This article provides an accurate detail of the life history of the bagworms Pteroma pendula (P. pendula) and Metisa plana (M. plana) on oil palm. P. pendula was confirmed to possess four larval stages with no difference in the number of instars and pupal development time between the sexes. Life history of M. plana followed reported by earlier workers of 5-6 larval instars for males and 6-7 for females were used. There was, however, no difference in pupal developmental time and size. Sex ratio for both species was nevertheless 1:1 and more representative rm and _ values were obtained. The last two statistics were nevertheless superior for P. pendula and insects bred in the field. The rm for P. pendula was 0.06459 in the laboratory and 0.07327 in the field while the _ was 1.06672 in the laboratory and 1.07603 in the field; cf the rm. M. plana was 0.04783 in the laboratory and 0.06061 in the field while the _ was 1.04899 in the laboratory and 1.06248 in the field. M. plana clearly had th.....

This study investigates the effect of safety management practices on safety performance in ADNOC in the United Arab Emirates, focusing on the mediating effects of ethical workplace climate and safety culture. Using a quantitative survey research design, a 48- item closed-ended questionnaire with proven reliability and validity was employed. A sample of 357 individuals was selected through simple random sampling participants from the ADNOC employee population. The data were analyzed using Partial Least Squares Structural Equation Modeling. Findings revealed that ethical leadership significantly affects ethical workplace climate (_ = 0.266, p < 0.001), safety culture (_ = 0.359, p < 0.001), and safety performance (_ = 0.124, p < 0.001). Employee engagement significantly impacts ethical workplace climate (_ = 0.357, p < 0.01), safety culture (_ = 0.226, p < 0.01), and safety performance (_ = 0.132, p < 0.05). Effective communication influences ethical workplace climate (_ = 0.132, p < 0.0.....

Modern manufacturing, engineering and service industries have changed radically in modern times due to the explosion in the knowledge-based economy. High-speed and lowcost computing, the development and utilization of large databases to cope with this sudden need, certainly have necessitated sophisticated methods to meet new demands. We believe that industrial mathematics is one of the enabling factors in realizing and implementing these methods. In this article, it is argued that it is most advantageous to adopt a wideranging perspective of industrial mathematics in research and education. In particular, this can be based essentially on the novel idea of _construction and analysis of models_, a more holistic approach which highlights the importance of industrial mathematics to modern industries and in teaching the programme in institutions of higher learning. Keywords Industrial mathematics, research and education perspectives, construction and analysis of models..

Disruption of the ADG gene in Arabidopsis results in 6% increase of total fatty acids in mature desiccated seeds. A starchless mutant of Arabidopsis thaliana, ADP glucose pyrophosphorylase (adg1-1) has been investigated concerning the lack of starch in its leaves. In this work of metabolic analysis of adg1-1 mutant, there was very little or no starch accumulation throughout seed development. Even though the growth of these mutant plants was delayed, seed development of the mutants did not show much difference from the wild type. In mature desiccated seeds, there was no significant difference in the seed dry weight of the mutant compared to the wild type. The adg1-1 mutant showed a shift in carbon partitioning to fatty acid (FA) and sucrose accumulation. Major changes have occurred in FA 18.0 (stearic), FA 18.1 (oleic) and FA 18.2 (linoleic). In mature seeds of adg1-1, there was a 70% increase in FA 18.2, a 75% increase in FA 18.1 and a 76% reduction in FA 18.0. The results show that th.....

_-N-methylamino-L-alanine (BMAA) is a nonprotein amino acid found naturally in some cyanobacteria and artificial form as chemical product. BMAA is a neurotoxin and once ingested, BMAA can apparently be bound by proteins within the body, resulting in a slow release of free BMAA over years as contaminated proteins is metabolized. This study identified the effects of BMAA on Danio rerio (zebrafish) early development. Hatching success was not affected by BMAA but later developmental stages of embryos were more sensitive to BMAA than embryonic stage. Higher concentrations of BMAA (500 to 50000 _g L-1) caused increases in the egg diameter, yolk sac length and width, and eye length and width of Danio rerio embryos. All investigated BMAA concentrations increased the larval heart rate during the exposure period. Abnormalities and conditions including oedema, helical body, tail deformities, bend body, flat face, eye deficiency and active performance were observed as a result of exposure to BMAA .....

The diimine 2-diacetylpyridine-(1R)-(-)-fenchone azine {fench=NN=CMe}C5H5N (4) was prepared by heating 2-diacetylpyridine with fenchone hydrazone (3) in boiling ethanol in the presence of acetic acid as the catalyst. Treatment of [Mo(CO)4(nbd)], [Cr(CO)4(nbd)] or [W(CO)4(nbd)] (nbd = norbornadiene) with 2-diacetylpyridine-(1R)-(-)-fenchone azine {fench=NN=CMe}C5H5N (4) gave the five-membered chelated N,N bonded carbonylcomplex of (5), (6) or (7), respectively. Treatment of [PdCl2(NCPh)2] with the azine ligand (4) gave the palladium-complex (8). Treatment of (8) with LiBr or NaI gave the metathesis product of (9) or (10), respectively. Treatment of [{(_3-2-MeC3H4)PdCl2}2] with the azine ligand (4) gave the chloride salt which was then isolated as the corresponding PF6 salt (11). Keywords Molybdenum complexes, tungsten complexes, palladium complexes, bidentate N-N ligand complexes, fenchone azine ligand complexes..

Pelan Induk Pembangunan Pendidikan (PIPP) 2006_2010 (Kementerian Pendidikan Malaysia, 2007) berhasrat untuk memastikan bukan sahaja dapat melahirkan guru yang berkualiti malahan untuk memastikan mereka yang berkualiti ini kekal dalam sistem pendidikan negara dan kekal berkualiti di sepanjang tempoh perkhidmatan mereka. Bagi mencapai hasrat ini, standard pengajaran yang berkesan dan berkualiti harus diamalkan di kalangan guru-guru khususnya guru matematik. Kajian ini melibatkan tiga peringkat. Pertama, kajian literatur dilaksanakan secara intensif tentang standard pengajaran matematik yang diperkenalkan di luar negara seperti National Council of Teacher of Mathematics (NCTM, 2000), The Australian Association of Mathematics Teachers (AAMT, 2006) dan Training and Development Agency for School (TDA, 2007). Di Malaysia, Standard Kualiti Pendidikan (2003) dan Standard Guru Malaysia (2007) turut diperkenalkan dalam usaha untuk meningkatkan kualiti guru dalam perkhidmatan dan praperkhidmatan. .....

The main aim of this article is to investigate the application of the quarter-sweep iteration in solving linear Fredholm integral equations of the second kind. The effectiveness of the quarter-sweep iteration concept with Gauss-Seidel iterative method, known as the Quarter- Sweep Gauss-Seidel (QSGS), by using quarter-sweep approximation equation based on quadrature scheme to solve the problem is examined. In addition, the formulation and implementation of the proposed method are also presented. Some numerical simulations are carried out to show that the proposed method is superior compared to the standard method.

This study aimed to examine the impact of expenditure structure i.e. personnel expenditure, public expenditure, capital construction expenditure, goods and services expenditure, capital expenditure, and financial aid expenditure on financial performance as well as the effect of financial support as a mediator in the relationship between expenditure structure and financial performance of local colleges and universities in China. This study adopted the quantitative research approach using panel data regression analysis. The sample size consisted of 31 provinces _ local general colleges and universities and they were selected using a non-probability sampling technique. The secondary data were obtained from the Yearbook of Education Statistics and the Statistical Yearbook of Education Expenditure from 2010 to 2021 in China. Data were analysed using descriptive statistic and panel data analysis. A Pearson correlation analysis showed most significant relationship between expenditure structur.....
