Marsilea minuta is a very common leaf vegetable to the people in west Bengal. The common name in Bengali of this pteridophytic plant is “Sushni sak”. It grows in tropical humid climate in all classes of soil round the year except the winter months. It has good medicinal potentiality as well as nutrient components. Though it grows in marshy fallow land in neglected conditions, but it could gain valuable leafy vegetable considering its nutrition quality as well as palatability. But indeed it is not freshly available in the market round the year.

Solar radiation is a very important meteorological component of the hydrological, energetic, architectonic and agro environmental processes. However, the instruments that are responsible for their measurement have a high cost of acquest and maintenance. Therefore, empirical models have been developed for estimating the solar radiation and then, reducing costs.

Food insecurity is becoming an issue both nationally and internationally due to rapid population growth. One way to deal with this problem is to improve soil fertility using organic fertilizers in order to increase soil productivity in a sustainable way, thus rise crop yield and feed the growing population. Compost is one of the proposed suitable organic fertilizers increasing soil nutrients in a regular basis.

HD-ZIP proteins are a class of transcription factors family that have a conserved homeodomain in all of its factors. Homeo box; conserved part of home domain consists of 56 amino acids residues and involved in plant development from formation pattern to specification into different cell types. We retrieved the protein sequence of all the 48 transcription factors of HD-ZIP family and performed genome wide analysis and grouped them into four subfamilies.

The current study focused on GC-MS analysis for identification of bioactive compounds in leaf extract of mangrove plant, Acanthus ilicifolius leaf extract was tested for cytotoxicity against MCF-7 cell lines. The spectral properties (GC-MS) of each separated compound were determined and found the different compounds namely aziridine, alcohols, phenolic and fatty acid compounds. GC-MS analysis proved that the leaf extract of Acanthus ilicifolius contain a high content of ethanol compounds.

O mercado mundial de flores e plantas ornamentais encontra-se em plena fase de expansão. A floricultura brasileira vem adquirindo notável desenvolvimento e se caracteriza como um dos mais promissores segmentos da horticultura intensiva no contexto do agronegócio nacional. Com o propósito de melhorar a qualidade das flores, o presente estudo teve como objetivo avaliar a influência da aplicação de diferentes concentrações de potássio e magnésio no desenvolvimento de plantas de crisântemo (Dendranthema grandiflora, Tzevelev.) cultivados em vasos.

This study aimed to analyze the health and environment aspects of the rural area that influence the quality of health in Teresina, Piaui, Brazil. This study was characterized as a reflective descriptive research of direct observation experience report. The participant observation study was conducted by health professionals who work in the primary health care of the Family Health Strategy within the community and carry out research studies in the rural area. The participant observation period was held in 2018, with various activities within the community.

Objective: This study aimed to know the conditioning factors of the transition process to the self-care of women diagnosed with HIV/AIDS. Method: This qualitative study was carried out from June to September 2015 with seven seropositive women, users of a specialized service in sexually transmitted diseases in the municipality of Imperatriz, Maranhão State, Brazil. For the data collection, an individual interview was used, and data analysis was performed by content analysis.

The objective of this work was to evaluate physiological changes related to deterioration of sweet potato roots cv. BRS Cuia during storage at room temperature, identifying the major problem during postharvest. It was determined weight loss, sprouts number, sprouts length, water potential, peroxidase and polyphenoloxidase enzymes activities, and fraction of soluble phenols. The evaluated variables showed increases, except for skin fraction of soluble phenols that decreased during storage.

The search for yeast with proteolytic activity that can be explored in technology and product innovation was the objective of this study to isolate and identify strains present in liquid whey and evaluate the proteolytic activity of isolates. From the isolated strains were selected for molecular identification, those with proteolytic activity. Verification of proteolytic activity was performed on milk agar and visualized by a translucent halo. Four strains belonging to two yeast species were identified as protease producers.
