Intensified seed spices-based cropping systems for higher productivity, resource-use efficiency, soil fertility and profitability in arid and semi-arid regions of India.

Coriander, fenugreek, nigella etc. are collectively known as seed spices. They are "High value and low volume crops" and considered cash crops for the growers of arid and semi-arid regions of India. Coriander, fenugreek and nigella are grown during the rabi season and take hardly 130-140 days to attain full maturity. In this context, farmers are not able to develop income from available arable land round the year, even though they have sufficient resources as well as manpower. Therefore, coriander, fenugreek and nigella-based cropping systems, four of each (total 12) were evaluated during 3 consecutive years (2019-20 to 2021-22) for their productivity, resource-use efficiency, economics and soil fertility. The results showed that among the seed spices-based cropping systems, maximum system productivity (5193 kg ha-1), production efficiency (18.81 kg ha-1 day-1), water-use efficiency (2.31 kg ha-1 mm-1), economic efficiency (11.85 US $ ha-1 day-1), net return (3270 US $ ha-1), benefit:cost ratio (3.27) and available N (165.6 kg ha-1) were observed under nigella-green coriander-mungbean cropping system. Hence, seed spices growers are recommended to adopt nigella-green coriander-mungbean cropping system in order to realize better productivity, resource-use efficiency, soil fertility and profitability.

A review on the pollution assessment of hazardous materials and the resultant biorefinery products in Palm oil mill effluent.

The voluminous nature of palm oil mill effluent (POME) is directly associated with environmental hazards and could be turned into biorefinery products. The POME, rich in BOD, COD, and oil and grease, with few hazardous materials such as siloxanes, fatty acid methyl ester, and phenolic compounds that may significantly increase the risk of violating the effluent quality standards. Recently, the application of chemical and biological risk assessment that can use electrochemical sensors and microalgae-like species has gained paramount attention towards its remediation. This review describes the existing risk assessment for POME and recommends a novel assessment approach using fish species including invasive ones as suitable for identifying the toxicants. Various physico-chemical and biological treatments such as adsorption, coagulation-flocculation, photo-oxidation, solar-assisted extraction, anaerobic digestion, integrated anaerobic-aerobic, and microalgae cultivation has been investigated. This paper offers an overview of anaerobic technologies, with particular emphasis on advanced bioreactors and their prospects for industrial-level applications. To illustrate, palmitic acid and oleic acid, the precursors of fatty acid methyl ester found in POME pave the way to produce biodiesel with 91.45%. Although there are some challenges in attaining production at an economic scale, this review offers some opportunities that could help in overcoming these challenges.

Cost-Effective Home Mechanical Ventilation in Neurosurgery Patients: Case Series of Three Patients.

Background Neurological patients who are ventilator-dependent occupy scarce beds in the hospitals for prolonged periods of time. Most, if not all, can be discharged on home mechanical ventilation (HMV). However, due to lack of insurance and state support, it remains prohibitively expensive for the vast majority of those who require it most. Materials and Methods The authors discuss three patients admitted in the Department of Neurosurgery between January and August 2019, who were discharged on HMV after remaining on ventilator support for prolonged period in the hospital. Each patient was discharged with two units (one as standby) of AgVa home ventilator (AgVa Healthcare; New Delhi, India), one Ambu-bag, one pulse oximeter, and one backup power supply unit capable of supplying power to ventilator for a minimum of 24 hours. All the equipment were given free-of-cost through donations by hospital staffs and other donors. All patients were followed up telephonically from their homes and the incidence of complications, ventilator malfunction, and additional cost of HMV on the families were ascertained. Observation and Results Of the three patients, two were male and one female. Age ranged from 12 to 17 years. The duration of in-hospital ventilator support prior to discharge on HMV varied from 1 to 5 years. There was no insurance cover available for any of the patients with all expenses being "out of pocket." The equipment cost Indian Rupees (INR) 115,700 (USD 1,615: two units of AgVa home ventilator costing INR 100,000 [USD 1,396], one Ambu-bag costing INR 1,100 [USD 15], one pulse oximeter costing INR 1,600 [USD 22], and one backup power supply unit costing INR 13,000 [USD 182]). Discharge on HMV was planned on specific request from patients' families and informed consent was taken from all. All patients had tracheostomies. Mode of HMV was pressure support ventilation in all. Telephonic follow-up ranged from 1 to 7 months. The cost of disposables was INR 100 per month (USD 0.7) for all the patients. No complications occurred in any patient. There was no incidence of ventilator-associated pneumonia (VAP) or ventilator malfunction. Conclusions Availability of cost-effective indigenous ventilator like AgVa home has made HMV possible, even for poor patients with neurological diseases, and has the potential to improve quality of life, decrease VAP rates, and free up scarce ventilator beds in hospitals. Longer-term follow-up in larger number of patients will improve the data on safety and feasibility in developing countries like India.

Assessment of left ventricular diastolic dysfunction in sub-clinical hypothyroidism.

BACKGROUND: Adverse cardiovascular effect of hypothyroidism has been identified in many studies. Early identification of patients with sub-clinical hypothyroidism may lead to early treatment and thereby favourable effect on cardiovascular morbidity and mortality. OBJECTIVES: To find out the association of sub clinical hypothyroidism and left ventricular dysfunction and also to find out relationship between systolic and diastolic dysfunction in these patients. MATERIAL AND METHODS: A total 30 cases of sub clinical hypothyroidism along with 15 age sex matched healthy control subjects were included in study. Serum TSH, T4, T3 hormone level was measured and those who were found to have sub-clinical hypothyroidism underwent for 2DEcho. RESULTS: Significant reduction in peak early filling velocity (PE) (p<0.001) and early filling time velocity integral (Ei) (p<0.001). Ratio of early and late peak velocities (PE/PA) (p<0.001), ratio of time velocity integral of early and atrial filling (Ei/Ai) (p<0.001) and ratio of the early peak to average velocity (PE/M) (p<0.001) were also reduced. Mean EF was 54.9± 5.55 as compared to 55.7 ± 3.46 of control subjects with a T.value of 0.48 ,however there was significant diastolic dysfunction in case of hypothyroid patients (mean Ei/Ai = 1.35 ± 0.53) as compared to control group subjects (mean Ei/AI = 2.11 ± 0.26) with a T value of 5.22. CONCLUSION: Sub-clinical hypothyroidism showed significant diastolic dysfunction in the absence of significant impairment of systolic function.

Women and sustainable development.

PIP: Gender issues in sustainable development focuses on constraints, the policy environment, land rights, the division of labor, reproductive rights, human resource development, productive energy, care of children, education, politics, security, social norms, and women's initiatives. African women's participation in the development process has been limited by the policy environment, sociocultural setting, and women's initiatives. African policy has not recognized the different roles that men and women play. There is unequal division of labor, legal discrimination against women, and abuse of women's basic human rights. Women's subordinate position in society and their concrete needs are ignored. Land tenure and credit systems are based on discriminatory policies. Women share a major portion and in some cases all of the agricultural labor with few tools or equipment. The operating assumption is that women's labor supply is inelastic. In order to fully participate in the development process, women need to be able to determine the number of children needed, the spacing between children, and the timing and the method of contraception. Human resource development in Africa has focused on training men. Women must contribute a major portion of time and labor to processing and cooking food in addition to caring for children. Access to higher education is limited. Political accords have been reached without women when women have contributed significantly to political struggles. Social security is compromised during violence and civil strife. There is sexual harassment in the work place. Culture can subordinate women. Women have been unable to change policy making, planning, and patriarchal ideology. Women are marginal contributors to the labor force. Income-generating projects are primarily confined to the informal sector. The governments impose the women's programs. Political influence is highly desired if change in women's stature is to be accomplished.^ieng
