Abstract
Studies on the interaction effects of silicon (Si) and biochars in potentially toxic element (PTE)-contaminated soils are limited. Thus, the aim of this study was to investigate the interaction effects of biochars, from sheep manure (SMB) and rice husk (RHB) produced at 300 and 500 °C, and 2 levels of Si (as Na metasilicate), on growth and chemical composition of corn (Zea mays) in a Ni-polluted calcareous soil. It was found that the combined application of Si and biochars significantly reduced soil available Ni (17-32%) and the corn shoot Ni concentrations (29-58%), associated with soil pH increase (r=0.56-0.60, P<0.01). Among the biochars, SMB increased soil pH the most, and increased soil EC to saline levels, attributed to the higher ash content of SMB. Similarly, increasing Si application levels resulted in increasing soil pH and EC values. Application of all the biochars resulted in significant biomass increases with most positive effect from RHB. Despite the positive effect seen on soil Ni immobilization, the combined application of Si and biochars generally resulted in a decrease in corn shoot biomass yields compared to biochars alone, attributed to the significantly higher soil pH, EC and Na content which resulted in suppression of macro and micronutrient uptake by the corn.

Abstract
In most parts processing, the offset load of the worktable will be caused by many factors, such as the asymmetry of the workpiece shape and the offset of the clamping position. In this paper, the oil-cushion tilting double rectangular cavity hydrostatic thrust bearing is taken as the research object, and its static characteristics under abnormal load conditions are studied. The effects of rotation speed, offset distance and load on its static features are analyzed. The results show that the influence on the oil film pressure field under the eccentric load conditions is in descending order of load, speed, and offset distance. The effect of load and speed on the oil film pressure is positively related to the offset distance. The appropriate size of the offset distance has a specific gain on the bearing capacity improvement. The influence on the oil film temperature field under the abnormal load condition is in descending order of the rotation speed, the load and the offset distance. After the offset distance increases, the effect of load on the oil film temperature slightly increases, and the oil film temperature rise is within the safe operating range of the lubricating oil.

Abstract
The vertical flow filtration method has been used for this research based on four distinct circumstances of filtration through coconut husks, filtration through raw sugarcane bagasse, filtration through combination of coconut husks with limestone and filtration through sugarcane bagasse combined with limestone. Coconut husks is one of the biodegradable materials that high in water absorption. For sugarcane bagasse, it is one of the most abundant lignocellulosic agro-industrial residues remaining after the crushing and extraction of juice from sugarcane stalks. Both of materials can be used as filtration at home for domestic purpose. Before the filtration are carried out, coconut husks and sugarcane bagasse have been washed with distilled water to make sure the materials were completely free of any other substances. They will be dried in the oven for 24 hours at 100°C to ensure that the materials were completely dry and that the filtered water did not cause foreign smell or taste. Coconut husks and sugarcane bagasse have been compacted to a height of up to 3cm along particles of these materials were sufficiently dense to ensure filtering process efficiency. The test on the physical properties and heavy metals of greywater before and after filtration process have been carried out. The tests have been measured parameter of physical properties of pH, turbidity and colour as well as heavy metals namely Copper, Zinc and Iron defined as being among essential heavy metals usually found in greywater. The results of these tests are recorded and compared with standard to know the effectiveness of coconut husks and sugarcane bagasse for treatment of greywater.

Published: March 2023

Abstract
Plants play important roles in maintaining air quality and biogeochemical cycles, although many mechanisms remain poorly understood. Recently, spontaneous production of hydrogen peroxide (H2O2) has been reported from the condensation of water vapor as microdroplets. Here, we report detection of H2O2 in proximity to plants undergoing photosynthesis in a closed environment, confirmed using commercial peroxide test strips and spectrophotometric titration. Our results have potential major implications for the role of plant-mediated atmospheric cleansing, climate change, and urban and indoor air quality.
MKGPC: Multimodal Knowledge Graph Propagation for Recommendation Systems
Authors: Cooper Tahlia , Reid Charlotte , Kent Darcy , Harper Liam , Patel Kiana 
Published: March 2023

Abstract
With the exponential increase of information available on the Internet, the problem of information overload has become more and more urgent. Recommendation systems have been proposed to solve this problem by recommending a small subset of information from a large pool of data for users to quickly digest. Collaborative filtering has been the main direction of recommendation algorithm research, but it faces challenges such as the cold start problem and sparse interaction data. To address these challenges, researchers have introduced auxiliary information such as point-of-interest, comment, social networks, and contextual information. Knowledge graphs have been introduced as auxiliary information to improve the performance of recommendation systems. Knowledge graphs can fuse multiple data sources, expand the semantic information of data, and infer more potential information of data. However, current knowledge graph-based recommendation systems tend to ignore multimodal information. In this paper, we propose a new model, termed as MKGPC, that utilizes the propagation of information on the multimodal knowledge graph and considers multimodal information fusion. We compare the proposed model with state-of-the-art models. The proposed model shows promising results on two real-world datasets.
Nutritional Factors Affecting Reproduction and Practical Nutrition For Beef Cattle Ranchers
Authors: Corah Larry R. 
Published: March 2023

Numerous factors will influence the reproductive efficiency of a commercial cow herd, but nutrition is one of the most important. Reproductive efficiency is more than just the percent of cows pregnant. It includes:1. Percent cows and heifers bred early in the breeding season2. Percent pregnancy3. Percent cows weaning a calf4. Percent beef females calving unassisted
Many factors influence each of these four factors, but nutrition will have a major effect on each of these items.
Interferon Activity in Bovine Colostrum and Milk
Authors: Jacobsen Karen L. , Arbtan Kaveh D. , Halper Jaroslava 
Published: March 2023

Studies have shown that IFNs have potent immunologic (1,2) and antiviral (3,4) activity in both in vitro and in vivo testing in the bovine species. In calves given IFN orally, enteric disease due to rotavirus or mixed rotavirus and coronavirus infection was prevented or reduced(5). Interferons are also involved in immunity to protozoal infections (6), and a polypeptide with many characteristics similar to an alpha IFN has been identified that stimulated macrophages to inhibit intracellular development of Eimeria bovis (7). In preliminary studies, calves administered partially purified natural bovine alpha IFN intravenously had less coccidial diarrhea than control calves (8).
Although lymphocytes isolated from human colostrum and milk are capable of producing interferon ( IFN) when stimulated in vitro (9,10), assays of human colostrum and milk for IFN have usually yielded negative results (9-11). Since bovine peripheral blood lymphocytes, when stimulated with virus, are capable of producing alpha IFN (12), it would seem logical that these cells in mammary secretions would also have this ability. The only citation of the spontaneous occurrence of IFN in milk or colostrum from any species is a brief mention that a sample from one woman's breast milk contained antiviral activity (11). It was not known whether this woman was infected with a virus (11). It has been well documented, however, that when mother mice were inoculated with Newcastle disease virus, their milk contained measurable lFN (7). Furthermore, the newborns suckling such mothers had a significantly greater survival rate than that of controls after lethal challenge with vesicular stomatitis virus (7).
Since most mammalian infants have a lower incidence of neonatal disease when raised on maternal milk as opposed to milk replacer (13,14), it was hypothesized that interferons in mammary secretions may play an important role in neonatal immunity. Since bovine milk and colostrum had not been heretofore examined, the objective of this study was to determine whether IFN could be found in detectable levels in normal bovine colostrum and milk.

Does Antimicrobial Use in Animals Affect Human Health?
Authors: Apley Mike 
Published: March 2023

Yes! As veterinarians we positively impact human and animal health every day by using antimicrobials to treat or prevent disease. It is also necessary to recognize that this use may contribute to susceptibility shifts in pathogens with zoonotic potential. As a profession, and as an industry, we need to work toward carefully determining both positive and negative effects due to antimicrobial use in animal agriculture.
Our multiple responsibilities are best summarized by the veterinarians oath. "Being admitted to the profession of veterinary medicine, I solemnly swear to use my scientific knowledge and skills for the benefit of society through the protection of animal health, the relief of animal suffering, the conservation of livestock resources, the promotion of public health, and the advancement of medical knowledge ...

Disease Outbreak Investigation in the Beef Herd
Authors: Ribble Carl S. , Janzen Eugene D. , Campbell John 
Published: March 2023

Disease outbreak investigations can be an important, challenging part of beef practice. They require one to develop, by planning and experience, a thorough investigative approach which can be used to identify patterns and distinguish between the normal and the abnormal. Epidemiology is a key tool, but careful observation and logical deduction are also important. If handled correctly, even the most complicated disease outbreak situations can become excellent practice builders for the bovine practitioner.
We present the basic steps that we have found necessary to ensure success in an investigation of disease problems in the beef herd. We place emphasis in this particular presentation, though, on one of the main tasks of the investigation, which is to clearly define the problem as early as possible. This is because, to paraphrase some well-placed advice, a problem well-defined is three-quarters of the solution.

Cow Flow Through the Dairy
Authors: Lehenbauer Terry W. 
Published: March 2023

Dairy cow culling decisions have an important influence on the financial success of the dairy. Culling decisions can function as a component of genetic improvement and selection programs designed for long term gain and improved production efficiency. At the same time, culling may also represent failure or limited success of production medicine programs due to cows leaving the herd prematurely because of disease or health-related problems.
Culling decisions are important from several different perspectives. Costs for replacement heifers may represent up to 20% of the dairy budget.13 Negative cash flows occur when a cow is sold as non-fed beef and a heifer is added to the lactating herd as a replacement. Cows retained in the herd represent capital investments, which are subject to various forms of risk that may alter the earnings from those investments. Perhaps wrong decisions are being made regarding which cows to keep, and choosing different cows for culling might increase profits. The perceived importance of culling decisions is also demonstrated by the observation that owners of particularly large herds, who otherwise are not involved in making individual cow management decisions, often directly participate in the routine decision-making process for selecting cows to cull.
Annual culling rates for dairy herds in the US range from less than 25% to more than 35%, with 30% being average.2 Cows have different risks of being culled depending on their age.1,13 Although there is a tendency for increased culling rates with advancing age, management constraints and biases can modify this relationship. The typical cow remains in the milking herd less than 4 years13 even though peak milk production related to maturity ordinarily does not decline until 8 or 9 years of age for most cows.31 The reluctance of some producers to cull first calf heifers and choosing instead to give them a second chance is an example of management bias affecting culling policy.

Self-Perceived Sources of Stress and Burnout Determinants in Dentistry - A Systematic Review
Authors: Avramova Nadya 
Published: March 2023

Introduction. In recent decades, under the influence of various factors, there has been a serious increase in psycho-emotional tension and stress. Furthermore, considering unprecedented times of global pandemic threat, stress levels can rise significantly. Dental profession is physically and mentally stressful as dentists encounter a number of occupational hazards of a biological, chemical, physical, and psycho-emotional nature.
Objective. The current review paper aimed to answer the question: what are the most important stressors and burnout determinants in daily dental practice?
Materials and Methods. The Web of Science Core Collection database was searched for according to the PRISMA guidelines in September 2022. Empirical studies - observational, experimental, cross-sectional, and longitudinal studies published in English were considered for inclusion.
Results. The initial search yielded 355 articles. Eighteen studies met inclusion criteria and were considered for the final analysis. Two articles reported identical data; therefore, they were not included in the current report. Finally, this review presented 16 reports with a total of 8, 824 subjects.
Conclusions. Both long-term and short-term stress can cause negative effects on practitioner’s physical, mental, and emotional functioning. As healthcare providers, dentists should be aware of these risk factors, as well as they need to be sufficiently motivated to know the risks and inconveniences of their profession, learning effective strategies how to deal with adverse conditions, factors, and relationships. Providing information on this issue will contribute to increasing dentists’ awareness and improving their personal and professional performance.

Published: March 2023

Perkembangan sistem ketenagalistrikan semakin pesat sejalan dengan pengembangan energi baru terbarukan. Intermittent menjadi masalah utama pembangkit listrik terbarukan, sehingga penggunaan baterai menjadi solusi. Namun hal ini justru menghasilkan limbah bahan beracun dan berbahaya sehingga tujuan untuk menciptakan energi bersih tidak dapat tercapai. Pengembangan photovoltaic (PV) dengan sistem grid tied dapat menjadi solusi dari masalah tersebut. Manfaat dari penggunanaan PV dengan sistem grid tied adalah konsumen dapat menyuplai daya di kondisi daya berlebih dan digantikan pada malam hari sehingga ada pemotongan dari pembayaran listrik setiap bulannya. Dengan begitu, teknologi penyimpanan tidak lagi digunakan pada sistem ini dan terjadi dampak posisitif dari sisi ekonomi pada konsumen. Penelitian ini menganalisis aliran daya sebelum dan sesudah penggunaan PV pada beban home area network dan menghitung dampak ekonomi pada konsumen setelah menyuplai listrik pada grid utiliti.
