To produce high strength or rich cement concrete having low water to cement ratio with adequate workability is the biggest challenge for the construction industry. To achieve the necessary workability, the world is now using costly chemical admixtures. Research should be carried out to explore materials having potential to be utilized as costeffective chemical admixtures in concrete. The primary goal of this research is to investigate the combined effect of Cordia Gel (CG) and Waste Engine Oil (WEO) as chemical admixtures on fresh and hardened properties of concrete. Fresh properties of concrete were examined in terms of workability and hardened properties were investigated by compressive strength test and Ultrasonic Pulse Velocity (UPV) test on cubical specimen of dimensions 100mm x 100mm x 100mm after 7, 28 and 90 days of curing in water. Four different percentages of WEO (0.5%, 1%, 1.5% and 2%) were used and percentage of CG kept constant as 0.5% with respect to weight of cement and results were compared with the control mix. Results revealed that workability of fresh concrete increased with increasing amount of CG and WEO. However, a decreasing trend was observed for compressive strength and UPV of hardened concrete when higher values of admixtures were added. The usage of CG and WEO as chemical admixtures in concrete can be a sustainable and cost-effective way to achieve the desired results

Zirconia-based materials have emerged as promising resources for dental restoration applications owing to their excellent strength and aesthetic appearance. In clinical practices, surface treatment on zirconia is essential to ensure enhanced dental bonding. In this study, a novel method was used to produce zirconia block, and the influence of surface treatment on zirconia-dentine microstructure bonding interface was investigated for different particle sizes of zirconia powder. The particle sizes used in this study were 90 and 30 nm on the basis of manufacturer claims. A zirconia block of both particle sizes underwent surface treatment airborne-particle abrasion (50 μm, 0.4 MPa). Dentine specimens were prepared from extracted premolars stored in 0.1% tymol solution before being randomly cemented with the zirconia block sample by using self-adhesive resin cement (RelyX U2000 Clicker, 3M) and then light polymerised. The results after surface treatment showed higher surface roughness values for 90 and 30 nm at 0.17 and 0.18 μm, respectively, than those of the sample without surface treatment at 0.05 and 0.06 μm, respectively, showing no significant difference between particle sizes. Surface treatment improved the bonding of zirconia because the surface roughness allowed for enhanced interlocking of the cement onto the zirconia surface. However, the unbonded dentine and cement was due to the existence of a smear layer on the dentine surface that prevented the selfadhesive resin cement to work well with the dentine surface. Thus, dentine primer must be used to chemically remove the layer and allow for proper bonding between the resin cement and dentine surface.

Globally, current research has developed new cement-based materials to meet increased demands for performance, energy efficiency, and environmental protection. Geopolymer, cost-effective, and high-early strength concrete binder alternative, has grown in popularity. Geopolymer reduces emissions by 80% during production while maintaining strength levels comparable to Ordinary Portland Cement (OPC). In their natural state, geopolymer binders have a microstructure that is cross-linked and significantly more brittle than OPC. To improve the properties of geopolymer, several approaches were adopted. However, recent study suggests that incorporating nanomaterials such as graphene oxide (GO) to geopolymer has shown an improvement in physical and mechanical properties. Graphene oxide is an inorganic nanomaterial that improves the mechanical characteristics of various composite materials by showing substantial filling effects on composite materials that significantly improve composite material integrity. The investigation into the potential of GO to improve the efficacy of geopolymer composite materials in various engineering applications has garnered considerable attention in recent years. The simplified hummer’s method was employed to synthesise the GO. Various characterization techniques involving SEM, XRD, and FTIR were utilized to understand the crystalline structure and microstructure of GO nanoparticles. GO powder were used as 0.05%, 0.10%, 0.15%, 0.20%, and 0.25% by weight of binder that includes fly ash class F and steel slag with an optimum binder modification of 40% fly ash and 60% steel slag. The influence of GO on Bulk density, microstructure, and mechanical strength were determined. The compressive strength results indicated an improvement of compressive strength by 21.48% in geopolymer paste with 0.15% GO after 28 days of curing.

Food waste has an influence throughout the whole food supply chain, from production to consumption. Composting effectively and affordably reduces the need for synthetic fertilizers, water, soil erosion, pesticides, and soil carbon storage. Composting may also improve crop yields and soil fertility, leading to more sustainable farming practices. The potential of efficient microorganisms (EM) for dehydrated food waste decomposition was investigated in this study. The research assessed the temperature and pH profiles during composting, whereas nitrogen, phosphorus, potassium, organic content, and E. coli were measured in mature composts. Therefore, the study revealed that EM greatly hastened the composting process by boosting critical factors such as temperature, pH, nitrogen content (TN : 1.17±0.6%, TP: 0.059±1.92%, K: 0.12±5.3%) organic enrichment (85%), and E-coli (<1 MPN/g). The germination index (GI) of kale seed was then analysed with the study’s findings indicating an 80% soil-compost ratio was the best. This research investigates the use of effective microorganisms (EM) to transform food waste into beneficial agricultural resources, with favourable results for soil health and kale seed germination. Researchers and circular economy officials may use the results to promote sustainable agriculture. The research helps to minimize landfill food waste, methane emissions, and synthetic fertilizer consumption, all of which benefit the environment. Farmers and gardeners may use the findings to boost soil fertility and crop yields on a budget. This research indicates that food waste may be transformed into useful resources, encouraging sustainable and eco-friendly agricultural.

Authors: Selvaraj Shalini , Sandaran Shanti C.
Published: July 2024

Media representations of aging and older adults is an influential platform for shaping public discourse about aging related matters. Previous research has highlighted that the media’s depictions of older adults are often limited and biased. Such representations significantly influence society’s perceptions of the aging population. With population aging being currently a global social concern, such negative representations raise critical questions about media’s portrayal of aging related matters. Taking on the view that aging is a socially constructed phenomenon, we undertake a Discourse Analysis of 83 online news reports on aging from May 2022 to May 2023, from Malaysia’s high readership online newspaper, The Star. The results unveil several dominant discourses associated with aging, such as discourse of implications, positive aging and negative aging. The study provides valuable insights into the language used and the portrayal of aging populations in newspapers which play a vital role in shaping societal perceptions of aging, which can be either favourable or detrimental for the aging population’s self-worth and dignity. We advocate for more positive portrayals using inclusive language that is crucial for developing a cultural mindset that appreciates and honours the dignity of older members of society.

El aumento de la esperanza de vida y que la generación Baby Boom se esté aproximando a una edad adulta mayor, precisará de unos cambios en las políticas sociales. En este aspecto, la promoción de un envejecimiento activo y saludable es vital. Para ello, resulta necesario contemplar todas las perspectivas del envejecimiento para así trabajar desde un enfoque holístico. De esta forma, para conseguir un enfoque holístico, es necesario conocer que hay escrito en la literatura científica del ámbito social hasta ahora sobre el envejecimiento activo y saludable, para poder empezar a trazar líneas de actuación desde las instituciones y las políticas sociales. En este presente artículo, se realizó una revisión bibliográfica sistemática en las bases de datos Scopus, Social Servicie Abstract y Dialnet. Tras una serie de descartes, en total se analizaron 77 artículos. Los resultados muestran la importancia de promover un envejecimiento activo y saludable desde las instituciones y políticas sociales. Puesto que no todas las personas pueden envejecer de la misma forma, puesto que las desigualdades sociales y los entornos no amigables con las personas mayores, crean barreras y problemas añadidos para que puedan tener una vejez activa y saludable.
A retrospective observational study to assess the maternal and neonatal outcomes with instrumental delivery in tertiary care hospital
Authors: Nayak Kavitha D.
Published: July 2024

Background: In modern obstetrics, the number of vaginal deliveries is reducing, and instrumental delivery are still reduced. This could be due to need for obstetrician skill for instrumental delivery, increased perineal tears or foetal injuries. The objective of this study was to assess the maternal and neonatal outcomes with instrumental delivery.
Methods: This is a retrospective observational study conducted in tertiary care hospital from January 2023 to December 2023. In this study, 31 cases of forceps delivery and 15 cases of vacuum were studied for maternal and neonatal outcomes.
Results: The total number of deliveries were 2693 and vaginal deliveries were 999 and instrumental deliveries were 46. It was observed that most patients (86.9%) requiring instruments in the second stage were primigravida. The most common indication for instrumental delivery is both fetal distress and poor maternal bearing down efforts. The maternal complications were more with forceps and included extension of episiotomy in 5 cases, third degree perineal tear in 6 cases, 2 cases of hematoma- one case of broad ligament hematoma and 2 patients required blood transfusion. The neonatal complications were more with forceps. However, the outcomes were favourable. We did not have any case of HIE stage 3, no baby required intubation. 3 babies with forceps had poor Apgar at birth and HIE stage 1.
Conclusions: Instrumental delivery is relatively a safe and good option provided all the criteria are met. With proper technique, we can reduce the maternal complications as well.
The myriad presentations of peripartum cardiomyopathy
Authors: Banerjee Yajnaseni , Tilve Arundhati
Published: July 2024

Peripartum cardiomyopathy (PPCM) is an idiopathic, non-ischemic systolic type of heart failure which can present anytime from the last month of pregnancy till the end of 5th month post-partum.  The incidence of PPCM in the Indian population is 1:1340 with 60% of the cases occurring post-partum. PPCM has a mortality rate of 11.7% with unpredictable sequelae ranging from worsening heart failure, cardiogenic shock, development of arrythmias to complete recovery and recurrence in subsequent pregnancies. With an idiopathic aetiology with multiple theories, PPCM remains a diagnosis of exclusion, demanding a high index of suspicion and surveillance in pregnant women. The management involves a multidisciplinary approach involving the obstetrician, cardiologist and at times the anaesthesiologist and includes various drugs like beta- blockers, diuretics, digoxin, bromocriptine. In severe cases, maternal circulatory support may also be needed. We present three cases of PPCM diagnosed in the antepartum, intrapartum and immediate post-partum periods respectively. Out of 3 patients, one delivered vaginally and two underwent emergency caesarean sections. All of patients went home post-delivery with good outcomes and were doing well after 4 weeks of delivery.
A rare case report of uterine rupture in a case of suspected septic abortion
Authors: Kashi Ashwini , R. Sheela S. , S. Harshitha
Published: July 2024

There was a progressive rise in the rate of caesarean sections globally from 17.2% to 21.5% from 2017 to 2021. Caesarean sections have an improved feto-maternal outcome but come with a set of challenges. A second-trimester abortion in a previously scarred uterus is one of them. The incidence of uterine rupture is about 3.8–4.3% in a scarred uterus, which is much higher than in an unscarred uterus. Mifepristone 200 mg orally followed by misoprostol 800 mcg vaginally within 24–48 hours has been proven to be an effective method for medical abortion, but its safety in a previously scarred uterus has not been fully established. A 27-year-old P2L2A1 with two previous caesarean sections at 19 weeks of gestation was referred to our tertiary care center with bleeding per vagina following consumption of medical termination of pregnancy (MTP) pills, followed by dilatation and curettage outside. She was pale, and tachycardia was noted. Septic abortion was suspected due to repeated bouts of fever, raised total counts, and starting on higher antibiotics. Due to persistent tachycardia and computed tomography (CT) findings, she was subjected to exploratory laparotomy, and a uterine rupture was confirmed. She underwent an obstetric hysterectomy as a lifesaving procedure. Second-trimester abortions with misoprostol in a previously scarred uterus require a high index of suspicion and close monitoring. Detecting life-threatening complications early in at-risk patients plays a crucial role in uterine preservation. There is scope for research to incorporate methods like Foley's induction in these cases. The clinical picture of a ruptured uterus can be initially non-specific, delaying the diagnosis. Surgery depends on the extent of the rupture, maternal hemodynamic status, and family completion. It is challenging to rule out uterine rupture when there is a similar presentation as septic abortion, so ultrasound is the first investigation of choice in the diagnosis of uterine rupture, whereas CT abdomen and pelvis are confirmatory.
Effect of obesity in pregnancy: implications for maternal and fetal health
Authors: Bajaj Gaurav , Davu Gayathri
Published: July 2024

Obesity during pregnancy poses noteworthy threats to maternal and fetal health. This investigation looks to probe maternal obesity’s implications on pregnancy outcomes and neonatal health. This study employed a qualitative methodology utilizing secondary data analysis of recent literature to explore the associations between maternal obesity and pregnancy outcomes. Secondary data from 2017 to 2024 were gathered from peer-reviewed journals, databases, and reports published focusing on clinical characteristics and health parameters related to maternal obesity. Only studies providing detailed information on these factors were included. Clinical characteristics such as age distribution, gravidity, parity, and childhood obesity background significantly influenced pregnancy outcomes among obese women. A significant portion of the pregnant women with obesity, over half, were within the age range of 25-30 years, and a notable number had experienced obesity during their childhood. Additionally, obesity during pregnancy significantly impacted various health parameters compared to normal weight, including prepregnant BMI, maternal weight, and incidence of chronic conditions such as hypertension. Maternal obesity correlated strongly with adverse pregnancy outcomes, particularly preeclampsia and rectovaginal group B streptococcus infection. Similarly, adverse neonatal health outcomes were significantly associated with maternal obesity, including fetal macrosomia and neonatal intensive care unit (NICU) admission. Maternal obesity is linked with adverse pregnancy and neonatal outcomes, highlighting the prominence of managing maternal weight to boost maternal and fetal health. These discoveries underscore the necessity for targeted interventions and management strategies to mitigate the risks linked with obesity during pregnancy.

Authors: Quake Sharmaine Yen Ling , Garg Dharmendra , Jha Madan
Published: July 2024

Background: Pelvic exenteration (PE) is radical surgery which offers prospect of cure for patients with locally advanced pelvic malignancy.
Methods: This is a retrospective cohort study evaluating patient outcomes over six-year period at James Cook University Hospital, a tertiary center in United Kingdom. Primary outcome measures included short-term (90 days) mortality and morbidity. Secondary outcome measures were survival and recurrence. Data was analysed by descriptive statistics and Kaplan-Meier curve used for survival estimation.
Results: Out of 68 patients who underwent PE, 88% (n=61) was for primary locally advanced cancer and 10% (n=7) for recurrent cancer. The 31% (n=21) exenterations were for rectal cancer, 68% (n=46) for gynaecological cancer and 1% (n=1) for bladder cancer. Complete (R0) resection was achieved in 86% rectal exenteration versus 68% in gynaecological exenteration (p=0.1459). The overall 90-day mortality rate was 2.9% (n=2). The 19.1% developed major complications (Clavien-Dindo grades 3a-4). The estimated mean overall survival was 55 months (95% CI, 41-71) for rectal versus 44 months (95% CI, 35-53) for gynaecological (p=0.076). At a median follow-up of 19 months, the local and distal recurrence rate for rectal patients after PE was 4.7% and 14.3% respectively. The 41.3% of gynaecological patients developed recurrence and/ or progression of disease.
Conclusions: PE for rectal and gynaecological cancers has low short-term mortality but is associated with high risks of overall complications, most of which were Clavien-Dindo grades <3. The higher recurrence rate observed in the gynaecological cohort is in keeping with the varying intent of the surgery.

Fragmentation as a Generational Strategy
Authors: Afanasov N.B.
Published: July 2024

The article represents the author's reflection on the key features of the philosophical generation that was formed in the Russian-speaking space in the 10s of the 20th century. The author believes that a relevant theoretical lens for considering the specifics that distinguish young people who began their journey in philosophy during these years could be an appeal to the sociological typology of generations. According to the authoritative sociologist Vadim Radaev, the designated philosophical generation belongs to the “millennials.” The key characteristics that distinguish these young people include isolation, passion for gadgets and everyday digitalization, lack of desire to build a career, and inability to integrate into large hierarchical structures.

The Common Law and the General Court in Crete in the Hellenistic Period
Authors: Sizov Sergey K. ,   Professor of the National Research Lobachevsky State University of Nizhny Novgorod
Published: July 2024

Certain evidence demonstrates that in the League of Cretans in the 3rd and 2nd centuries BCE, there was a Code (diagramma) — the only known example of a set of rules of tort and procedural law that was in force on the territory of the entire federation of Greek poleis. The Code contained rules for calculating monetary compensation for an offense, and also regulated the procedure for conducting a trial regarding a delict committed by a citizen of one Cretan city against a citizen of another, or against a foreigner. To consider such cases, a “general court” (koinodikion) was created in Crete, which apparently consisted of representatives of different poleis. The League of Cretans, thus, sought to ensure that conflicts between citizens of different communities of Crete were settled in a uniform and civilized way and would not undermine the unity and stability of the entire federation.

The annual increase in the number of bankruptcy cases is followed by an increase in the number of arbitration managers, which is reflected in the increased burden on them to implement the responsibilities assigned by the Federal Law ‘On Insolvency (Bankruptcy)’. For the proper execution of the powers of the arbitration manager in a bankruptcy case, there is a need to involve persons who ensure his activities. However, the involvement of such persons entails the need to transfer certain powers to them. In this article, the authors analyze the legislative limits of the permissibility of transferring the powers of arbitration managers in a bankruptcy case.
On the Correlation between the State (Political) Regime and Other Elements of the State Form
Authors: Kondrashev Andrey A. ,   Professor, Head of the Department of Constitutional
Published: July 2024

The article is devoted to doctrinal issues of the relationship between the state (political) regime and other elements of the form of the state: the form of government and the form of government. The author comes to the conclusion that, despite the mutual influence of all elements of the form of the state, the determining factor for the characteristics of a particular state is still the state (political) regime. It is the methods of power, the current political practice that determine the specific objective and subjective varieties of the corresponding forms of government and government structure, determined by various reasons. It can be stated that the state regime makes it possible to implement the legal characteristics of the form of government in different ways, taking into account the real situation of government bodies of different branches of government in a particular period, as well as the implementation of the actual form of government in the corresponding state.

Relevant Problems of Bringing to the Administrative Liability for Violation of Legal Requirements for Distribution of Internet Advertising
Authors: Kanunnikova Natalya G. ,   Head of the Department of State, Civil and Legal Disciplines of the North Caucasian Institute of Advanced Training (Branch) of the Krasnodar University
Published: July 2024

Amendments to administrative laws that stipulate the liability for violation of requirements for distribution of Internet advertising entered into force on September 1, 2023. These requirements stipulate obligatory labeling of advertising materials and provision of data to the Unified Internet Advertising Register. The presented article analyzes these administrative law novelties. The author highlights that labeling of Internet advertising is a complex and multi-aspect process, where distribution of illegal conduct is unacceptable. In this context, introduction of the administrative liability for violation of legal requirements for distribution of Internet advertising is viewed as timely and justified. Based on the conducted research, the author brings forward a proposal for supplementing sanctions of Part 15-17, Art. 14.3 of the Administrative Offense Code of the Russian Federation with punishment in the form of a warning for comprehensive assurance of adequacy of legal consequences for the above named offenses taking into account special aspects of functioning of advertising distributors and providers.
Les territoires de l’hétérodoxie dans le second tome de la Cosmographie universelle (1575)
Authors: Viaud Alicia , Catel Thibault
Published: July 2024

Au sein du second tome de la Cosmographie (1575), qui s’intéresse aux espaces extra-européens, savoirs géographiques et polémique religieuse s’entrecroisent. Belleforest réélabore ses sources, en particulier la Cosmographia de Münster, pour les placer au service de la défense d’un catholicisme intransigeant. Les territoires de l’hétérodoxie forment autant de mondes à l’envers, où le mal se donne à voir sous ses multiples visages. Décrit comme un péril surgi au coeur même de la chrétienté, la figure du protestant se surimprime de manière récurrente à celle de l’étranger idolâtre, l’hérésie du premier surpassant toujours celle du second. Au sujet de la religion des Turcs, Belleforest s’attache à la description des moeurs plutôt qu’à la théologie et aux conséquences politiques de la différence religieuse. Considérée comme une forme dégénérée du christianisme, l’hérésie turque permet de blâmer l’ensemble des manifestations de l’hétérodoxie et d’exhorter le pouvoir royal à veiller à la sauvegarde de l’orthodoxie.

Evaluating Ethiopia’s Environmental Strategy: Does it Support Green Growth?
Authors: Mohamed Seid Yimam , Arega Tiruwor , Occhiali Giovanni
Published: July 2024

Ethiopia has been pursuing a manufacturing-led development strategy since the early 2000s, achieving substantial growth and poverty reduction for over a decade. However, little attention has been paid to whether these results were achieved at the expense of environmental sustainability. Relying on the review of promulgated environmental policies and on 22 in depth interviews with public and private stakeholders, this study aims to assess whether the existing command and-control approach to environmental management is delivering on its promises, and whether there is scope for a wider deployment of environmental taxes. Our analysis demonstrates that, despite the implementation of a variety of policies since the late 1990s, environmental management in Ethiopia is substantially ineffective. This is due to a combination of institutional instability and a lack of technical and human resources in the main agency tasked to protect the environment, and to the low political priority of environmental protection, seen as an unaffordable luxury when pursuing rapid economic growth. In this context, whether a switch to a market-based approach to environmental management would improve the situation seems doubtful, as any new instrument would be ineffective as long as there is a lack of political will to enforce environmental protection by capacitating the agencies mandated to this task.
