Published: October 2018

Günümüzde imalat sektöründe bulunan şirketlerin,
üretim performansını, miktarını ve diğer değişkenleri tahmin edebilmesi
rekabet ortamında rakiplerine ciddi bir avantaj sağlamalarına sebep olmaktadır.
Üretim miktarlarının tahmin edilmesi tesisin gelecekteki giderlerini, üretim
tezgâhlarındaki hata oranlarını ve karşılaşılacak krizlerin önceden tespit
edilmesini sağlayarak verimlilik (etkililik) artışı sağlanmasına olanak
tanımaktadır. Bu kapsamda talaşlı imalat sektöründe üretim performansının zaman
serisi analizi kullanılarak yüksek doğrulukla ve hızlı bir şekilde tahmin
edilmesi amaçlanmaktadır. Bunun için AR ve ARIMA metotları karşılaştırılarak
uygun model seçimi gerçekleştirilmiştir. Seçilen model kullanılarak gerçeğe
yakın tahmin değerlerine ulaşılmıştır. Modellenmiş üretim performansı değerinin
üretim miktarı, üretim tonajı, üretilen parça başı ağırlık, kalıp revizyon
süresi ve bakım arıza süresi değerlerinin her biri ile polinom regresyon
yöntemi ile analizi yapılıp model oluşturulmuş ve performans tahmin değerinden
yola çıkarak bu değerlerin her birisi için ileriye dönük tahmin edilmiştir.
Elde edilen tahmini performans değerinden belirli ortalama hata payları ile
tezgâhlarda üretilen adet sayısı (%16), tonaj miktarı (%9), bakım-arıza süresi,
kalıp revizyon süresi (%51), adet başı tonaj oranı (%18) gibi diğer verilerle ile ilgili tahminlerin yapılması sağlanmıştır.

Published: October 2018

The interaction genotype versus environment makes it difficult the genetic improvement of the species for the selection of more adapted and stable genotypes. Thus, the objective of this work was to evaluate new clones of early dwarf cashews, in terms of stability and adaptability, employing the GGE biplot methodology.
The experimental design was based on randomized blocks with four replications and 15 treatments (different
clones). The variables evaluated were cashew production per plant (PCP), average mass of chashew (MMC)
and early harvest (PRE). The clones G1 and G3 for MMC, G15, G2, G14 and G8 for PRE and G3, G10 and G2
for PCP approached the ideotype; the clones identified as top for each characteristic were not coincident; the
majority of the clones were stable for MMC, while for PRE and PCP were not stable; the clone G4 had the best
average in PRE, but with low stability; in the GGE biplot the environments A3 for MMC, A4 to PRE and A5 for
PCP were the most discriminating; all environments had greater contribution in the differentiation of clones in
PRE and MMC, for PCP were the environments A4 and A5; in relation at the average representativeness the
environments A1 in MMC and A2 for PRE and PCP stood out.

Published: October 2018

Ataerkil toplumlarda kadınlar kamusal ve özel alandaki eşitsizlikler
sonucunda ayrımcılığa maruz kalmaktadırlar. Söz konusu eşitsizlikler kamusal
alanın önemli bir bölümünü teşkil eden iş hayatında da geçerlidir. Kadının
eğitim alması, meslek edinmesi ve hatta çalıştığı alanında yönetici konumuna
gelmesi bile bu eşitsizliklerin ortadan kalkmasını mümkün kılmamaktadır. Bu
makalenin amacı kadınların iş alanında karşılaştıkları zorlukları ve bunlarla
başa çıkma stratejilerini belirleyerek ayrımcılık ve eşitsizlikleri hangi yollarla
aşmaya çalıştıklarını incelemektir. Çalışmada yönetici pozisyonunda çalışan
kadınların çalışma hayatlarındaki deneyimleri, karşılaştıkları sorunlar,
bunlarla başa çıkma stratejileri incelenmiş ve eşitsizliklerin aşılmasında
sahip oldukları sosyal çevrenin rolü sorgulanmıştır. Çalışmanın örneklemini
Türkiye’de bir teknoparkta çalışan kadın yöneticiler oluşturmaktadır. Alan
araştırmasında kadın yöneticilerle derinlemesine mülakatlar yapılmıştır. Çalışmanın
savı kadınların eğitim düzeylerinin yükseldiği ve profesyonel alanda yönetici
konumunda bulunmalarına rağmen kamusal ve özel alanda iş hayatında ataerkil
davranış kalıplarını sürdürüp içselleştirmekte ve hatta yeniden üretebildikleridir.
Sosyal çevre ve sosyal sermaye, eşitsizliklerin giderilmesinde önemli bir etken
olmakla birlikte çalışma hayatındaki eşitsizlik ve ayrımcılık örüntülerinin
ortadan kaldırılmasında sadece kolaylaştırıcı etki göstermekte, bunların
ortadan kaldırılmasında yapısal bir katkı sağlayamamaktadır.

Modified Rectorite Provides Reliable Rheology and Suspendability in Biodiesel-Based Fluids

The use of organophilic clays as additives to provide proper rheological and filtration properties in nonaqueous drilling fluids (NADFs) has long been a topic of study. Currently, most of these clays are based on the modification of bentonite with quaternary ammonium salts. As new NADF systems emerge, novel clay-modification technologies are needed to obtain more-effective organophilic clays for specific drilling fluids. This paper introduced a modified rectorite designed for biodiesel-based drilling fluid (BBDF).
Introduction
Biodiesel has drawn a great deal of attention from petroleum scientists and drilling engineers who are seeking environmentally friendly, high-performance, low-cost drilling fluids. The advantageous properties of biodiesel—such as a high flash point (for fire safety), sufficient viscosity (to carry cuttings to the surface during drilling), low eco-toxicity, excellent biodegradability, and good lubricity—make it suitable as a base oil for drilling fluid. Biodiesel also is relatively inexpensive in many situations. Many investigations and trials are being con-ducted on BBDF, suggesting some exciting results.
A general necessity for new drilling-fluid techniques is to customize a series of corresponding chemical additives; BBDF is no exception. Preliminary experience has shown that an additive used in traditional oil-based drilling fluids (OBDFs) may be unable to perform well in a BBDF system. Consequently, new additives should be developed for BBDF in order to obtain the optimal operational and environmental properties.
Traditionally, most organophilic clays for drilling fluids are based on the intercalating reaction between bentonite and quaternary ammonium salts, which are classified as cationic surfactants. However, this type of organobentonite (OB) still has some disadvantages, such as eco- toxicity and high resistance to degradation when discarded in the environment.
Inexpensive rectorite has been selected to replace the commonly used bentonite as the raw clay to produce organophilic clay through a modification reaction with nonionic surfactants. Crucial properties, including swelling index, viscosity, yield point, gel strength, and suspendability, were evaluated.
Water-Injection Techniques Increase Recovery in Conventional Gas Reservoirs

Published: October 2018

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 191206, “Exploiting Water-Injection Techniques for Increasing Gas Recovery in Conventional Gas Reservoirs,” by Keval Darvesh Rambaran, SPE, Sarah Tammie Chin Chee Fat, SPE, and Lugard Evans Layne, SPE, University of Trinidad and Tobago, prepared for the 2018 SPE Trinidad and Tobago Section Energy Resources Conference, Port of Spain, Trinidad and Tobago, 25–26 June The paper has not been peer reviewed.
Primary gas recovery for a volumetric reservoir ends when the reservoir pressure declines below the value required to flow gas to the surface at the sales-line pressure. Secondary gas-recovery techniques can then be used to increase the recovery. The most common of these techniques is gas compression, but another feasible technique that is rarely explored is water injection. This paper evaluates the incremental benefit of water injection in a conventional gas reservoir when compared with gas compression.
Introduction
An operator hopes to increase the recovery in Reservoir TM-20 in the Sorrel Field offshore Trinidad and Tobago by use of water injection once the technique is deemed more economical than gas compression. The wells in the reservoir are drilled from the Tamarind Platform, which also acts as a hub for the separation of fluids from fields in the immediate vicinity. Gases and liquids are piped through separate lines, with the liquids heading to the onshore liquid-processing facility. However, the company can modify the platform separators to operate in three phases and use the produced water for injection. Company records show that the average water-production rate from the platform is approximately 5,000 BWPD. If the shut-in wells were to be opened, roughly 10,000 BWPD of produced water and 15 MMscf/D of gas would be added for each well until liquid loading, thus increasing gas output significantly.
Field History
The Sorrel Field is a retrograde gas-condensate field located in the Columbus Basin, which has been producing from the TM-20 reservoir since 1998. The reservoir is a faulted sandstone formation of good quality that is divided into two hydrocarbon-bearing segments and underlain by an active aquifer. Segments 1 and 2 have been producing from Wells X and Y and Wells A and B, respectively, as shown in Fig. 1.
Unlike Segment 1, primary gas recovery in Segment 2 ended because of a decline in the reservoir pressure, thus making it a suitable choice for water injection. Segment 2 is a wedge-shaped structure bounded by two faults, with both faults being interpreted as sealing. Production in Segment 2 began in April 1999 with a reservoir pressure of 4,732 psig. It ended in January 2014 because of an inability to flow at the sales-line pressure of 950 psig.
RADIATE – Radial Dysplasia Assessment, Treatment and Aetiology: Protocol for the development of a core outcome set using a Delphi survey
Authors: Murphy George , Logan Malcolm , Smith Gill , Sivakumar Bran 
Published: October 2018

Abstract
Background

Radial dysplasia (RD) is a disfiguring, potentially disabling congenital upper limb anomaly. Multiple surgical techniques are in current use, with little agreement on the optimal treatment approach. At present, no core outcome set exists specifically for radial dysplasia, and the literature is dominated by retrospective case series. A recent systematic review by this group demonstrated significant heterogeneity in both which outcomes are measured, and how they are measured.

Methods

The RADIATE study will conduct a three-round online Delphi process, involving adult radial dysplasia patients, the parents of children with radial dysplasia, hand surgeons and hand therapists. The initial list of outcomes is drawn from our recent systematic review and will be supplemented by suggestions from the stakeholder groups. Following the Delphi process, outcomes which meet the ‘consensus in’ definition will be ratified at a final consensus meeting, and a method of outcome measurement agreed for each. Where appropriate, this will overlap with the outcome measures specified in the forthcoming ICHOM congenital upper limb anomalies standard set.

Discussion

The Radial Dysplasia Assessment, Treatment and Aetiology (RADIATE) study aims to address the uncertainty in the treatment of radial dysplasia, and to begin to answer the question “what is the most appropriate treatment for children with radial dysplasia?” by establishing a core outcome set.

The Fortress of the Holy Cross: Foundation and Construction (1722–1735)
Authors: Abdusalamov M.-P. B. , Chekulayev N. D. 
Published: October 2018

The current research is based on archival documents and works by domestic specialists in Caucasian studies. It features the foundation and construction of the Fortress of the Sacred Cross. Its history began during the famous Persian, or Caspian, Campaign of Peter the Great (1722–1723). As a result, the Caspian provinces of Iranand the entire Seaside Dagestan entered the Russian Empire. To protect the new territories, a system of military fortifications was built. The Fortress of the Holy Cross was founded by Peter the Great in September, 1722, inthe estuary of the SulakRiver. It gradually became one of the economic, administrative and political centers of the Caucasus.Owing to its strategic location, the Fortress of the Holy Cross played an important historical role in the Caucasian policy ofRussia: it wasRussia’s pillar of support in the region and shielded the southern boundaries of the Empire. The article focuses on the history of the garrison, which has long remained understudied by domestic historiographers. Some Russian researches devoted to the Caucasian policy in general mention the political and economic role of the Fortress. However, there have been no separate studies devoted to the history of the Fortress – a lacuna the authors of the article attempt to bridge.

Published: October 2018

Abstract
Bacterial community diversity of bulk water and corresponding biofilms of four intensive care units' (ICUs) drinking water systems were studied and compared using 16S rRNA gene amplicons and next generation sequencing. Proteobacteria, mainly Alphaproteobacteria and Betaproteobacteria were dominant in the bulk water and biofilms. Principal component analysis showed different bacterial communities characterizing each of the bulk water and the biofilms in three of the studied ICUs. Taxonomic classification and comparison of different genera between samples highlighted the dominance of Aquabacterium (80%) and Novosphingobium (72%) in bulk water while biofilms harbored different bacteria affiliated to Pelomonas (97%) and Caulobacter (96%), Porphyrobacter (78%) and Staphylococcus (74%). Staphylococcus aureus was the only possible pathogen found with low percentage (2.32%) in three of the ICUs' biofilm and only in one of the ICU's bulk water. This study sheds light on the prevalence of unculturable bacterial flora in the biofilm ignored by the microbiological standard methods. This study was performed on tap and bulk water from ICUs; however, it indicates the need for further studies to investigate the function and activity of the microbial diversity in order to assess the real risk presented by this water microflora on patients' health.
Experimental Studying of the Variations of Surface Roughness and Dimensional Accuracy in Dry Hard Turning Operation
Authors: Yousefi S. , Zohoor M. 
Published: October 2018

Objective:
Hard turning in dry condition using cubic boron nitride tools, as an alternative of traditional grinding operation, is an advanced machining operation in which hardened steel with the hardness greater than 46 HRc is machined without the use of any coolant.

Method:
In the hard turning process, due to its hard nature, usually the cutting depth is selected lower than or equal to the nose radius, and the cutting zone is mainly limited within the tool nose area. Thus, unlike the traditional turning, the effect of the nose radius on the surface finish and dimensional accuracy becomes more complicated. Therefore, in this paper, firstly, the effect of processing parameters such as nose radius on the surface roughness and dimensional accuracy is investigated. Then, the relationship between the surface finish and dimensional accuracy variations with vibration, cutting forces, and tool wear is studied experimentally. The results revealed that feed rate is the most important factor influencing the surface roughness, whereas spindle speed and cutting depth are insignificant factors. On the other hand, cutting depth and spindle speed have the greatest effect on the dimensional accuracy, while nose radius has no significant effect. The vibration and wear analysis revealed that compared with the vibration, the tool wear has no considerable effect on the dimensional accuracy. It was also observed that the spindle speed has a contradictory effect on the surface roughness and dimensional accuracy. The best dimensional accuracy is obtained at 500 rpm, while the best surface quality is achieved at 2000 rpm.

Result:
The obtained results also showed that increasing the feed rate from a particular value not only leads to no significant changes in the surface roughness value but in some cases can also decrease the surface roughness.

Conclusion:
According to the analysis results, the lowest cutting depth, the moderate feed rate, and the speed lower than 1100 rpm provide the best dimensional accuracy. Compared with carbides and ceramics, cubic boron nitride tools produce a better surface roughness at both higher cutting depth and speed. 0.202 µm is the best surface roughness that was obtained at rε = 1.2 mm, N = 2000 rpm, f = 0.08 mm/rev, d = 0.5 mm which is comparable with the surface quality obtained by the conventional grinding operation.
