Engineering geology of the Wrexham Area

This report describes the engineering geology of the Wrexham district comprising an area of 225 km2 contained within National Grid 10 km squares SJ 35 25 (Quadrants KE and SE) and 34 (Quadrants NW and NE). The study was undertaken as part of an applied geology mapping project of the area by the British Geological Survey (BGS), part funded by the Department of the Environment ( Contract No. PECD] 7/ 1/ 290). The report appertaining to the project as a whole provides information on stratigraphy and mineral reserves and contains the Thematic Element Maps re€erred to within this report

Stoke-on-Trent: a geological background for planning and development

This study, carried out between 1988 and 1990, was commissioned by the Department of the Environment (DOE) and funded jointly by the Department and the British Geological Survey (BGS). Its main aim was to make a synthesis of geological data relevant to planning of land-use and development in the Stoke-on-Trent area. This report is specifically written for planners and there has been an attempt to avoid complex geological terms. Besides text illustrations the report includes ten thematic maps at a common scale of 1 :25 000. An additional volume concentrates on engineering geology for site investigation companies. Seven further short reports feature geological details of separate 1: 10 000 sheets, couched in more technical language

Farelo de gérmen de milho desengordurado na dieta de poedeiras comerciais de 28 a 44 semanas de idade Defatted corn germ meal in diets for laying hens from 28 to 44 weeks of age

Um experimento foi conduzido para avaliar os efeitos da inclusão de farelo de gérmen de milho desengordurado na dieta de galinhas de 28 a 44 semanas de idade. Foram utilizadas 240 poedeiras Hy-Line W36 distribuídas em delineamento inteiramente casualizado, com seis níveis de farelo de germen de milho desengordurado (0, 6, 12, 18, 24 e 30%),cada um com cinco repetições de oito aves. No período experimental, que durou quatro ciclos de 28 dias, foram avaliados os parâmetros de desempenho das aves (consumo de ração, produção de ovos, peso médio do ovo, massa de ovo e conversão alimentar) e de qualidade dos ovos (gravidade específica, índice de pigmentação da gema, porcentagem de gema e albúmen, porcentagem e espessura da casca e unidade haugh). Os níveis de farelo de gérmen de milho desengordurado tiveram efeito linear negativo sobre o consumo de ração e o índice de pigmentação da gema e efeito quadrático sobre a conversão alimentar. A inclusão de farelo de gérmen de milho desengordurado na dieta não influenciou as outras variáveis estudadas. O farelo de gérmen de milho desengordurado pode ser incluído em níveis de até 21,2% em rações para galinhas poedeiras.<br>This experiment was conducted to evaluate the effect of including defatted corn germ meal in diets for laying hens. It was assigned two hundred and forty laying hens to a randomized design, with six diets and five replicates of eight hens per diet. Experimental diets were formulated by inclusion of defatted corn germ meal at 0, 6, 12, 18, 24 and 30% level. The period experiment was carried out for four 28-day cycles and performance (feed intake, egg production, egg weight, egg mass and feed conversion) and the egg quality (egg specific gravity, yolk color, yolk and albumen percentages, shell percentages, shell thickness and Haugh unity) were the evaluated parameters. Negative linear effect was observed for feed intake and yolk pigmentation by increasingly including defatted corn germ meal in diets for laying hens. Quadratic effect of defatted corn germ meal for feed conversion was also observed. No statistical differences were observed for any other parameters. Defatted corn germ meal can be included at 21.2% in laying hens diets
