Within this work, the conventional PD-controller is proposed to suppress the lateral oscillations of a nonlinear Jeffcott-rotor system. Time-delays in the control loop are included in the system model. The slow-flow modulating equations governing the whole system dynamics are obtained. Influence of the controller gains and time-delays on response curves are explored. The analyses showed that the controller efficiency has been enhanced at specific values of time-delays; while the system may lose its stability at the other values. The phenomenon of enhancing the controller efficiency was explained and accordingly the optimal values of the loopdelays have been reported.


Various notions of stable ranks are studied for topological algebras. Some partial answers to R.G. Swan's problem (Have two Banach or good Fréchet algebras as in the density theorem in K-theory the same stable rank ?) are obtained. For example, a Fréchet dense ∗-subalgebra A of a C∗algebra B, closed under C-functional calculus of self-adjoint elements, has the same Bass stable rank as B.


ABSTRACT Dialogue on war is difficult and uncomfortable, for both political and personal reasons. In this article, Maya Eichler, a feminist scholar of militaries and military conflict, and Jessica L. Wiebe, a female veteran artist, describe their experiences of co-writing and co-performing "The Weight We Share." Drawing inspiration from Sarah Bulmer and David Jackson's piece "You do not live in my skin", they share these reflections on their collaborative work to illustrate how art has helped them to sit with the discomfort of engaging in conversations that challenge deeply-held beliefs and emotions about the military and war.


This paper proposes to replace the Intraframes of MPEG- 2 with JPEG2k coded bitstreams governed by the syntax of MPEG-2 spatial scalability. The paper elaborates upon the proposed coding architectures and compatibility with published MPEG standards. The proposed coding architecture is compared against counterpart video transcoders, scalable and single layer codecs. It is shown that the proposed spatial encoder is either comparable or superior to all the aforementioned codecs whilst enjoying an extensible architecture capable of serving restricted end systems and hosting additional scalable layers such as SNR and temporal scalabilities.


The problem is to describe, analyze, and evaluate three approaches to the teaching of reading in grades one through six in selected school districts in a California county. The three approaches are 1) the Basic Reading Approach, 2) the Individualized Reading Approach, and 3) the Language Experience Approach to reading.


ABSTRACT This essay proceeds in three parts. The first part introduces a Māori waiata (a ceremonial song, with movements) that occurred in the debating chamber of the New Zealand parliament in 2017 on the Third Reading of Te Awa Tupua (Whanganui River Claims Settlement) Bill. The resulting statute confers legal personality on the Whanganui River. The second part advances a way of approaching musical appreciation as a mental activity which, by joining sound to musical meaning not only makes musical sense of sound, but can also, in so doing, be said to participate in the process of making music. Crucial to the move from making sense of music to making music, is the notion that music is inherently a metaphorical way of thinking about sound; one in which the music metaphor operates by making sound humanly meaningful. The third part – proceeding from the idea that music operates as metaphor and, like all metaphor, produces meaning by translating abstractions into concrete conceptions – posits music as a bridge (a joint or articulation) between eras, cultures and social strata that might otherwise struggle to find meaningful points of connection and communication. The hope is that we might come to understand law making music in the sense both of 'law making' music and law 'making music'.

Objective To explore the methods and efficacy of high risk patients with large volume benign prostatic hyper plasia surgery.Methods One hundred and eight cases of high risk patients with large volume benign prostatic hyperplasia were randomly divided into observation group and control group,each of 54 cases,the observation group was treated by the prostatic urethra and plasma bipolar electrosurgical excision procedure(TKRP) treatment while the control group received or dinary transurethral resection,the clinical efficacy and adverse reactions were compared.Results Operation of two groups were successful.The operative time,intraoperative blood loss and postoperative complications of observation group were less than those of the control group,the removal of the gland weight of observation group was higher than that in the con trol group,there were significant differences(P 0.05);Qmax and RUV,IPSS and QOL indicators in both two groups were improved significantly compared with those before treatment,there was significant difference(P 0.05),but there was no significant difference between the two groups(P 0.05).Conclusion TKRP is a surgery with short surgery time,less bleeding and fewer complications,is the preferred treatment in high risk patients with large volume benign prostatic hyperplasia.


Lack of synchronization between high voltage DC systems linking offshore wind farms and the onshore grid is a natural consequence owing to the stochastic nature of wind energy. The poor synchronization results in increased system disturbances, grid contingencies, power loss, and frequency instability. Emphasizing frequency stability analysis, this research investigates a dynamic coordination control technique for a Double Fed Induction Generator (DFIG) consisting of OWFs integrated with a hybrid multi-terminal HVDC (MTDC) system. Line commutated converters (LCC) and voltage source converters (VSC) are used in the suggested control method in order to ensure frequency stability. The adaptive neuro-fuzzy inference approach is used to accurately predict wind speed in order to further improve frequency stability. The proposed HVDC system can integrate multiple distributed OWFs with the onshore grid system, and the control strategy is designed based on this concept. In order to ensure the transient stability of the HVDC system, the DFIG-based OWF is regulated by a rotor side controller (RSC) and a grid side controller (GSC) at the grid side using a STATCOM. The devised HVDC (MTDC) is simulated in MATLAB/SIMULINK, and the performance is evaluated in terms of different parameters, such as frequency, wind power, rotor and stator side current, torque, speed, and power. Experimental results are compared to a conventional optimal power flow (OPF) model to validate the performance.


The physical properties of radiation- and sulfur-cured poly(butadiene-co-styrene)-based stocks were compared. It was found that the measured lower ultimate strength of radiation-cured stocks is in part attributable to the difference in the glass transition temperatures of the stocks cured by the two methods (an increase in T/sub g/ is caused by sulfur curing). Another factor contributing to the difference in performance is the apparent nonuniform crosslink density distribution in radiation-cured stocks containing carbon black filler. A higher crosslink density in the immediate vacinity of carbon black particles was postulated based on a to-be-expected distribution of secondary electron energy at interfaces with an appreciable change in density between neighboring phases. The invoked difference in network topology, supported by solvent swelling measurements on sulfur- and radiation-crosslinked vulcanizates can explain not only the slightly lower ultimate strength of radiation-cured stocks but also the superior fatigue and crack propagation performance measured for these vulcanizates. Finally, theoretical arguments were presented to explain the inferred large strength deficiency of radiation-cured rubbers reported by other investigators on the basis of chain scissions encountered during radiation crosslinking.

24 © 2008 Isaiah T. Awidi Successful technologies for higher education provide integrated software applications that support both instructors and students. As educational delivery has shifted from traditional face-to-face to more blended learning and to online learning, student enrollment in developed countries has increased. At higher education institutions in Ghana, however, the limited infrastructure has not been fully integrated to support collaboration, assessment, feedback, student learning, and lecture preparation and presentation. These weaknesses in the infrastructure have hampered support of students both on campus and through alternative modes of instruction. Course management systems (CMSs) currently drive educational delivery in most developed countries. Their absence in higher education in most developing countries creates a digital divide between firstand third-world students. Meeting the needs of higher education in Ghana therefore depends on identifying the factors that should inform the choice of such a system. To determine the factors crucial to choosing a CMS for Ghanaian higher eduClose consideration of key issues involved in choosing a CMS helps universities avoid the typical barriers to successful implementation and adoption


When a student comment in class intimated possible intolerance, a teacher in Georgia revamped her endof-year unit to include mini– critical discourse analyses.


A macroscopic Traffic Simulation and Optimization (TSAO) model has been developed for regional highway networks. It was applied to the Maryland Eastern Shore network, where heavy recreational traffic creates severe congestion and long queues at bottlenecks on summer weekends. Fourteen alternatives for improvement, including capacity expansion projects and route diversion, were analyzed. Results show the cost-effectiveness of route diversion as a substitute for new construction on intercity networks where high demand peaks are infrequent. The applicability of the TSAO model to large networks with complex demand patterns and insufficient capacity is also demonstrated.


This experimental study investigated in to the flow characteristics around staggered cooling tube arrays of fan coil unit for ship. A particle image velocimetry technique was employed to obtain detailed measurements at inlet-velocity-based Reynolds numbers of . As for the results, the flow evolves rapidly and becomes spatially periodic in the streamwise direction after a relatively short distance. The flow exhibits strong Reynolds number dependence in developing region but no significant Reynolds number effects are observed in spatially periodic region


OBJECTIVE:
To report clinical and radiologic features of intracranial arterial dissections (IAD).
 BACKGROUND:
The absence of external elastic lamina with a thin muscular layer and adventitia predispose to IAD. The frequency and pattern of IAD is unknown in Argentina. We report a single institution series of IAD from Buenos Aires, Argentina.
 DESIGN/METHODS:
Data was retrospectively obtained from the FLENI Stroke Data Bank between 1994 and 2013. We assessed demographic characteristics, clinical presentation, diagnostic tests, acute treatment, and outcome at six months.
 RESULTS:
Of 297 patients with cerebral arterial dissections (CAD), 117 (39%) were extracranial artery dissections (EAD), 97 (33%) were EAD/ IAD, and 83 (28%) were IAD. Mean age for IAD was 44±12 years, and 63% were men. Clinical presentation was: ischemic stroke (71%), pain/Horner/tinnitus (21%), transient ischemic attack (4%), and hemorrhagic stroke (4%).
Diagnosis was made by MRI, angio-TC, ultrasound and/or digital subtraction angiography. The most frequent patterns were: stenosis (71%), occlusion (13%), dissection flap (7%), and dissecting aneurysm (8%). Patients were treated with antiaggregants (50%), anticoagulants (46%), r-TPA (2%), surgery (1%) or no treatment (1%).
At six-months follow up, 63% of the patients had a mRS 0/1, 32% of 2/3, and 4% of 4/5. One patient died during follow up (1%)
 CONCLUSIONS:
IAD represent a substantial proportion of CAD and may be a frequently underdiagnosed cause of stroke. Intraparenchymal hemorrhage seemed to occur less frequently in our series than previously reported.

This paper introduces a control technique for proportional load sharing in a DC microgrid during both islanded and utility connected modes. The DC microgrid is connected to a utility system through an interlinking voltage source converter and a unidirectional DC-DC converter. The DC-DC converter draws the desired amount of power from the utility, while the interlinking converter holds the DC bus voltage. The DERs in the DC microgrid are operated under droop sharing using DC-DC converters. Each DC-DC converter is equipped with a state feedback with integral controller that can regulate its output voltage for a wide range of input voltage fluctuation and load variation. Simulation studies are conducted on PSCAD/EMTDC to validate the proposal.


Essential oils are most frequently used in a variety of cosmetics, food and medicinal preparations. E. oil of Teucrium polium possesses profound antinociceptive potential. The current study aimed to explore the antimicrobial and cytotoxic potentials of the E.oil of Teucrium stocksianum. E. oil exhibited profound antibacterial potential against both Gram positive and Gram negative bacterial strains. Pseudomonas aeruginosa has shown marked (MIC, 250 μg/ml) susceptibility to the constituents of the E. oil followed by Bacillus cereus and Escherichia coli (MIC, 450 μg/ml each). In the cytotoxic assay the test sample indicated moderate lethality (LC , 1200 μg/ml) against brine shrimp's nauplii. Maximum activity (62%) was observed at 50


Novel hybrid binder concrete mixes with alkali-activated non-ferrous slag (NFS), either alone or in combination with blast furnace slag (BFS), as partial replacement of Portland cement, and containing 50% recycled aggregates, were successfully manufactured. The compressive strength, carbonation resistance, chloride resistance, frost scaling, sorptivity coefficient, and water penetration resistance were thoroughly assessed. The presence of recycled aggregates had an adverse effect on early-age strength, but after 91 days there was no difference between concrete with and without recycled aggregates. The chloride-binding capacity was enhanced in the BFS/NFS system with recycled aggregates (reduction in chloride ingress coefficients of ~28–35% compared to recycled concrete with NFS only). This is most likely caused by the binding of Cl ions in calcium alumina silicate hydrates (C-A-S-H) and ettringite phases. However, when compared to the system with virgin aggregates, BFS/NFS concrete with recycled aggregates showed increased carbonation rate (+30%) and frost scaling (+15%). Durability properties, such as sorptivity and water penetration resistance, were positively affected by the curing time for the BFS/NFS system (~35–45% further improvement from 28 to 90 days with respect to the NFS system). Specimens that were wet cured for 91 days showed improved results compared to the 28-day cured samples due to the slow pozzolanic reaction of the NFS.


This work is an attempt at converting waste products from food, peels of Musa sapientum into useful pharmaceutical excipient. The gum from the peels was extracted, dried and pulverized by an already established method.  A similar process was carried out with M. acuminata peels.  Interaction studies were carried out using differential scanning calorimetry (DSC).  Paracetamol granules were prepared with mucilage of the gums extracted from the peels at concentrations of 2, 4, 6, 8, and 10% w / w of tablet weight using the mucilage and employing the wet granulation approach.  Similar batches of paracetamol granules were prepared using sodium carboxymethyl cellulose (SCMC).  The flow and compressibility properties of the granules were evaluated.  The granules were compressed into tablets and evaluated for hardness, friability, disintegration and dissolution.  The DSC results reveal that the gum is compatible with paracetamol.  Also the gum compared favorably with that of M. acuminata and also SCMC in terms of compact characteristics, such as hardness [ M. sapientum - 2% (6.55±0.86); 4% (6.00±0.53); 6% (5.60±0.39); 8% (5.50±0.67); 10% (5.35±0.46): M. acuminata- 2% (4.60±0.74); 4% (5.65±0.53); 6% (5.50±0.33); 8% (6.00±0.41); 10% (6.45±1.07): SCMC – 2% (6.55±0.28); 4% (9.23±1.20); 6% (11.65±2.74); 8% (13.39±2.13); 10% (6.20±2.45)], disintegration [ M. sapientum – 2% (11±1.7sec); 4% (10±0.9 sec); 6% (15±1.4 sec); 8% (12±1.4 sec); 10 (11±1.4 sec): M. acuminata – 2% (19±1.4 sec); 4% (17±1.3 sec); 6% (12±1.0 sec); 8% (13±0.9 sec); 10% (18±0.9 sec): SCMC – 2%, 4%, 6%, 8% and 10% > 15mins].  Drug release from the tablets formulated with the M. sapientum gum was rapid, reaching 100% within 30 minutes.  This is similar to the release profile of tablets formulated with M. acuminata, whereas tablets formulated with SCMC had much longer release times. Friability values were higher with M. sapientum gum – 2% (14.56%); 4% (23.73%); 6% (15.03%); 8% (14.18%); 10% (14.57%): M. acuminata – 2% (11.76%); 4% (8.08%); 6% (10.58%); 8% (3.29%); 10% (0.18%): SCMC – 2% (1.61%); 4% (0.21%); 6% (0.11%); 8% (0.09%); 10% (0.28%), thus admixtures with SCMC might be a good option.  The gum from M. sapientum gave a yield of 65% ( w / w ) which was high and the starting material is readily available.  Thus, it could be an alternative source of adhesives suitable to be employed for the manufacture of immediate release paracetamol tablets.

The pollination biology and breeding system of Pseudobombax munguba, a tree species of the várzea of the Amazonian floodplain, was studied by field observations and hand pollinations using varying proportions of self and cross pollen. Progeny in sample fruits were tested for self or cross paternity using an isozyme genetic marker. Pseudobombax munguba has nocturnal, white, brushlike flowers that, surprisingly, lack nectar, and they are pollinated by a single, large bat species, Phyllostomus hastatus. Although self pollen tubes penetrated ovules with equal facility to cross tubes, fully selfed flowers failed to form fruits. Flowers with mixed (

Fruits from such mixed pollinations contained varying but generally low (mean 3.3%, range 0%–22%) numbers of selfed seed. We conclude that although P. munguba lacks a conventional stigmatic or stylar self‐incompatibility mechanism, the combination of exclusive pollination by a wide‐ranging bat vector and the death of most selfed ovules provide this species with a highly outcrossing mating system.


The revised baseline mission concept of the Space Infrared Telescope Facility (SIRTF) has assumed that the infrared array camera (IRAC), one of three focal plane instruments designed for SIRTF, will be removed from SIRTF and carried out collaboratively on the Japanese- launched Infrared Imaging Surveyor (IRIS) mission. The IRIS mission is an approved program scheduled for launch in 2001. In addition to IRAC, which will cover the 3 - 8 micron wavelength region, the proposed IRIS mission will also contain a mid-infrared array camera and a far-infrared scanner, consisting of three linear array detectors. We review the scientific requirements and design of IRAC required for incorporation into IRIS.


Although most states have laws that explicitly allow physicians to refuse to provide certain medical services, the policies pertaining to pharmacists are less clear. The purpose of this report is to determine which states have laws or regulations that address a pharmacist's right to refuse to dispense prescriptions based on moral grounds. Fifty Boards of Pharmacy were contacted via phone or E-mail regarding regulations as well as active or pending legislation. Information was also solicited from various state Governors' legislative offices and Web sites. Typically, individual state practice codes allow pharmacists to refuse to fill a prescription if in their professional judgment the prescription is outside the scope of practice of the prescriber; if the validity of the prescription is in question; or to protect the health and welfare of the patient. Only five states have a "conscience clause" that allows a pharmacist to refuse to fill or refill certain prescriptions, which he or she finds morally objectionable: Arkansas (contraceptives only), California, Georgia, Mississippi, and South Dakota (abortifacients and assisted suicide only). In contrast, Illinois, Massachusetts, North Carolina, and Pennsylvania have an emergency rule or regulation, which states or implies that all legal prescriptions must be dispensed or transferred. Seventeen states considered proposed bills during their respective 2005 legislative session The rights of pharmacists to refuse to dispense certain prescriptions vary widely from state to state. The protection provided to an individual pharmacist may be very broad or very specific depending on the wording of the statute or regulation.

Widespread declines in insects will threaten ecosystem functioning and services. Nevertheless, a lack of data hinders assessments of population and biodiversity trends for many insect groups and thus effective conservation actions. Implementing cost‐effective, unbiased, and accurate monitoring programmes targeting different groups across a larger geographical range has therefore become a key conservation priority. We evaluated a sampling protocol designed for community science initiatives targeting butterflies and bees. Specifically, we tested how well a short (200‐m long) version of traditional Pollard walk transects, designed to be accessible for large numbers of community scientists, captures changes in alpha and beta diversity of these two pollinator groups. We used resampling methods to simulate and assess scenarios varying in sampling intensity and frequency. We found that alpha and beta diversity of butterflies and bees were estimated at similar accuracies across different scenarios, which suggests that even short transects can provide useful information on diversity patterns for both taxa. However, common sampling frequencies resulted in low accuracies (e.g. one sample every 10 days finds on average ~50% of the species present at a site). We discuss our results in the context of developing large scale, structured monitoring systems for multiple insect taxa, and how information on biodiversity patterns can inform the expansion of monitoring schemes. We explain why, moving forward, even rapid sampling designs similar to the approach tested here will be useful given a higher potential to involve community scientists, data integration techniques, and the opportunities to sample under‐represented habitat types


In the November/December issue of Headache, we reported a case of external hydrocephalus due to intracranial hypertension from a cryptococcal meningitis. His presenting headache at that time of onset was located occipitally with photophobia and increased in severity in supine position. The same patient returned to the emergency room 17 months later with a slightly different clinical presentation. Two weeks prior to this presentation, the patient developed headaches located at the vertex, aggravated by sitting and standing positions and relieved with supine position. There was no associated neck stiffness, blurring of vision, photophobia, nausea, vomiting, or gait imbalance. After being diagnosed with HIV/AIDS, the patient was placed on antiretroviral therapy and fluconazole but was not compliant with his medications. One week prior to onset of symptoms, the patient had an influenza vaccine with subsequent fever, chills, and fatigue lasting 2 days. Neurologic exam revealed bilateral papilledema and a mildly wide-based gait but no nuchal rigidity or weakness as noted on prior visit. The patient was already sent to the emergency room with a magnetic resonance imaging (MRI) of the brain by his primary medical doctor that showed a moderate communicating hydrocephalus which can be seen when compared with prior MRI (Fig. 1). Figure 2 shows widening of the temporal horns of the lateral ventricles, another sign of hydrocephalus. (Though not shown here, the fourth ventricle was enlarged as well.) Interestingly, there was not much change in the external hydrocephalus (Fig. 3). The patient had an opening pressure of 46 cm H2O on lumbar puncture with 118 ¥ 10 white blood cells (92% lymphocytes), a total protein of 142.3 mg/dL (normal 15-45 mg/dL) and a cerebrospinal fluid (CSF) glucose of 9 mg/dL (serum 85 mg/dL). Though India ink staining was negative, the cryptococcal antigen was positive at 1:1024. The patient was treated and sent home. The lumbar puncture relieved 60% of his headache symptoms. When a patient complains of headaches that are aggravated on elevation of the head and relieved on supination, physicians tend to think of intracranial hypotension as the etiology. This patient, however, presented with a positional headache characteristic of intracranial hypotension and an unexpected hydrocephalus with an increased cerebrospinal fluid pressure. The pathophysiology behind these clinical symptoms is unclear.While there was an interval increase in the size of the lateral ventricles, this is a probable new finding in this patient as his original meningeal infection was treated satisfactorily. Low-pressure headaches have been reported following removal of cerebrospinal fluid to relieve intracranial hypertension, but this clinical scenario


Abstract In this paper, high-pressure data from a synchrotron X‑ray diffraction study on a lillianite (Pb3Bi2S6) single crystal up to ~21 GPa are presented. A phase transition from lillianite (space group Bbmm, LP lillianite) to the high-pressure form β-Pb3Bi2S6 (space group Pbnm, HP lillianite) was confirmed and bracketed between 4.90 and 4.92 GPa. The transition is reversible but of first-order with a hysteresis of ~2.8 GPa. It showed weak effects of pseudo-merohedral twinning that disappeared upon decompression, testifying to a full recovery of the single crystal of lillianite. This makes lillianite an interesting shape-memory material. With a bulk modulus K4.9 = 78(3) GPa and K′ = 5.1(4), β-Pb3Bi2S6 is markedly less compressible than lillianite [K0 = 44(2) GPa, K′ = 7(1)]. Compressional anisotropy increases markedly in β-Pb3Bi2S6 with compressibility along the b axis [M0b = 130(6) GPa and Mb′=19(3) $M_{b}^{\prime }=19(3)$in lillianite, M4.9b = 145(4) GPa ′and Mb′=16.0(7) $M_{b}^{\prime }=16.0(7)$in β-Pb3Bi2S6] significantly larger than that along the other two axes [M0a = 118′(5) GPa, Ma′=21(3), $M_{a}^{\prime }=21(3),$M0c = 139(12) GPa, and Mc′=31(10) $M_{c}^{\prime }=31(10)$in lillianite, M4.9a = 242(12) GPa, Ma′=8(1) $M_{a}^{\prime}=8(1)$, M4.9c = 242(5) GPa, and Mc′=29(1) $M_{c}^{\prime }=29(1)$in β-Pb3Bi2S6]. The behavior of lillianite at high pressure is an interesting case study in relation to non-quenchable ultrahigh-pressure phases likely occurring in the inner Earth, like post-perovskite MgSiO3, the oxide homologue N = 1 of the lillianite series. The β-Pb3Bi2S6 structure, on the other hand, is the N = 3 homologue of the meneghinite series to which the higher-pressure modification of the post-perovskite structure also belongs (homologue N = 1). This makes the two forms of Pb3Bi2S6 potential equivalents of high- and ultrahigh-pressure Mg silicates that could occur both in the deep earth and in other rocky extrasolar planetary bodies.

A 1-bit low-profile patch antenna array integrating beam scanning and adaptive high-intensity radiation fields (HIRF) protection is proposed in this paper. Each antenna element consists of two dielectric layers, two radiation patches, a ground plane, and a feeding network. By electronically controlling a pair of coding diodes in the same direction, the antenna element can achieve 180<inline-formula><tex-math notation="LaTeX">$^\circ$</tex-math></inline-formula> phase difference, producing two logical states, namely "0" and "1". It has good beam scanning capability in the range of −60<inline-formula><tex-math notation="LaTeX">$^\circ$</tex-math></inline-formula> to 60<inline-formula><tex-math notation="LaTeX">$^\circ$</tex-math></inline-formula>. When the proposed antenna is exposed to HIRF, the protective diodes mounted over the grounded coplanar waveguide (GCPW) transmission line are triggered, dramatically reducing the overall gain of the antenna array. By optimizing design, the element possesses a bandwidth of 8.8<inline-formula><tex-math notation="LaTeX">$\sim$</tex-math></inline-formula>9.3 GHz. The grating lobe of the antenna array is suppressed by 17.5 dB thanks to the adoption of the non-uniform feed. The simulation results indicate that the proposed antenna element and array have a high isolation degree of 22.4 dB and 23.2 dB when exposed to HIRF, respectively. Finally, a prototype of the antenna is fabricated, and the validity of the proposed design is experimentally verified. The experimental results are in good agreement with the simulation results, demonstrating the validity of the proposed design.

Abstract Olive oil was selected as the oil substrate and hydrolyzed by Candida sp. 99–125 lipase. The hydrolysis rate of olive oil was used as an indicator. Based on the single factor experiment, the effects of dosage of Candida sp. 99–125 lipase, reacting temperature, pH value and water-oil ratio were investigated. Box-Behnken center combination and response surface methodology were utilized to optimize the hydrolysis rate. The results showed that the significant differences of each single factor on lipase hydrolysis of olive oil on the oil-water interface were different. pH value is the first significance factor, and the significance of water oil ratio on lipase hydrolysis of olive oil is second only to pH value. Finally, the mechanism of Candida sp. 99–125 lipase hydrolyzing olive oil at the oil-water interface was discussed.


Groundnut (Arachis hypogaea L.), a self-pollinated legume is an important source of oil and protein. Abiotic and biotic stresses interludes in groundnut production environments. High temperature stress is one of the least well understood and is one of the major uncontrollable factors affecting plant growth, development and productivity. Recognizing the constraints imposed by high temperature to crop adaptation and productivity the present study was planned to screen groundnut genotypes tolerant to heat stress. The experiment was laid out in Alpha-lattice design in two replications. 63 genotypes were evaluated under four different environments viz., E1 (25th Jan'13), E2 (6th Feb'13), E3 (18th Feb'13) and E4 (2nd Mar'13) for the conduct of the experiment. Significant differences for genotypes were found for all the traits under study. Higher magnitude of genotypic and phenotypic coefficient of variation was reported for pod yield, kernel yield, oil yield and haulm weight. High heritability along with high genetic advance as percent of mean was was exhibited by pod yield, kernel yield, hundred kernel weight oil yield, haulm weight, harvest index, pod growth rate, crop growth rate and partioning factor across the four environments. Pod yield was positively and significantly associated with days to maturity, kernel yield, oil yield, oil content, hundred kernel weight, harvest index, haulm weight, crop growth rate, pod growth rate and partitioning factor. Genotype x environment interactions were significant for six traits among which days to 75% flowering, days to maturity and sound mature kernel percentage were highly influenced by heat stress. Based on the mean pod yield for each environment, seven genotypes were identified as top yielders. ICGV 06420 was most stable across the stressed and non-stressed environments. STI was considered more reliable parameter for screening of heat tolerant groundnut genotypes under both stress and non-stress environment. Six genotypes (ICGV 07246, ICGV 07012, ICGV 06039, ICGV 06040, ICGV 03042 and ICGV 06424) were identified as heat tolerant based on STI.


Brugada syndrome (BrS) is an important cause of sudden cardiac death (SCD) with well‐defined ST‐segment elevation patterns on V1–V3. Observation of BrS‐Type‐electrocardiogram (ECG) patterns in medical conditions without true BrS is called "Brugada Phenocopy" (BrP). We present a case of 61‐year‐old male patient with hyperkalemia, hyponatremia, and BrS‐Type‐1 ECG pattern in the setting of acute postrenal failure. He was denying any syncope or family history of SCD. With normalization of electrolyte levels, BrS‐Type‐1‐ECG resolved. Electrolyte disturbances are one of the most common reasons of BrP. Being aware of BrPs and differentiating from an unmasked BrS‐ECG pattern could prevent patients from lethal consequences and unnecessary treatments.


BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) are a kind of multifunctional mesenchymal stem cells that have multi‐directional differentiation potential. These cells can be genetically modified by methods such as adenovirus transfection, to produce a variety of growth factors such as neurotrophin‐3 (NT‐3), angiopoietin‐1 (Ang‐1), and vascular endothelial growth factor (VEGF). BMSCs have been applied as seed cells in tissue engineering research. OBJECTIVE: To transfect VEGF165, NT‐3 and Ang‐1 gene into rat BMSCs and to induce them to differentiate into neuronal cells and vascular endothelial cells. METHODS: BMSCs were isolated using differentia velocity adherent method and identified by flow cytometry. Differentiation potential of BMSCs into osteogenesis and adipogenesis was also identified. We constructed two adenoviral vectors with cytomegalovirus (CMV) as a promoter. One of the two vectors was a bicistronic vector (Adv‐Bic), carrying hVEGF165 and Ang‐1 gene; the other vector was an AdvNT‐3 vector, carrying NT‐3 gene. Adv‐Bic (green fluorescence) and AdvNT‐3 (red fluorescence) were simultaneously transferred into rat BMSCs at various multiplicities of infection (MOIs). Two days after the transfection, the optimal MOI value was determined based on the expression of green and red fluorescent proteins under a fluorescence microscope. Then, well‐grown BMSCs at passage 3 were divided into two groups. The experimental group was transfected with Adv‐Bic (without fluorescence) and AdvNT‐3 (without fluorescence) at the optimal MOI. The control group was transfected with blank control virus at the same MOI. The two groups were cultured in vitro for 7 days and then were detected with immunofluorescence and qPCR. RESULTS AND CONCLUSION: The expression of CD29 and CD44, which are identifications of BMSCs, was positive, while the expression of CD34 and CD45, which are identifications of hematopoietic stem cells, was negative. BMSCs could be differentiated into osteoblasts and adipocytes. After BMSCs were transfected with adenovirus for 48 hours, the expression of green and red fluorescent proteins was observed under a fluorescence microscope. With the increase of MOIs, the intensity of fluorescence gradually increased, and peaked when MOI was equal to 100. Immunofluorescence and qPCR results showed that the expression of VEGF165, NT‐3 and Ang‐1 in the experimental group was higher than that in the control group. The expression level of CD31 and CD34, the markers of vascular endothelium, in the experimental group was higher than that in the control group. The expression level of neuron‐specific markers NSE and Nestin in the experimental group was higher than that in the control group. These results suggested that VEGF165, NT‐3 and Ang‐1 genes were successfully transfected into BMSCs. This transfection made BMSCs overexpress growth factors of VEGF165, NT‐3 and Ang‐1, which could induce BMSCs to differentiate into neuronal cells and vascular endothelial cells.


Movable bracket as an important part of dual-axis tracking solar thermal power system is large, movable and complex of its force with the orbit of connected nodes. At the same time, the system has strict requirements on removable bracket's deformation. The technical feasibility and the cost lever of the bracket structure play decisive roles in the promotion of the application of this new type of solar thermal power system. This paper clarifies the applications operation of solar power system on the basis of the principle of the performance of the support structure for the system requirements, summarizes the mechanical characteristics of the bracket structure, combined with the analysis of the pilot project support structure selection, expounds the key points of structural selection, and determines a more reasonable form of the support structure.


During their schooling, students must go through multiple literacy processes due to the fact that each discipline has special ways to build and communicate knowledge (New London Group, 2000). However, this becomes more difficult, as the meaning and form of terms used in this education may vary with each teacher, depending on the discipline they teach (Unsworth, 2001). From this perspective, the objective of this study (Fondecyt 1130684 Project) is to identify the means and semiotic modes within the teaching of Geography classes, and to recognize their potential through epistemic tools of visual grammar. This work is based on two case studies and the corpus is constituted by the audiovisual records, which allowed the creation of a multimodal inventory of means and ways to communicate (Kress, 2010), that were used by two teachers when teaching geography at primary and secondary level in public schools in Chile. The results show that teachers instruct literacy through various means and modes, which are mostly visual, some of them more complex to understand because of density and number of symbols needed to understand them. From this, it can be seen that within Geography the meanings must be learned and mediated in a multimodal way.


There has been an increasing concern that the global shutdown period during the spread of the COVID-19 epidemic will widen the gender gap, and that the gains of women before the epidemic will decline. Since COVID-19 crisis affects men and women in different ways, measures to solve it must take into account the gender. This study clarifies the student community's interest and awareness of gender equality issues during the initial lockdown period by selecting a representative sample of the student community at Ajman University,362 students out of a 6,042 students, the total number of students, according to Yamani mathematical equation n = N / (1 + Ne


Negotiation automation deals with business processes that frequently require the input of human knowledge to achieve their goal – that of agreement in negotiations. However, traditional business-to-business (B2B) vocabularies on the Web are limited to data exchange, and do not extend to the sharing and production of knowledge. In this paper, we explore the future of the Web: the semantic Web. This study investigates the Electronic Business using Extensible Markup Language (ebXML) platform and introduces a rule base by which negotiation parties can dynamically communicate the logic of their negotiation strategies through the definition of semantic Web rules. Using standardized semantic Web technologies for all of the negotiation parties, we present the application of negotiation automation to agendas and explanations. In particular, explanations take advantage of the technology that allows rules (or human logic) to operate in remote systems and to interface between human beings and machines.


Alexandria, a city with a devastating history of catastrophic tsunamis, is extremely vulnerable to a new cataclysmic tsunamic event at any moment, especially with its current high density coastal communities and the rapidly increasing population rates. Most of the city's inhabitants are living in low lying land, even below sea level. The hazard of being attacked by a tsunami has been classified by many scientists as 'likely' and the city has been identified as one of the 'Mediterranean tsunami vulnerable cites,' were there is a great need to implement mitigation and preparedness measures and an advanced tsunami warning system. This paper aims to develop a practical strategic tsunami hazard analysis and risk assessment-planning model, applied on the city of Alexandria. The model will form the basis for sustainable development planners to create and utilise the appropriate tsunami planning measures and emergency evacuation plans for coastal tsunami prone areas. It would also help in calculating and predicting the amount of casualties that would occur in the case of a tsunami attack without any mitigation or preparedness measures.


It has been suggested that the efficiency and economics of a flexible manufacturing system can be improved through judicious grouping of machines and parts. This paper addresses the formulation of families of parts requiring similar manufacturing with closely related machines using the topological concepts of polyhedral dynamics (i.e. q-analysis). An introduction to the concepts of q-analysis is presented and is followed by a discussion of the application to machine-part group formation. Two examples from the literature are presented and the resulting part groupings compared. The results suggest that q-analysis not only provides part grouping capabilities equivalent to current techniques, but also provides additional qualitative information. Measures are available which provide insight into the importance of particular groupings and the strength of the interaction between the groups. The analysis also identifies machines with are potential bottlenecks, and parts whose availability may impact the manufactu...


Several kinds of alcohol with different length of aliphatic chain were used as cosurfactant in water/monoethanolamine oleate-alcohol-diesel oil microemulsion systems.The effects of alcohol on microemulsion were discussed in detail.Standard free energy change(ΔGΘc→i) for alcohol to transfer from continuous phase to interfacial membrane was investigated and calculated by the method of dilution.It was found that the diesel oil microemulsion systems could be formed just with the alcohol with more than 3 carbon numbers.The area of microemulsion regions and maximum water content of diesel oil microemulsions were increased with the aliphatic chain length of the alcohol.The values of ΔGΘc→i were negative when the diesel oil microemulsions were formed by alcohol with 4-8 carbon numbers.The linear relationships existed between-ΔGΘc→i and the carbon atom number of alcohol.The optimum aliphatic chain length of alcohol for forming stable diesel oil microemulsion was 7 or 8 carbon number and the value of HLB was 8.5.


ABSTRACT:In this essay, I argue that the temporal figure of latency is central for an understanding of the material temporalities of media. Latency as a temporal figure is built into the material functioning of sound reproduction and audiovisual media. The discussion shows how latency underpins technical processes of storing and reproducing sounds and moving images in a broad sense, while analyzing mediatic latency in Twelver Shi'i media practices in Mumbai. The focus on latency as a key temporality of media is also useful for thinking about Twelver Shi'i ritual life and media practices because the temporal figure of latency features very prominently in Shi'i eschatology and ritual life. Mediatic latency and the latency built into Shi'i ritual life and cosmology interact in highly significant and productive ways, reinforcing a complex of piety and ritual commemoration that nowadays is thoroughly integrated with audiovisual media practices. The media practices studied mobilize different affordances of contemporary media, such as creating contemporaneity with the non-contemporaneous and the invocation of linear progress for different religious ends.

SINCE THE 1980S, THE BRITISH GOVERNMENT HAS ACTIVELY PROMOTED THE ROLE OF the private security industry within the criminal justice system. Privately run prisons, young offender institutions, and secure training centers for children aged 12 to 17 years old are now acknowledged components of the criminal justice landscape. Added to this, new immigration detention centers have been opened by commercial organizations to supplement their crime control interests and to create a broader market in incarceration. The electronic monitoring (EM) of offenders and, more recently, those subject to immigration controls represents another growth area in public-sector privatization and the extension of commercial forms of social control into domestic spaces. First used in 1989, over 16,000 people are now subject to a variety of forms of EM across England and Wales. Those subject to EM-based programs include bailees, adult offenders, juvenile offenders, terrorist suspects, those subject to immigration controls, and, potentially in the near future, those who refuse to pay child support. EM represents an expanding market, grounded in criminal justice privatization, that permits a much more diffuse future vision of social regulation and control. Many of the business areas where commercial criminal justice in England and Wales now flourishes are based upon original developments in the United States (Newburn, 2002) that have inspired the development of new commercial crime control markets across the globe. EM is now used in Canada, Taiwan, Singapore, Australia, New Zealand, Denmark, Finland, Sweden, the Netherlands, Germany, Belgium, Portugal, Italy, Argentina, Israel, and Scotland. Commercial crime control is an international business and EM, alongside other "techno-corrections," has be? come part of a global corrections-commercial complex (Lilly and Knepper, 1992). The processes of globalization have prompted a period of reconstruction within


Abstract The chiroptical properties of (hydroxypropyl)cellulose (HPC) in methanol are measured by optical rotatory dispersion (ORD), both in isotropic solution and in the cholesteric liquid crystalline phase. The ORD spectra of HPC films cast from lyotropic solution are also examined. Isotropic solutions of HPC in methanol provide no ORD evidence for the presence of a helical conformation, or for concentration-induced changes in conformation. The ORD curve of HPC in methanol, when expressed as specific rotation, is independent of polymer concentration for isotropic solutions containing between 1 and 43 per cent polymer by weight. From the slope of Drude plots, the Cotton effect responsible for the observed ORD curve occurs at 175–180 nm. However a 45 per cent liquid crystal-line solution exhibits plain positive dispersion, and the magnitude of the specific rotation is also much greater than that found for solutions containing less than 43 per cent polymer. Results for more concentrated solutions confirm t...


A new series of bis-4,6-sulfonamidated 5,7-dinitrbenzofuroxans  7–11 had been synthesized and tested for antimicrobial activity. The structures of new sulfanilamide derivatives were characterized by elemental analysis, IR spectroscopy, and mass spectrometry (MALDITOF). The synthesized compounds were tested for their in vitro antimicrobial activity using the disk diffusion method against Gram-positive bacteria Staphylococcus aureus; the Gram-negative bacteria Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis; the fungal strain Aspergillus niger; and the yeast-like pathogenic fungus Candida albicans. Our results indicate that the compounds 7–11 exhibit potent antimicrobial activity. The stability of the compounds was evaluated by TG and DSC methods.


Efficient data collection using wireless sensor networks (WSN) today focuses on the hot topics of smart agriculture and precision farming. Agricultural WSNs, however, often face many problems, including multitasking, variability, and transmission rate. In this paper, we provide a practical solution that takes advantage of the many data collection tasks in smart farming enabled by wireless sensor networks created enabled by edge computing. The next phase is a cutting-edge data collection system that combines edge computing and wireless sensor technology. The data collection system is made by modeling a variety of sensors and processes. The optimal workstation and wireless sensor are then selected on the edges of the network server, taking into consideration each unique job and the relationship between both the task and the sensor, to satisfy the accuracy of the information and the time constraints of information-gathering activities. We also design a data collection procedure that takes into consideration established criteria for information accuracy. Eventually, when the new technique is implemented, a simulation model is built and effects are evaluated and contrasted with conventional approaches. The idea outperforms the conventional approaches in metrics, according to the comparative results.

With the advent of digitization of text documents and digital communication technologies, an enormous quantity of information can be stored and transferred. However, digesting this huge amount of information is becoming an increasingly difficult task due to the time needed to read them. Furthermore, it is observed that people who searched for information does not necessary read all the information retrieved and this is especially true during the initial search for information. During the initial phase, people are keen to find out how relevant is the information retrieved. This research describes SmartView, a system that displays only a portion of a text file which is of interests to the reader. SmartView opens a text file, extracts and displays a list of useful words contained in the file. It then compiles and displays its initial view of the file. A view of the file is compiled based upon sentences that contain the words of interests and their anaphors and their lexical chains. Initially, the word that appears most frequently in the text (ignoring simple words such as prepositions, articles, etc.) is used. User can click on the list of useful words displayed to change the view and in doing so, the user sees the file according to his/her interests. A view of the file is displayed in a (linear) tree form so that only the key sentence in each paragraph is displayed. Nonetheless, user can click on the node of a tree to read more. User can also decide how much of a view to see. Options include 25%, 50%, 75% and 100%. In addition to a list of sentences being displayed, a view file also contains a graphic display showing the approximate whereabouts in the text of each of the sentences being displayed in the view.


'Shuhui 528'and sterile lines'Ⅱ-32 A'were taken as material to study the dynamic change of leaf age,birth process change,population growth dynamic change,and the effects on the seed yield of the parents by KUBOTA SPW-48c hand transplanter planted 4,8 and 12 lines 3 seed machine inserted with image processing. The results showed that the female parent machine-transplanted had early and more tillers,but the female parent had less number of grain in a spike and uniform heading. The parents plant with the ratio of 1: 8 had good synchronization of flowering,harmonious effective panicle number and seed setting rate and high seed yield. The variation coefficient of yield components was the solid grain number the seed rate the spike number. The results of the yield components and yield of simple correlation,partial correlation analysis showed that the seed rate and spike number were very significant positive correlation with yield. The direct path coefficient of the seed rate and the spike number to output was positive,but the indirect effect of the seeding rate through spikelets to the yield and the indirect effect of the spikelets number through the seeding rate to the seed yield was negative.

A connection apparatus suitable for measuring earth resistance and built in a concrete electric pole is provided to enable a checking person to conveniently measure the earth resistance on the ground within a short time. A through-hole(21) is formed to pass through a housing(20) when a connection apparatus is installed in a concrete electric pole. A bolt hole is formed at an outer end of the housing so that the housing is expanded to have a flange shape and fixed at a molding frame for manufacturing the concrete electric pole. A resistance measuring device(30) is coupled to a fixing piece(24), which is mounted on a periphery of the housing, by insertion. A hole(31) through which an inner earth cable passes is formed at a central portion of the resistance measuring device. The resistance measuring device is comprised of a clamp-type contact tap whose one side is cut. A measuring rib(35) is inserted into the through-hole of the housing so that one side of the measuring rib interferes with a cut portion(32) of the resistance measuring device and thereby the measuring rib measures the earth resistance.


Impossible objects – 3D objects that can create a visual effect that seems impossible – can be classified by generation based on the order in which they were discovered or produced. The first generation consists of objects whose appearance when observed from a certain viewpoint matches a picture of an impossible object. Many such objects can be created, as there are multiple 3D objects that will project the same two-dimensional picture, including shapes that the human vision system is unable to perceive. The gap between the mathematical and the psychological can also create other types of "impossible" visual effects. Impossible objects are here classified into seven groups. 2012 ACM Subject Classification Applied computing → Computer-aided design


Objective:To determine the influence of pol replication capacity on the natural history of HIV-1 infection. Design:Pol replication capacity was measured using a recombinant virus single cycle assay on baseline plasma specimens from subjects enrolled in the Hemophilia Growth and Development Study. Setting:Children and adolescents with hemophilia and HIV-1 infection were enrolled at multiple sites across the USA into a natural history study. Participants:The Hemophilia Growth and Development Study enrolled 207 HIV-1-infected hemophiliacs between 6 and 19 years of age in 1989 and 1990. Subjects were followed every 6 months through 1997 with pol replication capacity measurements available from 128 of the subjects. Main outcome measures:A univariate model defined the relationship between pol replication capacity and HIV-1 RNA and CD4 T-cell number. A random effects model assessed the ability of this measure to predict CD4 T-cell decline over time and a Cox proportional hazards model and Kaplan–Meier analyses defined how it predicts clinical progression. Results:Pol replication capacity measures correlated with baseline HIV-1 RNA, R2 = 0.189 (P = 0.03) and CD4 T-cell number, −0.197 (P = 0.03). It also independently predicted CD4 T-cell decline over time and progression to AIDS. Conclusions:This study demonstrates that pol replication capacity independently influences the natural history of HIV-1 infection.


This paper describes the design, fabrication, and testing of a lightweight and compact torque sensor system based on a gradient grating period guided-mode resonance (GGP-GMR) filter and a flexure–elastic-force-sensing element. The GMR filter exhibits a characteristic resonant reflection, when illuminated with a broadband light source at normal incidence. Instead of a fixed grating period, the GGP-GMR filter consists of grating periods varying from 250 to 550 nm with an increment of 2 nm. Given the flexibility of the plastic-based GGP-GMR filter, it can be bent conform to the cylindrical surface of the flexure. The applied torque induced deformation of the flexure and angular displacement of the attached GGP-GMR. For a stationary light source, the angular displacement of the GGP-GMR filter results in illumination at different locations (grating periods), leading to a shift of the resonant reflection wavelength. The magnitude of shift in the reflection wavelength can be correlated to the magnitude of deformation and the applied torque. In addition, commercial software based on the finite element method was used to simulate the proposed design, which indicates that the flexure made of medium-carbon steel can withstand the torque of 35 Nm without yielding. Furthermore, the simulation results (torque-induced deformation) were consistent with those obtained using the proposed torque sensor system. Torque measurements from 0 to 25 Nm showed good linearity. The limit of detection achieved was 0.77 Nm.


Public facility restoration planning traditionally focused on response to natural disasters and hazardous materials accidental releases. These plans now need to integrate response to terrorist actions. Therefore, plans must address a wide range of potential vulnerabilities. Similar types of broad remediation planning are needed for restoration of waste and hazardous material handling areas and facilities. There are strong similarities in damage results and remediation activities between unintentional and terrorist actions; however, the uncertainties associated with terrorist actions result in a re-evaluation of approaches to planning. Restoration of public facilities following a release of a hazardous material is inherently far more complex than in confined industrial settings and has many unique technical, economic, social, and political challenges. Therefore, they arguably involve a superset of drivers, concerns and public agencies compared to other restoration efforts. This superset of conditions increases complexity of interactions, reduces our knowledge of the initial conditions, and even condenses the timeline for restoration response. Therefore, evaluations of alternative restoration management approaches developed for responding to terrorist actions provide useful knowledge for large, complex waste management projects. Whereas present planning documents have substantial linearity in their organization, the 'adaptive management' paradigm provides a constructive parallel operations paradigm for restorationmore » of facilities that anticipates and plans for uncertainty, multiple/simUltaneous public agency actions, and stakeholder participation. Adaptive management grew out of the need to manage and restore natural resources in highly complex and changing environments with limited knowledge about causal relationships and responses to restoration actions. Similarities between natural resource management and restoration of a facility and surrounding area(s) after a disruptive event suggest numerous advantages over preset linearly-structured plans by incorporating the flexibility and overlap of processes inherent in effective facility restoration. We discuss three restoration case studies (e.g., the Hart Senate Office Building anthrax restoration, Rocky Flats actinide remediation, and hurricane destruction restoration), that implement aspects of adaptive management but not a formal approach. We propose that more formal adoption of adaptive management principles could be a basis for more flexible standards to improve site-specific remediation plans under conditions of high uncertainty.« less


Abstract The objective of the research work was to characterize a buffalo herd in flooded conditions in Cojedes state, Venezuela, being evaluated the calving distribution (CD), calving interval (CI) and weaning weight (WW). Birth and productive records from Hato La Soledad were used to determine monthly frequencies of calving (n=2106), calving interval (n=936) and weaning weight (n=1683). The statistical analysis included year (CY) and calving season (CS), sex of calf (SC), age of cow (AC) and interactions for CI, including additionally age to weaning for WW. Results showed significant differences (P≤0.05) in CD between years associated with year-on-year changes in climatic factors and progressive stabilization of the herd. CI averaged 473.9±3.0 days ( X – ± S.E.), with a significant effect of calving month (P≤0.05). CI in the herd showed an elevated percentage (75.6%) of buffalo cows with CI lower than 400 days. The effect of age at calving was not significant doubt to the fact that the herd was young. WW averaged 130.4±1.9 kg with age to weaning of 238.7±3.2 days, with significant effect of year and calving month, and age to weaning, with a daily gain of 128 g. The results showed the productive and reproductive potential of the buffalo in tropical conditions.


Objectives: To explore the cancer prevention-related nutrition knowledge of primary health care physicians towards nutrition and its relation to the development of cancer. Materials and methods: a cross-sectional study was conducted among family physicians in Riyadh, between November 2019 and April 2020. The participants in the current study were surveyed using a self-administered questionnaire. The questionnaire included socio-economic data and data related to the association between nutrition and cancer. Results: The mean correct knowledge score for physicians is good but less than expected (26.5+5.8) 73.6%. Multiple regression revealed that age, position, and nationality to be significantly associated with knowledge of cancer prevention (P<0.05) among physicians. Conclusions: Primary care physicians have good knowledge about the relation between nutrition and cancer but not sufficient, they should have continuous nutrition educational training programs to ensure safe and sound nutritional advice to patients and for the public about the relation of nutrition and cancer.

Abstract This study was designed to determine whether or not the difference in the physical properties between white-core and non-white-core kernels of the rice varieties for sake brewing is associated with their starch properties. We used two rice cultivars for sake brewing, Senbon-nishiki and Yamada-nishiki, from three different plots in Hiroshima prefecture. Hardness values of kernels were significantly higher in non-white-core than in white-core kernels in both varieties. Vickers hardness (VH) values were lowest at the center of the kernel in both types of kernels. VH values of white-core tissues of white-core kernels were significantly lower than those of corresponding tissues of non-white-core kernels. No significant differences were observed between the two types of kernels in VH values of the surrounding translucent tissues and in the starch properties (amylose content, pasting properties analyzed using a rapid viscoanalyzer and gelatinization properties analyzed using a differential scanning calorimetry). These results suggest that the difference in physical properties between the two types of kernels of the rice varieties for sake brewing are associated with the difference in structure of endosperm cells and not in starch properties.


Lysophosphatidylcholines (lysoPCs) are a class of special structure endogenous compounds, which have the same polar head with different fatty acyls in chain lengths, fatty acyl position, degrees of saturation and different double bond location(s). The amount of lysoPCs isomers between healthy people and patients can be a clinical diagnostic indicator which may help to reveal pathophysiological changes. In this work, a method was developed to discriminate the lysoPCs by using reversed phase ultra-performance liquid chromatography coupled to quadrupole-time of flight mass spectrometry (UPLC/Q-TOF) with the utility of MSE function. Isomeric lysoPCs were distinguished based on the retention time and the peak intensity ratio of product ions. 28 plasma lysoPCs species were identified from human plasma. The plasma samples of 12 patients with lung cancer and 12 healthy persons were collected and analyzed. With principal component analysis (PCA), the identified LysoPCs metabolic profiles of lung cancer were investigated. Both ESI+ and ESI- results showed that lung cancer patients had the same 5 lysoPCs metabolic abnormality, they are sn-1 lyso16:0, sn-2 lysoPC 16:0, sn-1 lysoPC 18:0, sn-1 lysoPC 18:1 and sn-2 lysoPC 18:2. It is noteworthy that the function of isomers with the different fatty acyls position or different double bond location(s) related to lung cancer is different. This may help elucidate the action mechanism of lung cancer.

The personal competencies and the human capital of their employees are used by organisations to convert business strategy into results leading to their competitiveness. This paper aims to assess whether business strategy impacts employee competencies and whether employee competencies in turn impact the human capital in terms of value and uniqueness. This is assessed empirically using responses from 334 senior HR professionals in India. The findings from structural equation modelling (SEM) reveal that prospector strategy is positively related to three competency, adaptability, customer orientation and innovation while defender strategy is positively related to two competency, result orientation and technical expertise. Adaptability, customer orientation and innovation competency are positively related to human capital uniqueness while result orientation and technical orientation competency are positively related to human capital value. Our study supports the contingent view of competency implying that HR managers should choose their competency framework depending upon the business strategy and requirement of human capital and recruit, train employees accordingly.

General anesthesia is the fi rst choice for the patient with severe coagulopathy.


There are currently two main tendencies in Community Agriculture Policy (CAP) regulation. The first tends towards national normative structures. TheSimultaneously, a very intensive regulatory process is developed, with an increasing norm production on environment, food security and animal health. The main problem which is discussed is whether the Second Pillar will keep on developing a second order role, or if the Single Payment Scheme will vanish in a new CAP in which the environmental protection and rural development policies will become the central policy axes and market policies will be considered mainly as income stabilizers.

We study the band structure modulation and spin-Hall effect of a two-dimensional heavy-hole system with $k^3$-Rashba spin-orbit coupling (RSOC), irradiated by linearly polarized light. We find that the band structure becomes anisotropic under the illumination by the light. Most remarkably, a pair of additional spin-degeneracy points (apart from $\Gamma$ point) emerge in the energy dispersion, the locations of which are solely determined by the strength of the amplitude of the incident light. If this degeneracy occurs around the Fermi level, the spin-Hall conductivity (SHC) exhibits a resonance. Away from the degeneracy points, the light rotates the average spin polarization. The possible effects of $k^3$-Dresselhaus spin-orbit coupling are also discussed.

Gravity sampling is of vital importance for sampling seabed sediments and understanding submarine sedimentary environments and resources. In this study, a new bionic sampler tube (BST) with non-smooth surface for low-disturbance and rapid sampling is presented. The BST with depressions and swellings on its surface was designed on the model of the non-smooth surface of the dung beetle. Sufficient theoretical calculations, numerical simulations, and experimental tests were carried out to study its sampling performance. The penetration depth, sample length, and frictional drag of the sampler tube were calculated. The finite element model and the coupled Eulerian-Lagrangian (CEL) method were used to analyze and compare its sampling performance. Laboratory and field gravity sampling tests were conducted and the results demonstrated the advantages of the BST in improving sampling performance and in reducing adhesion and drag.


This study reports on a preliminary estimation of the human-horse interaction through the analysis of the heart rate variability (HRV) in both human and animal by using the dynamic time warping (DTW) algorithm. Here, we present a wearable system for HRV monitoring in horses. Specifically, we first present a validation of a wearable electrocardiographic (ECG) monitoring system for horses in terms of comfort and robustness, then we introduce a preliminary objective estimation of the human-horse interaction. The performance of the proposed wearable system for horses was compared with a standard system in terms of movement artifact (MA) percentage. Seven healthy horses were monitored without any movement constraints. As a result, the lower amount of MA% of the wearable system suggests that it could be profitably used for reliable measurement of physiological parameters related to the autonomic nervous system (ANS) activity in horses, such as the HRV. Human-horse interaction estimation was achieved through the analysis of their HRV time series. Specifically, DTW was applied to estimate dynamic coupling between human and horse in a group of fourteen human subjects and one horse. Moreover, a support vector machine (SVM) classifier was able to recognize the three classes of interaction with an accuracy greater than 78%. Preliminary significant results showed the discrimination of three distinct real human-animal interaction levels. These results open the measurement and characterization of the already empirically-proven relationship between human and horse.


Slow speed bearing is the most critical component for the rotary machinery running at lower speeds. So there is need for the vibration monitoring of bearing to detect fault at early stage. Examples of bearings used in slow speed machinery are paper mills, wind turbine power plant, air preheaters and conveyor belts used in mining industries. Defect detection in slow speed bearing is difficult since high noise to signal ratio and also weak bearing defect signal. At such low speeds the energy released from bearing defects is small and coupled with surrounding noise.
Identification of the signals of defective slow speed thrust ball bearing of mechanical components in the presence of external vibration is a difficult task. Therefore, this research work has been carried out to improve the defect detection of slow speed thrust ball bearing in presence of external vibration using self-adaptive noise cancellation (SANC). Circular defect (diameter = 400µm) is present on the inner race of the bearing and external vibrations have been imparted to the defective bearing with the help of running compressor. It has been noticed that the defective bearing signal to noise ratio has been significantly improved after the implementation of SANC. The noise has been suppressed and the defect frequencies are clearly visible in the vibration spectrum. In this report in SANC technique the least mean square (LMS) algorithm has been used.


Range-based localisation and tracking methods use the time-of-arrival (TOA) between the mobile station and several base stations, but the multipath propagation of non-line-of-sight channels complicates the estimation and processing. For channel modelling, the Gaussian scatterer distribution model has been reported to have a reasonable match between its TOA probability density distribution (PDF) and measured TOA data. In this study, this TOA PDF is adapted, along with selection from multiple motion models of the mobile station, for a new location and tracking algorithm. Since the TOA PDF is non-Gaussian and is a non-linear function of the position of the mobile, particle filtering is used which increases the complexity of the algorithm. The focus is on the tracking performance, and this is evaluated by simulation using idealised statistical channels, allowing direct comparison between different location algorithms. In this context, the presented algorithm is more accurate than the benchmarks of extended Kalman filter tracking, and positioning using least squares.


This article considers how Ivan Vladislavić's Double Negative, and to a lesser extent Portrait with Keys, represents the city of Johannesburg and the state of the nation as an ever-shifting interregnal space that is at once seized in a perpetual state of uncertain becoming, but also implosion, collapse and decay. It contemplates how these narratives relate to the macro-politics of the post-transitional nation state as being in the throes of, what the anthropologist Robert Thornton describes as, a 'constant sense of suspense' (1994). Drawing on Double Negative's allusive use of Paul Klee's 'Angelus Novus', the article considers this motif as a symbol of transition and interregnum, not teleology, in writing the post-apartheid South African city. In making capital of Walter Benjamin's essay, 'Theses on the Philosophy of History' (1950), the article will read both literary city and nation in terms of Michael Titlestad's conceptualization of the 'mezzanine ontology' (2010) as a descriptor of the condition of post-apartheid liminality.


We investigate the impact of the wireless network's physical layer (PHY) security and reliability on demand-side management operation in the smart grid. We assume that consumers communicate their energy demands with the utility, and we investigate the tradeoff between the wireless network's PHY security and reliability. We consider passive and active attacks on the smart grid, and show their impacts on both the wireless communications system's reliability and security. To improve the wireless communications system's security, we propose an artificial-noise (AN)-aided scheme for orthogonal-division multiplexing-based wireless systems. We show that increasing the PHY security of the legitimate transmissions decreases the communication reliability between the smart meters and the meter data-management system since to secure the transmissions, a portion of the transmit powers will be assigned to AN signal transmissions. To further secure the smart meters' transmissions and enhance their reliability, we propose a new encoding scheme where the data are encoded over the available smart meters' communication (i.e., non-idle) times in a given hour.

Online experimentation, also known as A/B testing, is the gold standard for measuring product impacts and making business decisions in the tech industry. The validity and utility of experiments, however, hinge on unbiasedness and sufficient power. In two-sided online marketplaces, both requirements are called into question. The Bernoulli randomized experiments are biased because treatment units interfere with control units through market competition and violate the "stable unit treatment value assumption"(SUTVA). The experimental power on at least one side of the market is often insufficient because of disparate sample sizes on the two sides. Despite the importance of online marketplaces to the online economy and the crucial role experimentation plays in product development, there lacks an effective and practical solution to the bias and low power problems in marketplace experimentation. In this paper we address this shortcoming by proposing the budget-split design, which is unbiased in any marketplace where buyers have a finite or infinite budget. We show that it is more powerful than all other unbiased designs in the literature. We then provide a generalizable system architecture for deploying this design to online marketplaces. Finally, we confirm the effectiveness of our proposal with empirical performance from experiments run in two real-world online marketplaces. We demonstrate how it achieves over 15x gain in experimental power and removes market competition induced bias, which can be up to 230% the treatment effect size.


Thanks to the characteristics of table tennis, different recreational players can have different aims. The movement intensity varies with such aims. It can be expected that the energy consumption in different levels will be remarkably different. In competitive table tennis, the movement intensity varies with skill levels. For athletes at a lower skill level, it is difficult to compete continuously, and the sphere of action will be relatively limited, which consequently reduces the energy consumption. Opposite is true for the athletes at a higher skill level. So far, in order to investigate the relationship between movement intensity and energy consumption among different athletic levels, typical junior high school students and skilled university students have been tested as experimental subjects, and the energy consumption over a 60-minute table tennis practice has been surveyed. In competitive table tennis, for advancing the contestants' skill, the implementation method of the physical ability and the training should be investigated. Therefore, in this paper professionalcontestants are tested as subjects to investigate and compare a variety of pulse rates and energy

EPA initiated a study of selected water utilities in which data were collected from at least one Class A water utility in each of EPA's 10 regions. To facilitate data comparisons, each utility's costs were subdivided into the functional area of acquisition, treatment, power and pumping, transmission and distribution, and support services. Costs were also categorized as being either operating or capital costs. These data indicate a general trend in the increasing demand for water, increasing labor wage rates, and in increasing costs of other operating and capital expenses associated with water supply. Labor costs account for more than 40% of total operating costs. It is estimated that the cost of water supply will increase by 59% between 1975 and 1980 due to normal demand and inflationary pressures. The add-on technology required to meet proposed provisions of the Safe Drinking Water Act will increase water supply costs by another 22%.


It is known that three different solid solutions, (Na0.88K0.12)VO3, (Na0.5K0.5)VO3 and Na(V0.66P0.34)O3, form in the (Na,K)(V,P)O3 system. These compounds all have monoclinic crystal structures similar to the pure alkali metal metavanadates containing small cations, e.g. Li+ and Na+ (Space group C2/c). Metavanadates with large cations like K+, Rb+, C+s and NH+4 form orthorhombic crystals, space group Pbcm. All those are structurally related to the silicate pyroxenes. Na(V0.66P0.34)O3 and (Na0.88K0.12)VO3 have the same modified diopside structure as (alpha) - NaVO3 while (Na0.5K0.5)VO3 adopts the true diopside structure. The infrared spectra of the three solid solutions are reported here in comparison with those of (alpha) -NaVO3 and KVO3. The results are also correlated with those obtained in two independent high pressure Raman studies of NH4VO3 and RbVO3 as the introduction of a larger cation like K+ should increase the pressure in the structure.


The energy parameters of a faceted concentrator 5 m in diameter have been investigated. The facets were in the form of hexagonal paraboloids mounted on a paraboloidal base. This gives an effective working area that is 10 percent greater as compared with a concentrator using circular facets. The power generated in the focal plane of the concentrator was 9.0 kW for an incident radiation of 784 W/m/sup 2/.
