Casing while Drilling (CwD) have been through advancement cycles from where this technology started since the early 1970's. At that time, CwD requirements were understood, but the equipment was not available. As application for CwD grows with a variety of challenges, more suitable equipment is now available – not only on the surface but also the downhole to meet the operation objective.

In one of the applications here in Middle East, top hole sections drilling through different formations consists of carbonate, sand and shale. However, carbonate formation in this application is the main challenge with drilling through the losses, followed by formation instability, which resulted in stuck incidents.

CwD strategy divided into two elements – remedial and optimization. For remedial element, offset analysis required to determine the level of formation instability surrounding the subject well where a decision will be made either to use CwD from the begging or to be considered as a contingency in case unforeseen borehole instability issue encountered. Whilst for optimization element, CwD application will be utilized to drill the top sections regardless the borehole instability risk, in this element it is must to show some time savings to cover the additional involved cost.

In one of the wells as an example, offset wells showed a history of formation instability related issues with one of the wells was abandoned, and another one was side-tracked. CwD was selected instead of drilling conventionally, and as a result, this well successfully drilled to casing depth without any of the lost time due to hole problems that was experienced by most of the offset wells.

With a much better understanding of drilling challenges, equipment availability, and capability, CwD will be able to open more opportunities to drill the well safer and faster as becoming a standard operation in drilling top sections. This paper discusses in general the challenges and solutions provided along with field results.

Authors: Pazyuk I.M. , Fominykh T.S. , Medvedeva K.D.
Published: February 2020

В статье рассмотрена возможность выпуска хищных клопов (подизуса, ориуса, незидиокориса и макролофуса) против вредных насекомых-переносчиков вирусных болезней на меристемном картофеле в теплицах. В садковых экспериментах в 2016–2017 годах оценивали вероятность переноса Y-вируса картофеля этими энтомофагами. Опыты показали, что ни один из видов клопов не переносил Y-вирус. Однако было выявлено, что незидиокорис и макролофус повреждали рассаду картофеля в отсутствии животной пищи (вредителей, подкормки). В связи с этим для биологической защиты меристемного картофеля от вредителей можно рекомендовать только клопов подизуса и ориуса.

The predatory bugs Podisus maculiventris, Orius majusculus, Nesidiocoris tenuis and Macrolophus pygmaeus were tested for control of pests in potato meristem culture in greenhouses. The risk of Y potato virus transmission by these entomophagous bugs was estimated in cage experiments in years 2016–2017. It has been shown that none of the bugs tested was capable of transmitting the Y-virus. However, N. tenuis and M. pygmaeus have been shown to damage potato seedlings in the absence of animal food (pests or factitious food). Therefore, we can recommend only P. maculiventris and O. majusculus for pest control in potato meristem culture in greenhouses.

Authors: Calderon-Villarreal Alheli , Mujica Oscar J. , Bojorquez Ietza
Published: February 2020

Objective. To assess the association between intersectional disadvantage and clinically significant depressive symptoms (CSDS), describing the magnitude of social inequalities in the prevalence of symptoms among adult women in Tijuana, Mexico.

Methods. This was a cross-sectional study. CSDS were assessed using the Centers for Epidemiological Studies Depression Scale among a probability sample of 2 345 women from 18 – 65 years of age in 2014. CSDS prevalence was calculated according to categories of three social stratifiers: socioeconomic status (SES), educational attainment, and fertility (number of children). Social inequality was measured with the slope index of inequality (SII) and the concentration index (CIx). Intersectionality among stratifiers was explored descriptively and with multivariable regression analysis.

Results. CSDS prevalence was 17.7% (95%CI: 15.1% – 21.0%). The SII and CIx showed inequity in all social stratifiers. The absolute difference in CSDS prevalence between the lowest and highest ends of the SES gradient was 21.9% (95%CI: 21.5% – 22.4%). Among the most disadvantaged women, i.e., those at the intersection of lowest SES, lowest educational attainment, and highest fertility, the CSDS prevalence was 39.5% (95% CI: 26.0% – 52.9%).

Conclusions. Disadvantage along multiple axes was associated with CSDS. Efforts to improve the mental health of women should include equity-oriented policies that address its social determinants.

Se analiza la consciencia y las experiencias aprehendidas que pasan al inconsciente transformándose en hábitos. Las metáforas estructurales (lingüísticas) son un atajo para comprender el entorno y el intercambio comunicacional. Existen aspectos de la neuroplasticidad relacionados con el cambio de hábitos sociales y la manera en que la estructuración de patrones conductuales constantes se refleja en zonas del cerebro donde se detectan conexiones sinápticas que manifiestan cambio. En los procesos de percepción que configuran la consciencia intervienen patrones sociales que la determinan reforzando la idea de que el aprendizaje de habilidades sociales se fortalece gracias a la repetición de conductas.

The understanding of climate change is curial for the security of hydrologic conditions of river basins and it is very important to study the climate change impacts on streamflow by analyzing the different climate scenarios with the help of the hydrological models. The main purpose of this study is to project the future climate impact on streamflow by using the SWAT model. The multi-model projections indicated that Upper Ayeyarwady River Basin is likely to become hotter in dry season under low rainfall intensity with increasing temperature and likely to become wetter but warmer in both rainy and winter season because of high rainfall intensity with increased temperature in future. The impact of climate change scenarios is predicted to decrease the annual streamflow by about 0.30 to 1.92% under RCP2.6, 5.59 to 7.29% under RCP4.5 and 10.43 to 11.92% under RCP8.5. Based on the change in high and low flow percentage with respect to the baseline period, the difference between high and low flow variation range will increase year by year based on future scenarios. Therefore, it can be concluded that it may occur more low flow in the dry season which leads to increase in water scarcity and drought and more high flow in the wet season which can cause flooding, water insecurity, stress, and other water-related disasters.

Biosynthesis of silver nanoparticles (AgNPs) using mangosteen bark extract, modification and its application in detecting melamine has conducted. This research aimed to synthesize AgNPs via bio-reduction method using mangosteen bark extract followed by modification with p-coumaric acid (APK), and evaluating its application detecting melamine. The AgNPs were characterized through ultraviolet-visible absorption spectroscopy (UV-Vis), Fourier transform infrared absorption spectroscopy (FTIR), and X-ray diffraction (XRD). Observation suggested that an increase of incubation time had affected its surface Plasmon resonance trend. Observation of functional group by FTIR showed that carbonyl group (1707 cm-1) suspected from hydroxyl group (3414 cm-1). Further analysis of crystallite via XRD suggested that nanoparticle size at 30 nm estimated using Debye-Scherer, within the form of unit cells is cubic. Modified AgNPs showed an interaction between APK and particle surface through C=C alkenes (1598 cm-1) and aromatics (1672 cm-1), =C-H aromatic (3070 cm-1), aliphatic C-H (2501 cm-1), C-O (1107 cm-1) and C=O carboxylate (1774 cm-1). The performance of product as melamine detector suggested that the AgNPs-APK had detected melamine in range of concentration from 0.1 to 1000 ppm.

The purpose of this article is developing the optimal formulation of excipients for eye drops with tetrahydrosoline hydrochloride and researching of the locally irritating effect of the selected formulation of eye drops. The objects of the research are experimental solutions of eye drops with tetrahydrosoline hydrochloride using different combinations of excipients. Evaluation of test results in the selection of the formulation was performed according to the physico-chemical parameters of the prepared eye drops solution along with researching of stability. Assessment of the local irritation was performed on Chinchilla rabbits, particularly on the mucous membrane of the rabbit’s eye. The optimal formulation of the eye drops with tetrahydrozoline hydrochloride of a medicinal product using citrate buffer solution was developed.  The result solution represents a clear homogeneous aqueous solution to physical and chemical properties.  The developed formulation contains (in grams): tetrahydrozoline hydrochloride - 0.05; benzalkonium chloride - 0.01; disodium edetate - 0.01;  sodium chloride - 0.84; citrate buffer - to a pH of 6.2 to 6.5;  injection water - up to 100 ml. Samples of the experimental series of eye drops meet the requirements of HFC on ophthalmic drugs in terms of physico-chemical quality indicators as description, transparency, osmolality, pH of the solution, quantitative content of tetrahydrazoline hydrochloride. The results obtained in the research of stability of the eye drops experimental series throughout a long-term and accelerated storage during 6-months observation indicate the invariance of critical quality indicators, such as description, transparency, pH of the solution and the quantitative content of tetrahydrazoline hydrochloride. The results of determining the locally irritant effect on the mucous membrane of the rabbit’s eye showed that developed formulation of the eye drops does not cause any local irritation, neither visual reaction from the mucous membrane of the eye. The damaging effect level was 0 points in comparison with the other drugs. It is proved that the proposed formulation of eye drops meets the requirements of SPhU, stable and comfortable to use. The results of this experiment have a practical importance for development of new generic drugs.

Comparative morphometric analysis of different types and brands of clay powders of domestic origin for the reasonable choice of filler of polymer nanocomposite materials with improved properties. Morphometric analysis of alumina particles was performed by optical polarization microscopy. Micrographs were obtained using a digital camera with an adapter. To quantify the size of clay particles, we used the image analysis method in ImageJ program. The area, perimeter were determined, and the equivalent diameter and particle shape index were calculated. Statistical processing of the experimental data was performed using the software packages "Statistica" and "Excel". A comparative morphometric analysis of various types and grades of clay powders of domestic origin, intended for use as nanofillers in the production of polymeric composite materials with improved properties, was performed. It was found that the nature of the distribution of particles of equivalent diameter in all the studied samples is qualitatively similar, but has certain differences in quantitative indicators. The distribution of particles of the studied brands of clay powders according to the shape indicator showed a pronounced asymmetry towards its maximum values. On the basis of a detailed morphometric analysis of particles of different types of clay powders, differences in the quantitative characteristics of the particle distribution by the equivalent diameter and shape index were established. The results obtained will allow a reasonable approach to the selection of the brand of clay, which will be used as filler in the production of polymeric nanocomposite materials.
