Adaptaciones en la arquitectura del Centro Histórico de Granada, Nicaragua
Authors: Cruz-Ramírez Luis Carlos
Published: December 2021

En este artículo se explica la relación entre la dotación de equipamiento turístico y la adaptación de la forma de los edificios en los centros históricos. Se seleccionó como objeto de estudio el centro histórico de la ciudad de Granada, Nicaragua. De todos los géneros de edificios, se estudió la dotación en edificios habitacionales. Posteriormente, se tomó una muestra de edificios que experimentaron cambio de uso, de habitacional a equipamiento turístico. Se analizaron los espacios que cambiaron su uso, así como las posibles adaptaciones. Estos datos se ordenaron y se les asignaron valores para posteriormente realizar análisis probabilísticos. Se encontró que existe una mayor frecuencia (63.2%) de espacios que experimentaron adaptaciones formales cuando existe dotación turística. Existe una relación entre el cambio de uso de los espacios y las adaptaciones, con correlación de 77.21%. Estos resultados indican que, a mayor cantidad de cambios de usos en un edificio, se presenta mayor cantidad de modificaciones formales. Estas modificaciones se tienden a llevar a cabo para que los espacios funcionen. Se deben principalmente a que las actividades turísticas desarrolladas en los espacios arquitectónicos son diferentes a las actividades realizadas en la vivienda. Estos hallazgos pueden ser de utilidad para la orientación de los proyectos de intervención en edificios patrimoniales.

La investigación y metodología abordan archivos fotográficos que, como fuentes primarias, relatan una urbanización en relación con las culturas locales, prácticas obreras y artesanales, que configuran una población asentada hace cerca de un siglo con regulaciones sociales que impactaron sus prácticas culturales y movilidad urbana y que construye una forma comunitaria de interacción social.
Análisis de restauración de la iglesia Santa Lucia de San Sebastián, Retalhuleu y revitalización del entorno inmediato
Authors: Mazariegos Meneses Luis E.
Published: December 2021

La Iglesia de Santa Lucía de San Sebastián Retalhuleu, Guatemala se encuentra abandonada, recibiendo las inclemencias del tiempo,  con serios daños provocados por distintos factores, entre los cuales se encuentran la falta de mantenimiento a lo largo del tiempo, además de acontecimientos telúricos que han incrementado el deterioro, siendo el de 17 junio del año 2017 el último que dañó seriamente los vestigios de la fachada principal, haciendo colapsar el muro de esta, los revoques que aun existían, y exponiendo la mampostería original.  Otro problema latente, lo constituyen las distintas intervenciones que se han hecho, las cuales han sustituido materiales originales, por materiales contemporáneos, sin ningún criterio apropiado. El funcionamiento espacial para el cual fue diseñado el edificio ha dejado de satisfacer sus necesidades primigenias. Su historia general plantea que han sido distintos los usos que se le han dado a lo largo del tiempo, siendo a principios del siglo XIX, primero ermita, para proteger la imagen de Santa Lucía, mandada a construir por el Señor Cristóbal Cochajil; para ser luego una iglesia. Posteriormente a ello otros variados usos, desde bodega para materiales, sala de reuniones para los feligreses y distintas organizaciones católicas, y actualmente abandonado en su totalidad, lo cual ha provocado que se le hagan las modificaciones necesarias para que estos puedan funcionar, todo ello carente de criterios que protejan la originalidad del edificio, y poniendo en peligro el valor patrimonial del mismo.
FRT and Transient Stability Augmentation of Grid-Connected PV Station Using Virtual Synchronous Generator
Authors: Islam Md. Kamrul , Mannan Mohammad Abdul , Hazari Md. Rifat
Published: December 2021

Due to the extensive integration of renewable energy sources (RESs), i.e., photovoltaic (PV) system, the future power system is developing into an inverter-based system from a dominated alternator-based power system. This massive penetration of inverter-based PV system reduced the system inertia and damping characteristics of the power grid, impacting the fault ride-through (FRT) capability and causes frequency instability. Modern grid codes require that PV systems should work in the same way as conventional power plants and assist the system during transient state. However, most of the conventional inverter control mechanisms failed to fulfill the requirements of grid codes, especially when the penetration ratio of the PV system is close to the conventional unit. Therefore, this paper proposes a virtual synchronous generator (VSG) control mechanism of PV system inverter to augment FRT competency and frequency stability. The proposed VSG control system mimics the behavior of conventional power plants. To observe and evaluate the proposed controller behavior, simulation analyses were executed in the PSCAD/EMTDC software for both proposed and conventional controllers. The simulation results clearly indicate that the proposed VSG control system has sufficient damping characteristics to ensure FRT capability and frequency stability.
Review of Different Error Metrics: A Case of Solar Forecasting
Authors: Singla Pardeep , Duhan Manoj , Saroha Sumit
Published: December 2021

Renewable energy systems (RES) are no longer confined to being used as a stand-alone entity in the modern era. These RES, especially solar panels are also used with the grid power systems to supply electricity. However, precise forecasting of solar irradiance is necessary to ensure that the grid operates in a balanced and planned manner. Various solar forecasting models (SFM) are presented in the literature to produce an accurate solar forecast. Nevertheless, each model has gone through the step of evaluation of its accuracy using some error measures. Many error measures are discussed in the literature for deterministic as well as probabilistic solar forecasting. But, each study has its own selected error measure which sometimes landed on a wrong interpretation of results if not selected appropriately. As a result, this paper offers a critical assessment of several common error metrics with the goal of discussing alternative error metrics and establishing a viable set of error metrics for deterministic and probabilistic solar forecasting. Based on highly cited research from the last three years (2019-2021), error measures for both types of forecasting are presented with their basic functionalities, advantages & limitations which equipped the reader to pick the required compatible metrics

Authors: Rahman Mashiour , Rahman Rosshairy Abd. , Habib Md. Mamun
Published: December 2021

The mobile devices are used to execute the teaching-learning-evaluation process in Mobile Learning (m-learning) methodology. M-learning is a trending field in educational organizations, companies, and for individual study. With the explosion of mobile device ownership among the users aged within 18–29 years who are also the attendees of the higher learning institution (HLI), gives us the opportunity to consider the use of m-learning methodology to be embedded in the HLI beside traditional methodologies. Exceptional circumstances such as the COVID-19 pandemic when traditional face-to-face methodology suddenly changed to online paradigm, is also forcing us to strongly consider the m-learning approach. However, HLI may not have a general policy to implement m-learning into the traditional learning environment. A proper educational outcome needs to be configured to implement a new process into the traditional process. Therefore, a model integrating the m-learning aspects and the education supply chain management factors obtained from this study may benefit the stakeholders of HLI, especially educators and students.
46 NUMARALI PAPİRÜS IŞIĞINDA ANTİKÇAĞ’DA BÜYÜCÜLÜK
Authors: BATAN Meryem , TURHAN İhsan
Published: December 2021

Antik çağa ait büyü papirüsleri 19. yüzyılda ortaya çıkmaya başlamıştır. İlk çalışmalar daha materyalist bir yaklaşımla bu papirüsler yorumlanmadan yalnızca çevrilmekle yetinilmiştir. 20. yüzyılın ilk yarısından itibaren ise daha kapsamlı ve bu papirüslerin yorumlanmasına yönelik çalışmalar meydana getirilmiştir. Özellikle erken Hristiyanlık döneminde dini hayatın algılanışı ve bu tarz ezoterik yaklaşımlara etkilerini görmek açısından değerli olan bu papirüsler Mısır merkezli Hellenistik kültür ve Hristiyanlığın yorumlanışı hakkında önemli bilgiler sağlamaktadırlar. Bu çalışmayla hedeflenen bu papirüslerin Hem Türk literatürüne kazandırılması hem de Erken Hristiyanlık döneminde büyü mefhumunu değerlendirmektir. Mısır Tarih boyunca gerek dini gerek etnik olarak karmaşık bir bölgedir. Politeist inanç yapısı Hellenistik dönemle birlikte daha da artmış Hellen kökenli tanrı kültleriyle kaynaşmış bir inanç yapısı ortaya çıkmıştır. Papirüsün ait olduğu dönemde ise bu kaynaşmış inanç yapısına Yahudi ve Hristiyan öğelerin de eklenmiş olduğu bir yapı karşımıza çıkmaktadır.

The Study of Comprehensive Risk Management and Corporate Finance Constraints
Authors: LuoChen Qingqing , Chen Mengyuan , Liao Jie , Xu Zhongqi
Published: December 2021

The reasons why companies implement comprehensive risk management and the benefits it can bring to companies have been a subject of academic interest. However, there is still room for further exploration of this topic for the following three reasons: firstly, most of the existing literature is focused on the study of corporate performance and value, and there is less research on the level of corporate financing constraints; secondly, a few papers have initially explored the relationship between the implementation of comprehensive risk management and corporate financing costs, but the research on the intrinsic impact mechanism remains at the theoretical level and lacks empirical testing Finally, comprehensive risk management has been a hot topic in recent years, but most of the literature has focused on developed countries such as Europe and the US, and domestic research is still very limited. Therefore, this paper attempts to empirically test how the implementation of comprehensive risk management affects corporate financing constraints, in the hope that it can complement the existing literature.

Published: December 2021

The study was carried out to assess the contribution of farm tree on the household economy of the users of Kankali Community Forest in Chitwan, Nepal. Household survey, focus group discussion and key informant survey were used to get primary information. Stratified random sampling was used to select sample households on the basis of wealth class. A total of 200 households were taken for interview. People’s dependence on fuel wood was found high. Rich people had more trees on their farm land as compared to medium and poor people. Farm trees were mostly used for fodder purpose and less for timber, fuel wood and fruits. Contribution of non-farm sources (salary, business, remittance, wage, etc.) to household economy was high (86.6%) followed by farm source (agriculture/livestock) (9.5%), forest (2.5%) and farm trees (1.3%). Percentage contribution of non-farm, agriculture/livestock and farm tree sources was more for rich households as compared to medium and poor households. Forest resource was a greater source of income for medium households than other two categories. Rich class households prefer to collect more timber, fuel wood and fodder from forest, medium households prefer to collect more grass, sand, mud and wild vegetables while poor people collect more poles, wild fruits and bamboo/rattan as compared to other classes of households. The perception of the people was found positive towards having farm tree and its importance to household economy though the percentage share of farm tree income for household economy was least.

Published: December 2021

Pseudoperonospora cubensis (downy mildew) is highly virulent to various Cucurbitaceae crops, including cucumber (Cucumis sativus). We tested chlorine dioxide application in a plastic greenhouse for environmentfriendly control of downy mildew disease. Spraying diluted chlorine dioxide suppressed downy mildew disease with 41.2% control efficacy. Thermal fogging with chlorine dioxide had a high control efficacy of 80.9%, confirming that this approach is useful for environment-friendly downy mildew control. Using thermal fogging to control diseases that are greatly affected by humidity, such as downy mildew, may be more effective compared with conventional dilution spray control methods.

Published: December 2021

In the present study, kinematic divergence computed using ECMWF grid point data at 850 hPa  is enhanced by  using the relationship between OLR and divergence. This new enhanced divergence is used to  compute the velocity potential and then, the divergence part of the wind is obtained from velocity potetial. To obtain the rotational part of wind, we computed the vorticity from wind data, and subsequently stream function and obtained and the rotational part of the wind from the stream function. The total wind is the combination of divergent part obtained from modified velocity potential (using OLR data) and rotational part from unmodified stream function. This total wind field is used as initial guess for univariate objective analysis by optimum interpolation scheme so that Initial Guess field contained the more realistic divergent part of the wind. Consequently, the analysed field also will contain the divergent part of the wind.

Authors: TIWARI V. S.
Published: December 2021

. Variations in ozone amounts have been studied using data obtained with Dobson spectrophotometers during 1966-1988 at Srinagar, New Delhi, Pune and Kodaikanal. Yearly average values of total ozone , and its vertical distribution by the Umkehr method in layers 1 to 9 have been computed. Departures from compo- site avarage value for the period (1966-1988) have been computed for both total ozone and its vertical distribution. The variation over New Delhi and Pune have been compared with those at Arosa reported by Dutsch {1989).  The observed variations in the ozone distribution at New Delhi and Pune can be explained, as being within normal interannual changes. Tropospheric ozone in layer lover New Delhi shows some effects of an anthropogenic nature, on the other hand Pune does not exhibit in any influence of pollutants in any layer, either in the troposphere or stratosphert.

Agroclimatic classification for assessment Of the crop potential of Karnataka
Authors: KHAMBETE N.N.
Published: December 2021

To plan cropping pattern and to bring out agricultural potential of a region, it is essential that the agro climatic classification is made on an objective and rational basis. Such an attempt has been made in this paper by devising an index called Water Availability Index (WAI). This index takes into account the distribution of the minimum water required by the crop. It utilizes the most probable number of the wet weeks for three threshold values of weekly rainfall and probability of dry spells of more than three weeks. The methodology developed is applied to dry farming tracts of Karnataka State. Using these information along with the information of the soil types and water requirement of different crops, cropping pattern can be assessed in each agro climatic zone, so that optimum use of the available moisture is made in stabilizing the crop production in the State.

See breeze like cloud-free zones during Monsoon months
Authors: MANDAL J. C. , HALDER S. R.
Published: December 2021

Characteristic features of district cloud-free zones and their day to day evolution along Indian coasts as observed in INSAT cloud imageries during southwest monsoon months  have been analysed and discussed along with sea surface and surface air temperatures and monsoon condition situation. It was a weak or break monsoon condition. Appearance of early morning clear zone just off shore along Indian Peninsula coasts is attributed to the gradual lowering of sea surface temperate due to upwelling caused by persistent favorable surface wind and slow-setting of air above colder water. With the advance of the day, wide extension of clear area over water where it ends abruptly and propagation of front-like zone inland manifest as a typical sea breeze. It is postulated that this is the effect of sea breeze circulation and shrinking of air above colder water. It is inferred that time-to-time appearance of such phenomenon may be an Indication of longer weak or break monsoon over the Peninsula.

Published: December 2021

The concept of Maintainability (M) of electronic instruments. though of recent origin, has Important application for meteorological equipments, which have special requirements. M is defined quantitatively in terms of mean time to repair and is Influenced by the failure behaviour of an equipment. An equipment goes through teething trouble, useful and terminal phase. Much of  maintainability can be incorporated during design and production phase. This reduces the effective overall cost of the equipment during its life time. Special maintenance support system is necessary for meteorological Instruments. Some recent tools for trouble shooting in digital systems have been discussed.

Published: December 2021

A non-divergent barotropic model has been formulated on the basis of splitting up method and used to study the circulation in the north Indian Ocean (1-26° N, 4~-99° E). The circulation was simulated for summer and winter seasons separately. It IS found that the model simulated the summer and winter calculation satisfactorily. It is also found that the meridional component of wind stress IS dominant over the zonal component in shaping the Somali current. Some sensitivity studies were also carried out and the results indicate the importance of wind stress curl.

Evolution of two troughs in the tropical Indian Ocean and their characteristic features
Authors: SINGH M.S. , Lakshmanaswamy B.
Published: December 2021

Evolution and characteristic features of double trough systems in the tropical Indian Ocean have been studied with the help of Climatological Atlas (Part I andIl) ~f the Tropical Indian Oc.ean (Hastenrath and Lamb 1979). It is confirmed that there are two troughs (Northern Hemisphere EquatorIal Trough and Southern Hemisphere Equatorial Trough) in this region (including south Asian landmass) all the year round, one in northern hemisphere and the other in southern. Both are migratory in nature and, perhaps, thermal in origin.  In the convergent zones of the two troughs, there is extensive cloudiness. The migration of these trough systems during their respective summer seasons appear to be related to the extensive heating of the south Asian/ African land masses surrounding the Indian Ocean in north and west.
IMPLICIT NONLINEAR NORMAL MODE INITIALIZATION FOR A BAROTROPIC PRIMITIVE EQUATION LIMITED AREA MODEL
Authors: NAIR D. R. C. , CHAKRAVARTY B. , NIYOGI P.
Published: December 2021

A simple version of implicit nonlinear normal mode initialization is applied to a limited area one-level primitive equation model over a tropical domain. The model formulation is based on shallow water equations in spherical co-ordinate and potential enstrophy conserving finite difference scheme is employed. The model is used for predicting the movement of a typical monsoon depression formed over the Bay of Bengal. The above scheme is found to be very effective as it requires only three iterations for attaining balance between the mass and wind tields. However this model is not able to predict the movement of the depression very ac-curately due to the limitations of such a one-level model.

Authors: SINGH VARTIKA , DEV PRAMENDRA
Published: December 2021

The environmental implications of rainfall pattern in replenishment of ground water system of Saharanpur region, located in western Uttar Pradesh, have been discussed. The mathematical analysis of rainfall dissimilarity of Saharanpur region for a period of 50 year (1959 to 2008) display a quite good range from 497.70 to 4357.5 mm with an annual average rainfall value of 1209.8 mm. The positive trend of departure from the computer value of average annual rainfall exhibits appropriate periods for recharge of ground water reservoir. The recorded data of annual rainfall during the last 3 year reveal values below the calculated annual average rainfall, pointing out negative trend. The statistical analysis of rainfall data involves computations of various statistical parameters, which also support the negative trend of rainfall. The prediction of expected future rainfall trend for a period up to 2018 has been made, which indicates a negative trend. The proposal have been incorporated to implement a plan for augmentation of ground water resource and also to develop possibilities of rainwater harvesting.
Satellite derived sea surface temperature variability in the Bay of Bengal
Authors: SINGH O.P.
Published: December 2021

Bay of Bengal is associated with disturbances like tropical cyclones and monsoon depressions during pre and post monsoon and southwest monsoon seasons respectively. The Sea Surface Temperature (SST) variability over the Bay of Bengal plays an important role in the genesis of these disturbances. Satellite based SST climatologies, though based on shorter duration of data, have enabled study of interannual variabilities of SST over the smaller regions of Bay of Bengal which are associated with different types of weather disturbances in different seasons. Interannual variabilities and recent trends in SSTs over different regions of Bay of Bengal have been presented using a reliable satellite based climatological data for the 14 year period from 1985-1998.The annual SST over the Bay of Bengal has risen at the rate of about 0.2°C /decade during the period from 1985-1998. Maximum rising trend of 0.71°C/decade has been found over south Bay of Bengal during June. Frequency of monsoon depressions has decreased considerably in recent years in spite of increasing SST trends over Bay of Bengal in southwest monsoon season.

Authors: JYOTI L.M. , SEN SANJIB
Published: December 2021

Transit of Venus over the solar disc is an extremely rare event. The phenomenon occurred last time on June 8, 2004 when the entire event was visible from all parts of India. Another Transit of Venus is going to occur on June 6, 2012, though the entire event will not be visible from India. The Positional Astronomy Centre publishes data on Transit of Mercury and Venus in its annual publication ‘The Indian Astronomical Ephemeris’. In this paper an attempt has been made to provide documentation on the methodology for computation of contact timings of the event. Using the methodology, the geocentric contact timings and local contact timings for important places of India for the event of Transit of Venus of June 6, 2012 have been predicted. The result thus obtained for different geocentric phases of the event has been compared with the predicted timings published by The Nautical Almanac Office, United States Naval Observatory and NASA.

Intraluminal duodenal “windsock” diverticulum; Case Report and discussion
Authors: Asselhab Salem
Published: December 2021

Intraluminal duodenal diverticulum (IDD) is a rare developmental anomaly usually found in the second portion of the duodenum. The cause appears to be a failure of recanalization of the occluded foregut lumen of the human embryo, resulting in a fenestrated mucosal membrane [1]. A small aperture in this diaphragm will gradually cause it to elongate caudally in response to duodenal peristalsis to form the so called “wind-sock” configuration. Symptoms are nonspecific and generally depend on the degree of duodenal obstruction; 25% of cases are associated with GI bleeding. In most documented cases, IDD was diagnosed radiologically, but the value of endoscopy for diagnosis and treatment has been amply demonstrated.
