Assessment of Pesticide Use in Major Vegetables From Farmers\u27 Perception and Knowledge in Dhading District, Nepal
A field study was carried out to assess the pesticide use status in major vegetable crops from farmers\u27 perception and knowledge in Dhading, Nepal in 2019. Field study was carried with 100 commercial farmer\u27s using semi-structure questionnaire by face to face interview. This study was analyzed by categorization of farmers into small holder (51) and large holder (49) groups on the basis of mean area of vegetable cultivation (6.48 ropani). The highest amount of pesticides is needed in tomato in both large holders and small holders according to the farmer\u27s experience. Among the study farmer\u27s, 41% of them spray the pesticides by making a cocktail or mixed method and 56% follow the waiting period of 3-5 days in both of the cases. A significant positive correlation was found at 5% level of significance between the knowledge and practice pattern of waiting period of the pesticides and negative correlation was found between the Personal Protective equipment score and health hazard score. Headache was the major health hazards faced by the farmers which was higher in small holders (66.7%) as compared to the large holders (46.9%). Mask was the most used PPE by the farmer\u27s i.e. by 83% in overall. Fourty three percent of the farmer\u27s throw the pesticide containers in secret place after using of it.The use of PPE was seen lower in small holders as compared to the large holders. This study reveals the necessities of suitable program and policies regarding the knowledge, safe handling and use of pesticide among the farmer\u27s level
Closing the Employment Standards Enforcement Gap, An Agenda for Change
Precarious employment is increasing in Ontario. A growing share of Ontario’s private sector employees earns low wages while a shrinking portion belongs to unions. These trends are fueled by changes in the structure of Ontario’s labour force. In many industries, including accommodation and food services, administrative services, and cleaning, workplaces are being transformed through greater use of contracting out, franchising, and extended supply chains. These ways of structuring work contribute to driving working conditions downward
Detection of Target ssDNA Using a Microfabricated Hall Magnetometer with Correlated Optical Readout
Sensing biological agents at the genomic level, while enhancing the response time for biodetection over commonly used, optics-based techniques such as nucleic acid microarrays or enzyme-linked immunosorbent assays (ELISAs), is an important criterion for new biosensors. Here, we describe the successful detection of a 35-base, single-strand nucleic acid target by Hall-based magnetic transduction as a mimic for pathogenic DNA target detection. The detection platform has low background, large signal amplification following target binding and can discriminate a single, 350 nm superparamagnetic bead labeled with DNA. Detection of the target sequence was demonstrated at 364 pM (<2 target DNA strands per bead) target DNA in the presence of 36 μM nontarget (noncomplementary) DNA (<10 ppm target DNA) using optical microscopy detection on a GaAs Hall mimic. The use of Hall magnetometers as magnetic transduction biosensors holds promise for multiplexing applications that can greatly improve point-of-care (POC) diagnostics and subsequent medical care
Nucleation of a sodium droplet on C60
We investigate theoretically the progressive coating of C60 by several sodium
atoms. Density functional calculations using a nonlocal functional are
performed for NaC60 and Na2C60 in various configurations. These data are used
to construct an empirical atomistic model in order to treat larger sizes in a
statistical and dynamical context. Fluctuating charges are incorporated to
account for charge transfer between sodium and carbon atoms. By performing
systematic global optimization in the size range 1<=n<=30, we find that Na_nC60
is homogeneously coated at small sizes, and that a growing droplet is formed
above n=>8. The separate effects of single ionization and thermalization are
also considered, as well as the changes due to a strong external electric
field. The present results are discussed in the light of various experimental
data.Comment: 17 pages, 10 figure
Tackling the problem of overweight and obesity: the Dutch approach.
OBJECTIVE: The aim of this article is to share the Dutch experience of a nation-wide approach to reduce the prevalence of overweight and obesity. This is an practice example of national health policy. METHODS: The Ministry of Health facilitates three complementary initiatives to tackle overweight and obesity: i) the Knowledge Centre Overweight (KCO) (since 2002) to enhance knowledge about prevention and treatment of overweight, ii) the Covenant on Overweight (CO) (since 2005), a public-private partnership, iii) the Partnership Overweight Netherlands (PON) (since 2008), to facilitate the development and implementation of a chronic disease management model. RESULTS: The KCO has a platform with 20 partners that functions as a sounding board. It consists of specialists in the area of overweight and obesity. Moreover KCO has a well-visited website: www.overgewicht.org. The CO with 20 partners from the (local) government, private and public sector has instigated various activities regarding the settings home, school, work, and recreation. The PON has the commitment of 18 partners (organisations of health care providers, health insurance companies and patient organisations) and facilitates the implementation of the national clinical guideline for the diagnosis and treatment of obesity. CONCLUSION: In the Netherlands relevant stakeholders work together at all levels. The ambition is to make this the first integrated, practice-and evidence-based, national approach for tackling overweight and obesity
Frequency and Practice-Level Variation in Inappropriate Aspirin Use for the Primary Prevention of Cardiovascular Disease Insights From the National Cardiovascular Disease Registry’s Practice Innovation and Clinical Excellence Registry
AbstractBackgroundAmong patients without cardiovascular disease (CVD) and low 10-year CVD risk, the risks of gastrointestinal bleeding and hemorrhagic strokes associated with aspirin use outweigh any potential atheroprotective benefit. According to the guidelines on primary prevention of CVD, aspirin use is considered appropriate only in patients with 10-year CVD risk ≥6% and inappropriate in patients with 10-year CVD risk <6%.ObjectivesThe goal of this study was to examine the frequency and practice-level variation in inappropriate aspirin use for primary prevention in a large U.S. nationwide registry.MethodsWithin the National Cardiovascular Disease Registry’s Practice Innovation and Clinical Excellence registry, we assessed 68,808 unique patients receiving aspirin for primary prevention from 119 U.S. practices. The frequency of inappropriate aspirin use was determined for primary prevention (aspirin use in those with 10-year CVD risk <6%). Using hierarchical regression models, the extent of practice-level variation using the median rate ratio (MRR) was assessed.ResultsInappropriate aspirin use frequency was 11.6% (7,972 of 68,808) in the overall cohort. There was significant practice-level variation in inappropriate use (range 0% to 71.8%; median 10.1%; interquartile range 6.4%) for practices; adjusted MRR was 1.63 (95% confidence interval [CI]: 1.47 to 1.77). Results remained consistent after excluding 21,052 women age ≥65 years (inappropriate aspirin use 15.2%; median practice-level inappropriate aspirin use 13.8%; interquartile range 8.2%; adjusted MRR 1.61 [95% CI: 1.46 to 1.75]) and after excluding patients with diabetes (inappropriate aspirin use 13.9%; median practice-level inappropriate aspirin use 12.4%; interquartile range 7.6%; adjusted MRR 1.55 [95% CI: 1.41 to 1.67]).ConclusionsMore than 1 in 10 patients in this national registry were receiving inappropriate aspirin therapy for primary prevention, with significant practice-level variations. Our findings suggest that there are important opportunities to improve evidence-based aspirin use for the primary prevention of CVD
Weaponising microbes for peace
There is much human disadvantage and unmet need in the world, including deficits in basic resources and services considered to be human rights, such as drinking water, sanitation and hygiene, healthy nutrition, access to basic healthcare, and a clean environment. Furthermore, there are substantive asymmetries in the distribution of key resources among peoples. These deficits and asymmetries can lead to local and regional crises among peoples competing for limited resources, which, in turn, can become sources of discontent and conflict. Such conflicts have the potential to escalate into regional wars and even lead to global instability. Ergo: in addition to moral and ethical imperatives to level up, to ensure that all peoples have basic resources and services essential for healthy living and to reduce inequalities, all nations have a self-interest to pursue with determination all available avenues to promote peace through reducing sources of conflicts in the world. Microorganisms and pertinent microbial technologies have unique and exceptional abilities to provide, or contribute to the provision of, basic resources and services that are lacking in many parts of the world, and thereby address key deficits that might constitute sources of conflict. However, the deployment of such technologies to this end is seriously underexploited. Here, we highlight some of the key available and emerging technologies that demand greater consideration and exploitation in endeavours to eliminate unnecessary deprivations, enable healthy lives of all and remove preventable grounds for competition over limited resources that can escalate into conflicts in the world. We exhort central actors: microbiologists, funding agencies and philanthropic organisations, politicians worldwide and international governmental and non-governmental organisations, to engage – in full partnership – with all relevant stakeholders, to ‘weaponise’ microbes and microbial technologies to fight resource deficits and asymmetries, in particular among the most vulnerable populations, and thereby create humanitarian conditions more conducive to harmony and peace.Natural History Museum; Indian National Science Academ
Transmission of HIV-1 infection in sub-Saharan Africa and effect of elimination of unsafe injections
During the past year, a group has argued that unsafe injections are a major if not the main mode of HIV-1 transmission\ud
in sub-Saharan Africa. We review the main arguments used to question the epidemiological interpretations on the lead\ud
role of unsafe sex in HIV-1 transmission, and conclude there is no compelling evidence that unsafe injections are a\ud
predominant mode of HIV-1 transmission in sub-Saharan Africa. Conversely, though there is a clear need to eliminate\ud
all unsafe injections, epidemiological evidence indicates that sexual transmission continues to be by far the major\ud
mode of spread of HIV-1 in the region. Increased efforts are needed to reduce sexual transmission of HIV-1
Effect of Different Auxins Alone and Mixture of Benzene Aminopurine (BAP) and Kinetin (Kn) Along with Auxin 2,4-D on In Vitro Growth and Multiplication of Callus in B5 Medium Derived from Embryonic Cotyledon Excised Explants of Ashwagandha (Cultivated)
ABSTRACT Ashwagandha (Withania somnifera) belongs to the member of family Solanaceae, having enormous aromatic properties and medicinal properties, has been included in an ancient (early) text of Ayurveda. It is very useful as an, contraceptive, amoebocide, bactericide, abortifacient, anodyne, and diuretic. But the risks of fungal infections are very high in these plants. Due to its over use this plants is going towards extinction so in vitro microprogation is a best method to protect this plant as well as to produced value added compounds in a very short time without any external environmental hazards. Higher percentage of in vitro morphogenic response was exhibited by explants mature embryo followed by explants mature cotyledon leaves. Half B5 medium (gamborg medium) with NAA, IBA, 2,4-Di-chlorophenyl acetic acid (2,4-D), BAP, Kinetin (Kn) and Sucrose (5% w/v) was employed either separately or in mixture. Cotyledonary leaves are generally produces callus in callus induction media and after several sub culturing its produces shoots and roots in shoot and root induction media. Regenerated plantlets were obtained successfully in the field after hardening. Mostly for in vitro organogenesis MS medium has been employed bus it has been also done in B5 medium with cotyledonary leave's explants of Withania somnifera
