Evaluation of Traditional Mango (Mangifera indica L.) Varieties of Southern Kerala

Investigations were carried out at the Department of Pomology and Floriculture, College of Agriculture, Vellayani, to characterize traditional mango varieties of southern Kerala, based on utility of fruits. Wide publicity was made about the proposed study and an extensive survey was conducted. Fifty traditional mango types could be located from Thiruvananthapuram, Kollam, Pathanamthitta and Alappuzha districts. On evaluation three utility groups were identified, viz., pickling, table and dual purpose types, based on the survey. Variability could be observed for floral, fruit and quality attributes. Flowering round the year was observed in Vellari Type-1, Thali, Kizhakkan Thali and Ambalathara Local. Karpoora Varikka with carotenoid content higher than most leading, superior varieties was identified. Varieties with high content of total sugars were Nedungolan, Vellari Type-2, Perakka manga, Inamanga, Neenda Karpooram, Velutha Muvandan, Karpoora Varikka and Ambalathara Local. Pickling type mangoes gave highest average ascorbic acid content (46.02mg/ 100g). Average titrable acidity (%) and crude fibre content were also the highest in pickling types (1.22% and 1.18%, respectively). In organoleptic evaluation, Perakka manga, Nedungolan, Karpooram manga, Vellari Type-2, Neenda Karpooram, Muthalamookan, Inamanga, Ambalathara Local, Kotookonam Varikka and Velutha Muvandan ranked on top in overall acceptability. These traditional varieties with desirable traits can be used for developing molecular markers to identify particular genes of interest and transfer them to desirable cultivars through genetic engineering

Depression, anxiety and stress among COVID positive pregnant women

Background: Impact of the news that patient is covid positive may increase the risk of depression and anxiety among the vulnerable population such as pregnant women. Aims of the study were to estimate the prevalence of depression, anxiety and stress among covid positive pregnant women. To evaluate the demographic and obstetric factors contributing to the psychological manifestations in covid positive pregnant women.Methods: A cross sectional descriptive study was conducted at a tertiary hospital of North Kerala from July to August 2020. The demographic and factors were recorded and DASS 21 self-reported questionnaire was used to assess depression, anxiety and stress.Results: We found that using the DASS 21 scoring system, 37.5% out of the 120 study subjects were having psychological symptoms either of depression, anxiety or stress. Depression was seen in 32 (26.7%), anxiety in 29 (24.2%) and stress in 14 (11.7%) of the study participants. The psychological symptoms of depression and anxiety were more pronounced in those with low education, unemployed and in the first and third trimester of pregnancy.Conclusions: The current study shows that COVID-19 positive pregnant women have a high prevalence of depression and anxiety. Our findings can be used to formulate psychological interventions to improve mental health and psychological resilience during the COVID-19 pandemic

Learning Disabilities and Delinquent Behaviors among Adolescents: A Comparison of Those with and without Comorbidity

Research is inconclusive on whether adolescents with learning disabilities (LD) engage in more delinquency than adolescents without such deficits. Mixed results may result from a failure to account for the effects of co-occurring disabilities. Using the National Longitudinal Study of Adolescent Health, this study examines delinquency among adolescents without disabilities to youth with LD, Attention Disorder Symptoms (ADS), and comorbid LD/ADS. Results indicate no significant differences in property offenses, or alcohol, tobacco, and marijuana use; however, youth with LD reported significantly more violence than non-disabled youth. Findings illustrate the heterogeneous effects various disabilities have on delinquent behavior. Future research and policy implications will be discussed

Quinolinium Dichromate Oxidation of Aliphatic Aldehydes: A Kinetic Study

Kinetic data on the rates of quinolinium dichromate oxidation of a series of aliphatic aldehydes have been determined and discussed with reference to aldehyde hydration equilibria. Kinetic results support a pathway proceeding via a rate-determining oxidative decomposition of a chromate ester of an aldehyde hydrate. A cyclic transition state is suggested; being a Hückel-type system (4n + 2), this would be an allowed process. The deuterium isotope effect for the oxidation of acetaldehyde (kH / kD = 6.4) indicated a carbon-hydrogen cleavage rather than a carbon-carbon cleavage

Archimedes' law and its corrections for an active particle in a granular sea

We study the origin of buoyancy forces acting on a larger particle moving in a granular medium subject to horizontal shaking and its corrections before fluidization. In the fluid limit Archimedes' law is verified; before the limit memory effects counteract buoyancy, as also found experimentally. The origin of the friction is an excluded volume effect between active particles, which we study more exactly for a random walker in a random environment. The same excluded volume effect is also responsible for the mutual attraction between bodies moving in the granular medium. Our theoretical modeling proceeds via an asymmetric exclusion process, i.e., via a dissipative lattice gas dynamics simulating the position degrees of freedom of a low density granular sea.Comment: 22 pages,5 figure

Findings and Implications from a Project on White Supremacist Entry and Exit Pathways

One key lesson is that identity is central to entry and exit pathways

In vitro Cortical Network Firing is Homeostatically Regulated: A Model for Sleep Regulation.

Prolonged wakefulness leads to a homeostatic response manifested in increased amplitude and number of electroencephalogram (EEG) slow waves during recovery sleep. Cortical networks show a slow oscillation when the excitatory inputs are reduced (during slow wave sleep, anesthesia), or absent (in vitro preparations). It was recently shown that a homeostatic response to electrical stimulation can be induced in cortical cultures. Here we used cortical cultures grown on microelectrode arrays and stimulated them with a cocktail of waking neuromodulators. We found that recovery from stimulation resulted in a dose-dependent homeostatic response. Specifically, the inter-burst intervals decreased, the burst duration increased, the network showed higher cross-correlation and strong phasic synchronized burst activity. Spectral power below <1.75 Hz significantly increased and the increase was related to steeper slopes of bursts. Computer simulation suggested that a small number of clustered neurons could potently drive the behavior of the network both at baseline and during recovery. Thus, this in vitro model appears valuable for dissecting network mechanisms of sleep homeostasis

Monitoramento da extração de areia nos municípios não pertencentes ao Zoneamento Ambiental Minerário do trecho paulista da várzea do rio Paraíba do Sul.

Remote sensing techniques can significantly contribute to environmental monitoring of the low cost mineral extraction of sand pits. This study aims to evaluate the increase of sand pits mining activity between the period of 2004 to 2009, in municipalities of the Paraiba do Sul basin of São Paulo State, Brazil, that are not included in the mineral zoning of this basin. Visual interpretation of Landsat-5 (Thematic Mapper ? TM sensor) images indicated areas of sand extraction for the municipalities of Aparecida, Cachoeira Paulista and Roseira with an annual average increase of 10.1 ha, 20.5 ha and 33.5 ha, respectively. The municipality with the highest percentage of sand mining area increase was Lorena (233%). Results presented in this study can be used to justify the mineral zoning expansion to these municipalities
