Authors: Gill Kanwar Jabar Singh , Swaich Avneet Singh
Published: January 2023

Many attempts to use vegetable oils as fuel have been performed since the early days of the Diesel engine. When a Diesel engine is used with vegetable oil fuel for a short period of time, the performance and global efficiency are usually very close to Diesel fuel. However, during long-term engine tests with vegetable oils as fuel, heavy deposits build-up can be observed in the combustion chamber. These deposits can lead to engine breaks. A fuel droplet vaporization experiment proved that the deposits build-up is mainly controlled by the combustion chamber temperature. A new thermally insulated combustion chamber made it possible to raise the combustion chamber wall temperature. With this combustion chamber, the deposits were greatly reduced. To use vegetable oils as fuel, DI Diesel engines need to be redesigned to accommodate the specificity of the vegetable oils combustion, one possibility is to use a thermally insulated combustion chamber. This paper is related with performance analysis of Compression Ignition Engine using sunflower oil for different engine load from 1 kg to 10 kg and different portmanteau ratios like Portmanteau:1000, Portmanteau:7525, Portmanteau:5050, Portmanteau: 2575, and Portmanteau:0010. With the injection of above Portmanteau in different portmanteau ratio and at different load we found the exhaust emission in terms of CO emission, HC emission, Exhaust gas temperature and smoke density and performance analysis of the bio-fuel.

Published: January 2023

Metal determination in human tissues is the most common application of biological monitoring for screening, diagnosis and assessment of metal exposures and their risks. Humans and other living organisms are exposed to a variety of chemical pollutants that are released into the environment as a consequence of anthropogenic activities. Environmental pollutants are incorporated into the organism by different routes and can then be stored and distributed in different tissues, which leads to an internal concentration that can induce different alterations, adverse effects and/or diseases. Control measures should be taken to avoid these effects and human biomonitoring is very useful tool that can contribute to this aim. This paper deals with the quantitative determination of Fe, Pb, Ni, and Zn concentrations in fingernails of male subjects from various locations i.e., from industrial, commercial, urban, and rural areas. The levels of these metals were assayed by AAS. Studied metal concentrations in fingernails were in the order Fe > Zn ≥ Ni > Pb. This study proved that human fingernails could be used as a biological indicator for the assessment of heavy metal pollution.

Advanced Optimization of Fundamental Searching and Sorting Algorithms
Authors: Singh Jasrat
Published: January 2023

Searching and Sorting are the most important data structure operations, which make easy searching, arranging and locating the information. One of the basic problems of computer science is sorting a list of items and searching elements in the array. There are a number of solutions to these problems, known as sorting algorithm, and searching algorithm. Some searching algorithms are simple and spontaneous, such as the Linear Search, Binary Search. All searching algorithms are problem specific meaning they work well on some specific problem and do not work well for all the problems, therefore, appropriate for specific kinds of problems. Some searching algorithm works on less number of elements. There are some fundamental sorting algorithms as Selection Sort, Insertion Sort, Quick Sort, Merge Sort, Bubble Sort etc. After studying various sorting and searching algorithms we found that the algorithms can be optimised. This paper presents a new searching algorithms named as “OBSwQS” is designed to perform searching quickly and more effectively as compared to the existing version of searching algorithm in which there are used the concepts of Binary Search and Quick Sort algorithms, and the optimised sorting algorithms as “DNSS”, “DNBS”, “Insertion Sort within the Merge Sort” and etc. are the optimised sorting algorithm which are the optimization of Fundamental Selection Sort, Bubble Sort, Merge Sort and etc. The introduction of Dual Nature Selection Sort and Dual Nature Bubble Sort version of selection sort algorithm and Bubble Sort for sorting the data stored in database instead of existing selection sort algorithm and Bubble Sort algorithm will provide an opportunity to the users to save almost 50% of their operation time with almost 100% accuracy. In “Insertion Sort within the Merge Sort algorithm” there is found out the value of maximum value of n ( n is number of items to be sorted) so that the insertion sort beats the merge sort. Hence the “ISwMS” is optimization of Fundamental Merge Sort algorithm.
Adoptive Cloud Application in Semantic Web
Authors: Arya Mukesh Kumar , Gupta Namit
Published: January 2023

Cloud computing has been envisioned as the next-generation architecture of IT enterprise. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. This unique attribute, however, poses many new security challenges which have not been well understood. In this article, we focus on cloud data storage security, which has always been an important aspect of quality of service. To ensure the correctness of users' data in the cloud, we propose an effective and flexible distributed scheme with two salient features, opposing to its predecessors. By utilizing the homomorphic token with distributed verification of erasure-coded data, our scheme achieves the integration of storage correctness insurance and data error localization, i.e., the identification of misbehaving server (s). Unlike most prior works, the new scheme further supports secure and efficient dynamic operations on data blocks, including: data update, delete and append. Extensive security and performance analysis shows that the proposed scheme is highly efficient and resilient against Byzantine failure, malicious data modification attack, and even server colluding attacks.

Published: January 2023

This paper presents thermodynamic performance evaluation of gas turbine co-generation with alternative regeneration system in comparison to simple and conventional regenerative cogeneration systems. The energetic and exergetic efficiencies have been defined. The effects of pinch point temperature (PPT) and process steam pressure used in have been investigated. For higher TITs the second law efficiency and power to heat ratio is relatively higher for alternative regeneration with cogeneration system. It is observed from the results obtained that power to heat ratio increases with increase in pinch point but first and second law efficiency decreases with an increase in pinch point. Power to heat ratio increases significantly with increase in process steam pressure but first law efficiency decreases with the same. The second law efficiency increases with increase in process steam pressure up to 1 MPa and afterwards decreases with increase in process steam pressure. Results also show that inclusion of cogeneration with alternate regeneration provides significant improvement in process heat production and second law efficiency.

Air-conditioning is one of the major consumers of electrical energy in many parts of the world today and already today air-conditioning causes energy shortage in for example China. The demand can be expected to increase because of changing working times, increased comfort expectations and global warming. Air-conditioning systems in use are most often built around a vapour compression system driven by grid-electricity. However, most ways of generating the electricity today, as well as the refrigerants being used in traditional vapour compression systems, have negative impact on the environment. Solar air-conditioning might be a way to reduce the demand for electricity. In addition many solar air-conditioning systems are constructed in ways that eliminate the need for CFC, HCFC or HFC refrigerants. This research work is based on the Peltier effect with which we can cool a specific area without using compressor which take a huge consumption of electricity. And this system is driven by solar energy using solar plates, battery, transformer peltier module and heat sink. This paper deals with a wide range of components, from room air-conditioners to solar.Conventional compressor run cooling devices have many drawbacks pertaining to energy efficiency and the use of CFC refrigerants. Both these factors indirectly point to the impending scenario of global warming. As most of the electricity generation relies on the coal power plants, which add greenhouse gases to the atmosphere is the major cause of global warming. Although researches are going on, better alternatives for the CFC refrigerants is still on the hunt. So instead of using conventional air conditioning systems, other products which can efficiently cool a person are to be devised. By using other efficient cooling mechanisms we can save the electricity bills and also control the greenhouse gases that are currently released into the atmosphere .Air-conditioning is one of the major. Collectors, which can be used as subcomponents in a solar air-conditioning system. However, most of the components and subsystems covered are not only suitable for solar air-conditioning. Some components are used for electrically, mechanically or heat driven air-conditioning. And of course other sources of mechanical energy or heat could be used for powering these components. Other components are used for solar energy collection and storage, which can be used in solar energy system with other purposes than just driving a solar air-conditioning system. In this research work the idea was to build an alternative for AC and to provide Air conditioning effect. The research aims to design and build a miniature prototype of thermoelectric cooling system for a conventional air conditioned to provide air conditioning to reduce the consumption of electricity and to reduce the pollution.

Published: January 2023

The aim of this simulation work is to study effect of channel doping concentration. The channel lies under the oxide layer of the MOSFET. The results obtained show that as channel doping concentration decreases threshold voltage decreases and good saturation region in I-V curve is obtained and the drain current increases. So the lower channel doping concentration provides better mobility and hence, less velocity saturation.

Surface texture is influenced by the machining, cutting parameters. The MOTIF-method is a system for the evaluation of the primary profile and based on the envelope system and is suitable as an alternative to the mean line system. The MOTIF-method determines the upper points of the surface profile, which have an importance for the functional behavior. Roughness and waviness can be evaluated directly based on the diagram of the unfiltered profile. The effects of cutting speed, feed rate and depth of cut on surface texture analysis have been studied. The experiments were conducted to study the effect of machining parameters on turning of mild steel. The total set of experiments carried out is 27. The specimen was turned under different levels and R, Rx and Ar values were analysed. Results obtained concluded that the Feed rate is the significant factor.

There are two primary device structures that have being widely used. One is the bulk structure, where a transistor is directly fabricated on the semiconductor substrate. The other one is called SOI (silicon-on-insulator), where a transistor is built on a thin silicon layer, which is separated from the substrate by a layer of insulator or device scaling; it is basically try to balance two things: device functionality and device reliability. Both of them have to be maintained at a smaller dimensional size [1]. In this paper, three transistors are proposed having different channel lengths 8 micron, 16 micron and 24 micron. Simulation shows that with a fixed gate length, when channel length is increased, the output characteristics slope is decreased.
