A NEW APPROACH TO ESTIMATE KINETIC DECOMPOSITION FROM TG-DTG OR DSC CURVE

This paper reports a new approach to estimate kinetic parameters for the thermal decomposition of the solid state from TG-DTG or DSC curve.Reduced equations are derived for the first tlme.The validity of these equations was demonstrated employing data obtained from the dehydration process of calcium oxalate monohydrate.

A NEW APPROACH TO THE SYNTHESES OF THE PHEROMONES OF JAPANESE BEETLE AND BONTEBOK WITH(Z)-VINYL CUPRATES

The dl-form of the sex pheromone of Japanese b(?)tle and the trail pheromone of Bontebok were synthesised in high purity of (Z)-olefinic configuration. The key step of the syntheses of compounds (1) and (2) involved stereospecific addition of n-alkyl cuprates to acetylene followed by addition of vinyl cuprates to aldehyde (7) and 3-buten--2-one.

The Mixed Spin-1/2 and Spin-1 Ising–Heisenberg Model in the Mean-Field Approximation: a New Approach

Thermodynamic properties of the mixed spin-1 and spin-1/2 Ising-Heisenberg model are studied on a honeycomb lattice using a new approach in the mean-field approximation to analyze the effects of longitudinal Dz and transverse Dx crystal fields. The phase diagrams are calculated in detail by studying the thermal variations of the order parameters, i.e., magnetizations and quadrupole moments, and compared with the literature to assess the reliability of the new approach. It is found that the model yields both second- and first-order phase transitions, and tricritical points. The compensation behavior of the model is also investigated for the sublattice magnetizations, and longitudinal and transverse quadrupolar moments. The latter type of compensation is observed in the literature but its possible importance is overlooked.

Taking a New Approach

THE tiny Chinese village of Wukan in Guangdong Province has gone from obscurity to public prominence in three months. More than 10,000 villagers who call Wukan home embarked on a three-month long confrontation with the local government in September 2011, an event watched closely by the entire country. In the process, much public debate was stirred up, providing food for thought about how the country should be governed, most notably in rural areas.

A New Approach to Database Auto-Design by Logic

The database auto-design is an important problem in database research.In this paper we propose some new ideas and an approach called“logic approach”to implement the database auto-design.Given a relational scheme and a set of the functional dependencies for the relation we can obtain all of the functional dependencies and key for the relation and determine the normal form the relation satisfies.

A NEW APPROACH FOR IMPROVING SPEAKING FLUENCY

The paper presents the reasons why most Chinese non-English major students can not speak English well. Then it offers several solutions to the problem. Three steps in speaking practice are suggested. Using the texts as starters for question and answer practice is an efficient way for speaking practice. On the basis of question-and-answer practice, the students can be led into the practice of describing pictures in pairs. Once paired work is started, the students can move onto text-related paired practice in which there is a lot of negotiation of meaning. In the final step, group work can be used as a means for discussion and problem solving. The students will find it a most encouraging way to practice speaking ability.

Prostate Priorities A new approach to the cancer that 1 in 6 American men will eventually get

除皮肤癌外,前列腺癌是男性最常见的癌症病患。在美国,男性患该病的可能性比女性患乳腺癌的可能性还要高出33%。然而,前列腺癌的治疗在许多方面仍然相对较落后,广为采用的前列腺特异性抗原(PSA)检验也存在严重问题。针对这种状况,美国前列腺癌基金会号召采用新的诊疗手段。

Hyperbaric oxygen therapy as a new treatment approach for Alzheimer's disease

Hyperbaric oxygen therapy as a new treatment approach for Alzheimer’s disease（AD）：Alongside the increase in life expectancy,the prevalence of age-related disorders,such as neurodegenerative diseases,is on the rise.For example,AD,the most common form of dementia in the elderly,accounts for 60–80%of all dementia cases.

DEVELOPING LEARNERS' LANGUAGE AWARENESS: A NEW APPROACH TO LANGUAGE LEARNING AT THE TERTIARY LEVEL

Sample language awareness activities in vocabulary learning LANGUAGE awareness, as an approach, can be applied in all aspects of English language study: phonol-

A NEW SYNTHETIC APPROACH TO PHOSPHONOPEPTIDE WITH PHOSPHONAMIDE MOIETY

A novel tricomponental condensation leading to p-nitrophenyl- ethyl hydrogen substituted benzylphosphonates was described.The use of these compounds for the synthesis of phosphonopeptide with phosphonamide moiety was demonstrated.

Optimization of a Segmented Filter with a New Error Diffusion Approach

The segmented filters, based on spectral cutting, proved their efficiency for the multi-correlation. In this article we propose an optimisation of this cutting according to a new error diffusion method.

A NEW EXPERIMENTAL AND CLINICAL APPROACH OF COMBINING USAGE OF HIGHLY ACTIVE TUMOR-INFILTRATING LYMPHOCYTES AND HIGHLY SENSITIVE ANTITUMOR DRUGS FOR THE ADVANCED MALIGNANT TUMOR

In recent years, tumor-nfiltrating lymphocytes (TILs) have been reported to be effective for tumors in experimental and clinical research. In order to increase the therapeutical effect, we modified some steps of Rosenberg's approach a. cold digestion with collagenase at 4C for 24 hours; b. sedimentation instead of centrifugation; c. elimination of tumor cells before the cultivation procedure. Compared with the original approach, the proliferation, activity and cytotoxicity of TILs obtained by the modified procedure were much improved. TILs' expansion-old was greater than that with the original approach. Cytotoxicity against rumor cells was more potent. Increased TILs' subsets were CD3 and CD8 cells. Meanwhile, we took tumor cells from tumor tissues to test their in vitro chemosensitivities to different drugs in order to select highly sensitive antitumor drugs for treatment of cases with advanced tumors. According to the design of using highly active TILs and highly sensitive drugs (H & H therapy), preliminary clinical results of 50 cases showed higher response rates than those in treatment with TIL / IL2, LAK / 1L2 and TIL+IL2+CTX. Less toxic side effects were observed in 14 patients.
