PyTheis—A Python Tool for Analyzing Pump Test Data
Authors: Chang Sun Woo , Memari Sama S. , Clement T. Prabhakar
Published: August 2021

The Theis equation is an important mathematical model used for analyzing drawdown data obtained from pumping tests to estimate aquifer parameters. Since the Theis model is a nonlinear equation, a complex graphical procedure is employed for fitting this equation to pump test data. This graphical method was originally proposed by Theis in the late 1930s, and since then, all the groundwater textbooks have included this fitting method. Over the past 90 years, every groundwater hydrologist has been trained to use this tedious procedure for estimating the values of aquifer transmissivity (T) and storage coefficient (S). Unfortunately, this mechanical procedure does not provide any intuition for understanding the inherent limitations in this manual fitting procedure. Furthermore, it does not provide an estimate for the parameter error. In this study, we employ the public domain coding platform Python to develop a script, namely, PyTheis, which can be used to simultaneously evaluate T and S values, and the error associated with these two parameters. We solve nine test problems to demonstrate the robustness of the Python script. The test problems include several published case studies that use real field data. Our tests show that the proposed Python script can efficiently solve a variety of pump test problems. The code can also be easily adapted to solve other hydrological problems that require nonlinear curve fitting routines.

The tendency that has emerged in recent years towards an increase in the number of overweight children, as well as an increase in the incidence of children associated with obesity and overweight, actualizes the timely indication of deviations in the physical development of children in order to prevent health disorders. The article provides a comparative analysis of methods for assessing the physical development of children using somatometric indicators: methods of sigma deviations (deviation from standard arithmetic mean values by the value of sigma deviation), estimates on regression scales that take into account the correlation between body weight and body length and age (deviations from the proper values from M –1 to M + 2σR), body mass index estimates by calculating the Quetelet index, using the SDS-standard deviation score, Z-score (WHO 2007) and bioimpedance analysis. The generalized analysis in the age group 12–17 revealed the highest percentage of overweight children when analyzed using bioimpedansometry (20.9 %) and when assessing BMI according to the WHO method of 21.2 % regardless of gender and significantly lower indicators when assessing with using regression scales and sigma deviations (9.6 % among boys and 18.7 % — among girls when assessed using regression scales and 15.3 %, and 11.2 % — when assessed by the method of sigma deviations). The broad capabilities of bioimpedance analysis of body composition make it possible to diagnose the presence of overweight and obesity at the individual level. Comparable results obtained in bioimpedance analysis and in assessing body mass index using the method (WHO, 2007), allow us to consider this method in population studies of indication of overweight and obesity as a rather informative method.

Published: August 2021

Purpose: Perianal fistula is one of the most common anorectal diseases in adult patients, especially men. A relationship between pyogenic perianal abscess and fistula formation is established in multiple domains. This is the first exploration of such association among patients in the country as no related study has been published in Bahrain. We expect this study to be a foundation for future protocols and evidence-based practice.Methods: A retrospective study was conducted in Salmaniya Medical Complex of Bahrain. A total of 109 patients with a diagnosis of anal abscess were included between 2015 and 2018. Data were collected from the electronic files database used in Salmaniya Medical Complex (iSeha) as well as phone calls to the patients. Collected data were analyzed using statistical software.Results: The most predominant presentation of perianal abscess was pain. Over 50% of abscesses were classified as perianal (56.9%) and among those, left-sided abscesses were more common, followed by right-, posterior-, and anterior-sited, respectively. No recurrence of abscess was recorded among 80% of patients. A fistula developed following abscess drainage in 33.9% of patients. Most fistulas (37.8%) were diagnosed within 6 months or less from abscess drainage. Posterior fistulas were the most common, followed by anterior and left-sided fistulas.Conclusion: The incidence of anal fistula in Bahrain after perianal abscess was 33.9%. Most of the patients who developed a fistula following pyogenic abscess drainage were males and above the age of 40 years. The most common site for fistula was posterior.

The dispersion of the Asian bivalve Anadara kagoshimensis in the Sea of Azov continues for more than 30 years. The study of the expansion of A. kagoshimensis is based on the materials of annual bottom grab surveys performed in the Sea of Azov in 1989-2018. The process of dispersion of the mollusk is considered through the changes of the range area, the indicators of abundance (specific abundance, biomass, total stock) and the structure of the population. The main stages of the invasion process are highlighted and discussed. The influence of various environmental factors on the distribution and quantitative indicators of the development of the mollusk population is estimated. It is shown that salinity is the key factor determining the expansion of the mollusk in the Sea of Azov.

In 2020 the first record of Wolffia arrhiza was registered in Novosibirsk Region (West Siberia) in the floodplain lake. Wolffia arrhiza formed vast stands with an area of hundreds square meters and with high productivity. Besides monodominant communities, it was met as a component of the cenoses of such hydrophytes as Stratiotes aloides , Hydrocharis morsus-ranae , as well as of the helophyte communities formed by Typha latifolia and Eleocharis mamillata . According to local residents, the large stands of Wolffia was observed for some years, thus, most likely, the population winters safely at the latitude of Novosibirsk. The most likely source of Wolffia arrhiza appearance in the lake was a deliberate introduction from the aquarium. Although the probability of this plant entering to the lake from the waste water of the city septic tank of the Novosibirsk sewage waters also exists.

El presente artículo es un balance analítico de investigaciones que tiene que ver con la lectura y la escritura en el contexto escolar, para lo cual el objetivo fue identificar y analizar investigaciones relacionadas con la lectura y la escritura de los alumnos de educación básica. De ahí que, el método empleado fue cualitativo con modalidad no interactiva, con un proceso de cuatro etapas; la primera correspondió a la búsqueda de trabajos entre el 2000 y 2018, que describieron la lectura y la escritura, las prácticas sociales y la literacidad, en el contexto escolar. Los repositorios de indagación fueron revistas especializadas como, Revista Iberoamericana de Educación, Revista Mexicana de Investigación Educativa, Perfiles Educativos, además, tesis de maestría. La segunda etapa fue, seleccionar las investigaciones tomando en cuenta la estructura, es decir, que tuvieran introducción, metodología, resultados o hallazgos y conclusiones. En la tercera etapa se agruparon las investigaciones, tratando que guardaran relación entre sí, ya sea por el objeto de estudio, por sujetos de investigación o por el contexto (escolar o sociocultural); siendo evidente que la lectura y la escritura pocas veces fue estudiada de manera simultánea. Finalmente, en la cuarta etapa, se extrajo la información esencial para ir elaborando el documento. A saber, el análisis de las investigaciones presentadas, permitieron reconocer que en las últimas dos décadas han generado diversos estudios acerca la lectura y la escritura, que existen experiencias, proyectos, materiales educativos y diferentes metodologías para su enseñanza, a la vez que los actores educativos siguen con la idea que la lectura y la escritura son codificar o decodificar letras, mismas que tienen que alcanzar los alumnos en los primeros años de escolaridad. En este sentido, las conclusiones permiten tener un balance de los documentos citados, a la vez ponen sobre la mesa hacia dónde dirigir próximas investigaciones.

В статье рассмотрена возможность применения заквасок для подавления плесневения хлеба. Целью работы являлось изучение влияния заквасок, приготовленных на чистых культурах заквасочных микроорганизмов, на скорость плесневения ржано-пшеничного и пшеничного хлебов. Исследования проводились в Санкт-Петербургском филиале ФГАНУ НИИХП в рамках темы госзадания № 2593-2014-0018 «Разработать научные основы формирования микробных композиций и биосистем на их основе, обеспечивающих высокое качество и безопасность хлебобулочных изделий». Объектами исследования являлись ржано-пшеничные и пшеничные хлеба, выработанные как с использованием заквасок, так и ускоренным способом. Для выявления влияния технологии приготовления хлеба на скорость развития плесени, проводили модельные опыты с заражением его стерильных ломтиков чистой культурой плесневых грибов Penicillium chrysogenum. В статье приведен обзор антимикробных метаболитов молочнокислых бактерий, обусловливающих их фунгицидную активность, рассмотрен механизм их воздействия на плесневые грибы. Установлено, что применение ржаной густой закваски в количестве 25 % муки в закваске имело наибольший фунгицидный эффект при хранении хлеба. Применение КМКЗ в количестве 20 % муки в закваске позволило замедлить плесневение на 1–1,5 суток по сравнению с контролем без закваски на подкисляющей добавке «Цитрасол». В результате проведенных исследований показано, что на скорость развития плесневых грибов оказывает влияние содержание уксусной кислоты в готовых изделиях, которая накапливается в процессе брожения разных видов заквасок.

The paper reviews the issues of increasing energy efficiency of support systems for formation pressure (FPS) due to the reducing non-productive power loss. For this purpose, the structure of power consumers in FPS system has been studied and the elements with the most productive power loss revealed, as well as existing methods for pump stations control and their advancement ways analyzed. The research works show that 55–60 % of non-productive power loss in oil production belong to the FPS system, and the great part of it falls within the pump units. Foremost, it is associated with non-efficient control of their operation regimes. Thereby, as the great majority of applied regulation methods is directed only to provide necessary injection capacity, power issue is not taken into account. It not only leads to the increase of power losses within the system, but also disables enhancement of prospects for control on operation regimes of pumping units. It was defined that with the method of regulation of productivity of pumping unit by changing the frequency of shaft rotation, it is possible to achieve the extension of technological options of pump station and minimize non-productive power loss as well.

Geodynamic processes, hydrocarbon migration and their occurrence in geophysics
Authors:   ", Shekerov Kh.I. ,   Oil-Gas Scientific Research Project",   Institute, Azerbaijan Republic
Published: August 2021

The paper shows that in the oil deposits formed in the Earth crust, due to the overpressure hydrocarbon components migration to the sedimentary cover and penetration to the field occur. As a result of vertical hydrocarbon migration in the oil and gas fields, a subvertical zone differing by its physical properties from the environment is formed. Such a subvertical zone affects geophysical, geochemical and logging data as well. Therefore, while migrate to the near-surface zone, hydrocarbons interact with a complex of rocks of sedimentary cover. As a result of impacting of fines forming hydrocarbons with the complex of subsurface rocks, a part of hydrocarbon flow energy transforms into the fluctuations of minor particles of subsurface rocks, and the other one, in the result of atoms and molecules impact - into the irregular molecule motion. A part of mechanical energy of moving particles transforms into another - thermal type of energy, as a result of which the environment gets “warmed”. Herewith, the temperature in near-surface zones differs from environment. Therefore, in the oil and gas fields in subvertical zones a heterogeneous area differing from the environment by geophysical, geochemical and other characteristics is formed. Based on the research data carried out by numerous specialists, it was justified that the changing of geophysical parameters is affected not only by oil-gas field, but near-surface zone as well. This feature is recommended to consider in the analysis of geophysical data.

Authors:   Institute for Oil and Gas, Azerbaijan Republic, Javadova A.S.
Published: August 2021

Aromatic hydrocarbons in the oils of Absheron and Baku archipelago, as well as in coastal zones have been identified via the method of chromato-mass-spectrometry. Geochemical estimation of distribution character of main biomarkers and their correlations as well is presented. The similarity in the distribution of monoaromatic and triaromatic steroid hydrocarbons, as well as benzogopane and sekabenzogopans has been specified, which suggests that studied oils are associated with one source rock or organic facies. The varieties observed in the distribution of saturated steranes are most likely the result of differences in the values of thermal maturity or the processes of secondary alterations.

The paper presents scientific basis of development of nanobentonite and the results of investigations using progressive research methods as well. The researches were carried out on bentonite upgrading obtained from Alpout field of Gazakh region and its properties studied. It has been defined that the mass content of bentonite may be increased from 70 up to 97 % via content cleaning from foreign substances, while the size of bentonite particles comprise 85-130 nm, and after upgrading 8-10 nm. Moreover, if the size of montmorillonite and bentonite crystalls in the initial sample were 13.3-19.5 nm, after upgrading process they were within 8.3-10.0 nm. The process of bentonite swelling has been studied. It was specified that the swelling of both raw and upgraded bentonite takes place in two stages. More intensive swelling of upgraded bentonite was observed in both stages. It was justified that the relations occurred via metal ions (cations) in interlayer distance with oxygen atoms contained in montmorillonite molecule are broken down due to the hydration process.

Published: August 2021

The elimination of complications occurred due to the hydrodynamic pressure at the wellbore during the running of the casing is one of the hardest tasks. During the well drilling in geologically complicated fields using drilling mud with 1800–2000 kg/m3 density, hydraulic fracture of the reservoir takes places while running of the casing due to the hydrodynamic pressure at the wellbore. This, in its turn, leads to the intensive drilling mud loss. To prevent such cases, it is necessary to have ra<0.65 coefficienct in well structure selection. This rate is the relation of well outer diameter to the wellbore diameter.

The history of formation and development of additives to lubricants
Authors:   Institute for the Chemistry of Additives, Azerbaijan Republic, Naghieva E.A.
Published: August 2021

The technological development led to the substitution of vegetable and animal oils for the mineral ones. With further development of engine manufacturing, the requirements to the quality of lubricants increased. It was revealed that the mineral oils, as though they are cleaned, do not satisfy the requirements. In this regard, the new method for the improvement of the quality of lubricants is the addition of organic compounds with various functional groups providing the lubricants with set properties into so-called “additives”. In 1945 on the offer of academician U. Mammadaliev a laboratory of the lubricants and additives had been established and leaded by academician A.M. Kuliev under AzNIINP named after V.V. Kuybyshev. Fundamental studies of this staff were considered a basis for the development of industrial production of efficient additives in the former Soviet Union. First developments of the staff related to the depressor and detergent, afterwards to the multi-functional additives. Based on carried out surveys by the laboratory staff the first local additives – depressors AzNII, AzNII-4, AzNII-5, AzNII-TSIATIM etc. have been developed in Azerbaijan. The success of the staff in the studies and developments, as well as the presence of qualified specialists in the chemistry of additives promoted the establishment of the single in our country profiled Institute for the chemistry of additives of the Academy of Sciences of Azerbaijan SSR under the leadership of A.M. Kuliev in 1965. The diapason of fundamental works, enabling to develop the scientific basis of synthesis of efficient additives of optimum structure has been dramatically increased. Numerous efficient additives of various purpose have been obtained. The lubricants are being used in all spheres of the economy.

Public organizations are expected to be able to manage their resources with adequate internal controls, to suppress the increase in cases of corruption due to misuse of assets. This research is a qualitative descriptive research conducted at GKI Tegalrejo Salatiga by collecting primary data from interviews with informants. The information obtained then processed by data reduction techniques, data presentation, and drawing conclusions. The results show that there is still a risk of theft of cash in the income cycle at GKI Tegalrejo, but it can be mitigated by controlling practices according to the concept of COSO. Some of the obstacles encountered in implementing this internal control include the church council not being fully able to understand the Tata Laksana Gereja, the absence of Standard Operating Procedures (SOP), lack of supervision on CCTV monitor, and lack of the function of the priest as a supervisor. This research is expected to be able to encourage congregational participation to assess the practice of internal control at GKI Tegalrejo Salatiga, serve as evaluation material for the GKI Tegalrejo Salatiga council to improve its internal control, and for academics,it is hoped that this research can become a reference in developing next researches.Keywords: internal control, theftof cash, income cycle

Background: Chronic obstructive pulmonary disease (COPD) is characterized by chronic respiratory symptoms. The respiratory symptoms of patients with acute exacerbation of COPD (AECOPD) worsen rapidly. At present, traditional western medicine treatment can not effectively alleviate the symptoms and attack frequency of patients. Suzi Jiangqi decoction(SZJQ) has a good clinical effect in the treatment of AECOPD. Due to the lack of evidence-based medicine, it can not provide an effective systematic evaluation for the treatment of AECOPD with Suzi Jiangqi decoction. Therefore, it is necessary to provide high-quality evidence evaluation for the clinical efficacy and safety of Suzi Jiangqi Decoction in the treatment of AECOPD. Methods: Two researchers independently retrieved randomized controlled trial (RCT) and quasi-RCTs of SZJQ in the treatment of AECOPD from databases including PubMed, Web of science, the Cochrane Library, CBM, CNKI, Sinomed, VIP and WanFang.The included studies were evaluated for quality according to the RCT quality assessment method provided by Cochrane Reviewer's Handbook 5.3.Review Manager 5.3 software provided by the Cochrane collaboration was used for meta-analysis. Results: This study will provide systematic review on the efficacy and safety of SZJQ as adjuvant therapy in patients with AECOPD by rigorous quality assessment and reasonable data synthesis. Conclusions: This systematic review will provide the good evidence currently on SZJQ as adjuvant therapy in patients with AECOPD.

Obezitatea reprezintă o problemă de sănătate publică, cu o creştere impresionantă a prevalenţei în ultimele de_cenii, populaţia pediatrică înscriindu-se în aceste caracteristici. Printre complicaţiile multiorganice asociate obezităţii se numără şi patologia respiratorie legată de somn. Asocierea apnee obstructivă de somn – obezitate este suspectată anamnestic la un copil care sforăie, prezintă fragmentarea somnului şi pauze respiratorii, patologia respiratorie fi ind obiectivată prin polisomnografi e. Apneea obstructivă de somn prezintă numeroase complicaţii (multe dintre ele augmentate prin asocierea obezităţii) – cardiace, metabolice, neurocognitive, ce afectează ca_litatea vieţii. Tratamentul constă în scădere în greutate, adenoamigdalectomie şi folosirea ventilaţiei de tip CPAP.
UN CAZ RAR DE SINDROM HUNTER – PREZENTARE DE CAZ

Mucopolizaharidozele (MPZ) sunt un grup de boli genetice rare din marea familie de boli lizozomale. Tulburările (MPZ) sunt cauzate de o deficienţă în activitatea unei enzime lizozomale specifice necesare pentru degradarea glicozaminoglicanilor (GAG). MPZ tip II, numită şi sindromul Hunter, constă dintr-un deficit al unei enzime, iduronat-2-sulfataza. Vă prezentăm un caz rar de sindrom Hunter cu prezentare atipică. Este vorba despre un băiat de 2,7 ani, care s-a prezentat la Clinica Pediatrie I cu simptome de infecţie a tractului respirator, cu antecedente de multiple infecţii ale otice şi respiratorii. Examenul clinic e evidenţiat: statură mare, moderat supraponderal, dismorfism facial (caracteristici faciale grosiere, frunte proeminentă, nas lărgit şi deprimat), degete mici butucănoase, cu flexie a articulaţiilor interfalangiene distale, rigiditate articulară, abdomen proeminent cu hernie ombilicală, hepatomegalie şi splenomegalie, precum şi uşor retard mental. Aspectul clinic a fost sugestiv pentru MPZ tip I, II sau VII. Dozarea enzimelor cu rol în metabolismul mucopolizaharidelor lizozomale a relevat un nivel scăzut al iduronat-2-sulfatazei, modificari caracteristice pentru MPZ tip II. Diagnosticul enzimatic a fost confirmat prin analiza ADN-ului molecular care a arătat o mutaţie a genei hemizigote iduronate-2-sulfatazei la nivelul intronului 3 (c.419-2A>G). S-a instituit terapia de substituţie enzimatică genetic recombinată de iduronat-2-sulfatază (Elaprase®). Evoluţia cazului, după aproape doi ani de tratament cu Elaprase este favorabilă, fără pierderi ale achiziţiilor neurologice.

Obesity is a public health problem, with an important increase in prevalence in the last decades, pediatric population also fits these characteristics. Among the systemic complications of obesity is included the sleep – related respiratory pathology. The association obstructive sleep apnea – obesity is suspected in a child who snores, has sleep fragmentation and breathing pauses, but the diagnosis is confirmed using polysomnography. Obstructive sleep apnea has many kinds of complications (increased by the association with obesity) – cardiac, metabolic, neurocognitive, all of them affecting the quality of life. The treatment of obstructive sleep apnea includes weight loss, adenotonsillectomy and CPAP ventilation.

Very early onset and early onset schizophrenia – which manifest themselves before the age of 13 (the first) and 18 (the latter) – represent a little explored nosological entity, which entails a genuine diagnostic challenge, considering the specificities of young age. At the same time, childhood and adolescence onset schizophrenia intertwines with a series of neurocognitive development disorders, comprising an important genetic susceptibility. The entire context of its emergence, the difficulty of detecting psycho-productive symptoms during early childhood, the severity of symptoms and the chronicization impose a rigorous diagnostic behavior and a multidisciplinary approach for optimal long-term therapy and for the socio-professional integration of patients. This paper aims at synthesizing the literature review, which may represent a starting point for ample future research; the purpose is to create specific guides on childhood and adolescence schizophrenia.
