Interaction between Internal Shear Reinforcement and External FRP Systems of RC Beams: Experimental Study
Authors: Teo Wee , Hing Kilian Lau Meow , Liew Mohd Shahir
Published: February 2017

Extensive research effort has been conducted on the shear strengthening of reinforced concrete (RC) beams with externally bonded FRP systems. However, there are still few aspects on their behaviour that are yet to be fully understood. One of them is the effect of shear interaction between internal transverse shear reinforcement and the external FRP systems. This paper is intended to study experimentally the interaction between these two shear reinforcement components. To do so, a total of five concrete beams were assembled in this investigation. All beams were properly instrumented in order to obtain as much data as possible. Four beams were externally strengthened with FRP with different strengthening and wrapping schemes. Their influence and interaction with the internal transverse stirrups in shear resistance were discussed based on the modes of failure exhibited, deflection and strain (steel and FRP) responses. Overall the results obtained are in good agreement with many researches which indicated that addition of externally bonded FRP, as a matter of fact, preserves the integrity of internal transverse stirrups. With continuous FRP sheets and U-wrapped scheme, greater FRP contribution to the shear resistance can be expected.

Published: February 2017

A circulating fluidized bed (CFB) boiler generates energy by burning petroleum coke. Because burnt petroleum coke has a high sulfur content, limestone is added to the boiler to reduce the emittance of sulfur dioxide through desulfuration. The residue collected from the boiler is called CFB ash. CFB boilers in Taiwan can produce 328,000 tonnes of CFB fly ash per year. In this study, the pozzolanic characteristics of CFB fly ash were investigated by blending CFB fly ash and ordinary Portland cement (OPC). The CFB fly ash was mainly composed of CaO, SO3, and SiO2 in concentrations of 37.8%, 9.2%, and 2.2%, respectively. The crystals of CFB fly ash contained 3CaO.SiO2, 2CaO.SiO2, Ca(OH)2, C-S-H (Tobermolite), and Ettringite. The results revealed that applying the toxicity characteristic leaching procedure to CFB fly ash renders it suitable for use in blended cement. At later curing ages (90 days), the pore volumes of both the OPC and the CFB-fly-ash-blended cement pastes (CFBFABCP) decreased as the curing time increased. A possible explanation is that C3S and C2S were consumed to form C-S-H gel, resulting in an increase in the Q1 and Q2 groups identified by 29Si Nuclear Magnetic Resonance (NMR) spectroscopy. Furthermore, the peak of the Q0 group decreased, but those of the Q1 and Q2 peaks increased with an increasing curing time. The pozzolanic activity of the CFBFABCP containing 10% CFB fly ash indicates that it is a suitable substitute for OPC in blended cement.

Authors: Aisiah Aisiah , Suhartono Suhartono , Sumarno Sumarno
Published: February 2017

The study aimed to develop a measurement model of historical awareness through a research and development model adopted from the Plomp model. Historical awareness was measured through four components, namely: knowledge of historical events, understanding of historical research method, meaning of historical events, and usefulness of history. The development procedures of the development model included a preliminary investigation in the form of literary study about the constructs of historical awareness. In the design stage, the researcher designed a conceptual model and a hypothetical measurement model about historical awareness. Then, the researcher performed a test construction namely assembling the test instrument for measuring historical awareness. Eventually, the researcher administered a test, did evaluation and made revision. The test in the study referred to the empirical testing of the instrument, while the evaluation in the study referred to the efforts to identify the obstacles that the participants encountered within the empirical testing of the instrument in order to revise it. The empirical testing of the instrument involved history teacher-candidates at Universitas Negeri Yogyakarta and Universitas Negeri Padang. The data were gathered through the test by using the measurement instrument in the form of associative multiple choice test. For the construct analysis, the researcher implemented confirmatory factor analysis by means of Lisrel 8.80 program. The results of the analysis show that the χ2 = 121.98, the p-value = 0.11, RMSEA = 0.043. In other words, the measurement model of historical awareness that had been developed was supported by the empirical data.

Published: February 2017

A field experiment was conducted to investigate the impact of phosphorus (30, 45 and 60 kg P ha-1) and organic matter (canola straw, berseem straw and farmyard manure) on growth and fodder yield of moth bean (Vigna aconitifolia Jacq.) under irrigated and dryland conditions. The experiment was conducted under two field conditions viz. (i) with irrigation and (ii) without irrigation (dryland). The experiment under each field condition was laid out in a randomized complete block design having three replications. The results revealed that P and organic matter treated plots (rest) under both irrigated and dryland conditions had better growth and produced higher fresh and dry fodder yields over control (no P and no organic matter applied). Moth bean planted under irrigated condition (no moisture stress) had improved growth, and produced higher fresh and dry fodder yields over dryland condition. Increasing the rate of P increased growth, fresh and dry fodder yields (60 kg P ha-1 > 45 kg P ha-1 > 30 kg P ha-1). Increase in growth, fresh and dry yields was obtained with the application of farmyard manure over plant residues incorporation. We concluded from this study that application of P at the highest rate of 60 kg P ha-1 along with farmyard manure (5 t ha-1) as source of OM improve growth and fodder yield of moth bean under irrigated and dryland conditions under semiarid climates.

Published: February 2017

An experiment was conducted to measure the variability in urea-N and potassium concentration with injection time at different operating pressures. It was done with urea and muriate of potash (MOP) for different amounts of fertilizers (10, 16 and 21 kg of urea and 5, 7.5 and 10 kg of MOP) at different operating pressures (1.5, 2.0, 2.5 and 3.0 kg cm-2).Polynomial and exponential forms of empirical equations were developed to determine the concentration of fertilizer in the tank with injection time. In the first half an hour the remaining concentrations of both the fertilizers of different amounts in fertigation tank was less than 40% and in the next one hour the remaining concentration was less than 10%. There was no significant effect of operating pressure on change in fertilizer concentration with injection time. However, higher operating pressure may be used to apply the maximum amount of fertilizer in the beginning of the injection duration. The exponential form of equation is easier in use and also accurate for relating the concentration of fertilizers in fertigation tank with injection time. The constants of exponential equation obtained for different operating conditions can be used by the designers of pressurized irrigation system for economical and accurate use of pressure difference method of injecting fertilizers.

Published: February 2017

Physical properties of commonly grown Sri Lanka groundnuts cultivars and promising accession varied considerably and numbers of kernels, pod beak, reticulation, testa colour, and shell out percentage have differences among groundnuts. However, they showed more similarities for most of the characters. Moisture (5.4-8.4%), crude protein (18.7-28.5%), lipid (43.4-53.0%), ash (4.4-5.8%), carbohydrates (9.3-18.2%) and energy level (565.7-618.2kcal) contents varied considerably. Quality and flavor of edible groundnuts and its products are affected by fatty acid composition of oil. Lipids were mainly composed of mono and polyunsaturated fatty acids (>78% of the total lipids). Fatty acid composition analysis indicated that oleic acid (C18:1) was the main constituent of monounsaturated lipids in all seed samples. With the exception of ANKG1, linoleic acid (C18:2) was the major polyunsaturated fatty acid. The saturated fatty acids (Palmatic, Stearic acid and behenic acid) in different cultivars ranged between 10.2 to 15.6%, 2.5 to 6.3% and 1.1 to 5.3%, respectively. Differences among cultivars for oleic acid exhibited significance which ranged between 38.2 to 47.4%. Similarly, cultivars differed statistically for linoleic acid which showed a range of 23.1 to 38.7%. Oleic to linoleic acid ratio was differed and all the released varieties were below the minimum standard level of 1.6, whereas ICGV 86590 and ICGV 00073 showed higher O/L ratio of 1.94 and 1.75 respectively.

Published: February 2017

While different societies attach different weights and priorities to these objectives, it is largely in the political and economic means adopted for achieving these ends that societies differ. The differences in means are of paramount importance because the ultimate objectives are never fully attained as a consequence of which we forever live in transition. However, it is largely agreed that good governance is a fundamental building block of a just and economically prosperous society. This is as true for public governance as it is for corporate governance.
Kinetic model describing the UV/H2O2 photodegradation of phenol from water
Authors: Rubio-Clemente Ainhoa , Chica Edwin , Peñuela Gustavo
Published: February 2017

A kinetic model for phenol transformation through the UV/H2O2 system was developed and validated. The model includes the pollutant decomposition by direct photolysis and HO?, HO2? and O2 ?- oxidation. HO? scavenging effects of CO3 2-, HCO3 -, SO4 2- and Cl- were also considered, as well as the pH changes as the process proceeds. Additionally, the detrimental action of the organic matter and reaction intermediates in shielding UV and quenching HO? was incorporated. It was observed that the model can accurately predict phenol abatement using different H2O2/phenol mass ratios (495, 228 and 125), obtaining an optimal H2O2/phenol ratio of 125, leading to a phenol removal higher than 95% after 40 min of treatment, where the main oxidation species was HO?. The developed model could be relevant for calculating the optimal level of H2O2 efficiently degrading the pollutant of interest, allowing saving in costs and time.

Single nucleotide polymorphisms (SNPs) in cytokine genes may alter the level
and function of secreted cytokine; therefore, SNPs can influence the immune
response. The aim of the present study was to determine the association of
TNF-? -308G/A single nucleotide polymorphism in tuberculosis patients in the
Azeri population of Iran. The TNF-308G/A single nucleotide polymorphism in
the promoter region was genotyped by using the allele-specific PCR method in
200 healthy controls and 124 tuberculosis patients. The distribution of
allele frequencies for TNF-? -308G/A polymorphism between control and
tuberculosis patient groups was not significant (P-value = 0.058, OR = 1.5).
Furthermore, no statistically significant association was found between TNF-?
-308G/A genotype and resistance/susceptibility to TB (P-value = 0.102). Our
results suggest that TNF-? -308G/A polymorphism has no measurable effect on
the development of tuberculosis in Azeri population of Iran.

Fifteen genotypes of bread wheat (Triticum aestivum L.) and fifteen genotypes
of durum wheat (Triticum durum Desf.) were evaluated in the multi-environment
trial during 2010-11. and 2011-12 vegetation seasons to investigate
components of variance, heritability in a broad sense (h2), expected genetic
advance (GA), and stability of phytic acid (PA), inorganic phosphorus (Pi),
phytic phosphorus (Pp)/Pi relation, yellow pigment (YP), water soluble
phenolics (WSPH) and free protein sulfhydryl groups (PSH) content. The field
trials were carried out at three locations in Serbia, as randomized complete
block design with four replications. The genetic component of variance (?2g)
predominated the genotype ? environment interaction (?2ge) component for: Pi
in bread wheat (3.0 times higher), Pp/Pi in bread wheat (2.1 times higher)
and in durum wheat (1.2 times higher), YP content in bread wheat (2.2 times
higher) and in durum wheat (1.7 times higher), and WSPH content in bread
wheat (1.4 times higher). The relation ?2g/?2ge for Pi content in durum wheat
was equal to one. The ?2ge prevailed ?2g for: PA in bread wheat (1.7 times
higher) and in durum wheat (5.7 times higher), PSH in durum wheat (3.7 times
higher), and WSPH in durum wheat (5.2 times higher). High h2 coupled with
high expected genetic advance as percent of mean (GAM) were observed for: Pi
(93.7% and 26.1%, respectively) in bread wheat, Pp/Pi relation in bread wheat
(92.4% and 20.7%, respectively) and in durum wheat (87.2% and 20.8%,
respectively), YP content in bread wheat (92.6% and 28.0%, respectively) and
in durum wheat (90.7% and 28.1%, respectively), and WSPH content (88.9% and
25.8%, respectively) in bread wheat. PA content in bread and durum wheat had
medium to medium high h2 (50.5% and 77.9%, respectively), and low expected
GAM (9.9% and 3.7%, respectively). GGE biplots with average-environment
coordination (AEC) indicated less stability of durum wheat for PA, WSPH and
PSH content.

Published: February 2017

Objective: The aim of the study was to analyse KIR/HLA profiles and to create
the predictive probabilities for the selection of the most suitable
Hematopoietic Stem Cell Transplantation (HSCT) donor. Materials and Methods:
The study was conducted on 92 patients with malignant hematological deseases
and 181 their first degree relatives, from the region of Vojvodina. HLA and
KIR genotyping was performed by polymerase chain reaction-sequence specific
primers (PCR-SSP) assay. The analysis included the degree of HLA matching
between transplant pairs, number of missing ligands for inhibitory KIR genes,
existence of GvH / HvG ligand-ligand mismatches (specific for C1, C2 or Bw4
ligands) and distribution of C1/C1, C1/C2, C2/C2 HLA ligand groups in
patients. Results: There was no significant differences in HLA frequencies
between donors and recipients as analyzed by pairwise comparison, the
probability of finding HLA identical donor is only 0.154, the probability of
finding the donor with ? 1 KIR-ligand mismatch is 0.939, the probability of
finding the donor with KIR-ligand mismatch for the KIR 2DL1 gene is 0.298,
probability of having favorable C1/C1 and C2/C2 HLA ligand groups is 0.565.
Conclusion: The results of our study could be used as a basis for the HSCT
outcome prediction representing a powerful tool for choosing the most
suitable donor.

Selective tooth agenesis is the most common congenital disorder affecting the
formation of dentition in humans. Both its forms (hypodontia and more severe
oligodontia) can be found either in isolated form and they can be associated
with systemic condition (syndromic tooth agenesis). In addition to previously
known genes (PAX9, MSX1 and AXIN2) mutations in EDA, EDARADD and WNT10 gene
were recently found to be involved in isolated forms of tooth agenesis. The
objective of this study was to characterize the phenotype of affected members
in two large families of Roma origin segregating severe isolated tooth
agenesis with very variable phenotype and to perform mutation analysis of
seven genes with aim to find causal mutation. 26 family members were
clinically examined and coding regions of seven genes (MSX1, PAX9, AXIN2,
EDA, EDAR, EDARADD and WNT10A) were sequenced. With exclusion of third
molars, average number of missing teeth was 8.2 ? 4.9 in family 1 and 7.1 ?
2.3 in family 2. The most frequently missing teeth were maxillary lateral
incisors and first premolars and mandibular central incisors. Sequencing
revealed four potentially damaging variants (g.Ala40Gly in MSX1, g.Ala240Pro
in PAX9, g.Pro50Ser in AXIN2 and g.Met9Ile in EDARADD); however, none of them
was present in all affected family members. Variable phenotype in both
families examined in this study is in favour of heterogeneous genetic cause
of tooth agenesis in these families: possible interaction of several defected
genes, sequence variants in regulatory regions and additional environmental
factors is assumed.

Published: February 2017

This study was conducted to evaluate 49 advanced lines of winter wheat
(Triticum aestivum L.) for their morphoagronomic traits and to determine best
criteria for selection of lines to be included in future breeding program.
The material was assessed in two years experiment at two locations, using
RCBD design with three replications. Ten quantitative traits: plant height,
number of fertile tillers, spike length, number of spikelets per spike,
number of grains per spike, weight of grain per spike and per plant,
fertility, biological yield and harvest index were evaluated by PCA and
two-way cluster analysis. Three main principal components were determined
explaining 71.391% of the total variation among the genotypes. One third of
the variation is explained by PC1 which reflects the genotype yield
potential. PC2 and PC3 explained 25.22% and 15.49% of the total variance,
mostly in relation to the plant height and spike components, respectively.
Biplot graph revealed strongest positive association between spike length,
number of spikelets and biological yield and between number of tillers,
weight of grains per spike and per plant. Two-way cluster analysis resulted
with a dendrogram with one solely separated genotype, superior for all traits
and two main clusters of genotypes defined with wide genetic diversity
especially between the groups within the second cluster. Genotypes with high
values for specific traits will be included in the future breeding
programmes. Classification of genotypes and the extend of variation among
them illustrated on the heatmap has proved to be practical tool for selecting
genotypes with desired traits in the early stages of the breeding process.

MENINGKATKAN KEMAMPUAN MENULIS MAHASISWA DENGAN PENGINTEGRASIAN POWERS DALAM ASESSMEN PORTOFOLIO ELEKTRONIK
Authors: Eka Sulistia Dewi Pt
Published: February 2017

Penelitian ini merupakan penelitian tindakan kelas yang bertujuan untuk meningkatkan kemampuan mahasiswa dalam menulis dengan mengaplikasikan Strategi POWERS berbasis portopolio elektronik. Penelitian ini dilakukan berdasarkan hasil observasi awal yang berupa interview dan pre-test yang menunjukkan bahwa kemampuan mahasiswa semester 2B yang berjumlah 29 orang di tahun ajaran 2011/2012 di Jurusan Pendidikan Bahasa Inggris dalam menulis paragraf tersebut masih kurang. Dari segi proses, pada awalnya mahasiswa sangat tergantung pada kehadiran dosen dikelas, kurang percaya diri bahkan cenderung subjektif. Namun setelah diberikan tindakan, kepercayan diri mahasiswa semakin meningkat (lebih mandiri), mereka cenderung lebih objektif, terbuka, jujur dan mampu bekerja sama serta mengambil resiko dengan baik. Dari segi hasil menulis, hasil belaar mahasiswa pun mengalami peningkatan. Hal ini dapat dilihat dari meningkatnya skor individu dan rata-rata pada pre-test 25,67 (cukup), 32,17 (bagus) pada post-test 1 dan 36,69 (sangat bagus) pada post-test 2. Peningkatan kemampuan mahasiswa juga berpengaruh pada nilai akhir mahasiswa diakhir semester dimana rata-rata nilai akhir mahasiswa adalah B.
