Abstract Developing Asia experienced a sharp surge in foreign currency reserves
prior to the 2008-9 crisis. The global crisis has been associated with
an unprecedented rise of swap agreements between central banks of
larger economies and their counterparts in smaller economies. We
explore whether such swap lines can reduce the need for reserve
accumulation. The evidence suggests that there is only a limited scope
for swaps to substitute for reserves. The selectivity of the swap lines
indicates that only countries with significant trade and financial
linkages can expect access to such ad hoc arrangements, on a case by
case basis. Moral hazard concerns suggest that the applicability of
these arrangements will remain limited. However, deepening swap
agreements and regional reserve pooling arrangements may weaken the
precautionary motive for reserve accumulation. (C) 2010 Elsevier Inc.

Abstract 2-Acetyl-1-pyrroline (2AP), the volatile compound that provides the
‘popcorn-like’ aroma in a large variety of cereal and food products, is
widely found in nature. Deficiency in amino aldehyde dehydrogenase
(AMADH) was previously shown to be the likely cause of 2AP biosynthesis
in rice (Oryza sativa L.). In this study, the validity of this
mechanism was investigated in soybeans (Glycine max L.). An assay of
AMADH activity in soybeans revealed that the aromatic soybean, which
contains 2AP, also lacked AMADH enzyme activity. Two genes, GmAMADH1
and GmAMADH2, which are homologous to the rice Os2AP gene that encodes
AMADH, were characterized. The transcription level of GmAMADH2 was
lower in aromatic varieties than in nonaromatic varieties, whereas the
expression of GmAMADH1 did not differ. A double nucleotide (TT)
deletion was found in exon 10 of GmAMADH2 in all aromatic varieties.
This variation caused a frame-shift mutation and a premature stop
codon. Suppression of GmAMADH2 by introduction of a GmAMADH2-RNAi
construct into the calli of the two nonaromatic wild-type varieties
inhibited the synthesis of AMADH and induced the biosynthesis of 2AP.
These results suggest that deficiency in the GmAMADH2 product, AMADH,
plays a similar role in soybean as in rice, which is to promote 2AP
biosynthesis. This phenomenon might be a conserved mechanism among
plant species.

Abstract The many advances in the field of landscape ecology allow the analysis
of landscape structure vis-a-vis ecological processes. The study was
conducted to measure patch richness (PR) and shape complexity (i.e.
perimeter-to-area ratio, PAR) of the various patch classes in Central
Cebu Protected Landscape (CCPL). CCPL is an important biodiversity zone
in the Central Visayas region due to its high endemicity. Both patch
richness and shape complexity indices were measured, and their
implications on the management of the landscape were identified. CCPL
consists of four patch classes, namely: perennial crops, annual crops,
forests and built-up areas. Though annual crops showed the highest size
in all patch types, the perennial crops have the highest patch number.
PAR and PR values of forest patches indicate forest ecosystems in the
landscape are highly fragmented and have greater edge than core area.
If conservation objective is to protect endangered species from
extinction, landscape management should focus on the establishment of
connections among isolated forest patches. In particular, management
should consider establishing patches with maximum core area if
conservation is for the protection of core-dependent species.

Abstract Monthly water samplings for algae for one year were conducted from
brackish (BW) and freshwater (FW) fishponds in Bulacan, Bulacan and
Munoz, Nueva Ecija, in Central Luzon, Philippines, respectively. A
total of 58 species of flagellated algae (in their vegetative state)
were identified belonging to five divisions, six classes and 18 genera.
Thirty two new records and one new variety, Trachelomonas volvocina
Ehrenberg var. collaris Boonmee, var nov. (Euglenophyta) are described
in this paper. All the 42 species of euglenophytes were observed in the
freshwater fishponds only while of the 10 species of chlorophytes,
three species were found in BW ponds, five in FW ponds and two species
in both types of pond. Diagnostic descriptions, illustrations,
photographs and habitat records are given for each species or variety.
A key is presented for the species in each division or genus.

Abstract Stock traders consider several factors or objectives in making
decisions. Moreover, they differ in the importance they attach to each
of these objectives. This requires a tool that can provide an optimal
tradeoff among different objectives, a problem aptly solved by a
multi-objective optimization (MOO) system.
This paper aims to investigate the application of multi-objective
optimization to end-of-day historical stock trading. We present a stock
trading system that uses multi-objective particle swarm optimization
(MOPSO) of financial technical indicators. Using end-of-day market
data, the system optimizes the weights of several technical indicators
over two objective functions, namely, percent profit and Sharpe ratio.
The performance of the system was compared to the performance of the
technical indicators, the performance of the market, and the
performance of another stock trading system which was optimized with
the NSGA-II algorithm, a genetic algorithm-based MOO method. The
results show that the system performed well on both training and
out-of-sample data. In terms of percent profit, the system outperformed
most, if not all, of the indicators under study, and, in some
instances, it even outperformed the market itself. In terms of Sharpe
ratio, the system consistently performed significantly better than all
the technical indicators. The proposed MOPSO system also performed far
better than the system optimized by NSGA-II.
The proposed system provided a diversity of solutions for the two
objective functions and is found to be robust and fast. These results
show the potential of the system as a tool for making stock trading
decisions. (C) 2010 Elsevier B.V. All rights reserved.

Abstract There is always the need to regularly monitor fitness status not only
of athletes but of non-athletes as well. This paper is to address this
necessity in order to minimize occurrences of common cardio-respiratory
ailments plaguing through these years, hence enhancing and sustaining a
healthy population.
A total of 510 male and female respondents were included in the 3-year
study of assessing the health status of physical education students at
the University of the Philippines Los Banos, College, Laguna. Analyzing
relationship of anthropometric measures (body mass index and waist-hip
ratio) with some performance indices/musculoskeletal fitness (such as
curl up, push up and sit and reach) through regular physical fitness
test were also done.
Generally, students believe and accept the fact that there are
countless benefits derived from doing a regular exercise and living a
healthy lifestyle. The main problem though is the availability of the
program that would suit to their lifestyle and busy schedules. It is
always the duty of the university, the college and the department to
organize programs that could address individual needs.

Abstract Evaluation for possible embryoprotective/antiteratogenic role using the
hexane fraction obtained from the leaves of Parameria laevigata (A.
Juss.) Moldenke was performed on pregnant ICR mice (Mus musculus L.).
The overall effect of the treatment with P laevigata hexane fraction on
maternal reproductive performance was manifested by the significant
differences observed (p <= 0.05) on the number of live and dead fetuses
per litter between the groups. The incidence of live fetuses was high
and the frequency of dead fetuses per litter was low in all the groups
that received the plant extract including the group that was exposed to
Vitamin A while more dead fetuses/litter (2 +/- 0.71)and less live
fetuses/litter (8.8 +/- 1.1) were seen from the group exposed to
vitamin A only. Morphological analysis of the live fetuses revealed
normal appearance in all the groups except samples exposed to the
teratogen. There was a significant difference in terms of mean fetal
weight and morphological abnormalities per litter between the groups.
The lowest mean fetal weight per litter was obtained from the group
administered with plain vitamin A (0.55 +/- 0.14) and the highest value
was recorded from mice exposed to 50 mg of P laevigata plain (0.92 +/-
0.2) or adjunct to vitamin A (1.02 +/- 0.12). Bone maturation was
greatly reduced by vitamin A administration. Regions significantly
affected include the long bones in the forelimbs and hind limbs. The
degree of ossification was enhanced by treatment with P laevigata
hexane fraction and the effect of the teratogen in reducing bone
mineralization was counteracted in the treated samples given with the
medium and high doses of the plant extract.

Abstract The sensitivities of Betis [Madhuca betis (Blanco) Mac Bride], Antipolo
[Artocarpus. blancoi (Elmer) Merr.] and Kalantas (Toona calantas Merr.
& Rolfe) whose seeds were sown and maintained in two soil types,
namely: Makiling and Pansol soils were established by examining their
responses to four pH levels of simulated rain in terms of seed
germination and early growth of their seedlings. Germination value and
root length were not significantly affected by acidity treatment.
However, height and diameter growth, sturdiness quotient, shoot, root
biomass and shoot- root ratio were found significantly affected by
rainfall acidity. These parameters were then considered as most useful
indicators of sensitivity to acid treatment in the study area. Root
length was affected by acidity treatment and soil type and regarded as
less useful parameter in the study of the sensitivity of plants to acid
treatment. Of the three species studied, 7: calantas was observed to be
the most sensitive to changes in the acidity treatment levels. The
measurements obtained in all seedling growth parameters which were
round to be significantly different showed more remarkable changes in
the said species. With U. betis, the differences in the seedling
responses to the various pH levels of simulated acid rain were found to
be insignificant. Artocarpus blancoi was intermediate between T.
calantas and M. betis.

Abstract The diversity, relative abundance and spatial distribution of macro
land snails (>5mm) were determined in the Mount Makiling Forest
Reserve, Luzon Island, Philippines. Four slopes
(northeast-UPLB-Forestry, southeast-MakBan, northwest-Puting Lupa and
southwest-Sipit) were selected and divided into three elevation
gradients: upper (>600 mast), middle (500-600 masl) and lower (<500
mast) wherein 36 20 x 20 m(2) quadrats were randomly set. Altitude,
temperature, top soil pH, exchangeable calcium, forest type, canopy
cover, number and diameter of trees, and leaf litter depth were
determined or measured. A total of 639 individuals belonging to five
families (Achatinidae, Bradybaenidae, Camaenidae, Cyclophoridae and
Helicarionidae) and 14 species were identified. Of the four slopes,
Puting Lupa had the most number of individuals (299) and species (11)
while MakBan had the least (48 and 3). The most common species was
Ryssota otaheitana (41.47%) while Cochloslyla camelopardalis was the
rarest (0.16%). Canonical correspondence analysis (CCA) showed
significant direct correlation between species and the primary and
mid-montane forests, except for Achatina fulica which was more
associated with mahogany plantations and former slash and burn sites.
The dominant limiting variables for land snail composition were
altitude, temperature, canopy cover and exchangeable calcium. The
present research suggests that endemic macro land snails are more
abundant and diverse in intact and undisturbed forests, and the strong
association of helicostylids to native forest could qualify the group
as potential indicators of healthy forest ecosystems.

Abstract A new class of dynamical maps arises from tandems consisting of an
analog-to-digital converter and a digital-to-analog converter when the
latter’s output is looped back to the formers input. Its nonlinear
function is created when at least one of the lines between the
converters is cut and that which connects to the DAC is tied to a
logical High. Other maps are produced when additional DAC input lines
are similarly altered, or instead clamped to a logical Low. The
resulting closed-loop systems exhibit several bifurcations including
that which lead to pseudo-randomness. Simulation results from numerical
analysis match fairly well with those derived from an electronic
circuit realization. (C) 2010 Elsevier B.V. All rights reserved.

Abstract The Visayan leopard cat (Prionailurus bengalensis rabori) is a small
wild felid of the Negros-Panay faunal region of the Philippines. In
Negros Occidental, many individuals wander into sugarcane fields and
game fowl farms due to the declining forests, causing locals to believe
that leopard cats eat sugarcane or prey on chicks. This study was
conducted to determine the actual feeding habits of Visayan leopard
cats through scat analysis. The cuticular and medullary patterns of
hair from 25 scats collected from May to October 2009 were analyzed to
identify prey species. Results suggest that there are no defined areas
where leopard cat scats and scats from other animals are found. The
first scats were collected in July, increasing until October while none
was collected in May and June. Results suggest that the presence of
Visayan leopard cats in sugarcane fields is influenced by the growth of
sugarcane which attracts rodents. The main prey species consumed by
Visayan leopard cats were Mus musculus (96%), Rattus exulans (96%),
Rattus argentiventer (64%) and Rattus tanezumi (32%) concurring with
many studies that small mammals are the main prey items of leopard
cats. Also, results showed that Visayan leopard cats do not eat birds
or plant matter exclusively, contrary to local belief.

Abstract Soybean protein was reported to lower cholesterol. However, these
proteins tend to have bitter taste. Debittering or removing the taste
of soybean may be done to improve the taste of soybean.
This study was conducted to investigate the effect of feeding
debittered undigested fraction of soybean in young and adult Brown
Norway rats. Eighteen 4- and 32-week old male Brown Norway rats were
fed for 22 days with 3 types of protein sources: casein (CAS), soybean
(SOY) and debittered undigested fraction of soybean (UDF). The rats
were divided into 3 groups with 6 rats per group. Debittered UDF from
soybean isolate did not exert any aggravating effect on the age-related
change in lipid metabolism. Both serum and liver cholesterol levels
were decreased when UDF was fed in both age groups. Adult rats showed
to have a comparable desaturation index while debittered UDF-fed young
rats demonstrated the lowest desaturation index. Debittered UDF might
not be efficient in increasing the desaturation of linoleic acid to
arachidonic acid.

Abstract Rice spikelet rot disease (SRD) is an emerging disease of rice panicle
in China which affects both rice yield and grain quality Four fungal
pathogens were isolated from diseased rice grains Morphological
observation biological testing and molecular characterization led to
identify these fungi as Fusarium proliferatum Bipolaris australiensis
Curvularia lunata and Alternaria tenuis The four fungi can grow from 10
degrees C to 40 degrees C and from pH 5 to pH 10 The most suitable
temperature range is 25 degrees C-30 degrees C however the optimal pH
for sporulation of these fungi varies greatly The four fungi can grow
on media supplemented with different carbon and nitrogen sources These
differences in carbon and nitrogen requirements suggest differences in
trophism and have large effects on hyphal growth and spore production
The results suggest that rice SRD is caused by various fungi with
diverse physiological characteristics (C) 2010 Elsevier Ltd All rights

Abstract In recent years a rice panicle disease-rice spikelet rot occurred
seriously in large rice-growing area in China, causing the rice grains
discolor, unfilled and deform It does not only influence the rice yield
because of the colored pathogens and toxigenic but also changes the
appearance of the rice and reduces its quality Spikelet rot disease
influences on the rice production and market price, and causes harm to
the safety and health of human and livestock This paper makes effort to
elucidate the occurrence epidemic regularity of the disease the
pathogenicity of isolates Fungicides to control the disease were
preliminarily selected in lab and control efficiency test were
conducted in field The investigation results indicate that japonica
varieties and their hybrid combination tighten panicle varieties are
easier to be infected by the disease than that of the indica rice
varieties with loosen panicles It was propitious to the disease
occurrence and epidemic when rice late booting to flowering period met
the overcast rainy (high humidity) and warm (25-33 degrees C) climate
Indoor selection results showed that ketotriazole shows very good

Abstract The objective of this study was to evaluate the efficacy and
tolerability of extended release quetiapine fumarate (quetiapine XR) as
maintenance monotherapy for patients with generalized anxiety disorder
(GAD). Time-to-event (anxiety symptom recurrence; maximum 52 weeks)
multicenter, randomized-withdrawal, parallel-group, double-blind,
placebo-controlled study of quetiapine XR (50-300 mg/day) following
open-label run-in (4-8 weeks) and open-label stabilization (>= 12
weeks). Primary variable: time from randomization to anxiety event.
Secondary variables included: Hamilton Anxiety Rating Scale (HAM-A)
total, HAM-A psychic/somatic anxiety factors, Clinical Global
Impression-Severity of Illness (CGI-S), and Quality of Life, Enjoyment
and Satisfaction Questionnaire (Q-LES-Q) scores; adverse events (AE)
reporting. Four hundred and thirty-two patients, stabilized on
quetiapine XR, were randomized to continue quetiapine XR (N=216) or
switch to placebo (N=216). Risk of anxiety symptom recurrence was
significantly reduced by 81% for quetiapine XR versus placebo: hazard
ratio = 0.19 (95% confidence interval 0.12-0.31; P < 0.001). Fewer
patients receiving quetiapine XR (N=22, 10.2%) than placebo (N=84,
38.9%) experienced anxiety symptom recurrence. Significant differences
were observed between quetiapine XR and placebo in: HAM-A total,
psychic/somatic, CGI-S (all P < 0.001) and Q-LES-Q (P < 0.05) scores.
AEs (>10%) during open-label treatment were dry mouth, sedation,
somnolence, dizziness, fatigue, and constipation. During randomized
treatment, the most common AEs for quetiapine XR were headache and
nasopharyngitis. Quetiapine XR monotherapy reduced the risk of anxiety
symptom recurrence in patients with GAD stabilized on quetiapine XR,
with tolerability results consistent with the known profile of
quetiapine. Int Clin Psychopharmacol 26: 11-24 (C) 2010 Wolters Kluwer

Abstract We demonstrate an accurate procedure based on linear discriminant
analysis that allows automatic authorship classification of opinion
column articles. First, we extract the following stylometric features
of 157 column articles from four authors: statistics on high frequency
words, number of words per sentence, and number of sentences per
paragraph. Then, by systematically ranking these features based on an
effect size criterion, we show that we can achieve an average
classification accuracy of 93% for the test set. In comparison,
frequency size based ranking has an average accuracy of 80%. The
highest possible average classification accuracy of our data merely
relying on chance is similar to 31%. By carrying out sensitivity
analysis, we show that the effect size criterion is superior than
frequency ranking because there exist low frequency words that
significantly contribute to successful author discrimination.
Consistent results are seen when the procedure is applied in
classifying the undisputed Federalist papers of Alexander Hamilton and
James Madison. To the best of our knowledge, the work is the first
attempt in classifying opinion column articles, that by virtue of being
shorter in length (as compared to novels or short stories), are more
prone to over-fitting issues. The near perfect classification for the
longer papers supports this claim. Our results provide an important
insight on authorship attribution that has been overlooked in previous
studies: that ranking discriminant variables based on word frequency
counts is not necessarily an optimal procedure. (C) 2010 Elsevier B.V.

validated mostly with adult (teacher and university student) samples.
The present study examines the content and structure of values of
middle adolescents in Singapore, the Philippines, Indonesia, and
Australia. The 40-item version of the Portrait Values Questionnaire was
administered to 230 adolescents in each country (total N = 920; boys
and girls were equal) and smallest space analysis was performed.
Consistent with theory, the 10 first-order values and the four
second-order values, organized in two bipolar dimensions, were
identified in all samples. In support of the developmentally modified
value model for young people, there was some evidence for the periphery
of power to achievement. Interestingly, the location of benevolence and
universalism were reversed across all cultural groups, and tradition
values separated into self-restriction and faith. Overall, the findings
support the claim that Schwartz’s theory of values is neither
restricted to adults nor solely based on a particular instrument and is
generalizable across diverse national contexts.

Abstract There are intensive studies on the issues of environment practice and
business innovation capability, have been dealt with extensively from
practitioners and academicians, however, studies on the evaluation of
green business innovation capabilities (GBICs) are few. This study
tackles the evaluation assessment using fuzzy set theory, analytical
network process and importance-performance analysis. Specifically, this
study is using the theoretical framework of GBICs and proposed hybrid
approach, which are new in the theoretical and empirical literatures.
An expert group was empirical assessment to the perception on PWB
sector and a manufacturing firm is evaluated. The analytical results
indicated that this proposed hybrid method is a suitable and effective
method for identifying and analyzing the strategic competitiveness of
GBICs at case firm, especially when evaluation criteria are dependent
in uncertainty. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract The health and functioning of coral reef ecosystems worldwide is in
decline, and in the face of increasing anthropogenic stress, the rate
of decline of these important ecosystems is set to accelerate.
Mitigation strategies at regional scales are costly, but nevertheless
critical, as reef systems are highly connected across regions by ocean
transport of both larval propagules and pollutants, It is essential
that these strategies are informed by sound science, but the inherent
complexity of coral reef systems confers significant challenges for
scientists and managers. Models are useful tools for dealing with
complexity and can inform decision making for coral reef management.
We develop a spatially explicit biophysical model for a general coral
reef system. The model couples dynamics from local (10(2) m) to
regional (10(6) m) scales, and explicitly incorporates larval
connectivity patterns derived from sophisticated larval dispersal
models. Here, we instantiate and validate the model for coral reefs in
the Philippines region of the South China Sea. We demonstrate how the
model can be used in decision support for coral reef management by
presenting two examples of regional-scale scenario projection relating
to key management issues in the Philippines: (i) marine reserve design
and the recovery of fish stocks; and (ii) synergistic effects between
coral bleaching and poor water quality. These scenarios highlight the
importance of considering multiple stressors to reef health and
patterns of larval connectivity in regional-scale management decisions.

Abstract IR 72 rice variety (high-amylose type) was combined with IPB Var. 6, a
Quality Protein Maize (QPM) white corn, obtaining a total of nine
different rice-corn composites (rice and corn combination). QPM
contains nearly twice as much usable protein that is specifically rich
in lysine and tryptophan, the two limiting essential amino acids in
rice. Addition of QPM white corn grits to IR 72 rice variety increased
the amount of protein, lysine, tryptophan, fat, ash, starch, amylose
and total fiber content of the rice-corn composites. Gel consistency
and hardness were relatively higher in samples having more corn. Both
IR 72 rice variety and QPM white corn have the same gelatinization
temperature below 70 C. Generally, based on a 7-point Hedonic rating
scale for evaluation, all the rice-corn composites were considered
acceptable in terms of color, odor, flavor, cohesiveness and texture.
There was a significant difference in each sensory attribute except
cohesiveness. The sensory evaluation showed that the 70:30 (rice:corn)
ratio had the highest preference score in terms of flavor and general
acceptability. The study showed that combining IR 72 rice variety and
QPM white corn grits at a 70:30 ratio can be utilized as a staple food
owing to its improved nutritional and sensory qualities and thus, can
be used to ameliorate food insecurity in the Filipino families and

Abstract To examine the anti-angiogenic property of garlic (Allium sativum L.)
oil, the blood vessel formation and branching complexity in the
chorioallantoic membranes (CAMs) of avian embryos were measured
quantitatively by histologic microvessel point counting and macroscopic
fractal dimension analysis. Surgical gelfoams, as matrix for the
growing blood vessels, were implanted onto the CAMs. Seventy three-day
old fertilized whiteleghorn eggs were divided into negative control
(NC), which received neither phosphate buffered saline (PBS) norgarlic
oil, three positive control (PC) which received 20, 50 and 100 mu l PBS
and three treatment groups (TG) which received 20, 50 and 100 mu l
garlic oil. The study lasted for 13 days during which samples were kept
in constant 37 degrees C. On the last day, the gelfoam implants with
the surrounding CAMs were detached from the embryos and processed for
light microscopy. A second batch of duck fertilized eggs was run in
similar conditions. The CAMs were removed on the last day, mounted on
water-absorbent white boards and photographed with macrolens for the
fractal dimension analysis. Results showed that garlic oil
significantly reduced the number of microvessels per area in the chick
embryo CAMs in a dose-dependent manner, that is, the higher the dose,
the lower the percent microvessel area incurred. A decreasing trend in
blood vessel branching complexity was found in the fractal dimension
analysis but not significantly different from the other groups. While
there is a discrepancy in the results of the two assays, the potential
anti-angiogenic property of garlic oil could not be disregarded.
Possibly, an increase in the sample size could increase the power of
the statistical test and may yield more conclusive results.

Abstract In future climates, rice could more frequently be subjected to
simultaneous high temperature and water stress during sensitive
developmental stages such as flowering. In this study, five rice
genotypes were exposed to high temperature, water stress and combined
high temperature and water stress during flowering to quantify their
response through spikelet fertility. Microscopic analyses revealed
significant differences in anther dehiscence between treatments and
genotypes, with a moderately high association with the number of
germinated pollen grains on the stigma. There was a strong relationship
between spikelet fertility and the number of germinated pollen on
stigmas. Although, all three stress treatments resulted in spikelet
sterility, high-temperature stress caused the highest sterility in all
five genotypes. A cumulative linear decline in spikelet fertility with
increasing duration of independent high-temperature stress and in
combination with water stress was quantified. Better anther dehiscence,
higher in vivo pollen germination, and higher spikelet fertility were
observed in both the N22 accessions compared with IR64, Apo and
Moroberekan under high temperature, water stress and combined stress,
indicating its ability to tolerate multiple abiotic stresses. (C) 2010

Abstract The dynamics of human-forest interaction in Aborlan Guba System,
Aborlan, Palawan was determined by doing social and literature surveys
and by using the STELLA program for model development. The direct users
of the forest were poor Indigenous Peoples and migrants. Income, family
size, education and size of cultivated farm significantly influenced
the harvest frequency of forest products.
Using current data and trends to extrapolate conditions over the next
50 years, the simulation showed that the Aborlan Guba System would
become less and less sustainable in ecological and socioeconomic terms.
The model projected that forest cover declines at 3 ha/year.
The best way to sustainably manage the Aborlan Guba System is by
increasing people’s income, reducing population growth and increasing
reforestation efforts especially for rattan species and almaciga trees.
For immediate protection, the area must be upgraded from a Controlled
Use Zone to Core Zone but declaring it into a Protected Area under
NIPAS law ensures its long term sustainability.

Abstract In this present work, a thermophysical property characterization of
aqueous solution of tris(hydroxymethyl)aminomethane (TRIS), a
biological buffer, was done. The investigated properties were
refractive index (n), density (rho), and electrolytic conductivity
(kappa). These properties were measured for temperatures up to 353.15 K
(at normal atmospheric condition) and for the entire composition range
where TRIS is still soluble in water. The measured properties were
reported as functions of temperature and composition. A modified form
of the Vogel-Tamman-Fulcher equation which leads to an Arrhenius-type
asymptotic exponential function was used to generally correlate the
temperature and compositional dependence of the considered properties
and satisfactory results were obtained. (C) 2010 Elsevier Ltd. All
