仁者乐山,智者乐水。鸟语花香,草木呢喃,那是自然的语言,仔细倾听,你会听到不一样的声音。而这期三位摄影师就为我们带来了自然的谆谆教导,在春来之际,听自然说了什么。当人类欢呼对自然的胜利之时,也就是自然对人类惩罚的开始。——黑格尔一切艺术、宗教都不过是自然的附属物。——亚里士多德心灵与自然相结合才能产生智慧,才能产生想象力。

The U.S. military has a need for more powerful propellants with balanced/stoichiometric amounts of fuel and oxidants. However, balanced and more powerful propellants lead to accelerated gun barrel erosion and markedly shortened useful barrel life. Boron nitride(BN) is an interesting potential additive for propellants that could reduce gun wear effects in advanced propellants(US patent pending 2015-026P). Hexagonal boron nitride is a good lubricant that can provide wear resistance and lower flame temperatures for gun barrels. Further, boron can dope steel, which drastically improves its strength and wear resistance, and can block the formation of softer carbides. A scalable synthesis method for producing boron nitride nano-particles that can be readily dispersed into propellants has been developed. Even dispersion of the nano-particles in a double-base propellant has been demonstrated using a solvent-based processing approach. Stability of a composite propellant with the BN additive was verified. In this paper, results from propellant testing of boron nitride nano-composite propellants are presented, including closed bomb and wear and erosion testing. Detailed characterization of the erosion tester substrates before and after firing was obtained by electron microscopy,inductively coupled plasma and x-ray photoelectron spectroscopy. This promising boron nitride additive shows the ability to improve gun wear and erosion resistance without any destabilizing effects to the propellant. Potential applications could include less erosive propellants in propellant ammunition for large, medium and small diameter fire arms.

The prediction of molecular properties is a crucial task in the field of drug *** methods that can accurately predict molecular properties can significantly accelerate the drug discovery process and reduce the cost of drug *** recent years,iterative updates in computing hardware and the rise of deep learning have created a new and effective path for molecular property *** learning methods can leverage the vast amount of data accumulated over the years in drug discovery and do not require complex feature *** this review,we summarize molecular representations and commonly used datasets in molecular property prediction models and present advanced deep learning methods for molecular property prediction,including state-of-the-art deep learning networks such as graph neural networks and Transformer-based models,as well as state-of-the-art deep learning strategies such as 3D pre-train,contrastive learning,multi-task learning,transfer learning,and *** also point out some critical issues such as lack of datasets,low information utilization,and lack of specificity for diseases.

History Research 2013年第5期3卷 321-341页

作者： Douglas henry Daniels University of California Santa Barbara USA

This essay suggests that in 1962-1963, before Birmingham and the March on Washington, a coalition of Black and White civil rights activists, labor, and religious leaders were in the vanguard of the struggle both on the Pacific Slope and in the nation. Berkeley＇s battle for fair housing represented an important phase of the civil rights struggle on the west coast and in cities where racial segregation was not based on law, but part of a conspiracy, silent but quite effective, among realtors, mortgage lenders, and renters, against Blacks and other minorities. Encouraged by state antidiscrimination legislation, Berkeley activists embarked upon a fair housing campaign based on surveys of the problem, efforts to enact legislation, and direct action. The irrationality of racists who defended their right to discriminate was one of the most singular aspects of the fair housing struggle. Though they lost at the local level, the coalition of new political forces succeeded a few months later at the state level and represented an effective force in liberal politics in the city for years to come. Because of the stiff opposition and the limits of reformers＇ liberal fair housing regulations, however, working class and poor African Americans still faced severe housing problems.

[目的]探讨Suture Button装置治疗下胫腓联合损伤后的手术方法及临床效果。[方法]对截止于2007年9月利用Suture Button装置固定的下胫腓联合急、慢性损伤的13例病人进行连续随访观察,通过术后X线片数字化测量和标准的踝足功能评分,评估其疗效并探讨临床应用前景。[结果]除1例病人因术后短期再次创伤意外,行2次手术更换为传统螺钉内固定外,其余病人均在术后6周开始部分负重功能锻炼,术后第3个月功能平均评分达到满意,术后第6、12个月功能平均评分达到优良,X线片未发现内固定失效。[结论]Suture Button装置治疗下胫腓联合损伤具有技术简单、手术时间短、内固定器物理特性符合人体正常解剖生理、固定强度足够、无需2次手术取出等多项优势,可能成为下胫腓联合损伤新的治疗标准。

作者： William henry Davies 不详天津雯雯

【赏析】William henry Davies，英国诗人，他的诗清新自然，不带一丝烟火气。他的天分是萧伯纳发现的，萧伯纳曾称赞他道：“我还没有念三行，就看出这个作家是个真诗人。”这首诗《月》颇为清净自然。它描写了作者月下的所见。
