A FAMILY OF INTEGER SOMOS SEQUENCES

Somos sequences are sequences of rational numbers defined by a bilinear recurrence relation. Remarkably, although the recurrences describing the Somos sequences are rational, some Somos sequences turn out to have only integer terms. In this paper, a family of Somos 4 sequences is given and it is proved that all Somos 4 sequences associated to Tate normal forms with h−1 = ± 1 consist entirely of integers for n ≥ 0. It is also shown that there are infinitely many squares and infinitely many cubes in Somos 4 sequences associated to Tate normal forms.
Comparative analysis of genetic diversity of bread wheat genotypes based on protein and DNA markers

Huseynova, E. , Gaziev, A. , Abbasov, M. , Babayeva, S. , Haciyev, E. , Karimov, A. , Sadiqov, H. , Rustamov, Kh. , & Akparov, Z. (2018). Comparative analysis of genetic diversity of bread wheat genotypes based on protein and DNA markers. Bulgarian Journal of Agricultural Science, 24(6), 1034–1041 Genetic diversity of 32 local and 23 introduced bread wheat (Triticum aestivum L.) genotypes was studied using protein and inter simple sequence repeat (ISSR) markers. A total of 26 bands were amplifi ed using 5 ISSR primers. The number of polymorphic bands varied from 1 to 3, averaged 2.2. The average genetic diversity for the whole bread wheat collection based on ISSR data was 0.57. Polymorphism rate of protein markers were superior to ISSR markers. The highest number of patterns was noted at α and ω sections, with 44 and 42 patterns, respectively. Genetic diversity index was high for all studied sections. The maximum diversity was observed at α section (0.968), followed by ω section (0.963). Mantel test did not reveal signifi cant correlation between dendrograms created, based on protein and DNA markers, suggesting that both set of markers explore genetic variation differently. In the ISSR dendrogram some tendencies were observed in grouping of genotypes according to their botanical varieties, while no relationship was found between grouping of genotypes and their origin or botanical variety based on protein markers.
The Usefulness of Including Women in Household Solid Waste Management . A Case Study of Dzivaresekwa High Density Suburb ; Harare

The study was conducted in Dzivaresekwa high density suburb, Harare to understand the usefulness of including women in household solid waste management. The study used both qualitative and quantitative methods including focus group discussions, key informant interviews, structured questionnaire survey and observations . The main aim was to examine the usefulness of including women in solid waste management in Dzivaresekwa suburb. A sample of 113 Dzivaresekwa households was used. The study was based on the concept of women empowerment, where the rights-based approach and ecofeminism were used. The study found out that women and men defined solid waste differently. Inclusion of women in solid waste management was found to ensure proper sanitation behaviour would be observed by the community and contributions in cash, kind or labour would be availed. The study concluded that women were highly experienced in managing natural resources, bringing valuable knowledge that should be harnessed through bottom-up processes. Recommendations were that solid waste management required harnessing traditional knowledge and skills, particularly that of women.
SEX DIFFERENCES IN HEADACHE : IMAGING STUDIES

Recent findings—Recent functional MRI (fMRI) studies of the brain support the existence of anatomical and functional differences between men and women, as well as between participants with migraine and healthy controls. In addition to the naturally occurring changes in endogenous sex hormones over the lifespan (e.g. puberty and menopause), exogenous sex hormones (e.g. hormonal contraception or hormone therapy) also may modulate migraine. Recent data support the historical view of an elevated risk of migraine with significant drops in estrogen levels. In addition, several lines of research support that reducing the magnitude of decline in estrogen concentrations prevents menstrually related migraine (MRM) and migraine aura frequency.
Entrepreneurial Intention among Students of Selected Tertiary Institutions in Ondo State

ntrepreneurial intention (EI) is one of the major contributing factors to the Eformation, growth and development of entrepreneurship. It promotes selfreliance and brings about initiatives. Entrepreneurship on the other hand, has been considered as an engine of growth for economic growth and development of developed and emerging economies. However, a major issue of concern is the level of adoption of government policies on entrepreneurship education as well as entrepreneurship development centres stimulating the desires of students towards entrepreneurship. This study examined the entrepreneurial intention among students of selected tertiary institutions in Ondo State. This study employed survey research design. A sample was drawn from the Federal University of Technology, Akure (FUTA), Adekunle Ajasin University, Akungba Akoko (AAUA) and Achievers University, Owo (AUO). Data were collected for the study through the administration of structured questionnaires from three hundred and ninety six (396) students of which three hundred and eighty eight (388) were retrieved. Data analysis included descriptive and inferential statistics. The results from the regression analysis revealed that entrepreneurship education has a positive influence on entrepreneurial 2 intentions of students with R value of 0.731, p-value = 0.000 which revealed that 73% of the variation in entrepreneurial intentions is explained by variation in entrepreneurship education of students. Personality traits have positive influence on 2 entrepreneurial intentions of students with R value of 0.560, p-value of 0.000 which revealed that 56% of the variation in entrepreneurial intentions is explained by variation in personality traits of students. There was positive but weak relationship between demographic characteristics of students and their entrepreneurial intentions with correlation coefficient of r = 0.416 and p-value of 0.000. Therefore, rejecting the three null hypotheses. Policy recommendations were made as emanated from the study which includes making student entrepreneurship core missions of government agencies such as Small and Medium Enterprises Development Agency and Small Enterprise Finance Agency. It was concluded from these findings that previous entrepreneurial experience, demographic characteristics, participation in entrepreneurship education and personality traits can have a positive impact on an individual's intention to be self-employed.
Contact and change in Central Salish words for salmon *

Within comparative Salish linguistics, the problems of frequent irregular sound correspondences and overlapping lexical isoglosses are well known. In this paper, the possible effects of contact on lexical change within the Central Salish branch are examined, focusing on the semantic domain of words for salmon. This builds on previous work by Thom Hess, Donna Gerdts, Aert Kuipers, and others, studying lexical diffusion within the Salish family. All cognate sets shared by two or more languages are listed, and comments on phonological form and meaning are given. The geographic distribution and phonological irregularity of certain sets imply a mechanism of diffusion which has likely been ongoing for most of Central Salish history, and suggest that alternatives to the traditional tree model are required to account for these processes of change.

Biochemical role of wheat germ oil on biomarkers of oxidative stress and inflammatory response in a rat model of endotoxemia

The main objective of this study was to investigate the protective effect of wheat germ oil on oxidative stress induced by endotoxin in rats. Fourty five male rats divided into three equal groups of (15 each). Group I (control): rats received no drugs. Group II (Endotoxin group): rats injected intraperitoneally (i.p) with a single dose of endotoxin (200 mg/Kg b.wt). Group III (wheat germ oil protected group): rats pretreated with wheat germ oil (270 mg/kg b.wt./day) orally for 21 day then injected with a single dose of endotoxin (200 mg/Kg b.wt). Blood samples for serum separation and liver tissues were collected from all animal groups after 1 and 3 hours from the onset of endotoxin injection. Serum tumor necrosis factoralpha (TNF-α), interleukin-6 (IL-6), L-Malondialdehyde (L-MDA), Nitric oxide (NO) and sialic acid, in addition to liver tissue superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), myeloperoxidase (MPO), reduced glutathione (GSH),Glutathione S-transferase (GST) and LMalondialdehyde (MDA) were determined. The obtained results revealed that, endotoxemia could potentially increase serum TNF-α, IL-6, L-MDA concentrations and markedly decrease NO and sialic acid levels. Moreover, SOD, CAT and MPO activities and GSH concentration in liver tissues were significantly decreased. Pretreatment with wheat germ oil decreased LPS-triggered pathogenic responses and prevented the increase of TNF-α, IL-6 and L-MDA. Moreover, pretreatment with wheat germ oil in endotoxin injected rats responsible for the protection of membrane polyunsaturated fatty acids against lipid peroxidation by increasing the activity of liver tissue antioxidant enzymes GST, SOD and CAT. From the obtained results it could be concluded that, wheat germ oil protects against lipid peroxidation, oxidative stress and decrease the inflammatory response induced by endotoxin injection
Future English teachers ' attitudes towards EIL pronunciation

English has become the world's international language, used for international communication mostly among non-native speakers of other languages and 80 percent of all the English teachers around the world are nonnative Englishspeaking (NNES) teachers (Canagarajah, 1999). Therefore, there is a growing need to investigate the EIL (English as an International Language) movement from non-native pre-service or in-service teachers' point of view. This study examined future English teachers' attitudes towards teaching pronunciation within an EIL perspective. Questionnaires and semi-structured interviews with senior students revealed that native-speaker English is regarded as the correct model in English language teaching (ELT). The implications of the findings on the propagation of native speaker norms as the teaching model and the status of ELF and its reflections on ELT in Turkey are discussed.
FROM HIGH MAGNETIZATION FERROFLUIDS TO NANO-MICRO COMPOSITE MAGNETORHEOLOGICAL FLUIDS : PROPERTIES AND APPLICATIONS

Recent results are reviewed on the synthesis and properties of high magnetization ferrofluids and ferrofluid based magnetorheological (MR) fluids. Structural characteristics at nanometer level, colloidal behavior in specific environments, magnetic and flow behavior of a large variety of ferrofluids and some newly developed nano-micro composite magnetizable fluids were evaluated by transmission electron microscopy (TEM/HRTEM), X-ray photoelectron spectroscopy (XPS), dynamic (DLS) and static light scattering (SLS), small angle neutron scattering (SANS), small angle X-ray scattering (SAXS), vibrating sample magnetometry (VSM), Mössbauer spectroscopy, rheo-magnetorheometry, chemiluminiscence (CL), and differential scanning calorimetry (DSC). The paper is focused mainly on the synthesis and properties of long-term colloidal stability and high magnetization sealing fluids and of ferrofluid based magnetorheological fluids with improved kinetic stability and high MR response.
Vaginal Candidiasis-The Known Opportunistic Fiend in Developing Countries

BackgroundVaginal yeast infections, also known as candidiasis, are a common female condition. A healthy vagina has bacteria and some yeast cells,but when the balance of bacteria and yeast changes, the yeast cells can multiply. This causes intense itching, swelling, and irritation. Treating a vaginal yeast infection can relieve symptoms within a few days. In more severe cases, it may take up to two weeks. Vaginal yeast infections aren’t considered a sexually transmitted infection (STI). Sexual contact can spread it, but women who aren’t sexually active can also get them. Aims and ObjectivesTo study the prevalence of candidiasis in Gwalior, role of cervicovaginal smear examination in it’s diagnosis and spectrum of disease in various age groups. MethodologyThis is a retrospective study. A total number of 5000 cervicovaginal smear which were reported in Department Of Pathology, G.R Medical College Gwalior, were included in the study. The data of cervicovaginal smear examination reported were retrieved, compiled and analyzed. Results and ConclusionsOut of 5000 cervicovaginal smears examined, 280 (5.6%) females were positive for candidiasis, with highest incidence found in women aged between 21-30 years (37.5%). Cervicovaginal smear examination with Leishman-Giemsa staining would help in early detection of candidiasis which can prevent various complications in women chiefly in the reproductive age group.

Studies of Alpha Clustering in Nuclei

In this thesis, I present theoretical studies for the possible existence of alpha clustering in nuclei. During my PhD work, I was doing calculations based on a new Quantum Molecular Dynamics like model originally developed by Dr hab. Zbigniew Sosin in Fortran language. I wrote a C++ version of this model with the inspiration from Fortran code. The interaction between nucleons are described by a new form of Equation of State (EOS) of nuclear matter, which depends on both spins and isospins. For the finite nuclei, the Coulomb interaction between protons and the surface effects are also taken into account. In the preliminary step, we calculated the ground state properties of nucleus by the minimization of its total energy, which will be a starting point for future nuclear dynamics calculations. The calculation results are compared with the experimental binding energy, r.m.s. charge radius and the radial density distribution of nuclei. Also it is presented a systematic study of binding energy curve based on the extended Bethe assumption on number of alpha-alpha bonds. Streszczenie W niniejszej rozprawie przedstawiam badania teoretyczne dotyczące ewentualnego istnienia struktur alfowych w jądrach atomowych. W trakcie pracy doktorskiej, robiłem obliczenia oparte o nowy model typu Kwantowej Dynamiki Molekularnej, pierwotnie opracowany przez dr hab. Zbigniewa Sosina w języku Fortran. Napisałem wersję C++ tego modelu bazując na kodzie Fortran. W modelu interakcja między nukleonami opisana jest przez nową formę równania stanu (EOS) materii jądrowej, która uwzględnia zarówno spiny jak i izospiny nukleonów. Model uwzględnia również, oddziaływanie kulombowskie między protonami i efekty powierzchniowe dla skończonych jąder. We wstępnym etapie obliczyliśmy właściwości stanu podstawowego jądra poprzez minimalizację jego całkowitej energii. Rachunek ten będzie punktem wyjścia dla przyszłych obliczeń dynamiki jądrowej. Wyniki obliczeń porównano z eksperymentalną energią wiązania, średnim promieniem kwadratowym rozkładu ładunku i radialnym profilem gęstości masy jąder. Ponadto w pracy zaprezentowano wyniki badań nad krzywą energii wiązania jąder w oparciu o rozszerzoną hipotezę Bethe na temat liczby wiązań pomiędzy cząstkami alfa-alfa.

SYNTHESIS CHARACTERIZATION , OPTICAL AND ANTIBACTERIAL STUDIES OF Co-DOPED SnO 2 NANOPARTICLES

This study was involved to synthesize, characterize and investigate the antimicrobial properties of Cobalt-doped tinoxide (Co-doped SnO2) nanoparticles. Cobalt-doped tinoxide (Co-doped SnO2) nanoparticles were prepared by using a simple and cheap co-precipitation method. The synthesized and Cobalt-doped tinoxide (Co-doped SnO2) nanoparticles were characterized by using different characterization techniques i.e. Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) analysis, and Ultraviolet-visible (UV-Vis) spectroscopy. The antimicrobial activity of the synthesized Cobalt-doped tinoxide (Co-doped SnO2) nanoparticles was carried by agar well diffusion method against both Gram-negative (Escherichia coli) and Gram-positive bacteria (Bacillus subtilis). Results from XRD, SEM, EDX and UV-Vis analyses demonstrated successful synthesis of Co-doped SnO2 nanoparticles as seen in their tetragonal structures. The average grain size of the synthesized nanoparticles was found to be 24.8 nm. The optical properties were studied by measuring the energy band gap and were found 1.50 eV for un-doped SnO2 nanoparticles, and it decreases to 1.48 eV for Co-doped nanoparticles. Co-doped SnO2 nanoparticles were exhibited the significant and maximum antibacterial activity against both bacterial strains with the zone of inhibition (ZOIs) of 16 ± 0.8 mm and 22 ± 1.6 mm for Escherichia coli (E.coli) and Bacillus subtilis (B. subtilis) respectively. Co-doped SnO2 nanoparticles showed good activity against both Gram-negative and Gram-positive bacteria confirming these as future broad spectrum antibacterial. Thus, the preparation is a good candidate for further development into therapeutic formulations.
Novel Three-Phase AC-DC-AC Sparse Matrix Converter Part I: Derivation, Basic Principle of Operation, Space Vector Modulation, Dimensioning

A novel three-phase AC-DC-AC Sparse Matrix Converter (SMC) having no energy storage elements in the DC link and employing only 15 IGBTs as opposed to 18 IGBTs of a functionally equivalent conventional AC-AC matrix converter (CMC) is pro- posed. It is shown that the realization effort could be further reduced to only 9 IGBTs (Ultra Sparse Matrix Converter, USMC) in case the phase displacement of the fundamentals of voltage and current at the input and at the output is limited to ±π/6. The dependency of the voltage and current transfer ratios of the systems on the operating parameters is analyzed and a space vector modulation scheme is described in combination with a zero current commutation proce- dure. Furthermore, a safe multi-step current commutation concept is treated briefly. Conduction and switching losses of the SMC and USMC are calculated in analytically closed form. Finally, the theoretical results are verified in Part II of the paper by digital simulations and results of a first experimental investigation of a 10kW/400V SMC prototype are given.
