Flare angles measured with ball gage

Precision tungsten carbide balls measure the internal angle of flared joints. Measurements from small and large balls in the flare throat to an external reference point are made. The difference in distances and diameters determine the average slope of the flare between the points of ball contact

Occurrence of mite Ophionyssus natricis (Acari: Macronyssidae) on captive snakes from Panama

We report for the first time the presence of the snake mite, Ophionyssus natricis (Gervais) (Mesostigmata: Macronyssidae) on captive snakes kept at Panama City, Panama. This occurrence adds a new record to the geographical distribution of O. natricis as well as confirms its high prevalence on captive reptiles. Several Boidae species, Boa constrictor, Epicrates maurus, Corallus ruschenbergerii, Corallus caninus and a Pythonidae, Python regius were found infested with intensities varying from 10 to 2200 mites each. These findings represent the second record of O. natricis for Central America

Mulher Indígena e Cuidados Durante a Gravidez e Puerperio

At the dawn of this 21st century, with an undeniable scenario of great advances in science and technology, we present the reality with which the population of indigenous peoples resists, with urgent modifications and resilient effects to give meaning to the life that corresponds to accept, without succumbing to its uncertain destiny.The original peoples of our America, as in Panama, with the scarce resources that the Ngäbe-Buglé and other indigenous peoples manage to obtain for their survival, make enormous efforts for their survival. So being poor, being indigenous and woman, in a rural area, represents a great challenge to challenge life and the universe.Objective. Present results in relation to research conducted on the topic of indigenous women and their health during pregnancy and the puerperium.Methodology. Review of scientific articles, research conducted in America, in relation to indigenous women and care during pregnancy and puerperium, in the main databases available in health sciences and nursing.Results. Women have access to health services with the characteristics of double disadvantages: being a woman and being indigenous. The meaning that the woman assigns to her care during pregnancy and the puerperium is diverse and is influenced by the cultural component, with practices and beliefs.Conclusions. The health of indigenous women should be considered as a priority in the provision of health services. The Sustainable Development Goal focuses on "Achieving gender equality and empowering all women and girls."En los albores de este siglo XXI, con un indiscutible escenario de grandes avances de la ciencia y la tecnología, se presenta la realidad con la que la población de pueblos originarios resiste, con urgentes modificaciones y efectos resilientes para dar sentido a la vida que le corresponde aceptar, sin sucumbir a su incierto destino.Los pueblos originarios de nuestra América, al igual que en Panamá, con los escasos recursos que logra conseguir para su supervivencia, los Ngäbe-Buglé y otros pueblos indígenas, efectúan ingentes esfuerzos para la supervivencia.

MARIE Measurements and Model Predictions of Solar Modulation of Galactic Cosmic Rays at Mars

Recent data from the MARIE (Martian Radiation Environment Experiment) instrument on board the 2001 Mars Odyssey spacecraft currently in Mars orbit are presented. It is shown that the short-term modulations of galactic cosmic rays (GCR) are well described by correlating the so lar modulation parameter, , with Earth-based neutron monitor counts using a 85-day time lag and the NASA Models - HZETRN (High Z and Energy Transport) and QMSFRG (Quantum Multiple Scattering theory of nuclear Fragmentation). The dose rates observed by the MARIE instrument are within 10% of the model calculations

Isotopic Dependence of GCR Fluence behind Shielding

In this paper we consider the effects of the isotopic composition of the primary galactic cosmic rays (GCR), nuclear fragmentation cross-sections, and isotopic-grid on the solution to transport models used for shielding studies. Satellite measurements are used to describe the isotopic composition of the GCR. For the nuclear interaction data-base and transport solution, we use the quantum multiple-scattering theory of nuclear fragmentation (QMSFRG) and high-charge and energy (HZETRN) transport code, respectively. The QMSFRG model is shown to accurately describe existing fragmentation data including proper description of the odd-even effects as function of the iso-spin dependence on the projectile nucleus. The principle finding of this study is that large errors (+/-100%) will occur in the mass-fluence spectra when comparing transport models that use a complete isotopic-grid (approx.170 ions) to ones that use a reduced isotopic-grid, for example the 59 ion-grid used in the HZETRN code in the past, however less significant errors (<+/-20%) occur in the elemental-fluence spectra. Because a complete isotopic-grid is readily handled on small computer workstations and is needed for several applications studying GCR propagation and scattering, it is recommended that they be used for future GCR studies

IMECE2008-66292 EXPERIMENTAL ANALYSIS OF VIBRATION OF MICROMACHINED RESONATORS

ABSTRACT Among many different mechanisms that are used for excitation and detection of vibration of micro-beam resonators, electrostatic comb-drives have the benefit of simplicity and large range of linear operation. The disadvantage of using comb-drives is the effect of added mass to the beam; however, the analytical model of the beam-mass system predicts that this shortcoming can be overcome by proper adjustment of the mass, rotary inertia, and location of the comb-drive. In addition, the analytical model can predict the effect of the axial force of the beam on the resonance frequencies. In this paper, the results of the experiments on two resonators are presented. These results are used to verify the validity of the analytical model and finding its parameters. Very close agreement between the theory and experiment is observed. The residual stress of the MEMS structural layer is measured using the calibrated analytical model parameters

Mitochondrial Calcium Uniporter (MCU) defciency reveals an alternate path for ­Ca2+ uptake in photoreceptor mitochondria

Rods and cones use intracellular Ca2+ to regulate many functions, including phototransduction and neurotransmission. The Mitochondrial Calcium Uniporter (MCU) complex is thought to be the primary pathway for Ca2+ entry into mitochondria in eukaryotes. We investigate the hypothesis that mitochondrial Ca2+ uptake via MCU influences phototransduction and energy metabolism in photoreceptors using a mcu-/- zebrafish and a rod photoreceptor-specific Mcu-/- mouse. Using genetically encoded Ca2+ sensors to directly examine Ca2+ uptake in zebrafish cone mitochondria, we found that loss of MCU reduces but does not eliminate mitochondrial Ca2+ uptake. Loss of MCU does not lead to photoreceptor degeneration, mildly affects mitochondrial metabolism, and does not alter physiological responses to light, even in the absence of the Na+/Ca2+, K+ exchanger. Our results reveal that MCU is dispensable for vertebrate photoreceptor function, consistent with its low expression and the presence of an alternative pathway for Ca2+ uptake into photoreceptor mitochondria

Growth of Indonesian infants compared with World Health Organization growth standards

OBJECTIVE: The ability of the World Health Organization (WHO) growth standards to represent the growth of South East Asian infants has been questioned. The aim of this study was to provide contemporary data on the growth of Indonesian breast-fed and formula-fed infants, compared with the WHO growth standards. METHODS: A prospective cohort study of 160 normal healthy infants was undertaken in a suburban area of South Jakarta, Indonesia. Infants from 2-6 weeks of age were recruited, and consumed exclusively either breast milk or infant formula for at least 6 months, with follow-up until 12 months of age. RESULTS: Overall, the infants in this study were lighter (weight-for-age), were shorter (length-for-age) and had smaller head circumferences (head circumference-for-age) than the average WHO Growth Reference Study (WGRS) population but were of similar proportion (weight-for-length). Compared with the WGRS, the z-scores for weight-for-age, length-for-age and head circumference-for-age in the Indonesian children fell from birth to 6 weeks of age and then increased until 3 months of age in both the breast-fed infants and the formula-fed infants. At 6 weeks of age, the weight-for-age z-scores fell below -2 standard deviations (SD) for 16 (20.5%) breast-fed and 40 (51.3%) formula-fed infants, and the length-for-age z-scores fell below -2 SD for 31 (39.7%) breast-fed and 41 (52.6%) formula-fed infants. CONCLUSIONS: The WHO growth standards do not reflect the growth of this cohort of Indonesian infants and may overestimate the levels of underweight and stunted children.
