Assessment of fungal contamination in a Portuguese maternity unit

A descriptive study was developed to monitor air fungal contamination in one Portuguese maternity. Sixty air samples were collected through impaction method. Air sampling was performed in food storage facilities, kitchen, food plating, canteen, pharmacy, sterilization areas, genecology wards, intensive care unit, operating rooms, urgency and also, outside premises, since this was the place regarded as reference. Besides air samples, forty three samples were collected by swabbing the surfaces using a 10 by 10 cm square stencil. Simultaneously, temperature, relative humidity and particles counting (PM10) were registered. Twenty three species of fungi were identified in air, being the two most commonly isolated the genera Penicillium (41,5%) and Cladosporium (28,4%). Regarding yeasts, only Rhodotorula sp. (45,2%), Trichosporon mucoides (51,6%) and Cryptococcus neoformans (3,2%) were found. Thirteen species of fungi were identified in surfaces, being the most frequent the Penicillium genus (91,6%). Concerning yeasts found in surfaces, four species were identified being Rhodotorula sp. (29,1%) the most frequent. There was no coincidence between prevailing genera indoors and outside premises. Moreover, some places presented fungal species different from the ones isolated outside. In the inside environment, Aspergillus species were isolated in air and surfaces. There was no significant relationship (p>0,05) between fungal contamination and the studied environmental variables. Keywords: air, surfaces, fungal contamination, environmental variables, maternity.

Comparison of fungal contamination between hospitals and companies food units

A descriptive study was developed to compare air and surfaces fungal contamination in ten hospitals’ food units and two food units from companies. Fifty air samples of 250 litres through impaction method were collected from hospitals’ food units and 41 swab samples from surfaces were also collected, using a 10 by 10 cm square stencil. Regarding the two companies, ten air samples and eight surface samples were collected. Air and surface samples were collected in food storage facilities, kitchen, food plating and canteen. Outdoor air was also collected since this is the place regarded as a reference. Simultaneously, temperature, relative humidity and meal numbers were registered. Concerning air from hospitals’ food units, 32 fungal species were identified, being the two most commonly isolated genera Penicillium sp.

Estudo de caso: minimização e reúso de água em shopping center da região sul do Brasil

The main issues related to water conservation in urban centers are the increase in water supply cost, demand growth, pollution and differences in the distribution of water resources. Water conservation, the controlled and efficient use of water, includes both measures as reasonable means of water reuse. Thus, conservation practices are an effective way to meet demand and supply water to new activities and users without jeopardizing the supplying water bodies and preserving the natural environment. This study aims to examine the water management of a shopping mall and the use of rainwater harvesting combined with greywater reuse. For buildings in general, water loss is common due to leaks in the hydraulic and restroom equipment. These losses, which are caused by a high volume of water used and wasted in the system, are often the result of design errors, incorrect maintenance procedures and users' bad habits In southern Brazil, where there is rainfall almost all year long, water shortages occasionally occur, particularly in some winter mouths. One difficulty that appears on rainwater studies is the proper determination of rainwater volume that can be used to address water supply systems. In this work, the simulation method was used to determine this volume. Thus, simulations with the following variables: rainfall, catchment area and water consumption were performed. For mall's hydraulic systems, segmented alternatives are adopted. That is, focusing on the use of rainwater or greywater reuse. Other alternatives of effluent reuse have been slightly discussed due to sanitary issues, those are effluents from toilets and kitchen sinks. The adoption of greywater may be feasible if there is a significant flow of greywater to comply water demand for toilet flushing. The inspections made in this study found that the quantity of sinks was insufficient to supply an adequate amount of water to toilets and urinals. The greywater reuse system was found to be infeasible in terms of demand and supply of water. Conversely, the rainwater harvesting system was entirely feasible and easily supplied water to all restrooms and contributed to the cooling of the air conditioning system with a short payback period. One of the challenges of this work was the need to compare the actual water consumption with a water consumption parameter used in buildings. Thus, a method that addresses the generation of specific consumption indexes for specific activity (like a mall) was used. The water consumption indices showed that this mall has a satisfactory water management program.

Creating a modern home: homeowners in post-war suburban Glasgow, 1945-1975

This thesis examines how married couples bought and created a modern home for their families in suburban Glasgow between 1945-1975. New homeowners were on the cusp of the middle-classes, buying in a climate of renters. As they progressed through the family lifecycle women’s return to work meant they became more comfortably ensconced within the middle-classes. Engaged with a process of homemaking through consumption and labour, couples transformed their houses into homes that reflected themselves and their social status. The interior of the home was focused on as a site of social relations. Marriage in the suburbs was one of collaboration as each partner performed distinct gender roles. The idea of a shared home was investigated and the story of ‘we’ rather than ‘I’ emerged from both testimony and contemporary literature. This thesis considers decision-making, labour and leisure to show the ways in which experiences of home were gendered. What emerged was that women’s work as everyday and mundane was overlooked and undervalued while husband’s extraordinary contributions in the form of DIY came to the fore. The impact of wider culture intruded upon the ‘private’ home as we see they ways in which the position of women in society influences their relationship to the home and their family. In the suburbs of post-war Glasgow women largely left the workforce to stay at home with their children. Mothers popped in and out of each other houses for tea and a blether, creating a homosocial network that was sociable and supportive unique to this time in their lives and to this historical context. Daily life was negotiated within the walls of the modern home. The inter-war suburbs of Glasgow needed modernising to post-war standards of modern living. ‘Modern’ was both an aesthetic and an engagement with new technologies within the house. Both middle and working-class practices for room use were found through the keeping of a ‘good’ or best room and the determination of couples to eat in their small kitchenettes. As couples updated their kitchen, the fitted kitchen revealed contemporary notions of modern décor, as kitchens became bright yellow with blue Formica worktops. The modern home was the evolution of existing ideas of modern combined with new standards of living. As Glasgow homeowners constructed their modern home what became evident was that this was a shared process and as a couple they placed their children central to all aspects of their lives to create not only a modern home, but that this was first and foremost a family home

The Shrine of ʿAbd al-Qādir al-Jīlānī in Baghdad & the Shrine of ʿAbd al-ʿAzīz al-Jīlānī in ʿAqra: Mapping the multiple orientations of two Qādirī Sufi shrines in Iraq

This thesis charts the stakeholder communities, physical environment and daily life of two little studied Qādiriyya Sufi shrines associated with Shaikh ʿAbd al-Qādir al-Jīlānī (1077 – 1165 AD), a 12th century Ḥanbalī Muslim theologian and the posthumous founder of one of the oldest Sufi orders in Islam. The first shrine is based in Baghdad and houses his burial chamber; and the second shrine, on the outskirts of the city of ‘Aqra in the Kurdish region of northern Iraq, is that of his son Shaikh ʿAbd al-ʿAzīz (died 1206 AD). The latter was also known for lecturing in Ḥanbalī theology in the region, and venerated for this as well as his association with Shaikh ʿAbd al-Qādir. Driven by the research question “What shapes the identity orientations of these two Qādiriyya Sufi shrines in modern times?” the findings presented here are the result of field research carried out between November 2009 and February 2014. This field research revealed a complex context in which the two shrines existed and interacted, influenced by both Sufi and non-Sufi stakeholders who identified with and accessed these shrines to satisfy a variety of spiritual and practical needs, which in turn influenced the way each considered and viewed the two shrines from a number of orientations. These overlapping orientations include the Qādirī Sufi entity and the resting place of its patron saint; the orthodox Sunnī mosque with its muftī-imams, who are employed by the Iraqi government; the local Shīʿa community’s neighbourhood saint’s shrine and its destination for spiritual and practical aid; and the local provider of welfare to the poor of the city (soup kitchen, funeral parlour and electricity-generation amongst other services). The research findings also revealed a continuously changing and adapting Qādirī Sufi scene not immune from the national and regional socio-religio-political environments in which the two shrines exist: a non-Sufi national political class vying to influence and manipulate these shrines for their own purposes; and powerful national sectarian factions jostling to do the same. The mixture of stakeholders using and associating with the two shrines were found to be influential shapers of these entities, both physically and spiritually. Through encountering and interacting with each other, most stakeholders contributed to maintaining and rejuvenating the two shrines, but some also sought to adapt and change them driven by their particular orientation’s perspective.

Da cozinha ao terreiro em Mutamba da Caieira (RN) : cotidiano, espaço doméstico e sociabilidade

In this work we thought about the social use of the domestic space and, specifically, the space destined to the preparation of food. The kitchen is a creative space of social relationships. There the families exchange daily interaction with the neighbors, in a collective of the space reserved to the making of food. Our empiric research was in the Mutamba da Caieira community, located in the county of Assu (RN). The data was collected through the etnographic method aided by the photographic resources. In the discussion, we delimitated at the house three types of kitchens: one reserved to the family, another kitchen in the terrace and yet another kitchen in the yard. They are kitchens that link amongst themselves with activities and differentiated temporalities. In the daily social exchange, the kitchen imposes itself as a social space through the conditions that it offers for the production of the foods, the circulation of domestic objects, the communication of knowledge around the cookery, operating a group of symbolic and ritual actions combined with appropriate techniques for the transformation of the foods. The study reveals that the domestic chores accomplished amon relatives and friends form webs of intracommunitary relationships in the use of the three kitchens, and that the social network is updated in a singular moment that usually happens in the community, the Game of Pacará

Nervous Kitchens: Critical Readings of Black Women's Food Practices in The Soul Food Imaginary

Nervous Kitchens intervenes in the story of soul food by treating the kitchen as a central site of instability. These kitchens reveal and critique their importance to constructions of Black womanhood. Utilizing close readings of Black women’s culinary practices in popular televisual kitchens and archival analysis of USDA domestic reforms, the project locates sites that challenge how we oversimplify soul food as a Black cultural product. These oversimplifications come through what I term the soul food imaginary. This term underscores how the cuisine is tangible (i.e., how dishes are made) but also the ways that histories of enslavement, migration, and domesticity are disseminated through fictionalized representations of Black women in the kitchen offering comfort through food. The project explores how images of these kitchens adhere to and diverge from the imaginary's four conventions: (1) Soul food originates in enslavement where master’s scraps became mama’s meal time; (2) Soul food is not healthy food; (3) Soul food moves South to North uninterrupted during the Great Migration and is evidence of and fuel for struggle, survival, and transformation; and 4) Black women cook it the best, naturally, and alone in the kitchen.

Avaliação do potencial de formigas (Hymenoptera: formicidae) como vetores mecânicos de bactérias do gêneroSstaphylococcus no ambiente hospitalar.

In a hospital environment, these bacteria can be spread by insects such as ants, which are characterized by high adaptability to the urban environment. Staphylococcus is a leading cause of hospital infection. In Europe, Latin America, USA and Canada, the group of coagulase negative staphylococci (CoNS) is the second leading cause of these infections, according to SENTRY (antimicrobial surveillance program- EUA). In this study, we investigated the potential of ants (Hymenoptera: Formicidae) as vehicle mechanics of Staphylococcus bacteria in a public hospital, in Natal-RN. The ants were collected, day and night, from June 2007 to may 2008, in the following sectors: hospitals, laundry, kitchen, blood bank. The ants were identified according to the identification key of Bolton, 1997. For the analysis of staphylococci, the ants were incubated in broth Tryptic Soy Broth (TSB) for 24 hours at 35 º C and then incubated on Mannitol Salt Agar. The typical colonies of staphylococci incubated for 24 hours at 35 ° C in Tryptic Soy Agar for the characterization tests (Gram stain, catalase, susceptibility to bacitracin and free coagulase). The identification of CoNS was performed through biochemical tests: susceptibility to novobiocin, growth under anaerobic conditions, presence of urease, the ornithine decarboxylation and acid production from the sugars mannose, maltose, trehalose, mannitol and xylose. The antimicrobial susceptibility examined by disk-diffusion technique. The technique of Polymerase Chain Reaction was used to confirm the presence of mecA gene and the ability to produce biofilm was verified by testing in vitro using polystyrene inert surface, in samples of resistant staphylococci. Among 440 ants, 85 (19.1%) were carrying coagulase-negative staphylococci (CoNS) of the species Staphylococcus saprophyticus (17), Staphylococcus epidermidis (15), Staphylococcus xylosus (13), Staphylococcus hominis hominis (10), Staphylococcus lugdunensis (10), Staphylococcus warneri (6), Staphylococcus cohnii urealyticum (5), Staphylococcus haemolyticus (3), Staphylococcus simulans (3), Staphylococcus cohnii cohnii (2), and Staphylococcus capitis (1). No Staphylococcus aureus was found. Among the isolates, 30.58% showed resistance to erythromycin. Two samples of CoNS (2.35%), obtained from the ant Tapinoma melanocephalum collected in the post-surgical female ward, S. Hominis hominis and S. lugdunensis harbored the mecA gene and were resistant to multiple antibiotics, and the specie S. hominis hominis even showed to be a biofilm producer. This study proves that ants act as carriers of multidrug-resistant coagulase-negative Staphylococci and biofilm producers and points to the risk of the spreading of pathogenic microorganisms by this insect in the hospital environment

Petrofac International Limited: el mercadeo interno, una estrategia efectiva en el manejo de personal

Como futuros administrados es importante recordar que nuestra función no será únicamente crear una empresa y generar constantemente ingresos. Esto es una de tantas tareas que tiene una persona que se encamina por crear o ser parte de una empresa, sea grande o pequeña siempre existirán variables que con los años se han convertido más y más indispensables en los procesos de este recorrido. El tema principal de nuestro estudio de caso es entender el concepto del endomarketing o como muchos lo conocen marketing interno; en pocas palabras es algo que por años se ha visto su efectividad en la productividad y satisfacción de los empleados. Google es una de las multinacionales más grandes del mundo, que el ultimo reconocimiento fue por parte de uno de los ranking más influyentes “The World’s Billionaries” ocupando como el CEO de la compañía Larry Page el puesto #12 , que por años ha sabido invertir en su recurso más importante que son sus empleados. En una entrevista con la revista Fortune, Larry exclama que “es importante que la empresa sea una familia, que las personas sientan que son parte de la empresa, y que la empresa es como una familia para ellos. Cuando se trata a las personas de esa manera, se obtiene una mejor productividad”. Con este pequeño ejemplo e idea de cómo una de las marcas más influyentes en el mundo ha fortalecido su mejor recurso por años el cual le ha remunerado con el éxito que tiene hoy en día. Entonces es como el mercadeo interno o endomarketing siendo uno de los conceptos tratados en el mercadeo en general hoy en día, logrando meterse como un modelo de negocio en la mayoría de empresas que existen hoy. Este es uno de los motivos que nos motivó para desarrollar este estudio de caso que verán a continuación, el cual se basa en la investigación y análisis de variables que comprenden a la empresa Petrofac, y si bien ha sabido implementar el concepto en sus procesos diarios. El estudio de caso describe como a través de los años ha sabido implementar con éxito la herramienta de evaluación y análisis del mercado interno a los empleados que constituyen hoy en día Petrofac International Limited. Abarcaremos primero con los objetivos del estudio, seguido del inicio y crecimiento de la empresa en los últimos años, en que países tiene presencia y cuáles son sus proyectos más importantes hoy en día. El estudio de caso será implementado por un tipo de investigación descriptiva, que con la recopilación de suficiente información tanto cuantitativa como cualitativa nos ira fortaleciendo la hipótesis principal, usaremos datos estadísticos que serán recopilados de encuestas, entrevistas y focus group. Al final con el análisis y a las conclusiones que lleguemos se busca demostrar el impacto positivo que ha tenido los empleados de diferentes países y de diferentes culturas que poco a poco han influenciado a la empresa para alcanzar el éxito que ha logrado hasta ahora, y de la misma forma como la empresa ha influenciado en cada una de las vidas de estas personas sin importar el lugar en el que estén laborando, siempre la empresa busca que se sientan parte de ella. Como resultados generales, se obtienen argumentos que sustentan que la implementación del mercadeo interno le permite a la empresa generar ventajas competitivas y dinámicas, que son desarrolladas internamente para un futuro reflejarlas ante los clientes externos. El estudio permitió concluir que el mercadeo interno debe ser una estrategia de comunicación dentro de una empresa convirtiéndose de primera necesidad para la compañía, pues los beneficios que genera son cada vez más necesarios para cada área que abarca el negocio.

Electronic structure and magnetism of Mn-doped GaSb for spintronic applications: A DFT study

We have carried out first-principles spin polarized calculations to obtain comprehensive information regarding the structural, magnetic, and electronic properties of the Mn-doped GaSb compound with dopant concentrations: x¼0.062, 0.083, 0.125, 0.25, and 0.50. The plane-wave pseudopotential method was used in order to calculate total energies and electronic structures. It was found that the MnGa substitution is the most stable configuration with a formation energy of 1.60 eV/Mn-atom. The calculated density of states shows that the half-metallic ferromagnetism is energetically stable for all dopant concentrations with a total magnetization of about 4.0 lB/Mn-atom. The results indicate that the magnetic ground state originates from the strong hybridization between Mn-d and Sb-p states, which agree with previous studies on Mn-doped wide gap semiconductors. This study gives new clues to the fabrication of diluted magnetic semiconductors
