Today's world is rapidly moving towards digitization. In this context, protecting and safeguarding the digital resources is very crucial for a large organization or a country. Digital resources are attacked and virtually brought down using malware. One of the strategies to defend against malware is searching for a pattern inside them. These patterns become the signature for a malware and they are deployed into a security system for detection. But the traditional signature generation techniques fail against polymorphic malware, which change their form after every infection. In this paper, we propose a defense system which uses, Logistic regression with Anova F-Test and snort IDS to thwart these polymorphic malware. Logistic regression with Anova F-Test has achieved 97.7% accuracy.


Knowledge‐based systems, especially so‐called expert systems, which replicate the problem‐solving or decision‐making capabilities of human experts in specific areas, have recently gained considerable widespread interest. The advent of such systems emphasizes the critical role of employee competence, skills, knowledge and experience in an organization. This paper presents the salient features of knowledge‐based computing systems in modern office environments. In particular, I consider topics related to critiquing consultation systems and the possibilities of re‐using knowledge bases for training. The paper also discusses possible consequences, benefits, problems and other important issues in the area.


We characterize a 1/spl times/32 element metal-semiconductor-metal photodetector (MSM-PD) array utilized for optoelectronic mixing in an incoherent, amplitude-modulated laser detection and ranging (LADAR) system. The MSM-PDs that make up the one-dimensional array internally detect and down-convert light signals that are amplitude modulated at ultrahigh frequency (UHF). Range information is contained in the low-frequency mixing product derived by mixing a reference UHF chirp with a detected, time-delayed UHF chirp. When utilized in the LADAR system, the MSM-PDs eliminate the need for wideband transimpedance amplifiers in the LADAR receiver. This, in turn, reduces both the cost and complexity of the system. The breadboard LADAR architecture and components are described, and fundamental measurements and imagery taken from the LADAR, using these unique MSM-PDs, are also presented.

The complete solutions of the Schrodinger equation for a particle with time-dependent mass moving in a time-dependent linear potential are presented. One solution is based on the wave function of the plane wave, and the other is in the form of the Airy function. A comparison is made between the present solution and former ones to show the completeness of the present solution.


A series of new benzyloxy-functionalized 1,3-propanedithiolate (PDT)-type model complexes (A and 1–7) have been synthesized and structurally characterized. The benzyloxy-functionalized all-carbonyl complex [(μ-SCH2)2CH(OCH2Ph)]Fe2(CO)6 (A) can be prepared by condensation reaction of 2-benzyloxy-1,3-dibromopropane with the in situ generated (μ-LiS)2Fe2(CO)6, whereas it reacts with the in situ formed N-heterocyclic carbene 1-mesityl-3-methylimidazol-2-ylidene (IMes/Me) to give the corresponding carbene monosubstituted complex [(μ-SCH2)2CH(OCH2Ph)]Fe2(CO)5(IMes/Me) (1). The PMe3-monosubstituted complex [(μ-SCH2)2CH(OCH2Ph)]Fe2(CO)5(PMe3) (2) can be prepared by substitution of the CO ligand in parent complex A with 1 equiv of PMe3 in the presence of Me3NO·2H2O, whereas PPh3-monosubstituted and PPh3-disubstituted complexes [(μ-SCH2)2CH(OCH2Ph)]Fe2(CO)5(PPh3) (3) and [(μ-SCH2)2CH(OCH2Ph)]Fe2(CO)4(PPh3)2 (4) are prepared by reaction of A with 2 equiv of PPh3 under similar conditions. While the PPh3-disubstituted...

Highway agencies spend significant amounts of money and time in coring and in-situ testing of flexible pavements for quality management. The quality of the asphalt concrete pavement is assessed through field inspection, thickness and density measurement. Unfortunately, these parameters (except thickness) are not directly related to those used in design. To implement a mechanistic pavement design procedure successfully, or to develop realistic performance-based specifications, the modulus of laid-down asphalt concrete pavements is needed. As a results, more quantitative feedback about the pavement structure may be provided to the laboratory and design engineers. Seismic nondestructive testing methods can potentially offer an efficient, economical, reliable, and repeatable way of measuring modulus of asphalt concrete pavement layers. In addition, seismic methods for determining the modulus of asphalt concrete layers are discussed. A preliminary protocol for quality management of asphalt concrete pavements based on seismic methods is included. Issues yet to be resolved are discussed. A case study is also included to demonstrate the potential application of the methods in real-life projects.


The properties in the spin-bag mechanism of hige Tc superconductivity are studied in the SDW background. It is found that if the Coulomb repulsive potential is much smaller than the valence-band width and is not beyond a particular range determined by the bag energy, two doped holes can be pairing via sharing a common bag. The transition temperature has a maximum value of the order 200 K for reasonable parameters but is independent of doping concentration. In addition, the ratio of the energy gap to Tc is found to be the same as the BCS value. Finally, the specific heat jump at the transition temperature, the coherence length and the upper critical field are roughly estimated.


This paper deals with the control strategy for the double boost converter in power factor correction (PFC) application, working in continuous conduction mode (CCM). This converter is based on the classic boost converter split into two parallel modules of power processing; each one of these modules process half of the nominal power of the converter. Technical literature concerning this converter does not analyze in detail some very important control aspects and it seems that it is still lacking a general control strategy for such converter. This subject is developed in the present paper. This is done by converter modeling based upon the PWM switch model. The model obtained, verified by simulations, points to a multivariable control system, since the converter output voltages and the control variables (duty cycle of the two active switches) are strongly coupled. The dynamic uncoupling technique is applied in order to overcome this undesirable characteristic and to design the voltage and current compensation loops. Each module of power processing has a current mode controlled PFC circuit with a current-regulation inner loop and a voltage-regulation outer loop and the dynamic uncoupling is performed over the former. Numerical simulation results of the behavior of the double-boost converter for power factor correction application are presented.


The dissolutions containing Co(II) in a Tris-HCl medium and in the presence of perchlorate of 5,5-dimethyl-1,3-cyclohexanodione dithiosemicarbazone (DYDT-HClO4) produce a prewave that has been studied by means of classical polarography (DC) and differencial pulse polarography (DPP). The catalytic nature of the prewave has been established and the possible electrode mechanism proposed. The analytical possibilities of the mentioned prewave have also been analyzed in order to determine the DYDT, Hg(II) and Ag(I).


The Valsalva maneuver is described as an expiratory effort against a closed glottis or airway. It leads to elevation of retinal venous pressure and may result in retinal hemorrhage. A fifty two- year-old man presented with an acute reduction of central visual acuity in his right eye which occurred after considerable straining at stool. Detailed past medical history revealed that he suffered from chronic constipation and hypertension. There were one disc sized subhyaloid hemorrhage and three small intraretinal hemorrhages around the fovea at the dilated fundus examination. After three months of follow-up without any treatment, the retinal hemorrhages resolved without any sequelae. Here we report a patient with sudden visual loss and retinal hemorrhage.


Odd‐chain fatty acids (OcFAs) and their derivatives have attracted much attention due to their beneficial physiological effects and their potential to be alternatives to advanced fuels. However, cells naturally produce even‐chain fatty acids (EcFAs) with negligible OcFAs. In the process of biosynthesis of fatty acids (FAs), the acetyl‐CoA serves as the starter unit for EcFAs, and propionyl‐CoA works as the starter unit for OcFAs. The lack of sufficient propionyl‐CoA, the precursor, is usually regarded as the main restriction for large‐scale bioproduction of OcFAs. In recent years, synthetic biology strategies have been used to modify several microorganisms to produce more propionyl‐CoA that would enable an efficient biosynthesis of OcFAs. This review discusses several reported and potential metabolic pathways for propionyl‐CoA biosynthesis, followed by advances in engineering several cell factories for OcFAs production. Finally, trends and challenges of synthetic biology driven OcFAs production are discussed.


Isomerization of n-pentane was carried out over Pt-containing zeolite catalyst with a flow-type reaction apparatus under atmosphere. The typical reaction conditions were 230--300 C, 1 atm, H{sub 2}/n-C{sub 5}H{sub 12} = 9/1 (mole ratio), W/F 10.0 g h/mol. Thermodynamic equilibrium conversion of about 70% at 270 C could be reached on Pt/HZSM-5 (supported catalyst), Pt-hybrid (a physical mixture of Pt/SiO{sub 2} and HZSM-5 powders) catalysts. The isomerization selectivity was higher for Pt-hybrid catalyst than for Pt/HZSM-5. Pt-hybrid catalyst showed higher isomerization activity over wider temperature and pressure ranges than did Pt/HZSM-5. The effect of spilled-over H is considered to play an important role in the regeneration of Broensted acid site and the stabilization of an i-C{sub 5}{sup +} intermediate. A reasonable reaction mechanism is proposed.


Silver(I) nitrate and ethylenethiourea ( etu) in 1 : 4 stochiometry have been reported [1]. Coordination compounds of A and B as silver(I) nitrite with etu and silver(I) nitrite with N,N' -diethylthiourea ( detu) respectively, have never been done. The purposes of this study are to synthesize and characterize coordination compounds of A and B. Synthesis coordination compound of A with 1 : 4, while B with 1 : 2 stoichiometry. Both of coordination compounds are conducted directly in acetonitrile. Compounds obtained are characterized by melting point, electrical conductivity measurement, SEM-EDX , qualitative nitrite test, free energy calculation and structures prediction using Spartan'14 v1.1.0 . Coordination compounds of A and B are colourless needle and prism crystals; have melting point of 189°C and 103-105°C; free energy of -289,2567 and -1182.8101 kJ/mol respectively. Electrical conductivity measurement and qualitative nitrite test show that the obtained compound of A is an ionic and B is a molecular one. EDX analysis gives empirical formula prediction of two coordination compound A is C 12 H 24 AgN 9 O 2 S 4  and  B is C 15 H 36 AgN 7 O 2 S 3 .


We present an interest management technique that organizes the shared state of a virtual environment into domains and sub-domains. To specify users' interests, we have partially adopted the general aura-nimbus model. It has been generalized beyond its original spatial use to allow users to express their interests explicitly without relying on their spatial characteristics only.


A provider of the mobile communication program obtains the public key generated on the basis of a unique terminal identification number (IMEI) unique to an SDR terminal by a key generation algorithm, registers the generated public key in a key registration server, encrypts a mobile communication program with the public key, and distributes the encrypted program. The SDR terminal generates the private key on the basis of the unique terminal identification number (IMEI) by the key generation algorithm, decrypts the encrypted program downloaded from a server with the generated private key, and installs and operates the decrypted program. Since the mobile communication program is encrypted, although a third person tries to install an illegal copy program in an SDR terminal, the decryption is impossible, and the installation becomes impossible. In addition, it is possible to prevent ill-intentioned corruption and illegal reuse of an illegal copy program by the third person.


Abstract The South African journey towards transformation and the reasons why it was necessary suggest that vigilance about professional competence needs to be continuous. Educators have a responsibility to prepare graduates to meet practice challenges on a variety of fronts within the world arena, where constant change in expectations and demands is ensured. An ongoing attempt to prepare students to meet the professional competence standards and also enable them to become change agents, both personally and in a public context, is illustrated with reference to the undergraduate programme at the University of Cape Town.


A GIS based noise assessment was carried out to study the noise pollution scenario of Guwahati city at various locations, i.e. commercial zones, residential zones and silence zones (educational institutions and hospitals and nursing homes). Sound Level Meter (SLM) was used for assessment of noise levels and noise mapping was done using Geographic Information System (GIS) technique. From the study, it was observed that noise environment of the Guwahati city is deteriorating and unsafe in various locations for human and it exceeds the noise standards suggested by the Central Pollution Control Board (CPCB) and Bureau of Indian Standards (BIS). This study also highlighted the noise polluted and vulnerable areas through the diurnal noise mapping. It was also observed from the study that, places with high traffic congestion, narrow roads, heavy constructional activities and poor traffic management areas are more vulnerable to high noise levels. Some of the educational institutions, hospitals and nursing homes are also in the grip of high noisy environment. Highest noise levels ranging between 80–90 dB (A) recorded in commercial locations, 65–75 dB (A) in residential areas, 65–75 dB(A) in silence zone in the city.

On 1 November 1951 Norsel sailed from Göteborg on her third voyage to Maudheim; this time to evacuate the expedition. On board were the personnel and two aircraft of a Swedish Air Force unit. Air reconnaissance had been carried out in the expedition's first season by a British R.A.F. Flight. In the second season a Norwegian commercial flying unit had done some photography, and in the final season it was the turn of the Swedes to provide these services. In preparation for this the writer, who commanded the unit, had accompanied Norsel on her second voyage, and had thus been able to study the area, and discuss plans with members of the expedition.


The influence of alternating electric field (AC) in the structure and dynamics of giant unilamellar vesicles (GUVs) comprised of 1,2-dilauroyl-sn-glycero-3-phosphatidylcholine (DLPC) is reported. The investigations were conducted by using optical fluorescence microscopy as the method of analysis. The lipid membrane of the DLPC GUVs at the fluid phase can be deformed and they migrate towards the electrodes under AC electric field. Nevertheless, membrane disruption or vesicle fusion was never noticed. The addition of concentrated glucose solution influences the osmotic pressure of the system leading to the formation of filaments at the outer region of the GUVs. These long flexible cylinders do not retract spontaneously. However, the application of AC electric field (20 V/mm, 20 Hz) enables the filaments to be retracted back to the GUVs membrane at a calculated speed of 0.18 μm.s-1


The effects of the coating thickness on the delamination or fracture behavior of thermal barrier coatings (TBCs) were investigated through the cyclic furnace thermal fatigue (CFTF) and thermal shock (TS) tests. The TBCs were prepared using a NiCrAlY bond coat and an yttria-stabilized zirconia top coat, which were formed using the air plasma spray (APS) process. The thicknesses of the top coat were 200 and 400 μm, and those of the bond coat were 100 and 200 μm. TBC samples with a thickness ratio of 2:1 in the top and bond coats were employed in the CFTF and TS tests. After CFTF for 1429 cycles, the interface microstructure of the relatively thick TBC was in a sound condition without any cracking or delamination; however, the relatively thin TBC was delaminated near the interface between the top and bond coats after 721 cycles. In the TS, the TBCs were fully delaminated (> 50%) after 140 and 194 cycles for thicknesses of 200 and 400 μm in the top coat, respectively. These observations allow us to control the thickness of TBC prepared using the APS process, and the thicker TBC is more efficient in improving thermal durability in the cyclic thermal exposure and thermal shock environments. © 2014 The Authors.

External beam radiotherapy is one of the main methods of cancer treatment in curative and palliative oncology. It aims at precise delivery of high dose to a target volume, which is performed in a series of defined fractions by a linear accelerator. To ensure the effectiveness of the therapy and the safety of the patient, high reproducibility of the patient position is mandatory. In this paper, we review patient positioning techniques and compare their technical principle, system components, application in workflow, general advantages and drawbacks. Furthermore, we explore future potential for the implementation of digital tools.


The theoretical part of my diploma deals with health problems and types of sports injuries of primary school and PE teachers. The diseases and work related injuries that are common among people working in education are also described, and so are some statistical information connected to the topic.
In the second, empirical part, I wanted to find out, which health problems were most common among teachers and if these problems were in any way connected to the occupation. I wanted to find out how many times a year primary and PE teachers visited health institutions, what kind of doctors they most often visited and what was the connection between the visits and the duration of the school year. What was also important for the research, was whether teachers took good care of their own health and whether they were enough physically active in their free time. A part of my research was also to find out what types of sports injuries were most common among primary and PE teachers and whether or not the teachers were pleased with their working environment. I got the results by using a questionnaire. The inquiry was anonymous and the sample covered 66 teachers from primary schools in Notranjsko-kraska region in Slovenia.
I found out that the most common health problems among primary and PE teachers are allergies and spine and joints injuries. In my opinion these problems are not occupation-related, since they are common also among people outside this profession. Teachers go to the doctor's approximately two times a year. Most of these visits are visits to dentists, family doctors or gynaecologists and are not directly related to the duration of the school year. The teachers who took part in my research and are mostly non-smokers are satisfied with their own health, but believe that they could take better care of their health, even though they claim they are enough physically active. The biggest issue remains stress, which is being dealt with on a daily basis.

Primary and PE teachers injure themselves less than once a year, most frequently they stretch a muscle or twist their foot. Mostly they like to educate PE, even though it can often be difficult. They are only partly pleased with their working environment.
By pointing out the most common health problems and sports injuries among primary and PE teachers, I would like to help them avoid these kind of problems and stay healthier, stronger and more capable of solving their daily issues.


Objective Male breast cancer(MBC) is a rare disease representing less than 1%of all malignancies.The objective of the study is to report clinicopathological characteristics,treatment patterns,and outcomes of MBC in Mansoura University Hospital,Egypt. Methods This retrospective study focused on male breast cancer patients during 10 years(2000-2009).The studied variables were data regarding general characteristics of patients,treatment modalities and survival. Results The series included 37 patients(0.8%of all breast cancer).The median age was 57.7 years(range:26-86 years).The main clinical complaint was a mass beneath the areola in 94.5%of the cases.Most patients had a locally advanced disease.94.5%of tumors were invasive duct carcinomas.The treatment was essentially surgery in 91.8%,followed by adjuvant radiotherapy(in 89.2%), hormonal therapy(in 56.7%) and chemotherapy(in 91.8%).Follow-up period ranged from 6-115 months.Local recurrence occurred in 4 cases and metastasis in 11 cases.The 2-year and 5-year overall survival(OS) rates were 81.6%and 60.5%,respectively.The 2-year and 5-year disease-free survival(DFS) rates were 68.4%,and 52.6%,respectively.OS was not significantly affected by any of the studied parameters.Factors influencing DFS were:T stage(P=0.05),positive lymph nodes(P=0.043),metastasis(P=0.004),and chemotherapy (P=0.046). Conclusions MBC is a rare disease and often diagnosed at a locally advanced stage.The management of male and female breast carcinoma is identical.Future research for better understanding of this disease is needed to improve the management and prognosis of male breast cancer patients.


An emerging scenario of using Electric Vehicles to provide reactive power support arises as the population of Electric Vehicles (EVs) increases significantly. In view of this emerging scenario, a new application of Particle Swarm Optimization is proposed in this paper, which is adopting Particle Swarm Optimization (PSO) in Vehicle-to-Grid (V2G) based reactive power dispatch. Rather than utilizing reactive power support from central generators, the proposed method aims at increasing reactive power support from EVs, which are distributed. Case study on a modified IEEE 9-bus system is done and results show that the proposed method can bring convincing benefits on voltage stability and power loss in the overall power system.

SUMMARY The effect of storing Cheddar cheeses at elevated temperatures on proteolysis and flavour development was examined. Cheeses were stored under the following ripening conditions: (1) 8 °C for 32 weeks (control); (2) 15 °C for 8 weeks then 8 °C for 24 weeks; (3) 17·5 °C for 8 weeks then 8 °C for 24 weeks; (4) 20 °C for 8 weeks then 8 °C for 24 weeks; (5) 15 °C for 32 weeks; (6) 17·5 °C for 32 weeks; and (7) 20 °C for 32 weeks. The rates of build up of products of proteolysis and flavour increased in the order of the above treatments and substantial acceleration of ripening was achieved. However, after 32 weeks at 17·5 °C and 16 weeks at 20 °C, cheeses received significantly lower preference scores than the control cheeses (P < 0·05) mainly owing to the development of off flavours. The maximum temperature at which cheeses could be stored for 32 weeks without reduction in quality was 15 °C. Cheeses stored at this temperature for the entire period had levels of products of proteolysis at 12 weeks of age which were similar to those of controls at 32 weeks, and estimations of age at 20 weeks which were similar to those of controls at 32 weeks.


Each individual member of an organization must recognize and lead innovation, which can be affected by human resource development (HRD) investments and organizational changes. In this study, we aimed to verify how HRD investment at the individual level relates to employee perceptions of organizational innovativeness and to examine how the intensity of organizational change, a situational factor at the organizational level, affects the relationship between HRD investment and employee perceptions of organizational innovativeness through multilevel analysis using hierarchical linear models. We performed an analysis based on the responses from 5184 workers and 125 companies where corporate-level and personal-level data were matched in a Human Capital Corporate Panel (HCCP) survey. HRD investment by employees was shown to increase the perception of organizational innovativeness. The results demonstrated that the intensity of organizational change moderated the relationship between HRD investment and the perception of organizational innovativeness. However, the stronger the organizational change intensity, the weaker the positive effect of HRD investment on the perception of organizational innovativeness. Finally, we presented theoretical and practical implications and further research tasks related to the HRD of corporations and open innovation.


An experimental study of physical realization to encrypt private information using chaotic cryptosystems is presented. In particular, we use chaos synchronization and a complex encryption function to hide the messages. In both cryptosystems; encryption and synchronization are completely separated with no interference between them. We apply this approach to encrypt private analog and binary information signals. The utilization of chaos synchronization and cryptography seems to make a contribution to the development of communication systems with higher security. Copyright c °2005 IFAC


The National Institution for Academic Degrees and University Evaluation (NIAD-UE) is engaged in awarding of academic degrees based on the accumulation of applicant's earned academic credits. These credits must be classified according to the contents of syllabuses and pre-determined criteria for the chosen disciplinary field. This course classification is carried out by the sub-committees whose members are well-versed in the syllabus of each course. Active Course Classification Support system (ACCS) was developed to support the course classification process of the sub-committee members. In this paper, we extend practical use of ACCS. In order to achieve it, it is necessary to verify the practicability in various disciplinary fields. The ACCS requires myDBc that is a keyword database to support the course classification. However, it is practically difficult to construct keyword databases to all disciplinary fields in advance. We therefore aim to confirm the effectiveness at the following steps. At the first step, the ACCS uses the course name list provided by NIAD-UE for each disciplinary field. After receiving sub-committee judgment for course classification in each year, myDBc is updated for next year's course classification. We show a numerical example to confirm the effectiveness of the steps in the field of Laboratory Technology.


were ragarded as lytic /Kl ->3)-D-glucanases. In the affinity chromatography, most of the lytic activity of the L-3 fraction together with very high protease activity showed no detectable affinity for the gel. It was recovered by washing with high salt solution and its nonadsorbed fraction did not show /?-(1-*3)-dglucanase activity.1} L-3, with such high protease activity, was further purified by affinity chromatography on a casein-Sepharose CL 6B column,2) equilibrated with 50niM phosphate buffer at pH 7.0. Elution was done as shown in Fig. 1. Wefound that none of the lytic activity was eluted when the column was washed with the buffer solutions. Under such conditions the lytic activity together with protease was strongly adsorbed on the column, but could be cleanly eluted with the same buffer containing 1 m NaCl. The eluates forming the corresponding enzymepeak were combinedand concentrated to 2ml using an AmiconDiaflo unit equipped with a YM-5membrane operating at 50 lbs/in2 pressure, and then dialyzed overnight against 10 liters of50him acetate buffer at pH 5.5. The purified enzyme preparation showed a single protein band on sodium dodecyl sulfate (SDS)-gel electrophoresis as shown in Fig. 2, and was found to be homogeneous on gel filtration of Bio-Gel P-30. It was completely

Xinjiang is a water-shortage province.Using the Laspeyres index and a complete decomposition model,a total-factor decomposition model was constructed to measure economic growth effect,industrial structure effect and water utilization intensity effect in Xinjiang from 2005 to 2010.Xinjiang is currently in the middle stage of industrialization,economic development has greatly boosted industrial water utilization in Xinjiang from 2005 to 2010,and the pulling power is very rigid.However,the intensity of water utilization and industrial structure restrain industrial water utilization in Xinjiang,the adjustment of industrial structure and reduction in intensity of water utilization restrains industrial water consumption strongly.The total-factor decomposition model was also applied to 15 cities in Xinjiang.The results show that economic growth is a positive driver of industrial water utilization for the 15 regions.Although the effect trend is the same,the intensity of effect varies from place to place.Therefore the government needs to establish corresponding policy according to the reality of each region's economic development,industrial structure and intensity of water utilization.Each prefecture should introduce advanced water-saving ideas,technology and equipment to improve water use efficiency,and strengthen technological innovation and cooperation with the surrounding regions.


CONTEXT
Physical changes following activity are well documented, but there is limited information about self-reported outcomes around competitive matches. High training volumes and poor recovery could predispose athletes to overuse injury. The purpose of this study was to identify the changes in daily athlete health measures before, during, and after the day of each match in high- and low-volume groups.

DESIGN
Prospective cohort.

METHODS
Fifty-five soccer athletes (age: 19.8 [1.2] y, 26 males, 29 females) provided daily measures of readiness, physical fatigue, mental stress, sleep quality, and soreness intensity match days, days 1 (D01) and 2 (D02) following matches, and standard practice days. Participants were grouped into high volume and low volume, based off the minutes played during the season.

RESULTS
Soreness increased, readiness decreased, and fatigue increased on D01 compared with match days (P < .008) in the high-volume group. Between groups, the high-volume group demonstrated higher soreness on D01 and D02, lower readiness on D01 and D02, and lower fatigue on D01, compared with the low-volume group (P < .008).

CONCLUSIONS
Soccer athletes demonstrate significant changes in self-reported athlete health variables around competitive matches. These changes are similar to physical outcomes, potentially indicating that the athlete health variables may be used to track athlete recovery from competition, potentially limiting the impact of overuse injuries.


Background One of the greatest health issues in the world is colorectal cancer. It was formerly believed that this illness only affected residents of industrialized nations; however, recent research has shown a growing prevalence in underdeveloped nations. The majority of individuals in Nigeria report their cases at a stage when curative resection is not feasible; hence, increasing understanding and awareness of early symptoms as well as early detection techniques and screening tools have been highlighted as crucial for greater success. Aim This study elucidated the awareness, knowledge, and risk factors of colorectal polyps among studied adults aged 40–65 years of age in Imo State, Nigeria. Methods The sample of the study comprised a thousand (1000) adults drawn through a multistage sampling selection method and included urban and rural dwellers in selected communities in Imo State, Nigeria. A pre-tested, semi-structured questionnaire was the main instrument of data collection for awareness, knowledge, and risk factors for colorectal polyps. Statistical Package for Social Sciences (SPSS) Version 17 was used for analysis. Results Findings showed that more than half of the respondents (62.5%) were aware of colorectal polyps; however, factors such as lack of funds (34.8%), inaccessibility to screening services (24.0%), absence of screening facilities (24.5%), and passive behavior towards screening service providers (31.8%) in healthcare centers affected regular screening among participants. Respondents possessed good knowledge of colorectal polyps, although there is a need for thorough sensitization on the risk factors of colorectal polyps, especially lifestyle behaviors. People who smoked more cigarettes per day were found to be more likely to develop colorectal polyps (AHR 1.878; 95% CI 1.018–3.463; P = 0.044) than those who smoked less (AHR 1.811; 95% CI 1.003–3.270; P = 0.049). The study found that subjects with both smoking and drinking habits had a significantly higher risk for colorectal polyps (AHR 2.073; 95% CI 1.196–3.593; P = 0.009) than non-smokers and those who drank fewer alcoholic drinks. Conclusion Relevant educational and screening interventions are required to promote early detection and management of colorectal polyps among adults in Imo State, Nigeria.


A randomized, double-blind, placebo-controlled, international multicenter trial was conducted, using 1.5 MIU subcutaneous interferon alpha-2a 3 times a week for 4 weeks in 170 patients (interferon, n = 125 or placebo, n = 45) with condylomata acuminata who had failed to respond to standard therapies. There was no difference in efficacy between the interferon alpha-2a and placebo treatment groups at 3 months after commencement of therapy. Although the recurrence rate at the end of 9 months' follow-up appeared lower in the interferon alpha-2a group than in the placebo group (9% versus 22%), this difference was not statistically significant. Most of the adverse events reported were typical interferon-associated mild to moderate flu-like symptoms. It is concluded that subcutaneous interferon alpha-2a, administered according to the current dosage and treatment schedule, is not effective as monotherapy in the treatment of refractory condylomata acuminata.


Abstract : Correlations were examined in humans of alpha and pi-glutathione-S-transferases (serum and plasma, respectively) and blood levels of iron, transferrin, ferritin, soluble transferrin receptor (sTfR) as well as Total Iron-binding Capacity (TIBC), and percent Transferrin saturation (%TS). Data analysis of ungrouped (unbinned) data indicated significant gender differences in the blood levels of iron, TIBC, ferritin, and %TS, with none seen with transferrin, sTfR, or the GSTs. Regression analysis of ungrouped data with alpha-GST as a response variable identified the interaction between age and iron as well as between age and percent iron saturation (%ISAT) as significant predictors of alpha-GST. Regression analysis using ungrouped pi-GST data, only resulted in a quadratic model with iron as the only significant predictor (R2 = 6.9%). Using binned data based on published clinical levels, it was seen that elevated levels of iron and sTfR are strong predictors of elevated alpha-GST levels. These associations were not seen using binned normal alpha-GST levels. Unlike regression analyses of the ungrouped data, regression analyses of binned pi-GST data indicated significant associations (elevated iron, normal transferrin) although not as strong as those seen using alpha-GST data.


Applications of ontologies exist that go beyond standard de- ductive reasoning and rather have the character of empirical discovery in knowledge/data. We analyse the inventory of OWL with respect to two such applications, namely to pattern-based ontology matching and to ontology-aware knowledge discovery from databases.


The nacelles of modern aeroengines are constantly increasing in size. Thus, engine air-loads are becoming more powerful and their importance for the aeroelastic stability is becoming more significant. The principal goal of this study is to answer the question of how unsteady airloads vary while shifting to transonic Mach numbers. The investigations are carried out by applying a finite volume Euler method to a harmonically oscillating annular wing. The results show that transonic effects in the case of an annular wing are essentially weaker than in the case of an airfoil. The order of magnitude of the variations is around 10%. Possible consequences for the aeroelastic stability are examined with the example of an elastically mounted annular wing in transonic flow. The shifts of the stability curves also remain within a range of 10%. In addition, an actuator disk method, which is frequently used for the simulation of the fan jet, is expanded in such a way that unsteady flows can be treated. Some unsteady air-loads are strongly dependent on the pressure jump across the fan.


Objective: to study the relationship between neurobiological, immune parameters and alexithymia in patients with epilepsy. Material and methods: 58 patients with epilepsy (26 men, 32 women) were studied. Temporal epilepsy was diagnosed in 25, frontal — in 16, and frontal-temporal — in 17 patients. The frequency and type of seizures, duration of remission, severity of seizures, level of alexithymia, and parameters of immunity analyzed. To assess the relationships, the analysis of variance MANOVA is used. Results: the influence of alexithymia and immunological factors CD4+ , CD4+ /CD8+ and CD8+ on the frequency of complex focal seizures (CFS) was revealed. With high CD4+ , CD4+ /CD8+ values and low CD8+ values, the CFS frequency increases, which has an unfavorable prognostic value. The combination of alexithymia and right temporal focus also led to an increase in the frequency and severity of CFS. Statistically signifi cant correlations were found between the alexithymia and the intensity of immunity (CD4+ / CD8+ ). Conclusions: the results obtained support the hypothesis of the so-called innate immune mechanisms of alexithymia. Determination of the level of alexithymia can be used to predict the course of epilepsy.


Fluorescence in situ hybridization(FISH) has proven to be a very useful technique for the study of chimerism and microchimerism (2,4). Based on the detection of sexchromosomes, this technique allows for the identification and localization of donor and recipient cells in cases of sex-mismatched transplantation or cells from mothers and their male fetuses in studies of fetomaternal cell trafficking. For the further assessment of chimerism, the combinationof FISH and techniques of protein detection allows for the determination of the phenotype of persistent chimericcells. However, such combined techniques have proven to be difficult to apply to paraffin-embedded tissue specimens, which is the common preparation of tissue samples following biopsy, surgery, or autopsy.


The fields used to describe the influence of masses and electric charges are generally accepted to emanate at the speed of light from their sources. To obtain these fields for a moving particle which are consistent with special relativity, transformations should be applied to the emanating field in the particle's rest frame to acquire the field propagating in the particle's primed inertial frame. These transformations are of its coordinates, and also the velocity vectors of the field's propagation, which consequently lead to a change in the field's direction and as a result its density and strength. Yet, an electric charge's field propagation velocities are neglected and not currently transformed. This omission has consequences when it comes to transforming the field from the source's rest frame to the source's primed frame, as this primed frame's field would then be inconsistent with the calculated retarded field's directions and consequently its strengths in this primed frame. Here the retarded field of a moving point particle will be derived and from this the requirement of the velocity transforms and the aberrational effects will be shown. Hence, the full consistent inertial frame transform of the emanating field will be given. This work shows the general theoretical basis and legitimacy of the aberrational and time dilation effects on the field's density and thus strength and acts as an argument for their implementation on all luminally emanating fields.


The gluten free biscuit stick is a selection of food for the patients who are suffering from celiac disease. The objective of this study was to develop a gluten free product that had comparable organoleptic properties and nutritional value with commercial product. In this study, the gluten free biscuit sticks were prepared and being compared with the commercial product. Proximate analysis, moisture content, water activity, colour, total sugar content, Atomic Absorption Spectrophotometry (AAS), texture profile analysis (TPA) and sensory evaluation were being conducted to determine the properties of the gluten free biscuit stick and the commercial product. Gluten free product had the higher content of crude fiber of 4.96% ± 0.020, fat content of 15.13% ± 0.06 and potassium content of 26.94mg/L. Commercial product had the higher total sugar content of 4362.96 μg/g ±67.89,crude protein content of 57.51% ± 0.280 and ash content of 1.72% ± 0.199. Water activity was measured by using AquaLab water activity meter. Gluten free product had the lower water activity of 0.254±0.007 as compared to commercial product that had the water activity of 0.300±0.003 showed significant difference (p 0.05).


During the past 50 years, nuclear defense activities have produced large quantities of nuclear waste that now require safe and permanent disposal. The general procedure to be implemented involves the removal of cesium and strontium from the waste solutions for disposal in permanently vitrified media. This requires highly selective sorbents or ion exchangers. Further, at the high radiation doses present in the solution, organic exchangers or sequestrants are likely to decompose over time. Inorganic ion exchangers are resistant to radiation damage and can exhibit remarkably high selectivities. We have synthesized three families of tunnel-type ion exchangers. The crystal structures of these compounds as well as their protonated phases, coupled with ion exchange titrations, were determined and this information was used to develop an understanding of their ion exchange behavior. The ion exchange selectivities of these phases could be regulated by isomorphous replacement of the framework metals by larger or smaller radius metals. In the realm of layered compounds, we prepared alumina, silica, and zirconia pillared clays and sodium micas. The pillared clays yielded very high Kd values for Cs+ and were very effective in removing Cs+ from groundwaters. The sodium micas also had a high affinity for Cs+ but an even greater attraction for S42+. They also possess the property of trapping these ions permanently as the layers slowly decrease their interlayer distance as loading occurs. Sodium nonatitanate exhibited extremely high Kd values for Sr2+ in alkaline tank wastes and should be considered for removal of Sr2+ in such cases. For tank wastes containing complexing agents, we have found that adding Ca2+ to the solution releases the complexed Sr2+ which may then be removed with the CST exchanger.

Purpose – The purpose of this paper is to examine the role that knowledge acquisition (KA) plays in creating product innovation flexibility (PIF) in SMEs. The paper also examines two of the factors of the KA process: relationship quality (RQ); and information capability (IC). Design/methodology/approach – The survey data were checked for common method variance, validity, and reliability. Structural equation modeling was used to test the hypothetical framework and path analysis was used to test mediation effects. Findings – Results show that for SMEs, KA mediates the effect of RQ on PIF, and that KA partially mediates the relationship between IC and PIF. Research limitations/implications – The study focusses on only one step in the knowledge management process – KA. Additional research into the role that IC plays on PIF is also called for. Additional empirical study is needed to identify contingency factors, both within and outside the firm. Practical implications – These findings provide important insight...


Limit-periodicity describes structures without translational symmetry but which are the union of infinitely many patterns with translational symmetry on increasing scales. Because of its relative simplicity, the limit-perodic Socolar-Taylor tiling offers an ideal system to probe the physical consequences of this distinct type of order. In this undergraduate thesis, we construct a two-deminsional lattice model that possesses this tiling as its ground state, and investigate its properties through simulation and analysis. We find that during a slow quench from the high temperature, disordered phase, the ground state emerges through an infinite series of phase transitions. These transitions are related through scalings of an effective temperature and interaction energy. The system enters a glass-like state during a rapid quench due to the creation of kinetic barriers resulting from a simultaneous occurance of these transtitions. The diffraction pattern of the system is computed for fully and partially ordered states.


In this paper, there is analyzed the disturbances to impact on COMS attitude and the attitude error using the received telemetries in KARI ground station during normal mode of COMS. COMS was launched successfully at Kourou, French Guiana on the 26th of June, 2010. Up to now after IOT(in-orbit test), COMS is performing well the main mission to measure meteorology and ocean during about half and one year. The disturbances to impact on COMS attitude are mostly by the Sun, by the motion of payload mirror and by the spike happened during operation of earth sensor mirror and wheel. The analysis result on the other cases happened rarely during the nominal operation, is summarized.


In September 2007, a group was formed at the initiative of Professor Paul Kruger Andersen (University of Aarhus) and Professor Theodor Baums (Goethe University, Frankfurt) with a goal to draft a "European Model Company Act" (EMCA). The group was composed of prominent professors from different Member States of the European Union (EU). The main goal was to draft a model corporate statute, that can be adopted by the Member States and also by states outside the European Union and Europe in whole or in parts. In September 2015, eight years after the initial formation of the group, the EMCA was presented at the Wirtschaftsuniversität Wien in Vienna at the annual conference of the European Company and Financial Law Review (ECFR) in order to benefit from comments and discussions.


Shifts are a well-known feature of the literature on spacetime symmetries. Recently, discussions have focused on so-called dynamic shifts, which by analogy with static and kinematic shifts enact arbitrary linear accelerations of all matter (as well as a change in the gravitational potential). But in mathematical formulations of these shifts, the analogy breaks down: while static and kinematic shift act on the matter field, the dynamic shift acts on spacetime structure instead. I formulate a different, 'active' version of the dynamic shift which does act on matter, and analyse the consequences of this reformulation for Newton-Cartan Theory and Maxwell Gravitation.

We report on a theoretical study of the π− p → a1−(1260)p and π−p → π− ρ0p reactions near threshold within an effective Lagrangian approach. The production process is described by t-channel ρ0 meson exchange. For the π−p → π−ρ0p reaction, the final π−p0 results from the decay of the a1(1260) resonance, which is assumed as a dynamically generated state from the K*K̄ and ρπ coupled channel interactions. We calculate the total cross section of the π−p → a1−(1260)p reaction. It is shown that, with the coupling constant of the a1(1260) to ρπ channel obtained from the chiral unitary theory and a cut off parameter Λρ ∼ 1.5 GeV in the form factors, the experimental measurement can be reproduced. Furthermore, the total and differential cross sections of π−p → a1−(1260)p → π−ρ0p reaction are evaluated, and it is expected that our model calculations can be tested by future experiments. These reactions are important for the study of the a1(1260) resonance and would provide further constraints on the properties of the a1(1260) state.


An integrated structure which uses the nearly ideal switch characteristics of an insulated gate field effect transistor to sample a pn photodiode will be described. This structure permits operation of the pn photodiode in a photon flux integration mode. This mode of operation is based on the fact that if a pn junction is charged to a reverse voltage less than its breakdown voltage and then open circuited, the rate of decay of charge stored on the space charge capacitance with zero incident illumination is independent of junction area and can have a time constant in the order of tenths of a second. Under illumination this rate of decay of charge depends linearly on the intensity of the incident illumination. That is, the charge removed at any instant of time is proportional to the time integral of illumination. The insulated gate field effect transistor provides a high conductance when in the ON condition to charge the space charge capacitance and a very low conductance during the integration time. This structure lends itself very nicely to monolithic integration of linear arrays where individual photodetectors are sampled periodically on a time-shared basis. Such arrays may be sampled in any order providing the possibility of spatially preprocess information. This device provides not only better sensitivity but also improved S/N ratio over other electronic imaging devices. Several advantages offered by this device are: (1) linear dependence of signal on light intensity over several orders of magnitude; (2) electronically controllable sensitivity; (3) ease of integration into arrays for image sensing.

Polysomnographic recordings were obtained in six patients with idiopathic short stature (ISS), aged 4-10/12 to 16-1/2 yrs and seven patients with growth hormone deficiency (GHD) aged 6-3/12 to 10-5/12 yrs. ISS patients had GH levels ≥ 10 ng/ml and GHD patients had GH levels ≤ 7 ng/ml during provocative testing. Both groups had growth velocities below the 50th percentile and all patients were euthyroid. The results of the polysomnographic recordings (mean ± SD) are shown below for ISS, GHD and normals aged 6-13 yrs.ISS and GHD patients had identical percentages of stages of 1-4 and REM sleep. Both groups had significantly less REM and more stage 1 and 3 sleep (%) than normals. ISS patients had qualitatively, poorer sleep with an average of 66.7 minutes of wake-time during the sleep period as compared with <10 min. in GHD and normals. There was no correlation between wake-time and mean GH concentrations or secretory rates, although some ISS patients had very low mean GH range (2.0-9.5 ng/ml).Conclusions: Sleep architecture is abnormal in ISS and is indistinguishable from that seen in GHD. Coupled with low mean GH seen in some ISS patients, these abnormalities may be the cause(s) for the growth retardation in ISS.


Recommender systems have become prominent in past years. Today, many service providers use recommendation systems. Considering the number of products and customers, it is crucially important and necessary to meet the right products to the right customers. Various methods have been applied for recommendation systems. In our study, it is aimed to examine the purchasing relationship between the products and recommend alternative products. To achieve this, product spaces have been created by applying Word2Vec and FastText models, which extract the relationship between words according to the frequency of occurrence of items, on the products in the same basket (Item2Vec). In addition, pre-trained models are applied to product names to measure the similarity and they are ensembled with Item2Vec models with different weights. The results obtained regarding the use of word embedding methods in product recommendation are reassuring and may be applied in following projects.


The rapid development of intelligent detection technology guarantees accuracy in the assembly process. Aiming to solve the quantitative inspection of the cylindricity of Large size pipe fitting, this paper presents an online method technology using a laser sensor and Digital twin technology. The detection system comprises visual positioning, servo drive, and laser displacement sensor information acquisition systems. After positioning by the machine vision camera system, the servo system and laser displacement sensor scan the large-size pipe fitting layer by layer and establish the information interaction between physical space and virtual space through digital twinning technology. The digital twin scatters information model was found to calculate the maximum tangent circle and minimum peripheral circle, fitting the curve area of the closed point cloud layer by layer. And the least square method was used to calculate the center of the layered circle. The radial deviation of pipe fitting was evaluated comprehensively. The system makes a linear fitting of the center of the most miniature square circle of each layer, compares its deflection Angle with the solid center line, and calculates the center line deviation of the hole. Finally, the precision of the proposed method was validated by varying experiments. The cylindricity measurement of pipe fittings with an inner diameter of 300mm and height of 270mm was carried out by a pair of C-shaped semicircles fixed by the radial assembly. The cylindricity of the pipe fitting is 0.2372mm.


The problem addressed in this thesis is discrimination of gases with an array of partially selective gas sensors. Metal oxide gas sensors are the most common gas sensing technology since they have, compared to other gas sensing technologies, a high sensitivity to the target compounds, a fast response time, they show a good stability of the response over time and they are commercially available. One of the most severe limitation of metal oxide gas sensors is the scarce selectivity, that means that they do not respond only to the compound for which they are optimized but also to other compounds. One way to enhance the selectivity of metal oxide gas sensors is to build an array of sensors with different, and partially overlapping, selectivities and then analyze the response of the array with a pattern recognition algorithm. The concept of an array of partially selective gas sensors used together with a pattern recognition algorithm is known as an electronic nose (e-nose). In this thesis the attention is focused on e-nose applications related mobile robotics. A mobile robot equipped with an e-nose can address tasks like environmental monitoring, search and rescue operations or exploration of hazardous areas. In e-noses mounted on mobile robots the sensing array is most often directly exposed to the environment without the use of a sensing chamber. This choice is often made because of constraints in weight, costs and because the dynamic response obtained by the direct interaction of the sensors with the gas plume contains valuable information. However, this setup introduces additional challenges due to the gas dispersion that characterize natural environments. Turbulent and chaotic gas dispersal causes the array of sensors to be exposed to rapid changes in concentration that cause the sensor response to be highly dynamic and to seldom reach a steady state. Therefore the discrimination of gases has to be performed on features extracted from the dynamics of the signal. The problem is further complicated by variations in temperature and humidity, physical variables to which metal oxide gas sensors are crossensitive. For these reasons the problem of discrimination of gases when an array of sensors is directly exposed to the environment is different from when the array of sensors is in a controlled chamber.


urpose. The current study aims to use existing literature to examine the antecedents and constraints of new constructs, namely unethical yet beneficial for the organization. Approach. We conducted an extensive literature review of 46 published papers between 2010 and 2020 using multiple sources such as Web of Science and Scopus. Findings. Literature addressed two essential characteristics of unethical behavior within an organization. Initially, market intensity, followed by misleading favorable to hierarchical behavior, known as unethical pro-organizational behavior (UPB). Findings also suggestthat to eliminate such behavioral inclinations, organizations should clearly communicate their valuesand goals. Implications for practice. The current study has a lot of management implications. As past literature implies that employees are more likely to engage in UPB, firms must ensure that systems are inplace to limit the chance that workers would engage in such conduct, considering it is potential to harman organization's reputation.


Aiming to characterize the nutritional limitations on growth, nutrition and total flavonoids concentration of the Dimorphandra mollis, an experiment was conducted in a greenhouse with 0-20 cm samples of an Oxisol under Cerrado vegetation. The experimental design was completely randomized with 13 treatments and three replications. The treatments consisted of fertilization with missing element technique (with omission of liming and each one of the macro and micronutrients N, P, K, S, B, Cu, Fe and Zn). Dimorphandra mollis plant is tolerant to acid soil and responsive to the omission of phosphorus and potassium. The total flavonoids concentration was not influenced by the treatments.


Rinsing with sodium hypochlorite and hydrolysis with hydrochloric acid are two key procedures for the preparation of microcrystalline cellulose from apple pomace. In the present study,based on single factor experiments,by which hydrolysis time of 50 min and temperature of 100 ℃ were determined,the pairwise interactive effects of material/liquid ratio,hydrochloric acid concentration and the amount of sodium hypochlorite addition on microcrystalline cellulose yield were discussed by central composite design (CCD) in combination with response surface analysis. The significance of the above three factors affecting microcrystalline cellulose yield decreased in the following order:hydrochloric acid concentration material/liquid ratio the amount of added sodium hypochlorite. Analysis based on response surface and contour plots showed that all the pairwise interactions significantly affected microcrystalline cellulose yield. The regression equation based on the results from CCD design was resolved,and the results indicated that the optimal amount of added sodium hypochlorite for rinsing apple cellulose was 2.5 mL/100 mL,and that the optimal hydrolysis effect was achieved by the use of 6% hydrochloric acid to hydrolyze the substrate diluted 25-fold by volume. Under these conditions,a microcrystalline cellulose yield of 69.5% was obtained.

This Letter presents neutron diffraction data from a novel, biologically relevant, lyotropic membrane system which is highly alignable (#1.0± mosaic) in a magnetic field and gives rise to a number of welldefined Bragg reflections. The system, composed of two different phosphorylcholine lipids, undergoes a rare nematic ! smectic phase transition upon doping the system with paramagnetic ions (e.g., 2.7 wt % Tm31). In addition, the isotropic phase occurs at a lower temperature than the smectic phase, in contrast to other lyotropic systems and in contrast to the phase behavior predicted by the McMillan model [Phys. Rev. A 4, 1238 (1971)] of smectic ordering. [S0031-9007(96)02290-9]

The reaction of a series of organocuprate systems containing alkyl, aryl, alkynyl, silylalkyl or phenylthio groups with (1) is reported. Some of these organocuprates showed electron transfer properties and were relatively unreactive toward conjugate addition, hence have potential synthetic application as organocuprates involving an external electrophile.


We developed printed electronics compatible planographic printing methods that enable single-micrometer-order patterning with high rectangularity and thickness uniformity. Instead of conventional planographic printing methods where selective wetting is used for pattern generation, an adhesive latent image produced on a silicone surface is exploited for patterning in the proposed printing methodologies. We further investigated the fundamental mechanisms of the proposed methods by focusing on adhesion contrasts between the blanket, printing area, and non-printing area of a printing plate (PP) and determined that printing is feasible when a simple magnitude relation of adhesions is satisfied for thin layers of size ranging from approximately 50 nm to 100 nm. Latent image formation can be carried out via a simple ultraviolet exposure of the silicone surface, thereby enabling the rapid prototyping of printed device fabrications. The easily preparable, single material-based flat PPs developed in this study have the advantages of flexibility in pattern designs, washing process, fabrication cost, and pattern-rewriting capability compared with the conventional printing methods in which raised surfaces such as stamps or clichés are required for patterning.


A low-power 8-bit embedded microcontroller was proposed,which consisted of reduced instruction set computer(RISC)-like instruction set architecture,Harvard separation-bus architecture and a two-stage four-phase pipeline.Power distribution was emphasized in this research with power consumption optimized at system,register transfer level(RTL) and logic level.An experimental chip was fabricated using Chartered 0.35 μm CMOS Logic process.The measurement results indicate that the microcontroller can function well at a frequency of 80 MHz and the power consumption is approximately 6.75 μA under 32 kHz.As controlling core,the microcontroller is used in nonmagnetic measurement SoC chip to achieve data processing and dispatching.


Ectopic thyroid is a very rare developmental anomaly of descent of the thyroid gland. Most of the patients present with a asymptomatic midline neck mass and the diagnosis is easily mistaken for a thyroglossal cyst. Differentiation of these two conditions is extremely important, since removal of the sole functioning thyroid tissues result in permanent hypothyroidism. Therefore, many diagnostic tests including thyroid function test, ultrasound of the neck and thyroid scanning had been recommended in the preoperative evaluation of a thyroglossal cyst. The necessity of these tests was questioned by many authors and still is a subject of controversy. Treatment options of ectopic thyroid include both hormonal therapy and surgical intervention, but the role of each option is not clearly identified.


A method of deploying an electrical submerged pump (ESP) 125 into a well under pressure is disclosed. A first barrier means 117, is deployed within the well at a depth greater than the length of the ESP 125, sealing the well and providing a chamber 101 isolated from the downhole pressure. ESP assembly 125 is lowered into the chamber 101. A seal is made about lowering line 128, the barrier means 117 removed (or opened) and the ESP 125 lowered into the well to the required depth. In one embodiment the barrier means is a collapsible packer that on release is removed from the well. In a further embodiment a stinger on the lower end of the ESP engages with an assembly comprising the packer and a valve, upon release of the packer the assembly is transported with the ESP down into the well. A further method is disclosed in which a seal is maintained about the ESP components as it is lowered into the well.

He will take over the position after the publication of the present backlog of abstracts. Through the present time we have abstracted the abstracts collated in the Index Medicus, condensing them to about one fourth of the original text and publishing all abstracts and citations relevant to the field of headache and related disorders (discrimination was used only with regard to the categories of "headache secondary to organic disease", "orofacial pains", and "other topics of interest"). When Dr. Moore becomes editor there will be a change in the format of the abstract section. Instead of condensing all of the abstracts, Dr. Moore will pick out the most important papers and publish their abstracts in full, citing all others. This method will not require the rewriting and condensation of abstracts while continuing to disseminate all the pertinent research and reviews particularly relating to primary headaches. The past years of abstracting world literature have been a rewarding but arduous task. We are sure that Dr. Moore will do a superb job in continuing this important service.

The aim of this note is to present the recent results by Buckmaster, Cao-Labora, and Gómez-Serrano [Smooth imploding solutions for 3D compressible fluids, Arxiv preprint arXiv:2208.09445, 2022] concerning the existence of "imploding singularities" for the 3D isentropic compressible Euler and Navier-Stokes equations. Our work builds upon the pioneering work of Merle, Raphaël, Rodnianski and Szeftel [Invent. Math. 227 (2022), pp. 247–413; Ann. of Math. (2) 196 (2022), pp. 567–778; Ann. of Math. (2) 196 (2022), pp. 779–889] and proves the existence of self-similar profiles for all adiabatic exponents

 in the case of Euler; as well as proving asymptotic self-similar blow-up for

 in the case of Navier-Stokes. Importantly, for the Navier-Stokes equation, the solution is constructed to have density bounded away from zero and constant at infinity, the first example of blow-up in such a setting. For simplicity, we will focus our exposition on the compressible Euler equations.


The differences in the content of green (chlorophyll a + b) and yellow-orange (carotenoids) pigments in the leaves of 7 cultivars of spinach (Spinacia oleracea L.) and New Zealand spinach (Tetragona expansa Murr.) and their effect on black bean aphid (Aphis fabae Scop.) invasion were investigated in 2007 and 2008. In both years, the largest numbers of total aphids and colonies were observed on the cultivar Olbrzym Zimowy, whereas, the fewest ones – on Tetragona expansa. The high percentages of plants infested by total aphids and winged migrants, and the largest numbers of winged aphids were found on two cultivars: Matador and Markiza. The cultivar Matador was characterised by the highest yellow-orange pigments content in leaves and the highest ratio of these pigments to green ones. In both years, on the cultivar Spiros F1, small numbers of aphids and small percentages of infested plants were observed. The cultivar Spiros F1 was characterized by the lowest content of pigments (chlorophyll a + b, carotenoids) in leaves. The influence of yellow-orange pigments on the A. fabae invasion was confirmed by the statistically significant and positive correlation coefficients between the carotenoids to chlorophyll (a + b) ratio and the number of winged aphids and colonies, and also the percentages of infested plants by total aphids and winged migrants.


A novel surface emitting laser diode beam steering device based on the excitation and emission of surface modes is presented. This new device is a longitudinally segmented wavelength tunable GaAs/AlGaAs double heterostructure laser diode, which is modified to allow a coupling of the laser mode to a transverse electric polarized surface mode. This results in surface emission with very narrow beam divergence. A steering of the surface emitted farfield pattern is achieved by a variation of the emission wavelength: By electrically changing the emission wavelength from 877.54 nm to 879.13 nm the dominant surface emitted peak is steered by 0.4 degree(s).

Initial diffusion of prostate cancer (PCa) occurs in the regional lymph node (LN) stations. Positive LNs represent a significant adverse prognostic factor in PCa and can be associated with systemic metastases (1,2). Several anatomic studies with extensive lymphadenectomy have demonstrated that the obturator fossa is not always the primary site for LNs metastasis: therefore, pelvic LN dissection (LND) limited to the obturator fossa can miss about 50% of LN metastases. Therefore, an extended pelvic LN dissection (ePLND) should be performed in all intermediate-high-risk PCa, while a limited LND should be avoided, for the high risk of missing at least half the nodes involved (3).


New x-ray chemical micro analyzer for the invesitgation of chemical elements spatial distribution and for the element analyis has been designed. Characteristics of a new device and possibilities of its application are considered.


InGaAsP three‐dimensional optical waveguides with p+‐n junctions are described. A p+‐InGaAsP/n‐InGaAsP/n+‐InGaAsP double‐heterostructure rib‐type waveguide, which is suitable for monolithic integrations, was fabricated on an n+‐InP substrate by liquid‐phase epitaxial growth and chemical etching. Transmission loss as low as α=1.2 cm−1 was observed for deep‐etched rib‐structure passive waveguides at λ=1.318 μm TE fundamental mode. Additionally, electroabsorption of the waveguide layer material, In0.78Ga0.22As0.48P0.52, was determined at Eg −ℏω=0.09 eV. This measured electroabsorption will be a good guide for designing InGaAsP electro‐optic and/or electroabsorption‐type modulators.

Experimental researches with using fibrin adhesive glue for hermetisation pyelourethroanastomoses at 60 white rats are cared out. Anastomoses are processed twice by fibrin adhesive glue in experimental group. There is only suture in control group. Anastomoses at experimental group were more hermitically. The next results are received. There are more intensive process of reparation in experimental group. Granulation tissue in experimental group is formed and matered earlier than in control group. There is no reaction of neutrophils. Collagen fibres formed earlier, therefore forms more fast scar without deformation of lumen of anastomosis.


Strong interaction between a pion and a nucleon may develop in the process of elastic (p-p)-scattering. It is concluded that the peculiarities in this scattering are dependent on the mechanism inevitably produced as a result of the known optical relationship between elastic and inelastic processes.

CAD systems provide convenient tools for the creation of simple geometry by direct manipulation on the computer screen. They work well enough for two-dimensional construction, but are often inadequate for creating doubly-curved three-dimensional surfaces. The solution proposed here is to use the in-built programming language provided in most CAD systems for direct creation of geometry. Developed for didactic purposes, the stunning reconstructions of Gothic vaults suggest a method of working likely to be of great value to the geometrically adventurous architect.


Recent results on the development of active metallic nanocavities integrated with organic dye molecules in a J-aggregate state will be presented. Highly efficient SERS, the photoluminescence enhancement and photoluminescence lifetime modification have been observed at nanowire junctions.


Metric trees are designed for improving efficiency of similarity search in high dimensional data. Searching a metric tree always terminates at leaf nodes, restricting the hierarchical search to a certain leaf level, and the linear search in leafs to a particular leaf size. This may result in performing additional unneeded distance comparisons, which increases the search time as the number of dimensions increases. It is proposed that the search adapts itself to the query in question, so as to avoid unneeded distance comparisons. Thus, the hierarchical search should terminate when no more search- space pruning can be useful, and search then continues linearly through the un-pruned data space. Hierarchical search can thus stop any where above or below the original leaf level of a metric tree. Search rules are proposed to adapt the search to the query parameters. A modification to the metric tree is also suggested to adopt the proposed rules. High dimensional gene expression data sets are used to evaluate the new algorithm, showing speed ups of 55% compared to traditional search.


Based on data from a survey of all countries in the European Union (UE25), we attempt to comprehend the way in which European societies link concepts of citizenship (based on the possible transfer of voting rights in cases of geographic mobility) with their voting preferences (based on preference for a candidate from either their country of origin or the destination country) in the hypothetical case that survey respondents were to migrate to another country in the European Union. The results show a significant correlation between four different notions of citizenship in cases of mobility (nation-based, state-based, cosmopolitan, and based on the forfeiture of voting rights) and the preferred candidate's country of origin. A nation-based view of citizenship is linked to a preference for candidates from the respondent's country of origin, while respondents with a state-oriented view of citizenship are likely to prefer candidates from their country of destination. The conclusions drawn from this exploratory study allow us to further reflect on the explanatory factors that influence these conceptions of nationality and citizenship (within the current context of economic and social crisis), as well as on the effect this set of public opinion may have on the future of the European Union as a supranational, democratic political project.


We demonstrated recently that mice with ubiquitous, widespread over expression of Receptor Activity‐Modifying Protein‐1 (RAMP1), an obligatory subunit of the calcitonin gene‐related peptide (CGRP) receptor, exhibit increased baroreflex sensitivity (BRS) and resistance to angiotensin II (AngII)‐induced hypertension [Hypertension 2010]. In the present study, we tested the hypothesis that nervous system CGRP receptors mediate these protective effects. Blood pressure (BP) and heart rate (HR) were measured by telemetry in Nestin/hRAMP1 transgenic mice (n=5) with human RAMP1 targeted to the nervous system and littermate control mice (n=4) [Zhang et al., J Neurosci 2007], before and during Day 7 of AngII infusion (osmotic minipump, 1000 ng/kg/min). hRAMP1 expression was detected in nervous system but not in heart, kidneys and stomach of Nestin/hRAMP1 mice. In control mice, AngII infusion increased BP, and decreased HR variability (HRV) and BRS (sequence technique) (Table, AngII vs. baseline, * P<0.05). These deleterious effects of AngII were abrogated in Nestin/hRAMP1 mice (Table, Nestin/hRAMP1 vs. controls, † P<0.05).


Aiming at promoting the collaborative development of the multimedia business in the Asia-Pacific region, the Asian Multimedia Forum (AMF) was established in June 1997. This paper outlines the multimedia trials being implemented or planned in the AMF mainly from the network perspective.


ew ChrIstIaNs would reCall luXeuIl as aN ImportaNt plaCe IN ChrIstIaN history, yet it was instrumental in the expansion of Irish monasticism in europe and certainly the expansion of Christianity in the area now known as France. In fact this establishment has been called a "French monte Cassino" and "the holy spirit of the west."1 the leader of the monastery holds a more familiar name, Columbanus, or as he has many times been called, Columban. His influence on the growth of Christianity in France is of such significance that one would have to wait until the twelfth century, the era of St. Bernard of Clairvaux, before there existed a saint "exercising a comparable ascendancy in France."2 This upcoming year, 1992, marks the fourteen hundredth anniversary of Columban's monastic settlement at Luxeuil in 592.3 Due to its significant role in Christian history yet unknown status among many Christians, it is beneficial to consider the importance of Luxeuil and the role Columban played in its development. Columban was born in Ireland on the borders of the present counties of Carlow and Wexford about the year 543. He studied grammar, rhetoric, geometry and scripture in the Irish monastic schools. Not only was he a student, but he earned a name for his attractive appearance. His earliest biographer, a monk from the monastery of Bobbio named Jonas of susa, referred to his "formae elegantia." He entered the monastery of Congall at Bangor. These monks followed the Rule of Bangor which was known for its stern measures. There at Bangor, Columban learned Latin and some Greek, read the pagan classical authors and became immersed in the scriptures.4 he further possessed an interest in poetry which remained with him all of his life.5 Columban, in the spirit of Celtic pilgrims, had a desire to go abroad to perform missionary work but he was refused by his superior Congall. He was later able to convince this superior that this call to missionary work was from God. He set sail with twelve companions, their journey leading them to the shores of Gaul. After wandering through the countryside, they made a settleThe year 1992 will commemorate the fourteen hundredth anniversary of St. Columban's missionary expedition to Luxeuil. This site grew into one of the most important monastic settlements in Europe. St. Columban was a shining light of sacred and secular learning who clearly showed that the "Dark Ages" were not completely bereft of culture and godliness. This was due in no small part to the work of Celtic missionaries such as St. Columban.

Cardiovascular and cerebrovascular diseases are common diseases that endanger people's health. In this paper, 80 elderly patients with cardiovascular and cerebrovascular diseases treated in a street community health service center in Jiangsu Province in 2019 were selected as the observation group, and 80 middle-aged and young patients with cardiovascular and cerebrovascular diseases who visited the service center during the same period were selected as the control group to assess the overall risk of the patients. Based on the assessment results, integrated management of community prevention, treatment was performed on the elderly patients in the observation group. The awareness rate, treatment rate, control rate, attitude, behavior level, and other aspects of the patients for cardiovascular and cerebrovascular diseases before and after the management were observed and compared. The results showed that in the assessment of overall risk in the observation group, the prevalence of three risk factors (above the age of 45, hypertension, and elevated blood glucose) was significantly higher than that in the control group. After the implementation of management, the indexes, attitude, behavior levels, and detection rate of risk factor abnormality of the patients in the observation group were significantly superior to those in the control group (P < 0.05). Hence, the implementation of integrated management of community prevention, treatment, and rehabilitation can effectively improve patients' mastery of knowledge about cardiovascular and cerebrovascular diseases and play an important role in reducing the abnormal risk factors.


The USAID ASSIST Project partnered with the Journal of the International Association of Providers of AIDS Care (JIAPAC) to publish a special supplement on the Partnership for HIV-Free Survival (PHFS), a six-country quality improvement initiative supported by USAID aimed at keeping positive pregnant and lactating women healthy and their exposed infants healthy, nourished, and HIV-free. The nine articles in the supplement, listed and downloadable below as PDFs, focus on the design of the partnership, the quality improvement approach used in all countries, learning and knowledge-sharing modalities, and key results, challenges, and accomplishments including increasing retention of mother-infant pairs and decreasing mother to child transmission in several countries.


Abstract The use of horizontal drilling to improve oil recovery in coning situations is a technology that is gaining widespread application. This paper adds to the data base by evaluating the results of a horizontal well in a highly heterogeneous carbonate reservoir where both vertical gas coning and differential horizontal cusping occur. The complexities of designing, completing and testing the well are presented. The results discussed in this paper show that in situations where geologic uncertainty exist, a horizontal well can be repositioned during drilling. However, the additional cost involved can be more than offset by refining the seismic description in advance. The completion design should be kept as flexible as possible so that production can be made to converge on the optimum sections of the horizontal wellbore. A combination of logging, buildup and production testing before and during startup will help identify potential undesirable gas breakthrough. This can then be forestalled by refining the completion design accordingly.


In Missouri, there is a unique predator complex that suppresses soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), populations prior to reaching economic threshold. Preliminary research has shown that when soybeans were infested with soybean aphids under normal field conditions, populations did not become well established. However, when plants were caged to exclude predators, soybean aphid populations grew rapidly. To determine which predator is most responsible for suppression of soybean aphid populations in Missouri, soybean plants were caged using different size meshes. Three sizes of mesh were used; one which excludes all insects, one which excludes insects larger than thrips and one which excludes insects larger then Orius insidiosus (Say) (Hemiptera: Anthocoridae), a principal predator. As a control, cages were placed over soybean without mesh. Caged plants were infested with soybean aphid at the plant growth stages V5, R1, and R3. Fifteen aphids were transferred using a fine camel's hair brush to the uppermost expanded trifoliate. Soybean aphids used were colony reared and of the same ages (<48 hours). Sampling consisted of weekly visual observations of the caged plants for soybean aphids and aphidophagous predators; in particular, O. insidiosus (nymph and adult) and coccinellids (Coleoptera: Coccinellidae) (larvae and adult). Information gained from this study will allow us to assess the key soybean aphid predators at different soybean phenologies.


This paper deals with the experience of a private owner distribution utility in Argentina, face to the Governmental Regulatory Agency that controls the quality of service to the customers. Specifically the controls included the socalled "Disturbances Campaigns" aimed to register the harmonics component and flicker in the selected measurement points. The voltage level (over or under voltage) are also controlled with a separate campaign. A brief approach to the mandatory regulation (that specifies also the equipment to be used), the specific technical formulas to calculate the harmonic component that fulfil the Regulatory, and the eventual fine to be paid are detailed. Also are described the characteristics of the equipment used, and some results of the 2 900 measurements of harmonic components and flicker in different points of the distribution network.


A benchmark study on several closed-form solutions for the mean crushing strength and the cutting resistance of plated structures during collision or grounding is carried out by comparing theoretical solutions with experimental data. Based on expressions which have been derived for unstiffened structures, an extension of the methods is proposed for longitudinally and/or transversely stiffened structures. Dynamic effects on the crushing and cutting response are discussed, and applicability of the quasi-static formulations to analize the crushing and cutting damage of the structure in the dynamic situations is investigated.


Energy Efficiency and Environmental Protections is one of the major pillars that need to be considered seriously today more than ever to enhance life quality and to have a sustainable future. In addition, it is an indispensable path to reduce emissions, achieve climate change mitigation, and optimize operational expenses.
 As the leading in energy and environment protection, Saudi Aramco South Ghawar Producing Department (SGPD) spares no effort to explore innovative approaches and technologies to ensure a sufficient supply of energy to the world in an environmentally friendly manner. In spite of all the exerted efforts, strict policies, challenging targets and investments to achieve a continual improvement in energy efficiency, it would be hard to avoid a performance plateau without breakthrough solutions. This is particularly true in South Ghawar Producing Department (SGPD), considering the large geographical area in which different facilities are scattered.
 Saudi Aramco, as one of the world's leading energy and chemicals companies, is working to reduce greenhouse gas emissions and improve the environment wherever possible. The production of oil and gas in Gas-Oil Separation Plants (GOSPs) inevitably leads to some emissions of greenhouse gases, primarily from flare systems. A flare system is a critical safety system for any oil and gas producing facility. The flare deals with large volumes of hydrocarbons when facilities shut down or have upsets. During normal operations, a continuous small stream of purge gas is necessary to ensure the safe operation and availability of the flare system. While this purge gas rate is small, when added up for the multitude of Saudi Aramco's facilities, the purge gas represents a significant amount of hydrocarbons lost and greenhouse gases emitted. Furthermore, continuous operation at a low rate causes damage to flare tips, reducing their reliability and increasing maintenance and replacement costs.


Event synopsis: Is love something artificial, just a form of illusion? Many theorists have argued this, but why then do so many people experience it as real? In this Valentine's Day presentation, Stephen Frosh and Lynne Segal debate this and related issues, asking: Is love possible?


The hadron‐nucleus J/Ψ production is analyxed in a phenomenological picture, considering the parton recombination model. There is an evidence for a nuclear suppression effect, besides shadowing and we obtain good agreement with experimental data.
