Published: August 2024

Livestock farming faces inherent vulnerabilities, such as disease outbreaks and natural disasters. The utilization of livestock insurance can play a crucial role in alleviating risks and uncertainties associated with farming practices, ultimately fostering security for farmers. The research was carried out purposively in Nawalpur district during 2022 to identify the factors affecting adoption of livestock insurance among dairy cattle farmers. One hundred and twenty dairy cattle farmers were selected randomly from the study area. Primary data were collected using pretested semi-structured interview schedule, Focus Group Discussion and Key Informant Interview. Descriptive statistics and probit model were used to interpret the findings. Findings from the research revealed that age, membership in farmer’s organization, contact with extension worker and rearing of improved breed were statistically significant in the adoption of livestock insurance. Extension agencies of government, non-governmental institution and insurance companies should primarily focus on farmers who are old aged, rear improved breed, participate in farmer’s organization and have regular contact with extension worker for better adoption.

Published: August 2024

A key technology to minimize CO2-emissions is the production of hydrogen from water electrolysis. The proton exchange membrane water electrolysis (PEMWE) consists of a stacked system out of bipolar plates (BPP), porous transport layers (PTL) and a membrane electrode assembly (MEA). Research activities are ongoing to minimize material input, reduce costs and increase the performance. For example, the BPP on the anodic side of the stack is currently manufactured of bulk titanium and its substitution by a Ti-coated steel substrate is economically interesting. The main requirements for the BPP-coating are a high coating density, a low electrical resistance and a long lifetime in a harsh electrochemical environment. Coating application on substrates of s ≤ 0.5 mm thickness is conducted with three thermal spraying technologies: Cold Gas Spraying (CGS), High Velocity Air-Fuel (HVAF) spraying and High Velocity Oxy-Fuel (HVOF). Substrate preparation is examined as well. Coating development is conducted with regards to coating thickness, density and oxidation. The examination of coatings includes roughness analysis, structural and chemical analysis. The results allow an evaluation of the suitability of thermally sprayed Ti-coatings by the structural properties for the PEMWE application. Among the three tested processes, CGS is the most suitable for this type of application. The three chosen thermal spraying processes are examined for coating application on metal sheets in context of PEMWE for the first time.

Published: August 2024

All solid-state sodium-ion batteries (ASS-SIBs) have great potential for application to large-scale energy storage devices due to their safety advantages by avoiding flammable organics and the abundance of sodium. In this study, plasma spraying was used to deposit Na3Zr2Si2PO12 (NZSP) electrolyte for assembling high performance ASS-SIBs. NZSP electrolyte layers were deposited at different spray conditions using NZSP powders in different particle sizes. The factors influencing the microstructure and compositions of NZSP layers were examined by characterizing the compositions of splat and cross-sectional microstructures of the deposits. It was found that the preferential evaporation loss of Na and P elements occurs severely to result in a large composition deviation from initial powders and spray particle size is key factor which dominates their evaporation loss. The APS NZSP electrolytes present a dense microstructure with well bonded splats which is attributed to low melting point of NZSP. The apparent porosity of the as-sprayed NZSPs was lower than 3 %. The effect of annealing on the microstructure of APS NZSP was also investigated. The performance of typical APS NZSP was also evaluated by assembling an ASS-SIB battery with APS NaxCoO2 (NCO), Na3Zr2Si2PO12 (NZSP) and Li4Ti5O12 (LTO) as cathode, electrolyte and anode, respectively. Results showed that columnar-structured grains with a chemical inter-splat bonding were formed across the interfaces between electrodes and electrolyte. There is no evidence of inter-diffusion of zirconium, cobalt and silicon across the NCO/NZSP interface. With the preliminary battery, the solid electrolyte exhibited an ionic conductivity of 1.21 × 10-4 S cm-1 at 200 oC. The SIB can operate at 2.5 V with a capacity of 10.5 mA h g-1 at current density of 37.4 μA cm-2.

Published: August 2024

Tantalum and silver are recognized for their outstanding biocompatibility and antibacterial ability, respectively. However, owing to their distinct chemical and physical properties, synthesizing alloys and composites by using Ta and Ag presents a considerable challenge. In this study, Ta-Ag composites, exhibiting good antibacterial ability, were successfully produced by using a solid-state cold spray technique. Notably, intriguing correlations were observed between Ag microstructure and antibacterial ability. To unravel this correlation, a comprehensive experimental and simulation analyze were conducted. It is found that the volume ratio of Ta to Ag in the feedstock powder result in different deformation histories for Ag during the cold spray process. This, in turn, leads to the formation of distinctive Ag microstructures within Ta-Ag composites. The varied Ag microstructures results in different Ag dissolution ability and the formation of an insoluble AgCl layer exhibiting varying morphologies, when Ag exposed in a high chorine ion environment, like in human body fluids. This consequently influences the concentration of Ag ion and ultimately determines antibacterial ability. The study demonstrates that Ag release rate and the related antibacterial properties could be alternatively controlled by changing Ag contains or by creating different deposition process by adjusting CS parameter.

Published: August 2024

In Laser Cladding, a differentiation must be made between cladding by brazing and cladding by welding regarding process parameters and the resulting material properties. Results of investigations of bronze cladding on steel parts produced by Laser Deposition Brazing will be presented. This means that a strong metallurgical bond is realized by diffusion processes by Laser Deposition Brazing, but the steel base material is not molten. The coatings were characterized by hardness distribution measurements from the bronze cladding to the steel substrate, by measuring the size of the heat-affected zone and by porosity measurements. This combination of a steel substrate and a local bronze coating is used industrially in many tribological applications, such as plain bearings or hydraulic pumps etc. The bronze offers excellent tribological properties. In some cases, the bronze is used as a complete solid part. However, applying the bronze locally to a steel base body instead of using a complete solid bronze component, offers the advantage of the higher modulus of elasticity of the steel, which provides greater stability of shape with regard to possible elastic deformations as these coated parts are exposed to high mechanical loads, it is essential that a high coating quality is achieved by laser cladding and that the properties are extensively and purposefully characterized. The production technology, the characterization and the industrial applications of such bronze coated steel parts are presented and explained in this contribution.

Published: August 2024

One of the promising thermal barrier coatings (TBC) options for use above 1250 °C has been La2Ce2O7 (LC). This work explored the role of dual layered ceramic coatings in the top layer of the TBC system that has been prepared using atmospheric plasma spraying (APS). Above the NiCrAlY bond coat, 8 mol.% yttria stabilized zirconia (8YSZ) coating has been deposited with optimized APS parameters. Over the top layer (8YSZ), another layer that comprises composite with LC and 8 wt.% of 8YSZ (spray dried) has been deposited. Investigations into the hot-corrosion behavior of 8YSZ-LC based TBC subjected to Na2SO4+V2O5 salt at 950 °C for 4 hours. A porous layer made mostly of LaVO4, CeO2, CeO1.66 and YVO4 was developed on the LC+8wt.% YSZ layer after being subjected to a hot corrosion test in Na2SO4+V2O5 salt. Dissociation of LC and 8YSZ leads to the formation of new phases, such as CeO1.66, CeO2, LaVO4 and YVO4 as the corrosion by-products in the extreme environment. The findings indicated that delamination has occurred due to the phase transformation, cavities and cracks in the 8YSZ-LC based TBCs. The molten salt's hot corrosion mechanisms of the 8YSZ-LC based TBC are discussed in detail. Further, the potential use of 8YSZ-LC based dual coatings and scope for the future work have been derived from the current study.

Published: August 2024

The performance and, as a consequence, the application of functionalized fiber-reinforced plastic (FRP) are limited due to low adhesion strengths between the metal coating and the polymer-based substrate. Common pre-treatment methods, to successfully apply a metal coating by thermal spraying on commercial FRP, are mechanical blasting, etching or thermal treatment. Moreover, additional layers made of metal wire or sand have been integrated into the FRP surface. A promising material-sensitive pre-treatment method for FRP substrates is laser micro structuring. This method avoids uncontrolled damage of surface-near fibers and offers an increased interface area. Unique for pulsed laser structuring is the opportunity to achieve a clamping effect between the functional coating and the FRP by a trench-like structure.

Published: August 2024

Surface coatings play a pivotal role in enhancing mechanical and functional properties of various materials. High Entropy Alloy (HEA) annealed coatings have garnered significant interest due to their potential to improve wear resistance and overall durability. This research presents a comprehensive study focused on the characterization of HEA annealed coatings. It focuses on evaluating their roughness and wear performance. In this research, a systematic approach is adopted to assess the effects of annealing on coating surface properties. The investigation begins with the deposition of the Al 0.1-0.5 CoCrCuFeNi and MnCoCrCuFeNi coatings using a well-established cold spray (CS) technique, followed by a controlled annealing process. The coating surface roughness is analyzed using profilometry and microscopy techniques. This offers insights into the changes induced by annealing. The wear performance of the annealed coatings is evaluated through tribological tests.
An Investigation on the Effect of Deposition Technique on Micro-Structural and Mechanical Properties of WC-17Co Deposited Using Direct Energy Deposition (DED) and High-Velocity Oxygen Fuel (HVOF)
Authors: Grabowski Theresa , Azarmi Fardad , McDonnell Martin
Published: August 2024

Recently, laser deposition technologies have made significant advancements in their ability to manufacture high temperature metals and ceramics. One of these technologies, known as Direct Energy Deposition (DED), has the potential to deposit a wide range of materials from polymers to refractory materials, ceramics and functionally graded materials. This study evaluates major microstructural characteristics of WC-Co additively manufactured by DED technology. This material is commonly used for deposition of protective coatings due to its high hardness and excellent wear resistance. To this end, hardness and wear resistance of the DED processed samples were also investigated in this study. WC-Co coatings are generally deposited using various thermal spray technologies. However, it is speculated that DED deposited WC-Co could provide superior properties such as higher hardness and wear resistance. A DED manufactured WC-Co sample was examined by Optical Microscopy (OM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), and X-ray Diffraction (XRD). Those studies could provide information about important microstructural features, chemical compositions and phase distribution. All the tests were also repeated on High-Velocity Oxygen Fuel (HVOF) deposited WC-Co with the same composition. Both DED and HVOF produced WC-Co coatings experience decomposition of the carbides into compound phases; however, the DED deposited sample displays unique dendritic and eutectic structures that improve the hardness and wear properties compared to the homogenous HVOF coating. In addition, DED produced samples show higher hardness and relatively better wear resistance compared to the HVOF deposited ones. The obtained results could establish a relationship between microstructural characteristics with hardness and wear properties of both samples.

Published: August 2024

The deformation behavior of particles plays a significant role in achieving adhesion during cold spray. The deformation behavior of the particles is associated with the fracture of the oxide layer and recrystallization, which are the key elements of the quality of cold spray. Studies of particle compression have been made to understand the deformation behavior of a particle. However, the deformation behavior of particle under controlled load and precise and high strain rate is yet to be studied. Here, we show the oxide layer fracture pattern and recrystallization regime under controlled load with a precise and high strain rate. We found that the cracks in the oxide layer initially appeared on the equator of the particle and propagated towards the edge of the top surface. Meanwhile, on the top surface, the circumferential crack was developed. On the other hand, the nanoindentation result showed that the compressed particle under a high strain rate has an unusual load-displacement behavior. Our results demonstrate that the oxide layer fracture behavior corresponds to the adhesion mechanism suggested by previous studies. Our study also revealed that recrystallization takes place within the particle under a high strain rate. We anticipate this finding to give a general insight into the deformation behavior of particles during cold spray. For instance, since the recrystallization behavior at a given strain rate can be predicted through this study, the resultant grain size and shape, which is associated with mechanical properties, can also be predicted. Furthermore, the amount of strain and strain rate to form optimal adhesion can be evaluated.
In Situ Spray Bead Acquisition and Analysis for Coating Thickness Predictions

Published: August 2024

Coating thickness is considered to be one of the most important characteristics of thermal spray coatings. Therefore, it has long been the goal to be able to predict the coating thickness that ensues when coating an arbitrary part. A commonly applied approach is to determine the coating deposit based on a series of spray spot tests and use that for modeling the coating. Another option is to conduct spray bead tests, which better reflect the conditions during the coating. This work suggests a novel approach for in situ acquisition of the spray beads and their analysis. The acquisition is based on a 3D camera to scan the sample before and after depositing of a spray bead. The approach allows for their streamlined evaluation, enabling better understanding of spray bead formation and their modeling. The suggested analysis of spray beads includes uncertainty evaluation. This enables estimation of model prediction uncertainties which has been omitted in previous works on the topic. The analysis shows that a relative expanded uncertainty of 10% (at 95% level of confidence) can be expected for the coating thickness prediction for the simplest scenario of coating a flat sample sprayed perpendicularly at a constant spray distance and spray speed.

Carbon fiber (CF) composites are widely used in the aerospace industry due to their light weight and favorable mechanical properties. Nevertheless, applying protective coatings (e.g. erosion resistance) through thermal spraying presents specific challenges with defects such as distortion, oxidation, and poor coating adhesion. This study presents a new technique that combines electroless plating processes and thermal spray for depo-siting metals onto polymer-reinforced composites. Samples of low melting polyaryletherletone (LMPAEK) thermoplastic polymer reinforced with carbon fibers aligned in the normal direction (ZRT film) are plated (with copper, silver, or nickel) to provide an adhesion layer for the thermal spray processes. Subsequently, pure tin and titanium (i.e. Ti-6Al-4V) is deposited on the samples using High Velocity Air-Fuel (HVAF) and atmospheric plasma spray (APS) processes. Cross-sections of the resulting coatings are compared, and the materials are characterized for surface roughness, cracks and pores.

Published: August 2024

In plasma spraying, H2 or N2 is commonly added to the primary Ar plasma which may increase the specific enthalpy, thermal conductivity and thus improve the process efficiency. The objective of this study is to provide a process characterization of a three-cathode plasma torch with various binary gas compositions. Several process diagnostics are used to characterize the impact of binary plasma gas mixtures in plasma spraying. High-speed video analysis is utilized to capture the jet fluctuations of the studied process parameters. In addition, current and voltage measurements are performed to further complement the plasma diagnostics. The impact of the binary plasma gas mixtures is determined using particle diagnostic system DPV-2000 by measuring the particle in-flight properties of Al2O3 feedstock. Furthermore, the deposition efficiency (DE) of the investigated process parameters is determined. The results show that at the identical volumetric flow rate and current, the addition of H2 yields the highest particle temperatures, followed by Ar/N2 mixtures and pure Ar plasma. In reverse order, pure Ar plasma results in the highest particle velocities. In addition, the increased DE of plasma spraying with binary gas mixtures for Al2O3 coatings offers the potential to increase the deposition rate of other ceramic materials. This study provides a comprehensive correlation between plasma and particle diagnostics and the deposition efficiency of binary plasma gas mixtures.

Eggs are among the most nutritious foods, but they are perishable. Immediately after they are laid, ageing processes begin in shell eggs, altering their chemical, physical and functional properties. This study aimed to determine the effect of storage temperature on the shelf life of hen eggs according to changes in some important physical properties (weight, pH, Haugh Unit, Albumen Index, and Yolk Index). The studied temperatures were selected as possible refrigerator and room temperatures (10, 20 and 30°C). It was revealed that temperature significantly influenced egg quality, with the most significant effects observed in the Haugh unit and pH due to weight changes. The highest quality loss occurred at 30°C. The activation energies for each quality parameter were determined using the Arrhenius equation. The pH of the fresh egg was 7.6 ±0.1 and increased to over 8.5 – 9.0 during storage, depending on the temperature. Haugh unit, albumen index, and yolk index decreased, and the area of both yolk and albumen increased during storage.

The purpose of this research is first to discover the development of case examination procedures in the current State Administrative Court. Second, to determine the current case examination procedure in the State Administrative Court associated with the Theory of Effectiveness. The type of research used is normative research which places the law as a system of norms, with descriptive analytical methods, namely by describing existing problems and analyzing them. The results of this study show First, there has been an expansion of the competence of the State Administrative Court in receiving, examining & adjudicating a case. The State Administrative Court Law that has not regulated this has resulted in a procedural law vacuum so that the Supreme Court in the 2011-2017 timeframe issued its legal products in the form of Supreme Court Regulations, namely the State Administrative Court Law which previously only regulated 3 types of case examination procedures, namely ordinary examination, simple examination, and rapid examination, currently there are several new case examination procedures regulated in 5 Supreme Court Regulations. Second, in terms of one of the factors in the Theory of Effectiveness, namely the legal factor itself (the law), this factor states that to determine whether a written law functions or not depends on the rule of law itself, one measure of the success of this factor is that the existing rules regarding certain areas of life are quite synchronous / there is no horizontal conflict & hierarchy, but the current main regulation, namely the State Administrative Court Law, in fact has not been synchronised with other regulations issued by the Supreme Court in the form of Supreme Court regulations which aim to fill the void of procedural law, especially the law of examination.

Published: August 2024

In this study, an attempt was made to investigate the blood donation behavior of rural people in Bangladesh. The main objective of this research is to explore the beliefs and perceptions of rural people regarding blood donation. For this purpose, the study was conducted in Nuruddinpur village at Sujanogor Upazilla in the Pabna district, which is situated in the west central Bangladesh. A combination of in-depth interviews, key informant interviews (KIIs) and storytelling was used in the study. Moreover, few focused group discussions (FGDs) and yard meetings were also used as data collection methods in this study. The results show that there are cultural components involved in providing and receiving blood. Blood and blood donation have different and versatile meanings that change according to the individual’s role in donation. People relate blood to several cultural elements and issues while talking about blood donation, which shows that the choice and context of blood donation are influenced by personal beliefs, social and religious ties and experiences, and, of course, gender. In addition, some blood-related stigmas were also revealed in the study area. This study recommends that these sociocultural beliefs and lay perceptions should be considered and that pathways be taken to improve blood donation activities.

This study aimed to determine whether the hours of sunshine and/or the amount of precipitation affect the number of cows and heifers that will show oestrus in the following days and the extent to which these climatic elements affect the average number of artificially inseminated cows and heifers per day. During the course of three consecutive years, a total of 21,043 cows and heifers were artificially inseminated in Koprivnica-Križevci County, Croatia. Descriptive statistics, analysis of variance, and Tukey pairwise comparisons were performed between the number of artificially inseminated cows and heifers, cloud cover, rain intensity, and number of days after rain. Significant differences were recorded in relation to cloud cover and the average number of cows and heifers artificially inseminated per day. The average number of artificially inseminated cows and heifers per day did not differ significantly among seasons (p>0.05). Significant differences were observed in the number of artificially inseminated cows and heifers per day in relation to rain (1, 2, 3, 4 or more days after rain) and in relation to the amount of precipitation (dry, light rain, rain, heavy rain, extreme rain). We can conclude that in a temperate climate, significantly fewer cows and heifers were in natural oestrus and artificially inseminated on rainy or cloudy days, while significantly more cattle were artificially inseminated on dry days following rain and on days with more hours of sunshine, regardless of season.

Published: August 2024

Since its inception, the Goods and Services Tax (GST) has been established as a pivotal revenue source for both the central and state governments in India. A comprehensive understanding of the evolving role of GST in shaping India's taxation landscape and influencing both central and state fiscal strategies is aimed to be offered by the research. An analysis of GST collections was presented, and variations in states' revenue performance before and after the implementation of GST were discussed in the study. This examination could include how different states adapted to the new tax regime and whether disparities in revenue generation were present. The data of GST collections across states was utilized, and the variation in the average growth of government revenue after the implementation of GST was analyzed. Descriptive statistics, Paired Sample T tests, and Regression were the statistical techniques used for the analysis. The findings of the study indicate a fluctuating trend in India's GST collections, with Maharashtra consistently leading but experiencing a notable decline in FY 2024. The average growth of GST collections shows an increasing trend until 2023, with a decrease in 2024. Paired T test results reveal a significant positive impact on government revenue growth post-GST implementation across all states. The regression analysis underscores a significant relationship between GST and GDP, emphasizing its broad economic influence. Implications include the need for nuanced policy responses to regional variations and consideration of GST dynamics in economic policymaking for sustained positive effects on government revenue growth and economic stability.

Published: August 2024

The following article includes a chart illustrating the dietary components of various food classes that are involved in the pathogenesis of colorectal cancer (CRC), as well as information on the key players in the digestive tract microbiota and the many dysfunctions involved in the onset or progression of CRC. With its complex course throughout history, colorectal cancer has advanced the understanding of its initiation and improvement. The understanding of how colorectal cancer starts and improves through eating less has advanced over time. By and enormous, the utilization of ruddy and organized meats has been related to an expanded chance of start. These meats contain compounds such as nitrates and nitrites that can serve as diagram carcinogens inside the colon. Understanding how diets affect epigenetic modifications inside the intestinal mucosa is particularly important since abnormally methylated genes may serve as early detection and prognostic markers for colon cancer. Epigenetic changes, such as changes in methylation, are potentially reversible and, therefore, offer interesting targets for supportive and preventative therapy, unlike intrinsic changes in cancer. The growing role of microbial metabolites and a few clearly beneficial dietary additions in the management of CRC are outlined in this article.
