Resilience and Resistance in the Campus Sexual Assault Literature
Authors: Driessen Molly Catherine
Published: September 2021

Many researchers have focused on documenting the consequences of campus sexual assault (CSA), but there is a dearth of research on students’ post-assault lived experiences. Specifically, there is a lack of scholarship exploring how student victim-survivors of CSA may view, understand, resist, or experience resilience as they navigate post-assault life on campus. The purpose of this paper is to explore the question, “How is resilience described and defined in the literature of CSA?” To respond to this question, I explore other related but distinct concepts that appear in the literature around resilience, including posttraumatic growth, meaning-making, and recovery. Although the focus is on CSA literature, I include scholarship broadly related to trauma, given the limited research specific to resilience and CSA. As a social work scholar and practitioner, I also introduce the significance of this topic within the social work field. Finally, I briefly introduce two theoretical perspectives that have informed and guided the conceptualization of this paper, including socio-ecological and intersectional feminist theoretical perspectives. This conceptual paper was a result of preparation for a qualitative inquiry using phenomenology that aimed to explore the phenomenon of resilience among undergraduate students who had experienced CSA. Suggestions for future work are included.
INFLUENCE OF BLOWING PARAMETERS AND SLAG REGIME ON SILICON AND SULFUR CONTENT IN BLAST-FURNACE CAST IRON
Authors: Kuznetsov M. , Kryachko G.
Published: September 2021

At two blast furnaces (BF) with a volume of 1386 and 1500 m³, the influence of the parameters of blast and slag modes on the content of silicon and sulfur in cast iron was investigated. The blast mode was evaluated by the consumption of pulverized coal fuel (PCF) and oxygen, the slag mode was evaluated by its basicity CaO / SiO₂. It was found that the injection of pulverized coal into the hearth of 1500 m³ BF in the range of flow rates from 108 to 120 g/m³·s, and in the hearth of 1386 m³ BF in the range from 90 to 110 g/m³·s was accompanied by a decrease in the silicon content in cast iron. The deterioration of the transition of silicon into cast iron with an increase in the consumption of pulverized coal is explained by the complex effect of factors that retard the reduction of its oxides. Extreme relationships were also established between the intensity of melting in terms of oxygen consumption and the silicon content in the cast iron of the furnaces under study. The extreme dependences of the studied variables are due to the dual effect of the melting intensity on the reduction of silicon oxides: a reduction in the time of contact of the metal with furnace gases reduces the possibility of transition of silicon into metal, and an increase in the volume of the silicon reduction zone improves these possibilities.
When operating a 1386 m³ furnace on calcium slag in the range of CaO / SiO₂ basicity change from 0.9 to 1.3 without removing the blast furnace operation periods associated with a change in operating conditions, the absence of dependence of the silicon content in cast iron on the CaO/SiO₂ modulus was found/ In its turn this indicated the complexity of factors influencing the reduction of silicon oxides. In the same range of changes in basicity and different operating modes of the furnace, a noticeable effect of basicity on the sulfur content in cast iron was observed, which indicates the decisive role of basicity in the process of blast-furnace desulfurization.
RESEARCH OF FORM CHANGING IN ROLLING HIGH BODIES ON ROUGHING MILLS
Authors: Samokhval V. , Chuyko V.
Published: September 2021

Changing form workpiece in rolling high bodies has its own featuresthat must be taken into account when developing technology. One of the main technological parameters of change form, which largely determines the efficiency of processes, is the rate of spread. Known expressions for the calculation of the spread are obtained for a simple case of rolling, so that for the conditions of rolling high bodies do not provide to determine the spread with acceptable accuracy. Therefore, studies of the peculiarities of changing form during rolling of high bodies remain relevant not only for bloomings, but for rough passages on mills for the manufacture of flat and long products.

The aim of the work is to study the deformation of the metal, in particular spread, when rolling high bodies in rectangular box gauges.

To achieve this goal, the following tasks are solved in the work: design of experimentfor the study of metal spread using existing laboratory equipment; conducting an experiment, analysis of reproducibility of experiments; obtaining a model of deformation of high bodies taking into account the shape parameter of the deformation zone; comparison of the obtained results with the data of other authors and analysis of the accuracy of the model.

From the analysis of publications on dependencies for calculation of spread, a rank number of parameters influencing of spread was defined. Of this series, for the conditions of rolling high bodies, the most significant parameters are the parameter of the shape of the deformation zone and the ratio of the initial dimensions of the workpiece. Experimental studies of the effect of these parameters on the spread were performed using a single box pass embedded in the rolls of the laboratory mill 180. For the conditions and size of the caliber, an experiment of dimension 32 was planned and conducted.

According to the results of the experiment, the dependence for determining the coefficient  spread when rolling high bodies in box passes was obtained. The proposed dependence provides a sufficient level of accuracy in determining the spread within the scope and can be used in the development of technology for rolling high bodies.

From the analysis of the obtained results it is also established that to correctly take into account the effect of limiting the spread of the side walls of box grooves when rolling high bodies, the research area should be spread by supplementing the obtained model with such parameters as ratio depth grooves and stock on spread in the pass.
EXPERIMENTAL STUDY OF STATIC CHARACTERISTICS ASYNCHRONOUS MACHINE IN DYNAMIC BRAKING MODE WITH INDUCTION RESISTANCE IN THE ROTOR WINDING
Authors: Kolychev S. , Sianov А.
Published: September 2021

The article discusses the results of a study of the static electromechanical characteristics of an asynchronous machine (AM) when prototypes of induction resistances (IR) with improved parameters are included in its rotor circuits. The dynamic braking (DB) of asynchronous machines, which is widespread in practice, provides for the dissipation of the kinetic energy of the rotating parts in the resistance boxes included in the rotor winding. In the process of stopping, to maintain a constant average braking torque AM, a bulky relay-contactor circuit for shunting rotor resistances is used. However, it is not possible to eliminate significant fluctuations in the electromagnetic torque in this way. To optimize the DB AM process, it is proposed to include a three-phase  IR in the rotor winding instead of resistance boxes, the value of which automatically decreases along with the rotor current frequency. This approach allows you to abandon contact equipment and ensure smooth braking of the machine with fluctuations in the electromagnetic moment in narrower limits. The known IR designs are designed for starting modes of induction motors with a wound rotor, but they cannot ensure the constancy of the torque on the AM shaft in the DB mode. Therefore, the purpose of the study is to develop and experimentally confirm the effectiveness of simple control circuits of an induction machine in the specified mode with improved contactless induction rheostats in the rotor. The paper presents a diagram of a pilot plant and a figure explaining the design features of the IR. The studies were carried out for an asynchronous machine of the MTB-412-8 type, equipped with a thyristor exciter and a tachogenerator. The three phases of the AM rotor included ICs connected by a "star". The experiments were carried out in the direction of obtaining the necessary braking characteristics of the AM by varying the switching circuit of the stator phases and the value of the current supplying them. The figures show the mechanical characteristics of AM, obtained in the process of studying the influence on them of three typical circuits for switching on the phases of the stator winding and two values ​​of the fixed supply current. The research results show that the desired form of the mentioned AM characteristics is achieved only when using the stator phase switching in a function of the rotor speed and a constant supply current value.

Zoos were created with objectives that diverge from the present reality, currently focused on the conservation of species, environmental education and scientific research, not only for the entertainment of man. In order to improve the lives of animals kept in captivity, environmental enrichment promotes stimuli that provide animal interaction with the environment and with other beings, making it possible to express behaviors common to their species, thus increasing the degree of well-being. It can be applied in five different methods: social, physical, sensory, cognitive and food, in view of the objective to be applied, behaviors and habits of each species. The enclosure must present the needs that the captive requires, resembling to the maximum with the natural habitat and the reality in free life. The lack or inefficient application of enrichment can lead to numerous problems, such as increasing rates of depression, anxiety, stress, reducing reproductive rates and among others that will be presented in more depth in this work. The present study covered a collection of bibliographies that highlight the role of zoos over the years and the relevance of environmental enrichment in the enclosures added to animal welfare and better quality of life.

Let $f$ be an entire function with $f(0)=1$, $(\lambda_n)_{n\in\mathbb N}$ be the sequence of its zeros, $n(t)=\sum_{|\lambda_n|\le t}1$, $N(r)=\int_0^r t^{-1}n(t)\, dt$, $r>0$, $h(\varphi)$ be the indicator of $f$, and $F(z)=zf'(z)/f(z)$, $z=re^{i\varphi}$. An entire function $f$ is called a function of improved regular growth if for some $\rho\in (0,+\infty)$ and $\rho_1\in (0,\rho)$, and a $2\pi$-periodic $\rho$-trigonometrically convex function $h(\varphi)\not\equiv -\infty$ there exists a set $U\subset\mathbb C$ contained in the union of disks with finite sum of radii and such that
\begin{equation*}
\log |{f(z)}|=|z|^\rho h(\varphi)+o(|z|^{\rho_1}),\quad U\not\ni z=re^{i\varphi}\to\infty.
\end{equation*}
In this paper, we prove that an entire function $f$ of order $\rho\in (0,+\infty)$ with zeros on a finite system of rays $\{z: \arg z=\psi_{j}\}$, $j\in\{1,\ldots,m\}$, $0\le\psi_1<\psi_2<\ldots<\psi_m<2\pi$, is a function of improved regular growth if and only if for some $\rho_3\in (0,\rho)$

"The study aims to compare different screening methods that are currently being used to confirm a cervical intraepithelial lesion (CIN) underlying the inherent advantages of the varied examination procedures. In this study we are looking at the quality contrast of the different paraclinical examinations relative to the cost, invasiveness and cultural acceptance of such procedures. Every year, more than 100,000 women in EU countries are diagnosed with cervix uteri cancers (CCU). This type of cancer can be prevented if precancerous cells are detected and treated. HPV is found in over 90% of cervix uteri cancers. In Europe, more than half of the countries have implemented screening programs for cervical cancer, and most European countries now have national HPV vaccination programs, however target populations vary depending on the epidemiological evidence and the budgetary level of each countries health system. In this study we evaluated and compared the current and modern techniques used for cervix cellular diagnostics. Also, this study helps improve the understanding on the economic and social implications of screening among female population and the impact it has on healthcare system relieving. Romania recorded an incidence of 22.6 cases of cervix uteri cancers / 100.000 women (age standardized rate), and a mortality of 9.6 / 100.000, ranking second highest in the EU zone."
MULTICOMPONENT DEPOSITS WITH BY-PRODUCT AS THE MAIN SOURCE OF FELDSPAR RAW MATERIALS FOR MODERN TECHNOLOGIES
Authors: Rudko Georgii , Kyrilo Mariia , Ozerko Maksym
Published: September 2021

"Feldspar is raw materials with a growing volume of production every year, as well as a price for it. Feldspar consumption has been gradually increasing in ceramics, glass industry for solar panels, housing, and building construction. Feldspar raw materials include intrusive, effusive rocks, weathering crust of crystalline rocks, sedimentary altered and altered rocks, as well as partially medium and basic aluminosilicate rocks. It was defined an industrial application for each species of feldspar. Potassium feldspars (orthoclase, microcline, sanidine) are used in electroceramic, electrode, abrasive, and ceramics industries. For these productions, the potash module is fixed in a ratio of 2: 1. For some industries, in particular the manufacture of high-voltage ceramics, the necessary feldspars are as close as possible to pure potassium (with a modulus of at least 4: 1, which corresponds to 80% of the orthoclase component). Potassium-sodium raw materials, from a potassium modulus of at least 0.9, are used for building construction. Sodium minerals with non-standardized potassium modulus are used for the glass industry, the production of enamels, and products such as vitreous porcelain. Calcium feldspars, represented by plagioclase of higher numbers, have limited practical application and their presence in feldspar concentrates is undesirable. According to mineral associations, all types of feldspar raw materials can be divided into five types: 1) feldspar (syenites, trachitis); 2) quartz-feldspar (pegmatites, granites, sands, etc.); 3) nepheline-feldspar (nepheline syenites, alkaline pegmatites); 4) quartz-sericite-feldspar (shales, secondary quartzites); 5) quartz-kaolinite-feldspar (sands, alkaline kaolins, secondary quartzites). It is shown on the example of Ukrainian deposits of feldspar minerals that complex deposits with by-products become the main source for production. Especially if these are new mining operation facilities. The authors have identified three main types of such complex multicomponent deposits: 1) deposits of intrusive rocks where weathering crust of crystalline rocks are mined as a byproduct; 2) complex deposits, where feldspar rocks are enclosing or overburden and can also be considered as byproducts; 3) deposits where feldspar concentrate can be produced as a product of ore components processing."

The establishment of the state of the massif by a diagnosis on different forest plots is part of a project of monitoring and silvicultural management. The purpose of this study is to assess the health status of the Ouled Bechih forest. The methodology used was the visual assessment of the tree crown of the dominant species (i.e. Quercus suber and Quercus canariensis) according to the protocols DEPEFEU, DEPERIS and ICP Forests. These protocols were selected for adoption based on field observations and their applicability in record time. The results obtained indicate that the health status of the trees within the studied plots is declining. The DEPEFEU value index shows an average of 1.75 for Quercus suber and 2.6 for Quercus canariensis while the DEPERIS has an average level of 2.36 Q. suber in and 3.37 in Q. canariensis. ICP Forests has also contributed to providing clearer information on the consequences of this health situation by deducting an average visibility rate of 1.20 and 2.63; social status of 1.17 and 3.11 and competition of 1.11 and 2.49 for Q. suber and Q. canariensis respectively. In general, the health status of the tree crown is average and almost adapted to the environmental conditions. In contrast, the carrying capacity of biodiversity is low and needs to be improved.

Los estudios sobre trayectorias escolares se caracterizan por analizar las trayectorias de los estudiantes de manera lineal (trayectoria teórica), sin tomar en cuenta los recorridos biográficos que los estudiantes construyen durante su proceso educativo. El presente estudio tuvo un doble objetivo. En primer lugar, se pretendió conocer la representación social de las trayectorias escolares biográfica en el estudiantado del bachillerato sinaloense. En segundo lugar, se analizó la noción de polifasia cognitiva presente en la representación. Se aplicó una entrevista semiestructurada a 10 estudiantes de bachillerato, con una media de edad de 17 años ( DT= .77). Los resultados muestran que los discursos de la representación sobre trayectorias biográficas de éxito y fracaso escolar se encuentran vinculados. Por una parte, se presentan elementos comunes que hacen referencia a tres discursos: a) las experiencias sobre la transición educativa; b) las estrategias didácticas del profesorado y; c) la construcción familiar del futuro académico. Por otra parte, los elementos contradictorios que evidencian la polifasia cognitiva se a la forma en que el estudiantado representa su trayectoria escolar que puede ser de éxito (éxito, persona, escuela, lograr, sociedad, ejemplo ) o fracaso escolar (fracaso, característica , malo, irresponsable, experiencia).
Scientific and practical basis for the use of probiotics to improve the quality of poultry products
Authors: Оrishchuk О. S. , Tsap S. V.
Published: September 2021

Science and practice have proved that balanced nutrition involves the intake of the organic, mineral, and biologically active substances in the bird’s body in certain quantities and proportions due to their needs. Balanced poultry feeding is a guarantee of not only high productivity, but also the prevention of diseases that negatively affect the safety of livestock and product quality. Providing poultry with high-quality protein is especially important nowadays. Birds spend more essential amino acids per unit of body weight gain and, accordingly, more of them should be daily supplied to the body with feed. Plant proteins are the basis of grain feeds that contain all eleven essential amino acids required for protein synthesis in the body of chickens, ducks, geese, and turkeys. However, it was revealed that most of these amino acids are concentrated in grain in insufficient quantities and cannot fully satisfy the needs of highly productive poultry. As a result, it is necessary to additionally introduce high-protein supplements into the diet as a source of essential amino acids or use synthetic concentrates of lysine, methionine, threonine, and tryptophan. High-protein supplements are coming in two types – animal and plant-based. From the plant-based ones, soy products are considered the most valuable as a concentrated source of the first limiting amino acid - lysine, and sunflower meal is rich in methionine. And even so, plant-based protein feed is not able to create a complete balance of all essential amino acids. This can be done only if the animal-sourced protein is introduced into the poultry diet in the form of fish meal, meat and bone meal, meat meal, or yeast. Besides, scientific research has proven that yeast can be considered a wonderful natural source of B vitamins. The analysis of scientific research indicates that today there is a wide search and study of various feed supplements that could be a source of complete protein and have in its composition a complete complex of amino acids for birds. There are not enough such high-quality feed additives in Ukraine, and those coming from abroad are distinguished by high cost and are often falsified. Therefore, the use of yeast in poultry diets as long as their industrial production according to the technology based on the state standard is relevant for solving a number of modern poultry farming problems and is of great scientific and practical importance.

Published: September 2021

Owing to the vast number of choices open to customers, they can often feel paralysed in their decision-making. Offering a wide range of options can activate the effect of Decision Paralysis, which delays the client's final decision. The impact of Decision Paralysis can prevail in restaurants. This study reveals the existence of decision paralysis among customers in restaurants when placing an order. The aim is to investigate the prevalence of Decision Paralysis among customers, with particular reference to placing an order in a restaurant and the influence on consumers’ purchase decisions. A survey questionnaire was rolled out using Google forms to customers who have experienced dining in a restaurant. A total of 416 survey responses were collected for data analysis through the convenience sampling method. It was found that, customer purchase decision has been affected by the decision paralysis effect. It was also found that customers experience a dilemma due to tremendous options or choices in the food sector by the service providers. This study was limited to restaurants and in terms of cuisine, with hotels not being considered. Hence, the main limitation is not being able to generalise the findings of this study to the whole of the food catering sector. The study will benefit both scholars and marketing practitioners in understanding the difficulty a customer faces during purchase decision-making.

Self-concept, one of affective introductory behaviours, is one of the most frequently studied issues especially in social sciences. Since it is a strong mental structure which psychologists and social psychologists say to be related with learning, this research aims to adapt Chemistry Self-Concept Inventory developed by Bauer (2005) so as to evaluate students’ self-concept into Turkish, and analyse its psychometric properties. The data were collected by applying the inventory to 530 prospective teachers attending the chemistry education, primary school education and science education departments of three different Universities. Following the translation work, Turkish form of the inventory was given the final shape. The construct validity of the inventory was tested by confirmatory factor analysis. McDonald’s Omega (ω) and Cronbach Alpha (α) coefficients were calculated for the reliability study of the inventory. Fit indices were found to be lower in the first confirmatory factor analysis conducted than the ones expected, and 11 items with the fewest factor loads and with the highest modification indices were removed from the inventory. The sub-dimensions apart from creativity were found to have ω and α coefficients above 0.70.

This research aims to determine whether Problem-Based Learning (PBL) helps in fostering scientific creativity among fifth graders. Students’ scientific creativity (SC) was investigated in the product dimensions of (a) solving scientific problems, (b) understanding scientific phenomena, (c) advancement in scientific knowledge, and (d) improvisation skills with a technical product. A pre-test and post-test single group experimental design was employed. Pre-test measures on SC were administered to 232 fifth graders. Students participated in PBL hands-on activities that required solving open-ended problems. After these were completed, post-test measures on SC were assessed. Students' reactions to the PBL experience were also recorded. The results of paired sample t-tests showed significant differences in all product dimensions of SC, except in the understanding of scientific phenomena. Further analysis found significant differences among the creativity traits of fluency, flexibility and originality in each product dimension of SC, except in the originality in the advances of scientific knowledge. Students felt that the PBL activities were easy, fun, and interesting as well as a practical way of gaining and advancing science knowledge. Students also found their participation in sharing ideas in cooperative learning groups inspired them to be more creative. This research suggests that the PBL activities have a positive impact in fostering student’s SC in science lessons.

Se analiza la variación de la radiación incidente en la zona de Urbina (UTM x754579,y9835357; 3646 msnm), ubicada en la región del páramo Altoandino de la provincia de Chimborazo, con la finalidad de conocer su dinámica y los efectos de la posición geográfica y altura respecto al nivel del mar, usando la Teoría del Caos. Para controlar los datos anómalos se aplicó el método de reducción del ruido no lineal simple; luego se procedió a realizar una reconstrucción en el espacio de las fases multidimensional, determinando los coeficientes de Lyapunov, entropía y dimensión fractal del sistema, permitiendo describir su dinámica y la variación en el tiempo. Se demuestra que es un sistema caótico (no lineal), al presentar más de un coeficiente positivo de Lyapunov. Además, se predicen los datos en el tiempo y se verifica que no hay diferencias significativas entre las series medidas y predichas, usando el método Bootstrap.

Minyak kayu putih merupakan salah satu hasil hutan bukan kayu yang memiliki nilai ekonomi tinggi dan dapat dimanfaatkan untuk kehidupan sehari-hari. Saat ini permintaan minyak kayu putih diperkirakan akan terus meningkat dengan bertambahnya populasi penduduk dunia dan berkembangnya berbagai industri yang memanfaatkan minyak kayu putih. Tujuan penelitian ini adalah untuk mengetahui tingkat pendapatan, kelayakan usaha petani HHBK kayu putih (Melaleuca cajuputi) dan sistem pemasaran hasil panen kayu putih (Melaleuca cajuputi). Lokasi penelitian terletak di Hutan Lindung Desa Montong Sapah Kecamatan Praya Barat Daya Kabupaten Lombok Tengah Provinsi Nusa Tenggara Barat. Metode yang digunakan dalam penelitian ini adalah metode deskriptif, teknik pengumpulan data dilakukan dengan teknik survey dan wawancara dengan menggunakan alat bantu kuisioner terhadap 14 responden yang dilaksanakan pada bulan januari 2020. Penentuan responden dilakukan dengan random sebanyak 15% dari jumlah petani HHBK kayu putih (Melaleuca cajuputi) yang tergabung dalam Kelompok Tani Hutan Tenem . Hasil penelitian ini menunjukkan bahwa tingkat pendapatan petani dalam kisaran waktu 1 tahun adalah sebesar Rp. 2.901.000, rata-rata tiap kali panen dalam kisaran waktu perdua bulan sebesar Rp. 792.000 dan tingkat kelayakan usaha dimana R/C Ratio menunjukkan 2,58 ≥ 1,3 yang berarti menguntungkan, maka usaha ini layak dilanjutkan. Dalam analisis pemasaran menunjukkan bahwa petani menjual kayu putih ke satu tempat (monopoli) dengan 2 sistem pembayaran yang dilakukan oleh pihak pembeli yaitu 64% pembayaran langsung dan 36% pembayaran kemudian. Untuk meningkatkan pendapatan maka diharapkan petani meningkatkan usaha pemeliharaan seperti pemangkasan (prunning) sesuai petunjuk teknis kemudian perlu adanya campur tangan pemerintah untuk menentukan harga jual daun kayu putih ,mencari informasi pasar untuk mendapat nilai jual maksimal atau optimal  dan frekuensi kerja penyuluh lebih ditingkatkan kembali

Kayu putih (Melaleuca cajuputi) merupakan jenis dari famili Myrtaceae yang mengandung minyak atsiri berpotensi mendukung industry minyak atsiri dan juga digunakan untuk kegiatan rehabilitasi lahan. Tujuan dari penelitian ini untuk mengetahui pengaruh media tanam terhadap pertumbuhan bibit tanaman kayu putih. Metode yang digunakan dalam penelitian ini yaitu metode eksperimental menggunakan rancangan acak lengkap (RAL) yang terdiri dari 1 faktor perlakuan yaitu media tanam (M) yang terdiri dari 5 aras (tanah, tanah:pasir (2:1), tanah:pasir (1:2), Tanah : Pasir Zeolit Mikoriza (1/10%), dan tanah:kompos (1:1) ) dengan masing-masing tiga pengulangan. Parameter pertumbuhan yang diamati yaitu tinggi tanaman, jumlah daun, diameter batang, dan panjang akar. Analisis data menggunakan uji anova pada taraf uji 0,05. Jika terdapat perbedaan yang nyata, maka dilakukan uji lanjutan BNJ. Hasil yang diperoleh dari penelitian ini yaitu media tanam memberikan pengaruh nyata kepada parameter pertumbuhan jumlah daun, sedangkan pertumbuhan tinggi tanaman, diameter batang dan panjang akar tidak memberikan pengaruh yang nyata terhadap parameter perlakuan. Media tanam M3 (tanah + pasir Zeolit Mikoriza 1/10%) memberikan pengaruh lebih baik dibandingkan dengan media lainnya pada parameter tinggi tanaman dan jumlah daun. Hasil uji Anova menyatakan media tanam tidak berpengaruh signifikan terhadap tinggi tanaman dan panjang akar. Sedangkan pada jumlah daun memberikan hasil berpengaruh signifikan pada minggu keenam.
