Tectonostratigraphic controls on pore fluid pressure distribution across the Taranaki Basin, New Zealand
Authors: O'Neill Sean R. , Jones Stuart J. , Kamp Peter J. J.
Published: January 2023

Significant variations in pore pressure across the Taranaki Basin, New Zealand, are attributed to changes in lithofacies and structure, usefully illustrated in terms of ten areas that we term geopressure provinces, each displaying individual pore pressure trends. Cretaceous to Early Miocene formations in different parts of the basin can be either normally pressured (near or at hydrostatic) or significantly overpressured (up to 28 MPa) at the same depth. Variations in Eocene–Oligocene facies types and thicknesses both within and between geopressure provinces provide first‐order control on the magnitude, distribution and maintenance of overpressure across the basin. Examples of hydraulic compartmentalisation due to sealing faults and stratigraphic architecture are identified within the basin. Deep pore pressure transitions are sealed by diagenetic, structural or stratigraphic mechanisms in different places and are associated with an increase in mudrock volume (reduced permeability) or gas generation. Thus, pore pressure distribution in the Taranaki Basin is controlled by a combination of sediment loading, lithofacies variations, fault zone permeability and structural architecture. This work represents an appraisal of the pore pressure distribution across the whole of a multiphase structurally complex basin, and the approach taken provides a framework for better understanding the distribution of pore fluid pressures and pore fluid migration in other sedimentary basins.

Published: January 2023

Oral lichen planus (OLP) confers an approximately 1% risk of transformation to oral squamous cell carcinoma (OSCC). Early identification of high‐risk OLP would be very helpful for optimal patient management. We aimed to discover specific tissue‐based protein biomarkers in patients with OLP who developed OSCC compared to those who did not. We used laser capture microdissection– and nanoLC–tandem mass spectrometry to assess protein expression in fixed lesional mucosal specimens in patients with indolent OLP (no OSCC after at least 5‐year follow‐up, n = 6), transforming OLP (non‐dysplastic epithelium with lichenoid inflammation marginal to OSCC, n = 6) or normal oral mucosa (NOM, n = 5). Transforming OLP protein profile was enriched for actin cytoskeleton, mitochondrial dysfunction and oxidative phosphorylation pathways. CA1, TNNT3, SYNM and MB were overexpressed, and FBLN1 was underexpressed in transforming OLP compared with indolent OLP. Integrin signalling and antigen presentation pathways were enriched in both indolent and transforming OLP compared with NOM. This proteomic study provides potential biomarkers, such as CA1 overexpression, for higher‐risk OLP. While further validation studies are needed, we propose that epithelial–mesenchymal transition may be involved in OLP carcinogenesis.

Authors: Du Guanhuan , Deng Yiwen , Pan Lei , Han Xiaozhe , Tang Guoyao , Yu Shiyan
Published: January 2023

Objective

To characterize the bacterial community from different oral niches (buccal mucosa and saliva) in oral lichen planus (OLP) patients.

Subjects and Methods

This preliminary study analyzed site‐specific (mucosa and saliva) microbial landscape of 20 OLP patients and 10 healthy controls.

Results

The microbial diversity was similar between OLP patients and healthy controls in both salivary and mucosal communities. However, the topological properties of co‐occurrence networks of salivary and mucosal microbiome were different between healthy controls and OLP patients. SparCC analysis inferred three and five keystone taxa in the salivary and mucosal microbial networks of healthy controls, respectively. However, in the salivary and mucosal bacterial networks of OLP patients, only one hub OTU and three OTUs were identified as keystone taxa, respectively. In addition, analysis of community cohesion revealed that mucosal microbial community in OLP patients had lower stability than that in healthy controls. In final, correlation assay showed that the clinical severity of OLP was positively associated with the relative abundance of Rothia in saliva but negatively associated with that of Porphyromonas on mucosa.

Conclusions

The salivary and mucosal bacterial communities of OLP patients differ in terms of composition, the genera associated with OLP severity, and co‐occurrence patterns.

Published: January 2023

Background. Patients with unilateral breast cancer carrying pathogenic variants in BRCA1/2 have the option to undergo contralateral prophylactic mastectomy (CPM). However, differences in CPM use and survival outcomes following CPM are poorly understood in this high-risk population, in part due to a lack of data from contemporary clinical cohorts. The objective of this study was to evaluate post-CPM overall survival (OS) and related racial/ethnic differences in a contemporary clinical cohort. Methods. We retrospectively reviewed the medical records of women with a personal history of unilateral breast cancer carrying pathogenic variants in BRCA1/2 who were diagnosed between 1996 and 2012. Genetic test results, self-reported demographic characteristics, and clinical factors were abstracted from electronic medical records. Results. Of 144 BRCA-positive patients, the majority were White (79.2%, n = 114). Overall, 56.1% (n = 81) of all BRCA1/2 carriers chose to undergo CPM, with no racial/ethnic difference in CPM election (

p

 = 0.78). Of 81 patients who underwent CPM, there is strong evidence of a difference in survival between the racial/ethnic groups, with White patients having the highest OS compared to non-White patients (

p

 = 0.001). Of the 63 patients who did not undergo CPM, there is no racial/ethnic difference in overall survival (

p

 = 0.61). In multivariable cox regression, adjusted for demographic and clinical characteristics, OS was significantly lower among non-Whites than in Whites (HR = 0.39,

p

 = 0.04). Conclusions. Evaluation of a contemporary clinical cohort of BRCA-positive women with unilateral breast cancer showed no racial/ethnic difference in CPM use, but there was a significant difference in post-CPM overall survival.

Published: January 2023

Background. COVID-19 has turned into a global public health crisis. This study intended to compare demographic characteristics, disease severity, treatment methods, and clinical outcomes in hospitalized patients with COVID-19 during the third and fourth waves of the pandemic in Golestan Province, Iran. Methods. In this cross-sectional study, the clinical epidemiology of all COVID-19 patients, who were hospitalized in two educational hospitals in Golestan Province for 30 days from the start of the third and fourth waves of the coronavirus pandemic in 2021-2022, was assessed. Their electronic medical records were used to collect their epidemiological, demographic, laboratory, and clinical information and treatment outcome. Results. In all, 930 electronic medical records of the hospitalized patients (351 in the third wave and 579 in the fourth wave) were studied. In the third and fourth waves, 29.06% and 13.13% of the patients had severe COVID-19, respectively (

P

 = 0.001). The number of deaths in the third wave was larger compared to the fourth wave (

P

 = 0.015). The mean duration of hospitalization was longer in the third wave than in the fourth wave (

P

 = 0.001). The drugs administered most in these two waves were remdesivir, dexamethasone, and heparin, and the patients who received these drugs were compared in the third and fourth waves (

P

 = 0.001). Conclusion. The reduced rate of mortality in the fourth wave was compared to the third wave. This reduction can be attributed to the change in the national strategy adopted in terms of hospitalization criteria and treatment protocols taking into account the acquired experience, earlier hospitalization, and start of drug therapy.

Authors: Patterson Gentile Carlyn , Aguirre Geoffrey K , Hershey Andrew D , Szperka Christina L
Published: January 2023

Objective

To compare clinical features in youth with continuous headache from migraine, persistent post-traumatic headache, and new daily persistent headache to determine if they are similar, contrary to their distinction in the International Classification of Headache Disorders.

Methods

We pursued a single center age- and sex-matched observational study comparing the clinical characteristics of 150 youth (11 – 17 years old) with continuous headache from migraine, persistent post-traumatic headache, and new daily persistent headache. A diagnostic algorithm based on international classification of headache disorders criteria was used to identify those with migraine (headache features of migraine with gradual onset), and persistent post-traumatic headache and new daily persistent headache (based on the circumstances of headache onset regardless of headache features). Fifty participants each with migraine, persistent post-traumatic headache, and new daily persistent headache were matched by age and sex. Participant survey responses on headache characteristics were compared.

Results

Median usual headache severity was 6.0 [95%CI 6.0, 6.0] and was not different across diagnostic groups (H statistic = 1.2, p = 0.55). Headache exacerbation frequency, disability, associated symptoms, and most triggers were not significantly different across groups. The majority of persistent post-traumatic headache and new daily persistent headache had headache features consistent with a diagnose of migraine (72% and 62%, respectively).

Conclusion

Our findings suggest that most persistent post-traumatic headache and new daily persistent headache may represent abrupt onset of migraine.
Recent Advances and Technologies in Chitinase Production Under Solid-State Fermentation
Authors: K. Paul Mini , B.T Umesh , Mathew Jyothis
Published: January 2023

ABSTRACT: Our target is to evaluate recent literature on chitinase production from different sources via solid-state fermentation and to analyze several strategies to improve chitinase production via solid-state fermentation. Plant pathogen biocontrol, sequential transformation of chitin into bioactive molecules such as chito-oligosaccharides and N-acetylglucosamine, protoplast synthesis from filamentous fungi, and single-cell protein production are some of the applications for chitinase. Despite their enormous biological importance, chitinases have received little commercial importance due to the smaller percentage of microbes with high efficiencies, the enzymes' decreased activity and consistency, and the cost of production. Solid-state fermentation (SSF) is less expensive, requires fewer vessels, uses less water, requires fewer wastewater treatments, produces a greater product yield, has a lower risk of bacterial contamination, and requires less energy expenditure. Despite its higher productivity and lower cost, the SSF technique is now mostly limited to lab scales. Furthermore, the crude SSF products can be used as an enzyme source for biotransformation. There are many findings on different microorganisms that produce chitinase by SSF. So it is very critical to isolate new organisms for such production. So we assessed the traditional approach to medium optimization, which focuses on changing one factor at a time while leaving the others constant, and statistical optimization techniques such as response surface methodology (RSM), artificial neural networks (ANNs), and genetic algorithms (GA).

Published: January 2023

Judima is traditionally prepared by the Dimasa community of Assam. This is a rice beer traditionally being used by them generation after generation on various occasions and day-to-day life. As Judima got the Geographical Indication tag commercialization of this beverage increased. Therefore, scientific documentation of its method of preparation and characterization is of utmost need of the hour to maintain quality. The two steps involved in the making of Judima are-making of rice cake and the making of rice beer is involved. The state of Judima is liquid and its colour is yellowish. The pH of both fresh and preserved Judima is near 5. The alcohol percentage of fresh Judima is 20±2 mg/ml and Old Judima is 21.5±2 mg/ml, similarly, the Carbohydrate content of fresh and old Judima is 18±1.8 mg/ml and 19.6±2.7 mg/ml respectively. On the other hand, the protein content and free amino acid of fresh Judima are 3.8±1.8 mg/ml and 0.8±0.5 mg/ml respectively and that of Old Preserved Judima is 3.1±0.98 mg/ml and 1.3±0.77 mg/ml. Although indigenous people prefer old preserved Judima for consumption as they have more belended flavours ans smoother to drink it cannot be clearly stated that it is because of the difference in biochemical parameters as the p-value for all the observations is greater than 0.05 therefore, the difference is not significant.

Authors: Huang Jinbao , Wu Yun , Su Bo , Liu Jingping
Published: January 2023

In this paper, we prepare and test a graphene field-effect transistor with two top gates. The Fermi energy level of graphene can be adjusted by applying positive and negative voltages to the two top gates, and N-type and P-type graphene are formed in the channel region, thus inducing a graphene p-n junction. The current model is established using the gradual channel approximation (GCA) method, and the current and p-n junction characteristics of the device were obtained by formula simulations. Based on the principle of p-n junction luminescence, this device with graphene p-n junction is expected to achieve terahertz wave radiation with an appropriate optical resonant cavity.

Published: January 2023

A novel parallelization of discontinuous Galerkin time-domain (DGTD) method hybrid with the local time step (LTS) method on Sunway supercomputers for electromagnetic simulation is proposed. The proposed method includes a minimum number of roundtrip (MNR) strategy for processor-level parallelism and a double buffer strategy based on the remote memory access (RMA) of the Sunway processor. The MNR strategy optimizes the communication topology between nodes by recursively establishing the minimum spanning tree and the double buffer strategy is designed to make communication overlapped computation when RMA transmission. Combining the two methods, the proposed method achieves an unprecedented massively parallelism of the DGTD method. Several examples of radiation and scattering are used as cases to study the accuracy and validity of the proposed method. The numerical results show that the proposed method can effectively support 16,000 nodes (1,040,000 cores) parallelism on the Sunway supercomputer, which enables the DGTD method to solve the transient electromagnetic field in a very short time.

Published: January 2023

Objetivo: Esse estudo tem como objetivo investigar se as mulheres no cargo de gestão diminuem a probabilidade de problemas financeiros.

Método: A amostra da empresa compreende empresas Brasileiras listadas na B3, no período de 2010 a 2018. Utilizou-se o modelo de previsão de problemas financeiros de Altman (1979), e dessa forma regrediu-se as variáveis de interesse relacionados a diversidade de gênero em posições de alta gestão via o modelo econométrico logit. Para garantir resultados robustos, usou-se uma técnica recente para balancear empresas que tinham mulheres na alta gestão com seus pares via PSM e entropia.

Resultados: Os resultados sugerem que quando a mulher está como CEO, as empresas têm maior probabilidade de terem problemas financeiros. No entanto, encontramos que essas empresas já estavam com problemas financeiros antes da entrada da mulher como CEO. Em análise adicional, evidenciamos que a mulher evita problemas financeiros apenas quando a mulher assume a presidência do conselho de empresa dois anos antes da empresa apresentar problemas financeiros.

Contribuições: Entender melhor como a diversidade de gênero pode contribuir para a administração de empresas brasileiras, em sua maioria familiares ou com alta concentração acionário, em situações de crise e dificuldades financeiras, haja vista as recorrentes crises políticas que impactaram a economia Brasileira nesta última década.

Published: January 2023

This study aimed to evaluate the type of floor in the composting process of leaf wastes. The waste consisted of cacao leaves (Theobroma cacao L.), rubberwood leaves (Hevea brasiliensis), teak leaves (Tectona grandis L.f), matoa or Fijian longan leaves (Pometia pinnata), durian leaves (Durio zibethinus), and grass. The research was conducted by composting the leaf mixtures in a composting box sizing 220 cm in length, 180 cm in width, and 100 cm in height. A long box was partitioned by using plastic tarpaulin into four boxes for different floors, namely cement, soil, tarpaulin, and rice husks. A mixture of leaves of 127 kg to 176 kg was introduced in each box and was composted for 145 days. Variables observed were temperature, the height of heap, the mass of material (initial and final), C/N ratio, NPK contents, compost color, odor, pH, and moisture content. The results showed that compost quality fulfilled Indonesian National Standard (SNI 19-7030-2004) regardless of the floor types. However, the type of floors affected the compost process and yield. The composting process with tarpaulin-layered or husk-layered floors produced better compost in terms of N, P, C/N ratio, and color as compared to those resulting from cemented or barely soil floors.
Land subsidence assessment on karst based on resistivity and geotechnical parameters
Authors: Massinai Muhammad Altin , Massinai Muhammad Fawzy Ismullah , Syamsuddin Erfan
Published: January 2023

Karst is geomorphologically composed of limestone. However, limestone is very susceptible to weathering due to the influence of water, which can cause land subsidence. The resistivity method is often used to determine the potential for land subsidence, while geotechnical methods are commonly considered capable of juxtaposing with resistivity methods to support interpretation accuracy. The current research was conducted to determine the potential for land subsidence in the karst area in Lappae, South Sulawesi, Indonesia. The resistivity method utilizes a dipole-dipole configuration, and the geotechnical parameters used are uniformity coefficient, curvature coefficient, water content, shear angle, and cohesion. The results obtained can be classified into northern and southern areas. The classification of these areas is based on the resistivity results, which show very high resistivity values        (> 4800 Ωm) in the southern part. This value is assumed to be a feature of the cave. Caves are predominantly distributed in the southern part. The five geotechnical parameters show that the northern part, which was composed of massive limestone (150-1600 Ωm), is a stable area, though it is highly prone to landslides. As for the southern part, geotechnical parameters suggest that the presence of caves is the primary factor contributing to the very high potential for landslides in this region. These results indicate that, based on the evaluation of this location, it is not feasible for land use. In addition, in spite of the low cost and rapid methods, the combination of these methods shows good results.

Published: January 2023

Like other natural resources, groundwater is also being exploited at an increasing rate, especially for domestic requirements. Groundwater is preferred as a domestic water source because of its continuous availability and relatively good quality. Unfortunately, not all places have sufficient groundwater availability of good quality. The purpose of this study was to analyze the characteristics of the aquifer in the study area and evaluate its groundwater potential for domestic needs. Aquifer characteristics were determined based on geological and geomorphological conditions, while groundwater potential was calculated using a static approach. The results showed that the characteristics of the aquifers in Kediri Regency are various. In the eastern and central parts of the study area, the characteristics of the aquifer can be in the form of unconfined aquifers with high productivity. In the western part, most of them have non-aquifer material, so it is difficult to find groundwater. Groundwater generally fills joints and diaclase formed in andesitic lava with low discharge. Although the conditions of the aquifer are various, in general, the potential for groundwater in Kediri Regency can still support its requirements because the potential for groundwater in Kediri Regency is 71,121,313,394 m3, while domestic requirements is 52,348,490 m3/year.

The electrokinetic remediation method can function as a primary or secondary technology and can be applied in conjunction with other physical and biological methods, such as soil washing, phytoremediation, and bioremediation. Environmental impacts arising from the electrokinetic remediation process can be determined using life cycle assessment analysis (LCA) or other tools. This study compared the conventional electrokinetic remediation strategy with two hybrid strategies: electrokinetic-phytoremediation (EKR-Phyto) and electrokinetic-bioremediation (EKR-Bio). The environmental performance of the three strategies is then tested through LCA analysis. The database used was The Ecoinvent, and the freeware software used during the inventory stage was OpenLCA. The impact assessment stage was used in the Recipe I (2016) midpoints, Available Water Remaining (AWARE) midpoint, Intergovernmental Panel Climate Change (IPCC) midpoint (2003), UNEP Society of Environmental Toxicology (USEtox) midpoint, and cumulative energy demand midpoint. The significance of the analysis results was not obtained for the GWP parameter but for the freshwater eutrophication parameter. Among the three strategies, the EKR-Phyto strategy showed the highest significance in eutrophication but the lowest significance in land change. Substitution of chemical fertilizers into natural fertilizers in the EKR-Phyto strategy can be an opportunity for environmental sustainability. The highest impact for ecological analysis of the three strategies was EKR-Phyto in terms of GWP, the sum of primary energy, Acidification Potential (AP), and Photochemical Ozone Creation Potential (POCP).

Authors: Nafikov Ravil Z , Kislyakov Victor E , Kirsanov Aleksandr K , Teshaev Umarjon R
Published: January 2023

The volumes of world gold mining were reviewed. As a result of the analysis, it was found that the proportion of placer gold is very insignificant. This is due to the fact that the most easily accessible reserves are substantially depleted, and the development of deposits with complex mining and geological conditions, including those located in the Far North, is economically impractical. To solve this problem, a method was proposed for isolating the dredging open-pit from the effects of negative temperatures by a hangar-type structure. Similar structures used in the mining industry were considered. Calculations of the dimensions of the structure that allow for safe manoeuvring of the dredge were presented. The data on the duration of the dredging season when implementing the proposed solution in the conditions of the Far North were provided. A method of protecting rocks from freezing when using this technology was proposed. The technical and economic indicators confirming the effectiveness of the implementation of the proposed solution were presented.

Humic acids play a crucial role in ion exchange and metal ion complexes; therefore, they are potentially useful in improving soil fertility and crop yield. This study aimed to explore the role of humic acid (HA) from various composts in improving degraded soil fertility and maize yield. A field experiment was conducted on Inceptisols having low soil organic carbon, nitrogen and available phosphorus contents. Eight treatments of HA formulas and one control were arranged in a randomized block design with three replications. The HA formulas used were combinations of two doses of HA (0.15 and 0.20% of soil on w w-1 base) and four types of HA (HA extracted from bagasse compost, HA extracted from water hyacinth compost, HA extracted from market waste compost, and commercial HA). The results showed that the HA application increased 16-97% of soil organic carbon, total nitrogen, available phosphorus, exchangeable potassium and calcium compared to the control. The formula of commercial HA at 0.15% was the best treatment for inhibiting soil fertility degradation in agricultural land. The best maize yield of 15.13 t ha-1 and starch content of 63.54% was obtained from the application of commercial HA at 0.20%.

Agricultural soil is possibly threatened by lead (Pb) contamination due to the intensive use of fertilizers. The rhizobacteria were recommended for the bioremediation of soils contaminated by low concentrations of Pb. The experiment was conducted to observe the Azotobacter's ability to proliferate in Pb-contaminated broth and to decrease the Pb availability in soil, Pb uptake by sweet potato roots, and sweet potato growth. The resistance test was performed by growing five Azotobacter isolates in N-free broth with various Pb levels. A pot experiment was conducted in a factorial randomized block design to test three levels of Pb in soil and two Azotobacter isolates. The results showed that Azotobacter Azv4 and A. choroococcum were resistant to 100 mg L-1 Pb in N-free broth. In the pot experiment, Azotobacter Azv4 Inoculation caused less Pb in soil and roots of sweet potatoes grown in Pb-contaminated soil than A. choroococcum. Either Azotobacter or Pb soil did not influence vine length. However, Azv4 was more prominent in increasing branch number, root volume and length; higher Pb in soil reduced branch number but did not affect root parameters. Azotobacter Azv4 increased more shoot and root dry weight compared to A. choroococcum, but both isolates did not change the shoot-to-root ratio (S/R). The Pb contamination only reduced root dry weight and reduced the S/R. This research considered utilizing rhizobacteria Azotobacter for reducing Pb levels in soil and roots; and increasing sweet potato biomass.
The Relationship Between BOD Ethical Commitment and Risk Management and Internal Control System with the Performance of Shariah-Compliant Companies

Published: January 2023

Shariah companies need to maintain good performance to ensure the sustainability of companies. Shariah companies operate based on Islamic moral foundations, specifically in terms of their accountability and transparency which are considered as key values that need to be considered when conducting their business operations. However, corruption cases can affect the performance of Shariah companies. Studies have shown that Shariah-compliant companies are underperforming as compared to their conventional counterparts. Therefore, the objective of this study is to examine whether BOD ethical commitment (corporate ethics values, action to promote ethics, code of ethics and whistleblowing policy) and risk management and internal control system (content, implementation, role, objective, framework and separation section) will affect the performance of Shariah companies. Data was collected from the 2019 annual reports of 60 Shariah manufacturing companies. Data was analysed using Smart Partial Least Square. The study found BOD Ethical Commitment (whistleblowing policy) and Risk Management and Internal Control System (separation of risk management and internal control) have a significant relationship with performance. The study implies that shariah-compliant companies should focus on the disclosure of whistleblowing policy and separation of risk management and internal control system in their annual reports for them to improve their performance as disclosure of this information, will help to improve the confidence of the market to invest in them
Application of Bibliotherapy in Gestalt Therapy: Fiction Books as a Stimulant of Personality Transformation
Authors: Girčienė Jurgita , Žukauskienė Daiva
Published: January 2023

The theory of the Gestalt therapy which is based on the humanist attitude towards the personality is applied in the social work, education, etc. It is considered to serve as a foundation of interactive bibliotherapy. However, as the professional discourse of the experts of Gestalt has demonstrated, and as it has been proven by the lack of research of the application of bibliotherapy in Gestalt therapy, bibliotherapy is still being underused as an option in Gestalt treatment. Generally, even though the interdisciplinary field of bibliotherapy has been extensively explored, there is an incentive to share the scarce (in terms of quantity) models of the applied nature which would define how bibliotherapy could be systematically involved into various consultation practices with the objective to enhance their efficiency. The article presents one of the possible models of practical application of interactive bibliotherapy in the Gestalt practice which is based on the triple dialogue (in interaction with the therapist) and written reflection of brief fictional texts. The model is based on the grounds of aligning the paradigms of Gestalt therapy and bibliotherapy. Cases of 60 clients who were being applied bibliotherapy throughout the 7 years of operation of one practice were explored with the emphasis on the qualitative aspect. The results of the research proved the appropriateness of bibliotherapy as a secondary means to be applied in Gestalt therapy. It has been established that, under the appropriate field conditions, the properly selected fictional text as the mediator through the dialogue-based reflection with the therapist may help the client to perceive his/her unsatisfied needs and to alter in the desired direction within a shorter timeframe, i.e., it enables personality transformation. In such cases, works of fiction serve the function of the stimulants of the authentic intrapersonal communication (i.e., one’s inner experiences and their inner reflection) and the amplifying or reinforcing function of the stimulants of interpersonal communication. This corroborates the data of neurological research indicating that fiction intensively stimulates and even (trans)forms the intellectual and emotional self- and world perception of a reading individual. The presented model of the application of bibliotherapy may be beneficial not only for the practitioners of Gestalt, but also for librarians, social workers and education specialists as well as the practitioners of therapies of other types, while especially considering the lack of systematic descriptions of the application of bibliotherapy as an additional and enhancing means, which has been highlighted in the relevant literature.
Documentary Heritage of 1773–1923 of Siberian Archives with Significance to Lithuania
Authors: Bilotas Viktor
Published: January 2023

Extensive archival documentation related to Lithuania and Lithuanians is kept in Russia, and not only in St. Petersburg or Moscow. Archival cases of Lithuanians containing high numbers of ego-documents, are dispersed throughout the vast territory, and are especially numerous in the Siberian memory institutions. Thanks to the project Lithuanian Sibiriada, copies of documents brought from Tobolsk, Tomsk, Krasnoyarsk and Irkutsk can be found in the Lithuanian State Historical Archives. By using the analysis of documents and the method of classification, this article tries to systematize the information about the relevant materials found in the state archives of Siberia and to determine their typology.
The studied documentation covering the period between 1773 and 1923 was found to belong to such areas of public life as politics, economics, science, education, culture, religion, administration, law, statistics, labor, and migration. These are documents (ranging from drafts and copies to official originals) produced by Lithuanians themselves, scribes, state officials not only in Siberia, but also in Lithuania, St. Petersburg or other parts of the Russian Empire. By type, among the discovered documents, there are decrees and manifests, deportation sentences, appointment letters, certificates, sheets, decisions, court records, lists, metrics, reports, reviews, statistics, financial documents. In terms of ego-documents, letters, requests, complaints, explanations, and wills can be found. With such texts, people sought to report, ask, defend themselves or those close to them, or bequeath property. The government created documents with the purpose of informing, registering, taxing, deporting, liberating, accommodating, employing, accumulating data; (not) issuing permits, allowances, salaries. Photos were taken for the mass media, identification, or inspection.
Siberian documents touch on such topics as the uprisings, the annexation of the Grand Duchy of Lithuania, attempts of Russification, exiles and prisoners, police surveillance, deaths, liberation, return to the social group, employment, marriage, obtaining a passport, business, resettlement, return to Lithuania. Documentary testimonies are available about free Lithuanians in Siberia: workers and farmers, students and teachers, businesspeople and craftsmen, doctors and priests, officials and various specialists, war refugees and repatriates. The addressees of the letters were the governors’ offices, directorates, courts, various institutions, officials, private people.
The study showed that, between 1773 and 1923, Siberian documents about Lithuanians most frequently concern the deported persons (political, criminal), their data and applications. Yet, there are also archival cases significant for the history of Lithuania about the Lithuanian colonies, various specialists, famous personalities, businesspeople, about events in Lithuania itself.

Objectives: The aim of this study was to investigate factors predicting spontaneous stone passage after Flexible Ureteroscopic Lithotripsy (fURS) for renal stones. Materials and Methods: This study included 239 patients with renal stones who underwent fURS using the dusting technique. The final outcome was evaluated 3 months postoperatively and the Residual Fragment status (RFs) was defined as any residual stone fragments greater than 2 mm. Univariate and multivariate analyses of possible predictive factors associated with spontaneous clearance of residual renal fragments were performed. Results:186 patients (77.8%) had achieved an Stone-Free status (SFs) and 53 patients (22.2%) were considered with RFs. Univariate analysis showed the stone location, stone number, stone size, stone CT value, IPA degree, the presence of hydronephrosis and stone covered with purulent substance were all associated with RFs (P<0.05). Multivariate logistic regression analysis showed that larger stone size (P=0.001), multiple stones (P=0.038), the IPA of <45° (P=0.035), the presence of hydronephrosis (P=0.045), the stone CT value ≥ 1000 (P=0.047) were all significantly associated with higher rates of residual stone after fURS. The stone covered with purulent substance was found to be the strongest predictor of RFs (P=0.027). However, the presence of lower pole stone had no significant influence on stone clearance after fURS (P=0.263). Conclusions: Stone number, stone size , an IPA of <45°, stone CT value ≥ 1000 HU, stone covered with purulent substance and presence of hydronephrosis are all predictive factors of the spontaneous clearance of residual renal fragments after fURS.
Caracterización del potencial térmico RSU, para la generación de energía eléctrica, utilizando carbonización hidrotérmica
Authors: Salazar Anibal
Published: January 2023

El cenit del petróleo y el efecto invernadero son las razones que justifican la necesidad de utilizar energías renovables no convencionales (ERNC). Los residuos sólidos urbanos constituyen una de esas fuentes, por lo que la determinación de las principales características, incluido el poder calorífico, fue el primer objetivo de la presente investigación, así como la utilización de los modernos procedimientos de carbonización hidrotermal (CHT) y licuefacción hidrotermal (LHT), para la generación de energía y potencia eléctrica. Se trabajó con los datos de muestreo de los residuos sólidos urbanos del área de Chiclayo metropolitano. Se empleó una bomba calorimétrica para la medición del poder calorífico y la simulación numérica del potencial de generación eléctrica. Además, se obtuvo como resultado el cumplimiento del objetivo principal, y el hecho de que es posible obtener energía y potencia firme, que ayude a evitar las emisiones de gases efecto invernadero, contribuyendo a los compromisos firmados con tal efecto y a seguir el camino a una nueva matriz energética sostenible; a la vez se da una posible solución al problema del manejo de residuos sólidos urbanos, principal problema ambiental de la ciudad de Chiclayo, Perú.
STS Between Centers and Peripheries: How Transnational are Leading STS Journals?

Published: January 2023

In the context of increasing internationalization of the science and technology studies (STS) field, and reflections on post-coloniality and provincialization of STS, we examine to what extent a set of twelve leading journals of the field have published papers from different regions worldwide. In this exploratory work, based on information retrieved from the Web of Science for the period 2010–2019, we often use Latin America as an example, but reflect on peripheral regions of the field more broadly. Our findings show that the historical West-European–North-American centers of the field maintain their hegemony, dominating the discussions in leading journals. Some Latin American and East Asian countries gained some visibility in journals focused on scientometrics and science and technology (S&T) policy and innovation, whereas the journals specialized in the socio-anthropological studies of S&T are the less transnationalized. Our preliminary hypothesis to explain such sub-field variations is that these objects (scientific policy, innovation) and methods (scientometrics) seem to be more universal and consensual, facilitating transnationalization, while peripheral science, the preferred object of study for peripheral STS, has not attracted attention from leading journals. Emphasizing the relational character of centers and peripheries, we argue that the invisibilization of the academic production of certain regions of the world in leading journals makes this work peripheral.
