The paper is focused on different kinds of gravity results obtained in Shults Cape Observatory for 2010 -2015. Gravity observation is interpreted together with GPS observation data which was obtained from 2012 to 2015 at the same station, The station is situated on Gamov peninsular （42.58° N, 131.15° E, Russia） at the coast of Japan Sea, This region constitutes the eastern boundary of Eurasia. This major continental tectonic feature is associated with a seismic activity, high heat flow and anomalous thickness of earth＇s crust. The goal of the observation was the investigation of gravity variation with time and seismicity situation monitoring. Gravity observation was developed at special basement by absolute gravimeter （GABL type） and by spring gravimeter （SCINREX CG-5and gPhone type）. Tidal models were tested by results of observation with spring gravimeters. Reduction task was solved, as the experimental data received from different points of Shults Cape Observatory was used. Applied reduction coefficient is 203.3 12Gal m l, and agrees with theoretical calculation. Next goal was studying structure of earth＇s crust by means of gravity models. Gravity anomaly varied from 30 mGal to 46 mGal, which also depend on difference reference system, Experimental results were used for testing of the structure of continental boundary, which also depends on the sea bottom flexion. Thickness of elastic layer was estimated from 12 km to 18 km by using different models.

This work presents the results of complex gravity observation performed at Shults Cape, Gamov peninsula (42.58°N, 131.15°E), Russia. Absolute laser gravimeter GABL type and Scintrex type relative gravimeter were used for measurement. To investigate the accuracy of tidal corrections we compared the observed tidal parameters of the main tidal waves O1 and M2 with modeled ones computed from 6 different ocean tidal models: CSR4, FES02, FES04, GOT00, NAO99 and TPX06. After discussion a theoretical model based on TPX06 ocean tides model and DDW99 non hydrostatic body tides model was used for tidal correction of absolute gravity data. Preliminary estimate of gravity effect induced by the Tohoku-Oki earthquake of11 March 2011Mw = 9.0 at Primorye territory (Russia) was found to be 5.1 ± 2.0 μGal. Co-seismic crustal displacements revealed by GPS data at Far EastRussiacontinental coast are also investigated. Volumetric dilatation of this area is observed at +1.7 × 10-8 level.

Nitrite pre-treatment of dewatered sludge for microbial fuel cell application

引用

Journal of Environmental Sciences 2019年第3期31卷 148-155页

作者： Abdul Rasyid ruslan Vel Murugan Vadivelu School of Chemical Engineering Universiti Sains MalaysiaEngineering Campus

The effect of pre-treatment of dewatered sludge using different nitrite concentrations and p H for microbial fuel cell(MFC) application was investigated. The results show that the addition of nitrite was feasible to increase the solubilization rate of the sludge and may reduce mass transfer limitation at the anode. This helped the MFC to reach higher voltage and to generate more power. The higher free nitrous acid(FNA) concentration under the acidic condition helped to increase sludge solubilization. However, under an alkaline condition, during which the FNA concentration was relatively low, the solubilization of the sludge was higher. The highest voltage and power density produced was 390 mV and 153 mW/m^2, respectively, with the addition of nitrite at 100 mg-N/L and pH 9. Furthermore,it was found that elevated levels of FNA could inhibit electrogenic bacteria thus reducing power generation.

Archaeological Mineralogy and the Dawn of Gemmology:Prehistoric(7th-5th Millennium BC)Gem Minerals and Gold from the Balkans（South-East Europe）

引用

宝石和宝石学杂志 2019年第4期21卷 25-35页

作者： ruslan I.Kostov University of Mining and Geology "St.Ivan Rilski"

The territory of the Balkan Peninsula in SE Europe is reviewed, from the point of gemmology, as the cradle of gem and decorative minerals and metals in European prehistory. During the local Neolithic period (end of 7 th -6 th millennium BC), as material for tools or for beads, nephrite (with the earliest known Balkan nephrite culture), jadeite-omphacite and quartz (different varieties) were introduced to make pendants and idols. Large quantities of copper and gold artifacts are known since the Chalcolithic period (5 th millennium BC)(unique for the region;the largest in number of gold artifacts is the Varna I Chalcolithic necropolis in Bulgaria). The gemmological materials in the Balkans are known for malachite, antigorite serpentinite, turquoise, rock crystal, carnelian, jasper, jet and obsidian. In the Varna I necropolis (mid 5 th millennium BC) are recorded the first known complex faceted carnelian beads with 32 facets, as well as some of the most important gemmological techniques and procedures such as faceting, tumbling, annealing, miniaturization and standardization. As pigments for pottery, cinnabar, graphite and gold were used in different prehistoric sites. The earliest salt production in the Balkans is known from sites in Romania and Bulgaria, and because of its trade, salt is positively linked to a population rich with prestigious goods. The introduced possible Chalcolithic weight unit “van”(2 carats) is supposed to be the earliest known in prehistoric times.

Tribological study on the surface modification of metal-on-polymer bioimplants

Frontiers of Mechanical Engineering 2022年第2期17卷 103-115页

The tribological performance of artificial joints is regarded as the main factor of the lifespan of implanted prostheses. The relationship between surface roughness and coefficient of friction (COF) under dry and lubricated conditions is studied. Results show that under dry test, friction coefficient is not reduced all the time with a decrease in surface roughness. On the contrary, a threshold of roughness value is observed, and frictional force increases again below this value. This critical value lies between 40 and 100 nm in Sa (roughness). This phenomenon is due to the transfer of friction mechanisms from abrasion to adhesion. Under wet test, COF always decreases with reduction in surface roughness. This result is mainly attributed to the existence of a thin layer of lubricant film that prevents the intimate contact of two articulating surfaces, thus greatly alleviating adhesion friction. Furthermore, surface texturing technology is successful in improving the corresponding tribological performance by decreasing friction force and mitigating surface deterioration. The even-distribution mode of texturing patterns is most suitable for artificial joints. By obtaining the optimal surface roughness and applying texturing technology, the tribological performance of polymer-based bioimplants can be greatly enhanced.

Effect of laparoscopic abdominal surgery on splanchnic circulation: Historical developments

World Journal of Gastroenterology 2014年第48期20卷 18165-18176页

With the developments in medical technology and increased surgical experience, advanced laparoscopic surgical procedures are performed successfully. Laparoscopic abdominal surgery is one of the best examples of advanced laparoscopic surgery (LS). Today, laparoscopic abdominal surgery in general surgery clinics is the basis of all abdominal surgical interventions. Laparoscopic abdominal surgery is associated with systemic and splanchnic hemodynamic alterations. Inadequate splanchnic perfusion in critically ill patients is associated with increased morbidity and mortality. The underlying pathophysiological mechanisms are still not well understood. With experience and with an increase in the number and diversity of the resulting data, the pathophysiology of laparoscopic abdominal surgery is now better understood. The normal physiology and pathophysiology of local and systemic effects of laparoscopic abdominal surgery is extremely important for safe and effective LS. Future research projects should focus on the interplay between the physiological regulatory mechanisms in the splanchnic circulation (SC), organs, and diseases. In this review, we discuss the effects of laparoscopic abdominal surgery on the SC.
