Some composts can produce phytotoxins that inhibit the development of plants and the absorption of nutrients by an excess of indoleacetic acid if the compost is not mature. In the present work, the objective is to evaluate the quality of the compost by means of direct tests of phytotoxicity and agronomic quality with different composts. To determine the quality as organic compost and vermicompost fertilizer were considered physical, chemical and biological variables according to existing manuals. The results obtained for these variables were: In the physical, chemical and biological variables, all the parameters are fulfilled according to the norm. Seed germination of vegetables increased with respect to the control in 14.93%, possibly due to the presence of some root development promoter found in the compost. With regard to survival the witness was inferior by 3.08% Although the amount of nutrients found in composts are not so high, they comply with the minimum requirements of the regulations to be used as a substrate in horticultural applications. Conclusion, the results of this study indicate that the compost elaborated with any type of residue can be used as a substrate in seedbeds of chili, onion or other vegetables to induce germination and accelerate the development of plants.

Urban trees positively influence the quality of life in cities, but they need to be pruned regularly, generating a large amount of solid urban waste. This study aimed to compost urban pruning waste, evaluate its physical, chemical, structural characteristics, and determine its potential as a substrate to produce forest seedlings. The pruning residue was obtained from the Rio de Janeiro Municipal Cleaning Company (COMLURB) - Brazil. Twigs and leaves ≤ 8 cm in diameter were chopped and arranged on a trapezoidal windrow. Temperature, humidity, and aeration were controlled throughout the composting process. Irrigation and turning were carried out as needed. The composting process took 122 days. The compost was dried, processed, and evaluated for physical and chemical characteristics. The leachate was collected and characterized by 13C CP MAS NMR. The temperature patterns were consistent with the thermophilic, mesophilic, and maturation stages. Part of the chemical and physical characteristics of the compound was classified as adequate, according to the literature. The leachate contained large amounts of C alkyl and low amounts of C carbonyl at all times of composting. The characteristics determined indicated that the composting process was interrupted before complete maturation was achieved. However, the compound can be combined with other materials to produce a complete substrate.

A quality drug is central to the success of any therapeutic plan. The quality of drug is determined right from the collection to delivery to the patients. The commonest problem involving the medicinal plant stating materials is intentional or unintentional substitution and adulteration owing to multiple reasons like unavailability, higher costs, unfair trade etc. This trend was also present in the olden days, as evident from the concept of substitute drugs (Pratinidhi Dravya) as available in Yogratanakara, Bhavaprakasha and Bhaishajyaratnawali. Therefore, Charka and later Acharyas also have dealt with authentication and standardization of herbal drugs and formulations in detail by using four Pramanas (tools of knowledge) Ch.Vi.8/87. Nowadays the concept of substitution is entirely converted into intentional and unintentional malpractices of adulteration. The established authenticity parameters for plant material identification and standardization like organoleptic, physical, chemical and genetic parameters are relatively inaccessible for routine use. Not withstanding the accuracy and usefulness of these lab parameters and delay in the development of easy to perform parameters for reasonable drug authentication. These adulteration malpractices spoils the market of herbal industries. In this article we discuss about concept of substitution in ancient Ayurveda and at present intentional and unintentional adulteration practices.

Systems of weed control composed of (a) herbicides only, (b) herbicides plus cultivation, or (c) cultivation only were devised. The most effective systems, involving herbicide sequences plus one “non-dirting” layby cultivation, controlled twelve troublesome species of weeds with acceptable yields of peanuts (Arachis hypogaea L.). On Greenville sandy clay loam, a particularly effective and economical system of weed control consisted of (a) N-butyl-N-ethyl-α,α,α-trifluoro-2,6-dinitro-p-toluidine (benefin) used as a preplanting incorporated treatment, then (b) S-propyl dipropylthiocarbamate (vernolate) either incorporated into the soil before planting or injected at planting, and finally, (c) a layby cultivation 5 to 6 weeks after planting. A similarly effective system on Tifton loamy sand involved vernolate injected at planting, 2-sec-butyl-4,6-dinitrophenol (dinoseb) at “cracking”, and 4-(2,4-dichlorophenoxy)butyric acid (2,4-DB) as a postemergence treatment followed by the layby cultivation. The “non-dirting” layby cultivation, averaged over both years and herbicide sequences, significantly increased yields of peanuts on both soil types. None of the systems of weed control caused consistent differences in market grade, average weight per seed, germination, or organoleptic quality of the peanuts.

<span style="font-family: Times New Roman; font-size: small;"> </span><p>Four formulations of chicken burger were prepared: control product without inulin, and products with 1.0, 2.0 or 3.0 % of inulin (in relation to the weight of meat, fatty raw material, and water), respectively. Physical, chemical and sensory analyses were made to evaluate the effect of inulin on the quality of cooked burgers. The results showed that the application of inulin did not cause significant decrease of the thermal processing yield nor the shear force of the products. However, the addition of inulin resulted in slight, but significant differences (P &lt; 0.05) in chemical composition and energy value of burgers. Burgers of all formulations were acceptable in sensory characteristics. The addition level of inulin not higher than 1.0 %, did not result in deterioration of physical, chemical and sensory quality characteristics of chicken burgers. To improve the nutritional value of chicken burgers, the modification of fatty acid composition is recommended.</p><span style="font-family: Times New Roman; font-size: small;"> </span>

El presente artículo está enfocado hacia el Estudio del Arte de Calidad de Vida desde el área de la Salud, específicamente tomando en cuenta las investigaciones realizadas con niños(as) y adolescentes en cáncer y su Calidad de Vida; para ello se realizó una revisión de los últimos diez años, después de un arqueo bibliográfico se consideraron aproximadamente 80 artículos para su revisión y discusión. De acuerdo a la revisión realizada se enfocó en tres aspectos: a) Elementos conceptuales relacionados con la Calidad de Vida(CV) y la Calidad de Vida relacionada con Salud (CVRS); b) la medición de la CVRS específicamente en niños(as) y adolescentes y c) Los diferentes instrumentos de evaluación creados para medir la CVRS en niños(as) y adolescentes. En relación con el primer aspecto, este constructo ha sido más fácil medirlo que definirlo, es un concepto extenso y ambiguo. En relación con la medición, uno de los problemas es el relacionado con las dificultades inherentes a su evaluación, debido a la naturaleza bipolar objetiva-subjetiva y su multidimensionalidad, compleja e indeterminada, y esto le da a la evaluación un problema adicional, aunado también que los instrumentos elaborados para tal fin, en ocasiones no cumplen los requisitos mínimos de construcción y generalización de resultados. La mayoría de las investigaciones concluyen que es muy importante la evaluación de la CVRS en el paciente pediátrico con cáncer, ya que la sola presencia de una enfermedad crónica desestabiliza la emocionalidad del paciente. Se concluye la importancia de la medida de CVRS en pacientes pediátricos, para uso en la práctica clínica y en la salud pública, considerar el proceso de crecimiento y desarrollo físico, cognitivo, intelectual y afectivo del niño/a ya que es continuo y representa un reto captar los aspectos positivos y los que afectan negativamente en la calidad de vida del paciente. The present article is focused towards the study of the art of quality of life from the area of the health, specifically taking in has them research made with children (as) and adolescents in cancer and its quality of life; for this is performed a review of them last ten years, after a tonnage bibliographic is considered approximately 80 articles for your review and discussion. In accordance the review focused on three aspects: to) conceptual elements related to quality of life (HP) and the quality of life related with health (HRQOL); b) the measurement of HRQOL in children and adolescents and c specifically) the different assessment instruments designed to measure HRQOL in children and adolescents. Regarding the first aspect, this construct has been easier to measure it to define it, is a lengthy and ambiguous concept. In relation to the measurement, one of the problems is related to the difficulties inherent in their assessment, due to the bipolar nature and its multidimensionality, complex and indeterminate, and this gives the assessment an additional problem, also joined that elaborate instruments for that purpose, sometimes do not meet the minimum requirements of construction and generalizability of results. The majority of the investigations conclude that assessment of HRQL in pediatric cancer patients is very important since the mere presence of a chronic disease disrupts the emotionality of the patient. Is concludes the importance of the measure of HRQOL in patients Pediatric, for use in the practice clinical and in the health public, consider the process of growth and development physical, cognitive, intellectual and affective of the child / to since is continuous and represents a challenge capture them aspects positive and which affect negatively in the quality of life of the patient.

Flow regulation is one of the most common anthropogenic factors affecting rivers worldwide. In Korea, 16 weirs were constructed along four major rivers from 2009 to 2012. This study aimed to elucidate initial changes in physical, chemical, and biological variables after the construction of consecutive weirs on the Nakdong River, a major large river system. Water quality variables and phytoplankton cell densities were investigated at eight representative sites and compared with the data recorded before the weir construction. There were spatial and temporal changes in the hydraulic retention time (HRT), total phosphorus (TP), and chlorophyll a concentrations among the eight weir sections. HRT increased after the weir construction, while TP and chlorophyll a tended to decrease from the middle to lower section of the Nakdong River. Furthermore, differences were observed in the phytoplankton community composition between 2006–2007 and 2013. There was a marginal decrease in the duration of centric diatom (Stephanodiscus hantzschii) blooms after weir construction. However, Microcystis aeruginosa proliferated more extensively during summer and autumn than it did before the weir construction. Our results suggest that changes in hydrological factors, in response to consecutive weir construction, may contribute to greater physical, chemical, and ecological variability.
