Misja salezjańska Chiu Chow w Chinach
No full textThis article tells the story of Shiu Chow\u27s Salesian Mission in China (1918–1951), became Apostolic Vicariate (1920) and then diocese (1948). The Mission had lived a enormous development under the three Salesian bishops: Msgr. Versiglia (1918–1930), first Vicar Apostolic and Salesian protomartyr, Monk. Canazei (1930–1946), the Inspector in China and then Vicar Apostolic of Shiu Chow, Msgr. Arduino (1948–1951), director of the Salesian schools in Shanghai and first bishop of the diocese of Shiu Chow. Thriving mission activity and development closes the expulsion of the Salesian missionaries, the FMA nuns and Msgr. Arduino (December 2, 1951) from China from the Communists. The last part is dedicated to the Polish Salesian missionaries working in Shiu Chow Mission: coad. J. Urban, Ps. W. Spinek, sac. T. Szeliga, priest W. Wieczorek. The material for the article I found in the books of don. M. Rassiga, missionary and chronicler of Shiu Chow mission, I kindly offers to the author himself.Ten artykuł opowiada historię misji salezjańskiej Shiu Chow w Chinach (1918–1951), został wikariatem apostolskim (1920), a następnie diecezją (1948). Misja żyła a ogromny rozwój pod rządami trzech biskupów salezjańskich: ks. Versiglia (1918-1930), pierwszy wikariusz Pierwszy męczennik apostolski i salezjański, ks. Canazei (1930–1946), inspektor w Chinach, a następnie wikariusz Apostolski Shiu Chow, ks. Arduino (1948-1951), dyrektor szkół salezjańskich w Szanghaju i pierwszy biskup diecezji Shiu Chow. Prężnie rozwijająca się działalność i rozwój misji dobiegają końca wypędzenie salezjanów misjonarzy, sióstr CMW i ks. Arduino (2 grudnia 1951) od Chiny od komunistów.

On Chow weight structures for cdh-motives with integral coeffcients
No full textThe main goal of this paper is to define a certain {\it Chow weight
structure} on the category
of (constructible) -motives over an equicharacteristic
scheme . In contrast to the
previous papers of D.~H\'ebert and the first author on weights for
relative motives (with rational coefficients), we can achieve our goal for motives
with integral coefficients (if ; if then we
consider motives with -coefficients). We prove that the
properties of the Chow weight structures that were previously
established for -linear motives can be carried over to this "integral"
context (and we generalize some of them using certain new methods). In this paper we mostly study
the version of defined via "gluing from strata"; this enables
us to define Chow weight structures for a wide class of base schemes.
As a consequence, we certainly obtain certain (Chow)-weight spectral
sequences and filtrations on any (co)homology of motives.The work is supported by RFBR (grants no. 14-01-00393A and 15-01-03034A). The first author is also grateful to the Dmitry Zimin's Foundation "Dynasty"
Buchbesprechung: S.-C. Chow: Controversial Statistical Issues in Clinical Trials
No full text[english] The book of Chow gives an overview over many controversial aspects in conducting and analyzing of clinical trials. The author of this book review (translation of the ISCB Bulletin) concludes, that all parties involved in clinical trials should have access to the book to enable them to cope with the most important controversial aspects in planning and execution of clinical studies

Chow rings and decomposition theorems for families of K3 surfaces and Calabi-Yau hypersurfaces

LEHN’S FORMULA IN CHOW AND CONJECTURES OF BEAUVILLE AND VOISIN
No full text© The Author(s) 2020. Published by Cambridge University Press. The Beauville-Voisin conjecture for a hyperkähler manifold states that the subring of the Chow ring generated by divisor classes and Chern characters of the tangent bundle injects into the cohomology ring of. We prove a weak version of this conjecture when is the Hilbert scheme of points on a K3 surface for the subring generated by divisor classes and tautological classes. This in particular implies the weak splitting conjecture of Beauville for these geometries. In the process, we extend Lehn's formula and the Li-Qin-Wang algebra action from cohomology to Chow groups for the Hilbert scheme of an arbitrary smooth projective surface
Optically Transparent Micro fluidic Systems Integrated with Carbon Nanotube Sensors
No full textIn this paper, we present carbon nanotube (CNT) based thermal shear stress sensors integrated inside optically transparent Polymethylmethacrylate (PMMA) microfluidic systems. The sensors were fabricated on PMMA substrates by batch assembling multi-walled carbon nanotubes (MWNTs) as sensing elements between microelectrode pairs using AC dielectrophoretic (DEP) technique. PMMA chambers were fabricated using SU-8 molding/hot-embossing technique. Then, the PMMA substrate with a micro chamber and vortex micropump was bonded to the other PMMA substrate embedded with the MWNT sensor array to form a closed flow chamber. Experiments showed that the CNT sensors could detect volumetric air flow rate in the order of 10-8m3/s inside this microchannel system. We have also proved that upon exposure to constant liquid (DI-water) flow, the electrical resistance of the CNT sensor was found to increase linearly at low activation current of 100μA. And a linear relation between the change of output resistance and one-third power of flow rate was observed for flow rate from 0.3 to 2.3m/s. This result proved that the CNT sensors work with the same principle as conventional MEMS based thermal shear stress sensors, but only require ultra-low activation power (~μW) to achieve comparable sensitivity, which is three orders of magnitude lower than conventional MEMS polysilicon based flow sensors
Lateral tibial condyle reconstruction by pedicled vascularized fibular head graft: Long-term result
No full textThe technique of pedicled vascularized fibular graft for lateral tibial condyle reconstruction after en bloc resection of aggressive giant cell tumours was described by SP Chow et al. Early follow-up of two patients was presented in 1986. We present the 25 years follow-up of one patient with a literature review of alternative present day treatment options. The patient maintained community ambulant status despite developing late stage osteoarthritis. Although this procedure is performed rarely, it remains an alternative to the more sophisticated treatment options making it a useful method in centres with limited facilities and expertise. © 2011 The Author(s).published_or_final_versio
Integrated SWCNT sensors in micro-wind tunnel for air-flow shear-stress measurement
No full textWe have developed SWCNT sensors for air-flow shear-stress measurement inside a polymethylmethacrylate (PMMA) “micro-wind tunnel” chip. An array of sensors is fabricated by using dielectrophoretic (DEP) technique to manipulate bundled single-walled carbon nanotubes (SWCNTs) across the gold microelectrodes on a PMMA substrate. The sensors are then integrated in a PMMA micro-wind tunnel, which is fabricated by SU-8 molding/hot-embossing technique. Since the sensors detect air flow by thermal transfer principle, we have first examined the I–V characteristics of the sensors and confirmed that self-heating effect occurs when the input voltage is above ~1 V. We then performed the flow sensing experiment on the sensors using constant temperature (CT) configuration with input power of ~230 μW. The voltage output of the sensors increases with the increasing flow rate in the micro-wind tunnel and the detectable volumetric flow is in the order of 1 × 10−5m3/s. We also found that the activation power of the sensors has a linear relation with 1/3 exponential power of the shear stress which is similar to conventional hot-wire and polysilicon types of convection-based shear-stress sensors. Moreover, measurements of sensors with different overheat ratios were compared, and results showed that sensor is more sensitive to the flow with a higher overheat ratio
