The sedimentary processes of seamount regions are closely related to climate change and ocean evolution. The clay minerals, grain size and 14C ages of core SCS18-1, which was collected from the Beipo seamount in the northern South China Sea (SCS) were analyzed to discuss the provenance and paleoenvironmental conditions during the last deglaciation. The sediments of core SCS18-1 are dominated by clayey silt, which is mainly composed of illite (55.2~62.1%) and chlorite (17.1~22.5%), with subordinate kaolinite (9.5~12.6%) and smectite (7.3~15.1%). The illite chemical index and illite crystallinity indicate strong physical weathering conditions. The results of the end-member modeling algorithm (EMMA) suggest that the sediments of core SCS18-1 consist of three end-members containing EM1 (0.98 μm), EM2 (9.29 μm) and EM3 (44.19 μm), with average contents of 3%, 66% and 31%, respectively. The finest endmember represents fluvial mud, the middle and coarsest endmembers are considered fluvial fine silt and eolian dust, respectively. The mean grain size is mainly controlled by the coarser fraction EM3. Based on the clay minerals, grain size and SEM analysis, we can conclude that since the onset of the last deglaciation (16.1 ka BP), the sediments of core SCS18-1 mainly originate from fluvial input, and eolian material also contributed to the sediments. The clay mineral assemblages of core SCS18-1 are stable and originate mainly from Taiwan. Additionally, the Pearl River appears to be a secondary contributor of clay minerals. Further, the Luzon Islands only account for a small proportion. Major kaolinite and moderate illite and chlorite are thought to originate from the Pearl River, predominant illite and chlorite from Taiwan, and principal smectite from the Luzon Islands. Both the relative content of EM1+ EM2 and the illite chemical index effectively represent the variation of East Asia summer monsoon (EASM) strength. Meanwhile, the relative content of EM3 effectively represents the East Asian winter monsoon (EAWM) change. The material supply of core SCS18-1 is mainly controlled by solar radiation in the Northern Hemisphere.

This paper introduces the background,aims,and content of the journal Hohai Monthly,which was launched by the first hydraulic college in China,Hohai Civil Engineering School( now Hohai University),in November 1917. The journal's historical status in the scientific and academic community and social influence are examined. The study shows that the journal is the longest-running hydraulic scientific and technical periodical in China. Development of an excellent group of authors has been the greatest contribution of Hohai Monthly to Chinese social development. Some articles published in previous decades of the journal still have academic value. Hohai Monthly inherited and carries forward a concept of serving the national interest through scientific inquiry and industrial development,as well as the goals of scientific rigor,realism,exploration,and innovation.


One of the key issues in mobile communication system is how to predict the number of calls per each cell. It is an important parameter and usually assumed as random Poisson value. For effective management of cellular network, the average number of calls should be traced and the changes in the numbers need to be promptly detected. In this paper we propose an algorithm detecting the changes in the demands of the users using the technique proposed for point-of-change problem based only on the number of call arrivals. Computer simulation reveals that the proposed method can effectively detect the discord, and the developed model is very accurate as showing mostly less than 1% differences.


In Oman, it been found that there is no authorized system for blood bank donation, which can make this donation easy, fast and updated. In some hospital still using excel sheet in computer and they contact people by call or SMS in emergency case. This paper discussed the possibilities of implementation a full network for Oman hospital and mobile application that, can be used as a joint washer between the hospital and donor. This application will be uploaded in google play store and it can be downloaded by anyone and there is website also for whom using computer. It will work as a coordinator between the central blood bank in Muscat (Basher) and donors in all over the country.


A database of 6272 municipal work records collected over a 31 month period were analyzed to establish performance standards for various types of tree maintenance. Man-hours required for tree removal, trimming and stump removal are presented. Interactions between man-hours required, diameter class, season, overhead electric wires and species were examined. Diameter class influenced all work types. Season influenced tree removal and stump removal. Overhead electric lines influenced the trimming operation. Tree species did not influence any of the work types studied.


Misuse of caller ID spoofing combined with social engineering has the potential as a means to commit other crimes, such as fraud, theft, leaking sensitive information, spreading hoaxes, etc. The appropriate forensic technique must be carried out to support the verification and collection of evidence related to these crimes. In this research, a digital forensic analysis was carried out on the BlueStacks emulator, Redmi 5A smartphone, and SIM card which is a device belonging to the victim and attacker to carry out caller ID spoofing attacks. The forensic analysis uses the NIST SP 800-101 R1 guide and forensic tools FTK imager, Oxygen Forensic Detective, and Paraben's E3. This research aims to determine the artifacts resulting from caller ID spoofing attacks to assist in mapping and finding digital evidence. The result of this research is a list of digital evidence findings in the form of a history of outgoing calls, incoming calls, caller ID from the source of the call, caller ID from the destination of the call, the time the call started, the time the call ended, the duration of the call, IMSI, ICCID, ADN, and TMSI.


We are developing autonomous, flexible control systems for mission-critical applications such as Uninhabited Aer ial Vehicles (UAVs) and deep space probes. These applications require hybrid real-time control systems, capable of effectively managing both discrete and continuous control lable parameters to maintain system safety and achieve system goals. Using the C IRCA architecture for adaptive realtime control systems (Musliner, Durfee, & Shin 1993; 1995; Muslineret al. 1999), these controllers are synthesized automaticallyand dynamically, on-line, while the platform is operating. Unlike many other AI planning systems, C IRCA's automatically-generated control plans have strong tempor al semantics and provide safety guarantees, ensuring that the controlled system will avoid all forms of mission-critical failure. To support on-line reconfiguration, C IRCA uses concurrently-operating planning (controller synthesis) and control (plan-execution) subsystems. The Controller Synthesis Module (CSM) uses models of the world (plant and environment) to automatically synthesize hard real-ti me safety-preserving controllers (plans). Concurrently a se parate Real-Time Subsystem (RTS) executes the controllers, enforcing response time guarantees. The concurrent operation means that the computationally expensive methods used by the CSM will not violate the tight timing requirements of the controllers. At the last AIPS workshop on model-theoretic approaches to planning, we discussed how the C IRCA CSM used a model-checker to plan C IRCA's hard real-time controllers (Goldman, Musliner, & Pelican 2000). In this approach, our forward (Musliner, Durfee, & Shin 1995) or divide-and-conquer (Goldman et al. 1997) planning search used an external model-checking program 1 to verify the correctness of the plan. The verifier was used incrementally on plan fragments, after each decision during plan constructi on. We found that the verifier was the primary bottleneck in this architecture. Accordingly, over the past two years, ou r efforts have concentrated on improving the performance of

Objective To compare the clinical effects of patient-controlled epidural analgesia(PCEA) or nitrous oxide inhalation analgesia.Methods A total of 360 single-fetal primiparas of vagina-deliverying were randomly divided into three groups with 120 cases each.When utero-cervical was opened about 3 cm,the patients in group P were given PCEA with 2 μg/ml fentany and 0.11% ropivacaine and those in group N received inhalation of 50% nitrous oxide in 50% oxygen.Results A satisfectory delivery analgesia was obtained in both groups with shortened labor process,decreased rate of cesarean section or instrument labor and side effects on the fetal and neonate,without increase of postpartum hemorrhage.All the primiparas could take off-bed activity.The active phase of group P was(129±42) min,which was shorter than(169±44) min in group N(P0.05).Conclusion Compared with nitrous oxide inhalation,PCEA is more effect and suitable for labor analgesia.


Although executive coaching has become increasingly popular in the corporate world for the last 2 decades, there have been few empirical studies on how the match between coach and coachee affects the coaching relationship. The purpose of this study was to examine the effects of gender similarity and perceived similarity on executive-coaching effectiveness, as reflected in the improvement in attitudinal and behavioral outcomes (i.e., self-awareness, career satisfaction, organizational commitment, and supervisorrated task performance). Study participants (68 coach-coachee dyads) were drawn from the clients of 4 Israel-based firms that provide executive coaching. Overall, the coachcoachee match had little significant effect on coaching outcomes. More specifically, gender similarity and perceived similarity had no significant effect at all on career satisfaction and organizational commitment. However, we found gender similarity had a significant relationship with the change of coachee's self-awareness. That is, male executives with female coaches responded that their self-awareness was not improved as a result of coaching. Additionally, the more coaches perceived similarity with coachees, the higher their supervisor-rated task performance. Since, unlike a mentoring relationship, executive coaching has more specific goals and a highly structured process, it appears to be unnecessary for HR/OD practitioners to be concerned about coach-coachee matching based on similarity (gender or overall perception).

Summary A 15 year old appaloosa mare was referred to the equine clinic with signs of hepatic insufficiency. Serum biochemical findings included hyperbilirubinemia and elevated activities of most of the liver specific enzymes. The ultrasound examination of the liver revealed several dilated hepatic ducts. Within one of these an echogenic structure was visualized and interpreted as cholelith. Based on these findings the diagnosis cholelithiasis/ cholangitis causing hepatic insufficiency was made. After ten days of therapy with steroids and six days of therapy with antibiotics respectively, the mare left the clinic in good general condition. Three years later the mare was again referred to the clinic showing the same acute symptoms of hepatic insufficiency and elevated serum activities of the liver specific enzymes. At first she responded well to the steroid therapy but after six days she started to suffer from laminitis and therefore was euthanized. The post mortem examination revealed a markedly dilated common bile duct (Ø 7 cm), which was obstructed by an orange coloured, smooth-fibrous textured cholelith of loamy consistence. The analysis by infrared spectrography revealed that the concrement had the same composition as feces. Unlike the majority of the calculi in horses no mineral components could be detected. As for the ethiopathogenesis we hypothesize that the cholelith formation through reflux of ingesta into the biliary system (therefore its name "enterocholelith") was the underlying problem and the cholangitis and the hepatic insufficiency the consecutive problem.


Introduction The coming of the information technological repertory has been understood as the phenomenon compared to the seas around Reformation Europe busy with a huge number of possibilities. One of the possibilities is that of being in virtual pocket of anyone on earth. The World Wide Web becomes a place offering a chance for tasting. Everyone comes in and out, with or without downloading and unzipping electronic materials, wandering around the labyrinth with the enchantment of being taught with texts and icons. 1 The rise of information technology seems to be a good chance for developing countries to find a new way to inculcate the sense of citizenship, with the understanding that this kind of brand new technology broaders the conceptual horizon of people and encourages the spirit of exploration.


Due to growing power density, on-chip temperature increases rapidly, which has hampered the reliability and performance of modern real-time systems. This paper studies how to minimize the peak temperature of real-time systems under hard real-time constraints with periodic thermal management. A closed-form representation of the peak temperature for such a periodic scheme is derived to tackle this problem. Based on this closed form and the arrival curve model, one offline approach and one online approach are proposed to minimize the peak temperature for a given event stream. The offline one does thermal optimization in design phase and introduces negligible runtime overhead. The online one computes dynamic power-control schemes which are adaptive to actual event arrivals and execution states. We conduct experiments on a real single-core processor and compare our approaches to two existing works. The temperature results measured from a physical thermal sensor demonstrate that the achieved maximal and average temperature reductions are 5[Formula: see text]K and 2.6[Formula: see text]K, respectively.


BACKGROUND
Diagnostic criteria of vestibular migraine (VM) by the Bárány classification consists of complex combinations of characteristics of dizziness: episodes, intensity, duration, migraine according to International Classification of Headache Disorders (ICHD), and migraine features accompanying vertigo. The prevalence according to strictly applied Bárány criteria may be much lower than preliminary clincal diagnosis.

OBJECTIVE
The purpose of this study is to investigate the prevalence of VM according to strictly applied Bárány criteria among dizzy patients who visited the otolaryngology department.

METHODS
The medical records of patients with dizziness from December 2018 to November 2020 were retrospectively searched using a clinical big data system. The patients completed a questionnaire designed to identify VM according to Bárány classification. Microsoft Excel function formulas were used to identify cases that met the criteria.

RESULTS
During the study period, 955 new patients visited the otolaryngology department complaining of dizziness, of which 11.6% were assessed as preliminary clinical diagnosis of VM in outpatient clinic. However, VM according to strictly applied Bárány criteria accounted for only 2.9% of dizzy patients.

CONCLUSION
The prevalence of VM according to strictly applied Bárány criteria could be significantly lower than that of preliminary clinical diagnosis in outpatient clinic.

Non-evaporating diesel sprays are simulated using sub models given in Fluent software. Meshing of the CFD model is done using Gambit software before transmitting it to Fluent software. The modeling is carried out using cold bomb conditions under variable gas pressure, density, nozzle diameter and fuel injection pressure, but maintaining gas temperature as atmospheric. The simulated penetration rate and spray tip velocity are compared with existing experimental data. An excellent match is found between simulation results and published correlation. The CFD simulation is found to be highly dependent on injection parameters and operating conditions.

Lui et al. performed a randomized trial to compare endoscopic variceal band ligation (EVL) with pharmacological treatment, using propanolol (PPL) or isosorbide mononitrate (IMN), for primary prevention of esophageal variceal bleeding. A total of 172 cirrhotic patients with Grade II–III esophageal varices were randomly assigned to receive either esophageal banding (44 patients) or pharmacological monotherapy with PPL (66 patients) or IMN (62 patients). The main endpoint evaluated was primary hemorrhage. Bleeding outcomes were calculated as 2-yr actuarial risks. Eradication of varices was defined as complete absence of varices or a regression to Grade I varices. EVL sessions were performed on a schedule of biweekly endoscopies and band ligations until eradication was achieved. Varices were eradicated after a mean of 3.1 ± 2.5 endoscopy sessions. PPL administration was started at a dose of 40 mg b.i.d. and increased incrementally every 3 days to a target dose of 160 mg/day. IMN dosage began at 20 mg b.i.d. and was increased after 3 days to a target dose of 80 mg per day.Two-year actuarial risks for primary variceal bleed were 6.2% for the EVL group, 19.4% for the PPL group, and 27.7% for the IMN group. One patient in the EVL group had a complication consisting of perforation of the upper esophagus secondary to insertion of the overtube. Of patients in the PPL group, 45% complained of adverse effects from treatment, resulting in a 30% withdrawal rate. Of IMN-receiving patients, 42% reported adverse effects, causing a 21% withdrawal rate. The most often encountered adverse effects of pharmacological monotherapy include breathlessness, headache, and fatigue. The only statistically significant difference between therapies showed less variceal bleeding with EVL when compared with IMN therapy. No statistical significance was achieved when comparing EVL with PPL or PPL with IMN. Pharmacological monotherapy produced a considerable adverse effect profile. Significantly fewer treatment withdrawals were observed with EVL compared with pharmacotherapy (p = 0.00).The authors concluded that EVL was as effective as PPL and more effective than IMN in prophylaxis of first variceal bleed in patients with esophageal varices. The authors suggested that EVL be considered as first-line therapy alongside PPL monotherapy in prevention of first variceal bleed in cirrhotic patients, given the extensive adverse effects of pharmacotherapy resulting in withdrawal from treatment.


Escherichia coli are commonly found in the gastrointestinal tract of humans and other warm-blooded organisms. Since E. coli can be discharge through deposition of fecal material, it has become habituated to soil and water in the environment. Hence the present study was undertaken to isolate and identify E. coli from various environments (viz., cattle waste, piggery, poultry and sewage water) and to determine their antibiogram patterns to different group of antimicrobial agents. A total of 120 samples comprising cattle wastes (30), poultry droppings (30), piggery (30), sewage water/sediment (30) were collected from the Dakshina Kannada and analyzed for the presence of E. coli. Of total samples screened, 82 (68.3%) were found to be positive to E. coli and among the 82 E. coli strains, 25 were isolated from cattle wastes, 18 from piggery, 13 from poultry and 26 from sewage samples. The antibiogram pattern of these strains showed varied multi-drug resistance profile to the selected antibiotics. Of 82 strains, 19 (23.2%) were susceptible to all the antibiotics and 63 were resistant to at least one of the drug tested. The results from present study revealed the higher relative resistance pattern to the tested antibiotic among E. coli suggesting their potentiality in transferring MDR thereby posing public health concerns in treating problems.


Results of quantitative sound level measurements show that Upper Paleolithic parietal art sites sampled in France have unusually good sound reflection. The majority of art figures at those locations can be classified as Ungulata, i.e., hoofed mammals. Echoes of percussion noises (from clapping or stone tool making) can mimic hoofbeats. Flutter echoes sounding particularly like galloping occur at Angles-sur-l'Anglin, Rouffinac's Painted Ceiling, Oreille d'Enfer, Castlemerle and in the valley containing Cap Blanc, Laussel and Commarque. Carnivore art was found in contexts of locally decreased sound reflection: e.g., in Font-de-Gaume. The decibel level from Lascaux's Chamber of Felines is statistically less than the other portions of Lascaux at the p = 0.0001 level. Both rock art and sound reflection occur world-wide, typically in caves and canyons, and art sites in Australia, Asia and America have been heard to reflect sound. Together with the knowledge that ancient cultures considered echoing a mysterious phenomenon, these observations suggest an acoustical motivation for the content and context of at least some rock art. This theory of sound reflection as a motivation for rock art is not inconsistent with either the hunting magic theory nor Leroi-Gourhan's observed pattern of sanctuary decoration.


Summary. A reliable, reproducible, rapid and specific test for the pathogenicity of Brenneria nigrifluens , the causal agent of shallow bark canker of Persian walnut, was developed. When the mesocarp of immature walnut fruits was infiltrated by syringe with bacterial suspensions (10 8 cells mL -1 ) of B. nigrifluens , necrosis and reddish brown exudates started to appear at the inoculation sites, as early as 2 days after inoculation. No symptoms were detected in control fruits or in fruits inoculated with other bacteria frequently associated with walnut cankers. This pathogenicity test saves time and space when compared with the plant stem inoculation technique, in which the canker symptoms do not appear until at least 1 month after inoculation.


We study asymptotic properties of the p-adic version of a fractional integration operator introduced in the paper by A. N. Kochubei, Radial solutions of non-Archimedean pseudo-differential equations, Pacif. J. Math. 269 (2014), 355–369.


Background/Aims: Little is known about the complex anatomy of right ventricular (RV) torsion in the general population. This study was designed to assess RV's global and segmental torsional motion in subjects without cardiac pathologies.Methods: We used the Vivid 7 ultrasound system (GE Healthcare, Chicago, IL, USA) to acquire parasternal short-axis views of the RV at the basal and apical levels, and analyzed global and segmental torsion using a 2D speckle tracking algorithm in EchoPAC workstation (GE Healthcare, Wauwatosa, WI, USA).Results: Forty-eight individuals (44 ± 17 years, 54% male) were included, with either normal left ventricular diastolic function (group I, n = 40) or grade I diastolic dysfunction (group II, n = 8). Group I showed global peak systolic torsion of 9.0 ± 6.6 degrees with higher segmental torsion in the mid-interventricular septum (IVS) than in the anterior walls (p = 0.001). Global RV torsion showed a very strong positive correlation with apical rotation (r = 0.91, p < 0.001). Group I exhibited higher segmental torsion in the anterior-IVS and mid-IVS walls than group II (9.8 ± 7.1 vs. 3.5 ± 9.6 degrees, p = 0.036; 10.4 ± 9.1 vs. 2.4 ± 12.3 degrees, p = 0.038, respectively).Conclusions: Analysis of RV segmental torsion was feasible using a 2D speckle tracking algorithm. Apical rotation can be used as a simplified index of global RV torsion. Further studies are needed to evaluate the clinical impact of RV torsion in various pathologies.


We fabricated sheets with high thermal conductivity in a way that required less filler. Our approach is as follows: (1) we used core–shell spherical microbeads as the thermally conductive filler; (2) we developed cellulose/h-boron nitride (BN) core–shell spherical microbeads using phase separation of a cellulose xanthate aqueous solution (viscose); (3) we hybridized the cellulose/h-BN core–shell microbeads with epoxy resin using compression molding. This process reduced the amount of h-BN required because the microbeads efficiently formed thermally conductive pathways among the shells in the insulating resin. The thermal conductivities of the resulting sheet in the thickness and in-plane directions were 10.6 and 15.6 W m−1 K−1, respectively, using only 48.5 vol% h-BN. In contrast, the thermal conductivities of the composite sheet with 75 vol% of naked h-BN particles were 6.31 and 22.9 W m−1 K−1 in the thickness and in-plane directions, respectively. This large difference resulted from the anisotropic structure of h-BN. The changes in thermal conductivity with h-BN content were inconsistent with percolation theory, when using the cellulose/h-BN core–shell microbeads as a filler. The thermally conductive sheets fabricated with microbeads exhibited thermal conductivities several times greater than that of sheets fabricated with naked h-BN. This indicated that thermally conductive pathways had formed in the insulating resin.


A mathematical model for the motion and evaporation of droplet were given to investigate the evaporation characteristics of different physical and chemical parameters liquid drop in low temperature flue gas with the relative velocity and temperature.The average temperature and diameter of droplet during its evaporation process were analyzed,also the influence of the droplet diameter and velocity and the flue gas velocity.The results show that the temperature variation processes are different for bicomponent droplets and single-component droplets under the same conditions,but their diameter variation are same.The sequence of the evaporation rate form biggest to smallest is water drop,acid and salt drop and alkalescency solution.The diameter of droplet with different physical and chemical parameters investigated reveals the same index change rule,within the range of temperature and velocity.The smaller the diameter of droplet is,the easier it reaches the flue gas velocity,and the less is the influences of the initial drop velocity to the droplet life time.The effects of change of flue gas velocity and liquid drop initial velocity on evaporation rate of droplet are small.


Carp were maintained for a month in well-oxygenated water fertilized with organic manure. During the experiment the thickness of the epidermis increased from 140 to 180 urn. Fish from pulluted water were dark, an adaptation to the dark, turbid water. The number of cytoplasmic extensions from the dermal pigment cells increased continuously from 6 per unit length in control specimens to over 80 in the experimental specimens at the end of the month. Apart from background adaptation, this activity of the pigment cells may be a stress reaction. Holocrine secretion of mucous cells was pronounced, with a progressive reduction on the first day after the transfer, to almost total disappearance of this cell type from the epidermis after 3 days. A thick mucous coat became visible on the outside of the epidermis. Eight days after the transfer, a slightly subnormal mucous cell count was observed, indicating the development of newly differentiated mucous cells. This subnormal cell count lasted until the end of the experiment. The pavement cells actively secreted glycocalyx, while newly differentiated pavement cells with still-intact secretory granules replaced the exhausted cells at the epidermis surface throughout the experimental period. Granulocytes, both baso- and neutrophilic, as well as macrophages, infiltrated the epidermis; despite the high bacterial count in the water, no bacteria were observed either inside the skin or entangled in the mucous coat.

The results of this study indicate that: 1) The application of job identification has not been carried out optimally due to the absence of SOPs that bind Board of Islamic Boarding Schools. 2) Summary of work at the Riyadus Shalihin Islamic Boarding School in Bandar Lampung has been formulated and implemented but often overlaps. 3) Duties and responsibilities at the Riyadus Shalihin Islamic Boarding School in Bandar Lampung have not been carried out properly and in accordance with the job description. 4) The authority at the Riyadus Shalihin Islamic Boarding School in Bandar Lampung has been carried out properly in accordance with the authority given by the leadership to the teaching and caregiver staff. 5) Work standards at the Riyadus Shalihin Islamic Boarding School in Bandar Lampung do not exist. 6) The working conditions of the Riyadus Shalihin Islamic Boarding School in Bandar Lampung do not provide a sense of comfort because they work without clear rules/work standards or SOPs. 7) Job specifications at the Riyadus Shalihin Islamic Boarding School in Bandar Lampung do not match the diploma background.


The present study examines the types and the causes of code-switching and code-mixing of Japanese language learners participated in Hiroshima University winter courses conversation. The study used case study design with qualitative methods. The data in this study was a recorded conversation of seven participants of Hiroshima University winter course program, who had studied Japanese for three to four years, and one Japanese native speaker as a tutor. The results show that there are twenty-five data found on internal code-switching, twenty-four data of external codeswitching, one data of inner code-mixing, and thirty data of outer code-mixing. From these data, the identified factors that caused code switching were: (1) speaker, (2) speech partners, (3) situation, and (4) discussion topic. While the factors that caused code-mixing were: (1) vocabulary mastery, (2) speakers' language habit, and (3) the purpose of using language variations.


Field experiments were carried out in stands of gorse (Ulex europaeus L.) in New Zealand to determine the conditions under which fires would both ignite and spread. Research and operational experience in shrub fuels suggest that there is a clear difference between conditions that support ignition only (fuel ignites but does not spread beyond a single bush or clump) and conditions that are conducive to fire spread (fuel ignites and develops into a spreading fire). It is important for fire management agencies to be equipped with knowledge of these thresholds, because the different conditions require different levels of preparedness and response. Results indicate that the major variable influencing both fire ignition and fire spread development in gorse is the moisture content of the elevated dead fine fuel layer. Fires were observed to spread successfully in this elevated fuel layer only, independently of the surface fuels and the near-surface fuels. Elevated dead fuels failed to ignite at a moisture content of greater than 36%, and ignition only resulted in a spreading fire at moisture contents below 19%. The results correlate well with field observations and fire practitioners' experience in these fuels, and provide reliable guidelines for fire management planning.


Multimotor drive system is widely applied in industrial control system. Considering the characteristics of multi-input multi-output, nonlinear, strong-coupling, and time-varying delay in two-motor drive systems, this paper proposes a new Smith internal model (SIM) control method, which is based on neural network generalized inverse (NNGI). This control strategy adopts the NNGI system to settle the decoupling issue and utilizes the SIM control structure to solve the delay problem. The NNGI method can decouple the original system into several composite pseudolinear subsystems and also complete the pole-zero allocation of subsystems. Furthermore, based on the precise model of pseudolinear system, the proposed SIM control structure is used to compensate the network delay and enhance the interference resisting the ability of the whole system. Both simulation and experimental results are given, verifying that the proposed control strategy can effectively solve the decoupling problem and exhibits the strong robustness to load impact disturbance at various operations.


Purpose. Although a major part of the anterior surface of the eyeball is formed by the sclera, there is little confirmed data on topography of the sclera compared to the cornea. The goal of this paper was to provide an update of relevant literature published on anatomy and topography of the anterior sclera. Methods. A systematic literature search was conducted in PubMed using the key words "scleral" and "topography." 66 of the 310 papers dealt with the topic and were used for this present review. In addition, 5 articles from the Germanlanguage non-peer-reviewed literature were included. Results. Several studies have demonstrated the utility of modern measurement and examination techniques, such as optical coherence tomography (OCT), Scheimpflug imaging, or Fourier-based profilometry in the assessment of scleral parameters. These allow a more comprehensive understanding of the structure and shape of the anterior sclera, simplified contact lens selection, prediction of lens fit, and assessment of changes in scleral topography. The shape of the sclera can be influenced by factors such as age, refraction, accommodation, convergence, thickness, stiffness, modulus of elasticity, intraocular pressure, keratoconus and contact lens wear. Conclusion. A comprehensive understanding of the biometric properties and topography of the sclera of the anterior segment of the eye is an essential component for both the design and fitting of scleral as well as soft contact lenses. Keywords Sclera, topography, anatomy, Scheimpflug, profilometry, optical coherence tomography

According to the conserved sequence of PCV2 published in GenBank, a pair of primers for amplification of PCV2 specified fragment was designed and a PCR assay for PCV2 detection was established. The results showed that the PCR was sensitive and specific, and useful to detect the clinic samples. It was helpful for clinical diagnosis and epidemiologic survey of PCV2.


Studies on mechanical properties of Ni-Mn based Heusler alloys are lacking which limits their use for practical applications. In the present work, nanomechanical analysis of ternary Ni-Mn-Sn and Ni-Mn-Al Heusler alloys were performed using nanoindentation test. Dense pellet specimens of selected 15 hr mechanical alloyed ball milled powder samples were prepared by consolidation, sintering and polishing processes. Load-displacement curves were obtained from a typical nanoindentation test by penetrating the indenter tip into the prepared pellet specimens surface with a prescribed loading and unloading data using Oliver-Pharr method of analysis to determine elastic modulus and hardness. The average elastic modulus and harness of Ni-Mn-Al alloy found more than Ni-Mn-Sn alloy. Also, the effects of sintering temperatures on the densities of pellet specimens were observed which showed that higher sintering temperatures are required to achieve the homogeneity and reduce the porosity of specimen.


Using fluorescent microthermal imaging we have investigated the origin of 'two-step' behavior in I–V curves for a current-carrying YBa2Cu3Ox superconducting bridge. High resolution temperature maps reveal that as the applied current increases the first step in the voltage corresponds to local dissipation (hot spot), whereas the second step is associated with the onset of global dissipation throughout the entire bridge. A quantitative explanation of the experimental results is provided by a simple model for an inhomogeneous superconductor, assuming that the hot spot nucleates at a location with slightly depressed superconducting properties.


24 8and 9-year-old children of each sex and at low and high levels of anxiety as measured by the Test Anxiety Scale for Children (N = 96) were divided equally into 6 experimental groups according to the type of pretraining (success, failure, or no pretraining experience) and reinforcement condition (social reinforcement or nonreinforcement from 1 of 2 males) in a subsequent angle-matching task. The Ss' achievement expectations were assessed prior to and following the experimental task. Major results were: (a) Following social reinforcement, expectations increased, the effect being stronger for girls than boys. (b) Following nonreinforcement, achievement expectations remained stable for both sexes. (c) Initial achievement expectations correlated negatively with test anxiety for girls. (d) Change in achievement expectation correlated positively with test anxiety for boys in the social reinforcement condition. The sex difference in the facilitating effects of social reinforcement on achievement expectations was considered as being part of a possible Sex of S by Sex of E interaction. It is suggested that sex differences in learning and cognition may be greater than has been recognized. Theorizing on the causes of the negative relation between a high level of test anxiety and children's achievement behaviors and intellectual


High power sodium vapor lamps (up to 2-kW) are widely used for illuminative purposes. Foremost application of these lamps is in the large scale environment lighting such as highways. These lamps are used with appropriate reflectors control the light propagation direction and pattern. Accomplishment of proper characteristics of such lamps, e.g., ignition and continuity of the lamp operation requires a drive circuit, known as ballast, which generates the applied voltage to the plasma tube. Two types of ballasts are mainly used in the industries: electric (conventional circuit using chuck) and electronic ballasts. Different characteristics of these two types of ballasts affect the plasma behavior and consequently the emitted light properties. In this paper, the effects of electronic ballast, such as high frequency harmonics, controlled power factor, have been investigated and compared with conventional approaches. A typical plasma tube which is commonly used in high power sodium vapor lamp structures has been considered without any reflectors. Plasma channel of the lamp has been modeled by a finite element method, solving particle continuity, momentum conservation and thermal balance equations in gaseous medium, in 2-D geometry. Cylindrical symmetry of the lamp structure has been applied. As a result of the simulations, light spectrum distribution is achieved by use of electron and ion density and velocity distribution along the plasma channel. These parameters have been compared at two different cases: conventional electric and electronic ballasts.


Foreign linguists have remarked that the Philippines is an excellent laboratory to study firsthand such sociolinguistic realities as multilingualism, languages in contact, language policy formulation, language attitudes, and the spread of English. Depending on which linguist or reference work is consulted, the country of 80 million has 80 to 120 languages, of which 10 are spoken by more than 500,000 people. Spanish was the language of the first colonizers but no more than 2% of Filipinos spoke it at the end of the 300 years that the Spaniards ruled the country (1565-1898). And yet Americans were able to spread their language to 27% of the population, according to the 1939 Census, mainly through the public school system that they established in 1901, at practically the very start of their rule (Gonzalez 1997). Fluctuations in the fortunes of the national language (Filipino, formerly Pilipino, based on Tagalog) have depended on the anti-Tagalog or the pro-English sentiments of common people as well as lawmakers, but are also conditioned by the strength of anti-imperialism or pro-globalization movements around the world. The Bilingual Education Policy, first implemented in 1974, which mandated the use of the national language as the medium of instruction for the relatively culture-loaded subjects of social studies, art, and music, and English for the relatively culture-free subjects of science and mathematics, has been variously praised for spreading proficiency in Filipino across the islands and blamed for the deteriorating quality of the English spoken by the population. Every once in a while, the language policy is revisited and proposals aired to change it. For some time now, however, everything has been quiet on the language front, except for loud expressions of continuing concern over the poor English used by students at all levels, by professionals, and even by print and broadcast media practitioners. Some of the anxiety over the quality of the English spoken and written in the Philippines is warranted because, for instance, lack of agreement between a subject and a verb when these elements are placed just beside each other, or lack of agreement in gender and number between a pronoun and its antecedent, cannot be condoned, especially in print media where such errors are sometimes found. But surely, some of the anxiety is misplaced if one is aware of the changes that inevitably take place in a language that has been transplanted to a new place. If the language is widely learned and is used for many functions and in many domains,


Abstract The presence of Listeria rods, especially Listeria monocytogenes, in the environment and food products, contributes each year to death of both humans and animals. The ability of bacteria to lead a saprophytic and parasitic existence as well as insensitivity to many physicochemical factors greatly facilitates the spread and guarantees access to a wide range of vulnerable organisms. Although the factors predisposing to infection result in a relatively low incidence of disease, infections are characterized by high mortality and often the need of hospitalization. The disease most often manifests itself in the form of bacteremia, meningitis and encephalitis as well as perinatal infections. The way Listeria spreads in the body contributes to the identification of new types of the disease. Recent studies on the acquisition of pathogenicity traits, dose and development of antibiotic resistance as well as numerous reports on incidence of these bacteria and the epidemics they caused, have led to more efficient monitoring of the pathogen . The qualification of the disease has also changed and, currently, listeriosis is considered a contemporary threat to life and health. 1. Introduction. 2. Genus Listeria.

Conjugated meningococcal capsular saccharide, but is introduced into immunization schedules in the near future, the phenomenon of "carrier suppression", must first be addressed. This, when a plurality of conjugate used is especially true. In the present invention, tetanus toxoid, even when a plurality of meningococcal conjugates are administered at the same time, and previous immunogen forms (e.g., DTP vaccines) or previous carrier protein (e.g., Hib or pneumococcal even if the patient is exposed to previously with respect to the carrier protein in the form of conjugate vaccines), it is used as a carrier protein. The present invention provides a method for immunizing a patient. The method includes the step of administering multiple conjugates of meningococcal capsular saccharides, each conjugate comprises a tetanus toxoid (or derivative thereof) carrier protein and the capsular saccharide, the patient, tetanus toxoid in has been pre-immunized.


2 is a promising anode material for sodium ion batteries owing to its two-dimensional layered structure and high specific capacity. But it still exhibits a poor cycle stability and limited rate capability for Na + storage because of its poor electrical conductivity and structural instability. In this work, MoS 2 /graphite composite is fabricated by mechanically delaminated and restacked MoS 2 and graphite to form two-dimensional composite layers. The graphite sheets will improve electrical conductivity and prevent the aggregation as well as structure collapse of the MoS 2 layers during charge–discharge process. The MoS 2 /graphite composite exhibits excellent Na + storage properties. It delivers a high discharge spe- cific capacity of 358.2 mAh/g at a current density of 100 mA/g in the first discharge process and with capacity retention of 68.1% after 800 cycles (retains 244 mAh/g). The average discharge specific capacities retain 250.9 and 225.4 mAh/g corresponding to the current densities of 100 and 10 0 0 mA/g, showing excellent rate capability. The improved electrochemical performance is attributed to the improved electrical conductivity and structural stability after composition of graphite sheets. The study demonstrates a new research strategy for improving sodium ion storage properties of MoS 2 . © 2017 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences.

Blood pressure readings were studied in 1356 women taking hormonal contraceptives. 53 cases (3.9%) showed an increase of blood pressure. The parameters of age parity previous history of pregnancy toxemia or hypertension are considered. An attempt is made to differentiate the effect of different types of steroids and the duration of therapy. In 21 cases therapy was stopped because of an increase in blood pressure; in 17 of these blood pressure then returned to the pretreatment level in 1 case it decreased but not to the level observed initially while 3 cases could not be followed up. Rise of blood pressure on a hormonal basis is discussed.(FULL TEXT)


The Food Supply Chain describes how raw materials are transferred from suppliers to manufacturers, distributers, retailers, and finally, to customers. Consumers are becoming increasingly concerned with how their food is sourced and produced in regard to the environment. The Green Food Supply Chain (GFSC) is gaining popularity in the United States (U.S.) as it integrates environmentally friendly and sustainable food production practices. Consumers are often unaware of the first step of the supply chain, which is food production. The different food production systems include Conventional, Organic, and Genetically Modified Organisms (GMO), and each has a different impact on the environment. In order to assess consumers' knowledge and preferences about their food's sources, 204 adult participants completed an online survey regarding this topic. The survey included demographic questions and general questions about their knowledge of and their beliefs regarding GMO food production and its impact on the environment. Almost half (48%) of participants believed that GMO food production has a harmful impact on the environment, while 31.4% had no knowledge of GMO food production and environmental impact. A 2 test showed a significant association between preference for non-GMO and individuals' beliefs on how GMO food production systems may impact the environment (2 (1) = 29.592, p = 0.001). Of the 98 participants who believed that producing GMO foods has a harmful impact on the environment, 75% preferred foods to be labeled as non-GMO. Almost 80% of participants affirmed that the impact a particular food production method has on the environment affects their food purchasing decisions all of the time or sometimes. Individuals' beliefs and knowledge of food production systems, and their possible impact on the environment, are important and influence demand. Therefore, consumers should be provided with more education and information about their food's


The utility model provides a tile packing device, which sequentially comprises a tile packing carton machine, a corner connector mounting machine, a carton folding machine, a packing and banding machine and a control device, and is characterized in that the tile packing carton machine comprises a carton positioning machine and a mechanism for positioning tile piles on cartons; the carton positioning machine comprises a rack, a carton taking mechanism arranged on the rack, and a conveying belt which is arranged on the rack and is far away from the carton taking mechanism. Compared with the prior art, the tile packing device has the advantages that the speed is quick, and meanwhile, drop points of the tiles dropping on the cartons are accurate.


In 1990, Earl Shriner, a released pedophile, raped a seven-yearold boy, severed the boy's penis, and left him to die. The public outrage that followed this horrific incident in Tacoma, Washington led to the passage of that state's Sexually Violent Predator ("SVP") law. The law provides for post-incarceration psychiatric commitment of sex offenders who suffer from a "mental abnormality or personality disorder" that makes them sexually dangerous. State officials deemed the legislation necessary to protect the public against individuals like Shriner whom they had been unable to detain under the state's involuntary psychiatric commitment standard following release from prison. Legislators believed that the adoption of a standard that specifically targeted sexual dangerousness while incorporating ambiguous mental impairment language would facilitate sex-offender commitment. They were right. In the first twelve years of enforcement, 164 individuals were committed under the law. But Washington is not alone. Fifteen states and the District of Columbia have enacted SVP statutes patterned closely on Washington's. As of the spring of 2002, some 2,229 individuals—virtually all of them male—were civilly


21st Century provides many challenges, especially for the world of education. Students are expected to acquire several skills that can support their lives in order to compete in the future. One important skill is creative thinking skills. Creative thinking skills are a way of thinking based on information to find solutions to a problem that is emphasized on the quantity, appropriateness and diversity of answers. Some observations show the low creative thinking skills of students because the empowerment of creative thinking skills is still lacking in learning in Indonesia. One solution that can be done in improving creative thinking skills is to choose the right learning model in this case the researcher uses the ERCoRe learning model. This study aims to look at the effect of the ERCoRe learning model on students' critical thinking skills. This type of research is quasi-experimental. Analysis of the data used is covariance analysis. Conclusions based on the results of the analysis there is an effect of 52,006 on the ERCoRe learning model while the conventional learning model is only 43,515 on students' critical thinking skills compared to conventional strategies.


The cyclic voltammetric behaviour of 2,2′-, 3,3′-, and 4,4′-azopyridine, and 2-, 3-, and 4-phenylazopyridine in CH3CN is compared with that of azobenzene. From the results obtained when CH3CN and PhCH2CO2Et are added to solutions of azobenzene and 2,2′-azopyridine in super-dry dimethylformamide it is concluded that the azopyridines and phenylazopyridines are reduced by a mechanism analogous to that of azobenzene, and that their dianions deprotonate CH3CN to give –CH2CN.


Objective To describe and analyze three unusual cases of Langerhans' cell histiocytosis of the temporal bone in adults. Study design Retrospective case review. Setting A tertiary referral center. Patients Three adult patients with progressive sensorineural or mixed hearing loss, vertigo, and tinnitus as presenting symptoms of Langerhans' cell histiocytosis of the temporal bone. Intervention Patients were evaluated by means of computed tomography and magnetic resonance imaging. All patients underwent complete surgical excision of the lesion via a transmastoid approach, extended to a translabyrinthine approach in one case. One patient with a multifocal disease underwent excision of a mandibular lesion 1 year later, followed-up by chemotherapy. Results The Langerhans' cell histiocytosis was located adjacent to or within the area of the endolymphatic sac region in all cases. The middle ear was spared. Hearing function was preserved in the two patients who had serviceable hearing preoperatively. No complication occurred. Conclusion Langerhans' cell histiocytosis of the temporal bone is centered on or adjacent to the endolymphatic sac. The fact that the endolymphatic sac plays an immunologic role in the inner ear suggests that the infiltration of the Langerhans' cell may derive from it.

A compound from the seeds of Descurania sophia (L.)Webb.ex Prantl was isolated by the column chromatography on silica gel and elucidated as quercetin-7- O - β - D -glucopyranosyl(1→6)- β - D -glucopyranoside by the physico-chemical characters and spectroscopic methods(NMR,ESI-MS).This is a new compound.


Despite increasing rates of entry, students with learning disabilities (LD) continue to face barriers to completing post-secondary education. Faculty attitudes and knowledge are important factors in supporting students with LD, yet little is known about faculty preparation. No valid, reliable, easy-to-administer inventory exists to assess the perceptions of faculty about their preparedness for the task of teaching students with LD. The Faculty Preparedness Questionnaire (FPQ) was developed to measure faculty perceptions of preparedness for teaching students with LD based on two factors: knowledge and attitude. For this study, 101 community college instructors completed the original questionnaire consisting of 22 items. After factor analysis, the 17-item FPQ was determined to be a reliable and valid instrument for the measurement of instructor attitudes and knowledge as components of their perceptions of preparedness. This research contributes to the current dialogue regarding best practice for inclusive post-secondary education.

This research contributes to the current dialogue regarding best practice for inclusive post-secondary education. The number of students with diagnosed learning disabilities (LD) attending postsecondary education institutions across North America has been steadily increasing over the past decade (Cortiella & Horowitz, 2014; Raue & Lewis, 2011; Standing Senate Committee on Social Affairs, Science and Technology [SSCSAST], 2011). Statistics indicate that despite increasing rates of entry, students with LD continue to face barriers to completing their post-secondary programs (Finnie, Childs, & Qui, 2012; Nichols, Harrison, McCloskey, & Weintraub, 2002; Raue & Lewis, 2011; SSCSAST, 2011). However, identifying and addressing barriers and providing adequate support to post-secondary students with LD have been associated with increased retention and Hansen, Dawson, & Specht 100 Exceptionality Education International, 2017, Vol. 27, No. 1 success (Burgstahler & Doe, 2004; Denhart, 2008). Students with disabilities have noted that faculty understanding of their learning needs is a key component to their success (Denhart, 2008; Getzel, 2008; Rao, 2004). Specifically, students with LD have described that faculty awareness about LD and faculty attitudes toward students with LD have affected their decisions to seek assistance, use accommodations, and persist with their post-secondary education (Denhart, 2008; Nichols et al., 2002; Tsargris & Muirhead, 2012). The incidence of LD in the general population is considered to be 5–10% (Learning Disability Association of Ontario, 2015; Kozey & Siegel, 2008). Although the number of individuals diagnosed with LD enrolled in post-secondary programs has been increasing at all institutions, students with LD are more likely to attend two-year or community college programs due to the applied nature of learning in these institutions (Cortiella & Horowitz, 2014; McCloy & DeClou, 2013; Rath & Royer, 2002; SSCSAST, 2001). Statistics in Ontario have indicated that approximately 13% of the overall student population at community colleges was registered with disability services and that nearly 40% of these students indicated that they had a LD (Government of Ontario, MTCU, 2011). Furthermore, some researchers have suggested that there are more students with LD than documented, due to the considerable number of students who choose not to disclose their LD or seek accommodations (Denhart, 2008; Gregg, 2007; Tsargris & Muirhead, 2012). In post-secondary education, students with LD must self-disclose their disability diagnosis and assessment information in order to gain access to accommodations. Classroom and assessment accommodations are arranged individually through the campus disability services office (DSO). Appropriate accommodations provide students with LD the opportunity to meet their learning potential and achieve academic results reflective of their intellectual abilities (Tsargris & Muirhead, 2012). The definition of LD most often used by DSO counselors is referred to as the "discrepancy definition," which states that a student with a LD demonstrates academic achievement below that expected for his or her IQ. This underachievement is the result of a number of disorders, which may affect the acquisition, organization, or use of information and is not explained by other factors such as motivation, language learning, sensory impairments, or low cognitive function (American Psychiatric Association, 2013; Learning Disability Association of Ontario, 2011; Logan, 2009). Confounding the statistics and definition of LD is the comorbidity of other disorders, such as attentiondeficit disorder and/or mental illnesses. These comorbidities occur frequently with LD; however, the numbers are unclear due to inconsistent methods of data collection and analysis (Learning Disability Association of Ontario, 2015). Our study focuses on faculty preparedness to teach students who have LD as their main diagnosis. Previous researchers have discussed the importance of faculty understanding the definition, the characteristics, and the needs of students with LD, as well as the negative impact that faculty misunderstandings have on student success (Denhart, 2008; Getzel, 2008). Denhart (2008) found the main reason that students hesitated to disclose their LD was fear of being misunderstood or misjudged by faculty. Given the increasing number of students with LD attending post-secondary institutions and the impact of faculty knowledge and attitudes on student retention and success, it is important to Assessing Preparedness to Teach Students with LD Exceptionality Education International, 2017, Vol. 27, No. 1 101 understand faculty perceptions of their preparedness to teach post-secondary students with LD. Preparation for Inclusion—Defining Knowledge and Attitude The importance of instructor preparation for teaching students with various types of disabilities in post-secondary education has been investigated in previous research (Burgstahler & Doe, 2004; Cook, Rumrill, & Tankersley, 2009; Getzel, 2008; Scott & Gregg, 2000). Numerous studies have explored the attitudes, perceptions, and practices of university and college faculty toward students with disabilities (Jensen, McCrary, Krampe, & Cooper, 2004; Lombardi & Murray, 2011; Murray, Wren, & Keys, 2008; Rao, 2004; Zhang et al., 2010), but these have not explicitly investigated faculty perceptions of their preparedness for inclusive classrooms in the post-secondary education sector (Hindes & Mather, 2007). However, there are several studies exploring the determinants of teacher preparation for inclusion of students with disabilities in kindergarten–Grade12 education (Hay, Smit, & Paulsen, 2001; Holdheide & Reschly, 2008; Jordan, Schwartz, & McGhie-Richmond, 2009; Sharma Forlin, Loreman, & Earle, 2006; Sze, 2009). In the current study, we have adopted the definition of prep


Poly(9,9-dipropargylfluorene) and poly(2-substituted-9,9-dipropargylfluorene)s (X = Ac, Br, NO2) were prepared by the palladium-catalyzed dehydrocoupling polymerization reaction of 2-substituted-9,9-dipropargylfluorenes. The thermal and optical properties of the polymers have been investigated. The diacetylenic functions in polymer main chain started to be thermally crosslinked in the range of 143–177°C. The photoluminescence spectra of polymers were in the range of 407–410 nm, which are corresponded to the photon energy of 3.05–3.03 eV. The quantum yield of poly(DPF-Br) is the highest value (55.84%), which means probably the contribution of electron-donating character of Bromine at the 2-position of fluorene.


The body while alive remains in homeostasis with the environment, after death the body enters a state of decomposition releasing cadaveric effluents, such as necrochorume, an ideal medium for the proliferation of infectious diseases, which can percolate in the soil up to the water table Studies on the problems caused by cemeteries to the environment and also the population are few topics addressed, it is possible that soil and groundwater in cemeteries may be contaminated by the frenestration of substances and toxic agents caused by the decomposition of bodies and thus causing impacts to the environment. public health. Therefore, the objective of this work was to analyze the factors associated with soil contamination: decomposition, treatment of corpses and funerary materials. Through a systematic review, data were obtained on materials and products used to preserve the body, the types of burials and the impacts caused. It was evidenced that the decomposition, treatment of corpses and funerary materials are associated factors not only to the contamination of the soil, but also of the waters through the groundwater and the atmosphere through the gases that are produced. In Brazil, government officials do not have strict control over the construction of cemeteries. It was proven that the metals chromium, barium and copper had high concentrations, indicating soil contamination. He identified the presence of the bacterium Eschirichia coli, from the coliform group that is the causative agent of most urinary infections, kidney. One of the main alternatives to solve or minimize these problems is the vertical cemeteries. Keyword: Cemitery, Necrochorume, Contamination.


The subject I bring before you this evening has so long been connected with my name, and the communications made have been so numerous, that you hardly expect any new developments. This paper is presented, however, from a different angle, in order to explain the reason why investigators and clinicians alike have so long misinterpreted the structure of the enamel as well as the possibility of post-eruptive changes in this tissue. A demonstration of the presence of an organic matrix in human adult enamel will be presented. The past summer brought me the good fortune of spending a month with Dr. J. Leon Williams, at his home in Maine, where I profited greatly by the many hours we spent together. He had always been decidedly incredulous as to the existence of this matrix in adult enamel, but was open to conviction, if I could furnish irrefutable proofs. Previously he had examined my specimens of this structure minutely, even making photomicrographs of it, but still was not entirely convinced of the truth of my assertion. It was his contention that decalcification had not been carried far enough and that the structure I showed in my slides must be brittle and inorganic in nature. He demanded the proof which I will repeat here tonight at the conclusion of this paper. When this proof was furnished, then and not till then was Dr. Williams convinced. It was good to hear his: "That settles it," for it has been a long, long controversy, but one worth ten times the labor spent to win such an ally. He again infused me with enthusiasm concerning the importance of the existence or non-existence of a matrix in the adult enamel. There is no doubt that, as Dr. Williams says, the enamel is the first and strongest barrier against


We have a lot of products designed for use by hand, like a mobile phone, mouse, and camera, etc. These products can be used by many kinds of people whose hands come in various sizes. Designing a handheld product, therefore, it is required to consider the individual difference of user's hands. So there are the high expectations for simulating the interaction between user's hands in various sizes and the product in order to evaluate the product design without prototyping. To achieve it, the technology that generates various Digital Hands automatically from data of hand measurements and finds how a user grasps the product is needed. In this paper, we propose the method that measures 23 lengths and 9 widths included in all fingers automatically from a single image which is got by scanning palm side of a hand using any paper scanner. And we use these resultant measurements for estimating 9 thicknesses and 5 boundary lengths included in fingers or a palm that are perpendicular to the scanned surface. Finally, we try to deform the resultant Digital Hand model into a grasping posture.


The universality of trajectory scaling function (TSF) for the polynomial form of the circle map in the quasiperiodic-to-chaos transition is discussed. It is found that the TSF gets bumpier with increase in the degree of inflection z, for both Golden and Silver Mean cases, and shows multiple scaling with increase in z, reflecting the monotone decrease of α with increasing z. The effect of noise is also studied.


We report thorough experimental characterization of the nucleation and stationary propagation of self-healing slip pulses at a gel/glass interface under constant stress loading. We show that the slip front can be nucleated heterogeneously at the edges of the contact or homogeneously inside it. The resulting slip front can propagate both in the direction of slip or backwards; its velocity depends on the applied stress through a local tip process that is independent of specimen geometry. The backward tip velocity is slower than the front tip velocity by a factor of 4. Both velocities increase linearly with the applied stress jump, with a threshold below which no pulse can form. The pulse length and the total slip is found to be a linear function of the tip velocity. We address the complex problem of selection of the pulse velocity, length and associated slip by using a simplified analytical model. We emphasize the crucial role played by non-linearities of the friction law.


Many patients with Wegener's granulomatosis (WG) have anti‐neutrophil cytoplasmic antibodies (c‐ANCA). Aside from being a diagnostic marker, these autoantibodies may play roles in disease pathogenesis. Proteinase 3 (PR3) is the primary target of c‐ANCA in WG patient sera. Of 60 c‐ANCA‐positive patients, 10 patients were selected for detailed humoral epitope analysis, contingent upon serum availability, using samples with positive levels of anti‐PR3 by enzyme‐linked immunosorbent assay (ELISA). Sequential epitope specificities of anti‐PR3 antibodies detected by screening the maximally overlapping solid‐phase octapeptides of PR3 showed seven major common antigenic targets bound by WG patient sera. These include novel and previously identified sequential PR3 epitopes bound by c‐ANCA. B cell epitope prediction algorithms identified all or part of the seven defined epitopes. Several epitopes share sequence and structural proximity with functional sites, including the catalytic triad and proposed binding sites of other potential proteins [PR3 complementary peptide and soluble endothelial protein C receptor (sEPCR)]. Epitope 4 (VVLGAHNVRTQ) had the highest binding prevalence (90%) and epitope 2 (AQPHSRPYMAS) has the highest average reactivity of the antigenic regions. Epitope 4 includes the interaction site between sEPCR and PR3 which may serve as an important interaction to down‐regulate inflammation. Epitopes 3, 5 and 7 are in direct proximity to amino acids that form the catalytic triad of the protein. c‐ANCA targets both unique and previously known sequential PR3 peptides. This information may prove useful in understanding anti‐PR3‐mediated disease pathogenesis in systemic vasculitides.


Peter Abelard is well known for his place in twelfth-century philosophy and theology. He is also associated with a re-emergence of an emphasis on inwardness in the twelfth century. In the work of Hugh of Saint Victor one also finds a strong emphasis on the 'inner man'. Though for different reasons, both Abelard and Hugh figure in the history of the twelfth-century's turn towards an emphasis on inwardness. This chapter examines how both Abelard and Hugh consider the relation between inner and outer. It shows that for Hugh inner and outer function within a comprehensive worldview in which their correspondence is ultimately dominant, in the world as a whole as in man, whereas for Abelard they articulate an inevitable tension at the heart of the search for a true moral life.

The construction industry has been considered as refractory to information technologies. However, new technological approaches, such as the Building Information Modeling (BIM), are becoming increasingly adopted and are promising better collaboration, better flow optimization and greater integration of the supply chain. These changes are preparing the industry for the advent of "Construction 4.0", a more federating concept than BIM. This article explores the concept and shows how tall wood buildings could show the right path and lead the way for the rest of the industry. The research shows that while tall wood construction actually presents the potential to fit the construction 4.0 requirements, current practices are far from being uniform from one project to another. It also illustrates the need for a close collaboration between practitioners and researchers in order to overcome the current challenges.


BACKGROUND
Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) characterised by chronic pain, swelling and skin changes in the affected limb. One in every three patients with DVT will develop post-thrombotic complications within five years.

OBJECTIVES
To determine the relative effectiveness of, and the rate of complications using non-pharmaceutical interventions in patients with DVT in the prevention of PTS.

SEARCH STRATEGY
The reviewers searched the Cochrane Peripheral Vascular Diseases Group Specialised Trials Register (last searched January 2003), and the Cochrane Central Register of Controlled Trials (CENTRAL) (last searched Issue 4, 2002). In addition, hand searching of non-listed journals and personal communications with researchers was undertaken.

SELECTION CRITERIA
Randomised controlled trials (RCTs) of non-pharmaceutical interventions, such as bandaging and elastic stockings in patients with clinically confirmed DVT. The primary outcome was the occurrence of PTS. There was no restriction on date or language. One reviewer (DNK) identified and assessed titles and abstracts for relevance. This was verified independently by a second reviewer (RS).

DATA COLLECTION AND ANALYSIS
Data extraction was undertaken independently by two reviewers (DNK, RS), using data extraction sheets.

MAIN RESULTS
Three RCTs that evaluated compression therapy were identified. Two studies compared elastic compression stockings with a pressure of 30-40 mm Hg at the ankle with no intervention applied directly after an episode of DVT. The other small study compared elastic compression stockings (pressure 20-30 mm Hg) with stockings that were one to two sizes too large in patients one year after DVT. Overall, in the treatment group at two years, the use of elastic compression stockings was associated with a highly statistically significant reduction in the incidence of PTS with odds ratio (OR) 0.31 (95% confidence interval (CI) 0.20 to 0.48). In addition, the incidence of severe PTS was reduced from OR 0.39 (95% CI 0.20 to 0.76). In another RCT that considered the first nine days post DVT, no difference in the incidence of pulmonary embolism and size of thrombus in the femoral vein was found. A statistically significant reduction (p <0.05) was found in pain, swelling and clinical scores, favouring the compression group.

REVIEWER'S CONCLUSIONS
There is substantial evidence that elastic compression stockings reduce the occurrence of PTS after DVT. No serious adverse effects were mentioned in the studies. Hence, elastic compression stockings should be added to the treatment of DVT to prevent the development of post-thrombotic syndrome.


Eco responsive strategies of green mediate synthesis of nanoparticles are the current analysis within the extremity of nanotechnology. Copper Oxide nanoparticles (CuO Nps) based on Morinda citrifolia leaf extract were synthesized by a biological method and characterized by XRD, SEM, UV-DRS, Zeta potential, and FTIR.

Introduction: The transforming growth factor-beta (TGF-s) cytokine family regulates cellular proliferation, differentiation, and migration with important function during both development and repair. Moreover, the TGF-ss are growth inhibitory for keratinocytes, proliferative for fibroblasts, and generally profibrotic during repair. In order to better define the influence of keratinocyte TGF-s during these processes, we examined the TGF-s isoform, receptor, and signal messenger Smad expression in fetal and postnatal keratinocytes.

Methods: Sprague-Dawley rat keratinocytes were isolated in primary culture from fetal at E15 and E17 (term = E22), newborn, and 6 week old adults. Open fetal rat wounds heal without scar at E17 gestation. Quantitative-polymerase chain reaction was performed for TGF-s1, -s2, and -s3 ligand; TGF-beta receptor1 and -receptor2; Smad3, Smad4, and Smad7 expression. All cells were passage 2 or 3.

Results: TGF-s1 expression did not change appreciably from E15 to adult age in keratinocytes. TGF-s2 and -s3 expression increased (8 fold and 2 fold respectively) from E17 to newborn ages. Overall, the expression of TGF-s1 was 5–8 fold greater compared to -s2 and -s3 in both fetal and adult keratinocytes. TGF-s receptor1 expression increased 2 fold whereas -receptor2 expression showed little change from E17 to adult age. Smad3 expression increased over 50 fold, with Smads 4 and 7 showing a smaller increase from E17 to adult age.

Conclusions: The TGF-beta system has differential expression in fetal compared to postnatal keratinocytes, which suggests function during skin differentiation. TGF-s1 expression is relatively greater than -s2 and -s3 in both fetal and adult keratinocytes. However, increases in isoforms -s2 and -s3, receptor1 and the Smads occurs at ages associated with scarring, implying increased function of the pro-fibrotic TGF-beta response during ages associated with scarring.

This article analyzes the role of domain skill in information seeking by individual human beings. It discusses the form and content of information in long-term memory ("knowledge"). Issues relating to acquisition and retrieval processes are surveyed. Special attention is paid to so-called feature analytic models or frame representations. It is argued that frame-organized knowledge has a constraining function on the availability of alternatives and that frames entail implicit knowledge. Lack of knowledge may have the consequence of either too many or no alternatives in short-term memory during information search

A "frame-system framework" should be used as a conceptual tool for understanding cognitive processes during information seeking and decision making in computerized environments. The suggested framework is illustrated with empirical data from a psychological experiment with a textual data base.


Abstract Background: According to the American Academy of Pediatrics, infants should be exclusively breastfed for the first 6 months of life followed by breastfeeding with complementary food for up to 2 years of age or beyond. Knowledge of breastfeeding recommendations may greatly influence breastfeeding practices; however, the association between a woman's knowledge of exclusive breastfeeding recommendations and breastfeeding duration is not well explored. This study aims to examine the relationship between knowledge of exclusive breastfeeding recommendations before birth and breastfeeding duration. Materials and Methods: Data from the prospective, longitudinal 2005–2007 Infant Feeding and Practices Study II were analyzed (N = 2,935). Knowledge of national breastfeeding recommendations (yes; no) was based on a survey question asking the recommended length of breastfeeding. Breastfeeding duration was reported in weeks and was analyzed as any breastfeeding or exclusive breastfeeding. Cox proportional hazar...

One of key problems of nuclear standard frequency development is preparation assembly of ultracold thorium ions in Pauli trap. In this case semiconductive frequency-stabilized lasers with external resonator on frequencies 690 nm, 984 nm, and 1088 nm are used for excitation of corresponding electronic dipole and quadrupole cooling transitions for Th3+ ions. In the paper the results of development and creation of unified laser module, which is able to be used as base for full-featured system designed for laser cooling of Th3+ ions, are presented. The module is able to fine-tune necessary wavelength with accuracy ±5 nm.


With the help of recent adjacent dyadic constructions by Hyt\"onen and the author, we give a simple alternative proof of results of Lechner and Passenbrunner about the $L^p$-boundedness of shift operators acting on functions $f \in L^p(X;E)$ where $1 < p < \infty$, $X$ is a metric space and $E$ is a UMD space.


Micro-rotor pivot is a main component of rotation micro-machinery in power MEMS(micro-electro-mechanical system) and can be worn at the operation of the system. Statistics method and fractal method have been applied to analysis the effect of micro-scaling on the wear. A hemispherical pivot model is presented, the dimensional and volumetric wear rates and friction torque are investigated, and the effects of geometry parameters and operation parameters on the wear characteristics are discussed in detail. It is indicated that the wear coefficient decreases with the decrease of the scaling and the wear becomes serious with the increase of the applied loading or the rotation numbers.


Fly ash from a South African power station ash dam was used. The fly ash approximated Class F fly ash but had a loss on ignition greater than 6%. The leaching parameters investigated were leaching time, KOH concentration, agitation speed, fly ash particle size, leaching temperature and liquid solid ratio (L/S). It was found that the optimum leaching conditions were leaching time of 6 h, 3M KOH, 500 rpm agitation speed, 25 L/S ratio, leaching temperature of 100 C. Silica leaching followed a modified Jander equation kinetics with an N value of 1.48 and an activation energy of 5.9 kJ/mol. Key-Words: Fly ash, Leaching, Potassium silicate,


The parameters of the boson peak (BP) and the first sharp diffraction peak (FSDP) in (As2S3)x(GeS2)1x glasses measured using high-resolution Raman spectroscopy and high-energy synchrotron X-ray diffraction measurements are examined as a function of x. It has been found that there is no correlation between the positions of BP and FSDP. The BP position shows a nonlinear composition behavior with a maximum at about x = 0.4, whereas the FSDP position changes virtually linearly with x. The intensities of both BP and FSDP show nonlinear composition dependences with the slope changes at x = 0.4, although there is no direct proportionality. Analysis of the partial structure factors for the glasses with x = 0.2, 0.4 and 0.6 obtained in another study has shown that the cation-cation atomic pairs of Ge–Ge, Ge–As and As–As make the largest contribution to FSDP, where the Ge–Ge and Ge–As pairs are dominant.


606 Background: Topoisomerase I (topo-I) degradation by ubiquitin proteasomal pathway (UPP), in response to camptothecins (CPTs) is linked to the CPT response. But the mechanism is not understood. Methods: Improvised GST pull down experiments were performed to isolate topo-I interacting proteins which were analyzed by SDS-PAGE and identified by mass spectrometry. DNA-PKcs mediated phosphorylation of GST-topo-I was analyzed by SDS-PAGE and autoradiography. Immunoblot analysis of anti-BRCA1 precipitates from HCT15 cell lines was performed. GST-topo-I phosphorylated by DNA-PKcs, was incubated with the BRCA1/BARD1 heterodimer in the presence of E1, UbCH5c and ATP in ubiquitination buffer. Four triple negative breast cancer cell lines were selected to compare the degree of topo-I degradation. Colorectal cancer (CRC) tissues were immunostained with 1C1.H5.H7 to determine topo-I-pS10 level and identify a correlation between the topo-I-pS10 level and CPT response. Results: We isolated a topo-I interacting protein...

: Online education is one of the fastest emerging markets globally. There is a variety of tools, technologies and platforms, which augment learning in the online environments. Moodle and Sakai are probably the most popular open-source learning management systems (LMS) around the world, although there are alternative professional solutions such as TalentLMS or other platforms. Student interaction is one of the success factors of effective online teaching and learning. It is important to understand how students behave in an online environment. This provides good feedback to the syllabus developers and instructors, in order to examine what should be improved. The learning management systems provide a good way for analyzing learners' behavior through log reports. The LMS records all kinds of interactions by all users. These data are processed using learning analytics, in order to obtain a good picture of the progress achieved by the students during the lectures and the laboratories and of the manner in which the professors manage the students' learning curves. This paper explains the use of learning analytics in examining learners' engagement, interaction and behavior in an online environment. The results revealed interesting findings on how the assessment should be organized, in order to find maximum learning attainment.
