摘要： The depletion of log resources encourages research into alternative ways to sustain the wood supply.Therefore,the 4-year-old Rubber Research Institute of Malaysia(RRIM)clones series,RRIM 2020 and RRIM 2025,were chosen as potential raw materials for particleboard in this study.The purpose of this study was to assess the effects of planting density and rubber tree clones on the mechanical and physical properties of single-layer particleboard.The planting densities used were low,moderate-low,moderate-high,and high,representing 500,1000,1500,and 2000 trees/ha,respectively.Prior to manufacturing,the RRIM 2000 series clone trees were harvested,cut,chipped,flaked,and screened.The mechanical and physical properties were evaluated in accordance with the Japanese Industrial Standard(JIS A 5908-2003).The findings revealed that both planting density and clone had a significant impact on the mechanical and physical properties of particleboard with a thickness of 10 mm and a density of 700 kg/m3.RRIM 2020 specimens with low planting density had superior modulus of elasticity(MOE),modulus of rupture(MOR),and internal bonding(IB)values of 2415,19,and 1.7 MPa,respectively.Furthermore,moderate-low planting density demonstrated the lowest thickness swelling(TS)and water absorption(WA)values and was comparable to control particleboard from commercial clone Prang Besar(PB),PB260.In terms of rubber clones,RRIM 2020 particleboard met the minimum requirements of the JIS standard for mechanical properties and outperformed RRIM 2025.This study recommended a low planting density of 500 trees/ha and the RRIM 2020 clone as a suitable raw material for particleboard manufacturing with a ten percent urea formaldehyde resin content.

摘要： With the continuous attention of the physical education curriculum,the mainland of China and Hong Kong,China is making continuous progress in the exploration of physical education curriculum standards.Through the comparison of the framework,content,and evaluation of curriculum standards,the two curriculum standards have their own similarities and characteristics.This paper compares the primary school physical education curriculum standards between Mainland China and Hong Kong to provide a reference for the further improvement of primary school physical education and health curriculum standards in mainland China.

摘要： BACKGROUND In the six Gulf Cooperation Council countries(GCCCs),Bahrain,Saudi Arabia,Kuwait,Oman,Qatar and the United Arab Emirates,breast cancer(BC)is the greatest cause of cancer incidence and mortality.Obesity and physical inactivity are established risk factors for BC globally and appear to be more of a problem in high income countries like the GCCCs.AIM To determine whether obesity and physical inactivity are associated with BC incidence in the GCCCs using the United Kingdom as a comparator.METHODS This systematic review was carried out according to PRISMA guidelines.A cancer registry and a statistical data search was done to identify the BC incidence over the past two decades and the prevalence of obesity and physical inactivity in the GCCCs.Additionally,a systematic search of the databases,MEDLINE,Web of Science,and PubMed between 1999 and 2019 was performed to determine whether obesity and physical inactivity are risk factors for BC in the GCCCs.All papers were critically appraised according to their research methods and were assessed for quality and risk of bias.RESULTS BC was the top malignancy in each GCC country.Women tended to be diagnosed with BC at a younger age than women in the United Kingdom.The greatest 10-year increase in BC incidence was seen in Saudi Arabia(54.2%),,approximately seven times the rate of increase seen in the United Kingdom(7.6%).The prevalence of obesity and physical inactivity was greater in all the GCCCs in comparison to the United Kingdom.A total of 155 full studies were reviewed of which 17 were included.Of those,eight looked at the prevalence of obesity and physical inactivity in the Gulf States and nine looked at these as risk factors for BC.Only one study found an association between BC and obesity(odds ratio=2.29).No studies looked solely at the link between physical inactivity and BC.CONCLUSION The prevalence of obesity and physical inactivity was high within the GCCCs,but the majority of the included studies found no positive correlation between obesity or physical inactivity and BC.A high proportion of women in this study were pre-menopausal which could contribute to the negative findings.

摘要： Rainfall is one of the most important factors contributing to landslides, and gentle bedding incline, high-rainfall induced landslides are common throughout the world. Field observations and theoretical analyses have been used to assess slope instability caused by permeability variation. In this study, the influence of rainfall infiltration on gentle bedding incline slope behaviour was investigated using a centrifuge physical simulation test. The magnitude, pattern and development of pore water and earth pressure at the interface;the shear failure surface features;and the corresponding deformation and failure processes were considered. A model with interbedded sand and mud was created, and a centrifuge was used to simulate both natural and rainfall conditions. The weak intercalation was composed of single-material silty clay, and the landslide mass was composed of red-bed sandstone. A combination of photography, pore water pressure measurements and earth pressure measurements were used to examine the relationship between the pore water pressure, earth pressure and failure modes. When the slope experiences overall instability, the curves of the earth pressure and pore water pressure dramatically decrease. The results reveal that the failure shear surface largely depends on the differential creep caused by the properties of the rock mass and the rainfall infiltration.

摘要： Rhythmic oscillatory patterns sustain cellular dynamics, driving the concerted action of regulatory molecules, microtubules, and molecular motors. We describe cellular microtubules as oscillators capable of synchronization and swarming, generating mechanical and electric patterns that impact biomolecular recognition. We consider the biological relevance of seeing the inside of cells populated by a network of molecules that behave as bioelectronic circuits and chromophores. We discuss the novel perspectives disclosed by mechanobiology, bioelectromagnetism, and photobiomodulation, both in term of fundamental basic science and in light of the biomedical implication of using physical energies to govern (stem) cell fate. We focus on the feasibility of exploiting atomic force microscopy and hyperspectral imaging to detect signatures of nanomotions and electromagnetic radiation (light), respectively, generated by the stem cells across the specification of their multilineage repertoire. The chance is reported of using these signatures and the diffusive features of physical waves to direct specifically the differentiation program of stem cells in situ, where they already are resident in all the tissues of the human body. We discuss how this strategy may pave the way to a regenerative and precision medicine without the needs for (stem) cell or tissue transplantation. We describe a novel paradigm based upon boosting our inherent ability for self-healing.

摘要： Environmental conditions including light are considered a critical element of chicks well-being. The aim of the present study was to investigate the effect of LED light on the physical traits of chicks. We took forty-one-day-old chicks and randomly separated it into two groups. The chicks in the first group were reared under the effect of incandescent lamp light and in the second one were under the effect of white LED lighting. Chicks were daily monitored for individual chick body, weight gain, feed intake, feather color and fear responses. The distance between chicks and source of light was 50 cm. Student’s t-test test was used for statistical evaluation at p < 0.05 level. The results of the current study showed that chicks reared under incandescent light bulb had significantly higher body weight compared with chicks reared under LED light. The magnitude of body weight in LED group was lower (1192.75 ± 149.9 g) compared to incandescent light group (1307.75 ± 110.5 g). The obtained results revealed that LED light reared chicks were more active;it showed long mobility duration and high levels of exploration in the farm as compared to those in incandescent light group. The results also indicated that incandescent light chicks were less fearful than LED chicks. Furthermore, the study showed that LED light reared chicks have pale pink combs and white feathers that cover all over the body. On the other hand, incandescent light reared chicks have dark red combs and whitish-yellow feathers that cover certain areas of the body especially chick wings, tail and head.
