Влияние температуры на скорость расслоения расплавов Sn-Pb в капиллярах
Authors: Boosov Nikita S. , Ouglev Nikolai P. 
Published: March 2019

Проведено исследование влияния температуры на скорость процесса расслоения металлического расплава олово-свинец в наклонном стеклянном капилляре. Основной целью исследования является установление механизма расслоения металлов. Температура считается одним из основных параметров молекулярно-кинетического движения атомов конденсированной системы частиц в жидком состоянии. Скорость движения атомов или кластеров должна определять скорость самого процесса расслоения, если он связан с диффузионными или конвекционными явлениями в системе. Эксперименты показали, что с высокой степенью вероятности температура не влияет на динамику переходных кривых, что указывает на особый механизм этого эффекта, не связанный напрямую с общепринятыми молекулярно-кинетическими закономерностями.

Perception of the Night Scene, An Analytical Study of the Visual Axis Characteristics in the old city canter of Sulaimani
Authors: Faraj Dr. Raz 
Published: March 2019

The perception of individuals to the urban scenes at night is different from that of the day. The previous studies dealt with the subject of the night scene in terms of the effect of artificial lighting in the formation of the night scene and its ability to increase the quality and aesthetics of the scene that designed for night use, but this research deals with other factors. The research problem show itself as: There is a difference in the perception of the viewer at night during the day, where some scenes attract people at night while not attracted by the day and vice versa, while other scenes attract individuals day and night. regardless of the type and efficiency of the lighting used. And the aim of the research, is to study the impact of those characteristics at night where as the people perception differs in the night. The research assumed: the perception of night scene changes according to that visual axes, and the most influential factor in this change is the attraction that result from the presence of a land mark in the axis of motion that changes the characteristics of the visual axis between night and day. And between nightscape and another. The importance of research: is to determine the characteristics that make the scene acceptable to individuals through day and night, and limit some recommendations to hire those characteristics in order to increase the vitality of the urban environment and increase the efficiency of use. In order to achieve this, the research based on a methodology consist of a theoretical base include the explanation of concepts like (urban scene, night scene, visual perception, visual axis) in order to achieve this the research adapt the semantic measurement to measure the people perception of the scene, during the night and day periods of the same scenes, and then compare the results to analyze the differences between them and explore the reasons behind it.
Research has found that the characteristics of the axis differ in terms of their impact on the people attraction, as the emergence of the landmarks at the end of the visual axis is the most influential attraction element to people at night. In the night scene people need to see the land marks in compared to the other elements to be able to complete their journey. And that people do not care about the start points as the end points in the journey, in the night compared to the daytime. Keywords: night scene, visual axis, urban landmarks.
The Effect of Artistic Taste on the Change of Contemporary Kurdish Interior’s Space Elements Case study: Living Spaces in Sulaymania Modern Houses
Authors: Ali Assist. Prof. Dr. Amjad , Abdullah Tablo 
Published: March 2019

The factors of personality and socio-cultural upbringing of the Kurdish individual generated an interior environment with unique attributes. This unique interior environment brought about a collective perspective that is reflected in the Kurdish house environment. Yet, the interior environment of the Kurdish home has changed in response to changes in means of living and a variety of factors affecting it, in the cultural, social, and technological context of the Kurdish society. The traditional elements of the Kurdish house’s interior space are disappearing precipitately. New elements, relations, and styles are filling their places in the design of the interior space that are strange to the traditional ways .
This study raises questions about the rapid and far reaching changes that the components of the interior environment of the Kurdish house have witnessed, and links them to the aesthetic tastes of the Kurdish personality, as the factor that is most expressive of the Kurdish mentality and psychology, which is the artistic taste of the Kurdish personality, and also asking about the impact of artistic taste of the Kurdish personality in that change. The research aims to link the vocabulary of taste and the Kurdish personality to the internal spaces of the Kurdish houses, and then to know the extent of the influence of the artistic taste factors in the change in the internal elements of the Kurdish houses, assuming the difference of the influence of artistic taste in the change in the elements of the internal spaces of the Kurdish houses, influenced by Kurdish personality factors. The research concluded that aesthetic and artistic tastes have a different effect on the selection of interior design elements. Specific factors affect the selection of a particular design regardless of aesthetic values, while other factors are influenced by the values and aesthetic criteria in the selection of interior design elements in the Kurdish house.

This paper presents the study of mechanical properties of short pineapple leaf fibre reinforced polypropylene composites. Pineapple leaf fibre (PALF) is one of them that have also good potential as reinforcement in thermoplastic composite. It is the objective of the current research to characterize the mechanical properties of treated and untreated composites of PALF reinforced polypropylene (PP) composite with four different volume fractions of pineapple leaf fiber (PALF) was fabricated, (5 vol%, 10 vol%, 15 vol% and 20 vol%). The study of this PALF-PP composite demonstrates that bulk density of the composite decrease as the volume fraction increased. From the study about impact strength toward the fibre loadings, impact strength and energy absorbed increase as the volume fraction of fibre increased. Untreated PALF gives greater impact strength than treated PALF. From the experiment conducted on impact test and scanning electron microscopy experiment, untreated fibre produce greater impact and absorbed energy than treated fibre. Until 20% of PALF, result showed strength of the composite still rising to prove that 20% of fibre will fabricate finest fibre loading for the PALF-PP composite was observed from the scanning electron microscope (SEM) micrograph as an evidences on compatibility mechanical properties at the intersectional region of composite.

Published: March 2019

The synthetic organic-inorganic composite membranes have enormous applications in the field of filtration and purification processes. The newly synthesized PVC (polyvinyl chloride) incorporated ZP (zinc phosphate) composite membrane is used as a barrier for the transportation of some strong electrolyte solutions like KCl, NaCl and LiCl. The composite material which used to make the membrane was qualitatively synthesized by sol-gel method of material synthesis. To characterize the structural and thermal properties of membrane there are different techniques like FTIR, XRD, TGA/DTA, SEM-EDX, LCR have been used. By characterizations it is clear that the material has crystalline nature, thermally stable and no breakages or cracks are found on membrane the surface. The electrochemical observation was done by potentiometer, which shows that the membrane is cation selective. To determine the charge density of membrane Teorell-Meyer-Sievers method is used. The observed potential and charge density of the incubated membrane follows KCl<NaCl<LiCl and KCl>NaCl>LiCl order respectively. The other important parameters like transport number, mobility ratio, charge effectiveness are also calculated by observed potential values.

Authors: Saxena Rajiv K. , Balan Anju 
Published: March 2019

Background: The Robson’s Ten-Group Classification System allows critical analysis of caesarean deliveries according to characteristics of pregnancy. The objective was to analyze caesarean section rates in a rural tertiary care teaching hospital in Bangalore, using Robson’s ten groups classification.Methods: This study was done in MVJ Medical College and Research Hospital, a rural tertiary care teaching hospital. All patients who underwent caesarean delivery, between November 2017 and October 2018, were included in the study. Women were classified in 10 groups according to Robson’s classification. For each group, authors calculated its relative contribution to the overall caesarean rate.Results: The overall caesarean section rate was 46.7%. The main contributors to this high caesarean rate were primiparous women in spontaneous labour (group 1) and women with previous caesarean section (group 5). 52.1% of CS were conducted on women who were unbooked or booked at a peripheral health facility and referred to present institution due to complications in labor. Strategies to lower CS rates would include encouraging women with previous CS, to undergo trial of labor to reduce CS rates for group 5C. Sensitization of staff in peripheral medical facilities for early referral of high-risk pregnancies to a tertiary care center for better control of medical complications like hypertensive disorders of diabetes mellitus. Other strategies include offering external cephalic version to eligible women with breech presentation and consider offering vaginal breech delivery to suitable women in groups 6 and 7.Conclusions: The Robson’s classification is easy to use. It is time to implement obstetric audit to lower the overall CS rates.

Authors: Pradhan Shweta , Dave Anupama 
Published: March 2019

Background: Although menopause is a universal phenomenon, there is a considerable variation among women regarding the manifestation of menopausal signs and symptoms. Symptoms experienced with the menopausal transition and early post menopause are varied and span both physical and psychological domains. Therefore, a need is felt to evaluate menopausal symptoms on a pretested scale to provide a subjective and clinically reproducible picture of menopausal symptoms.Methods: A descriptive cross-sectional study was conducted in MYH ,Indore Obstetrics and Gynecology Department, from July 2016 to December 2016.A pretested, semi structured, interview based, oral questionnaire was used to assess the menopausal symptoms and their severity in women of age group 35 to 65 years attending MYH, Indore OPD, using MRS scale and to evaluate these symptoms in perimenopausal as compared to postmenopausal women.Results: The results were evaluated for psychological (P), somatic (S), and urogenital (U) symptoms. A significantly higher percentage of perimenopausal women showed a P score of ≥7; while a higher percentage of postmenopausal showed S score and U score ≥7 ;p ≤ (0.001).Working women seem to suffer more from psychological symptoms whereas nonworking women showed a greater incidence of somatic symptoms.Conclusions: The present study revealed that proportion of menopausal symptoms was significantly high and there was variation of severity of menopausal symptoms with any of the socio demographic variables, menopausal status or duration of menopause.

Published: March 2019

Background: The study was conducted to screen women who have abnormal vaginal discharge with Pap smear to do histopathological analysis of colposcopically directed biopsies.Methods: A prospective analytical study carried out in the department of obstetrics and gynaecology. The patients were randomly selected who fulfilled the selection criteria and was carried out to study the correlation of Pap smear and colposcopy in women with unhealthy cervix. Results: Among all patients 13% were between 20-29 years, 38% were between 30- 39%, 31% belonging to 40-49 years group and 18% was between 50-59%. Among 100 Women studied, 33% were illiterates, 55% had primary/high school education and 12% had Higher education Majority of the patients (68.7%) of CIN occurred in the age group of 30-49years, 41.7% with CIN were paragrvida 2, 43.8% with CIN were paragravida 3 and 18.6% were greater than paragravida 4 showing high incidence of CIN in multiparity.The incidence of CIN was found to be high among the lower income group 87.5%.The major presenting complains in the study patients were white discharge per vagina.Conclusions: Colposcopy was found to be useful in understanding the morphology of the cervical lesion, both of the neoplastic and nonneoplastic ones and was very helpful in planning their management. Cytology is an accepted method for screening for cervical cancer and the value of colposcopy has been recognized. Hence it may be better to utilize cervical cytology smear with colposcopy should be offered as a diagnostic method in all patients with unhealthy cervix.

Published: March 2019

Background: Hypertensive disorder of pregnancy occurs in approximately 6-8% of all pregnancies. The most serious consequences for the mother and the baby are the result of preeclampsia and eclampsia. Lactate Dehydrogenase (LDH) is an intracellular enzyme. Recently LDH has been suggested as potential marker to predict severity of pre-eclampsia. The objective of the present study was to compare the serum lactate dehydrogenase levels in women with preeclampsia and normal pregnant women and to correlate lactate dehydrogenase levels with maternal and perinatal outcome in preeclampsia.Methods: An observational prospective study was conducted on 200 antenatal women attending the labour room emergency. Women with singleton pregnancy and cephalic presentation, from 28 weeks onwards were enrolled in the study. Out of 200, 100 were normal pregnant women and 100 were preeclamptic women. Serum LDH levels were measured in all women and maternal and perinatal outcome was assessed in terms of LDH levels.Results: Higher levels of LDH was observed in pregnant women with preeclampsia (627.38±230.04 IU/l) as compared to normal pregnant women (224.43±116.61 IU/l). The maternal complications were found to be maximum in women with LDH > 800 IU/l. Abruption was the most common complication. The perinatal mortality and neonatal deaths were found to have significant correlation with high LDH levels.Conclusions: Maternal and perinatal complications were associated with higher LDH levels in preeclampsia patients. Serum LDH levels can be offered to all patients of preeclampsia and can be used to predict the prognosis of preeclampsia.
