Published: May 2023

Due to the challenging dispersion of graphene in aqueous media, organic solvents are commonly used in conductive graphene inks. This will result in safety issues and environmental pollution. In this study, we demonstrated a green approach of graphene ink preparation through one-pot synthesis reaction that produce a hybrid reduced graphene oxide (rGO)-silver nanoparticles (AgNPs), with deionized water as solvent. The synthesized rGO-AgNPs was monitored using ultraviolet–visible (UV-Vis) spectroscopy and fourier transform infrared (FTIR). A stable dispersion of rGO-AgNPs ink was confirmed through UV-Vis analysis. FTIR result showed the removal and the reduction in the intensities of absorption bands of oxygen-containing functional groups, which indicated that graphene oxide (GO) has been successfully reduced to rGO in the hybrid ink. The printed film of rGO-AgNPs exhibited a high conductivity of 1.50 × 104 S/cm, proven that the electrical performance of the hybrid ink has been improved as compared to previously reported GO-based ink. Printed into interdigitated electrode (IDE), the impressive characteristic of our hybrid ink performed well as a high-sensitivity flexible humidity sensor.

Published: May 2023

Ti15Mo7Zr15Ta1.00Si titanium alloy contained higher concentration of silicon and better elastic properties, excellent biocompatibility and lower processing cost. To investigate the influence of texture shapes and parameters of joint surfaces on the friction and wear properties under bionic lubrication conditions, three types of texture morphologies (circular, elliptical, and equal-width grating) with the same pit depth and surface coating rate were processed on a Ti15Mo7Zr15Ta1.00Si titanium alloy using a picosecond laser processing system in this study. Then, the "ceramic–metal" friction and wear tests of textured and smooth samples under lubrication with bovine serum protein were performed using a UMT-3 multifunctional friction and wear testing machine. The results showed that the surface micro-texture morphology could improve the anti-friction properties of titanium alloy artificial joint materials. The wear resistance of the circular micro-dimples improved with an increase in the circular diameter. In the elliptical micro-dimple texture morphology, the vertical arrangement of the ellipses could provide the maximum bearing capacity and best friction reduction effect, followed by the elliptical morphology and the transverse ellipse arrangement. The denser the arrangement of the equal-width bars, the better the friction reduction effect was.

Authors: Arafa Dalia F. , Moawad Mohamed S.
Published: May 2023

Shear behavior of reinforced concrete beams using steel lathe scrap waste and end hooked steel fibers as fully or partially web shear reinforcement replacement was studied. Steel lathe scrap waste is generated from industrial steel waste and can be used as recycled fibers offering additional advantages towards environmental pollution reduction. To investigate their effect of reinforced concrete beam under shear behavior, ten reinforced concrete beam specimens with 1200 mm long, 200 mm wide, and 300 mm high were tested under quasi-static loading (two-point loading). The studied parameters in this investigation were types of fibers such as steel lathe waste fiber and traditional hooked steel fiber ratio and the web shear reinforcement ratio are zero% and 50%. Results observed were initial and post-cracking stiffness, maximum capacity load, vertical displacements, modes of failures, and the ductility of the specimens. It was concluded that using of steel lathe scrap waste and hooked steel fibers in concrete are advantageous, they changed the mode of failure of the beam from a brittle to a ductile mode of failure due to the ductility of steel used, whether traditional steel fiber or steel lathe waste fiber. The optimum ratio of the steel lathe scrap waste was found equal 0.5% while the optimum ratio of traditional hooked steel fiber is 1% as fractional volume.

Published: May 2023

Desiccation is the process of extreme drying that results in cracking in materials such as soils. Cracking is a complex process that has the potential to spread and penetrate deeper into the soil, which could lead to instability in earth structures like embankments. A number of desiccation tests were conducted to observe the crack behaviour of manufactured kaolin clay at laboratory scale. All samples were prepared at variation of initial water content and desiccation tests carried out using aluminium desiccation trays. Their crack behaviour was monitored at different thickness and comparison made to the samples tested on different base materials such as ceramic, steel and wood plates. The drying process, crack propagation and pattern were measured and observed daily. A digital image is captured and the crack intensity factor (CIF) calculated manually using a grid system. It was found that a sample of kaolin clay that was 5 mm thick had the highest CIF with rapid propagation and produced non-orthogonal patterns. It also discovered that the thickness of the samples, type of plates utilised and soil state at the start of the test have an impact on the formation and propagation of cracks.

Authors: Li Xiao Song , Liao Rui , Zhong Wu Yong
Published: May 2023

The effects of modification, electromagnetic stirring and compound treatment (modification and electromagnetic stirring) on the microstructure and thermal stability of Al-13% Si alloy are experimentally investigated. The results show that the three melt treatments can change the microstructure of the alloy. The modification has obvious refining effect on primary silicon and eutectic silicon grains, electromagnetic stirring has refining effect on primary silicon grains, and eutectic silicon grains appear coarsening phenomenon. The latent heat is obviously decreased by electromagnetic stirring, while the latent heat is increased by modification. Refining eutectic silicon grains will increase the latent heat of phase transformation of the alloy. When 560 °C remains unchanged, the melting temperature of the alloy generally decreases with the increase of holding time, but fluctuates, with a decrease of 7 °C. The latent heat decreases with the increase of constant temperature time, and the decrease amplitude reaches 8.4%.

Published: May 2023

This paper presents the regression model for predicting the maximum dry density (MDD) and optimum moisture content (OMC) for sedimentary residual soil mixed with bentonite. The empirical models were developed in accordance with the statistical validity steps and conditions. The laboratories were conducted to determine the physical properties of mixed samples with bentonite such as Atterberg limit and particle size distribution. Meanwhile the compaction testing was performed on the mixed soil samples with bentonite to determine the MDD and OMC values at different compaction energies. The data obtained from laboratories and secondary data were used to develop an empirical model. The results showed there is significant relationship between the particle size, compaction energy and bentonite content to the OMC. Meanwhile there is a relationship between the OMC, bentonite content and compaction energy to the MDD. Reasonably good regression coefficients are obtained in case of both model which R2 = 82% for MDD model and R2 = 72% for OMC model. Meanwhile the determination coefficient and mean square error (MSE) for validated model between predicted model and empirical model were given R2 = 89.5% with MSE = 0.065% for MDD model and R2 = 79.5% with MSE = 5.9% for OMC model. Therefore, the models developed present a good predicting for MDD and OMC values.

Lithium nickel cobalt manganese oxide, LiNi1/3Co1/3Mn1/3O2 (NMC 333) become a promising cathode material and attracted much attention to replace the LiCoO2. The structure, particle size, and morphology are some of the factors that influence the performance of the NMC 333 materials were study in this work. The synthesis method of doped NMC 333 materials was done via combustion method and citric acid was used as a fuel. The final products of LiNi0.3Mn0.3Co0.3Al0.1O2 and LiNi0.3Mn0.3Co0.3Al0.05Ti0.05O2 were denoted as 333A and 333AT, respectively. Based on the XRD results, all materials showed a pure, single phase and isostructural with hexagonal α-NaFeO2. 333AT material show good cation ordering with RIR value of 1.25. It also shows the higher (003) peak intensity and smaller full widths at half maximum (FWHM) indicate this material has higher structural crystallinity and smaller crystallite size than 333A. Meanwhile, FESEM results revealed that all materials have morphology of polyhedral like shape and well-crystallized particles with smooth surfaces. Both materials clearly made up of micro-sized particles with the range particle size from 103 nm to 975 nm. 333A material display slightly larger crystallite size compared to the 333AT material. As a conclusion, doping technique will effect the structural and the morphology of materials.

Published: May 2023

Inkjet printing is a promising technique for fabricating printed electronics. This technique acquires the utilization of conductive ink to form a fine and thin resolution conductive structure on a flexible substrate. The challenges are to design a stable conductive ink with a controlled properties to prevent nozzle clogging. Furthermore, a fine structure construction often demonstrated poor device performance due low mechanical durability. In this work, we have characterized morphology of the newly developed inkjet-printable nanosilver conductive ink (Mi-Ag) in our laboratory. The ink shows a stable colloidal ink zeta potential of-79.1 mV with nanoparticle size less than 100 nm properties has been tailored for compatibility with inkjet printing of conductive pattern on polyethylene terephthalate (PET) flexible substrate. It has been ascertained that the flexible electronic form factor affects the quality of the physical and electrical properties of printed pattern and the device performance. Hence, the bending test of the printed RFID patterns fabricated with different layer of thicknesses was investigated. Electrical properties of the samples were monitored by in-situ conductivity and resistivity measurement under cyclic bending testing. Pattern with thinnest layer of 1.31μm (1X) had the smallest electrical properties percentage drop (38.4%) at 12,000 bending cycles due to the fact that in thick layer, the interparticle network started to change during bending and became weaker due to the large amount of the particles in the dense printed layer. In contrast, printed device exhibited minimal increase in resistivity. Consequently the particle gap increased which allowed the movement of electrons, leading to the increased of electrical resistance. The device endurance characteristic is crucial to satisfy future design requirement of flexible electronic applications.

In this paper, the modeling of SJ-MOSFETs beyond the voltage class of 3.3 kV simulated with verified deep aluminum box-like shaped profiles by using TCAD simulation is described. The simulation results are used to investigate the influence of ion implantation parameters on electrical characteristics. For the formation of pillar regions, high energy implantation is performed through energy filter with a multi epitaxial growth method using a patterned mask. While high thickness of epitaxial layer is indispensable for obtaining a high blocking capability, it is revealed that the optimization of doping concentration of p-pillar and drift layer parameters yields similar on-state-resistance by charge compensations of SJ-structure.

Previous work from our group and others has shown that patients with breast cancer can generate a T cell response against specific human epidermal growth factor 2 (HER2) epitopes. In addition, preclinical work has shown that this T cell response can be augmented by Ag-directed mAb therapy. This study evaluated the activity and safety of a combination of dendritic cell (DC) vaccination given with mAb and cytotoxic therapy. We performed a phase I/II study using autologous DCs pulsed with two different HER2 peptides given with trastuzumab and vinorelbine to a study cohort of patients with HER2-overexpressing and a second with HER2 nonoverexpressing metastatic breast cancer. Seventeen patients with HER2-overexpressing and seven with nonoverexpressing disease were treated. Treatment was well tolerated, with one patient removed from therapy because of toxicity and no deaths. Forty-six percent of patients had stable disease after therapy, with 4% achieving a partial response and no complete responses. Immune responses were generated in the majority of patients but did not correlate with clinical response. However, in one patient, who has survived >14 y since treatment in the trial, a robust immune response was demonstrated, with 25% of her T cells specific to one of the peptides in the vaccine at the peak of her response. These data suggest that autologous DC vaccination when given with anti-HER2–directed mAb therapy and vinorelbine is safe and can induce immune responses, including significant T cell clonal expansion, in a subset of patients.
Squaloraja Riley 1833 (Holocephala: Squalorajidae) from the Lower Jurassic of Osteno Konservat-Lagerstätte (Como, NW Italy)
Authors: Duffin Christopher J. , Garassino Alessandro , Pasini Giovanni
Published: May 2023

A remarkable, complete specimen of a squalorajid holocephalian is described for the first time from the Lower Jurassic (lower Sinemurian) rocks of Osteno (Como, NW Italy). It is the only such specimen known from the locality and belongs to a (possibly juvenile) female. The Italian specimen is assigned to Squaloraja sp., and has a large dorsoventrally flattened head, long rostrum, a single mandibular tooth plate on each lower jaw, a well-developed synarcual, thick notochordal sheath calcifications, and only slightly reduced squamation comprising distinctive placoid scales with stellate bases. There is no ethmoid canal, dorsal fin or fin spine. The Lower Jurassic succession (‘Lower Lias’) of Lyme Regis (Dorset, UK) has yielded only two incomplete purported female specimens of the type species of the genus, Squaloraja polyspondyla, thus restricting potential comparison with the Italian specimen. This new record of the genus expands the known palaeogeographical distribution of this rare holocephalian.

Background and objective

Biodegradable polymers, such as polyhydroxyalkanoate (PHAs), have recently been recognized as polyesters owing to their properties as biodegradable thermoplastics.

Materials and methods

The main objective of this study was to isolate an efficient polyhydroxybutyrate (PHB) producer from soil collected from different rhizospheric areas in Egypt. The potent strain was identified using 16 s rRNA sequence analysis. Plackett–Burman and central composite sequential designs were used to investigate cultural variables influencing PHB production (central composite sequential design).

Results and conclusion

Of a total of nine different isolates, three were found to be PHB positive based on the color using Nile Red stain. The potent strain was identified as Bacillus safensis (NR_113945.1). Using one factor at a time experiments, sugar molasses and ammonium sulfate, respectively, were the best carbon and nitrogen sources, whereas the best inoculum was 10 ml/100 ml of fermentation medium. Cultural variables influencing PHB production were studied using Plackett–Burman and central composite sequential designs. Accordingly, the most influential factors on PHB production were sugarcane concentration, inoculum size, and KH2PO4. Under the optimized conditions, a PHB content (93% cell dry weight) of 1.17 folds was attained. Furthermore, the Fourier transform infrared spectroscopy and 1H-NMR results confirmed the produced polymer as PHB. These results give insight into the use of locally isolated bacteria (B. safensis (NR_113945.1) utilizing inexpensive substrate such as sugarcane molasses for PHB production.

Piper guineense leaves were studied for their phytochemical, proximate, and mineral content.  Standard methods, such as elemental determination with an atomic absorption spectrophotometer and Flame Photometry, were used for the analyses. The carbohydrate content, crude fat, crude protein, crude fiber, ash content, and moisture content were 40.60%, 2.00%, 17.55%, 9.55%, 14.00%, and 12.00%, respectively, according to the experimental results. Phytochemical analysis revealed that the leaf samples included a high quantity of alkaloids, flavonoids, reducing sugar, phenols, tannins, quinones, and cardiac glycosides. The mineral compositions of the investigated leaf show the presence of Fe (20.49 ± 0.25 Mg/100g), Zn (5.67 ± 0.10 Mg/100g), Mg (23.03 ± 5.10 Mg/100g), K (12.06 ± 0.10 Mg/100g) and Ca (120.98 ± 10.00 Mg/100g). The presence of essential minerals, phytochemicals such as alkaloids, flavonoids, tannins, and cardiac glycosides, as well as carbohydrate and crude protein, suggests that it might function as a spice, food, preservative, insecticide, herbal medicine, fragrance in the cosmetic industry, and alternative source of medicine.
Rereading the story of Hagar in Genesis 16:1-16 as a narrative of prejudice in South Africa.
Authors: Masoga Prof. M.A.
Published: May 2023

The present research is a rereading of the Hagar narrative in view of prejudice in South Africa. Some previous contributions on the Hagar narrative have tended to pursue either exegetical or hermeneutic route. The present research comprises an eight-tier structure. However, the Hagar narrative is explored in lieu of the following two foci. First, a critical exegesis of the Hagar narrative (Genesis 16:1-16) is given. The critical exegesis is a verse-by-verse analysis of the narrative. The analysis seeks to present clarity for the readership where some ambiguity and inconsistency occur in the narrative. For example, the study interrogates the flight of a pregnant Hagar from Sarah in Mamre and travels a journey of approximately 340km to Shur at the border with Egypt. Other misunderstood parts of the text include the enslavement, marriage and mistreatment of Hagar by Abraham and Sarah. Second, a rereading of the Hagar story as a narrative of prejudice in South Africa is explored. It is argued that the attempt is not to regard the narrative as a historical reality and that Hagar will not be discussed as a historical figure. On the contrary, the present study examines the concepts and themes in the Hagar narrative considering the perceived oppression and prejudice devastating post-apartheid South Africa today. The study argues that South Africa has not successfully dismantled apartheid policies by the dawning of majority rule; unemployment, poverty and abortion continue to depict the ‘rainbow nation’ in a bad light. For example, legalization of abortion contradicts the African Ubuntu philosophy. Hence, “…Return to thy mistress and submit thyself under her hands” (Genesis 16:9) suggests a perpetuity of apartheid policies. However, a rereading of the Hebrew phrase translated as “The well of him that lives and sees” (see Genesis 16:14), portrays Hagar envisioning triumph and a dispensation of euphoria beyond her situation of deprivation and prejudice. The study is, therefore, poised towards a feminist discussion of Hagar as an African mother (wife) who was jettisoned to take care of the young children solely and single-handedly. The study utilizes a contextual content analysis as an approach in which secondary data analysis on the Hagar narrative will be explored in light of the biblical text as the primary source. The study revolves around a symbolic interactionism theory.
Priesthood: A family Pastoral Care Vocation in a local Catholic Church in South Africa
Authors: Arima Dr. Cyril
Published: May 2023

The article begins by considering priesthood as a family pastoral care vocation in the local Catholic Church, South Africa. For most priests the priesthood is the superlative gift, a particular calling to participate in the mystery of Christ, a calling which confers on priests the inspiring possibility of speaking and acting in God’s holy name. Pope John Paul II stated that the church prays continuously for new priestly callings and celebrates at the increase in such vocations. Priest make promises relating to the sacrament of the priesthood and these all have great implications. What is essentially in the balance is the word priests ultimately give to Jesus Christ himself. Loyalty to the vocation builds up the holy church, and when there is an act of unfaithfulness this indeed a painful wound to the mystical body of Our Lord. This work deliberates upon the vocation of the priesthood as a career, and it briefly examines and assesses the challenges encountered in promoting the priestly vocation. This includes the manageable number of young people who decide to become priests. Various causes are linked, such as for example the departure from the spiritual life, the disappointment of the missionaries, the induction of young men, the need for participation and commitment. It’s an issue that requires important internal and external collaboration. A critical analysis of the social milieu of local South African Catholic Church serves as a methodology.

This empirical study tried to understand the effects of over-the-top (OTT) streaming platforms on the Indian film industry. The paper analyzes the impact of OTT on both users and technicians of the film industry, highlighting both positive and negative effects. The objective of the study is to explore the changes in the film industry because of the rise in OTT platforms. The methodology of the research involved sending a questionnaire to 100 individuals, which included both users and technicians of the Indian film industry. The sampling techniques used in the study were convenience sampling and snowball sampling. The data collected through the questionnaire was analyzed using statistical tools to get meaningful insights. The study found that the introduction of OTT platforms has led to a significant change in the Indian film industry. While it has provided a platform for small-budget films and new talent, it has also led to concerns about censorship and revenue loss for traditional distribution channels. The study also found that the viewing habits of users have changed, and they now prefer to consume content on their own terms, rather than following traditional schedules and methods. Overall, this study provides valuable insights into the effects of OTT platforms on the Indian film industry. The findings of this study can be used by industry to make informed decisions about the future of the film industry in the digital age.

Polycyclic aromatic hydrocarbons (PAHs) are omnipresent contaminants of the environment, with evidenced harmful effects to human health. Especially endangered are waters, which may affect biota directly or by enabling transport through all environmental compartments. Therefore, constant monitoring of PAHs content in waters is of essential importance. Before most of the analysis, sample preparation is compulsory. Conventional extraction techniques are often time and reagents consuming and not following the rules of “green analytical chemistry”. Thus, miniaturization of classic extraction methods is of high importance to reduce solvent volumes, waste, time of treatment and cost. Recent sample preparation techniques, such as solid phase extraction (SPE), microextraction by packed sorbent (MEPS), solid phase microextraction (SPME), stir bar sorptive extraction (SBSE), dispersive solid phase extraction (dSPE) and dispersive micro-solid phase extraction (D-µ-SPE) were proven as suitable for the extraction of polycyclic aromatic hydrocarbons (PAHs) from water samples and their determination by gas chromatography-mass spectrometry. These sample pretreatments are following “green chemistry” principles, offering the simplicity of operation, reducing costs and time of preparation, without compromising the general analytical parameters of the applied analytical method.
Трансформация подвижности железа в почвах агроэкосистем под влиянием навозных стоков
Authors: Сырчина Надежда Викторовна , Пилип Лариса Валентиновна
Published: May 2023

Важнейшей экологической проблемой промышленного животноводства является необходимость утилизации больших объемов навоза и навозных стоков. В настоящее время основная масса соответствующих продуктов используется в качестве удобрений на ограниченных площадях, расположенных вблизи животноводческих предприятий. Повышенная нагрузка навозом и навозными стоками приводит к трансформации естественных биогеохимических циклов микроэлементов, в частности Fe, в агроэкосистемах. В результате выполненных исследований установлено, что из-за систематического внесения значительных норм навоза крупного рогатого скота и свиней накапливается органическое вещество, повышается рН и снижается содержание подвижных форм Fe в пахот-ных горизонтах почвы по сравнению с кислыми дерново-подзолистыми почвами контрольных участков. Более высокие значение рН были характерны для удобря-емой навозом крупного рогатого скота пашни. В удобряемых навозом почвах со-держание подвижного железа составило 18–25 мг/кг, в почвах контрольных участков – 122–133 мг/кг. Достоверных различий между содержанием подвижно-го Fe в почвах, удобряемых навозными стоками разных видов животных, не вы-явлено. Содержание Fe в зеленой массе кукурузы в конце вегетационного периода варьировало от 90 до 490 мг/кг. Корреляционные связи между подвижностью Fe в агроземе и накоплением этого металла в зеленой массе растений не наблюдались. Более высокое содержание Fe было в кукурузе, выращиваемой в агроземе, удобряемом свиными навозными стоками и имеющем более низкие значения рН. Соответствующий эффект, вероятно, обусловлен повышенной лабильностью хелатных комплексов Fe c фульвокислотами в кислой среде, что облегчает поглощение элемента корневой системой растений. Изучение закономерностей динамики и состояния микроэлементов, в том числе Fe, в агроценозах позволит снизить риски химической деградации агроземов и повысить эффективность органических удобрений.
Разработка коллагенсодержащего икорно-майонезного соуса в рецептуре пресервов «Сельдь атлантическая»
Authors: Воробьев Виктор Иванович , Чернега Ольга Павловна , Яковлева Мария Викторовна
Published: May 2023

Представлена технология коллагенсодержащего икорно-майонезного соуса из малоиспользуемых отходов гидробионтов (лопнувшая, обводненная, незрелая икра и чешуя пресноводных рыб), применяемого в качестве заливки в пресервы. Технология заключается в том, что ястыки икры судака различной стадии зрелости размораживали, промывали водой и разделывали вручную при помощи ножа, отделяя икру от ястычных пленок. Очищенную икру смешивали с водой (массовое соотношение 1:1,2), при необходимости в смесь вносили 1 % поваренной соли и нагревали до 70 °С. В горячую массу добавляли (1–1,5 % от общей массы) коллагенсодержащее волокно, полученное из чешуи судака, образовавшуюся смесь (икорную основу) гомогенизировали и охлаждали до комнатной температуры. Икорную основу смешивали с майонезом «Mr. Ricco Organic Провансаль Classico, 67 %» (майонез) в массовом соотношении 70:30 и добавляли 0,3 % сухой лимонной кислоты, доводя pH смеси до 3,7–4,0. Получен-ный икорно-майонезный соус вносили в пресервы из сельди атлантической в мас-совом соотношении 30:70. При необходимости, для придания икорной основе до-полнительных органолептических свойств, в нее добавляли гастрономическую основу «Паприка» в количестве 0,3 % от общей массы смеси. Разработана рецеп-тура икорно-майонезного соуса, состоящая: из икорной основы – 69,8 %, майоне-за – 28,9 %, лимонной кислоты – 0,3 %. Рассчитан аминокислотный скор белка икорно-майонезного соуса. Икорно-майонезный соус содержит в 3 раза меньше жира и в 3,3 меньше углеводов при увеличении белка в 1,94 раза по сравнению с майонезом.

Authors: Мезенова Ольга Яковлевна
Published: May 2023

Хитинсодержащее сырье представлено в основном ракообразными, это крабы, креветки, раки, криль, гаммарус и др. Россия является мировым лидером по добыче камчатских крабов премиум-класса и северных креветок, которые пользуются высоким спросом у населения. После разделки данного сырья остается до 50 % массы хитинсодержащих отходов, которые в нашей стране прак-тически не перерабатываются и утилизируются. Ценное хитинсодержащее сы- рье – мелкий антарктический криль, вылов которого в России должен начаться в ближайшее время в соответствии со Стратегией развития рыбного хозяйства РФ до 2030 года. Россия также богата мелким рачком-бокоплавом гаммарусом, но лишь его незначительная часть используется в аквариумных кормах. Вторичное хитинсодержащее сырье (отходы от разделки крабов, креветок), а также мелкие рачки (криль и гаммарус) являются ценным органическим сырьем для получения кормовых продуктов. Актуально оценить потенциал сырья с учетом возможности переработки на кормовые добавки методом высокотемпературного гидролиза. Показано, что оно содержит полноценные белки с незаменимыми аминокислота-ми, липиды с полиненасыщенными жирными кислотами, минеральные вещества, углеводы (гликоген и аминополисахарид хитин), каротиноиды и другие биологи-чески активные вещества. В работе представлен анализ вылова сырья, его хими-ческий состав, описаны области использования, предложены рациональные направления переработки в пищевых, кормовых и технических целях. Приведены результаты экспериментов по применению высокотемпературного гидролиза для обработки крабовых и креветочных отходов, антарктического криля с получением пептидно-протеиновых и белково-минеральных добавок. Показана рациональность применения продуктов гидролиза в качестве компонентов в специализированном питании, комбикормах для рыбоводства и животноводства, удобрениях.

The relevance of the development of a preventive direction in the field of mental health care is beyond doubt. Mental health is an integral part and the most important component of the quality of health and includes not only the absence of mental disorders and various forms of disability caused by them, but also the state of mental well-being, in which the individual realizes his individual abilities, can withstand stress loads and be productive in everyday and professional activities. In this respect, the preservation of mental health is at the core not only of the well-being of the individual and his microsociety, but also of the functioning of society as a whole. Mental health care not only concerns the early diagnosis and effective treatment of mental disorders, but also focuses on broad aspects of population psychoprophylaxis and informational psychohygiene, contributing to the promotion of mental health and reducing the prevalence of the most relevant mental disorders. There is evidence of the positive impact of public health interventions on the prevalence of mental disorders. The general principles of the system of psychoprophylaxis imply the organization of three components: psychohygienic, psychoprophylactic and public mental health monitoring. The main directions of implementation of population psychoprophylaxis are: educational, socio-economic, environmental, humanistic and informational. Informational hygiene is a basic element of strengthening the mental health of the population, because a number of effects of informational influence can be predictors of mental ill-being of the population. Approaches to the assessment of informational content for its monitoring for destructive and manipulative content are proposed.
