A comparison study was conducted on viscosity and heat transfer property of the traditional fluorine-bearing(F-bearing)mold flux and the newly designed fluorine-free(F-free)mold flux for casting silicon steel.The results showed that the viscosity of F-free mold flux is lower than that of F-bearing mold flux,as the apparent activation energy of F-free mold flux is also lower than that of F-bearing mold flux confirmed by the kinetics results for viscous flow,which meant that the energy barrier of F-free mold flux that the migration of ion clusters needs to overcome is smaller,and thus leads to a lower viscosity of F-free mold flux.Besides,the research results of the heat transfer suggested that the comprehensive heat transfer coefficient of F-free mold flux is lower than that of F-bearing mold flux in all directions.One reason is that the true density of F-free mold flux increases from glassy state to crystalline state,while that of F-bearing mold flux is opposite.Another reason is that the air gap gets increased due to the volume shrinkage of F-free mold flux from glassy state to crystalline state and the solidification of the molten steel.These introduce a larger thermal resistance of F-free mold flux than that of F-bearing mold flux.Through the comparison,the designed F-free mold flux shows a better lubrication and capacity to control the heat transfer than the traditional F-bearing mold flux. 展开更多

True ternary fission and Tin-accompanied ternary fission of 242Pu are studied by using the'Three Cluster Model'.True ternary fission is considered as a formation of heavy fragments in the region 28≤Z1,Z2,Z3≤38 with comparable masses.The possible fission channels are predicted by the potential-energy calculations.Interaction potentials,Q-values and relative yields for all possible fragmentations in equatorial and collinear configurations are calculated and compared.It is found that ternary fission with formation of a double magic nucleus like 132Sn is more probable than the other fragmentations.Also,the kinetic energies of the fragments for the group Z1=32,Z2=32 and Z3=30 are calculated for all combinations in the collinear geometry as a sequential decay. 展开更多

The paper looks at the issue of the relationship between Marx and Marxism.Three approaches to the issue,which are widespread in contemporary Marxist literature and among marxologists are discussed.The first approach: the true Marx is the philosophy of Marx minus political theory.The second approach: the true Marx is the philosophy of Marx plus political theory of social-democratic parties.The third approach: the true Marx is the philosophy of Marx plus political theory,developed most fully by Lenin in the preparation of the Russian revolution.The third approach,from our point of view,corresponds most to the essence of genuine Marxism,at least as applied to the twentieth century.The paper examines in detail the principal novelty of Lenin speaking of the need to translate Marx’s mat erialistic theory of history to the political level as a theoretical issue.The author also notes the contribution of the Chinese leaders into further development of the political theory of Marxism closely connected with the issues of strategy and tactics of building socialism with Chinese characteristics.In conclusion,the paper states that world history now becomes increasingly complex and mixed.Therefore,the question of whether Marxist philosophers in this situation will be able to find ways of realization the 11th thesis of Marx “On Feuerbach” remains open. 展开更多

The optimization of dietary phosphorus(P) depends on precise details of the P availability in feed ingredients to avoid excess or deficient P in a mixed diet. This study was carried out to measure the apparent ileal digestibility of P for corn, wheat, soybean meal, and corn gluten meal in growing Japanese quails from 28 to 32 d posthatch, A total of 400 quail chicks were randomly distributed across 5 treatments with 4 replicates and 20 birds in each floor pen. The P-free diet(PFD) was formulated based on cornstarch to measure the basal endogenous P losses(EPL). Digestibility coefficients were determined by ileal digesta sampling using TiO2 as an indigestible marker. The EPL was estimated at 384 mg/kg DMI. The apparent ileal P digestibility(AIPD) for corn, soybean meal, wheat, and corn gluten meal were determined to be 0.38.0.53, 0.38, and 0.78, respectively. The corresponding values for true ileal P digestibility(TIPD) were 0.48.0.61, 0.50, and 0.83, respectively. The t-test analysis showed that the difference of AIPD and TIPD values for corn(P = 0.031) and wheat(P = 0.015) were statistically significant, however, no significant differences were observed for corn gluten meal(P = 0.318) and soybean meal(P = 0.104). In conclusion, the correction of AIPD coefficients for EPL in low-P ingredients such as corn and wheat may be much more important than that in high-P feedstuffs such as corn gluten meal and soybean meal in growing quails. 展开更多

AIM: To examine the effects of one-handed phacoemulsification with steep-axis incision on corneal curvature and analyze surgically induced astigmatism(SIA) on the true net power, anterior and posterior corneal surfaces. METHODS: Patients with cataracts underwent onehanded phacoemulsification with a 2.4-mm steep-axis of clear corneal incision(CCI) based on true net power. CCI was created under the guidance of Verion. Central corneal thickness(CCT), keratometry readings of the true net power and anterior and posterior corneal surface were obtained using Pentacam. Biometry, such as axial length, anterior chamber depth(ACD) and white-to-white(WTW) were performed using Lenstar pre-and 3 mo postoperatively. RESULTS: The study evaluated 68 eyes of 65 patients. The mean age was 65.93±9.40 y;CCT was 529.21±37.40 μm;WTW was 11.59±0.35 mm. Regarding true net power, keratometric value at the flattest corneal meridian for the 3-mm central zone(Ks) was significantly decreased postoperatively(P=0.031). Keratometric value at the steepest corneal meridian for the 3-mm central zone(Kf) was increased postoperatively(P>0.05). Astigmatism of true net power was 1.21±0.56 D preoperatively and significantly decreased to 1.02±0.58 D postoperatively(P=0.021). On the anterior corneal surface, no significant difference in Ks and Kf was noted pre-versus postoperatively. Anterior corneal astigmatism was 1.08±0.51 D preoperativelyand significantly decreased to 0.87±0.46 D postoperatively(P=0.002). On the posterior corneal surface, Ks and Kf were significantly increased postoperatively(all P<0.05), and posterior corneal astigmatism also increased(P=0.008). The SIA values of true net power and the anterior and posterior corneal surfaces at 3 mo postoperatively were 1.26±0.63 D(range: 0.11 to 2.80 D), 1.05±0.54 D(range: 0.23 to 2.40 D), and 0.21±0.17 D(range: 0.01 to 0.07 D), respectively. CONCLUSION: One-handed phacoemulsification with steep-axis incision can effectively decrease astigmatism of true net power and anterior corneal asti 展开更多

We read with great interest the recent review of benign epilepsy with centro-temporal spikes (BECTS) and child-hood absence epilepsy (CAE) by Verrotti et al. (1)BECTS and CAE are the most common epilepsy syndromes in childhood and share certain clinical features: similar age at onset, overall good prognosis, and genetic predispo-sition. Several studies have reported the coexistence of the two syndromes, and recently, Verrotti et al. analyzed 19 cases reported to have clinical features of CAE and BECTS. Among the total 19 cases, three cases had fea-tures of both syndromes contemporarily;three cases expe-rienced absence seizures initially followed by BECTS;and the other 13 cases experienced BECTS at onset and had absence seizures later. 展开更多

A gallbladder polyp is an elevation of the gallbladder mucosa that protrudes into the gallbladder lumen.Gallbladder polyps have an estimated prevalence in adults of between 0.3%-12.3%.However,only 5%of polyps are considered to be“true”gallbladder polyps,meaning that they are malignant or have malignant potential.The main radiological modality used for diagnosing and surveilling gallbladder polyps is transabdominal ultrasonography.However,evidence shows that other modalities such as endoscopic ultrasound may improve diagnostic accuracy.These are discussed in turn during the course of this review.Current guidelines recommend cholecystectomy for gallbladder polyps sized 10 mm and greater,although this threshold is lowered when other risk factors are identified.The evidence behind this practice is relatively low quality.This review identifies current gaps in the available evidence and highlights the necessity for further research to enable better decision making regarding which patients should undergo cholecystectomy,and/or radiological follow-up. 展开更多

A new type of superconductive true random number generator (TRNG) based on a negative-inductance supercon-ducting quantum interference device (nSQUID) is proposed. The entropy harnessed to generate random numberscomes from the phenomenon of symmetry breaking in the nSQUID. The experimental circuit is fabricated by theNb-based lift-off process. Low-temperature tests of the circuit verify the basic function of the proposed TRNG.The frequency characteristics of the TRNG have been analyzed by simulation. The generation rate of randomnumbers is expected to achieve hundreds of megahertz to tens of gigahertz. 展开更多
