    A principal objective in agriculture is to maximise food production; this is particularly relevant with the added demands of an ever increasing population, coupled with the unpredictability that climate change brings. Further improvements in productivity can only be achieved with an increased understanding of plant and crop processes. In this respect, mathematical modelling of plants and crops plays an important role. In this paper we present a two-scale mathematical model of crop yield that accounts for plant growth and canopy interactions. A system of nonlinear ordinary differential equations (ODEs) is formulated to describe the growth of each individual plant, where equations are coupled via a term that describes plant competition via canopy-canopy interactions. A crop of greenhouse plants is then modelled via an agent based modelling approach in which the growth of each plant is described via our system of ODEs. The model is formulated for the African drought tolerant legume bambara groundnut (Vigna subterranea), which is currently being investigated as a food source in light of climate change and food insecurity challenges. Our model allows us to account for plant diversity and also investigate the effect of individual plant traits (e.g. plant canopy size and planting distance) on the yield of the overall crop. Informed with greenhouse data, model results show that plant positioning relative to other plants has a large impact on individual plant yield. Variation in physiological plant traits from genetic diversity and the environmental effects lead to experimentally observed variations in crop yield. These traits include plant height, plant carrying capacity, leaf accumulation rate and canopy spread. Of these traits plant height and ground cover growth rates are found to have the greatest impact on crop yield. We also consider a range of different planting arrangements (uniform grid, staggered grid, circular rings and random allocation) and find that the staggered grid leads to the greatest crop yield (6% more compared to uniform grid). Whilst formulated specifically for bambara groundnut, the generic formulation of our model means that with changes to certain parameter's, it may be extended to other crop species that form a canopy.

    The toddler stage is a golden period and at the same time a critical period for a child, since he / she will experience rapid brain growth and development so that he/ she need sufficient nutrition intake. Toddler's abnormal growth and development are usually found in low economic community because they cannot afford to provide their need for basic food for their toddler's growth and development. The objective of the research was to analyze toddler's growth and development according to family's economic status. The research used descriptive analytic method with cross-sectional design. It was conducted at Limau Manis Village, Tanjung Morawa Subdistrict, Deli Serdang Regency, from January to June 2016. The population was 1899 toddlers, and 113 of them were used as the samples, taken by using simple random sampling technique. The data were gathered by using questionnaires to find out toddler's growth and development according to family's economic status. The result of univariate analysis showed that 57 toddlers (50.4%) had abnormal growth and development. The result of bivariate analysis with chi-square test showed that there was the correlation of toddler's growth and development with economic status (p value=0.004), women's care pattern (p value=0.028), and environmental sanitation (p value=0.01). Therefore, empowerment of family's economy through the development of family's nutrition portfolio is necessary.

    The World Health Organization declared COVID-19 a global pandemic on the 11th of March 2020, but the world is still reeling from its aftermath. Originating from China, cases quickly spread across the globe, prompting the implementation of stringent measures by world governments in efforts to isolate cases and limit the transmission rate of the virus. These measures have however shattered the core sustaining pillars of the modern world economies as global trade and cooperation succumbed to nationalist focus and competition for scarce supplies. Against this backdrop, this paper presents a critical review of the catalogue of negative and positive impacts of the pandemic and proffers perspectives on how it can be leveraged to steer towards a better, more resilient low-carbon economy. The paper diagnosed the danger of relying on pandemic-driven benefits to achieving sustainable development goals and emphasizes a need for a decisive, fundamental structural change to the dynamics of how we live. It argues for a rethink of the present global economic growth model, shaped by a linear economy system and sustained by profiteering and energy-gulping manufacturing processes, in favour of a more sustainable model recalibrated on circular economy (CE) framework. Building on evidence in support of CE as a vehicle for balancing the complex equation of accomplishing profit with minimal environmental harms, the paper outlines concrete sector-specific recommendations on CE-related solutions as a catalyst for the global economic growth and development in a resilient post-COVID-19 world.

    In vitro growth and multiplication of taro [Colocasia esculenta var. antiquorum cv. Keladi Birah] was improved considerably, when primary shoot apices were cultured on two modifications of Linsmaier and Skoog [1965] medium, containing 5.5 mg 1(-1) naphthaleneacetic acid and 0.2 mg 1(-1) kinetin or 1.85 mg 1(-1) naphthaleneacetic acid and 2 mg 1(-1) kinetin and supplemented with 10(-4) or 10(-3) mol·1(-1) of polyamine spermine or either of the precursors of polyamine putrescine-arginine and ornithine. Plantlets were regenerated directly from primary shoot apices, axillary buds and protocorm-like bodies [PLB]. Frequency of plantlet regeneration, rate of development and growth in height of main plantlets were enhanced by the addition of arginine and ornithine to the media. Secondary plantlet formation from axillary buds and PLB were promoted by spermine and arginine respectively.

    It is ironical to realize that a perfect and free nutritional product, individually produced and naturally distributed to all families, is not universally used. This product is of course breast milk that nurtures the optimal health, growth and development of the human young. Breast milk also protects infants and young children from and prevents diseases in the short and long term. (Copied from article)

    Small and medium scale enterprises (SMEs) act as a promoter of economic development of the developed and under developed nations. Developing countries like Nigeria that, require sustainable economic growth and development must pay attention to the SMEs sectors in order to reduce unemployment, poverty and improve the standard leaving of its society. Unfortunately, in Nigeria, SMEs have underperformed despite that, 90% of the Nigerian businesses are small scales but their contribution to the Nigerian GDP is below 10%. The main reason for this low contribution of SMEs to Nigerian GDP could be attribute to poor funding, lack of management expertise and lack of access to modern technology among others, with proper finance the SMEs can acquire modern technology and employed qualified staff. Thus, this paper focuses on crowdfunding as financial option for Nigerian SMEs. However, the paper is a conceptual framework.

    In this article, the authors propose reference curves for height and weight for school children in the Kuching area, Sarawak. The school children were from primary to secondary schools (aged 6.5 to 17 years old) and comprised both genders. Anthropometric measurements and demographic information for 3081 school-aged children were collected (1440 boys and 1641 girls). Fitted line plots and percentiles for height and weight (3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles) were obtained. The height of school boys and school girls were almost similar at the start of their school-going age. For school girls, height and weight values stabilized when they reached 16 or 17 years old but kept increasing for school boys. School boys were taller than school girls as they entered adolescence. Height differences between school boys and school girls became significantly wider as they grew older. Chinese school children were taller and heavier than those of other ethnic groups.

    Government expenditure plays an important role in the country’s economic growth. Budget allocations through the annual budget presented have their strategies to ensure that the allocated budget can improve the growth and development in Malaysia and also can be enjoyed by all Malaysian. The government’s expenditure has contributed to the expansion of this country’s development from various sectors. However, there are various problems involving government expenditure such as low level of health, homeless poor people, weak public transportation and illegal immigrants. The purpose of this study is to examine the relationship between government expenditure on health, education, housing, transportation and defence sectors towards economic growth. The data used is secondary data from 1980-2017 for 38 years from the Department of Statistics, Malaysia and World Bank Data. The method used in this study is Descriptive Analysis and Autoregressive Distributed Lagged Model (ARDL). The result showed that economic growth and government expenditure on health, education, transportation, and defence has a long-run relationship. Therefore, the government should increase more expenditure on crucial sectors such as education, transportation, defence and health that will strengthen economic growth in the long run.

    The Combined Cleft Clinic at the University Hospital, Kuala Lumpur was organised in 1992. The team consists of Plastic Surgeon, Orthodontists, Speech therapist, Ear, Nose and Throat Surgeon, Audiologist, medical officers and the nurses. We attend the clinic on a regular basis. Specialists from other medical and dental disciplines as well as the members of the Cleft Lip and Palate Association of Malaysia (CLAPAM) do occasionally participate in this set-up.The team members formulate treatment plans for each cleft patient, monitor the patient's growth and development and manage the patient at different stages according to the individual needs. To date, the idea of team approach and an establishment of a centre towards management of cleft patients seem to be the most ideal as the patients are benefiting total treatment and care from various specialists from only one place. The experience of University Hospital as a centre for cleft patients is discussed.

    A sample of 204 handicapped children below 12 years of age consisting of 121(59.3%) males and 83 (40.7%) females who were classified into various types of mental and physical handicaps, were surveyed in April and May 1996. The majority of those with mental handicaps were Down Syndrome while those with cerebral palsy were the mostfrequent cause of physical handicaps. A structured questionnaire was used for interviewing the children parents to evaluate their attitude towards their handicapped children. The majority of the parents expressed their opinions that having handicapped children was not a burden to them although these children had to be given more attention. However, a significant minority felt that the child would be afinancial burden to the family and that he/she would restrict the social life of the family. The majority of the children were sent to school, as parents felt it was their duty to do so. For those children not attending school, the majority of parents felt that the children would not benefit by going. The others could not do so because offinancial constraints or because of the distance between home and school. For these children, provid-ing hostel facilities in a boarding school could be the answer. This study shows that parental love and support plays a major role in ensuring optimal growth and development of a handicapped child

    Educational environment of an institution is the environment experienced or perceived by students and teachers. Individual students and teachers will respond differently to these subtle elements in their learning experience. Curriculum's most significant manifestation and conceptualisation is the environment. There is a proven connection between the environment and the valuable outcomes of students' achievement, satisfaction and success. If one wants to describe, assess or get a handle on the curriculum in a medical school, then the educational and organisational environment or total milieu associated with the curriculum and the medical school needs to be studied. Educational environment is one of the most important determinants of an effective curriculum. Educational environment fosters scholarly or intellectual activities; it encourages friendliness, co-operation and supportiveness. It also fosters the learning, growth and development of students. Students' perceptions of their educational environment are a useful basis for modifying and improving the quality of educational environment. Several research groups over the years have attempted to identify and quantify the presence and impact of rather intangible aspects of a learning environment. Each study has used different survey questionnaires to solicit student reactions.

    Yield performance in wheat (Triticum aestivum) was compared under crop residue, tillage system and nitrogen rate treatments in cereal based cropping system. The experiments were conducted at Agronomy Research Farm, The University of Agriculture, Peshawar, in 2009-2010 and 2010-2011. Chopped crop residue on dry matter basis (5 t ha1-) of legume (Vigna unguicuata, var. Ebney) and cereal (Zea mays, var. Azam) was applied in main plots with no residue treatments and plowed with Mould Board (MB) and Cultivator as deep and shallow treatments, respectively. A month after the crop residue and tillage system treatments, field was uniformly plowed with cultivator and wheat was sown with drill in rows 25 cm apart in the month of November on both years. Both P2O55 and K2O (80 and 40 kg ha , respectively) were applied uniformly to all fields before sowing. Nitrogen as subplot treatment (0, 40, 80, 120 and 160 kg ha-1) was applied in two splits, half at 15 and the other half at 45 days after sowing with uniform cultural practices for crop growth and development. Compared to year 1, crop of year 2 showed better phenology with extended life cycle (LC). On two years average across tillage and N treatments, biological yield did not change (p<0.05) under the residue but did report lower at no-residue treatment. Nonetheless, grain yield showed a significant (p<0.05) change with the highest in legume followed by cereal and the lowest in no-residue treatments. A non-significant tiller number and significant variations in grain weight and spike m-2 were observed that influenced the grain and biological yield differently. Deep than shallow tillage resulted in better traits, which returned better biomass and grain yield. Nitrogen application from control to every increment showed a significant (p<0.05) improvement in all observations contributing in yield. The study confirms the significance of legume vs. cereal over no-crop residue incorporated through deep tillage system with optimum N (120 kg ha-1) in cereal-based cropping system for sustainable performance to sustain soil C:N for future production.

    A glioma, especially a grade IV glioblastoma, is a malignant tumour with a poor prognosis despite growing medical advancements. Researchers have been looking for better and more effective treatments targeting the molecular pathways of gliomas due to glioblastomas' ability to develop resistance to chemotherapies. Moreover, glioma stem cells (GSC) contribute to maintaining the glioma population, which benefits from its ability to self-renew and differentiate. Recent research has reported that through the introduction of umbilical cord mesenchymal stem cells (UCMSC) into glioma cells, the growth and development of the glioma cells can be downregulated. It has more currently been found out that UCMSC release extracellular vesicles (EVs) containing miRNA that are responsible for this phenomenon. Therefore, this review analyses literature to discuss all possible miRNAs contained within the UCMSC's EVs and to elaborate on their molecular mechanisms in halting gliomas and GSC growth. This review will also include the challenges and limitations, to account for which more in vivo research is suggested. In conclusion, this review highlights how miRNAs contained within UCMSC's EVs are able to downregulate multiple prominent pathways in the survival of gliomas.

    Endophytic bacteria are harmless in most plant species; and known to boost the growth and development of the host plants probably by secreting growth hormones. The isolation, identification and screening of endophytic bacteria for the plant growth regulators like cytokinin are needed to get the leads for their applications in agriculture sector. We describe the isolation and identification of the bacterial endophytes from the leaves of Sambung Nyawa [Gynura procumbens (Lour.) Merr.] and their screening for cytokinin-like compounds. We isolated three endophytic bacteria from the leaves of G. procumbens collected from the forest research institute of Malaysia (FRIM). They were further identified using amplified 16S rRNA gene sequence based method of bacterial identification. The ethyl acetate extracts of the isolates-broth were analyzed using cucumber cotyledon greening bioassay (CCGB) to determine the presence of cytokinin-like compounds. Consequently, the bacterial putative endophytes were identified as Psuedomonas resinovorans, Paenibacillus polymaxa, and Acenitobacter calcoaceticus. Broth-extracts from two (Psuedomonas resinovorans and Paenibacillus polymaxa) of the three putative bacterial endophytes show the positive results in their screening for cytokinin-like compounds using CCGB. Thus, we hypothesize that the bacterial putative endophytes of G. procumbens that produce cytokinin-like compounds might have a role in the growth and development of G. procumbens.

    Introduction: In Malaysia, herbal medicines are used for variety of reasons including health promotion and home remedies during pregnancy and postpartum with Manjakani (Quercus infectoria) as one of the most commonly consumed herbs. Herbal medicines consumption had been linked to heavy metals contamination and transfer from mother to infant and may affect infant’s growth and development. This study aims to (i) determine Manjakani consumption among postpartum mothers, (ii) quantify its heavy metals level, namely lead, cadmium, arsenic and chromium, and (iii) determine health risk associated with its consumption. Methods: A cross-sectional study involving 106 postpartum mothers was carried out in Kuala Lumpur. Six samples of Manjakani were sampled and extracted using microwave digester and analysed using Inductively coupled plasma mass spectrometry (ICP-MS). Non-carcinogenic health risks for herbal medicine consumption were calculated using Hazard Quotient (HQ). Results: Manjakani was consumed by 16% of mothers (n=17). Highest level of the metals was shown by chromium with mean concentration of 4210 ± 1910 ug/kg, followed by lead (170.8 ± 193.2), arsenic (39.3 ± 27.1) and cadmium (7.7 ± 0.76). There were no significant non-carcinogenic health risks with lead, arsenic, chromium and cadmium contamination (HQ < 1). Conclusion: Manjakani is consumed by mothers during confinement period. Heavy metals were quantified in Manjakani although no significant association was observed with socio-demographic characteristics and birth outcomes.

    Saffron (Crocus sativus L.) is an important plant in medicine. The Kashmir Valley (J&K, India) is one of the world's largest and finest saffron producing regions. However, over the past decade, there has been a strong declining trend in saffron production in this area. Plant Growth Promoting Rhizobacteria (PGPR) are free living soil bacteria that have ability to colonize the surfaces of the roots and ability to boost plant growth and development either directly or indirectly. Using the efficient PGPR as a bio-inoculant is another sustainable agricultural practice to improve soil health, grain yield quality, and biodiversity conservation. In the present study, a total of 13 bacterial strains were isolated from rhizospheric soil of saffron during the flowering stage of the tubers and were evaluated for various plant growth promoting characteristics under in vitro conditions such as the solubilization of phosphate, production of indole acetic acid, siderophore, hydrocyanic acid, and ammonia production and antagonism by dual culture test against Sclerotium rolfsii and Fusarium oxysporum. All the isolates were further tested for the production of hydrolytic enzymes such as protease, lipase, amylase, cellulase, and chitinase. The maximum proportions of bacterial isolates were gram-negative bacilli. About 77% of the bacterial isolates showed IAA production, 46% exhibited phosphate solubilization, 46% siderophore, 61% HCN, 100% ammonia production, 69% isolates showed protease activity, 62% lipase, 46% amylase, 85% cellulase, and 39% showed chitinase activity. Three isolates viz., AIS-3, AIS-8 and AIS-10 were found to have the most plant growth properties and effectively control the growth of Sclerotium rolfsii and Fusarium oxysporum. The bacterial isolates were identified as Brevibacterium frigoritolerans (AIS-3), Alcaligenes faecalis subsp. Phenolicus (AIS-8) and Bacillus aryabhattai (AIS-10) respectively by 16S rRNA sequence analysis. Therefore, these isolated rhizobacterial strains could be a promising source of plant growth stimulants to increase cormlets growth and increase saffron production.

    Food insecurity is normally associated with lower socioeconomic status and improper feeding practices which may consequently affect growth and development of young children. This study aims to assess household food security status and its association with child feeding practices and children’s weight status among low income mothers in Terengganu. A cross-sectional study using convenience sampling was conducted at four public maternal and child health clinics (MCH) located in Terengganu. A total of 107 of low-income mothers between ages of 18 to 45 years with net household income less than RM 3000 who has at least one child aged two years and above were recruited. The instruments used were Household Food Insecurity Access Scale (HFIAS), Child Feeding Questionnaire (CFQ) and weight-for-age child growth chart for children’ weight status at aged one year. Descriptive statistic and non-parametric tests were employed (SPSS 20). Majority of the households were food secure (85.0%). Yet, it is also important to note that about 15% of the household had experienced some degree of food insecurity. There was no significant correlation between household food security and all child feeding practice domains. Most of the mothers had children with normal weight (mean Z-score =-0.72+0.99). There was statistically significant association between household food security status and weight of children at one year of age (p=0.01). In conclusion, majority of the households experienced food secure. Household food security were associated with children’s weight status at early age but not correlated with parent’s child feeding practice.
