During spermiogenesis the spermatid nucleus is elongated, and dramatically reduced in size with protamines replacing histones to produce a highly compacted chromatin. After fertilisation, this process is reversed in the oocyte to form the male pronucleus. Emerging evidence, including the coordinated loss of the nuclear lamina (NL) and the histones, supports the involvement of the NL in spermatid nuclear remodelling, but how the NL links to the chromatin is not known. In somatic cells, interactions between the NL and the chromatin have been demonstrated: LEM-domain proteins and LBR interact with the NL and respectively, the chromatin proteins BAF and HP1. We therefore sought to characterise the lamina-chromatin interface during spermiogenesis, by investigating the localisation of six LEM-domain proteins, two BAF proteins and LBR, in human spermatids and spermatozoa. Using RT-PCR, IF and western blotting, we show that six of the proteins tested are present in spermatids: LEMD1, LEMD2 (a short isoform), ANKLE2, LAP2β, BAF and BAF-L, and three absent: Emerin, LBR and LEMD3. The full-length LEMD2 isoform, required for nuclear integrity in somatic cells, is absent. In spermatids, no protein localised to the nuclear periphery, but five were nucleoplasmic, receding towards the posterior nuclear pole as spermatids matured. Our study therefore establishes that the lamina-chromatin interface in human spermatids is radically distinct from that defined in somatic cells. In ejaculated spermatozoa, we detected only BAF and BAF-L, suggesting that they might contribute to the shaping of the spermatozoon nucleus and, after fertilisation, its transition to the male pronucleus.

Published: July 2017

A relationship among total organic carbon content determined by ignition loss (LOI) and DUMAS combustion methods, were perfomed in evergreen Andean eyebrow forest soils, southwestern zone of Sangay National Park- Ecuador, where three conglomerates were established as follows: (C) with five plots (P) with plots of 20 x 20 m. In each plot, five digging trenches and four soil samples were carried out at different depths: 0-10, 10-20, 20-30 and> 30 cm, respectively. It is observed that the amount of total organic carbon obtained by the DUMAS and LOI method (R2 = 0.99) does not differ significantly. However, the DUMAS total organic carbon determination methodology showed greater precision with regard to LOI, thus becoming a good alternative to be used as a reference method. In addition, the operability in the laboratory is reflected in the reduction of time and optimization of the human resource. The correlation level shows a low level of significance among these methods, the variation is greater in the DUMAS method (3.38%), due to the analyzed volumes of the samples and the auxiliary equipment level of precision.

Published: July 2017

‘Cleopatra’ tangerine (Citrus reshni hort. ex Tanaka) is a commonly used rootstock in the piedmont of Meta department, Colombia for establishing of commercial citrus orchards. Have allowed a late production entrance rootstock and produced big plants when grafted with tangelo ‘Minneola’ (C. reticulata Blanco x C. paradise Macf), decreasing the productive efficiency in plants and hard crop practices. The evaluated performance were as follows:  tree size, productive efficiency and fruit quality of tangelo ‘Minneola’ grafted in six rootstocks. It found that the cumulated production of 11 years was better with Citrumelo ‘Swingle’ (Citrus paradisi Macf. × Poncirus trifoliata (L.) Raf) with 1388.3 kg tree-1, followed by ‘Cleopatra’ (Citrus reshni hort. ex Tanaka) with 893.2 kg.tree-1, in last place was ‘Carrizo’ (Citrus sinensis Osb. × Poncirustrifoliata (L.) Raf) with 182.9 kg tree-1. The other rootstocks, had a medium production. The greatest height and canopy value, was found with ‘Cleopatra’ without significant differences with Citrumelo ‘Swingle’. In fruit quality no significant differences occurred.

Published: July 2017

In order to evaluate the effect of a growth promoter on the productivity performance and seed-quality in bean (Phaseolus vulgaris L.) crops, two experiments were carried out, one in the field and under controlled conditions. In the field experiments, a Latin square design was used for four treatments as follows: control, 0.5, 0.8 and 1.0 l.ha-1, respectively, where yield components were evaluated. The seeds used in the controlled conditions experiment were from prior trials, in a totally randomized design, at the dosages above mentioned. Seed germination and seedling growth were evaluated. In the field experiments, the product had a stimulating effect on the production. The highest yields were reached with the 0.8 and 1.0 l.ha-1 dosages in number 1, with values of 3.09 and 3.02 t.ha-1, and in number 2, the treatment with the best results was 1.0 l.ha-1, with a yield of 2.07 t.ha-1. In germination, there were significant differences among variables only in the first assessment at three days after planting. The best performance in seedling growth and in dry matter production was the treatment with seeds from the 0.5 l.ha-1 dosage in experiment 1. In addition, in number 2, performance among variables was similar. Therefore, VIUSID agro improved the bean yield performance and did not affect later seed germination nor initial seedling growth.

Published: July 2017

The antagonistic effectiveness of native strains of Trichoderma spp. on Fusarium oxysporum f. sp. pisi. in vitro, greenhouse and field conditions, were evaluated. In laboratory conditions, the antagonistic capacity of 12 strains of Trichoderma spp., strains C2, C7, C12 and C21, exhibited a better behavior measured by the following variables: inhibition halo and mycelial growth. In greenhouse conditions, the four strains, which showed the best in vitro antagonistic behavior were evaluated using a DIA experimental design with factorial arrangement for three factors which corresponded to strain, concentration and dose. The results of this evaluation, showed that strains C12 and C21 at doses of 20 mL, and at concentrations of 108 and 106 conidia.mL-1, respectively. The best antagonistic response was determined by variables as follows: plant height, fresh root weight and incidence. Under field conditions, the evaluations were carried out in the municipalities of Ipiales, Pupiales and Gualmatán, in the Department of Nariño, Colombia. In each location, a BCA experimental design was used with four treatments and five replicates, treatments were as follows: C12 strains at 108 concentration, C21 at 106 concentration, chemical control and absolute control. In Gualmatan location, C12 and C21 strains, showed no antagonistic capacity, whereas in Ipiales and Pupiales locations, strain C12, presented a lower incidence of F. oxysporum than the control, but with no effect on yields. In Pupiales location, C21 strain surpassed in performance to the control treatment, even though the two treatments had similar incidence.

Authors: Loeza-Corte Juan Manuel , Díaz-López Ernesto
Published: July 2017

Calla (Zantedeschia aethiopica (L.) K. Spreng), is a cut flower which had obtained importance in recent years, but postharvest handling is limited. Thus, in order to know the fluorescein concentration effect and pH of pulse solution on inflorescences calla postharvest, were evaluated in Teotitlan de Flores Magon, Oaxaca-Mexico, four fluorescein concentrations (0, 20, 40 and 60 %, respectively) and two pH levels (acid and alkaline) in a completely randomized design with factorial arrangement, having a total of 24 experimental units, which was established by vase life and calla inflorescence with white spathe color, immersed in a fluorescein solution adjusted as appropriate at acidic or alkaline pH, where response variables were as follows: vase life, water consumption, stem diameter, absorption fluorescein stem base and fluorescein vertical absorption by floral scape. Results indicates the increased vase life is achieved at alkaline pH by fluorescein addition of 20, 40 and 60 %, respectively. Likewise, the higher water consumption is achieved at this pH. From this research, we can conclude fluorescein can affect the calla physiology for increasing vase life.
Effect of plantain (Musa paradisiaca L. cv. Dominico Harton) peel flour as binder in frankfurter-type sausage
Authors: Rosero Chasoy Gilver , Serna Cock Liliana
Published: July 2017

Agroindustrial residues such as plantain (Musa paradisiaca L. cv. Dominico Harton) peel have functional properties, which made them suitable for use as a food ingredient. The aim of this research was to evaluate plantain peel flour (PPF) as a binder in the production of frankfurter- type sausage. Five formulations were prepared in which wheat flour (WF) was replaced by PPF as follows: 25%, 50%, 70% and 100%, respectively. Once the sausages are obtained, the water retention capacity (WRC), emulsifying stability (ES), and pH, were evaluated. When comparing treatments with the control sample, it was found that replacing up to 50% of WF by PPF, significantly increased WRC by 7.5%. When replacing 25%, Es, there were no statistically significant changes among treatments. When replacing 100%, the product pH, was significantly decreased. The results indicated, the sausages made with 50% of PPF, retain the formulation water, which is why the PPF has potential for this type of sausage manufacture. PPF could replace WF up to 25% in the frankfurter formulation, without affecting ES and pH and favoring WRC.

Authors: Torres Bazurto Jaime , Sanchez Jaiver Danilo , Cayon Salinas Daniel Gerardo
Published: July 2017

This research determined the effect of four nitrogen (N) doses on the nutritional behavior of (N), potassium (K), phosphorus (P), calcium (Ca) and magnesium (Mg), respectively, in banana Williams, during five plant development stages and two productive cycles. The treatments were as follows: 1) absolute control, 2) 0 N, 3) 161 kg N ha-1, 4) 321.8 kg N ha-1 and 5) 483 kg N ha-1, respectively. A multivariate approach of the differences among cycles was used to adjust the models and eliminate their individual effect, with a randomized complete block design with repeated measurements over time. There were significant differences among plant development stages, with an increase in nutrient accumulation in the banana plant, there were no differences among treatments or blocks, nor in the interaction block by treatment, but the dose of 321.8 kg of N, exhibited a fructification increase in terms of N accumulation, harvest was exceeded by the dose of 483 kg of nitrogen, Ca and Mg, were the other nutrients, which showed effect at the dose of 483 kg of N but increasing only to harvest. It was concluded that high doses of nitrogen showed a trend to increase nutrient accumulation during the development of the banana plant, but especially until fructification, with the exception of Ca and Mg, which achieved the greatest accumulation in harvest.

Published: July 2017

The contribution of Colombia to global emissions of greenhouse gases (GHGs) is low (0.37%); from this percentage, 38% is attributed to agriculture. There are few studies on GHGs emissions at the regional level for agriculture. Therefore, the aim of this research is to estimate dynamically GHG and carbon footprint produced by cattle in the department of Valle del Cauca, Colombia. GHG estimates were established as follows: Tier II of IPCC methodology (2006), and population trends, which were simulated using dynamic system. According to the departmental livestock inventory in recent years (2009-2015), average emissions were 673 million of CO2eq. year-1, with emissions intensity (EI) of 5.58 kgCO2eq.kg.milk-1 and 3.54 kgCO2eq.kgmeat-1. Simulating the behavior of the bovine population (2016-2035), based on historical trends, the number of animals and emissions tended to reduce. The simulated EI was in 4.1 - 4.2 kgCO2eq.kg.milk-1 and 3.7 – 3.9 kgCO2eq.kg.meat-1. Increasing birth rates (83 to 90%), lower age at first birth (34 to 30 months), increased milk production per cow per day (5.33 to 10 kg), increased production of milk and meat in 100 and 4 million kg per year, respectively; with decrease in EI of 1.4 for milk and 2 units for meat. This study showed selecting efficient animals (productively and reproductively), can produce more animal protein with less carbon footprint.
Comicidad y perversión: dos enantiómeros
Authors: González García Ignacio
Published: July 2017

Esta investigación —realizada sobre la base de las nociones freudianas de perversión y de lo cómico, y utilizando los conceptos lacanianos de goce y falta—: a) propone y justifica la tesis de que lo cómico y el humor son formas de perversión; b) muestra la relación estructural de los modos de lo cómico con el sadismo y el masoquismo e ilustra la tesis con las categorías de Gilles Deleuze; c) propone una teoría de sus relaciones basada en la noción de quiralidad y formula que los dos conceptos son eniantómeros con respecto al sentido de relación entre la propia falta y la del Otro.
Muerto de la risa: el humor y la puntuación
Authors: Guerrero Omar
Published: July 2017

A partir de los atentados que sacudieron a Francia y a todo Occidente el 7 de enero de 2015, ¿cómo entender la articulación entre el “humor sin límites” de los dibujantes asesinados y el “amor sin límites” de los terroristas implicados? Más allá de lo que Freud pudo anticipar sobre el humor, la enseñanza de Lacan nos permite situar este mecanismo inconsciente, incluso, en la progresión de la cura. Cuando el humor surge… en serio.
Metafísica de la risa: Freud, Lacan, Bataille
Authors: Lippi Silvia
Published: July 2017

Analizaremos la noción de la risa a través del aporte de Freud, Lacan y Bataille. La risa que se desencadena por el humor, el chiste y lo cómico, se muestra como una articulación particular del lenguaje y del goce, como efecto de la palabra sobre el cuerpo. Si el chiste es un significante que se expresa como formación del inconsciente estructurado como un lenguaje, la risa es un goce: un goce del cuerpo en relación con lo inconsciente real. Nos detendremos en la articulación entre ley y transgresión en el chiste, tanto como en la cuestión del sentido —dirección— y del no-sentido, que le compete. Veremos también cómo la risa apunta a la castración, pero se trata de una castración que no es del orden de lo insoportable, porque el encuentro con esta se constata a través de la risa del cuerpo, que al mismo tiempo separa al sujeto de su yo alienante y destructor.

Published: July 2017

A method was developed for the preparative separation of two alkaloids from the crude extract of the radix of Rauvolfia verticillata (Lour.) Baill. in a single run. The two-phase solvent system composed of petroleum ether–ethyl acetate–methanol–water (5:5:2:8, v/v), where triethylamine (40 mmol/L) was added to the upper organic phase as the stationary phase and hydrochloric acid (10 mmol/L) was added to the lower aqueous phase as the mobile phase, was selected for this separation by pH-zone-refining counter-current chromatography (PZRCCC). For the preparative separation, the apparatus was rotated at a speed 850 rpm, while the mobile phase was pumped into the column at 2 mL/min. As a result, 112 mg of reserpine and 21 mg of yohimbine were obtained from 3 g of crude extract in a single run. The analysis of the isolated compounds was determined by high-performance liquid chromatography (HPLC) at 230 nm with purities of over 91.0%, and the chemical identification was carried out by the data of electrospray ionization–mass spectrometry (ESI–MS) and nuclear magnetic resonance (NMR) spectroscopy. The technique introduced in this paper is an efficient method for preparative separation of reserpine and yohimbine from devil pepper radix. It will be beneficial to utilize medicinal materials and also useful for the separation, purification, and pharmacological study of Chinese herbal ingredients.

Ageing and cyclic behaviour of axially loaded piles driven in chalk
Authors: Buckley R. M. , Jardine R. J. , Kontoe S. , Parker D. , Schroeder F. C.
Published: July 2017

This paper reports a programme of static and cyclic loading tests on seven open steel tubes driven in low- to medium-density chalk at a well-characterised test site, describing their response to driving, ageing in situ and loading under both static and cyclic conditions. Back analysis of dynamic monitoring identifies the distributions of notably low shaft resistances that develop during installation, showing that these depend strongly on the relative pile tip depth (h/R). The shaft capacities available to ‘virgin’ piles are shown to increase markedly after driving, following a hyperbolic trend that led to a fivefold gain after 250 days. Pre-failed piles do not follow the same trend when re-tested. Pile exhumation confirmed that driving remoulded the chalk, creating a puttified zone around the shaft. Excess pore water pressure dissipation, which is likely to have been rapid during and after driving, led to markedly lower water contents close to the shaft. Axial cyclic testing conducted around 250 days after driving led to a range of responses, from manifesting stable behaviour over 1000 cycles to failing after low numbers of cycles after developing sharp losses of static capacity. The dependence of permanent displacement on the cyclic loading parameters is explored and characterised. The experiments provide the first systematic study of which the authors are aware into the effects of undisturbed ageing and cyclic loading on previously unfailed piles driven in chalk. Potential predictive tools may now be tested against the reported field measurements.
Contract structure for nuclear power projects
Authors: Bird Raymond , Wearne Stephen
Published: July 2017

The UK government chose an unusual contract structure for the procurement of their programmes of civil nuclear power projects. British manufacturing and construction companies were invited to form consortia to compete for ‘turnkey’ contracts to design and supply complete power stations. The government continued with this structure until late in their second programme of projects. The results met the objective of national independence in power supply, but at a cost. This paper reviews the structure used in the UK, its evolution through two programmes of projects and lessons to be learned for new projects. The paper draws on published material, official papers, private records and reports from other countries. The most important lessons are that project sponsors should give rigorous attention to the choice of contract structure when initiating such major projects and that the structures open to them are not unique to their industry.
El deseo de acceso y equidad en la educación matemática
Authors: Valero Paola
Published: July 2017

La idea de que el fracaso en las matemáticas es un problema para la democracia y la equidad debe entenderse como parte de una configuración histórica donde el logro de los individuos y la población se conecta con el desarrollo de capital humano y el progreso social y económico. El deseo de una población con más capacidades matemáticas va de la mano de la generación de mecanismos de ordenación y clasificación de la población y la in(ex)clusión con relación al éxito/fracaso en las matemáticas escolares. La investigación internacional en educación matemática ha abordado este problema desde distintas posiciones teóricas. Dos de ellas se identifican: la posición del empoderamiento supone que las matemáticas transfieren sus atributos de poder a quienes las aprenden, o bien por sus características intrínsecas, o por sus aplicaciones, o por su carácter crítico. La posición de la desigualdad supone que las matemáticas como formas de conocimiento en sí o como parte de las prácticas escolares se entrelazan con mecanismos de clasificación social de acuerdo con otras categorías, como la habilidad, el género, el lenguaje, etc. Las tensiones que emergen en el campo de la educación matemática por la co-existencia de esta diversidad de visiones llama a tomar una posición ética y política sobre qué posibilidades hay para la investigación y la práctica.

Published: July 2017

Este artículo analiza dos extractos tomados de dos capítulos de dos libros de texto en los cuales se identificaron dos patrones textuales: (1) problema-solución-evaluación y (2) delito-defensa. El estudio, realizado con los principios del análisis de género aplicado (Hoey, 2001) y la caracterización del discurso jurídico propuesta por Lisina (2013), permitió acuñar el segundo caso, delito-defensa, como un nuevo patrón. Así, este puede ser considerado un aporte tanto para la literatura relacionada con los patrones textuales como para el campo de la enseñanza del Inglés con Fines Específicos, ife. Además, el artículo presenta una serie de actividades basada en el enfoque de aprendizaje por tarea (Willis, 1996), organizadores gráficos, vocabulario técnico y el análisis llevado a cabo. Esta tarea ha sido diseñada para un curso de ife de lectura de textos académicos en inglés nivel ii en la Universidad del Valle en Cali, Colombia.
Elaboración y validación de un cuestionario de Preocupaciones Profesionales sobre la Enseñanza de la Biología (PPEB)
Authors: Ravanal Moreno Eduardo , López-Cortés Francisco
Published: July 2017

El artículo da cuenta de la elaboración y la validación de un cuestionario denominado Preocupaciones profesionales sobre la enseñanza de la biología (PPEB), el cual se sustenta en los estados de desarrollo profesional centrados en la enseñanza. Reconocemos que la representación intrapersonal sobre un asunto de enseñanza no es equivalente en los profesores; de ahí la importancia de un instrumento que permita su exploración. La construcción del instrumento se sustenta en los aportes de Kugel (1993), quien centra su atención en la enseñanza de la biología. El uso del cuestionario PPEB permitiría identificar las inquietudes profesionales sobre la enseñanza de la biología, las cuales se c onstituyeron en andamios de reflexión profesional para construir dificultades de enseñanza y potenciales problemas prácticos de enseñanza según la representación intrapersonal del profesor. En ese sentido, reconocemos tres espacios para el desarrollo profesional: el de preocupación profesional, el de dificultad profesional y el de problema de enseñanza, de los cuales el eje catalizador es el primer espacio, y, por tanto, el eje que dinamiza cualquier programa de desarrollo focalizado en la mejora de la enseñanza.

Representaciones culturales en la enseñanza de las ciencias. una respuesta con base en las opiniones de estudiantes de licenciatura en biología
Authors: Robles-Piñeros Jairo , Maia Barboza Ana Caroline , Costa Santos Geilsa
Published: July 2017

Por mucho tiempo, dentro de la historia de la educación escolar se asumió que las aulas de clase eran espacios homogéneos, constituidos bajo la concepción imperante de que dentro del proceso de enseñanza de las ciencias solo se puede representar la cultura científica. De esta forma, los discursos de los profesores se ven permeados por la idea de una superioridad epistemológica del discurso científico a la hora de enseñar ciencias. El presente trabajo se basa en el análisis de las opiniones de estudiantes de licenciatura en Biología de la Universidad Estatal de Feira de Santana (UEFS), de Bahía/Brasil, sobre el concepto de cultura y representaciones culturales, y su relación con el proceso de enseñanza de las ciencias. El trabajo se desarrolló con estudiantes de tercer semestre del programa Licenciatura en Ciencias Biológicas de la UEFS; es una investigación de corte cualitativo que usó el proceso de análisis de contenido de respuestas escritas mediante el sondeo con cuestionario de pregunta abierta, aplicado al inicio del curso. Las opiniones de los licenciandos en Biología permiten observar una visión y una conceptualización amplias de la noción de cultura, así como el papel de las representaciones culturales dentro del aula de clases en el proceso de enseñanza de las ciencias. Se considera este trabajo como apoyo al proceso de ampliación de las discusiones sobre la relación entre educación, ciencia y cultura en la formación de profesores de ciencias.

Authors: Greene Dorothy , Mullins Mary , Baggett Paul , Cherry Donna
Published: July 2017

Little has been published regarding BSW students' perceived stress, coping self-efficacy, and self-care. A preexperimental study, with one qualitative question, was used to determine the effects of a self-care course on students' perceived stress scores (PSS), coping self-efficacy scores (CSES), and subjective experiences. Nineteen undergraduate students participated. Mean age of participants was 25, 90% were female, and most were Caucasian. The average CSES was 161.42 (SD=41.57) at pretest and 180.72 (SD=34.97) at posttest. A statistically significant difference in mean scores was found (t=−2.109, p=.05). The average PSS was 17.58 (SD=8.50) at pretest and 14.83 (SD=5.607) at posttest. Students' subjective experiences with the course were positive, and 79% noted that their understanding of self-care changed. Despite the small sample and lack of diversity, the study's contribution is noteworthy. To the authors' knowledge, this is the first study to examine the impact of a 3-credit course on self-care for BSW students.

Authors: Rout Anima , Panda Rajendra K. , Mishra Vedvyas , Parida Prasant , Mohanty Srikant
Published: July 2017

Background: Globally cancer is the leading cause of morbidity and mortality with annual death rate of 12%. According Indian Council of Medical Research, more than 1300 Indians die every day due to cancer. Chemotherapy is one of the multimodal approaches for treatment of cancer and regimens are much complex and cancer patients are more susceptible to adverse drug reaction with little tolerance due to diminished immunity. The present study was done to evaluate the prevalence of various adverse drug reactions with different cancer chemotherapy regimens, their nature and severity as well as their causality assessment as per WHO scale.Methods: This prospective observational study was conducted from July 2015 to June 2016. Patients receiving cancer chemotherapy from regional cancer centre, Cuttack were observed during the study period for the adverse drug reactions. Those ADRs were analysed for causality assessment, severity and preventability.Results: It was observed that after the initiation of chemotherapy, ADRs were observed in 92 (88.46%) patients. Among these 329 observed ADRs, during the study period, female predominance was observed in the age group 51-60yrs. Most common ADRs observed were nausea and vomiting 57 (17.37%), alopecia 46 (13.98%) and neutropenia 38 (11.55%). ADRs were most commonly seen with the haematological systems (37.68%) followed by gastrointestinal system amounting 25.22% of the total ADRs. Platinum Compound (58.35%), followed by antibiotics, antimetabolites, were the most common group of drugs causing different adverse drug reactions. On causality assessment, as per WHO-UMC criteria 68.38% were probable and 31.62% ADRs were possible. Severity assessment showed majority of the ADRs were moderate 228 (69.31%) followed by mild 67 (20.36%) and severe 34 (10.33%). It was observed that majority 212 (64.45%) of the ADRs were not preventable, 72 (21.88%) were definitely preventable and 45 (13.67%) were probably preventable.Conclusions: Cancer chemotherapy has definitely improved the quality of life, but associated ADRs need early diagnosis, prompt management and routine reporting. Thus, pharmacovigilance will definitely reduce morbidity and mortality, so also the financial burden for the patients and society.

Authors: D. Sowmya , S. Anitha
Published: July 2017

Background: A true definition of polycystic ovarian syndrome involves a blending of the morphological and histological ovarian changes with endocrine abnormalities associated with these changes. Objective of present study was to detect the differences among women with PCOS and without PCOS.Methods: Twenty-five subjects with PCOS were included in the study on first cum first basis and twenty-five non PCOS subjects just next to each PCOS cases were included as control group.Results: Mean age of PCOS and Non PCOS subjects were 42.68 and 43.88 years respectively. Sixteen percentage of PCOS were from higher socio-economic status, which was statistically significant. PCOS subjects had 96% hirsuitism, 48% acne, 4% heavy voice and breast atropy which was also statistically significant.Conclusions: Women with PCOS have a hormonal imbalance and metabolism problems that may affect their health and fertility, we found PCOS subjects are more in urban population with strong family history. Lifestyle modification and dietary modification helps for the long-term health prognosis. women who are at risk of PCOS to be educated and managed for the continuing health risk and planned potential therapeutic strategies. Further research has to look into possibility of genes linked into PCOS.

Convergence and Integrability of Series with Monotone Decreasing Coefficients by Chrestenson - Levy Systems
Authors: Episkoposian S. A. , Saghatelyan T. M.
Published: July 2017

In this paper we consider problems of convergence and integrability of series with monotone decreasing coefficients by Chrestenson - Levy systems. In particular we generalize some results, known for classical Walsh systems. Interest in questions arises due to a rapidly developed greedy algorithm in recent years, where in particular the important role played a representation of functions by series with monotone coefficients.
A New Class of Functions Suggested by the Generalized Basic Hypergeometric Function
Authors: Chudasama Meera H. , Dave B. I.
Published: July 2017

We introduce an extended generalized basic hypergeometric function rΦs+p in which p tends to infinity together with the summation index. We define the difference operators and obtain infinite order difference equation, for which these new special functions are eigen functions. We derive some properties, as the order zero of this function, differential equation involving a particular hyper-Bessel type operators of infinite order, and contiguous function relations. A transformation formula and an l-analogue of the q-Maclaurin's series are also obtained.

Published: July 2017

In this paper, we correct the contractive condition of Manro and Kang [16] and prove some common fixed point theorems for four faintly compatible mappings using subsequential continuous mappings in Intuitionistic Fuzzy metric spaces. We also provide an example in support of our main result. Our results improve and generalize the results of Manro and Kang [16].
Integral Closure of Noetherian Domains and Intersections of Rees Valuation Rings, (I)
Authors: Kemp Paula , Ratliff, Jr. Louis J. , Shah Kishor
Published: July 2017

It is shown that the integral closure R' of a local (Noetherian) domain R is equal to the intersection of the Rees valuation rings of all proper ideals in R of the form (b, Ik)R, where b is an arbitrary nonzero nonunit in R and the Ik are an arbitrary descending sequence of ideals (varying with b and with Ik ⊆ (Ik-1 ∩ I1k) for all k > 1, one sequence for each b). Also, this continues to hold when b is restricted to being irreducible and no two distinct b are associates. We prove similar results for a Noetherian domain.

Authors: Zhao Feng-Zhen
Published: July 2017

Let {Tn}n ≥ 0 and {Tn[1]}n ≥ 0 denote the tribonacci sequence and the sequence for the partial sum of {Tn}n ≥ 0, respectively. In this paper, we mainly investigate the log-concavity of Tn[1]}n ≥ 1 and the log-balancedness of some sequences involving Tn[1] . In addition, we discuss the monotonicity of some sequences related to Tn[1] .
Modelling Rayleigh Fading Channel in Underwater Wireless Communication Networks using Stochastic Network Calculus
Authors: Christhu Raj M. R. , Sukumaran Rajeev
Published: July 2017

A fundamental issue in underwater acoustic wireless channels is in analyzing the backlog and delay bounds that directly impacts the Quality of Service (QoS) performance in networks. Modern networks have been increasingly complex over the past few years in terms of control algorithms, applications and service expectations. Deterministic Networks Calculus (DNC) is not applicable to analyze QoS for the present day packet switched multimedia networks due to their inherently random behavior. To overcome these issues, Stochastic Network Calculus (SNC) has given rise to the optimism that it can emerge as an elegant mathematical modeling tool for assessing current network performance. In this work, we develop an underwater acoustic wireless channel subject to fading eects based on SNC that obtains Stochastic Arrival Curve (SAC) and Stochastic Service Curve (SSC). Using this we also derive the stochastic performance for delay and backlog bounds in underwater acoustic fading channel. The simulation performance analysis and bounds show that this method can provide guidelines for designing transmission strategies in underwater acoustic wireless channels.

(3) With V1, . . . , Vκ as in (2), V1 ∪ . . . Vκis a disjoint union of all of the Rees valuation rings of allof the M-primary ideals, and each M-primary ideal has at least one Rees valuation ring in each Vj .
The useful past in negotiation: Adolescents' use of history in negotiation of inter-group conflict
Authors: Goldberg Tsafrir
Published: July 2017

Much of the concern with young people's historical knowledge centres on factual attainment or disciplinary skills. However, relatively little attention is paid to the relevance that young people attribute to history and how they use the past, and various social representations of history,
to relate to the present. Research in this realm tends to emphasize the impact of collective memory narratives on individuals, rather than individuals' agency in using them. In this article, I will examine the ways 155 Jewish and Arab Israeli adolescents related the past to the present as
they discussed the Jewish–Arab conflict and its resolution. Discussants made diverse references to the past: from family history, via biblical allusions and collective memories, to formal, schooling-based historical documents. Individuals used these references to the past to negotiate
the present and future of inter-group relations. Furthermore, they made strategic use of references to others' narratives. Thus historical knowledge and collective narratives, which are usually perceived as constraining and structuring learners' perceptions, can be seen as repositories of
resources and affordances.
