Abstract The paper presents the results of compost tests from home composters and earthworms living there, that treating waste into compost. The samples were taken from home composters and allotment gardens from Opole Region. The composting material was green waste. The total content of heavy metals (Cd, Pb, Cu, Zn, Ni Cr) in compost and compost earthworms’ samples were determined. It was found that the compost samples were not contaminated with heavy metals. According to the Polish classification of composts from municipal wastes, the composts met the requirements for first class of quality. The composts did not exceed the limits of heavy metals specified in the Polish law for solid organic fertilizers. The degree of metal accumulation by compost earthworms depended on the type of metal. The high value of the bioaccumulation factor (BAF) was obtained for Cd, Pb and Zn. No accumulation of other metals (Ni, Cr, Cu) in earthworm bodies was found. It has been found that earthworm species, naturally occurring in Poland, can also be used as potential bioindicators of metals in the environment, such as the species Eisenia fetida. The aim of the study was to evaluate the heavy metal content in composts from home composters and ability to accumulate metals by compost earthworms.

Composting is the most widely used biological treatment method for recovering the plant nutrients of organic waste. Composting is an aerobic process and it is well known that mismanagement, e.g. insufficient ventilation, can seriously affect the turnover and performance of the process. The turnover is also strongly inhibited if the operation temperature rises above 40°C before the pH has increased above 6. Such a combination of high temperature and low pH also seriously increases the odour emission potential of the compost operation as the initial high odorous stage is prolonged until the pH increases. When the pH increases beyond 6.5, the odour potential rapidly decreases. The pH development can be accelerated by good cooling and ventilation, and/or by addition of alkaline amendment, e.g. recycling of alkaline compost or addition of wood ash. When the compost is turned, the structure of the compost matrix, and thus the aeration, is improved which decreases odour generation and also the proportion of anaerobic processes and thus the emissions of methane.Studies of food waste home composts show that these have a much higher moisture content (70-80%) compared to what is normally recommended for composting (40-65%). The common assumption has therefore been that methane emissions from home composts are greater than from large scale municipal composts. However, recent studies in both Sweden and Denmark show that the methane emissions from home composts usually are smaller than from large municipal composts. Furthermore, both studies indicate that the emissions seem to increase if the composts are frequently turned, quite contrary to what was expected. The emissions also seem to increase if the feeding is too high. This means that the capacity of the home compost should not be exceeded and that the efforts for its operation can be kept low, as turning does not seem to be an advantage, at least from the point of view of greenhouse gas emissions.

The use and quality analysis of household compost have become very important issues in recent years due to the increasing interest in local food production and safe, self-produced food. The phenomenon was further exacerbated by the COVID-19 pandemic quarantine period, which gave new impetus to the growth of small home gardens. However, the knowledge associated with making high-quality compost is often lacking in home gardeners. Therefore, the objective of this research was to find answers to the following questions: can the quality of backyard compost be considered safe in terms of toxicity and nutrient content? Can weed seed dispersion affect the usability of backyard compost? In general, can the circulation of organic matter be increased with the spread of home composting? In this study, 16 different house composts were analysed for stability, weed seed contamination, toxic elements, and nutrient content using analysis of variance. The results of the research showed that the quality properties of the composts (including their weed seed dispersion effect) were greatly influenced by the different techniques and raw materials used. The toxicity levels, as well as the content of macro and microelements, were within the parameters of safe-quality compost. The specific macronutrient (Ca, Mg) and micronutrient (Fe, Mn) contents of the tested composts have a similar and, in some cases, more favorable nutrient supply capacity in crop production than the frequently-used cow manure-based composts. With a plan of basic education on composting, there is potential to encourage farmyard composting.

Depending on the materials used to produce a compost, it will contain lower or higher levels of nutrients and metals. If composts have been appropriately matured, nutrients are in plant-available forms for crop production, and the compost pH will be near neutral. After 25 years of research and development of regulations and advice for biosolids and compost utilization, pretreatment of industrial wastes allows biosolids composts, and composts prepared from biosolids mixed with municipal solid wastes or yard debris to contain levels of microelements needed for plant nutrition but not high levels that could cause phytotoxicity. Composts can supply N, P, K, Ca, Mg, Fe, Zn, Cu, Mn, B, Mo, and Se required by plants or animals. When used in potting media, supplemental N fertilization is usually required, depending on crop requirements. Use of compost can replace other forms of microelements used as fertilizers in media or fields. Detailed evaluation of potential food chain transfer of Cd, Pb, and other elements in composts clearly shows that consumption of 60% of garden foods produced on pH 5.5 soils with 1000 t compost/ha would not comprise risk over a lifetime of consumption, nor would ingesting the composts at 200 mg/day for 5 years. Potentially toxic organic compounds are either destroyed during composting, or bound very strongly by the compost so that plant uptake is trivial. Compost use can be a safe and wise choice for both home and commercial use to replace peat or uncomposted manures, etc. Many states have developed regulatory controls to assure that pathogenic organisms are killed during composting, and that product quality standards are attained that allow marketing for general use in the community.

One of the principles of the circular economy requires the effective recycling of organic waste, especially since its volume is increasing from year to year. Therefore, one of the best solutions to solve this problem is the composting of organic waste. This paper presents the results of a comparative study of 10 different composts in terms of their quality. The composts varied with regard to waste materials used for composting, the adopted composting method, and the degree of compost maturity. Both biological (seed germination rate and intensity of plant root growth) and chemical methods (contents of macro- and micronutrients, presence of heavy metals, as well as the quality and quantity of humus compounds) were applied to evaluate the fertilisers, providing comprehensive characteristics of individual composts. It was found that composts prepared on the basis of sewage sludge had the highest contents of macro- and micronutrients as well as heavy metals. In addition, these composts contained the greatest amounts of humic substances, although these were of low quality. These composts also strongly inhibited seed germination and plant root growth. The least desirable chemical composition was found for the composts based on yard trimmings and household wastes prepared in home composters. These composts contained good quality humus compounds and had a positive effect on seed germination and plant root growth.

A field study was conducted in 2010 and 2011 to determine the suitability of Earth-Kind® production principles for home vegetable gardening. Earth-Kind® production encourages water and energy conservation, and reduction of fertilizer and pesticide use. Seven vegetable cultivars [Sweet Banana and bell pepper (Capsicum annuum); Celebrity and Juliet tomato (Solanum lycopersicum); Spacemaster cucumber (Cucumis sativus); Ichiban eggplant (Solanum melongena); Spineless Beauty zucchini (Cucurbita pepo)] were grown in mushroom compost (MC) or city compost (CC). Both composts were incorporated preplant into the soil with shredded wood mulch placed over them. In each year, nitrogen (N) fertilizer (15.5N–0P–0K from calcium nitrate) was applied preplant to CC plots to bring initial soil fertility levels similar to MC plots. No additional fertilizer was applied during the growing season. Drip irrigation was supplemented weekly. One application each of neem oil and pyrethrin (organic insecticides) and chlorothalonil (synthetic fungicide) was applied before harvest in 2010, but none was applied in 2011. Results indicated that Earth-Kind® technique could be effectively implemented in a home vegetable garden. MC is better suited for Earth-Kind® vegetable production than CC for some vegetables. Banana pepper, bell pepper, and zucchini had twice the yield in MC plots when compared with CC plots. No yield differences (P > 0.05) were observed between composts for tomato, eggplant, or cucumber. With proper irrigation and soil preparation practices such as addition of compost and mulch, Earth-Kind® vegetable gardening techniques can be used for selected vegetable crops without additional N fertilizer or pesticides. Furthermore, Earth-Kind® vegetable gardening can be successful as long as the home gardener understands that low yields may result from using this production method. However, often the home gardener is more concerned about producing vegetables using sustainable, environmentally friendly methods than maximizing yields.

In developing countries like Pakistan the organic waste production is comparatively high. Composting is a good option to overcome problems related to management of organic waste. Compost produced from solid waste should be according to the standards set for soil to ensure beneficial results in plants. The objectives of the study were to determine the quality of compost used in agricultural lands in different areas of country.In the study area the commercially available compost is prepared by windrow composting method. Some home gardeners prepare compost by invessel method. But the sale of commercial compost decreased with the passage of time. One of the reasons behind this includes low quality compost and less desired results in terms of soil fertility. Comparative analysis of windrow compost sample and in-vessel compost samples were carried out to identify the fate of these composts in terms of international standards. Analysis results revealed that some parameters were lower than standard values i.e. moisture content was less than 45% in all samples, carbon nitrogen (C:N) ratio was less than 25 which should be >25, available carbon was < 35% in all samples and burned carbon was also <35% in all samples. Compost is used as a soil conditioner and low level fertilizer however if its nutritional value is not according to the standard it maybe no longer beneficial for plants. Substandard compost can also cause microbial degradation in soil and can make it anaerobic as well.

One way to improve compost quality of typical organic waste is by addition of additive such as wood chips. This study aims to analyze the impact of the wood chips addition (ratio 1:10) on compost quality of typical organic waste (fruits, vegetables, yard waste, and food waste) in home composter, and to compare the compost quality with the standard of domestic compost according SNI 19-7030-2004. Analysis was conducted on composts raw material, compost maturity process in every 5 days measurement, and on compost product. Analysis of compost product of typical organic waste with addition of wood chips showed that parameters of temperature, moisture content, and pH of vegetables and yard waste has complied the standard whilst parameter of C/N ratio has not complied. The addition of wood chips caused the drop of compost temperature and moisture content, resulted in the decomposition process located in aerobic condition, resulted in production of compost in form of humus in greater volume. The addition of wood chips also caused the compost pH and C/N ratio increased.Keywords: compost quality, home composter, typical organic waste, wood chipsAbstrakSalah satu upaya untuk memperbaiki kualitas kompos sampah organik adalah dengan penambahan bahan aditif, seperti serpihan kayu. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan serpihan kayu (perbandingan 1:10) terhadap kualitas kompos sampah organik sejenis (buahan, sayuran, halaman dan sisa makanan) dalam komposter rumah tangga dan membandingkan kualitas akhir kompos ini dengan kualitas kompos sampah domestik menurut SNI 19-7030-2004. Analisis dilakukan terhadap bahan dasar kompos, proses kematangan dengan pengukuran setiap lima hari sekali, dan kualitas akhir kompos. Dari analisis akhir kualitas kompos sampah organik sejenis dengan penambahan serpihan kayu, parameter yang telah memenuhi standar adalah temperatur, kelembapan, pH untuk sampah sayuran dan sampah halaman, sedangkan untuk parameter rasio C/N belum memenuhi standar. Penambahan serpihan kayu menyebabkan temperatur dan kelembaban kompos menurun, sehingga proses dekomposisi berada pada suasana aerobik, yang menghasilkan kompos dalam bentuk humus dengan volume yang lebih banyak. Penambahan serpihan kayu juga meningkatkan pH dan rasio C/N kompos. Kata kunci: komposter rumah tangga, kualitas kompos, sampah organik sejenis, serpihan kayu

De multiples foyers maraîchers sont dominés par l’emploi des fertilisants organiques de source animale pour relever le niveau de fertilité des sols. L’objectif de cette étude était de comparer l’effet de deux types de composts sur la performance agroéconomique de l’amarante (Amaranthus cruentus L) dans les jardins familiaux au sud du Bénin. Un dispositif en split plot à deux facteurs et quatre répétitions a été utilisé. Le premier facteur était le type de compost à deux variantes (compost à base de fiente de volaille et compost à base de bouse de vache) et le second facteur était la dose (0 ; 20 ; 30 et 40 t.ha-1). Les effets de ces deux facteurs ont été évalués par rapport au nombre de feuilles, la hauteur, le diamètre au collet, le rendement à la première et deuxième coupe ainsi que la biomasse totale de l’amarante. Sous la dose de 30t.ha-1, la fiente de volaille compostée a amélioré significativement (p < 0,001) le rendement de l’amarante (30,8 t.ha-1) avec un gain élevé et un indice d’acceptabilité ≥ 2 comparativement à la bouse de vache compostée (19,2 t.ha-1).Une dose de 30 t.ha-1de fiente de volaille compostée pourrait être recommandée aux maraîchers pour une meilleure productivité de l’amarante au Bénin.
Many market gardens are dominated by the use of organic fertilizers from animal sources in order to raise the level of soil fertility. The objective of this study was to compare the effect of two types of compost on the agronomic and economic performance of amaranth (Amaranthus cruentus L) in home gardens in southern Benin. A two-factor split plot device with four repetitions was used. The first factor was the type of two-variant compost (compost made from poultry manure and compost from cow dung) and the second factor was the dose (0; 20; 30 and 40t.ha-1). The effects of these two factors were tested on the number of leaves, the height, the diameter at the neck, the yield at the first and second cut as well as the total biomass in dry matter of amaranth. Under the dose of 30t.ha-1, composted poultry manure significantly improved the yield of amaranth (30.8 t.ha-1) with a high gain and an index of acceptability ≥ 2 compared to composted cow dung (19.2 t.ha-1). A dose of 30t.ha-1 of composted poultry manure could be recommended to market gardeners for better productivity of amaranth in Benin.

This study motivates farmers to use an online business stage to shape their income without any middlemen. Online business is one of the quick enterprises on the planet. Numerous organizations were at that point moved to online business and producing immense income inside a brief timeframe. The serious issue is "The farmer who produces nourishment for the country isn't benefitting with the pay". Since there is no such committed stage for farmers to create beneficial pay for their developed items. Existing stages are joined with all classifications (home, kitchen, and electrical apparatuses) of items that could tangle up farmers, and furthermore, the absence of app information is one reason that a farmer will be unable to sell their items on the app. To defeat this, The Bhaaratha Vivasayi app will be useful where a farmer can be ready to sell or buy anything connected with the agribusiness and cultivating classification without middlemen. A basic easy to understand app with numerous rancher merchants and different horticultural items alongside a point-by-point review about the most recent cultivating innovations will definitely shape the cultivating area income. This will help ranchers to get information and save both time and energy. Likewise, new associations and correspondences will be laid out and the item stock will sell effectively with practically no work help. Also, it will help customers to buy organic fresh groceries at a reasonable price directly from farmers. Basically, It is devoted to farmers with all cultivating items like pesticides, seeds, composts, crops, etc. . So, this app will surely play a vital role in uplifting & benefitting framers as well as customers.

Biosolids are municipal wastewater treatment solids that meet regulatory standards for land application. Most biosolids are a rich source of N, P, and micronutrients. Although the use of biosolids on food crops remains controversial in the public eye, decades of research have led to the development of regulations for the safe and beneficial use of biosolids in agriculture. Emerging areas of research include biosolids in commercial and home horticulture, the fate of pathogens and organics in biosolids, the use of biosolids in the remediation of contaminated sites, and biosolids effects on soil ecology. Nutrient management remains the most critical day-to-day issue for land application of biosolids. Recent research on plant-available nitrogen (PAN) in biosolids has found that N availability is similar over a range of biosolids processing types, and that growing-season climate is a key factor affecting available N. Regionally based predictions of PAN have been developed for the United States, and could be extended into Canada. Relatively little is known about the effects of biosolids applications on soil ecology, but soil nematodes offer an opportunity to evaluate the structure and function of the soil ecosystem following biosolids applications. We have studied responses of nematode communities to application of municipal biosolids and composts, in forage production systems and orchards. Both types of amendments increased the abundance of enrichment opportunists, for up to 3 yr after single applications. These data on the persistence of increased enrichment opportunists have provided insight into the longevity of amendment-induced enhancement of biological activity and nutrient cycling. Cumulative biosolids applications of 90 Mg ha-1 have caused reductions in abundance of pollutant-sensitive Dorylaimida. The extent to which this change is the result of metal or nutrient loading is unclear and deserves more detailed study. Key words: Biosolids, plant-available nitrogen, soil ecology, nematodes

“Portraît de Nadia Boulanger”, para voz e piano, foi composta em 1972 por Almeida Prado (1943-2010) como uma homenagem à sua professora durante o período de aperfeiçoamento na França, que durou de 1969 a 1973. O presente artigo objetiva analisar musicalmente esta peça. Como metodologia, cada um dos dez movimentos será analisado separadamente, buscando desvendar as suas características próprias. Como resultado final, percebe-se que, embora os movimentos tenham sido compostos com técnicas e materiais musicais diversos, há elementos que os conectam, tais como o uso de um mesmo material harmônico; a estruturação por rotações de uma série dodecafônica; a exploração de material sonoro/musical com ênfase nas ressonâncias e timbres, dentre outros. A relevância deste artigo ocorre pois, pelo período em que foi escrita a peça, é possível perceber a transitoriedade nas técnicas composicionais de Almeida Prado e, desse modo, contribuir para o melhor entendimento de seu desenvolvimento estilístico como compositor.

A grande procura por parte de profissionais e pacientes por restaurações dentarias estéticas, levou à grandes evoluções na composição das resinas compostas. Alguns compósitos apresentam excelentes propriedades mecânicas e ópticas, mimetizando características importantes do elemento dentário com muita naturalidade. No entanto, a confecção de restaurações de excelência em resina composta não se resume apenas na escolha de qual resina utilizar em cada caso. É extremamente importante que sejam realizados todos os procedimentos necessários para a confecção e correta finalização das restaurações em resina. Entre estes encontram-se as etapas de acabamento e polimento as quais são importantes para a estética, longevidade da restauração e saúde periodontal do paciente. No entanto, essa etapa é negligenciada por alguns profissionais. Este trabalho tem como objetivo descrever vantagens e desvantagens das resinas compostas disponíveis no mercado e demonstrar a importância do acabamento e polimento em restaurações de resina composta, apresentando algumas das opções disponíveis hoje no mercado atual. Foi realizada uma revisão da literatura narrativa descritiva a respeito do tema proposto, utilizando-se como base bibliográfica artigos científicos publicados no período de 2003 a 2021, disponíveis nos bancos de dados online BVSalud, PubMed, Scielo, Lilac e Google Acadêmico, disponíveis nas línguas portuguesa e inglesa. Ao final deste trabalho concluiu-se que é extremamente importante que os cirurgiões dentistas tomem ciência da importância da realização dos procedimentos de acabamento e polimento para melhorar a qualidade de suas restaurações diretas em resinas compostas.

No crescimento e desenvolvimento de uma criança, vemos espelhada a evolução filogenética do homem. Ao tornar-se bípede e adquirir a posição ereta, o homem passou por transformações musculoesqueléticas das quais a mais marcante é a transformação da cifose única da coluna vertebral (CV) em uma curva tipo “S” no plano sagital, presente no homem adulto. Se por um lado a postura ereta liberou as mãos para atividades de maior precisão, ela criou novas possibilidades de conflitos mecânicos, os quais, em determinados indivíduos e em determinadas situações, podem conduzir às doenças chamadas de origem mecânico-posturais. A unidade funcional da CV é composta por dois segmentos: o anterior, contendo dois corpos vertebrais, separados por um disco; e o segmento posterior, funcionalmente composto por duas articulações zigoapofisárias ou interfacetárias. O segmento anterior é uma estrutura de sustentação, suporte de peso e amortecedora de choques, enquanto o segmento posterior normalmente não suporta peso e tem por função principal a de guia direcional dos movimentos.

Currently in Cisauk area, there are still a lot of trashes lying on the streets, ditches, rivers, and other public places. The government has encouraged all citizens to sort out garbage and process organic waste into compost. However, not many people comply with this encouragement due to their ignorance or lack of knowledge about practical composting methods. This study aimed to improve social awareness in managing and processing organic domestic waste into compost using Takakura home composting method, which is easy, inexpensive, and odorless. Moreover, different home-made compost starters with different mixed microbial inoculants were compared. The study included microbial inoculant preparation, home-made compost starter production from rice husk and rice bran, and compost production in Takakura basket. The methods were taught through a series of workshop in Bermis Serpong Asri Residence, Cisauk, Tangerang. Through this effort, the problem of domestic organic waste was expected to be overcome. Moreover, the product of Takakura home composting can be used as plant and soil fertilizer, or even sold to increase family income.

The composition of organic waste reaches 59% of the total municipal solid waste in Indonesia. One way to process organic waste is composting by utilizing microorganisms to break down waste into compost. Naturally, the composting process took a long time but can be accelerated by adding microorganisms to the activator. This study analyzes the quality and quantity of compost using the Biopore Infiltration Hole (BIH) method with activator addition. Composting was duplicated in the yard area with clay soil type and water infiltration rate of 0,3 cm/hour. The BIH was made in a 10 cm diameter, a 100 cm depth, and the distance between the holes was 50 cm. Composting variations consist of variations in the composition of the raw materials and the activators' uses. Variations in the raw material composition consisted of 100% yard waste, 100% food waste, 50% yard waste and 50% food waste, and 70% food waste and 30% yard waste. In contrast, the activator variations consisted of no activator, EM4 activator, and Stardec activator. Compost analysis consists of maturity, quality of physical and macro elements, and quantity of compost. The results showed that all variations of composting had met the standard of maturity and quality of physical and macro elements according to SNI 19-7030-2004. The addition of activator affected composting time and compost quantity. The composting time in BIH with activator ranges from 41-60 days. In BIH without activator ranges from 65-75 days, there was a reduction in composting time by 15-25 days with the activator addition. However, the activator addition caused reducing the compost quantity by 10-20%. The selection of compost variations by scoring results in compost with a composition of 50% yard waste and 50% food waste and the addition of Stardec activators was the best variation in terms of compost maturity, quality, and quantity.

A indústria busca constantemente inovar e lançar no mercado novos produtos que atraiam o consumidor. Nesse contexto, foi lançado o composto lácteo, um produto com a mistura de pelo menos 51% de base láctea (leite ou derivados) com outros produtos alimentícios que, segundo os próprios fabricantes, é voltado para crianças de um ano até a idade pré-escolar. Existem no mercado brasileiro 13 tipos diferentes de compostos lácteos. A semelhança entre as embalagens pode causar confusão na compra por parte dos cuidadores, que podem achar que esses compostos são substitutos, equivalentes ou seguimento das fórmulas infantis, a um custo reduzido. Eles costumam ser promovidos comercialmente com brindes e descontos em compras múltiplas ou combos, além de serem intensamente promovidos em mídias sociais. Os rótulos deles valorizam o fato de conterem óleos essenciais, fibras, imunonutrientes, vitaminas e minerais, o que pode induzir o consumidor a pensar que o produto fornece, sozinho, tudo que a criança precisa nesta faixa etária, apesar de ser um produto ultraprocessado, não recomendado para o consumo dessa criança. Por serem produtos novos no mercado, ainda não se enquadram na Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeiras, hoje Lei nº 11.265/2006 e Decreto nº 9.579/2018. Sugere-se a inclusão do composto na legislação, com a comercialização controlada no escopo da lei, bem como a criação de normas para restringir a publicidade abusiva deste e outros produtos para crianças entre um e três anos de idade.DOI: 10.12957/demetra.2019.43609

Home composting is judged as an effective municipal waste management option in which household contribution is essential, but it has a low adoption. The objectives of the study were to determine the factors that influence home composting intention and identify the moderating role of composting knowledge in the model, using the combined model of the theory of planned behavior (TPB) and norm activation model (NAM). A structured questionnaire was applied to a sample of 367 residents of Isfahan city, Iran, randomly selected. Data were analyzed using cluster analysis, discriminant analysis, PLS-SEM, and PLS-MGA. Cluster analysis grouped the three clusters based on the constructs of the integrated model, and this result was confirmed by discriminant analysis. Findings show that attitude, subjective norm, and perceived behavior control can predict the intention to compost. Study results confirmed the positive effect of awareness of the consequences of composting on ascribed responsibility to compost at home, of responsibility to the personal norm, and of the personal norm on intention to compost at home. Furthermore, it was observed that composting knowledge moderates the relationship between subjective norm and behavioral intention, and the one between perceived behavioral control and behavioral intention. The integrated model had more predictive power than the TPB model. The fit statistic of the integrated model was good and 71% of the variance for intention behavior toward home composting. The insights on factors affecting residents’ intention to compost obtained from this study can be used in measures and programs that reinforce and stimulate home composting.

Resumo: Neste artigo, recusa-se o frequente pessimismo de Freud, tantas vezes denunciado por seus leitores, em relação à vida dos homens e aos destinos da humanidade, recusa auxiliada pela distinção, em sua obra, entre o domínio da metapsicologia e o da clínica. O primeiro domínio, fortemente associado à sistematização da psicanálise, admite um determinismo naturalista que, em seus termos, não prevê a autodeterminação do homem, da civilização e seus destinos, isto é, não tem a liberdade como uma noção operatória, caso em que as especulações teóricas foram compostas por certo ponto de vista evolucionista, partilhado com a biologia, assim como pelo ponto de vista entrópico, partilhado com a física. Sustenta-se que a metapsicologia foi assim concebida na ordem dos princípios que orientam a evolução de cada homem e da humanidade, segundo uma finalidade que comporta sua própria exaustão, por isso é aqui denominada entrópico-declinista. O segundo domínio, relacionado ao diagnóstico e às técnicas de cura, comporta uma noção de homem e de civilização que, longe de ser resultado de uma providência natural ou sobrenatural, o é de si mesmo, caso em que admite um tipo de autoesclarecimento, de escolhas e mesmo de autorregulação visando, no limite, à autoprodução humana que permite postergar o destino entrópico da humanidade, que neste texto se nomeia de emancipatória. Da distinção metodológica de ambas, espera-se discernir a filosofia da história e da natureza que estaria contida em sua obra.

Procurou-se relacionar as informações disponíveis sobre os organoclorados e os efeitos crônicos provocados pela exposição. Os compostos organoclorados são os praguicidas mais persistentes já fabricados. Embora sejam geralmente eficientes no controle das pragas, são importantes poluentes ambientais e potenciais causas de problemas de saúde para o homem, tendo sido proibidos ou controlados na maioria dos países. Com poucas exceções, os efeitos tardios desses compostos sobre a saúde humana são difíceis de detectar, em função de dificuldades metodológicas e da extrapolação dos resultados. A genotoxicidade está entre os mais sérios dos possíveis danos causados por esses compostos e merece atenção especial, devido à natureza irreversível do processo. Outro ponto a ser considerado é o aumento na incidência de alterações no desenvolvimento do trato reprodutivo e na fertilidade masculina observada nas últimas décadas provavelmente decorrente do aumento da exposição intra-uterina a compostos estrogênicos e anti-androgênicos, como os organoclorados.

O presente artigo tem por finalidade apresentar uma abordagem histórica do setor energético no estado do Amapá, com o intuito de compreender ação energética até interligação ao Sistema Interligado Nacional – SIN. Diante dessa conjectura, surgiu o seguinte questionamento: Como se deu a demanda de consumo de energia elétrica nesse período? A hipótese apresentada indica o inchaço populacional como aumento da demanda, que causou estrangulamento de energia por falta de investimentos no setor. Para responder tal pergunta, foram feitas pesquisas bibliográficas e de campo e posteriormente análise, para estruturação dos dados. O resultado aponta para uma iniciativa do Governo Federal em incentivar o interesse em explorar esse lote, o qual foi ofertado através de leilão em 2008. A empresa ganhadora foi a ISOLUX. Com a interligação completa, o estado passa a integrar o Sistema Interligado Nacional, completando a rede elétrica brasileira, que é composta hoje por diversas usinas produtoras e distribuidoras ao mesmo tempo. Diante desse cenário, o estado hoje comporta energia firme para atendimento local, bem como exportação, saindo de uma situação de estrangulamento de produção para expansão da energia.

Resumo Hoje em dia é crescente a quantidade de estudos envolvendo a utilização de cargas ou aditivos nos materiais poliméricos, em especial no poliestireno, a fim de atuar como retardante de chama. Partindo desse princípio, este trabalho compara o comportamento térmico dos compósitos de poliestireno/hidróxido duplo lamelar magnésio-alumínio (PS-HDL [Mg-Al]) em relação ao poliestireno puro. Os compostos foram preparados com HDL, quimicamente modificado com dodecil sulfato de sódio (SDS-Na) ou com dodecilbenzeno sulfonato de sódio (DBS-Na). A síntese desses aditivos (HDL-SDS e HDL-DBS) foi feita pelo método de coprecipitação e inseridos no PS via solubilização em clorofórmio. Os compostos foram caracterizados por difratometria de raios-X e espectroscopia de infravermelho por transformada de Fourier, onde o primeiro comprovou a intercalação do DBS/SDS com o HDL e o segundo confirmou a presença dos grupos característicos no HDL. Através da análise termogravimétrica, avaliaram-se as propriedades térmicas do compósito. Os resultados mostraram que o PS-HDL modificado comporta-se melhor que o PS puro, pois apresenta maior estabilidade térmica. Comparando-os em uma perda de massa de 50%, o PS-HDL-SDS apresentou resultado superior ao PS puro, com um ganho de aproximadamente 44 ºC na temperatura de decomposição térmica.

Composting has become a preferable option to treat organic wastes to obtain a final stable sanitized product that can be used as an organic amendment. From home composting to big municipal waste treatment plants, composting is one of the few technologies that can be practically implemented at any scale. This review explores some of the essential issues in the field of composting/compost research: on one hand, the main parameters related to composting performance are compiled, with especial emphasis on the maturity and stability of compost; on the other hand, the main rules of applying compost on crops and other applications are explored in detail, including all the effects that compost can have on agricultural land. Especial attention is paid to aspects such as the improvement of the fertility of soils once compost is applied, the suppressor effect of compost and some negative experiences of massive compost application.

Food waste is a vast issue global, including in Malaysia. Food waste brings negative impacts, including increasing food production costs, impact on human health, and environmental degradation. Malaysian’s animal- and plant-based diet preferences affected the desired food waste decomposition method as most of the methods only allow plant-based material to be utilized as food waste compost. The objectives of this study were to understand Malaysians' awareness of food waste behaviour and the food waste component for the decomposition. Malaysians usually produce more plant-based food waste than animal-based food waste. Most Malaysians have a high awareness of causes and impact of food waste, but they lack action on food waste reduction. Bio-compost is believed to be the most effective method to manage food waste, and most of them were willing to have it at home. However, some of them are unwilling to have a compost pile at home because there is no time to take care of it.

Dentes com grande destruição coronária submetidos a tratamento endodôntico devem ser reconstruídos por meio da inserção de um pino intrarradicular, com finalidade de se obter retenção para o material restaurador e melhor distribuição de forças sobre o remanescente dental. A reconstrução coronária desses elementos dentais pode ser realizada com técnicas restauradoras indiretas ou diretas. A evolução das técnicas operatórias e das propriedades físicas, mecânicas e estéticas das resinas compostas tem ampliado suas indicações clínicas, e, quando associadas a pinos intracanais cimentáveis, têm permitido avanços nas reconstruções dentárias. Muitas situações clínicas, que tradicionalmente apresentavam soluções protéticas, hoje podem ser resolvidas através de restaurações diretas com resina composta. Este trabalho apresenta dois casos clínicos onde se realizaram alternativas viáveis de reabilitação de dentes com grande destruição coronária utilizando reconstruções totais diretas com uma resina composta micro-híbrida como material de eleição, associada à utilização de um pino de fibra de vidro e um pino metálico pré-fabricado. Em ambos os casos, foram realizadas as cimentações dos pinos intracanais com cimento ionomérico modificado por resina, seguindo o protocolo tradicional para desobturação dos canais radiculares. Associada ao pino de fibra de vidro foi utilizada a técnica da matriz de silicona como meio para reconstruir a coroa dental, enquanto que junto ao pino metálico lançou-se mão da matriz de Ableh. Concluiu-se que as técnicas descritas constituem procedimentos alternativos, de baixo custo e rápida elaboração, conseguindo suprir as necessidades dos pacientes, demostrando ser uma boa opção para reabilitação de grandes destruições coronárias.

This article brings together the crime fiction novels of Richard Stark (a pseudonym of Donald Westlake) and the philosophical ideas of Peter Sloterdijk. Influential and yet critically neglected, Stark's ‘Parker novels’ feature an amoral and unchanging thief named Parker who infiltrates and exploits an array of settings for his criminal activities. Two of the main recurring situations in these novels involve Parker either breaking into and searching the home of a rival or using an empty home as a temporary hideaway. This article argues that Parker's approach to homes invokes elements in Sloterdijk's theorization of dwellings, including his broad theory that contemporary Western society is arranged in a manner reminiscent of bubbles in a ‘mountain of foam’, as well as his specific ideas about how contemporary dwellings function as spheres that aim for both individualistic privacy and access to mobile networks. The article draws upon these theories to explore how Stark's novel Flashfire represents Parker's attempts to establish a private sphere for his own use in Palm Beach, Florida, a process which ultimately exposes the limits of the ‘foam’ that composes his world of heists and brutal practicality.

This research aimed to evaluate the effect of doses of organic compost on the yield and economic profitability of organic yellow passion fruit grown in sandy-loam and clay-loam soils. Two experiments were installed in the field, in different soil types and municipalities in the state of Acre. The experimental design was in randomized blocks with five treatments, four replications, and four plants per experimental unit. The treatments consisted of adding the compost as a replacement for 1/3 of the volume of cylindrical planting holes with 40 cm, 80 cm, 120 cm, 160 cm, and 200 cm, corresponding to the addition of 6.3; 25.1; 56.5; 100.4, and 156.9 liters per planting hole, respectively. The mean fruit mass and the yield of the yellow passion fruit were higher in sandy-loam soil. The total revenue was R$ 4,311.6 ha-1 in the clayey soil and R$ 5,841.9 ha-1 in the sandy soil. The total cost was higher in the clayey soil than in sandy soil. Both soils responded in quadratic function with an increase in the cost as the volume of organic compost was increased, ranging from R$ 12,736.00 ha-1 with 6.3 liters of compost per hole up to R$ 26,249.63 ha-1 with 156.9 liters of compost per hole. Net income was negative for all compost volumes in both types of soil, responding linearly, with a reduction in revenue of R$ 80.82 ha-1 with the addition of each liter of compost in the pit due to the low yield caused by period long drought.

<abstract> <p>In this study, a survey was conducted to determine the public opinion regarding the acceptance of using home composters as an alternative approach for household organic waste management. This approach is introduced as a method to replace the landfilling of organic municipal solid waste, which is the main solid waste management currently employed in Palestine, considering Anabta town as a case study. The results showed that people in the target area are welcoming of the home composting idea, and about 99% of participants are interested in owning home composters at their properties, which is regarded as a good reference for implementing the proposed home composting scheme in this area. The results showed that people are interested in the new proposed scheme for organic household waste despite their minimal knowledge and understanding about the composting process's importance and effects. The survey tested the people's expectations and thoughts about the home composting concept and found that the main motives for home composting were reducing the cost of house gardening and using the produced compost in soil nutrition, besides being part of environmental sustainability. On the other side, obstacles were due to people's inexperience of the home composting method, as almost half of participants were expecting an exhausting, long process to produce compost, with the related bad smell and insects during composting progression. Hence, the study found that it is important to spread awareness about the right procedures to apply home composting among participants, in line with environmental awareness campaigns through social media, and provide personalized follow-up with participants.</p> </abstract>

Tegalweru village, Dau, Malang regency is known as a high producer of horticultural crops with a total area of horticultural crops to ± 336 ha or 80% of the total area of agricultural land. To maintain the productivity of horticultural crops is necessary land management system with organic inputs. However, the availability of compost in this village is still inadequate. Compost production system that is not running optimally, although it has been available the tools for composting. An understanding of composting technology is still low. Specific targets to be achieved in this activity is an increase in the compost product produced from compost production systems that exist in the two farmers groups Weru Asih I and II, who became a partner in this activity. IbM activities were implemented through several stages: (1) extension of composting technology and the role of organic matter (2) the training and mentoring of making compost, (3) Building composting home, and (4) Counseling and guidance of management system of sustainable compost production. The results of this work showed that horticultural farmers at Tegalweru village already can independently make compost with a high quality. This activity greatly helped to provide compost for farmers. It is also able to improve the understanding of the members of farmer group in maintaining soil fertility. For the sustainability of this program, implementation of barter management system between compost material with mature compost can be used as an initial step in the development of commercial compost production at Tegaweru village.

A bacterial strain, DC-186T, isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15–36 °C and pH 5.5–8.0. Strain DC-186T was positive in tests for catalase, oxidase and β-galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C16 : 1/iso-C15 : 0 2-OH (42 %) and iso-C15 : 0 (26 %), the major respiratory quinone was menaquinone-7 and the genomic DNA G+C content was 42 mol%. 16S rRNA gene sequence analysis and phenetic characterization indicated that this organism belongs to the phylum Bacteroidetes and revealed its affiliation to the family Sphingobacteriaceae. Of recognized taxa, strain DC-186T was most closely related to Sphingobacterium daejeonense (90 % sequence similarity) based on 16S rRNA gene sequence analysis. The low 16S rRNA gene sequence similarity with other recognized taxa and the identification of distinctive phenetic features for this isolate support the definition of a new genus within the family Sphingobacteriaceae. The name Pseudosphingobacterium domesticum gen. nov., sp. nov. is proposed, with strain DC-186T (=CCUG 54353T=LMG 23837T) as the type strain.

This essay is a summary of a training activity of water conservation and application of biopori holes at two villages in Bengkulu Province, i.e. Pering Baru village surrounded by palm cultivation, Suro Lembak dominated by vegetable farming. Both villages were experienced with shortage of water during dry season and plenty of water during rainy season. So people from both villages were eager to be trained on water conservation and implementation of biopori hole. Water conservation in palm plantation and vegetable farming were done by making ditches perpendicular with the slope of lands in order to collect runoff water and lead to infiltration. Moreover, biopori holes could be constructed around their homes in order to increase water infiltration, and also to be used as organic waste digester for producing composts. This biopori holes protected from malaria diseases due to no more stagnant water.

O mercúrio é um composto metálico em forma líquida na temperatura ambiente, com uma expansão volumétrica presente em ampla faixa de temperatura, com alta tensão superficial e não adere a superfícies vítreas. Estas características levam a aplicação deste material em aparelhos de medição de pressão e temperatura, Também tem uma facilidade de formação de amálgamas com aplicação na metalurgia, odontologia, processos extrativos outros metais. Porém este produto tem uma grande toxicidade que pode prejudicar a saúde do homem e o meio ambiente. Existem vários meios de contaminação do meio ambiente pelo mercúrio. Um dos principais meios é a contaminação com os resíduos de amálgamas, advindos de consultórios odontológicos, descartados como lixo comum ou pelos ralos do sugador do consultório. O tratamento clássico para pequenas quantidades de mercúrio elementar envolve a aspiração com capilar conectado a uma bomba para coleta das gotas, a adição de polissulfato de cálcio ou enxofre em excesso para passivação do mercúrio e, em seguida, recuperação ou disposição final. A disposição pode ser feita em aterro apropriado ou, preferencialmente, através do encapsulamento (cimentação ou vitrificação). A maioria dos processos de tratamento de resíduos de compostos contendo mercúrio baseia-se na simples transferência de fase deste metal, para que se possa proceder a disposição final, o que ratifica a importância de alternativas que visem o reuso e reciclo. Este artigo tem o objetivo de apresentar métodos de tratamento dos resíduos que contenham mercúrio para a diminuição de sua toxicidade ao homem e ao meio ambiente.

RESUMO As plantas medicinais representam um dos principais recursos terapêuticos utilizado pelo homem para a cura e prevenção de doenças, no entanto, para que o tratamento seja seguro e eficaz é necessário conhecer seus componentes químicos. Dessa forma, o intuito deste trabalho foi determinar os parâmetros farmacognosticos para o estabelecimento do controle de qualidade da droga vegetal composta pelas folhas de Erythroxylum suberosum A. St.-Hil., pertencentes à família Erythroxylaceae ocorrente no Cerrado. Para tanto, foram coletadas folhas adultas nas proximidades da Universidade Federal de Goiás, Goiânia-GO. Foram determinados o teor de umidade por meio de balança com irradiação de raios infravermelho e o teor de cinzas totais. Na prospecção fitoquímica foram pesquisadas as classes de metabólitos secundários e realizou-se o doseamento de fenóis totais, flavonoides e taninos totais. Os resultados dos testes de pureza realizados, teor de umidade e teor de cinzas totais, estão de acordo com os limites estabelecidos pelas especificações farmacopeicas. As análises fitoquímicas evidenciaram a presença de flavonoides, taninos, cumarinas, saponinas e resinas. No doseamento de fenóis totais, taninos e flavonoides presentes nas folhas de E. suberosum A. St.-Hil. obteve-se respectivamente 17,97%, 6,31%, 3,87%. Estes resultados confirmam os dados da literatura quanto à presença destes compostos em Erythroxylaceae, pois de acordo com nas folhas de E. tortuosum obteve-se valores de 10%, 8,4% e 0,064% de Fenóis, Taninos e flavonoides, respectivamente e nas folhas de E. deciduum foram encontrados 12,04% de fenóis totais, 0,87% de taninos e 1,37% de flavonoides. Os resultados encontrados no presente trabalho também se tornam relevantes quando comparadas as quantidades desses metabólitos com espécies clássicas na biossíntese de compostos fenólicos como o teor de taninos de Stryphnodendron adstringens (Mart.) Coville e em Eugenia uniflora L. foi de 29,9% e 2,96%, respectivamente. Teores de flavonóides que variaram entre 0,65% a 0,79% na Calendula officinalis L. e Ginkgo bilobaL. 0,59%, 0,75% e 0,79%. Sendo assim, a quantidade considerável de compostos fenólicos obtida em E. suberosum A. St.-Hil. sugere que a espécie possua um importante potencial terapêutico e quem sabe potencial antioxidante, a ser explorado em estudos posteriores.

Lentinula edodes (cogumelo "shiitake") é um fungo basidiomiceto que apresenta propriedades nutricionais, medicinais e antibióticas. Compostos de interesse para o homem têm sido isolados do basidiocarpo e dos filtrados de cultura obtidos a partir do crescimento micelial. O presente trabalho teve como objetivos avaliar o efeito de diferentes preparações de L. edodes sobre patógenos da cultura do sorgo, Exserohilum turcicum e Colletotrichum sublineolum, bem como a proteção das plantas de sorgo contra estes patógenos. Em testes com placas de Petri e lâminas de vidro para microscopia, extratos aquosos obtidos do basidiocarpo inteiro e de suas partes individualizadas, píleo e estipe, reduziram a taxa de crescimento micelial e inibiram a germinação de esporos dos fungos, enquanto a atividade antifúngica do filtrado de crescimento micelial foi menos pronunciada. Em mesocótilos de sorgo, as diferentes preparações do "shiitake" não provocaram o acúmulo de fitoalexinas. O extrato aquoso do basidiocarpo e o composto lentinana reduziram parcialmente a severidade das doenças provocadas por E. turcicum na cv. Brandes e por C. sublineolum na cv. Tx-398-B, quando pulverizados 48 horas antes da inoculação das plantas, sob condições de casa de vegetação. Portanto, L. edodes apresenta potencial como agente de controle biológico ou como um modelo para a síntese de substâncias fungicidas.

As salinas têm sido utilizadas pelo homem há milênios, sendo compostas por uma série de tanques rasos e interconectados, nos quais a água do mar/estuário é captada e transferida de um tanque para outro por gravidade ou por bombeamento, onde a produção do sal se dá a partir da saturação e precipitação dos sais por evaporação solar. Objetivou-se identificar e descrever o processo de deposição e formação de sais em ambientes evaporíticos artificiais (salinas solares) do Brasil. Verificou-se que a precipitação de sais nas salinas incluiu os compostos menos solúveis na base para o mais solúvel na parte superior da sequência, na seguinte ordem: carbonatos (CaCO3), gipsita (CaSO42H2O), halita (NaCl), sais de potássio - silvinita (sistema NaCl-KCl), e magnésio - biscofita (MgCl2.6H2O). Os carbonatos precipitam-se em salinidades em torno de 50 a 80gL-1, seguidos dos sulfatos, que precipitam-se gradativamente ao longo dos evaporadores da salina, até atingir seu máximo de precipitação entre 150 e 160gL-1. As maiores quantidades de cristais de halita são formadas quando a concentração total da salinidade atingiu um valor acima de 240gL-1. A variação e sequência de deposição evaporítica nas salinas apresentam limites diferentes de dissolução no ambiente, vindo a precipitar-se quando atingem saturações máximas.

INCREASING OF HOUSEWIVES POTENTIAL IN PROCESSING DOMESTIC ORGANIC WASTE BY USING TAKAKURA METHOD IN CIBIRU WETAN VILLAGE, BANDUNG REGENCY. Domestic waste (DW) is a major environmental challenge for many urban local bodies in Indonesia both in the village and in the city, where urbanization, industrialization and economic growth have resulted in increased waste generation per person. One way to solve this waste is to turn organic domestic into compost. Composting, the recycling of organic waste such as vegetation and food waste reduces the amount of waste going to landfill and is, therefore, a rapidly growing sector. Desa Cibiru Wetan, Kab. Bandung, West Java is one of the villages that has learned about how to process organic waste into compost and become a pilot project but because of the distance between raw materials and management with compost incubator so that compost production is disturbed. Therefore, the purpose of the project activity was to produce compost from domestic organic waste by the Takakura method. In this method, a small incubator was used and placed at the home of the community. Although on a small scale but with many multipliers, it able to produce an abundant compost and can be an alternative for the existing compost incubator method. The stage included counseling and socialization, training in making incubator Takakura, training in production compos,t and monitoring and evaluation. The results showed a good understanding of both groups for both the socialization and counseling stages as well as for the practice of production of compost. In conclusion, the activity on the production of compost by using Takakura method able was to solved for domestic organic waste and remind set the interest of the community in producing compost.
