Hip joint disease associated with progressive amyloid deposition in uraemic patients receiving chronic haemodialysis treatment often requires treatment by joint arthroplasty. The aim of this study was to determine whether β2‐microglobulin amyloid deposition occurred in the periprosthetic tissues of arthroplasties that had undergone aseptic loosening and required a revision procedure.


SUMMARY Acute liver failure (ALF) during pregnancy represents a rare, but life-threatening condition for both mother and fetus. In severe cases, liver support therapy may bridge selected patients to delivery or liver transplantation. We report the case of a 34 years old 12 weeks pregnant woman with ALF, admitted to the Intensive Care Unit (ICU) for grade 3 hepatic encephalopathy and severe cholestasis, in whom we applied 3 sessions of MARS (Molecular Absorbent Regenerating System) therapy. After liver dialysis, hepatic function improved: bilirubin and ammonia levels decreased, lactate levels returned within normal range and fibrinogen and prothrombin time returned to normal values. Due to severe complications, including ALF and severe acute respiratory distress syndrome, termination of pregnancy was decided by her current obstetrician. During ICU stay the patient developed severe sepsis unrelated to ALF and died. Despite the outcome, liver improvement cannot be disregarded and further research is needed in order to establish exact timing for liver support therapies and to select patients that can have highest benefits.

Large scale biometrics projects rely on capturing images/signal from multiple sensors. For example, in India's Aadhaar project, multiple fingerprint sensors of different make and model are used for data collection. Similarly, in law enforcement applications, different agencies use different fingerprint sensors. These scenarios cause two potential problems: (i) sensor inter-operability and (ii) protecting/recording chain of evidence. While sensor inter-operability in fingerprints is a well studied problem, automatically recording chain of evidence is a relatively less explored research problem. For both the problems, one potential approach includes automatically identifying sensors based on the input image. This paper presents a novel fingerprint sensor identification algorithm based on multiple features such as Haralick, entropy, statistical and image quality features. The proposed algorithm is evaluated on a large database with 30,000 images with 15 fingerprint sensor classes. The proposed algorithm achieves an accuracy of 96% and computationally requires less than 10 milliseconds for an image.


There was elaborated a method for calculating magnetic fields of the Solar
System planets. It is based on the quantum theory of electroconductivity of
metals and semiconductors. The latter helps to calculate thermoelectrical
processes, always taking place in the bowels of "hot" planets. Main elements of
those processes are planetary temperature gradients, thermo electromotive
force and radially directed thermoelectrical currents, which are associated
with Seebeck effect. Thermo electromotive force causes directional movement
of planetary thermoelectrical currents both in metal cores and other conductive
shells of planets. Those currents are big and they generate magnetic fields
of proportional intensity. The capacities of the calculation method were tested
while finding the reason why the Jupiter magnetic field is such complicated.
As a result it was specified that the source of the main magnetic field of a planet
is its metal core and the source of an additional magnetic field is the layer
of liquid metal hydrogen. There was also found the third source of a local
magnetic field of low intensity along the circular zone of the equatorial region.
The conclusion that the Jupiter's main magnetic field has a polarity opposite
to the Earth's one.


The rhyme scheme (1121 2231 2232 3341) is given by the binary weight (OEIS A000120 [2]) of the line numbers. Also known as the "Hamming weight," this is the sum of the number's binary digits. The OEIS entry has many interesting facts about this sequence. The respective rhymes are used (1 + 4, 6, 4, 1) times, and this relationship with ( n j ) generalizes if the form is extended to 2 lines. Coincidentally, Omar Khayyam was one of the pioneers of binomial coefficients: what is known in the West as "Pascal's triangle" has been called the "Khayyam triangle" [1] in Iran!


Ivabradine is a If current inhibitor in SA node. [2,3] Currently, it is the only agent shown to clinically lower heart rate with no negative inotropism or effects on conduction and contractility.[2,3] Ivabradine selectively inhibits the pacemaker If current in a dose dependent manner at concentrations that do not affect other cardiac ion currents. Blocking this channel reduces cardiac pacemaker activity, slowing the heart rate and allowing more time for blood flow to the myocardium. The dosing is started at 5 mg twice daily, and if tolerated can be safely continued to 7.5 mg twice daily. Food delays the absorption of ivabradine. As metabolism involves cytochrome P4503A4 (CYP3A4), concurrent use of inhibitors of CYP3A4 (macrolide antibiotics, azole antifungals) is contraindicated. Metabolites are excreted in urine and feces. Main t 1⁄2 is 2 h (70-75% of area under the curve) in plasma and has an effective t 1⁄2 of 11 h. Total clearance is 400 ml/min and renal clearance is 70 ml/min. The various adverse effects of ivabradine includes luminous phenomenon (due to blockade of Ih channel in the retina, which resembles If cardiac channels), atrioventricular block, ventricular extrasystole and bradycardia.[3]


The Basel New Capital Accord firstly incorporates legal risks into the capital regulatory framework for banks,which poses new requirements for the construction of overall risk management system in the commercial bank and the perfection of banking regulatory regime.We should borrow the integrated experience of risk management and advanced concepts of supervision embodied in the New Basel Capital Accord,and enact guidelines to establish risk-oriented supervision relating to legal risks from the perspectives of making clear the demonstrative pattern of legal risk,leading commercial bank perfect their organization of risk management and stimulating it to explore the technology and methods of risk management.


The progression of chronic kidney disease (CKD) occurs faster in males (M); however, the underlying mechanisms remain poorly understood. A potential contributing factor to sex differences in CKD progression is differences in glomerular capillary morphology. Glomerular capillaries with larger radii or longer lengths may predispose capillaries to barotrauma-induced injury. The goal of the present study was to assess glomerular capillary morphology in M vs. female (F) rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (RCAP) and length (LCAP) would be greater in M rats.This study utilized rats (8-11-week old, Charles River) with intact kidneys (n=4 M, n=4 F) and UNX (n=4 M, n=4 F) provided a 0.4% NaCl diet and water ad libitum. Kidneys were perfusion-fixed with 2% paraformaldehyde and 2.5% glutaraldehyde in phosphate buffered saline (pH=7.4). The left kidney was excised and a 3 mm transverse section through the midline of the kidney was selected for further processing. Multiple 1 mm3 cubes were randomly excised from the left, middle, and right regions of the outer cortex and embedded in EPONTM. The 1 mm3 cubes were sectioned (1 μm), placed on slides, and stained with toluidine blue. Four glomeruli from each region were randomly selected for stereological analysis using STEPanizer (Tschanz SA et al. J. Microsc. 243(1):47-59, 2011). Values of RCAP and LCAP were derived using standard stereological formulas (Nyengaard JR J. Am. Soc. Nephrol. 10(5):1100-1123, 1999). Effects of sex and UNX on body weight (BW), kidney weight (KW), glomerular volume (VG), RCAP, and LCAP were assessed with a 2-way ANOVA with Sidak post hoc analysis. All data are mean±SE and P<0.05 was considered statistically significant.In M vs. F rats with intact kidneys, BW (289±7 vs. 230±6 g) was greater (P<0.05) in M, but no significant differences were observed in KW (1.4±0.1 vs. 1.2±0.1 g), VG (0.65± 0.02 vs. 0.62±0.04 x 106 μm3), RCAP (2.8±0.1 vs. 2.8±0.1 μm), or LCAP (7.3±0.3 vs. 7.1±0.1 mm). In F rats with UNX vs. intact kidneys, BW was not significantly different; however, KW, VG, RCAP, and LCAP were 1.1-1.6-fold greater (P<0.05) in rats with UNX. In M rats with UNX vs. intact kidneys, BW, KW, and VG were 2-3.5-fold greater (P<0.0001), and RCAP and LCAP were 1.1-1.5-fold greater (P<0.05) in rats with UNX. M rats with UNX exhibited a greater (P<0.0005) BW (560±21 vs. 270±11 g), KW (4.2±0.2 vs. 1.8±0.1 g), VG (1.3±0.1 vs. 1.0±0.01 x 106 μm3), and LCAP (11.0±0.3 vs. 9.7±0.3 mm) as compared to F rats with UNX. RCAP was similar in M and F rats with UNX (3.3±0.1 vs. 3.1±0.1 μm). These data indicate that M rats exhibit greater compensatory increases in LCAP following UNX as compared to F rats. The greater LCAP in M may result in reduced podocyte density and contribute, in part, to their greater susceptibility to hypertensive injury and CKD progression as compared to F rats.

In this paper, we examine recently recovered data from two sites belonging to different chronological periods in the Lurin j Valley of the Perúvian central coast. We discuss in a comparative framework how rural elites in the settlements ofLote B \ and Panquilma saw their lives transformed while dealing with the intrusion of the Lima polity and the Inkas, respectively. Each site presents evidence of at least two sets of ritual and feasting activities, one in domestic contexts and another associated with monumental architecture. We propose that in both cases the rural elites of these two sites implemented a set of mutually constituted strategies when dealing with outside political influence. These strategies were oriented upwards to deal with changes at the regional level as well as downwards to maintain their privileged position in their own communities during moments of change. These parallel strategies were developed through a complex interplay of economics, ideology, and public prestige available to the elites. In the case of Lote B, the rural elites acquired economic power, consolidating a loose level of leadership by sacrificing part of their public prestige. At Panquilma, we find evidence for the existence of rural elites with a solid economic position who were compelled to search for legitimization and prestige in the local realm rather than by participating in a new and larger economic system.


The results of a field study by Gencturk, Childers, and Ruekert conducted in the United States of 78 product-market units support the appropriateness of conceptualizing IMI as a multifaceted behavior of a business. The findings highlight the fact that businesses can and do use means other than direct ownership as a way of supporting their foreign marketing activities. In fact, the study findings confirm that businesses are increasingly relying on independent agents or partners to perform foreign marketing activities. This does not imply that these businesses relinquish their international marketing involvement. The findings suggest that a business can be highly involved in foreign marketing activities through administrative and/or operational involvement even though internal or external constraints prevent it from using the traditionally advocated legal ownership route.


Two‐dimensional polymeric loops of N hard disk monomers are subject to a bending rigidity κ. The mean square radius of gyration 〈R2G〉, mean area 〈A〉, shape parameter Σ=〈R2Gmin〉/〈R2Gmax〉, and specific heat are studied as a function of N and κ. Scaling behavior is governed by the combination y∼N/κ when N, κ→∞. In the rigid limit, y→0, 〈R2G〉 scales as N2 and 1–Σ varies as yψ with ψ=1/2. Conversely, in the soft limit, y→∞, 〈R2G〉 scales as y−ω with ω=2(1−ν)=1/2 and Σ→0.39. The scaling domain is extended beyond the soft limit by using a nonlinear scaling field incorporating an effective rigidity κ(κ).


Chitosan and chitosan modified carboxymethyl were used to enhance performances of paper packaging. Chitosan 1.0 wt% and chitosan modified carboxymethyl solutions with concentrations of 0.25; 0.5 and 1.0 wt% were manually applied on paper surface using dip coating method. Effects of chitosan coatings on antibacterial properties of the paper were investigated. The antimicrobial activity of chitosan against gram-positive (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli) was found to be enhanced when chitosan and chitosan modified carboxymethyl solution were entrapped within paper. Further paper coated chitosan and chitosan modified carboxymethyl has higher antibacterial activity againt S. aureus rather than E. coli.

This volume contains descriptions and results of: design support and development tests, which assisted in finalizing and substantiating the designs for the cargo handling components; the integrated test rig program, which demonstrated feasibility and achievement of design, functional, performance and reliability characteristics; and the disassembly and teardown inspection of selected components utilized on the integrated test rig.


This study examined the awareness of the healthcare accreditation system, job stress, organizational commitment, and the turnover intention to determine the effects of these factors on the turnover intention of small and medium sized hospitals. A total of 202 nurses who worked in hospitals with less than 500 beds located in Gyeonggi-do, participated in this study. Questionnaires were given to the nurses who experienced healthcare accreditation, and data were collected between 1 December 2015 and 30 March 2016. As a result, the factors and general characteristics, influencing the turnover intention were found to be age (F=4.68, p<.001), marital condition (F=3.92, p<.001), and department of work (F=3.23, p<.008). The turnover intention was negatively correlated with the awareness of the healthcare accreditation system (r=-.46, p<.001) and nursing organizational commitment(r=-.35, p<.001), but positively correlated with the job stress (r=.21, p=.002). Regression analysis showed that the turnover intention of nurses from small and medium sized hospitals had 22.0% on the organizational commitment, department type, and job stress. Therefore, to decrease the nurses' the turnover intention, managers of small and medium sized hospitals need to draw up measures to support job involvement and policy improvement. The results also showed the difference in turnover intention according to the department type. Accordingly, there is a need for a differentiated approach according to the department of work, such as a special unit, ward, and outpatient department.


The present invention is related to a procedure for in creasing the chemisorption capacity of carbon impreg nated with metallic compounds. By a large number of tests it is amply demonstrated that such capacity may be significantly increased with regard to poisonous gases and gaseous industrial effluents simply by irradi ating the impregnated carbon by gamma radiation to a dosage of at least 1 Mrad before the actual sorption process. The said chemisorption capacity may be fur ther increased by performing the irradiation in a nitro gen atmosphere, preferably at a higher partial pressure of nitrogen than in air at atmospheric pressure.


Abstract : A comparison of the test results obtained for the unaged French and 2024-T3 (bare and hard anodized) alloys suggests that the resistance of all materials to raindrop erosion is identical. Superior performance of the hard anodized Alloy 2024-T3 sample was not observed during the erosion testing. Post- test examinations of the hard anodized 2024-T3 sample indicate that the performance of the coating was limited by spalling of the coating from the substrate. A review of the literature suggests that this condition is due to abnormal surface roughness of the anodic coating. This condition, which can be minimized with the application of silicone waxes (or similar surface treatments) to the coated surfaces, does contribute to poor chemical and impact resistance. No pretest surface characterizations were performed on this material. In summary, the results of this program suggest that Alloy 2024-T3 be considered as a candidate replacement material for the French alloy that is currently being used on the outer wing slats of the HU-25A aircraft.

Mulberries ( Morus spp) are historically grown in particular microclimatic regions in Eastern Anatolia, including Aras valley. In the valley, mulberries are one of the ancient crop and used for several purposes by local people. The aim of the present study was to first time evaluate organic acids, sugars, vitamin C, antioxidant capacity (TEAC assay, Trolox Equivalent Antioxidant Capacity). and phenolic compounds of the historical black and white mulberry genotypes growing Aras valley in Turkey. Results showed that, species and genotypes strongly influenced the chemical content and antioxidant capacity ( p <0.05). Malic acid was the main organic acid in all genotypes and ranged from 1.130 to 3.040 g/100 g. Among sugars, fructose and glucose are predominant and were between 4.177 and 7.700 g/100g and 5.337 and 8.573 g/100g in all mulberry genotypes, respectively. The black mulberry genotypes showed remarkably higher antioxidant capacity determined by TEAC assay (10.167 to 14.400 µ mol TE/g) compared to white mulberry genotypes (6.170 to 9.273 µmol TE/g). Chlorogenic acid and rutin was the main phenolic compound.


Abstract White perch, Morone Americana, first appeared in the Laurentian Great Lakes system in 1951 and flourished in the Bay of Quinte, Lake Ontario throughout the 1950s and 1960s. The species extended its range to Lake Erie and Lake St. Clair and more recently (1983) to Saginaw Bay, Lake Huron. Self sustaining populations of white perch are now established in western Lake Erie (1974) and Lake St. Clair (1979). Factors contributing to successful colonization by white perch include: suitability of habitat within the range, ability to spawn over a variety of substrates, and high egg production.


A multimodal imaging study of chabazite is used to show the distribution of and discriminate between different emissive deposits arising as a result of the detemplation process. 3D confocal imaging, fluorescence lifetime imaging, spectral imaging, and Raman mapping are used to show three different types of emissive behaviours each characterised by different spatial distributions, trends in lifetime, spectral signals, and Raman signatures. A notable difference is seen in the morphology of agglomerated surface deposits and larger subsurface deposits, which experience lifetime augmentation due to spatial confinement. The distribution of organic residue throughout the crystal volume is comparable to XRF mapping that shows Si enrichment on the outer edges and higher Al content through the centre, demonstrating that a fluorescence-based technique can also be used to indirectly comment on the compositional chemistry of the inorganic framework.


The introduction of NIPT into clinical medicine from 2012 was greeted with great acclaim by physicians and patients. There was talk of breakthrough, NIPT replacing amniocentesis, diagnostic testing procedure and much more. However, clinical research over the past eight years has succeeded in painting a more realistic picture of what the NIPT method can actually do, where its opportunities lie, but also its methodological limitations. This also makes it possible to draw a comparison of the value of NIPT with the standard method "combined NT test", which has been established at this point, that better reflects the real conditions in everyday life.


To shape advanced engineering materials, many unconventional machining processes have been developed. Electrical discharge machining is such an unconventional machining process which is very popular nowadays but it is limited by poor material removal efficiency. Electrical arc machining is another unconventional machining process which is quite similar to electrical discharge machining and is now gaining attention from research fraternity due to its high material removal efficiency. In the present research, an innovative unconventional machining process known as vibration-assisted electrical arc machining has been developed. The performance of vibration-assisted electrical arc machining has been evaluated during machining of Al–B4C metal matrix composite by considering peak current, flushing velocity of dielectric and tool vibrations as input control factors. The quality characteristics considered were material removal rate, tool wear rate, relative electrode wear rate and surface roughness. It has been observed that vibration-assisted electrical arc machining results in approximately 3000% more material removal rate as compared to conventional electrical discharge machining during machining of Al–B4C metal matrix composite. The effects of various input control factors on output parameters have also been discussed. Further modelling and optimization of the process parameters has also been done by artificial intelligence approach.

Hydrolysis of lactose with β-galactosidase is one of the most promising biotechnological applications in the food industry because of it is use in the production of low lactose dairy products. Acid whey samples were collected from the dairy pilot plant at the University of Jordan, Faculty of Agriculture. β-Galactosidase enzyme from Kluyveromyces lactis with initial activity of 3000 LAU/ml was immobilized in a sodium alginate and used for acid whey hydrolysis in fluidized bed reactor. Optimization parameters of lactose hydrolysis were (12 and 24% v/v enzyme concentration), (10 and 20 ml/mint flow rate). The process reaction was done at a temperature of 37 C o and 6.5 pH. Lactose hydrolysis of 81% and 85% were obtained during 6 h of incubation for 12 and 24% v/v enzyme concentration at flow rate of 10 ml/min.


This study aimed to use nine culture filtrates of algal strains (Nostoc muscorum, Anabaena flos aquae, Anabaena oryzae, Chlorella vulgaris, Wollea saccata, Phormedium fragile, Oscillatoria sp., Nostoc humifusum and Spirulina platensis), Azolla pinnata aqueous extract filtrate (1:2 w/v) and compost watery extract filtrate (1:5 w/v) in controlling the population of the root knot nematode, Meloidogyne incognita in cucumber under both laboratory and greenhouse conditions. Laboratory experiment revealed that high juvenile mortality percentage occurred during all the exposure periods of all treatments, the best results were after 72 hr exposure. Only five cyanobacterial strains, namely, Spirulina platensis, Oscillatoria sp., Anabaena oryzae, Nostoc muscorum and Phormedium fragile, followed by compost watery extract, significantly increased juveniles mortality over 70% at the highest concentration of 1:10 (84.3, 80.4, 78.9, 75.4, 72.5 and 70.1%, respectively). Azolla pinnata aqueous extract filtrate achieved 69.8% at the same concentration while, Anabaena flos aquae and Chlorella vulgaris recorded the lowest effect on mortality percentage (52.1 and 40.1%, respectively) at the concentration of 1:10. In the greenhouse experiment, the combination of mixing five algal culture filtrates of S. platensis, Oscillatoria sp., A. oryzae, N. muscorum and P. fragile with A. pinnata aqueous extract filtrate and compost extract achieved the highest reduction in the number of the 2 nd stage juveniles in soil, the numbers of galls, developmental stages, females, egg masses, egg numbers/egg mass in roots of cucumber plants comparing with the individual treatment and the non treated control. In addition, all combinations significantly improved fresh weight of roots and shoots and increased the yield of cucumber plants. The combined treatment of mixed algal culture filtrates + A. pinnata aqueous extract filtrate + compost extract significantly enhanced the soil biological activity in terms of total bacterial count, total cyanobacterial count, CO2 evolution, dehydrogenase and nitrogenase activities as well as the soil available nitrogen forms (NH4 + , NO3 -and NO2 -), available phosphorus and potassium over the control and resulting in soil electrical conductivity (EC) and soil pH reduction. It could be recommended that application of bioorganic agents as nematicidal against root knot nematode in cucumber is preferable in order to reduce the soil and plant polluting chemical nematicides.


In this paper the following result is established: a Jordan curve T in the extended plane C is a quasicircle if and only if there is a K, 1 .< K < ¿*>, such that, given ordered triples z , z , z and w , w-, w of points on T, there exists a X-quasiconformal mapping h of C onto itself with h(Y) = F and 7z(z .) = w. for / = 1, 2, 3. Notation and terminology. For 1 < K < oo we denote by Q the family of all K-qua si conformai mappings of the extended complex plane C onto itself. A Jordan curve F in C is said to be a quasicircle if, for some K, there is a map / in Q" such that f(V) is a euclidean circle. We say that QK is triply-transitive on a set A in C if, given ordered triples z , z , z and w., w , w of points in A, there is a map g in g" such that g(A) = A and g(z.) = w. fot j 1, 2, 3. Suppose that T is a Jordan curve in C and that Q is triply-transitive on T. If h belongs to Q,. , it is clear that Q _, is triply-transitive on 6 ^Kl' ^KJK * ' r. = Mr). Since Q. is precisely the class of Moebius transformations of C onto itself and since Q. is triply-transitive on circles and straight lines, it follows from the preceding remark that, given a quasicircle T in C, there exists a K such that Q" is triply-transitive on T. It is the purpose of this note to show that this property characterizes quasicircles. The motivation for this result is found in the following observation. Remark. If Q is triply-transitive on the Jordan curve V in C, then T is a circle or straight line. Assuming, as we clearly may, that the points 0, 1 and <x> belong to T, we demonstrate that T = Tg = R U i°°|. Let / be the finite subarc of T with endpoints 0 and 1. We show that / = /", the closed unit interval on the real axis.

The periodic calibration and testing of acoustic sensors, often involve extensive measurements in acoustic tanks. These are usually small facilities whose boundaries are covered with phono-absorption material to suppress reflections. The characteristics of such tanks are defined by the design of absorption planes and the choice of phono-absorption material. Since these characteristics are fixed, an acoustic tank may suppress reflections only for a certain frequency range and setup of the acoustic sensors within the tank, thereby limiting the applications supported by the tank. In this paper, we describe a novel design of an acoustic tank whose absorption characteristics are made adjustable. Inspired by Origami paper folding, this is achieved by changing the shape of the absorption plates with a single degree of freedom. Performing channel estimation between a projector and hydrophone for a required frequency range, the adjustment of the plates involves an iterative genetic-based optimization that finds the best Pareto front to maximize reflection mitigation. We report results from a prototype we contracted that shows a fast convergence of the tank to the best reflection suppression for frequency ranges of 20–30kHz and 35–40kHz. The outcome is an acoustic tank that adapts to various tested frequency ranges and setup of sensors, and can thus improve productivity of acoustic sensor calibration and testing in an efficient manner.


Terms of T. ovis infective eggs are differed in spring, summer and autumn at the pastures of the Moscow Region. Particularly development of eggs in April, June and August occurred over 49; 30 and 20 days respectively. One recorded varied egg counts in faeces in different months; for example those indices in April, June and September were 1,6; 9,1 and 20,8% respectively.


Fortran computer programs have been written for determining a geodesic path on an arbitrary surface of revolution. For this geodesic path on the surface, the corresponding payout-eye locations are calculated so that a machine wi.ll lay the filament along this geodesic path. Mandrel geometry and eye clearance are considered in locating the payout eye. The output of the program i s a listing of points along the surface and the corresponding payout-eye positions. This information i s then processed by an APT postprocessor to produce a punched tape for a numerically control led filament winder.

Firstly, all component elements of the hydraulic control system were confirmed after analyzing the structural characteristics and functions of the robots. Secondly,on the basis of working principle and process of every component element,a hydraulic system circuit was designed for the robot and the achieving process of every component element was analyzed. Last,the PLC control system and the electro-hydraulic servo control system were respectively devised. On the basis of transfer functions of all component elements,the whole transfer function of the system was built. It provides a theoretical foundation for component element selecting and circuit simulation.


Femtosecond transient absorption spectroscopy at 77 K was used to study excitation energy transfer processes in the reconstituted (r-)Lhca1 subunit of the peripheral light-harvesting antenna complex LHCI-730 of Photosystem I from higher plants. Under selective excitation of chlorophyll (Chl) b at 645 nm with 200 fs laser pulses, two energy transfer processes from Chl b to spectral forms of Chl a with lifetimes of 500 fs and 2.8 ps are induced. The subpicosecond phase reflects the energy transfer between closely located Chl b and Chl a molecules. Excitation at 670 nm induces a similar ultrafast process of energy transfer between neighboring Chl a molecules with a lifetime of 300 fs. The kinetic processes with the lifetime of 3−4 ps indicate an excitation equilibration among pools of Chl b and Chl a in the r-Lhca1, which involves the longest-wavelength spectral form of Chl a at 684 nm. This is in contrast to the Lhca4 subunit of the LHCI-730 heterodimer, which binds the longest-wavelength (red) pigments abs...

Stoichiometric Al-bearing ferrites[AlxFe3-xO4 (x=0.05–0.46)] are formed by a transformation reaction from γ-FeOOH in an aqueous suspension. The transformation reaction proceeds in a suspension containing γ-FeOOH, Fe(II) and Al ions without oxidation at 25°C and a pH of 9.5–11.0.


We investigate the acceleration process of particles in core-collapse supernova remnants (SNRs) propagating in the circumstellar medium with the Parker-spiral magnetic field, current sheet, and wind termination shock (WTS). Wolf-Rayet (WR) stars are considered in this work as progenitors of supernovae. Test particle simulations are performed to reveal the particle motion between the SNR shock and WTS and attainable maximum energy without magnetic field amplification in the upstream region, where the magnetic field strength and rotation period expected from observations of WR stars are used. We show that particles can experience the cyclic motion between the SNR shock and WTS until the SNR shock collides with the WTS. Particles are accelerated at the SNR shock and WTS again and again and the attainable maximum energy can exceed the maximum energy limited by escape from core-collapse SNRs.


The Fibonacci sequence can be obtained by drawing diagonals in Pascal's triangle, and from this, we can read the Lucas identity. An investigation on the behavior of certain kinds of other diagonals inside Pascal's triangle identifies a new family of recursive sequences: the k-Padovan sequences. This family both contains the Fibonacci and the Padovan sequences. A general binomial identity for k-Padovan sequences which extends both the well-known Lucas identity and the less known Padovan identity is shown


A tomato genomic clone has been identified which encodes histone H1. The deduced polypeptide is 287 amino acids in length, and exhibits the tripartite organization typical of histones H1. The central globular domain is highly similar to those regions from other H1 molecules, and the carboxyl-terminal domain contains a repeating hexapeptide motif, variants of which are conserved among H1 molecules. RNA gel blotting revealed that histone H1 mRNA is expressed at higher levels in organs which contain meristematic tissue and/or which have a high proportion of actively cycling cells. DNA gel blotting and dot-blot hybridization studies revealed that histone H1 in tomato is encoded by a small gene family. By employing the polymerase chain reaction on genomic DNA and on cDNA, it was determined that the gene is interrupted by an intron. The location and approximate length of the intron are conserved in both the tomato and Arabidopsis genes, with the intron separating the 'nose' region (encoded by exon 1) from the central globular domain (exon 2). The promoter region was found to contain several conserved sequence motifs which likely participate in the regulation of the gene.


Despite trends to consider film in the context of international relations, there has been very little real focus on how filmic sources can assist the understanding of war and peace. There is merit in analysing film in its own right; however, beyond this it can be a useful device for teaching and researching particular wars and aspects of them, as well as the relationship of film to war in general. This is demonstrated here by reference to the films about the Yugoslav War of the 1990s. However, exploring the detail of combat or cause or social impact in a particular conflict is not the only role film can play in teaching or research strategies. It is within the power of the moving image medium to explore the very essence and character of both a particular war and the very nature of war itself. This is shown to be the case with Francis Ford Coppola's Apocalypse Now, where the constant tussle between escalation and ethics, which underpins the conceptual frames of strategy, relating ends and means, is evident. War ceases to be war if the restraints are removed. When they are, the 'river of escalation' leads into the dark-hearted loss of soul, the critical loss of political perspective and purpose and the apocalypse of futility.


Studies on permeation through membranes have attracted attention during the last few decades because of the various applications of membranes in our day today life. Studies on Bulk liquid membranes (BLM). Emulsion liquid membranes (ELM) Supported liquid membranes (SLM) all have led to wonderful applications in technology and biology. An attempt is being made to throw light on the applications these liquid membranes in various biological fields viz facilitated transfer controlled release of drugs and all pharmaceutical applications.


We report the occurrence of Hipposideros ater Templeton, 1848 for the first time from Andhra Pradesh, India and describe a new subspecies collected from the Nallamala Hills, Eastern Ghats. The new subspecies has been compared with its nearest allies and it differs from the known subspecies H. a. ater and H. a. nicobarulae in having narrower palate, smaller braincase and U-shaped anterior margin of mesopterygoid.


Background: The function of Notch signaling in murine neural crest–derived cell lineages in vivo was examined. Results: Conditional gain (Wnt1Cre;RosaNotch) or loss (Wnt1Cre;RBP‐Jf/f) of Notch signaling in neural crest cells (NCCs) in vivo results in craniofacial, cardiac, and trunk abnormalities. Severe craniofacial malformations are apparent in Wnt1Cre;RosaNotch embryos, while less severe skull abnormalities are evident in Wnt1Cre;RBP‐Jf/f mice. Deficient cardiac neural crest migration, resulting in cardiac outflow tract malformations, occurs with increased or decreased Notch signaling in NCCs. Smooth muscle cell differentiation also is impaired in pharyngeal NCC derivatives in both Wnt1Cre;RosaNotch and Wnt1Cre;RBP‐Jf/f embryos. Neurogenesis is absent and gliogenesis is increased in the dorsal root ganglia of Wnt1Cre;RosaNotch embryos, while neurogenesis is increased and gliogenesis is decreased in Wnt1Cre;RBP‐Jf/f embryos. Conclusions: Together, these studies demonstrate essential cell‐autonomous roles for appropriate levels of Notch signaling during NCC migration, proliferation, and differentiation with critical implications in craniofacial, cardiac, and neurogenic development and disease.

Variable frequency drives (VFD) are widely used in industrial facilities, however, dynamic models for VFD-motor systems suitable for power system dynamic studies are not available. In this paper, a generic VFD-motor system modeling technique is proposed for the case that VFDs are able to ride through the fault. To illustrate the proposed technique, a dynamic model for a low voltage 6-pulse voltage source inverter (VSI) based drive and induction motor system with voltage per Hz control is created. To verify the accuracy of the developed dynamic model, a case study is conducted using a sample VFD-motor system, both derived dynamic model and detailed switching model for the same system are simulated using Matlab/Simulink, and their dynamic responses are compared. It is found that there are good agreements between the two models, and thus the accuracy of the developed dynamic model is verified. For the case that VFDs will trip out of lines, a VFD trip characteristic curve is proposed, and a simple screening procedure is recommended for evaluating whether the VFD-motor system shall remain in service or trip out of lines in power systems dynamic studies.


We investigate AdS3/CFT2 correspondence in three dimensional supergravity. We construct a current for general coordinate invariance and that for local supersymmetry via covariant approach. Hamiltonian and supercharge are well defined in terms of vielbein and spin connection. After discussing asymptotic supersymmetry group at the boundary of AdS3 geometry, we show that there exist a direct product of Virasoro algebras at the boundary. We also show that one of them is extended to super Virasoro algebra.


Sustainable hydroelectric power development requires protection and conservation of upstream catchments. An interesting case in this regard is the fact that the Government of Ethiopia is constructing Africa's largest hydroelectric power dam, the Grand Ethiopian Renaissance Dam (GERD), on the Blue Nile River while delivering in the same time tracts of land for commercial farming in the closer upper catchments. The dam has an estimated impounding capacity of 74 billion m3 (due completion in 2017). Considering these investments, it is necessary to determine the effects of the commercial farms on peak discharge and sediment in the surrounding of the hydroelectric power dam. Accordingly, this field survey was conducted from February to August 2015 on 20 ephemeral streams in Dangure district so as to compare peak discharges between 5-20 km2 catchments draining commercial farmland and others draining land under traditional management. Besides, socio-economic data was collected from 385 households from the study areas. We measured channel characteristics and applied the empirical Manning equation. We presented comparative results on peak discharge among commercial and conventional farming areas, forest, and woodland areas. Results indicate that there is a high rate of deforestation, erosion, stream incision, and gully formation in areas where commercial farming is being practiced. The absence of conservation activities in commercial farmlands contributes to the sediment load that is hazardous to the downstream water body and the livelihood of local people. Failure to shift the livelihood of local people to sustainable land use alternatives contributed to


Hegel' opinion of politics concentrates on his theory about "real " "reasonableness" and their relation. Although considered conservative, the theory was not to prettify the existing political system in Prussia. In fact, it expressed the political demands of the German Capitalists with those obscure philosophy words, which reflected the dual peculiarities of German Capitalism.

To obtain an optimal method for image enhancement of GF-2 forestry area data, six frequently-used methods were analyzed:Brovey transformation; hue, saturation, and value (HSV) transformation; Principle Component (PC) spectral sharpening; high pass filter (HPF) spectral sharpening; Gram-Schmidt spectral sharpening; and Pansharp transformation. Qualitative and quantitative analyses were used to assess the effect and quality of the fusion images. Indexes include mean, average gradient, high-frequency information integration, correlation index, entropy index and second moment index. Among them, correlation index and second moment index were calculate by ENVI, other indexes were all by Matlab. Furthermore, to access an appropriate fusion method for GF-2 forestland data extraction, fusion images were classified by performance of fusion methods at two information extraction levels based on an object-oriented classification method. All the transformations used the same parameter and methods on each level, and use the same samples to classify and accuracy check. Results showed that correlation index and high-frequency information integration of HSV transformation could reach 0.823 and 0.570, respectively. In addition, the entropy index and second moment index could improved 25% and 50% compared to original multiple image, respectively. It had a better visual effect with obvious enhanced clarity and texture features. For classification experiments, HSV and Brovey transformations had their own superiority for the extraction of different classes with the HSV transformation having the highest overall classification accuracy of 85.1% and the Brovey transformation having the highest accuracy on the second level of 75.7%. The other four methods had different advantages for quality and information extraction of the fusion images. Thus, the final selection of fusion methods should consider practical forestry application and image information which could provide a reference for GF-2 images to be applied on a large scale in forested areas.


The modeling of networked control system is the foundation of the analysis, design, and simulation. In this paper, the main drawbacks of the current literatures related to networked control system are discussed. Meanwhile, a uniform model is developed based on the linear time-invariable plant model, including the situations in which the network-induced delays are shorter or longer than sampling periods. Considering the dynamic features of controller, noise and packets dropout, the uniform model is built in the discrete stochastic formation, and then many conveniences are presented for the controller design and stability analysis


The appearance of cultural heritage artefact is perceived by the eyes of an observer. The perception is caused by absorption, scattering and reflection of light. For this process, not only the threedimensional form but also the materials the object consists of play an important role. To provide a faithful impression, both aspects, shape as well as appearance, have to be acquired, stored and rendered. However, conventional techniques, such as pictures or (possibly textured) geometric 3D models, are not sufficient for that task. Therefore, our research deals with devices and representations that allow for a faithful digital reproduction, a virtual surrogate. The presented technique facilitates the mostly automatic acquisition and processing of small to medium-sized opaque artefacts, the interactive inspection of the digitized objects and the fast and progressive transmission over the internet.

The permanent photorefractive effect induced in Bi12 SiO20 crystals by intense nano and picosecond pulses shows a long rise-time (in the range 10 - 100 ms), and a diffraction efficiency limited to values ~ 5.10-4.(1)(2) These limitations are connected with the existence of transient effects characteristic of intense and fast excitations.


The ultimate goal of this work is to facilitate the design of gas turbine engine particle separators by reducing the computational expense to accurately simulate the fluid flow and particle motion inside the separator. It has been well-documented that particle ingestion yields many detrimental impacts for gas turbine engines. This ingestion is of concern for operation in environments where dust, ash, or ice persist. The consequences of ice particle ingestion can range from surface-wear abrasion to engine power loss. Ice particles are chosen for this study because of their relevance to civil aviation. It is known that sufficiently small particles, characterized by small particle response times (τp), closely follow the fluid trajectory whereas large particles deviate from the streamlines. The behavior of small particles hints at a method for larger particle trajectories because the higher order terms (HOT) in the asymptotic particle acceleration solution can be shown to be O(τp). By explicitly considering τp, these HOT can be derived. Rather than manually deriving these terms, this work chooses to implicitly derive them using machine learning (ML). Inertial particle separators are devices designed to remove particles from the engine intake flow. Particle separators contribute to both elongating the lifespan and promoting safer operation of aviation gas turbine engines. Complex flows, such as flow through a particle separator, naturally have rotation and strain present throughout the flow field. This study attempts to understand if the motion of particles within rotational and strained canonical flows can be accurately predicted using supervised ML. This report suggests that preprocessing the ML training data to the fluid streamline coordinates can improve model training. Furthermore, this work provides some guidelines for applying ML, particularly deep feed-forward neural networks, with physics driven multiphase flow data. Additionally, the ML model is able to predict the particle accelerations in the fully rotational and irrotational canonical laminar flows quite well. For combined flows with rotation and strain, however, the model struggles to predict the particle accelerations.


The General Beale Pilot Project serves as a case study for the use of areawide monitoring and treatment programs for glassy-winged sharpshooter (GWSS), Homalodisca vitripennis (Germar), and monitoring and roguing programs for grapevines infected with Xylella fastidiosa, to achieve regional management of Pierce's disease. The Project is located in southeast Kern County, CA, and contains ~2,800 ha of citrus and grapevines grown within approximately 50 km2. For nearly 20 yr, an average of 470 traps have been used to monitor GWSS populations regionally by the California Department of Food and Agriculture, and to inform coordinated, areawide treatments by the USDA-APHIS Areawide Treatment Program to overwintering GWSS in citrus. Grape growers were responsible for treating their own vineyards, and for the roguing of infected grapevines based on surveys provided by the University of California. Herein, we provide a history of the General Beale Pilot Project, broken down into six eras based on levels of Project success, which incorporate data on GWSS captures, pesticide use, and disease incidence. We describe patterns of success related to the regional coordination of effective treatment and roguing programs that can be used by grape and neighboring citrus growers for areawide management of Pierce's disease. We conclude by describing current and future challenges for Pierce's disease management, including pesticide availability and resistance, GWSS refuges, the inability to detect and rogue infected vines in the year they become infected, and the sustainability of voluntary programs that rely on public funding.

This paper reviews the NMR methods to determine the absolute stereochemistry of organic compounds.The methods are classified into two types in terms of the principle in this paper. One applies magnetic anisotropy effect of phenyl or other aryl groups, such as Mosher method, methods utilizing MPA or other AMAs chiral reagents. The other type applies glycosylation shift effects due to glycosylate reactions, such as tetra O benzoyl glucosylation method and fucofuranoside method. This review deals with the principle, the determining process, the advantages and disadvantages of each mothod.


Introduction: Joint IODP-ICDP Expedition 364 drilled an offshore hole, M0077A (Figure 1), into the peak ring of the Chicxulub impact structure in Mexico [1]. Prior to drilling, a suite of seismic data were acquired in 1996 and 2005 [2, 3] that imaged the peak ring and indicated it was formed from rocks with a low seismic velocity [4, 5]. As part of a site survey, three crossing lines through the proposed drill site were acquired in 2005. Full-waveform inversion (FWI) of these three lines was performed to obtain highresolution models of seismic velocity across the peak ring [6], to help distinguish between models of peakring formation. The FWI results confirmed that the peak ring was formed from low-velocity rocks (3.9-4.5 km/s), and also identified the presense of a 100to 150-m thick low-velocity zone (3-3.2 km/s) (LVZ, light blue in Figure 1) in the uppermost peak ring, that was interpreted to be impact breccia [6]. Drilling revealed that the Chicxulub peak ring is formed from a ~130-m of suevite and impact melt rock that lies above uplifted, shocked, felsic basement (Figure 1). Wireline logging and VSP data confirmed that the suevite in the upperost peak ring has a lower velocity (~3 km/s) than the Paleocene sediments (3.5-4.0 km/s) above and basement below, and that the felsic basement itself has an unexpectedly low seismic velocity (3.5-4.8 km/s) [1].


The study aimed to formulate a pure herbal shampoo and to evaluate and compare its physicochemical properties with the marketed synthetic and herbal shampoos. The herbal shampoo was formulated by adding the extracts of Acacia concinna, Sapindus mukorossi, Phyllanthus emblica, Ziziphus spina-Christi and Citrus aurantifolia in different proportions to a 10% aqueous gelatin solution. Small amount of methyl paraben was added as a preservative and pH was adjusted with citric acid. Several tests such as visual inspection, pH, wetting time, % Of solid contents, foam volume and stability, surface tension, detergency, dirt dispersion etc, were performed to determine the physicochemical properties of both prepared and marketed shampoos. The formulated herbal shampoo was also evaluated for conditioning performance by administering a blind test to 20 student volunteers. The formulated herbal shampoo was clear and appealing.


Punishment is a critical aspect in evaluating the functioning of the state and the legitimacy of its authority. The main punishment in modern societies is imprisonment. What are prisons for? Whom are they meant to benefit? What are their effects? And, most importantly: can they be justified? Decades of empirical research have shown that doing nothing in response to crime has been shown to be just as effective (and considerably cheaper). If the ends are not achieved, the justifications are moot. This study considers the philosophical aftermath: Are we morally obliged to submit to institutions that don't work? What happens if we don't? Finally, this study considers the theoretical implications of the state getting out of the business of punishing by considering alternatives to state punishment in «First Nations communities in Canada as an example of a practice after the end of punishment.


But I am concerned with lX)ssible accomp lishments, not just easy ones. It seems to me that if Americans can be taught to think of their duties to the 'Hider corrmunity of which they are a part, and if their notion of com'llllility can be expanded to encompass our fragile planet's other inhabitants, basic and radical changes will take place. The task is two-fold: to restore our sense of reslX)nsi bility for our common life, and to expand our notion of the COIllllOn to include our fellow travelers on this blue-green ball.


Segmentation is an instrumental task in medical image analysis. In addition to existing manual, semi-automatic and automatic segmentation models, deep learning has been the niftiest machine learning technique in current research interests. However, none of the models or technique can escape from the overdependence on training data and user intervention. As a result, the use of computer-aided and learning algorithms have reported lackluster robustness in the presence of high anatomical disparity. In recognition of this, we have proposed a binary seeds auto-generation model to reduce the reliance on manually crafted priori information in deep learning. Then, we computed the reproducibility of the proposed model against manual segmentation using normal and osteoarthritic knee magnetic resonance image. In normal knee image, mean agreements of the proposed model and manual segmentation were $0.94 \pm 0.022$ and $0.83 \pm 0.028$ respectively. In osteoarthritic knee image, mean agreements of the proposed model and manual segmentation were $\mathbf{0.92}\pm\mathbf{0.051}$ and $\mathbf{0.79}\pm \mathbf{0.073}$ respectively. Pair t test showed that our method has better accuracy than manual segmentation in both cases (normal: $\text{P}=1.03\times 10^{-9}$; osteoarthritic: $\text{P}=4.94\times 10^{-8}$). Therefore, we can conclude the model is robust to be implemented as part of deep learning based segmentation framework.


The synthesis of 2-methyl benzoxazole by the reaction of 2-amino phenol and actic acid glacial.,The effects of phase transfer catalysis,the mole ratio of reactant and reaction temperature on the yield of product have been studied. The optimum condition has been determined by the method of orthogonal design.


Until about two years ago, routine processing of seismic reflection data was based on the common midpoint (CMP) stacking model. Large amounts of seismic data were moved through the computer (from tape to disc to memory, etc.) but rather simple computations were performed on the data (time shifts and additions with occasional convolutions). The large amounts of recorded data were reduced by factors of 12, 24, 30, 60 or more by common midpoint stacking prior to the computationally intensive process of migrating the reflection events to their true subsurface locations.


The research on the formation and dissociation of methane hydrate in porous media is very important for understanding the natural gas hydrate in permafrost regions. 10 times of the experiments were conducted to research the effect of the cooling process on the formation of methane hydrate within the coarse sand. And the results showed that the cooling process affected the formation of methane hydrate within the coarse sand very much; about 90% of the-methane hydrate had been formed before the temperature inside the pressure vessel decreased to 0℃ which meant that little methane hydrate was formed during the frozen process; and the slower the temperature decreased, the greater the converting rate from the water to the hydrate was. When the frozen sand began to melt, the formation of methane hydrate was observed.


Objective To clarify the role of Pyk2 in cell proliferation and apoptosis in Lovo rectal cancer cells in vitro.Methods Two sets of shRNA (short hairpin RNA which will be subsequently processed to siRNAs) expression plasmid vectors were used to transfect lovo cells separetely.The lovo cells and the cells transfecled with a non - targeting, negative shRNA expression plasmid were used as controls.The downregulation of the protein level and mRNA level was further confirmed by Western blotting and RT - PCR. The growth curve of lovo cells was studied by cell counting.The changes in apoptosis and cell cycle were derermined by flow cytometry. Results Cells transfected with one of the shRNA expression vectors obtained knockdown of pyk2,with a significantly lower apoptosis level.The number of cells in the S stage of cell cycle increased as cell count did.Conclusion Pyk2 elevates the apoptosis level of lovo cells and lowers their proliferation.


Abstract The purpose of this paper is to prove strong type inequalities with pairs of related weights for commutators of one-sided singular integrals (given by a Calderón-Zygmund kernel with support in (-∞, 0)) and the one-sided discrete square function. The estimate given by C. Segovia and J. L. Torrea is improved for these one-sided operators giving a wider class of weights for which the inequality holds.


Automating the conversion of human-readable HTML tables into machine-readable relational tables will enable end-user query processing of the millions of data tables found on the web. Theoretically sound and experimentally successful methods for index-based segmentation, extraction of category hierarchies, and construction of a canonical table suitable for direct input to a relational database are demonstrated on 200 heterogeneous web tables. The methods are scalable: the program generates the 198 Access compatible CSV files in ~0.1s per table (two tables could not be indexed).


We can obtain useful information by deploying large scale sensor networks in various situations. Security is also a major concern in sensor networks, and we need to establish pairwise keys between sensor nodes for secure communication. In this paper, we propose new pairwise key establishment mechanism based on clustering and polynomial sharing. In the mechanism, we divide the network field into clusters, and based on the polynomial-based key distribution mechanism we create bivariate Polynomials and assign unique polynomial to each cluster. Each pair of sensor nodes located in the same cluster can compute their own pairwise keys through assigned polynomial shares from the same polynomial. Also, in our proposed scheme, sensors, which are in each other`s transmission range and located in different clusters, can establish path key through their clusterheads. However, path key establishment can increase the network overhead. The number of the path keys and tine for path key establishment of our scheme depend on the number of sensors, cluster size, sensor density and sensor transmission range. The simulation result indicates that these schemes can achieve better performance if suitable conditions are met.


hort. This study alone reported on 272 single-docking, totally robotic techniques. Although there is an absence of tactile feedback with robotic technology, we have not found this to negatively impact on TME quality anecdotally. TME is actually a plane-based surgery, so tactile feedback is not much of a critical component to achieve a high-quality specimen. Instead, the technical advantages of robotic surgery, such as instruments that can bend and rotate, high-definition 3-dimensional vision, and surgeon-controlled multiarms, not only compensate for the lack of tactile feedback but also enable potentially better TME surgery. Unfortunately, we did not provide data on TME quality in this study because it was recorded only for the latter half period of our cohort, which was mostly complete/ nearly complete in both groups. In most centers, TME quality is not reported as part of synoptic reporting for rectal cancer. We agree with Foppa and Bergamaschi that this would be an important area for additional research. Although we have not reported on TME quality, we have provided good pathologic results in our study. We also reported on numerous validated metrics, such as degree of differentiation, TNM stage, number of lymph nodes harvested, and distal resection margin and provided a comparison both matched and unmatched in the robotic and laparoscopic TME subgroups. With regard to CRM, we only provided data on positivity (<2 mm) in the article because the actual width was recorded in the later period. We did not find a significantly decreased rate of CRM involvement, but it is important to note that CRM is only one of many variables that may influence cancer-specific survival. There were limitations to our study. Our study was not randomized, and for this reason we performed case matching to reduce the potential for selection bias. This was a singleinstitution study. The strength of our study was our large cohort, robust clinic–pathologic data with good follow-up, and good standardization of technique on single-docking totally robotic resection. Although we have not reported on TME quality in this study, we anticipate that in future studies we may be able to demonstrate oncologic histopathologic data. Our study was the first report of 5-year long-term survival analysis of only single-docking totally robotic surgery (other studies have reported on hybrid and dual docking). Our study was also the first to identify robotic procedure as a positive prognostic factor. However, we were not able to show superiority for robotic TME over laparoscopic TME, although there was a trend toward improved survival. We believe that this trend could have derived from a sum of subtle advantages of robotic rectal dissection that might not be able to be measured by ordinary clinical parameters, such as a lesser degree of tissue trauma to the tumor-bearing rectum with better exposure. The miracle machine, as termed by Foppa and Bergamaschi, often refers to a fictitious, mythical device with sensationalized powers. Robotic technology is far from that. Those who have expertise in robotic surgery understand that robotic surgery provides significant technical advantages in confined spaces and provides improved ease of procedure for the surgeon. Future evidence-based studies will evaluate whether the benefits of robotic rectal surgery will outweigh the costs.


like a rising river or information that is considered secret or a potential threat. Another meaning of "leak" involves loss, such as the loss of electric current because of faulty insulation. The American Heritage Dictionary says that "leak" is the path or place at which the loss occurs. In this paper, "leaky walls" are a threshold, constructed as a division and a simultaneous joint between a hope and a memory and between one home and another.

The Belt and Road Initiative has encouraged increasing Chinese enterprises in multinational investment and development in the Belt and Road countries. Differing from previous multinationalization, the Initiative requires the enterprises to take Corporate Social Responsibility (CSR) and profit pursuit as equal priorities in the very beginning. That is, the principle of achieving shared growth through discussion and collaboration consolidates the cooperation foundation. This differentiation could signify a new multinationalizing paradigm. For the purpose of revealing this paradigm, the authors construct a G-CAGE Framework. This paper demonstrates that: (1) Chinese enterprises in the Belt and Road countries take CSR as a prime consideration. (2) The enterprise's responsibility should differ along cultural, administrative, geographic, economic and green development distances. (3) Chinese enterprises are the main body for establishing a new development paradigm among the Belt and Road countries, and taking CSR strategically is the right way to achieve that.


A process for the preparation of a spray-dried food (267; protein, IS:& fat) based on
full-fat soya flour, dextrin-maltose mixture and hydrogenated groundnut oil and fortified
with DL-methionine and certain vitamins and minerals has been described. When packed in
air in sealed tin containers, the food was organoleptically acceptable at the end of 6 months'
storage at 37". The protein efficiency ratio (PER) of the food was 2.47 ; fortification of
the food with DL-methionine at a level of 4 g. per kg. markedly increased its PER to almost
the same level as that of a control milk food of similar composition. The overall growthpromoting
value of the product, with or without added methionine as also that of 3 : I blend
of the above foods with cane sugar was significantly higher than that of the milk food or
milk food-sugar blend. However, no significant differences were observed in the feed
efficiency ratios obtained for soya food (with or without added methionine) and milk
food. It may be concluded that in many developing regions where milk is in short
supply and soya-bean is readily available, the spray-dried food costing only about 4s. per kg.
and possessing an overall nutritive value comparable to that of a milk food of similar
composition can be manufactured on large scale and used for supplementary feeding of
weaned infants.

In Ukraine, the culture of contracting outsourcing services is not yet fully developed, which in turn leads to a fuzzy understanding of the responsibility of the parties to such relationships, and therefore the security of their partner cooperation in the domestic market. The purpose of the research is to develop the main provisions of the Contract on outsourcing services as a guarantee of the responsibility of the outsourcing company for violating the confidentiality, timeliness, completeness and quality of the work performed in order to ensure the economic security of the enterprise-customer of such services. The structure of the Model Agreement on outsourcing services (which is the most comprehensive, expanded and systematically provides the system of liability of the parties to the agreement) is proposed, as well as the conditions that reduce the risk of disclosure of information constituting confidential information and trade secrets in the course of the use of maintenance services accounting outsourcing company. The results of the research substantiated the expediency of conducting a number of organizational measures among the employees of the outsourcing company (getting acquainted with the clauses of the Agreement regarding the non-disclosure of commercial secrets, ranking the levels of access to customer information, etc.), which contributes to the maximum protection of all types of information and, accordingly, the quality of provision outsourcing services for the business efficiency. In general, the proposed instruments contribute to the precise regulation of partnership relationships when outsourcing to the development of a culture of drafting such agreements, which in turn leads to a clear understanding of the responsibilities of business parties, which is the foundation of the investment attractiveness of domestic business entities for the global community.


Tissue acidosis is an hallmark of inflammatory, ischemic and tumoral processes and although it remains uncertain whether there is a true cause-effect relation between acidosis and adverse clinical outcomes it remains a powerful marker of poor prognosis in critically ill patients. Dysregulation of host defence mechanisms and in particular of the immuno-inflammatory responses occurs during sepsis. Sepsis is always associated with acidosis conditions and is able to alter inflammatory mediators release and thus the immune response. Patients with severe sepsis and septic shock exhibit a complex metabolic pattern of acidosis at intensive care unit admission, caused predominantly by hyperchloremic acidosis, which was more pronounced in non survivors. In this study, conducted in vitro, we analyzed the effects of N-acetylcysteine (NAC), a molecule with antioxidant activity, during the inflammatory process, in acidosis conditions, in J774A.1 murine/macrophages stimulated with Lipopolysaccharide from E.coli (LPS). Our results show that NAC, in hyperchloremic acidosis conditions, reduces cyclooxygenase-2 (COX-2) and heat shock protein 70 (Hsp70) expression without significantly affecting changes in the constitutive isoform Heat shock protein 90β (Hsp90β) expression in LPS-treated macrophages . Our data report a reduced inflammatory response exerted by NAC in hyperchloremic acidosis conditions indicating that the use of NAC during inflammation further impairs immune response associated to acidosis associated disease, as septic shock.


Summary Serum thrombotic accelerator (STA) activity requires for its elaboration activation of HF, PTA, and Factor IX, but does not depend on platelets or any other recognized coagulation factor with the possible exception of Ca++. Although essential in the donor serum for formatioln of this thrombotic moiety, HF, PTA, and Factor IX need not be present in the recipient animal for thrombus formation to occur. STA activity is distinct from Ca++, HE, and PTA, and may not be identical with Factor IX; however, activatioln of HF appears to be the initial reaction required in the elaboration of this potent thrombotic agent that is distinct from thrombin and tissue thromboplastin.


OBJECTIVE
To evaluate the relationship between pelvic organ prolapse in Korean women and joint hypermobility, which suggests a metabolic collagen fiber abnormality.

STUDY DESIGN
Between March 1998 and March 2000, we investigated 55 patients with prolapse. The prevalence of joint hypermobility, by measuring finger extension angle, and the proportion of patients with joint hypermobility were measured in patients with pelvic organ prolapse and benign gynecologic patients (control group).

RESULTS
In middle-aged women (40-59 years), the average finger extension angles were higher in the POP group than in the control group (50.04 +/- 9.70 degrees vs. 39.50 +/- 12.19 degrees, respectively; P < .05), but in older women there was no significant difference between the two groups (42.84 +/- 13.05 degrees vs. 43.00 +/- 13.34 degrees, respectively; P > .05).

CONCLUSION
The prevalence of joint hypermobility was higher in the POP group and with advanced POP stage (III, IV) than in the control group and early POP stage (I, II). Our results suggest that intrinsic connective tissue abnormality is related to the development of pelvic organ prolapse. Further study involving more patients with pelvic organ prolapse is warranted, and molecular studies to determine the genetic basis of pelvic organ prolapse are also required to further elucidate this abnormality.

Educational applications have become complex enterprise web applications. During the design and development of this type of software we have realized the existing modeling approaches were not well suited for the modeling of JSF or ASP.NET MVC applications. This paper extends UML for the modeling of the presentation tier of enterprise applications based on JSF or ASP.NET MVC frameworks. Our main aim was to include navigational, structural and role-based access control (RBAC) elements for JSF/ASP.NET MVC applications in UML class and sequence diagrams built according to multitier patterns. Accordingly, our approach: (i) characterizes the navigational, structural and RBAC elements of JSF/ASP.NET MVC frameworks; (ii) does not define a proprietary notation but provides two platform-specific UML profiles that extend UML-WAE; (iii) is able to include any multitier, service-oriented architecture and security design-level pattern in the models; (iv) provides models whose semantics can be directly translated into code; and therefore, (v) decouples code maintenance from specific tools. This approach has been successfully used in the design of a complex e-learning web application deployed by our research group.


Once again Carol Pemberton has brought Lowell Mason to life with her graceful prose. Her biography of Mason was published in 1985. This bio-bibliography could be seen as a continuation of the previous work. It is divided into three sections, the first being a brief biographical outline of Mason's life. The second section is devoted to a detailed list of works authored by Mason. . The third contains a list of works about him. Pemberton announced in the preface that she chose to exclude music and biographical dictionaries and encyclopedias from this writing simply because most readers would seek out those forms of references without suggestion from any other source.


Geospace plasma simulations have progressed toward more realistic descriptions of the solar wind–magnetosphere interaction from magnetohydrodynamic to hybrid ion‐kinetic, such as the state‐of‐the‐art Vlasiator model. Despite computational advances, electron scales have been out of reach in a global setting. eVlasiator, a novel Vlasiator submodule, shows for the first time how electromagnetic fields driven by global hybrid‐ion kinetics influence electrons, resulting in kinetic signatures. We analyze simulated electron distributions associated with reconnection sites and compare them with Magnetospheric Multiscale (MMS) spacecraft observations. Comparison with MMS shows that key electron features, such as reconnection inflows, heated outflows, flat‐top distributions, and bidirectional streaming, are in remarkable agreement. Thus, we show that many reconnection‐related features can be reproduced despite strongly truncated electron physics and an ion‐scale spatial resolution. Ion‐scale dynamics and ion‐driven magnetic fields are shown to be significantly responsible for the environment that produces electron dynamics observed by spacecraft in near‐Earth plasmas.

A move towards a circular economy will require fundamental changes in the way products and services are designed. However, tools for design in the  context of the circular economy  mostly have a narrow product or service focus without acknowledging the role of addressing behaviors and changing practices. This paper presents the results of an exploratory study investigating to what extent circular design tools consider and integrate aspects related to consumption and consumers. Using five circular tools publicly available, the research team analyzed how they address three aspects: circular consumer behaviors, consumer acceptance factors and conditions for adoption. Our analysis shows that although some of the tools acknowledge the need to gather insights around consumption and consumers, they do not address such aspects in detail. When the tools considered consumer aspects, they did so by acknowledging circular consumer behaviors. Rent and rebuy are the most frequently mentioned behaviors, while remunerate, retain and renounce are absent from the tools. Other behaviors such as receive, ritualize, regard, revalue, resell and relinquish are mentioned only once. The tools' lack of consideration of acceptance factors and contextual conditions is slightly surprising, as most of them advocate for a human-centered approach to product development. Existing circular design tools could thus benefit from integrating concepts and frameworks from fields such as design for sustainable behavior and practice-oriented design.


The title compound, C16H10N4O2, is an organic red pigment utilized for hydrogen gas sensors. The centrosymmetric diketopyrrolopyrrole is nearly planar and is linked to four neighbouring molecules via N—H⋯N hydrogen bonds to form a two-dimensional network in the (201) plane.


The tethered system, which composed with a mother ship and satellite connected with tether, is an example of recent satellites. In the analysis and modeling of tether, large deformation and large displacements must be considered. The Absolute Nodal Coordinate Formulation can describe the motion of tether. In the modeling method, internal damping and fluid resistance are not considered, and the identification for such parameters is still problem to be solved. In this study, the effect of damping and fluid resistance based on strain energy and drag equation are formulated while considering a parameter identification method. These parameter and number of elements are identified by the experiment at the same time. In order to verify the modeling method, an example of swing-up control using a genetic algorithm is performed in simulation and experiment. Validity of model and availability of motion control based on multibody dynamics are shown comparison between experiment and simulation.


This is the Second Workshop on Improving Non-English Web Searching (iNEWS'08) held in conjunction with the 17th ACM Conference on Information and Knowledge Management (CIKM 2008) in Napa Valley, California, on 30 October 2008. The First iNEWS'07 Workshop took place in Amsterdam (The Netherlands) in conjunction with the 30th Annual International ACM SIGIR Conference (SIGIR'07). The workshop aims at bringing together researchers interested in the issues surrounding non-English web searching.

Nowadays, over 60% of Internet users are non-English speakers and the number of non-English speaking Internet users is growing faster than the English speaking. Recent studies showed that non-English queries and unclassifiable queries have nearly tripled since 1997. Most search engines were originally engineered for English. These do not take into full account the specifics of non-English languages, such as, inflectional semantics nor diacritics or capitalization.

The main conclusion from the literature is that searching using non-English and non-Latin based queries results in lower retrieval success and requires additional user effort so as to achieve acceptable satisfaction levels. Furthermore, international search engines, like MSN Live, Google and Yahoo, are relatively weaker with monolingual non-English queries.

New tools and resources are needed to support researchers in non-English retrieval, new methodologies need to be proposed which will help the identification of problems in existing search engines and new teaching strategies should be formed aiding users to become more efficient in formulating their queries. Foremost, research in non-English web search should provide an incentive to search engines to improve the retrieval performance of their engines for non-English languages.

Taking into account these needs, the main objectives of this workshop are the proposal of techniques and the evaluation of tools which improve the effectiveness of the existing search engines. This way, the specific aims of the workshop have been to:
Evaluate search engines in non-English queries and measure the additional user effort.
Define methodologies for evaluating the effectiveness of search engines in non-English queries.
Study the user query patterns in non-English Web retrieval.
Identify the factors that influence utilization of search engines in a multicultural world.
Propose extensions to the search engines to improve non-English Web retrieval.
Propose teaching strategies for helping users improve their searching behavior.
Identify how standard IR techniques (Indexing, Query representation, Query reformulation, etc) can be adapted in Web retrieval for non-English languages.
Discuss the application of natural language processing techniques for non-English Web IR.

In response to our call, 27 papers were submitted. Each paper was reviewed by three expert referees in a blind review process. 10 full papers and 7 short papers were selected for oral or poster presentations and appear in these proceedings.

For the determination of the directivity, the following steps are required: • detection of the first arriving sound, • time shift of the impulse response, • time windowing for artifact removal, • regularized division to improve signal-to-noise ratio.


The present study aimed to investigate the increasing solidification rate during directional solidification developed from in situ composites of M7C3/austenite eutectic, to in situ composites with a small portion of dendrites, and to partial in situ composites with equiaxed structures. M7C3 fibre aligned along the solidified direction in the in situ composites; however, its orientation and shape became irregular among the dendrites. In situ composite structure has higher tensile strength than partial in situ composite or equiaxed material. Crack initiation in the fibre occurred because the fibre could not accommodate the deformation of the matrix under tensile stress. The tensile fracture was caused by both crack initiations in the M7C3 fibre or at the randomly oriented particles, and the crack propagation to matrix.


The prohibitive costs of commercial test equipment for making fast and accurate pulsed phase and amplitude measurements at X-Band result in decreased productivity due to shortages of shared equipment across the test laboratory. In addition, most current set-ups rely on the use of pulsed power heads which do not allow for the measurement of phase thereby limiting the flexibility of available measurements. In this paper, we investigate less expensive in-house designed instrumentation based upon commercial satellite down converters and widely available logarithmic detector amplifiers and phase detectors. The techniques are used to measure X-Band pulses with widths of 50 ns to 10's of usec. We expect a dynamic range of 30-40 dB with accuracies of better than +/- 0.1 dB and +/- 1 degree of phase. We show preliminary results of the built and tested modules. Block diagrams of the down conversion scheme, and the architecture of a multi-signal X-band RF monitor and measurement system is illustrated. Measured results, and possible modifications and upgrades are presented.

RDF knowledge graphs have received more attention in recent years. Many graph similarity search approaches are proposed to help users get the desired knowledge. However, few of them consider storage architecture and semantic similarity search together. We believe that a complete query engine requires not only an efficient search approach, but also a reliable storage architecture to support. In this paper, we design a semantic-based graph similarity search engine SimG with carefully designed architecture and data structures over an RDF Knowledge graph, which can quickly get the best k answers even given a simplified queries (e.g., Basic Graph Pattern (BGP)) by users. The outstanding features of SimG are as follows: (1) To improve RDF data management efficiency and reduce storage overhead, we first divide the RDF knowledge graph into multiple topic graphs based on the type similarity model. Then we store these topic graphs in a distributed manner(e.g., all topic-graphs are managed and maintained independently). (2) In order to manage topic graphs efficiently, we utilize the adjacency list as the fundamental data structure to store each topic graph. Moreover, we design a skip list based index to accelerate the data accessing. On the top of this topic graph storage, we implement several basic APIs such as access, add, delete and update to support the following semantic query approach. (3) The semantic similarity query module is deployed on the topic graph storage, which returns topk answers by considering the semantic feature based on the APIs implemented above. Finally, extensive experiments on our query algorithm and storage architecture confirm the effectiveness and efficiency of SimG.
