In the search for new examples of systems that self-assemble into cyclic metal–organic architectures, the six isomers of X,Y′-bis(di(1H-pyrazolyl)methane)-1,1′-biphenyl, LXY, and their silver(I) trifluoromethanesulfonate complexes were prepared. Five of the six silver complexes gave crystals suitable for single crystal X-ray diffraction, with only the microcrystalline derivative of 2,3′-bis(di(1H-pyrazolyl)methane)-1,1′-biphenyl, L23, proving to be unsuitable for this analysis. Of the structurally characterized silver(I) complexes, that with L22 showed an unusual trans-spanning chelating coordination mode to silver. At the same time the ligand was also bound to a second silver center giving rise to a cyclic supramolecular isomer with a 22-membered metallacycle. The complex of L34 also gave a cyclic dication but with a remarkable 28-membered metallacycle ring. The remaining three derivatives were polymeric. The results of this study underscore that a 120° angle between dipyrazolylmethyl moieties across aromatic spacers will give rise to a cyclic dication but this is not an exclusive requirement for the formation of cyclic architectures. Also, the supramolecular structures of complexes are assembled via a variety of noncovalent interactions involving the di(pyrazolyl)methyl cation most notably by weak hydrogen bonding interactions involving the methine hydrogen and an oxygen atom of the triflate anion

Maternal child feeding knowledge and practices and growth status of young children aged 6 to 24 months in Kuala Lumpur

This study was conducted to determine the association between maternal child feeding knowledge and practices with the growth status of young children. A total of 102 young children (62 boys and 40 girls) aged between 6 and 24 months old and their mothers participated in this study. A set of structured questionnaire; was used to obtain information on socio-economic, demographic characteristics, maternal feeding knowledge and practices, and anthropometric measurements of the young children. Maternal feeding knowledge was assessed in three different constructs i.e. general nutrition, breastfeeding and complementary feeding. Maternal feeding practice was assessed by examining whether mothers met the WHO guidelines for continued breastfeeding or feeding of milk or milk products, number of feeding times and number of food groups. Anthropometric measurements of the children such as weight and recumbent length were obtained using TANITA weighing scale and wooden measuring board, respectively. The anthropometric measurements were then compared to the National Center for Health Statistics (NCHS) reference. The results indicated that 18.6% (n=19) of the young children were significantly underweight, 16.7% (n=17) mildly underweight, and 3.9% (n=4) were overweight. The percentage of children with significant and mild wasting were 17.6% (n=18) and 32.4% (n=33) respectively, while 14.7% (n=15) and 34.3 (n=35) were significantly and mildly stunted respectively. Maternal feeding data showed that the mean of maternal feeding knowledge score in the three constructs were 6.73±0.18, 5.97±0.19 and 6.57±0.18, for general nutrition, breastfeeding and complementary feeding respectively. The total score for each construct was 10. The mean total knowledge score obtained was 19.26±4.12. Maternal feeding practice data indicated that 97.1% (n=99) of the mothers continued breastfeeding or feeding milk or milk products, 33.3% (n=34) of the children were fed the recommended minimum number of times, and 81.4% (n=83) of the children were fed the recommended minimum number of food groups. Statistical test on the association between maternal child feeding knowledge and practices with the growth status of young children will be further conducted. Maternal nutritional knowledge and child feeding practices should not be overlooked as factors that may influence growth status of young children

Nutritional status of Rohingya children in Kuala Lumpur

The Rohingya is a group of refugees from Myanmar who have been residing in Malaysia since the 1980s. At present, there is no published information on health and nutritional status of refugee children in Malaysia. This study was conducted to assess nutritional status of the Rohingya children aged 6 months to 12 years old (N=87) and to determine the associations between nutritional status with socio-demographic, dietary diversity and health (birth weight, immunization and childhood illness) variables. Children were measured for weight and height while their guardians were interviewed for socio-demographic, dietary diversity and health information. About 27.5% of the Rohingya children were underweight, 11.5% stunted, 16.1% thin and 12.6% at risk of overweight and overweight. The percentage of children with low birth weight (< 2.5 kg) and no immunization was 17.8% and 11.5%, respectively. Fever (67.8%) and flu (62.1%) were the most common childhood illnesses reported in previous month with 44-75% of the children with these illnesses did not receive any medical treatment. The mean dietary diversity score was 8.9+3.2 out of a possible 14, with a higher score indicating a more diverse diet. There were significant correlations between frequency of immunization received by the children with weight-for-age-z score (rs=0.27, p<0.05), height-for-age-z score (rs=0.25, p<0.05) and BMI-for-age-Z score (rs=0.24, p<0.05). Height-for-age-z score was also positively correlated with childhood illness score (rp=0.24, p<0.05) and dietary diversity score (rp=0.23, p<0.05) in that children with less common childhood illnesses and variety of foods in the diets had better linear growth. As refugees have limited access to health care services, they are at greater risk of health and nutritional problems

Global sourcing strategy of electrical and electronics foreign multinationals in Malaysia / Siti Halijjah Shariff, Osman Mohamad and T Ramayah

Multinationals will source from within their company (intra) as well as from independent supplier (inter) and these suppliers may be located locally or overseas. This study highlights the percentage of components sourced from intra-domestic, intra-foreign, interdomestic, and inter-foreign sources by electrical and electronic foreign multinationals in Malaysia. These global sourcing strategies were found to be different among the different nationality of the parent company for the electrical and electronic foreign multinationals. However, the dependency on sourcing from parent country or from its subsidiaries in foreign country was not reduced even when the product is at the maturity stage

The solid-state molecular structures of 5 and 7 were confirmed by single crystal X-ray analyses. Compound 5 consists of interesting example of a hexaruthenium interstitial carbido cluster having a tetradentate diphosphine ligand derived from the activation of P–C and C–H bonds of the dppm ligand in 1. The tetranuclear compound 7 consists of a unique example of a non-planar spiked triangular metal fragment of ruthenium [Ru(1), Ru(2) and Ru(3)] unit with Ru(4) being bonded to Ru(1). The μ4-η1:η6:η1-benzyne ligand in this compound represents a previously uncharacterized bonding mode for benzyne. Compounds 5 and 7 do not contain any benzothiophene-derived ligand. The reaction of 4 with benzothiophene gives 2, 3, 5 and 6. Thermolysis of 1 in refluxing toluene gives 2, 3 and 4; none of 5 and 7 is detected in reaction mixture

Reaction of tri(2-furyl)phosphine (PFu3) with [Re2(CO)10−n(NCMe)n] (n = 1, 2) at 40 °C gave the substituted complexes [Re2(CO)10−n(PFu3)n] (1 and 2), the phosphines occupying axial position in all cases.

All new complexes have been characterized by a combination of spectroscopic data and single crystal X-ray diffraction studies
