The Effect Of Microbially Induced Calcite Precipitation (MICP) On Shear Strength Of Coal Contaminated Soil
Authors: Marini Andi , Utomo Gunaedy , Ryka Hamriani 
Published: May 2023

Microbially induced calcite precipitation (MICP) is a soil improvement technique using microorganisms that can change and improve mechanical properties. This technology has been explored and is promising with potential in a variety of applications. Bacillus subtilis bacteria as much as 6% were added to soil contaminated with 5%, 10%, and 15% coal. The bacteria used were cultured for 3 days in growth medium. In this study, a direct shear test was used to determine the effect of calcite deposition on the behavior of the shear strength of coal contaminated soil. The results showed that there was an increase in the value of cohesion and internal friction angle as parameters of shear strength after the curing period. MICP stabilization in soil contaminated with 5% coal resulted in an increase in shear strength of three times, while in soil contaminated with 10% and 15% coal there was an increase in shear strength of seven times and fifteen times, compared to the untreated soil
Transfusion de produits sanguins labiles en réanimation pédiatrique
Authors: Demaret Pierre 
Published: May 2023

Les transfusions de produits sanguins labiles sont indispensables pour la prise en charge adéquate de diverses pathologies. Toutefois, elles ne sont pas sans risques, si bien que leur usage doit être raisonné.
Pour les globules rouges, une stratégie transfusionnelle restrictive, privilégiant des seuils transfusionnels plus bas (hémoglobine 70 g/L) que ce qui était historiquement recommandé (hémoglobine 90-100 g/L), peut être recommandée pour la plupart des enfants admis en réanimation : elle permet de réduire la consommation de concentrés érythrocytaires sans affecter le pronostic des patients. Bien qu’une stratégie plus libérale puisse être envisagée sur base du jugement clinique dans certaines circonstances (incluant l’hypoxémie sévère, l’instabilité hémodynamique, le traumatisme crânien grave ou encore la dysfonction myocardique sévère), aucune donnée solide n’appuie l’intérêt d’une transfusion si l’hémoglobine est supérieure à 100g/L.
Les données de la littérature sont beaucoup plus pauvres pour les transfusions de plasma et de plaquettes en réanimation pédiatrique, si bien que les experts ne peuvent recommander formellement une transfusion qu’en cas d’hémorragie massive, alors qu’ils invitent à utiliser le jugement clinique dans la plupart des autres situations.
La recherche en médecine transfusionnelle doit être poursuivie afin d'obtenir des données permettant de développer des recommandations transfusionnelles davantage basées sur l'évidence.
Management of patients with acute heart failure/cardiogenic shock complicating a valvular disease
Authors: Aguilhon Sylvain , Roubille François , Delmas Clément 
Published: May 2023

Cardiogenic shock (CC) is the most advanced and severe stage of heart failure.
Its management requires a rapid diagnosis, an etiological evaluation and the initiation of an adapted treatment as soon as possible.
Even if ischemic etiology remains preponderant, the prevalence of other causes, notably valvular, is constantly increasing.
In our industrialized countries, aortic stenosis is the most frequent valve disease, followed by mitral insufficiency, aortic insufficiency and mitral stenosis.
While the management of these valvulopathies is well codified and has been evolving over the last few years, acute management is less clear.
Inotropic treatments and mechanical circulatory support are part of the therapeutic arsenal available, but the correction of the valve disease remains the main problem.
Conventional surgery is unfortunately difficult to consider because of its high moribidity and mortality. Percutaneous techniques are therefore an alternative, even if few data are available and their development according to the type of valve disease is uneven.
This update provides an overview of the different valve diseases in the context of CC and summarizes the different therapeutic options available in such a critical situation.

Authors: Chyrzyński Ryszard 
Published: May 2023

ObjectivesAnalysis of the increased financial effort of the state related to the intensification of the process of developing the country's defense potential, including in particular the process of programming and financing the development of the Polish Armed Forces.MethodsTheoretical and empirical scientific methods have been used in the development of this publication. The theoretical methods are analysis and synthesis of source documents and comparative analysis. The empirical method was participant observation of the processes of planning, programming, and budgeting the development of the Polish Armed Forces.ResultsA comparative analysis of various source materials, shaping expenditures on securing the state's defense needs, allowed the author to prove the thesis that an appropriate level of these expenditures can actually improve the overall security of the country, as well as the capabilities of its Armed Forces.ConclusionsThe geopolitical situation that has arisen in recent months around the borders of Poland forces the state to significantly accelerate the process of intensifying the development of the country's defence potential, including technical modernization and development of the Armed Forces. The implementation of the tasks for the security and defence of the state has required many changes for years in relation to:
- the obligation to defend – issues related to qualification, the course of the recruitment process for military service, or the defence duty of citizens;;
- military service – issues related to broadly understood military service;
- programming and financing of the Armed Forces – issues related to obtaining new sources of financing;
- implementation of tasks by entrepreneurs for the armed forces – issues related to the change in the design, financing and competence of government administration bodies.

Giving guidance to young learners needs a specific strategy that fixes to their needs and world. This social service was conducted from May up to June for all parents who jlin in the organization of teachers and parents in SDIT Alif Smart Surakarta. We have three methods in conducting this activity: (1) Need Analysis, which was done by interviewing parents about their way of accompanying their children in learning English at home, and (2) Socialization about contextual teaching and learning in learning English. It was done by giving material explanation about the notion, steps, and implementation of contextual teaching and learning in learning English at home in accordance to their daily life; and (3) Feedback. This was done by giving feedback about the implementation of contextual teaching and learning in daily life English at home. At first, we coordinated the activity. And secondly, there’s a meeting to encourage all members to have motivation besides giving material for them. The material is all about the implementation of contextual teaching and learning in guiding children to learn English at home. In fact, we discussed how to help all children to learn English and deal with their daily life. There are also questions and answers about how to guide children to learn English effectively and how to solve problems in learning English.

Abstract
We report the detection and interferometric localization of the repeating fast radio burst (FRB) source FRB 20220912A during commissioning observations with the Deep Synoptic Array (DSA-110). Two bursts were detected from FRB 20220912A, one each on 2022 October 18 and 2022 October 25. The best-fit position is (R.A. J2000, decl. J2000) = (23:09:04.9, +48:42:25.4), with a 90% confidence error ellipse with radii ±2″ and ±1″ in R.A. and decl., respectively. The two bursts are polarized, and we find a Faraday rotation measure that is consistent with the low value of +0.6 rad m−2 reported by CHIME/FRB. The DSA-110 localization overlaps with the galaxy PSO J347.2702+48.7066 at a redshift z = 0.0771, which we identify as the likely host. PSO J347.2702+48.7066 has a stellar mass of approximately 1010
M
⊙, modest internal dust extinction, and a star formation rate likely in excess of 0.1 M
⊙ yr−1. The host-galaxy contribution to the dispersion measure is likely ≲50 pc cm−3. The FRB 20220912A source is therefore likely viewed along a tenuous plasma column through the host galaxy.

Published: May 2023

Abstract
The evolutionary relationships and mechanisms governing the behavior of the wide variety of luminous stars populating the upper H-R diagram are not well established. Luminous blue variables (LBVs) are particularly rare, with only a few dozen identified in the Milky Way and nearby galaxies. Since 2012, the Barber Observatory Luminous Stars Survey has monitored more than 100 luminous targets in M33, including M33C-4119 which has recently undergone photometric and spectroscopic changes consistent with an S Doradus eruption of an LBV.
VIOLÊNCIA NO ENSINO SUPERIOR

Published: May 2023

O presente artigo de revisão bibliográfica, tem como objetivo compreender as manifestações de violência no ensino superior, tendo como base teórica a Teoria Crítica da Sociedade, especialmente os estudos de Theodor W. Adorno. Foi realizada uma busca de artigos e pesquisas sobre a temática na base de dados da SciELO, na plataforma google acadêmico e no Catálogo de Teses e Dissertações da CAPES, em oito de abril de 2022 e para a sistematização dos dados foi utilizada a análise de conteúdo proposta por Adorno (2008). Como resultado, foram encontrados quatro artigos e uma dissertação que coadunam com a proposta da presente revisão, pois retratam as formas de violência que se manifestam no ensino superior, como o trote, o bullying e o preconceito, sendo estes últimos modos mais regredidos para a expressão da agressividade psíquica, o que evidencia que a verticalização da educação não garante o desenvolvimento global e que a universidade revela uma estrutura social que tem como base a dominação.
Insights into dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) distribution along an elevational gradient in a tepui table-top mountain in the Brazilian Amazon

Published: May 2023

Abstract
Elevational gradients are excellent models to understand species distribution across sites with marked shifts in environmental conditions. In northern South America, tepuis are table-top mountains with elevations above 1000 m and high biodiversity and endemism levels. In this study, we assessed the effect of elevation on dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) assemblage structure (species richness, abundance, and biomass) in Tepequém, a tepui located in northern Brazil. Dung beetles were sampled with pitfall traps within seven elevational bands from 250 to 850 m. A total of 83 individuals from 14 species were collected, Oxysternon festivum (Linnaeus, 1758) and an unidentified Onthophagus species being the most abundant. Elevation did not affect beetle species richness and biomass. However, species composition from 750 to 850 m differed statistically from that recorded at lower elevations. Our results suggest that beetle assemblages possess a bimodal distribution along an altitudinal gradient on the Tepequém. The contrasting vegetation structure of tepuis between highlands (shrubland savannah vegetation) and lowlands (tropical rainforest) explains the different composition of the assemblages. This study should be considered as a starting point in improving our understanding of the dung beetle diversity of tepuis, which present a unique singular relationship between elevation and species diversity.
Spi-C and PU.1 Counterregulate Rag1 and Igκ Transcription to Effect Vκ-Jκ Recombination in Small Pre-B Cells

Published: May 2023

Abstract
B cell development requires the ordered rearrangement of Ig genes encoding H and L chain proteins that assemble into BCRs or Abs capable of recognizing specific Ags. Igκ rearrangement is promoted by chromatin accessibility and by relative abundance of RAG1/2 proteins. Expression of the E26 transformation-specific transcription factor Spi-C is activated in response to dsDNA double-stranded breaks in small pre-B cells to negatively regulate pre-BCR signaling and Igκ rearrangement. However, it is not clear if Spi-C regulates Igκ rearrangement through transcription or by controlling RAG expression. In this study, we investigated the mechanism of Spi-C negative regulation of Igκ L chain rearrangement. Using an inducible expression system in a pre-B cell line, we found that Spi-C negatively regulated Igκ rearrangement, Igκ transcript levels, and Rag1 transcript levels. We found that Igκ and Rag1 transcript levels were increased in small pre-B cells from Spic−/− mice. In contrast, Igκ and Rag1 transcript levels were activated by PU.1 and were decreased in small pre-B cells from PU.1-deficient mice. Using chromatin immunoprecipitation analysis, we identified an interaction site for PU.1 and Spi-C located in the Rag1 promoter region. These results suggest that Spi-C and PU.1 counterregulate Igκ transcription and Rag1 transcription to effect Igκ recombination in small pre-B cells.
Comparison of novel clinic-based approach (amblyopia school) Vs. home-based occlusion for amblyopia therapy – A retrospective study
Authors: Bhattacharya Subhajit , Subhedar Ketaki , Bhadauria Madhu , Shukla Ranjana , Manaktala Ruchita , Kumar Abhinav , Wilson Ayush 
Published: May 2023

Purpose:
To compare visual outcomes of standard occlusion therapy at home versus clinic in amblyopic children.

Methods:
A retrospective study of case records of children aged <15 years with diagnosis of strabismic or anisometropic amblyopia or both was conducted at a tertiary eye hospital located in rural North India between Jan 2017–Jan 2020. Those with at least 1 follow-up visit were included. Children with ocular co-morbidities were excluded. Treatment in clinic by admission or at home was based on the parents’ discretion. Children in clinic group underwent part time occlusion & near work exercises for minimum 1 month, in classroom format which we called amblyopia school. Those in home group underwent part time occlusion as per PEDIG recommendations. Primary outcome measure was improvement in number of Snellen’s lines at the end of 1 month & at final follow-up.

Results:
We included 219 children with mean age of 8.8±3.23 years, out of which clinic group had 122 (56%) children. At one-month, visual improvement in clinic group (2.1±1.1 lines) was significantly greater than home group (mean=1.1±0.8 lines) (P < 0.001). Both groups continued to improve vision on follow-up, however the vision in the clinic group (2.9±1.2 lines improvement at mean follow-up of 4.1±1.6 months), continued to be better than home group (2.3±1.1 lines improvement at mean follow-up 5.1±0.9 months) (P = 0.05).

Conclusion:
Clinic based amblyopia therapy in the form of an amblyopia school can help expedite visual rehabilitation. Thus, it may be a better option for rural settings where patients in general tend to be poorly compliant.
Sub-Bowman keratomileusis versus femtosecond laser in situ keratomileusis on the long-term visual recovery: A comparative study
Authors: Feng Yi , He Rui , Qu Min , Ma Qiuxia , Tian Huiqin 
Published: May 2023

Purpose:
To explore the long-term visual quality of the same subjects after sub-Bowman keratomileusis (SBK) or femtosecond laser in situ keratomileusis (FS-LASIK).

Methods:
This prospective study included patients screened for corneal refractive surgery at the Refractive Surgery Center of our Hospital between November 2017 and March 2018. One eye underwent SBK, while the other eye underwent FS-LASIK. Total higher-order aberrations, coma aberrations, and clover aberrations were evaluated before and at 1 month and 3 years after the procedure. The visual satisfaction of both eyes was investigated, respectively. The participants completed a surgical satisfaction questionnaire.

Results:
Thirty-three patients were included. There were no significant differences in total higher-order aberrations, coma aberrations, and clover aberrations between the two procedures before and 1 month and 3 years after surgery (all P > 0.05), except for the total coma aberrations in FS-LASIK were significantly higher compared with the SBK group at 1 month after surgery [0.51 (0.18, 0.93) vs. 0.77 (0.40, 1.22), P = 0.019]. The surgical satisfaction questionnaire scores of the SBK group and the FS-LASIK group were 9.8 ± 0.8 and 9.8 ± 0.8, respectively, at 1 month, and 9.7 ± 0.9 and 9.7 ± 1.0, respectively, at 3 years (all P > 0.05).

Conclusion:
There were no differences in corneal aberrations and satisfaction between SBK and FS-LASIK procedures at 1 month and 3 years.

Authors: Chavan Amruta , Gogate Parikshit , Wagh Shailesh , Telap Sharad , Phadke Supriya , Chandore Sonali , Avhad Komal , Gogate Siddharth , Naidu Purshottam 
Published: May 2023

Purpose:
To assess the need for spectacles and low-vision aids (LVA) in students attending schools for the blind and study their compliance with use.

Methods:
Comprehensive ocular evaluation was performed using a hand-held slit lamp and ophthalmoscope. Vision acuity was measured using a logarithm of the minimum angle of resolution (logMAR) chart for distance, as well as for near. Spectacles and LVAs were dispensed after refraction and LVA trial. Follow-up was performed to assess the vision using the LV Prasad Functional Vision Questionnaire (LVP-FVQ) along with compliance with use after 6 months.

Results:
Of the 456 students examined from six schools, 188 (41.2%) were female; 147 (32.2%) were <10 years of age. In all, 362 (79.4%) were blind since birth. The students dispensed only LVAs were 25 (5.5%), only spectacles were 55 (12.1%), and both spectacle and LVAs were 10 (2.2%). The vision improved using LVAs in 26 (5.7%) and using spectacles in 64 (9.6%). There was a significant improvement in LVP-FVQ scores (P < 0.001). Also, 68/90 students were available for follow-up, of whom 43 (63.2%) were compliant to use. Causes of not wearing spectacles or LVA in 25 were left somewhere or lost 13 (52%), broken 3 (12%), uncomfortable to use 6 (24%), not interested to use 2 (8%), and got operated 1 (4%).

Conclusion:
Although the dispensing of LVA and spectacles improved the visual acuity and vision function of 90/456 (19.7%) students, nearly a third were not using them after 6 months. Efforts need to be taken to improve the compliance of use.

Authors: Jain Mukesh , Narayanan Raja , Gopal Lingam , Padhi Tapas R , Behera Umesh C , Panda Krushna G , Tabasum Runa , Banjare Nadeem K 
Published: May 2023

Purpose:
We report clinical characteristics, risk factors, treatment outcomes, and prognostic predictors of post-vitrectomy secondary macular holes (MHs).

Methods:
This was a retrospective observational case series from November 2014 to December 2020. Eyes that developed secondary MH, two weeks and beyond after primary vitrectomy for non-MH indications, were enrolled. Pre- and intraoperative records were screened to exclude pre-existence of MH. Eyes with multiple vitreoretinal surgeries prior to MH detection and tractional myopic maculopathy were excluded.

Results:
A total of 29 eyes of 29 patients with a mean age of 52 years developed secondary MH post-vitrectomy. The most common indications for primary vitrectomy were rhegmatogenous retinal detachment (RRD, 48.2%) and tractional retinal detachment (TRD, 24.1%). Time to MH detection after primary vitrectomy was 91.5 ± 117.6 days. The mean minimum hole diameter was 530 ± 298 microns. Epi-retinal membrane and cystoid degeneration was noted in 6 (20.7%) and 12 (41.3%) eyes, respectively (p = 0.088). The mean time from MH detection to MH repair was 34 ± 42 days. The surgical intervention included internal limiting membrane peeling with tamponade in 25 eyes. Overall, 80% showed anatomic hole closure, 90.9% versus 57.1% in the RRD and TRD (p = 0.092), respectively. The mean best-corrected visual acuity (BCVA) at the final visit was 0.71 logarithm of the minimum angle of resolution. Thirteen eyes (52%) had a BCVA of 20/100 or better. Minimal hole diameter (p = 0.029) only predicted final visual acuity. The interval between MH diagnosis and repair did not affect hole closure significantly (p = 0.064).

Conclusion:
Secondary MH post-vitrectomy closed successfully with limited visual improvement and trails behind idiopathic MH.
