Majorana Neutrino Masses from Anomalous U(1) Symmetries
We explore the possibility of interpreting the solar and atmospheric neutrino
data within the context of the Minimal Supersymmetric Standard Model augmented
by a single U(1) anomalous family symmetry spontaneously broken by non-zero
vacuum expectation values of a pair of singlet fields. The symmetry retains a
dimension-five operator which provides Majorana masses for left-handed neutrino
states. Assuming symmetric lepton mass matrices, the model predicts inverse
hierarchical neutrino mass spectrum, theta_{13}=0 and large mixing while at the
same time it provides acceptable mass matrices for the charged fermions.Comment: 14 pages, no figure
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
Agricultural land use planning-an effective means of enhancing tribal farmers' income in Asom
Not AvailableThe north-eastern region of India is blessed with rich biodiversity, wide range of agro-climatic
conditions and varied topography, which offer vast potentiality for agriculture in this region.
However, the region is lagging much behind in agricultural development compared to the other
region of the country. The reasons include injudicious use of land resources, poor dissemination of
new agro-technologies, low consumption of fertilizers and inadequate infrastructure facilities.
Agriculture is the major economic activity in the region and majority of the population, including
tribals, are dependent on agriculture. Interestingly, adoption of modern agricultural technologies
is still lower among the tribal population accounting for 27% of the total population in the northeastern region.Not Availabl

Not AvailableMulberry (Morus indica L.) is an agroforestry species grown extensively in India as multipurpose tree. In north
eastern India, it is cultivated as sole crop for rearing silkworm under low management practices without any
chemical fertilizers and organic inputs. Besides, limited scope of incorporation of mulberry leaves in soil prevents the addition of organic matter into soil. Therefore, the quality of mulberry leaf as well as silk solely depends on the nutritional status of soil on which mulberry is grown. In the present investigation, an attempt was made to assess the fertility status of soil under mulberry cultivation as sole crop in six rural development blocks namely, Kakodonga, Dergaon, Kathalguri, Podumoni, Sarupathar and Bokakhat of Golaghat district in upper Brahmaputra valley of Assam in north eastern India. Results indicated that soils were extremely to strongly acidic (pH < 5.5) in 44% of the mulberry gardens. Organic carbon content was medium to high in 80% of the surface soil samples (0-20 cm.) and low to medium in 84% of sub-surface soil samples (20-50 cm.). About 51% of the sub-surface soil samples were low in N and 98% of the sub-surface soil samples were low in P status. Among micronutrients, B was deficient in more than 80% samples; whereas, Zn deficiency was found in 36% of the sub-surface samples. Nutrient index values indicated that mulberry growing soils of Kakodonga and Bokakhat were the least fertile as far as the availability of major nutrients are concerned due to the soil resources of recent origin (Entisols) with coarse texture occurring on active flood plains in these blocks. The study indicated the wide spread nutritional deficiency in soils of upper Brahmaputra valley of north eastern India.Not Availabl
