Study and application of temporary plugging agent for temporary plugging acid fracturing in ultra-deep wells of Penglai gas field
Authors: Wang Yang , Fan Yu , Chen Weihua 
Published: March 2023

The burial depth of Penglai gas field reservoir in the Sichuan Basin of China exceeds 7,000 m, and the reservoir temperature is 160°C. Penglai gas field belongs to the fractured reservoir, and there are many natural fractures distributed in the reservoir. Natural fractures are not only the storage place of natural gas, but also the transportation channel of natural gas. Gas wells mainly increase natural gas production through acid fracturing. In the early stage, Penglai Gas Field mainly used gelled acid fracturing technology to create an artificial fracture in the reservoir by injecting a large amount of acid fluid. However, the stimulation range of gelled acid fracturing is very small. After acid fracturing, gas wells can only produce 120,000 cubic meters of natural gas per day. To obtain higher natural gas production, this paper proposes a multi-stage temporary acid fracturing technology that can greatly improve the effect of acid fracturing. The temporary plugging agent for acid fracturing has been developed to meet the high-temperature requirements of the Penglai gas field. Based on the simulation of fracture propagation, the feasibility of acid fracturing expansion of natural fractures in the Penglai Gas Field is clarified. Fiber and granular temporary plugging agents that meet the plugging strength greater than 20 MPa are selected by using the dynamic temporary plugging instrument. MultiFracS software is used to optimize the multi-stage temporary acid fracturing process parameters. The research results in this paper have been applied to wells PS101, PS102, and PS103. After fracturing, compared with the gelling acid fracturing, the natural gas production has increased by more than three times, and the multi-stage temporary plugging acid fracturing has achieved a very good stimulation effect.

Authors: Lin Yanru , Gao Wei 
Published: March 2023

ObjectiveThis study aimed to evaluate the effect of an exercise intervention on improving and alleviating anxiety symptoms in college students with a meta-analytical approach.MethodsSeveral databases (e.g., PubMed, Embase, and the Cochrane Library) were used to search for randomized controlled trials (in short, RCTs) on interventions for physical exercise or aerobic exercise in college students with anxiety symptoms. Stata software, version 16.0, was applied sequentially for traditional meta-analysis, subgroup analysis, and publication bias analysis.ResultsA total of nine papers were included. The total literature effect [SMD = −0.55, 95% CI = −0.76 to −0.35, Z = 5.38 (P &lt; 0.001)] indicated that physical activity had a significant effect on alleviating anxiety. Subgroup analysis also showed that exercise interventions using aerobic exercise or yoga were effective in relieving anxiety (SMD = −0.39, 95% CI = −0.74 to −0.04; SMD = −0.76, 95% CI = −1.14 to −0.39).ConclusionPhysical activity interventions were shown to have a positive effect on alleviating anxiety in college students. Aerobic exercise was found to be the optimal mode.

Published: March 2023

IntroductionThe Padlet interactive platform constitutes a virtual online board on which users can post various types of multimedia content, such as documents, questions, comments, images, video clips, and audio clips. This platform has gained popularity in higher education yet remains ancillary in the fields of medical education and medical management.MethodsThis case study sought to initially design an intervention program that employs online collaborative learning enabled by Padlet and to assess how Health Management students perceived the activity and its ramifications for their learning. 85 students’ reflective journals were content analyzed.Resultsfive main categories stood out: (1) user experience of the platform; (2) visuality and visibility of the platform; (3) collaborative learning and OCL; (4) active online learning and student engagement; and (5) cognitive flexibility.DiscussionThis study emphasizes the importance of incorporating digital tools in education, particularly the use of the Padlet platform to facilitate collaborative learning and improve the quality of teaching and learning. It demonstrates that Padlet-mediated online collaborative learning can be an effective digital learning tool because of its ease of use and ability to accommodate both pedagogical and technological challenges.

BackgroundCOVID-19 pandemic has led to school closure and social distancing measures for infection control. Many young people thus spent more time on electronic devices and the Internet. This study aimed to determine if and how sexual knowledge, perception and behavior as well as sexuality among Hong Kong adolescents were affected as a result.MethodsYouth Sexuality Study conducted by The Family Planning Association of Hong Kong (FPAHK) evaluated the sexual knowledge, attitudes and behaviors and sexual health of youth every 5 years since 1981 with adaptations made to the changing environment. We analyzed this cross-sectional data on sexual knowledge, attitude, and experiences as well as the impacts of COVID-19 on daily life, health and relationships. Univariate analysis was conducted to investigate the relationships between the time spent on electronic devices and sexuality, while mediation analyses using the PROCESS procedure were performed to further explore differences in time spent on electronic devices.ResultsDuring the COVID-19 pandemic, the majority of our participants spent more time on social media and browsing the Internet on electronic devices with less time for extracurricular activities and learning. Nonetheless, there was better overall sexual knowledge and a lower degree of sexual stigma with a higher overall acceptance of sexual minorities. The mediation analyses found that sexual content [Conditional effect = 0.024 (95% CI 0.008, 0.043)] and engagement online [Conditional effect = 0.036 (CI 0.021, 0.053)] could indirectly influence the effect of screen time on the frequency of sexual practices.ConclusionPolicymakers and frontline professionals should re-examine the pedagogy of the present sex education and consider online sex education as the key mode of delivery while guiding the proper use of electronic devices in the learning and exploration of sexual knowledge.

Published: March 2023

PurposeThe aim of this study was to explore the treatment outcomes of a novel single lateral approach via fibular fracture line for patients with posterior pilon fractures.Patients and methodsFrom January 2020 to December 2021, a total of 41 patients with posterior pilon fractures who received surgical treatment in our hospital were retrospectively reviewed. Twenty patients (Group A) were treated with open reduction and internal fixation (ORIF) via posterolateral approach. Twenty-one patients (Group B) were treated with ORIF using a simple single lateral approach via stretching fibular fracture line. Clinical assessments, including operation time, intraoperative blood loss, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS), and the active range of motion (ROM) of the ankle at the final follow-up visit after surgery, were performed in all patients. Radiographic outcome was evaluated by using the criteria proposed by Burwell and Charnley.ResultsThe mean follow-up time was 21 months (range 12–35). The average operation time and intraoperative blood loss in the Group B were significantly less than those in the Group A. Moreover, the AOFAS score and ankle ROM in the Group B were significantly higher than those in the Group A at the final follow-up visit. Eighteen cases (90%) in Group A and 19 cases (90.5%) in Group B achieved anatomical reduction of the fracture.ConclusionThe single lateral approach via stretching fibular fracture line is a simple and effective technique for reduction and fixation of posterior pilon fractures.

IntroductionWhile prevention is increasingly important in the dairy sector, implementation of cost-effective preventive measures is often lacking. To increase the use of these measures and consequently improve animal welfare and reduce financial losses for farmers, it is necessary to know the drivers and constraints of farmers to engage in prevention.MethodsTherefore, we invited farmers to participate in an online questionnaire, which contained questions about their behavior toward either claw health or calf health. We used the theory form the Stage of Change model, COM-B, as well as the Theory of Planned Behavior to formulate our questions. We used the responses of 226 farmers in our analyses, who were equally distributed over the two groups of diseases.Results and discussionWe found that 63.5% of responding farmers were in the action phase or the maintenance phase to prevent claw diseases and even more (85.4%) to prevent calf diseases. The responses also suggest that many farmers have the knowledge and skills to implement preventive measures for both claw and calf diseases. The scores for social and physical opportunities for calf diseases were significantly higher than for claw diseases and all other COM-B components were also numerically higher for calf diseases. This suggests that farmers' perception of taking preventive measures against claw diseases is more difficult than taking preventive measures against calf disease. The automation of preventive behavior scored relatively low for both groups of diseases, which suggests that farmers may need reminders to persist in their activities and support to create habitual prevention behaviors. From these results, we concluded that creating social norms, supporting discussions among farmers, and using environmental adaptations may result in more preventive behavior.

Objectives: Chronic kidney disease (CKD) implies increased comorbidity burden, disability, and mortality, becoming a significant public health problem worldwide, however, prevalence data are lacking in Hungary.Methods: We determined CKD prevalence, stage distribution, comorbidities using estimated glomerular filtration rate (eGFR), albuminuria, and international disease codes in a cohort of healthcare utilizing residents within the catchment area of the University of Pécs, in the County Baranya, Hungary, between 2011 and 2019 by database analysis. The number of laboratory-confirmed and diagnosis-coded CKD patients were compared.Results: Of the total 296,781 subjects of the region, 31.3% had eGFR tests and 6.4% had albuminuria measurements, of whom we identified 13,596 CKD patients (14.0%) based on laboratory thresholds. Distribution by eGFR was presented (G3a: 70%, G3b: 22%, G4: 6%, G5: 2%). Amongst all CKD patients 70.2% had hypertension, 41.5% diabetes, 20.5% heart failure, 9.4% myocardial infarction, 10.5% stroke. Only 28.6% of laboratory-confirmed cases were diagnosis-coded for CKD in 2011–2019.Conclusion: CKD prevalence was 14.0% in a Hungarian subpopulation of healthcare-utilizing subjects in 2011–2019, and substantial under-reporting of CKD was also found.
Histoire et perspectives du Novum Glossarium Mediae Latinitatis. Un « Nouveau Du Cange »
Authors: Bon Bruno 
Published: March 2023

En 1923, l’Union Académique Internationale (www.uai-iua.org) lançait le «Dictionnaire du Latin Médiéval» , pour remplacer le Glossarium Mediae et Infimae Latinitatis de Charles Du Cange (XVIIe siècle). Le «Nouveau Du Cange» devait être un dictionnaire scientifique moderne, historique et généraliste du latin de toute l’Europe des IXe-XIIe siècles. Pour le réaliser, un réseau européen de lexicographie médiolatine fut constitué. Un siècle plus tard, le projet a évolué : la consultation du Novum Glossarium et des dictionnaires nationaux de l’UAI, complémentaires, permet d’éviter en partie le recours aux dictionnaires de latin classique, sans remplacer entièrement l’ancien Glossarium de Du Cange. La rédaction du Novum Glossarium (IRHT-CNRS), qui doit rendre compte de plus de 10 000 références bibliographiques, est passée du «tout empirique» (dépouillement traditionnel au fil de l’eau) au «tout informatique » : à nouveau support, nouvelles méthodes, fondées sur l’exploitation des corpus textuels numérisés. Au delà de la numérisation rétrospective du Glossarium et des fascicules parus du Novum Glossarium,
déjà réalisée, la perspective d’une publication électronique de la suite du dictionnaire se précise. L’Index scriptorum du Novum Glossarium, converti en SQL et en cours d’indexation, doit servir de base bibliographique. La révolution numérique en cours permet ainsi d’envisager un «Nouveau Nouveau Du Cange», dans le cadre des collaborations engagées autour de projets européens et nationaux, et d’aboutir à la concrétisation du rêve fondateur d’un dictionnaire universel du latin médiéval.

Published: March 2023

Background:
C3 glomerulopathy (C3G) is a rare kidney disease, which makes it difficult to collect large cohorts of patients to better understand its variability. The aims of this study were to describe the clinical profiles and patterns of progression of kidney disease.

Methods:
Retrospective, observational cohort study. Patients diagnosed with C3G between 1995–2020 were enrolled. Study population was divided into clinical profiles by combining the following predictors: eGFR under/above 30 ml/min/1.73m2fn2, proteinuria under/above 3.5 g/day, histologic chronicity score under/above 4. The change in eGFR and proteinuria over time was evaluated in a subgroup with consecutive measurements of eGFR and proteinuria.

Results:
115 patients with a median age of 30 years (IQR 19–50) were included. Patients were divided into 8 clinical profiles. Kidney survival was significantly higher in patients with a chronicity score <4 and proteinuria <3.5g/day, both in those presenting with an eGFR under/above 30 ml/min/1.73m2. Median eGFR slope of patients who reached kidney failure was -6.5 ml/min/1.73m2/per year (IQR -1.6; -17). Patients who showed a reduction in proteinuria over time did not reach kidney failure. Based on the rate of eGFR decline patients were classified as faster eGFR decline (≥5 ml/min/1.73m2/year), slower (<5 ml/min/1.73m2/year), and those without decline. A faster eGFR decline was associated with higher probability of kidney failure.

Conclusions:
Kidney survival is significantly higher in patients with a chronicity score <4 and proteinuria <3.5 g/day regardless of baseline eGFR, and a faster rate of decline in eGFR is associated with higher probability of kidney failure.
Historical prerequisites for the development of other measures of a criminal law nature aimed at restricting the rights of persons committed crimes against the interests of the Russian Federation
Authors: Pirozhnikov Alexander 
Published: March 2023

The relevance of the topic is due to the need for a retrospective analysis of individual measures of state enforcement in order to understand their criminal legal nature. The history of the development of other measures of a criminal law nature in relation to individual groups of crimes is practically not considered in the criminal law literature. Encroachments on the interests of the state the punishment for which has traditionally been one of the most severe among socially dangerous acts prohibited by criminal law are no excluded. Nevertheless, the analysis of historical sources shows that the limits of coercion in this area have changed over time significantly. The changes that took place were related to the policy of the state, namely the humanization of punishment - the mitigation of the means of influence used against persons guilty of committing crimes against the interests of the state. Today, this trend generally continues. Along with the rigidity of the approach, the authorities allow a compromise, reasonably believing that a different impact or border measures can ensure the effectiveness of prevention.
Traditional methods were used in the study organizing - generalization, analysis, analogy.
Results. The development of the criminal law science, as well as the humanism ideas dominance, the human resources economy, led to the implementation of a fundamentally different approach in the entire field of criminal law regulation. We believe that the further development of this area will allow us to determine new prospects for countering the crimes of the group under study.
International experience in the prevention of recidivism by law enforcement agencies
Authors: Smirnov Leonid 
Published: March 2023

Recidivism is a criminal pathology in any country. Its increased public danger consists in formation of professional crime - vanguard of criminality. Within recidivism crime maintains and spreads criminal traditions, develops and reproduces criminal subculture. The impact of criminal recidivism is devastating for vulnerable segments of the population. As a result of its negative impact, criminality is rejuvenated and feminized. The relevance of the presented work lies in the analysis of positive experience of the international community in fighting criminal recidivism. Russian law enforcement and legislation are in dire need of effective anti-recidivism practices. The relevant law enforcement experience in the USA and Israel, as well as European (Azerbaijan, Belarus, Great Britain, Poland) and Asian (China, South Korea, Japan) countries is considered. National mechanisms of resocialization of ex-prisoners, features of probation activities and specifics of post-penitentiary care in foreign countries are described. The forms of international cooperation on counter-recidivism between Russia and foreign countries are reflected. Particular attention is paid to conventional and institutional legal forms.
Legislative and law enforcement measures are proposed to introduce foreign experience in the field of anti-recidivism prevention into law enforcement activities in Russia.
Social-psychological approach to the adaptation of persons under probation: a review of foreign experience
Authors: Zlokazov Kirill 
Published: March 2023

Introduction. The research focuses on improving adaptation measures for offenders under probation. The relevance of the study is determined by the high rates of re-offending of supervised persons caused by the lack of a stable source of income, low level of education, absence of profession or necessary qualification, cessation (breakdown) of relationships, alcohol or drug addictions.
The problem consists in the fact that individual preventive work with supervised persons needs to be improved and that there is a lack of a systemic understanding of how it should be organized. One of the stages of solving the problem is the examination of foreign experience of social adaptation of supervised persons and conceptualization of its theoretical foundations, definition of the subject area, characteristics and parameters.
Research methods: theoretical methods of cognition: generalization, categorization and systematization of information on approaches, theories and concepts on the adaptation of administratively supervised persons.
Results. The author reasons that foreign adaptation programs are based on sociological (structural functional and interactionist) theories and a group of socio-psychological ideas and concepts. Analysis of the programs also reveals the influence of national and cultural specificity on the organization of work with supervised persons. The main directions of adaptation are: (1) restoration of social functioning of this category of persons, carried out by means of legal, social and psychological support, (2) reintegration in the form of controlled involvement into the social relationships existed before the criminal punishment; (3)
social and psychological adaptation aimed at countering criminalization, resocialization and rehabilitation.
Conclusions. The value of social environment in social adaptation of supervised persons is identified. This environment can offer material and social resources that the subject lacks, be a source of expert information, education and psychological support. The author substantiates the need to verify the findings by further operationalizing the characteristics of the social environment in order to objectively assess its ability to implement the adaptation of persons subjected to administrative supervision.
