The Carpathian-Pannonian Region (CPR) hosts
one of the major Cainozoic volcanic provinces of
Europe extending in space over 6 eastern European
countries.The lithospheric evolution of this large
area governed by large-scale asthenospheric
processes is recorded by products of volcanic
activity occurred during a time interval of more
than 21 million years. According to their surface
occurrence areas, ages and composition the
Neogene volcanics of CPR were systematized in
three main groups: 1) mostly explosive products
of felsic magmas generated at the beginning of
volcanism in the whole CPR and in their particular
occurrence areas (21-12 Ma) developed in the
actual intra-Carpathian Pannonian Basin, 2) mostly
intermediate calc-alkaline rocks emplaced in both
the intra-Carpathian areas and along the arcuate
Carpathian fold-and-thrust belt, and 3) Na- and K-
alkaline and ultra-alkaline products clustered in a
number of monogenetic volcanic fields across the
whole intra-Carpathian realm developed in the final
stages of volcanic activity of the CPR as a whole
and of their particular occurrence areas. The ca.
160 km long Călimani-Gurghiu-Harghita volcanic
range (CGH) developed as part of the intermediate
calc-alkaline volcanism closely related in space
with the fold-and-thrust belt of the Carpathians,
representing the south-eastern segment of the CPR.
Although its map view and general petrochemical
and volcanological characteristics are quite similar
with those of other segments of the orogene belt-
tied calc-alkaline volcanic segments, at a closer
look CGH displays a number of unique features.
The time-space evolution of CGH is particular
not only in that it is the youngest (10.5 to < 0.05
Ma) dominantly calc-alkaline segment in CPR
but also it shows a transient character. Unlike
other segments along which volcanism occurred
simultaneously forming true subduction-related
400 to 800 km long volcanic fronts which were
stable in time for millions of year, in CGH
volcanic activity migrated continuously along the
range from NW to SE. So, during any given 1 Ma
time interval active volcanism was restricted to
very limited areas and to just a few active volcanic
centers. The along-range shift of volcanic foci
was concurrent with progressively lower volumes
of magma erupted and decreasing magma output
rates. As a result, gradually lower-volume and
less complex volcanic edifices were built up.
Moreover, at the range-ending and youngest South
Harghita sub-segment, magma compositions
gradually changed from normal calc-alkaline to
high-K calc-alkaline and shoshonitic, and adakitic
features emerged at the end of volcanic activity,
after a time gap of 0.5 Ma. This marks a major
geodynamic event in the development of the East
Carpathians themselves. During the transient
volcanism of CGH, edifices of varying volume and
complexity were built up forming a row of tightly-
packed adjoining stratovolcanoes/composite
volcanoes whose peripheral volcaniclastic aprons
complexly juxtaposed, overlapped and merged
with each other. The largest ones (Călimani
caldera, and Fâncel-Lăpusna) developed until
caldera stage. Some of them (Rusca-Tihu in the
Călimani Mts., Vârghis in the North Harghita
Mts.) became unstable during their growth and
collapsed, generating widespread large-volume
debris avalanche deposits. Edifice instability was
solved by volcano-basement interaction processes,
such as volcano spreading, at some large-volume
volcanoes (in particular those in the Gurghiu Mts.).
Volcano typology changed at the smaller-volume
constructs toward the southeastern terminus of the
range in the South Harghita Mts. from typical large
stratovolcanoes to smaller composite volcanoes,
dome clusters and isolated domes and simpler
internal structures. As a whole, CGH displays an
extremely particular evolutionary pattern strongly
suggesting a transient character and decreasing to
extinguishing volcanic activity along its length
from NW to SE.


Peculiarities of British parliamentary discourse are largely conditioned by context models of its participants, which influence the style and linguistic forms of their speeches. As context models are culturally predetermined, linguistic means used in parliamentary discourse have also certain linguocultural peculiarities. Centuries-old traditions of British parliamentary system find their reflection in the language and form an essential part of British parliamentary discourse. The adherence to these communicative norms, including different rituals, ceremonies and traditions peculiar to British political life and British political discourse, has a special symbolic meaning and is aimed at maintaining stability of the political system, respect for the state power and its authority.


Learning the human--mobility interaction (HMI) on interactive scenes (e.g., how a vehicle turns at an intersection in response to traffic lights and other oncoming vehicles) can enhance the safety, efficiency, and resilience of smart mobility systems (e.g., autonomous vehicles) and many other ubiquitous computing applications. Towards the ubiquitous and understandable HMI learning, this paper considers both "spoken language" (e.g., human textual annotations) and "unspoken language" (e.g., visual and sensor-based behavioral mobility information related to the HMI scenes) in terms of information modalities from the real-world HMI scenarios. We aim to extract the important but possibly implicit HMI concepts (as the named entities) from the textual annotations (provided by human annotators) through a novel human language and sensor data co-learning design. To this end, we propose CG-HMI, a novel Cross-modality Graph fusion approach for extracting important Human-Mobility Interaction concepts from co-learning of textual annotations as well as the visual and behavioral sensor data. In order to fuse both unspoken and spoken "languages", we have designed a unified representation called the human--mobility interaction graph (HMIG) for each modality related to the HMI scenes, i.e., textual annotations, visual video frames, and behavioral sensor time-series (e.g., from the on-board or smartphone inertial measurement units). The nodes of the HMIG in these modalities correspond to the textual words (tokenized for ease of processing) related to HMI concepts, the detected traffic participant/environment categories, and the vehicle maneuver behavior types determined from the behavioral sensor time-series. To extract the inter- and intra-modality semantic correspondences and interactions in the HMIG, we have designed a novel graph interaction fusion approach with differentiable pooling-based graph attention. The resulting graph embeddings are then processed to identify and retrieve the HMI concepts within the annotations, which can benefit the downstream human-computer interaction and ubiquitous computing applications. We have developed and implemented CG-HMI into a system prototype, and performed extensive studies upon three real-world HMI datasets (two on car driving and the third one on e-scooter riding). We have corroborated the excellent performance (on average 13.11% higher accuracy than the other baselines in terms of precision, recall, and F1 measure) and effectiveness of CG-HMI in recognizing and extracting the important HMI concepts through cross-modality learning. Our CG-HMI studies also provide real-world implications (e.g., road safety and driving behaviors) about the interactions between the drivers and other traffic participants.


The projection method with explicitly correlated Gaussians is used to demonstrate the existence of two doubly excited states of the positronium molecule (${\mathrm{Ps}}_{2}$). One is below the $\mathrm{Ps}(n=2)\phantom{\rule{4pt}{0ex}}+\phantom{\rule{4pt}{0ex}}\mathrm{Ps}(n=2)$ threshold, with ${A}_{1}$ symmetry, and the other is below the $\mathrm{Ps}(n=2)+\mathrm{Ps}(n=3)$ threshold, with $E$ symmetry. These states exist as resonances in the Ps-Ps continuum. Moreover, the resonance positions and resonance widths of the two states are calculated using the complex rotation method with basis sets obtained via the orthogonalizing pseudoprojector method. The resonance positions obtained using the complex rotation method agree with the results of the orthogonalizing pseudoprojector method. We also investigate the various structural properties of these states as well as the decay probabilities of $2\ensuremath{\gamma}$ emission due to electron-positron annihilation.


OVERVIEW OF POLITICAL AND ECONOMIC TRENDS IN THE MIDDLE EAST Our definition of the Middle East experiences some subtle variations year after year, although the Arabian Peninsula always constitutes the focal point. For example, this year we have left out Syria but have included Iran and Iraq. Egypt is covered within the Africa region, while Israel is discussed together with Europe for political reasons. What is certain is that we are talking about a large land mass roughly the size of Western Europe, with a total population of 170 million.


It is well-known that for Hilbert space linear operators 0 ≤ A and 0 ≤ C, inequality C ≤ A does not imply C ≤ A. We introduce a strong order relation 0 ≤ B ≪ A, which guarantees that C ≤ BAB for all 0 ≤ C ≤ B, and that C ≤ A when B commutes with A. Connections of this approach with the arithmetic-geometric mean inequality of Bhatia–Kittaneh as well as the Kantorovich constant of A are mentioned.


Abstract It is plausible that introduced species in the beginning of an invasion would be subjected to selection pressure to disperse rapidly so as to access unexploited habitats, but be subjected to selection pressure for more sedentary behavior once the available habitat was fully colonized. Using a mix of previously-published and new data from the introduced Brown Treesnake (Boiga irregularis) population on Guam we evaluated this scenario and found that: 1) Brown Treesnakes accessed a food bonanza when colonizing Guam, and then depleted it; 2) during the irruption, high-dispersing Brown Treesnakes most-likely benefitted by accessing undepleted or less-depleted food areas; and 3) after the irruption, high-dispersing Brown Treesnakes probably wasted effort through superfluous movement, and Brown Treesnake activity areas on Guam decreased in size in the 1990s, possibly in response to selection pressure for reducing superfluous movement. Nonetheless, 4) confined Brown Treesnakes had better fitness measures in 2004–2006 than snakes free to disperse, suggesting that selection pressure to reduce movements was ongoing. We conclude that selection in the post-irruption period promoted reduced dispersal and we observed appropriate change over generations, but we do not know the extent to which the observed changes reflect genotypic or phenotypic responses.


The structural evolution of nanocrystalline anatase TiO2 during high energy ball milling and after the ball milling during annealing was studied by means of ray diffractometer. It has been shown that mechanical activation induces the transformations from anatase to srilankite and rutile at room temperature and ambient pressure. During annealing, the crystallite size of the milled nanocrystalline TiO2 will increase with the rise of the annealing temperature. Srilankite, that is different from anatase, does not directly transform to rutile. Instead, srilankite firstly transforms to anatase and then anatase transforms to rutile. By comparison with the unmilled nanocrystalline Ti02, the temperature of the anatase - rutile phase transformation in the milled nanocrystalline TiO2 will be greatly decreased due to the additional energy caused by defects, lattice distortion and the refinement of the crystallite.


Aims To compare two different techniques for preparation of pre-cut lamellar corneal tissue for Descemet stripping automated keratoplasty. Background/Methods Eight donor lenticules were created with a full pass of the microkeratome blade, which resulted in a posterior lamella and a free cap (anterior lamella off group (AL-off)). Contralateral donor lenticules were created with an incomplete pass of the microkeratome blade, which resulted in a posterior lamella and a hinged anterior cap (anterior lamella on group (AL-on)). Endothelial cell density, cellular viability and corneal thickness were evaluated before dissection, and 4 and 24 h after dissection. Results Average pre-cut endothelial cell density was 2552.25 (±105) and 2572.25 (±110) cells/mm2 in the AL-off group and AL-on group, respectively (p=0.7). At 24 h cell density was 2404.87 (±74) in the AL-off group (p<0.01) and 2368.74 (±148) in the AL-on group (p=0.01). The mean percentage of trypan blue-stained cells was consistently higher in the hinged AL-on group. Corneal thickness increased by approximately 20% in both groups after 24 h cold storage. Conclusion Eye bank-prepared tissue offers the potential advantage of being screened for mechanical stress damage occurring during the automated dissection.


Flexible and printed electronics have been widely applied due to their low cost, scalability in manufacturing, and usability in biosensors as well as wearable electronics. However, there are some limitations on fabrication of these devices including thermal limitations. Thermal constraints are of significance since ion implantation at high temperatures is one of the most important stages of fabrication; therefore, despite these limitations, fabrication of flexible BJT is practically impossible through conventional methods. In this study, copper oxide was used for the collector and emitter area of Double Heterojunction Bipolar Transistor (DHBT) due to the low-temperature deposition of copper oxide through the printing method, and the ability to adjust the doping according to the deposition conditions. DC and high-frequency specifications of two transistors with PNP and NPN structures were simulated using two-dimensional semiconductor simulator atlas module of SILVACO software.

A novel hyperspectral imager design required a slit mask with bi-directional reflectance suppression between 600nm to 1650nm. A dark mirror coating was fabricated and patterned on a commercial off the shelf (COTS) edge filter.


Both Rome and astronomy each moved slowly toward the proofs and certainty sought by Galileo and by Bellarmine. Β. correctly fixes attention on the actions in 1616 by the Holy Office and Congregation of the Index, in which the geocentric position was affirmed by the consultore, then by the cardinals, and finally by the pope, Paul V. Of the trial of 1633 which condemned Galileo and forced his abjuration, B. writes much less, since this trial did not concern details of the Bible, nor indeed of celestial mechanics; rather it sought to determine whether or not Galileo had disobeyed the instructions given in 1616 from Pope Paul V to Galileo through Bellarmine about holding and advocating the Copernican position. Much of the blame for Galileo's woes after 1616 B. assigns to the Jesuit Order for its rigid conformity through "blind obedience" to the will and mind-set of the reigning pontiff. Long a Jesuit boast and glory, obedience, sealed by special vows, caused a dilemma for Jesuit scien tists who were also looking for scientific truth. And in B.'s documented account this led to the onset of intellectual "rigor mortis" after the scientific high points which had been reached in the period from Clavius to Scheiner. B. allows that there were "some isolated Jesuit scientists of the first rank including Boscovich and Sacchieri," but he passes over in silence their Jesuit brother scientists whose teaching and research in Europe and especially in the mission lands of China, Paraguay, the Pacific Isles, and India advanced the growth of knowl» edge among their people and also increased the sum of world treasures in mathematics, astronomy, and other humane sciences. Those inter ested in this point are alerted to consult Joseph F. McDonnell's small book, Jesuit Geometers (St. Louis: Institute of Jesuit Sources, 1990). Of special value in B.'s work are nine appendices which provide clear translations and expert documentation, especially on the supportive role of the Carmelite Father Antonio Foscarini on behalf of Galileo.


In order to improve the anti-seismic performance of skew bridge at high intensity seismic action, the paper establish the calculation and analysis model of skew bridge response based on finite element. The engineering example results show that the global stability of the structure decreases with the increase of skew angle in skew girder bridge, and the torque of bridge pier is increasing with the increase of skew angle.


An analysis of the catch associated with floating objects by the Mexican tuna purse‐seine fleet in the eastern Pacific Ocean during 1992–1993 was made to determine the spatial and seasonal distribution. The information used was generated by observers of the Programa Nacional de Aprovechamiento del Atun y Protección a los Delfines (PNAAPD). There was no clear seasonal and spatial distribution of floating objects examined in this study, however there were areas where floating objects were more common; the mouth of the Gulf of California, waters offshore Peru, and in oceanic waters. The largest catch of yellowfin tuna was offshore of Peru in winter. Two areas with largest (length) yellowfin tuna were the mouth of the Gulf of California and offshore Peru. For skipjack tuna, the largest catch was offshore Peru in winter, but the largest skipjack were caught between 120° and 130°W along 10°N in spring. The largest yellowfin tuna were captured by sets on bamboo, fish aggregating devices (FADs), planks and boards, and logs (trees or parts). The largest skipjack were captured by sets on dead whales, kelp paddies, planks and boards, and pallets and crates. Most of the sets were made during the early hours of the day but an important number of log sets were made in the early afternoon. For the period analyzed, floating objects were more frequent during fall and winter with the area offshore of Peru the most important.


Based on Poterba's asset-market model,taking the real price of houses and the size of the housing capital stock as analyzing tool,the effect of tax measures of adjusting asset market which have been carried since 2003 is studied.Through analysis,we consider that every tax policy is not the same.


The authors present an experimental study investigating the location of impurities in ice samples produced in the laboratory from aqueous solutions applying different freezing procedures. The ice samples containing either CsCl or 4,5,6,7-tetrachloro-2',4',5',7'tetraiodofluorescein (or Rose Bengal) were analyzed using μ-computed tomography, where the presence of air bubbles and the concentrations of the impurities were related to the absorption of the applied x-ray radiation. The ice samples were generated by placing liquid solutions in a freezer leading to a freezing from the exterior to the interior or by freezing from the bottom to the top or by immersion freezing with liquid nitrogen. The presented results indicate important differences concerning the distribution of the impurities in different compartments of the ice samples. The authors distinguish for the condensed phase two compartments: the solid ice matrix with low C1

In this chapter we study human computation algorithms that coordinate the efforts of a crowd to tackle complex tasks. A human computation algorithm is a set of instructions designed to be executed by humans and machines. Human computation algorithms can include function calls that are assigned to a crowd of individuals recruited to help contribute to the task. Depending on the task, one may recruit a crowd of paid workers through an online labor market such as Amazon Mechanical Turk, a crowd of friends or followers on social media services such as Facebook and Twitter, or a crowd of users of a web service who are willing or required to contribute to tasks. Unlike employees in traditional firms or dedicated volunteers on Wikipedia who tend to be available over time, keep track of context, and generally provide good solutions, the types of crowds we can readily recruit may consist of individuals who are only briefly involved in any particular task (e.g., up to 10 minutes), and include individuals who may or may not provide helpful inputs. Given these characteristics, 20


This paper reports observations on the toxicity of pentaquine 8 when administered in amounts higher than the recommended therapeutic dose (1). The purpose of the observations was to de-fine the margin of safety of the drug in clinical use. Pentaquine offers considerable promise as a radical cure of vivax malaria cent of the total hemoglobin, was converted to methe- moglobin. Both during and after treatment, blood oxygen studies demonstrated arterial and venous unsatura- tion (Table III). No weight loss occurred. Impotence persisted for two months only.


Routing in large-scale computer networks today is built on hop-by-hop routing: packet headers specify the destination address and routers use internal forwarding tables to map addresses to next-hop ports. In this paper we take a new look at the scalability of this paradigm. We define a new model that reduces forwarding tables to sequential strings, which then lend themselves readily to an information-theoretical analysis. Contrary to previous work, our analysis is not of worst-case nature, but gives verifiable and realizable memory requirement characterizations even when subjected to concrete topologies and routing policies. We formulate the optimal address space design problem as the task to set node addresses in order to minimize certain network-wide entropy-related measures. We derive tight space bounds for many well-known graph families and we propose a simple heuristic to find optimal address spaces for general graphs. Our evaluations suggest that in structured graphs, including most practically important network topologies, significant memory savings can be attained by forwarding table compression over our optimized address spaces. According to our knowledge, our work is the first to bridge the gap between computer network scalability and information-theory.


When carrying out medical imaging based on detection of isotopic radiation levels of internal organs such as lungs or heart, distortions and blur arise as a result of the organ motion during breathing and blood supply. Consequently, the image quality declines, despite the use of expensive high resolution devices. Hence, such devices are not exploited fully. There is a need to overcome the problem in alternative ways. Such as alternative is image restoration. We suggested and developed a method for calculating numerically the optical transfer function (OTF) for any type of image motion. The purpose of this reserach is restoration of original isotope images (of the lungs) by reconstruction methods that depend on the OTF of the real time relative motion between the object and the imaging system. This research uses different algorithms for the reconstruction of an image, according to the OTF of the lung motion, which is in several directions simultaneously. One way of handling the 3D movement is to decompose the image into several portions, to restore each portion according to its motion characteristics, and then to combine all the image portions back into a single image. As additional complication is that the image was recorded at different angles. The application of this reserach is in medical systems requiring high resolution imaging. The main advantage of this approach is its low cost versus conventional approaches.


In order to improve the protection ability of shared secret key of PKG trust gateway, a design method of privacy and confidentiality system of shared secret key of PKG trust gateway based on key technology is proposed. Combined with the analysis of frequency parameters of sinusoidal carrier, the encryption transmission and control of shared key of PKG trust gateway are carried out. By using sparse key characterization method, the data encryption key protocol of shared key of PKG trust gateway is constructed, the database interface of encrypted shared key of PKG trust gateway is constructed, the symbol distribution sequence of shared key detection of PKG trust gateway is obtained, and the arithmetic coding model of shared key of PKG trust gateway is established. Through key construction and arithmetic coding design, this paper analyzes the privacy and anti-attack ability of PKG trust gateway shared key in the process of random coding, and searches the ciphertext of PKG trust gateway shared key privacy under the environment of key tracking and information encryption, thus realizing the key information coding and privacy of PKG trust gateway shared key. Simulation results show that this method has better attack resistance, higher scrambling level of the output of shared key security detection, and better PKG trust gateway shared key encryption and shared key security detection capabilities.


High concentrations of certain 1-1 electrolytes in water induce a shift in the isoelectric point (IEP) of metal oxides to pH values substantially higher than the pristine IEP. With large cations, the nature of the anion does not affect the magnitude of these shifts, but with Li and Na the shift depends on the nature of the anion. This effect is termed the differentiating effect of small cations, and it has been studied in detail for anatase. The present results confirm the existence of the differentiating effect of Na for alumina. The anion sequence I > Br > Cl > ClO 4 > NO 3 observed for alumina is identical with that reported for anatase.

Introduction Magnum-psi is an experiment under design for the study of plasma-surface interactions in the regime of extreme heat and particle fluxes in high magnetic fields, allowing to address fusion reactor wall issues [1]. Currently, we investigate the plasma production and transport processes in a pilot version of the experiment: Pilot-psi. In this experiment the plasma produced in a cascaded arc is made to expand in a cylindrical chamber at low pressure. The neutral density is expected to be so low that a fluid description is not valid and information about neutral particles can only be achieved from a kinetic model. We have made use of the EIRENE code, which is based on Monte Carlo neutral particle transport, to model the interaction between the hydrogen plasma and recycling neutrals (H atoms, H2 molecules, and hydrocarbons) in the expansion vessel [2, 3]. Understanding and control of the erosion-ionization-redeposition cycle is crucial in extending the lifetime of divertor plates in future fusion devices.


Facial mask detection technology has become increasingly important even beyond the context of the COVID-19 pandemic. Along with the advancement in facial recognition technology, face mask detection has become a crucial feature for various applications. This paper introduces an Internet of Things (IoT) architecture based on a developed deep learning algorithm named You Only Look Once (YOLO) to keep society healthy, and secured, and collect data for future research. The proposed paradigm is built on the basis of economic consideration and is easy to implement. Yet, the used YOLOv4-tiny is one of the fastest object detection models to exist. A mask detection camera (MaskCam) that leverages the computing power of NVIDIA's Jetson Nano edge nanodevices was built side by side with a smart camera application to detect a mask on the face of an individual. MaskCam distinguishes between mask wearers, those who are not wearing masks, and those who are not wearing masks properly according to MQTT protocol. Furthermore, a self-developed web browsing application comes with the MaskCam system to collect and visualize statistics for qualitative and quantitative analysis. The practical results demonstrate the superiority and effectiveness of the proposed smart mask detection system. On the one hand, YOLOv4-full obtained the best results even at smaller resolutions, although the frame rate is too small for real-time use. On the other hand, it is twice as fast as the other detection models, regardless of the quality of detection. Consequently, inferences may be run more frequently over the entire video sequence, resulting in more accurate output.


Wavelets or wavelet analysis or the wavelet transform refers to the representation of a signal in terms of a finite length or fast decaying oscillating waveform known as the mother wavelet. This waveform is scaled and translated to match the input signal. The wavelet transform coefficients has been used as an index of similarity between a function f(t) and the corresponding wavelet, in the fields of pattern recognition and knowledge discovery. In these fields, the coefficients are generated to acquire a set of features. In this paper we explore the possibility of a reverse approach for generating wavelet coefficients by using a conventional similarity measure between the function f(t) and the wavelet. It is a reverse approach from the point that the wavelet coefficients are indices of similarity, and the proposed method is an alternate method to generate a normalized set of similarity indices, whose characteristics are similar to that of wavelet coeffcients. The idea could have lot of impact in future for multiresolution analysis and also can overcome the mathematical complexities induced by wavelet transform. We demonstarte WaveSim transform with an application in temporal data clustering.


Maternal deaths occurring in 1995 in San Luis Potosi were studied by means of verbal autopsies conducted during home visits with close family members of the deceased women. 2 controls matched by diagnosis were included for each case of hospital death. Maternal deaths were identified in a review of all death certificates for 1995. 52 maternal deaths were identified of which 2 from violent causes did not meet World Health Organization criteria and were eliminated. Verbal autopsies were conducted for 33 community and 12 hospital deaths and 22 controls. The maternal mortality rate based on the 50 deaths was 7.25/10000 live births 28% above the official rate based on 39 reported deaths. The maternal mortality rate varied widely in different municipios from 50.5 to 5.6 in the city of San Luis Potosi. The median age of the mothers was 30.4 years. The women were poor. Birth intervals were under 2 years in 53% of cases 33% of hospital cases and 42% of controls. 9% of deaths occurred in the first half of pregnancy 15% in the second half 18% during delivery 31% on the 1st postpartum day and 27% on the 2nd through 42nd day. 17% of the women did not desire the pregnancy and 33% had no prenatal care. 19% of the victims were abused during the pregnancy. The delivery was cesarean in 45% of cases 60% of hospital cases and 90% of controls. 56% of cases were attended by physicians. The medical cause of death was hemorrhage in 48% toxemia in 26% and indirect causes in 18%. 60% of deaths occurred in hospital 28% at home and 12% en route to the hospital.

Nepal embarked on a full-fledged federal system with the adoption of a new Constitution in 2015. Progress has been made in terms of setting up of key institutional structures, and strengthening the regulatory environment for federalism, and to some extent staff deployment. But significant gaps still exist between the needs and existing capacity at all levels of government. A Federalism Capacity Needs Assessment (FCNA) was conducted in 2018-19 for the Government of Nepal (GoN). The FCNA used a broad definition of capacity, including organizational (physical and human) and institutional (laws and regulations) elements. This paper presents progress in the implementation of federalism based on the findings of the FCNA.


ABSTRACT: Brewer's spent grain (BSG) is a residue from brewery production, that can be reused as adsorbent of heavy metals like Chromium (Cr). In this study, BSG was used as a biochar for Cr adsorption in batch adsorption experiments. The biochar pyrolysis temperature (500, 600 and 700ºC), pyrolysis time (30, 105 and 180 minutes) and zinc chloride concentration (5, 12.5 and 20%) were evaluated and optimized from a fractional factorial design. An equilibrium adsorption capacity of 78.13 mg.g-1 and a yield of 26.42% were achieved using 700ºC, 30 min, 12.5%. This biochar was applied to the adsorption of Cr in aqueous solution, under different stirring speeds (100, 150 and 200 rpm). The higher agitation speed reduced the adsorption capacity of the coal from 90 to 72 mg.L-1. In addition, the Cr adsorption equilibrium was reached before 100 min. The pseudo-first order model best described the Cr adsorption kinetics. The Redlich-Peterson isothermal model best fitted the experimental data, with the parameter g (close to 1) suggesting Langmuir's assumptions as the most appropriate to describe the adsorption of Cr on the optimized activated carbon.


In this work, we report for the first time, the synthesis of several carbon nanotube (CNT)/polyaniline (PANI) nanocomposites obtained through interfacial polymerization, in which the resulting material is obtained directly as a transparent and freestanding film at the water−toluene interface. The films are obtained spontaneously with high stability and can be easily transferred with high optical quality to any kind of substrate or directly to a desirable device. Samples containing several CNT/PANI ratios have been prepared. The characterization of the resulting materials was carried out by FT-IR, UV−vis-NIR, and Raman spectroscopy, X-ray diffraction, cyclic voltammetry, scanning and transmission electron microscopy, and conductivity measurements. The results indicate that the polymerization of aniline starts at the carbon nanotube walls, resulting in polymer-coated CNTs. A π−π interaction between the CNTs and the PANI is proposed. The formation of the self-standing films is discussed in terms of the stabi...


This paper presents an ultrasonic micro power generator using the piezoelectric direct effect phenomena. The micro power generator consists of 2 main elements, a movement matt including PZT elements and an energy harvesting circuit. The movement matt is made up of a four PZT elements each element creating a cantilever beam. The energy harvesting circuit is made up of an LTC3588 Evaluation Board and an LDR night light. Computer simulation and modelling using finite element analysis for the proposed generation method is discussed and used in the design and development process. Finite element analysis has been used to evaluate the PZT structure by performing an algebraic solution of a set of equations, describing an ideal model structure, with a finite number of variables. The simulation and modelling enabled to select the material and best method of operation. A prototype of the proposed generator was built and tested. This demonstrated that piezoelectric material could produce up to 36V, although the overall impedance of such devices was shown to be linear depending on the force applied with an average of 36MΩ. The Energy harvesting circuit allowed an output super capacitor to be step charged taking an average time of 35-minutes to charge and 2-minutes to discharge through the selected load.

Significant changes have been made to the design of the sector magnet of the RIKEN SRC (superconducting ring cyclotron). The changes are: (1) the cyclotron is almost completely covered with soft-iron slabs of 0.8 m in thickness, except in the central region, to reduce stray fields, and (2) the cold-pole scheme has been replaced with a warm-pole scheme. Owing to this magnetic shield, the stray fields, magneto-motive forces, electromagnetic forces, and so on are significantly reduced. New design of the real sector magnet is described in this report.


The e.s.r. spectra of cyclohexylmethyl radicals have shown that two conformations, one with the CH2˙ group equatorial and one with the CH2˙ group axial, can be distinguished. The Hβ h.f.s. of the axial conformer is large because rotation about the Cβ—Cα˙ bond is hindered by axial hydrogens at C(3) and C(5) in the ring. This proved to be a very useful property enabling the conformations and ring-inversion barriers of cyclohexanes, cyclohexenes and related radicals to be studied by e.s.r. spectroscopy. In addition the various conformers of larger rings (up to 15-membered) also show different spectra. Their preferred conformations and the dynamics of 'corner migration' in the medium rings have been investigated. The e.s.r. spectra of cycloheptenylmethyl radicals showed the presence of a minor conformer which suggested that transannular cyclisation might be important. Product analysis confirmed that bicyclo[3.2.1]octane can be obtained in good yield.The stabilisation energy of cyclopropylmethyl radicals was determined from exchange-broadened spectra; several cyclic homoallyl-type radicals were shown to have essentially zero stabilisation.Hydrogen abstraction from small strained bicycloalkanes, including bicyclo[n. 1. 0]alkanes, spiro[2.n]alkanes and spiro[3.n]alkanes yields the corresponding strained bicycloalkyl radicals, and their rearrangements have been followed by e.s.r. spectroscopy. Bicyclo[1. 1. 1]pentane and bicyclo[2. 1. 1]hexane are unusual in that bridgehead radicals are formed. Bicyclo[2. 2. 0]hexane also shows significant bridgehead reactivity and provides the first example of an SH2 reaction involving a four-membered ring. Bicyclo[3. 2. 0]heptane, in which four- and five-membered rings are fused together, does not undergo this SH2 reaction with halogens. The rates of rearrangement of several cycloalkyl and bicycloalkyl radicals have been determined by kinetic e.s.r. spectroscopy.


Freezing injury to overwintering flower buds of apricot (Prunus armeniaca L.), European plum (P. domestica L.), Japanese plum (P. salicina Lindl.), peach (P. persica (L.) Batsch.), sweet cherry (P. avium L.) and sour cherry (P. cerasus L.) was found to be associated with an exothermic process detected on the time temperature profile. This exothermic process varied with seasonal fluctuations in the hardiness of 2 peach cultivars and was consistent with the hardiness of 5 cultivars tested on 3 dates during winter. No similar exotherm was detected in pear and apple. These results suggest that flower bud injury in some Prunus species was related to a specific event that involved freezing of a 'bound' or 'supercooled' fraction of water. This fraction of water remained unfrozen in the flower bud until the temperature fell below a critical level which in our studies was as low as -27°C. Exotherm flower bud hardiness in these fruit species.


Interdomain routing in the Internet is coordinated by the Border Gateway Protocol (BGP). BGP allows each autonomous system (AS) to apply diverse local policies for selecting routes and propagating reachability information to others. This exibility is crucial in the decentralized and commercial environment of today's Internet. However, BGP permits ASes to have connicting policies that can lead to route divergence, which can cause an AS to oscillate between two or more routes to a particular destination. In this paper, we propose a set of guidelines for an AS to follow in setting its routing policies, without requiring coordination with other ASes. Our approach exploits the Internet's hierarchical structure and the commercial relationships between ASes to impose a partial order on the set of routes to each destination. The guidelines conform to conventional traac-engineering practices of ISPs, and provide each AS with signii-cant exibility in selecting its local policies. Furthermore, the guidelines ensure route convergence even under changes in the topology and routing policies. We present a formal model of BGP that includes ASes with multiple BGP speakers, both interior BGP (iBGP) and exterior BGP (eBGP), and additional BGP attributes. Drawing on this model, we prove that following our proposed policy guidelines guarantees route convergence. We also describe how our methodology can be applied to new types of relationships between ASes, how to verify the hierarchical AS relationships, and how to realize our policy guidelines. Our approach has signiicant practical value since it preserves the ability of each AS to apply complex local policies without divulging its BGP conngurations to others.


Between 1960 to 1980, America's mainstream society considered magic as a combination of supernatural nonsense, themes of entertainment, and an umbrella word to describe indescribable events. However, Wicca, the counter-cultural Pagan religion, adopted the word as a form of resistance against a predominantly male-driven culture. By transforming and inventing socially devalued words such as magic into magick, Wiccans attempted to salvage and validate their practices. This allowed Wiccans to create their culture within the society that rejected them, and provide new interpretations of magick to separate from mainstream definitions. For instance, the practice of spells such as abracadabra exemplified how new categorical inventions and interactive kinds could be used to reconstruct the idea of magic. Additionally, Constance Wise's application of the metaphysical philosophy of process thought demonstrated the reconstruction and invention of magick into a paradoxically new concept founded on old traditions. Feminist Wiccan subgroups adopted these new values and established new symbols from pre-existing traditions in order to further sociopolitical goals, particularly in respect to gender equality. From these instances, magick served as a tool and mediator for Feminist Wiccans against their social environment.

In a previous work, we examined subgap states in highly doped amorphous In-Ga-Zn-O (a-IGZO) films by hard x-ray photoelectron spectroscopy (HX-PES) and found they had subgap electronic states above the valence band maximum (VBM) with the densities > 5 × 1020 cm−3 and just below the Fermi level with the densities > 5 × 1019 cm−3 [K. Nomura, T. Kamiya, H. Yanagi, E. Ikenaga, K. Yang, K. Kobayashi, M. Hirano, and H. Hosono, Appl. Phys. Lett. 92, 202117 (2008)]; however, their electron densities (Ne > 3 × 1019 cm−3) are rather high and not compatible with rational properties required for active channel layers in thin-film transistors (TFTs). In this work, we report the effects of Ne and thermal annealing on the subgap states in order to provide the data useful for actual TFTs. It was found that the low-Ne a-IGZO films had extra subgap states above VBM similar to the previous report, but their densities were as small as ∼2.0 × 1020 cm−3 for the highly resistive, wet-annealed a-IGZO films.

The purpose of this study is how compassion has been affected in India and European countries, in our country even in the absence of health facilities, Covid-19 has less effect than other countries, especially in Europe. It is being observed through statistical analysis and statistical process etc. that the effect of COVID-19 in India is less and in European countries the effect of COVID-19 may be more due to many factors like environmental factors, differences in defense response system etc. One possible reason behind the decrease in the number of infected can be believed that there has been herd immunity. Vinita Bal of India's National Institute of Immunology believes that herd immunity can be behind this. Herd immunity means the level where immunity has developed among so many people of a community that there is no more infection. This was either due to a large number of people getting sick or due to vaccination. Thus we can say that in comparison to European countries, infection rate, mortality and recovery rate in India has been very good.


An enhanced scalable compact model for on-chip RF spiral inductors is presented in this paper. By considering the layout and technology parameters under quasi-static approximation, the model elements are all expressed analytically and based on physics assumption. The proposed approach improves the accuracy of the previous physical based scalable model, and considers the frequency dependant behavior of spiral inductors such as the substrate coupling, the skin and proximity effect.


A stereological analysis of cells from the mesophyll, vascular bundles and central parenchyma in leaves of the halophyte Suaeda maritima (L.) Dum is described. The volume fraction of vacuole was greater in plants grown under saline conditions when compared with those under non-saline conditions, and there was a concurrent increase in the surface density of the tonoplast. The volume fraction of chloroplasts and cell wall fell under saline conditions, while that of the intercellular spaces increased. Salinization of the growth medium was accompanied by a large increase in the fraction of the cell volume occupied by the mitochondria: the increase in surface density of mitochondrial membranes was some 72% when averaged over all the cell types analysed.


Fusarium culmorum is a fungal pathogen causing head blight and foot/root rot on many small-grain cereal as well as ear rot and stalk rot on maize. In addition to yield losses, F. culmorum also produces mycotoxins such as the trichothecenes deoxynivalenol and nivalenol. Triazoles are widely used around the world to control Fusarium spp. but results are not always satisfactory and resistances within the Fusarium genus have been reported. In order to evaluate the triazoles sensitivity of F. culmorum, a collection of 105 strains with different origins, years of isolation, host plants and chemotypes was constituted. The concentrations leading to a 50 % reduction of the optical density (EC50) of those strains towards tebuconazole and epoxiconazole were evaluated using microtiter plate assays. Significant differences of EC50 towards tebuconazole (range = 0.15 to 1.38 mg/l) and epoxiconazole (range = 0.26 to 1.86 mg/l) were observed. Cross-resistance was found between fungicides (ρ=0.6), with tebuconazole being more efficient (mean=0.32 mg/l) than epoxiconazole (mean=0.57 mg/l), although an interaction between the factors 'strains' and 'fungicide' was noticed. When compared to F. graminearum and F. cerealis, F. culmorum appeared to be the most sensitive species. Interestingly, nivalenol-producing strains of F. culmorum were more resistant to both fungicides compared the deoxynivalenol-producing ones. prix Marasas pour le meilleur poster


ABSRACT The denial of workers' active involvement in decision-making and the attendant negative attitude to work necessitate the need for this study to examine the impact of participative management (PM) on employee job performance in a Nigerian Manufacturing Industry. Other specific objectives were to: examine the impact of participative management on employee job performance; and, evaluation of the relationship between indirect participation dimensions and employee job satisfaction. Questionnaire was served to 240 out of 600 employees of the manufacturing organisation through stratified, simple random sampling techniques. Two hypotheses formulated were tested through regression and correlation analysis. The findings revealed that (PM) had a significant influence on employee job performance (r 2 =76.5%, p-value<0.05) and that indirect participation dimensions and employee job satisfaction correlated (P-value<0.05). The study concluded that PM remains an important management strategy for improving employee performance with recommendation that organisation should emphasize comprehensive task and contextual performance behaviour strategy through the adoption of participative management.


We have designed a novel query retrieval scheme for the information just in time (iJIT) system to retrieve handwritten annotations from digital documents based on typed/handwritten query. The two key components of the developed query retrieval system (QRS) are the character recognition engine and the query retrieval engine. The character recognition engine uses Tesseract 2.01 open source Optical Character Recognition (OCR) Engine under Apache License 2.0 and is trained with handwritten samples from different users. The character recognition engine receives real-time digital pen generated data, and produces segmented-recognition result. The query retrieval engine, resolves the index / query requests from the users for possible information update / retrieval. In case of a handwritten query, the query retrieval engine interacts with the recognition engine to create / update the inverted index table with recognized word labels with annotation indices. In the case of typed text query, the inverted index table is searched directly to retrieve the best matches of annotation indices using a q-gram based approximate string matching technique. A HMM - Viterbi algorithm is finally implemented to find the optimum recognized character sequence in each word using a fuzzy character confusion matrix.


Introduction: Modular prostheses were first developed for use in total hip arthroplasty (THA) in the 1980s as a potential solution to the problem of leg length inequality. There is much literature discussing the advantages and disadvantages of modularity in THA but there are few studies directly comparing modular and non-modular prostheses and their accuracy in restoring normal anatomy. Our aim was to assess whether modularity in THA improves the restoration of femoral offset and leg length. Methods: An analysis of post-operative radiographs of 76 patients who underwent THA - 38 using modular and 38 using non-modular prostheses was undertaken. The femoral offset and leg length of the operated and un-operated hip were measured for each patient. Inter-and intra-observer errors were reduced to a minimum. A two-tailed T test was then applied to the data. Results: Restoration of leg length (to within +/− 10mm of the un-operated hip) was achieved in 81.6% of patients in the non-modular group, compared to 78.9% in the modular group (p=0.60). On average, the modular system increases leg length of the operated hip by 0.64mm compared to the non-modular system, which reduces leg length by 3.76mm (p=0.016). The femoral offset is restored to within 5mm of the un-operated hip in 60.5% of modular THA and in 55.3% using a non-modular prosthesis (P=0.48). On average, modular prostheses increased offset by 0.85mm and non-modular prostheses by 0.15mm (P=0.64). Discussion: The modular and non-modular hip prostheses are equally successful in achieving restoration of leg length and femoral offset to the pre-pathological state.


The purpose of this study was to examine the perceptions of the Outcome Questionnaire (OQ) following its implementation in a university-based psychological services training centre. Participants were doctoral-level student clinicians (N=49), clinical supervisors (N=17), and clients (N=24). Data was collected through surveys, semi-structured interviews, and focus groups. Findings indicated the majority of clinicians used the OQ to monitor outcomes and the majority of stakeholders perceived it as useful. However, the extent to which the information provided by the OQ was being used was variable. Lessons learned for implementation of performance measurement systems within mental health services are discussed.


Undergraduate Party members are the most vivid group in the Party,representing the future and hope of Chinese Communist Party.Aiming at the current problems existing in organization and discipline cultivation for the undergraduate Party members,this paper puts forward that the undergraduate party members should strengthen their organization and discipline cultivation from four aspects: correctly understanding the relationship between the party members and the party,carrying out the Party's democratic centralism,correctly handling the relationships among party members,unifying the voluntary and complying.


Introduction Between September 1978 and July 1980 I managed a large proportion of the cases of acute appendicitis in the Hastings Health District and it was my habit to observe the facial expressions of patients while palpating the abdomen. I have noticed that many patients with acute appendicitis have a characteristic expression which can be elicited by gentle pressure over the appendix. I have not found this described in the literature; a computer search back to 1966 failed to reveal a sing e article about facies in acute abdominal disease.


The authors study the spectral characteristics of multidimensional stationary sequences, namely, estimators of the cospectrum, the quadrature spectrum, the amplitude and phase spectra, and also the square of the modulus of the coherence spectrum. For these they carry out investigations of both classical periodogram estimators, as well as time shift estimators. Bibliography: 13 titles.


Post-partum hemorrhage (PPH) is a common cause of maternal mortality in developing countries. Active management of postpartum hemorrhage by an uterotonic drug decreases the rate of postpartum hemorrhage. Studies suggest that the use of misoprostol may be beneficial in clinical settings where oxytocin is unavailable. The aim was to compare the safety and efficacy of oxytocin and misoprostol when used in the prevention of PPH. It is a double-blind study with 200 pregnant women who had a vaginal delivery were assigned 100 allocated in each groups of patients receiving either 800μg of misoprostol, rectally, or 5 IU of intravenous oxytocin, after delivery of the baby. Intra-operative bleeding, hemoglobin level before and 24 hour after operation, blood pressure before and after the administration of the drugs, and adverse drug effects were noted. The quantity of blood loss was high in the oxytocin group in comparison to the misoprostol group. There was no significant difference in the decrease in hematocrit and hemoglobin between the two groups. Although there was no significant difference in the need for transfusions and uterotonics between the two groups. Fever and chills are significantly higher among misoprostol patients. Study indicates that misoprostol may be considered as an alternative for oxytocin in low resource clinical settings.

The reissue of Goodwin's Moods and Tenses, once the trusted companion of every serious student of Greek, which has been out of print for many years, is a notable event; and the student's pleasure at the recovery of a valuable tool of his trade will be greatly increased by the modesty of the price, which puts it within the reach of everyone. That a book which was published at 14s. in 1889 should be reissued in 1965 at 205.—and not in a paperback but in as solid a format as the original (with the improvement of a brighter green)—seems almost too good to be true. The publishers deserve the gratitude of all students of Greek, and their reward should be assured. The English version of Theodor Gomperz's Griechische Denker was first published between 1901 and 1912; it has now been reissued in four substantial paperbacked volumes at 1 y. each. Some of the author's views and interpretations are now out of date or at least out of fashion, but the work as a whole remains a classic, and may still be consulted with great profit. Entries are invited for the third award of the Dougal Malcolm Prize for Composition in Horatian Verse, administered by the Horatian Society. Candidates, who must be pupils at a school in the United Kingdom, should submit a Latin poem, either original or translated, of not more than forty lines on any subject in any metre used by Horace, by 30 April 1966, to F. R. Dale Esq., C.B.E., D.S.O., M.C., 48 Ridgeway, N.W. 11. The value of the prize will be three guineas. The second award of the prize has been made to S. Ireland, of Eston Grammar School, Middlesbrough: proxime accessit, A. W. Dickinson, Liverpool Collegiate School. Pauly-Wissowa continues to fill its gaps, large and small. Among the major articles in the 588 Pages of the latest Supplementband (x) are those on Athens (a curious omission) and Potidaea, Thales, Vegetius, Trajan, the Vandals, the Wonders of the World, populates, cohortes urbanae, Military Law, and a series of legal terms (creditum, legitimatio, origo, patrimonium). New articles on Side and disciplina militaris replace those previously published, and there are long supplementary articles on Heraclitus and Pythagoras, Aratus of Soli, and Ptolemy the Geographer. From the Oxford Press come two welcome paperback editions of wellknown books on Greek Tragedy. One is Gilbert Murray's Euripides and his Age (1918), for which Professor H. D. F. Kitto has written an introduction; the other Sir Maurice Bowra's Sophoclean Tragedy (1944).


Abstract Objectives: We sought to determine the efficacy of psychotropic drug in the management of BMS-like oral symptoms in patients with reticular oral lichen planus (R-OLP) refractory to conventional therapies, and its impact on anxious and depressive symptoms. Materials and methods: We enrolled 28 cases of symptomatic R-OLP. The Numeric Rating Scale (NRS), the Total Pain Rating Index (T-PRI), the Hamilton rating scales for Depression (HAM-D) and Anxiety (HAM-A) were performed at baseline (time 0), after 2 months of topical clonazepam (time 1) and after 6 months of benzodiazepine and antidepressant drugs (time 2). Results: R-OLP patients showed a statistically significant improvement in the NRS and T-PRI scores from time 0 [median: 9.0 (IQR: 7.2–10.0) and 10.5 (IQR: 7.0–13.0), respectively] to time 2 [(median: 2.0 (IQR: 2.0-3.0) (p < .001) and 3.0 (IQR: 2.0–4.7) (p < .001), respectively]. Similarly, the HAM-A and HAM-D scores showed an improvement from time 0 [(median: 15.0 (IQR: 10.2–17.8) and 13.0 (IQR: 12.0–15.0), respectively] to time 2 [median: 6.0 (IQR: 4.0–7.0) (p < .001) and 5.5 (IQR: 4.25–6.0) (p < .001), respectively]. Conclusions: Psychotropic drugs turned out to be effective in the management of BMS-like oral symptoms in R-OLP patients refractory to conventional immunosuppressive therapy, although in a long-term period.


A two-input, two-output element switch for use in future ATM (asynchronous transfer mode) switching systems for buffered banyan networks with CASO (contents associated output) buffers has been realized in 0.8-μm BiCMOS technology. Three key features of the element switch architecture are CASO buffers to increase the throughput, SCDB (synchronization in clocked dual-port buffer) to make asynchronous cell transmission possible on the element switches with a simple structure, and CELL-BYPASS, which lowers the latency (the time of cell passage through the element switch). The element switch adopted an ECL (emitter coupled logic) interface to achieve high through rate. Using these techniques, a high-speed, low-latency, very-large-scale buffered self-routing switching network is easily constructed


The Global Positioning System (GPS) is highly reliable and accurate when used outdoors.However, in indoor environments, due to the additional signal loss incurred by the walls of the buildings, the detection and decoding of GPS signals becomes a difficult task. As a solution to the indoor area coverage problem, an indoor positioning system based on GPS repeaters and a modified positioning algorithm is proposed, designed, and tested. A prototype indoor positioning system for 1D/2D positioning is built using directional GPS antennas and low‐noise amplifiers (LNA). The modified positioning algorithm is used for the real time processing of captured live GPS data. All the system components are integrated and positioning is obtained for the evaluation of the system performance. Results of the experiments show that the proposed system can be used for indoor positioning in locations where there is no GPS signal reception. The proposed system facilitates the continuation of GPS services indoors with hardware additions to the buildings and only a software update to a standard GPS receiver. © 2013 Wiley Periodicals, Inc.

A 3D numerical model was developed for studying the multiphase flow and heat transfer process in a radiant syngas cooler (RSC). Realizable k-ϵ turbulent and discrete random walk models were adopted to simulate gas phase and particle phase flow fields, respectively. The surface temperature of the membrane wall was calculated by heat flux balance equations. The calculated temperature distribution was validated by comparing calculated values with measured data of an industrial RSC. Four different membrane wall arrangements of RSC, namely, ordinary membrane wall (OMW), partial division wall (PDW), annular division wall (ADW), and fin division wall (FDW), were designed for a specific condition.


Plasma-based physical vapor deposition (PVD) process developments occurring over the past few decades now allow the production of tribological coatings with properties which were previously unachievable. These new coatings will be critical in the creation of new products with improved functionality and performance, which will have a dramatic impact on, for example, their operating efficiency and lifetime. The key pioneers behind these PVD developments are discussed here, together with some significant process innovations. The latter include ionization-enhancing systems, such as thermionic assistance and arc evaporation, as well as unbalanced magnetron sputtering and magnetic plasma confinement. These developments have provided the impetus behind the recent growth in the technology field which we now know as surface engineering, and the recognition that surfaces provide the functionality and durability for almost all engineered products. Vacuum plasma technologies can thus be regarded as critical, not only for functional devices and thin film applications (for which their importance was previously most recognized), but also for structural product applications; they will thus underpin the entire spectrum of manufacturing industry.


An interesting component of Opuntia ficus-indica is the mucilage for its properties and industrial uses. However, the great variability of its quantity and quality caused by different growing conditions, the hydroponic system is an alternative. The objective of the present study was cultivating 4 species of Mexican Nopal in a hydroponic system, extract and characterize the mucilage. The characterization consists of pH, ºBrix, colour, proximal analysis, phenols, antioxidant activity, crystallinity, and chemical bonding constituents. 'Copena F1' is the best alternative for production of biomass and mucilage. 'Villanueva' had high levels of phenols (1,311.83 mg GAE g-1), antioxidant capacity ABTS·+ (6,301.12 mg TE g-1) and FRAP (536.26 mg GAE g-1). A large amount of lipids (1.39%), and nitrogen-free extract (49.27%). The functional groups of the mucilage were identified (-OH, -CH, -CH2, -CH3, C=C, HCH, -CHO) and gypsum, cellulose, SiO2 CaSO4, C2H2K2O5, CaCO3 and CaH2 by X-ray diffraction. The hydroponic system is a viable alternative for production of nopal and mucilage of high-quality mucilage that can be used in several sectors of the industry.


The purpose of this research was to determine the influence of industrial activities in the EMAARS-EP, and the quality of occupational safety and health.

The last decade has seen an explosive growth in the range of electronic instruments available from manufacturers 'off the peg'. We now see not only signal generators, impedance bridges, oscilloscopes and the like, gradually increasing their performance in respect of precision and range of frequency or speed, but also some very elaborate systems.


The leading factors triggering neoangiogenesis include matrix metalloproteinases. Objective: to assess the prognostic significance of the level of MMP-2 expression in colon cancer. Material and methods. The clinical and morphological analysis of 72 cases of colorectal cancer resected over 2001-2011. Immunohistochemical studies using mouse monoclonal antibodies to MMP-2 were performed in the laboratory of Collegium Medicum Bydgoszcz. Results. The research showed a relation between the level of matrix metalloproteinase-2 expression in colon cancer to the age of the patients, level of differentiation, invasion and metastasis of cancer, and survival of patients. However, the data suggest there is no direct relation between an increase in the marker expression and tumor progression.


The purpose of this case study was to evaluate the Project-Based Learning that was
implemented at the Mechanical Engineering Department in a polytechnic in Malaysia.
Project-Based Learning is a different approach than the traditional learning in the
sense that it is a student-centered learning approach based on the principles of
constructivism. This study employed CIPP model because it is a comprehensive model
for evaluation. However, the context dimension was dropped because the present
study did not focus on the needs analysis. The input dimension assesses the module
and supervisor"s readiness. The process dimension evaluates the project activities and
the product dimension assesses the quality of the product. This study involved a
random sample of 118 students and 43 supervisors in the Mechanical Engineering
Department. The study found that both the students and supervisors agreed that
Project-Based Learning approach is appropriate for the final project course J5012. In
addition, both groups of respondents believed that the supervisors possesed adequate
technical knowledge and implemented supervisory duties effectively. Nevertheless,
students perceived the module content was hard to understand. In terms of finding
ideas, both students and supervisors agreed that students were encouraged to assess
the real problem by their supervisors. However, the supervisors were uncertain
whether the students went to the library to get the ideas for their project. In addition,
the supervisors were barely agreed about the creativity of the students in finding the
project ideas. However, students and their supervisors believed that critical thinking
and creativity were needed in the Project-Based Learning. The respondents also
believed that e-SOLMS helped the students to work in group to complete the project.
In terms of project duration, the students were uncertain regarding the sufficiency of
the time to complete the project. The students barely agreed that the machines and
equipments at the polytechnic were appropriate for the project. In terms of product,
both students and supervisors believed that the students" products were marketable
because they have good design and aesthetic values. Finally, the present study puts
forward a new framework for Project-Based Learning.


"Racism is a moral issue and of concern for moral educators, with recent social movements such as #BlackLivesMatter highlighting how far we are from obliterating racial oppression and the unearned privilege whiteness confers" (Lynch et al., 2017, p. 129). Vaines suggests that Home Economics is a profession grounded in morality, and one that is in a process of transformation (1997). Should this transformational process not, therefore, hold ongoing issues such as racism as a priority when developing clearer definitions of its mission and the pedagogical models that will enable this mission to be fulfilled? Much thought has gone into deconstructing the multicultural educational model and replacing it with the deliberately critical, anti-racist pedagogical approach, though there remains much room for development of this pedagogy in pre-tertiary education. Our paper provides an introduction to the theoretical principles of anti-racist pedagogy, what it means for students and teachers, as well as specific strategies and lessons that can be used within the Home Economics classroom.

Mersereau, D. and DiTommaso, A. 2003. The biology of Canadian weeds. 121. Galium mollugo L. Can. J. Plant Sci. 83: 453–466. Galium mollugo L. (smooth bedstraw) is a long-lived perennial broadleaved plant that reproduces both vegetatively and by seed. Galium mollugo can be a strong competitor in long-lived forage crops such as bird's-foot trefoil (Lotus corniculatus L.), timothy (Phleum pratense L.), and orchard grass (Dactylis glomerata L.), as well as in short-lived forage crops such as red clover (Trifolium pratense L.) and yellow sweet-clover [Melilotus officinalis (L.) Lam.]. It is also a problem weed in spruce plantations and re-vegetation areas. Livestock typically avoid this species, allowing it to become well-established in pastures where it outcompetes more favourable species. Moreover, G. mollugo is viewed as a successful invasive species because of its ability to colonize and proliferate in areas such as established meadows where most invasive species do not thrive. In natural meadow communities, G. mollugo is often a dominant species that is capable of colonizing areas left vacant by the death and/or displacement of other species. Under favourable conditions, G. mollugo growth and clonal expansion can increase rapidly. Galium mollugo is generally tolerant to herbicides such as 2,4-D, MCPA, 2,4-DB, and dicamba.


The directional variation of the velocity gradient in a supersonic, radiatively accelerated flow gives an effectively anisotropic character to the line-scattering process. This leads to surprising consequences in source geometries that are more complex than isolated nonrotating stars. In this paper we explore the wind dynamics from a planar slab atmosphere that is irradiated by an external oblique source, within the framework of standard Castor, Abbott, & Klein (CAK) wind theory. We show that the presence of externally incident radiation can be surprisingly effective at tilting the flow away from the vertical. Even more surprising is our conclusion that such illumination should often enhance the mass loss and can even induce outflow from a surface with no intrinsic radiation source. We examine the physical causes of such "line-driven ablation" and discuss the potential implications for modeling line-driven flows in massive-star binary and accretion-disk systems.


This paper describes a broadband differential regulated cascode (RGC) transimpedance amplifier (TIA) designed in 130-nm SiGe process. Cross-coupled structure and two common emitter (CE) stages feedback loop are employed to reduce input impedance. The simulation results show that the proposed TIA has 46.35-dB $\Omega$ differential transimpedance gain and 35.6-GHz bandwidth (BW). Overall, it achieves a clear 100-Gb/s PAM4 eye diagram. The total power consumption is 84mW.


Portable devices play an essential role where edge computing is necessary and mobility is required (e.g., robots in agriculture within remote-sensing applications). With the increasing applications of deep neural networks (DNNs) and accelerators for edge devices, several methods and applications have been proposed for simultaneous crop and weed detection. Although preliminary studies have investigated the performance of inference time for semantic segmentation of crops and weeds in edge devices, performance degradation has not been evaluated in detail when the required optimization is applied to the model for operation in such edge devices. This paper investigates the relationship between model tuning hyperparameters to improve inference time and its effect on segmentation performance. The study was conducted using semantic segmentation model DeeplabV3 with a MobileNet backbone. Different datasets (Cityscapes, PASCAL and ADE20K) were analyzed for a transfer learning strategy. The results show that, when using a model hyperparameter depth multiplier (DM) of 0.5 and the TensorRT framework, segmentation performance mean intersection over union (mIOU) decreased by 14.7% compared to that of a DM of 1.0 and no TensorRT. However, inference time accelerated dramatically by a factor of 14.8. At an image resolution of 1296×966, segmentation performance of 64% mIOU and inference of 5.9 frames per second (FPS) was achieved in Jetson Nano's device. With an input image resolution of 513×513, and hyperparameters output stride OS = 32 and DM = 0.5, an inference time of 0.04 s was achieved resulting in 25 FPS. The results presented in this paper provide a deeper insight into how the performance of the semantic segmentation model of crops and weeds degrades when optimization is applied to adapt the model to run on edge devices. Lastly, an application is described for the semantic segmentation of weeds embedded in the edge device (Jetson Nano) and integrated with the robotic orchard. The results show good spraying accuracy and feasibility of the method.


The magnetic transparency of biological tissue allows the magnetic nanoparticle (MNP) to be a promising functional sensor and contrast agent. The complex susceptibility of MNPs, strongly influenced by particle concentration, excitation magnetic field and their surrounding microenvironment, provides significant implications for biomedical applications. Therefore, magnetic susceptibility imaging of high spatial resolution will give more detailed information during the process of MNP-aided diagnosis and therapy. In this study, we present a novel spatial magnetic susceptibility extraction method for MNPs under a gradient magnetic field, a low-frequency drive magnetic field, and a weak strength high-frequency magnetic field. Based on this novel method, a magnetic particle susceptibility imaging (MPSI) of millimeter-level spatial resolution (<3 mm) was achieved using our homemade imaging system. Corroborated by the experimental results, the MPSI shows real-time (1 s per frame acquisition) and quantitative abilities, and isotropic high resolution.


Low-income preseniors represent a vulnerable, often overlooked population facing multiple challenges related to finding and sustaining employment, limited financial resources, mental and physical health challenges, mobility issues, and ineligibility for pensions and benefits for seniors. These issues make finding suitable, affordable housing particularly challenging when compounded with limited affordable housing stock, thus increasing this population's risk for housing insecurity/homelessness. This qualitative, exploratory study examined subsidized housing issues for low-income preseniors from the perspective of subsidized housing providers (n = 16). Barriers for this population occurred within individual (limited financial resources; complex health, mental health, and disability issues; current unsafe/inadequate housing; and new immigrant status) and structural (strict age cutoffs, inadequate safe/affordable housing supply, lack of information about the housing and service needs of the population, and ineffective collaboration within the sector) domains. Policy changes at the provincial and federal levels related to income support, availability of affordable housing supports, and immigration are recommended.


Seventeen neuraxis tuberculoma cases diagnosed and treated at Hacettepe University Medical Central between 1965 and 1988 were reviewed. Thirteen of these patients were explored surgically and all except two who died received anti-tuberculous chemotherapy in the postoperative period. In four patients who received aggressive medical treatment without surgical intervention. this treatment led to regression of lesions which was monitored by sequential computed tomography (CT).


In India, Witness protection legislation was unquestionably necessary since it protects the lives, property, and family members of witnesses. Each of their statements is important because it has the power to alter the whole track of the case. Without their assistance, the Court would be unable to reach to a fair conclusion. Prosecution witnesses are pressed and encouraged to weaken or even destroy the prosecution process by whatever means necessary. Although, it is a harsh reality that the situation of witnesses in the current judicial system is deteriorating nowadays which is why The Scheme for Witness Protection was approved by the Supreme Court on December 5, 2018. Also, The Law Commission of India, in different reports, has underlined the difficulties that witnesses experience during the trail process and has urged that a complete strategy on protection of witnesses be incorporated. However, the scheme fail short of standards several issues, such as online intimidation, financial issues, etc. The objective of this study is to explore the concept of Witness Protection Scheme, 2018, and to highlight the challenges that witnesses face in the judicial system, as well as to study at witness protection in India.

Abstract The possibility of maintaining a group of pico-satellites in a bounded formation, using very low power electric propulsion, is presented. A model predictive controller is used to develop a simple control scheme that avoids the need for on-line orbit determination. The control law, verified using a high fidelity propagator, is capable of maintaining a group of pico-satellites within a 1500 km region at an average ΔV of 2.5 m/s per month. In order to reduce the power requirements of the attitude and propulsion systems, a combined control is utilized. Attitude accuracy is shown to be better than 0.5 deg. The combined attitude-orbit control and the simplicity of the control law provide important advantage for implementation in a pico-satellite with extremely limited resources.

The variational method is applied to a step discontinuity in unilateral finline on the basis of a simplified description of the finite modes, as modes of a symmetrical finned waveguide. A prudent choice of the trial field in the electric and the magnetic formulations allows the derivation of economical simple equivalent circuits with frequency-independent elements over a full waveguide band for a broad range of practical step ratios. >


Overview Whereas the climate agenda includes both the need for climate mitigation and climate adaptation, these two topics are usually considered as independent in political practice: mitigation policies focus on the decarbonisation of industry, agriculture and services, whereas adaptation measures consists in planning and carrying out necessary investments (e.g. dykes). However, climate adaptation will have an impact on GHG emissions, hence on climate mitigation. For the residential sector, previous literature has found that positive temperature shocks increase US residential electricity consumption. This suggests that climate change adaptation could increase GHG emissions from electricity consumption. This research goes beyond previous analyses by evaluating which drivers would explain the relationship between climate change and US residential energy use. We look at the alterations and improvements to housing associated with climate shocks – including but not limited to air-conditioning – and correlate these changes with both gas and electricity consumptions. Then resorting to a long-term simulation, we find that climate change is likely to increase residential electricity consumption. However, this surge in electricity consumption could be more than compensated by a parallel decrease in gas consumption. All in all, total energy consumption (adding gas and electricity consumptions) could decrease due to adaptation to climate change, but not necessarily greenhouse gas emissions. Electricity generation in the US is carbon-intensive so that the predicted shift from gas to electricity could sustain greenhouse gas emissions in spite of a total reduction in energy demand resulting from climate change. This puts pressure on decarbonising electricity generation.


It is proved that the Auslander algebra of an algebra A is a twisted double incidence algebra of some poset X if and only if A is the local algebra K[x]/(x) n if and only if X is linearly ordered.


Since J. L. Lagrange initiated in [18] the study of minimal surfaces of Euclidean
3-space in 1760, minimal surfaces in real space forms have been studied extensively by
many mathematicians during the last two and half centuries. In contrast, so far very
few results on minimal Lorentz surfaces in inde nite space forms are known. Hence,
in this paper we investigate minimal Lorentz surfaces in arbitrary inde nite space
forms. As a consequence, we obtain several classi cation results for minimal Lorentz
surfaces in inde nite space forms. In particular, we completely classify all minimal
Lorentz surfaces in a pseudo-Euclidean space Em
s with arbitrary dimension m and
arbitrary index s.

Welding of dissimilar materials in particular ceramics to metals is a technical challenge with attractive economical consequences. In this study a ceramic coating was processed by plasma transferred arc (PTA). ZrO2–7wt.%Y2O3 powders were deposited on low carbon steel plates and on Ni based alloys layers previously welded on a steel plate. Coatings were evaluated regarding the soundness and features of the metal/ceramic bond. Results showed that the pair ZrO2–7wt.%Y2O3 /metallic alloy played a major role on the quality of the processed surfaces determining the effectiveness of the bonding. The presence of Al in the Ni based intermediate layer was detrimental to the adhesion of the ceramic coating. Deposition of ZrO2–7wt.%Y2O3 on NiCrFe intermediate layers allowed for a metal/ceramic bond resulting on 3,0mm thickness coatings. Ceramic deposits exhibited cracks, whose features were altered after a stress relief treatment of the substrate (AISI 1020+NiCrFe layer) prior to the deposition of ZrO2–7wt.%Y2O3. Transverse section analysis revealed the presence of second phase particles in the ceramic coating and the diffusion of elements from the intermediate Ni based layer into the ceramic deposit.


This paper presents an investigation into the development of an intelligent neuro-active noise control strategy which accounts for both linear and nonlinear dynamics of the system. Multilayered perception neural networks with a backpropagation learning algorithm and radial basis function neural networks with an orthogonal forwad regression algorithm are considered in both the modelling and control contexts. A feedforward active noise control (ANC) structure is considered for optimum cancellation of broadband noise in a threedimensional propagation medium. An on-line adaptation and training mechanism allowing a neural network architecture to characterise the optimal linear controller and nonlinear system dynamics within the ANC system is developed. l%e neuro-adaptive ANC algorithm thus developed is implemented within a fro-field environment and simulation results verifying its performance in the cancellation of broadband noise are presented and discussed.


Abstract Older Americans are using the Internet to access health information. This study compared the accuracy and completeness of diabetes self-care information likely to be accessed searching the Internet with American Diabetes Association recommendations. A strategy based on common search engines, frequency of Web site identification and relevance to diabetes management was used. Information about diet was common, but no site offered the tools needed to create a specific dietary plan. The amount and quality of information accessed regarding other self-care management categories differed by site. Generally, the retrieved information was not incorrect, but rather incomplete. Older adults with diabetes must be made aware that Web sites should be used only as a possible adjunct to individualized, personal, professional education and therapy.

We give a short proof of a theorem of Handel and Mosher stating that any finitely generated subgroup of $\text{Out}(F_N)$ either contains a fully irreducible automorphism, or virtually fixes the conjugacy class of a proper free factor of $F_N$, and we extend their result to non finitely generated subgroups of $\text{Out}(F_N)$.


This paper introduces a new type of suspended monorail developed in China with the advantages of both German and Japanese monorails. The FE (finite element) model of the bridge is built in Ansys and coupled with the multibody dynamic model of the vehicle in the UM (Universal Machine). software. FIALA formula is used to construct the tire model. Then, the vehicle-bridge coupling system of the new type suspended monorail is set up and simulated with Park method. The result of the modal analysis and vehicle-bridge coupling simulation draw the same conclusion that the span of the stiffeners could result in the resonance of the vehicle system, which is due to the coupling of the frequencies of the natural modes of the car body and bogie with that for vehicle passing through stiffeners. Through the multibody dynamic simulation of the vehicle-bridge coupling system, the modes of the bridge at the frequencies of 5–10, 15–25 and 30–40 Hz are easily excited when the vehicle passes through the bridge. The three constraint modes and free modes of the bridge are similar in these frequency ranges.


Banks are special types of economic and financial institutions that specialize in various currency and credit loan businesses. They have always been regarded as the most important part of a country's real economy. It has a major issue related to the national economy and people's livelihood.  Production, operation and management activities and the healthy development of the financial industry are very inseparable from the coexistence of financial banks. Joint-stock banks are also a very important part of the bank. With the current rapid development of China's modern financial industry, the market for joint-stock banks  The competition is becoming more and more fierce. Bank efficiency is an important indicator to evaluate the profitability and competitiveness of each bank. Efficiency evaluation is of great significance to the sustainable development of banks.  Super-efficiency DEA is an important method to study the efficiency of companies. This paper uses the super-efficiency DEA method to study the efficiency of the top ten domestic joint-stock banks with scale efficiency indicators and technical efficiency indicators.  This research shows that during the epidemic period, reducing operating costs is of great significance to improving bank efficiency, getting rid of the shackles of business outlets, financial innovation through the Internet and big data, and allowing customers to enjoy banking services anytime and anywhere has gradually become the goal of major listed banks.
