Bitki paraziti nematodlar (BPN) özellikle de kök-ur
nematodları (Meloidogyne spp.) (KUN),
yaygın olarak dağılım gösteren ve geniş bir ürün yelpazesinde önemli verim
kayıplarına neden olan nematodlardır. Önemli KUN türleri ise, Meloidogyne arenaria Chitwood (1949), Meloidogyne exigua Goeldi, 1892, Meloidogyne graminicola Golden and Birchfield, 1965, Meloidogyne hapla Chitwood,
1949, Meloidogyne incognita (Kofoid and White,
1919), Meloidogyne javanica (Treub) Chitwood, 1949 ve Meloidogyne mayaguensis’dir
(Kofoid and White, 1919). BPN’lerin farklı konukçular ve lokasyonlardaki
dağılımı Türkiye’de incelenmiştir. Çalışmalar sonucunda Tylenchida (Nematoda)
takımına bağlı 56 cinse ait toplam 240 BPN türü Türkiye’de tespit edilmiştir.
Bu nematod türleri, ülkenin 48 farklı bölgesinden 66 bitki ile ilişkili olarak
bulunmuştur. Ülkemizde KUN türleri olarak, M.
incognita, M. arenaria, M. javanica ve M. hapla en yaygın
bulunan türlerdir. M. incognita ve M. javanica türleri ise ekonomik anlamda
tarım ve örtü altı üretimde ciddi sorunlara neden olan türlerin başında yer
almaktadırlar. Nematisitler KUN’lerin uzun süreli baskılanmasını sağlamazlar,
çevresel ve insan sağlığı kaygıları kullanımları üzerinde artan kısıtlamalar
ile sonuçlanacaktır. Tokat (Türkiye) ilinden alınan örneklerdeki KUN türlerinin
teşhisleri morfolojik ve morfometrik özellikler üzerinden klasik yöntemler
kullanılarak yapılmıştır. Teşhis çalışmaları sonucunda elde edilen KUN (Meloidogyne) türlerinin [M. incognita (M.i) ve M. javanica (M.j)] kültürlerinin oluşturulması,
yenilenmesi ve üretimi için serada saksılarda hassas domates fideleri [SC-2121
domates çeşidi (Solanum lycopersicum L.)] üretilmiştir. Çalışmada, yumurta paketi
sayısı ve skala değeri açısından uygulama yapılan domates genotiplerinin hassas
ve dayanıklı olma durumları incelenmiştir. Buna göre; M.i ve M.j
uygulamalarında en yüksek yumurta paketi sayısına sahip Domates-79 ve
Domates-90 genotipleri denemelerde kullanılan tüm kök-ur nematodlarına (M.i ve Mj) karşı 1 ve 2 skala değeri ile dayanıklı grupta yer almışlardır
(9.2±2.74; 8.2±1.58; 2.8±1.24 ve 9.4±2.46). Diğer tüm uygulamalar yumurta
paketi sayısı 11’in üstünde olduğu için 3, 4 ve 5 skala değeri ile hassas
gruplarda yer almıştır.

An Insilco study was carried out on the thermochemistry, mechanism and kinetics of the Hydrogen abstraction reaction of 1,1-difluoro-2-methoxypropane (CH3CH(OCH3)CHF2) with the Bromine monoxide radical (BrO) using the Density Functional Theory (DFT) based M06-2X/6-311++G** method. The energy values were immediately improved via optimization at DFT/M06-2X/6-311++G(2df,2p) level (single-point calculations) of the reacting species involved. The Monte Carlo search on the investigating hydrofluoroether (HFE) showed nine conformers with the lowest global minimum conformer being predicted and considered for this work. The results of this study showed that the atmospheric oxidation reaction of CH3CH(OCH3)CHF2 with the BrO radical proceeded in four (4) plausible reaction routes. The total experimental rate of 4.34*10-06 cm-3 molecule-1 sec-1 for HFE + BrO reaction was estimated with atmospheric lifetime (ALT)/global warming potential (GWP) of 1.80 years and 165.30 respectively. The 3D potential energy surfaces (PES) for the reaction was however constructed at absolute temperature of 298.15 K.

Published: March 2019

Aim: To evaluate an impact of a clinical decision support system (CDSS) in the clinical practice of a hospital on the quality and costs of treatment of patients with severe sepsis and septic shock.Materials and methods: We performed a retrospective analysis of the database in the medical information system qMS (SP.ARM, Russia, St. Petersburg) from 2015 to 2017 on 37,997 patients. In the first study period from January 2015 to June 2016, we analyzed the results of the conventional treatment regimen. From May to June 2016, the CDSS module was implemented into the qMS and the personnel was trained correspondingly. The data collected during the second study period mirrored the results of sepsis treatment with the use of CDSS. We assessed the average number of in-hospital days, duration of stay in the intensive care unit, number of septic shock cases, mortality, and treatment costs.Results: The diagnosis of sepsis was confirmed in 67 patients: in 1.4‰ (27/18,792) before the CDSS was implemented versus 2.1‰ (40/19,205) after the CDSS implementation (p < 0.01). It was found that the use of CDSS integrated into the hospital medical information system reduced the number of cases of septic shock development (p < 0.05). Lethality decreased by 10%. The sepsis-associated mortality showed a non-significant trend to decrease by 10% (p < 0.1). The implementation of the CDSS incorporated into the qMS helped to reduce the number of septic shock cases from 26% (7/27) to 7.5% (3/40) (p < 0.05). There was also a trend towards reduced duration of stay in intensive care unit, as well as towards decreased costs of sepsis treatment by 13% and efferent (extra-corporeal) treatments by 29%; however, the differences were not significant.Conclusion: The CDSS implementation for electronic monitoring of the patient's condition and changes in his/hers parameters allowed for an earlier diagnosis of sepsis. We identified some prerequisites for more rational utilization of medical resources, mainly due to early, targeted treatment of patients with severe sepsis and septic shock; however, additional studies are necessary.

Resumen: El objeto del presente estudio es analizar la situación de desprotección y los problemas con los que se encuentran los Menores Extranjeros No Acompañados (MENA) a partir del día que cum­plen dieciocho años de edad, momento a partir del cual pasan a formar parte de un nuevo colectivo, el de los llamados ex MENA. También se examinan las soluciones actuales existentes en España y en la Comunidad Autónoma de Catalunya para ayudar y acompañar a los miembros de este colectivo en la fase de transición a la vida adulta, así como la regularización de su situación en el territorio español y la eventual adquisición de la nacionalidad española. Para la culminación de ambos procesos, estos jóvenes tienen que demostrar su integración en la sociedad española, requisito que, en la mayoría de los casos, es de difícil cumplimiento a la luz de la falta de formación, del bajo nivel de conocimiento de la lengua española y, en definitiva, de las circunstancias personales en las que se encuentran.Palabras clave: Menor Extranjero No Acompañado (MENA), interés superior del menor, mayoría de edad, desamparo, regímenes de acogida, autorización de residencia, autorización de trabajo, na­cionalidad española.Abstract: The purpose of this paper is to analyze the situation of vulnerability and the problems that the Unaccompanied Foreign Minors, who are nationals of third countries, encounter from the mo­ment they turn eighteen.

Aggregation Similarity Measure Based on Hesitant Fuzzy Closeness Degree and Its Application to Clustering Analysis
Authors: Wang Feng 
Published: March 2019

AbstractIn order to distinguish with effect different hesitant fuzzy elements (HFEs), we introduce the asymmetrical relative entropy between HFEs as a distance measure for higher discernment. Next, the formula of attribute weights is derived via an optimal model according to TOPSIS from the relative closeness degree constructed by the discerning relative entropy. Then, we propose the concept of co-correlation degree from the viewpoint of probability theory and develop another new formula of hesitant fuzzy correlation coefficient, and prove their similar properties to the traditional correlation coefficient. To make full use of the existing similarity measures including the ones presented by us, we consider aggregation of similarity measures for hesitant fuzzy sets and derive the synthetical similarity formula. Finally, the derived formula is used for netting clustering analysis under hesitant fuzzy information and the effectiveness and superiority are verified through a comparison analysis of clustering results obtained by other clustering algorithms.
Quantification of Sand Production Using a Pressure-Gradient-Based Sand-Failure Criterion

Published: March 2019

Summary
Cold heavy-oil production with sand (CHOPS) has been one of the major recovery processes for developing unconsolidated heavy-oil reservoirs by taking advantage of sand production and foamy-oil flow. However, effective characterization and accurate prediction of sand production is still a challenge. In this work, a pressure-gradient-based sand-failure criterion is proposed for quantifying sand production and characterizing wormhole propagation. The proposed sand-failure criterion was initially developed at the pore-scale level, while a pseudointeraction force between two neighboring sand grains was proposed to implicitly represent the potential contributions of cementation and geomechanical stresses to the fluidization of sand. The criterion was then extended to a grid scale within a wormhole because the pressure gradient is constant at either a pore scale or a grid scale. With the bottomhole pressure being an input constraint, the proposed sand-failure criterion was validated with good agreement by reproducing production profiles and wormhole propagation from laboratory experiments and a CHOPS well in the Cold Lake Oil Sands Area. This was a confirmation that the proposed sand-failure criterion can be used to characterize the sand production in a CHOPS process.
Successful Campaign to Install Multi-Sectional Large Diameter Chrome CT Velocity Strings in High CO2 Wells in Bolivia

Abstract
Well intervention projects performed in remote and difficult-to-access areas using coiled tubing (CT) equipment and strings with long lengths and large diameters sometimes represent high investment projects. The use of heavy CT strings can lead to complications during lifting and transport operations. One alternative to address these issues is to transport short sections of CT to the wellsite, then connect two or more CT strings onsite. This paper provides an alternative for offshore operations where crane load capabilities are limited and for land operations in remote locations where heavy loads can compromise transportation.
Conventional methods of joining CT strings are available, such as orbital welding and the use of mechanical connectors (Ehtesham 2008). These methods can be applied under controlled conditions or when the CT strings are of small diameters or lengths that enable them to fit on a single spool and the resulting weight can be accommodated. However, these methods present some shortfalls. Orbital welding requires access to qualified technicians and additional verification of the weld on site, adding time and cost to operations. Welding may also be prohibited based on wellsite conditions. Additionally, welds create de-rated sections on the tubing, reducing the potential run life of the string. Spoolable connectors are a viable option where the two strings may be joined off critical path and when the work reel is capable of holding the combined strings. Some operations must be performed using smaller work reels to accommodate the work area, or involve strings being joined during the operation, which are not ideal situations for spoolable unions. The option presented in this paper provides a new method for joining strings on the fly.
The study was performed to explore the technical feasibility of mechanically joining two CT strings for velocity string (VS) projects. Challenges include making the union of these strings above the wellhead under live well conditions and the load capacity limit of the reels. The study includes design of mechanical joining tools, design of the CT strings, selection of CT hanger tools, and surface equipment. These points also include testing, mechanical stress simulations of the CT, and the procedure used to join the strings.
This paper shows the best operational practices, lessons learned, and field considerations when joining multiple CT string sections of the same or different diameters and wall thickness. Performing those jobs with CT equipment provides a low-cost alternative solution to the use of workover equipment and threaded pipe. This study demonstrates the collaboration performed with an operator to develop a campaign solution for five velocity string jobs in Bolivia.

Abstract
An automated wireline milling solution targeted for removal of wellbore obstructions of a varying type, from scale to metal, with built-in capabilities of autonomous cruise navigation between consecutive obstacles, is presented. This paper highlights design features that made a step change in the efficiency and usability of milling services.
Control challenges are still common in downhole milling technology. Changes in milling target composition, cuttings accumulation around the target, drag forces from production flow, and other variations can reduce system efficiency and result in lost time or failed interventions. In the case of wireline milling technology, inclusion of intelligent on-board electronics in the downhole equipment presents an opportunity to actively control the milling process to optimize rate of penetration and implement additional protections to reduce operational risk. We describe a robotic toolstring that automatically and independently controls a wireline tractor using real-time feedback from a milling cartridge and other on-board sensors. Embedded control algorithms implement intuitive workflows derived from the combined experience of multiple experts in well intervention.
With this automated wireline milling system, the user can initiate the milling process by defining certain milling parameters and then can monitor progress in real time while the downhole robotic tool regulates weight on bit and the milling motor. This new automated downhole control system significantly improves torque-on-bit and weight-on-bit controls yielding superior performance, such as rate of penetration and usability. Dynamic load conditions are handled in a high-speed distributed control loop downhole to get most of bit torque capacity across the entire speed range defined by the motor power curve. Tractor push force is adjusted quasi-instantaneously with changes in cutting conditions. Control responsiveness along with software solutions for tracking of motor stall preconditions and a torque limiter greatly reduce the occurrence of motor stalls arising due to the bit wedging in highly reactive targets. With stall avoidance and an automatic backing-off feature to reengage the bit in case of a sporadic torque spike, direct involvement of an operator is significantly minimized compared to the previous tool generation. Head-voltage stabilization is another factor positively impacting the overall power stability and performance of electromechanical tools downhole. Safety features are also in place to prevent cable twisting and protect assets from overcurrent and overtemperature conditions.
The progressive design of the automated milling tool boosts operational efficiency and autonomy, minimizes human mistakes, and reduces risk of getting stuck during the service. Case histories demonstrate the first field jobs and system integration tests performed with this new tool.
Vertical Seismic Profiling via Coiled Tubing-Conveyed Distributed Acoustic Sensing

Published: March 2019

Abstract
Distributed acoustic sensing (DAS) is a rapidly evolving fiber optic technology for monitoring cement curing, perforation performance, stimulation efficiency, and production flow and, more recently, for performing vertical seismic profiling (VSP). VSP data can be acquired and processed to determine velocity models that are used in surface seismic imaging for reservoir characterization, or for microseismic monitoring of hydraulic fracturing operations. The limitation of conventional VSP data acquisition has been well accessibility, with wireline-conveyed tools deployed during openhole or casedhole logging campaigns before well completion or during workovers. Fiber optic cable conveyance by coiled tubing (CT) expands the opportunity for VSP data acquisition during planned CT interventions. This paper presents an example of a CT DAS VSP acquisition. The processing steps are shown to overcome some of the noise challenges inherent in CT DAS data, such as persistently strong borehole tube waves induced from the surface operations activities. A case study is shown for the depth tie between surface seismic data and the CT DAS VSP derived corridor stack image, demonstrating the viability of CT deployed fiber to acquire DAS VSP data.
Improving Operational Confidence: An Advanced Localized Coating for Coiled Tubing Bias Welds

Published: March 2019

Abstract
Pitting corrosion on the tubing ID has caused failures of CT strings in operations across every operating region, with unconventional plays in North America being especially affected. A localized coating that can be applied to the bias weldment has been developed to protect the most susceptible portion of the coiled tubing string from corrosion. This paper will discuss the development process for the coating as well as initial case histories.
Steel is plastically deformed in the manufacturing process to make coiled tubing, and the product is repeatedly plastically deformed in operations. As a result, coatings have historically not been successful with coiled tubing due to insufficient adherence to the tubing, which is the substrate.
Once the decision was made to pursue a localized coating, a test plan was developed to test different iterations of the coating including coating materials and application processes. The initial testing plan included checking for adherence to the substrate as well as resistance to acid with the goal of highlighting a methodology for a working prototype.
The results of the testing plan are provided and were used to determine the path forward to commission a working prototype. Physical Vapor Deposition (PVD) was selected as the best method for application of the local coating. PVD operates by exciting a target within a vacuum chamber, which coats the substrate. Coiled tubing is a continuous product, which prevents the use of a traditional vacuum chamber. This development led to the creation of the first-ever vacuum chamber of its kind—one that does not entirely enclose the product.
The working PVD prototype has been successfully installed at the manufacturing facility in Houston, and test strings coated locally on the bias welds have been created. The paper will describe the first beta-test strings that have been released to the field and any reported observations from the CT service companies.
This paper describes a new processing technique for the manufacturing of coiled tubing. Initial results show that the coating can dramatically improve operations, especially the prevention of unexpected failures with minimal cost impact to the coiled tubing operator.
