Parthenium hysterophorus, often known as congers grass, is a noxious weed that is a member of the Asteraceae family of plants. Its natural habitats include the areas surrounding the Gulf of Mexico, Central America, Southern North America, the West Indies, and Central South America, among other places. Congress grass has risen to become one of the world’s seven most destructive and deadly weeds, according to the World Health Organization. This invasive plant is also a significant concern in India. It is responsible for a variety of illnesses and allergies in both people and animals. Aside from that, there is some potential for this plant to be used as an insecticide, herbicide, fungicide, wood preservative, anti-amoebic, and even for medicinal purposes. If any species, particularly an invasive weed, is to be evaluated for its ability to benefit living organisms, it is necessary to have a thorough understanding of both its positive and negative impacts. As a result, this review paper is an attempt to describe the present state of knowledge regarding the hazardous and helpful effects of Parthenium hysterophorus on people and animals.

Abstract Pteris multifida is a herbaceous fern native to temperate and tropical eastern Asia and naturalized on many continents as a result of being widely cultivated. Although it is an urban weed, it is not considered by most countries as an invasive or noxious weed. There is no information available on the species affecting native species or natural habitats. Although one source lists P. multifida as an invasive species in many countries outside of Africa due to it being easily dispersed by spores, there are no references or further information to support this statement. It is reported as an alien invasive species in Germany, but only as occurring in sheltered sites, growing on light-vents in cellars and walls. A species assessment for Florida, USA indicates, P. multifida is neither a weed of natural habitats nor of agriculture. The species has not been listed as an invasive plant in any state or natural areas of the USA. However, P. multifida has been assigned a Tier II Invasive Species status (defined as having moderate negative impacts on wildlife or natural communities in Louisiana), but of limited concern and/or extent in Louisiana. Pteris multifida is recorded in Cuba as potentially invasive being categorized as a species with a tendency to proliferate in some areas and capable of producing vast amounts of diaspores with high dispersal potential. No further details are given about potential invasiveness.

Ecosystem, which consists of the physical environment and all the living organisms, on which we all depend, is declining rapidly because of its destruction caused by humans. It’s a two-way relationship between the humans and mother nature. If we destroy the natural environment around us, human life will be seriously affected, and the life of next generation will be endangered unless serious steps are taken. One such effect of human overexploitations has come in the form of coronavirus outbreak. Coronavirus, a contagious disease of 2019 known as Covid-19, is the latest swiftly spreading global infection. The aetiology of Covid-19 is different from SARS-CoV which has the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but it has the same host receptor, human angiotensin converting enzyme 2 (ACE2). The novel coronavirus which is zoonotic (spreading from an animal to a human) and mainly found in the bats and pangolins is a single stranded ribonucleic acid virus of Coronaviridae family. 1 The typical structure of 2019-nCoV possessed ‘spike protein’ in the membrane envelope, also expressed various polyproteins, nucleoproteins and membrane protein. The S protein binds to the receptor cell of host to facilitate the entry of virus in the host. Currently four genera for coronavirus are found α-CoV, ßCoV, γ-CoV, δ-CoV. SARS-CoV first originated in Wuhan, China and has spread across the globe. World Health Organization (WHO) and public health emergency of international concern declared it as 2019 - 2020 pandemic disease.2 According to WHO report, (7th April 2020) update on this pandemic coronavirus disease, there have been more than 13,65,004 confirmed cases and 76,507 deaths across the world and these figures are rapidly increasing. Therefore, actions for proper recognition, management and its prevention must be prompted for relevant alleviation of its outspread.3 Health care professionals are mainly indulged in the national crises and are working diligently around-the-clock, small ratio of the health care workers have become affected and few died tragically. Dentists are most often the first ones to be affected because they work with patients in close proximity. On 15th March 2020, the New York Times published an article titled “The workers who face the greatest Coronavirus risk” described the dentists are highly exposed, than the paramedical staffs and general physicians, to the risk of novel coronavirus disease 19.4

The Coronavirus Disease 2019 started in Wuhan Province, China and which spread to half a dozen countries between 2019 and 2020 and was declared a pandemic. This resulted in the implementation of a lockdown in different parts of the world, explaining it was an effective and essential way to break the cycle of infection. Physical distancing is the most important measure to break this infection cycle which affected many people's lives in different aspects. Mental health is considered to be one of the important components of the overall health as the definition given by the World Health Organization. It says that the person should be well-adjusted with the environment and should not be easily upset. He should know his needs, problems and goals properly; moreover, if he faces problems, he tries to solve them intelligently for which he tries to cope up with stress and anxiety. Along with all these things, he has good self-control balances between rationality and emotionality. It has likewise set off a wide variety of mental issues, for example, anxiety, panic disorder and depression. Most of the studies have reported negative impacts, including anger, stress symptoms and confusion. Education and training on pandemic should be provided by the authorities and health care workers.

Parthenium hysterophorus L., a member of the family Asteraceae and native to subtropics of North and South America, is an invasive plant species that colonizes disturbed areas, cultivated lands, roadside vegetation, and human settlement areas. The weed has prolific seed producing ability and fast spreading in nature. The plant is rapidly infesting into tropical and subtropical regions of the world. Its occurrence in Kathmandu valley was reported first time in 1986. The seeds are highly viable and adaptive and can travel long distance with the help of its wing like structures at the base. They can anchor on rough surfaces with the help of feathered claws like structures. The weed is being very problematic because of its aggressiveness, allelopathic impacts, and health hazard risks for human and livestock. The weed posses different allelochemicals, specially sesquiterpenes and phenolics, parthenin being the chief one. The weed adversely affects crop plants and sensitive grass species. Besides it causes hay fever, dermatitis, skin infections, bronchitis and several other health impacts. The control of the weed is a challenging task; however, different herbicides and some biological agents have been reported for its management. Key words: allelochemicals; allelopathy; health hazard; Nepal; parthenin; sesquiterpene.DOI: 10.3126/botor.v6i0.2915 Botanica Orientalis - Journal of Plant Science (2009) 6: 85-92

The aim of the research has been to assay the contents of Zn, Cu, Mn, Fe, and Pb in soil and in the organs of wild Thymus serpyllum L. acquired from three natural habitats from the Kuyavia-Pomerania Province (Poland) not exposed to contamination with metals. As compared with the contents of the geochemical background of the soils in the region and the value of enrichment factor (EF), there was noted a considerable content of Pb in the soil from two locations. The Pb content in plant tissues in one of the three locations was higher than the admissible content specified by the World Health Organization WHO (above 10 mg kg−1 d.w.). As for the Zn content, only the plants from the locations with the relatively youngest phytocenosis met the conditions for herbs to be used for phytotherapy. The Zn content in the dry weight of the plants collected from the other two locations exceeded 50 mg kg−1. The risk of an elevated content of Zn and Pb in the plants makes it necessary to monitor the soil environment and to limit the collection of the plants from natural habitats, as well as to encourage the collection from controlled habitats.

Abstract:  Covid-19 has been set as a Pandemic by the World Health Organization (WHO). The very large impact and the infection that is fast enough are the reasons for making Covid-19 as a pandemic and efforts to overcome. One anticipation that can be done is to do lockdown. Making the decision to carry out a lockdown is intended to reduce the spread that occurs. Lockdown is certainly not a 100% good solution for all of individual. There are individual who agree that the lockdown will be implemented, also there are those who think that the lockdown is better not to be carried out considering the negative impacts that can occur. Therefore in this study will be presented the predictive modeling for sentiment analysis related to "lockdown" specially on social media Twitter. The method used to labeled was using Vader then the tweets are extracted using TF-IDF, and modeling is made for the prediction of sentiment using Naïve Bayes and Support Vector Machine. The results obtained from the two algorithms are more than 80%. Keywords: Covid-19, lockdown, TF-IDF, Naïve Bayes, Support Vector Machine Abstrak: Covid-19 telah ditetapkan sebagia Pandemi oleh World Health Organization (WHO). Dampak yang sangat besar dan penyebaran yang cukup cepat menjadi alsan untuk menjadikan Covid-19 sebagai Pandemi dan perlu dilakukan upaya penanggulangan. Salah satu upaya yang bisa dilakukan adalah dengan melakukan lockdown. Pengambilan keputusan untuk melakukan lockdown diperuntukan guna mengurangi penyebaran yang terjadi. Lockdown tentunya bukanlah solusi yang 100% baik bagi segala pihak. Terdapat pihak - pihak yang menyetujui akan dilaksanakannya lockdown, ada pula yang beranggapan bahwa lockdown lebih baik tidak dilaksanakan dengan pertimbangan dampak negatif yang bisa terjadi. Oleh karena itu, pada penelitian ini akan disampaikan mengenai pembuatan pemodelan prediksi terkait analisa sentimen terkait “Lockdown” yang dikhususkan pada media sosial Twitter. Metode yang digunakan adalah dengan melakukan labeling menggunakan Vader dan selanjutnya tweet tersebut dilakukan ekstraksi menggunakan TF-IDF, dan dibuatkan pemodelan untuk prediksi sentimen menggunakan Naïve Bayes dan Support Vector Machine.

  Background: Culiseta longiareolata is an important vector for many human diseases such as brucellosis, avian influen-za and West Nile encephalitis. It is likely an intermediate host of avian Plasmodium that can transmit Malta fever. The aim of this study was to determine the susceptibility level of Cs. longiareolata to different classes of imagicides which are recommended by World Health Organization . Methods: Larval stages of the Cs. longiareolata were collected from their natural habitats in Marand County at East Azerbaijan Province, northwestern of Iran in 2017. Adult susceptibility test were carried out with using impregnated papers to insecticides including DDT 4%, Cyfluthrin 0.15%, Deltamethrin 0.05%, Propoxur 0.1% and Fenitrothion 1% by standard test kits. Results: Results showed that Cs. longiareolata adult is more susceptible to pyrethroid and carbamate insecticides. Among tested insecticides, Cyfluthrin was the most toxic against Cs. longiareolata with LT50 value of 11.53 minutes and Fenitrothion had the least toxic effect (LT50: 63.39 min). Conclusions: This study provided a guideline for monitoring and evaluation of insecticide susceptibility tests against Cs. longiareolata mosquitoes for further decision making.

Abstract Background: The potential mechanisms underlying cyber victimization and the resulting psychological and physical symptoms remain unclear. Thus, the present study investigated whether Internet addiction mediates the association between peer victimization (e.g., cyberbullying) and psychological and physical symptoms. Furthermore, it was assessed whether physical exercise moderates the hypothetical mediation.Methods: 1,854 students from 11 middle and high schools in Shenzhen, Guangdong Province, China, were sampled for this study. Psychological and physical symptoms were assessed using the World Health Organization Quality of Life-BREF, while Internet addiction was evaluated using the Internet addiction test by Young. Cyber victimization was measured using a single question. In addition, this study examined whether Internet addiction mediated the association between cyber victimization and both psychological and physical symptoms. Additional work was conducted to test if physical exercise played a moderating role in the mediation hypothesized above. Mediation and moderation were analyzed using PROCESS macro for SPSS.Results: Regression analysis showed that both cyber victimization (β = -0.102, p < 0.05) and Internet addiction (β = -0.278, p < 0.05) significantly predicted psychological and physical symptoms and demographic variables were controlled. Further mediation analysis suggested that Internet addiction mediated the relationship between cyber victimization and psychological and physical symptoms. The 95% confidence interval of the direct effect was (-4.283, -1.696) and the indirect effect (­–1.904, -0.820), respectively, excluding zero. Finally, moderation analysis indicated that physical exercise moderated the relationship between Internet addiction and psychological and physical symptoms (p = 0.047).Conclusions: Internet addiction plays a mediating role in the association between cyber victimization and both psychological and physical symptoms, Thus, addressing Internet addiction among cyberbullying victims is worthwhile. Furthermore, physical exercise alleviates negative impacts on health and should thus be promoted.
