| distribution and density of mosquitoes in two endemic areas for bancroftian filariasis in sorsogon, philippines. | mosquito density in rangas where abaca is in abundance is much higher, almost twice, than that of putiao where abaca is absent. the adult density of aedes poecilus over aedes ananae in the two areas combined is 3 to 4 times whereas the larval density of the former is much lower than aedes ananae. the banana axils is a favorite breeding place for aedes poecilus but may also utilize the abaca axils. this finding is very favorable in the transmission of bancroftian filariasis because this species o ... | 1978 | 34889 |
| bancroftian filariasis in a philippine village: entomological findings. | bancroftian filariasis in an isolated philippine village has been intensively investigated; this paper reports the entomological findings. surveys were carried out six months apart in the driest and wettest months. significant transmission was demonstrated only during the wet season. aedes poicillius was the major vector of wuchereria bancrofti. ae. poicilius accounted for 58% of larvae found in the axils of banana plants and 31% of those in abaca axils; negligible numbers of larvae of this spec ... | 1979 | 39349 |
| the effect of modelling on drinking rate. | three male college seniors were asked to drink beer at their normal rate in a simulated tavern setting. each was paired with a confederate, also a male college senior, in an abaca single subject design. in the baseline conditions, the confederate matched the drinking rate of the subject. baseline and all subsequent conditions were continued in 1-hr sessions until a stable drinking rate was achieved. in condition b, the confederate drank either one third more or one third less than the subject's ... | 1977 | 885827 |
| a study of bancroftian filariasis on the islands of batan and rapu rapu, philippines. | the islands of batan and rapu rapu in southeastern luzon, philippines, were surveyed for filariasis from november 1984 to may 1985. microfilariae of bancroftian filariasis were detected in 10.5% of the people over one year of age. microfilarial rates and intensity of infection were the same for males and females. the highest rates for both sexes were in the 56- to 60-year-old age group. aedes poicilius, which breeds in abaca and banana plants, was found to be very anthropophilic, comprising 96.5 ... | 1988 | 2906482 |

| compulsive exhibitionism successfully treated with fluvoxamine: a controlled case study. | paraphilias are psychosexual disorders that are usually conceptualized as deviant in nature. yet in some cases, paraphilia can be conceptualized as an obsessive compulsive disorder. | 1994 | 8071253 |
| the functional morphology of the petioles of the banana, musa textilis. | bananas are among the largest herbs in the world and their lightweight petioles hold up huge leaves. this study examined how the petioles manage to achieve adequate rigidity to do this, while allowing extensive and reversible reconfiguration in high winds. morphological and anatomical examination of the petioles and leaves of musa textilis suggested how these two apparently incompatible abilities are achieved. the hollow u-shaped section of the petiole and the longitudinal strengthening elements ... | 2000 | 11141182 |
| increased effort requirements and risk sensitivity: a comparison of delay and magnitude manipulations. | reward magnitude and delay to reward were independently manipulated in two separate experiments examining risk-sensitive choice in rats. a dual-running wheel apparatus was used and the tangential force resistance required to displace both wheels was low (50g) for half of the subjects, and high (120g) for the remaining subjects. concurrent fi30-s and fi60-s schedules delivered equivalent amounts of food reward per unit time (i.e. 5 and 10 pellets of food, respectively), and these conditions serve ... | 2003 | 12642167 |
| qualitative similarities in cognitive impairment associated with 24 h of sustained wakefulness and a blood alcohol concentration of 0.05%. | previous studies that have quantified fatigue-related cognitive impairment as blood alcohol concentration (bac) equivalents have been limited by two issues: the effect of practice on tests of cognition and, more importantly, the statistic used to quantify change in cognitive performance. the current study addressed these issues by adopting an abaca design, which allowed for the adequate control of practice effects, and by using effect size metrics, which enabled direct comparisons to be made in ... | 2003 | 14633237 |

| chemical composition of abaca (musa textilis) leaf fibers used for manufacturing of high quality paper pulps. | the chemical composition of leaf fibers of abaca (musa textilis), which are commonly used for high-quality paper pulp production, was thoroughly studied. the results revealed that the lignin content was 13.2% of the total fiber. the analysis of abaca fibers by pyrolysis coupled to gas chromatography-mass spectrometry (py-gc/ms) released predominantly compounds arising from lignin and p-hydroxycinnamic acids, with high amounts of 4-vinylphenol. the latter compound was demonstrated to arise from p ... | 2006 | 16787004 |
| phenylphenalenone type compounds from the leaf fibers of abaca (musa textilis). | a series of phenylphenalenone type compounds, known to play a role as phytoalexins in plants of the musaceae family, have been identified for the first time in the leaf fibers of abaca (musa textilis). among the phenylphenalenone type compounds identified, the structure of a novel compound, (1r)-2,3-dihydro-4,9-dihydroxy-8-methoxy-1-phenylphenalene, has also been described in abaca fibers. its structure was elucidated by analysis of one- and two-dimensional nmr (correlation spectroscopy, heteron ... | 2006 | 17090116 |
| abacá bunchy top virus, a new member of the genus babuvirus (family nanoviridae). | two isolates of a novel babuvirus causing "bunchy top" symptoms were characterised, one from abacá (musa textilis) from the philippines and one from banana (musa sp.) from sarawak (malaysia). the name abacá bunchy top virus (abtv) is proposed. both isolates have a genome of six circular dna components, each ca. 1.0-1.1 kb, analogous to those of isolates of banana bunchy top virus (bbtv). however, unlike bbtv, both abtv isolates lack an internal orf in dna-r, and the orf in dna-u3 found in some b ... | 2008 | 17978886 |

| monolignol acylation and lignin structure in some nonwoody plants: a 2d nmr study. | lignins from three nonwoody angiosperms were analyzed by 2d nmr revealing important differences in their molecular structures. the musa textilis milled-wood-lignin (mwl), with a syringyl-to-guaiacyl (s/g) ratio of 9, was strongly acylated (near 85% of side-chains) at the gamma-carbon by both acetates and p-coumarates, as estimated from (1)h-(13)c correlations in c(gamma)-esterified and c(gamma)-oh units. the p-coumarate h(3,5)-c(3,5) correlation signal was completely displaced by acetylation, an ... | 2008 | 18945458 |
| dna analysis of natural fiber rope. | when rope is found at a crime scene, the type of fiber is currently identified through its microscopic characteristics. however, these characteristics may not always unambiguously distinguish some types of rope from others. if rope samples contain cells from the plants of origin, then dna analysis may prove to be a better way to identify the type of rope obtained from a crime scene. the objective of this project was to develop techniques of dna analysis that can be used to differentiate between ... | 2009 | 19018936 |
