In this paper, the theory of the fractional singular Lagrangian systems is investigated with second-order derivatives. The fractional quantization for these systems is examined using the WKB approximation. The Hamilton–Jacobi treatment can be applied for these systems. The equations of motion are obtained. The Hamilton–Jacobi partial differential equations are solved to determine the action function. By finding the action function, the wave function for these systems is constructed. We achieved that the quantum results are agreement with the classical results. Besides, to demonstrate the theory; two mathematical examples are examined.


Incentives have been proposed to National Health Service (NHS) hospitals to encourage the collection of "quality" umbilical cord blood (UCB) to treat people with blood disorders. As UCB is collected immediately after a woman has given birth, maternity practices have come under scrutiny. Sixty-two interviews were conducted between 2009 and 2010 with those working on maternity wards, and in UCB collection and banking. Ethical approval was granted by the university institution and the NHS Research Ethics Committee. Participants perceived a conflict between acquiring a "quality" UCB sample for blood disease sufferers and concerns for maternal and neonatal health. Options to overcome the conflict were compromises that demonstrated that those most powerful in the debates are those conducting maternity practices, whilst those involved in the banking of UCB have less influence perhaps as a consequence of the lower priority of "quality" UCB collection in relation to maternal and neonatal health.


Fatigue of 8 complex alloys based on Fe-13Cr-15Ni-2Mo-2Mn-0.2Ti-0.8Si- 0.06C, and single-crystal Fe-15Cr-15Ni, implanted with 400-keV B[sup +] and 550-keV N[sup +] (total dose 2.3[times]10[sup 16] ions/cm[sup 2]) was examined. 600 C creep was also examined. The dual implantation increased hardness but decreased fatigue life of the 8 complex alloys. An optimum strengthening level and a shift to grain boundary cracking were determined. The single crystals also showed reduced fatigue life after implantation. High temperature creep of E1 and B1 alloys were improved by the dual implantation. Four polymers (PE, polypropylene, polystyrene, polyethersulfone) were implanted with 200keV B[sup +] to 3 different doses. PS was also implanted with both B[sup +] and Ar[sup +]. Near-surface hardness and tribological properties were measured. The hardness increased with dose and energy; wear also improved, with an optimum dose. (DLC)


Under a constant decree agreement in 1988, LTV Steel Co. installed an activated sludge biological treatment facility at the Warren works to treat coke plant wastewater prior to discharge to the city of Warren publicly owned treatment works. This discharge is required to meet effluent quality limits for phenol and ammonia, and suspended solids are subject to surcharges. the discharge limits imposed by the city of Warren are shown in Table 1. To meet these effluent discharge limits, the original treatment strategy was to process the coke plant wastewater through an ammonia steam stripping still to control ammonia, and process the ammonia-stripped wastewater through the activated sludge biological treatment unit to control phenol. This strategy was unsuccessful because of limitations of the ammonia still, the general composition of the wastewater and the operating conditions of the biological treatment process. This article discusses the upgrading of the biological treatment process operation to meet the required discharge effluent quality.

Furthermore is disclosed an assembly for connecting a source of intravenous fluid to a patient, the assembly comprising a sealed sterile packaging enclosing the disposable cassette, a first tube for connecting said source of intravenous fluid to the inlet port of the disposable cassette, and a second tube for connecting the outlet port of the disposable cassette to an intravenous catheter.


A comparative study of the breeding behaviour of the Augur Buzzard Buteo augur was made in two contrasting areas on the southern side of Lake Naivasha, Kenya. Hell's Gate National Park represented a natural site, and the lake environs an agricultural site. Locations of adult birds and their activity time budget during the breeding cycle were studied fromApril to October 1995. Factors influencing prey delivery and nestling feeding rates, and intra-/inter-specific interactions were given special attention. Augur Buzzard pairs in the lake environs spent more time caring for chicks than their counterparts in Hell's Gate. This was apparent in the increased maternal care and paternal foraging which resulted in larger broods and more prey deliveries to nests respectively. Prey and biomass delivery rates to nests showed an increasing trend as the nestling period progressed. This was significant in the lake environs where brood sizes were larger than in Hell's Gate. Overall nestling feeding rates were also significantly greater in the lake environs than in Hell's Gate. Augur Buzzards in Hell's Gate spent significantly more time interacting with conspecifics and other species compared to those in the lake environs. We suggest that reduced predation pressure from conspecifics and other raptors in the lake environs as a result of lower inter-/intra-specific interactions enabled Augur Buzzards to maximise provisioning of their young hence potentially increasing productivity.

Inclusion of an extra stage and compensation network in the proposed amplifier enhanced the performance over the conventional folded. The proposed circuit offers good trade‐off on the conflicting performance parameters such as bandwidth, slew rate, d.c. gain, phase margin and settling time. The simulation has been carried out on Tanner EDA tool on TSMC 180 nm technology.


This paper provides an overview of the state-of-the art and the current research trends concerning shortest paths problem on dynamic graphs. The discussion is divided in two main topics: reoptimization and time-dependent shortest paths. Reoptimization consists in the solution of a sequence of shortest path problems in which each instance slightly differs from the previous one. The reoptimization tackles this problem wisely using information stored in an optimal solution previously computed. On the other hand, shortest path problems on time-dependent graphs are characterized by a weight function which not only depends upon the arcs but changes in time according to a certain time horizon.


In this paper, we report our efforts to recognize human contexts through the things sensorized by our sensor platform. As you know, many things wearing on your body have already become a sensor to understand our activities. Most famous things are watches and glasses. In the future, we suppose that unwearable things, such as cutlery, sport gear and instruments, would be also a sensor for recognizing our activities. Compared with our movements, the movement of unwearable things will have more variation. Also, suitable sensor and proper algorithm would be different according to the things. To enhance the senserization of various things, we have proposed a platform, called SenStick, that consists of ultra tiny all-in-one sensor board and sophisticated mobile app. If using it, every researcher can try embedding various sensor into various things and can focus on data analysis. We explain the possibility of smart experiment platform with introducing various sensorized things on the platform.

Abstract Background Cognitive deficits are prevalent among patients with schizophrenia and are robustly associated with functioning and outcome. Although cognitive deficits are known to be present at the prodromal phase and to worsen at the onset of the disease, the long-term course of cognitive impairments are less well established. Many studies have focused on first episode psychosis with relatively short lengths of follow-up. Thus, the aim of this study is to investigate changes in cognitive performance of chronic schizophrenia patients in a variety of neurocognitive tests over a seven-year test-retest period. Methods We will contact 85 patients with schizophrenia (as defined by the DSM-IV-TR), considered clinically stable in the previous year, who participated in a study about the deficit syndrome of schizophrenia carried out in 2009 and 2010. Back then, they were recruited in two sites: an outpatient psychiatric service of a university general hospital (49 patients) and a community-based mental health service for patients with severe mental illness (36 patients), both in Campinas, Sao Paulo, Brazil. Patients will be assessed with the same instruments adopted in the first study: a questionnaire for clinical and demographic information; SAPS, SANS, Calgary Depression Scale and a battery of neurocognitive tests comprising: Digit Span Forward (DSF), Digit Span Backward (DSB), Rey Complex Figure Copy (RCFC), Rey Complex Figure Memory (RCFM), Digit symbol-coding (DSC), Picture Completion (PC), Matrix Reasoning (MR), Vocabulary (V), Trail Test A (TTA), Trail Test B (TTB), Phonological Fluency (PF) and Semantic Fluency (SF). To test differences in neurocognitive performance, and in symptoms severity at base and at follow-up we used the Wilcoxon Test. Results We present in this poster partial results. Among the 20 reassessed patients the mean age at baseline was 36.9 ± 8.9 years, mean duration of mental illness was 16 ± 10.1 years, 75% were men. They had, in mean, 10.7 ± 3.3 years of education, only 20% had any work activity, and 15% were married. Mean length of test-retest interval was 6.9 years (minimum 6 and maximum 7.7). At follow-up, 4 patients had improved their education, but only 3 (15%) had any work activity. Up to now 19 patients completed the cognitive reassessment. Severity of positive and of depressive symptoms was low at base line (mean score on SAPS 5.5 ± 4.8; mean score on Calgary 1.5 ± 1.9) and remained low at follow-up (SAPS 6.2 ± 4.4, Calgary 2.2 ± 2.2), with no significant change. Patients, as a group, had moderate negative symptoms were at baseline (mean SANS score 10.5 ± 6.9) and had their negative symptoms worsened at follow-up (SANS 14.8 ± 7.1), p=0.005. Patients had a worse performance at follow-up in 4 out of 12 tests: DSF (3.8 ± 1.5 at follow-up versus 10.1 ± 2.8 at baseline, p < 0.000), DSB (3.4 ± 1.9 at follow-up versus 4.3 ± 2.2, p=0.005), RCFC (14.8 ± 9.4 versus 30.2 ± 8.6, p < 0.000) and RCFM (5.9 ± 6.5 versus 13.9 ± 9.8, p < 0.000). In the remaining 8 tests: DSC, PC, MR, V, TTA, TTB, PF and SF, there were no significant differences in performance between baseline and follow-up assessments. Discussion Our preliminary results are derived from a small sample. Although we cannot draw definite conclusions, we identified different patterns of longitudinal course for different cognitive domains with attention, shot-term memory, working memory, visual-spatial ability and executive functions presenting a decline over time; whereas other domains, such as visual memory, visual perception, learning memory, verbal comprehension, motor function, remaining stable in patient through patients' 4th and 5th decades of life.


The hydrolysis of arginine to ornithine and urea is catalyzed by arginase in the last step of the urea cycle. We examined a group of arginase deficient patients by PCR-SSCP analysis to characterize the molecular basis of this disorder. A heterogeneous population of nonsense mutations, microdeletions, and missense mutations has been identified in our cohort. Microdeletions which introduce premature stop codons downstream of the deletion and nonsense mutations result in no arginase activity. These mutations occur randomly along the gene. The majority of missense mutations identified appear to occur in regions of high cross-species homology. To test the effect of these missense mutations on arginase activity, site-directed mutagenesis was used to re-create the patient mutations for in vivo expression studies in a prokaryotic fusion-protein expression system. Of 4 different missense mutations identified in 6 individuals, only one was located outside of a conserved region. The three substitution mutations within the conserved regions had a significant effect on enzymatic activity (0-3.1 nmole/30min, normal is 1300-1400 nmoles/30min, as determined by in vitro arginase assay), while the fourth mutation, a T to S substitution, did not. In addition, site-directed mutagenesis was utilized to create mutations not in residues postulated to play a significantmore » role in the enzymatic function or active site formation in manganese-binding proteins such as arginase. We have determined that the substitution of glycine for a histidine residue, located in a very highly conserved region of exon 3, and the substitution of a histidine and an aspartic acid residue within a similarly conserved region in exon 4, totally abolishes enzymatic activity. Mutations substituting glycine for an additional histidine and aspartic acid residue in exon 4 and two aspartic acid residues in exon 7 have also been created. We are currently in the process of characterizing these mutations.« less


ABSTRACT This study investigates the effects of childhood sexual abuse for male and female survivors, characteristics of the abuse experience, current coping strategies, and current psychological adjustment. Nineteen male and 59 female adult survivors of childhood sexual abuse, recruited from both local and national support groups, completed a background questionnaire, dispositional coping inventories measuring current and retrospective abuse-specific coping styles, and measures of current psychological adjustment. In response to sexual abuse experienced during childhood, avoidance coping emerged as the most frequently used strategy by both sexes. Although there were no gender differences in current use of problem-focused and avoidance strategies, males related more use of acceptance whereas females utilized more emotion-focused coping. In general* females reported significantly greater trauma-related distress than males, including higher levels of anxiety, depression, and post-trauma symptoms.


Impulse turbine is widely used device as an energy converter in OWC type wave plant especially in Korea because of the wide operating range. Because the driven torque of blade is extracted form wave energy which is not an infinity force like fossil energy source, study on the unsteady characteristics of turbine such as self-starting performance are important to predict the performance of pilot plant in real sea conditions. The transient calculation method for performance prediction of OWC impulse turbine is proposed in the present paper using commercial CFD code Fluent, which is supposed to provide more valuable unsteady information during self-starting and rotating of the turbine. The rotation of turbine is derived from the angular acceleration, which are obtained from torques integration on rotor blades. The frictions and electricity generator loading are regarded as the counteractive force contributing to the above torque calculations. The experimental study is carried out using wave simulator test rig which can simulate a sinusoidal flow in test section. The RPM of turbine, torque of blade and pressure different induced by turbine are measured to study unsteady characteristics under variable flow and resistance loading conditions.


Studies were conducted to examine whether an experimental additive solution (EAS‐2) containing, in mM: 20 NH4Cl, 30 Na2HPO4, 2 adenine, 110 dextrose, 55 mannitol, pH 7.15, would be useful to extend the storage shelf life of human RBCs. With 6 pairs of split units, ATP concentrations were better maintained for 12 weeks with EAS‐2 than with Adsol® (1.8 vs. 1.1 μmol/gHb, respectively, p = 0.002). Autologous 24‐hours 51Cr viability values for split units in the same donors were: on 6 paired units at 8 weeks, EAS‐2 87.0±4.5%, Adsol 72.6±2.3%, p = 0.004; on 11 paired units at 9 weeks, EAS‐2 79.5±7.1%, Adsol 68.2±10.1%, p = 0.0003. The data suggest that packed RBCs stored for 9 weeks with EAS‐2 will be suitable for transfusion following the removal of supernatant with a single washing step.


Fringe waves represent the diffracted field generated by the nonuniform/fringe surface currents concentrated in vicinity of sharp scattering edges. For perfectly conducting wedges, they have been studied in a number of publications. In this communication, fringe waves for a wedge with one face electric and the other magnetic are analyzed analytically and numerically.


In diagnostic radiology, quality control programs (QCP) are applied to promote the optimization of the performance of equipments and processes that generate the radiographic image. This ensures the generation of image with the quality needed to secure the diagnosis, and the optimization of radiological protection necessary to reduce the dose of radiation absorbed by the worker and patient. Determining the causes associated with the rejection of radiographic images is the action that starts the process of deploying a QCP in radiology service. In order to deploy a QCP in a medium-sized hospital, the study is carried out in order to determine the percentage of rejection of the images produced by the Department of Radiology at this hospital, as well as the causes related to this rejection. The results indicated a percentage of rejection of images of 14% caused by problems in the processing of the radiographic films and inexperience of technical trainees, and the monthly average for the period is 8%. After the application of QCP, the percentage of the monthly average was reduced to 5%.


Three hundred and four male and female 7 - to - 9-year-old children from one public and one private school in Maringa were investigated to verify flatfoot incidence. Footprint diagnosis was obtained through a static podogram. Flatfoot incidence was observed in 24.34% of the children, of which 66.2% were males and 33.8% were females, showing a statistically significant difference. A predominance of flatfoot in children from the private school was verified. The condition occurred in greater proportion in white (25%), followed by mulatto (23%) and black (19%) children, but the differences were not statistically significant. The greater incidence of flatfoot in boys and in children from the private school may suggest that the continuous wearing of shoes has caused negative consequences to the feet morphophysiology.


ABSTRACT
Little is known about the effectiveness of placebo interventions in patients with non-specific low back pain (LBP). This systematic review assessed the magnitude of the effects of placebo interventions as compared to no intervention in randomized controlled trials(RCTs) including patients with LBP. Embase, Medline(Ovid) and Cochrane CENTRAL databases were searched from inception to December 5th, 2019. RCTs comparing placebo intervention versus no intervention in adult patients with non-specific LBP were included. Pain intensity, physical functioning and health-related quality of life (hrQoL) measured at short-, medium- and long-term follow-up were the outcomes of this review. Twenty-one RCTs were included; one concerning acute LBP and one sub-acute LBP, while 19 studies reported on chronic LBP. In chronic LBP, placebo interventions were more effective than no intervention at short-term for pain intensity [standardized mean difference (SMD) = -0.37, 95% CI = -0.55 to -0.18, moderate quality evidence], physical functioning (SMD -0.19, 95% CI = -0.39 to 0.01, moderate quality evidence), and physical quality of life (Mean Difference = -2.71, 95% CI = -4.71 to 0.71, high quality evidence), respectively. These effects were not significant at medium-term follow-up and no data was available at long-term follow-up. These results show placebo interventions are more effective than no intervention at short-term in patients with chronic LBP. However, the magnitude of the effects is probably not clinically relevant (approximately 8 points on a 0-100 pain scale). Future research should identify effect modifiers and causal mechanisms explaining the short-term effects of placebo interventions in patients with chronic LBP.

The study of neutron-rich nuclei near Sn is interesting and important for both nuclear structure and nuclear astrophysics. For a considerably large model space allowing cross-shell excitations, a new effective Hamiltonian is determined by employing the extended pairing-plus-quadrupole model with monopole corrections. Calculations for two mass regions, for the north-east quadrant of Sn with Z > 50 and N > 82 and for the south-west quadrant with Z < 50 and N < 82, have been performed recently. The structure of these nuclei is analyzed in detail, and the role of the monopole corrections can be clearly seen.

The purpose of this study was to determine the effect on recall of presenting numerical data in several different chart formats. The formats used in this study were bar, line, table, and line-table. The three types of quantitative recall that were tested were specific amounts, and static and dynamic comparisons. It was also of interest to determine whether cognitive style (FD/FI) interacted with the ability of the subjects to recall information in any particular chart format.


Metoclopramide, a prokinetic drug, is widely used to treat vomiting and nausea. Delayed gastric emptying and continual stress are considered important factors, among others, that induce nausea and vomiting. One gastrointestinal motility regulatory factor has been assumed to be the induction of changes in the levels of peptides such as gastrin, somatostatin, motilin, and cholecystokinin (CCK) in plasma. In contrast, adrenocorticotropic hormone (ACTH) and cortisol are used as indicators of stress. Here, we studied the effects of metoclopramide on human plasma gastrin‐, somatostatin‐, motilin‐, and CCK‐like immunoreactive substances (ISs) and ACTH‐IS and cortisol under stress conditions using repetitive blood sampling in healthy subjects. Metoclopramide hydrochloride at a dose of 30 mg or placebo was orally administered to five healthy male volunteers. Blood samples were taken before and 20, 40, 60, 90, 120, 180, and 240 min after administration, subject to extracting procedures, and submitted to a highly sensitive enzyme immunoassay system. A single administration of metoclopramide caused significant increases in plasma somatostatin‐IS levels compared with the placebo. Metoclopramide significantly decreased plasma gastrin‐ and suppressed ACTH‐IS and cortisol levels compared with the placebo. We hypothesize that metoclopramide might have an accelerating gastric‐emptying effect and a modulatory effect on the hypothalamo‐pituitary‐adrenal (HPA) axis and the autonomic nervous function. These effects might be beneficial in stress‐related diseases, which suggest that this medicine has clinicopharmacological activities.

To decrease the influence of friction on control accuracy of servo system, the fuzzy sliding mode (SMC) control was put forward. Firstly, based on the Stribeck friction model, a sliding mode controller was set up, Then, to relieve the chattering problem, the fuzzy method was used to adjust the plus of the sliding mode controller, Finally, the simulation experiment was put up to compare control accuracy of these two controllers. The simulation results show that the fuzzy sliding mode controller improves the tracking accuracy, and relieves the chattering problem substantially.


The Federal Aviation Administration (FAA) Next Generation Air Transportation System (NextGen) is implementing new capabilities that rely on the support of automation to improve air traffic eficiency and predictability while maintaining safety. One issue that needs to be addressed regarding such new forms of automation - primarily as decision support tools - support is the possible impact on human performance such as knowledge and skill degradation. In particular, the question is whether after long-term use air traffic controllers will be able to effectively revert back to previously used manual operations if the automation becomes unavailable due to some degradation or failure. Based on this concern, this paper focuses on lessons learned from past experiences with the long term use of automation. To explore this issue, 21 experts were interviewed from four different domains: naval operations, medicine, nuclear power plant operation, and aviation. Three distinct job positions were interviewed within the domain of aviation: Airline dispatchers, pilots, and air traffic controllers. Two fundamental questions were addressed: 1.Can the introduction of automation have unintended negative impacts on human performance? 2.What mitigation strategies can be used to avoid or reduce these potential negative impacts on human performance and on system performance? Based on these data, five potential negative impacts of automation that were identified: •Degradation of Knowledge and Skill; •Reliance on Automation as the Primary "Agent" to Detect Problems; •Reduced Attentiveness and Preparation to Deal with Automation Degradations or Failures; •Alarm Fatigue, False Alarms, and Ignoring Alarms; •Automation-Induced Effects on Team Situational Awareness and Teamwork. In addition, six strategies to mitigate these potential negative impacts were documented: •Providing Effective Training and Experience; •Supporting Effective Teamwork; •Learning from Past Performance with Data Analytics; •Developing and Using Contingency Procedures and Checklists; •Designing Technology to Support Effective Human-Automation Teaming.


Density-Functional-Theory (DFT) provides a general framework to deal with the ground-state energy of the electrons in many-atom systems. Its history dates back to the work of Thomas [1], Fermi [2] and Dirac [3] who devised approximate expressions for the kinetic energy [1, 2] and the exchange energy [3] of many-electron systems in terms of simple functionals of the local electron density. These ideas were further elaborated in the Xα method of Slater [4], until finally, the foundations of the modern theory were laid down in the mid-sixties by Kohn and collaborators [5, 6]. Since then but particularly in the last two decades the number of applications of DFT to electronic structure problems has grown dramatically. Today DFT is the method of choice for first-principles electronic structure calculations in condensed phase and complex molecular environments. DFT based approaches are used in a variety of disciplines ranging from condensed matter physics, to chemistry, materials science, biochemistry and biophysics. There are several reason for this success: (i) DFT makes the many-body electronic problem tractable at a numerical cost of self-consistent-field single particle calculations; (ii) despite the severe approximations made to the exchange and correlation energy functional, DFT calculations are usually sufficiently accurate to predict materials structures or chemical reactions products; (iii) currently available computational power and modern numerical algorithms make DFT calculations feasible for realistic models of systems like e.g. an interface between two crystalline materials, a carbon nanotube, or the active site of an enzyme.


Optical rotation, mutarotation, and bromine oxidation measurements are reported for seven heptoses. The results reveal striking similarity in the proper ties of the sugars classified in the following groups: (1) a-l-arabinose, a-d-galactose, a-d-a-mannoheptose, and a-l-,8-guloheptosej (2) ,8-I-arabinose CaCI 2 .4H 2 0, ,8-d galactose, ,8-d-a-mannoheptose j (3) ,8-d-glucose, and ,8-I-,8-galaheptose j (4) a-d lyxose, a-d-mannose, and a-l-a-galaheptosej (5) ,8-d-gulose and ,8-d-a-glucoheptose. The marked parallelism is evidence that the sugars in each group have like con formations for the pyranose ring. The structural characteristics of the alpha and beta sugars are discussed in relation to their reactions and their nomenclature. The rates of reaction and other properties indicate that there is an important structural difference in the alpha and beta sugars. This difference is in accord with the concept that the pyranose ring is of the strainless multiplanar type rather than monoplanar. The application of Hudson's rule for selecting the alpha and beta names is considered, and it is suggested that an additional criterion be added to this rule in order to obtain a nomenclature for the carbohydrates and their derivatives, based on the most fundamental structural properties in relation to the optical rotations, together with the theory of optical superposition. Comparisons of the optical rotations of the hexose sugars give values for the rotational differences which may be grouped according to the configurations of the neighboring atoms. The rotational differences obtained from substances of similar or related configuration agreej the rotational differences obtained by the comparison of substances


The new millennium brought challenges and paradigms for metrology. Scenarios like telecommunications, information technology, and computers have demonstrated that the speed of technological development hardware currently exceeded software. Modern computer machines have broadened their velocity and storage capacity, it is now common to speak of storage in terabytes. The field of scientific metrology is close to discovering the electronic mass standard based on Avogadro s number (6,025⋅10-24) or watt balance, which will broaden measurement accuracy. Soon, when we see a young womanwith a facial mole, it may be an ipod, given the high degree of nanoelectronic development. Recent review of International Basic and General terms in metrology - VIM, now ISO Guide 99:2008, shows a new metrology tendency, whichmust be understood by all the scientific, industrial, and legal community in an ever-more globalized world.


The core themes of the body of work Antarctica refer to issues of freer international migration, displacement, habitat, environment, survival and cooperation. Drawing from the idealogical premise of the 1959 Antarctica Treaty, Anatrctica embodies the hope for a neutral peaceful land, free of conflict and dedicated to common goals for research. To visualise these themes Lucy Orta and her partner Jorge have created a multi-facted series of artworks (installation, sculpture, video, photography, drawing, public engagement artworks, digital platform, etc), that have been the focus of large scale installations that attract tens of thousands of visitors.

The Antarctica exhibition at the Hangar Bicocca, curated by Bartolomeo Pietromarchi, represented the first complete public showing of the artworks created by the artists as a result of their expedition in Antarctica in 2007. The exhibition was also an occasion for presenting other major works created over the previous five years, addressing social, environmental and humanitarian issues: mobility, population migration, climate and environmental crises, and human rights.


This paper describes an automatic quality control system that supervises through three CCD cameras the assembly of automobile airbag sensors. The main characteristics that can be detected are position, angle and geometric parameters of epoxy resin to fix the accelerator sensor. The system can inspect 12000 pieces/hour and now it is at full production in a multinational automobile component factory at Madrid.


LLC resonant converter is used to control laser output power in Nd:YAG laser. Zero voltage switching (ZVS) is implemented to minimize the switching loss which is adopting the LLC resonant converter. In the spot welding processing of metal thin films, the processing quality is decided by the laser beam output energy of single pulse. We decide to the 50 [J] as the single pulse laser beam energy. Laser output power is investigated and experimented by changing the output current. That current is controled by the charging voltage of capacitor. From those results, we obtained the maximum laser output of 58.2 [J] and the conversion efficiency of 2.52% at the discharge voltage of 620V and the discharge current of 861 [A] and the pulse repetition rate of 1 [Hz] at the charging capacitor of 12,000 [μF].


This paper is drawn from a mixed methods study, which examined the leadership practices of teachers in the Level Three Classroom Teachers program in Western Australia. Three archetypal characters, the Torch Bearer, Weary Juggler, and Heckler, are used to represent the diverse leadership experiences of these "expert" teachers and the extent to which they embraced or resisted policy constructions of teacher leadership. Narrative analysis and the construction of these representations provided the means of inserting teachers' voices and problematizing dominant discourses on teacher leadership in a way that invites policymakers to reconsider the larger narrative of teacher leadership, along with the personal dimension of leadership work.


In recent years,due to over-exploitation of resources,resulting in increasing prices of construction materials,coupled with people's increasing emphasis on the concept of recycling resources,it has great importance to eliminating road asphalt concrete recycling material recycling.However,in the course of transmission,we can only know the beginning of the end to send mixing drum inlet temperature of heating much,and can not actually grasp the actual temperature inside the mixing drum.Therefore,recycled materials are likely to be heated to high temperatures,resulting in aging and even carbonization,thereby affecting the quality of recycled asphalt concrete.In this study,recycled asphalt mixing plant asphalt concrete as research material,recycled material according to different aging conditions mainly microscopic differences and engineering nature to explore,study results showed that excessive preheat the recycled material would indeed cause the quality of recycled asphalt concrete is not good,especially the ability to resist water violations decreased a lot.


The aim of this thesis is to study galaxy observables including UV luminosity and disc sizes at high redshifts using the new semi-analytic galaxy formation model Meraxes. We present calculations of UV luminosities and treatments of dust extinction and Lyα absorption. We show that we successfully reproduce the observed UV luminosity functions (LFs) at z ∼ 5–10. We find that the faint-end slope of UV LFs remains steep below current detection limits until at least MUV ∼ −14 indicating a large number of undetected faint galaxies during the epoch of reionization (EoR). We find that these undetected galaxies contribute significantly to the reionization. For example, galaxies with luminosities in the range −17 < MUV < −13 emit more flux than the MUV < −17 galaxies at z > 7. These predictions will be tested by next generation telescopes including JWST. We find that model galaxies with MUV ≲ −14 are distributed around the empirical luminosity–SFR relation with 0.1–0.3 dex, and that this scatter may bias the luminosity–SFR conversion for galaxies with low SFR (< 0.01M⊙/yr). We also show that the mean luminosity–stellar mass relation and the mean luminosity–halo mass relation from the model are in good agreement with observations, and can be fitted using singular power laws as M∗ ∝ L UV and Mvir ∝ L UV respectively. These relations retain their form until at least MUV ∼ −14 and may break at fainter luminosities due to the hydrogen cooling limit in low-mass haloes. We show that galaxies with MUV ∼ −20 are hosted in dark matter haloes of mass Mvir∼1011.0±0.1M⊙ at z ∼ 6. This mass decreases linearly towards higher redshift. We find a size–luminosity relation of Re ∝ L UV , in good agreement with observations including the recently discovered luminous galaxy GN-z11. We also find that galaxy sizes can be an important observational probe for galaxy formation during the EoR, allowing us to discriminate between different star formation and feedback models.


The LM-EM algorithm has the advantage to calculate the emission probabilities needed for the reconstruction process on the fly, without the need of a pre-calculated system matrix. The reconstruction time for this algorithm strongly depends on the used backprojector and the available statistics. This algorithm when implemented in systems using monolithic crystals to detect gamma radiation allows one to extensively exploit the virtual pixilation feature, not available for systems based on pixilated crystals. In this work we present a backprojector for LM-EM, the TOR method, which achieves a tradeoff between computational efficiency and image quality. Its temporal subset algorithm optimization (LM-OS) has also been implemented in order to achieve real-time reconstructions. To evaluate the performances of LM-OS algorithm with the TOR method backprojector and only with one iteration on the datasets, studies based on the system spatial resolution, uniformity, and contrast coefficients were carried out and they were compared with those obtained with LM-EM and MLEM algorithms using twelve iteration. Finally, a study on reconstruction time using LM-OS has been performed with breast patients data.


In Argentina educational policies dealing with the effects of COVID-19 have encompassed the lockdown of schools in every compulsory educational level and the National Ministry of Education´s demands to all provinces to guarantee the continuation of schooling. This article examines, on the one hand, material conditions and time organisation of secondary school teachers´ telework at the beginning of the confinement. On the other hand, it explores teachers´ perceptions about their participation in the decision-making process that regulated their work, their views on the mental workload that the emergency and forced telework implied, and their social responsibility towards educational inclusion. To do so, it examines the results of an online survey applied to 678 secondary school teachers from the Metropolitan Area of Buenos Aires, which was carried out at the end of April and at the beginning of May. This piece evidences an increase of work time, in a context of teachers´ material inequalities and diverse institutional cultures (in terms of teachers´ participation, work climate and schools´ previous pedagogic use of TIC), which has impacted on teachers´ mental workload without significantly eroding their trust in school´s ability to educationally support their students.

Roof rats {Rattus rattus Linne, 1758) have been existant in the area covered by present-day Germany for almost 2 000 years. Excavations revealed remains dating back to the second Century (Lüttschwager 1968), to the 3rd-5th Century (Teichert 1985), and to the early middle ages (Reichstein 1974, 1987). Patterns of their distribution in Central Europe appear not to be hnked to natural conditions, such as climate and Vegetation, but rather to manmade conditions, which tend to change rapidly. Roof rats may suddenly be introduced by the transport of goods, and they may be extinguished locally when industrial Sites are abandoned or farms are modernized (Becker 1978). Pest control Opera-


In order to generate optical millimeter wave signals, two cascaded Mach-Zehnder modulators (MZMs) are utilized. The first MZM modulates electric signals in the form of single side-band. Optical single side-band (OSSB) approach is a method to overcome the fiber chromatic dispersion effect for long distance communications. Two OSSB channels' frequencies are then upgraded to 60 GHz band in the optical domain. RF power adjustment is critical to decrease unwanted harmonics' interference effect. Simulation model is examined for two 60 GHz sub-bands transmission. The study is done for a single mode fiber with attenuation of 0.1 dB/km, and chromatic dispersion factor of 16 ps/(nm·km). Results are presented and the performance of the suggested approach is discussed.


SCHARDOSIM, Mariane Giacomini. Confection of permeable tubular scaffolds of PLGA for nerve regeneration. Porto Alegre. 2012. Master. Graduation Program in Materials Engineering and Technology, PONTIFICAL CATHOLIC UNIVERSITY OF RIO GRANDE DO SUL. Peripheral nerve injury accident is a common type of lesion that can cause loss of mobility and decrease the quality of life. Despite advances in the biomedical area, there are few cases where there is complete functional recovery of a damaged nerve. The application of biodegradable polymers such as poly(lactide-co-glycolide) (PLGA), shows a viable alternative of treatment in peripheral nerves injuries for presenting mechanical strength, biocompatibility and controlled degradation, being also an excellent material for drug delivery. A PLGA scaffold should be porous with pore sizes on the order of micro-and nanometer, which offers the possibility to insert growth factors, promoting a constant release of these biological structures. The aim of this research is to produce porous scaffolds of PLGA. This was achieved by dissolving the polymer in chloroform, adding a porogenic compound. A titanium rod with 2mm in diameter was deeped in the suspension obtained and dried in a hood, obtaining a layer of PLGA / porogen agent on the surface of the rod. In sequence, the rod was immersed in a solution of PLGA with chloroform. After dried for 2 hours in a hood, the titanium rods were submerged in deionized water for 48 hours, during which the water was changed every 8 hours in order to remove the porogenic agent. After this process, the tubular structures formed were easily removed from the rods. Finally, the prepared tubes were divided into groups and treated with different concentrations of sodium hydroxide, to create pores in the order of nanometers, and subsequently vacuum dried for 48 hours. The structures obtained were characterized by XRD, FTIR, SEM and the in vitro degradation was monitored by GPC.


In this study, we draw on upper echelon theory and seek to begin answering the questions of how and why caring in top management team (TMT) underpins strategic adaptability. We argue that when these team members care for each other's inner needs, a generative space (which allows individuals to experience positivity and produce transformative outcomes) is nurtured. This generative space, in turn, helps to build a capacity to adapt to environmental jolts. The results of multisource data indicate lend support to our theorizing that caring among team members nurtures generativity, which in turn builds strategic adaptability. This research enriches our knowledge regarding the micro-relational foundations of strategic capabilities in general, and how relational processes underpin an organization's capacity to adapt to competitive environments.


Article aims to disclose the prospects of development of international space law, contains the main directions of its development, and explains its necessity.


Title of Thesis: THE INFLUENCE OF THE JESUITS ON T HE PASSION MUSIC OF ORLANDO DI LASSO Nicholas Dean Johnson, Master of Arts, 2006 Thesis Directed by: Professor Richard Wexler School of Music This study explores the four Passion settings of Orlan do di Lasso, composed between 1575 and 1582, which have largely been ignored by music sc holar . Scholars have recognized that a dramatic compositional shift occurr ed between the second and third settings, but have provided no cogent explanation fo r the change. Most reasons given revolve around the Council of Trent, which held it s final session in 1563. However, a consideration of the history and religious contexts of the works discloses other, possibly better explanations. I propose that the primary influence leading to Lasso's c mpositional shift was the liturgical reform initiated by his employer, Duke Wilhe lm V, and enforced by the Jesuit priest Walram Tumler. These reforms had a prof ound effect on all facets of worship in Bavaria, most notably music. Recognizing the infl uence of the Jesuits on Lasso's music makes it possible to understand the composer' s dramatic change in style. THE INFLUENCE OF THE JESUITS ON THE PASSION MUSIC OF ORLANDO DI LASSO


more than six decades after its initial publication, alfred kazin's A Walker in the City (1951) occupies a curious place in the canons of jewish-american and ethnic writing. Though still read in university courses and cited in discussions of the history and literature of jewish new York, kazin's memoir of growing up in the Brownsville section of Brooklyn during the 1920s and early '30s has increasingly been assigned the role of a representative cultural document whose value is more historical than literary. kazin was vocal in his opposition to this use of his memoir.2 Writing to his French publishers about their decision to release the book under the title Retour á Brooklyn [Return to Brooklyn], kazin noted that he was "very distressed" that the new title might encourage readers "to think of the book as just another sociological document."3 His concerns would prove well founded. A Walker in the City tells the familiar story of the coming of age of an immigrant family's first american-born son: his discovery of literature and, through it, the world beyond the "ghetto," and his attempts to make a new and better life for himself in that vague but radiantly imagined world. From this familiar plot, critics have extrapolated a no less familiar set of values, presenting the memoir as a conventional assimilation narrative told in the key of postwar nostalgia.4 according


Water-retention and fertilizer-retention (WRFR) was prepared by solution polymerization, and the properties of WRFR were studied. The optimum preparation conditions were as follows: cross-linking agent, montmorillonite and initiator were 0.05%, 15% and 0.45% as the monomer by weight, respectively; the reaction temperature was 75 °C, and the neutralization degree was 90%. The distilled water absorption rate of the prepared WRFR was 796 g/g. The water evaporation quantity of the prepared WRFR in 24 h at ambient temperature was less than 9%, and this value was increased to 99.72% the prepared WRFR was treated by water bath at 60 °C for 10 h. The water-retention rate was 57.4% while the prepared WRFR was centrifuged at 4000 rpm for 10 min, and the adsorption rate of 10.0 g/L urea solution was 500 g/g. After dynamically washed by 50 mL distilled water, the residual urea of the fertilizer was 31.78%, which prepared by using 0.1 g WRFR to adsorb 20% urea solution.


The exploitation of tin ore by Overseas Chinese is an important part of the development history of Southeast Asia.The activity covers ore exploitation,the spread of technology,cultural communication,economic development and social progress,constituting significant historical material for the study of communication between,and the development of,modern China and Southeast Asia.This paper systematically studies the historical background to this phenomenon,focusing on the spread and application of the technology involved.


For soft films with a thickness on the order of microns or nanometers, the long-range surface∕interface interaction can be sufficiently strong to induce their surface instability or even rupture. By using the bifurcation theory of elasticity, we here present a three-dimensional theoretical model to study the spontaneous surface instability of a soft elastic thin film supported by a rigid substrate. By accounting for the competition of van der Waals interaction energy with elastic strain energy and surface energy, we obtain the analytical solutions for the critical conditions of three-dimensional surface morphology instability. The effects of surface energy, thickness, and elastic properties of the film on the characteristic wavelength of surface wrinkling are examined. It is found that the characteristic wavelength of the deformation bifurcation mode depends on the film thickness via an exponential relation, with the power index in the range of 0.75–1.0, which mainly depends on the ratio between the surfa...


Mitochondria were isolated from the F1 Hybrid Rice-Shanyou 63 and the metabolic and thermogenic effect of Nd(III) (0, 8, 15, 20, 40, 60ug·L -1 ) was determined by the use of ampoule method at 30 o C. The thermogenic curves were used to calculate the rate constant (K1), the maximum heat production (Pm) and the total heat production (Q) of mitochondria during activity recovery phase after treatment with Nd(III). The result shows that low concentration Nd(III) stimulated metabolism in the mitochondria which was suppressed by high Nd (III) concentration treatments. The observed concentration-dependent effect of Nd (III) on mitochondrial metabolism is similar to plant growth response to rare earth elements. Based on these results, Nd (III) could have primarily interfered in mitochondrial metabolism which would subsequently affect plant growth.


Nowadays many students are weak in P.E They can't do what is required properly,and always get very low achievements.So it is the teachers' responsibility to teach them well.There exist aspects in their weakness.In general,there are big differences between their individual characters.This essay focuses on finding the causes and effects by doing lots of surveys among students,and finally gives some practical suggestions on how to improve the teaching toward such students.


The objective of this study is to design resolution-based programming languages that can reason properly in the presence of disjunctive or indefinite information. It has been known that this type of information causes serious computational difficulties for resolution-based languages. We first show that re-entry points of model elimination procedure can be used to compute disjunctive query answers (e.g., the answer$\{x/a,x/b\}$, given the program consisting of the single clause $p(a) p(b)$ and the query $\exists x p(x))$. We establish a completeness result of model elimination procedure for such query answers. We then consider three special cases of model elimination procedure, SEI, SEA, and MEI, in order to: (1) understand specific contributions of major inference mechanisms of model elimination separately, and (2) identify some intermediate forms of resolution which are powerful enough to realize, to some satisfactory extent, inference involving disjunction, yet restrictive enough to avoid the inefficiency of full first-order resolution procedures.
Our main results show that: (1) the class of case-free programs is the largest class of SEI-complete programs, where, intuitively, case-free programs are programs which do not require case analysis in computing query answers, (2) SEA is powerful enough to compute all definite query answers, including those that require case analysis, and (3) MEI can compute all indefinite as well as definite query answers as long as each case assumption is monadic, i.e., expressible in a single literal.
Among these special cases of model elimination, MEI is particularly interesting because it is only a minor modification of SLD, the basic inference procedure underlying most logic programming languages. More specifically, MEI does not require factoring or ancestor resolution, two costly operations generally necessary in full first-order resolution.


"The flipside of an error": The case of Amos or False Hopes by Anna Langfus

The current article is a preliminary sketch of the study of recurring motives found in the dramatic works of Anna Langfus. After a short presentation of the profile of the writer and the role of the theater in her life, we look into an unpublished play Amos ou les fausses espérances / Amos or False Hopes (1961). The concept of "patterns of transitivity", proposed by Jean-Pierre Richard in Onze études sur la poésie moderne / Eleven Studies on Modern Poetry, is guiding our reading of Langfus' play in this context.


This paper attempts to clarify the educational role of an ethnic church using the case of Filipino Newcomers. This study focuses especially on the generational differences between parents and children. Many studies indicate the influence of an ethnic church on the social integration of immigrants. However, there are few studies discussing ethnic religious associations in Japan. This study might offer a new insight into migration studies in Japan. The data that form the basis of this research are based on semi-structured interviews with the pastor of this church, Sunday school teachers, fifteen Filipina mothers, six Filipino teenagers, and participant observations in the church. The results can be summarized as follows. Firstly, the Sunday school plays the role of reducing the mothers' worries about their children's education by providing a place where children can study English. On the other hand, the youth group that is managed by young Filipinos plays the role of providing a place to confirm their ethnic roots and receive recognition. The youth group provides a place where they can meet friends with similar backgrounds and feel comfortable. Secondly, the Sunday school is constructed by the parents' needs, and the youth group is based on the young Filipinos' needs. Some parental expectations are inherited in the youth group, which prevents their children from falling into delinquency through mutual friendships. On the other hand, there is a gap between parental expectations and children' s needs. Parents wish to see their children acquire English ability in the Sunday school, while the youth group places importance on Tagalog rather than English. Young Filipinos who have emigrated to Japan during school age, feel comfortable speaking Tagalog. They therefore regard the youth group as a Tagalog speaking community. These young Filipinos, rather than their parents, teach Tagalog to the children who grow up in Japan. Finally, both the Sunday school and the youth group play the role of helping children to integrate into Japanese society and schools. However, this does not mean that they promote their assimilation into Japanese society. They need a place to confirm their ethnic roots and receive recognition in order to resist assimilation pressure from Japanese society.


Abstract : Results are given of experiments on the detection and study of oscillations developed in a beam and plasma produced as the result of their interaction. The experiments were conducted under conditions where the electron Langmuir frequency of the plasma, was less than the electron cyclotron frequency. The conditions of wave excitation in the beam and plasma, their frequency spectra, phase velocities, amplification factors, electrical field intensity, and absolute values and spectral distribution of excited oscillation power are determined. Experimental results from measurement of frequencies, amplification factors and phase velocities of excited oscillations in the plasma are in satisfactory agreement with calculated data. (Author)


ABSTRACT The economic crisis that hit European countries has been the object of various studies, aiming to understand how laypeople construct their opinions and guide their actions to deal with the difficulties stemming from the implementation of austerity measures. The present study analyses the responses given to an online survey by 630 Portuguese adults. Focusing on their support for possible government strategies to manage the crisis, it examines the changes which have occurred over time in their opinions, and compares them with opinions expressed in other European countries hit by the crisis. The main results suggest that support for strategies differs according to the attribution of responsibility for the crisis either to the people or to supranational institutions. In line with the findings from other countries, conformity to European Union demands is supported by higher class right-wingers, rationalization of the public sector by somewhat insecure centrists, and exit from the European Union by more vulnerable left- and right-wingers. Results also show a global decrease in support for the European project, which questions the way the EU deals with the problems of its member states as well as the ideals it pursues.


Network security refers to protecting the websites domains or servers from various forms of attack. Network security is important in every field of today's world such as military, government and even in our daily lives. Having the knowledge of how the attacks are executed we can better protect ourselves. The architecture of the network can be modified to prevent these attacks, many companies use firewall and various polices to protect themselves. Network security has a very vast field which was developed in stages and as of today, it is still in evolutionary stage. To understand the current research being done, one must understand its background and must have knowledge of the working of the internet, its vulnerabilities and the methods which can be used to initiate attacks on the system. Internet has become more and more widespread, in today's world internet is available everywhere in our house, in our work place, mobiles, cars everything is connected to the internet and if an unauthorized person is able to get access to this network he can not only spy on us but he can easily mess up our lives.


From the cover: "This book provides an introduction to the basic concepts and facilities of text-based interfaces. The major underlying theme is that in any system, the interface software can be identified as a distinct element separate from the task processing. The book illustrates how this separation can be achieved and how interface functions can be represented by general abstractions independent of the devices on which the system is to be implemented. Most chapters incorporate sets of discussion and programming exercises."


In December 2019, an outbreak of a novel zoonotic coronavirus began, called SARS-CoV-2 or COVID-19, which reached pandemic dimensions on March 11, 2020. By March 3, it had already entered República Argentina, while on March 9 the first case occurred in the Province of Rio Negro. In this province, 823 cases were identified with 41 deaths and 602 recovered cases by June 30, giving rise to successive intervention strategies to prevent its arrival in some places without viral circulation, to control outbreaks occurred and, when this objective was achieved, to avoid reintroduction. Among all measures, those related to non-pharmaceutical Interventions or NFI based on Primary Health Care and One Health with integrated participation among health agents of the First Level of Care, veterinary public health and medical areas of the Departments of Activities for the Area and Its Primary Health Care Centers and epidemiology services are a central, highly effective and essential strategy to cut the transmission chain and decrease the agent's reproductive capacity (R0) to a value <1. The activities carried out from the appearance of cases were described in the towns of El Bolsón, San Carlos de Bariloche, General Roca and Choele Choel in the Province of Rio Negro during 110 days of the pandemic.

2021-2022. 3%, 6%, Abstract The Sarangan Irrigation Area has a problem, namely that there is not enough water to meet irrigation water needs. Optimization techniques are needed based on these problems optimal water management efforts are required. This research aims to optimize irrigation water allocation to obtain maximum profit. The optimization technique used is a deterministic dynamic program. The optimization objective function is the maximum profit with the constraint functions in the form of land area and the availability of discharge. The cropping pattern follows the Global Planting Plan (RTTG) for 2021-2022. Based on the optimization results, it was found that the increase in planted area and profits in the first planting season was 3%, in the second planting season it was 6%, and in the third planting season it was 7%. This research can be useful for the relevant agencies to find out the optimal water supply that can produce maximum profit based on water availability in the Sarangan Irrigation Area.


Abstract All constructions are subject to the most compound loads and therefore a suitable effort hypothesis should be used for their calculation. For anisotropic materials, a hypothesis should be used to describe the properties of such materials. In the work have been shown the strength of the layers composite on the example of construction wood in a compound stress state. Wood composite is an orthotropic material. Wood is composed of alternating layers of soft wood and hard wood. Single layers are monotropic material. The use of a stress hypothesis, which describes the strength of an orthotropic material, requires will make an investigation. Studies is purposed to determine the tensile strength along and across the fibres. The compressive strengths along and across the fibres and the shear strength. Particularly the determination of shear strength requires special tooling so that in the case of flat samples in the measuring part it is possible to determine the shear stresses. Therefore, a research stand was designed and constructed. Known stress hypotheses for anisotropic materials have been analysed. The analysis showed that the strength of the wood composite could be described by the Tai-Wu stress hypothesis. Based on the results of the research, numerical calculations were performed. Calculations allowed determining the distribution of stresses in the sample measuring part. The results tests and numerical calculations have shown that obtaining a homogeneous stress (shear) condition for anisotropic materials is very difficult. Wood belongs to materials whose mechanical properties depend on many parameters, so the description of the effort of this material is a compound issue. Studies have shown that wood reinforcement by polymer saturation is best suited to the compressed loaded structures.


Alan Bennett is one of the most popular mainstream dramatists working in Britain today, his canon now a mainstay of regional and amateur theatre companies. Yet for a writer who was once compared to John Osborne as taking 'the moral temperature of the nation', his output is widely regarded as apolitical and, at worst, 'safe'. In the following article, Richard Scarr suggests that this viewpoint is misleading, and argues that Bennett is not only one of the most politically contentious playwrights in dominant theatre, but that the ideological viewpoints he has supported have changed as his career has progressed. Richard Scarr is an English graduate of the University of North London, and has recently completed an MA in Renaissance Studies at Queen Mary and Westfield College. He is currently researching a PhD on the rhetoric of Renaissance comedy, with particular emphasis on the double-entendre.


Aquaculture, as an enterprise, is a relatively recent matter of concern among American entrepreneurs. It is an undertaking that requires knowledgeable, venturesome and resourceful technologistscum-business managers to structure a practicable system of economic aquafood production utilizing the available resources from sunlight to market. The risks are numerous, and often ill-defined, but the potential rewards are great, and thus aquaculture has attracted bold and venturous investors even though in many recent cases the requisite knowledge and skills were lacking.

There is an attractive analogy often drawn between terrestrial and aquatic animal husbandry which may be appropriate only if a realistic recognition is made of the metaphorical nature of the comparison. It has become common to compare aquaculture with the poultry industry which has reached a highly sophisticated and complex state of development. No aquacultural candidate animal is yet as well understood as the chicken is, nor do we have command over the environment to a sufficient degree to enable the production of aquafoods in adequate sustained supply to justify a major investment in the vertically integrated system from feed to marketing that seems to be required.

We have yet to provide a high level of assurance that we can comnand a supply of vigorous seed for stocking, an appropriate feed for growing, control disease, predators and competitors or manage the environment so as to materially reduce the risks, and enhance the probability of a satisfactory return on investment.

These matters of biological and engineering importance are considered in the context of aquabusiness imperatives, and are judged as risks to the venture.


An axis-encircling large-orbit cusp electron beam can keep stable work in high power and high frequency gyrotrons traveling wave amplifiers (gyro-TWAs) at high efficiency. However, the CUSP magnetic field is difficult to obtain in engineering realization. A gradually-varying magnetic field produced by a solenoid magnet is obtained for the axis-encircling large-orbit cusp electron beam, which is designed for a Ka-band gyro-TWAs. And a magnetic cusp gun (MCG) is designed, which can work with low parameters spread at the beam voltage of 65kV and beam current of 5A. The calculated results show that the beam can be generated with average radius 1.1 mm, average beam pitch ratio $\alpha=\mathbf{1.0}$, and the axial magnetic field $\mathbf{B}_{\mathbf{z}\mathbf{0}}=\mathbf{0.641}\mathbf{T}$ is designed as the magnetic field in the interaction region. At the same time the spread of the transverse velocity and the longitudinal velocity are 2.3% and 4.3% respectively. The designed can be used for Ka-band gyro-TWAs.


In the last few years there has been a great interest in developing electronics at a molecular level (molecular electronics), e.g. to construct miniaturized electric circuits that would be much smaller than the corresponding micron-scale digital logic circuits fabricated on conventional solid-state semiconductor chips. An alternative possibility to the use of electron fluxes as a means for information processing (electronics) is that of using optical beams (photonics), but up until now scarce attention has been devoted to the possibility of developing photonics at the molecular level. In this paper we review some recent achievements in the design and construction of molecular-level systems that are capable of transferring, switching, collecting, storing, and elaborating light signals. The combination of molecular photonics with chemionics can lead to a wealth of molecular-level devices capable of information processing.


The experiment was carried out with pond culture under rain-proof shelter condition to investigate the release of mineral elements in soil and the absorption of mineral elements by upland rice plants.The results indicated that soil moisture influenced remarkably N,P and K content in soil and nutrients absorption by plants.With the increase of soil moisture,the NO3——N content in soil was markedly decreased and the NH4+-N content was increased;The content of P changed with low-high-high curve under low soil moisture,and with high-low-high curve under high soil moisture;The content of K in the early tillering stage changed with low-high tendency under different soil moisture treatments,and its content in 65% and 100% treatments was higher than others during the mid and late tillering stage.As for the nutrients absorption by plants,the N content in upland rice was decreased continuously under 100% soil moisture,the P content assumed the "U" curve under 65% and 75% treatments,while the N,P and K content in upland rice assumed the "W" curve under other moisture treatments.With the increase of soil moisture,the total absorption quantity of N,P and K in upland rice was all added.


This commentary offers a critical assessment of the molecular age of biological systematics and deals with certain basic tendencies that seem to indicate a new phase of the discipline. These tendencies have engen dered a prevalent one-dimensional thought that un dermines the very foundation of systematics. This new phase has produced an advanced state of conformity with its consequent stifling of criticism, restricting the legitimization of problems and methods, research pri orities, and last but not least, job opportunities and modes of organization of institutions. Biological systematics is a multidimensional scien tific discipline that describes, names, classifies, and de termines relationships among the Earth's biota. It ac complishes these deeply interdependent tasks through surveys, inventories, collections, description of species, phylogenetic reconstruction, hierarchical classifica tions, monographing, and application of rules of no menclature. All these activities, except phylogenetic re construction, are encompassed by the sub-discipline named taxonomy (Wilson 2003). Systematics provides a reference system for the whole of biology and therefore can be seen as both the most basic and the most wide-ranging area of biology. It is the most basic because organisms cannot be dis cussed or treated in a scientific way until some clas sification has been achieved to recognize them and give them names. It is the most wide-ranging because it gathers together and summarizes everything that is known about the characteristics of organisms, whether geographical, morphological, physiological, genetic, ecological, or molecular. Beneath the fundamental scientific importance of systematics for biology, lies a growing urgency. The roughly 1.7 million species known to science to date probably represent at best fewer than 15% of the actual number. Of the named species, it is estimated that less than 1% have been studied beyond the essentials of geographic location, habitat preference, and diagnostic morphology. At the same time, thousands of species (known and unknown) are threatened by imminent ex tinction (Raven 2002). Were we required to characterize the current age of systematics by any single epithet, we should be tempt ed to call it "the molecular age." Molecular data have provided a new class of features that allow not only phybgenetic reconstruction of closely related taxa, but also broad scale comparisons across all organisms from bacteria to mammals and plants. Unquestionably, we are witnessing an extraordinary time when molec ular systematics is generating an unprecedented rev olution within the discipline (Daly et al. 2001). Despite the tremendous advances, there are pro found perils in the molecular age of systematics: 1. An unbalanced emphasis favoring phylogenetic recon struction based on molecular data at the expense of taxonomy; 2. A narrow research program that ignores many aspects of organismal biology and fragments systematics; 3. An unbalanced education of the new generation of systematists; 4. A depreciation of natural science collections as part of a broader trend away from organismal biology; 5. A slowdown of taxonomic work that will affect the conservation of biodiversity; and 6. An intellectual climate that marginalizes those with different views. I will briefly elaborate on these perils and their consequences. An Unbalanced Emphasis. Taxonomy was once the proud flagship of the natural sciences. Charles Darwin, the founder of the theory of natural selection, working in Cirripedia (barnacles) in the 19th century and Willi Hennig, the founder of modern phylogenetic recon struction, working in Diptera (flies) in the 20th century, were both practicing taxonomists. However, in the last 30 years taxonomy has seen a gradual loss of credibil ity among fellow scientists. This image problem is based on misconceptions of how taxonomy works. The view that taxonomy is a purely descriptive branch of knowledge that consists only of observations (Anony mous 2004) is a clear example of these misconceptions. In fact, taxonomy is a scientific discipline that requires description, but also theoretical, empirical and episte mological rigor, a hypothesis-driven approach, and field and lab expertise (Stuessy 1990; Carvalho et al. 2005). Furthermore, classification systems are hypotheses. A taxon, the basic unit of taxonomy, is a classification system and as such is a scientific hypothesis about or der in nature (Thiele and Yeates 2002). Like every sci entific hypothesis, a taxon goes beyond the evidence (observations) for which it purports to account. That is, a taxon has greater scientific content (e.g., predictive capability and explanatory power) than the empirical 217


I read with interest the article by Dr. Yadarola et al entitled "Perfluorocarbon liquid vitreous delamination and wideangle viewing system in the management of complicated diabetic retinal detachment" (1). The authors used perfluorocarbon liquid (PFCL) and a wide-angle viewing system (WAVS) to evaluate their efficacy on tractional and combined tractional/rhegmatogenous retinal detachment (RD) secondary to proliferative diabetic retinopathy (PDR). This technique resulted in "less bleeding during surgery, a better identification of intraocular structures, faster retinal reattachment, subretinal fluid reabsorption, and easier dissection of fibrovascular membranes." The authors conclude that PFCL and WAVS appear to reduce intraoperative complication rates in the management of complicated cases of tractional and combined tractional/rhegmatogenous RD secondary to PDR. The authors, however, failed to mention that the technique has been previously published under the name of en bloc perfluorodissection (2, 3). This technique was introduced at the 2006 Joint Meeting of the American Society of Retinal Specialists (24th annual meeting)–European Vitreoretinal Society (6th annual meeting), Cannes, France, September 9–13, 2006, and presented since at several meetings in South America, Europe, the United States, and Hong Kong. I agree with the advantages of this technique. I have used en bloc perfluorodissection (EBPD) for complex RD associated with several vitreoretinal conditions including PDR and uveitis. En bloc perfluorodissection using PFCL in limited amount (mean: 4 mL in our studies) may be a useful technique during vitrectomy in eyes with complex RD. Other advantages of EBPD include retinal stability at the time of vitreous removal, better visualization of vitreous and intraocular structures, rapid retinal reattachment, less blood in the vitreous cavity, subretinal fluid resolution, blood confinement, and easier dissection of epiretinal membranes, as stated in my previous reports (2, 3). In recent years, our EBPD technique has evolved, and most of our cases are performed with sutureless smallgauge vitrectomy (4) and preoperative intravitreal bevacizumab (Avastin®, Genentech Inc., San Francisco, CA) in PDR (5). I believe that rapid advances in vitreoretinal techniques, instrumentation, and pharmacology have allowed us to improve our surgical results and decrease the rate of complications.


A dramatic rise in the incidence of obesity in the U.S. has accelerated the search for interventions that may impact this epidemic. One recently recognized target for such intervention is adipose tissue, which secretes a variety of bioactive substances including prostaglandins. Prostaglandin E2 (PGE2) has been shown to decrease lipolysis in adipocytes, but limited studies have explored alternative mechanisms by which PGE2 might impact obesity, such as adipogenesis or lipogenesis. Studies conducted on ApcMin/+ mice indicated that selective inhibition of the cyclooxygenase (COX)-2 enzyme led to significant reductions in fatty acid synthase (FAS) activity in adipose tissue suggesting lipogenic effects of PGE2. To further investigate whether these lipid mediators directly regulate lipogenesis, we used 3T3-L1 adipocytes to determine the impact of eicosapentaenoic acid (EPA) and celecoxib on PGE2 formation and FAS used as a lipogenic marker. Both arachidonic acid (AA) and EPA dose-dependently increased PGE secretion from adipocytes. AA was expectedly more potent and exhibiting at 150 uM dose a 5-fold increase in PGE2 secretion over EPA. Despite higher secretion of PGE by EPA and AA compared to control, neither PUFA significantly altered FAS activity. By contrast both AA and EPA significantly decreased FAS mRNA levels. Addition of celecoxib, a selective COX-2 inhibitor, significantly decreased PGE2 secretion (p < 0.05) versus control, and also significantly decreased FAS activity (p < 0.05). Unexpectedly, the combination of exogenous PGE2 and celecoxib further decreased the FAS activity compared to PGE2 alone or untreated controls. In conclusion, EPA-mediated inhibition of AA metabolism did not significantly alter FAS activity while both AA and EPA significantly decreased FAS mRNA expression. COX-2 inhibition significantly decreased PGE2 production resulting in a decrease in FAS activity and expression that was not reversed with the addition of exogenous PGE2, suggesting an additional mechanism that is independent of COX-2.

The paper studies the ecosystem of the Eastern Sivash in the context of natural and anthropogenic influence. The data collected during the expedition of the Azov-Black Sea Branch of the FSBSI "VNIRO" conducted in early summer 2020 were used as original empirical evidence. Specific features of hydrological and hydrochemical conditions, as well as species composition, distribution, and abundance of ichthyoplankton were indicated. It was shown that the values of pH, nitrates, nitrites, and phosphates did not exceed MPCs established for fishery water bodies within the entire water area under study; the range of dissolved oxygen content was wide: 3.63–9.13 mg/dm3 . By comparison of the environmental status of the biocoenoses during early summer 2020 with the data collected during a similar survey in 2019, it was found that the water temperature at site 4 is lower by 1.9–2.7 °C. Further salinization of the Sivash was recorded: the lowest salinity in 2019 ranged within 32–38 ‰ and the highest one ranged within 83–86 ‰; in 2020, these values were 36–43 ‰ and 91–97 ‰, respectively. In terms of spatial distribution, the range of the increase in salinity was 4.36–16.69 ‰, with the highest value being recorded at site 2 (11.51–16.69 ‰) and the eastern part of site 3 (13.22 ‰). To a lesser extent (by 4.36–6.26 ‰), an increase in salinity was recorded at site 4 and the western part (5.27 ‰) of site 3. The results of plankton net surveys showed that ichthyoplankton was represented almost exclusively by larvae of big-scale send smelt, which had the densest distribution at site 1 at a salinity of 89 ‰, and on the border between sites 2 and 3 at a salinity of 74 ‰. The upper limit of salinity at which this fish reproduction is possible lies within the range 75–90 ‰. The absence of so-iuy mullet eggs and juveniles at a salinity higher than 32–36 ‰ in May – June of 2019–2020 during the peak of so-iuy mullet spawning does not provide a reason to include the Sivash Bay among the Azov Sea areas important for reproduction of this fish species


The enzymatic histochemical localization of aldehyde oxidase in the rat liver lobule was investigated by use of a tissue protectant, polyvinyl alcohol, with tetra-nitro BT as the final electron acceptor. This method demonstrated the presence of aldehyde oxidase activity in the cytoplasm of liver cells. Distribution of aldehyde oxidase activity in the liver was uneven, being seen mainly in the pericentral rather than the periportal area as with xanthine oxidase. The reaction was not inhibited by TEI-6720 but was markedly inhibited by benzamidine. Results were consistent with those of immunohistochemical localization studies of this enzyme.


Founded on clientelism, Philippine politics was crafted to pass a single political corridor, none other than the formation of clans and dynasties more powerful than political parties and ideologies. In a patron-client relationship, the exchanges of favors transcend generations of voters and politicians laying the foundations for perpetual indebtedness. It is in this endless stream of favors —sought and gained— that the politicians and the masses, form a reservoir of dynastic bonds and obligations. Competition, as an essential feature of democracy, manifests itself in granted favors and welfare provisions among power-wielders, transforming the elections into a dole-out contest for local elites. Political kindness breeds an enduring image of good statesmanship and public service. Through interviews, this qualitative study seeks to create a solid understanding of political participation in Aklan's political environment. The data were collected from a congressman, a vice governor, board members, mayors, and key informants. The interview transcripts were coded and subjected to analysis in order to learn more about the nature and customs of political engagement in Aklan. There were twenty (21) responders in total for the study. Finally, this research proposes the different forms of political dynasties and their distinct characteristics. It recommends a cordial reception of all forms of political dynasties except the failed dynasty and argues that prohibiting the appearance of a political dynasty through the passing of the Anti-Dynasty Bill (ADB) is unjust, inhuman, and undemocratic.


Many communities in the Rivers State, Nigeria, are complaining about pollution problems due to waste discharges from industries located in their neighbourhood. Such incessant complaints indicate that effluents are not given standard treatment before their discharge into the environment. This study examined the quality of effluents collected from 6 randomly selected industries in the Rivers State and corroborated results obtained with those of questionnaires circulated in the communities where these industries are situated. Results confirms the observations of the communities that wastes are not properly treated before being discharged into their environment; this has greatly affected their health, water sources, marine life, vegetation and generally the environment.


Water jet machining (WJM) is an advanced promising technology, which can be used for cutting either metals or other nonmetallic materials like glass reinforced composites, ceramics or even glass plates [1]. This technology, or abrasive water jet machining as its modification, is advantageously used particularly for cutting a variety of difficult-to-machine materials. Since water jet machining systems are quite expensive, new methodologies are being developed to enable to use advantages of water jet machining in small and medium enterprises [2]. Surface and kerf quality after water jet machining always has to be evaluated for specific applications from the point of view of both material and technological parameters, because existing knowledge about water-jet cutting and machining is still ambiguous [3]. WJM is usually connected with surface unevenness, with typical texture marks called striations [4], whose character depends on water jet parameters. Generally, striations arise for three reasons, namely the nature of the step formation inherent to a jet cutting process, the dynamic characteristics of the water jet, and the vibration of the machining system [5]. As an example, in case of abrasive WJM, formation of striations and surface quality depends on distribution of particles in the water jet [6]. Surface quality after WJM and kerf parameters are strongly affected by nozzle diameter and also by number of waves in water flow [1].


This paper presents a novel amplitude modulator concept for envelope tracking power amplifiers, which provides maximum efficiency in the lower output voltage ranges, thus nicely matching the probability density function of modern high-peak-to-average-power baseband signals. It can easily handle modulation bandwidths in excess of 300MHz. Furthermore, it operates purely in switch mode, unleashing great potential for overall efficiency. A first hardware implementation reaches around 60 % conversion efficiency and over 84 % when the output voltage is at its minimum value.


When the formula for calculating the RPMT tariff does not have a standard calculation technique, the implementation of the calculation of the RPMT tariff between one area and another is different. Therefore, it is necessary to do a theoretical and empirical study to find the ideal RPMT calculation formula according to the Constitutional Court Decision Number 46 / PUU-XII / 2014. The results of the study show that the ideal pattern of RPMT calculation is that calculations based on Article 151 of the PDRD Law as it is reinforced by the Court of Constitution through Decision Number 46 / PUU-XII / 2014 which have canceled the Explanation of Article 124 of Law No. 28 of 2009 on the grounds that the imposition of a levy tariff that provides a maximum limit of NJOP without accompanied by a clear calculation system does not provide legal certainty that will cause injustice in its application. So the Central Government must immediately compile and discuss the Draft of Ministerial Regulation on Implementation and Retribution.


PURPOSE: To make filling density uniform, improve reproducibility of quality, and enable filling of absorbent having very different grain diameters, by introducing absorbent suspending in eluate into a column, and performing pressure filtration. CONSTITUTION: Absorbent suspension is maintained in the state of suspension in a vessel 1 by a stirring equipment 2, and introduced into a column 10 by a pump 6, through a valve 4 and a conduit tube 8. The density of the suspension is adjusted by opening a valve 4 and mixing eluate from a vessel 3. The suspension is preferably introduced into the column 10, under the pressure up to 900 bar. The operation pressure of the pressure filtration is measured by using a pressure gauge 7. The absorbent gathers in the column 10 on a disk annealed on the lower end. The eluate returns to the vessel 1 and/or the vessel 3 through valves 11 and 9. By the filling method which is continuous and capable of atomization, uniform filling density is realized, and quality of column filling has high reproducibility. COPYRIGHT: (C)1993,JPO

The abandoned phosphogypsum can be processed into gypsum embedded filler with certain specifications by low-cost harm-reduced treatment. Gypsum embedded filler cast-in-place concrete hollow floor is on the basis of bidirectional bibbed slab floor or composite open-web plate frame structure. Details of these two floor systems and their structural forms,configurations,characteristics and their applications are introduced in this paper. Compared with conventional slab system,gypsum embedded filler cast-in-place concrete hollow floor has distinct advantages in terms of function,structure height,cost,and sound effects in the large column grid structure. The gypsum embedded filler cast-in-place concrete hollow floor can be widely used.
