Eugenol (4-allyl-2-methoxyphenol), the major secondary metabolite of clove (Syzygiumaromaticum) has been widely used in medicine due to its biological properties. The present study was designed to investigate the effects of eugenol on the fasting blood glucose (FBG)and histological pattern of pancreas and liver of alloxan-diabetic rats. Eugenol was extracted and isolated from cloves leaves oil and further was screened by in vivo model of diabetic rats. Diabetic condition was induced with alloxan monohydrate (125 mg/kgbw, iv). Rats were divided into five groups: eugenol with 3 serial doses of 5 mg/kgbw (D1), 10 mg/kgbw(D2), 15 mg/kgbw (D3); positive control-glibenclamid 1.35 mg/kgbw (D4); normal control (D5) and negative control-CMC-Na 0,5% (D6). The treatments were performed daily for 15 days. Fasting blood glucose (FBG) level of D1 to D5 before treatment was404, 363, 319, 313, and 113 mg/dL, respectively; and after 15 days was reduced to be 294, 181, 97, 112, and 94 mg/dL, respectively. Statistically, blood glucose reduction of D1, D2, and D3 were significant (P>0,05) compared to positive control. D3 seems to be effective dose causinghypoglycaemic. Histological studies of pancreas and liver indicated that D3 mayimprove the morphology of Langerhans and liver into normal condition.Eugenol (4-allyl-2-methoxyphenol), the major secondary metabolite of clove (Syzygiumaromaticum) has been widely used in medicine due to its biological properties.

Transversal displacement of freight wagons bogies 货车转向架的横向位移
O. Fomin, A. Shvets, Vladimír Hauser, P. Prokopenko
This paper is focused to the study of the influence of lateral displacement of open box type cargo wagon bogies on their main dynamic indicators and indicators of the interaction of rolling stock with rails. The theoretical study was carried out using the model of spatial oscillations of the five wagons set. During the calculations, the change in the angle of rotation of the central axis of the wagon body was considered, which leads to a mutual transverse displacement of the bogies. As a result of research, the dependences of the indicated indicators of a freight wagon on the magnitude of the angle of rotation of the body and speed of movement were obtained.This paper is focused to the study of the influence of lateral displacement of open box type cargo wagon bogies on their main dynamic indicators and indicators of the interaction of rolling stock with rails.

Mechatronic system of control position of wheel pairs by railway vehicles in the rail track 铁路车辆在轨道上控制车轮对位置的机电系统
E. Mikhailov, J. Gerlici, S. Kliuiev, S. Semenov, T. Lack, K. Kravchenko
The paper considers the possibility of guiding forces reducing and angle of attack minimizing during the movement of a rail vehicle in curved sections of the track with the help of modern control systems. The object is process of rail vehicles movement controlling. It is suggested to use mechatronic control systems for the position of wheel pairs in the horizontal plane for their radial installation in curved track sections for optimal interaction between the railway wheels and rails with achievement of minimum lateral forces and reducing wear.

Effect of impulse loading on cracked beam with L-shaped cross section 冲击荷载对l型截面裂纹梁的影响
Matúš Turis, O. Ivánková
This paper deals with the determination of the dynamic stress intensity factor (DSIF) for two locations of a crack in the beam with L-shaped cross section. The cracks pass through the entire profile body thickness in both position cases.The results shown below were obtained by 3D finite element analysis. Considering only static load (axial tensile) on a beam under given boundary conditions, the SIF for modes II and III was negligible compared to the SIF for mode I. In the case of impulse loading, the mixed mode of loading was introduced due to reflective stress waves.In the first step of analysis, the static SIF was determined for given cracked body geometries. Subsequently, the natural frequencies and their respective ratio of effective to total mass were calculated by modal analysis. After identifying the dominant natural frequency at which the beam oscillates in the direction of the longitudinal axis was done, the duration of time step required for transient analysis was determined.The analysis results are the time record of the SIF for all three loading modes of crack. The results of tensile and compressive impulse forces in the form of half-wave function sine are compared. Overall, six cases are evaluated depending on the position of the crack and the applied external load.This paper deals with the determination of the dynamic stress intensity factor (DSIF) for two locations of a crack in the beam with L-shaped cross section.

Genetically engineered food products threaten human health: A comprehensive research needed 转基因食品对人类健康的威胁:需要全面的研究
Mahrus
The presence of genetically engineered food (GEF) products commonly called genetically changed organism products has the goal to overcome the world food crisis. However, the products being controversy about some countries. They argue that these GEF products can endanger the health of consumers. This paper aims to discuss are GEF products threat human health. GEF products are organisms have undergone genetic modification using DNA recombining or genetic engineering technology. Many foods are genetically chan ged whole foods or contain ingredients derived from gene modification technology. The basic principle of genetic engineering technology is to manipulate the composition of DNA or to insert new genes into the structure of the recipient’s DNA. It means that the scientists inserted genes into the recipient’s living creatures can come from other living things. They still nowadays see those threats as a small trace is not to worry about them. People assumed that GEF products into threats living things, especially human beings. Even though, it is excessive emotional worry according to a scientific point of view because the event is very unlikely occurred. It recognized that any product has certain weaknesses for its advantages. Hence, it suggested that it’s better to be careful with GEF products to be consumed.
基因工程食品(GEF)产品通常被称为转基因生物产品的存在是为了克服世界粮食危机。然而,该产品在一些国家受到争议。他们认为这些GEF产品会危害消费者的健康。本文旨在探讨全球环境融资产品对人体健康的威胁。GEF产品是利用DNA重组或基因工程技术进行基因改造的生物体。许多食物都是经过基因改造的天然食物,或者含有来自基因改造技术的成分。基因工程技术的基本原理是操纵DNA的组成或将新的基因插入受体DNA的结构中。这意味着科学家们将基因插入到接受者的生物体内可以来自其他生物。他们现在仍然把这些威胁看作是一个小痕迹,不用担心。人们认为GEF产品会威胁到生物,尤其是人类。尽管如此,根据科学的观点,这是过度的情绪担忧,因为事件发生的可能性很小。它认识到,任何产品都有其优势的某些弱点。因此,建议最好小心使用GEF产品。

Detection of Candidatus Liberibacter asiaticus in the relatively new area of citrus plantation (Citrus spp.) in the absent of insect vector Diaphorina citri Kuw in Taro Village, Gianyar, Bali, Indonesia 印尼巴厘岛吉安雅芋头村柑桔人工林相对新种(柑桔属)无病媒柑桔地虱(Diaphorina citri Kuw)的检测
I. Wirawan, Putu Alita Dewi, I. Wijaya, Wayan Adiartayasa
Six species of citrus plants visually observe at citrus plantations in Taro Village, Gianyar, Bali, Indonesia. The village is relatively new area for citrus that was previously reported free from citrus disease, citrus vein phloem degeneration (CVPD) or citrus greening or huanglongbing that caused by Candidatus Liberibacter asiaticus. The six citrus plants were Citrus nobilis, C. amblycarpa, C. reticulata, C. aurantifolia, C. limon and C. maxima. Six species of citrus plants found in the area which showed the CVPD like symptom. Samples from these six citrus species were then analyzed by using polymerase chain reaction (PCR) using 16S rDNA fragments as primers (O11 and O12c) to identify the bacteria, L. asiaticus. The result of this study showed that five of six citrus plants in Taro village were positively infected by L. asiaticus. While one species, C. limon, was negatively infected, the result suggested that C. limon may infected by other organisms or caused by other factors. In addition, we did not found any Diaphorina citri Kuw. in the citrus plantation. This result indicated that the citrus plants in Taro village infected by CVPD disease and the disease spread was by seedling which were made through occulation and brought from other area that has been infected by the disease.Six species of citrus plants visually observe at citrus plantations in Taro Village, Gianyar, Bali, Indonesia.

Zainuri, T. Sjah, Nurrachman, C. Ayu
This paper presents the application of the new technology on production of mango fruits at out of its normal seasons, by using growth regulator in North Lombok, as well as presentation of its benefits and potentials for several aspects of mango production, mango producers, and the regions. Source of information for this paper was mainly obtained from authors own research and extension activities related to the introduction of the new technology for production of mango fruits in out of normal mango seasons. The information is also supplemented through reviews of related literatures. The paper concludes that mango off-season technology (MOST) with help from plant growth regulator or hormone, called paclobutrazol, has been recently applied to mangoes in Nusa Tenggara Barat (NTB). The technology is innovative, and adaptive to climate change occurred currently. Despite still not so many growers were convinced to apply for it so far, the technology is friendly to be applied. Its application to mangoes, called here as ‘MOST’ has evidenced that the technology is very useful as it brings many positive impacts. The application is potential to be scaled up to other regions, or to other crops in the same or different regions.This paper presents the application of the new technology on production of mango fruits at out of its normal seasons, by using growth regulator in North Lombok, as well as presentation of its benefits and potentials for several aspects of mango production, mango producers, and the regions.
