1. Impact of artificial lighting on the ecosystem / Influência da iluminação artificial sobre a vida silvestre: técnicas para minimizar os impactos, com especial enfoque sobre os insetos
The impact of light pollution on man and on the ecosystem is a rising concern among ecologists however, in the same time the human population is demanding more lighting for safety and comfort. In order to satisfy human lighting needs with a minimum impact on the ecosystem, manly on insects, we tested commercial equipments using different types of lights and

2. Desenvolvimento e avaliaÃÃo de um protÃtipo de filtro de tela auto-limpante / Development and evaluation of an autocleaning screen filter prototype.
Ensaios de resistÃncia à pressÃo, perda de carga e capacidade de remoÃÃo de sÃlidos foram realizados em trÃs protÃtipos de filtro de tela autolimpante fabricados em PVC, com o objetivo de avaliar e caracterizar o desempenho dos mesmos. Pelos resultados obtidos, pÃde-se verificar que os protÃtipos operaram satisfatoriamente com pressÃes de serviÃo

3. Utilização de mantas não tecidas como elemento filtrante em sistemas de irrigação localizada
The objective of this work was to evaluate the efficiency of non woven synthetic fabrics on algae removal from water used in trickle and drip irrigation systems. For the evaluation of the non woven synthetic fabrics, the assays have been divided in three stages: in the first stage eight types of synthetic fabrics were evaluated in relation to the head loss e

4. Application of a DNA Hybridization–Hydrophobic-Grid Membrane Filter Method for Detection and Isolation of Verotoxigenic Escherichia coli
Verotoxigenic Escherichia coli (VTEC) strains were isolated from food and animal fecal samples by using PCR to screen for the presence of VTEC after broth enrichment and then filtering VTEC-positive cultures through hydrophobic-grid membrane filters (HGMFs) which were incubated on MacConkey agar. The filters were probed with a digoxigenin-labeled PCR product

5. A 3.5 genome equivalent multi access YAC library: construction, characterisation, screening and storage.
The construction of a yeast artificial chromosome (YAC) primary gridded library of 35,000 clones from human lymphoblastoid (48,XXXX) cell line DNA is described. The average YAC size is approximately 350kb representing a greater than 3.5 times coverage of the genome. The library is stored at -70 degrees C as gridded clones on nylon filters impregnated with 20

6. Mutational analysis of ligand binding activity of beta 2 adrenergic receptor expressed in Escherichia coli.
A novel in situ screening procedure was used to identify neutral mutations in the human beta 2 adrenergic receptor (beta 2AR). The coding region of the human beta 2AR gene was subcloned under transcriptional control of an inducible T7 promoter and used to transform Escherichia coli. Colonies expressing the beta 2AR bound the radiolabeled antagonist [125I]iod

7. Nucleic acid spot hybridization: rapid quantitative screening of lymphoid cell lines for Epstein-Barr viral DNA.
A simple nucleic acid hybridization method to screen numerous samples of eukaryotic cells rapidly for their Epstein-Barr virus (EBV) DNA content is described. Whole cells are spotted on nitrocellulose filters and their DNA is denatured and fixed to the filter. The resultant DNA spots are hybridized to nick-translated EBV DNA and the extent of hybridization i

8. New Mutants of Saccharomyces Cerevisiae Affected in the Transport of Proteins from the Endoplasmic Reticulum to the Golgi Complex
We have isolated new temperature-sensitive mutations in five complementation groups, sec31-sec35, that are defective in the transport of proteins from the endoplasmic reticulum (ER) to the Golgi complex. The sec31-sec35 mutants and additional alleles of previously identified sec and vacuolar protein sorting (vps) genes were isolated in a screen based on the

9. Detection of Duck Hepatitis B Virus DNA on Filter Paper by PCR and SYBR Green Dye-Based Quantitative PCR
Duck hepatitis B virus (DHBV) belongs to the Hepadnaviridae family, which includes human Hepatitis B virus (HBV) and Woodchuck hepatitis virus. It is widely distributed in wild and domestic ducks due to congenital transmission. HBV is a worldwide health problem, with carriers at risk of developing cirrhosis and liver cancer.

10. Anti-poly(A) polymerase antibodies in sera of tumor-bearing rats and human cancer patients.
Poly(A) polymerase (polynucleotide adenylyltransferase; ATP:polynucleotide adenylyltransferase, EC 2.7.7.19) was covalently linked to diazobenzyloxymethyl-filters and used to screen the sera from a number of tumor-bearing rats and human cancer patients for antibodies to poly(A) polymerase. Sera from rats that had been inoculated with any of several Morris he

11. Isolation of lysosomal α-mannosidase mutants of Chinese hamster ovary cells
A method is presented for detection of lysosomal hydrolase activity in situ in colonies of Chinese hamster ovary cells. This method was used to screen for mutants deficient in lysosomal α-mannosidase. Mutagenized cells were replicated onto filter papers [Esko, J. D. & Raetz, C. R. H. (1978) Proc. Natl. Acad. Sci. USA 75, 1190-1193] and allowed to divide for

12. Construction of a BAC Contig Map of Chromosome 16q by Two-Dimensional Overgo Hybridization
We have used sequence-based markers from an integrated YAC STS-content/somatic cell hybrid breakpoint physical map and radiation hybrid maps of human chromosome 16 to construct a new sequence-ready BAC map of the long arm of this chromosome. The integrated physical map was generated previously in our laboratory and contains 1150 STSs, providing a marker on a
