Effects of biotic and abiotic environmental stimuli on the morphology and biomass allocation of Mimosa pigra L.

The main focus of this study was to examine the morphology of Mimosa pigra, an invasive weed in response to artificial biotic and abiotic stressors. Seedlings of M. pigra were subjected to stressors such as seed sowing density, leaf defoliation and water regime. Comparatively, morphological performance related to different sowing practices differed significantly (p0.05) in morphological performance under different levels of water regime. However, seedlings that received low water (LW) treatment showed better growth performance than seedlings that received high water (HW) treatment, which had the lowest morphological traits and biomass allocation

Peranan Pendidikan Agama dalam Pembentukan Etika Sosial Persaudaraan dan Perdamaian (Studi di Malaysia dan Indonesia)

The study was conducted to investigate the Islamic Education role in some regions in Indonesia andMalaysia. Social conflicts remained an unresolved problem for both Indonesia and Malaysia. Thetwo countries faced cases of violence, graft, juvenile delinquency, ethical and moral violation inalmost all parts of the country. In addition, the number of the cases was continuously increasingevery day. In response to the facts, the role of Islamic Education in shaping morality, ethics, andpersonality was certainly questionable. Therefore, Islamic theologians, including Islamic educationteachers, were expected to improve their role in shaping public moral and ethics through theIslamic Education

Weed survey in different cultural practice in Seberang Perai and Muda Rice Fields in Northern Malaysia

A correlation between weedy species composition and 4 different planting practices in Peninsular Malaysia was being investigated from September 2011 – January 2012. Through this study, the noxious and competitive weed of rice were identified and counted, which should be helpful in developing a more sustainable weed control and management. This study was conducted at 24 different rice field covering four types of planting practices in Seberang Perai and MUDA area, namely wet seeding, water seeding, manual transplanting and mechanical transplanting method, using 0.5 x 0.5 m size quadrat with 20 samples for each field during rice at tillering to heading stage. A total of 27 weed species belonging to 14 families composing of 10 broadleaved, 8 grasses, 7 sedges and 2 submerged weed group were recorded. The dominance weeds species in four planting practices at both areas is Oryza sativa complex (weedy rice). Different dominance weed group observed in both areas due to different planting practices, such as in water seeding practice, broadleaved such Limnochoria flava and Monocharia vaginalis showed the highest I.V. for both areas, for wet seeding practice Echinochloa crus-galli and Leptochloa chinensis under grasses group have the highest I.V. and for manual and mechanical transplanting practice both have the same weed group which is Leptochloa chinensis.

Effect of Artificial Defoliation on the Emergence of Foliar Buds of Mimosa Pigra

This study was specified in documenting Mimosa reaction in the state of defoliation on the plants. As defoliation was believed to cause plants experiencing both positive and/or negative effects on its growth performance, thus among the aim of this study is to monitor the emergence of foliar buds in respond with vary level of defoliation intensities. The seedlings were grown singly in polybags up to four leaf stage as. Grown seedlings were randomly subjected under four different defoliation intensities: control (un-defoliated), 25%, 50%, and 100% in which 10 replicates of seedling for each treatment. Experiment was ceased at the 6th month after establishment of plants grew. Results shown that, the effect of defoliation on the production of foliar buds was significantly difference between the treatments (P< 0.05). As compared with 25%, 50% and 100% defoliation, un-defoliated plants showed the highest amount of foliar buds production which is 14 buds. While, there were no differences amount of foliar buds production between 25% and 50% defoliation with 5 foliar buds per plants. Emergence of foliar buds was reportedly lowest in 100% defoliation plant when there were no sign of buds emergence. Results concluded that, the subjected plants of control, 25% and 50% leaves defoliation treatments, were able to performed tolerance effect relative to the induced stressor. Apart from that, experiment revealed that the 100% defoliation has probability of detrimental effect on growth and reproduction of Mimosa seedling as it hindrance the germination of foliar buds

A Review of Surface Texturing in Internal Combustion Engine Piston Assembly

This paper presents a brief review of surface texturing with a focus on piston assembly application. The paper begins with a general discussion on surface texturing and the manufacturing process of micro dimples.&nbsp; Further, it discusses the theory of hydrodynamic lift generation and the effect of parameters of micro dimples texture on the surface-to-surface friction. Finally, the effect of surface texturing on heat transfer is briefly discussed. In pursuits to improve internal combustion engine (ICE) efficiency, tribological improvement of moving surfaces by means of micro surface texturing seems to be one of the way. However, texturing parameters have to be carefully designed as it can cause detrimental effect if the designs are wrong. Studies has shown micro surface texturing at piston ring could reduce friction around 20%-50% compare with un-textured piston ring and also reduce fuel consumption at 4%. Micro Surface texturing could also improve heat transfer between the surfaces to reduce piston slap and lubrication oil temperature. As reports on the surface texturing on friction reduction and heat transfer improvement in piston assembly are relatively scarce, it is suggested that optimization of micro dimple parameters for piston skirt application and its effect on engine tribology and heat transfer characteristics be further investigated

Construction and Psychometrics Properties Identification of Spiritual Intellegence Scale in Moslem Youth

Measurement of spiritual intelligence is an important thing to do in order to map the emotional intelligence possessed by today's Muslim youth. This study aims to compile a scale of spiritual intelligence based on three aspects according to (K. A. Khavari, 2000), namely the spiritual-religious point of view, the viewpoint of socio-religious relations, and the viewpoint of social ethics, as well as presenting existing psychometric properties. Psychometric property analysis in this study included reliability using the alpha-cronbach internal consistency approach, content validity using the Aikens' V content validity approach and item discrimination power. After conducting validity tests by eight experts and field tests on 104 Muslim youths in Indonesia aged 12-24 years, the results of this spiritual intelligence scale consist of 26 valid items and have an Alpha reliability coefficient of 0.856 and all items have discrimination power above 0.2. So that in general this scale has satisfactory psychometric properties and is suitable for use as a measurement instrument and the development of this scale in the future related to the methodological issues discussed in this paper

Student Perceptions and Engagement in Video-based Learning for Microbiology Education

Online learning increases the physical distance between instructors and students and depending on the mode of delivery, it can be challenging to close this gap. To ameliorate this potential for student isolation, instructors need to communicate to students in a variety of ways, blending original online resources with synchronous interactive learning activities. During 2020, 34 lecture videos were created for a large undergraduate microbiology and immunology course offered at The University of Queensland. The teaching team applied a subset of Mayer’s multimedia learning design principles – embodiment, mixed perspectives, segmenting, signalling – to create videos featuring instructor presence, multiple presentation styles, and dynamic pacing. When compared to voice-over presentations created by automated lecture capture software, the outcomes of this design process increased student engagement in video-based learning across the 2020 and 2021 course offerings. Analysis of student perception data collected by online questionnaires and interviews revealed broad agreement with the design principles used for video-based learning. However, their value of on-screen instructor visibility, graphics, and text was variable as a result of individual preferences. Together these findings present a case study in which instructional videos were developed iteratively through the selective application of multimedia design principles and strategic adaptation of existing learning resources

The impact of real estate, inequality and current account imbalances on excessive credit: A cross country analysis

The numerous financial crises in the 20th and 21st century demonstrate the role of excessive credit as the main instigator of financial crises. Could this excessive credit be natural byproducts of lingering economic ailments such as, income inequality, property bubbles and persistent current account imbalances? This study attempts to answer this question by applying the Least Squares Dummy Variable (LSDVC) and dynamic GMM estimations based on the data of ten countries from the year 2004 to 2012. Whilst past literature have investigated the effect of income inequality, dominant real estate sector and current account imbalances on excessive credit separately, this study extends the literature by examining the impact of all three variables on excessive credit aggregately. Our findings tend to indicate that there do exist a positive relationship between all three variables and excessive credit. However, we found that only income inequality and the real estate sector contribute significantly to excessive credit but current account imbalances only marginally do so. We also discovered that the contribution to excessive credit by the banking sector is just about twice the amount of all three variables combined. Our results serve as evidence for policymakers interested in reducing excessive credit by controlling all three variables as well as the banking sector
