O rio Paraim, localizado no município de Corrente no sul do Estado do Piauí (PI), é tido como essencial para atividades das comunidades ribeirinhas e para as cidades de Corrente e Sebastião Barros. Contudo, este rio tem apresentado graves problemas de degradação, poluição e assoreamento em suas margens, e consequentemente perdas no volume de vazão, sobretudo nos períodos de estiagem. Uma forma de revitalização dos rios é a recuperação de nascentes degradadas, sendo a caracterização das nascentes uma alternativa viável e eficiente. Com isso, objetivou-se caracterizar o grau de preservação de uma das nascentes do rio Paraim e de sua mata ciliar, localizada no município de Corrente. O estudo foi realizado na área da nascente do Brejo da Prata, cujo bioma é o Cerrado. A caracterização macroscópica da nascente foi feita em consonância com 20 parâmetros, sendo quantificado o nível do impacto para cada um dos parâmetros avaliados. Após a avaliação e quantificação dos parâmetros utilizados, foi realizado o somatório dos pontos atribuídos aos parâmetros, e em seguida estimou-se o grau de preservação da nascente. Foram identificados vários parâmetros com algum grau de degradação, sendo os de maiores destaques a desconformidade da mata ciliarcom a legislação vigente, o acesso antrópico e de animais, a presença de resíduos sólidos e o carreamento de solo para o interior da nascente. A classificação do grau de preservação da nascente analisada por este estudo (moderadamente preservada) deixa evidente que as atividades antrópicas e agrícolas estão promovendo sua degradação. Projetos científicos, como levantamentos fitossociológicos e plantios de mudas, também deveriam ser executados na região de localização da nascente do Brejo da Prata para que a área de preservação permanente seja recuperada.

Abstract
The development of sandstone-type geothermal energy is an important part of the development of geothermal resources and has great significance in promoting environmental protection and energy structural transformation. In sandstone geothermal energy development, recharging is the main method to ensure bottom hole pressure. However, the pressure and temperature changes of sandstone reservoirs under recharge conditions have not been extensively studied. It is easy to ignore the hydraulic relationship between the production and the injection wells, which leads to an increased risk of thermal breakthrough. Therefore, a three-dimensional hydrothermal coupling model is established, and simulation studies of different flow rates, well lengths, and well spacings are completed in this paper. Here, we show the numerical simulation results. The low temperature expansion zone and hydrostatic pressure near the injection well increase with increasing flow rate, and the maximum expansion of the low temperature zone is about 350 m. The low temperature expansion area near the injection well has a small relationship with the well spacing, and the increase in hydrostatic pressure is proportional to the well spacing. As the length of the well increases, the increase in hydrostatic pressure near the injection well decreases, indicating that the injected water under the long well section easily enters the reservoir. When no thermal breakthrough occurs and the hydrostatic pressure drops significantly near the production well, it is recommended that the flow rate be controlled at approximately 20–25 L/s, the well spacing should be 600–800 m, and the well length should be greater than 100 m.
Improving the Efficiency of Managing the Development of the West Siberian Oil and Gas Province Fields on the Basis of Differentiation and Grouping
Authors: Mukhametshin V.V. 
Published: December 2021

Abstract
—Using image recognition methods (principal component method (PCM) and discriminant analysis) made it possible to group and identify more than 500 research objects developed in five oil and gas areas of the West Siberian oil and gas province (WSOGP), which are confined to 13 large tectonic structures and 10 productive horizons. The grouping was made according to 19 parameters characterizing the mode of oil and gas occurrence and the geologic–physical and physicochemical properties of the reservoirs and hosted fluids exerting a prevailing influence on the recovery of oil reserves and used on projecting the development of research objects. The performed study has identified 19 relatively homogeneous groups of objects, each having a specific set of geologic–physical properties. It is shown that the parameters reflecting the geologic–physical and physicochemical properties of the reservoirs and fluids within the identified groups of objects exert different effects on the recovery of oil reserves. This requires differentiation and grouping of the objects during the solution of various development problems. It has been established that the specific features of groups of objects are determined primarily by areal, tectonic, and stratigraphic factors and that grouping must be performed separately in each stratigraphic system. Algorithms are proposed for grouping the developed oil and gas fields and for searching for groups of analogous objects in fields out of exploration that are most similar to the developed ones. The performed grouping and the results obtained provide the necessary information about the research objects and increase its reliability, thus making it possible to improve the efficiency of managing the oil company assets, i.e., the WSOGP oil fields.
Immunohistochemical Expression of MDM2 and p16 in Adipocytic Neoplasms Measuring Ten Centimeters or more in Diameter among Filipino Patients in a Public Tertiary Hospital from 2017 to 2019
Authors: Masalunga Marvin , Rivera Jonathan , Carnate Jr. Jose 
Published: December 2021

Introduction: A size of more than 10 cm suggests that a soft tissue tumor might be malignant. Pertinent ancillary diagnostic testing, such as immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), may be done to confirm the diagnosis. Several studies have shown that size may be a useful criterion in determining which tumors are candidates for further molecular testing. MDM2 and p16 are IHC markers for atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDLPS).
Objectives: The primary objective of this study is to determine the proportion of tumors signed out as “lipomas” from 2017 to 2019, and measuring at least 10 cm, that express MDM2 and p16 on IHC and warrant revision as ALT/WDLPS.
Methodology: This is a descriptive, retrospective cohort study in which all lipomas from 2017 to 2019 that measured at least 10 cm were included. The size, age of the patient, and location of each tumor were documented. The slides of all eligible cases were reviewed and immunohistochemically stained for MDM2 and p16. For each case, the intensity and immunoreactivity of each stain were assessed using a modified, four-tier scoring system. Fisher’s exact test was used to determine if a significant number of tumors expressed MDM2 or p16.
Results: Thirty (30) cases satisfied the inclusion and exclusion criteria. The average size of these tumors is 15.10 cm. There is no sex predilection. The most common location of these tumors is the extremities. None of the tumors expressed MDM2, and only one case was p16-positive. The case positive for p16 also showed cytologic atypia and variability in cell size, resulting in the revision of its diagnosis from lipoma to atypical lipomatous tumor. The rate of diagnosis revision after slide review and IHC studies is 3.33%.
Conclusion: None of the adipocytic tumors that measured at least 10 cm in diameter and were signed out as lipomas was MDM2 positive, and only one case was p16-positive. Thus, morphology remains the cornerstone in the diagnosis of adipocytic tumors. Careful microscopic evaluation is necessary to establish the diagnosis of malignancy in these tumors. Ancillary tests should only be considered in cases where the pathologic features are equivocal.

Published: December 2021

Abstract
Purpose: To evaluate the ellipsoid zone (EZ) changes according to the types of diabetic macular edema (DME) on optical coherence tomography (OCT) after intravitreal bevacizumab injection. Methods: In this retrospective study, medical records of the patients who had treatment-naive DME and underwent intravitreal bevacizumab treatment between January 2015 and December 2021 were analyzed. Patients who meet the inclusion criteria and completed the follow-up period of 12 months were divided into 4 groups according to the types of diabetic macular edema on OCT (Diffuse DME [Group-1], cystoid DME [Group-2], diffuse DME with serous retinal detachment (SRD) [Group-3] and cystoid DME with SRD [Group-4]). Primary outcomes were EZ changes between the groups.Results: 125 eyes of 96 patients who fulfilled the inclusion criteria and completed the follow-up period were included in the study. There were no statistically significant differences in EZ improvements between the groups at 4, 6 and 12 months after treatment (p =0,594, p=0,836, p=0,486, p=0,748 respectively). The mean logMAR BCVA and CMT of all eyes showed significant improvement at 4, 6 and 12 months. When the mean CMT was compared between each groups, there were significant differences between the Group-1and Group-4 at 4, 6 and 12 months after treatment. (p<0,05)Conclusion: The BCVA gains and improvement in the CMT were maintained in all four DME types during the first year of intravitreal bevacizumab therapy. The improvement in EZ disruption was not depent on the type of DME and improved similarly in all groups.

Published: December 2021

Abstract
Purpose: To compare the visual and anatomic outcomes of intravitreal ranibizumab versus aflibercept in patients with diabetic macular edema (DME) in a real-world study.Methods: This is a single-center retrospective comparative study of treatment-naïve patients who received intravitreal ranibizumab or aflibercept administration for DME for at least 12 months on an as needed regimen following three-monthly loading doses. The primary outcomes of the study were the mean change in best-corrected visual acuity (BCVA), central macular thickness (CMT), central macular volume (CMV). Factors to potentially affect these parameters were also analyzed.Results: A total of 100 eyes (66 patients) were included in the study. Fifty two eyes received ranibizumab and 48 received aflibercept injections. While the decrease in mean CMT at the 4th-month visit was significantly higher in the aflibercept-treated group than in the ranibizumab-treated group (p=0.02), there was no difference between the two groups at the end of the one-year follow-up (p=0.25). There was no significant difference between the two groups in terms of change in mean CMV during the follow-up. (p=0.26, p=0.27 at 4 and 12 months, respectively). The mean number of injections were also similar between groups (4.5 ± 1 vs. 4.6 ± 1.1 respectively, p=0.63).Conclusion: In a real-world setting, ranibizumab and aflibercept were both found to be effective in the first-line treatment of DME. Patients with DME who received fewer injections in the real-world could achieve visual and anatomical results comparable to randomized controlled trials participants.
Ranking Routes In Semiconductor Wafer Fabs
Authors: Gupta Shreya , Hasenbein John J. , Kim Byeongdong 
Published: December 2021

Abstract
We develop a method to estimate the quality of processing routes in a wafer fabrication process. Ranking such routes can be useful for identifying the “best” and “worst” routes when making adjustments to recipes. Route categorization is also useful in developing efficient scheduling algorithms. In particular, we propose a method for ranking routes based on count-based metrics such as the number of defects on a wafer. We start with a statistical model to produce a “local” ranking of a tool and then build a “global” ranking via a heuristic procedure. Creating a fully statistical procedure for ranking routes in semiconductor fabrication plants is virtually impossible, given the number of possible routes and the limited data available. Nonetheless, our discussions with working engineers indicate that even approximate rankings are useful for making better operational decisions.

Authors: Ali Zaara , Asmatulu Eylem 
Published: December 2021

Abstract
Purpose Carbon fiber, Kevlar® fiber, and glass fiber are the most widely used polymer prepregs in manufacturing high-performance composites to produce vital parts for a wide range of applications. The production of carbon and Kevlar® fibers is an energy-intensive process, requiring 198–595 MJ to produce 1 kg of virgin carbon fiber. However, chemically recycling these expired prepregs takes only 38.4 MJ/kg, which could be significantly sustainable. The work described in this study involves an array of experiments involving acid treatment of outdated prepreg composite fibers to study its effects and reclaim the fibers for future applications.Method The experiments were carried out at two different temperatures: 25°C and also 60°C. Sulfuric acid, nitric acid, acetone, and distilled water were used in the process, with varying treatment times of 60, 120, 240, 360, and 420 seconds. The recovered fibers were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Result The optimum treatment time and temperature were different for all three types of fibers. Initially, the glass fiber yielded promising results at room temperature and with a minimal 120-s processing time. Carbon fiber treatment was successful at 60°C with a 420-s treatment time. However, some surface damage was observed in the Kevlar® fiber at 60°C. Conclusion The chemical recycling process is the most sustainable, energy- and cost-efficient approach compared to all other available recycling processes. Also, it is possible to recover much cleaner fibers with the weave intact with an acid treatment and solvent-based recovery.

Abstract
BackgroundSince 2011 Italy has faced an extraordinary increase in migrants arrivals, mainly from the Mediterranean route, one of the world’s most dangerous journeys. The purpose of the present article is to provide a comprehensive picture of the migrants' health status in the centre "T.Fenoglio", Settimo Torinese (Turin, Italy).MethodsA retrospective cross-sectional study was conducted using data collected from June 2016 to May 2018 on adult migrants (>18 years) from Africa, East and Middle East. Data was collected through the migrants' medical records. Descriptive statistics were performed on socio-demographic variables. The diagnosed diseases were anonymously registered and classified according to the International Classification of Primary Care (ICPC-2).Conditional Inference Trees were used to perform a descriptive analysis of the sample and to detect the covariates with the strongest association with the outcome variables Disease on Arrival and ICPC-2 for diseases on arrival.ResultsAnalyzed observations were 9857. 81.8% were men, median age was 23 (Interquartile range= 20.0-27.4). 70.3% of the sample came from Sub-Saharan Africa. 2365 individuals (24%) arrived at the center with at least one disease. On arrival, skin (27.71%), respiratory (14.46%), digestive (14.73%) and generic diseases (20.88%) were the most frequent. During the stay respiratory diseases were the most common (25.70%). The highest probability of arriving with a disease occurred in 2018 and in the period September-November 2016, in particular for people from the Horn of Africa. During this period and also in the first half of 2017, skin diseases were the most reported. In quarters with lower prevalence of diseases on arrival the most common disease code was generic for both men and women.ConclusionsHorn of Africa was the most troubled area with severe conditions frequently reported regarding skin diseases, in particular scabies. 2018 was the most critical year, especially for migrants from Horn of Africa and Sub-Saharan Africa. A better understanding of the health status of asylum seekers is an important factor to determine a more efficient reception and integration process and the better allocation of economic resources in the context of migrants' health care.

Published: December 2021

Abstract
Lake Ziway is shallow freshwater located in Northern part of Ethiopian Rift Valley. It is characterized as semi-arid to sub-humid type of climate. Expansions of the flower industry, widespread fisheries, intensive agricultural activities, fast population growth lead to deterioration of water quality and depletion of aquatic biota. In this study, spatial and temporal variations of selected water quality parameters of Lake Ziway were evaluated using multivariate statistical techniques in the study periods of 2014 and 2015. Monthly water quality data were collected from nine sampling stations during dry and wet seasonal basis for analysis of 15 water quality parameters. Mean nutrient concentrations showed increasing trend and were higher in Floriculture effluent (Fb) and Floriculture effluent after mixing in the lake (Fa) in all seasons. These sites were also characterized by high electrical conductivity (EC) and total dissolved solid (TDS). All the nine sampling sites were categorized into three pollution levels according to their water quality features using cluster analysis (CA). Accordingly, sampling sites Fb and Ketar River (Kb) are highly and moderately polluted in both seasons, respectively. On the other hand, sampling sites at the center (C), Meki river mouth (Ma), Ketar river mouth (Ka), Meki River (Mb), Korekonch (Ko) and Fa in dry season and Ka, C, Ma, Ko, Bulbula river mouth (B) and Fa during wet season were less polluted. Principal component analysis (PCA) analysis also showed the pollutant sources were mainly from Fb during dry season Mb and Kb during wet season. The values of comprehensive pollution index illustrated the lake is moderately and slightly polluted in dry and wet seasons, respectively. Comparatively, the pollution status of the lake is high around floriculture effluent discharge site and at the two feeding rivers (Kb and Mb) due to increasing trends in agrochemical loads. This may lead to long term ecological changes in the lake unless possible measures taken.
