论罪犯的可改性与难改性

看待罪犯要坚持可改性与难改性的两点论，既要看到罪犯的可改性，又要看到罪犯的难改性。在可改性与难改性中要坚持重点论，就罪犯来讲，难改性是其主导方面；就可改性来讲，改造机制的作用力是其主导方面。只有正确看待罪犯的可改性，才能提高干警的责任感、主动性、创造性。只有充分估计罪犯的难改性，才能对罪犯的反社会性保持清醒的认识，着力抓好立场观点的转变；才能对罪犯的反抗保持应有的警惕，牢牢掌握改造的主控权；才能对罪犯改造的长期性和艰巨性有充分的思想准备，坚持不懈地实现预定目的。

Biocorrosion property and cytocompatibility of calcium phosphate coated Mg alloy

Calcium phosphate coated Mg alloy was prepared. The phase constitute and surface morphology were identified and observed by X-ray diffractometer （XRD） and SEM. The results show that the coating is composed of flake-like CaHPO4-2H2O crystals. The corrosion resistance of the coated Mg alloy was measured by electrochemical polarization and immersion test in comparison with uncoated Mg alloy. Cytocompatibility was designed by observing the attachment, growth and proliferation of L929 cell on both coated and uncoated Mg alloy samples. The results display that the corrosion resistance of the coated Mg alloy is better than that of uncoated one. The immersion test also shows that the calcium phosphate coating can mitigate the corrosion of Mg alloy substrate, and tends to transform into hydroxyapatite （HA）. Compared with uncoated Mg alloy, L929 cells exhibit good adherence, growth and proliferation characteristics on the coated Mg alloy, indicating that the cytocompatibility is significantly improved with the calcium phosphate coating.

Parikh-Wilczek Tunneling as Massive Particles from Noncommutative Schwarzschild Black Hole

In this paper, we apply the tunneling of massive particle through the quantum horizon of a Schwarzschild black hole in noncommutative spaeetime. The tunneling effects lead to modified Hawking radiation due to inclusion of back-reaction effects. Our calculations show also that noncommutativity effects cause the further modifications to the thermodynamical relations in black hole. We calculate the emission rate of the massive particles＇ tunneling from a Schwarzschild black hole which is modified on account of noncommutativity influences. The issues of information loss and possible correlations between emitted particles are discussed. Unfortunately even by considering noneommutativity view point, there is no correlation between different modes of evaporation at least at late-time. Nevertheless, as a result of spacetime noncommutativity, information may be conserved by a stable black hole remnant.

Component-based software reliability analysis incorporating imperfect debugging and change-point

Against the deficiencies of component-based software(CBS) reliability modeling and analysis,for instance,importing too many assumptions,paying less attention to debugging process without considering imperfect debugging and change-point(CP) problems adequately,an approach of CBS reliability process analysis is proposed which incorporates the imperfect debugging and CP.First,perfect/imperfect debugging and CP are reviewed.Based on the queuing theory,a multi-queue multichannel and infinite server queuing model(MMISQM) is presented to sketch the integration test process of CBS.Meanwhile,considering the effects of imperfect debugging and CP,expressions for fault detection and correction are derived based on MMISQM.Numerical results demonstrate that the proposed model can sketch the integration test process of CBS with preferable performance which outperforms other models.

SWELLING AND WETTABILITY OF LIGHT-CURED METHACRYLATE-BASED DENTAL RESINS PREPARED FROM CHOLIC ACID

2＇-methacryloxy-3α, 7α, I2α- trimethacryloyl cholic acid ethyl ester （CAGE4MA） has been prepared from cholic acid. Photo-polymeric resins were prepared from CAGE4MA. 2,2-bis[4-（2-hydroxy-3-methacrylyloxypropoxy）phenyllpropane （bis-GMA） was used for comparison, triethyleneglycol dimethacrylate （TEGDMA） was used as diluent. The polymerization was initiated by camphoroquinone （CQ）/N, N-dimethylaminoethyl methacrylate （DMAEMA） system. The conversion of CAGE4MA was 39% when the reaction time is 60s, which is lower than bis-GMA and TEGDMA. The swelling value of CAGE4MA resin was 0.41% in distilled water, which is much lower than those of bis-GMA resin （2.04%） and TEGDMA resin （4.77%） under the same conditions. Copolymers from CAGE4MA and TEGDMA have been prepared. With the increase of TEGDMA in mixture, the degree of conversion of CA GE4MA and swelling value increased. The swelling values of photocured resins in 0.1mol/L HCl were also measured.

Morphological Characterization of Mango （Mangifera indica） Accessions Based on Brazilian Adapted Descriptors

The aim of this study was to characterize 103 mango accessions of the field germplasm collection of Embrapa semi-arid region, located in Juazeiro, Bahia, Brazil and to apply 50 morphological descriptors established by the Brazilian Ministry of Agriculture, livestock and supply to help in the development of new mango cultivars for the Northeastern region of Brazil. Four trees were selected for each accession and eight adult leaves, eight flowers and 16 fruits were collected from each tree. Morphological characteristics ranging from plant size to seed embryo were evaluated. Simple percentages were estimated for all the descriptors. Only the descriptors for leaf symmetry and fruit waxiness did not show variability among the accessions. Eight accessions did not show fruits with fibers, while nine other accessions presented flesh firmness, which is an important characteristic to improve breeding. The soluble solids content was high, above 14 ~Brix for 95% of the accessions with Tommy Atkins showing the lowest value, 12.5 ~Brix. A great diversity was found in the color of the epidermis ranging from green to red. The accessions Amrapali and Salitre presented a dark orange flesh color. The obtained data set, are the most comprehensive so far in Brazil, it allows choosing the best parents to develop new cultivars and will also contribute to the protection of mango cultivars in Brazil.

Cross-cultural adaption and psychometric properties of the Chinese version of the Diabetes Behavior Rating Scale: a pilot study

Self-care behavior plays a major role in diabetic management. However, in China, a satisfactory instrument has not yet been developed to evaluate the compliance of self-care behavior for young patients with type 1 diabetes mellitus （T 1DM）. The Diabetes Behavior Rating Scale （DBRS） has a potential to be the first mature instrument. The purpose of this study is to cross-culturally adapt the DBRS, and preliminarily evaluate its psychometric properties. The instrument translation included translation, back translation and culture adaptation. Psychometric properties were assessed in a sample of 116 young patients with T1DM adapting insulin injection therapy. The Chinese version of the DBRS was divided to four subscales. Cronbaeh＇s α for the total scale was 0.92. The mean inter-item and item-total correlations were 0.35 and 0.54 respectively. Test-retest reliability showed good temporal stability （r=0.81, P=0.001）. Negative correlations were found between DBRS scores with the Diabetes Distress Scale scores （r=-0.32, P=-0.003） and hemoglobin Ale （HbAlc） levels （r=-0.36, P=0.002）. Higher DBRS scores correlated with better glycemic control. The Chinese insulin injection therapy version of the DBRS is well translated and culturally adapted. It shows good overall reliability and validity and appears to be a valuable tool for assessing the diabetic self-care behaviors for young patients with T 1DM.

Ionic liquids: Efficient solvent and medium for the transformation of renewable lignocellulose

Carbon-enriched lignocelluloses are regarded as the perfect alternative for nonrenewable fossil fuel, and have a great potential to alleviate the increasing energy crisis and climate change. However, the tightly covalent structure and strong intra and in- ter-molecular hydrogen bonding in lignoceUulose make it high recalcitrance to transformation due to the poor solubility in wa- ter or common organic solvents. Dissolution and transformation of lignocellulose and its constituents in ionic liquids have therefore attracted much attention recently due to the tunable physical-chemical properties. Here, ionic liquids with excellent dissolving capability for biomass and its ingredients were examined. The technologies for lignocellulose biorefining in the presence of ionic liquid solvents or catalysts were also summarized. Some pertinent suggestions for the future catalytic conver- sion and unitization of this sustained carbon-rich resource are proposed.

Integrable discretization of soliton equations via bilinear method and Backlund transformation

We present a systematic procedure to derive discrete analogues of integrable PDEs via Hirota’s bilinear method.This approach is mainly based on the compatibility between an integrable system and its B¨acklund transformation.We apply this procedure to several equations,including the extended Korteweg-deVries(Kd V)equation,the extended Kadomtsev-Petviashvili(KP)equation,the extended Boussinesq equation,the extended Sawada-Kotera(SK)equation and the extended Ito equation,and obtain their associated semidiscrete analogues.In the continuum limit,these differential-difference systems converge to their corresponding smooth equations.For these new integrable systems,their B¨acklund transformations and Lax pairs are derived.
