 A conservação de fragmentos florestais é extremamente necessária para garantir a manutenção da biodiversidade, além de assegurar o armazenamento de carbono contido na biomassa e nos solos. O município de Curitiba (PR, Brasil) possui 52 áreas protegidas municipais com remanescentes de Floresta Ombrófila Mista (FOM) em diferentes estágios de conservação, as quais contribuem para a manutenção da biodiversidade, melhoria da qualidade de vida dos moradores e também auxiliam na mitigação das mudanças climáticas, pois estocam grandes quantidades de carbono nos diversos componentes florestais. O presente estudo foi desenvolvido com o objetivo de avaliar a importância dos fragmentos florestais de Curitiba na manutenção dos estoques de carbono de forma associada à sua importância para a preservação da biodiversidade, o que pode servir de incentivo para o investimento público nessas áreas e de estímulo a outros municípios para a criação e manutenção de UCs. O estoque de carbono contido nos remanescentes florestais do município (1.159.259,60 t C) reforça a importância da conservação de remanescentes de vegetação nativa, ainda que em meio ao ambiente urbano.Palavras-chave: Carbono; desmatamento evitado; Floresta com Araucária; áreas verdes urbanas. AbstractProtected Areas in Curitiba, PR, Brazil, as carbon sinks.Conservation of forest’s fragments is extremely necessary to ensure maintenance of biodiversity and storage of carbon. There are currently 52 protected areas (PAs) in Curitiba municipality, located in Parana State – Brazil, with remnants of Araucaria Forest at different stages of conservation contributing to maintenance of biodiversity, improving quality of life of residents and also assisting in prevention of climate change as the aforementioned areas store large amounts of carbon in a range of forest components. In 2009, Curitiba conducted a research to estimate the carbon stock of forest fragments. The present research was carried out in order to evaluate the importance of these fragments in the maintenance of carbon stocks, associated to the preservation of biodiversity, which may be an incentive for public investment in these areas and encouragement to other municipalities for the creation and maintenance of PAs. Based on available information on the carbon contained in forest remnants of the city, it was identified that the total of those areas involves a stock of 1,159,259.60 t C, which reinforces the importance of maintaining native vegetation even in urban environment. Keywords: Carbon; deforestation prevention; Araucaria Forest; urban protected areas.

This article looked at the quantity and storage time of attiéké produced and sold in the town of Daloa. It also examines the microbiological characteristics of attiéké-femme and attiéké-garba from this locality during storage. The study was carried out on the one hand through a field survey carried out on the producers and sellers. On the other hand, a sample was taken from 10 sellers of attiéké-garba and 10 sellers of attiéké-woman. The study found that the women producers sell 87% of their production in the city of Daloa and export 13%. In addition, attiéké can be kept for 2 days at the producers and beyond 2 days at the sellers before their stock runs out. Therefore, a weekly production of more than 200 kg for the majority of the producers is observed. Microbiological analyses showed high levels of germs (MAG: 6.106 CFU/g; Yeasts and moulds: 2.7.106 CFU/g) for attiéké-women and (2.106 CFU/g of GAM and 1.6.103 CFU/g of Yeasts and moulds) for attiéké-garba. Total coliforms and faecal coliforms were only found in attiéké-women. No salmonella was observed. In view of the results, it should be noted that female attiéké is the most contaminated type of attiéké.

The Atlantic Forest is highly anthropized, this reduce the areas of native vegetation and impacts the biodiversity of the biome. The objective of this study is to analyze forest remnants with native vegetation characteristics using a free GIS. This analysis takes place using landscape metrics and was based on the supervised vectorization of land use in the municipality of California, PR. The area of the vectored polygons was obtained and a classified, and then the calculation was made with the nearest neighbor index, mean distance observed, Patton diversity index and the perimeter/area ratio of forest fragments. The results show that most of the fragments have an area smaller than 1 ha, the fragments with more significant area (<50 ha) represent more than 16% of the native vegetation area. The small fragments are important to maintain the connectivity, since the withdrawal of these increases the mean distance observed and nearest neighbor index. Most of the fragments are elongated and amorphous in accordance with the perimeter/area ratio and the Patton diversity index respectively, this may demonstrate the fragments may be subject to edge effects. Even with these characteristics, these fragments may be part of what is planned in public policy for preservation in the Atlantic Forest in the state of Paraná. Therefore, even small fragments with little core area are important for maintaining biodiversity, especially in a highly anthropogenic landscape

Theobroma Cacao L

Aim: To assess the impacts of rodent pests on Cocoa (Theobroma cacao) production and productivity. Rodents belong to the mammalian order that is widely distributed globally. Their adaptive potential and capability to face changing environments even when instigated by anthropogenic activities is quite amazing. Also, their importance as vital links in food chain between species of plants and the predators thereby playing crucial roles within the ecosystem cannot be overemphasized. Rodents have been noted to cause ubiquitous damage to agricultural crops including cocoa. They can cause damage in crop fields from planting throughout harvest and storage. The damages caused by rodent pests mostly occur during the sensitive young seedling stage and just prior to harvesting. The pattern and the extent of damage by pest rodents depend upon the species, the intensity of infestation, the type and the growth stage of the crop, and the nature of the surrounding habitat. These damages caused by rodent pests could be direct through the consumption of cocoa beans or indirect through the biting, gnawing or scratching of pods which could range from slight to severe. The stern impacts caused as a result of rodent pest activities are not only felt in the quantity and quality of cocoa pods but also on the social maintenance as well as survival of those growing the crop. Despite the paucity of documented data as regards the kind, form as well as ferocity of rodent damage, it is highly expedient to re-evaluate the rodent pests’ impacts on the production of cocoa so as to update the very scarce available information whilst providing a basis for additional investigation.

Biological Studies

Flies from the Drosophilidae family are model organisms for biological studies and are often suggested as bioindicators of environmental quality. The Araucaria Forest, one of Atlantic Forest phyto-physiognomy, displays a highly fragmented distribution due to the expansion of agriculture and urbanization. Thus, this work aimed to evaluate and compare the drosophilid assemblages from two highland Araucaria Forest fragments, one a conservation unit (PMA – Parque Municipal das Araucárias) and the other a private property without any conservational policy (FBL – Fazenda Brandalise), in space and time, using species abundances and richness, ecological indexes and Neotropical and exotic species proportions as parameters to establish the level of environmental quality of these fragments. Our results showed that the observed diversity in PMA (H′ = 2.221) was approximately 40% higher than in FBL (H′ = 1.592). This could be due to higher preservation quality and habitat diversity in PMA, indicating the importance of conservation units. However, richness were similar for these areas, with PMA (Dmg = 6.602) only 8% higher than FBL (Dmg = 6.128), which suggest that the larger distance from city limits and the larger size of FBL forested area could be compensating the higher disturbance caused by antrophic extractive exploitation of this fragment. This points out that, besides the quality of presevertion, the size and/or connection with other fragments should be considered for areas destined for biodiversity conservation. In general, both areas presented similar drosophilid assemblages, and the expressive abundance of both Neotropical species (mostly of the subgroup willistoni) and the exotic species D. kikkawai suggests that these areas are in intermediate stages of conservation.

The manufacturing process, the source (raw materials), and primary packaging materials dictate requirements for the quality of ethyl alcohol used in the pharmaceutical industry.The aim of the paper was to analyse how the quality of ethyl alcohol used as a component of medicinal products depends on the starting materials, production method and technology, intended use, and the choice of the primary packaging. The paper analyses available information on ethyl alcohol quality and summarises data on potential impurities associated with the ethyl alcohol production technology and the starting materials used. It was established that Russian manufacturers mainly use grain crops (wheat and rye), as well as molasses—a by-product of the sugar industry, as raw materials. The paper addresses the process of improving the quality standards for ethyl alcohol from a historical perspective. A comparative study of the requirements of the Russian and the world’s leading pharmacopoeias for the pharmaceutical substance—ethyl alcohol 95%, 96% demonstrated the need to include identification by IR-spectrometry and impurity control by UV absorbance into the respective monograph of the State Pharmacopoeia of the Russian Federation. The authors formulated requirements for the choice of packaging material for ethyl alcohol, which will not affect its quality during transportation and storage.

Public bicycle and car sharing schemes have proliferated in recent years and are increasingly part of the urban transport landscape. Shared transport options have the potential to support social inclusion by improving accessibility: these initiatives could remove some of the barriers to car ownership or bicycle usage such as upfront costs, maintenance and storage. However, the existing evidence base indicates that, in reality, users are most likely to be white, male and middle class. This paper argues that there is a need to consider the social inclusivity of sharing schemes and to develop appropriate evaluation frameworks accordingly. We therefore open by considering ways in which shared transport schemes might be inclusive or not, using a framework developed from accessibility planning. In the second part of the paper, we use the case study of Glasgow in Scotland to undertake a spatial equity analysis of such schemes. We examine how well they serve different population groups across the city, using the locations of bicycle stations and car club parking spaces in Glasgow, comparing and contrasting bike and car. An apparent failure to deliver benefits across the demographic spectrum raises important questions about the socially inclusive nature of public investment in similar schemes.

The waste cooking oils (WCOs), when wrongly discarded, bring environmental damages, additionally to structural problems and financial losses if released in the sewage system. However, the correct management of this residue allows its reuse and recycling, representing economic gains, besides social and environmental benefits. There are several alternatives to recycling and reusing WCOs and the biodiesel production presents itself as one of the most important. Nevertheless, it is necessary to guarantee the residue quality in order to utilize its potential, as well as a coordinated management of WCO, promoting the correct processing and disposal of this waste. In this context, this article aims to propose an environmentally appropriate WCO onsite handling and collection in Lavras-MG, by evaluating the WCO management at three establishments in the city. The evaluation had taken into account the quantity of WCO generated, handling, storage and collection methods adopted, and the quality of the residue, by analyzing levels of acid, iodine and peroxide and saponification value. The results revealed the current management of the WCO, the actors involved in the management chain, the way the different frying and storage processes influence the WCO quality for reusing and recycling and possible alternatives to improve the management. The WCO management chain, composed of ACAMAR, G-Óleo, E1 and E2, is widespread and shows potential to transform the WCO into several other products, in addition to biodiesel and handmade soap. At long last to coordinate the correct WCO handling, collection, processing and disposal it is essential to guarantee the participation of the generators, collectors, and the government.

Abstract The Hârtibaciu River is channelled (covered by concrete) near the city of Agnita and represents the confluence of numerous sources of local pollution having a negative impact both qualitatively and quantitatively. Lack of riparian vegetation gives the Hârtibaciu River an unpleasant aspect and cannot provide an efficient filter. This ecotechnical method helps to protect the special protected areas (SPAs) into Hârtibaciu River basin and to clean the river in the city of Agnita. By the means of this method the quality of the Cibin River can also be improved, as the Hârtibaciu River is a tributary of it

The proliferation of substandard drugs is a major public health challenge, especially in developing countries which lacks adequate resources to effectively monitor their prevalence. Currently, there are no reliable statistics on the level of incidence of fake drugs in Nigeria. The quality of medicines is an integral part in ensuring that pharmaceutical products are fit for their intended use, comply with requirements of marketing authorization and do not expose consumers to risks. For this to be achieved, there must be a system of quality assurance, which incorporates aspects including product development, manufacturing, distribution, and storage. This study aimed at quantifying the content of ten (10) brands of metronidazole infusion marketed in Abuja by UV-Spectroscopic method. Ten (10) brands of metronidazole were purchased in different pharmacies within the city of Abuja and were assayed using UV-Spectroscopic method as stated in British Pharmacopoeia 2017 edition. All the ten (10) brands of metronidazole that were assayed had a percentage content of 100.97% to 108.15%. From the study carried out, all the brands of metronidazole infusion complied with the content uniformity test as stated in the British Pharmacopeia.

Abstract The factors that can influence the environmental valuation of urban forest fragments (UFFs) in two neighborhoods of the city of Manaus (AM) were assessed. The valuation data were obtained through the technique of pile sorting followed by ranking, considering 14 socioenvironmental attributes. Most of the residents (59%, N = 69) mentioned positive feelings (topophilia) regarding the conservation of the fragments in the urban landscape. The attributes associated with the ecocentric vision were those that received the highest positive values, followed by anthropocentric attributes associated with the direct non-consumptive use of environmental resources, such as “aesthetic” and “learning”. Residents who live closer tended to value the fragment more than distant residents, and the opposite occurred when there was an association between the presence of the fragment and violence and crime in the neighborhood. Among the socioeconomic variables investigated, only the time as a resident seemed to be related to the way the city residents value these forest remnants.
