THE DARK SIDE OF SPORT: MANAGERIAL BULLYING AND HARASSMENT CHALLENGES IN DIFFERENT TYPES OF SPORTS
Authors: Vveinhardt Jolita , Fominienė Vilija Bitė , Andriukaitienė Regina
Published: September 2020

Bullying and harassment are the dark side of sport, not open to spectators and often ignored by coaches and leaders. Therefore, the research aim is to identify prevalence of bullying and harassment in Lithuanian organized sport with regard to individual, combat and team sports, highlighting measures/actions used to manage these phenomena. Survey research uses quantitative research strategy. The study involved 1440 organized sports athletes representing all sports types. The prevalence of bullying actions with regard to separate type of sports was identified: in individual sports (9.8%), in combat sports (8.5%), and in team sports (7.3%). The analysis by four specific actions has shown that athletes experienced most of such actions in combat sports (20%); almost half less, in team sports (10.8%) and individual sports (10.1%). The results of the study show a lack of bullying and harassment intervention and of comprehensive complaint submission procedures, while coaches particularly often ignore athletes’ negative behaviour. The article discusses managerial causes of bullying and harassment in the sports organization, presenting a holistic view of the phenomenon, including the forms of violence that have been little studied so far. This will help leaders to carry out prevention and intervention activities the specificity of which comes to prominence depending on the types of sports.
Using Machine Learning to Find Ghostly Damped Lyα Systems in the SDSS DR14
Authors: Fathivavsari Hassan
Published: September 2020

We report the discovery of 59 new ghostly absorbers from the Sloan Digital Sky Survey Data Release 14. These absorbers, with z
abs ∼ z
QSO, reveal no Lyα absorption, and they are mainly identified through the detection of strong metal absorption lines in the spectra. The number of such previously known systems is 30. The new systems are found with the aid of machine-learning algorithms. The spectra of 41 (out of total of 89) absorbers also cover the Lyβ spectral region. By fitting the damping wings of the Lyβ absorption in the stacked spectrum of 21 (out of 41) absorbers with relatively stronger Lyβ absorption, we measured an H i column density of log N(H i) = 21.50. This column density is 0.5 dex higher than that of the previous work. We also found that the metal absorption lines in the stacked spectrum of the 21 ghostly absorbers with stronger Lyβ absorption have similar properties as those in the stacked spectrum of the remaining systems. This circumstantial evidence strongly suggests that the majority of our ghostly absorbers are indeed DLAs.
An Alternative Interpretation of Impulsive SEP Events Occurring on 1999 January 9–10
Authors: Tan Lun C.
Published: September 2020

We have examined two impulsive solar energetic particle events that occurred on 1999 January 9–10 (earlier event A and later event B). Both events showed earlier velocity dispersion and later intensity dropout of ions. In particular, in event A, the dropout repeated five times. Through the onset time analysis of solar particles, we find that only at higher energies (>0.2 MeV nucleon−1 for heavy ions and >2.8 keV for electrons) can the analysis provide a consistent path length of ions and electrons. The path length in event A is larger than that in event B. In contrast, at lower energies, the analysis fails to predict the distribution of first arrival of solar particles. The divergence between observation and prediction would increase if the interplanetary scattering of ions were taken into account. We then focus on the lower-energy region, where a negative correlation of ion intensities with plasma β is displayed. We have found that the repeated dropout of ions can be caused by the magnetic reconnection acceleration in the solar wind. In addition, we have discovered an isolated proton dropout event in which a sharply anisotropic pitch-angle distribution of low-energy electrons is also seen. Our observation is consistent with the prediction of Tautz et al. that a minimum power spectral density component parallel to the magnetic field can reduce the magnetic mirroring effect, preventing electron scattering through 90°.
Tests of AGN Feedback Kernels in Simulated Galaxy Clusters
Authors: Glines Forrest W. , O’Shea Brian W. , Voit G. Mark
Published: September 2020

In cool-core galaxy clusters with central cooling times much shorter than a Hubble time, condensation of the ambient central gas is regulated by a heating mechanism, probably an active galactic nucleus. Previous analytical work has suggested that certain radial distributions of heat input may result in convergence to a quasi-steady global state that does not substantively change on the timescale for radiative cooling, even if the heating and cooling are not locally in balance. To test this hypothesis, we simulate idealized galaxy cluster halos using the ENZO code with an idealized, spherically symmetric heat input kernel intended to emulate. Thermal energy is distributed with radius according to a range of kernels, in which total heating is updated to match total cooling every 10 Myr. Some heating kernels can maintain quasi-steady global configurations, but no kernel we tested produces a quasi-steady state with central entropy as low as those observed in cool-core clusters. The general behavior of the simulations depends on the proportion of heating in the inner 10 kpc, with low central heating leading to central cooling catastrophes, high central heating creating a central convective zone with an inverted entropy gradient, and intermediate central heating resulting in a flat central entropy profile that exceeds observations. The timescale on which our simulated halos fall into an unsteady multiphase state is proportional to the square of the cooling time of the lowest-entropy gas, allowing more centrally concentrated heating to maintain a longer-lasting steady state.
Detection of the Occultation of 55 Cancri e with TESS
Authors: Kipping David , Jansen Tiffany
Published: September 2020

55 Cancri e is an ultra-short period transiting Super-Earth observed by TESS in Sector 21. Using this photometry, we measure the occultation depth in the TESS bandpass, leveraging the precise transit light curve and comparing multiple detrending methods. We measure the occultation depth to be (15.0 ± 4.8) ppm—a staggeringly small change in brightness, yet one detected by TESS in just a single sector of data. This implies a brightness temperature of

K, which is around 1.5σ greater than expected given the mean depth measured with Spitzer. This is not a formally significant difference, and may be accounted for by the known variability, or by an albedo of ∼0.5. In any case, future TESS observations of this system will provide an exciting opportunity to further study this diminutive world’s atmosphere.
Mapping the natural heritage as a source of recreation services at national scale in Bulgaria
Authors: Ihtimanski Ivo , Nedkov Stoyan , Semerdzhieva Lidiya
Published: September 2020

Natural heritage includes natural features or natural areas of outstanding universal value. At a national level, this value refers to the importance of ecosystems which can be considered as the spatial units representing the natural heritage of the particular area in terms of their values to people. Nature-based outdoor recreation represents an important service that interests millions of people and contributes to connecting them to nature, but it may also cause negative impacts in the form of pollution, erosion and habitats loss. We apply the ESTIMAP recreation model which provides a framework for a spatially-explicit assessment of local outdoor recreation and use it to identify and assess the natural heritage as a source of recreation services at a national level in Bulgaria. At the first stage of the study, we identify the natural heritage and the data sources to represent it in a spatially-explicit way. Then, we apply the module for recreation potential to assess the potential of the natural heritage to provide a recreation ecosystem service. At the third stage, the accessibility of the natural heritage is assessed in order to specify how the potential identified at the previous step can be really used. Finally, the recreation potential and accessibility are integrated into the recreation opportunity spectrum in order to develop the maps representing the ecosystem service supply provided by the natural heritage. The results are presented in form of a recreation potential map that reveals the capacity of natural heritage to provide the recreation potential, map of the accessibility of the natural heritage and map of the recreation opportunity spectrum representing the combination between the first two maps. The maps will be used for the development of an innovative geospatial platform designed to facilitate the access of the Bulgarian natural heritage to the European common knowledge and innovation markets. The results on the accessibility and recreation opportunity spectrum contribute to the development of the model in areas which were not covered by previous applications at the EU scale.

The popularization of the STEM educational model has also brought along the need for well-trained teachers. In this model, it is aimed to understand examples in real world and solve related problems. Of course, this depends on the development of critical thinking, creative thinking, researching and experimental skills. For these reasons, in the study, the difficulties which the physics-chemistry preservice teachers encountered while preparing lesson plans in relation to STEM implementations and their opinions about the implementation of these plans. For this purpose, the preservice teachers were asked to form real life-related, information-based problems covering the acquisitions included in the high school programs and then they were expected to turn these into STEM lesson plans. The study is a descriptive study, one of the qualitative research methods. The data was collected via the forms developed by the researchers and including open-ended questions and one-to-one interviews. The obtained data was analyzed according to the steps of content analysis. When the analysis results were examined, it was found that the preservice teachers had difficulty in forming real life-related, information-based problems covering the acquisitions included in the high school programs and integrating them with scientific knowledge and in the engineering integration of STEM implementations and finding materials.

Enriching Organisational Knowledge of Corporate Social Responsibility From the Traditional African-Nigerian and Islamic Religion Perspectives
Authors: Raimi Lukman , Aljadani Abdussalam
Published: September 2020

This paper examines organisational knowledge of corporate social responsibility (CSR) from the African-Nigerian and Islamic Religion Perspectives in order to enrich the American-European perspectives, that have dominated the academic landscape. Exploiting the Hermeneutics Theory of Interpretation, this research adopts a qualitative research method by extracting new meanings and themes from non-Western texts and scholarly works on CSR. The paper found that CSR had long existed in the philosophies of Africans and Islam as Ubuntu, Omoluwabi, Communal Solidarity, Zakat, Sadaqat and Waqf. The African-Islamic perspectives of CSR correlate with the American-European perspectives that have dominated the academic landscape. The findings therefore demystified the widely-held view that CSR is a new organisational knowledge in Africa and the Muslim World. Rather CSR had been entrenched in the cultural norms of Africans and Muslims, although with different names. The paper has enriched organisational knowledge, by providing an integrated understanding of CSR across three perspectives.

The new digital technologies open the space for changing the way that business works creating new demands on information processing in organizations. Organization response to technological changes was enabled by information technology improvements and digital organizations should develop new capabilities that anticipate and respond to new opportunities in their business ecosystems. In the context of transformative trends driving with the information technology development, ubiquitous computing creates an environment where embedded processors, computers, sensors, and digital communication technologies are available everywhere. Further, the Internet-of-things creates a new form of networked computing where advanced applications intelligently monitor and control remote sensors, mobile devices, and smart machines. Along with the information technology development digital organizations need to develop operational technology in the same way. Thus, the process of convergence is needed, and it strongly depends on harmonization of information and operational technologies strategies.

Authors: Zammar Nisrine
Published: September 2020

The use of social media platforms has become an essential part of today's protocol of reacting to any sudden crisis, due to their interactive nature which allows them to reach vast and heterogeneous audiences. This makes them the right tool that enables the organizations to spread their messages efficiently. Any failure in responding adequately on social media level, would allow rumors and negative contents to circulate uncontrollably, affecting the organizational reputation and recovery. Therefore, the main purpose of this paper is to provide a clear understanding of the crisis communication strategy adopted by Dairy Khoury, a Lebanese firm, on social media, at a time when the new power of social media had not yet been fully measured and estimated. The author will highlight the necessity of a preset crisis communication strategy and the use of social media platforms while dealing with crisis.

The technology savvy connected consumers are constantly been updated through the extensive pool of information accessed by them on a daily basis. The purpose of this paper is to examine the impact of Digital Content Marketing on the Purchase Intention of connected consumers towards natural ingredient based personal care products. Furthermore, Perceived Trust is positioned as a mediator within the context of this study to enhance the understanding of whether Perceived Trust contributes to mediate the relationship between Digital Content Marketing and Purchase Intention. Moreover, the researcher also attempts to understand the age group differences for the relationship highlighted above. Data were collected from 469 respondents via a structured questionnaire and such data were analyzed through quantitative means using SPSS with the conclusion that the direct relationship between content marketing and purchase intention has been accepted while the impact of content marketing on purchase intention mediated by trust was also accepted. Moreover, it was found that age acts as a moderator within the mediated relationship of trust between content marketing and purchase intention while also acting as a moderator within the simple linear relationship between content marketing and purchase intention.
Improving olive mechanical harvesting using appropriate natural frequency
Authors: Alzoheiry Ahmed , Ghonimy Mohamed , Abd El Rahman Eid , Abdelwahab Ossama , Hassan Ahmed
Published: September 2020

The good performance of olive mechanical harvesting by shaking depends on the suitable values of limb vibrator operating parameters (frequency and amplitude). Mathematical models of a single degree of freedom (S.D.F.M) and two degrees of freedom (T.D.F.M) were used to estimate the natural frequency (FN) of olive fruit stem system. The results from these models indicated that the FN values were 33.9, 31.9, and 28.0 Hz for the full mature stage, half-ripe olive, and full-ripe olive respectively. Branch vibrator was operated at three levels of frequency 25, 30 and 35 Hz and 3 levels of amplitude 25, 30 and 35 mm at a vibration time of 10 s. Measurements covered the fruit removal percentage (FRP) and degree of full-ripe fruit selectivity (DS). The results showed that the maximum FRP value, 90.6%, was achieved at a frequency of 35 Hz and amplitude of 25 mm while the maximum DS value, 78.58%, was obtained at 25 Hz frequency and 25 mm amplitude.
Nutritional Considerations and Strategies to Facilitate Injury Recovery and Rehabilitation
Authors: Smith-Ryan Abbie E. , Hirsch Katie R. , Saylor Hannah E. , Gould Lacey M. , Blue Malia N. M.
Published: September 2020

Nutritional interventions are not commonly a standard of care in rehabilitation interventions. A nutritional approach has the potential to be a low-cost, high-volume strategy that complements the existing standard of care. In this commentary, our aim is to provide an evidence-based, practical guide for athletes with injuries treated surgically or conservatively, along with healing and rehabilitation considerations. Injuries are a normal and expected part of exercise participation. Regardless of severity, an injury typically results in the athlete's short- or long-term removal from participation. Nutritional interventions may augment the recovery process and support optimal healing; therefore, incorporating nutritional strategies is important at each stage of the healing process. Preoperative nutrition and nutritional demands during rehabilitation are key factors to consider. The physiological response to wounds, immobilization, and traumatic brain injuries may be improved by optimizing macronutrient composition, caloric consumption, and nutrient timing and using select dietary supplements. Previous research supports practical nutrition recommendations to reduce surgical complications, minimize deficits after immobilization, and maximize the chance of safe return to play. These recommendations include identifying the individual's caloric requirements to ensure that energy needs are being met. A higher protein intake, with special attention to evenly distributed consumption throughout the day, will help to minimize loss of muscle and strength during immobilization. Dietary-supplement strategies may be useful when navigating the challenges of appropriate caloric intake and timing and a reduced appetite. The rehabilitation process also requires a strong nutritional plan to enhance recovery from injury. Athletic trainers, physical therapists, and other health care professionals should provide basic nutritional recommendations during rehabilitation, discuss the timing of meals with respect to therapy, and refer the patient to a registered dietitian if warranted. Because nutrition plays an essential role in injury recovery and rehabilitation, nutritional interventions should become a component of standard-of-care practice after injury. In this article, we address best practices for implementing nutritional strategies among patients with athletic injuries.

Published: September 2020

Background:

Contemporary management of patients with atrial fibrillation (AF) indicates the need for educational and self-care programs to address lifestyle factors.

Aims:

This study examined the clinical need and interest in programming for risk factor modification in AF patients residing in a mostly rural area.

Methods:

Participants with AF (n = 86) were recruited during university-based cardiac electrophysiology appointments and asked to complete a 10-min survey battery assessing a range of risk factors spanning physical activity, knowledge, ability, interest, and engagement, as well as psychologic function.

Results:

AF risk factor reports indicated broad potential need for AF programming with an average CHADS-VASC of 3.8, with approximately 67% reporting low physical activity, and 38% significant anxiety. Related to self-care topics, education on physical activity was the highest-rated program, but weight-loss programming was rated as the most likely to attend. Distance to the clinic was the most often cited barrier, 50% of sample.

Conclusions:

AF patients demonstrated a need and view educational programming in the realm of physical activity and weight-loss as desirable. Increased research is needed to determine format and duration of treatment deemed efficacious and able to overcome specific barriers such as distance to care.
The Role of Brain-Derived Neurotrophic Factor and Serotonin Polymorphisms in Stress-Related Personality and Psychiatric Symptoms
Authors: Nestor Paul G. , Lapp Hannah E. , Boodai Sara B. , O'Donovan Keira , Hasler Victoria Choate , Hunter Richard
Published: September 2020

Background: Diathesis-stress perspectives of cardiovascular (CV) health and disease have long identified the important role of a host of mental health risk and protective factors in both illness course and recovery. Few studies, however, have investigated these factors within the same sample of healthy people. Aims and Objectives: Accordingly, we focused on the inter-relationships among well-established CV mental health risk factors, specifically childhood adversity, stress-related adult personality traits and psychiatric symptoms, and naturally occurring genetic polymorphisms. Materials and Methods: Here 100 college students completed the NEO Five Factor Model of personality in conjunction with measures of childhood adversity, psychiatric symptoms as well as genetic variables derived from assays of the serotonin transporter (5-HTTLPR) and the brain-derived neurotrophic factor (BDNF).

Results:

Single gene comparisons pointed to lower CV risk, as reflected in personality and psychiatric symptom measures for BDNF Met versus Val/Val carriers. In addition, polygenic comparisons revealed a significant BDNF x 5-HTTLPR interactional effect, suggesting that this particular allelic combination may moderate the phenotypic expression of key personality traits, namely neuroticism and extraversion, as well as psychiatric symptoms, all linked to cardiovascular health. In fact, the data showed across personality and symptom measures, evidence of stress-resistance, resilience and protection for carriers of the allelic pair, BDNF Met and 5-HTTLPR-S. Conclusions: The findings suggested the Met variant of the BDNF gene had a risk-reducing and health-promoting effect when paired with the short serotonin allele, arguably reversing the commonly reported 5-HTTLPR-S association with stress vulnerability.

Динамика и спектральная устойчивость солитоноподобных структур в мембранных трубках с жидкостью
Authors: Il'ichev Andrej Teimurazovich
Published: September 2020

В обзоре излагаются результаты об устойчивости уединенных волн возвышения в осесимметричных упругих мембранных трубках, заполненных жидкостью. Материал упругой трубки характеризуется упругим потенциалом (упругой энергией), нелинейно зависящим от главных деформаций и описывающим податливые упругие среды. В обзоре используется простая модель невязкой несжимаемой жидкости, которая тем не менее позволяет отследить основные закономерности динамики уединенных волн. К одной из таких закономерностей относится спектральная устойчивость (линейная устойчивость по форме) этих волн. Формулируются основные уравнения системы "осесимметричная трубка-идеальная жидкость", причем в уравнениях для жидкости производится осреднение по поперечному сечению трубки, т. е. рассматривается квазиодномерное течение с волнами, длина которых существенно превосходит радиус трубки. Изучение спектральной устойчивости относительно осесимметричных возмущений производится при помощи построения функции Эванса для линеаризованной вокруг решения типа уединенной волны системы основных уравнений. Функция Эванса зависит только от спектрального параметра $\eta$ и аналитична в правой комплексной полуплоскости $\Omega^+$, а ее нули в $\Omega^+$ совпадают с неустойчивыми собственными значениями. Рассматриваются задачи об устойчивости неподвижных уединенных волн в случае отсутствия жидкости внутри трубки (случай постоянного внутреннего давления), в том числе и для локальной неоднородности (утончения) стенки трубки, в случаях неподвижной жидкости, заполняющей трубку (случай нулевого среднего течения), и движущейся жидкости, а также задачи об устойчивости бегущих уединенных волн, распространяющихся вдоль трубки с ненулевой скоростью.

Indian dairy industry emerged as an important sector for income and employment generation, and is contributing as well in the country’s economy besides improving the health standards. The output from dairy sector has increased at more than 4.0 % per annum since 2010-11. The changing economic scenario an entrepreneur has to be very alert and should always keep an eye on the cost and returns of the scarce resources of an entrepreneur in order to keep himself profitable. Dairying in our country dominated by the small holders. Now the producers are scaling up their capacity by incorporating newer technology. One hundred and sixty milk pourer farmers were selected randomly using probability proportional to size (PPS) from the list of producers who were supplying milk to organized dairy (cooperative or private) purely and exclusively from eight village level milk chilling units of Lucknow and Hardoi district purposively selected from Lucknow region. Average variable cost varies from 88.72 small, 88.95 medium, and 92.38 large farmers and rest 11.28, 11.05 and 7.62 were the fixed cost for small medium and large category farmers respectively. The cost of milk production was higher for Rs 18.02, Rs 16.30 and Rs 15.85 per liter for small medium and large farmers respectively. The average milk selling price was found to be almost at par for small Rs 27.77, Rs. 27.31 and Rs. 27.11 for small, medium and large category farmers. Whereas, the average income generated by investing one rupee was found lowest for small Rs. 1.56 followed by medium Rs.1.71 and large Rs. 1.75 farmers respectively. However, the farmers have generated average annual income of Rs 70334.21, Rs. 128671.1 and Rs.230510.8 by small medium and large category farmers respectively.
To examine the magnitude and dimensions of agricultural diversification in western Uttar Pradesh
Authors: Paliwal M. K. , Govilla A. K. , Tyagi M. P.
Published: September 2020

The Present study was undertaken in Baghpat and Ghaziabad district of Western U. P. based on high and low productivity of major crops in the year 2006-07. Two blocks from each of these two districts were selected randomly for the study in total 240 respondents from Ghaziabad and Baghpat district each were interviewed. It was observed during the survey that sugarcane and wheat are the predominant cropping system in these two districts of western Uttar Pradesh. Marketing and cost factor are major socio-economic constants for diversification of forming system towards vegetables, fisheries, piggery, poultry etc. Diversification of agriculture through high value enterprises implies shifting from low value food/non food crops and allied activities to high value food/non food crops and allied enterprises in the agriculture. It means switching over from local to high yielding varieties with integration of high paying enterprises such as horticulture, aquaculture, apiculture, sericulture live stock, poultry etc.

A present study was carried out in villages of Shivpuri and Datia of Gwalior region of Madhya Pradesh from rural women to study the scenario in terms of cleanliness and hygiene and its associated aspects at the rural households prevailing in the rural areas. The study indicated that on an average (59%) of the rural women never carried food along with them to their work place in their morning which gave a long break for food intake. The rural women (69%) possessed kachcha houses followed by semi pakka (26.5%) houses. Most of the rural women (89%) done their cooking by Normal chulha which worked on firewood in the sampled villages in both the districts and almost none rural households found modern type of kitchen appliances in their houses like Mixer and grinder, Microwave. The rural women was witnessed both closed and open type of kitchen (48% and 52%) in the sampled villages in the region. The almost 88% and 89% rural women kept maintained cleanliness inside their houses, but having no proper ventilation(100% and 93%), disposal of water(92% and 78% ), disposal of garbage(88% and 72%), as well as cleanliness outside house surrounding(95% and 83%) in the sampled villages of Shivpuri and Datia district respectively. The water scarcity has been a major problem in these two districts. The hand pumps (63%) found the main source of drinking water in the region followed by well (37%) and 39% rural women brought drinking water from 101-200 meters distance followed by 37% from more than 200 meters only 24% rural women could arrange drinking water for their household consumption from nearby places.

An experiment was conducted at Ludhiana, during Kharif and Rabi season on loamy sand soil consisting of twelve treatment combination arranged in split plot design and replicated three times with three bed planting, viz., Fresh bed (FB), Permanent bed (PB) and Alternate bed (FB/PB) in main plot two crop residue management viz., residue incorporation/ mulching (R) and no incorporation / no mulching (R0) and two seed rate/ nitrogen level viz., 75 kg ha-1 (S100) and 93.75 kg ha-1 (S125) / 90 kg N ha-1 (N90) and 120 kg N ha-1 (N120) in sub plot. In soybean treatment, R recorded significantly higher grain (22.60 q ha-1) and straw (44.50 q ha-1) yield as compared to R0. FB/ PB recorded highest grain (22.60 q ha-1) and straw (43.90 q ha-1) yield followed by PB (21.40 q ha-1) and FB (21.20 q ha-1). S125 recorded higher grain (22.30 q ha-1) and straw (44.80 q ha-1) yield then S100. Highest gross return (Rs ha-1), Net return (Rs ha-1), and B:C ratio was also obtained under FB/PB, R and S125 treatment as compared to other treatment . In wheat treatment FB recorded highest grain (41.40 q ha-1) and straw (53.60 q ha-1) then FB/PB and PB. R treatment recorded higher grain (41.10 q ha-1) and straw (53.30 q ha-1) yield then R0. N120 treatment recorded higher grain (41.20 q ha-1) and straw (53.30 q ha-1) yield. Highest net return (Rs 29442.20 ha-1) and B:C ratio (2.05) was obtained under PB then FB and FB/PB. R0 treatment recorded higher net return (Rs 30873.86 ha-1) and B: C ratio (2.15) then R treatment. N120 treatment recorded higher net return (Rs 29402.56 ha-1) and B:C ratio (2.0) under water stress condition in dry areas.

A geomorphological instantaneous unit hydrograph (GIUH) model was developed for a watershed of Damodar valley corporation, Hazaribagh, using Nash (1959) and Itrube (1982) methods to compute peak discharge (qpeak) and time to peak (tpeak). The model was calibrated and validated for five storm events, i.e. June 24-25 (1992), October 12-13 (1993), November 2-3 (1993), June 28 (1994) and August 6 (1996) by comparing their ordinates with the ordinates of instantaneous unit hydrograph (IUH). The GIUH was tested with absolute prediction errors (APE) of the ordinate of peak discharge. On comparison, it was found that, most of the GIUH models overestimated the runoff at initial stage, while underestimated at the latter stage in comparison to the IUHs, which was mainly due to consideration of const ant value of Ф-index, for computation of effective rainfall. The absolute prediction errors (APE) were computed to be 5.97, 18.09, 23.32, 9.64 and 7.52% of the ordinates of peak discharge for the storm events of June 24-25 (1992), October 12-13 (1993), November 2-3 (1993), June 28 (1994) and August 6 (1996) respectively.

Published: September 2020

Small-grained cereal grasses are collectively called as ‘Millets’, being one of the oldest cultivated foods known to humans. There are two main groups of millets first group consist of major millets (sorghum and pearl millet) and second group has small millets this categorization is based on the grain size, this classification is also an indication of the area under cultivation of these crops, but both (major and small millets) have traditionally been the main components of the food basket of the poor people in India, especially in dry-land farming system in India and elsewhere.

Potato is a staple food crop in high hills and mountains and a major vegetable throughout the country and one of the most important cash generating crops in Nepal. With the efforts undertaken by research and extension sectors, its productivity has significantly increased in last twenty years. However, this is not sufficient for increasing population of the country. Considering its potentiality for income, employment, industrial products, export and processing, appropriate technologies are urgent.Soil fertility evaluation is the most basic decision making tool for the sustainable soil nutrient management. Soil fertility studies and mapping is an effective way to diagnose soil status and recommend as per the need of the nutrient to particular crop in the area. This research aims to assess and prepare soil nutrient map of potato super zone, Kavrepalanchowk in Nepal. The specific objectives of the research were to assess soil texture, pH and organic matter status and simultaneously prepare soil fertility map of the potato super zone. A total of 202 soil samples were collected and nutrients were analyzed using standard procedure in the soil laboratory. Composite soil samples were collected from 6 to 10 different spots of the area at 0-20 cm depth by using soil auger. The GPS location of each soil sampling point was noted. The soil sampling point of each zone was determined by studying various aspects (area, slope, colour, texture, etc.) of the study area. Based on the nutrient status, nutrient maps were prepared and presented. Soil fertility maps were prepared by observing the critical nutrients required for the specific crops and by giving those nutrients certain ranking based on the nutrients role for the crop. The soil of Potato super zone was mostly found to be silty loam, moderately acidic (pH 5.9), medium in organic matter content (2.67%) and total nitrogen (0.13%), high in available phosphorus content (56 kg/ha) and available potassium (356kg/ha). There is also sandy loam, loam and silty clay loam types of soil in the area. Soil fertility maps were prepared by setting criteria based on nutrient status that were tested in the laboratory and on the basis of nutrients that are critical for each crops of the super zones. Vegetable super zone soil was found having medium (50%) and high (30%) fertility status. Based on the soil analysis report, it could be concluded that the soils of potato super zone is fair enough for cultivating potato crop at the moment.

The present investigation was carried out to study the efficacy of different novel insecticides and bio-pesticides against stem borer Scirpophaga incertulus (Walker) during kharif 2015-16 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Efficacy of newer insecticides (fipronil 5 SC, cartap hydrochloride 50SP,chlorpyriphos 20 EC, imidacloprid), one biopesticide (Neemarin 1500 ppm) and one bio-control agent (Trichogramma japonicum) were evaluated against yellow stem borer Scirpophaga incertulas (Walk.) in Basmati rice. The stem borer recorded as dead heart ear heads ranged from 4.85 to 10.55 per cent and white ear head showed that it was recorded on 38th standard weak. All the treatments were found significantly effective in reducing the infestation of stem borer and increasing the yield compared with control. Application of fipronil 5 SC was the most effective treatment in reducing the stem borer infestation at all observational interval resulting highest grain yield The results of paddy yield depicted in table 3, showed that the plots treated with fipronil 0.3 GR @ 25 kg/ha gave the highest yield (45.56 q/ha).
