Published: February 2023

Host parasitoid interactions in insects offer some innovative opportunities for the development of successful biocontrol programmes in field crops. Aenasius arizonensis (Girault) is a species specific, solitary endoparasitic wasp of the cotton mealybug, Phenacoccus solenopsis Tinsley and a potential insect control tool. Effects of temperature on different biological traits of A. arizonensis were studied at different constant temperatures i.e., 20±2 ̊C, 25±2 ̊C, 30±2 ̊C and 35±2 ̊C with a relative humidity of 65±5%. Host insects/mealybugs were reared on sprouted potatoes or pumpkins. Total developmental period of the parasitoid at different constant temperatures was recorded with the daily parasitization rate (number of host insects parasitized). At respective temperatures, oviposition and post-oviposition periods were also observed along with the longevity of the male and female wasps. Sex ratio (male: female), reproductive rate, intrinsic rate of increase, and finite rate of increase were also determined at all temperatures. The most favorable temperature for the development and reproduction of the parasitoid was observed as 30±1 oC. The information obtained from this preliminary study will be helpful in establishing a mass rearing programme for the parasitoid leading toward sustainable insect pest management of cotton mealybugs in economically important crops.

FLOW AND PRESSURE CONTROL OF A FIELD SPRAYER USING PID CONTROLLER
Authors: Karadol H
Published: February 2023

Recently, different methods have been developed in order to increase the application efficiency of agricultural sprayer systems. The dynamic control of flow and / or pressure is performed by the proportional control of pumps or valves. The aim of the current study was to minimize the application rate error of field sprayers using the pump motor variable speed drive (VSD) of a centrifugal pump system. The flow rate and pressure control of the pump system was achieved using a Proportional Integral Derivative (PID) controller. During the tests, in the first stage, the flow rate-speed ratio was kept at a constant value to apply a constant application rate with varying ground speeds. In the second stage, the control of the system pressure was accomplished using the manually applied disturbing effects on the system. In the final stage, the flow rate of a spray nozzle was controlled by Pulse Width Modulation (PWM) depending on the speed at different constant pressure values. In flow control test, absulute percentage error of application rate in only six out of 150 measurements were higher than 10% which is acceptable application rate error at varying ground speeds from 6 to 10 km h-1. In pressure control tests, it was observed that the controller moved the system pressure back to the set value within 2-3 seconds after a disturbance applied. The system was able to control the nozzle flow rates between 50% and 100% by changing the duty cycle of the signal applied to the solenoid valve at the nozzle inlet during the PWM spray tests. Further investigation is required to test the observation in the current experiment on field sprayers to improve the efficiency of constant and variable rate or PWM applications.

Published: February 2023

Sweet potato residue (SPR), a byproduct generated during starch extraction from sweet potato, is usually treated as an agro-waste, resulting in lower economic benefits and serious environmental pollution. To promote resource recycling, SPR was used as a starting material to prepare a microbiological protein feed (MPF) by co-cultivating Saccharomyces cerevisiae and Candida utilis. The cultivation conditions were investigated, and the optimum conditions were determined as follows: inoculation amount of S. cerevisiae, 5%; inoculation amount of C. utilis, 5%; water content of SPR, 75%; urea, 1%; cellulase, 0.5%; and isoamylase, 0.5%, at a culture temperature of 32°C. Under these conditions, true protein content in fermented SPR was enhanced to 18.08%, which was 6.34 times that of the original SPR. Amino acid composition and the essential amino acid index (EAAI) indicated the high nutritive value of MPF to cattle, rabbits, and lambs. This simple method provides a strategy for recycling and reusing agricultural residues in an economical and environment-friendly manner.
Key words: Sweet potato starch residue, Protein Feed, Saccharomyces cerevisiae, Candida utilis, Resource regeneration.

Published: February 2023

Pinellia ternata (Thunb.) Briet. is a well-known traditional Chinese herbal medicine that has many beneficial effects such as anti-tumor, anti-fertility, blood fat-reducing, and liver-protective. The comprehensive utilization value of P. ternata is high and the development prospect is broad. However, low tuber production resulting from “sprout tumble” (ST) due to high temperature and light intensity has largely reduced its use. Therefore, it is necessary to explore the functional gene responses to high temperature and light. Real-time quantitative PCR (RT-qPCR) is commonly used for accurately gene expression detection during gene function exploration. However, because the RT-qPCR results may vary depending on the conditions and environment, an internal reference gene (IRG) is needed to normalize the RT-qPCR data. Analyzing IRGs in P. ternata can help with subsequent functional characterization and verification of the genes regulating P. ternata growth. In this study, we screened 8 suitable IRGs, and determined the most suitable IRGs using the Ct value, GeNorm, NormFinder, and BestKeeper under shade and high-temperature conditions, and in different tissues. The results showed that 18S was a suitable IRG for P. ternata studies. This discovery has laid the foundation for further research on P. ternata, and is also beneficial for the exploration of more IRGs in medicinal plants.

TIME-BASED CHANGES IN ESSENTIAL OIL CONTENTS AND COMPONENTS OF ENGLISH LAVENDER (Lavandula angustifolia MILL.) AFTER FOLIAR APPLICATION OF GIBBERELLIC ACID (GA3)
Authors: Izmirli A , Yildirim M.U.
Published: February 2023

Lavender (Lavandula angustifolia Mill. family Lamiaceae) is a perennial and highly drought tolerant plant species. It grows well on calcareous slopes, and produces a fragrant essential oil. The aim of study was to evaluate foliar application of gibberellic acid (GA3) and delaying harvesting for different durations on essential oil and components of English lavender after foliar treatment with 0, 200, 400 and 600 mg l-1 gibberellic acid (GA3). Clevenger apparatus-based water-vapor distillation method was used to determine essential oil and its components by GC-MS. The experiment was established in split plots in randomized complete block design with two factors and 3 replications. The main plots were formed at harvest time and the sub-plots were created by GA3 applications. Statistical analyzes were made using MSTAT-C package program. When the GA3 doses and harvest times interaction were evaluated together, the average essential oil yield of the harvested lavender flowers ranged 6.20 to 8.20 % showing the prominent influence of the concentration of GA3 and delay in harvesting (in hours) on concentrartration of alkaloids. More than 50 components were identified, the most important among these was 1.8-cineole, linalool, camphor, borneol, lavandulol, and terpinene-4-ol. The amount of linalool, which improves the quality of the essential oil ranged 34.49-38.75%. The minimum and the maximum essential oil values were noted from the flowers harvested after 30 hours (control treatments), and 54 hours from 400 mg l-1 GA3 treated plants in the same order. However, essential oil contents showed a slight decrease at higher GA3 treatments and prolonging duration of harvest after respective GA3 treatments. GA3 treatments enhanced the quantity of essential oil substantially, and the optimal dose was determined as 400 mg l-1 GA3 on samples harvested after 54 hours following application. The results further showed that the quantities of essential oil's primary components varied according to harvest time.

Design and Fabrication of a Cost Effective Lab Rock Cutting and Polishing Machine
Authors: Adebayo Fatuase Fiyinfoluwa
Published: February 2023

To meet some testing specifications, rock samples taken from an in-situ rock mass must be cored and polished into standard sizes. The sample length, smoothness, diameter, and thickness are examples of such specifications. All of these specifications have an impact on the test result and the achievement of the test goal. As a result, rock polishing and cutting operations are required in the laboratory to prepare and work on various types of samples. Most of the time, these machines are built differently, which is efficient but costly, rigorous, and takes volume and shape in the laboratory. A specimen-cutting and polishing machine was designed and built to help researchers obtain mineral/rock specimens for strength testing. This machine is made up of an electric motor, a diamond cutting disc, and an electric pump for water cooling. To convert electrical energy into mechanical energy, a 1.15KW electric motor was used. A central electrical distribution grid provides alternating current to an electrical motor. The designed machine used a 380V, 50Hz electric motor with a rotating speed of 1.83 m/min and a torque of 109.38 KN. The cutting machine was designed and built to cut and polish different materials in order to obtain specimens for strength tests and structure inspection.

Is there a place for children in the making of public policy? Insights from the research evidence
Authors: Stenvall Elina , Kurki Marjo , Virtanen Petri
Published: February 2023

Article 12 of the UN Convention on the Rights of the Child stipulates that children have a right to express their views with this article being one of the most frequently cited principles in the convention. This scoping review summarises the existing research evidence on how children participate in the making of public policy. This paper concludes that a plethora of practical guidelines and gray literature are available addressing children as policy-making partners, but the empirical research around the subject is very rare. Children’s participation should be planned prior to any planned public policy reforms – and to be supported by appropriate academic research integrated into the different stages of the policymaking processes. If policymakers are willing to develop mechanisms for children’s participation in the policy cycle, children’s role and agency will be clarified. It seems that there is a need for new sensemaking in terms of how adults treat the value of children´s participation and how to include children in the policymaking process around the subjects that matter to them. Participatory practices should be co-created with children, not for them.

Agricultural Grid Connected Photovoltaic System Design and Simulation in Egypt by using PVSYST Software
Authors: Farghally Hanaa M. , Sweelem Emad A. , El-Sebah Mohamed I. Abu , Syam Fathy A.
Published: February 2023

Agricultural Photovoltaic Systems are a key technology to achieve sustainable development goals by reducing competition between land for food and electricity. In addition, Agricultural Photovoltaic Systems are at the heart of the link between power generation, crop production and irrigation water conservation. The main ecophysiological constraint on crop production under photovoltaics is the reduction of light. It is difficult to recommend shade tolerance for some plant varieties due to insufficient information on shading conditions for most plants. The use of shading panels (photovoltaic panels) requires more crop-specific research to determine the optimal percentage of panels and their placement that will not reduce agricultural yields. Crop yield variation versus field shading and availability to maximize the system require extensive research. This study aims to develop a standard procedure for designing an agricultural grid-connected photovoltaic power generation system for solar power generation in an agricultural area in Bahteem, Egypt. The technical and annual performance of the grid-connected PV system was simulated using PV Syst software. The paper started with a pre-feasibility study of a grid-connected photovoltaic system using PV Syst. Software with an extensive database of meteorological data, including global daily horizontal solar irradiance, and a database of various renewable energy system components from different manufacturers. In this work, a comprehensive literature review of agricultural solar photovoltaic systems is conducted, with a particular focus on grid-connected systems, followed by a design procedure for grid-connected solar photovoltaic systems. The planned photovoltaic system will generate a total of 400 KWp of electricity. This generated electricity can drive down electricity prices by exporting excess electricity to the national grid. In addition, solar power systems are fuel-efficient and have a low environmental impact.
Visual and Quantitative Analyses of Virus Genomic Sequences using a Metric-based Algorithm
Authors: Belinsky Alexandra , Kouzaev Guennadi A.
Published: February 2023

This work aims to study the virus RNAs using a novel accelerated algorithm to explore any-length repetitive genomic fragments in sequences using Hamming distance between the binary-expressed characters of an RNA and a query pattern. Primary attention is paid to the building and analyzing 1-D distributions (walks) of atg-patterns - codon-starting triplets in genomes. These triplets compose a distributed set called a word scheme of RNA. A complete genome map is built by plotting the mentioned atg-walks, trajectories of separate (a-, c-, g-, and t-symbols) nucleotides, and the lines designating the genomic words. The said map can be additionally equipped by gene’s designations making this tool pertinent for multi-scale genomic analyses. The visual examination of atg-walks is followed by calculating statistical parameters of genomic sequences, including estimating walk- geometry deviation of RNAs and fractal properties of word-length distributions. This approach is applied to the SARS CoV-2, MERS CoV, Dengue, and Ebola viruses, whose complete genomic sequences are taken from GenBank and GISAID. The relative stability of these walks for SARS CoV-2 and MERS CoV viruses was found, unlike the Dengue and Ebola distributions that showed an increased deviation of their geometrical and fractal characteristics. The developed approach can be useful in further studying mutations of viruses and building their phylogenic trees.

India’s Transition towards Green Economy
Authors: Nazeerudin Nazeerudin
Published: February 2023

The agricultural sector’s contribution to India’s Gross Domestic Product (GDP) has dropped from 17.4% in 2006-07 to 14.2% in 2010-11i, while the manufacturing sector has underperformed, accounting for only 20% of GDP, due to high interest rates, infrastructure bottlenecks, slow decision-making by the government, and weak domestic demand Furthermore, the service sector, which accounts for nearly 65% of GDP, has also been losing its momentum due to segments like the banking and real estate facing demand and investment constraints. Furthermore, the environment has suffered gravely with the economic progress as from 1990 to 2008, India’s GDP per capita rose by an impressive 120% leading to the natural capital to decline by 31 % in the same period. Adding to that, currently India is operating on almost twice its bio-capacity; indicating that the population’s demand from the ecosystem exceeds the capacity of that ecosystem to regenerate the resources.  To ensure that inter-linkages between the economic, societal, and environmental aspects of development are overarching, India needs vital transitions. A green economy strengthens pro-poor economic growth by building up natural capital and secures livelihood options of the poorIn the light of the above Context, this paper attempts to understand the key sectors for intervention in India and have emerged as the main players in undertaking green initiatives. These sectors have contributed to economic growth of the nation while simultaneously causing detrimental effects on the environment. Section 2 of the paper makes an analysis of the six sectors that have the potential of contributing towards achieving the balance along the three pillars of sustainability. Section 3 further analyses the dominant barriers faced by some of the initiatives and how they can possibly be overcome.   Finally it the    foundation for further research and understanding the viable agents of changes for bringing about this transition.

Published: February 2023

The aim of the study was to identify and confirm the factors for two generations namely GEN Z and GEN Y.2 which they perceive to be important for career choice. Data was collected from 466 respondents of GEN Z and 446 respondents of GEN Y.2 which were used to examine psychometric properties of the identified factors. PCA was used to initially determine the factors for both the generations using SPSS.21. The identified factors were confirmed using PLS 3. For GEN Z Freedom of choice, parental achievements, parental aspirations, parental educational qualifications & awareness and lastly parental support were the confirmed factors. For GEN Y.2 the confirmed factors were parental aspirations, parental support, parental education & awareness, parental achievement & motivation and finally parental occupation. Confirmed factors for both the generations revealed acceptable internal reliability, and convergent validity. In addition to this the study also highlights the key differences among the identified factors for the two generations. The present study reveals that the GEN Z gave more importance to freedom of choice and GEN Y.2 gave more importance to parental aspirations. Thus, the present study provides insights for parents to understand how their role is changing when it comes to managing the career choice of their adolescents. The results also highlights that parents need to be more thoughtful, alert and adaptive with changing times while providing interventions to their adolescents when they are making a career choice.
INTERTEXTUAL PARODY IN E. L. DOCTOROW’S RAGTIME AND LOON LAKE
Authors: Rigley F. Julian Xercies
Published: February 2023

Contemporary metafictions are characterized by several dominant features that interrogate the established norms and thus make the readers think over the unquestioned realities. E. L. Doctorow, an American postmodern novelist uses parody as a literary tool to question the rigid framework of American literary society. By incorporating intertextuality, Doctorow creates skepticism over the autonomous status of literary texts. Being a significant feature of postmodernism, intertextuality unravels the fact that each text is an inevitable composition of several other texts. This paper demonstrates how efficiently Doctorow incorporates intertextual parody in Ragtime and Loon Lake.

Published: February 2023

A implementação de dois estaleiros de grande porte no município de Rio Grande, apoiados pela política de mobilização da indústria naval no país, trouxe diversas transformações para o sul do Rio Grande do Sul. Com a intenção de avançar na análise dos efeitos gerados pela política, este artigo tem como objetivo mensurar os principais efeitos socioeconômicos gerados pelos investimentos no setor naval no município de Rio Grande. Para tanto, utilizou-se o método de controle sintético com base em um painel de dados municipais do Rio Grande do Sul no período de 1997 a 2015. Os resultados apontaram que os investimentos do segmento naval no município promoveram a ampliação da geração de empregos formais, principalmente nos setores de construção civil e indústria de transformação, o produto interno bruto (PIB) e, por consequência, a arrecadação de impostos, como Imposto Sobre Serviços (ISS) e Imposto Sobre A Propriedade de Veículos Automotores (IPVA). Além disso, houve também um aumento do número de internações hospitalares e também uma redução no número de matrículas no ensino médio no município. Esses resultados revelam que, no período de pujança dos investimentos no setor naval, houve melhoria na condição de renda da população, porém, também, ocorreu uma sobrecarga na infraestrutura municipal, que se traduziu principalmente no âmbito da saúde pública.
Método para identificar concorrência ruinosa no setor de transporte rodoviário interestadual de passageiros
Authors: Ribeiro Hugo Alves Silva , Rocha Carlos Henrique
Published: February 2023

O serviço de transporte rodoviário interestadual de passageiros no Brasil é de grande importância para o seu desenvolvimento econômico e social. Trata-se de um setor tradicionalmente oligopolista, cujas políticas públicas restringiam a competição no mercado. Isso vem mudando desde 2014, quando a outorga desse serviço passou de permissão para autorização, pressupondo ambiente mais competitivo e ausência de controle tarifário. No entanto, prevendo o aumento descontrolado na quantidade de empresas de ônibus, operando em um determinado trecho, o poder público regulamentou que, quando for identificada concorrência ruinosa no mercado, seria possível limitar o número de operadores nessa rota. Isso gerou uma lacuna normativa, tendo em vista que o Estado não estabeleceu critérios capazes de definir concorrência ruinosa. Este artigo tem a finalidade de propor um método capaz de identificar essa situação por meio da economia industrial, envolvendo em particular os conceitos de custos e de regulação econômica. Ao final, a técnica é testada em mercados reais e se apresentou satisfatória para a finalidade proposta.

Este artigo avalia o impacto da gestão governamental do estado do Ceará nos indicadores educacionais, de cunho quantitativo e qualitativo, referentes ao ensino médio, no período de 2007 a 2014. Para tanto, utilizou-se o método de controle sintético. Uma análise descritiva mostrou uma evolução contínua do estado do Ceará, permanecendo acima da média da região Nordeste. O estado, a partir de 2009, ultrapassa a média nacional, permanecendo acima até o fim do período considerado. Na abordagem qualitativa, destaca-se o rápido crescimento entre 2011 e 2014, de modo que o Ceará, anteriormente abaixo, acompanha o desempenho nacional. Em suma, a partir dos resultados, conclui-se que a intervenção analisada, a gestão do governo do estado do Ceará de 2007 a 2014, apresentou bom rendimento na educação, tanto quantitativamente quanto qualitativamente.

A seca é um fenômeno climático predominante no semiárido brasileiro e os pequenos agricultores enfrentam dificuldades na produção devido à escassez hídrica. Nesse sentido, o Programa Uma Terra e Duas Águas (P1+2), que faz parte do Programa de Formação e Mobilização Social para a Convivência com o Semiárido, surge com o intuito de ampliar a oferta de água para a produção agrícola no semiárido, por meio da captação de água da chuva em cisternas. Para verificar se esse programa está correspondendo ao que foi planejado, este estudo se propõe a avaliar o impacto do P1+2 no semiárido cearense, mais especificamente no município de Iguatu, quanto a seu efeito sob a renda, o emprego e a sustentabilidade na produção dos pequenos agricultores da região, utilizando-se do propensity score matching. Os resultados encontrados indicam que o programa está promovendo melhorias nas rendas agrícola e agropecuária do público beneficiado. No que diz respeito aos empregos e à sustentabilidade da produção, não foi possível obter resultados estatisticamente significantes de average treatment effect on the treated (ATT). Com relação à comparação da média do índice de sustentabilidade na produção entre os beneficiários e não beneficiários, há diferença significativa favorável ao grupo de beneficiários.
O Impacto da posse da terra do agricultor familiar sobre o acesso ao crédito rural

Published: February 2023

O crédito rural abrange recursos destinados a custeio, investimento e comercialização, sendo o principal instrumento da política agrícola brasileira. Entretanto, a ausência de direitos de propriedade sobre a terra é um fator controverso que gera, por sua vez, restrição de crédito, dado que esse ativo é utilizado como garantia. Tal restrição é marcadamente severa particularmente ao grupo de pequenos agricultores que, no Brasil, possuem o Programa Nacional de Fortalecimento da Agricultura Familiar (Pronaf) como única política pública a eles destinada. Assim, por intermédio dos microdados da Pesquisa Nacional por Amostra de Domicílios (PNAD) 2014, este estudo buscou avaliar o impacto da posse da terra das denominadas “pessoas potencialmente classificadas como agricultor familiar” (PPCAF) sobre o crédito rural no Brasil. Para tanto, fez-se uso dos métodos de balanceamento por entropia e propensity score matching e analisou-se então a sensibilidade de modo a averiguar a robustez dos resultados em face das variáveis omitidas. De acordo com os resultados obtidos, a posse da terra está positivamente relacionada ao crédito rural, principalmente na região Sudeste. Em contraste, os resultados para as regiões Sul e Centro-Oeste não se revelaram estatisticamente significantes.

Este artigo aborda a importância de se fazer uma análise quantitativa, utilizando-se dados históricos de projetos reais, a respeito dos riscos inerentes a uma parceria público-privada (PPP) do tipo DBFMO (design, build, finance, maintain, operate) para o setor hidroviário, abordando o caso específico da hidrovia do Tocantins. A análise é guiada pelas etapas do gerenciamento de risco descritas pelo Project Management Institute (PMI), passando pela identificação e análise qualitativa de riscos e, posteriormente, a análise quantitativa. Aplicando-se a simulação de Monte Carlo com dados referenciais de contratos anteriores, foi obtido um valor monetário esperado (VME) da implantação da hidrovia, levando em consideração os riscos altos para esse empreendimento, em suas diversas fases de implantação.
Solar Flare Ribbon Fronts. I. Constraining Flare Energy Deposition with IRIS Spectroscopy

Spectral lines formed at lower atmospheric layers show peculiar profiles at the “leading edge” of ribbons during solar flares. In particular, increased absorption of the BBSO/GST He i
λ10830 line, as well as broad and centrally reversed profiles in the spectra of the Mg ii and C ii lines observed by the IRIS satellite, has been reported. In this work, we aim to understand the physical origin of such peculiar IRIS profiles, which seem to be common of many, if not all, flares. To achieve this, we quantify the spectral properties of the IRIS Mg ii profiles at the ribbon leading edge during four large flares and perform a detailed comparison with a grid of radiative hydrodynamic models using the RADYN+FP code. We also studied their transition region (TR) counterparts, finding that these ribbon front locations are regions where TR emission and chromospheric evaporation are considerably weaker compared to other parts of the ribbons. Based on our comparison between the IRIS observations and modeling, our interpretation is that there are different heating regimes at play in the leading edge and the main bright part of the ribbons. More specifically, we suggest that bombardment of the chromosphere by more gradual and modest nonthermal electron energy fluxes can qualitatively explain the IRIS observations at the ribbon leading front, while stronger and more impulsive energy fluxes are required to drive chromospheric evaporation and more intense TR emission in the bright ribbon. Our results provide a possible physical origin for the peculiar behavior of the IRIS chromospheric lines in the ribbon leading edge and new constraints for the flare models.
