Abstract
It is a challenge to drill a highly deviated or horizontal hole in high permeable formations. High differential pressures may lead to several problems like tight holes, wellbore instability, differential sticking and mud loss while drilling across these permeable or fractured formations. It was always preferred to drill these wells with Oil base muds which showed some success. While operators always prefer the standard solution, which is casing isolation for problematic sections, challenges have increased due to continuously drilling in depleted reservoirs which leads to considerable nonproductive time.
The other solution to overcome such problematic sections was to re-design a fluid system that would target drilling through serious of highly permeable sand and shale formations. The fluid system would primarily address shale inhibition along with effective bridging, minimizing pore pressure transmission and wellbore strengthen with increased hoop stress in the wellbore. Software modelling and permeability plugging tests were performed to evaluate the fluid behavior under downhole conditions and to predict the characteristics of induced micro fractures based on rock mechanics. Porosity, permeability and induced micro fractures were considered to optimize the bridging mechanism. It was identified that normal bridging solutions involving calcium carbonates and graphite material were not enough to address the pore pressure transmission problem. It was essential to include a micronized sealing deformable polymer along with normal bridging material was effective in plugging pore throats and minimizing fluid invasion. The deformable polymer component is able to re-shape itself to fit a broad range of pore throat sizes which was previously unattainable with conventional bridging technology which was confirmed by particle plugging tests.
A one well was identified to be drilled in highly depleted reservoir at an inclination of almost 45 degrees. The section involving the highly depleted and permeable sand involved drilling highly stressed shale formations which requires high mud weight for their stability. This was the first attempt on a high-angle well with development drilling operations in Kuwait and was performed to facilitate the successful drilling of the reservoir. Drilling and logging were successfully performed along with logging and LWD runs with no recordable differential sticking or losses incidents.
This paper also presents 2 successful applications in the same field with the application of proper bridging and utilization of deformable sealing polymer to address drilling problems through highly depleted and permeable formations while managing over balance of 3500 psi across them.

Authors: El-Nobi Eman Fouad 
Published: November 2018

The spatial distribution of Erythemal Ultraviolet Dose Rate (EUV) at noon in mW/m2 observations gotten from the Ozone Monitoring Instrument (OMI) are presented over Egypt covering the geographical domain (22.5°–31.5°N, 25.5°–35.5°E) during twelve year from 2005 to 2016. With the end goal of mapping contour, with a spatial resolution of 1°×1° the results illustrated by monthly, seasonally and all period contour maps indicate high similarity of EUV in all years. Monthly correlation (R2) relationship between EUV and Latitude also estimated in simple linear form. High R2 was found in December and January (97%) were low one was found in July (53%). In the frame of the variability, Egypt was considered as an average area; the box-whisker plots were created for average monthly and annual values of EUV. The monthly mean of EUV values are lower in the winter months (December to February) 116.17±2.30 mW/m2 compared to those in the summer months (June to August) 282.36±2.87 mW/m2. The annual mean of EUV values are lower in 2015 (204.15±60.41 mW/m2) and higher in 2013 (213.13±60.34 mW/m2).

İki ve üç
boyutlu nesnelerin birbirleriyle ve çevreyle ilişkilerinin anlaşılmasında,
geometriyle ilişkili önemli kavramların başında gelen uzamsal yeteneğin payı
kuşkusuz büyüktür. Uzamsal yeteneği ortak tanımlara bakıldığında uzamsal
yetenek üç boyutlu uzayda cisimleri ve bileşenlerini zihinde hareket
ettirebilme ve canlandırabilme yeteneği olarak tanımlanmıştır. Öğrencilerin
geometrik düşünme düzeylerini geliştirmek, matematik eğitiminin en kritik
amaçlarından biri olmalıdır. Bu araştırmanın amacı ortaokul öğrencilerinin açık
uçlu sorular ve çoktan seçmeli sorular oluşan testlerin uzamsal yetenek
düzeyini belirlemede etkililiğinin karşılaştırılmasıdır. Bu iki test yönteminin
öğrencilerin uzamsal yetenek becerilerini belirlemede nasıl farklılıklar ortaya
çıkardığı belirlenmiştir. Bu amaç doğrultusunda bu araştırma nitel
yaklaşımlardan durum çalışması olarak desenlenmiştir. Araştırmanın amacına
uygun olarak amaçlı örnekleme yöntemi kullanılmıştır. Geometri konusunda
ortaokul seviyesinde en fazla bilgi düzeyine sahip olan 8.sınıf öğrencileri
seçilmiştir. Araştırmanın çalışma grubunu Türkiye’nin kuzeyinde bir devlet
ortaokulunun 8.sınıfında öğrenim gören 77 öğrenci oluşturmuştur. Araştırmada
veri toplama aracı olarak alan yazında kabul gören MGMP isimli uzamsal yetenek
testinden seçilen 10 soru hem açık uçlu olarak hem de çoktan seçmeli olarak
kullanılmıştır. Araştırma bulgularına göre 77 öğrencinin 10 soruya çoktan
seçmeli olarak verdikleri yanıtların %68’i doğru olurken, bu 10 soruya açık
uçlu olarak verdikleri yanıtların sadece %45’i doğru olarak kodlanmıştır. Buna göre öğrencilerin uzamsal yeteneğini
belirlemek için tercih edilen çoktan seçmeli testte öğrencilerin daha başarılı
sonuç gösterdikleri anlaşılabilir. Ancak buna karşın öğrencilerin özellikle
çizim becerisi gerektiren sorularda (soru11, 20, 22 ve 23) öğrencilerin çoktan
seçmeli sorularda daha başarılı oldukları görülmüştür.

Published: November 2018

Abstract
We conducted an 8-week feeding trial to determine the effects of dietary starch levels on growth performance, body composition, and digestive enzyme activities of juvenile soft-shelled turtles. Six fish meal-based diets containing 120, 180, 240, 300, 360 and 420 g kg−1 cornstarch were formulated. Body weight gain (BWG), crude protein concentration in whole body, as well as protease activity increased with increasing dietary starch levels until the highest at 240–300 g kg−1, but it was decreased at higher dietary starch content. In contrast, the feed conversion ratio, moisture content and hepatosomatic index were the lowest at 240–300 g kg−1 of cornstarch. The weight gain correlated significantly with the survival rate, the crude protein composition and the protease activity, but correlated negatively to the moisture content and the hepatosomatic index. The optimal dietary starch levels for the maximum BWG and maximum protease activity were 267.25 g kg−1 and 266.79 g kg−1, respectively. The α-amylase activity was the lowest at 120 g · kg−1 of cornstarch, and increased with increasing cornstrach content. The lipase activity and the amount of crude lipid in the turtles were not influenced by dietary cornstarch. Our results suggest that around 300 g kg−1 of cornstarch in diets is optimal for juvenile soft-shelled turtles.
Air Ionization in Livestock Buildings – A Review
Authors: Herbut Eugeniusz , Sosnówka-Czajka Ewa , Skomorucha Iwona 
Published: November 2018

Abstract
Research has shown that microclimate is determined not only by air microparticles, but also by the degree of air ionization. Ions affect the body through the respiratory tract and skin. Exposure of reared chickens to elevated air temperature (37°C–23°C) was found to accelerate the break-down of negative ions compared to temperature lower by 10°C. Negative air ionization offsets the adverse effect of elevated temperature on chickens. Higher (85%) air humidity during rearing of chickens was also observed to destroy negative ions. Research findings indicate that air ionization is an environmental element that contributes to improving performance in broiler chickens. Many studies have also confirmed a positive effect of air ionization on the body weight and health of piglets.

Abstract
The main sources of radon in the air of dwellings are soil, building materials, and groundwater. This study aimed to determine the exhalation rate of 222Rn from samples made of concrete and cement mortars, as well as to evaluate by means of gamma spectrometry the hazard indexes associated with other radionuclides present in the studied samples of building materials. The results obtained allowed the comparison of the exhalation rate of radon using theoretical calculations based on one-dimensional and three-dimensional models. Measurements of the activity concentration of radon in air was performed by AlphaGuard radon detector. Furthermore, obtained results were compared with the measurements performed inside the concrete test cells. These test cells were built with the aim of simulating a dwelling in small dimensions and to evaluate indoor radon activity associated with concrete. Consequently, the obtained results of radon exhalation rate, in becquerel per meter squared per hour, for the concrete was 2.55 ± 0.03 Bq·h−1·m−2 for the 1D model and 0.461 ±0.008 Bq·h−1·m−2 for the 3D model. The exhalation rate of radon, for the cement mortar was 1.58 ± 0.03 Bq·h−1·m−2 for the 1D model and 0.439 ± 0.011 Bq·h−1·m−2 for the 3D model. The indoor concentration of 222Rn from the test cell was 112 ± 9 Bq/m3. These values were below the limit of 300 Bq/m3 recommended by the International Commission on Radiological Protection (ICRP) and <148 Bq/m3, the limit recommended by the US Environmental Protection Agency (US EPA). Even so, these values should be the subject of concern since that activity is related only to the contribution of concrete walls.

Published: November 2018

Abstract
Zirconium alloys used widely in nuclear industry as fuel claddings are prone to violent oxidation in water steam atmosphere in the case of loss of coolant accident (LOCA). Accompanying generation of large quantities of heat and explosive gaseous hydrogen may lead to destruction of nuclear core. As the safety of nuclear installations is of primary importance, intensive research works are conducted on the development of so-called accident tolerant fuels much less prone to oxidation. In this paper, the application of external zirconium-silicide coatings deposited by magnetron sputtering is proposed. The preliminary results of their synthesis and studies of air oxidation properties at elevated temperatures are presented.

Published: November 2018

Abstract
The process of cross-linking of polyethylene using gamma radiation (γ) and electron beam (EB) was tested from the point of view of density of foam. Particular attention was paid to the postradiation oxidation effect of the polymers. The study used two types of radiation sources of varying dose rates: gamma radiation (4 kGy/h) and EB (14 000 kGy/h). Radiolysis studies of the polymers used the radiation yield of hydrogen evolved (G
H2
, approximately proportional to the number of radicals) and radiation yield of oxygen absorbed by the polymer (G
O2
). Oxidation of polymer due to radiation was also evaluated using diffuse reflectance spectroscopy.

Published: November 2018

Abstract

Introduction. Due to the increasing incidence of a number of different diseases of Polish society , there is also a growing need for professional nursing care to be able to objectively assess how it should be expected to find out what the patients’ expectations are in this situation.

Aim. The study aimed to define the main patient expectations for nursing staff during hospitalization. The purpose of the work was also to get to know the public opinion about the model of a modern nurse.

Material and methods. The study was carried out on 200 patients hospitalized at various hospitals in Krosno, Strzyżów and Jasło at the end of January and February 2017. The method of the diagnostic survey was used with the questionnaire survey, which consisted of 10 closed questions.

Results. For 87% of patients the most important care is caring care, 79.5% of the respondents require good practice. For 66% of respondents it is important to provide information on their questions, while 51.5% of people are important to enable contact with family. The overwhelming majority, (95%) of respondents stress the importance of possible assistance rather than helping them in their everyday life in the ward. 72.5% of patients assess the nurse-patient relationship very well.

Conclusions. For patients a very important element of hospitalization is caring nursing care. Hospitalized people are much more likely to appreciate the professional experience of nursing staff than achieved by them academic titles. The profession of a nurse/nurse is perceived by patients as a separate profession. Patients appreciate the smile and nice attitude of the nursing staff.
Olfactory functions in Behçet’s disease: A review
Authors: Muluk Nuray Bayar 
Published: November 2018

Abstract

OBJECTIVES. We reviewed the relationship between olfactory functions and Behçet’s disease (BD).

MATERIAL AND METHODS. We searched Pubmed, Google, Google Scholar and Proquest Cebtral Database with the key words of “olfactory”, “functions”, “smell”, “nasal” and “Behçet’s disease”.

RESULTS. Behçet’s disease influences the nasal mucosa. Nasal mucosal inclusion causes mucosal ulcers, pain, burning, nasal obstruction, epistaxis, nasal itching and dysosmia. Nasal cartilage deformity is also reported. The higher rate of comorbid chronic rhinosinusitis (CRS) in BD patients may likewise be because of the complex mechanism of the disease inclining the host tissues to bacterial infections. Olfactory functions may decrease in BD. Odor identification may be lower in patients BD.

CONCLUSION. An olfactory dysfunction may be seen in patients with BD. BD patients should be evaluated for the involvement of the olfactory function and may require treatment because of a malfunction of the olfactory system that influences the quality of life. Neurological involvement associated with BD might play a more important role in causing olfactory dysfunction than mucosal involvement.
Comparative analysis of the data obtained in computerized posturography and videonystagmography for patients with peripheral vestibular deficit

Published: November 2018

Abstract

BACKGROUND. Vestibular disorders are a group of widely spread diseases that have as a common denominator the disturbance of the equilibrium system. The assessment of vestibular disorders consists in a complex examination of the patient including a thorough anamnesis, a rigorous clinical examination and multiple functional explorations.

OBJECTIVE. To asses weather there is a correlation between the data obtained in posturography and those obtained in the videonystagmography in patients with peripheral vestibular disorders.

MATERIAL AND METHODS. Collecting data from the observation sheets of patients diagnosed with peripheral vestibular syndrome and examined in the Department of Otorhinolaryngology of the “Sfanta Maria” Hospital in Bucharest over a period of 18 months.

RESULTS. We analyzed a number of 97 cases of patients diagnosed with peripheral vestibular disorder. A large number of patients (49) had correlated changes in the caloric tests and also in the posturography. A second group of patients (43) had changes in caloric tests but with no changes in posturography. The third group of 5, paradoxically, had a vestibular deficiency in posturography associated with normal caloric reactivity.

CONCLUSION. The results obtained with the videonystagmography are correlated with those of the caloric and rotational videonystagmographic tests in the case of acute vestibular diseases. In chronic vestibular diseases, it is possible to find caloric vestibular paresis in the presence of a normal posturography. The “vestibular omission” is a phenomenon in which the patient does not use the vestibular input of a normal labyrinth with caloric and rotary tests within normal limits. As no vestibular examination can be considered as selfstaging diagnosis, we always have to establish the final diagnosis correlating the results of all the tests available.

Published: November 2018

Abstract
Extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells. It is most often located in the head and neck region. Extramedullary Plasmacytomas are more predominant in males who are in the 5th – 6th decade. In this report, this patient, who is a young female, presented to our clinic with history of intermittent nasal obstruction for the past year. She was diagnosed with extramedullary plasmacytoma and was subjected to radiotherapy. The clinical and histopathologic findings of plasmacytoma are discussed. In order to exclude systemic involvement, a systematic approach using clinical, laboratory and radiologic investigations was performed. Extramedullary plasmacytoma of the nasal cavity is rare and should be considered in the differential diagnosis of nasal cavity masses, especially in the young age group.
