Morphometry, Growth, and Condition of Hatchery-Reared Cisco ( Coregonus artedi ) and Bloater ( Coregonus hoyi)
Authors: Chalupnicki Marc , Mackey Gregg E. , McKenna James Edward , Johnson James H , Ketola H. George
Published: August 2023

The re-introduction of native species that have been extirpated or in
low abundance in the Great Lakes has been a binational initiative
between the United States and Canadian governments. Recently, new
management programs have been unway that use current hatchery facilities
for the restoration of native forage fishes in Lake Ontario. These
species include Bloater ( Coregonus hoyi), which has been extirpated
from Lake Ontario for approximately four decades, and Cisco ( C.
artedi), which exists at a fraction of its former abundance. We assessed
morphometrics, length-weight relationships, and condition factors during
early life development for eight cohorts of Cisco and Bloater reared
during 2012-2019. Weekly samples for Cisco and Bloater were measured
from hatch until release (29-45 weeks, 133-1,002 samples annually). Head
width, gape, mandible length, and mouth height metrics were all larger
for Cisco than Bloater at any given size but increased at similar rates
for both species. Average condition factors for Cisco and Bloater were
0.54317 and 0.55892, respectively. his information may also improve
field identification of these species, helping managers evaluate the
relative success of different release strategies for rehabilitation of
populations of these native species.
INDIVIDUAL COORDENATIVE STRUCTURES DURING SINGLE-LEGGED STANCE PRESENT LATERAL ASYMMETRY
Authors: Rinaldin Carla , Silva Verônica Andrade da , Campos Daniel Prado de , Manffra Elisangela
Published: August 2023

The study investigated the coordination of joint and segmental angles
for preferred (right) and non-preferred (left) lower limb movement for a
single-legged postural task. Nineteen healthy youngers (8 women and 11
men), aged between18-40 years (M = 25.11 years, SD = 6.61), the mean
height of 169.30 cm (SD = 10.23), mean weight of 71.18 kg (SD =16.87)
participated in this experiment. The angular variability was assessed by
analyzing the first and second principal components. The
crosscorrelation between the principal components and the angles showed
that specifically the thorax and pelvis segment, as well as the neck and
spine joints, participate actively in the coordination of postural
control during single-legged stance. As a main result, it was found that
the coordinative structures differ between preferred and non-preferred
lower limbs, but show high inter-subject variability (among
participants) in the angular and segmental coordination strategies
adopted to maintain unipodal postural control. Findings show that
intersubject variability represents motor abundance, which prioritizes
various kinematic solutions through joint and segmental degrees of
freedom to maintain vertical postural control. Intersubject variability
may be an underlying mechanism of laterality that takes advantage of
kinematic motor abundance.
Transnational relations and world politics: New approach
Authors: Bejker Ruzbeh
Published: August 2023

The past forty years has seen a marked increase in the proliferation of
transnational actors in the international system. The rise of these actors
has sparked a continuing debate within the field of international relations
on how they influence state action. This emergent literature on
?transnational studies? within international relations has mainly pitted
advocates of an approach that views states as the dominant force in world
politics versus those who see the rise of transnational actors as empirical
proof that the primacy of states as actors in the international system is
being replaced. New literature in the mid-1990s tried to move transnational
studies beyond these debates of the past. What both sides failed to grasp
was that, because both looked to how transnational actors could affect
domestic state behavior, they really in the end shared the same research
question (it was only their approach to the question that differed). The
result is a thin account of how transnational actors matter and a series of
measurement problems due to the underlying concepts being much too general.
This article introduces a new theoretical framework for testing the ability
of transnational actors to influence domestic state behavior.
Serbia’s foreign policy and relations with Russia as one of the priorities
Authors: Prorokovic Dusan
Published: August 2023

Although Republic of Serbia (Serbia) does not have an adopted foreign policy
strategy, there are a number of elements that are consistently applied. one
of them is the insistence on prioritizing cooperation with Russia.
Serbian-Russian relations have become stronger and deeper over the past 20
years, and they are unlikely to be impacted by changes in the global
environment that occur after February 2022. This paper tackles the subject
of continued Serbian-Russian relations and their dynamics, in addition to
analyzing the development of Serbia?s foreign policy and explaining how
relations with Russia became a priority. The analysis of the bilateral
relations between the two states is done by relying on structural realism as
a theoretical framework, first of all on considering the principle of
self-help as one of the key factors when determining foreign policy. The
methodological framework is based on discourse analysis, content analysis,
but also the use of the comparative method, induction and deduction methods.
Reflections of Women Standard Setters in the United States
Authors: Baudot Lisa , Convery Amanda M. , Kaufman Matt
Published: August 2023

SYNOPSIS

Motivated by trends toward gender equality on standard-setting boards in the United States, this study interviews women members of the FASB, GASB, and EITF to understand the factors critical to their successful nomination and appointment. Semistructured interviews were conducted with women standard setters to root our understanding in their own experiences and perceptions. Value emerged as a generalizing theme. Participants perceived value to the board in nomination as associated with professional expertise and ties with professional societies. Most participants perceived value in giving back to the profession by serving as a voice for an important stakeholder group as a critical factor for acceptance. Women standard setters consistently downplay the idea that diversity, equity, and inclusion represent primary decision criteria for board membership. Instead, their reflections imply that it is up to the profession to implement practices that promote the advancement of the most competent professionals from all backgrounds.

Thinking Like an Auditor: Evaluating Information to Arrive at Evidence-Based Conclusions
Authors: Allen Robert D. , Gramling Audrey A. , Hermanson Dana R.
Published: August 2023

SYNOPSIS

The sources of information today are quite varied and often conflicting, leading to claims of fake news, conspiracy theories, outright lies, and censorship. In such an environment, how do you work toward evidence-based conclusions, or truth when possible? In this paper, we discuss the Auditing Standards Board (ASB)’s Audit Evidence Framework (AEF) and recent Public Company Accounting Oversight Board evidence-related guidance as valuable tools to help auditors and others evaluate the information they might use to arrive at evidence-based conclusions. We encourage others to “think like an auditor” when evaluating information. Our fundamental message is that information is not automatically evidence that should be used to support conclusions. Instead, information needs to be carefully evaluated before it rises to the level of evidence to support a conclusion.
Los juzgados de paz de la ciudad de Buenos Aires. Entre los límites de las parroquias y un marco territorial propio (1821-1839)
Authors: Gastellu Sofía
Published: August 2023

Los Juzgados de Paz de la ciudad de Buenos Aires fueron creados en 1821 durante el proceso de reformas llevado a cabo por Bernardino Rivadavia. Sus primeras jurisdicciones fueron parroquiales, estableciendo un juez de paz por cada parroquia de la ciudad. A partir de 1839, sus límites fueron modificados durante el segundo gobierno de Juan Manuel de Rosas, otorgando a los jueces de paz un marco territorial propio como autoridad local de baja justicia. Nuestra propuesta es revisitar la dimensión territorial de la justicia de paz problematizando su relación con las parroquias, las comisarías y los cuarteles –así como las diferentes autoridades locales– con el propósito de establecer por qué se produjo la separación de los límites civiles y eclesiásticos. Explorar el equipamiento político del territorio de la justicia de paz y analizar las modificaciones del rosismo puede proporcionar nuevas miradas sobre un viejo problema: la influencia de la arquitectura político-institucional heredada de la década de 1820 en las medidas de gobierno que el rosismo implementó en la ciudad de Buenos Aires.
Gobernar la ciudad: justicia de paz, jefatura política y municipalidad. Rosario (Santa Fe, Argentina) 1858-1872
Authors: de los Ríos Evangelina
Published: August 2023

El presente artículo examinará los cambios políticos y administrativos que se sucedieron en la ciudad de Rosario a partir de la instalación del cuerpo municipal. Se mostrará que su creación formó parte de un proceso de equipamiento político a partir de una compleja variedad de instituciones (Jefatura Política, Jefatura de Policía, Juzgado de 1ra Instancia, Comisarías, Tribunal de Comercio, etc.) que redefinió la administración y modificó la estructura institucional del gobierno local. Las preguntas que guían la investigación son: ¿Cómo se gobernaba la ciudad? ¿Qué significó para la administración local la creación de la municipalidad? ¿Qué impacto tuvo su instalación en la dinámica política? ¿Cuál fue su injerencia a nivel local?
Edad de menarquia y bienestar en mujeres de Valparaíso, Chile (1851-1895): un análisis histórico antropométrico
Authors: Lacueva Muñoz Jaime , Arancibia Martini Héctor , Pastén González Benjamín , Villarroel Durán Juan , Santibáñez Garviso Johanna
Published: August 2023

La menarquia señala el inicio del periodo reproductivo y constituye un importante marcador del crecimiento humano femenino. La edad en la que se presenta depende de la interacción de factores genéticos y socioambientales, por lo que resulta un interesante indicador del bienestar biológico de las poblaciones. Con una muestra inicial de 445 mujeres residentes en Valparaíso y nacidas entre los años 1851-1895, evaluamos la incidencia de factores socioambientales en la edad de la menarquia en un contexto histórico caracterizado por un fuerte incremento del Producto Interno Bruto y un intenso, pero inarmónico desarrollo urbano. Aunque los resultados muestran una tendencia al adelanto de la edad de menarquia, este no resulta estadísticamente significativo (p > .05). El origen rural/urbano, el tamaño familiar y el estrés intrafamiliar no parecen incidir en la edad de menarquia de la población de la muestra. El fenómeno de penalización urbana podría explicar en parte los resultados.
Pereira futura. La proyección de una ciudad moderna en Colombia, 1930-1938
Authors: Correa Ramírez Jhon , Gil Pérez Anderson
Published: August 2023

Este artículo analiza el proceso histórico de construcción de la idea de futuro en las preocupaciones de las élites de la ciudad de Pereira en Colombia durante la década de los años treinta y su implicación en la proyección de la urbe moderna. Se revisaron fuentes hemerográficas locales como El Diario, S.M.P y Panoramas. Como resultado se obtiene que las élites locales planearon el futuro de Pereira a partir de una concepción crítica de la ciudad en la que se valoraba el rápido desarrollo urbano alcanzado en pocas décadas desde la fundación en 1863 y, al mismo tiempo, se mostraba a la ciudad como un proyecto inacabado que necesitaba recorrer el camino del progreso material, infraestructural y cultural. Así mismo, se concluye que las élites de la ciudad tuvieron una preocupación reiterada por la Pereira futura que se enmarcó en proyecciones realizables que se fundamentaron en un alto nivel de autoconfianza, el liderazgo de las asociaciones voluntarias de la sociedad civil y en la convicción en el progreso.
To år i FNs sikkerhetsråd har styrket norske interesser
Authors: Huitfeldt Anniken
Published: August 2023

I denne artikkelen belyser utenriksminister Anniken Huitfeldt tre ulike aspekter ved Norges arbeid og profil i FNs sikkerhetsråd. For det første: Effekten av det toårige medlemskapet for norsk utenrikspolitikk og norske interesser. Hva har Norge fått igjen? For det andre: Hva har Norge bidratt med? Har Sikkerhetsrådet tjent på å ha Norge som valgt medlem? For det tredje: Hvilke diplomatiske og utenrikspolitiske særtrekk ved Norge har hatt betydning for vår rolle og innsats som valgt medlem av FNs sikkerhetsråd? Utenriksministeren viser i artikkelen hvordan sikkerhetsrådsmedlemskapet har styrket norske interesser. Huitfeldt gir flere eksempler på hvordan Norge som valgt medlem utnyttet handlingsrommet i Sikkerhetsrådet ved både å være en prinsippfast aktør, men samtidig ta initiativ og lede flere forhandlinger som førte frem til viktige sikkerhetsrådsvedtak. Hun understreker hvor viktig begge disse rollene ble etter Russlands fullskala angrepskrig mot nabolandet Ukraina 24. februar 2022. Det ble da helt avgjørende å hindre at Sikkerhetsrådet endte opp i fullstendig handlingslammelse, særlig på saksområder som ikke hadde noen sammenheng med angrepskrigen mot Ukraina.
Abstract in English:Two Years in the UN Security Council Has Strengthened Norwegian InterestsIn this article, Foreign Minister Huitfeldt presents three features of Norway’s diplomacy during its two-year period as an elected member in the UN Security Council. Firstly, how has the UN Security Council membership affected Norwegian foreign policy and interests? Secondly, what have been Norway’s main contributions to the Council’s work? And thirdly, what have been the clear hallmarks to Norway’s efforts and diplomacy in the Security Council? Furthermore, the Foreign Minister argues how the Security Council membership has strengthened Norwegian interests. Huitfeldt provides several examples on how Norway, as an elected member, utilised the scope for action in the Council, and combined a principled voice with pragmatic diplomacy that led to concrete results in terms of adopted resolutions and statements. She emphasises the importance of this problem-solving approach, particularly after Russia started its full-scale invasion of Ukraine 24 February 2022. It was then crucial to avoid a complete paralysis of the Council, especially in dossiers not connected with Russia’s war of aggression against Ukraine.

It is demonstrated that in keeping the conditions of storage of fresh fuel, as well as the recommendations of the present work, its high corrosion resistance and operability in further operation is ensured.
Model and method of solid household waste sorting for their effective thermal disposal
Authors:   Odesa Polytechnic National University, Lysiuk Hanna , Maksymova Oksana ,   National University "Odesa Maritime Academy"
Published: August 2023

The work considers the development of a simulation model and an automated method of sorting solid household waste based on the identification of a portion of the studied raw material with further classification according to accepted groups of characteristic chemical composition. A method of classification of municipal solid waste (MSW) and a method of their identification was proposed, which made it possible to identify groups that produce acid gases. The basis of the method is a simulation model, which is represented by a tabular form of the gross formulas of possible compounds. The identified compounds are identified both qualitatively by the isoenthalpic method and quantitatively by the express gravimetric method. The sequential chain of identification makes it possible to search for substances that form acid gases during further processing by thermal destruction methods. A method of sorting solid household waste has been developed for the possibility of further processing of each group with maximum efficiency and compliance with ecological indicators. The method is based on: technological method of sorting; the method of sorting raw materials-processing in which measuring devices are integrated to ensure the specified characteristics of identification according to the classification features of the simulation model; the principle of using measuring devices depending on the type of identification task by qualitative or quantitative indicator.

Published: August 2023

Mobile robots control systems achieve greater efficiency through the use of robust environmental analysis algorithms based on data collected from optical sensors such as depth cameras, Light Detection and Ranging sensors (LIDARs). These data sources provide information about control object environment in point cloud. The work of such algorithms, as a rule, is aimed at detecting the objects of interest and searching for the specified objects, as well as relocating its own position on the scene. There are many different approaches for solving object detection problem in point clouds, but most of them require high computational resources. In this work, many variations of the random sample consensus (RANSAC) method are analyzed for objects defined by a mathematical model of an analytical form. Statistical characteristics of data analysis were used to compare the methods. The results demonstrate the most energy efficient flat surface detection method that processes 60 RGB-D camera frames per second.
Biochar: Pemanfaatan dan Aplikasi Praktis
Authors: Evizal Rusdi , Prasmatiwi Fembriarti Erry
Published: August 2023

Biochar is a carbon-rich solid produced from the pyrolysis of biomass such as wood, manure, and leaves under high temperature and low oxygen conditions which is used for agricultural applications as a soil amendment. This paper reviews the utilization and practical application of biochar. The application of biochar into the soil can improve the physical, chemical and biological properties of the soil, namely increasing porosity, water holding capacity, soil aggregation, increasing pH, cation exchange capacity, soil organic carbon, nutrient retention and availability, and increasing microbial life, meso and soil macrofauna. Aside from being a soil amendment, biochar has a function on issues of global warming, climate change, and the environment, namely its role in carbon sequestration and stabilization, greenhouse gas emissions, and soil pollutant remediation. If biochar is applied properly, namely using the right feedstock materials, method of manufacture, dosage, method of application, and place, it will affect agronomic performance and crop yields. Reduced yields are mostly occured in temperate climates as biochar significantly increases soil pH causing an effect of excessive liming resulting in immobilization of key nutrients such as Mg, Fe, B, and P. Biochar needs to be mixed or applied together with fertilizer ingredients such as chemical fertilizers, bio-fertilizers, compost, and manure. Another effort is to enrich biochar with those materials so that biochar is categorized as a biochar-based fertilizer that has a higher selling price. Key words : Application, biochar, benefit, method, crop yield

Published: August 2023

AbstrakPenelitian ini bertujuan mengkaji konsep kemiskinan sebagai deprivasi kapabilitas dari pemikiran Amartya Sen dalam upaya pemberdayaan masyarakat miskin di Papua. Metodologi yang digunakan ialah analisis wacana kritis. Penelitian ini menemukan bahwa pemikiran Sen sesungguhnya adalah sebuah alternatif kritis terhadap beragam wacana dan teori ilmiah yang kerap mengidentifikasi masalah kemiskinan sebagai kekurangan dalam pencapaian komoditas tertentu. Padahal teori-teori tersebut berbeda dengan standar universal dan standar masyarakat bersangkutan. Oleh karena itu, konsep pemikiran Amartya Sen sangat relevan untuk memahami kasus kemiskinan di daerah Papua dan Papua Barat dalam upaya pemberdayaannya. Sebab masyarakat Papua dan Papua Barat hidup di daerah yang secara sumber daya terbilang kaya, tetapi masyarakatnya kehilangan hak dan askesnya untuk mengolah dan memberdayakan sumber daya alamnya. Akibatnya terjadi deprivasi kemampuan personal dan aspirasi kepentingan sosial-politik masyarakat Papua dan Papua Barat.Kata kunci; Deprivasi, Ekonomi, Kapabilitas, Kemiskinan, Papua dan Papua BaratAbstractThis study aims to examine the concept of poverty as a capability deprivation from Amartya Sen's thoughts about efforts to empower poor communities in Papua. The methodology used is critical discourse analysis. This research finds that Sen's thinking is a critical alternative to various scientific discourses and theories that often identify the problem of poverty as a deficiency in the attainment of certain commodities. Even though these theories are different from universal standards and the standards of the community concerned. Therefore, Amartya Sen's concept of thought is very relevant for understanding cases of poverty in the regions of Papua and West Papua and efforts to empower them. Because the people of Papua and West Papua live in areas that are relatively rich in resources, but the people lose their rights and access to process and empower their natural resources. The result is the deprivation of personal abilities and aspirations of the socio-political interests of the people of Papua and West Papua.Keywords: Deprivation, Economy, Capabilities, Poverty, Papua and West Papua.
Time-Dependent Reliability Analysis for Deflection of a Reinforced Concrete Box Girder Bridge
Authors: TAREKEGN Abrham Gebre
Published: August 2023

Prior to casting of concrete, proper supervision and attention to camber provision in bridge construction are required. It is also critical to use an appropriate quality control manual, pay due attention to reinforcement bar placement, and have a high level of formwork design before construction begins. If these issues are not properly addressed, performance of structures will be affected. In this research, performance of a 40.5m box-girder reinforced concrete bridge which was constructed without having proper camber is studied. As camber was the most important issue of the bridge under investigation, the impact on strength and serviceability requirements is compared to the standard. A dynamic load test with an Arduino type accelerometer is performed to assess the bridge's current condition in relation to the serviceability limit requirement. The deterioration of reinforced concrete (RC) sections due to reinforcement corrosion, creep, and an increase in load intensity, as well as the corresponding statistical distributions are considered to estimate the long-term effect of bridge deflection. The time-variant analysis results show that a linear decrease in deflection reliability indices with the bridge's expected service life of 58 years and strengthening it increased to 85 years.

Authors: Tanjung Yul Ifda , Irfandi Irfandi , Sudarma Teguh Febri , Lufri Lufri , Asrizal Asrizal , Hardeli Hardeli
Published: August 2023

Constructivism in learning is a philosophy that holds where the process of forming knowledge in individuals is the result of mental activity supported by the process of learning experience. Many studies have been conducted on the effect of constructivism theory on learning outcomes, but few have quantifies the effect so that it can be analyzed qualitatively. Therefore,  the purpose of this research was to quantify the effect size of the relationship between constructivism theory and student learning outcomes using meta-analytic research and data analysis techniques with openMEE software. Data was collected from Scopus and Google Scholar for 17 articles published in 2019 till 2022. Based on the analysis, In terms of the effectiveness of constructivism learning theory, an estimated data of 1.548 is obtained which indicates that constructivist theory has great effectiveness in improving student learning outcomes. In addition, the effect size measurement at the primary and secondary levels of education indicates that the student is in high category. This explains why constructivism learning is very well implemented because children at this level are already able to be encouraged to construct their own knowledge which influences their learning outcomes.

Recently, crimes of sexual abuse against children have often occurred. Sex crimes among children stem from a number of circumstances, such as pornographic shows that are easily accessible recently, as well as the inability of victims of harassment to report perpetrators of sexual crimes that occur to children. Victims who were victimized did not dare to sue the perpetrators. The problem in this article is how the author views the role of the victim in sexual crimes. The methodology used in this review includes the use of a qualitative appr oach using sources from literature reviews, such as those related to the topics discussed. The conclusion from this study is that some child victims of sexual abuse may also have no clear symptoms. The effects of sexual harassment are very serious and can manifest in a variety of pathological symptoms and behaviors. There is almost no area of general symptoms that is not related to a history of sexual abuse. Age and various abuse-related factors can influence the nature and severity of symptoms.

Coffee is a stimulant crop with high socio-economic cultural value including economical significance in Ethiopia. This study was conducted in 2019-2020 to investigate the effect of harvesting methods and drying surfaces on the physical quality of the coffee beans. The experiment was carried out with two factors, harvesting methods and drying surfaces laid out in a two factorial completely randomized block design with three replications using a landrace coffee variety. The result showed that the interaction of harvesting methods and drying surfaces was highly significant (P<0.01) for coffee bean size and dried coffee berry weight. The highest beans retained above screen were recorded from the interaction of mesh wire (90%) and cemented drying (89%) surfaces with selective harvesting methods. The highest dried coffee berry weight (69.33 gm) were attained from the interaction of selective harvesting with mesh wire drying surfaces. The lowest dried coffee berry weight (63.79 gm) were attained from the interaction of strip harvesting with tin drying surfaces. Significant (P<0.05) variation for primary defects, length of drying period were recorded. Higher length of drying periods (41.67 days) was recorded from the interaction of mesh wire drying surfaces with selective harvesting method and the lowest (20.33 days) was recorded from the interaction of tin drying surfaces with strip harvesting method. The highest percentage of primary defected beans were recorded from the interaction of selective harvesting methods with mesh wire drying surfaces (15%) and the lowest number were recorded from strip harvesting method with drying on plastic (5%). Therefore, it can be concluded that using the interaction of selective harvesting and drying on mesh wire is better for optimum physical quality of coffee in the studied area

An experiment was carried out to evaluate an advance breeding line of tuberose double type IIHR-4 along with check for flowering, yield and resistance to root knot nematode and Alternaria leaf burn disease. The hybrid selection IIHR-4 was developed through hybridization by crossing Mexican Single x Pearl Double, followed by selection. Double type tuberose IIHR-4 was found to be novel with better flowering and quality traits such as short spike (62.00 cm), rachis length (25.59cm), diameter of floret (4.47cm) and number of florets per spike (50.75). The spikes of IIHR-4 exhibited more number of florets open at a time in spike (7.10) with the shorter internodal length of 3.45cm. The florets are with shorter length (5.22cm) arranged very compactly on the spike making IIHR-4 ideal as cut flower. IIHR-4 was found to be highly resistant to root knot nematode Meloidogyne incognita under field conditions and tolerant to Alternaria leaf burn disease.

Four F1 hybrids of arabica coffee (Coffea arabica L.) developed with the primary objective of pyramiding the SH3 gene for leaf rust resistance in a commercial variety ‘Chandragiri’ for achieving the long-lasting resistance to leaf rust, have been evaluated in field. Two hybrids (S.5083 and S.5084) were derived from a donor heterozygous to SH3, while the other two hybrids (S.5085 and S.5086) were developed from donor homozygous to SH3. Among the hybrids, S.5086 recorded superior yield performance during individual years with a maximum yield of 1611 kg/ha during 2020-21 and the four year mean yield of 1313 kg/ha. The hybrid exhibited maximum heterosis over mid parent (29.10%) and better parent (17.12%) and S.5086 progeny also manifested high field tolerance to leaf rust pathogen as the entire plant population was free from the disease incidence throughout the study period. The findings of the present study established the efficiency of F1 breeding strategy with simultaneous pyramiding of rust resistance genes for development of vigorous, high yielding and durable rust resistant F1 hybrids in arabica. The F1 hybrid, S.5086 with promising performance in terms of crop yield and high field tolerance to leaf rust has potential implications for commercial exploitation.

An experiment was conducted to estimate the genetic variability of 15 indigenous and exotic squash genotypes assessing 18 quantitative and 8 qualitative traits. Results showed that the accessions have high variability in qualitative traits like fruit size, fruit shape, fruit skin colour,lustre and fruit productivity, which allowed selection for considerable gains in these characteristics. The quantitative traits such as fruits yield per plant, fruit weight, length, diameter and total yield per hectare showed the greater phenotypic coefficient of variation (PCV) along with higher heritability which can helps to identify desirable genotypes. The obtained significant and positive correlation between fruit yield with number of leaves, nodes, fruit length, weight and number could assist in selection to improve this crop. Cluster analysis resulted in the formation of 4 groups, confirming the genetic variability among the studied genotypes. Eventually, the attained PCA analysis result revealed that the number of fruits per plant, fruit yield per plant, fruit length and days to first female flowering are the most discriminating traits which are accelerating the variability in squash genotypes. On the basis of the yield and its attributing traits, First Runner is the best genotype suited in this environment.

Giant Himalayan lily (Cardiocrinum giganteum Wall.) is a perennial bulbiferous herb of Liliaceae and an endemic species in the eastern Himalayan region, which has become one of the new flower crops because of its high ornamental value. The present investigationwas conducted to study pollen morphologyi.e., fresh pollen grains size was measured in different media, viz., water, acetocarmine, glycerol and without any medium (dry). The pollen grains of Giant Himalayan lily exhibited the average size (length x width) of (22.64 x 19.72μ) in water suspension. The result revealed that in glycerine and dry condition shape of pollen grains was perprolate. However, in water and acetocarmine it looked was round in shape. The result also shown that highest pollen germination (54.70%, 63.69%) and pollen tube growth (89.24μ, 175.85μ) in 10% sucrose solution for 12 hours and 24 hours respectively. In control light treatments, red light was found to be best in pollen germination and pollen tube growth.

Field experiments were conducted in mango for four years during 2017-2020 at ICAR-Indian Institute of Horticultural Research to standardise optimum soil volume wetting for drip irrigation. Wetting soil volume upto 70% recorded higher mean fruit yield of 34.8 kg/plant (9.68 t/ha)and with further increase in the level of soil volume wetting irrigation (upto 80%), there was a decline in the mango yield (7.40 t/ha). Similarly, significantly increased response was observed in fruit weight upto 70% soil volume irrigation (226 g) although there were no significant differences in the TSS of the fruit. Significantly higher water use efficiency was observed for 30% soil volume wetting irrigation (274.1 kg/m3) and further no significant differences were observed in water use efficiency between 50% and 70% soil volume wetting irrigations indicating that in areas of water scarcity, it is enough to scheduling the irrigation only upto 50% soil volume wetting in mango for economising the water (232.1 kg/m3).
