З метою обґрунтування особливостей ремоделювання міокарда, про- водили вивчення параметрів ехокардіографії серця, стану вегетативної регуляції, психосоматичного статусу у хворих з різними формами фібриляції передсердь. Обстежено 90 хворих у віці 45-65 років. Всі па- цієнти відповідно до наявності хронічної серцевої недостатності були розподілені на групи: I група – хворі на серцеву недостатність з фібриляцією передсердь (постійна, або персистуюча форма), ( n=50). ІІ група - хворі без серцевої недостатності з фібриляцією передсердь, (n=40). III – контрольна група: 36 практично здорових осіб. Усім хворим проводили електрокардіографію, ехокардіографію, холтерівське моніторування ЕКГ, визначення варіабельності ритму серця, психологічне тестування. Згідно результатів дослідження встановлено, що наявність фібриляції передсердь навіть без вираженої структурної патології серця, ознак серцевої недостатності є фактором, що погіршує часові та спектральні показники варіабельності серцевого ритму: достовірно знижуються показники симпато-парасимпатичної модуляції, парасимпатичної активності. У хворих із хронічною серцевою недостатністю і фібриляцією передсердь найчастіше спостерігається дилатація лівого передсердя, збільшення кінцевого діастолічного і кінцевого систолічного розмірів, кінцевого діастолічного та кінцевого систолічного об’ємів лівого шлуночка, ударного об’єму, зниження фракції викиду, що свідчить про процеси ремоделювання міокарда. За результатами проведеного психологічного тестування у пацієнтів з хронічною серцевою недостатністю відмічається виражена особистісна і ситуаційна тривожність, підвищений рівень депресії, що є предиктором подальшого прогресування серцевої недостатності.
Ключові слова: хронічна серцева недостатність, фібриляція перед- сердь, варіабельність серцевого ритму, фракція викиду лівого шлуночка.

Незважаючи на поступ медичної науки, ішемічна хвороба серця залишається лідером у структурі захворюваності та смертності. Упродовж останніх десятиліть головним методом лікування гострого коронарного синдрому є проведення ургентного черезшкірного коронарного втручання (ЧШКВ) з імплантацією стенту в інфаркт-залежну артерію. Одним із ускладнень у віддаленому періоді після стентування є тромбоз стенту, який негативно впливає на виживання хворих. Метою дослідження є описати клінічний випадок раннього тромбозу стенту в хворої на гострий інфаркт міокарда та проаналізувати можливі причини згаданого ускладнення після проведення процедури ЧШКВ.Описано клінічний випадок розвитку раннього тромбозу стенту після ЧШКВ у хворої на гострий інфаркт міокарда (ІМ) та проаналізовані головні причини даного ускладнення. Хвора Ш., 65 років, поступила ургентно з попереднім діагнозом гострого коронарного синдрому. На 11 день після процедури ЧШКВ загальний стан хворої погіршився – запідозрено тромбоз стенту та проведено ургентну коронароангіографію. Відповідно до класифікації Academic Research Consortium тромбоз стента поділяють відповідно до рівня підтвердження та часу розвитку події. Клінічні чинники ризику, які сприяють розвитку тромбозу поділяють на три групи: залежні від процедури та типу атеросклеротичного пошкодження; залежні від пацієнта; залежні від антитромбоцитарної терапії. Хворі на ГКС високого ризику тромбозів, яким проведене ЧШКВ шляхом стентування, потребують ретельного моніторингу в віддаленому періоді. Наявність цукрового діабету, хронічної хвороби нирок, серцевої недостатності тощо є передумовою призначення більш потентних антитромбоцитарних засобів (тикагрелор, прасугрель) у додаток до низьких доз ацетилсаліцилової кислоти в складі подвійної антитромбоцитарної терапії.

Acenocoumarol is the most widely prescribed vitamin K antagonist (VKA)
to prevent and treat thromboembolic disorders. It keeps a major place in
many indications despite the introduction of new direct oral
anticoagulants (DOACs). However, a narrow therapeutic range, an
intra-individual variability and drug interactions may lead to serious
adverse drug reactions. Sometimes, a genetic or acquired resistance to
this drug may lead to a risky situation. Hopefully, resistance to
acenocoumarol is a very rare phenomen.
Here in we present an unsusual case of a suspected resistance to
acenocoumarol. This case was notified to the Tunisian National Center of
Pharmacovigilance on October 2017 and registered under the number
2449/2017.
A 67-year-old patient with hypertension, diabetes, and coronary disease
was treated with captopril, atenolol, atorvastatin, and salicylic acid.
In 2017, acenocoumarol treatment was introduced. At biological control,
the prothrombin time (PT) was 100%. The doses of acenocoumarol were
raised progressively with iterative controls of PT. PT was always 100%
even when acenocoumarol reached the dose of 2 g/day. A resistance to
acenocoumarol was suspected. The patient was referred to
pharmacovigilance department for case analysis. During the patient
interview, we discover that the patient was confusing acenocoumarol with
atenolol. In fact, when his doctor was increasing the doses of
acenocoumarol, the patient increased her intake of atenolol believing
that it was acenocoumarol.
A resistance to acenocoumarol was eliminated in this patient since she
had never taken the drug. We highlight through this case the importance
of patient’s interview. Explaining the indications and the potential
adverse events of the drug to patients taking VKA is crucial to ensure a
better efficiency of treatment without increasing the risk of bleeding
complication.

Published: April 2023

Currently there are still many power plants using fossil fuels, including oil, gas and coal to produce electricity. The problem recently received by many developing countries, including Indonesia, is environmental degradation due to CO, SO2 and NOx emissions. Co-burning of biomass with coal is in most countries one of the most economical technologies available today for significant pollutant reduction. This study tested the combined combustion of coal and biomass in a direct co-firing Circulating Fluidized Bed Boiler (CFBB) with two treatments, namely 5 wt% sawdust biomass and 95 wt% coal, 5 wt% woodchip biomass and 95 wt% coal. The results of the two tests were compared with the parameters when using 100 wt% coal. This study aims to (1) analyze the energy produced from burning a combination of coal and biomass, and (2) analyze the emission content, including SO2, CO, NOx. The mixture of coal and sawdust produces 82 MWh of gross electricity, higher than coal and woodchips and requires the smallest amount of fuel, namely 18.7 tons per hour. The 5 wt% woodchip emitted the lowest emissions compared to the other 2 cases, namely 71.5 mg/Nm3 SO2 and 222.4 mg/Nm3 for NOx. The lowest CO emission was issued by a 5 wt% woodchip mixture, namely 4.0 ppm.
Effect of varnish coating agent application on surface hardness of glass ionomer cement after immersion in carbonated drinks
Authors: Arsanti Natasya , Megantoro Aryo , Meidyawati Ratna 
Published: April 2023

ABSTRACTIntroduction: Glass ionomer cement is a material for treating dental caries. The disadvantage of glass ionomer cement is that if it comes into contact with acids before maturation, there will be a decrease in mechanical properties which is indicated by a decrease in surface hardness. Surface hardness has a relationship with aesthetics and resistance to scratches that can cause fractures. Coating agents like varnishes are required for glass ionomer cement to protect them from liquids with low pH level, such as carbonated drinks. Unfortunately many dentists neglected this procedure. The purpose of this research was to compare the surface hardness of glass ionomer cement which is protected and not protected by coating agent when its maturation is in contact with acids, to emphasize the importance of this procedure. Methods: This research was a laboratory experimental study. Samples consist of 24 glass ionomer cement specimens (GC Fuji IX GP EXTRA). Glass ionomer cement specimens were divided into 4 treatment groups. The first group was not applied with varnish and stored without immersion, the second group was applied with varnish and stored in artificial saliva, the third group was applied with varnish and soaked in carbonated drinks, and the last group was not applied with varnish and was immersed in carbonated drinks. The data that has been collected was processed and analyzed using the computer-based application IBM SPSS Statistics version 23.0. Results: There was a significant increase in the surface hardness of glass ionomer cement in all treatment groups. There was a significant difference in the mean surface hardness of glass ionomer cement after immersion in carbonated drinks between the groups that were applied with varnish coating agent and that without application of varnish coating agent. Conclusion: The surface hardness of glass ionomer cement restoration which was applied with varnish coating agent has a higher value compared to those not applied with varnish coating agent after immersion on carbonated drinks.Keywords: carbonated drinks, glass ionomer cement, microhardness test; saliva, varnish coating agent

Abstract

OBJECTIVE
To examine patterns of collaborative research behavior by gender among veterinary academic faculty to determine whether differences exist in how men and women access resources as a contributing factor to the advancement gap.

SAMPLE
710 faculty from 23 veterinary medical colleges.

PROCEDURES
An online questionnaire was sent through listservs at participating institutions and data were collected anonymously. Responses related to professional demographics, resources, collaboration, and elements of environmental culture were analyzed to identify associations among variables. Proportional odds logistic regression was utilized to examine the effect of gender on academic rank.

RESULTS
Male and female faculty reported participating in collaborations at equal rates. Men were more likely to engage in research collaborations with other men. These collaborations were more common than collaborations between women or between women and men. Men had 47% higher odds of more advanced academic rank compared with women and controlling for relevant factors. While there was no difference in the value of startup packages listed by men and women, women were more likely to report gender as a disadvantage in accessing resources and opportunities.

CLINICAL RELEVANCE
Research productivity is a main factor driving academic promotion. To improve gender equity in career advancement and to support scholarship among all faculty, the creation of institutional development programs focused on facilitating collaborations and resource sharing may be a strategic area for veterinary academic leaders to consider.

Authors: Yasutra Amega , Darmawan Ganesha R , Muhammad Rafki  
Published: April 2023

Well integrity failures may arise during the production phase of a well in a field. Those failures could create a Sustained Casing Pressure (SCP), a pressure that is measurable at the wellhead that can not be bled-off. SCP has to be addressed carefully to avoid any uncontrolled fluid flow to other formation or to surface. To maintain SCP value from degrading the other barrier integrity, the pressure threshold should be known and maintained for each annulus in a well. The maximum pressure threshold known as Maximum Allowable Annular Surface Pressure (MAASP).
This case study will calculate MAASP from three wells in X field using three known method as outlined in API RP90-2 and ISO 16530-1. API RP 90-2 define two methods in calculation MAASP (known as MAASP – Maximum Allowavle Wellhead Operating Pressure), Simple Derating Method (SDM) and Explicit Derating Method (EDM).
The result then compared and evaluted to know the differences, trend of MAASP for each methods, and create a generalization of MAASP/depth for field rule of thumb. For A annulus, the MAASP obtained using API RP90-2 SDM and EDM method is always greater than that obtained using the ISO 16530-1 method. However, for B annulus, the MAASP obtained using the API RP 90-2 SDM method varies, occasionally being greater or less than the ISO 16530-1 method. While in C annulus, the MAASP obtained using the API RP 90-2 SDM and EDM methods is always less than the ISO 16530-1 method. The MAASP/depth generalization will be presented for MAASP ISO 16530-1.

Published: April 2023

A naturally fractured reservoir today plays a significant role in the improved worldwide oil and gas production. More than half of the resource is mostly found in this reservoir. In this reservoir, there are two porous media: the matrix, which serves as the fluid source, and the fractures, as the fluid network that flow to the wellbore. Many authors have done the researches of works in order to modelling this reservoir. There are two model are done in this study, such as Warren and Root model, where fluid flow mechanism matrix to fractures is known as pseudosteady-state flow and Kazemi-Gilman model is known as transient interporosity flow.
Reservoir Engineers generally utilize pressure transient analysis to determine this reservoir's characteristics. The purpose of this study is to assess whether it is feasible to incorporate the parameters from the Pressure Transient analysis using a synthesis simulation model. It also aims to observe how reservoir parameters behave in relation to the characteristics of naturally fractured reservoirs by utilizing various values for porosity, permeability, and fracture spacing.

Настоящая статья посвящена раскрытию экономических последствий лесных пожаров в Республике Саха (Якутия) в течении двух пожароопасных периодов. Определены зоны контроля лесных пожаров в республике, выявлены причины возгораний, проанализированы экономические последствия лесных пожаров, рассмотрены меры профилактики для их предотвращения. Информационной базой исследования послужила статистическая обработка данных о лесных пожарах. Подсчитан экономический ущерб, составлена карта пожаров в улусах республики. Отмечено, что особо пострадавшие улусы расположены в Центрально-Якутской лесопожарной области с равнинным рельефом и характеризующуюся наличием светлохвойных лесов сухих местопроизрастаний, обладающих повышенной пожароопасностью. Выявлено отсутствие единой методики определения ущерба, причиняемого лесными пожарами. Показана прямая зависимость лесных пожаров от эффективности противопожарных мероприятий. Полученные результаты могут быть использованы в системе среднего образования при изучении предмета «Экономика», так как экономическое образование является необходимым фактором для определения связей между различными процессами и их последствиями, что ведет к формированию адекватного отношения человека к обществу.
The article studies the economic consequences of forest fires in Yakutia during two fire-hazardous periods. Forest fire control zones in the republic were identified, the causes of fires were revealed, the economic consequences of forest fires were analyzed, and preventive measures for their prevention were considered. The statistical processing of the data on forest fires served as an information base. The economic damage was calculated, a map of fires in the districts of the republic was compiled. It was established that the particularly affected districts are located in the Central Yakutia area with a flat relief and characterized by the presence of light coniferous forests of dry areas with increased fire hazard. The absence of a unified methodology for determining the damage caused by forest fires was revealed. The direct dependence of forest fires on the effectiveness of fire-fighting measures ws shown. The obtained results can be used at schools for teaching Economics, as economic education is a necessary factor for the formation of an adequate attitude of a person to the society.
