Published: November 2021

Abstract
The defects formed in the manufacture of the vermicular graphite cast iron engine cylinder head seriously affect the operation of the engine, which is necessary to detect. Ultrasonic testing is a non-destructive testing method that has the advantages of quick response, high resolution, and high security. In this paper, various types of specimens are prepared corresponding to different types of actual defects in the vermicular iron cylinder head. An ultrasonic A-scan system was built to test the specimens. The short-time Fourier transform, the continuous wavelet transform, the empirical wavelet transform, and the empirical modal decomposition were adopted to transform the signals into spectrograms which were further analyzed to reveal the inherent features of defects. The results show that the short-time Fourier transform can be used to distinguish all the common defects comparing to other methods. Comparing to the time-domain waveforms, the transformed spectrograms provide clear time-frequency distribution and highlight the inherent characteristics of the signal.

Abstract
In order to study the process and characteristic of the fragments in the warhead with one end cap under full constraint condition, we established a cylindrical casing with two end caps which one of them was fully constrained using the simulation analysis. The result showed that the fragmentation of cylindrical casing with one end full constrained has its own characteristic. The Mach stem was generated when the detonation wave propagated to the fully constrained end cap under the condition of one end detonation, working on unreactive explosives and causing the nearby fragment subjected to nearly 2.5 times the normal pressure to obtain a higher speed. The cylindrical casing first ruptured at the contact surface with the fully constrained end, and then at the end cover of the initiating end, and then the rupture extends to the whole cylindrical casing. The detonation products started to leak out from the rupture. driving fragments to fly, and forming two dense flying areas. The analysis of this paper can provide a reference for the optimal design of this kind of warhead.

A Numerical Study on the Control of Horizontal Cracking at the Ends of BS22 Hollow-type PC-girders Utilizing Midas FEA
Authors: Karimi Abdul Khaliq , Aasim Bashir Ahmad , Tomiyama Jun 
Published: November 2021

AbstractWhen the prestressing forces transfer from PC-strands to concrete, a region of stress concentration develops at the ends of pretensioned girders, which often results in horizontal cracking during or just after the detensioning process. In this study, a hollow PC-girder was modeled utilizing a Finite Element Analysis software Midas FEA to identify the horizontal cracking locations in terms of the principal stresses at the end-zone of the hollow PC-girder. Strand-debonding and placing end-zone reinforcements were hired in this work by introducing four cases. The only strand-debonding method could not prevent horizontal end crack penetration. Though the end-zone reinforcements were placed alongside the strand-debonding, this combination could reduce principal stresses to a level that could bring the crack size to a negligible range.

Abstract
The goal of this study was to investigate the influence of reducing sodium chloride content in chicken ćevapčići (kebabs) by partial replacement of sodium chloride with potassium chloride and ammonium chloride, with the target of achieving the optimal salty taste. The trial consisted of five groups. In the control group of chicken ćevapčići, only sodium chloride was added. In group 1, one third of sodium chloride was replaced with potassium chloride; in group 2 one half of the sodium chloride was replaced with potassium chloride; in group 3, one third of sodium chloride was replaced with ammonium chloride. In group 4, sodium chloride was half reduced and one quarter of ammonium chloride in the relation to control group was added. Sensory evaluation was performed by ten trained assessors using numeric scales. Evaluations of colour acceptability and consistency showed there were no statistical differences (P>0.05) between the ćevapčići. The most expressed saltiness was evaluated in the control ćevapčići group due to it having the largest amount of added sodium chloride, as well in group 3 ćevapčići, wherein one third of the sodium chloride was replaced with ammonium chloride.
Arugula and pre-converted arugula extract as natural Nitrate/Nitrite sources for heat-treated sausages

Published: November 2021

AbstractThe aim of this study was to investigate using arugula or pre-converted extracts as nitrite alternatives in heat-treated fermented sausages. Sausages with nitrite, 150 mg/kg of NaNO2, 1.2% arugula extract, and 1.5% pre-converted arugula extract were formulated. Natural nitrate sources added resulted in significantly lower oxidation content compared to negative control groups at initial storage. The addition of natural nitrate sources influenced colour, pigments, and conversion rate of sausages. Pre-converted arugula extract showed little effect on the residual nitrite content. The result of colour, oxidation, and nitrite analysis suggest pre-converted arugula is a potential nitrite replacer, but arugula as a nitrate source is limited to provide the functions of nitrite.
Biofilms in the food industry – impact on human health
Authors: Cirkovic I 
Published: November 2021

Abstract
Biofilms are complex microbial communities formed by one and more species embedded in an extracellular polymeric matrix of different compositions depending on the attached microbial species and the type of food manufacturing. Attachment of bacteria to food contact surfaces and the subsequent formation of biofilms can cause equipment damage, food spoilage and even human diseases. Foodborne diseases associated with biofilms in the food industry can be intoxications or infections and can have great impact on human health. Foodborne pathogens that express capacity for biofilm formation under different conditions in the food industry, and that are in the scope of our investigations, are Salmonella (which, on contaminating a food pipeline biofilm, could induce massive outbreaks and even death in children and elderly) and Listeria monocytogenes (a ubiquitous bacterium that can cause abortion in pregnant women and other serious complications in children and the elderly).

Abstract
Poultry meat production is one of the most dynamic sectors in agriculture, recording the quickest growth in the food industry, while egg production has shown strong growth in the last twenty years. Combined with meat production, it is achieving the highest growth when it comes to meeting protein needs for the global population. In economic terms, coccidiosis is one of the most significant poultry diseases. Effective application of coccidiostats in poultry feed has been playing a key role in development of commercial poultry production for more than 50 years. The aim of this research was to estimate occurrence and residue concentrations of coccidiostats in table eggs, poultry liver and meat, available on the market in Bosnia and Herzegovina (B&H). Residues of lasalocid were found in table eggs, while residues of nicarbazin, maduramicin and diclazuril were detected in broiler meat and liver.
Meat quality of poultry fed with diets supplemented with insects: A review
Authors: Dalle Zotte Antonella 
Published: November 2021

AbstractThe development of sustainable feed ingredients for monogastric livestock is now also considering insect products. Although the regulation on the use of insect products differs among countries, resulting in restrictions on use in poultry diets, global research is exploring all the strengths and weaknesses of their inclusion. The scientific literature has extensively studied the relationship between insect-containing diet and effects onante-mortemfactors in fish and poultry, however the relationship between insect-containing diet and meat quality has only recently been considered. This review aims to collect the results of the studies that have related the dietary use of some insect species, such as the black soldier fly (Hermetia illucens), the yellow mealworm (Tenebrio molitor) and the silkworm (Bombyx mori), on the physicochemical and sensory traits of poultry meat. The insect source in poultry diets rarely changed the related physicochemical variables or the sensory profile of the meat, whereas the fatty acid (FA) profile was the variable that was most affected, and inclusion of black soldier fly always resulted in meats with a more saturated FA profile, yellow mealworm in a more monounsaturated FA profile, whereas silkworm produced meat with a more unsaturated FA profile, rich in valuable omega-3 FA.
The possibilities of alternative protein use in animal nutrition
Authors: Djuragic O , Rakita S , Dragojlovic D 
Published: November 2021

Abstract
The Food and Agriculture Organization (FAO) predicts there will not be enough food for human and animal nutrition until 2050. Global demand for animal protein for human consumption is increasing, and this consequently increases the price of these ingredients. This will open several challenges to provide enough animal feed. In the European Union, the use of processed animal proteins in pig and poultry diets is prohibited due to the bovine spongiform encephalopathy (BSE) legislation, while globally, the land availability for soy cultivation is limited. The European food market is dependent on huge import of soybean, which is the main source of valuable proteins and one of the main ingredients in feeds. Feed ingredients must not contain antinutritive factors that would adversely affect animal production and must have an acceptable price. Some of the alternative plant sources of protein are fava beans, peas, lentils, hemp, different grain seeds, etc. To find alternative sources of protein of animal origin scientists are increasingly investigating the use of worm, snail or grasshopper meals and also marine organisms, usually algae, shells or starfish. Single cell proteins are a specific kind of protein from different microbial sources, including microalgae, yeast, fungi, and bacteria.

Published: November 2021

Abstract
Abstract Pesticide residues in or on foods of plant/animal origin occur as a result of the use of chemical agents in plant protection, biocide preparations and veterinary medicine and may pose a risk to public health. For this reason, a comprehensive legal framework has been adopted in Bosnia and Herzegovina, defining rules for the approval of active substances used in plant protection products, the use of plant protection products and the regulation of maximum permitted quantities of pesticide residues in and on food. In 2019, 195 samples were analysed as part of pesticide monitoring. The control programme carried out the monitoring of residues/remains of 180 active substances in 155 products of plant origin, 30 products of animal origin and 10 products from the category of food for infants and young children. In total, of the 195 samples analysed, 141 samples did not contain pesticide residues at the quantification level, but 54 samples (27.7%) contained pesticide residues in/above the quantification level.

Published: November 2021

AbstractFoodborne diseases encompass a wide spectrum of illnesses and are a growing public health problem worldwide. They are caused by consumption of food or water contaminated by pathogenic (disease-causing) microorganisms such as bacteria, viruses and parasites. The contamination of food can occur at any stage in the process from food production to consumption (“farm to fork”) and can result from environmental contamination (water, soil or air). They enter the body through the gastrointestinal tract where the first symptoms often occur like nausea, vomiting, stomach cramps, and diarrhoea. However, symptoms differ among the different types of foodborne diseases and the patient’s immune status. Symptoms can sometimes be severe and some foodborne illnesses can even be fatal. Commonly recognized foodborne infections are: campylobacteriosis,Escherichia coliO157:H7 infection and haemolytic uremic syndrome (HUS), salmonellosis, cryptosporidiosis, listeriosis, giardiasis. norovirus infection, scombroid fish poisoning, shigellosis, toxoplasmosis,Vibrioinfection and yersiniosis. One of the top three germs that cause illnesses from food eaten in EU isSalmonella.

Published: November 2021

Abstract
In recent times, food is not only observed from the point of view of the required intake for growth, development and regeneration of the body, but also has a leading role in the quality of human life. Therefore, the diet focuses on optimizing the daily intake of both nutrients and non-nutritive ingredients of food, all in order to preserve health and, above all, reduce the risk of chronic non-communicable diseases. Functional food can be considered food that has been scientifically proven to have a positive effect on certain body functions (in addition to the usual nutritional value) that contribute to human health and reduce the risk of disease. At the same time, it is important that the food has a standard form and that the positive effect on health is manifested by consuming the usual amount of food. The functionality of food is achieved by the presence in it of bioactive components (one or more) which have been scientifically proven to have positive effects on human health in the quantities in which they are present in food. The nutritional value of foods of animal origin depends on many factors, but certainly animal diet has the greatest impact. In human nutrition the so-called designed products of animal origin (meat, milk, eggs) are used, which are due to the specific animal diets enriched with n-3 fatty acids, vitamins, carotenoids or trace elements. Today, there are nutritional strategies by which we can access functional foods for the purpose of health promotion.

Abstract
The aim of this study was to assess the dietary exposure of phosphorus in the Serbian adult population by combining individual consumption data with available data for analysed meat products. During a three years period of investigation (2018 to 2020), a total of 682 samples consisting of 425 cooked sausages and 257 smoked meat products were collected from different local retail markets across the Serbia to examine phosphorus concentrations. The mean phosphorus concentration, expressed as P2O5, varied from 4.68±0.88 g/kg to 6.05±1.30 g/kg in finely minced cooked sausages and smoked meat products, respectively. The average estimated daily dietary intake (exposure) (EDI) of phosphorus ranged from 1.115 mg/kg BW (body weight)/day (finely minced cooked sausages) to 1.441 mg/kg BW/day (smoked meat products). Phosphorus dietary intake (exposure) averaged 3.08% of the acceptable daily intake (ADI: 40 mg/kg BW/day). According to our results, the average phosphorus exposure in the Serbian adult population from consumption of these meat products is far below the European ADI.

Published: November 2021

Abstract
The aim of this study was to determine the microbiological, sensory and chemical changes of modified atmosphere packaged ćevapčići in a gas mixture consisting of 70% O2 and 30% CO2. Packaged ćevapčići were stored for 10 days at 3ºC. Microbiological examination comprised determination of pathogenic microorganisms (Salmonella spp., coagulase positive staphylococci, Escherichia coli and Listeria monocytogenes) as well as indicators of hygiene and spoilage (total viable count, psychrotrophic bacteria, Enterobacteriaceae, lactic acid bacteria and Brochothrix thermosphacta). Using quantitative-descriptive test with grading scales from one to five, sensory properties of ćevapčići were assessed (color and odor in raw condition and odor, texture and taste after roasting) on the 1st, 4th, 6th, 8th and 10th days of storage. Regarding the chemical parameters, every day during the storage, pH was examined and on 4th and 8th days, acid value and peroxide number were established. On the basis of the results obtained and the recommended total viable count, which should not be higher than 7 log cfu/g, and taking into consideration sensory properties, we can conclude that ćevapčići packed in the modified atmosphere containing 70 % O2 and 30% CO2 had a shelf life of seven days.

Published: November 2021

Abstract
Increase in growth rate through genetic selection and improved nutrition in broiler chickens has been associated with high body fat deposition. This is particularly evident under ad libitum feeding that is normally practiced. Excessive fat deposition in the body of broilers is a common problem for poultry producers and consumers. Studies have shown that feed restriction could decrease fat content and increase protein deposition in carcasses, thus resulting in their improved composition. In addition to determining the optimal time to start and the duration of the restrictive nutrition, the success of the given programs largely depends on the intensity of the restriction, as well as the type of applied technique. Considering that in a large number of studies, the application of restrictive programs resulted in a reduction of body fat in broilers, but at the same time the desired body weight was not achieved at the slaughter (market) age, these programs should not be a priori rejected as ineffective. It is necessary to determine whether the market price of the obtained product (poultry meat) with its reduced fat content justifies the lower body weight of broilers achieved at the end of the fattening period.

Abstract
Many wild animal populations are considered endangered due to anthropogenic activities. Wildlife and nature habitat preservation requires holistic and science based approaches supported by adequate regulations. One of the means for wildlife preservation is undoubtedly heath monitoring and investigation of infectious diseases of the wild animal populations, particularly if spillover effects are considered. Even though the theoretical background is well researched, implementation of disease prevention and control measures in wildlife populations entails more challenges than in domestic animal populations. Immediate signs of health disorders in wildlife often become evident when the infectious agent is well established in an area. Additionally, due to unrestricted and often long-range movement of wildlife, diseases are easily spread across borders. Brown bears, indigenous in Europe, are classified by EU regulations as endangered, almost extinct and rare. The wild bear population in Bosnia and Herzegovina shares a genetic lineage with bear populations of neighbouring Croatia, Serbia and Montenegro and is one of the few remaining fragments of bear populations in Europe. The aim of this paper is to describe implemented activities for health and telemetric monitoring of wild bears in the Nature Park Skakavac, Canton Sarajevo, Bosnia and Herzegovina.
