Comparing the effects of sodium tripolyphosphate (STPP) concentrations of 0.2% and 0.4% on beef semitendinosus is the objective of the current investigation. The samples were cooked at varied temperatures (45+60℃ and 45+70℃) and times (1.5+1.5 h and 3+3 h) using staged cooking. The colour properties, cooking loss, water retention, shear force, water-holding capacity, sarcoplasmic, and myofibrillar solubility, and total collagen were investigated. The cooking time and temperature affected the water-holding capacity, cooking loss, CIE L*, CIE a*, CIE b*, myofibrillar, and sarcoplasmic solubility, with lower temperature and short time having the lower detrimental effect. However, the significant effect can be intensified after the addition of STPP with higher water-holding capacity and tender meat obtained with 0.4% phosphate concentration at any cooking conditions. The STPP lowered the collagen content and increased the protein solubility of myofibrillar and sarcoplasmic, which this degradation is used as a good indicator of tenderness.

Nurul Huda Razalli,Chui Fen Cheah,Nur Mahirah Amani Mohammad,Zahara Abdul Manaf 한국영양학회 2021 Nutrition Research and Practice Vol.15 No.5

BACKGROUND/OBJECTIVES: While plate waste has been widely investigated in hospitals, there have been minimal studies specific to the texture-modified diet (TMD). This study aims to determine the percentage of plate waste among patients prescribed with TMD and its contributory factors. SUBJECTS/METHODS: This was a single-centre study conducted in the university hospital on three types of TMD (blended diet, mixed porridge, minced diet) during lunch and dinner meals. Weighing method and visual estimation method assisted by digital photograph were adopted in this study. Face to face interview was carried out to investigate on 1) the food/food service quality factors in terms of patients" satisfaction level towards sensorial quality of food and food services provided and 2) the clinical/external factors including appetite, the provision of oral nutrition support, time taking the diet, the need for feeding assistance and the length of hospital stay. RESULTS: The mean percentage of overall plate waste of 95 patients receiving TMD was high (47.5%). Blended diet was identified as the most wasted diet (65%) followed by minced diet (56%) and mixed porridge (35%). Satisfaction level among patients was moderate. Patients on TMD in general had higher satisfaction level on the aspect of food service as compared to food quality. Substantial association between sensorial qualities of food and plate waste were varied according to individual TMD type. A multiple linear regression showed that only the satisfaction level toward the aspects of appearance and variety of foods were the predictors of TMD plate waste (R² = 0.254, P < 0.05). CONCLUSIONS: A significant relationship between the percentage of plate waste and the overall satisfaction level of patients receiving TMD suggests that vigorous strategies are needed to reduce the food waste of TMD which will lead to a better nutritional status and clinical outcomes among the patients.

One size does not fit all: an analysis of the corruption preventative approach of the Anti-Corruption Commission (ACC) in Bangladesh

Nurul Huda Sakib 서울대학교행정대학원 2019 Asian Journal of Political Science Vol.27 No.2

This paper argues that the global citizens’ engagement movement against corruption does not always succeed in developing countries, such as Bangladesh. Drawing on the case of the preventative strategies of the Anti-Corruption Commission (ACC) in Bangladesh, this paper shows that government-driven citizens’ engagement processes through community-based organisations (CBOs) are a ceremonial adaptation in response to isomorphic pressure from the donors. The outcomes from isomorphic pressure suggest that such donor-funded actions produce ‘isomorphic mimicry’ of successful corruption prevention programmes from other countries that do not succeed in the recipient country. A micro-level analysis based on interviews with stakeholders in Bangladesh demonstrates why isomorphic mimicry has failed to produce a robust anti-corruption prevention approach in Bangladesh.

This study deals with the generalization of the Elliptic Restricted Three-Body Problem (ER3BP) by considering the effects of radiation and oblate spheroid primaries. This may illustrate a gas giant exoplanet orbiting its host star with eccentric orbit. In the three dimensional case, this generalization may possess two additional equilibrium points ($L_{6,7}$, out-of-plane). We determine the existence of $L_{6,7}$ in ER3BP under the effects of radiation (bigger primary) and oblateness (small primary). We analytically derive the locations of $L_{6,7}$ and assume initial approximations of (${\mu}-1$, ${\pm}\sqrt{3A_2}$), where ${\mu}$ and $A_2$ are the mass parameter and oblateness factor, respectively. The fixed locations are then determined. Our results show that the locations of $L_{6,7}$ are periodic and affected by $A_2$ and the radiation factor ($q_1$).

Crinum asiaticum and Hymenocallis littoralis, commonly known as spider lilies are bulbous perennial and herbaceous plants that widely planted in Malaysia as ornamental. During 2015-2016, symptom of leaf blight was noticed on the hosts from several locations in Penang. The symptom appeared as irregular brown to reddish lesions surrounded by yellow halos. As the disease progressed, the infected leaves became blighted, dried, and fell off with the presence of black microsclerotia and pycnidia on the lesions parts. The present study was conducted to investigate the causal pathogen of leaf blight on C. asiaticum and H. littoralis. Based on morphological characteristics and DNA sequences of internal transcribed spacer (ITS) region and translation elongation factor 1-alpha (TEF1-a) gene, the causal pathogen was identified as Macrophomina phaseolina. Phylogenetic analysis of combined dataset of ITS and TEF1-a grouped the isolates studied with other isolates of M. phaseolina from GenBank. The grouping of the isolates was supported by 96% bootstrap value. Pathogenicity test proved the role of the fungus in causing leaf blight on both hosts.

Meliha Oktav Bulut,Nurul Huda Sana 한국섬유공학회 2018 Fibers and polymers Vol.19 No.9

In this study, the effects of corona plasma process on the dyeability and certain physical properties of woolen fabric were investigated. For this purpose, acid and 1.2 metal complex dyes, which are the most applicable dyes in the wool market were used. The patterns were examined to assess their dyeability, wettability, pilling resistance, alkali solubility, and strength values. The surface morphology and chemical structures were tested by X-ray photoelectron spectroscopy and alkali solubility analyses and also scanned by electron microscopy. Hydrophility indexes of the dyes that were used were determined. With the results of the experiments, their hydrophobic index is of vital importance, which is a factor for plasma efficiency on color depth. By using plasma treatment on woolen fabric, it is achievable to get a product with high hydrophility and pilling resistance values, dyeability, and less burdened dyeing bath.

( Nor Hamizah Shafiee ),( Nurul Huda Razalli ),( Norfilza M. Mokhtar ),( Eunice Tan ),( Raja Affendi Raja Ali ) 대한장연구학회 2022 Intestinal Research Vol.20 No.1

Background/Aims: Substantial proportions of patients with constipation-predominant irritable bowel syndrome (IBS-C) linked their symptoms with particular intake of foods. However, there is lack of current data regarding the intake among IBS-C patients before any dietary interventions. Thus, this study aimed to evaluate the dietary adequacy among IBS-C against the standard recommended nutrient intake (RNI) and healthy controls. Methods: A retrospective case-control study was conducted involving IBS-C patients and healthy control subjects. A validated 126-food items frequency questionnaire was administered to all the subjects to assess their dietary intake, guided by dietitians. The calculated nutrients intake for IBS-C patients was then compared against the standard RNI and healthy controls. Results: A total of 306 subjects were recruited, among which 218 were diagnosed with IBS-C and 88 were included as healthy controls. IBS-C patients had significantly lower intake of wholegrain products, fried foods, dairy products, fruits, and vegetables compared to healthy controls. The daily intake of energy, certain macronutrients, and micronutrients among IBS-C patients was significantly lower than the healthy subjects. Less than 5% of IBS-C patients and healthy subjects achieved the standard recommendation for dietary fiber. Also, various vitamin intake (B₁, B₂, B₆, folate, B₁₂, E, K, and potassium) among IBS-C patients did not meet the standard RNI. Conclusions: Dietary intakes of IBS-C patients did not meet the recommended intake for Malaysian and showed the nutritional inadequacies compared to the control subjects. Our study highlighted the importance of dietary evaluation prior to planning strategies for dietary intervention targeting IBS-C patients. (Intest Res 2022;20:124-133)

Evaluation of Air Pollution Tolerance, Anticipated Performance, and Metal Accumulation Indices of Four Tree Species in Dhaka, Bangladesh for Air Pollution Management

Mohammad Enayet Hossain,Saif Shahrukh,Muhammad Nurul Huda,Md. Mominul Islam,Shahid Akhtar Hossain 한국대기환경학회 2021 한국대기환경학회 학술대회논문집 Vol.2021 No.10

Urban air quality is one of the major issues in cities worldwide, with airborne particulate matter (PM) being recognized as one of the most harmful pollutants vis-à-vis human health. In cities, roadside vegetation is exposed to all types of air pollutants, including a wide variety of particulates-borne toxic compounds. Information on plants’ tolerance towards air and PM pollution and plant-pollutant interactions is vital for screening of suitable stress-tolerant plants as a sustainable green-filtration unit. An investigation was undertaken to assess the tolerance or sensitivity of four roadside trees (Ficus benghalensis, Ficus religiosa, Mangifera indica, and Polyalthia longifolia) towards air pollutants, including particulates. The four species were sampled from four different locations of Dhaka, Bangladesh. Air pollution tolerance index (APTI) was assessed using the total chlorophyll content, ascorbic acid content, relative water content, and the pH of the extract from the leaves of the studied plants. The results were compared with similar species at a non-polluted site in a nearby area having a similar soil-climate complex. Concentration of selected biochemical parameters was found to be lower in some plant species grown at the polluted site than at the non-polluted site. The total chlorophyll content showed a decreasing trend with the increasing particulate matter loads. Different tolerance orders of species were found at the four sampling sites, which was possibly due to the varying level of air pollution in those sampling sites. APTI of the investigated plants ranged from 10.31 to 12.51 meaning they were either sensitive or intermediately tolerant. M. indica was found to be intermediately tolerant in three sampling sites. The results indicated that these evergreen species are good indicators of air pollution and can be used as an early warning tool for air pollution level that is harmful to human health. Anticipated performance index (API) was also calculated to assess the overall performance of a plant in a particular region where some socioeconomic and biological characteristics were taken into consideration. From the API, M. indica achieved the highest score (68.75%) amongst the selected plant species irrespective of different sites. The accumulation of heavy metals (Cd, Cr, Pb, and Ni) on the leaves of four tree species were investigated, and a predictive foliar metal accumulation index (MAI) was developed. F. benghalensis was found to have the highest MAI value (13.60). Based on these three indices, the most suitable plant species for green belt development in urban areas were identified and recommended for long-term air pollution management.
