The development of integrated business structures of Ukraine on innovative and investment basis

The article considers the directions of the development of integrated business structures based on innovation and investment in the agro-industrial complex of Ukraine. The paradigm of the development and functioning of integrated business structures of the agro-industrial complex of Ukraine, which intensify the innovative-investment process and network interaction of public-private partnership in a competitive environment, has been implemented. It is proved that the impact of public-private partnership on innovative-investment development and the creation of real value of business structures of the agro-industrial complex should be considered for different periods associated with the appropriate levels of evaluation of their effective cost-oriented platform. The efficiency of the functionality of business structures of the agro-industrial complex, which is characterized from the standpoint of time, level and integrated approaches, is determined. The temporal approach provides the allo-cation of three periods – short-term, medium-term and long-term, for each of which specific criteria for assessing the effectiveness of functionality is determined. A block diagram of qualitative criteria for evaluating the effectiveness of business structures in the introduction of innovations and investments in agriculture from the standpoint of the interests of a group of stakeholders in public-private partnership on a time basis is presented. The comparative characteristics of innovative-investment activity of business structures in high- and low-tech branches of the agro-industrial complex are determined. A model of integrated interaction of network interaction between business structures of the agro-industrial complex, institutes of agricultural development and stakeholders in public-private partnership has been developed. The institutional model of subsystems of the functional mechanism of harmonization of interests of business structures of agro-industrial complex and the state is offered. It is proved that the harmonious state regulation of investment activities of large agricultural producers (agricultural holdings) should be based on administrative, legal, organizational and economic methods and ensure compliance with norms and rules in the investment sphere at the level of relevant structural and functional institutions.
LAND USE/LAND COVER CHANGES ANALYSIS IN SUDANO GUINEAN REGION OF BENIN

Deforestation processes driven by anthropogenic activities lead to the loss of biodiversity and the alteration of ecological systems. In this paper, we examined the land use / land cover change trends from 2000 to 2020 in the Sudano-Guinean region of Benin, and analysed the driving factors of those changes. The adopted method is based on the diachronic analysis of the land cover through the use of remote sensing data specifically, Landsat satellite images of 2000 and 2020. The results showed that natural forest vegetation and Savannah strongly decreased, whereas farmland and the built-up area increased. Indeed, forest land lost 3.22%, 2.01%, and 1.57%, in Bante, Glazoué, and Ouèssè, respectively. The intensification of human activities was identified as the proximate driver while population growth, a growing demand for agricultural and forest products coupled with improved infrastructure were identified as the underlying drivers of deforestation. To achieve sustainable management goal for forest resources in Benin, the introduction of alternative sources of energy, sustainable farming practices, diversification of income sources, the promotion of community participation, should be implemented.
Extreme Temperature Events Can Mitigate COVID-19 Morbidity in Warm Arid Environments: A Conclusion from Late Spring 2020 Heatwave in Egypt

The COVID-19 pandemic disease affects us all and get the world into an enormous crisis. Temperature is an important factor in infectivity reduction of viral disease. The current study screens the probable association between the extreme temperature events and COVID-19 outbreak. The most recent heatwave that hit Egypt in May 2020 selected as a case study. We studied the daily progression and current situation of COVID-19 morbidity in Egypt. The concurrent heatwave was identified and synoptically explained in deep. Considering the incubation-induced lag time between heatwave intensities and COVID-19 confirmed cases, visual interpretation of line graphs discovered an interesting identical connection between the real-time thermal intensities and the 14-day retreated infected cases during the heatwave days. The 5-day heatwave with thermal intensities 6.1–7.8 °C led to a 5-day fall in COVID-19 morbidity. The thermal intensity peak of the heatwave caused the greatest decline in COVID-19 confirmed cases by about onethird. The 2nd order polynomial regression model for the relationship suggested that heatwave intensity of 5.5 °C is the critical thermal threshold at which COVID-19 morbidity begins to be reduced, and 10.7 °C as a threshold of COVID-19 outbreak pause. It is concluded that heatwave of late spring can effectively restrict COVID-19 pandemic outbreak in warm arid environments like Egypt. COVID-19 is also highly expected to be restricted as the temperatures increase with the advance of summer season. It is recommended that lag time resulted from the virus incubation period must be considered in COVID-19 mortality and morbidity researches.
RELATIVE SUSCEPTIBILITY OF SOME SOYBEAN VARIETIES TO THE MAIN PIERCING- SUCKING INSECTS

Pest resistant and tolerant crop varieties offer a major mean of pest control as it could be incorporated into integrated pest management programs to minimize the serious problems of insecticides. The current work was carried out at Sakha Agricultural Research Station Farm to evaluate the relative susceptibility of six soybean varieties (Crawford, Giza 21, Giza 22, Giza 111, H 30 and H 32) to infestation with the main piercing-sucking insects (whitefly, Bemisia tabaci Genn.; aphids, Aphis spp.; jassids, Empoasca spp. and green stink bug, Nezara viridula L.) during two soybean growing seasons;2009 and 2010. Data indicated that whitefly population was higher in the first season than in the second one on all the evaluated varieties, while the reverse was found for the other insects. Based on the mean number of the two successive seasons, Giza 111 significantly received the highest number of whitefly and jassids, followed by Giza 22, while Crawford and H 30 had the lowest whitefly and jassids density, respectively. Also, H 30 and Giza 111 significantly had higher number of aphids among the evaluated varieties. As for the green stink bug, the highest population was found on Giza 22, Crawford and Giza 111, while the lowest one was counted on Giza 21 and H 32 . In respect to susceptibility degree, Giza 111, Giza 22 and H 32 appeared susceptible to whitefly and jassids, while Crawford and H 30 appeared moderately resistant to whitefly and jassids, respectively. Giza 111 and H 30 appeared susceptible to aphids, while the other varieties showed low resistance. Also, Giza22, Crawford and Giza111 appeared susceptible to the green bug, while Giza21 and H32 appeared as moderately resistant. Generally, it can be concluded that Giza111 was the highest infested variety with all the tested insects. On the other hand, Crawford was the least infested variety with the whitefly and aphids, while H30 was the least infested with jassids and the green stink bug.
Market Participation of Smallholder Farmers and Food Crop Productivity: Evidence from Burkina Faso

Subsistence farming is frequently viewed as a low yielding and inefficient to ensure sustainable food security in sub-Sahara Africa. Commercial agriculture induces profit maximization and promotes on-farm investment. However, for most farmers in Burkina Faso, home consumption is the main objective of the agricultural production activities. Using survey data collected over 1178 farm households, this paper analyses the effects of participation of smallholder farmers in the output market on input use and food crop productivity in Burkina Faso. We estimate a Tobit model of the relationship between market participation (measured by the proportion of crop sold) and fertilizer use. The results show that an increase in level of sale leads to an increase in the level of fertilizer adoption. We also estimate a model of production using the instrumental variable regression approach to correct for the endogeneity of the crop commercialization index. The findings indicate that agricultural commercialization has a positive and significant effect on food crop productivity. This means that higher integration of farmers to markets increases their incentives to adopt new technologies which results in yield growth. Therefore, the findings confirm the need for promoting market participation of smallholders to induce technological change and productivity growth of agriculture in Africa.
Crystal chemistry of the 1M mica polytype: The octahedral sheet

Abstract This work provides a crystal-chemical description of the trioctahedral sheet in 1M mica polytypes of C2/m symmetry. Some octahedral parameters were found to be related strictly to octahedral chemical composition, whereas others were related to the overall layer chemistry. As a general rule, the M1 site is more affected by octahedral chemical composition than the M2 site, and octahedral distortions are more affected than octahedral size. This behavior is attributed to the constraints related to edge-sharing octahedra and octahedral-tetrahedral coupling, which involves the sharing of the apical tetrahedral oxygen atom between the tetrahedron and octahedron. A more quantitative explanation was sought by considering expressions that relate octahedral parameters as a function of atomic coordinates and unit-cell parameters. This procedure identified those parameters affected by local distortions and those that are a function of a more global effect and whose variation greatly affects the layer. Local distortions are obviously more likely a result of local chemical composition. The size and distortion of the octahedral sheet seem to be independent for the database of samples considered. The a angle was found to be a complex parameter required to: (1) fit tetrahedral and octahedral lateral dimensions; (2) fit tetrahedral topology to its local chemical composition, and (3) fit the interlayer cation electrostatic interactions.
Partial Strength Beam-to-column Connection of Cold-formed Single Channel Section: Numerical and Experimental Study

A full understanding of complex structural behaviour can be developed perfectly by using the combination of experimental and numerical approach. Although the basic method to determine the moment-rotation responses of the beam-to-column CFS joints has recently established from the fullscale testing, practising the finite element modelling (FEM) nowadays could explore in-depth on the number of variables and potential failure modes. In this paper, three-dimensional (3-D) model to simulate the actual behaviour of the beam-to-column CFS joints has been proposed by using multipurpose finite element package ABAQUS version 6.14 in order to validate analysis data against the experimental works. The approach of nonlinear material characteristics, contact and sliding between different components and adopting C3D8R solid elements are proposed in this model. A total of three (3) beam-to-column CFS connections consisting of three different types of beam depths were tested in isolation in order to observe the structural behaviour based on its strength and stiffness. Comparisons between experimental and FE analysis results in term of ultimate moment capacity have shown a good correlation with strength ratios ranging from 1.12 to 1.17. Therefore, it is possible to develop a realistic model for future parametric studies such as type and configurations of the connections.
Effect of Implementation Factors on Monitoring & Evaluation Results Utilization: Evidence from the Malaria Control Programs in Mukono District, Central Uganda

Empirical studies globally have revealed that utilization of findings from the Monitoring and Evaluation Function have been seen to be critical in projects especially in contributing to the success of interventions in communities. Unfortunately, implementation factors are advanced as limiting such utilization but remain less studied in Uganda. This study was thus set out to establish the effects of Implementation Factors on the utilization of Monitoring & Evaluation findings from the Malaria Control Programs implemented in Mukono District, Central Uganda. The study adopted a cross-sectional research design in which data was collected from a total of 120 randomly selected employees who were part of Malaria Control Programs implementation and a Multiple Regression Model fitted in SPSS Version 20.0, Results showed insignificant effects of evaluation quality, capacity and communication but positive significant effect of timeliness on the utilization of Monitoring and Evaluation Findings. It was concluded that on average, Monitoring and Evaluation results were rarely utilized in the implementation of the Malaria Control Programs among the implementing organizations (Mean = 2.34, S.D = 0.56). The study henceforth recommended that management staff of the organizations implementing programs should design and institute mechanisms which ensure timely collection, analysis and reporting of the Monitoring & Evaluation results if utilization levels are to be enhanced.
Impact of Drip Fertigation on Leaf Nutrient Status and Yield Attributes in Chilli ( Capsicum annuum L.) Hybrid CCH1

A field experiment to study the soil, plant nutrient status and yield of hybrid chilli ( Capsicum annuum L.) CCH1 as influenced by fertigation of N and K fertilizers was carried out during 2010-12. The experiment was laid out in Randomized Block Design with three replications and the treatments included were three levels (125, 100 and 75 % recommended dose) each of water soluble and straight fertilizers. The soil nutrient parameters viz . , available soil nitrogen, phosphorus, potassium content and plant nutrient parameters viz . , leaf nitrogen, phosphorus and potassium were recorded. The yield parameters like number of fruits per plant, fruit girth, and fruit weight, green fruit yield per plant and per plot were also recorded. The study revealed that the soil and plant nutrient contents in general increased up to 120 days and then declined. Among the several treatments, NPK @ 100 per cent recommended dose of water soluble fertilizers along with liquid biofertilizers registered the highest value for the soil, plant nutrient content and yield parameters.
A comparative study of anthropogenic CH4 emissions over China based on the ensembles of bottom-up inventories

Abstract. Atmospheric methane (CH4) is a potent greenhouse gas that is strongly influenced by several human activities. China, as one of the major agricultural and energy production countries, contributes considerably to the global anthropogenic CH4 emissions by rice cultivation, ruminant feeding, and coal production. Understanding the characteristics of China's CH4 emissions is necessary for interpreting source contributions and for further climate change mitigation. However, the scarcity of data from some sources or years and spatially explicit information pose great challenges to completing an analysis of CH4 emissions. This study provides a comprehensive comparison of China's anthropogenic CH4 emissions by synthesizing the most current and publicly available datasets (13 inventories). The results show that anthropogenic CH4 emissions differ widely among inventories, with values ranging from 44.4–57.5 Tg CH4 yr−1 in 2010. The discrepancy primarily resulted from the energy sector (27.3 %–60.0 % of total emissions), followed by the agricultural (26.9 %–50.8 %) and waste treatment (8.1 %–21.2 %) sectors. Temporally, emissions among inventories stabilized in the 1990s but increased significantly thereafter, with annual average growth rates (AAGRs) of 2.6 %–4.0 % during 2000–2010 but slower AAGRs of 0.5 %–2.2 % during 2011–2015, and the emissions became relatively stable, with AAGRs of 0.3 %–0.8 %, during 2015–2019 because of the stable emissions from the energy sector (mainly coal production). Spatially, there are large differences in emissions hotspot identification among inventories, and incomplete information on emission patterns may mislead or bias mitigation efforts for CH4 emission reductions. The availability of detailed activity data for sectors or subsectors and the use of region-specific emission factors play important roles in understanding source contributions and reducing the uncertainty in bottom-up inventories.

Comparative Analysis of Land Use/Land Cover Change and Watershed Urbanization in the Lakeside Counties of the Kenyan Lake Victoria Basin Using Remote Sensing and GIS Techniques

Article history: Received: 24 January, 2021 Accepted: 13 March, 2021 Online: 20 March, 2021 The ecosystems and landscape patterns in Lake Victoria basin are increasingly being modified by changes in land use/land cover. Understanding dynamics of these changes is essential for appropriate planning. This study evaluated changes in landscape environment, of the lakeside counties of the Kenyan Lake Victoria basin, which have occurred over a fortyyear period (1978-2018) and their potential impacts on the lake using remote sensing and GIS techniques. Landsat imageries of 1978, 1988, 1998, 2008 and 2018 were analyzed for each county to develop land use and land cover maps and to detect and quantify changes using the Maximum Likelihood algorithm. Supervised classification was utilized. The study showed that the six land use/land cover classes, identified in the counties, have undergone drastic modifications in a span of four decades. Over the years, built-up areas steadily increased in all the counties, forested and vegetated areas steadily declined in all the counties, areas under water bodies remained relatively constant in all counties, while the rest of the land use and land cover types experienced periodic rise and falls in areal coverage. Generally, the major gains in coverage by the various land use and land cover types occurred between 2008 and 2018 while major losses occurred between 1978 and 1988. The study suggests that future regional conservation measures should take cognisance of the general ecological and socio-political processes in the entire Lake Victoria basin for integrated watershed conservation.
Calibration and validation of the Dynamic Wake Meandering model Part I: Bayesian estimation of model parameters using SpinnerLidar-derived wake characteristics

Abstract. In this first part of a two-part work, we study the calibration of the Dynamic Wake Meandering (DWM) model using high spatial and temporal resolution SpinnerLidar measurements of the wake field collected at the Scaled Wind Farm Technology (SWiFT) facility located in Lubbock, Texas, U.S.A. We derive two-dimensional wake flow characteristics including wake deficit, wake turbulence and wake meandering from the lidar observations under different atmospheric stability conditions, inflow wind speeds and downstream distances up to five rotor diameters. We then apply Bayesian inference to obtain a probabilistic calibration of the DWM model, where the resulting joint distribution of parameters allows both for model implementation and uncertainty assessment. We validate the resulting fully-resolved wake field predictions against the lidar measurements and discuss the most critical sources of uncertainty. The results indicate that the DWM model can accurately predict the mean wind velocity and turbulence fields in the far wake region beyond four rotor diameters, as long as properly-calibrated parameters are used and wake meandering time series are accurately replicated. We demonstrate that the current DWM-model parameters in the IEC standard lead to conservative wake deficit predictions. Finally, we provide practical recommendations for reliable calibration procedures.
Excess Dental Cement and Peri-implantitis: A Systematic Review

Introduction: Cemented crowns are usually used on implant abutments instead of screw retained crowns. The remnants of cements are frequently disseminated to the surrounding tissues despite of clinician efforts to control the cementation. This review aimed to explore the evidence regarding the impact of cement excess and cement types on the development of peri-
Investigation of Electrochemical Behavior of Mordant Dye (C.I. 17135)

In this study, the electrochemical behaviour of Mordant dye (C.I. 17135) was investigated in Britton-Robinson (BR) buffer (pH 2.0-12.0) media by using different voltammetric techniques: square wave voltammetry (SWV), cyclic voltammetry (CV), differential pulse voltammetry (DPV) and direct current voltammetry (DCV). The electrochemical behavior of the dye has been investigated by using a glassy carbon electrode (GCE) and silver electrode (SE). The brode peak of the azo dye occurred at SW and DP voltammograms, is due to its adsorption on the glassy carbon and silver electrode surfaces. Two reduction peaks were observed at pH < 9.5, and one reduction peak was observed at pH > 9.5 for SWV and DPV techniques at a glassy carbon electrode. From the voltammetric data electrochemical reaction mechanism of the azo dye has been suggested at glassy carbon and silver electrodes.
