The geographically uniform Texas Panhandle is dotted with shallow, ephemeral water bodies (playas), that quickly expand and contract in size. Numerous playas have been incorporated into the storm and surface-water management plan for the City of Lubbock, Texas; these playas often are surrounded by public parks. In the past, trees were planted around playas without regard to their flood tolerance. For these reasons, the objectives of this study were to catalogue trees around city playas and to determine which of these tree species survived inundation. The trees in the flood zones of eight city parks were catalogued by species in 1995, immediately after a 5-inch rain event. The water levels in all parks were monitored for the subsequent 4-month period to determine inundation time for each tree. The health of these trees was visually assessed annually. Bald cypress, mulberry, American elm, and sycamore improved in health, while the other tree species declined. Surprisingly, weeping willow and corkscrew willow, along with cedar elm, suffered the greatest decline in health.

This research aimed to identify water resources management strategies in extreme drought event scenarios in the municipality of Lucrécia, in the state of Rio Grande do Norte (RN), in the period 2012 to 2018. As a methodological procedure, a bibliographical and documentary, in addition to field research, with interviews with municipal managers and residents. A photographic record of the study area was also carried out. It was found that, in the city, there is a folder dedicated to water resources that guides water management and is the basis for the adoption of measures aimed at municipal supply in times of difficult access to water, due to the reduction in water availability. It was observed that part of the interviewed population understands the drought as responsible for the difficulties faced in the city, mainly about the reduction of the water level in the reservoir. It was found that, of the 52 towns belonging to the hydrographic basin of the Apodi-Mossoró river, only 10 participate in the meetings of the basin committee, the municipality of Lucrécia does not have representatives on the Committee. This finding deserves special consideration since water and the administration of its multiple applications are generators of conflicts, it highlights the importance of understanding how municipalities in the Semiarid region carry out the management of water resources and how they understand the challenges of coexistence with its area, aiming at the sustainable use of water.

The objective of the research was to diagnose the presence of parasites in coriander (Coriandrum sativum L.) sold in supermarkets and open markets in the city of Mossoró, State of Rio Grande do Norte. In total, 40 samples of coriander were analyzed, 20 of which were sold at open markets and 20 from supermarkets, in search of parasitic structures using the spontaneous sedimentation technique, followed by microscopic analysis. Four supermarkets and four stalls at an open market were randomly analyzed. Among the 40 samples analyzed, 27.5% (11/40) were positive for parasitological contamination, of which 81.8% (9/11) came from open markets and 18.2% (2/11) supermarkets. Among the positive samples, parasitic structures of the genera Ancylostoma sp., Toxocara sp., and Strongyloides sp. Thus, it is concluded that the results demonstrate that a considerable index of the samples is unsuitable for human consumption, and may cause harm to the health of the consumer.

Objetivou-se estudar a qualidade da carcaça bovina comercializada no município de Assunção na região do Cariri paraibano, onde se verificou os fatores que influenciam a qualidade da carne, desde as condições antes, durante e depois do abate, bem como a comercialização, e a higiene-sanitária, através dos procedimentos metodológicos: entrevistas com os comerciantes, visitas aos abatedouros e pontos comerciais, além de análise microbiológica das carnes, fazendo a comparação da carne comercializada na feira livre e no açougue. Os resultados obtidos apontaram que vários motivos levam os consumidores a adquirir a carne nesses pontos comerciais, como forma de pagamento, preço, conhecimento da origem e abate do animal, qualidade, falta de opção, entre outros, havendo destaque para o preço na feira livre (29%) e a forma de pagamento no açougue (27%). Na entrevista com os consumidores, a carne foi classificada como boa, regular e ruim; sendo que 60% dos consumidores (açougue) e 42% (feira livre) consideraram a qualidade da carne como boa; 40% (açougue) e 42% (feira livre), a consideraram regular, e 17% (feira livre) classificou a mesma como ruim. A análise microbiológica efetuada comprovou que todas as amostras coletadas encontraram altos índices de contaminação, estando muito acima do limite permitido pela legislação vigente no país para os parâmetros pesquisados, especialmente na feira livre, onde foram evidenciados os maiores índices de contaminação, principalmente pela presença de Salmonella spp. Comprovando que se faz necessário um maior controle de qualidade da carne comercializada em ambos os estabelecimentos.Quality of bovine carcass marketed in the municipality of Assunção, ParaíbaAbstract: This work aimed to study the bovine carcass quality marketed in the city of Assunção in the region of Cariri Paraíba, where it was found the factors that influence the quality of meat from the conditions before, during and after slaughter and marketing, and hygiene, through methodological procedure: interviews with traders, visits to abattoirs and trade points, and microbiological analysis of meat, making the comparison of the meat sold in the open market and butcher. The results showed that various reasons lead consumers to purchase the meat in these outlets as a means of payment, price, knowledge of the origin and slaughter of the animal, quality, lack of choice, among others, with emphasis on the price on the open market (29%) and the form of payment in the meat (27%). In the interview with the consumer, the meat was classified as good, fair and poor; and 60% of consumers (butchers) and 42% (open market) considered the quality of the meat as good; 40% (butcher) and 42% (flea market), the considered regular, and 17% (open market) ranked the same as bad. Microbiological analysis performed, proved that all the collected samples found high levels of contamination, is well above the limit allowed by law in the country for the studied parameters, especially in the free market, where the highest infection rates were evidenced mainly by the presence Salmonella spp. Proving that it is necessary a greater quality control of meat sold in both establishments.

Este trabalho tem como objetivo aplicar os índices de vegetação SAVI e NDVI no Sítio PELD 22, área experimental de Petrolina, numa série de imagens do satélite Landsat 5, sensor TM, do período 2001 – 2010. A intenção é observar o comportamento da vegetação durante os distintos períodos, bem como as diferentes informações que os dois índices podem apresentar das mesmas superfícies. A área em questão compreende uma reserva ecológica pertencente à EMBRAPA/Semiárido, lotada no município de Petrolina – PE, que foi cedida por esta instituição à rede de Pesquisa de Longa Duração – PELD, sitio 22. Para isto foram utilizadas seis imagens da série acima descrita, a partir das quais foram gerados mapas e histogramas para auxiliar na interpretação das informações apresentadas. Para o perído seco em área de Caatinga sugere-se que se use o SAVI para determinação dos indices de vegetação quando comparado com NDVI, pois o efeito background, reflectância do solo, interfere nas respostas da cobertura vegetal e assim o NDVI apresenta uma subestimativa da cobertura vegetal. Palavras - chave: Caatinga, Índices de Vegetação, IVDN, IVAS.  Comparative Analysis of Changes in NDVI and SAVI in PELD - 22 - Petrolina - PE, in the First Decade of the XXI Century  ABSTRACT This work aims to apply the vegetation index NDVI and SAVI in PELD site of Petrolina, a series of satellite images from Landsat 5 TM sensor, the period from 2001 to 2010. The intention is to observe the behavior of vegetation during the different periods, as well as the different information that the two indices may show the same surfaces. The area in question includes an ecological reserve belonging to the EMBRAPA/Semiarid, located in the city of Petrolina - PE, which was ceded by that institution to the network of Long Duration Research - PELD 22 as area studies.

Architectural Terracotta (ATC) is one of the most common materials in excavations from the Roman period. These ceramic building materials are an essential component of construction. Some of these pieces show potter´s marks, of different categories, that allow access to the production world of these materials. This investigation is a first typological classification of the 1216 marks from ATC materials, collected from 41 archaeological sites in Bracara Augusta (Braga, Portugal). Most of the marks were collected from the domus of Carvalheiras, one of the most emblematic archaeological sites of the city, currently under a musealization process. With this work it was possible to correlate the studied marks with specific terracotta types (shapes), context distribution and associated chronologies. The results suggested an organized and dynamic production, and an open-market, supported by numerous officinae, certainly of different sizes. Some of them were located near the housing area and reveal the presence of a large number of workers, including women and children. Further approaches on mineralogical, chemical and technological characterization of ATC, linked with stratigraphy, are under development.

Different soil managements evidence soil properties, contributing positively or negatively to its quality. A study was conducted in the city of Martins, Rio Grande do Norte (RN) state, in four cultivated areas: corn intercropped with beans (CICB), cassava monocrop (CAMO), bean monocrop (BEMO) and native forest (NF, considered as the original soil condition). This study aimed to evaluate changes in the chemical properties of an Oxisol in function of different agricultural uses (N, P, K+, Ca2+, Mg2+, Na1+, Al3+, pH, EC, H+Al, BS, V, CEC, t, m, OM and ESP) and the distinction of environments using multivariate analysis. The sampling was performed up to 30 cm deep. Soil pH values were kept close to 5.5, except for the area with corn intercropped with beans, whose values were higher than 7.0. Corn intercropped with beans had the highest concentrations of K+, Na+ and Ca2+ on the soil, with a direct impact on base sum. Different uses modified soil chemical properties. Corn intercropped with beans differs from the other treatments due to the addition of solid waste to the soil. Principal component analyses showed pH and exchangeable bases are the most sensitive indicators of environment separation.

Abstract: The pronounced dry season determines the characteristics of the semiarid region of Brazil. Numerous small reservoirs are built to overcome this condition, accumulating multiple uses and causing important changes in the landscape and the local biota. Considering the limited amount of information about the malacofauna of reservoirs, mainly in the Northeast region of the country, this inventory provides a list of mollusks from three important reservoirs located in the city of São Julião, state of Piauí. The collections were carried out monthly between May/2017 and April/2018, sampling a total of 11,149 mollusks, corresponding to the species Melanoides tuberculata (Müller, 1774) (n = 9,724), Biomphalaria straminea (Dunker, 1848) (n = 1,361) and Pomacea lineata (Spix, 1827) (n = 64). The richness of mollusks from the three reservoirs was low, similar to those described in studies conducted in other regions of Northeast Brazil. There was a significant difference in the abundance of M. tuberculata and B. straminea among the studied reservoirs. These environments are not connected and are installed in urban and rural areas, presenting different ecological conditions. The relationship between the human population and the reservoirs, associated with the lack of sanitation, increases the risks of spreading waterborne diseases besides the development of environmental imbalance by the introduction of exotic species.

The Court of Appeals of New York held, in Council of the City of New York u. Giuliani, slip op. 02634, 1999 WL 179257 (N.Y. Mar. 30, 1999), that New York City may not privatize a public city hospital without state statutory authorization. The court found invalid a sublease of a municipal hospital operated by a public benefit corporation to a private, for-profit entity. The court reasoned that the controlling statute prescribed the operation of a municipal hospital as a government function that must be fulfilled by the public benefit corporation as long as it exists, and nothing short of legislative action could put an end to the corporation's existence.In 1969, the New York State legislature enacted the Health and Hospitals Corporation Act (HHCA), establishing the New York City Health and Hospitals Corporation (HHC) as an attempt to improve the New York City public health system. Thirty years later, on a renewed perception that the public health system was once again lacking, the city administration approved a sublease of Coney Island Hospital from HHC to PHS New York, Inc. (PHS), a private, for-profit entity.
