A West Kentucky mine operation in No. 11 seam encountered floor heave, due to the localized increase in the thickness of the fireclay mine floor. Floor heave has overridden seals installed in two mined out panels. The third seal's location was planned for isolating that area from the Mains. A plan of support has been developed to prevent repetition of the floor heave and related problems outby the seals. The applied ground control measures were successful. An attempt of a 3D numerical modeling was made; thus, it would match the observed behavior of the mine floor and could be used as a design tool in similar conditions. The paper describes sequence of events, an applied mitigation ground control system, and the first stage of numerical modeling.

Cervical carcinogenesis consists of natural occurring spontaneous cellular processes which may lead to self-organized dissipative structures of cervical cancers what was first explained in 1977 after several years of my biochemical, biophysical, hormonal and clinical studies. That was possible thanks to monograph “Biochemie der Tumoren” written in 1942 by Nobel Prize winner H. von Euler with my master Prof. B. Skarzynski. Today I express my gratitude to Nobelist Harald zur Hausen and his team for they discovered the nuclide sequences of HPV in genomes of cervical cancer cells which opened the possibility to describe the causal role of information in formula of reality. Vaccines built from the protein capsid of HPV have proved only the pathogenic information about the virus because of its lack of DNAs. All the theories of carcinogenesis have properly described this event from methodologically different point of view. The point is that one should understand the thermodynamic rules underlying each of these approaches. Neoplasms are self-organized from the cells of the patient, who did not provide the necessary conditions for cellular metabolism as defined in the moment of appearance of its zygote. In light of medical thermodynamics all oncogenic factors can divide into sufficient or necessary to events for creating a dissipathogenic cellular status. Cervical cancer is a tumor associated with the human papillomavirus as only its pathogenic dissipathogenic factors, but the genome of cervical carcinoma cells maybe the original source of many types of HPV from the peeled off cancer cells of the uterine cervix. Many things are known to increase the risk of carcinogenesis which as a natural process is an alternative of cellular or social death. Neoplasm cell is an effect of carcinogenesis, but not a causal point at which it begins its existence.

负序方向纵联保护具有能够保护故障全过程、不受线路分布电容和系统振荡影响等优点,特别适用于大容量、远距离超特高压输电线路,但无法应用于非全相运行方式,影响了其普及应用。针对该问题,文中利用系统正常运行、非全相运行和非全相运行再故障后3种状态下的相电压和电流相量,虚拟构造母线侧负序电压;并在计算过程中抵消非全相运行时系统中存在的负序电流分量,实现了一种适用于非全相运行方式下的输电线路负序方向纵联保护方法;使得负序方向纵联保护可以适用于输电线路全部运行状态,降低了负序方向纵联微机保护的复杂性,具有较高的实用价值。

特高压交流长线路上,测量阻抗与故障距离呈双曲正切函数关系,因此接地阻抗继电器的动作特性受过渡电阻的影响严重,无法直接使用。传统高压、超高压线路普遍采用零序电抗继电器来提高抗过渡电阻能力,本文评估了零序电抗继电器在特高压线路上的适用性;针对存在的保护动作区缩小、灵敏度降低的问题,采用负序电流作为极化量,并考虑了负荷电流的影响,提出了一种适用于特高压交流长线路的负序电抗继电器,仿真结果表明该继电器具有保护区稳定、灵敏度高的优点。
