Although endometrial cancer is usually diagnosed in early stages of the disease due to the frequent association of worrisome symptoms such as postmenopausal bleeding, in certain cases the patients are diagnosed when metastatic lesions are already present. In such cases, a multidisciplinary approach is needed in order to achieve a maximum benefit in terms of survival. The aim of the current paper is to report a 62 year old patient diagnosed with endometrial cancer with bone and pulmonary metastases in whom a complex oncological and surgical therapeutic strategy was performed with good results.

Ovarian cancer is characterized through a high capacity of spread via multiple pathways such as peritoneal, hematogenous or lymphatic route. Therefore, upper abdominal involvement might be encountered; in such cases extended visceral resections might be needed in order to achieve radical cytoreductive surgery. The aim of the current paper is to report the cases of three patients diagnosed with extended upper abdominal lesions and in which distal gastrectomy was successfully associated. Postoperatively a single case developed a postoperative leak which was successfully treated in a conservative manner. In all cases the histopathological studies demonstrated the presence of tumoral involvement of the gastric wall. In conclusion, gastrectomy can be safely associated as part of debulking surgery for advanced stage ovarian cancer in order to increase the chances to obtain long term survival.

Endometriosis represents a debilitating disease affecting women at fertile age which is associated with severe symptoms such as chronic pelvic pain, dysmenorrhea, dyspareunia and infertility. The pathogenesis of this disease is not fully understood so far, multiple theories being proposed. However, more recently, attention was focused on identifying the role of genetic factors in endometriosis development. In the current paper we aimed to review the most important theories regarding pathogenesis. Furthermore we discuss the genetic factors regarding this illness as well as other genes that are suspected to be culprits in leading to this pathology.
Sestrin2 Regulates Beneficial β3-Adrenergic Receptor-Mediated Effects Observed in Inguinal White Adipose Tissue and Soleus Muscle

Published: June 2022

Sestrin2, a well-known adenosine monophosphate-activated protein kinase (AMPK) regulator, plays a protective role against metabolic stress. The β3-adrenergic receptor (β3AR) induces fat browning and inhibits muscle atrophy in an AMPK-dependent manner. However, no prior research has examined the relationship of sestrin2 with β3AR in body composition changes. In this study, CL 316,243 (CL), a β3AR agonist, was administered to wild-type and sestrin2-knockout (KO) mice for 2 weeks, and fat and muscle tissues were harvested. CL induced AMPK phosphorylation, expression of brown-fat markers, and mitochondrial biogenesis, which resulted in the reduction of lipid droplet size in inguinal white adipose tissue (iWAT). These effects were not observed in sestrin2-KO mice. In CL-treated soleus muscle, sestrin2-KO was related to decreased myogenic gene expression and increased levels of muscle atrophy-related molecules. Our results suggest that sestrin2 is associated with beneficial β3AR-mediated changes in body composition, especially in iWAT and in the soleus.

Published: June 2022

Background: Current evidence support that the gut microbiota plays a potential role in obesity. Bariatric surgery can reduce excess weight and decrease the risk of life-threatening weight-related health problems and may also influence gut microbiota. In this study, we aimed to investigate the changes in gut microbiota before and after bariatric surgery and evaluate the association of the gut microbial shift and altered body mass index (BMI) after bariatric surgery.Methods: Between January 2019 and July 2020, stools from 58 patients scheduled for bariatric surgery were collected. Six months after bariatric surgery, stools from 22 of these patients were re-collected, and the changes in gut microbiota before and after bariatric surgery were evaluated. In addition, the differences in gut microbiota between patients with severe obesity (BMI >35 kg/m2, n=42) and healthy volunteers with normal BMI (18.8 to 22.8 kg/m2, n=41) were investigated.Results: The gut microbiota of patients who underwent bariatric surgery showed increased α-diversity and differed β-diversity compared with those before surgery. Interestingly, Blautia was decreased and Bacteriodes was increased at the genus level after bariatric surgery. Further, the Blautia/Bacteroides ratio showed a positive correlation with BMI. To validate these results, we compared the gut microbiota from severely obese patients with high BMI with those from healthy volunteers and demonstrated that the Blautia/Bacteroides ratio correlated positively with BMI.Conclusion: In the gut microbial analysis of patients who underwent bariatric surgery, we presented that the Blautia/Bacteroides ratio had changed after bariatric surgery and showed a positive correlation with BMI.

A Green Pea Starburst Arising from a Galaxy–Galaxy Merger

Published: June 2022

Green Pea galaxies are low-redshift starburst dwarf galaxies, with properties similar to those of the high-redshift galaxies that reionized the universe. We report the first mapping of the spatial distribution of atomic hydrogen (Hi) in and around a Green Pea, GP J0213+0056 at z = 0.0399, using the Giant Metrewave Radio Telescope (GMRT). Like many Green Peas, GP J0213+0056 shows strong Hi 21 cm emission in single-dish spectroscopy, strong Lyα emission, and a high [Oiii]λ5007 Å/[Oii]λ3727 Å luminosity ratio, O32 ≈ 8.8, consistent with a high leakage of Lyman-continuum radiation. Our GMRT Hi 21 cm images show that the Hi 21 cm emission in the field of GP J0213+0056 arises from an extended broken-ring structure around the Green Pea, with the strongest emission coming from a region between GP J0213+0056 and a companion galaxy lying ≈4.7 kpc away, and little Hi 21 cm emission coming from the Green Pea itself. We find that the merger between GP J0213+0056 and its companion is likely to have triggered the starburst, and led to a disturbed Hi spatial and velocity distribution, which in turn allowed Lyα (and, possibly, Lyman-continuum) emission to escape the Green Pea. Our results suggest that such mergers, and the resulting holes in the Hi distribution, are a natural way to explain the tension between the requirements of cold gas to fuel the starburst and the observed leakage of Lyα and Lyman-continuum emission in Green Pea galaxies and their high-redshift counterparts.

Abstract

Introduction: Selenium (Se) is one of the environmental factors with an essential role in the pathogenesis of autoimmune thyroid disease (ATD). Scarce data is available for the selenium status of the Bulgarian population especially for patients with thyroid disorders.

Aim: To compare the serum selenium (s-Se) concentrations in patients with ATD and healthy controls from Bulgarian population.

Materials and methods: The s-Se concentrations were measured in 105 patients newly diagnosed or untreated for the previous 6 months with ATD (mean age 44±13 years). The patients were divided into three groups: euthyroid autoimmune thyroiditis (AIT) (n=31), hypothyroid AIT (n=33), and hyperthyroid patients with AIT or Graves’ disease (GD) (n=41). The results were compared to s-Se concentrations in 40 age- and sex-matched healthy controls. Determination of s-Se was carried out by inductively coupled plasma mass spectrometry (ICP-MS) after microwave-assisted acid mineralization of the serum samples.

Results: The s-Se concentrations in patients with hyperthyroidism were significantly lower than those in the control group (hyperthyroidism: 69±15.0 µg/L vs. controls: 84±13 µg/L, p<0.001). There was no significant difference in the s-Se concentrations between euthyroid and hypothyroid participants with AIT and healthy controls. The s-Se concentrations in our control individuals were within the range of 53-137 µg/L, reported in literature data on mean serum and plasma levels of European healthy adults.

Conclusions: The mean s-Se concentrations observed in all groups were below or close to the cutoff value of 80 µg/L, considered optimal for the activity of the Se-dependent antioxidant systems.

Abstract

Introduction: The present pilot study evaluates the quality of life of Bulgarian patients after a conventional hernia operation in which light or standard polypropylene hernia meshes were used.

Materials and methods: Sixty-eight patients planned for recovery of primary or recurrent open hernia with implanted standard or lightweight polypropylene meshes were included in the study. Patients’ data were collected prospectively for a 5-month period (October 2017 - February 2018) on the basis of the case histories. The patients were interviewed using the EQ5D questionnaire and a visual analogue scale. Follow-up of each patient’s results was performed up to a year after surgery.

Results: Three months after the operation, the patients reported only the presence of pain. On average, 24.5% of patients experienced mild pain and 20.3% - severe pain. In the standard mesh group, on average, the mild pain was 7.69%, swelling 3.84%, and foreign body sensation - 15.38% one year after the surgery. In the light mesh group the reported mild pain was 6.69%, pulling without pain - 13.33%, and foreign body sensation - 6.69%. There was no statistically significant difference in the pain level according to the used mesh, but in the group with implanted standard meshes, the reported problems prevailed. At the end of the survey period, the average score was 84.39±13.67.

Conclusions: Hernia operation reduces pain 1 year after the procedure. The intensity of chronic pain one year after the surgery is relatively similar for both light and standard meshes in conventional inguinal hernia repair. The differences in the overall quality of life are insignificant in the long run. An individualized choice, based on the patients’ characteristics and safety of meshes, should be done by the healthcare specialists.
Discovery of a new phragmotic species of the ant genus Carebara Westwood, 1840 (Hymenoptera, Formicidae) from Cambodia
Authors: Hosoishi Shingo , Yamane Seiki , Sokh Heng
Published: June 2022

Several phragmotic species in the ant genus Carebara Westwood, 1840 with a cephalic shield are known from the Old World, but species with an anteriorly truncated head seem to be unknown until now. A new species, resembling the phragmotic workers of the ant genus Colobopsis, is here described as Carebara colobopsis Hosoishi & Yamane, sp. nov., based on major and minor worker found in Cambodia. This new species is similar to Carebara acutispina (Xu) and C. obtusidenta (Xu) in some important characters, but distinguished from the latter two by distinct metanotum and deep groove in front of metanotal disc in the major worker, and longer head and deep metanotal groove in the minor worker. This is the first confirmed record of a truncated phragmotic head in the major worker of the genus Carebara. We propose the Carebara acutispina species group to include all the three species, present a diagnosis of this group, and provide a key to species based on the major and minor worker castes.

Clarification of the status of Paraferreola Šustera, 1912 as an available genus name in Pompilidae, and the identity of Sphex ursus Fabricius, 1793 in Mutillidae (Hymenoptera)
Authors: Brothers Denis J. , Lelej Arkady S. , Williams Kevin A.
Published: June 2022

The usage of Paraferreola Šustera, 1912 since its proposal as a genus of spider wasps, but based on a misidentified type species (Sphex ursus Fabricius, 1793, actually a species of Mutillidae), shows that it continues to be applied (although infrequently) in Pompilidae, despite the proposal of new names (Eoferreola Arnold, 1935 and Tea Pate, 1946) for the equivalent generic concept. Application of Article 70.3.2 of the fourth edition of the International Code of Zoological Nomenclature permits correction of the erroneous type species designation to that originally intended (Sphex rhombica Christ, 1791), and thus the maintenance of Paraferreola as a valid genus in Pompilidae. Examination of the holotype specimen of Sphex ursus has shown it to be a senior synonym of Mutilla vesta Cresson, 1865 and its junior synonyms, for which the valid name must thus be Dasymutilla ursus (Fabricius, 1793), comb. nov.

Published: June 2022

The genus Motacilla belongs to Motacillidae (Passeriformes), where mitochondrial features are poorly understood and phylogeny is controversial. Whole mitochondrial genome (mitogenome) data and large taxon sampling are considered to be ideal strategies to obtain this information. We generated four complete mitogenomes of M. flava, M. cinerea, M. alba and Dendronanthus indicus, and made comparative analyses of Motacilla species combined with mitogenome data from GenBank, and then reconstructed phylogenetic trees based on 37 mitochondrial genes. The mitogenomes of four mitogenome sequences exhibited the same gene order observed in most Passeriformes species. Comparative analyses were performed among all six sampled Motacilla mitogenomes. The complete mitogenomes showed A-skew and C-skew. Most protein-coding genes (PCGs) start with an ATG codon and terminate with a TAA codon. The secondary structures of RNAs were similar among Motacilla and Dendronanthus. All tRNAs except for trnS(agy) could be folded into classic clover-leaf structures. Three domains and several conserved boxes were detected. Phylogenetic analysis of 90 mitogenomes of Passeriformes using maximum likelihood (ML) and Bayesian inference (BI) revealed that Motacilla was a monophyletic group. Among Motacilla species, M. flava and M. tschutschensis showed closer relationships, and M. cinerea was located in a basal position within Motacilla. These data provide important information for better understanding the mitogenomic characteristics and phylogeny of Motacilla.

Comportement des ménages brésiliens face à la COVID-19
Authors: Phélinas Pascale , Ciriez Camille , Ciriez Camille
Published: June 2022

L’objectif de ce travail est d’explorer les perceptions et attitudes des Brésiliens face à l’épidémie de COVID-19, et de déterminer les facteurs de nature à expliquer ce qui conduit les individus à respecter les mesures de distanciation sociale, et les gestes barrières indispensables au contrôle de la propagation du coronavirus. Les résultats sont fondés sur trois vagues d’enquête menées en 2020 auprès d’un échantillon représentatif de ménages. Dans un contexte marqué par les prises de position répétées du président brésilien contre les politiques de prévention dans les médias et réseaux sociaux, nous montrons que la confiance des populations envers les autorités publiques (politiques, médicales, scientifiques, religieuses etc.), et notamment envers le président de la République, a joué un rôle essentiel dans l’adhésion des populations aux mesures destinées à maîtriser la propagation du virus. Le respect des mesures de distanciation sociale et des gestes barrières est plus difficile pour les Brésiliens qui ont confiance dans leur président. Ce résultat confirme l’influence cruciale du leadership au plus haut niveau du gouvernement sur les comportements, et consolide les résultats d’études menées dans d’autres pays.
L’Europe puissance relancée ?
Authors: Warlouzet Laurent
Published: June 2022

« L’Europe a créé un marché, elle n’a pas créé une puissance », se lamentait le journaliste Jean-Jacques Servan-Schreiber dans son célèbre opus Le défi américain (Denoël, 1967). Pourtant, l’Europe puissance semble relancée tant par la guerre en Ukraine que par la présidence française de l’Union européenne au premier semestre 2022. La « puissance » constitue, aux côtés de la « relance » et de l’« appartenance », l’une des trois priorités de cette présidence. À l’heure de son achèvement, un premier bilan peut en être dressé sous le prisme de l’Europe puissance.

Cet écrit propose d’identifier la place qu’occupe la stratégie thérapeutique dans ma pratique de la Gestalt-thérapie et notamment la manière dont elle peut cohabiter avec une posture qui privilégie la présence ici-maintenant, l’attention au champ organisme/environnement, la suspension du savoir et l’absence de projet. Une première situation clinique permet d’explorer la manière dont la stratégie thérapeutique s’élabore et évolue avec le temps. Une seconde se propose d’illustrer comment elle prend place ou pas au sein des séances.

Published: June 2022

Partant du constat d’une faible efficacité de l’enseignement proposé aux publics migrants à travers les dispositifs de l’Office français de l’immigration et de l’intégration (OFII) pour les niveaux « alpha à A1 », l’étude repose sur un dispositif expérimental MigraFLE. Ce dispositif a pour objectif de proposer un accompagnement global (linguistique, culturel, psychologique, social et professionnel). Les cours de français sont basés sur une approche interculturelle à laquelle s’est articulée une démarche spécifique de l’oral vers l’écrit. Les premiers résultats montrent que, dans le cadre de cet accompagnement, un programme de 150 heures de cours peut suffire à amener les apprenants de faible niveau vers l’obtention du DILF et DELF A1.
Qualitative analysis of a fuzzy Volterra-Fredholm integrodifferential equation with an Atangana-Baleanu fractional derivative

Published: June 2022

The point of this work was to analyze and investigate the sufficient conditions of the existence and uniqueness of solutions for the nonlinear fuzzy fractional Volterra Fredholm integro-differential equation in the frame of the Atangana-Baleanu-Caputo fractional derivative methodology. To begin with, we give the parametric interval form of the Atangana-Baleanu-Caputo fractional derivative on fuzzy set-valued functions. Then, by employing Schauder's and Banach's fixed point procedures, we examine the existence and uniqueness of solutions for fuzzy fractional Volterra Fredholm integro-differential equation with the Atangana-Baleanu-Caputo fractional operator. It turns out that the last interval model is a combined arrangement of nonlinear equations. In addition, we consider results by applying the Adams Bashforth fractional technique and present two examples that have been numerically solved using graphs.
Green closed-loop supply chain optimization strategy considering CER and incentive-compatibility theory under uncertainty
Authors: Guo Jianquan , Wang Guanlan , Gen Mitsuo
Published: June 2022

Under the uncertain market demand and quality level, a total profit model of green closed-loop supply chain system (GCL-SCS) considering corporate environmental responsibility (CER) and government differential weight subsidy (GDWS) is constructed. Based on incentive-compatibility theory, the optimal subsidy allocation policy and green investment level were explored. Fuzzy chance-constrained programming (FCCP) is used to clarify the uncertainty factors of this model; while genetic algorithm (GA) and CPLEX are used to find and compare a calculating example's approximate optimal solution about this model. The main calculating results indicate that: (1) Enterprises can make optimal recycling, production and sales strategies according to different potential demand; (2) Without government subsidy, enterprises' higher green investment level will reduce their average gross profit, increase the quality level of recycled products and decrease the recycling rate, hence reduce their environmental protection willingness; (3) Based on incentive-compatibility theory, when government subsidy weight is set as 0.34~0.41 for consumers, enterprises' higher green investment level will enhance their average gross profit, reduce the quality level of recycled products and increase the recycling rate, which will improve their environmental protection willingness; (4) Under uncertain environment, the combination of reasonable government subsidy policy and enterprises green investment can make up for the defect of enterprises green investment alone, maximize utilities of government and enterprises, and optimize the green closed loop supply chain.
Sources écrites et topographie chrétienne de Daphné, quelques remarques
Authors: Alpi Frédéric
Published: June 2022

Le témoignage de Jean Moschos, vers 605, sur l’existence d’un martyrium de sainte Euphémie à Daphné, puis la mention de celui-ci dans les actes des conciles de Latran (649) et de Constantinople (680), se trouvent en contradiction avec les sources parallèles (Évagre le Scholastique ou la Vita Marthae), comme avec la logique calendaire et ecclésiologique du patriarcat de Sévère d’Antioche (512-518) auquel est rapporté ce sanctuaire. Il semble bien qu’il s’agisse ici d’un montage polémique : la sainte patronne du dogme chalcédonien se voit substituée au martyr local Romanos, assez fortuitement associé, pour sa part, à l’élévation de Sévère sur le trône patriarcal en 512. Pour des raisons de piété personnelle, ce dernier introduisit également à Daphné, en 513, le culte de saint Léonce qui devint alors, conjointement avec Romanos, l’intercesseur privilégié du patriarche.
Revisiter les archives des missions franco-américaines de Princeton : le cas de la résidence de Yakto près d’Antioche
Authors: Morvillez Éric
Published: June 2022

En 1932, on découvrait par hasard à Yakto, près d’Antioche, la mosaïque de Megalopsychia, aujourd’hui conservée au musée archéologique du Hatay. Les fouilles entreprises permirent la mise au jour d’une imposante résidence. Depuis les publications de Jean Lassus en 1934 et 1938, l’édifice est resté à part dans l’univers de l’architecture domestique. Le présent article se propose de le relire à la lumière des archives photographiques, mais aussi des dessins et aquarelles des pavements de mosaïque et d’opus sectile, pour la plupart inédits, conservés dans les archives de la mission, à l’université de Princeton (Department of Art and Archaeology, Visual Resources Collection) : 237 documents photographiques et dessins, sans compter les carnets de fouilles. Si le caractère résidentiel de l’ensemble ne semble plus discutable, son fonctionnement en revanche continue de susciter bien des interrogations. Les espaces, répartis en trois secteurs, ont pu compter jusqu’à trois niveaux de pavements successifs entre le ive et le vie siècle, et d’après les comparaisons, toute une série de sols doit être placée entre la fin du ive et les premières décennies du ve siècle. Les cours pavées de mosaïques figurées ont dû jouer un rôle important dans l’ensemble. Il semble enfin possible, en tenant compte des niveaux sous-jacents et en observant les agencements des secteurs, de penser que l’édifice tardif serait né du remaniement de plusieurs bâtiments résidentiels antérieurs.
De la mosaïque au dictionnaire topographique. Les légendes de la bordure topographique de la mosaïque de Megalopsychia
Authors: Saliou Catherine
Published: June 2022

La célèbre bordure topographique de la mosaïque dite « de Megalopsychia » mise au jour à Yakto (Daphné) est trop souvent utilisée à des fins d’illustration, sans prise en compte des difficultés d’interprétation qu’elle soulève et sans véritable réflexion sur son apport documentaire. L’étude de ses légendes met en évidence les ambiguïtés du vocabulaire architectural. Sept édifices de Daphné ne sont connus que par cette mosaïque. Il s’agit pour certains d’édifices assez récents à l’époque où elle fut posée. Leur présence témoigne du dynamisme de l’agglomération dans l’Antiquité tardive. La mosaïque présente donc l’image d’une ville en mouvement, non seulement parce que le paysage urbain est animé de personnages en déplacement, mais aussi parce qu’elle nous permet de saisir un instantané d’un espace urbain en train de changer.

In this article, we present a new figural graffito from the temple of Bel at Palmyra and place it in context with two recently published examples from Tomb no. 173. They may constitute corroborating figurative visual representations for a segment of the Palmyrene trading cycle that has hitherto rested on epigraphic, ethnographic or other historical indirect evidence.
HyLaw or Hydrogen Law
Authors: Norouzi Nima
Published: June 2022

In recent years, hydrogen technology has been at the forefront of environmental discussions to meet increasingly tough climate protection goals and particularly low emissions targets in the transportation sector. Like any major change, a transition to hydrogen energy faced challenges in many countries, which caused several problems in the growth of the hydrogen share of the total energy supply portfolio. In 2018, Hydrogen Law (Hylaw) was introduced, which removes the legal barriers to the deployment of fuel cells and hydrogen applications. It is a flagship project aimed at boosting the market uptake of hydrogen and fuel cell technologies providing market developers with a clear view of the applicable regulations while calling policymakers' attention to legal barriers to be removed. This chapter introduces a consistent framework for the Hylaw regulations that makes is a clear and precise statement and an interconnection between law and energy management policies.

Green or sustainable chemistry is now recognised as an important scientific subject, and research in this area has led to the creation of cleaner and safer chemical processes, with many new advances occurring each year. Researchers are very interested in unconventional or alternative solvents for chemical synthesis. Chemical solvents make up around 80% of all chemical compounds utilised in a variety of essential chemical processes, notably in the chemical industry. Unfortunately, many of these solvents are volatile organic compounds (VOCs) produced from petrochemicals, which pose a variety of health and environmental hazards. In this chapter, different environmentally benign solvent alternatives have been discussed based on their green matrix in chemical processes.

The storage of electrical energy is an important thing today because it is influenced by the increasing human energy needs. Batteries are one of the energy storage that continues to be explored. Sodium-ion batteries are batteries that are planned to replace lithium-ion batteries. The abundance of sodium elements and their more economical price than lithium are the main attractions. The main constituent components of sodium batteries are anodes and cathodes. Both have a significant influence on the performance of sodium batteries. Currently, several cathodes have been developed but have some challenges especially their instability to air exposure. NaNi0.5Ti0.5O2 is a transition metal oxide-based cathode that has been known to have good structural stability. In this study, NaNi0.5Ti0.5O2 has successfully developed using a combination method of co-precipitation and solid-state. The precipitant is oxalic acid, while the chelating agent is ammonia. The obtained oxalate precursor was sintered in the airstream. Characterization of NaNi0.5Ti0.5O2 is carried out. XRD patterns demonstrate a hexagonal-layered material structure. The material was achieved after the sintering process, according to FTIR analysis. XRF analysis confirmed the composition of the final product in the form of Ni 54.7% and Ti 45.26%. The SEM test showed uniform particles with an average size of 3 microns. Small particle size, which allows greater diffusion of Na ions thereby improving electrochemical performance. This structure characterization result shown that the used method has been succeed. The obtained EIS graph is a semi-circle and slope that shows the process of charge transfer of lithium ions on the surface of the material and electrolyte.

The PEM fuel cell was examined using numerical simulation in varied circumstances. To restore the fuel cell performance, a 3D-based PEMFC model was designed employing COMSOL Multiphysics 5.1. The analysis validity was confirmed using the V-I curves derived from data analysis in varied operational circumstances. The continuity, momentum, species transport and charge equations were used to represent the cell transport phenomenon. The flow of permeable medium in the gas diffusion layer was defined by employing Brinkman equations. V-I curves were obtained using the Butler-Volmer equations. According to findings, the current supply in the cathode catalyst layer achieves an optimum one, functioning as mass transport, ionic and charge transport resistances. It indicates optimum current supply in the cell holds a feature of highest oxygen deprivation on the channel's output side.

Published: June 2022

In the modern construction practice high amounts of fly ash are not accepted by the construction industry due to a slower rate of strength gain at early age. A study has been undertaken to hasten the hydration process by proposed accelerated curing method of high volume fly ash concrete. Large amount of cement (up to 70% by weight) has been replaced by fly ash. The test results of the compressive strength of accelerated cured mixtures gives about (87-100)% strength ratios from itsa28 days compressive strength within one day only. That indicates, the compressive strength at 28 days can be achieved within 1 day only by using proposed accelerated curing. The results of drying shrinkage show that, the drying shrinkage of mixtures under conventional and accelerated curing conditions are comparable and these results add further benefit of this proposed accelerated curing. Key word: accelerated curing, high volume fly ash , curing cycle, drying shrinkage, flow ability.

Published: June 2022

Now- a- days the polymers are frequently used in domestic and industrial purposes. The properties of polymer composites are somewhat inferior and may be improved with the addition of filler and fiber materials. Jute is one of most economical natural fibres and is obtained primarily from plant materials such as cellulose and Lignin. Sisal is a vegetable, natural, fully biodegradable fibre and which has good specific strength and stiffness and is used for making ropes and twines. The banana fibre is the strongest natural fibres and is made from the stem of the banana tree which. exhibits good tensile strength and incredibly durable and bio-degradable. An attempt is made to improve the properties of polymer composites using jute, sisal and banana fibers and addition of 2 % titanium di boride as filler material. The polymer composites were made by hand layup method with epoxy as matrix material. The mechanical properties of fabricated composites such as tensile and impact strength, hardness were evaluated as per ASTM standards. It is found that tensile strength, hardness and impact strength were improved with the addition of fibers and filler material. The micro structural evaluation is also carried out using scanning electron microscope and found that particles were dispersed in the matrix material.

Published: June 2022

Expanded perlite as an aggregate in concrete may make insulating concrete and fire-resistant suitable for roof decks and other purposes. Expanded perlite aggregate (EPA) may be used with gypsum plasters and Portland cement to protect columns, beams, and external applications. Other building uses are chimney linings, under-floor insulation, ceiling tiles, gypsum boards, and roof insulation boards. The primary goal of this research is to learn more about the effects of employing perlite aggregate (EPA) as a partial or complete substitute for sand on various characteristics of expanded perlite concrete (EPC) at 7 and 28 days. Air-dry density, compressive strength, water absorption, flexural strength, and thermal conductivity are all investigated in this research. EPA replacement by volume of sand was used to create five EPC mixes with 0%, 25 %, 50 %, %, and 100%. The effects of introducing 0.5% polypropylene fiber on the characteristics of EPC mixes were investigated. To increase the EPC workability, superplasticizer was utilized, particularly at the higher EPA replacement levels. The test outcomes reveal that the measured mechanical and physical properties of EPC decrease when increasing the EPA content. Thermal insulation of EPC increases with increasing the percentage of perlite aggregate replacement. In addition, using polypropylene fibers in the EPC specimens cause a slight reduction in density, compressive strength, and thermal conductivity compared to unreinforced specimens. Polypropylene fibers significantly increase in modulus of rupture reach 29% at 28 days, and increase in water absorption compared with unreinforced specimens.

The Mechanism of Adsorbents Adsorption Affinity in Relation to Geometric Parameters
Authors: Ntsondwa Sindisiwe , Msomi Velaphi , Basitere Moses
Published: June 2022

In the process of incorporating adsorption with thermal desalination, adsorbents are important because they increase the water vapour uptake rate, and this would yield more desalinated water over a short period. Therefore, they are important and the key parameters in the selection of adsorbent for an adsorption desalination (AD) cycle are thermo-physical properties, surface characteristics and water vapor uptake capacity. The best adsorbent is used as the adsorbent-refrigerant pair and is driven at 50 oC to 85 oC by low-temperature heat sources. When the unsaturated adsorbent is exposed to vapour in the evaporator, the uptake of vapor is accelerated by the high affinity of the water molecules to the silica gel pores. Likewise, when the same adsorbent is heated thermally, the water vapor molecules are removed or desorbed from the adsorbent pores to the cooler surfaces of the condenser tubes, producing high-grade water during the phase.
