Introduction
Consequence of lopsided blood-thinning-drug, lowering blood-viscosity (BV), is bleeding and very frequently asymptomatic-hemorrhage (AH) and the acute-heart-failure (AHF) happen. V.R.S.Kumar et al. (2020) reported that such asymptomatic episodes are due to the internal flow choking in the cardiovascular system (CVS) at a critical blood-pressure-ratio (BPR), which is regulated by biofluid/blood heat capacity ratio (BHCR).
Methods
The closed-form-analytical-methodology is used for correlating BV, BPR, BHCR, vessel geometry and ejection fraction (EF). In vitro method is used for the BHCR estimation of healthy subjects. In silico method is used for demonstrating the Sanal flow choking.
Results
The analytical models reveal that the relatively high and low BV are risk factors of internal flow choking. In vitro study shows that N2, O2, CO2 & Ar gases are predominant in fresh-blood samples of the healthy subjects at a temperature range of 37-400 C (98.6-1040 F), which increases the risk of flow-choking. In silico results demonstrated the Sanal flow choking followed by the shock wave generation and pressure-overshoot in a simulated artery with the divergent/bifurcation region.
Conclusions
An overdose of blood-thinning drug reduces BV and increases Reynolds number causing high-turbulence leading to the Sanal flow choking. Asymptomatic stroke could be diminished by concurrently lessening the BV and flow turbulence by rising thermal tolerance level in terms of BHCR or by decreasing the BPR. In conclusion, BPR must always be lower than 1.8257 as dictated by the lowest BHCR of the evolved gas for prohibiting asymptomatic stroke

Effects of canopy cover on fruiting intensity and fruit removal of a tropical invasive weed
No full textLantana camara (hereafter, Lantana) is among the worst invasive alien plants spread extensively across Africa, Australia and Asia at an alarming rate, posing significant challenges to conservation of native biodiversity. While, Lantana invasion is widely recognised to be more pronounced in open-canopy habitats (including deciduous forests, forest edges and gaps), the potential role of variation in seed dispersal across habitats varying in overstory canopy cover is poorly understood. Avian frugivores are among primary seed dispersers of the fleshy-fruited Lantana. We monitored 45 Lantana shrubs across a gradient of overstory canopy cover to determine the relationship between fruiting intensity and canopy cover. We watched 80 Lantana shrubs (240 h) across a canopy cover gradient to determine 1) differences in frugivore assemblage visiting Lantana across open- and closed-canopy habitats, 2) drivers of frugivore visitation on Lantana, and 3) relationship between seed disperser visitation rate and overstory canopy cover. We found that Lantana shrubs under low overstory canopy cover had higher fruit abundance than those in high canopy cover. Frugivore assemblage differed between Lantana shrubs in open- versus closed-canopy cover habitats. Drivers of frugivore visitation on Lantana varied across different frugivore species with a greater probability of occurrence of bulbuls (the primary seed dispersers of Lantana) on shrubs under low overstory canopy cover. Visitation rates of the effective seed dispersers were higher on shrubs under low overstory canopy cover. Thus, there was greater chances of dispersal of seeds in habitats with low overstory canopy cover. The study demonstrates variable fruiting intensity and fruit removal rate as a driver of differences in dispersal of seeds across habitats. It highlights greater vulnerability of open habitats to invasion and the need to prioritise Lantana management efforts in open habitats. Anthropogenic activities that lead to canopy openings (e.g. tree lopping and logging) likely facilitate Lantana invasion through greater fruit production and seed dispersal.The project contains data on variation in fruiting phenology, frugivore composition, and seed disperser visitation on invasive Lantana camara across open and forest habitats in the Western Himalayan region of India. The data was collected by Ms Yukti V.Taneja for her master's dissertation study in Wildlife Institute of India (WII) under the guidance of Dr. Navendu Page and R. Suresh Kumar of WII and Dr. Rohit Naniwadekar of Nature Conservation Foundation (NCF, India). Data were collected from open shrubland-grassland mosaics and Shorea-robusta dominated moist deciduous forest sites in and around the WII campus. The manuscript related to the study has been accepted in Forest Ecology and Management and will be available shortly. The title of the manuscript is "Effects of Canopy Cover on Fruiting Intensity and Fruit Removal of a Tropical Invasive Weed". The authors of this article are Yukti V. Taneja, Navendu V. Page, R. Suresh Kumar and Rohit Naniwadekar.

Impacts of Watershed Development Programmes: Experiences and Evidences from Tamil Nadu
Get PDFThe overall performance of watershed development programmes has been examined in the state of Tamil Nadu. The impacts of major watershed development programmes have been outlined in terms of biophysical impacts, environmental impacts, socio-economic impacts and overall economic impacts. It is pointed out that the watershed development activities have made significant positive impacts on various biophysical aspects such as soil and water conservation, soil fertility, soil and water erosion in cropped area, changes in cropping pattern, cropping intensity, production and productivity of crops. Watershed development activities have shown significant positive impacts on water table, perenniality of water in wells, water availability for cattle and other domestic uses, etc. The overall economic impacts have been evaluated in terms of NPV, IRR and BCR. The peoples’ participation in watershed development activities has been found satisfactory but the optimal level is yet to be achieved. Training of farmers has been found effective in disseminating technical knowledge. According to the study, the future strategy should be the movement towards a balanced approach of matching the supply-driven menu with a set of demand-driven activities. Peoples’ participation, involvement of Panchayati Raj Institutions, local user groups and NGOs along side institutional support from different levels, viz. the Union Government, the state, the district and block levels should be ensured to make the programme more participatory, interactive and cost-effective. Convergence of various rural development programmes around the watershed could be ensured to promote holistic development of watersheds. For its continued success, the programme, should be economically efficient, financially viable, technically feasible and socially acceptable while ensuring equity. For, sustainable development, regular and routine monitoring of environmental parameters is important as environmental enhancement increases the credibility and acceptability of the programme.Agricultural and Food Policy,
