Published: December 2023

Bu çalışma, seçim manipülasyonunun ve siyasal şiddetinin bir alt türü olan seçim şiddeti kavramının genel hatlarından hareketle 1960-1980 dönemi Türkiye siyasetinin seçim şiddeti karakterini ortaya koymayı amaçlamaktadır. Açık arşiv kaynaklarının temel veri toplama aracı olarak kullanıldığı çalışmada, askerî müdahaleler sonrası ilk genel seçimlerde devletin, seçim şiddetinin temel uygulayıcısı olduğu görülmüştür. Devletin ordu, yargı ve kolluk güçleri eliyle; baskı, tehdit, tutuklama ve askerî duruş sergileme olarak dört farklı seçim şiddeti tipinin uygulayıcısı olduğu saptanmıştır. Ayrıca, öğrenci gruplarının ve STK’ların başrolde olduğu seçim şiddeti eylemlerinde, sağ-sol siyasal kutuplaşmasını temsil eden siyasal partilere ve partilerin sivil taraftarlarına yönelik fiziksel saldırıların öne çıktığı; bunun yanında ateşli silah ve patlayıcı madde kullanımının da tercih edildiği tespit edilmiştir.
PROTEST PARADIGM IN ETHNIC RIOTS NEWS (FRAMING ANALYSIS OF PAPUANS’ STUDENT DORMITORY RIOTS IN SURABAYA ON TABLOID JUBI (JUBI.CO.ID) IN AUGUST 2019)
Authors: Suci Putri Laksmi Nurul , Monggilo Zainuddin Muda Z
Published: December 2023

In August 2019, the conflict between Papuan students and police happened in the Papuan students' dormitory in Surabaya, caused by misconceptions of information between both parties. This conflict triggered more riots in several cities, acts of racism, violence, and internet access blocking in Papua's region. Each media has its own frame and depiction of the purpose of this conflict. In the media, as a minority, Papuan students are depicted in different ways than usual. Therefore, this study aims to examine the depiction and frame of the Papuans' student dormitory riot that is reported on Tabloid Jubi (jubi.co.id) as ethnic minority media. This article uses eight pieces of online news from Tabloid Jubi (jubi.co.id), which will be analyzed using Pan and Kosicki framing analysis. In addition, this article also uses the concept of the protest paradigm from McLeod and Hertog (1998) to examine the tendency of how Tabloid Jubi (jubi.co.id) depicts information about riots. The result shows that Tabloid Jubi (jubi.co.id) tends to use three out of five characteristics in the concept of the protest paradigm, which are news frames, invocation of public opinion, and demonization.

Authors: Kaloka Rintulebda Anggung
Published: December 2023

In previous research, the discussion of public relations practices only existed at the level of government public relations, the private sector and public relations consultants as part of organisations that are outside the community itself, so the discussion of the application of public relations practices carried out by micro communities has not been widely published. The purpose of the study in this research is to provide an overview of the application of public relations practices carried out by micro-scale community structures and their relation to community development of the surrounding community. The subject of this research is the management of RT 03/RW 14 Puri Delta Asri who owns the Gulita Production YouTube channel. The method used is an in-depth interview with the head of the neighbourhood. The results of this study found that the YouTube platform can be a medium that strengthens community engagement in the community.

Authors: Jann Leite Bruna , Kehrwald Zimmermann Nilo Eduardo , Duarte Ferreira Vera Lúcia , Dias Fernando Luis
Published: December 2023

O crescimento da demanda por água potável vem aumentando gradativamente e consequentemente a necessidade de melhorias no tratamento também. Um dos fatores determinantes da qualidade da água potável, tanto no ponto de vista de saúde quanto no ambiental, é a quantidade de coagulante utilizada no processo de tratamento da água, visto que a dosagem pode variar de acordo com características físico-químicas da água bruta. Neste sentido, este trabalho apresenta o desenvolvimento inicial de um modelo capaz de predizer quantidades de coagulante para um determinado volume de água bruta, contemplando como variáveis independentes características específicas da água. Adotou-se como estratégia metodológica a análise de regressão linear múltipla realizada via software R em três etapas principais: coleta e separação dos dados, modelagem e validação do modelo. Os dados foram disponibilizados pela empresa CORSAN/RS, com recorte temporal do ano de 2015 a 2019 correspondentes a duas cidades. Os resultados mostraram a existência de uma relação estatisticamente considerável entre a variável dependente, consumo do coagulante (sulfato de alumínio) e as variáveis independentes (turbidez, cor, alcalinidade, matéria orgânica e volume aduzido). O valor de R² ajustado de 0,95 indica que modelo de predição está estatisticamente satisfatório. Ou seja, as facilidades de ajuste aliadas ao bom desempenho dos fenômenos estudados mostra que o modelo apresentado inicialmente pode ser aplicado para melhorar os processos de tratamento de água em estações de porte e processos similar.
On crescent-shaped objects of the early Bronze Age in southern Siberia and the surrounding areas
Authors: Wang Peng
Published: December 2023

Crescent-shaped objects are a special type of artifact commonly found among early Bronze Age archaeological cultures in southern Siberia and the surrounding areas. Based on typology, burial context, and accompanying assemblages, in addition to related iconographic evidence, this study shows that these crescent-shaped objects, in the form of single or double birds, were religious representations once suspended from sacred attire. Crescent-shaped objects in southern Siberia and the surrounding areas might have originated in the Baikal region during the first half of the third millennium BCE, and likely began to influence regions of northern China toward the end of the third or the beginning of the second millennium BCE.
Research on the pottery decorations and manufacturing techniques of the Houtaomuga Phase I culture
Authors: Li Penghui , Wang Lixin
Published: December 2023

The Houtaomuga Phase I culture represents the earliest Neolithic remains found in Northeast China heretofore, thus filling an over 10,000-year gap in early pottery distribution. Pottery decorations and manufacturing techniques from this culture are unique. The pattern application methods seen are stamping, rolling, and incising. The emergence of flat-bottomed pottery and coiling techniques serves as a prelude to the later ceramic tradition of cylindrical jars with flat bottoms. Comb-teeth decorations along with plant fiber temper indicate similarity with pottery remains in Eastern Siberia and the Russian Far East.
A comprehensive approach of evolving electric vehicles (EVs) to attribute “green self-generation” – a review
Authors: De Debalina , Das Uttara , Nandi Champa
Published: December 2023

The population growing faster than before, and availability of transportation options is increasing. Automobiles require combustion engines, which require fuel obtained from underground storage. This underground fuel storage is limited and depleting day-by-day. Many nations have set deadlines up to 2040 to stop producing automobiles that run on underground fuels. Researchers have concentrated on alternative modes of fuel for transportation. The world’s largest Sedan marketplaces will transition to all-electric vehicles by 2035, providing a glimpse of greener future other than a significant financial prospect. Not only Sedan, the entire world is focussing on only green electric vehicles to maintain sustainability. However, electric vehicle charging stations are operated by using many conventional resources. Therefore, this paper aims to show how self-charging electric vehicles can help to reduce emissions caused by the direct use of conventional resources in charging stations along with the up-to-date status quo of the EV market. The key descriptions of electric vehicles on top of the battery’s type which is randomly used in EVs, how the batteries are proficient in preserving and supplying power continuity itself in vehicles are talked about. Finally, the paper is consulting about charging-discharging system of electric vehicles to make the environment cleaner.
Climate Change, Compensation and Unpredictable or Uninsurable Loss: A Possible Path Forward Using Compensation Funds
Authors: Watts Kim , Vansweevelt Thierry , Weyts Britt
Published: December 2023

Climate change has created existential challenges for current models of natural hazard insurance, and it may be difficult going forward for these models to consistently, fairly and coherently manage the compensation challenges associated with climate change impacts in Europe. This paper analyses the application of a comprehensive no-fault compensation fund framework to the problem of presently uninsured and technically uninsurable losses that are currently inadequately covered by other compensation mechanisms, and for which compensation may be difficult to recover using tort law mechanisms. The proposed structure includes consideration of the purpose and form of the fund, eligibility and categories of loss covered, quantum of compensation, and funding sources. There is also a preliminary consideration of the impact of such a fund on questions of liability. The proposed model illustrates potential ways for a compensation fund to support and complement existing compensation structures such as insurance and civil liability, and provide the necessary stabilisation in European society. Further legal research in this area will require qualitative and quantitative empirical data on how existing compensation frameworks (including innovative insurance instruments like parametric insurance) have so far positively and negatively impacted the ability of victims of climate change to prepare for and recover from loss incidents, in comparison with tort law and existing insurance.
The association between obesity and the success of trial of labor after cesarean delivery (TOLAC) in women with past vaginal delivery
Authors: Shalabna Eiman , Kedar Reuven , Assaf Wisam , Nahshon Chen , Kugelman Nir , Lavie Ofer , Sagi-Dain Lena
Published: December 2023

Objectives

To evaluate the effect of overweight (body mass index; BMI 25.0–29.9 kg/m2), and obesity (BMI>30 kg/m2), on the success of trial of labor after cesarean delivery (TOLAC), with consideration of successful past vaginal birth.

Methods

This retrospective cohort study was performed using electronic database of obstetrics department at a university-affiliated tertiary medical center. All women admitted for TOLAC at 37–42 weeks of gestational age, carrying a singleton live fetus at cephalic presentation, with a single previous low segment transverse cesarean delivery between 1/2015 and 5/2021 were included. Primary outcome was the rate of cesarean delivery during labor, and subgroup analysis was performed for the presence of past vaginal birth.

Results

Of the 1200 TOLAC deliveries meeting the inclusion criteria, 61.9 % had BMI in the normal range, 24.6 % were overweight (BMI 25.0–29.9 kg/m2), and 13.4 % were obese (BMI of 30 kg/m2 and over). Using a multivariate analysis, BMI≥30 kg/m2 was associated with increased risk of cesarean delivery compared to normal weight. However, in the subgroup of 292 women with a history of successful vaginal birth BMI did not affect TOLAC success.

Conclusions

BMI does not affect the success of TOLAC in women with previous vaginal birth. This information should be considered during patients counselling, in order to achieve a better selection of mode of delivery and higher patients’ satisfaction.

Materiality of Plaster Vessels: The Problem of Southwest Asian Neolithic White Ware
Authors: Nilhamn Bonnie
Published: December 2023

The study of plaster vessels, white ware, from the Late Neolithic Southwest Asia (7000–5000 cal BC) is an untapped source that can provide us with valuable insights into the earliest development of pyrotechnology and Neolithic society. This plaster material is not well known and has not been involved in many studies. Using a symmetrical approach for the case study of plaster ware at Tell Sabi Abyad in Upper Mesopotamia, this article argues that it is crucial to acknowledge materiality in the study of these vessels. The ware resembles pottery in shape, typology, and basic function but is far from it material-wise and in its chaîne opératoire. The material plaster is also often misunderstood and associated primarily with architecture. Therefore, plaster ware stands at the crossroads between being observed as a copy of ceramics and being recognized as portable architecture. This article calls for an interdisciplinary approach, balancing the exact sciences of archaeometry and the theory of materiality. It will also address problems concerning terminology; it proposes replacing the term white ware with “plaster ware” as the most appropriate title for this ware because it can be better understood by a wider audience outside the discipline.
Interval models for uncertainty analysis and degradation prediction of the mechanical properties of rubber
Authors: Yin Shengwen , Lu Yawen , Bai Yu
Published: December 2023

As rubber is a hyperelastic material, its nonlinear deformation behavior during aging is significantly influenced by various factors, including the material characteristics, demonstrating a significant uncertainty. Most of the existing uncertain prediction methods of rubber nonlinear property degradation are based on the probability density function, which requires a large number of samples to obtain the probability distribution and requires a lot of work. Therefore, the interval model is used in this study to characterize the uncertainty. However, the traditional interval constitutive models ignore the correlation between interval variables, and the prediction results have large errors. In order to minimize prediction errors and improve prediction accuracy, an interval Mooney–Rivlin (M–R) correlation model that considers the correlation between parameters was established. To address the influence of uncertainties, an interval Arrhenius model was constructed. The M–R model requires multiple fittings of stress–strain curves to obtain the model parameters, and the prediction process is relatively complex. Therefore, combing the two proposed models, the relationship equations of rubber tensile stress with aging temperature and aging time were first established by interval Arrhenius, and then the interval M–R model was used to obtain the variation ranges of parameters

. By contrasting this with the measured rubber aging information, the effectiveness of the proposed model was confirmed. Compared with the prediction model based on the average value, the maximum error of prediction of this model is reduced by about 60%. Compared with the traditional interval model, the prediction region is significantly reduced, which further improves the prediction accuracy. The above results indicate that this interval aging lifetime prediction model is suitable for characterizing the nonlinear stress–strain behavior of rubber-like elastomers.

Long-acting injectable antiretroviral therapy (LA-ART) expands treatment options for people living with HIV (PLWH). This qualitative study characterizes LA-ART awareness, perceptions, and preferences among PLWH engaged in HIV care. From 2019 through 2021, we conducted semistructured in-depth interviews with 71 PLWH sampled from three clinics in three U.S. settings (North Carolina, Washington, DC, Massachusetts). Transcripts were analyzed using narrative and thematic techniques. Participant mean age was 46 years (range 24–72); most were cisgender men (55%) and virally suppressed (73%). Most participants had not heard of LA-ART and reacted with a mix of excitement and cautiousness. Potential LA-ART benefits included easier adherence, privacy, and effectiveness; concerns included effectiveness, side effects, costs, and increased clinic visits. Participants appreciated that LA-ART could support achieving and sustaining viral suppression. To inform their decision, participants wanted more information and convenient access and administration. Findings indicated that a shared decision-making approach and economic and logistical support for PLWH could facilitate LA-ART uptake.

Authors:   Institute of Europe, RAS, Belov Vladislav
Published: December 2023

Since the end of the zero years in Germany, the shortage of skilled labor has been increasing. Its lack reduces the competitiveness of the German socio-economic space. One of the ways to solve the problem, the state considers the attraction of workers from abroad. Attempts by four governments under the leadership of A. Merkel to change the situation on the labor market in this way, including the adoption of the relevant relevant law, were unsuccessful. The new Cabinet of Ministers has prepared A new concept, on the basis of which comprehensive changes to the legislation on the immigration of qualified specialists have been developed. The author analyzes the causes of the labor shortage, migration dynamics over the past decade, the country structure of foreign workers in the German labor market. He pays special attention to the study of the current state of vacancies and the professional structure of the unemployed corresponding to them; In this context, examines the amendments to the above-mentioned immigration law adopted in June 2023 and assesses the prospects for its implementation, as well as the national economic risks associated with it.

¿Por qué más educación no conduce necesariamente a la reducción de la pobreza?
Authors: A. Baquen Carolina
Published: December 2023

A finales del siglo XX, los economistas colombianos identificaron un fuerte vínculo entre la educación y la reducción de la pobreza. Sin embargo, a pesar de una importante expansión de la cobertura educativa, los niveles de pobreza no han disminuido como se preveía. Este problema se extiende más allá de Colombia y ha impulsado el desarrollo de teorías económicas, centradas en factores como la deserción escolar temprana, las imperfecciones del mercado, el aumento de la incertidumbre y los costos de la educación, todos los cuales contribuyen al enigma de las trampas de la pobreza. Métodos: Utilizando un enfoque cuantitativo, la investigación analiza la relación entre los logros educativos, las oportunidades de empleo y los antecedentes socioeconómicos de la población más joven. Además, explora los motores de la desigualdad en el mercado laboral, haciendo especial hincapié en las divisiones de clase social y en el papel de las redes sociales a la hora de configurar el acceso al empleo. Resultados: Los resultados preliminares ponen de relieve una desconexión persistente entre el aumento de la educación y la integración en el mercado laboral de los jóvenes más pobres de Colombia. El estudio identifica una clara asociación entre la segregación de clase social y el acceso diferencial al empleo, acentuando el papel influyente de las conexiones sociales en la obtención de oportunidades laborales. Conclusiones: Esta investigación desvela las complejidades que rodean a las trampas de la pobreza en Colombia, dilucidando por qué la mejora de la educación no se ha traducido en la esperada reducción de la pobreza. Subraya la necesidad imperiosa de examinar en profundidad los retos políticos a los que se enfrenta el país. Al abordar las barreras de acceso al mercado laboral para los más vulnerables, este estudio contribuye significativamente al discurso más amplio sobre la intrincada relación entre la educación y la reducción de la pobreza en Colombia. Las conclusiones también son pertinentes para otros países que se enfrentan a retos similares, y ofrecen valiosas perspectivas tanto a los responsables políticos como a los investigadores.

The Effect of Transfusion and Hypoxia on Cells in an in vitro Model of the Neurovascular Unit
Authors: Ivkin A. A. , Grigoriev E. V. , Khilazheva E. D. , Morgun A. V.
Published: December 2023

Up to 57% of patients develop postoperative delirium after surgery for congenital heart defects (CHD). To reduce cerebral damage in pediatric patients during CHD surgery it is important to find out what inflicts the worse damage: would it be a systemic inflammatory response (SIR) triggered by transfusion, or hypoxia developed in non-transfused patients? In vitro evaluation of hypoxia and SIR effects on the neurovascular unit (NVU) cells might contribute to finding the answer.

The aim of the study was to compare the effect of varying severity hypoxia and SIR on the functional activity of NUV cells in vitro.

Materials and methods. An in vitro NVU model was designed including neurons, astrocytes and endotheliocytes. The effect of hypoxia on NVU was evaluated in the control (C) and 4 study groups (H 1–4), formed based on O₂ content in the medium. The C group NVU were cultivated in standard conditions: N₂ — 75%, O₂ — 20%, CO₂ — 5%; H1: N₂ — 99%, O₂ — 1%; H2: N₂ — 98%, O₂ — 2%; H3: N₂ — 97%, O₂ — 3%; H4: N₂ — 96%, O₂ — 4%. The significance of the differences was 0.0125. The effect of interleukin-6 (IL-6) content on NVU was measured by adding to culture medium pediatric patients’ serum with known minimal or maximal SIRS-response. The assessment was made in the Control — an intact NVU model, and 2 study groups — «Minimum» and «Maximum», i. e. samples with minimum or maximum IL-6 content in culture, respectively. The significance of the differences was 0.017. The cells were incubated at a normothermia regimen for 30 minutes. Then, the functional activity of NVU cells was evaluated by measuring transendothelial resistance (TER) for 24 hours and Lucifer Yellow (LY) permeability test at 60 and 90 minutes after the start of the experiment.

Results. After incubation under hypoxic conditions, TER changes occurred in all studied groups. However, they were statistically significant only in the group with 1% oxygen content in the medium. TER decrease in this group was observed after 2, 4 and 24 hours. LY permeability also changed at 60 and 90 minutes, similarly — in NVU cultivated with 1% oxygen in the medium. Minimal TER values were documented at 4 hours after patients’ serum was added to NVU cells culture medium, and TER increased at 24 hours in both study groups. Cellular permeability to LY changed significantly after 1 hour exposure in both groups — with minimum and maximum IL-6 content in the medium. Although at 90 minutes, there was no difference between the 3 groups in LY permeability tests.

Conclusion. Intensive SIR demonstrated short-term but more deleterious than hypoxia, effect on cells in the NVU model. Hypoxia disrupted functional activity of NUV cells only at 1% O₂ concentration in the medium.

De las guerras con Francia, Italia y San Quintín (I)
Authors: Bustamante García Agustín
Published: December 2023

Las guerras entre Enrique II de Francia y Carlos V y Felipe II tuvieron gran repercusión gráfica; los episodios italianos de Parma, Siena y Nápoles forman parte de los grandes conjuntos pictóricos y escultóricos del siglo XVI, obras de artistas renombrados como Giorgio Vasari o el flamenco Giovanni Stradano. Los grabados divulgaron los acontecimientos más destacados casi al unísono en que ocurrieron, como es el caso del cerco de Mirandola, las defensas de Roma representadas por Lafreri, Nettuno, Ostia, Vicovaro y Civitella del Tronto. Los acontecimientos se representan como corografías en las que suceden los episodios bélicos. Son reproducciones fieles de los hechos militares, auténticas crónicas gráficas muy valoradas por los contemporáneos, algunas de las cuales se reproducirán muchas veces después de los hechos.

Purpose: secondary oligomenorrhea, characterized by infrequent menstrual cycles, is a significant concern in women's reproductive health. Understanding the multifaceted determinants of this menstrual disorder is essential for developing effective interventions and improving women's well-being. This study aims to comprehensively investigate the interplay between diverse temperature living conditions, stress levels, and sleeping duration in relation to secondary oligomenorrhea. Material & Methods: to achieve our objectives, we conducted a cross-sectional survey involving a diverse cohort of women aged 18 to 23 years, all of whom had experienced secondary oligomenorrhea. We employed a carefully crafted questionnaire to collect extensive data on various aspects, including demographic information, menstrual history, exposure to different temperature conditions, and sleeping patterns. Subsequently, the collected data underwent statistical analyses, including correlation and regression analyses, to unravel the intricate associations between temperature, stress, sleeping duration, and secondary oligomenorrhea. Results: the study unveiled intriguing correlations across a spectrum of temperature conditions and identified a consistent negative correlation between sleeping duration and menstrual cycle length, regardless of temperature fluctuations. This finding suggests that longer sleeping durations are associated with slightly shorter menstrual cycles. However, the impact of stress on secondary oligomenorrhea displayed variability depending on temperature conditions, indicating a more complex relationship. Conclusion: this investigation significantly enhances our understanding of how diverse temperature living conditions, stress levels, and sleeping patterns collectively influence secondary oligomenorrhea. While the observed correlations are of moderate strength, they underscore the intricate and multifaceted nature of menstrual cycle regulation. These findings emphasize the need for a holistic approach when addressing secondary oligomenorrhea, considering factors beyond temperature, stress, and sleeping duration.

This research investigates functional strength ratios in young elite athletes across different sports disciplines with different movement characteristics, focusing on the relationship between these ratios and physical performance. Purpose: the study aims to examine the differences in functional ipsilateral and bilateral strength ratios among athletes in symmetrical, asymmetrical, and hybrid sports and assess how these disparities impact strength parameters. Material & Methods: the study comprised 56 male athletes aged 18-28, excluding those with lower limb injuries or limitations affecting performance. The participants were divided into symmetrical, asymmetrical, and hybrid sports categories. Strength assessment utilised an isokinetic dynamometer, focusing on quadriceps-to-hamstring strength and bilateral strength ratios. The study employed MANOVA as the major statistical test for the purpose of the study. Results: athletes in asymmetrical sports demonstrated higher bilateral symmetry in knee extensors compared to symmetrical (0.94±5.98) and hybrid sports (4.9±10.32), with values of 12.89±8.56. The functional hamstring to quadriceps (H:Q) strength ratio showed lower ratios in hybrid sports (right limb: 0.60±0.12, left limb: 0.61±0.09) compared to symmetrical (right limb: 0.79±0.16, left limb: 0.94±0.27) and asymmetrical sports (right limb: 1.05±0.26, left limb: 1.03±0.24), yet within normative values. These findings suggest that sport-specific demands significantly influence functional strength ratios, highlighting the importance of tailored training and rehabilitation programs. The observed strength asymmetries, particularly in sports with unilateral movements, underline the need for sport-specific training approaches to address these imbalances. Conclusion: the study revealed that sport-specific training can lead to strength asymmetries within normal ranges, suggesting that they may not substantially induce muscular imbalances. However, the distinct H:Q ratio patterns in hybrid sports emphasise the need for customised training and rehabilitation strategies.

Purpose: the purpose of this study was to evaluate the effect of diclofenac sodium gel phonophoresis in grade -l ankle sprain. Materials & Methods: 54 patients were randomly included in this study and allocated equally into two groups. Group-1 was managed with therapeutic ultrasound (digital ultrasound machine, a product of HMS marketed in India with frequency of 1 MHz and 3MHz) with diclofenac sodium gel and group-2 was managed with therapeutic ultrasound with aquasonic gel. Therapeutic ultrasound with diclofenac sodium gel, marketed under the name of Voltaren, was administered at a frequency of 1MHz, an intensity of 0.8 W/cm2 with continuous mode (1:1) for five times a week for 2 weeks. The patients were examined by using Numeric Pain Rating Scale (NPRS) and Foot and Ankle Disability Index (FADI). They were assessed on the baseline, after 1st week, and after 2nd week of treatment. Results: one way ANOVA test was used to determine the significant difference at the 0.05 level of significance. There was reduction in NPRS and FADI p-value 0.000 after 2nd week of treatment in group-1 and group-2. But on the basis of mean difference score of NPRS and FADI, group-1 was better effective in terms of reduction of pain and improvement of function periodical manner (Table 3). Conclusion: significant dose-dependently relief was observed in NPRS and FADI for pain in disability for each group treated with diclofenac sodium gel compared with aquasonic gel using ultrasound. Acoustic streaming increased these benefits significantly when used after topical application of diclofenac sodium gel, and the dose-dependent effects of diclofenac sodium gel using therapeutic ultrasound.

Background: Necrotizing enterocolitis (NEC) is a serious gastrointestinal disease of neonate with high fatality. GutCheckNEC scoring system can be used in predicting NEC and decrease NEC rate. Aims: To assess risk factors and use scoring system GutCheckNEC in predicting necrotising enterocolitis. Methods: A prospective observational study with preterms, birth weight <1500grams was done. Risk factor assessment was done using GutCheckNEC and serial scorings were done. Descriptive analyses of the various risk factors assessed were done. Results: 51 babies included, with gestational age 24 to 35 weeks (Median (IQR) 30+2 (27+2, 31+6), birth weight 500 to 1500 grams (Median (IQR) – 1105 (893, 1300). 9 NEC cases, 6(11.5%) confirmed NEC and 2(22%) were surgical NEC. Absence of ANS, HsPDA and late onset sepsis were risk factors. The median (IQR) scoring at 72 hrs., 86 hrs., 7 days, 14days, 21days and 28 days were 34 (31, 38), 34 (30, 39), 34 (26, 43), 31 (23, 35), 35 (23, 38), 35 (30, 40). The median risk for developing NEC was high (33-36) on all days except day 14, when it was moderate (20-32). The sensitivity and specificity for a cut off >32 at 86hours was 85.7% and 48.5% (PPV – 26.1%, NPV – 94%) for medical NEC and 100% and 44.7% (PPV – 8.7%, NPV – 100%) respectively for surgical NEC. Conclusion: Hence we conclude that GUTCHECK can help in early prediction of NEC and prevention of NEC.

The purpose of the work is to assess the reliability of the results of geological and geophysical studies of complex-constructed Neogene deposits by electrical methods and to develop optimally reliable approaches to the selection of hydrocarbon-saturated rocks with an assessment of their reservoir parameters. In addition, to establish the factors that affect the ambiguity of geological and geophysical conclusions in the process of research of complex lithological and stratigraphic strata, which ultimately causes the omission of reservoir rocks saturated with hydrocarbons. The obtained experimental results of the research of the core material taken from the wells of the adjacent gas condensate fields made it possible to identify the main factors and parameters that determine the filtration-capacity parameters of Neogene deposits. Based on the above, there is a need to substantiate and develop methodological aspects of the use of electrical methods to determine the nature of reservoir rock saturation and to determine the dynamics of water-gas-condensate contacts. The subject of research is the electrical parameters of water- and gas-saturated reservoir rocks. In addition, the substantiation of the effect of pressure and temperature on the performance of electrical methods in the process of researching complex-constructed Neogene reservoir rocks and the peculiarities of the dynamics of changes in water-oil and gas-water contacts. The decrease in oil and gas production from complex geological sections is due to both economic and technological factors that arise in the process of researching the lithological and stratigraphic strata of the Bilche-Volytsa zone. The geological structure of the above-mentioned territories is extremely complex and represents, in particular in the Bilche-Volitsa zone, a classically expressed wing of the platform type, weakly dislocated by upper Miocene molasses.
