New contribution to Luria–Delbrück distribution. Stability property and estimation
Authors: Boughrara Sabrina , Bedouhene Fazia , Zougab Nabil

Abstract
The multiplication of cells leads to consider the cell division model with mutation. Large cell counts therefore appear, implying that the distribution of the final number of mutant cells is a heavy tailed distribution. This distribution can be interpreted as a compound Poisson distribution, which depends on two parameters: the average number of mutations and the fitness parameter (heavy tail index). In this work, we specify some conditions that ensure a stability property of heavy-tailed distributions, namely, the distribution of random sum of random variables is a heavy-tailed distribution. We apply the obtained result to the compound Poisson distribution. To estimate the tail index, the Hill estimator and the generating function method are used. A comparative study is performed using these two estimators.

Abstract
The advancement of catheter-based interventional techniques represents a significant evolution in cardiovascular medicine. However, traditional methods that rely on fluoroscopic guidance present considerable limitations including radiation exposure and contrast agent-related risks and the heavy load-caused lead suits. In response, zero or low X-ray emerge, including percutaneous and non-fluoroscopical (PAN) procedure coming as a transformative solution, particularly in treating congenital heart disease, valvular disease, and arrhythmias. These methods minimize the risk of iatrogenic injuries associated with radiative procedures. Innovative PAN procedures and methodologies have been developed to enhance imaging, transcatheter interventions, safety, and accuracy, overcoming previous limitations. By eliminating radiation and expanding accessibility, PAN procedures offer a safe, effective, and economically viable alternative to traditional methods, ushering in a new era of minimally invasive cardiovascular treatment.
Characterising the mechanical behaviour of dry-formed cellulose fibre materials
Authors: Kaplan Magdalena , Johansson Adam , Östlund Sören 
Published: January 2025

Abstract
In the dry-forming process, paper pulp is formed without adding water, making it more resource-effective than traditional papermaking. It is a relatively new technology, patented only in recent years, and very few material investigations exist in the literature; hence, little is known of the constitutive behaviour. The stress state during forming is highly complex, including multiaxial loading, extreme densification, friction, large strains, and fibre-joint formation. This paper studies dry-formed materials at different compression levels, from the sparse mat to the highly densified network. Three primary loading modes are investigated: in-plane tension, out-of-plane shear and out-of-plane compression. The results indicate that the tensile modulus and strength scale quadratically and cubically to the density, respectively, while the shear properties start developing after the density passes a threshold value. The compressive properties proved difficult to quantify, mainly because of the discrepancy between the density before and after the compressive test. The dry-formed material was compared to wet-formed paper materials in the literature. This showed that the in-plane (tensile) properties and the out-of-plane shear strength are visibly lower while the shear stiffness is similar, compared to wet-formed materials. Nonetheless, the findings set a starting point for numerical simulations of the dry-forming process.
The management of body dysmorphic disorder in adolescents: A systematic literature review
Authors: Ghosh Tania , Blair Erik 
Published: January 2025

Abstract
Body dysmorphic disorder (BDD) is a pathological body dissatisfaction characterised by delusional beliefs of a flaw in appearance paired with obsessive-compulsive rituals. This disorder has a high prevalence in adolescence. This study examines the current state of treatment for BDD in adolescents in the UK to establish a baseline of current treatment, and to identify specific areas for further research. A systematic literature review of two databases was carried out and resultant papers were organised using an amended version of the current UK management standards. Six papers met the eligibility criteria and cognitive behavioural therapy was reported as the most effective current treatment. In drawing together the key findings, three areas for further research were highlighted that are of relevance to a broad range of clinicians working in BDD management in adolescence. These included inquiry into mental health professionals’ perspectives, a review of the rate of remission rates, and research into the extent to which schools can influence adolescents’ ideas about body image. The significance of BDD is not reflected in the current literature base. Education of professionals and the wider community is warranted, as is the drive for improved awareness and an increase in the availability of treatment.

Abstract
Global agriculture feeds over seven billion people and alarmingly, this number is expected to increase by a further 50% by 2050. To meet the additional food demand, the world development report has estimated that crop production should increase by 70–100% by 2050. However, climate change, expanding soil salinization, and the developing shortages of freshwater have negatively affected crop production of edible plants around the world. Current attempts to adapt to these conditions include the use of salt-tolerant plant species with potential economic value to fulfil the increasing food demand escalated by the increasing human population. The wild edible halophyte Tetragonia decumbens commonly known as dune spinach has the potential to be used as a leafy vegetable, a source of dietary salt, in phytoremediation and as a source of secondary metabolites. However, it remains underutilized in South Africa as commercial farming of this species has never been explored. This review examined the potential of domesticating the wild dune spinach as a leafy vegetable, describing its morphology and ecology, its propagation and cultivation requirements as well as its potential use on human health and in phytoremediation of saline soils. Furthermore, this analysis is expected to be useful towards further research and popularization of this underexploited halophyte.

La investigación estuvo orientada a determinar las evidencias psicométricas del Cuestionario de Agresión, forma reducida (AQ-SF). Participaron adolescentes de 12 a 17 años, divididos en dos grupos [n1 = 332 (Medad = 14.08, DEedad = 1.30, de 12 a 14 años = 61.4 %, mujeres = 55.4 %) y n2 = 336 (Medad = 14.07, DEedad = 1.31, de 12 a 14 años = 62.5 %, mujeres= 56 %). Se halló que el AQ-SF presenta evidencias de validez basada en la estructura interna y de equidad por sexo y edad, pero presenta fiabilidad inaceptable en las dimensiones de agresión verbal e ira. En contraste, la versión propuesta del AQ-SF (AQ-SFb), además de las evidencias de validez y equidad, presenta evidencias de fiabilidad por dimensiones, especialmente en un formato de seis opciones de respuesta. Finalmente, se concluye que la versión propuesta (AQ-SFb) tiene más evidencias psicométricas que el AQ-SF en adolescentes peruanos.

Every day, around 7% of population will experience headache caused by migraine. Migraine is one of the leading causes of years lived with disability, and it also causes significant negative economic impact, as most as the affected population is of working age. Pathogenesis of migraine includes neurogenic inflammation, which, in turn, causes peripheral sensitization of trigeminal nerve mechanoreceptors. As peripheral sensitization lingers on, central sensitization of the spinal trigeminal nucleus occurs. Non-steroidal anti-inflammatory drugs and triptans are first line treatment of a migraine attack. Nevertheless, when used in combination, these medications deliver a synergistic action. In this article, we review a combination of sumatriptan and naproxen sodium for the treatment of migraine headache as an underused treatment option in Lithuania.

Authors: Lacerda Giovana 
Published: January 2025

Entre 2013-2022 houve um aumento de 103% das vagas de medicina. Referente a esse crescimento, é interessante notar a diferença entre as faculdades privadas e públicas: de 2003-2023, o crescimento das faculdades públicas correspondeu a 64%, enquanto para as privadas correspondeu a 358%. Esse rápido crescimento comprometeu a qualidade dos cursos, de modo que 92% das faculdades não cumprem critérios do Conselho Federal de Medicina. O objetivo deste trabalho é entender as motivações dos médicos para a escolha da profissão e especialidade, o uso de redes sociais na prática médica, e as expectativas salariais, comparando-as com a realidade do mercado de trabalho, particularmente entre os médicos da capital e do interior. A pesquisa foi realizada por meio de questionários elaborados a partir de uma revisão bibliográfica. O questionário abordou variáveis como situação socioeconômica, motivação para a escolha da medicina, especialidade, expectativa salarial, e uso de redes sociais. A amostra foi composta por 167 médicos, e os questionários foram enviados online. Sobre os resultados, quanto ao trabalho no interior, 36,3% dos médicos estariam dispostos. Os que utilizam redes sociais correspondem a 41,2% dos médicos, sendo que mais de 50% dos profissionais de cirurgia plástica as utilizam. Em relação à expectativa salarial no ápice da carreira, 50% dos médicos esperam um salário superior a 20 salários mínimos. Em conclusão, a pesquisa evidencia uma preferência dos médicos pela capital, especialmente devido à rentabilidade das especialidades e à atenção terciária. Não há um crescimento na utilização das redes sociais ao longo dos últimos anos, pois percebe-se um delineamento em seu uso nas especialidades, vide a predominância de médicos cirurgiões plásticos que as utilizam.

The article presents the analysis of the first comprehensive volume of memoirs Cała siła, jaką czerpię na życie. Świadectwa, relacje, pamiętniki osób LGBTQ+ [All the Power I Draw for Life. Testimonies, Accounts, Memoirs of LGBTQ+ People in Poland] (2022). It is a landmark volume in many respects. It is the first of its kind, a comprehensive (nearly 1,000 pages) selection of memoirs that were sent to a competition announced in 2020 by the LGBT+ History and Identities Research Laboratory at the Institute of Applied Social Sciences at the University of Warsaw. Therefore, they have become part of the long Polish tradition of diaries written for a competition announced by state institutions, a tradition dating back to the interwar period (diaries of peasants, Jewish youth, the unemployed, etc.). At the same time, the diaries were published at a very politically sensitive moment, when homophobia became an element of global politics, including the construction of East/West European distinctions. The published collection of diaries thus becomes a unique, autonomous and empowered voice of the LGBTQ+ community from Central and Eastern Europe in a contemporary, hostile, geopolitical context.

This experiment was carried out to evaluate the response of two upland rice varieties to incorporation of 6-benzylaminopurine (6-BAP) into the traditional fertilizer program. Treatments were laid out in a randomized complete block design (RCBD) in 2 x 5 x 2 factorial including 2 upland rice varieties (NERICA 3 (N3) and NERICA 8 (N8)), 5 treatments notably T0 = Controls (NPK 20:10:10 and Urea 46%), T1 = 6-BAP (25mg/l), T2 = 6-BAP (50mg/l), T3 = 6-BAP (75mg/l) and T4 = 6-BAP (100mg/l) all repeated twice. All the treatments received NPK (20:10:10) + Urea 46% while application of T1 to T4 started at the flag leaf stage and was done in 3 splits of foliar sprays. The results revealed that 6-BAP significantly influenced mean number of stay green tillers/m2 at 120 days after transplanting with corresponding scores of 16, 87.5, 111, 110 and 127 for T0, T1, T2, T3 and T4 in Nerica 3. Maximum paddy yield in N3 were 8.37 and 4.49 t/ha respectively for T3 and T0 while in N8, paddy yields were 7.36 and 4.6 t/ha correspondingly for T4 and T0. In N3, broken grains rate after milling was 34.45 and 26.30 % individually for the control and T3 while in N8 grain breaking rate of 28.81 and 25.16 % were respectively scored by T0 and T3. This study reveals that, foliar spray of 6-benzylaminopurine at 75 mg/l in three splits of 7 days during flag leaf stage optimizes upland NERICA yields and grain morphological characteristics after milling.
Mini-review: the utility of macroalgae in abalone diets and their role in heat resilience

Published: January 2025

Abalone aquaculture production is predicted to continue to increase. Nutrition and health aspect are becoming two major issues that can impede the development and economic sustainability of abalone aquaculture industries. Feeding fresh macroalgae to abalone has supply inconsistency and biosecurity issues in the culture system. The utilization of commercially formulated diets could improve abalone growth rates. However, in general, the health condition of abalone which has been fed commercially formulated feeds was lower than abalone fed fresh macroalgae diets. An abalone diet should not only need to sustain a high growth rate but also promote optimal health. The use of dried macroalgae meal as a dietary ingredient in formulated diets for abalone could potentially increase growth rate, reduce feed costs and gain the health and immunity benefits of macroalgae. This review aims to improve understanding of the potential benefits of using fresh and dried marine macroalgae as feed ingredients to provide nutritional and health improvements for abalone.

ABSTRAK

Produksi budidaya abalon diperkirakan terus meningkat. Aspek gizi dan kesehatan menjadi dua isu besar yang dapat menghambat perkembangan dan keberlanjutan ekonomi industri budidaya abalon. Pemberian pakan makroalga segar ke abalon memiliki permasalahan pada ketersediaan pasokan yang tidak konsisten dan biosekuriti dalam sistem budidaya. Pemanfaatan pakan komersial dapat meningkatkan laju pertumbuhan abalon. Namun secara umum, kondisi kesehatan abalon yang diberikan pakan formula komersial lebih rendah dibandingkan dengan abalone yang diberikan pakan makroalga segar. Pakan abalon sebaiknya tidak hanya perlu meningkatkan pertumbuhan tetapi juga meningkatkan kesehatan yang optimal. Penggunaan tepung makroalga kering sebagai bahan makanan dalam formulasi pakan abalon berpotensi meningkatkan laju pertumbuhan, mengurangi biaya pakan dan mendapatkan manfaat kesehatan dan kekebalan dari makroalga. Kajian ini bertujuan untuk meningkatkan pemahaman tentang potensi manfaat penggunaan makroalga laut segar dan kering sebagai bahan pakan untuk memberikan peningkatan nutrisi dan kesehatan abalon.

Published: January 2025

The purpose of adding metallic fibers (filiform elements) to cementitious matrices is to increase the toughness of these brittle materials. The lateral confinement technique, using spiral reinforcement or stirrups, is capable of increasing the compressive strength of the confined core of cement matrices. Thus, this work aimed to use helical metal fibers (two-dimensional elements) with the aim of increasing both the toughness and the compressive strength of concrete. So, an experimental program was carried out in order to determine the compressive strength and residual strength (toughness index) of five types of concrete, varying the volume fraction of helical metal fibers from 0 (reference concrete) to 2%, every 0.5%. The results obtained indicated that the helical metal fibers were able to increase the residual strength of concrete by up to 30% (concrete with 2% of helical fibers), these increases being linear and directly proportional to the amount of fibers added, but they did not have a significant influence on the compressive strength of the final products. However, more tests need to be carried out, varying the helical fiber parameters, to confirm these preliminary results.

Social safety nets programs are not just assistance programs but these are significant elements for building and strengthening social contracts between states and citizens. The safety nets programs are used for the help of deprived segment of the society. Some theorist argues that these safety net schemes are utilize for making vote bank. This study was interested to contribute these debates through an analysis of cash grant scheme of BISP introduced by Pakistan People Party in 2008 BISP has received a tremendous support from the World Bank, USAID, ADB and DFID This study explores how the cash grant of BISP program is used by PPP for making vole bank. Case Study method was adapted to conduct this research study. District Nowshera was taken as a case for the analysis of the BISP scheme. Data is collected from primary and secondary sources Interview is used as a tool for data collection Numbers of persons of different cadres were interviewed for the sake of data collection in district Nowshera. After interviewing a number of persons randomly in district Nowshera, a lot of issues were found. These issues include technical and political issues. Technical issues include lope holes of BISP Poverty Score Card, fake forms and data steeling, fake call and SMS, ill- behavior and choice commission at Easy Paisa shops, Fake BISP forms selling, Ill -behavior of BISP staff, use of ATM Cards, issues in BVS (Biometric Verification System), and hurdles in getting stipend. While politically it was found that PPP utilized the name of former Prime Minister Benazir Bhutto late for making vote bank. They got the sympathies of public by utilizing her name. The beneficiary's selection survey was also biased. All the surveyors were belonged to PPP. The political interference was involved in the survey. All the selection had done on politician's choice. Favoritism and nepotism were the rule of the day. All the key position holders in BISP program were belonged to PPP. Billions of rupees were spent by propagating this scheme for making vote bank. This study has concluded that the BISP program of cash grant has used for clientelistic politics by Pakistan People Party.
Experimental Investigation of Factors Affecting Oil Recovery and Displacement Efficiency of CO2 Injection in Carbonate Reservoirs
Authors: Masalmeh S. K. , Farzaneh S. A. , Sohrabi M. , Alhammadi M. 
Published: January 2025

Summary
Miscible gas injection is the most widely applied enhanced oil recovery (EOR) method in light oil carbonate reservoirs as a tertiary and secondary method. Miscible gas has high displacement efficiency and usually results in a low residual oil saturation (Sorm) in the parts of the reservoirs that are in contact with the gas. Accurate determination of Sorm and understanding the parameters that affect displacement efficiency are crucial for successful miscible gas EOR projects.
In this paper, we present a comprehensive experimental program designed to investigate the effect of a number of parameters on oil recovery, displacement efficiency, and Sorm of miscible and near-miscible carbon dioxide (CO2) injection. The parameters investigated in this study are the experimental pressure, pore volume (PV) injected, injection rate, rock type, and initial water saturation (Swi). The coreflood experiments were performed using live crude oil at pressures starting below the minimum miscibility pressure (MMP) to pressure well above the MMP, using reservoir core samples of up to 1 ft long and 2 in. diameter. All CO2 injection experiments were performed using vertically oriented cores, with gas injection from the top to ensure stable displacement.
The experimental results show that (1) Oil recovery decreases as pressure decreases with Sorm increasing by more than 20 saturation units as the pressure decreases from 4,250 psi to 2,700 psi; (2) CO2 breakthrough was much earlier at lower pressure, which leads to more CO2 recycling and potentially lower CO2 sequestration volume; (3) the recovery factor (RF) is strongly affected by the PV injected, and this effect is much more significant for the experiments performed at lower pressure; (4) the injection rate has an insignificant impact on oil recovery and Sorm for miscible or near-miscible CO2, due to the low interfacial tension (IFT) between oil and CO2; (5) rock heterogeneity has a strong effect on oil recovery and CO2 breakthrough and hence on CO2 recycling and economy of the projects; and (6) the presence of mobile water at the beginning of CO2 injection resulted in lower displacement efficiency and increased Sorm. However, this water blocking effect should be determined experimentally for a given reservoir rock/fluid system. The results of this study cannot be generalized for other reservoirs.
The results of this study have important implications for the design and performance predictions of CO2 injection in the reservoirs under study. Starting CO2 injection at reservoir pressure, which, in some cases, is more than 1,500 psi above MMP, is recommended due to its superior displacement efficiency and less CO2 recycling due to later breakthrough. However, a higher pressure may negatively impact the required CO2 volume, the compression cost, and project economics.
