Objective: This study was conducted to investigate the effect of fermented cottonseed meal (FCSM) on growth performance, carcass traits, and fat deposition in white-feather broiler chickens. Methods: A total of 480 male one-day-old white-feather broiler chickens were selected randomly and divided into four groups with six replicates of 20 chickens in each. The experimental chickens were fed diets including 3%, 6%, or 9% FCSM fermented by Candida tropicalis until 42 days old. In the experiment, the chickens of the control group were fed soybean meal. Results: FCSM supplementation linearly decreased the feed conversion ratio from d 15 to 21 and d 36 to 42, respectively (p<0.05). The percentage of carcass and semi-eviscerate increased in response to dietary FCSM supplementation at d 21 (p<0.05). The percentage of eviscerated and semi-eviscerate of 3FCSM was higher than that in other groups at d 35 (p<0.05). At the age of 42 d, the percentage of carcass increased in a quadratic way among increasing FCSM in diets (p<0.05). The subcutaneous fat thickness linearly decreased with the increasing levels of FCSM at d 21 (p<0.05). Gompertz and Logistic functions provided a better fit on abdominal fat and subcutaneous fat, respectively. The best fitted equation predicted that the maximum growth rate of abdominal fat weight and subcutaneous fat thickness occurred at d 28. FCSM had no significant effects on the shape of growth curve of abdominal fat weight and subcutaneous fat thickness, but reduced the height of the curve. Birds receiving the 6FCSM diet for 21 d had smaller adipocyte surface and lower serum glucose as well as triglyceride concentration. Conclusion: FCSM is beneficial for broiler chickens as it positively affects their growth and carcass in addition to altering their fat deposition.

Superconducting fault current limiter (SFCL) is a kind of short-circuit current limiting device for power grid. It's a new application of superconducting technology on power equipments. Saturated Iron-core Superconducting fault current limiter (SISFCL) is one of many types of SFCL. It takes the advantage that no quenching occurs in superconducting wires during fault current limiting process. The immediately reacting and fast recovering are also its main characteristics. The structure and function of SISFCL is similar to that of traditional transformer and current limiting reactor respectively. Based on mature technologies on design and manufacture of iron core and windings of transformers, SISFCL could be made at the same voltage level as traditional transformers. But there are also significant differences between them. SISFCL will offer an effective solution to limit short-circuit current in future HV or EHV power systems because of its peculiar structures and properties. In this paper, we introduce the structure and characteristics of the SISFCL developed by Innopower. It may help readers to understand SISFCL and its enormous application value for power grids.

Background: Breast cancer is one of the most common cancers in women in the world. Health-related quality of life (HRQL) at treatment endpoint in cancer clinical trials is widely considered to be increasingly important. The aim of this review was to provide a literature-based assessment of the validity, reliability and responsiveness of breast cancer-specific HRQL instruments in women breast cancer patients. Materials and Methods: The databases consulted were Medline, PubMed, and Embase. The inclusion criteria required studies to: (1) involve use of HRQL measures; (2) cover women with breast cancer under standard treatment (surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy); (3) involve the validity, reliability, or responsiveness of HRQL; (4) deal with validation of breast cancer-specific HRQL instruments. Results: A total of 16 studies were identified through the literature search that met the 4 inclusion criteria. Some seven instruments were assessed among these 16 studies: EORTC QLQ-BR23, FACT-B, FACT-ES, HFRDIS, LSQ-32, QLICP-BR, and SLDS-BC. EORTC QLQ-BR23, FACT-B, LSQ-32, QLICP-BR, and SLDS-BC are more general breast cancer-specific HRQL instruments. FACT-EB is the endocrine subscale combined with FACT-B in order to measure the side effects and putative benefits of hormonal treatment administered in breast cancer patients. HFRDIS is the HRQL measure focusing on hot flash concerns. Conclusions: This paper provides an overall understanding on the currently available breast cancer-specific HRQL instruments in women breast cancer patients.

The pure product of 2,3-diaminophenazine was prepared by the enzyme-catalyzed reaction of ophenylenediamine-$H_2O_2$-horseradish peroxidase and characterized by UV/Vis spectroscopy, IR spectroscopy and NMR spectroscopy. The electrochemical behaviour of 2,3-diaminophenazine on the glassy carbon electrode was studied. The interaction between 2,3-diaminophenazine and deoxyribonucleic acid was studied by cyclic voltammetry method and UV/Vis spectroscopy, which indicated that the interaction between them is intercalation. The influence of reacting time was also studied. The binding ratio of the 2,3-diaminophenazine-DNA complex is calculated to be 1 : 2 and the binding constant is to be $5.07{\times} 10^3L{\cdot}mol^{-1}$ at room temperature.

The Taliban Factor in the Republic of Korea`s Afghanistan Strategy
( Niu Song ) 한국국방연구원 2013 The Korean Journal of Defense Analysis Vol.25 No.1
Years of hiding of the Taliban and its comeback in 2006 forms a potential and real challenge to the Republic of Korea`s Afghanistan Strategy. Based on different standpoints, the Republic of Korea (ROK) and the Taliban both have different recognitions of the main contradictions in the three stages between each other. The first stage (2002.July2007), contradictions of anti-terrorism and terrorism activities and reconstruction and anti-reconstruction activities (ROK`s view) and anti-invasion and invasion (Taliban`s view); the second stage (July 2007. end of2009), contradictions of safeguarding and abusing of human rights (ROK) and defending and opposing Islam (Taliban); Third stage (end of 2009 to present),contradictions of assuming and opposing its responsibility to its allies and the international community (ROK) and maintaining and disdaining Pashtu tribal honors (Taliban). While there are complicated contradictions between the ROK and the Taliban and no great progress in the U.S. Afghanistan strategy, it is very hard for ROK to put its Afghanistan strategy into further practice.

Technique for Intrusion Detection based on Minkowsky Distance Negative Selection Algorithm
Niu Ling,Feng Gao-feng,Peng Hai-yun 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.12
Traditional negative selection algorithms often result in a number of black holes, which directly leads to the missing alarm drawback in the intrusion detection system. In order to settle the above problem, a novel negative selection algorithm based on Minkowsky distance is proposed. Firstly, the proposed algorithm computes the Minkowsky distance between the detectors. Then, compute the serial same numbers between the detector and self-set strings, which is helpful to improve the coverage area of the detector. Finally, the new detectors after training and renewal are put into the mature detector set to decline the number of black holes. Experimental results demonstrate that, compared with the traditional negative selection algorithms, the number of black holes and the missing alarm rate decline a lot in the proposed algorithm.

<P><B>Abstract</B></P> <P>A 12-week feeding trial was conducted to evaluate the effects of multi-strain probiotics (MSP) in a low fish meal (FM) diet on overall performance, gut microbiota, selected non-specific immune responses and antioxidant enzyme activities of olive flounder (<I>Paralichthys olivaceus</I>) juveniles. A total of 225 healthy olive flounders (initial mean body weight, 13.5 ± 0.01 g) were randomly separated into 3 groups of 75 fish, each group having three replicates of 25 fish; first group was fed with a FM-based control diet (Con), 2nd group was fed with a low-FM diet containing a blend of plant and animal protein meals replacing 30% of the FM protein (FM30), and 3rd group was fed with the FM30 diet supplemented with 10<SUP>8</SUP>–10<SUP>9</SUP> CFU kg<SUP>−1</SUP> of the MSP (Pro). With the exception of lipid retention, which was significantly lower in fish fed the FM30 diet compared to the other two treatments, no other statistically significant differences were recorded with respect to any of the other growth and nutrient utilization parameters. Myeloperoxidase and lysozyme activities of fish fed the Pro diet were much higher and significantly different than those of fish fed the FM30 diet. Glutathione peroxidase activity was significantly higher in Pro- than in Con-fed fish, which, in turn, was significantly higher than FM30-fed fish. Expression of immune-related genes including IL-1β, IL-6, and TNF-α was markedly upregulated in livers of the fish fed Pro diet compared to those fed the Con and FM30 diets. Furthermore, supplementation of MSP in FM30 diet enriched the <I>Lactobacillus</I> abundance in the fish gut as well as predictive gene functions in relation to lipid and carbohydrate metabolisms. These data suggested that the MSP could reduce the potential adverse effects of the low-FM diet and might be used as a healthy immunostimulant for olive flounder.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Low fishmeal diet (FM30) significantly affected the lipid retention of olive flounder. </LI> <LI> The multi-strain probiotics (MSP) improved the activities of myeloperoxidase, lysozyme, and glutathione peroxidase. </LI> <LI> The MSP supplement markedly upregulated the immune-related gene expression of IL-1β, IL-6, and TNF-α in the liver. </LI> <LI> The MSP supplement enriched the predictive gene functions in relation to lipid and carbohydrate metabolisms. </LI> <LI> The MSP could be used as a healthy immunostimulant for olive flounder. </LI> </UL> </P>
