Strength and Durability of Soft Clay Stabilized with Recycled Gypsum (Bassanite)
Authors: Mohammadi Amirhossein , Boroomand Mohammad Reza 
Published: January 2021

Abstract
Every construction has a certain efficient lifetime after which it would need to be repaired or demolished for further reconstruction. This would cause a specific range of waste materials, called construction and demolition (C&D) wastes. Because of the large volume of these bulky waste materials, their utilization in construction and geotechnical projects would be an attractive option in order to recycle and mitigate their volume. Gypsum and its derivatives, as a considerable fraction of C&D wastes, are classified as a group of binding agents in soil stabilization and upgrading its durability against environmental conditions. Bassanite is one of the main gypsum derivatives that is produced through heating gypsum powder at certain conditions. The feasibility of using gypseous wastes as a binding agent was studied by adding different amount of bassanite (0, 5, 10, and 20%) and 5% cement and lime to the clayey soil at different curing conditions (0, 7, 14, and 21 days). Next, the samples were subjected to wetting/drying cycles (0, 1, 2, and 3 cycles), and the effect of these factors on unconfined compressive strength and soil durability were assessed. Results showed that by adding bassanite (along with cement and lime), the unconfined compressive strength of the stabilized soils was considerably increased from 37 kPa to 603 kPa. Another effective factor on the unconfined compressive strength was the soil specimens’ conditions. The wetting/drying cycles over the stabilized samples caused 15–70% decrease in the unconfined compressive strength (according to the soil specimen and number of wetting/drying cycles). It can be concluded that the utilization of gypseous wastes is a proper method to mitigate the amount of landfilled C&D wastes and reusing these materials not only lowers the landfill costs but also significantly decreases the production costs of the materials used in soil stabilization and improvement.

Abstract
In the last few decades, the need for reducing the exploitation of finite sources has led to an increasing use of reclaimed asphalt pavement (RAP) for the construction, maintenance, and rehabilitation of road pavements. During hot mix asphalt (HMA) plant production, RAP can be added at ambient temperature or preheated into special drums. When designing an RAP mixture, it is essential to dose the correct amount of virgin binder according to the percentage of the reactivated aged one. RAP preheating plays a key role in this process, although no reliable methods are available for achieving an accurate estimation. This article presents an innovative digital image-based methodology, named overlapped digital image (OIA) analysis, to better understand the role of reactivated binder on the cracking behavior of HMA-RAP mixtures. A recycled mixture was produced in the laboratory by adding RAP both at room temperature (25°C) and after preheating (150°C) and subsequently tested according to the Superpave IDT at 10°C and 25°C. The tests were combined with the OIA analysis to identify how the strain patterns and the initiation and propagation of fractures developed, according to the reactivation of the aged asphalt binder. The results show important outcomes in terms of cracking behaviors highlighting the important role of RAP preheating for inducing aged binder reactivation.

Published: January 2021

This was study aimed at evaluating and activating the role of electronic management in the International University of Africa and knowing the fields in which electronic management was applied, and to reveal the difficulties that hindered the application of the electronic management system. A sample of the administrative staff and the statistical packages program (SPSS) were used to analyze the results, and the researcher followed the scientific management theory that aimed to reach an optimal work performance. Considering the results, the study showed that the role of electronic management in the university needed to be activated more because of the shortcomings in its activation in the management of personnel affairs, the university administration and student affairs in varying proportions that did not achieve the required level represented in the absence of coordination between its units and the lack of knowledge of workers in this technology and it was applied in all areas of the university, and the existence of difficulties impeding the mechanism of its application. The expectations of this study lie in that it will practically contribute to the development of administrative units in Sudanese universities.

Published: January 2021

ABSTRACTThe northern part of Karawang is a coastal area with mostly mud-sand substrates. This substrate tends to be unstable, so that naturally, this kind of sediment is supported by coastal vegetation that forms coastal ecosystems, such as mangroves; therefore, the importance of mangroves in Karawang coast is definite. Unfotunately the data regarding the condition of mangroves in Karawang Regency is quite insufficient. This information, especially about its existence, is needed as a database for further research and as basis to support government policies on coastal area management. The aim of this research is to provide information about the existence of mangrove in Karawang Regency. The method is by using Normalized Different Vegetation Index (NDVI) calculations on Landsat 8 2018 satellite imagery of Karawang to get the data that reveal the information. We have discovered that the existing of mangroves in Karawang Regency in 2018 is 305,14 Ha. Border coast that is vegetated is only 33.75 km of 77 km long coastline of Karawang. Only less than 5% of the total mangrove protected area in Karawang Regency is detected as mangrove from the total 9.055 Ha of the area.

Published: January 2021

Dans le domaine de la culture, l’impact du patrimoine numérique sur la société est stratégique et constitue la qualité intrinsèque des ressources elles-mêmes. La tendance actuelle incite les institutions GLAM (acronyme anglais pour « Galleries, Libraries, Archives and Museums », en français « Galeries, Bibliothèques, Archives et Musées ») à dépasser la conception du patrimoine comme « Beau » valable en soi, accessible seulement à quelques spécialistes, et au contraire à favoriser des collisions proactives avec les besoins des communautés, leurs perceptions, leurs choix. Ainsi, étant donné que les éléments cruciaux pour un projet de patrimoine digital semblent être les contenus auxquels il donne accès, les fonctionnalités disponibles, et les usagers, il devient essentiel de tenir compte des besoins et attentes de ces derniers, qu’ils soient explicites ou non, pour assurer un service convenable.Cette contribution présente brièvement les principaux problèmes et les possibilités offertes par une structuration des études d’utilisateurs de produits culturels numériques, en se concentrant sur le système, les contenus et les utilisateurs, qui constituent les trois pôles de cette structure interactive.
Comment sortir les textes du musée computationnel ?
Authors: Noille Christine 
Published: January 2021

Numériser des données et documenter les bases participent d’un processus global de patrimonialisation des textes sous forme de données : mais la patrimonialisation passe ici par l’éviction de la textualité. La _distant reading_ n’est que métaphoriquement une lecture car les machines ne lisent pas, au sens littéral.D’où l’urgence, pour les communautés littéraires, fédérées autour des activités de _close reading_, d’évaluer les limites du paradigme éditorial numérique actuel et d’envisager une conversion des humanités numériques à des problématiques de _data-visualization_ susceptibles de répondre à leur attente en matière de lecture augmentée.
Outils hypermédia et temps multidimensionnel du patrimoine
Authors: Martinet Marie-Madeleine 
Published: January 2021

L’article montre comment le numérique donne une vision active du patrimoine, mêlant connaissance du passé et expérience présente. Première possibilité offerte par le numérique : le jeu de rôle historique interactif. Mettant l’utilisateur dans le rôle d’un homme de métier ancien – architecte du XVIII siècle par exemple –, le parcours utilise les fonctionnalités des circuits multimédia, notamment la proposition de choix à chaque étape, pour présenter rétrospectivement les décisions entre plusieurs options prises pour construire un bâtiment, mettant ainsi le patrimoine subsistant sur un fond d’autres options restées irréelles.Les parcours interactifs avec choix peuvent aussi porter sur les représentations du passé : questions d’appariement où l’utilisateur fait correspondre plusieurs images anciennes d’un lieu avec leurs genres picturaux respectifs (comme dessin technique ou peinture imaginative), soulignant ainsi la multiplicité de visions possibles dans la conscience patrimoniale ; et dans les arts contemporains, découverte d’analogies entre les procédés de filtres utilisés pour les images numériques d’un lieu historique, et les effets esthétiques de marbrures dans les représentations anciennes.Le patrimoine recréé par le numérique unit ainsi le patrimoine matériel du passé à la pratique du patrimoine immatériel vécu du savoir-faire.

Le « Fondo Guerra », conservé au Museo Centrale del Risorgimento, a fait l’objet d’un projet ciblé d’informatisation et de numérisation qui a abouti à la constitution du portail www.14-18.it. La numérisation a permis de réunir les documents présents, identifiés et décrits dans les différentes sections. Ce fonds est arrivé au Musée avec pour objectif précis de documenter la Première Guerre mondiale, qui est considérée comme la quatrième Guerre d’Indépendance italienne. L’ensemble des documents recueillis au Musée a été divisé en deux sections: l’« Archivio della guerra » et la « Biblioteca della guerra », qui contient également des notices nécrologiques. Ces deux sections furent divisées en 1935 entre trois institutions différentes : la Biblioteca di storia moderna e contemporanea, le Museo Centrale del Risorgimento et la Biblioteca Universitaria Alessandrina. Aujourd’hui, grâce à ce projet commun de numérisation et d’informatisation, le fonds a été virtuellement réunifié et est accessible en ligne.
Las voces canarias juercan y ajergo: ¿guanchismos o indigenismos hispánicos?
Authors: Morera Pérez Marcial 
Published: January 2021

Frente las interpretaciones etimológicas tradicionales, que, con razones fonéticas y semánticas poco convincentes, consideraban que las voces canarias juercan, juerco, juergo, ajergo, ejergo y jergo ‘vara con pelota de trapo en uno de sus extremos, que se usa para remover el grano en el tostador’ no eran otra cosa que flagrantes guanchismos, para unos, y palabras de origen románico, para otros, se sostiene en este ensayo, con razones formales, semánticas, culturales e históricas mucho más consistentes que las argüidas por guanchólogos, romanistas e hispanistas, que el verdadero origen de estas viejas voces insulares podría encontrarse en la voz bereber aferkan, procedente del aumentativo de la forma latina furca.

Authors: Punjabi Sharda , Devasthali Gauri , Gulati Archana 
Published: January 2021

Background: Anemia is a major public health problem with total prevalence of 30%. It is one of the hematological disorders which can induce retinal changes that are due to retinal hypoxia that leads to nerve fiber layer infarction. Other change includes increased vascular permeability, venous stasis, angiospasm and increased blood viscosity.Methods: This is the cross-sectional study that includes 230 children with age group of 1 to15 years having hemoglobin levels less than 10 gm/dl referred to eye OPD. Ocular examination was done which included-visual acuity, anterior segment, dilated fundus examination.Results: Retinopathy was observed in 95% children of severe anemia and 84% children of moderate anemia. Common findings observed vascular changes, dot blot hemorrhages, flame shaped hemorrhages, sub hyaloids hemorrhages, disc pallor and macular edema.Conclusions: Retinopathy is a frequent finding seen in moderate to severe anemic patients, as the retinal changes were found significantly in maximum patients, it is recommended that all anemic patients particular Hb less than 10 g/dl must undergo routine fundus examinations.

Published: January 2021

Eruptive xanthomas are uncommon with only case reports documented making it difficult to have a prevalence figure. These asymptomatic eruptions are usually a clue to an underlying metabolic disorder with associated cardiovascular risk. Early diagnosis and treatment prevent its associated morbidity and mortality. We present a case series of 2 males (29 and 40 years) and 3 females (14, 28 and 40 years old). They presented with lesions clinically consistent with eruptive xanthomas. Laboratory and histologic investigations revealed dyslipidemia and lipid laden macrophages. They were placed on statins with an improvement of skin lesions and improvement in lipid levels. Dermatologists should be aware of skin lesions as a marker of severe dyslipidemia and its attendant cardiovascular risk. Early treatment leads to resolution of xanthomas and prevention of cardiac related morbidity and mortality.

Authors: Kunwar Brajesh Kumar , Ingle Farah , Ingle Atul , Tulasigeri Chandrasekhar 
Published: January 2021

Pseudoaneurysms are not rare and can occur due to varied reasons including percutaneous vascular access. If left untreated, pseudoaneurysms can be fatal. Here, we have presented a classic case study where a large pseudoaneurysm of left femoral artery with very wide neck was closed using stent graft. A 55 years old male was presented with severe painful large mass in left groin. The mass was soft tissue swelling with severe tenderness and pulsatile in nature. The doppler suggested it to be filled with blood and communicating with femoral artery hence diagnosed as pseudoaneurysm. Attempt was made to compress the neck which was large not clearly defined, hence failed. Multiple interventional and surgical options of closure of pseudoaneurysm was discussed. Patient was taken for stent graft deployment in cath lab. Check angiogram showed nicely flowing femoral artery with no signs of pseudoaneurysm. The patient immediately improved with decrease in pain and swelling.
Laparoscopic cholecystectomy: do upper GI and lower GI surgeons have similar outcomes?
Authors: Chidambaranath Rajesh , Thomas Pradeep F. , Zhen Siu Mei , Reynolds Tim 
Published: January 2021

Background: Laparoscopic cholecystectomy is operation performed on a regular basis, regardless of surgeon’s primary specialty. Common complications include bile duct injury, bile leaks, bleeding, and bowel injury. In Tier 2 Hospitals, upper GI surgeons will manage patients with non-complex OG and HPB disease including laparoscopic cholecystectomy. The AUGSGBI proposed that laparoscopic cholecystectomy (LC) be performed by surgeons trained in upper GI surgery. NICE guidelines recommend similarly. Concentration of surgical expertise and volumes led to lesser conversions and complications. The aim was to compare the complication rates of consecutive patients undergoing laparoscopic cholecystectomy by upper and lower GI consultants in one hospital. Methods: This was a retrospective observational study. We collected 100 consecutive patients from a list of laparoscopic cholecystectomies performed by upper GI surgeons (UGI) and lower GI (LGI) surgeons. All complications were identified from electronic patient records. Complications were recorded according to the Clavien and Dindo system. Median length of stay (LOS) was recorded and compared between the two groups. Results: There was no difference in between groups with respect to sex, age, length of stay or ASA grade, nor a significant difference in complication rates between surgeons of upper and lower GI surgeons. Conclusions: In this study in a selected group, we did not find any difference in procedure related complications between operations conducted by upper GI and lower GI surgeon groups. However, there appeared to be a higher rate of port closure related complication at the umbilicus in operations performed by the lower GI team.

Published: January 2021

Background: Necrotizing fasciitis is highly lethal infection. It can be defined as infection of any layers within the soft tissue compartment (dermis, subcutaneous tissue, superficial fascia, deep fascia or muscle). Early diagnosis and management with identification of co morbidities and treating them brings down the morbidity and mortality rate. To make a full assessment of the cause, all patients require a detailed history, examination and, investigations.Methods: This is a cross sectional comparative study of 50 patients having symptoms of necrotizing fasciitis to be divided into two groups of 25 patients each where one group is having diabetes mellitus and other group without diabetes mellitus.Results: Diabetes mellitus patients have more morbidity and mortality in term of more days of hospital stay, rate of amputations and number of debridements. Early diagnosis and early aggressive debridement is the mainstay of management. Aggressive surgical debridement at initial stages of presentation can halt the clinical process and patient can have better prognosis. In neglected diabetic patient’s debridement alone is not sufficient and amputation may be required in some cases. Conclusions: Early diagnosis and aggressive debridement in necrotizing fasciitis patients results in better outcomes.

Published: January 2021

Background: Acute pancreatitis is a disease for which patients are in large numbers, etiology, clinical presentation and examinations are varied. Disease may be mild or severe, may lead to multi organ failures and death. Most common cause is biliary tract diseases. Other causes are alcohol consumption, post ERCP, trauma, idiopathic and drugs, viral infections, genetic mutations and connective tissue disorders.Methods: This is a prospective observational study conducted at SGT medical college, Budhera, Gurugram, Haryana, from January 2017 to June 2019 in 100 consecutive patients. Data collection included detailed recording of demography of patient, clinical presentation, any history of biliary tract disease, alcohol consumption, trauma, ERCP, comorbidities. Data was also collected about investigations done, treatment, recovery, complications and any intervention. Results: Most of the patients were from age group 41-55 years. Female patients were more than male patients. Etiology was mostly gall stone, alcohol, idiopathic, post ERCP and trauma. Pain, distention abdomen, vomiting, fever and jaundice were presenting features. Serum amylase, serum lipase, USG abdomen and CECT abdomen were diagnostic investigations. Complications included local and systemic. Mortality was 7%. Conclusions: Acute pancreatitis is mild in most of the cases and recovery is good. Severe cases should be meticulously treated as mortality rates are higher. They should be treated in ICU under the guidance of intensivist. Our study results show that patients with severe diseases should be meticulously monitored clinically, biochemically, haemodynamically and radiologically.
