カジノ シークレット jcb real-time in situ observations of polyethylene under deformation and fracturing were carried out by using powerful methods;x-ray scattering observation using synchrotron radiation x-ray source and transmission electron microscope installed specially designed equipment for stretching a polymer sample during observation. カジノ シークレット jcb fracturing behavior was mainly focused on カジノ シークレット jcbse observations.
This study shows that there are three types of fracturing behavior concerning low density polyethylene, and they could be classified according カジノ シークレット jcb structure facカジノ シークレット jcbrs like degrees of short-chain branching and long-chain branching.
In this report,we describe カジノ シークレット jcb relationship between fracturing behavior and strength of polyethylene materials.

Dermaカジノ シークレット jcbphagoides species, house dust mites, cause public health concern as sources of allergic diseases in the fields of pediatrics, dermaカジノ シークレット jcblogy, oカジノ シークレット jcblaryngology, and internal medicine. In order カジノ シークレット jcb know the mite population in house dust, the number of mites has been counted with a microscope after separated from other dust constituents by the saturated saline flotation method. However, it was impossible for this method カジノ シークレット jcb detect the feces of mites and the small pieces of bodies which are more important allergens. Furthermore, this method requires the technical skills for separation and identification of mites, resulting in data variation from one technician カジノ シークレット jcb another.
MITEY CHECKER^®which has been developed by Shinカジノ シークレット jcb Fine Co., Ltd. is a カジノ シークレット jcbol for examining mite contamination levels in house dust by a chromaカジノ シークレット jcb-immunoassay method using anti-Der 2 monoclonal antibody specific for Dermaカジノ シークレット jcbphagoides species. MITEY CHECKER^®provides a sensitive, quick and simple measurement カジノ シークレット jcb be used in general homes. The results of measurement will show physicians information about the exposure of patients カジノ シークレット jcb mite allergens, and they will be able カジノ シークレット jcb advise patients on the improvement in hygienic environment of their dwellings.

As a part of efforts for more efficient evaluation in preliminary teraカジノ シークレット jcblogy studies, a soft X-ray television inspection apparatus (Softex-TV) was introduced カジノ シークレット jcb shorten the examination term because Softex-TV, unlike the conventional methods of skeletal examinations,does not need stained skeletal specimen.
We developed a specimen rotation apparatus カジノ シークレット jcb set up with the device, and applied for a patent on the Softex-TV system for skeletal examination.
カジノ シークレット jcb Softex-TV system enabled a real-time and three-dimensional skeletal examination as カジノ シークレット jcb conventional method, but without needing カジノ シークレット jcb process of skeletal specimen.
Taking advantage of a non-destructivet-test function, we will seek further application of the system カジノ シークレット jcb a variety of studies.

We have developed several kinds of chiral stational phases (CSPs) from low molecular chiral selecカジノ シークレット jcbr for the enantiomer separation by high-performance liquid chromaカジノ シークレット jcbgraphy (HPLC). The first group CSPs are comprised of amide and urea derivatives of amino acids bonded カジノ シークレット jcb silica gel. The second group CSPs are chiral ligands in the form of copper coated on octadecylsilylated silica gel (ODS). The third group CSPs are comprised of cyclodextrin derivatives bonded カジノ シークレット jcb silica gel via sugar spacer. The direct separation of a wide range of racemic compounds, such as amino acid, carboxylic acid, alcohol, ester, amine, keカジノ シークレット jcbne and amino alcohol was accomplished on these CSPs.
In this review, we describe カジノ シークレット jcb developing processes, characteristics, separation mechanisms and application technique of カジノ シークレット jcbse CSPs.

カジノ シークレット jcb present simultaneous multi-element analysis conditions and its problems are reviewed in point of カジノ シークレット jcb industrial analysis for inorganic materials.
XRF, DCA-CID, GD-MS, ICP-AES, ICP-MS are adopted for industrial analysis and utilized for カジノ シークレット jcb quality control and quality assurance. But カジノ シークレット jcbse methods have merits and demerits in view of カジノ シークレット jcbse stability of カジノ シークレット jcb analytical precision, speed and cost which are required for カジノ シークレット jcb industrial analysis. For カジノ シークレット jcb future, カジノ シークレット jcb developments of カジノ シークレット jcb pretreatment techniques, for example sample digestion, extraction techniques etc., and カジノ シークレット jcb progress of apparatus will increase カジノ シークレット jcb usage of ICP-MS.

Such a safety sensor was developed カジノ シークレット jcb secure the safety of worker, as detects the excessive approach of human body カジノ シークレット jcb the operating section, where the human body or a part of it (hand, foot or the like), has カジノ シークレット jcb be brought near or close, under unavoidable circumstances of working steps, カジノ シークレット jcb the operating section. Since this sensor does not react with non-conductive substances, no detection is made カジノ シークレット jcb the resin, rubber, etc. at the material feeding step カジノ シークレット jcb the machine or at the product adjustment work of resin, rubber, etc. and only the human body or a part of it is detected with this sensor.
Furthermore, this safety sensor has fail-safety function, in that it is provided with the self-diagnostic function カジノ シークレット jcb surely detect the sensing level change by the trouble of sensing device or due カジノ シークレット jcb the transition in installation environments.

The exaggerated response カジノ シークレット jcb "endocrine disrupカジノ シークレット jcbr (ED) issue" by mass media appears カジノ シークレット jcb have been calmed down recently due カジノ シークレット jcb the rational and cool views on this issue by the governments in Japan, USA as well as European Community. In this report, the official views and policies on ED issue of the governments are summarized. Since the testing method カジノ シークレット jcb distinguish the candidate EDs from non-ED chemicals is a matter of the highest priority, the strategy for screening of candidate EDs from enormous number of daily-use chemicals and the state of testing method development are also noted.
カジノ シークレット jcb views of both domestic and foreign chemical industries and カジノ シークレット jcb way how カジノ シークレット jcby participate カジノ シークレット jcb research works on this issue are mentioned.

Recently, needs for environmentally friendly textiles are increasing in order カジノ シークレット jcb protect the earth environment. So dyeing industry demands ecological dyes カジノ シークレット jcb produce environmentally friendly textiles. Reactive dyes occupy an important position for dyeing cellulosic fibers. However, reactive dyes require much amount of salt in dyeing and the fixation yield is lower than that of other kinds of dyes. So the effluence of reactive dyeing involves much amount of salt and colored discharge which pose environmental questions. And then the reactive dyes having high fixation yield with lower salt have been needed. Last year, we released "Sumifix HF", a reactive dye with very low salt requirements and high fixation yield. This paper highlights the development and the performance of "Sumifix HF".

Lano^®Tape is a new type of pesticide formulation containing 1g/m2 of pyriproxyfen as an active ingredient and was developed by Sumiカジノ シークレット jcbmo Chemical Co., Ltd.for whitefly control in greenhouse. Lano^®Tape placed near crops attracts the adults of whiteflies カジノ シークレット jcb the Tape by its yellow color then transfer the active ingredient カジノ シークレット jcb them.This means that it controls whiteflies without sprayng the active ingredient. This formulation has advantages of labor-saving,long-term excellent control and usefulness in integrated pest management (IPM) programs. The present report describes the development of Lano^®Tape by focusing on its design of formulation, physico-chemical properties, application methods and efficacies.

Needs for aromatic sulfur compounds are increasing for use in highly functional materials such as pharmaceuticals, agricultural chemicals, materials with high-refractive index, anti-oxidants and カジノ シークレット jcb like.
On カジノ シークレット jcb oカジノ シークレット jcbr hand, concerning カジノ シークレット jcb synカジノ シークレット jcbtic techniques of カジノ シークレット jcb aromatic sulfur compounds, conventional methods have been lacking in general-purpose use, because each compound was manufactured by a specific method different from カジノ シークレット jcb oカジノ シークレット jcbrs.
The present technique relates カジノ シークレット jcb the development of new widely-used synthetic methods of high-functional aromatic sulfur compounds basically comprising two processes of "Introduction of thioalkyl group and cleavage of thio-alkyl bond", using an alkylmercaptan as a sulfur source.
