  • The field of this study is in Islamic jurisprudence. Taking the preferred saying is contrary to the original, and takes it if necessity or need arises. There are reasons for adopting the preferred saying that were mentioned in this research so that the mufti and jurist know when to take the preferred saying, and when to act with the most correct saying. The origin is the work of the jurist and mufti by saying the most correct. If the necessity or the need that prompted the mufti to take the preferred saying ceases, then he returns to work with the most correct saying, and gives it precedence over the most preferred opinion. The researcher recommends that this topic be given more attention from researchers, and that it is taken care of in jurisprudential developments; So that the embarrassment of the nation is lifted, and the jurists clarify the legal ruling on emerging issues.

  • Objective: This work was conducted to investigate the effects of oxidative stress on meat quality, mitochondrial function, calcium metabolism and ferroptosis of broilers. Methods: In this study, a total of 144 one-day-old male Ross 308 chicks were divided into 3 groups (control group, saline group, and hydrogen peroxide [H2O2] group) with 6 replicates of 8 broilers each. The study lasted for 42 d. The broilers in the saline and H2O2 groups were intraperitoneally injected with 0.75% saline and 10.0% H2O2 on the 16th and 37th day of the experimental period respectively, the injection volumes were 1.0 mL/kg of broiler body weight. On the 42nd day of the experimental period, two chicks were randomly selected from each cage, a total of thirty-six chicks were stunned by electric shock and slaughtered to collect breast muscle samples. Results: The H2O2 exposure reduced pH value, increased drip loss and shear force of breast meat (p<0.05), impaired the ultrastructure and function of mitochondria. The H2O2 exposure damaged the antioxidant system in mitochondria, excessive reactive oxygen species carbonylation modified calcium channels on mitochondria, which impaired the activities of key enzymes on calcium channel, resulted in the increased calcium concentration in cytoplasm and mitochondria (p<0.05). In addition, the H2O2 exposure increased the iron content and lipid peroxidation (p<0.05), which induced ferroptosis. Conclusion: Oxidative stress could impair meat quality by causing mitochondrial dysfunction, resulting in calcium metabolism disorder and ferroptosis.

  • The vibrations and noise origin in electric material is due to several coupled physical phenomena. The revolving electric machine complete modeling is complex; it does not allow simple parametric machine structure studies for various operation modes. This work presents a simple electromagnetic model which makes possible the machine principal parts flow estimation from flux density. Special interest is given in determining Switched Reluctance Machine (S.R.M) radial acceleration in accordance with the current supply. Our focus will be only on the magnetic origin efforts that are dominating in the S.R.M. The efforts calculation versus the current is presented in the case of a machine with a linearized rate. These efforts are considered as a tangential force producing the torque and a radial force that generates no torque. The application is realized on a 6/4 low power S.R.M type (6 stator teeth and 4 teeth rotor). The mechanical response is substituted in a transfer function. The model takes account of the power supply of the machine, the relation between the current supply and the efforts as well as the vibratory response of the machine to these efforts. Finally, the model is validated by comparison with similar experimental results within the framework of the definite assumptions.

  • This study investigated the epidemiology of Listeria (L.) monocytogenes, a food-borne pathogen. The epidemiology of food-borne pathogens is of great importance for clarifying bacterial origin and preventing bacterial contamination and infection. This work examined 68 L. monocytogenes strains, including 11 reference strains and 57 isolates from imported US beef, domestic meats (beef, pork, chicken meat), raw milk, and milk plants. The random amplified polymorphic DNA (RAPD) techniques were optimized to develop a standard molecular epidemiological analysis of L. monocytogenes. There was great genetic variability among the isolates, which produced 24 and 34 RAPD patterns with primer HLWL85 and HLWL74, respectively. The discriminatory power of the RAPD methods with HLWL85 and HLWL74 primer were very high (DI = 0.957; S ${\geq}$ 80%, S ${\geq}$ 95%). Some RAPD types were specific to origin. A few RAPD types were specific for L. monocytogenes strains belonging to a particular serotype. Using the HLWL85 primer, the strains isolated from milk plants could be distinguished from the other strains. And using the HLWL74 primer, the strains isolated from imported beef (US) could be distinguished completely from the other strains.

  • The UNCITRAL, during its thirty-two session in 1999 discussed certain issues and problems identified in interactional commercial arbitration practice. The issues discussed include certain aspects if conciliation proceedings ; the legislative requirement of a written form for the arbitration agreement ; arbitability ; soverign immunity ; consolidation of more than one case into one arbitral proceedings ; confidentiality of information in arbitral proceedings ; rasing claims in arbitral proceedings for the purpose of set-off ; decisions by "turncated" arbitral tribunals liability of arbitrators ; power by the arbitral tribunal to award interest ; costs of arbitral proceedings ; enforceability of interim measures of protection ; and discretion to enforce an award that has been set aside in the state of origin. Among those issues discussed, most of States agreed that the issues relating to certain aspects of conciliation proceedings ; the legislative requirement of a written form for the arbitration agreement ; enforceability of interim measures of protection ; and discretion to enforce an award that has been set aside in the State of origin should have priority over other issues. The UNCITRAL may wish to consider the desirability of preparing uniform provisions on any of those issues, possibly indicating whether further work should be towards a legislative text (such as a model legislative provision or a treaty) or a non-legislative text (such as a model contractual rule).

  • processes at the origin of the star formation in the galaxies over the last 10 billions years. While it was proposed in the past that merging of galaxies has a dominant role to explain the triggering of the star formation in the distant galaxies having high star formation rates. In the opposite, more recent studies revealed scaling laws linking the star formation rate in the galaxies to their stellar mass or their gas mass. The small dispersion of these laws seems to be in contradiction with the idea of powerful stochastic events due to interactions, but rather in agreement with the new vision of galaxy history where the latter are continuously fed by intergalactic gas. I was especially interested in one of this scaling law, the relation between the star formation (SFR) and the stellar mass (M*) of galaxies, commonly called the main sequence of star forming galaxies. I have studied this main sequence, SFR-M*, in function of the morphology and other physical parameters as the radius, the colour, the clumpiness. The goal was to understand the origin of the sequence's dispersion related to the physical processes underlying this sequence in order to identify the main mode of star formation controlling this sequence. This work needed a multi-wavelength approach as well as the use of galaxies profile simulation to distinguish between the different galaxy morphological types implied in the main sequence.

  • Ram pressure due to the intracluster medium (ICM) is known to play a crucial role in removing the cool gas content of a galaxy on a short timescale, potentially driving a star forming galaxy to evolve into a red passive population. Although many HI imaging studies find clear evidence of diffuse atomic gas stripping from cluster galaxies, it is still debatable whether the ram pressure can also strip dense molecular gas. NGC 4522, a Virgo spiral, undergoing strong ram pressure stripping, is one of the few cases where extraplanar CO emission together with stripped HI gas and $H{\alpha}$ knots has been identified, providing an ideal laboratory to study the molecular gas stripping event and the extraplanar star formation activity. The aim of this work is to investigate the origin of extraplanar molecular clouds near NGC 4522 (e.g. stripped or forming in situ), and to probe a relation between the molecular gas surface density and the star formation rate (i.e. the Kennicutt-Schmidt law) at sub-kpc scale, especially in the extraplanar space, using ALMA Cycle 3 CO data and $H{\alpha}$ data of NGC 4522. We present the results from our ALMA observations, and discuss possible scenarios for the origin of extraplanar molecular clouds and to characterize the star formation activity associated with stripped gas outside the galactic disk.

  • The aim of the work described in this paper is to develop a complex underground acoustic system which detects and localizes the origin of an underground hammering sound using an array of hydrophones located about loom underground. Three different methods for the sound localization will be presented, a time-delay method, a power-attenuation method and a hybrid method. In the time-delay method, the cross correlation of the signals received from the array of sensors is used to calculate the time delays between those signals. In the power-attenuation method, the powers of the received signals provide a measure of the distances of the source from the sensors. In the hybrid method, both informations of time-delays and power-ratios are coupled together to produce better performance of position estimation. A new acoustic imaging technique has been developed for improving the hybrid method. This new acoustic imaging method shows the multi-dimensional distribution of the normalized cost function, so as to indicate the trend of the minimizing direction toward the source location. For each method the sound localization is carried out in three dimensions underground. The distance between the true and estimated origins of the source is 28m for a search area of radius 250m.

  • This paper aimed at investigating into the origin and meaning of the Japanese architect Terunobu Fujimori's 'piercing column', and drew a conclusion as follows. First, the piercing column that made its first appearance in his architect debut work Jinchokan Moriya Historical Museum (1991) was conceived unexpectedly from pencil lines on a sketch that went through over the building's roof. And the tree-like natural treatment of the column's surface was influenced by Takamasa Yoshizaka's description of a Mongolian mud-house. Second, most of piercing columns in his later works have nothing to do with a structural role as in Jinchokan, but were designed for a visual effect and as a symbolic gesture. Again, they allude to a tree in nature through a roughly peeling treatment of the surface. Third, considering his ideas in History of Humankind and Architecture (2005), his column could be related to a universal origin of architecture and a symbol of the sun-god faith, and in particular to independent columns of Japanese Shito shrines, such as 'Onbashira' in Suwa and 'Iwanebashira' in Izumo. That is to say, the Fujimori column is a medium that implies the animistic nature-faith of Japan. Nevertheless, Fujimori's naturalism hints at a disquieting quality through an intentional artificiality and a provocative conflict between structure and finish of a building, which might be one aspect of the modern condition, 'uncanny'.

  • The origin of Jindo dogs has been controversial. It has been informed by words of mouth that they are the offsprings of either the digs of Sung dynasty (960~1279 A.D.) in China or the Mongolian dogs. Some breeds of dogs in Japan now have almost same appearance as Jindo dogs. The authors reviewed the history of Japan and found that Korean hunting dogs were sent to Japan in early 5th century, which was before Sung dynasty of China. Dr. Jae-Keun Ryu of National Institute of Environmental Research has done some work on serums of dogs of both Korea and Japan; the results of his serological and molecular biological studies indicated that Korean dogs were sent to Japan 1,300~2,500 years ago. Jindo dogs appear to be the descendants of the dogs of the Stone Age. They have adapted themselves to the unfavorable environment of Jindo island so that they can maintain pure line-age and wild nature until today. It was concluded that they are Korean native dogs, not the offsprings of the dogs of Sung dynasty or the Mongolian dogs.
