Cuando se incrementan las conductas antisociales y emergen los conflictos, aparte de medidas coyunturales -de acuerdo con protocolos- que haya que tomar, la respuesta educativa no puede ser qué hacemos para enfrentarnos a ellos; sino -precisamente porque estamos en centros “educativos”- cómo convertir nuestras escuelas en espacios adecuados para el aprendizaje de la convivencia y el desarrollo moral-cívico de los ciudadanos. Estos comportamientos antisociales deben ser ocasión propicia para el aprendizaje de la convivencia, que incluye (aunque no sólo) su corrección. En lugar de cualquier propuesta sancionadora, se requiere un discurso y unas propuestas educativas para la mejora de la convivencia. El reto de la convivencia escolar se ha de abordar sumando acciones positivas y proactivas. Esta es la tesis que defiende el libro que reseñamos y compartimos ...

Published: April 2023

A mixed area is one area that requires pedestrian path due to the commercial and non-commercial functions that are close to each other. Traveling short distances on foot will be more effective than using a vehicle because it is impossible to always stop at the desired location. One of the mixed-use areas with high mobility in Bandar Lampung is the Zainal Abidin Pagar Alam Mixed Area, Bandar Lampung City. The Zainal Abidin Pagar Alam Mixed Area does not meet the standards in fulfilling pedestrian path facilities. This is indicated by the fact that there are still many roads in this area with no pedestrian path. The condition compels pedestrian to pass through the road, thus increasing the risk of accidents. This study aims to identify the need and availability of pedestrian path in the Zainal Abidin Pagar Alam Mixed Area, based on pedestrian path' quantity, and distribution. This research employs a quantitative deductive method by placing theoretical analysis as the determination of the variable, and the population of this region using a census, namely all road corridors in the Region A mixture of Zainal Abidin Pagar Alam  The results show that the quantity, and distribution, have not met the availability of pedestrian path based on PUPR Guidelines Standard No. 02 of 2018 on pedestrian Facility Planning.

Swarna (MTU7029), an Indian mega-variety of rice, is cultivated on an estimated 8Mha of land. There is a pressing need to address yield stagnation and wider adaptability to irrigated lowland and rainfed ecologies as a result of the negative consequences of climate change and population growth. The present study was aimed at improving Swarna for two yield-related traits through marker-assisted backcross breeding strategy by introgression of OsSPL14 (panicle branching) and SCM2 (stronger culm). Foreground and background selection was carried out at each generation. Homozygous BC2F2 plants harbouring both yield-enhancing genes were identified and advanced through pedigree selection till BC2F5 and evaluated in station trials. Three promising lines possessing higher yield over recurrent parent were identified, and a single line, IET 27661 exhibited superior yield in multi-location trials of the All India Coordinated Rice Improvement Programme (AICRIP) and was found to be promising.
Effect of different nutrient management practices on nutrient availability and uptake in Vaikom kari soils of Kuttanad, Kerala
Authors: VS Devi
Published: April 2023

A field experiment was laid out in RBD with 16 treatments in three replications with rice variety Uma. The treatments were dolomite, lime + MgSO4 or Rice Husk Ash (RHA) + MgSO4 along with 100% package of practice recommendations of Kerala Agricultural University (POP) alone or with 100% POP + foliar spray of 13:0:45 (1%) or borax (0.5%) or 13:0:45 + borax at PI stage. Lime + MgSO4 + 75% POP + 13:0:45 + borax as well as lime without MgSO4 + 100% POP combined with 13:0:45 or borax or both were also included as treatments. The treatment dolomite + POP + 13:0:45 produced the highest grain yield of 5.42 and 5.57 t ha-1 during 2015 and 2016 respectively. This treatment was followed by dolomite + POP + 13:0:45 + borax and lime + POP + MgSO4 + 13:0:45 during both the years. Lower yields were produced by the treatments involving RHA and 75% POP. The pooled analysis of two years' data also proved the significance of the treatments involving dolomite + POP or lime + POP + MgSO4 on grain yield. The highest yield of 5.49 t ha-1 was recorded by dolomite + POP + 13:0:45 followed by dolomite + POP + 13:0:45 + borax and lime + MgSO4 + POP + 13:0:45. The treatments involving RHA and 75% POP registered significantly lower grain yield in the pooled data. The treatments involving dolomite registered lower status of soil available Fe and higher status of available Mn and B. Higher status of available Zn was registered by the treatments involving dolomite or lime + MgSO4. The treatments involving dolomite, lime + MgSO4 or RHA + MgSO4 along with POP registered higher available Cu in the soil. Dolomite treatments recorded lower status of Na and exchangeable Al in the soil. Dolomite or lime + MgSO4 along with POP + 13:0:45 with or without borax registered higher uptake of Fe, Mn and Zn while dolomite + POP + 13:0:45 with or without borax recorded higher uptake of Cu and B. The treatments involving RHA and 75% POP recorded lower uptake of micronutrients during both the years. Uptake of Na was the highest with RHA + POP + MgSO4 + 13:0:45 during first year and with dolomite + POP during second year. Higher Al uptake was observed with lime + POP + 13:0:45 with or without MgSO4. The grain yield was significantly and positively correlated with the uptake of Mn, Zn, Cu and B and significantly and negatively correlated with Fe during the first year. During the second year, the yield was significantly and positively correlated with uptake of nutrients except Na and Al. The results indicated that amelioration of soil acidity is a crucial management practice for improving the availability and uptake of nutrients resulting in higher yield.
Principal component and cluster analyses for assessing agro-morphological diversity in rice
Authors: Sar Puranjoy , Kole Paresh Chandra
Published: April 2023

Forty-five rice genotypes were evaluated for determining the pattern of variation and relationship among 14 yield contributing traits. Four principal components (PCs) exhibited eigen values >1.0 and explained about 79.5 % of the total phenotypic variability. From rotated component matrix it has been observed that the highest positive eigen vector was taken by secondary branches (0.945), followed by total spikelet number (0.945), fertile spikelet number (0.889), primary branches (0.676) and harvest index (0.632) in PC1, indicating the major effects in the overall variation among the genotypes. Seven groups were formed after cluster analysis. Cluster I had lowest average for days to 50% flowering, Cluster II had highest mean value for harvest index, Cluster III had highest mean for flag leaf area, test weight, and straw and grain yield per plant, and Cluster V had highest mean value for primary branches, total spikelet number, fertile spikelet number and fertility %. So, desirable genotypes fromdifferent cluster can be selected and hybridization programme may be initiated to utilize heterosis in F1 generation and wide spectrum of recombinants in segregating generations for selection of promising segregants.

Published: April 2023

Rhizoctonia solani Kuhn (AG 1-IA) is one of the most devastating pathogens of rice causing sheath blight disease and being a prime reason for the unsatisfactory productivity of rice in India. The goal of the present study was to investigate the efficacy of silver nanoparticles (AgNPs) synthesized using an agriculturally important bacterium, Pseudomonas fluorescens OKC, in managing the sheath blight disease of rice. Successful biosynthesis of AgNPs was monitored by UV-visible spectroscopy, showing a peak at 432 nm. The AgNPs were further characterized using a Transmission Electron Microscope (TEM), Dynamic Light Scattering (DLS) and Fourier Transform Infrared spectroscopy (FT-IR). The TEM result confirmed that the size of the synthesized nanoparticles was less than 100nm. DLS results revealed that the average particle size of the AgNPs was 74 nm and the zeta potential was -23.6 mV, indicating that the synthesized nanoparticles were of good stability at room temperature. The antifungal potential of AgNPs was tested against the test fungus in vitro and maximum growth inhibition was recorded in AgNPs treatment (69.09%) as compared to the control. Moreover, this result was further authenticated under net house conditions, where AgNPs successfully reduced the incidence of R.solani Kuhn. The findings showed that the biosynthesized AgNPs inhibited the growth of R. solani Kuhn and could be useful in the management of sheath blight disease in rice.

Multi-User Reconfigurable Intelligent Surface-Aided Communications Under Discrete Phase Shifts
Authors: Jiang Wei , Schotten Hans Dieter
Published: April 2023

Reconfigurable intelligent surface a.k.a intelligent reflecting surface (IRS) has recently drawn considerable attention because of its potential to achieve high spectral and energy efficiencies in a cost-effective way. Due to its disruptive ability to manipulate wireless environments, IRS imposes fundamental particularities on multi-user communications. 

This paper focuses on studying  orthogonal and non-orthogonal multiple access in IRS-aided systems. Unlike most prior works assuming continuous phase shifts, we employ the practical setup where only a finite number of discrete phase shifts are available. To maximize the sum rate, active beamforming and discrete reflection need to be jointly optimized. We therefore propose an alternative optimization method to get the optimal continuous phase shifts iteratively, and then quantize each phase shift to its nearest discrete value. The sum-rate maximization of different schemes is theoretically analyzed and numerically evaluated with different numbers of phase-control bits.

Authors: Salih Yousif Abdulmuhsin
Published: April 2023

Background: Hemophilia is a coagulation disorder arising of a genetic defect of the X chromosome; the defect can either be inherited or result in spontaneous gene mutation. In each type of hemophilia (A, B, and C), a critical coagulation protein is missing, causing individuals to bleed for long periods of time before clotting occurs.
Objectives: 1-Assess the pediatric nurses' knowledge toward hemophilia in children. 2-Find out the factors that affecting the knowledge of the sample. Subjects and methods A descriptive study was conducted on pediatric nurses who were dealing with the children who have hemophilia, carried out in Kirkuk Governorate / teaching hospitals starting in July / 2012 to September 2013 .
Results: Based on the results the researcher found that Most of study sample (78%) is males and (42%) at age between (31 and more ) years old. Most of the nurses (60%) graduated of nursing institute and around (38% ) of them have (1-5) years of experiences in their job as a nurse while (42%) of them have (1-5)years of experiences in blood diseases wards. The (68%) of the sample had no opportunity to be involved in training courses.
Conclusion: the study indicated that the nurses have high rates of acceptable level in knowledge related to definition, type of hemophilia, the hereditary role in the transmission of hemophilia and treatment process of the disease the finding showed that the nurses have a unacceptable level in the knowledge, regarding the type of bleeding in hemophilia is internal and external, place of internal bleeding, the incidence of hemophilia in the families don't have history of the disease, types, other names of hemophilia B, the samples information about genetic roles for males and females to be incidence with hemophilia and the clotting process with the role of factors VIII , IX And these results have a bad effect on quality of care which provided for the pediatric patient. The result of the study found that most of the sample have uncertain information regarding the effect of hemophilia through bleeding on the life style of the carriers and the main complication to replacement therapy is the antibodies respectively.
Recommendations: Special training courses should be designed and constructed for nurses in relation to hemophilia. Nurse in hematological units must take their opportunity for continuing education. Increasing the number of professional nurses assigned to work in the pediatric and blood disease wards. Motivate the nurses to improve their knowledge and practices which help improve their performance with the patients. Providing scientific booklet, publication and journal about hemophilia in nursing educational program.

Published: April 2023

Cardiac myxomas constitute the most frequent forms of primitive and benign heart tumors. The left atrial location is by far the most frequent. The variability of their clinical symptomatology is related to size, mobility and location of the mass. Their diagnosis is first and foremost echocardiographic. This pathology has an increased risk of sudden death and thromboembolic complications therefore requiring early surgical management. We report the case of a 38-year-old patient with a dyspnea Stade III NYHA whose clinical examination objectified a breath of mitral narrowing. Echocardiography made possible the diagnosis of left atrium myxoma with the beginning of entrapment in the mitral valve histologically confirmed after an urgent surgical resection. The patient presented a complete AVB successfully set right after surgery. Cardiac myxomas are pathologies with serious complications involving patient’s life and functional prognosis. Conduction disorders are part of the rhythmic complications encountered in post-operative state.

Luther’s Understanding of the Presence of God in Creation: Toward a Lutheran Eco-Theology
Authors: Sihombing Hesron
Published: April 2023

This paper argues for a Lutheran eco-theology based on the notion of the presence of God in the creation, heavily derived from two of Martin Luther’s interrelated concepts: creation and sacramental theology. Both Luther’s theological ideas proclaim the presence of God based on God’s creative works. This paper investigates both theological ideas despite having different approaches to presenting God’s power and its significance to eco-theology. The method employs theoretical research of Martin Luther’s main writings and works. The primary result of this investigation shows that Luther’s understanding of the real presence of God in the dialectical differences between creation and sacramental theology provides meaningful expressions and elements to develop a Lutheran eco-theology. The paper concludes that in the middle of the present ecological catastrophe, it is urgent to develop a relevant eco-theology that can provide significant theological and ethical ideas for the care of the Earth.

Published: April 2023

Level of plastic deformations is calculated in multilayer acr welding and surfacing. The equations of compatibility of displacements caused by heating of the metal during successive application of rollers are solved. It is revealed that in the case of successive surfacing of beads and a change in the distribution of limiting temperatures, a complex pattern of the stress state of the metal arises in the zone of surfacing. This indicates the need to take into account this phenomenon in multilayer welding and surfacing in engineering practice.

Authors: Nwokoma Esomchi U. , Ijeh Boniface I. , Amos-Uhegbu Chukwunenyoke
Published: April 2023

The key factor in a successful oil field development plan is understanding the reservoir. The effectiveness of oil extraction is determined by variations in the reservoir, specifically the distribution of porosity and permeability. To create an accurate model of the reservoir, the vertical distribution of its qualities must be determined and separated into flow units, each with its own unique characteristics that affect fluid flow. By identifying these flow units, the preferred flow zones can be discovered. The aim of this study is to identify the number and distribution of hydraulic units, their important characteristics, and the flow performance in two specific wells in the Niger Delta, Nigeria, using the Modified Lorenz Plot (MLP) method. In the hydrocarbon-rich intervals of the wells, a total of 18 flow units were found, with 12 in Well 1 and 6 in Well 2. The number of flow units indicates the level of heterogeneity in the reservoir. This study showed that the Modified Lorenz Plot (MLP) is an efficient and low-cost method for defining petrophysical flow units. This research study aims to transform the conventional approach to reservoir characterization by conducting a thorough analysis of hydraulic flow units in sandstone reservoirs located in the complex geological setting of the Niger Delta, Nigeria. By examining the hydraulic properties of reservoir rocks, the study seeks to gain a better understanding of subsurface fluid flow behavior and the potential for hydrocarbon accumulation.
The influence of solvents on the appearance of the absorption bands of the polystyrene films deposited from solutions on metal mirrors
Authors: Șerban Sorina Gabriela , Strugariu Laura Maria , Jitian Simion
Published: April 2023

Infrared reflection-absorption spectra (IRRAS) at the near-normal incidence of polystyrene films from benzene, toluene, and chloroform solutions were analyzed in this paper. The appearance of the spectrum can be affected so that false conclusions can be drawn about the positions and the shape of the absorption bands. The knowledge of these influences of residual solvents in the polymer film is important for the correct interpretation of the reflection-absorption spectra. Unlike other approaches, a single reflection at a 20° incidence angle was used. A new drop-carting technique was used for the deposition of polymer film solutions on metal mirrors. Reflection-absorption spectra at a near-normal incidence angle were obtained using a dispersive infrared spectrometer.

A Computational Study of a Prebiotic Synthesis of Ergosterol, Ergocalciferol & Cholecalciferol (Vitamin D2 and D3)
Authors: Aylward Nigel
Published: April 2023

The magnesium ion metalloporphyrin complex is shown to bind the ligands ethyne (e) and propyne (p) on the metal or nitrogen pyrrole sites as a two-site catalyst in their copolymerization. The order of addition of the monomers is (epep) to form the side-chain. The steroid ring D (pep) is formed first from the propyne adduct bound to the metal site and the nonane adduct bound to the N-site. The optimal orientation of these adducts determines the β-orientation of the 17-substituent. Further addition of three ethyne monomers forms an N-diene cyclopentene derivative able to cyclise to form the steroid ring C (pee) with a trans conformation and a 13-β methyl substituent. Further addition of propyne forms the B-ring (eep), followed by two ethyne to form the A-ring (pee). Reaction with a hydroxyl anion and a proton allows the catalyst to separate. Final hydrogenation renders ergosterol, photolysis leading to ergocalciferol (Vitamin D2). The reactions have been shown to be feasible from the overall enthalpy changes in the ZKE approximation at the HF and MP2 /6-31G* level, and with acceptable activation energies.
Procesos de formación en sitios concheros de la costa meridional de Santa Cruz. Un abordaje desde el material lítico.
Authors: Cañete Mastrángelo Daniela S
Published: April 2023

El objetivo de este trabajo es ampliar el conocimiento sobre la variabilidad con que los agentes tafonómicos impactan sobre el registro arqueológico proveniente de la costa meridional de la provincia de Santa Cruz, específicamente, sobre aquel que forma parte de sitios conchero que se encuentran en la localidad arqueológica Punta Entrada y actual Parque Nacional Monte León. Para ello se analizan los materiales líticos recuperados en distinta situación de exposición (estratigrafía y materiales en superficie) y datados en el Holoceno medio y tardío. Concretamente se utilizan indicadores de exposición subaérea y enterramiento como son el impacto de la erosión eólica y la presencia de precipitados de carbonato de calcio. Se concluye que, según los datos relevados, no habría diferencias en la forma en la que se expresan ambos efectos tafonómicos según la matriz que contenga a los artefactos.
Sobre sitios históricos en contextos urbanos. El caso de la antigua reducción “Nuestra Señora de la Concepción de Ibitiracuá” (Concepción de la Sierra, Misiones, Argentina). Nuevos avances y perspectivas de estudio.
Authors: Ocampo Amanda Eva
Published: April 2023

En el contexto de los territorios sudamericanos en donde existieron misiones fundadas por jesuitas (1609- 1768) y en convivencia con grupos indígenas, muchas de ellas fueron parte de una continuidad ocupacional, a través de reconstrucciones y distintos procesos de reutilización a lo largo del tiempo. En la actualidad la provincia de Misiones tiene múltiples sitios arqueológicos que cuentan con estas características, ubicados en municipios y pueblos de la región. En este trabajo se presenta parte de los resultados del proyecto de investigación denominado “Rescates arqueológicos como elementos de activación patrimonial en sitios urbanos” realizado a partir de una beca posdoctoral de CONICET. Desde la investigación arqueológica, se presentan los trabajos de excavación y algunos hallazgos de mayor relevancia del sitio de la reducción de “Nuestra Señora de la Concepción de Ibitiracuá” o Concepción, fundada en el año 1619.  Además de contar la metodología de trabajo propuesta, también se hace hincapié en el desafío de excavar en suelos húmedos y selváticos, que también cuentan con distintos procesos de formación de sitios de manera antrópica, y con reutilización tanto material como espacial. De esta manera el objetivo principal es contribuir a las investigaciones arqueológicas que se centran en reducciones y sumar al corpus de información, propuestas metodológicas de exploración de sitios en contextos urbanos tales como nuestro caso de estudio.
Utopia Ideology in Creating Fabric and Fashion Design
Authors: Hakim Dhayea Dr. Mohammed
Published: April 2023

The current research has enabled both designer and recipient to move to a wide range of designs that became a rich source for the designer to use according to the ideology of the design idea. that group made a knowledge asset for the recipient, where this transition allowed to design products and non-compliance with a certain stereotype. Besides, the displacement of the concept of artistic sanctity, as well as that allowing transition from privacy to generality and the employment of imagination in a way that represents reality or is close to it. The first chapter dealt with the research problem and the need for it, as well as identifying the utopia ideology in the formation of fabric and fashion designs. Then, the research dealt with its limits, the designs of printed women’s fabrics and fashions for certain groups, and the researcher was able to define the terms according to the scientific research methodology. The second chapter contains topics, while the third chapter represented the research procedures and the analysis of models. The researcher concludes the results within the fourth chapter, the most important of which were: 1- Utopia ideology in all models relied on simulating the essence to move the recipient's perception from the apparent qualities of that vocabulary to the process of analyzing and assembling those works. Subsequently, reaching the idea of Utopia, was able to achieve the displacement of sanctity for some concepts of design ideology and give complete freedom to the designer and the choice of the recipient. 2- The formal structure of the design was able to achieve the interaction between the society and the age of use, forming a special thought that included the ideology of utopia, which relied on that interaction, leading to conclusions, recommendations, proposals, and sources
