Authors: Chai K.K. , Wang K.K. , Chang S.Q. , Zhang H.Q. 
Published: July 2021

Abstract
A Monte Carlo simulation-based optimization of a SERS-based thermal neutron detector is aimed at improving detection efficiency for thermal neutrons. The moderator and collimator have been designed for a 241Am-9Be source to maximize the thermal neutrons flux in the irradiation area. Simulated thermal neutron detection efficiency can be increased to approximately 50.5% when polyethylene is added as neutron reflector and 10B enriched 4-MPBA is used. With Monte Carlo software GEANT4, the SERS-based thermal neutron detector has been proven to have almost no effect on original thermal neutron flux as well as the distribution and could be used for thermal neutron detection accurately.

Published: July 2021

Abstract
Nowadays, many scientists work on the geometry change between source-to-detector arrangement to calibrate the 3”× 3” γ-ray NaI(Tl) detector based on the available sample shape in the laboratory. The calculated full-energy peak efficiency is more sensitive in radiation activity determination and can be estimated build on complex analytical and numerical techniques. In the present study, the full-energy peak and total efficiencies beside the peak-to-total ratio (P/T) for γ-ray NaI(Tl) detector concerning vertical hexagonal ^152Eu radioactive source is calculated for all γ-rays involved in the cascade and estimate the suitable correction for coincidence summing effects (COI) by mean of the numerical simulation method (NSM). The extra factors which cause the γ-ray attenuation taken into consideration as well, such as, source composition materials, “self-attenuation within the source itself”, the detector end cap with the other supporting materials around the detector crystal, the source container material, and the holder used during the measurement process. The theory of this methodology depends on the efficiency transfer technique; calculate the effective solid angle, that be positioned in between the source-to-detector system, besides estimating the path lengths of the γ-rays inside the hexagonal ^152Eu radioactive sources and the active medium inside the detector itself as well. The results gained in the present work gave an agreement between simulation and measured data. The results show that to improve the accuracy of the γ-rays detector efficiency, many technical and methodological aspects of the present method are fitting and possible for applications inside the radiation laboratory, industrial, and medical sectors.
Operational planning of WEF infrastructure: quantifying the value of information sharing and cooperation in the Eastern Nile basin

Published: July 2021

Abstract
Integrating the planning of a multi-reservoir system in nexus with agricultural and electricity infrastructure could alleviate security concerns for these resources in regions where demand is growing while water and land scarcity are exacerbated by climate change and anthropogenic pressures. This study focuses on the benefits of resource integration and cooperation in the Eastern Nile basin. To overcome common limitations of equilibrium and soft-linked partial equilibrium models (e.g. high levels of spatial aggregation, non-insightful cooperation scenarios and a lack of heterogeneity), we propose a regional hard-linked WEF-nexus model that explicitly represents resource connectivity networks for water and electricity, and describes heterogeneity in resource availability, production potentials and physical constraints. Using a non-linear operational process, we optimise reservoir operations, water allocations, cropping patterns, electricity mixes and trade quantities on a monthly time-step over multiple years in a receding horizon fashion to maximize economic benefits for each country and regionally. This iterative implementation allows the modelling of operational changes as feedback against exogenous climate disturbances and enables information exchange between upstream-downstream countries. Thus, we describe four different levels of transboundary cooperation with their corresponding constraints and policy objectives. Compared to the reference scenario of unilateral planning, our results indicate an increase in regional economic returns for scenarios in which river flow information is shared between countries (+9%), river flow and trade information are shared (+10%) and WEF resources are coordinated regionally (+15%). These increased returns successively come from an increase in the effectiveness of agricultural water consumption, especially in Sudan, a change in trade patterns for agricultural products and a shift in cropping patterns. These findings underscore the importance of adequate representations of spatial and temporal heterogeneity of resources and their connectivity, as well as the need for a more diverse set of collaboration scenarios to facilitate planning in transboundary river systems.

Abstract
The straw was buried in field in transitory and busy farming season whether it’s paddy or dry land. Mechanized straw application was beneficial to solve the problem of straw burning, and also conducive to the fertility of soil and beneficial to soil improvement. It was an important measure to develop ecological agriculture and agriculture sustainable development. In order to solve the problem of crop residue burning, we designed a straw burying rotary tiller. It can bury crop straw not only in wet land, but also in dry land. It is suitable for tillage in middle and lower reaches of Yangtze River, where the principal crop rotation is wet land rice after dry land crop annually. Based on our previous research achievements, the cultivator for high stubble returning in paddy field and so on, are widely used. So there are two main kinds of cultivating blades in this rotary tiller. They are rotary blades IIT245 and spiral blades. The former blades are used to cut soil, while the latter blades are to bury straw. The results provide the basis for the structure optimization of the cultivator for straw returning and the improvement of its working performance, and also provide a suitable implement to achieve high stubble straw mulching and soil tillage in paddy field and dry land.

Published: July 2021

Abstract
The acidified structure of acetaminophen (ACA) and 3-Oxo-3-(phenylamino) propanoic acid (3-O-3) were used to couple bovine serum albumin (BSA) to prepare haptens, respectively. A highly sensitive and specificive competitive indirect enzyme-linked immunosorbent assay (ciELISA) method was developed for the detection of acetaminophen using 3-O-3-BSA for New Zealand white rabbit immunization to produce antibodies. The IC50 was 6.66 ng/mL, the detection limit was 0.32 ng/mL, and the quantitative detection range was 0.91-48.54 ng/mL. Comparing the performance of ACA-BSA antibody and 3-O-3-BSA antibody recognition of acetaminophen, it was found that the carbonyl site of 3-O-3 plays a major role in antigen-antibody recognition, while para-phenolic hydroxyl does not play an important role in the recognition process. The study provided theoretical guidance for the preparation of acetaminophen recognition antibodies, and established a rapid detection method for acetaminophen.

Abstract
The softening of plum fruit is an important factor affecting its promotion in production. In order to explore the changes of extension (EXP)during the ripening and softening stage of plum fruit, ‘jinmi’ plum and ‘qingcui’ plum were used as experimental materials to study the difference of EXP activity and PsEXPA10 expression during plum maturation and softening period. The results showed that as the fruit matured, the hardness of the fruit decreased, but there was a difference in the magnitude and rate of decrease between the two varieties, and the decrease of ‘Jinmi’ plum was even greater. The expression trends of EXP and PsEXPA10 were basically the same. At 81 d after flowering, the expression of PsEXPA10 in peel and flesh of ‘jinmi’plum was the highest, and the activity of EXP reached the highest at 88 d after flowering. The expression levels of EXP and PsEXPA10 in peel and flesh of plum were gradually increased, and the highest values of PsEXPA10 expression in flesh of plum were all at 109 d after flowering, except that the expression level of PsEXPA10 in flesh of plum was at 102 d after flowering. The results showed that EXP was closely related to plum fruit ripening and softening. And this study also laid a foundation for further exploring the molecular mechanism of EXP’s role in plum fruit softening.

Abstract
Five year old “Shine Muscat” grape was used as material to spray amino acid calcium and water-soluble calcium solution on grape leaves and ears during fruit expansion and color changing stages. The effects of exogenous calcium fertilizer on the formation of fruit rust and fruit quality of “Shine Muscat” grape were studied in a randomized block design with 1000 times of amino acid calcium solution and 1500 times of water-soluble calcium solution, and the spraying water was used as the control. The results show that: compared with calcium fertilizer in fruit expanding stage, it is more beneficial to the accumulation of sugar components in pericarp to spaying calcium fertilizer in turn-color stage. The content of sugar in pulp can be increased by spraying calcium fertilizer compared with water in fruit expanding stage. Spraying calcium fertilizer in turn-color stage can promote the degradation of malic acid and citric acid in the pericarp of mature grape and inhibit the degradation of tartaric acid. Spraying calcium fertilizer in fruit expanding stage can promote the degradation of citric acid in mature grape pulp, while calcium amino acid can inhibit the degradation of oxalic acid and tartaric acid and promote the degradation of malic acid. Spraying calcium fertilizer in turn-color stage can promote the degradation of organic acids in mature grape pulp. Combined with the content of soluble sugar and titratable acid, spraying 1500 times of soluble calcium in fruit expansion period is beneficial to improve the fruit quality of “Shine Muscat” grape.

Abstract
In order to determine the potential effects of potato plant infected by Potato virus Y (PVY) on the biology of aphid vectors, plastic box experiments were set up to study the preference of two of the most efficient PVY vectors, Myzus persicae (Sulzer) and Macrosiphum euphorbiae (Thomas). Aphid-plant selections were assessed 4h and 8h after aphid set in observation chamber presenting dual choices using two potato varieties, cv. Désiré e and cv. Bintje. Experiments show that both M. persicae and M. euphorbia preferentially settled on cv. Bimtie potato plants infested by PVY when compared to healthy potato plants after 4h and 8h. Compared healthy cv. Désirée plant and infested cv. Désirée plant, M. persicae tended to choose healthy plant, no significant preference for M. euphorbiae was found. When both cv. Bintje and cv. Désirée plant were infested by PVY, M. persicae tended to choose cv. Désirée plant, whereas M. euphorbiae made a choice to cv. Bintje plant. While the healthy plants were also compared, no significant preference for M. euphorbiae was observed, M. persicae preferred to cv. Désirée plant in dual-choice experiment. Results of our studies could help to further increase the knowledge on aphid dynamics and viral epidemiology in the potato cropping systems.
The Effects of different agricultural management measures on CH4 emission from paddy fields in southwest Shandong Province
Authors: Shen Yi Lin , Yu Shu 
Published: July 2021

Abstract
The field experiments were conducted on garlic stubble rice fields in southwestern Shandong Province. The experimental program was designed and the influence of different agricultural management measures on CH4 emission flux and the factors affecting CH4 emission were analyzed. The results show that although temperature affects CH4 emissions from paddy fields, it is not the only influencing factor. Compared with submerged irrigation+no basal fertilizer method, the CH4 emission flux of intermittent irrigation+basal fertilizer method is significantly larger; under the same submerged irrigation method, applying basal fertilizer is beneficial to CH4 emission. In the submerged irrigation+basal fertilizer mode, tillering fertilizer is more conducive to methane emission than panicle fertilizer. The use of intermittent irrigation method to apply appropriate amount of base fertilizer and tiller fertilizer can effectively control the increase of rice yield and the reduction of CH4 emissions in the rice field. The above operations can increase agricultural production and income and reduce greenhouse gas emissions.

Abstract
In this study, the possibility of producing new geopolymer concrete from olive oil waste in Jordan is presented. Olive oil residues in Jordan and many Mediterranean countries constitute a major environmental and health problem. So far, the waste is disposed of by means of sanitary landfill, and this poses an environmental risk and pollutes the groundwater, the main source of water in Jordan. The ash remaining from burning olive oil residues was used to produce geopolymer concrete by adding sodium hydroxide and without using any Portland cement. Mixtures were prepared using the central composite design. The focus was on the two most important factors affecting the properties of geopolymer concrete, which is the amount of ash and the amount of alkaline solution. After curing the concrete and passing 28 days, the compressive strength, slump, absorption, and porosity were measured. The Results of compressive strength, absorption and porosity was excellent in comparison with the results obtained from conventional concrete. Despite the promising results the slump of the proposed concrete is low, and the slump loss was very fast. Further studies are needed to improve the workability of geopolymer concrete from olive oil waste. This concrete allows to recycle a large amount of olive waste in Jordan and many other countries which reduce the impact on health and environment.

Published: July 2021

Abstract
It is common to see how the installation of photovoltaic systems is being used in the commercial sector to minimize costs on the electric bill, so if the aim is to obtain the greatest benefits from the photovoltaic system, it is necessary to carry out a correct sizing of its nominal DC capacity prior to installation. To achieve this in a more reliable way, the initiative was taken to develop a program with LabVIEW where it is possible to find the most profitable sizing based on the selection of the best scenario from a variety of simulations that it will carry out, this choice is based on the Net Present Cost (NPC) resulting from simulations. For the correct operation of the program, meteorological data of the hourly annual global irradiance were included. The data for the consumption analysis for each case was obtained from the load profiles of 8 selected banks. This research was carried out in the county of Santa Rosa de Copán, Honduras. The program developed in this research was able to determine the optimal result for each banking agency according to each scenario analyzed. The cases were categorized depending on their annual energy consumption, which are between 30 and 200 (MWh/year). Each bank was analyzed in 3 scenarios: no surplus compensation, net billing, and net metering. The development of this research determined the average nominal DC capacity required by an installation located in the proposed consumption categories and that with the current scheme that is managed in the country (without compensation of surpluses), it is economically attractive to optimize a grid-connected photovoltaic system for self-consumption, due to the significant amount of economic benefits it represents for the user, which in this research are between 28,000 and 165,000 (USD).

Abstract
The new energy revolution has put forward new requirements for energy production and consumption. This study systematically analyses the characteristics of energy production and consumption in Sichuan Province from 2015 to 2018. According to our analysis, natural gas and hydropower were the main sources of energy production in Sichuan Province, while the outputs of coal and, in particular, oil did not match consumption demand. Meanwhile, the industrial sector and household consumption were the main energy-consuming sectors in Sichuan. This study opines that, on the one hand, Sichuan Province should continue to develop and expand the production and consumption of clean energy and explore expanding the production of wind and solar energy. On the other hand, the province should devote attention to research and development for improving the efficiency of high-carbon fossil energy utilisation. Additionally, Sichuan Province also needs to focus on increasing the inventory of coal- and oil-based energy. The three aspects above require technological innovation. Hence, developing and introducing related technologies and talents is a long-term energy development solution for Sichuan Province.
