Abstract The use of agricultural pesticides is very important in improving production, but the residue of these pesticides on crops have a serious health effect on humans. On the other hand, there is another type of pollutants resulting from the use of veterinary medicines, as well as heavy metals and mycotoxins that also result in health risks to humans due to their consumption of milk and dairy products. Milk is an important and necessary food for the body as it is consumed daily by many people because its contain fat, protein, vitamin, and minerals. In this work, we present a review of most scientific articles from 1964 until 2020, related to evaluating milk contamination with various chemicals, especially pesticides and veterinary drugs. We observe from many research papers at different country in the world Lingering presence detectable values of chemical contaminate The maximum remainder, as a final result of this review paper we need to establish monitor program system for all chemical contaminate residue in milk and many food type to improve safety and reduce the risk for consumers in Iraq.

The association between the division of labour and worker body size of ants is typical for species that maintain physical castes. Some studies showed that this phenomenon can be also observed in the absence of distinct morphological subcastes among workers. However, the general and consistent patterns in the size-based division of labour in monomorphic ants are largely unidentified. In this study, we performed a field experiment to investigate the link between worker body size and the division of labour of the ant Lasius niger (Linnaeus, 1758), which displays limited worker size variation. We demonstrated that the body size of workers exploring tuna baits is slightly but significantly smaller than the size of workers located in the upper parts of the nest. Comparing the present results with existing studies, large workers do not seem to be dedicated to work outside the nest. We suggest that monomorphic workers of certain body sizes are flexible in the choice of task they perform, and food type may be the important determinant of this choice.

Heavy metal toxicity over the years has been proven to be a source of diverse health risks. Thou these metals, play certain biological roles, they are in excess amount get accumulated in the body and food chain displaying a chronic effect in the long run. Lead toxicity is an important environmental disease and its effects on the human body are devastating with its toxicity dependent upon the absorbed dose, the route of exposure as well as the duration of exposure. There is almost no function in the human body which is not affected by lead toxicity. Lead is highly persistent in the environment and because of its continuous use, its levels rise in almost every country particularly in developing countries like Nigeria where it occupies unique physical and chemical properties that make it suitable for a large number of applications. Various public health measures have been undertaken to control, prevent and treat lead toxicity occurring at various levels, such as occupational exposure, accidents and environmental factors. This article reviews the works listed in scientific literatures with recent updates regarding the toxicity of lead. Focus is also on the biomarkers of lead toxicity on the renal, hematological and oxidative stress conditions.

Pig farming currently occupies a prominent place in the southern states of the Brazil, owning approximately 50% of the national squad, estimated at 42 million pig heads. However, the swine activity contributes significantly to the generation of environmental impacts on the environment. Recently, the greatest need for animal protein has exerted pressures on the current animal production system and one of the alternatives has been to the use of veterinary medicines, which have several uses ranging from therapeutic use, preventive in the treatment of various diseases and as growth promoters. Its indiscriminate and uncontrolled use is currently endangering the environmental balance of producing sites through effluent contamination. Many producers have been using contaminated slurry as a biofertilizer. In this sense, further studies on techniques and processes of treatment of organic effluents contaminated by veterinary drugs are necessary. Alternative low-cost and environmentally viable treatment systems are needs to minimize the entry into the environment of these contaminants. Therefore, the composting process that can defined as a process of aerobic microbial decomposition of organic matter and nutrient recycling can be an alternative for the treatment of effluents contaminated by veterinary drugs.

Background: Puberty is a time when many changes occur in the body of a young person. It is also the time when nutritional habits are developed or modified. Healthy dietary choices are of particular importance for normal development during adolescence and are also predictive of future health. Aim of the study: The aim of this study was to assess the nutritional habits of junior high school students from the Kłomnice district with a focus on obesity. Material and methods: The study was carried out using 280 randomly selected secondary school students attending schools in Kłomnice, Częstochowa in the Silesian province. The research was carried out using a questionnaire comprising questions about gender, age, weight and height of the body and nutritional habits. Results: The nutritional habits of high school students from the Kłomnice district were evaluated to be low. Girls more frequently than boys had developed improper eating habits. Irregularities in the diet of the surveyed high school children are: incorrect number of meals a day, irregular food consumption, snacking between meals, adding too much sugar to hot beverages, infrequent consumption of milk and dairy products, coarse grains, vegetables, fruits and legumes and a high frequency of meat and sweets consumption. The nutritional habits of junior high school students from Kłomnice were at a sufficient level. Girls more often than the boys showed improper eating habits. Irregularities in the diet of the students in the study were: improper amount of food consumed during the day, irregular food consumption, snacking between meals, adding too much sugar to hot beverages, infrequent consumption of milk and dairy products, coarse grains, fish, vegetables, fruits and legumes and a high frequency of meat and sweets consumption. Conclusions: It is recommended that continuous nutritional education of children and adolescents is implemented in order to improve diet and thereby reduce the risk of obesity in the future.

Functional foods and nutraceuticals demand during the Covid-19 pandemic are increasing tremendously. This is showed that there is a shifting food consumption pattern into healthier food rather than only to satisfy hunger. Functional foods are foods that offer health benefits beyond their nutritional value, whereas nutraceuticals are commodities derived from foods, but are used in the medicinal form of pills, capsules, or liquids that demonstrated physiological benefits. Nutraceutical products consist of isolated bioactive substances such as vitamins, minerals, amino acids, and fatty acids as well as dietary supplements such as probiotics, prebiotics, antioxidants, and enzymes. As the second-largest country with the highest biodiversity, Indonesia has some natural resources that could be developed as functional food or nutraceutical ingredients such as ginger, cinnamon, lemongrass, honey, Moringa oleifera leaves, etc. Indonesian society has indigenous knowledge of the health effect of any plants and spices such as the health effect of “jamu”, a functional drink made from several parts of plants. However, the development of functional foods and nutraceuticals in Indonesia has so many challenges concerning regulation. The National Agency for Drug and Food Control of Indonesia did not regulate functional foods and nutraceuticals. However, they have some regulations about processed food with the claim, supplements, natural herbal, and food for medicinal uses. Hence, functional foods and nutraceuticals producers must adjust to the existing regulation. The research and development of functional foods and nutraceuticals consist of several steps namely identification of bioactive compounds, assessment of physiological effect, product formulation and processing, and clinical trial to meet the regulatory demand. The research activities will provide scientific evidence to prove food and nutraceutical functionality. Market demands are also important to obtain an innovative product that meets the consumer’s demand. Recent methods to develop functional foods and nutraceutical are “design thinking” methods, a method that focuses problem solving on human rather than on technology or organization. The typical design thinking protocol consists of 3 steps namely observation and synthesis, visualization and rapid prototyping, as well as revising and refining. In the first step, nutraceutical developers must understand the characteristic of targeted consumers. In the second step, models or sketches as well as the early version prototypes need to be created. Gathering feedback on the strengths and weaknesses of the product will lead to the necessary corrections before product commercialization. In the third step, a team from many different backgrounds and specializations can be involved to revise and refine the new product. A Penta helix collaboration between academia, industry, citizen, public authorities, and non-government organization (NGO) can be used as a model of networking in functional foods and nutraceuticals development. The use of “design thinking” methods will minimize the risk of product failure in the market. One of our experiences in functional food development is the exploration of glucomannan from Porang tubers (Amorphophalus oncophylus) as a functional ingredient. Glucomannan, a water-soluble fiber that can be fermented, is extracted from Konjac (Amorphophallus konjac) tuber or root. However, in Indonesia glucomannan can be extracted from Porang tuber that can be found in many areas. In the beginning, we collaborate with the local farmer, NGO, and governments to optimize the production of Porang tubers. After we found the method to extract the glucomannan, we develop several food products namely jelly, noodle, rice analog, etc and analyze the physical, chemical, microbiological, and sensory characteristics. The jelly product containing glucomannan was tested for the clinical trial. We found that this jelly could lower the body weight and body mass index of the overweight and obese subjects as well as maintain the level of blood glucose, the total cholesterol, LDL cholesterol, and triglycerides. The health benefit of this jelly can be used as the rationale for health claimed. It is important to collaborate with the food industry to commercialize this product. In conclusion, Indonesia needs to develop guidelines for Functional Food and Nutraceuticals Development, this guideline can be used as a reference for producers for claims on nutrition and health. For researchers, academia, and the food industry that will develop a new functional food and nutraceutical product, it is important to plan and know the targeted consumer so that the new product will succeed in the market.

Human economic activity leads to the accumulation of anthropogenic contaminants in food. The aim of the study was to analyze the public health risk associated with the oral intake of organochlorine pesticides (HCH, DDT), which are widely used in agriculture. The risk assessment was carried out taking into account data on the actual nutrition of 1798 people (823 men and 975 women) aged 18 to 65 years using the Nutri-prof software package. To assess the contamination of food with organochlorine pesticides, 16510 samples of various food groups were analyzed. The greatest non-carcinogenic risk due to the intake of HCH into the body with food is due to the consumption of bread and bread products, vegetables and melons, potatoes, milk and dairy products; meat and meat products, milk and dairy products. The highest level of total individual carcinogenic risk for DDT and HCH, taking into account the median concentration, corresponds to the third range and is acceptable for professional groups. The excess of the background risk values for the endocrine system in the consumption of bread and bakery products occurs at the age of 45, the transition from a negligible level of risk to a level of moderate risk occurs at the age of 65. The results obtained indicate the effectiveness of the system of sanitary and epidemiological surveillance over food safety, the methodological approach to risk assessment under consideration allows making timely management decisions, taking into account the nature of work and nutritional characteristics.

The article gives an overview of modern opinions about the ways of possible contamination of milk and dairy products by mycotoxyn. The key indicator of the presence of mycotoxins in milk  and dairy products is the level to which micromycetes affect productive livestock’s feed. Yet, mycromycetes and mycotoxines do not always occur together: some test samples can contain certain micromycetes, but no mycotoxines. Mycotoxines are synthesised by micromycetes only under certain favourable conditions. The multi-chambered stomach ecosystem of lactating cows utilises most mycotoxins occurring in food. Only a small amount of those is excreted in milk. However, some mycotoxins can bind to milk caseins. In this case, cheese and other dairy products can contain far higher amounts of mycotoxins than at  the initial stage of milk production. The paper compares the maximum permissible levels of mycotoxins in milk and in dairy products  according to the regulations of Ukraine and the EU. It presents the mycotoxins isolated from secretions of mammary glands of humans and productive animals, and describes their effect on the body’s physiology. It also provides a structural diagram of how mycotoxins contaminate milk and dairy products following the path “Animal feed – dairy products.” We suggest four-stage assessment of the risks of mycotoxin contamination of milk and dairy products: Stage I – identifying the producer of mycotoxin (molecule, metabolites in feed, milk, and dairy products). Anamnesis; Stage II – constructing a sequence diagram. Inspecting all production stages to identify the main ways  and periods of contamination, determining and describing the symptoms of contamination; Stage III – assessing how the intensity and duration of exposure to a mycotoxin and its metabolites are likely to effect on the body. Modelling the influence of mycotoxins on the body; Stage IV – assessing the risk and determining measures to eliminate or minimise it. Risk scenario forecast

Abstract In line with the general aims of scientific textuality, research papers in the biomedical and psychiatric academic domains mostly attempt to demonstrate the validity of their assumptions and to contrast with the sense of uncertainty that sometimes frames their conclusions. Moving from this premise, the present paper aimed to focus on these features and to investigate if and the extent to which biomedical and psychiatric texts convey different social-epistemic rhetoric of uncertainty. In view of this, a qualitative study was conducted adopting diatextual analysis to investigate a corpus of 298 scientific articles taken from the British Medical Journal and from the British Journal of Psychiatry published in 2013. Our analytical approach led to identifying two different types of social-epistemic rhetoric. The first one was mostly oriented to “describing” the world, accounting for the body-mind nexus as conceptualized within the “medical” point of view. On the other hand, the second one was oriented to “interpreting” the world, debating the problematic and critical features of the body-mind relationship as developed within the psychiatry discursive realm.

Постановка задачи. Работа посвящена изучению оценочных характеристик отзыва научного руководителя, функционирующего в рамках академического дискурса. Впервые выявляются оценочные стратегии и тактики научного руководителя, вербализованные в отзыве при характеризации научно-исследовательской работы магистранта и бакалавра. Результаты. Как показало исследование, посредством оценочных значений, которые выстраивают отзыв о работе выпускника над выпускной квалификационной работой, научные руководители положительно характеризуют исследовательские навыки студентов. Отрицательные оценочные значения не вербализуются, но имплицируются в рекомендациях уделять внимание в дальнейшей работе, например, более планомерной организации исследования. Наиболее универсальной и распространённой характеристикой работы студента является формулировка академический дискурс сформирован , которая включает в себя все положительные оценочные значения, релевантные для научно-исследовательской деятельности в рамках академического дискурса. Во всех структурных элементах отзыва научные руководители прибегают к использованию оценочных значений. В наименьшей степени оценочные значения представлены в разделе Умение работать с научной, методической, справочной литературой и электронными информационными ресурсами. Выводы. Отзыв научного руководителя как жанр академического дискурса представляет собой амальгаму оценочных средств, с помощью которых научный руководитель эксплицирует, а в некоторых случаях и имплицирует своё отношение к проделанной студентом работе. В качестве объекта оценки служат те аспекты научно-исследовательской деятельности, которые выделены как структурные элементы отзыва, а также дополнительные объекты, которые научный руководитель считает необходимым выделить. В ходе исследования были выделены оценочные стратегии импликации, интенсификации, рекомендации и констатации. Problem Statement. The paper focuses on evaluative characteristics of research advisors’ reviews functioning in the framework of academic discourse. Evaluative strategies and tactics have been revealed for the first time as a part of a research advisor’s review. Results. The research has shown that research advisors characterize positively various aspects of graduate students’ research papers and the way they organized their research work. Negative evaluations are not verbalized, but teachers implicitly mention that their students should organize their work more thoroughly in the future. The fact that academic discourse has been acquired by the student to the full extent serves as a positive characteristic of their work, and, therefore, includes all the evaluations relevant for doing a research and for research results. In all the structural elements of the reviews research advisors use a variety of evaluative means. The latter are represented to a lesser extent in the structural element concerning the Ability of a student to retrieve information and to use a variety of information resources. Conclusion. Research advisor’s review as a genre of academic discourse is an amalgam of evaluative means which enable the research advisor to explicitly verbalize his attitude towards a student research work. Evaluative means characterize those aspects of research work which are specified in the body of the review as structural elements. Moreover, teachers specifies work ethic, ethical behavior, personal characteristics that are crucial for the research work. The research has revealed evaluative strategies of intensification, recommendation, stating and implication.

Abstract Sound and vibrations are often perceived via the auditory and tactile senses simultaneously, e.g., in a car or train. During a rock concert, the body vibrates with the rhythm of the music. Even in a concert hall or a church, sound can excite vibrations in the ground or seats. These vibrations might not be perceived separately because they integrate with the other sensory modalities into one multi-modal perception. This paper discusses the relation between sound and vibration for frequencies up to 1 kHz in an opera house and a church. Therefore, the transfer function between sound pressure and acceleration was measured at different exemplary listening positions. A dodecahedron loudspeaker on the stage was used as a sound source. Accelerometers on the ground, seat and arm rest measured the resulting vibrations. It was found that vibrations were excited over a broad frequency range via airborne sound. The transfer function was measured using various sound pressure levels. Thereby, no dependence on level was found. The acceleration level at the seat corresponds approximately to the sound pressure level and is independent of the receiver position. Stronger differences were measured for vibrations on the ground.
