TL;DR: In all cases, rate of response was higher in the variable-interval 30 sec component, but the discrepancy in the rate produced by the two schedules tended to be greatest when the duration of component presentation was brief.
Abstract: Pigeons were trained on a multiple variable-interval 30-sec, variable-interval 90-sec schedule with each component presented alternately for an equal (on the average) duration. This average duration of exposure to each component was varied from 5 to 300 sec. The main concern was with rate of response in the variable-interval 30-sec component relative to rate of response in the variable-interval 90-sec component. In all cases, rate of response was higher in the variable-interval 30 sec component, but the discrepancy in the rate produced by the two schedules tended to be greatest when the duration of component presentation was brief. The mean proportion of responses emitted during the variable-interval 30-sec component (responses in variable-interval 30-sec component divided by total responses) varied from about 0.60 to 0.71, where 0.75 would be expected on the basis of a matching rule, and 0.59 was that obtained by Lander and Irwin (1968). These results are in agreement with data reported by Shimp and Wheatley (1971) from a similar experiment.

TL;DR: Nine species of ophiuroids were collected in various habitats from the mid-littoral and upper infralittoral on the northern coast of the State of São Paulo, Brazil and feeding observations have shown Axiognathus squamatus to capture its food by mucous nets.
Abstract: Nine species of ophiuroids — Amphipholis januarii, Axiognathus squamatus, Hemipholis clongata, Ophiocnida scabriuscula, Ophiactis lymani, Ophiactis savignyi, Ophionereis reticulata, Ophioderma appressum and Ophiothrix angulata —were collected in various habitats from the mid-littoral and upper infralittoral on the northern coast of the State of Sao Paulo, Brazil. The abundance of 6 species occurring in 28 species of algae was investigated. A total of 220 samples was collected at monthly intervals from April, 1969 to May, 1970. The distributional pattern of the populations, as determined by Mobisita's index, shows aggregation of the ophiuroids. No ophiuroid species was limited to one algal species. Each species prefers certain algal species and/or a different level on the shore. The most abundant species on algae was Ophiactis lymani, with a maximum density of 1,510 individuals/100 ml of algae. Four species of ophiuroids occurred inside sponges. The most abundant species in sponges was O. savignyi, with a maximum density of 1,892 individuals/100 g of dry sponge. Two species of ophiuroids occurred inside the bryozoan Schizoporella unicornis. Feeding observations have shown Axiognathus squamatus to capture its food by mucous nets. Decapod crustaceans fed on ophiuroids in aquaria. The copepod Thespesiopsyllus sp. was found in the body cavity of the 2 Ophiactis species. Simultaneous sexual and asexual reproduction were abserved in O. savignyi.

TL;DR: Data for Apis mellifera indicate that the P-3 proteins and one esterase enzyme are controlled by two genes, P- 3 and Est, with two alleles each, which are different in the two subspecies.
Abstract: Data for Apis mellifera indicate that the P-3 proteins and one esterase enzyme are controlled by two genes, P-3 and Est , with two alleles each. The frequency of the P-3 alleles is different in the two subspecies ( adansonii and ligustica ), that for P-3 F in Italian bees being 46.9% and in African 0.5%. The frequency of Est F is 2.8% in both populations. The Est locus has two codominant alleles and the locus P-3 has two incompletely dominant alleles; the heterozygote P-3 S /P-3 F shows only an intermediate band. The two loci are not genetically linked.

TL;DR: O estudo evidenciou that a mortalidade por acidentes de veiculo a motor e alta, maior no sexo masculino, aumenta com a idade, sendo that o maior coeficiente foi para maiores de 60 anos.
Abstract: Foram estudadas algumas caracteristicas dos obitos por acidentes de trânsito de veiculos a motor, no municipio de Sao Paulo, ocorridos entre 1.° de janeiro a 31 de dezembro de 1970. Todas as caracteristicas do falecido e do acidente foram coletadas a partir dos dados registrados nos laudos de necropsias existentes no Instituto Medico Legal. O estudo evidenciou que a mortalidade por acidentes de veiculo a motor e alta, maior no sexo masculino, aumenta com a idade, sendo que o maior coeficiente foi para maiores de 60 anos. A zona da cidade com maior numero de acidentes e a zona Sul, existindo areas (distritos policiais) e vias publicas preferenciais quanto a ocorrencia, em todas as 4 zonas do municipio; a maior ocorrencia de acidentes foi aos sabados e domingos; os pedestres compreendem a grande maioria dos falecidos; proporcao apreciavel dos falecidos recebeu atendimento hospitalar apos o acidente. Foram relacionados tambem o numero total de acidentes, vitimas e mortes mostrando que para cada 100 acidentes ocorreram 62,50 vitimas e 5,13 mortes, e para cada 100 vitimas, 18, 22 mortes.

TL;DR: Descreve-se a presenca de foco de leishmaniose tegumentar no vale do rio Moji-Guacu, em regiao comum aos municipios de Luiz Antonio, Sao Carlos, Rincao e Santa Rita do Passa Quatro, no Estado of Sao Paulo, Brasil.
Abstract: Descreve-se a presenca de foco de leishmaniose tegumentar no vale do rio Moji-Guacu, em regiao comum aos municipios de Luiz Antonio, Sao Carlos, Rincao e Santa Rita do Passa Quatro, no Estado de Sao Paulo, Brasil. Os casos humanos apresentavam formas clinicas caracterizadas por lesoes ulcero-vegetantes, de evolucao lenta e pobres em parasitos. As investigacoes sobre infeccao natural em animais silvestres levou ao isolamento de roedores, de tres cepas em cultura, duas procedentes de Akodon arviculoides e uma de Oryzomys nigripes. As provas de inoculacao em hamsters foram, ate o momento, positivas para duas delas, mas com evolucao lenta, com manifestacoes clinicas muito discretas e pobres em parasitos. Pelos dados disponiveis ate o momento, parece tratar-se de cepas filiaveis a raca "lenta", a qual se atribui papel na etiologia da forma cutaneo-mucosa da leishmaniose.

TL;DR: It is verified that the proport ion of r R N A genes does not change during a period of time corresponding to almost two cycles of D N A replication at the end of larval life.
Abstract: Two facts make it important to determine whether the proportion of ribosomal R N A (rRNA) 1 genes in salivary glands of Rhynchoscza~a angelae varies throughout the end of the last (fourth) instar of larval development, namely: (a) In this instar, during the appearance of \" D N A puffs,\" it is possible to observe many micronucleoli around the chromosomes (1). Perhaps the micronucleoli maybe ascribed to an extra synthesis of ribosomal D N A (rDNA), in analogy to what has been proposed in Hybosczara, to explain similar microbodies (2). (b) In s~tu hybridization experiments showed that the r R N A genes are located mainly at the heterochromatic ends of chromosomes X and C (3). As heterochromatic regions are less active in replication in polytene chromosomes (4-6), one would suspect an under-replication of the r R N A genes during polytenization, similar to what has been observed in Drosophila hyde~ (7). However, this was not observed for Rhynchosczara (18). To test both these hypotheses, we hybridized r R N A with salivary gland D N A from larvae of different ages at the end of larval life An alteration in the hybridization level during the polytenizadon wouId indicate either an under-replication or amplification of the r R N A genes. In this paper, we verified that the proport ion of r R N A genes does not change during a period of t ime corresponding to almost two cycles of D N A replication at the end of larval life. I t was also observed that the number of r R N A genes in ovary

TL;DR: A formacao e a atuacao do especialista em educacao em saude, que integra a equipe de saude escolar, foi objetivada abordando aspectos do Curso de Educacao en Saude na Escola, ministrado na Faculdade de Saude Publica da Universidade de Sao Paulo, Brazil as discussed by the authors.
Abstract: Sao caracterizadas as responsabilidades da escola na area da saude e apresentados os principios basicos que devem fundamentar o programa de educacao em saude na escola, seus objetivos e areas. A formacao e a atuacao do especialista em educacao em saude, que integra a equipe de saude escolar, foi objetivada abordando aspectos do Curso de Educacao em Saude na Escola, ministrado na Faculdade de Saude Publica da Universidade de Sao Paulo, Brasil.
TL;DR: The radula of “Acteon” punctostriatus from Chesapeake Bay shows that the species comes under Rictaxis Dall, 1871, hence the species called punctostRIatus from Brazil, a true Acteon, receives a new name, Acteon pelecais.
Abstract: Seventeen species of opisthobranchs from Chesapeake Bay were studied, 4 Cephalaspidea, 6 Ascoglossa, 5 Doridoidea, and 2 Eolidoidea. The radula of “Acteon” punctostriatus from Chesapeake Bay shows that the species comes under Rictaxis Dall, 1871, hence the species called punctostriatus from Brazil, a true Acteon, receives a new name, Acteon pelecais. Two species of Haminoea, distinguished by a small cylindrial shell, H. succinea, and a larger ovoid shell, H. solitaria, have consistent anatomical features. The generic name of Stiliger has to be replaced by Ercolania due to Baba & Hamatani’s (1970a) redescription of Stiliger ornatus. Alderia harvardiensis is identical with A. modesta which occurs in Finland, California, and Brazil. Hermaea cruciata is redescribed. It differs from H. coirala from Brazil. The substitution of Cargoa for Okenia is unnecessary. Cratena kaoruae Marcus, 1957, from Brazil is a synonym of C. pilata. Tenellia pallida is a junior synonym of T. adspersa (Nordmann, 1845).
TL;DR: In this article, the hindered rotation in cubic fields of various shapes and intensities is studied, and agreement is found between the low-lying rotator levels in a large hindering potential and these of harmonic oscillators localized in the minimum wells of the potential.
Abstract: The hindered rotation in cubic fields of various shapes and intensities is studied. The “Devonshire Model” is extended to include cubic fields being linear combinations of spherical harmonics of order four and six. In contrast to Devonshire's potential, this two parameter manifold of potentials contains some with the energy minima at the 〈110〉 directions. Agreement is found between the low-lying rotator levels in a large hindering potential and these of harmonic oscillators localized in the minimum wells of the potential.
Ein Rotator wird untersucht, der durch verschiedene Felder kubischer Symmetrie behindert wird. Das „Devonshire Modell” wird erweitert, indem kubische Felder betrachtet werden, die Linearkombinationen von Kugelfunktionen vierter und sechster Ordnung sind. Im Gegensatz zum „Devonshire Modell” enthalt diese zweiparametrige Menge von Feldern auch solche, deren Minima in den 〈110〉-Richtungen liegen. Fur hohe Hinderungspotentiale stimmen die tiefenergetischen Zustande des Rotators mit denen von harmonischen Oszillatoren, lokalisiert in den Minima des Potentials, uberein.
TL;DR: The heartwood of Brosimum rubescens Taubert as discussed by the authors contains the 7-hydroxycoumarins 7-demethyl-suberosin (IIa) and xanthyletin (Ia) besides the 7,8-dihydroxycoupmarins brosiparin (IIb), brossiprenin (IVa), and luvangetin(Ic).
TL;DR: In this paper, it was shown that for all Auger recombination quadruplets of states in non-degenerate bands, those which are most probable are also the quadruplets which yield the threshold of impact ionization.
TL;DR: A pesquisa, "Investigacao de Causas Multiplas de Morte", this article, has been published to investigate causas associadas contribuintes.
Abstract: A analise de alguns problemas de saude publica, no que diz respeito as doencas, e feita principalmente atraves de estatisticas de mortalidade. As informacoes obtidas referem-se somente a causa basica de morte. Reconhece-se, porem, que a causa basica nao e suficiente, na maioria das vezes, para adotar medidas preventivas. Para isso, torna-se necessario conhecer as causas associadas contribuintes. Dessa maneira, vem sendo cada vez mais enfatizadas a importância de serem conhecidas as causas multiplas de morte. Descreve-se uma pesquisa, "Investigacao de Causas Multiplas de Morte", que esta sendo levada a efeito em algumas cidades da America Latina a qual servira para estabelecer regras de codificacao e, tambem, de tabulacoes de Causas Multiplas de Morte, tendo-se em vista oferecer subsidios a 9.a Revisao da Classificacao Internacional de Doencas.
TL;DR: Two siblings, a 23-yr-old woman and a 34- yr-old man, with congenital goiter and hypothyroidism were referred to the thyroid clinic for evaluation and both patients were on thyroid extract since early childhood but were mentally retarded.
Abstract: Two siblings, a 23-yr-old woman and a 34-yr-old man, with congenital goiter and hypothyroidism were referred to the thyroid clinic for evaluation. They were on thyroid extract since early childhood and attained normal growth but were mentally retarded. Inbreedings were noted in the family pedigree but no cases of goiter were reported. The BMR was low for both patients and PBI was 1.0 μg and 2.2 μg/100 ml, respectively. T4-I was 1.0 μg and 1.8 μg/100 ml. The perchlorate test was negative. The TRC test was repeatedly negative. The RAI uptake was 3.5% and 6.0% at 24 hr with no response to TSH. Plasma chromatography of iodinated compounds disclosed only iodide and iodoproteins. Traces of T3 + T4 were present in one sairrole. Plasma TSH was very high in both patients. The resting mixed saliva/plasma ratio at 2, 4 and 6 hr after a iv dose of 131I were, respectively, 7.2 and 5.9, 8.7 and 5.9, 7.9 and 6.7 for HCR, and JFCR (normal controls: 27.7–64.3). The gastric juice/plasma ratio was 5.2 and 5.0 seven...
TL;DR: In this article, compounds of general formula Ln(NO 3 ) 3 ·2TMMA and Ln (ClO 4 ), 3 ·4TMMA (Ln La, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y) are described.
TL;DR: Sao apresentado os dados obtidos na investigacao da mobilidade de ninfas e adultos de Triatoma arthurneivai as discussed by the authors.
Abstract: Sao apresentados os dados obtidos na investigacao da mobilidade de ninfas e adultos de Triatoma arthurneivai. As observacoes foram levadas a efeito na localidade denominada Bairro do Arado, municipio de Salto de Pirapora, Estado de Sao Paulo, Brasil. Atraves a marcacao e recaptura durante 24 semanas consecutivas, pode-se observar o comportamento em relacao ao local de soltura e os deslocamentos em direcao a outros ecotopos. Ambas as formas mostraram capacidade de locomocao ativa, embora inferior por parte das ninfas. No entanto, estas tambem revelaram capacidade de vencer distâncias praticamente equivalentes as dos adultos, embora sem poder dispor da capacidade de voo. Os dados permitiram registrar sobrevivencia maior para as ninfas que, em alguns casos, chegou a ser de, pelo menos, 12 semanas.
TL;DR: In this article, a new approach is suggested to calculate the pressure broadening and shift of lines in the microwave and far infrared regions using the semi-classical impact theory, and the results are compared with those of Murphy and Boggs.
TL;DR: An electron microscope study was made of the “cyst-like bodies” (CLBs) previously described in cultures of Trypanosoma conorhini and it is suggested that CLBs are a process of reproduction which involves fusion of epimastigotes, repeated divisions of DNA-containing organelles and organization of daughter epimastsigotes that may be found free within the large central “vacuole” of the CLB.
Abstract: SYNOPSIS. An electron microscope study was made of the “cyst-like bodies” (CLBs) previously described in cultures of Trypanosoma conorhini. It is again suggested that CLBs are a process of reproduction which involves fusion of epimastigotes, repeated divisions of DNA-containing organelles and organization of daughter epimastigotes that, after being completely formed, may be found free within the large central “vacuole” of the CLB. This “vacuole,” it is now evident, results from the fused and muchdilated flagellar reservoirs of parent epimastigotes. Our interpretation of the CLBs and their possible genetic significance are discussed.

TL;DR: A systematic revision of the genus Winthemia Robineau-Desvoidy, 1830 of America north of Mexico is presented, and it is suggested that parasitoid insects are more commonly niche-specific than host-specific.
Abstract: A systematic revision of the genus Winthemia Robineau-Desvoidy, 1830 of America north of Mexico is presented. Twenty-five species are described, figured and keyed. Six new species are described: andersoni, argentifrons, aurifrons, floridensis, sabroskyi and reinhardi. Winthemia antennalis Coquillett does not belong in this genus and its correct placement has not been determined. Published biological information is summarized and new information on several species is added. Evolutionary trends in Winthemia are discussed, and critical morphological details are discussed and figured. The ecological data obtained so far support the observations of Townes (1962) who suggests that parasitoid insects are more commonly niche-specific than host-specific.
TL;DR: In this article, the authors examined populations from the Vale do Ribeira (Sao Paulo State) as far as vitamin A deficiency is concerned and concluded that hipovitaminosis A in this area constitutes a public health problem according to the concept of the Pan-American Sanitary Organization.
Abstract: It was examined populations from the Vale do Ribeira (Sao Paulo State) as far as vitamin A deficiency is concerned. Measurements of serum vitamin A and carotene were carried out. Data from a nutritional survey perfomed by Department of Nutrition, School of Public Health, University of Sao Paulo, in the city of Iguape and the villages of Icapara and Pontal do Ribeira, were used. The results of the nutritional, clinical and biochemical surveys were discussed. It was concluded that hipovitaminosis A in this area constitutes a public health problem according to the concept of the Pan-American Sanitary Organization.
