Hitherto secret wartime work was widely disseminated, and new military, industrial and other applications of the emerging discipline were identified.
An extraction procedure employing chlorinated cobalt dicarbollide in combination with organophosphorus extractants (used successively or simultaneously) was developed for reprocessing of wastes from military industry.
Zhdanov, rector of the Rostov State University (RSU), received the following letter from Moscow signed by the Commander of the Dzerzhinskii Military Academy (now the Peter the Great Academy of Strategic Rocket Forces):
Government military spending on both sides provided funding to explore new acoustoelectronic concepts in universities, institutes, and major defense companies.
Recently, ultraviolet photoelectronics emerged in response to the needs of medicine, biology, military equipment, and the problem of the hole in the ozone layer.
Three new species of fleas are herewith decribed from different regions of China.A series of specimens of Frontoptylla aspiniformis sp. nov. was collected from Ochotonadaurica, Citellus dauricus and Myospalax fontanieri from Kansu and Shensi. The new speciesis named from the lack of characteristic spiniform bristle on the hind apical corner of the movablefinger. This new species is allied to Frontopsylla wagneri Ioff, 1927. A pair of Ctenophthalmus quadratus sp. nov. was taken from a nest of an undetermined...
Three new species of fleas are herewith decribed from different regions of China.A series of specimens of Frontoptylla aspiniformis sp. nov. was collected from Ochotonadaurica, Citellus dauricus and Myospalax fontanieri from Kansu and Shensi. The new speciesis named from the lack of characteristic spiniform bristle on the hind apical corner of the movablefinger. This new species is allied to Frontopsylla wagneri Ioff, 1927. A pair of Ctenophthalmus quadratus sp. nov. was taken from a nest of an undetermined wildrodent from western Yunnan. The name of the new species is used to denote the characteristic squareshape of the posterior lobe of the immovable process of the clasper. The new species is allied toCtenophthalmus yunnanus Jord. 1932 and Ct. formosana Svihla 1942. Three pairs of fleas misidentified, redescribed and figured in 1956 (egg, larval and pupal stagesdescribed) as Stenopnia sidimi Marik. collected from the nests of Apodemus agrarius in Shanghaiare recently rechecked and found to be a new species. It is named Stenoponia shanghaiensis nov. sp.and it is closely allied to S. sidimi. A table showing the differential characteristics of the two Steno-ponia is given.' Holotypes (males) and allotypes (females) of the three new species are all deposited in theCollection of the Military Academy of Medical Sciences. Paratypes of Frontopsylla aspiniformis aredeposited in the National Institute of Parasitology, Shanghai and the Northwestern AgriculturalCollege, Shensi. Paratypes of Stenponia shanghaiensis were deposited in the Division of Parasi-tology, Second Military Medical College, Shanghai.
The theory presented in the previous paper [1] has a wide class of applications in physics and engineering mechanics. In this paper, we aim principally to show its application to general elasticity (elasticity of generalized media, polar elasticity, or called no-linear asymmetric elasticity in some literatures). A generalized Euler's Kinematic formula is first derived by using the theory [1], it is seen that the method of intrinsic comoving coordinates for deformable body is a natural extension of that method...
The theory presented in the previous paper [1] has a wide class of applications in physics and engineering mechanics. In this paper, we aim principally to show its application to general elasticity (elasticity of generalized media, polar elasticity, or called no-linear asymmetric elasticity in some literatures). A generalized Euler's Kinematic formula is first derived by using the theory [1], it is seen that the method of intrinsic comoving coordinates for deformable body is a natural extension of that method of moving coordinates used in rigid body dynamics. By means of the theorems of momentum and moment of momentum,and the principles of conservation of mass and energy, we found the fundamental equations of general elasticity, certain improvements have been made in comparison with the works of Eringen and Nowacki in polar elasticity. Some of the applications will be left for subsequent papers. Due to the interests in mining and military, we pay special attention in the Appendix to the finite motion of one dimensional shock wave in rock. Theoretical results obtained were used to the interpretations of the equal velocity paradox in shock wave attenuation which was noted by Rinehart, to the tensile fracture phenomena caused by the trailing part ,of . compressive shock wave, and to the influence of couple stress. These .results are also useful in discernning .the change of wave velocity related to earth stress in the precursor of earthquake.
This report gives a general discussion of the lateral-directional dynamic flying qualities of military airplanes, based mainly on the Military Flying Qualities Specification of Piloted aircraft, MIL-F-8785 B issued in 1969, to provide the necessary background for drafting the flying quality specification of our own country.The lateral-directional mode characteristics is discussed first, followed by a discussion on lateral-directional dynamic response characteristics, the order being the same as that...
This report gives a general discussion of the lateral-directional dynamic flying qualities of military airplanes, based mainly on the Military Flying Qualities Specification of Piloted aircraft, MIL-F-8785 B issued in 1969, to provide the necessary background for drafting the flying quality specification of our own country.The lateral-directional mode characteristics is discussed first, followed by a discussion on lateral-directional dynamic response characteristics, the order being the same as that adopted by MIL-F-8785 B.In the discussion about mode characteristics, comparison is made between 8785 B and those specifications issued before 8785 B, such as 8785, AP970 and OTT, and explanation of the background for- the adoption of each criterion is given wherever possible.In the discussion about response characteristics, an analysis of the difference between 8785 B and "Proposed Revision to MIL-F-8785 B" (ref 5) is given.
