CHAOTIC OSCILLATIONS OCCURRING IN A HYDRAULIC CIRCUIT:Digital Simulation and Experimental Study

This paper deals with chaotic oscillations occuring in a hydraulic circuit consisting of a poppet valve and a pipeline terminating at a constant pressure tank. The circuit with a long pipeline becomes unstable and various kinds of oscillations are self-excited. In this study, it is shown by digital simulations that irregular solutions are obtained from a deterministic mathematical model for the dynamics of the circuit in addition to periodic or almost periodic oscillations. The irregular solutions which are considered as a kind of chaotic phenomena are classified into (a) period-doubling type, (b) Ruelle-Takens type, and (c) intermittent type. Experimental results are qualitatively in good agreement with theoretical ones.
Observing a residential school for the deaf: identifying factors in creating a deafcentric environment

Among many Deaf education programs in the United States, residential schools for the Deaf have a long and valuable history for the Deaf community as centers of cultural and linguistic transmission of U.S. Deaf culture. Several states maintain well-populated Deaf education programs that provide language and culturally rich environments wherein Deaf students receive American Sign Language (ASL)/English Bilingual instruction. In such an environment, which could be considered a Deafcentric setting, students are able to interact with their teachers, classmates, principals, and the staff in their native, natural language. Those schools are also designed to provide extracurricular activities with Deaf mentors, another key means of transmitting and nurturing Deaf culture. The purpose of this study is to identify the linguistic and socialization factors—inside and outside the classroom—of one known Deafcentric school in providing quality education that promotes self-advocacy and leadership skills for Deaf students. This research used a simple descriptive qualitative research design, including site observations (two classrooms, an after-school activity, and a dorm tour); interviews with a selected administrator and two educators (one with >15 years of experience and one with < 5 years of experience); and document (mission, policies, outreach information) review. The findings suggest that the use of visual instructional techniques, the creation of a visual learning environment, the respect for and consistent use of ASL in and out of the classroom, and the positive attitude of teachers and administrators towards providing a bilingual environment are key indicators in creating a Deafcentric environment at this school.

Changing Role of Liver Biopsy Indications in A Tertiary Care Centre

Background: The histomorphological study of liver biopsy is the best means to ascertain the nature and signifi¬cance of pathological processes occurring in the liver. The current non-invasive tools are unqualified to replace liver biopsy in clinical practice. Methods: This is a one year prospective study from January 2017 to 2018. A total of twenty five cases suspected to have chronic parenchymal liver disease, inflammatory lesions or neoplastic lesions were included in the study. Detailed history and investigations done including biochemical parameters, radiological and other investigative procedures done were recorded and percutaneous liver biopsy was done using trucut needle. Results: Out of the total 25 liver biopsy done, 60% cases were male, 40% were females. Majority of the patients belonged to the sixth decade (32%). Youngest patient was a 12 year boy with history of intermittent jaundice since birth, and the oldest patient was a 78 year old male. The most prevalent pathological diagnosis was cirrhosis with steatohepatitis with 7 cases (28%), followed by Non Alcoholic Fatty Liver Disease (NAFLD) and autoimmune hepatitis, 12% each. Conclusion: Liver biopsy is the gold standard for diagnosis of chronic liver diseases and plays a valuable role in diagnosis, prognostic and management of liver diseases.
A Tourists' Travel Intention in the Context of Covid-19 in Viet Nam

The novel coronavirus pneumonia has seriously affected the development of tourism in Vietnam and even the whole world. Combining the current of VietNam's mitigation and the gradual recovery of tourism, this paper puts the research perspective on tourists' travel intention, and constructs a new theoretical structure by using TPB and TRA theory, This study presents the findings of a research which examined the relationship Subject norms and perceived behavioral control have a significant impact on Attitude and tourists' desire to travel; the Attitude and desire to travel has a significant positive impact on tourists' travel intention, a little empirical study investigates these relationships together. This article investigates these relationships using SEM with data 437 tourists in the Vietnam. Findings of the study revealed that Attitude mediates the relationship between Subject norms, Perceived Behavioral Control, and Travel intention. Desire to travel mediates the relationship between Subject Norm, Perceived Behavioral Control and Travel intention. Based on the study findings, implications for theory and practice are discussed.
Role of STIM (Stromal interaction molecule) in Store operated calcium entry

Store operated calcium entry (SOCE) is controlled by the ER-resident Stromal Interaction Molecule 1 (STIM1) which senses a decrease in [Ca2+]ER and opens Ca2+-selective channels of the Orai and TRPC families. The oligomerization of STIM1 initiated by a drop in [Ca2+]ER is the crucial step for SOCE activation, and by analogy SOCE termination is thought to be controlled by the de-oligomerization of STIM1 initiated by the restoration of physiological [Ca2+]ER levels. We quantify the [Ca2+]ER dependence of STIM1 oligo-/deoligo-merization during physiological stimulation of HeLa cells, using the D1ER to measure [Ca2+]ER and FRET between CFP-STIM1 and YFP-STIM1 to monitor STIM1 oligo-/deoligo-merization. We found that the kinetics of STIM1 oligomerization follow the kinetics of store depletion independently of the type of stimulation used. We also showed that, in addition to store refilling, a local increase in the cytosolic Ca2+ concentration is required to initiate STIM1 de-oligomerization.
Knowledge among Dentists about the usage of Opioid analgesics in Dental Practice

The treatment of pain is very common in dental practice. Analgesics is the safest way to relieve pain. Conventional analgesics are known as opioids and nonopioids, although the old words "narcotics" and "non-narcotics" continue to be used interchangeably. Dependence and resistance are well recognized characteristics of daily use of opioid analgesics, but this does not automatically hinder use in palliative care.The dentist should have a clear knowledge in prescribing opioid drugs to the patients. To assess dentists regarding knowledge, attitude and opinion on prescribing opioid analgesics in dental practice. A close ended questionnaire comprising of 10 questions regarding knowledge, precautionary measure, indication, guidelines in prescribing opioid analgesics in dental practice will be distributed to 100 dental practitioners. Data was tabulated and analysed by computing the percentage response for each question. Majority of the practitioners (83%) were aware and some of them (17%) were unaware regarding the usage of opioid analgesics in dental practice. Most of the respondents in this study knew the background of opioid drugs, indication, contraindication and their usage in dental practice. However, dentists should be cautious in prescribing any form of drugs to the patient.
ToxoGRA15II promote macrophages polarization against Hepatic carcinoma by targeting TRAF6

Background: There is increasing evidence that tumor-associated macrophages play an important role in the development of tumors. The more macrophages, the faster the tumors develop. On the one hand, studies have shown that the dense granule protein molecule of Toxoplasma gondii (ToxoGRA15II) tends to induce the differentiation of classically activated macrophages (M1). GRA15II can also induce M2 reversal polarized to M1. Promote the occurrence of Th1 immune response.Methods: Here, we constructed LV-gra15Ⅱ, which was transferred to M1-like and/or M2-like macrophages. Furthermore, we injected LV-gra15Ⅱ by vein into tumor bearing C57BL/6 mice.Results: We found that M2-like macrophages could be polarized to M1-like macrophages, inducing NO, IL12, TNF-αexpression. Mechanistically, ToxoGRA15Ⅱ activate NF-κB signaling pathway by binding to TRAF6. Additionally, LV-gra15Ⅱ promoted p65 nuclear translocation to polarize TAM to M1-like macrophages and induce IFN-γ,TNF-α,IL12, NO expression, inhibiting tumor growth. Subsequently, ToxoGRA15Ⅱ has a role in cancer pathway and metabolism.Conclusions: Taken together, these findings could lead to the development of immunotherapy strategies to tumor, due to ToxoGRA15Ⅱ as polypeptide effector molecule of T.gondii and non-toxicity to mammalians.

Impact of Dividend Policy on Share Price of Listed Ict Firms in Nigeria

This study empirically investigated the impact of Dividend Policy on Share Price of Firms Listed on ICT Sector of Nigerian Stock Exchange. In order to determine the relationship between dividend policy and share price of firms, dividend policy key proxy variables were used in the study, namely; Dividend Payout (DPO), Dividend Per Share (DPS) and Dividend Yield (DY) while Share Price (SP) on the other hand was measured using Market Price of Shares (MPS). Three hypotheses were formulated to guide the investigation and the statistical test of parameter estimates was conducted using OLS Model operated with STATA 15. Ex Post Facto Design was adopted and data for the study were obtained from the Nigerian Stock Exchange Factbook and Annual Reports and Accounts of listed ICT firms in Nigeria spanning from 2016-2020. The findings generally indicate that Dividend Payout, Dividend Per Share & Dividend Yield have exerted significant and positive impact on Firms Share Price at 1% significant level. Based on this, the study concludes that dividend policy is capable of influencing firms’ share prices in Nigeria. By this implication, the study supports the relevant theories of dividend policy reviewed in this study as irrelevant theories of dividends do not hold in the case of Nigeria. The study recommends among others that firms’ willing to maximize share price should consistently increase their dividend payment as this sends signal to the investors about the firm’s market performance and financial health.
The Effect of Motivation on Financial Literation

Small and Medium Enterprises (SMEs) have a big role in the economy, especially in developing countries. However, in its role, Indonesia still has a level of access to finance below several ASEAN countries such as Singapore, Malaysia and Thailand. Thus it can be said that the literacy of SMEs in Indonesia is low. This study considers one of the factors that influence financial literacy, namely motivation. The method we use for this research is direct interviews and using a questionnaire as a data collection tool. We have successfully interviewed one hundred and ninety-one UKM located in Malang. The results showed that the motivation of small business actors had a significant effect on financial literacy. Based on this, the government together with financial institutions need to formulate the right program. Apart from the education provided by educators, the program can also take the form of socialization and consultation services, either directly or indirectly. Development of supporting infrastructure and public access to financial institutions, products or services according to their needs and capacities also need attention for immediate optimization. Keywords—motivation, financial literacy, UKM
Comparative Study of the Flexural Strength and Impact Strength properties Between Two Types of the Ternary Polymer Blends

Compatibility is one of the major problems which effect on the characteristics of polymer blends. Therefore, in the current search Polypropylene Grafted Maleic Anhydride (PP-g-MA) was used to improved compatibility between the components of the binary polymer blends. So, two sets of ternary polymeric blends were prepared by melt-mixing method using double-screw extruder. The first group is containing on (polypropylene (PP): 1% (PP-g-MA): X% polymethylmethacrylate (PMMA), the second group consists of (PP: 1%(PP-g-MA): ultra-high molecular weight polyethylene (UHMWPE)). The blends, containing between 5 to 20% ratios of a third material (PMMA or UHMWPE) and 1% of compatibilizer material (PP-g-MA). Investigation the bending strength and impact strength was done for the prepared specimens. Study shown that, the polymer blends (PP: 1 %(PP-g-MA): X% PMMA) gained the higher properties in flexural strength, whereas the polymer blends (PP: 1% (PP-g-MA): X% UHMWPE) have got the higher values in impact strength and fracture toughness.
Training for handling official pistol according to international standards

A shooting training was carried out according to international standards model on a sample of 21 students of second year of Advanced School of Internal Affairs (VSUP) in Belgrade, who have already had previous knowledge in handling the official firearms. During the realization of the program the students had three tests - at the beginning of the training (Test 1) after 50% of the realized training (Test 2) and at the end (Test 3).

The results have shown that the initial level of knowledge (Test 1) was 48.29±22.98 of the total hit circles. At the transitive testing (Test 2) the efficiency was at the level of 76.95±11.83 of the total hit circles, while at the end the efficiency was at the level of 78.09±11.42 of the total hit circles. Analysis of the variance (ANOVA) has shown that there is a general statistic difference between the testing results, at the level F=22.502, p=0.000. The student test has shown that between Test 1 and Test 2, as well as between Test 1 and Test 3 there are significant differences in shooting efficiency, at the level of t=6.117 p<0.000 and t=7.892, p<0.000 respectively. The result is a mathematical model described as the following equation: y=35.1114x 01406, and the model has the power of prediction at the level of reliability 98.73%.
Nutritional Implications For Oxidative Status, Immune Function, And Energy Metabolism In Transition Dairy Cows And Relationships With Postpartum Performance And Endometritis

Multiparous Holstein cows (n=60) were used to determine effects of trace mineral source on oxidative metabolism, cytological endometritis, and performance of transition cows. After a 1-wk pretreatment period, cows were assigned randomly to one of three dietary treatments from 21 d before expected calving through 84 d post calving. Dietary treatments administered by daily topdress included: 1) Inorganic sources based upon sulfates of zinc (Zn), copper (Cu), and manganese (Mn; ITM); 2) a blend (75:25) of sulfates and chelated sources of Zn, Cu, and Mn (ITM/OTM); and 3) hydroxy trace minerals (HTM) of Zn, Cu, and Mn. The resulting dietary concentrations of supplemental Zn, Cu, and Mn were similar among treatments and averaged 40, 10, and 27 ppm, respectively, before calving and 59, 15, and 40 ppm, respectively, after calving. An interaction of treatment and week existed for milk yield such that cows fed HTM increased milk yield faster than cows fed the other two treatments; a similar interaction was also present for yields of fat-corrected milk and lactose. Cows fed HTM during the prepartum period tended to have higher body weight and had higher body weight during the postpartum period than those fed either of the other two treatments. Plasma antioxidant capacity was lower in cows fed HTM 1 Research material published in part as abstract in 2012 (Yasui et al., 2012 )
Evaluation of Some Sugar Beet Varieties Under Sabahia and Nubaria Regions Conditions

Two field experiments were carried out at Sabahia, and Nubaria regions during 2016/2017 and 2017/2018 seasons, to evaluate ten varieties of sugar beet under Sabahia and Nubaria conditions. The experiments were conducted in split plot design with three replications, where the main plots assigned by the two location (Sabahia and Nubaria), while the sub plots were occupied by the ten varieties of sugar beet (Charelston (V1), Gazella (V2), Heba (V3), Lilly (V4), Mammut (V5), Matros (V6), Nancy (V7), Oscarpoly (V8), Puma (V9), and Pyramidia (V10). The results revealed that there was significant difference between the two locations and the cultivated verieties for most of studied characters, whereas planted each of Pyramidia, Puma and Oscarpoly under Nubaria and Sabahia region getting the highest yield, yield components and quality of sugar beet crop. Other cultivars under this study could be employed as other sugar beet genetic resources with reasonable root and sugar yields in such sandy soil of the Nubaria region.
Application of contemporary engineering techniques and technologies in the field of dental prosthetics

Purpose: During the last couple of decades, development of medical science has been marked with an ever more pronounced interdisciplinary character which, in part, can be attributed to various engineering applications. Rapid development of computer-aided technologies, which completely transformed production engineering, also left an indelible mark on dental prosthetics. Striving towards its primary goal primum non nocere (’Above all, do not harm! ’), the area of dental prosthetics has introduced numerous novel technologies and methods which allow manufacture of precision, custom-made, optimal dental replacements. Design/methodology/approach: The aim of research to contribute to integration of modern engineering technologies and computer-aided systems into dental prosthetics with special emphasis on efficient manufacture of dental replacements with precision which allows clinical applicability. The subject scope of the paper comprises modelling, manufacturing with special emphases on materials, quality inspection and environmental impact assessment (cleaner production). Findings: In the industrially developed countries, efforts have been concentrated towards advancement of modelling and manufacture of dental replacements by introducing modern computer equipment and state-of-the-art materials and machining technologies. However, in countries in transition, dental replacements are predominantly manufactured in a traditional, manual way prone to errors. The reasons for this situation are various. Practical implications: It is expected that this trend will have a significant impact on the further development of production engineering techniques and technologies in the near future. Originality/value: The paper evolved on the premise that there is a room for more intensive co-operation between the two disciplines dental prosthetics and engineering, with a prospect for success of the development of novel, original solutions. In that sense, this paper should serve to both professions – production engineers and dentists.
