Enhancement of dronogram aid to visual interpretation of target objects via intuitionistic fuzzy hesitant sets
In this paper, we address the hesitant information in enhancement task often caused by differences in image contrast. Enhancement approaches generally use certain filters which generate artifacts or are unable to recover all the objects details in images. Typically, the contrast of an image quantifies a unique ratio between the amounts of black and white through a single pixel. However, contrast is better represented by a group of pix- els. We have proposed a novel image enhancement scheme based on intuitionistic hesi- tant fuzzy sets (IHFSs) for drone images (dronogram) to facilitate better interpretations of target objects. First, a given dronogram is divided into foreground and background areas based on an estimated threshold from which the proposed model measures the amount of black/white intensity levels. Next, we fuzzify both of them and determine the hesitant score indicated by the distance between the two areas for each point in the fuzzy plane. Finally, a hyperbolic operator is adopted for each membership grade to improve the pho- tographic quality leading to enhanced results via defuzzification. The proposed method is tested on a large drone image database. Results demonstrate better contrast enhancement, improved visual quality, and better recognition compared to the state-of-the-art methods.Web of Science500866
Impact of Physical Education Curriculum on Academic Achievement of Higher Secondary School Students in India
In the present study, the researchers were mainly interested in investigating the impact of PE curriculum on the academic achievements of the Higher Secondary (HS) level (10+2) students belonging to two different educational boards in India i.e., West Bengal Council of Higher Secondary Education (WBCHSE) and Central Board of Secondary Education (CBSE). On the basis of simple randomization, one hundred eighty (N=180) HS level boys were selected from four schools (two schools from each board) as participants for the present study. Among 180 students, 120 students [60 from each educational board, WBCHSE acted as experimental Group-I (EGWB–I); CBSE acted as experimental Group-II (EGCB–II)] were so selected that they had PE as a compulsory subject and rest, 60 students [30 from each educational board, simultaneously acted as Control Group (CGWB+CB)] had either computer science or painting as a compulsory subject in place of PE. The students of EGWB–I & EGCB–II underwent two different PE curriculums as training interventions over an academic year (11 months). But the CGWB+CB did not receive any PE curriculum as a training intervention. The student’s academic achievement was measured by obtained marks in two common subjects (Bengali and English) for both boards. It was standardized through T-score and finally, composite T-score were calculated for all the subjects to draw statistical inference on academic achievement. Statistical inference on academic achievement among the groups in baseline and post-test were drawn through ANCOVA followed by Tukey's LSD post-hoc test. Significance was tested at p<.05 level. Both EGWB–I & EGCB–II showed a significant difference compared to the CGWB+CB in academic achievement. But no significant difference was observed between EGWB–I & EGCB–II. The academic achievement of the students having PE as a subject improved significantly compared to the students having no PE as a compulsory subject in both boards. But the PE curriculum in both boards was found to be equally effective for developing students' academic achievement
Cerebrospinal fluid adenosine deaminase level as a diagnostic marker in adult tuberculous meningitis: a study conducted in a tertiary care hospital of Eastern India
Background: Tubercular meningitis is one of the highly prevalent form of meningitis in the world and is a significant cause of morbidity and mortality in developing countries like India. Lack of early and timely diagnosis and subsequent initiation of treatment makes the fatality rate even higher. Cerebrospinal fluid (CSF) analysis is most important aspect of lab diagnosis in tuberculous meningitis (TBM) worldwide. The objective of this study was to study the cerebrospinal fluid CSF adenosine deaminase (ADA) levels in TBM and non-TBM meningitis cases and to determine its diagnostic significance as a biochemical marker of TBM infection.Methods: The study population comprised three different patient groups. TBM (n=36), pyogenic meningitis (n=17) and aseptic meningitis group (n=12). Total 75 subjects were enrolled consecutively in the study and CSF specimens were collected from them. ADA and other cytological and biochemical estimation were carried out using standard protocol.Results: ADA level in TBM in compare to non-TBM was more and mean ADA level of TBM, AM and PM are 26.423±3.8, 2.602±0.5 and 6.29±0.3 respectively. There are highly significant differences between the TBM and non-TBM groups and also in compare with individual groups.Conclusions: CSF ADA levels are elevated in the TBM cases as compared to the non-TBM - meningitis cases. Results are statistically significant. It is a simple and inexpensive diagnostic adjunctive test in the rapid and early diagnosis of TBM
Sector Specific Inflow of capital, Non-Traded sector and an Increase in Real Exchange Rate
This paper attempts to look at the effect of inflow of foreign capital only in the exportable sector on the factor prices and real exchange rate of the concerned economy. In doing so we frame a blend of Heckscher-Ohlin and Specific Factor model of trade which is popularly known as H-O nugget. We show that consequent upon an inflow of capital specific to exportable sector both the non-traded good production and return to the factor specific to non-traded good are reduced while the exportable production expands. The effect of such an inflow on real exchange rate is unambiguous and it increases
Role of Multipurpose Projects on Distribution of Cropping Intensity and Canal Irrigation: A Study on DVC Projects of the Middle Damodar River Valley of West Bengal
The river valley projects with many objectives are called multipurpose project. Multipurpose project in the Damodar River played a major role not only as a flood controller but also as a source of canal irrigation. Middle and lower course of the river are the most prominent area where irrigation systems are largely controlled by DVC projects of Damodar River. Several canal systems has also developed after construction of dams in DVC project of Damodar River Valley. The study area falls under the area in between Panchet Dam and Burdwan Town. It is extended up to 23º28’ N to 23º41’N latitude and 86 º 44 ’E to 87 º 18’ E longitudes. Total length of the area is approximately 70 km. the avg. height of this area is 110 m from the sea level. To show the increase of Agricultural Land in downstream section Damodar River Basin, block wise Cropping Intensity distribution has been calculated for showing locational and temporal. In this river valley, the area under Agricultural Land has been drastically increased (15%) from 1990 to 2010 but there are slightly increase in the Built up areas. The western side of the basin have the low cropping intensity in the Burdwan District. Upper reaches are less fertile that is why production is also low and reverse condition are found in the lower reaches of the river basin area. The downstream of the river valley are pure alluvial track of the Ganga River system and this region are more fertile than the upstream region. Whole basin area is bounded with agricultural and industrial activities. Irrigation also can put impetus on the agricultural output of this valley region especially in the downstream areas of the valley. Thus the dams are severally interlinked with the human settlement and landscapes of the Damodar Valley Region.

Foreign capital and exchange rate movement in developing economies: a theoretical note
This study attempts to provide with underlying theoretical explanations for exchange rate appreciation due to foreign capital inflow. We use an extended three sector specific factor model to explain why and how an inflow of foreign capital boosts the price of a nontradable good that helps tilting the exchange in rate in favor of the host country. We also strive to look at the possible consequences on factor prices and on sectoral de-composition of a representative economy
Hairy root culture: a potent method for improved secondary metabolite production of Solanaceous plants
Secondary metabolites synthesized by the Solanaceous plants are of major therapeutic and pharmaceutical importance, many of which are commonly obtained from the roots of these plants. ‘Hairy roots’, mirroring the same phytochemical pattern of the corresponding root of the parent plant with higher growth rate and productivity, are therefore extensively studied as an effective alternative for the in vitro production of these metabolites. Hairy roots are the transformed roots, generated from the infection site of the wounded plants with Agrobacterium rhizogenes. With their fast growth, being free from pathogen and herbicide contamination, genetic stability, and autotrophic nature for plant hormones, hairy roots are considered as useful bioproduction systems for specialized metabolites. Lately, several elicitation methods have been employed to enhance the accumulation of these compounds in the hairy root cultures for both small and large-scale production. Nevertheless, in the latter case, the cultivation of hairy roots in bioreactors should still be optimized. Hairy roots can also be utilized for metabolic engineering of the regulatory genes in the metabolic pathways leading to enhanced production of metabolites. The present study summarizes the updated and modern biotechnological aspects for enhanced production of secondary metabolites in the hairy root cultures of the plants of Solanaceae and their respective importance
Suitable dietary protein/lipid of hybrid, female red sea bream Pagrus major and Male Black Sea Bream Acanthopagrus schlegeli in Juvenile Stage, as compared with Red Sea Bream
To determine a suitable dietary protein/lipid (CP/CL) ratio in the early juvenile stages of hybrid porgy (F1), female red sea bream (RSB) × male black sea bream, five diets with various CP/CL ratios—60/7, 55/12, 51/17, 46/23, and 41/28—were prepared and provided to juveniles in triplicate. At the smaller juvenile stage, F1, weighing 0.32 g, a significantly higher specific growth rate (SGR) and feed efficiency (FE) were seen with 60/7 and 55/12 diets. However, in RSB weighing 0.26 g, SGR and FE were higher
with the 60/7 diet than the other diets at 21°C. At the larger juvenile stage, F1, weighing 3.7 g, there was no significant difference in SGR or FE among the diets, but RSB weighing 4.0 g fed 60/7, 55/12, and 51/17 diets had higher SGR and FE than 46/23 and 41/28 diets at 24°C. Moreover, survival and apparent nutrient retention of F1 at both stages were significantly higher than those in
RSB. These results indicate that both F1 and RSB weighing ca. 0.3 g require a higher dietary CP/CL than those weighing ca. 4 g. Additionally, F1 in both trials showed the suitability of a lower dietary CP/CL than RSB, indicating that mass production of F1 juveniles will be more economical than RSB
Open and Closed Lip Schizencephaly in Seckel Syndrome: A Case Report
Abstract Seckel syndrome (Online Mendelian Inheritance in Man database Number 210600) is the classic prototype of primordial bird-headed dwarfism. In addition to the characteristic craniofacial dysmorphism and skeletal defects, abnormalities of the cardiovascular, hematopoietic, endocrine, and central nervous systems are described. The full phenotypic spectrum of this clinically and genetically heterogeneous syndrome is yet to be delineated. Presented herein is a boy 2 years and 5 months old, with Seckel syndrome, born to second-degree consanguineous Muslim parents. In addition to the classic phenotype of the disorder, this patient had both, an open and a closed lip schizencephaly detected on cranial computed tomography (CT) scan. To our knowledge, the association of schizencephaly and Seckel syndrome is not described previously in the English language literature. In addition, presented briefly is a review of the anatomical cerebral cortical malformations associated with this syndrome. Seckel syndrome (Online Mendelian Inheritance in Man database Number 210600) is a rare form of primordial dwarfism, which was initially described in 1960. Keywords 1 Since the initial description, more than 60 cases are reported; however, less than one third appear to fulfill the criteria originally set forth by Seckel. 2 Among the generally accepted minimal criteria are severe intrauterine and postnatal dwarfism; severe microcephaly with mental retardation; and facial anomalies, including a receding forehead and chin, large beaked nose, and large or bulging eyes. 1 Presented herein is a child with classic Seckel phenotype, who had both an open and a closed lip schizencephaly, resulting in global developmental delay and bilateral sensorineural deafness. Case Report A 2-year 5-month-old boy, born to a 28-year-old second-degree consanguineous Muslim mother, was initially seen for his unusual ''facial appearance,'' small body stature, and for possible evaluation of developmental delay. He was born by spontaneous vaginal delivery at term and had an uneventful immediate postnatal period. The mother had 2 episodes of spontaneous miscarriage at 12th and 16th weeks of gestation in the past. She had an uneventful present pregnancy, without exposure to unusual medications, radiation, or trauma. A single antenatal ultrasound performed at 16 weeks of gestation was reportedly normal. The birth weight, length, and the head circumference of the baby were 1800 g, 37 cm, and 28 cm, respectively (all much below the third percentile). At presentation, he weighed 4250 g and stood 53 cm tall (both being significantly below the third percentile). The anthropometry revealed the following values: upper body segment to lower body segment ratio: 1.1; head circumference: 31 cm; arm span: 51 cm; upper limb length: 18 cm bilaterally with upper segment to lower segment ratio of 0.85; midarm circumference taken midway between the tip of acromian and the olecranon process: 7.5 cm bilaterally. The ratio of upper leg segment to the lower leg segment was 1.15. The chest and the abdominal circumference were 30.5 and 31 cm, respectively. The phenotype revealed a small head with sloping forehead, completely fused anterior and posterior skull fontanel with sutural ridges, relative micrognathia, bilaterally low-set ears, high-arched palate, prominent aquiline nos
