Effect of fluid motion on movement performance and finger-force pattern during manipulation of Containers/Cups filled with LiquidRAVALA, KALPANA 06 September 2011 (has links)
The purposes of this study were to: 1) evaluate how movement performance of the thumb and fingers were modified during manipulation of objects with and without fluids and 2) to quantify movement performance and accuracy during manipulation of objects, in two different modes of manipulation, i.e., pendulum and inverted pendulum. Twenty young healthy adults (age 24-35) were recruited and performed two predictable cyclic tracking tasks and episodic short-duration precision movement task. No change in movement performance observed in open-loop or episodic tasks. However, in closed-loop task, mode of manipulation (IP versus P) had a significant effect on amplitude consistency (P<0.001), and temporal accuracy (P<0.050).Fluid motion had a significant effect on RMS of index finger contact forces (p < 0.01) in episodic task. In conclusion, fluid motion had no significant effect on movement performance and accuracy. The quality of movement was better in pendulum mode than inverted pendulum movement.

Response in maternal traits to selection for growth and feed efficiency in swine2014 July 1900 (has links)
The objective of this study was to determine the relationship between the traits of average daily gain, backfat, loin muscle depth, feed intake and feed conversion measured in growing gilts and their subsequent feed intake (as estimated by feed delivery) in lactation, and to estimate the effects of lactation feed intake on subsequent maternal productivity and sow longevity. Phenotypic performance measurements and estimated breeding values (EBV) were compared with first and second parity lactation feed delivery in a group of selected nucleus gilts of 3 genetic lines. The effects of lactation feed delivery on weaning to conception interval, total piglets born in the subsequent litter and lifetime productivity measures were investigated. Genetic parameters for the growing period traits of average daily gain, backfat, loin muscle depth, daily feed intake and feed conversion, as well as maternal productivity traits of litter size (number alive at day 2), weaning to conception interval and litter weaning weight were estimated and EBV were computed.
Phenotypes of growth rate, feed intake, backfat and loin muscle depth recorded in the growing period were not good predictors of lactation feed delivery. However, one genetic line (YO-A) showed significant correlations between second parity lactation feed delivery and growth rate and loin muscle depth measured in the growing period.
EBV calculated for the growing period traits of growth rate, feed intake and feed conversion showed much stronger relationships with lactation feed delivery than the growing period phenotypes, particularly for parity 2. Parity 2 lactation feed delivery showed favorable correlations with EBV for growth rate and feed conversion and an unfavorable correlation with the growing period daily feed intake EBV.
Lactation feed delivery in the first and second parity had significant effects on the odds of occurrence of the next litter, next litter total born, stayability to parity 3 or parity 4 and sow longevity. Since lactation feed intake is very important to subsequent productivity and longevity of sows and has a positive (unfavorable) genetic correlation with growth period feed intake, it is recommended that lactation feed intake be measured directly and included in the selection goal.
The correlation between lactation feed delivery in parity 1 and parity 2 was low at 0.28 across genetic lines, leading to the conclusion that lactation feed delivery in the first and second parities appear to be different traits under different control mechanisms.
It is concluded that a balanced selection program for maternal lines that includes selection for reduced feed intake, feed conversion or residual feed intake measured in the growing period, should also include selection for increased lactation feed intake (probably in combination with changes in sow body weight or backfat during lactation in order to prevent negative consequences for sow longevity or productivity). It is also recommended that lactation feed intake in the first and later parities be evaluated as separate traits.

Intercropping corn and soybean for high-protein silage in a cool temperate regionMartin, Ralph C. January 1990 (has links)
The overall hypothesis of this research was that silage biomass and protein yields would be higher in corn-soybean intercrops than in monocrops on the same land area. Yields, European corn borer infestation and N transfer were tested over tall and dwarf corn hybrids, nodulating and nonnodulating soybean genotypes and at 0, 60 and 120 kg N ha$ sp{-1}$. Land Equivalent Ratios ranged from 0.97 to 1.23, but most were higher than 1.10. Protein concentrations of corn-soybean silage, up to 10.76%, were on average 9.24% vs. 7.41% in corn silage. A general trend of higher protein yield ha$ sp{-1}$ in intercrops compared to corn monocrops was significant in 1986. Corn-soybean intercrops at 60 kg N ha$ sp{-1}$ and three population densities were $132 to $261 ha$ sp{-1}$ more cost effective than monocropped tall corn at 120 kg N ha$ sp{-1}$. European corn borer infestation was reduced by intercropping and was higher at 120 kg N ha$ sp{-1}$ than at 60 or 0 kg N ha$ sp{-1}$. Under normal rainfall, dwarf corn had higher protein and yield levels when intercropped with nodulating rather than nonnodulating soybean. On N-depleted soil, N transfer was detected from nodulating soybean to nonnodulating soybean and to corn by the $ sp{15}$N dilution method, and to corn by direct $ sp{15}$N labelling of nodulating soybean.

Total fatty acid composition of autoxidized anchovy meal and studies of related model systemsRoehm, Jeffrey Noyes 08 October 1965 (has links)
The variation in fatty acid composition between the "bound" and
"free" lipid in stored anchovy meal was determined using gas-liquid
chromatographic analysis. A model system of fresh anchovy oil on
powdered lactalbumin was also studied to determine the changes in
extractability and fatty acid composition which occur during oxidation.
All of the lipid-protein systems examined were first extracted
with hexane. The extracted protein was then extracted with choroform::
methanol (2:1 v/v), and finally digested in HCl and the hydrolysate
extracted with diethyl ether. The chloroform : methanol extract
and HCl digestion represented oil which was bound to the
protein.
Each lipid extract was interesterified with methanol to yield
the corresponding methyl esters, and these esters were then analyzed by gas-liquid chromatography. Both quantitative and qualitative
analysis was carried out using a diethylene glycol succinate
packed column in a gas chromatograph equipped with a hydrogen
flame detector.
The results of these investigations showed that the oil from
anchovy meal differed markedly in fatty acid composition from the
corresponding fresh oil. Although the types of fatty acids found were
identical to those in the fresh oil, there was considerable quantitative
variation. These differences were characterized by smaller
amounts of polyunsaturated fatty acids in the meal, and correspondingly
larger amounts of saturated and monoenoic fatty acids. The
greatest change occurred in the acid, 20:5.
Anchovy meal contained a "bound" lipid fraction which varied
in quantitative fatty acid composition with the readily extractable
lipid. The fractions associated with the protein had higher proportions
of 22:4, 22:5, and 22:6, with the acid digest fraction considerably
lower in the monoenoic fatty acids.
The oxidation of anchovy oil and anchovy oil methyl esters on
lactalbumin produced a reduction in hexane extractable lipid with a
corresponding increase in lipid which was soluble only in chloroform
: methanol or after HCl hydrolysis. These changes were more
drastic when untreated anchovy oil was used. The oxidation of
anchovy oil methyl esters on lactalbumin produced a reduction in the amounts of polyunsaturated fatty acids present in the hexane extract.
The other solvent extractions, however, yielded only higher
molecular weight compounds which could not be analyzed by GLC.
These observations led to the conclusion that the fatty acids formed
compounds which interacted before being bound to the protein. / Graduation date: 1966
