Published: April 2023

Arwana fish is an ornamental fish that has high aesthetic value and is popular with Indonesian people. Silver Arowana is a type of freshwater ornamental fish originating from Brazil and belonging to the Osteoglossum genus. Problems in arowana fish farming include water quality, disease, nutrition and spawning (breeding). An important problem in enlarging silver arowana fish seeds is one of the maintenance media. Water quality is an external factor that plays a role in supporting fish growth. Water quality management has been one of the inhibiting factors in aquaculture, because it requires time, procedures and several stages to assess aquaculture water quality parameters, so farmers are late in handling the fish which results in death. Monitoring water quality that is practical, efficient and easy according to the development of IOT-based information technology 4.0 is urgently needed by cultivators to control fish in real time so that fish survival can be optimized. The research will be carried out for two years, namely 2022 and 2023. The purpose of the first phase of the research is to create an IOT-based Water Quality Monitoring System (SIMONAIR), while the second stage of research aims to apply the use of SIMONAIR to support the growth of arowana fish. The research was conducted at the Vocational School of IPB and in collaboration with a partner, namely CV Viez Aquatics. Phase 1 research will focus on the manufacture and calibration of SIMONAIR. Phase 2 research The use of the SIMONAIR application on silver arowana fish given different feed treatments. The overall research results are a technology package for silver arowana fish cultivation with high technology for the community or fish farmers

Insights from the molecular docking analysis of EGFR antagonists
Authors: Alam Qamre
Published: April 2023

Overexpression of the epidermal growth factor receptor (EGFR) has been shown to be a critical factor in tumor development and cancer progression. Although established EGFR inhibitors have been effective in the treatment of cancer, they are associated with several side effects. As a result, there is an urgent need to develop novel EGFR inhibitors that can effectively target the receptor while causing no adverse side effects. Here, the bioactive compounds of Glycyrrhiza glabra and established EGFR inhibitors have been screened against the EGFR catalytic site. The compounds LTS0058805, LTS0114552, LTS0128805, LTS0174203, LTS0007447, and LTS0164690 exhibited binding energies to the EGFR that were comparable to those of established EGFR inhibitors. Further, these hit compounds were observed to interact with critical residues of the EGFR, suggesting their potential as inhibitors of the receptor. In addition, these hits possess good drug-like properties and merit further exploration for their potential application in cancer management.

Authors: Mehta Vini
Published: April 2023

It is of interest to study the efficacy of botulinum toxin injection in masseter reducing bigonial width of the face. Online databases such as PubMed, Cochrane Library, Google Scholar, Science Direct database and ResearchGate were searched from initiation until October 2022 using keywords such as “masseter muscle injections”, “botulinum toxin,” “bigonial width reduction,” “masseter muscle hypertrophy,” and “lower face contouring” All available retrospective as well as prospective studies, were included with specific weightage to the efficiency of Botulinum Toxin (BT) injection in masseter muscle and the technique, unfavorable events, and the extent of its effects. A total of 20 publications were acknowledged. All prospective studies were included. Relevant data on patient selection, injection methods, efficiency, dose, rate of recurrence, and significant side effects of BT injections in masseters were collected. All excluding one were prospective studies. Bilateral injections were used in all the studies. Follow up period was 3-48 months. This systematic review focuses on the effectiveness of Botulinum toxin injection in lowering the bigonial width by decreasing the volume of the masseter. Repeat treatment at regular intervals is advisable to maintain desired results. The procedure was carried out in an office environment and was completed within 15 mins. There are no permanent adverse events related to the procedure. Further studies involving randomized control trials with larger sample sizes are warranted to optimize the dose and frequency of BT injection.

It is of interest to investigate that the phytochemical analysis, in-vitro antioxidant potential and glycosidase inhibitory potential of Asanadi gana a polyherbal formulation. Asanadi gana is a classical Ayurvedic polyherbal formulation, markedly used for alleviation of Prameha and medodosha, which correlates in many ways with obesity, metabolic syndrome, and diabetes mellitus (madhumeha). The phytochemical constituents, total phenolic, total flavonoids, total tannin content, total antioxidant capacity, total reducing power, and free radical scavenging activity of the polyherbal formulation extracts were determined. Comparing it to the common medication Acarbose, its inhibitory impact against the digestive enzymes α-amylase and α-glucosidase was also examined. The formulation showed the presence of major constituents such as terpenoids, triterpenoids, sterols, flavonoids, tannins, phenolic, saponins, alkaloids and Glycosides. The ethanol extract had high phenolic content and flavonoid content, whereas the aqueous extract had more tannin content (181 ± 5.5µg/mg), (132 ± 5.50 µg/mg), (22± 1.6 µg/mg respectively. we conclude that the extracts of ayurvedic polyherbal formulations, particularly ethanol extract are a potential source of natural antioxidants and remarkable glycosidase inhibitory activity. Hence, Asanadi gana has the potential to be a safe and effective natural treatment for the delay or prevention of diabetic complications.
Methodology of Investigation of Crimes Committed Against Minors
Authors: Filimonov Arkadii Dmitrievich , Zav'yalov Aleksandr Nikolaevich
Published: April 2023

The subject of this study is the specifics of the investigation of crimes in which the victim was a minor. Taking into account the provisions of Russian legislation, political and legal documents, according to which children are the most important priority of state policy, in their study the authors tried to reveal the importance of a qualitative approach in the investigation of crimes in which the victims are representatives of one of the most vulnerable categories of the population in our state. Special attention is paid to the age and, as a consequence, the psychophysical and personal characteristics of minors as determinants of the latter's insecurity. At the same time, the features of modern post-industrial society characterized by the spread of the Internet space to the daily activities of minors have guided researchers in developing recommendations for preliminary investigation bodies related to the search, receipt and use of information distributed through the Internet network during the investigation. The main conclusions of the study are that the methodology of investigating crimes committed against minors is significantly different from other private methods of investigation by the elements of crimes, since its creation is based on the characteristics of the object of criminal encroachment. At the same time, age is a defining feature. In turn, the specifics of the methodological recommendations should proceed from the level of development of the information society, which makes it possible to use the features of digital relationships in the investigation of crimes, the victims of which are minors. The contribution of the authors to the study of the topic is not only the preparation of practice-oriented recommendations for investigators and inquirers (for example, on issues subject to mandatory clarification during the investigation, the need to study the identity of the injured minor through the analysis of publicly available information), but also the nomination of some proposals to improve the activities of prevention agencies and the measures they take (in particular, to identify minors who have a tendency to suicidal behavior through the joint development of monitoring programs for the activity of minors in the Internet space).
Identificación de vías del metabolismo del hierro ligadas a la respuesta inmune en Salmón del Atlántico (Salmo salar) frente a brote natural de Piscirickettsia salmonis (P. salmonis)
Authors:   ,   Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, Sáez Beltrán Alejandro José
Published: April 2023

Gran parte de las pérdidas de la industria de salmonicultura son asociadas a la Piscirickettsia salmonis, agente causante de la Septicemia Rickettsial Salmonídea. Para lidiar con este patógeno la industria emplea vacunas y antibióticos, los cuales han demostrado ser insuficientes. Estudios previos han identificado a través de análisis genómico, un grupo de genes candidatos, en familias con resistencia natural al SRS, que podrían estar involucrados en generar esta inmunomodulación. Sin embargo, la mayoría de estos estudios se realizan bajo condiciones controladas. Por lo tanto, este trabajo apuntó a evaluar la respuesta de las vacunas en función de ciertos genes candidatos, bajo condiciones productivas, es decir, balsas jaula en mar. La metodología implicó medir el desempeño de 3 tratamientos con vacunas inyectables, uno de estos sin tener antígeno para SRS como vacuna control, otro con una formulación experimental y el último con la estrategia más empleada en la industria. Se muestrearon 5 animales por grupo desde marzo hasta agosto, extrayendo el riñón cefálico y evaluando el ARN mensajero mediante qPCR con partidores para genes involucrados con metabolismo del hierro y la respuesta inflamatoria. Los resultados indicaron que la expresión de Transferrina y TNF-α aumentan su expresión en el mismo tratamiento que posee menores niveles de mortalidades. Por ende, se demostró que las vacunas tienen un efecto de protección ante el SRS, además se observó una relación entre la expresión de genes relacionados con el metabolismo del hierro y la respuesta inflamatoria.
Reconversión urbana del Cono de Aproximación del ex aeródromo de Cerrillos a partir de su rol como eje de ventilación para Santiago
Authors:   ,   Pontificia Universidad Católica de Chile. Facultad de Arquitectura, Diseño y Estudios Urbanos, Bustos Neumann Antonieta Isabel
Published: April 2023

El Cono de Aproximación del ex Aeródromo de Cerrillos está situado en el sector sur-poniente de Santiago, abarcando parte de las comunas de Cerrillos, Maipú y San Bernardo. Esta ubicación geográfica tiene la particularidad de acoplarse con la dirección de los vientos predominantes que ingresan a la ciudad. Este rasgo, que en su momento fue valioso para el aeródromo, es también un factor esencial para la ventilación de Santiago, ya que estos vientos influyen positivamente en la calidad del aire y en la temperatura de la capital. La actual intención de las autoridades es que este espacio se urbanice, pero, los pasos que se han dado hasta ahora indican que existe el riesgo de que se limite el rol medioambiental del Cono. Sin embargo, todavía existe la posibilidad de evitar esta situación, ya que los proyectos todavía no se han ejecutado en su totalidad y la pieza sigue cumpliendo su función medio ambiental.
Elemento y conjunto ; modestia y discreción : comprensión del sistema patrimonial de Barrio San Eugenio para su desarrollo urbano en base a su patrimonio modesto
Authors:   ,   Pontificia Universidad Católica de Chile. Escuela de Arquitectura, Flores Escalona David
Published: April 2023

En cierta medida, todo barrio patrimonial popular se constituye por una cantidad de edificios con distintos grados de notoriedad. La mayoría se trata de viviendas, elementos básicos que da forma a la ciudad, las cuales destacan desde la noción de conjunto mas que desde su individualidad, fenómeno que también se refleja en equipamientos y comercios menores, formando una trama anónima. A pesar de esto, dicha trama siempre cuenta con edificios de pequeña escala que destacan por sobre el resto por modesto que ellos sean e independiente de su programa, los cuales son reconocibles tanto desde el conjunto como desde su individualidad, y, en consecuencia, conforman un Sistema Patrimonial Modesto. Barrio San Eugenio presenta esta condición, por lo tanto, este trabajo busca ahondar en el rol de estos sistemas dentro de su contexto, entendiendo desde su condición actual de elementos valorables como ser relevantes para el proyecto patrimonial de arquitectura. Así, se releva un potencial generalmente asociado a grandes hitos urbanos, para establecer estos Sistemas Modestos como oportunidad de desarrollo desde una perspectiva patrimonial que toma como centro al habitante actual. Esto se consolida en un proyecto de escala barrial que busca sentar las bases para un futuro proceso de densificación en donde no se afecten las dinámicas y condiciones patrimoniales de este, sino que las proyecte hacia el futuro.

Published: April 2023

Calama ha perdido su título del Oasis más grande del mundo, actualmente solo queda un 16% de su superficie en comparación a principios del siglo XX. En los últimos años se ha levantado con urgencia la conversación y acción sobre cambio climático a nivel mundial, Chile no siendo la excepción. Calama se encuentra en una situación particular, ya que es una de las ciudades que ha presentado un mayor aumento de temperatura en la última década, correspondiendo a 0,93°C, y pérdida de biodiversidad a pesar de encontrarse en la macro zona del norte en donde los temporales de precipitaciones son cada vez más frecuentes, produciendo múltiples inundaciones estacionales, exacerbando el clima extremo presente en la depresión intermedia del Desierto de Atacama. Estos factores y la alta contaminación atmosférica presente en la ciudad, han llevado a declarar Calama Zona Saturada. Además de la crisis ambiental, se encuentra posicionada como la ciudad con peor calidad de vida en todo el país. La presente tesis proyectual plantea la necesidad de adaptarse al impacto climático y la de recuperar la biodiversidad perdida en el Oasis de Calama como medida para mejorar la calidad de vida de los habitantes. Para esto se plantea un nuevo habitar proyectado a 2050, en el cual a través del reciclaje de recursos, especialmente de agua, y una arquitectura adaptada a las condiciones climáticas específicas de la ciudad como el viento y el sol, se instaure una propuesta regenerativa para la ciudad que ponga en valor el patrimonio natural que ya se posee. Se proponen viviendas insertas en lo que fue en su momento parte del Oasis, las cuales sean capaces de actuar como catalizadoras en la recuperación y posterior preservación de la biodiversidad de este, convirtiendo la relación entre el habitar y la vegetación en un sistema dinámico, respondiendo simultáneamente a la necesidad de vivienda. Con esta intervención se busca mejorar la calidad de vida de los ciudadanos y ser un ejemplo sobre cómo abordar los problemas climáticos cada vez más intensos y frecuentes en todo el país a partir de la arquitectura sustentable recuperativa a escala de vivienda colectiva, generando en conjunto una pieza urbana y así, hacernos cargo de las actividades destructivas realizadas por generaciones anteriores en el mundo de la construcción, aportando en la batalla contra la crisis climática actual.
Does the way democracy is obtained matter for economic development? : estimating the effect of transition to democracy with a coup
Authors:   ,   Pontificia Universidad Católica de Chile. Instituto de Economía, Mejía Barahona Emanuel José
Published: April 2023

This paper studies the effects of transition to democracy with a coup conditional on the occurrence of a transition to democracy. Additionally, the study by Meyersson (2016) is extended by analyzing the effects of successful coups conditional on an attempted coup. Finally, a case study is carried out for the coup at Honduras in 2009. The results show that those countries that transition to democracy with a coup achieve a GDP per capita growth rate 1/3 lower in the next 10 years than those who do it without this type of event. Regarding the effects of successful coups, these are differentiated, when they overthrow an autocratic regime the effect is positive, while when they overthrow a democratic regime their effect is negative. The results for the case study are consistent with the last one, the impact of the coup at Honduras in 2009 on GDP per capita growth rate was negative although minor, which can be explained by the nature of said event. The results suggest that democracy and the way in which it is obtained matters; however, its effect on long-term development continues to be positive.

Self-assembly of submonolayer-coverage organic films
Authors:   ,   Pontificia Universidad Católica de Chile. Instituto de Física, Corrales Iturriaga Tomás Patricio
Published: April 2023

In this work we present a study of self assembled submonolayer coverage organic films. The types of molecules studied here are n-alkane chains, mainly n-dotriacontane (n-C32H66), that are deposited on silicon substrates with a thin native silicon oxide layer (∼15Å). In this research we have developed a velocity controlled dip-coating device to prepare submonolayer films. We have identified the parameters that affect the coverage, morphology and structures that arise in the preparation of the film. The techniques used to characterize these films are Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). Fur- thermore, this is the first work that demonstrates that SEM is a plausible technique to study thin films of n-alkanes. The future importance of this research is related to the possibility of micro-structuring energetically homogenous surfaces with nanometer thick films using relatively simple techniques, such as velocity controlled dip-coating. Micro-structured patterns, such as the stripes reported here, could be applied as optical diffraction grids or as templates for other materials.In this work we present a study of self assembled submonolayer coverage organic films.

Comparison of Resistance to Fracture of Endodontically Treated Teeth Reinforced with Various Posts: An In-vitro Study
Authors: Ramachandran Sajani , Babu Suresh , . Manikandan , . Ranukumari
Published: April 2023

Introduction: Endodontically treated tooth reinforced with posts should restore its lost structural integrity, as well as withstand the various masticatory forces. Choosing the appropriate post, so that a durable prosthesis can be given, is often a challenge to a restorative dentist. Aim: To compare the resistance to fracture, of endodontically treated teeth restored with the various posts when subjected to compressive loads, and analyse the different types of fractures and cracks which are visible under normal eye, microscope and radiograph. Materials and Methods: An in-vitro study was conducted in the Department of Dentistry, Pondicherry Institute of Medical Sciences, Puducherry, India, from February 2019 to March 2020. Study was done with four types of posts namely cast post, stainless steel, fibre and titanium on seventy extracted teeth, which were randomly allocated into five groups with one group as control without any post. The teeth were subjected to increasing compressive loads with universal testing machine and the loads at which fracture occurred was recorded. The data was analysed statistically with one way Analysis of Variance (ANOVA) and the groups were compared with Tukey’s HSD test. The types of fractures that occurred were also analysed. Results: The loads at which the teeth reinforced with various posts fractured, showed significant difference (p-value <0.0001). The mean load at which fracture occurred for teeth restored without any posts was 711.6086 N and teeth with stainless steel post was highest at 1605.955 N. Those with titanium posts were found to have minimum microcracks (14.2%) when seen under dissection microscope. Maximum number of teeth with titanium posts had favourable fracture and withstood the load (64.29%), with fracture occurring only at root tip and no fracture elsewhere. Tukey’s HSD test was done to compare the fracture resistance between the groups at 0.05 level of significance. There was no significant difference in the load at which fracture occurred between groups. Conclusion: In the present study, of all different post and core materials, stainless steel post resisted highest load and titanium posts had favourable fractures.

Published: April 2023

Cutaneous Larva Migrans (CLM) is caused by penetration of skin by the third stage larvae of hookworms, and most commonly caused by Ancylostoma braziliense (dog hookworm). Humans act as dead-end hosts for this parasite. This series reports six cases of creeping eruptions that occurred on buttocks and back in four infants and on the feet in two toddlers. All the cases clustered after the rainy seasons in the months of December and January. Diagnosis was established based on history and clinical examination. All six children were administered five days of albendazole and they recovered completely. This series is presented to make readers aware of the underestimated public health problem in infants with distinctive skin eruptions of larva migrans occurring in the tropical subcontinent of Indian coastal areas. This is clinically relevant as treatment of this condition is very simple and cost-effective.

Authors: Kumar Rohit , Yadav Siddharth Raj , Kumar Amit , Mengar Manas , Gupta Nitesh , . Pranavish , Gupta Shweta , Sharma Divyendu
Published: April 2023

Introduction: Obstructive Sleep Apnoea (OSA) is traditionally evaluated using a diagnostic Polysomnography (PSG) which is then followed by a PSG with Continuous Positive Airway Pressure (CPAP) titration. Split Night PSG (SN-PSG) includes the diagnostic and titration study in a single night. Split Night PSG is a better technique however, the requirements for CPAP titration are too strict. Aim: To assess the accuracy of different duration of split night compared to a Full Night PSG (FN-PSG) in OSA Syndrome. Materials and Methods: A retrospective observational study was performed in the Department of Pulmonary Medicine at VMMC and Safdarjung Hospital, from January 2019 to May 2019 at Safdarjung Hospital was done. Apnoea-Hypopnea Index (AHI) was assessed at the 1 hour, 2 hour, 3 hour and 4 hour from analysis of SN-PSG data obtained from FN-PSG. Using the Area Under Receiver Operating Characteristic (AUROC) curve, it was compared to the FN-PSG. Calculations were made to validate the diagnosis by a 2 hour PSG using different AHI cut-off points (5/hour to 15/hour). Results: Data from 20 PSG recordings was processed. A stronger correlation of FN-AHI was demonstrated with AHI at 2 hour (p-value <0.0001) (r value=0.902). At 2 hours of study, with an AHI cut-off of 5 hour, the sensitivity and specificity was 92.9% and 83.3%, respectively. The Positive Predictive Value (PPV) was 100% and Negative Predictive Value (NPV) was 83.3% (AUROC=0.976; p-value <0.0001). At 2 hours, AHI cutoff of 15 hour, the sensitivity and specificity was 71.4% and 100%, respectively. The PPV was 100% and NPV was 86.7% (AUROC=1.000; p-value <0.0001). Conclusion: Split-night PSG is effective for diagnosing severe OSA. A lower cut-off of AHI may be used to qualify patients for CPAP titration.

Verma [3,4] information measures has attracted attention for a new class of inequalities during the tenure of investigation. The purpose of this communication is that to extrapolate novel inequalities associated with Verma information measures and different statistical distributions.
Mustard Allergy in Children and Cross-reaction: Case Report
Authors: Aminou Sara , Jellali Kaoutar , Mahraoui Chafiq
Published: April 2023

Aims: Food allergy to mustard is often unrecognised in children; however, it deserves early recognition as a potentially severe immunoglobulin e (IgE)--mediated allergy with a risk of anaphylaxis. The aim of this work is to show the value of performing an oral challenge test to confirm the diagnosis of mustard allergy.

Presentation of Case: We report the observation of a child who presented with allergy to yellow mustard with all the allergological work-up performed.

Discussion: The diagnosis of mustard allergy is delicate; on the basis of the clinical history and the food investigation, as mustard is consumed mainly in a masked form. Cross-allergies are common with mugwort, nuts and rosacea. No threshold value for skin tests or specific IgE can be considered sufficient to confirm or not the diagnosis of food allergy or the secondary acquisition of tolerance to mustard.

Conclusion: Oral challenge test is the gold standard for confirming the diagnosis of food allergy; reducing the risk of accidental exposure; validating or not the avoidance diet; and improving quality of life.

Coconut juice is a natural drink from coconut fruit. This study was aimed at evaluating its positive potential on biochemical indices. Fresh coconut fruits were de-dshelled and washed. The cotyledon was broken to extract the water which was used in blending the fruits. The extract was filtered and the filtrate was collected in a vial. Twenty healthy male Wistar rats weighing 160 -180 g, were grouped into two groups of ten rats each and were treated as follows for four weeks. Group A: control rats received oral dose of 2 mL/kg body weight of distilled water once daily for 28 days, and group B: received oral dose of 2 mL/kg body weight of coconut juice extract once daily for 28 days, both groups were, however, allowed free access to feed and water ad-libitum. The animals were weighed before and on completion of the experimental protocol. Blood was also collected via cardiac puncture and used for renal function and lipid profile assay, kidneys were excised and weighed, homogenized and the supernatant was used for antioxidant enzyme evaluation. Findings showed that there was no significant change (p>0.05) in the kidney-to-body weight ratio and renal function indices. Significant reduction (p<0.05) was seen in cholesterol, triglycerides, LDL but with an increase (p<0.05) in HDL. Antioxidant enzymes were significantly increased (p<0.05). The study concludes that coconut juice extract has positive stimulatory potentials on antioxidants, renal functions and lipid parameters of wistar rats.

At the Department of Agronomy's Crop Research Farm, SHUATS, Prayagraj, a field experiment was carried out in the month of Zaid 2022. (U.P). The soil in the experimental plot had a sandy loam texture, a pH of 7.1 that was almost neutral, a low level of organic carbon (0.36%), and low availability of the nutrients N, P, K  (171.48 kg/ha, 15.2 kg/ha, and 232.5 kg/ha, respectively). Ten treatments, each replicated three times, were used in the experiment, which was set up using a randomised block design over the course of a year. The treatments which are T1: Sugar-75 + 0.1 % boron foliar application, T2: Sugar-75 + 0.2 % boron foliar application, T3: Sugar-75 + 0.3 % boron foliar application, T4: Madhuri + 0.1 % boron foliar application, T5: Madhuri + 0.2 % boron foliar application, T6: Madhuri + 0.3 % boron foliar application, T7: Misthi + 0.1 % boron foliar application, T8: Misthi + 0.2 % boron foliar application, T9: Misthi + 0.3 % boron foliar application, T10: Control - N:P:K-120:60:40(kg/ha) are used. The results showed that treatment T9-Misthi + 0.3% boron foliar application was recorded significantly higher growth parameters like Plant height (175.5 cm), Plant dry weight (141.6 g/plant) at 80 DAS and highest Crop growth rate (22.1 g/m2/day) at 60-80 DAS. However, yield attributes and yield parameters like No. of Cobs/plant (1.81), No. of Grains/Cob (617.7), No. of Rows/cob (14.37), Seed index (68.4 g), cob length (18.5 cm), Grain yield (9.5 t/ha), Stover yield (15.4 t/ha) were recorded with the treatment T9-Misthi+ 0.3 % boron foliar application.
Climate Change Data: Use of an Autoregressive (AR) Model in Presence of Change Points under a Bayesian Approach
Authors: Achcar Jorge Alberto , Barili Emerson
Published: April 2023

In this study, we introduce a statistical model applied to climate change data consisting of an autoregressive times series (AR) model which represents a type of random process. A Bayesian approach using MCMC (Markov Chain Monte Carlo) methods is considered to get the inferences of interest. The main goal of the study is to have a model to get good predictions for mean temperature and also good to identify the time of possible change-points that might be present in the time series which could indicate the possible beginning of a change in climate. Applications of the proposed model are considered using annual average temperatures in some locations obtained over a period of time ranging from the end of 1800’s to a popular Bayesian discrimination criterion using MCMC methods.In addition to a good fit of the proposed model for the data, the model also was used to detect the times of climate changes in the different climate stations using CUSUM methodology.

Rice bean (Vigna umbellata) is one of the under-utilized crops which can become a promising pulse crop. A field experiment was conducted during kharif season of 2020 at Research Farm, College of Agriculture, Central Agricultural University, Imphal, Manipur to study the effect of planting geometry and nutrient management on yield, economics and quality of dwarf rice bean under rainfed condition. The experiment was laid out in Factorial Randomized Block Design (FRBD) and nutrient management which was replicated thrice. The treatments comprised of three planting geometry viz; S1 : 30 cm x 10 cm,  S2: 45 cm x 10 cm and S3: 60 cm x 10 cm and four nutrient management practices viz; F0: Seed treatment with molybdenum + phosphate solubilizing bacteria (PSB), F1: 20 kg P2O5/ha + seed treatment with molybdenum+ PSB, F2:40 kg P2O5 /ha + seed treatment with molybdenum+ PSB and F3: 60 kg P2O5 /ha + seed treatment with molybdenum+ PSB. Results indicate that planting geometry at 60 cm × 10 cm and nutrient management at 60 kg P2O5/ha with seed treatment of molybdenum + phosphate solubilizing bacteria (PSB) significantly influenced the yield and quality of dwarf rice bean and gave the maximum economic returns. The highest seed yield (14.65 q/ha) was recorded with spacing S3 which was significantly superior over S1 upto the tune of 8.7% (13.37q/ha). Among the different nutrient management practices, highest seed yield (16.01 q/ha) was recorded from F3 which was found to be at par with F2 (15.70 q/ha) and significantly superior over F1 and F0 (12.71 q/ha and 11.70 q/ha, respectively). The increase in seed yield in F3 and F2 were 26.9% and 25.5%, respectively over control (F0). Among the various planting geometry, the highest gross return (Rs 117240/ha), net return (Rs 71334/ha) and benefit cost ratio (2.54) were recorded from S3 and lowest gross return (Rs 106960/ha), net return (Rs 60304/ha) and benefit cost ratio (2.29) from S1. In respect of nutrient management the maximum gross return (Rs128053/ha), net return (Rs 80877/ha) and benefit cost ratio (2.72) were associated with F3 and lowest from F0 (Rs 93360, Rs 48058 /ha 2.06, respectively). The interaction effect of S3 and F3 gave highest crude protein yield (397.75 kg/ha) which was 48.2 % higher than S1 and F0 (205.92 kg/ha).

Published: April 2023

Iran is considered one of the important centers of diversity of the Persian clover. In order to introduce the best populations for their marketing and sales, 48 accessions were collected from various parts of country and relationship between geographical distribution with ecological factors were studied. The results showed that the distribution of populations is mainly in the north, northwest and the center of country. Altitude and rainfall are two important environmental factors in the distribution of this species. Also it can grow on a wide range of soils but does better on fertile heavy moist clays. It is suggested that the accessions of Persian clover that are grow and cultivated in the north and northwest of the country are more important in marketing in terms of favorable geographical conditions, which should be considered by marketers.
