ROAD TRAFFIC LIGHT CONTROL USING IMAGE PROCESSING

The number of vehicles in India is increasing continuously. Indian scenario is the people are buying the vehicle as a symbol of good social status than the requirement. The increase in the number of the vehicles causes the problems of traffic jam along with the hazards to the environment. The sustainable development of any country needs the roads to withstand the heavy vehicles and increasing number continuously. Most of the times the traffic signals are found off or not working properly and hence there is a need of addressing the problem with the help of a smart system for traffic control. Authors have proposed the system for traffic control with the help of the image processing. The system can control the on and off time of the traffic signal as per the requirement of the traffic. The number of vehicles will be analyzed and the control is provided accordingly. https://journalnx.com/journal-article/2015029

Fabrication of polyaniline/TiO2 nanocomposite ammonia vapor sensor

Polyaniline/Titanium dioxide (PANi/TiO2) nanocomposite was fabricated from PANi, prepared by oxidative chemical polymerization and TiO2, synthesized by sol gel method. The PANi/TiO2 thin film sensors were prepared by spin coating technique. PANi/TiO2 nanocomposites were characterized by XRD and SEM. The cross sensitivity of thin film sensor indicate that the sensor exhibit selectivity to ammonia (NH3). The gas sensing measurements were carried out for different concentrations of NH3. The gas sensing study revealed that the response value increases with increasing concentration of NH3. Moreover, as concentration of NH3 increases, the response time decreases while recovery time increases, which can be attributed to the varying adsorption and desorption rates of an ambient gas with increasing concentration.

Adrenal Venous Sampling in Primary Aldosteronism: Single-Centre Experience from Western India

INTRODUCTION: The protocols and criteria used for adrenal venous sampling (AVS) differ across centres. There are no studies from the Indian subcontinent describing AVS-based outcomes in primary aldosteronism (PA). We aim to describe our experience from a single centre. METHODS: Retrospective records from 2018 to 2020 of patients with confirmed PA who underwent AVS were reviewed. Clinical, imaging, AVS data and outcomes (as per PASO criteria) were recorded. AVS was performed by sequential sampling with cosyntropin stimulation with intraprocedural cortisol and cut-off of selectivity \u3e5 and lateralization \u3e4 by a single radiologist. RESULTS: Fifteen patients with median age of 50 years (41-58) and duration of hypertension of 156 (36-204) months were included. Ten had grade 3 hypertension, 13 had hypokalaemia and 3 had hypokalaemic paralysis. On CT scan, eight patients had bilateral adrenal lesions, four had unilateral adenoma and three patients had normal adrenals. AVS was bilaterally successful in all and showed lateralization of disease in 10 patients and was bilateral in the remaining 5 patients. Overall concordance of CT and AVS was 5/15 (33.3%). Among seven patients who underwent surgery, complete clinical success was seen in two and partial clinical success in the remaining five. Complete biochemical success was seen in two and partial in one. There were no major complications. CONCLUSIONS: AVS performed by a single radiologist with defined protocols has a good success rate. AVS has additional value over CT scan in lateralization, especially when CT shows bilateral disease

(2E)-3-(3,4-Dimeth­oxy­phen­yl)-1-(2,5-dimethyl­thio­phen-3-yl)prop-2-en-1-one

The mol­ecule of the title compound, C17H18O3S, is essentially planar: the phenyl and thio­phene rings form a dihedral angle of 2.79 (10)° and they are inclined to the central propenone unit by 6.20 (15) and 4.78 (15)°, respectively. In the crystal, mol­ecules are connected into dimers via pairs of C—H⋯O inter­actions, generating R 2 2(14) motifs. π–π stacking inter­actions between the thio­phene rings also occur, with a centroid–centroid distance of 3.8062 (12) Å

Gonadotropin-Secreting and Thyrotropin-Secreting Pituitary Adenomas: A Single-Center Experience

OBJECTIVE: Data regarding rare FPAs from India, a resource limited setting, are limited. We describe a case series of rare FPAs from a single center in western India. MATERIALS AND METHODS: This was a retrospective case record review of patients diagnosed between January 2010 and July 2022. The diagnosis was based on biochemical(inappropriately elevated serum FSH/LH) and pathologic (positive immunostaining for FSH/LH) features in patients with FGA, and elevated serum thyroid hormones and normal/elevated TSH in patients with TSHomas. RESULTS: We identified 11 patients with a total of six FGAs (median age 43.5 years, five men, one FGA cosecreting TSH, median largest dimension 40 mm, range 33-60 mm) and six TSHomas (median age 34.5 years, four women, two TSHomas cosecreting GH, median largest dimension 42.5 mm, range 13-60 mm). Symptoms of sellar mass effects led to pituitary imaging in most patients with FGA. Patients with TSHomas had symptoms of excess hormone secretion (GH/TSH) or sellar mass effects. The TSHomas that cosecreted GH/FSH were larger than those secreting only TSH. Transsphenoidal resection was the most common first-line therapy but significant residual disease was frequent (3 out of 6 FGAs and 4 out of 5 TSHomas). CONCLUSION: This is the first and second case series of FGAs and TSHomas, respectively, from India. In this study, TSHomas presented at younger age, were larger andhad low surgical cure rates
