Triaxial Tensile Strength Measurement of Compacted Clayey Soils
Authors: Yin Penghai , Vanapalli Sai K. 
Published: June 2023

Abstract
Tensile strength is strongly related to tensile cracking and is a key parameter required in the rational design of earth structures made of compacted clayey soils, such as earth dams, slopes, and embankments. Experimental studies related to the tensile strength of compacted soils that consider the influence of confining pressure is rather limited in the literature. For this reason, a novel experimental technique is developed for the measurement of triaxial tensile strength. Statically compacted soil specimens with a reduced central section are fabricated using a specially designed mold at different initial moisture contents but at the same dry density. The reduced triaxial extension stress path is followed during the test, which induces tensile failure on the reduced central section of the specimen. The triaxial tensile strength increases with an increase in initial matric suction (or decrease in initial degree of saturation) for the investigated range in this study. The variation of triaxial tensile strength with the confining pressure shows a non-monotonic variation, which is attributed to the volumetric deformation prior to failure and the failure mode transition. The test results provide clear evidence of the nonlinearity of the failure criterion, especially when the soil is subjected to tension.
Archeologia e territorio nella letteratura di viaggio sul vicino oriente (XVII-XIX secolo): La scoperta e lo stereotipo
Authors: Di Paolo S. 
Published: June 2023

La letteratura di viaggio fornisce molte informazioni sull’archeologia e la geografia di una particolare regione. Ma, dopo una prima fase nella quale i viaggio vengono organizzati per ragioni politiche e commerciali, in una fase più recente il viaggio nel Vicino Oriente diventa una esperienza personale. Tra il XVI e l’inizio del XX secolo, i viaggiatori europei attraversano la Mesopotamia, la Syria, la Palestina e pubblicano interessanti memorie dei loro tours. Attraverso i diari di viaggio, i resoconti ecc., si possono ottenere molti dati sui siti archeologici e i monumenti antichi, oltre a informazioni geografiche e etnografiche note anche dai testi vicino-orientali e dalla storia dell’arte.Parole chiave: Viaggio, Archeologia, Paesaggio, Scoperta. ResumenLa literatura de viajes proporciona mucha información sobre la arqueología y la geografía de una región en particular. Aunque, tras una primera época en que los viajes se organizaban por motivos políticos y económicos, se pasó a un período en que los viajes al Próximo Oriente venían a ser una experiencia personal. Entre el siglo XVI y comienzos del XX, los viajeros europeos atravesaron Mesopotamia, Siria, Palestina y publicaron interesantes memorias de sus recorridos.

Published: June 2023

Cadmium (II) halides with N,N'-diethylthiourea (detu) ligands at a stoichiometry of 1: 2 tend to form molecular complexes [Cd(detu)2X2] with a distorted tetrahedral geometry at the central atom. Generally, these complex compounds are prepared by the conventional method of reflux for 4 hour. The use of ultrasonic waves for complex synthesis can be an alternative to make the reaction time more efficient and environmentally friendly. The aim of this study was to synthesize and characterize complex compounds from CdBr2 and detu ligands using the ultrasonication method that have not previously reported. The synthesis of complex compounds was carried out by reacting CdBr2 and detu (1:2) in methanol solvent. In the synthesized compounds, a melting point test, electrical conductivity test, Fourier Transform Infrared (FTIR), Scanning Electron Microscope-Energy Dispersive Xray (SEM-EDX), qualitative test of bromide ion and calculation of free energy using Spartan'14 software were carried out for the complex structure prediction. The complex compound resulted has colorless needle crystals with a melting point of 93-94°C. The results of the EDX analysis provide the empirical formula C10H24CdBr2N4S2. The electrical conductivity test data and the bromide ion qualitative test proved that the synthesized complex compound was a molecular complex compound with the molecular formula [Cd(detu)2Br2]. The complex compound has two possible structures, namely a distorted tetrahedral and a square planar. Free energy calculations showed that complex compounds with a distorted tetrahedral structure and a square planar have free energies of -527.5574 kJ/mol and -408.7424 kJ/mol, respectively.

: Systemic lupus erythematosus (SLE) is an autoimmune disorder involving multiple organs. Ocular involvement occurs in both the active and chronic phases. We have conducted a study to illustrate the ocular inflammations associated with SLE leading to visual morbidity. : This prospective, descriptive, hospital-based study was conducted on 75 patients with SLE over 1 year diagnosed by the physician based on the Systemic Lupus Collaborating Clinics (SLICC) criteria. These patients underwent complete ocular examination. Ancillary investigations were done for patients with clinically suspected ocular pathology.: 69% patients had ocular involvement and keratoconjunctivitis sicca (76%) was the most common.42% patients had multiple ocular tissue pathologies. Corneal involvement was noted in 7 patients (14%), comprising of punctate corneal erosions (10%), pannus (2%) and peripheral corneal ulcer (2%), all during the active phase of the disease. 30% patients had episcleritis, diffuse pattern (73%) being the most common and also the presenting sign of SLE in 9% of patients. Retinopathy was seen in 9 patients (18%), vasculitis in 12% being the most common posterior segment association with SLE. The most common cause of defective vision in these patients was steroid induced or complicated cataract (24%). 42% of patients had associated SLE nephropathy.: Simultaneous and multiple forms of ocular inflammation can occur at any stage of SLE, which could compromise the quality of life of the individual. The onset of uveitis is indicative of active status of the disease. A complete ophthalmic evaluation is an important part of management during the active stage and remission.

To compare the efficacy and safety of sutureless glue-free versus suture technique for autogenous conjunctivolimbal grafting in primary pterygium excision. A prospective observational study was conducted in thirty consecutive patients of primary progressive pterygium after taking their informed written consent and ethical clearance in a tertiary eye care centre of Northern India. Patients were randomly divided equally into group “A” and “B” each constituting fifteen patients. Group A patients underwent suture technique and group “B” patients underwent sutureless technique for conjunctivolimbal graft placement. Comparison of both groups was done in terms of intraoperative time, postoperative symptoms and recurrence over a period of one year. Data was compiled and entered into Microsoft Excel software and SPSS version 21.0 was used for data analysis.The mean duration of surgery was 42 min and 30 min in group A and B respectively and this difference was found to be statistically significant (p=0.0001). On 1 postoperative day, pain and foreign‐body sensation was present in 12 patients in group A, while only 1 patient of group B had these symptoms and this difference was statistically significant (p = 0.00014). Postoperative hyperaemia was seen in 8 patients of group A and 6 patients of group B which was statistically insignificant (p = 0.564). Only two patients in group A had conjunctival chemosis while no patients in group B developed chemosis, and the difference was statistically insignificant (p = 0.964). Subconjunctival haemorrhage was seen in 2 patients of Group A and 1 patient of Group B which resolved over a period of 2-3 weeks. Conjunctivolimbal graft was found to be more stable in group A while it was misplaced in 1 patient of group B and the difference was statistically insignificant (p = 1.000). Only 1 patient of group A developed suture related complication i.e suture granuloma. Over a period of 1 year follow up, only 1 patient of group A had recurrence of pterygium.Sutureless glue-free technique is a time saving, cost effective and better surgical modality in comparison to conventional suture technique for autogenous conjunctivolimbal grafting in primary pterygium resection.

Published: June 2023

Endothelial cell loss is a key indicator of the quality of anterior segment surgery like cataract surgery. The amount and integrity of corneal endothelial cells are the two most essential factors determining corneal transparency.Aim of this study was to compare the endothelial cell loss between the superior scleral tunnel incision and the temporal clear corneal incision for phacoemulsification.Prospective observational study. This prospective observational study included 50 patients with grade II and III cataracts undergoing phacoemulsification with a temporal clear corneal incision and 50 patients with a superior scleral tunnel incision. Specular microscopy was used to count ocular endothelial cells before and one month after the surgery.The mean endothelial cell loss was significantly higher with temporal clear corneal incision (14.91% ± 5.13%) in comparison to the superior scleral tunnel incision group (6.58% ± 2.06%). A superior scleral tunnel incision is associated with less postoperative endothelial cell loss as compared to a temporal clear corneal incision and could provide a better visual outcome.

Published: June 2023

Internship is the last year of undergraduate medical training wherein a graduate is exposed to actual patients, conduct varied tasks and acquire skills under supervision of a faculty so that medical student becomes capable of performing clinical skills independently. In India interns have a compulsory 15 days posting in the subject of Ophthalmology. In this study we assessed the clinical skills and knowledge of undergraduate students using a structured questionnaire. A detailed questionnaire based study was conducted which had four parts: (1) clinical skills (2) diagnosis of anterior segment diseases (3) diagnosis of posterior segment diseases and (4) ocular emergencies and sight threatening diseases. Interns were asked to fill this questionnaire before and after completion of 15 days training. : A statistically significant improvement was found i assessment of clinical skills, anterior segment eye diseases and ocular emergencies; whereas assessment of posterior segment diseases showed no statistically significant improvement. The undergraduate teaching program in Ophthalmology seems to be adequate in diagnosis of anterior segment eye diseases and ocular emergencies; though more focus is required in training of diagnosis of posterior segment diseases and certain ocular emergencies. There is a need of change in the structure of training programs of undergraduate students in order to improve their clinical skills and knowledge of appropriate referral after graduation during their independent practice.
Prevalence, risk factors and severity of retinopathy of prematurity in preterm infants in a tertiary care hospital in rural Karnataka
Authors: Shaik Raheemunnisa 
Published: June 2023

Retinopathy of prematurity (ROP) is a condition which is one of the major causes of preventable childhood blindness. ROP may develop in premature new-borns due to avascular or incompletely vascularized retina at birth which are prone to damage. The purpose of this study is to investigate the prevalence of retinopathy of prematurity (ROP), as well as its risk factors and severity, among newborns who were admitted to and screened at a tertiary care facility that serves a rural community.A cross-sectional study was conducted for a period of 1 year. All infants born prematurely who were admitted to the hospital and had a birth weight of less than or equal to 1500 g and/or less than 32 weeks of gestation were included in the study. Additionally, babies born between 1501-2500 grams and/or 33-35 weeks who were at a higher risk were also included. Under aseptic conditions all preterms were screened with RetCam in NICU of a tertiary hospital situated in rural area in Karnataka.224 preterm babies were screened for ROP. No ROP was noted in 185 babies (82.59%), 9 babies had stage 1 (4.02%), 21 babies stage 2 (9.38%), 9 babies had stage 3 ROP (4.02). No infant developed stage 4 and stage 5 ROP. Prevalence of ROP is 17.41% in our study. Low birth weight (LBW), Very low birth weight (VLBW), Respiratory Distress Syndrome and sepsis are found to be clinically significant in this study.In this study, the prevalence of ROP is 17.41%. LBW, VLBW, Respiratory Distress Syndrome and sepsis are found to significant risk factors. Early screening and timely appropriate treatment of ROP can prevent from causing childhood blindness.
