Pulsed LED line light for large-scale PIV—development and use in wave load measurements
Authors: Bakker W , Hofland B , de Almeida E , Oldenziel G , J Overmars E F 
Published: July 2021

Abstract
In this paper the development of a high-power pulsed LED line light and its use to apply particle image velocimetry (PIV) during wave impact measurements are described. An electrical circuit that generates high-current pulses is designed and built, which is used to overdrive a number of commercially available LEDs. The limit for this overdrive-capacity is determined as function of pulse duration for various commercial available LEDs. Two systems of cylindrical convex lenses are designed to act as a collimator and reduce divergence of the LED bundle and the resulting light sheet properties (maximum light intensity and sheet thickness) are investigated. An array of LEDs of 60 cm length (referred to as the LED line light) is designed and manufactured. For the two lens systems, the LED line light provides proper light sheet conditions to illuminate measurement regions in the order of either 0.3 × 0.3 m2, or 1 × 1 m2, at a sufficiently constant light sheet thickness of 5 mm. The application of the LED line light is demonstrated by quantifying the instantaneous flow field of a wave impacting on a blunt object in a wave flume. PIV measurements are conducted at an acquisition rate of 25 frame pairs per second, quantifying maximum flow velocities in the order of 1.0 m s−1 at a LED pulse width of 200 μs. The system, consisting of the LED line light, a CMOS camera and open source PIV processing software provides the possibility to perform 2D planar PIV measurements for a fraction of the costs of a commercially available laser based PIV system.

Abstract
The moiré-pattern with slightly interlayer-twisted bilayer two-dimensional (2D) materials has recently been receiving substantial attention. One of the major characters for these intriguing structures is the appearance of low-energy ultra-flat bands and thus a package of new physics associated with strong electron correlation emerges. However, such new physics may become vague unless the twist-angle θ is sufficiently small such as θ ∼ 1°, making practical applications and control-flexibility hard to handle. In this work, we explore the possible flat-band moiré physics in recently concerned 2D bilayer α-In2Se3 which is antiferroelectric with sublayer out-of-plane (OP) polarizations, addressing the potential role of polarization-bound charges in modulation of electron–electron correlation and interlayer hybridization, based on the extensive first-principles calculations. On one hand, it is found that the low energy band becomes extremely flat in the bilayer α-In2Se3 moiré-pattern with relatively large twist-angle, e.g. θ = 13.17°, which is more easily accessible experimentally. On the other hand, the impact of the sublayer OP polarizations on the band structure is asymmetric, and the flattening effect is much more remarkable for the end-to-end polarization alignment but weaker for the head-to-head alignment. This work thus opens a broad roadmap for technological access to artificial fabrication of novel moiré-patterned 2D materials by means of low-dimensional ferroelectricity.

Abstract
Pesticides are a group of chemicals that are intentionally applied to the environment with the aim of suppressing pests and plant diseases and protecting agricultural products. Most pesticides do not specifically target pests and diseases only during application, but also affect the products produced and human health due to the residue and the effect on non-target pests including entomopathogen. The purpose of this study was to determine the effect of pesticides applied in controlling pests and diseases of citrus plants towards the growth of entomopathogenic fungi in vitro. This test used three active ingredients of pesticides namely Mankozeb (fungicide), Profenofos and Lambda cyhalothrin (insecticides). Dosage of pesticides in the treatments were 0.25 times, 1-time, 2-times of the recommended doses and control (without pesticides). Five types of entomopathogenic fungi used were Metarhizium anisopliae, Hirsutella sp., Beauveria bassiana, Paecilomyces sp. and TB.8 (not yet identified). Each treatment with 3 replications. The size of entomopathogenic fungi showed the influence of pesticides on the growth of entomopathogenic fungi. A quarter dose of profenofos insecticide had the potential to inhibit the growth of all isolates, except M. anisopliae. All isolates did not show significant growth reductions after treated with various doses of Lambda-cyhalothrin insecticide. Mancozeb fungicide had a negative effect on the growth of all entomopathogenic fungi isolates. The highest spore density on the 21st days was Paecilomyces sp. under the Profenofos treatment. Lambda-cyhalothrin did not affect the spore productions in all entomopathogenic fungi isolates. Otherwise, spore production was not observed even at the lowest concentrations of Mancozeb treatment. Differences in the active ingredients of pesticide affected the growth and sporulation of entomopathogen.

Abstract
Zalacca fruit has a short shelf life which is about 5-7 days after harvest. Control Atmosphere Storage (CAS) and Modified Atmosphere Packaging (MAP) are alternative technologies that can be applied to increase the shelf life of fruit. In the CAS system, zalacca fruit was stored in a room with a composition of 9% O2 and CO2, a temperature of 8-12ºC, and 90% RH, while in the MAP system the fruit was packed in plastic crates in a capacity of 8 kg then the crates are coated with plastic which is given holes as many as 72 holes measuring 0.5 cm. The results showed that zalacca fruit can be stored in CAS conditions for 26 days with a weight loss of 1.25% and a damage level of 7.3%, while the weight loss and damage levels of zalacca fruit on MAP storage were 2.6% and 29.5%. Microscopically the fruit of zalacca CAS and MAP showed skin wrinkling which was thought to be related to the occurrence of water loss during storage. Based on the data obtained, the storage of zalacca fruit by CAS was more effective than MAP.

Abstract
The research objective was to analyze the characteristics of broiler farmers in the use of herbal feed ingredients as additive feeds, analyze farmers’ culture in applying herbal ingredients in feed and analyze farmer responses to the use of herbal feed ingredients (phytobiotic content) in reducing AGP (Antibiotic Growth Promoter) residues in broiler meat . The study was conducted in the Turen sub-district of Malang Regency. The number of respondents in the study was a total sampling obtained by 157 farmers. Data analysis using quantitative methods with multiple regression. The results showed that factors affecting farmers using phytobiotic-based additive feeds were education level, intrinsic motivation, extension intensity, income, broiler business experience, price of phytobiotic-based additive feed and AGP-based feed prices. The habit of providing AGP-based feed was quite high, but the response to phytobiotics was also high, but in practice there was still little because of the lack of knowledge of farmers to phytobiotic. Socio-economic factors of farmers affect 84.2% of the use of phytobiotics. The culture of antibiotic use was influenced by several factors including farmer education level, farmer income and phytobiotic feed prices. .
Comparative analysis of unbalanced moment of reinforced concrete slab-column connections
Authors: Qingxuan Shi , Lu Zhang 
Published: July 2021

Abstract
The existing comparative analysis of the unbalanced moment mainly compares the differences between the calculated value and the experimental value of the unbalanced moment in different national codes and different calculation methods. There is less analysis on the change trend of the important parameters in the unbalanced moment calculation methods in national codes. A comparison of the provisions for unbalanced moment of reinforced concrete slab-column connections was studied based on Chinese code (GB 50010-2010), American code (ACI318-14) and European code (EN1992-04). The effects of concrete strength, longitudinal reinforcement ratio, the use of shear reinforcement and gravity-shear ratio on the unbalanced moment were studied through the calculation example and experimental results of 186 specimens. The results indicate that the calculation values of Chinese and American codes are conservative and dispersive, because the longitudinal reinforcement ratio and gravity-shear ratio on distribution coefficient of unbalanced moment were not considered, while the calculation results of European code are the closest to the test values.

Abstract
The accurately program of search&rescue of the wounded is designed and an initial design idea of various subsystems is proposed in order to provide theoretical explorations and solutions for making the search & rescue of the wounded on a land battlefield immediate, intelligent and accurate and for lowering the death and disability rates of the wounded. A full combination of skill features and functional advantages is made between BDS and Armored ambulance, which is systematically applied to the search & rescue on the land battlefield. The rationality and feasibility of the program of search&rescue are guaranteed by functional combinations, comprehensive integration and experimental verification. The verification of the program of search&rescue is made in the form of war-game exercises. The result finds that the “BDS + Armored ambulance” pattern of search & rescue can accurately acquire real-time locations of the wounded, immediately provide on-site first-aid services and emergency aid & treatment for the wounded and rapidly receive and transfer the wounded, which demonstrate a better practice and application prospect of health services. As the BDS-3 is to be put into service in 2020, the informationized upgrading and transformation of Armored ambulance will be gradually completed and the “BDS + Armored ambulance” program of search &rescue will exert a more obvious influence on the search & rescue of the wounded on the land battlefield, which provide a capability support for realizing the idea of “Medical Treatment be with Soldiers”.
