Pterygium surgery has evolved a lot with newer technigues to help create better postoperative outcomes, to make the surgery time less consuming, to have fewer complications and to provide more better postoperative comfort to the patient. Our study is based on one of this new techniques of Conjuctivo Limbal Autograft with autologous serum which is comparatively less time consuming compared to its is precedessors and is a sutureless and glueless technique. The aim of the study is to find the safety, efficacy and relation of stability of intraoperative grafts (graft fixation) with their postoperative outcomes. We found that intra operative stable grafts to provide good results postoperatively having major displacement of only 1.15%.thus making this technique a faster, stable and economical technique for the patients and the doctors. patients, recurrent pterygium and history of any known bleeding disorders. Patients' data included age, sex, past ocular, medical and surgical history, visual acuity before and after surgery, surgical method and time for graft adhesion, operation time, complications, intra operative stability of graft, postoperative medications, postoperative assesment, recurrence.


Recent molecular dynamics investigations have shown that C 60 fullerites can be investigated by means of simple potentials and few calculations have focused on the pressure dependence of thermodynamic properties and the induced order-disorder phase transition. The aim of this work is to perform molecular dynamics simulation of the C 60 crystal lattice in the face centred cubic structure under progressively raised pressure, to illustrate the limits of the crude pseudo atom approach and the validity of the potential in the rigid molecule, when seeking for possible phase transitions. For that purpose, several thermodynamic and structural properties are calculated with different potential models in the pseudo atom approach and as a rigid freely rotating C 60 molecule. Calculated properties are compared to experimental data. It will be demonstrated that though the pseudo atom approach is reasonable in the low-pressure region (< 4 kbar), the rigid molecule is in better agreement with experiments depending on the choice of the model potential and the pressure applied. Orientational transition pressures are observed at 5 and 260 K, the distorted lattice and the cell contraction are measured and the density of phonon states is reported at different pressures.


This paper examines risk and resilience in relation to emotional abuse. Research has identified numerous child and family factors that may increase the risk of emotional abuse occurring and has also identified numerous ways in which an experience of emotional abuse can enhance vulnerability to negative outcomes. However, relatively little is known about the factors that determine the extent to which an experience of emotional abuse predicts later psychosocial functioning. Factors that may determine risk and resilience in children who experience emotional abuse are discussed. These include predisposing factors such as early caregiving experiences; precipitating factors such as the frequency, intensity and duration of the abuse; factors intrinsic to the child such as working models of the self and others, internal or external attributions, behavioural and coping strategies, self-esteem, and disposition; and external factors such as school and availability of supportive relationships. The need to pay attention to the particular vulnerabilities and protective factors pertaining to each emotionally abused child in order to most effectively enhance resilience is highlighted.


Most of the spatially moving vehicles and game controllers use 2-3 degrees of freedom joysticks to manipulate objects position. However, most of the spatially moving vehicles have more than 3 degrees of freedom, such as helicopters, quadrotors, and planes. Therefore, additional equipment like pedals or buttons is required during the manipulation. In this study, a passive Stewart platform based six degrees of freedom joystick was developed to control spatially moving objects. The Stewart platform mechanism is a six-degrees of freedom parallel mechanism, which has been used for simulators. The main challenge of using a parallel mechanism to manipulate objects is the computational burden of its forward kinematics. Therefore, an artificial neural network was used for the forward kinematic solution of the Stewart platform mechanism to obtain the fastest response. Linear potentiometers were used for the Stewart platform legs. A mathematical model of a quadrotor was used to test the capability of the joystick. The developed spatial joystick successfully manipulated the virtual quadrotor model. KeywordsSpatial joystick; Stewart platform.


A Multiplex PCR‐based assay (m‐PCR) with three sets of primers was developed for the detection of all serotypes of Salmonella enterica and the identification of Salmonella Enteritidis and Salmonella Typhimurium. This method was evaluated against a bacteriological method for the analysis of environmental swabs of poultry houses. Samples were pre‐enriched in phosphate‐buffered peptone water for 24 h and subjected to three different protocols prior to PCR: (i) an immunomagnetic separation using DynabeadsTM anti‐Salmonella (Dynal); (ii) a DNA extraction procedure using the InstageneTM matrix; (iii) an additional step of culture on an MSRV medium. With protocols 1 and 2, eight positive results were found by PCR and 20 with the bacteriological method. Protocol 3 combining MSRV and PCR gave similar results to those obtained from bacteriological methods and allowed Salmonella detection within 2 days.


With the expansion of Industry 4.0, the factory automation (FA) system has become more complex due to wireless communication between multiple devices. Therefore, short-term development and secure communication are required for development cost and cyber-security issues. For this reason, a secure robot operating system 2 (SROS2) was developed. SROS2 is an open-source platform applicable to industrial robots. SROS2 achieves short-term development with various libraries and implements encryption and authentication by embedding advanced encryption standard - Galois/counter mode (AES-GCM). On the other hand, AES-GCM has been reported to be vulnerable to spoofing. Therefore, a secure encryption algorithm to replace AES-GCM is required. In addition, the system must be able to operate without problems after replacement. For these reasons, this study embeds secure authenticated encryption instead of AES-GCM in SROS2. The results of an evaluation experiment on the latency of the encryption algorithm showed that Ascon is more effective than AES-GCM.


"Introspection" and "break" are important aspects of modernity.The progress of Chinese society in recent years always reflects the pursuit of the "break"of modernity.The constant pursuit of modernity in Chinese literature of the 20th century has submerged its essential spirit---introspection.The emergence of literature on lives of the needy shows the introspection on modernity.Binary opposition characteristic of the thinking mode in modernity,the conflict between city and countryside,the decline of the state-owned factories,etc.are discussed.


Some nano-electromechanical (NEM) nonvolatile memory cells will be discussed such as NEMory cells, T cells and H cells. NEM nonvolatile memory cells are considered as alternative embedded nonvolatile memory cells because they have advantages of CMOS-compatible process, high packaging density, board space saving, low program / erase voltage, large sensing margin, low fabrication cost and short time-to-market. Since the first CMOS-compatible NEM nonvolatile memory (NEMory) cell was proposed, T cell has been proposed for 2-bit operation and H cell has been proposed for 4-bit operation.


ion, where his attempt naturally fails to comprehend existence rationally. In weary reaction, his imagination makes one last desperate effort at some kind of explanation in the form of a consoling dream-vision whose powerful, dynamic imagery is drawn from the wondrous immensities of nature or the tragic confrontations with human finitude represented in Romantic art. (Byron's Manfred or Goethe's Faust are the best examples here.) By lapsing into a semi-conscious reverie, the solitary individual tries to impose a local habitation and a name upon that point of blank desertion where ultimate questions chronically go unanswered. (This is what Kierkegaard means by the Hegelian formulation, "the pantheism of the imagination.") When his voyage of discovery also founders, the skeptical young man makes an idol of the unknown itself, ultimately giving it a human countenance formed in the image of an idealized authority figure, most often the father, whose infinite creative power radiates like the sun and sanctions the human child's speculation that one can overcome death by transcending time. The ironic imagination thus repeatedly substitutes an increasingly exorbitant vision of its own (veiled) omnipotence for its experiences of finitude or what one could call an essentially Romantic interpretation of the sublime for the experience itself. Whether or not Kierkegaard's understanding of "unmastered irony" applies to Dickinson's poetry, it certainly seems to illuminate much of Tate's New Critical or "modernist" interpretation of her poetry. Much as other New Critics did with Hopkins at the same time, Tate reduces Dickinson's poetry to a schema of historical, psychological, and stylistic antitheses before he attempts to define its essence as irony, as it appears in such representative poems as 'The Chariot." Yet in the process, his own antithetical framework and language, as they mediate his dread, force him to look into the poetry for a principle of ideal synthesis or "fusion" to resolve formally the antitheses of his own interpretation. He cannot rationally justify this procedure, nor can he allow his interpretation to suffer the complete breakdown or "little death" an admission of its radical limitations would entail, so he valorizes Dickinson's imaginative power to coerce experience and make it conform to the imaginative form of desire. In this way Tate symbolically overcomes all limitations, even those prescribed by the certainty of our death to come. By having Dickinson triumph ironically over death itself, Tate reads into her poetry an idealized image of his own interpretive methodology. Dickinson thus becomes another holy name, another idolatrous effigy of the divine authority figure at the center of the critic's dream of creative, symbolic omnipotence a view of the writer and her relationship to language and to life which covers over the very fear and trembling, the painful experience of Negative Capability, at the heart of authentic creativity. I have analyzed Tate's "New Critical" interpretation of Dickinson primarily to expose its illegitimate substitution of poetry for religion and


The dynamic contact pressure distribution in a disc brake system remains impossible to measure through experimental methods. This makes numerical analysis using the finite element method an indispensable alternative tool to its prediction. However, the finite element model must first be validated through appropriate analyses so that realistic predicted results can be obtained. This paper proposes and carries out a three-stage validation methodology: validating the dynamic aspect of each brake component and the brake assembly using modal testing data and the contact aspect using the experimental results of static contact pressure. A detailed 3-dimensional finite element model of an actual disc brake was developed. Brake pad surface topography is also taken into consideration. Good agreement is achieved between predicted and experimental results both in modal analysis and static contact pressure distributions. Once a validated model was obtained, contact analysis for dynamic condition of the disc brake is performed.

A numerical study on the characteristics of dual-material gate nanowire tunnel field-effect transistor (DMG-NTFET) is presented using 3-D TCAD simulations in this paper. Compared with the single-material gate tunnel field-effect transistor (SMG-NTFET), the numerical simulation results demonstrate that the DMG-NTFET has lower leakage current IOFF with a negligible loss of ION. Moreover, the impact of two gates' work function difference on the DMG-NTFET ON/OFF current ratio, transconductance (Gm) and DIBL effects is studied, and the effect of control gate length on the ION and IOFF is demonstrated. Finally, the optimization design of the work function difference and the control gate length for the DMG-NTFET is discussed.


One of the accident of wire line squeeze and disorder is caused by the impact force happened on fast line during rig starting.Based on the dynamics theory of mechanics,a dynamics mode of rig lifting system was established,which can get the solution of the said problems of fast line pulling force.


A 74-year-old woman presented to our gynecologic division with right lower quadrant abdominal pain and fever (39 8C). The patient was complaining of a chronic lower abdominal pain since 1 year, which had increased in intensity during the last 2 weeks. She underwent hysterectomy with bilateral adnexal sparing 11 years before for utero-vaginal prolapse. Physical examination revealed tenderness in the right lower quadrant without signs of peritonitis (negative rebound tenderness). Neither urinary nor enteric symptoms were present (vomiting, diarrhea, and rectal hemorrhage). An abdominal mass in the right lower quadrant was palpated. No ascites were present. WBC was 9600/ml, while the other blood chemistry tests were normal A transabdominal ultrasound examination (US) showed a tubular-shaped structure (134 mm /60 mm in size) of mixed echogenicity, with poorly defined margins, occupying the right iliac fossa. By endovaginal US, we noted that the lesion was characterized by external linear echoes surrounding a hypoechoic and finely punctate center, suggesting a lumen. The outer part of the mass showed both longitudinal and transverse echo patterns, suggesting a bundled muscular structure, while the non-homogeneous echo pattern characterizing the center was compatible with very thick mucoid material. Considering that the external wall of the mass had features similar to the muscular layer of bowel wall and that the lumen seemed to be filled with dense fluid material, our hypothesis was that this pelvic mass was of intestinal origin (Figure 1). It was not possible to confirm by US the presence of intraluminal gas inside the mass. The fat surrounding the mass was normal. The left ovary was normal. It was not possible to see the right one. The cecum was not identifiable. No peritoneal-free fluid was present. Surgery revealed a large infected mass that was histologically diagnosed as a mucinous cystadenoma of the vermiform appendix.

In order to explore the effect of storage time on phenolic components of red wine,red wine from Cabernet Sauvignon was sealed in stainless steel tanks for 3 years,and variations in phenolic components and total antioxidant capability during aging period were detected.The results indicated that total phenols did not exhibit an obvious change after storage for 1 year;in addition,total flavonoids and total flavanols in red wine reached up to their respective maximum values,and then exhibited a gradual decrease with extended aging time.However,total anthocyanins revealed a gradual decrease.During the storage period,gallic acid gradually replaced salicylic acid as the major hydroxybenzoic acid,and the total content exhibited a gradual downward trend but remained higher than hydroxycinnamic acid,another phenolic acid.Among all the identified phenols,the content of catechin was the highest.Most of the identified phenols reached their peaks after 1 year of aging,followed by a progressive decline.During the whole aging period,the relative content of flavonoids was increased,while the relative content of non-flavonoids exhibited an opposite change.DPPH scavenging capability and cupric ion reducing anti-oxidant capacity(CUPRAC) reached their maximum values after aging for 1 year,and then declined gradually;in contrast,hydroxyl radical scavenging capability exhibited a gradual decrease throughout the aging period.In terms of DPPH scavenging capability and CUPRAC,hydroxycinnamic acid had stronger antioxidant activity than hydroxybenzoic acid;on the other hand,salicylic acid,quercetin and ferulic acid had strong hydroxyl radical scavenging capability.


In the last few decades, the transport law has been in a fragmental state, which is full of over-diversification of the provisions of the special norms and international conventions, laws and regulations, the general terms of the transaction. As matter of facts, it's constituted by a very vague, even unpredictable regulatory system. It is not only harmful to protect the safety of transactions, but also creates unfair competitive situation. This paper analyzes the necessity and possbility of harmonatiztion of transport law in China, and points out that harmonatiztion will help to the elimination of unfair competition and meet the needs of efficient and orderly transportation and logistics.


As competitions in marketing intensify and many marketers offer products that are similar, salespersons are forced to adapt their marketing strategies to survive. Relationship marketing has become the suitable strategy that salespersons employ to cope with this situation. Nevertheless, each and every customer is unique, so a better understanding of customers at the individual level is essential. Thus, this research examined the effects of cultural value orientations of customers at the individual level on the relationship between seller influence tactics, relationship quality, and customer loyalty. The questionnaire was launched to 511 respondents gathered from several central business districts in Bangkok metropolitan, Thailand. I employed the structural equation modeling approach to investigate the issues. The findings show that many relationship channels between coercive influence seller tactics, relationship quality, and customer loyalty which was influenced by a customer's cultural value orientation are not statistically significant. In contrast, quite a number of relationship paths between non- coercive seller influence tactics, relationship quality, and customer loyalty are significant. Moreover, the linkage between relationship quality and customer loyalty influenced by cultural value orientation is significantly strong.


In this study, we propose a real time and robust method for passport recognition and face verification which can automatically recognize passport codes and discriminate forgery passports to improve efficiency and systematic control of immigration management. Usually, the face recognition algorithms address two major challenges. The first is when an individual intentionally alters the appearance and features using disguises, and the second is when limited gallery images are available for recognition. Find String area of the passport code is an important stage in our method. In this system main stage is the isolation of the string area of the passport code, from the digital image of passport obtained by a scanner under different circumstances such as angle. The algorithm starts with preprocessing and signal conditioning. Next string area of the passport code is localized using morphological operators. Then the result of this process sends to segmentation part. Segmentation part separates the picture of passport holder and characters individually. Finally recognition part recognizes the face and characters giving the result as the passport is forged or not. The performance of the proposed algorithm is evaluated using three databases that comprise of real and synthetic face images with different disguise artifacts. The performance of the algorithm is evaluated for decreasing number of gallery images and various types of disguises. After several tests using a forged passport and the passport with slanted images, the proposed algorithm shows a better performance compared to other existing algorithms in recognizing passport images and get through a %96.8 accurate in the extraction of passport code region, and %94 accurate in the segmentation of the characters and %92 in the recognition of the characters. The accuracy of %98 in the face detection and %97 correct in face recognition was also achieved.


In this paper, we propose a component learning method to learn a set of Gaussian components that fit the given data distribution. An ordering and visualization technique called OPTICS and tests of multinormality are used in this method. We consider the applications of the proposed method to the tasks of classification and clustering. Here, the components are used to define a feature space to which the data points are transformed. In that feature space, classification is performed using linear support vector machines and clustering is performed using support vector clustering. The performance of the component learning method and its application to classification and clustering is demonstrated on synthetic datasets.


To investigate the effect of vacancy concentrations on mechanical properties of single crystal γ-TiAl, the uniaxial tension tests of γ-TiAl alloy models at different vacancy based on molecular dynamics simulation was performed. The results shows that obvious brittle behavior in stress-strain curve and ultimate stress decreases nonlinearly with increasing vacancy concentrations can be got. When the atom near vacancy is changed, potential energy reaches to maximum, and decreases with the increasing of vacancy concentrations. In the process of tension tests, vacancy gradually is evolved to the hole, and then the hole is evolved to micro cracks. Finally the micro crack extended until the material fractures. The form of crack propagation is different at different vacancy concentrations. Introduction In recent years, light and high temperature structure materials are focused on by research. TiAl alloy, as one of the new type structure materials, due to its low density, high conductivity, high specific strength and stiffness, and good capability of flame retardant and oxidation resistant, becomes the material which has huge development potential and application prospect of high temperature. It is widely used in aerospace and automotive. At present, the main applications in TiAl alloy are the engine with high-pressure turbine blade, low pressure turbine, excessive tube beam, exhaust valve, nozzle etc [1-8]. However, the application of TiAl alloy is limited by its damage and defects. In order to make full use of its excellent properties, and make it better used in aerospace, it is necessary to understand its characteristics. Point defect is widespread in crystal materials and is the basic structure of crystal materials. The distribution of point defect in crystal materials is random and disorder. Point defect has huge effect on mechanical properties of materials. Vacancy is one of the point defects, which appears on the location of atoms and only have a size of one atom. So, it is difficult to observe directly by experiment. Using molecular dynamics method to study on metal materials has more advantage than experiment. It can be used to simulate and analyze point defect directly, researchers are attracted by its simple modeling and accurate simulation results [9] The displacement cascades of neutron irradiation with various vacancy concentrations in bcc-Fe is simulated by Wang [10], the results shows that the defect annihilation is faster in the case of the higher pre-vacancy concentrations. The mechanical properties of single-crystal bulk Mg2Si is investigated by Yu [11], and the results shows that the ultimate stress decreases nonlinearly with increasing vacancy concentrations. Once such defects are present, there will be a substantial drop of the ultimate stress, and higher concentrations cause further decreases. Effects of vacancy defects on tensile mechanical properties of single graphene sheets are investigated by Han [12], the results shows that the new defects are likely to appearing near one or two atom vacancy defects, and there is a reduction in the tensile strength and failure strain. Because of the exising of vacancy, the effects of temperature and vacancies on crack in graphene sheet are investigated by Lohrasebi[13], the results shows that the presence of vacancy reduces the critical load giving different crack propagation 0175 4th Annual International Conference on Material Science and Engineering (ICMSE 2016) © 2016. The authors – Published by Atlantis Press trajectory. Generation and evolution of vacancy-type defects in nano-Cu films during plastics deformation are investigated by Xu[14] , the results shows that the plastic deformation appears near free surface due to the dislocation nucleation, both the generation and evolution of vacancy-type are related to dislocation activities. For the past few years, the research of γ-TiAl alloy at atomic scale is still very limited, the research of γ-TiAl alloy using molecular dynamics simulation method are as follows: the shear deformation[15], the tension deformation [16], phase transformation [17], void growth [18], fracture behaviors of <110> tilt grain boundaries [19], Super dislocation of asymmetric nucleation and movement [20]. Aiming at the shortcomings of the above research on γ-TiAl alloy, this work is analyzed for the effect of the vacancy concentrations on mechanical behavior of γ-TiAl alloy, and γ-TiAl alloy models which have vacancy concentrations of 0%, 0.008%, 0.012%, 0.016% and 0.03% are estabilished. Computational Model and Method The crystal structure of γ-TiAl is L10 (face centered square) crystal structure model [21]. Lattice constants are a=4.001 Å, b= 4.001 Å, c= 4.181 Å[18],the crystal structure is showed as Fig.1.


Isolated output pulse shapes are calculated for magnetoresistive gradiometer read heads having various geometric and magnetic parameters. The two‐dimensional finite‐element and reciprocity methods are used. The ferromagnetic shield has a big effect on the pulse shape, especially for closely spaces shields. High shield reluctance causes pulse broadening and large positive tails. Addition of a medium underlayer decreases the pulse undershoots and increases pulse amplitude. A reluctance model is given that explains most of the observed effects on pulse shapes and illustrates the importance of reluctance balance to achieve optimum pulse shape.


Fatigue in workers is a significant problem in the modern industry, largely because of high demand jobs, long duty periods, disruption of circadian rhythms, and accumulative sleep debt that are common in many industries. Fatigue is the end result of the integration of multiple factors such as time awake, time of day, and workload. It is known that fatigue has an association with work performance and increasing errors/accidents. This social and economic problem requires the full understanding of fatigue to its effective management at the workplace. In this work, we measure the regularity of the stride of human gait in a group of twelve people, in good health conditions. By means of an accelerometer placed on the hip, we recorded the acceleration values during the walk with and without fatigue. By means of the correlation of the strides, we measure its regularity. Our objective was to know how is affected the gait when a person is tired due to physical fatigue. We found that stride of human gait is affected when a person is fatigued. We conclude that physical fatigue can affect a person's normal gait.

Abstract Nonpuerperal uterine inversion is an extremely rare event. Of the small number of cases reported in the literature, most have been associated with benign uterine tumors and only a few with uterine sarcoma or carcinoma. To the best of our knowledge, no case associated with cervical carcinoma has been reported. In this paper, we report a rare case of nonpuerperal uterine inversion caused by an aborting fibroid and associated with squamous-cell carcinoma of the cervix in a 70-year-old postmenopausal woman. The patient was successfully treated surgically by excision of the fibroid vaginally, followed by a repositioning of the uterine inversion abdominally (the Haultain method) and total abdominal hysterectomy and bilateral salpingo-oopherectomy. Postoperative radiotherapy for cervical carcinoma was given after histopathologic confirmation. The association of malignancy with a nonpuerperal uterine inversion must be kept in mind and confirmed by histopathology. (J GYNECOL SURG 25:37)


Colicin E2 purified by conventional methods contains a tightly bound low-molecular-weight protein, as has been found with purified colicin E3 [Jakes, N. & Zinder, N. D. (1974) Proc. Nat. Acad. Sci. USA 71, 3380-33841. Such E2 preparations do not cause DNA cleavage in vitro. After separation from the low-molecular-weight protein, colicin E2 retained the original in vivo killing activity, and in addition showed a high activity in vitro in cleaving various DNA molecules, such as a ColE1 hybrid plasmid and DNAs from Escherichia coli, X phage, 4X174 phage, and simian virus 40. The low-molecular-weight protein ("E2-immunity protein") specifically prevented this in vitro DNA cleavage reaction, i.e., had an "immunity function." The results demonstrate that colicin E2 itself is a DNA endonuclease and explain the in vivo effects caused by E2 in sensitive cells as well as the mechanism of immunity in E2-colicinogenic cells. Colicin E2 (E2) is a protein antibiotic synthesized by certain strains of coliform bacteria that carry the ColE2 plasmid, and is classified in the E group of colicins along with colicins El and E3 (1, 2). Although the physical properties of E2 and E3 are similar (3) and both colicins share the same receptor (1, 2), their apparent mode of action is different. It was first discovered that E2 causes degradation of DNA, while colicin E3 (E3) causes specific inhibition of protein synthesis in sensitive Escherichia coli cells treated with these colicins (4). Subsequent work on the mode of action of E3 has demonstrated that ES inactivates ribosomes in treated cells (5) by causing the cleavage of a fragment from the 3' end of the 16S RNA (6, 7). The same cleavage reaction has also been demonstrated in vitro using "purified" E3 protein (see below) and purified ribosomes (8, 9). This in vitro demonstration of E3 action has strongly indicated that E3 acts directly on ribosomes rather than indirectly and that E3 itself is an RNase with a very stringent substrate specificity. In contrast to ES, the mechanism of action of E2 has not been clear. Since the initial discovery of DNA degradation in E2treated sensitive cells (4), several authors have confirmed and extended the original observations on DNA cleavage reactions (10-13). However, others have suggested that the primary action of E2 is not on the cellular DNA, but on some other targets such as membranes (14) or tRNA (15). Since E2 has properties similar to E3 (3), and E3 causes ribosome inactivation in vitro, one might expect some kind of effects of E2 on cellular DNA in vitro, if DNA is in fact the primary target of E2. Several attempts have been made to demonstrate such effects in vitro using purified E2 (e.g., refs. 16-19). However, published results were either negative or too uncertain to allow a definitive conclusion regarding such direct effects. Recently, Jakes and Zinder observed that the "purified" ES preparations obtained with the conventional purification methods (3) contained about one molar equivalent of the E3immunity protein (20). These authors demonstrated that the immunity protein could be separated from the E3 protein by preparative electrophoresis in sodium dodecyl sulfate/polyacrylamide gels and that E3 protein (called "ES*") free of immunity protein was much more active than the "complexed" ES preparation in ribosome inactivation in vitro (20). They also noted the presence of a small-molecular-weight protein in highly purified E2 preparations (cited in ref. 20). From the analogy of the colicin E3-immunity protein complex, they inferred that this small-molecular-weight protein is probably the E2-immunity protein. We have now succeeded in separating colicin E2 (called "E2*") from the low-molecular-weight protein and demonstrated that E2* thus obtained is highly active in degrading DNA in vitro and that the small-molecular-weight protein prevents this DNase activity, i.e., has an "immunity function." MATERIALS AND METHODS E. coli PR13, which lacks RNase I, was used as the colicinsensitive strain. Colicins E3 and E2 were purified from mitomycin-C-induced cultures of E. coli CA38 and W3110 (ColE2), respectively, according to the method described by Herschman and Helinski (3). The colicins obtained were still complexed with immunity proteins (cf. ref. 20). E3-immunity protein was previously purified by J. Sidikaro in this laboratory (21). Pure E2-immunity protein was obtained as described below. Colicin E2* was separated from the immunity protein by dissociation of the complexed E2 with guanidine-HCl at about 4°. Lyophilized E2 was dissolved in dissociation buffer (1 mg/ml). The dissociation buffer contained 6 M guanidine-HCl (Grade I, Sigma Chemical Co.), 0.2 M NaCl, 1 mM dithiothreitol, and sufficient 1 M K2HPO4 to adjust the pH to 6.8. After the incubation for 1 hr at 40, the solution was subjected to one of two methods to obtain a complete separation of E2* from the immunity protein. In the first method, the solution was applied to a Sephadex G-100 "superfine" column equilibrated with the dissociation buffer and the two proteins were separated. In the second method, the solution was filtered through a PM30 membrane (Amicon) using a 50 ml stirred cell. The protein left in the Amicon cell (E2*) was diluted with the dissociation buffer and the filtration process was repeated. After five such processes, the E2* preparation was diluted in a solution of 6 M urea and 0.2 M NaCl, concentrated again to about 2 mg/ml of protein, and dialyzed against 0.1 M sodium phosphate, pH 7.0, containing 0.2 M NaCI. The filtrate containing the E2-immunity protein was concentrated using a UM2 filter (Amicon) and treated in the same way as E2*. The proteins could be stored in the dialysis buffer at 40 in polypropylene tubes for at least 2 months without loss of in vivo or in vitro activity. Colicin ES* was prepared in a similar way. Colicin activity in vivo was determined by spot-testing dilutions of colicin in 10mM potassium phosphate containing Abbreviations: E2 and ES, colicins E2 and ES, respectively; Col, a colicinogenic plasmid; kb, kilobase (1000 base pairs); SV40, simian virus 40.


Recent work has shown that people can update their implicit evaluations based on facial trustworthiness. However, do these updated implicit evaluations map onto subsequent decisions? We examined whether implicit evaluations based on faces but updated in light of new behavioral evidence uniquely predict responses in the trust game. Across six studies (N = 2,059), we measured participants' initial implicit evaluations of a target based on the target's face and then their updated implicit evaluations based on newly learned behavioral evidence. We then tested whether these updated implicit evaluations uniquely predicted (i.e., beyond explicit evaluations) responses in a hypothetical trust game. Although participants consistently based their initial evaluations on the face and updated their evaluations after learning new diagnostic information, their updated implicit evaluations did not uniquely predict their responses in the trust game. We discuss theoretical considerations in this article.


This paper presents the results of an investigation of the ballistic limits and failure modes of AA2024-T351 sheets impacted by cubical projectiles. The effect of cube orientation on the ballistic limit and failure modes was considered in detail. Three impact configurations were investigated. Configuration one, two and three considered face, edge or corner impacts correspondingly. The experimental results were complemented with finite element analysis results in order to explain the observations. The lowest ballistic limit (202m/s) was observed when the cube edge impacted on the target. In the cube face impacts, the ballistic limit was higher (223m/s), and the highest ballistic limit (254m/s) was observed for the corner impact. Although the face impact did not have the lowest ballistic limit, this impact configuration resulted in the least amount of projectile energy loss for impacts above the ballistic limit. With the aid of finite element modelling, it was possible to develop a better understanding of the test results and explain that the observed differences in impact response were not just due to a difference in projectile frontal area, but also due to the combination of the localised deformation near the projectile impact point and the resulting global (dishing) deformation. © 2017 The Authors.

One of the first subjects introduced to students of environmental chemistry is the aqueous chemistry of aluminum. This metal is the third most abundant element in the shallow Earth, where it hydrolyzes in water to produce a rich array of solute molecules and solids, including clays and aluminum hydroxide phases. Although these materials are ubiquitous, we are just beginning to understand the kinetic properties of their surfaces at the molecular scale. The problem is experimental sthe solids are too unwieldy, even as colloids, for detailed spectroscopy. One recent approach has been to use 1 -2 nm aqueous Al(III) molecules as experimental models to determine reaction rates and pathways at a fundamental level. The 1 -2nm-sized clusters are useful because they expose functional groups that resemble those found on the minerals, yet reactions at these functional groups can be studied at the molecular scale using relatively simple methods of solution spectroscopy, such as NMR. The 1 -2 nm ions are sufficiently small that reactions can then be simulated at a high * E-mail: firstname.lastname@example.com. Phone: 530-752-3211.

Abstract : In an initial effort to assess environmental research in other countries, the author made selected visits to the United Kingdom, Federal Republic of Germany, the State of Israel, NATO, and the Commission of European Communities in Brussels, Belgium. Results of the author's visits are presented as specific environmental topics such as hydrocarbon bioremediation, groundwater treatment, ordnance demilitarization, marine antifouling control, pollution prevention, with reference to existing Navy requirements and research where relevant. The author points out that research and development has the potential for providing the leverage leading to processes that will achieve affordable cleanup of past, and prevent future environmental insult.


An examination of recent European Court of Justice case law indicates that certain forms of advertising campaigns by 'trade councils' and other producer group organizations which receive government support may be unlawful as a breach of the principle of 'free movement of goods' established by Article 30 of the Treaty of Rome. The implications of this ruling are studied in an attempt to determine the scope of future advertising by 'trade councils'. The paper concludes with a brief examination of the recent Council Directive 84/450, due to be incorporated into British law by 1 October 1986.


A trunking fitting 10 comprises an open connector having a flat base 13 and upright sides 11, 12 extending between at least two generally rectangular openings which lie in mutually inclined planes. The upright sides 11, 12 which together with the base 13 define each opening are not parallel to each other. A lid 22 is also provided and is adapted to close the connector and extends beyond the generally rectangular openings. The lid extensions 23,24 cover the joints between the connector and adjacent trunking sections 17,18 thereby preventing the ingress of dirt or infestation at the joints.


Combined fluorescence with absorbance technique, contrast fluorescence detection optical system used for microfluidic chips is proposed. By designing the optical parameters of the light splitting system and telecentric optical system, the system can be used for LIF and absorbance detection by tuning the working distance. To evaluate the performance of system, the MTF and spot are shown. Meanwhile, to further investigate the distribution of illumination, distribution of illumination on image plane and defocus plane are also calculated. These results may be helpful for designing a microfluidic detection system with improved sensitivity, enhanced detection efficiency, and lowered detection costs and is promising for offering a new method for spectrum scanning.


We have performed coherent probing of a strongly coupled quantum dot-photonic crystal cavity system, and employed this platform to demonstrate effects including controlled phase shift at the single photon level and photon blockade.


In this dissertation, the main objective is to analyse and investigate oral comprehension, the form of oral expression and the use of songs in the English classroom in the fourth year of Obligatory Secondary Education (ESO), in order to develop spoken oral skills. An informative society and new technologies have collectively put communicative skills into the spotlight, skills that are vital at the present time given that globalization is initiating deeps changes in society. Today, communication has become an increasingly important and key element, which requires educative practices to be adapted in order to accommodate these transformations. In this context, encouraging oral skills is fundamental and one wishes to discover whether focusing and developing them using songs would be beneficial or not.
Regarding the methodology, one will commence with a theoretical basis concerning oral skills and the use of songs in the English classroom based on bibliographical research. Thus, thereafter and continuing from the previous point, one will suggest a practical proposition that involves using songs, which is specifically designed to develop oral skills in the English teaching classroom of the fourth Year of Obligatory Secondary Education.
As the project developed, one has been able to confirm that the use of songs has great potential to develop oral skills in the classroom. It can be seen that they encourage the motivation of the student and they are a readily available and easily accessible resource, which are essential components in the task of teaching given that it greatly facilitates the teacher.


A method to reduce the noise radiated by a ribbed, aircraft panel excited by turbulent boundary layer flow is presented. To compute the structural-acoustic response, a modal approach based on finite element/boundary element analysis was coupled to a turbulent boundary flow forcing function. A static pressure load was also applied to the panel to simulate cabin pressurization during flight. The radiated sound power was then minimized by optimizing the horizontal and vertical rib location and rib cross section using an evolutionary search algorithm. Nearly 10 dB of reduction was achieved by pushing the ribs to the edge of the panel, thus lowering the modal amplitudes excited by the forcing function. A static constraint was then included in the procedure using a low-frequency dynamic calculation to approximate the static response. The constraint limited the amount of reduction that was achieved by the optimizer.


Reactive sputtering utilizing a dense and active electron-cyclotron-resonance (ECR) microwave plasma enabled us low-temperature and high rate deposition of Ni-Zn spinel ferrite thin-films using a metal sputtering target. In this study, to achieve higher rate deposition, a conic target was introduced to a ECR sputtering apparatus we have developed, instead of platelet targets used in our previous work. The Ni-Zn ferrite thin-films with a reasonable saturation magnetization of about 290 emu/cc and low coercivity of about 11 Oe could be deposited at an increased deposition rate of 44 nm/min. Also, superior thickness uniformity was confirmed in the substrate area of 140 mm in diameter.


Physical accuracy, numerical stability, and computational speed are critical factors in the simulation of collisions. The impulse‐based method models collisions in a system of rigid bodies in a relatively reliable and fast manner. In the present paper, evidence is presented for the energy‐conserving and momentum‐conserving properties of the method. Two different impulse‐based approaches are validated using numerical tests. A necessary condition is proposed for the impulse‐based method to be energy conservative. Results indicate that the impulse‐based method for collision simulation, which satisfies the proposed condition, is energy conservative. Copyright © 2013 John Wiley & Sons, Ltd.


Measurements of propagation loss for the leaky surface acoustic wave on (100)‐cut GaAs with 〈110〉 propagation direction are reported. The measurements were made in the frequency range 200–900 MHz. The propagation loss was determined with a novel technique using a delay line with four interdigital transducers. The effect of a hydrogen implant of dose 1014 cm−2 and energy 120 keV (technique for producing high resistivity isolation regions in GaAs) on propagation loss and macroscopic piezoelecticity are reported.

The yield was 83% as refluxing for 53min.


Abstract Basic principles of hyrogen-bonding are reviewed including cooperative effects and within the novel class of inclusion compounds formed by N,N′-ditosyl-p-phenylenediamine as a capable host, four aggregates with the hydrogen donor or acceptor guest molecules morpholine, pyridine, N,N-dimethylformamide and dimethylsulfoxide are reported. Morpholine introduces three additional hydrogen bonds N-H···N, N-H···O as well as C-H···O and pyridine, DMF and DMSO each one of type N-H···N, N-H··O(=C) and N-H···O(=S ). Crystallization and structures determined are discussed in detail with special emphasis on the varying sulfonamide conformation as well as on cavity or channel inclusion of the guest molecules. In conclusion, the crystal growth conditions and the structures of the altogether 13 N,N′-ditosyl-p-phenylenediamine inclusion compounds investigated are reviewed and possible reasons for their formation are discussed.


Human error has been implicated in almost 70–80% of civil and military aviation accidents. It appears that attempts to understand human factors in aircraft accidents and apply remedial strategies have been made in isolation in addressing a particular link in the whole process of aircraft accident prevention. The suggested holistic approach to minimize aircraft accidents, aims to provide a composite and macroscopic view of the activities within the aviation environment that can be targeted to produce the desired results. It also provides a microscopic look at possible domains within each link. Targeting one particular aspect or link in the entire process may or may not influence the other components in the loop. Such an approach would address the experience and certainty of safety investigators with regards to contribution of human factors in aircraft accidents and the understanding of temporal relation between various human factors at one end to issues of intervention strategies based on sound human factors principles and a follow up evaluation of the impact of these intervention strategies on the other end. The influence of safety culture in integrating the diverse components of the accident prevention program is highlighted.


Vacancies are known often to be the dominant type of point defects in perovskite oxides, but their presence can rarely be directly determined. Positron annihilation methods have unique sensitivity to vacancy-related defects and the variable energy positron beam (VEPB) techniques allow near-surface depth profiling. The characterization of strontium titanate (SrTiO3) thin films, deposited on SrTiO3 substrates by pulsed laser deposition, using Doppler broadening of the annihilation radiation detected VEPB measurements, is reported. The laser repetition rate and the postgrowth anneal conditions for the samples were varied. VEPB measurements clearly detected the deposited SrTiO3 layer (the increase in the Doppler broadened line shape parameter S compared to the substrate was ∼3.5%) and showed the presence of a high concentration of open volume defects. The magnitude of the change in S and the lack of dependence on anneal oxygen partial pressure provided evidence that strontium vacancies and VSr-oxygen vacancy ...


Abstract—In the present paper, an attempt has been made to estimate seismic hazard at bedrock level in terms of PGA using state of art probabilistic seismic hazard analysis. A detailed catalogue of historical and recent seismicity within 300 km radius around the city has been compiled and new seismotectonic map has been generated for the region. The completeness of the data should be checked before carrying out hazard analysis. Finally earthquake data was analyzed statistically and the seismicity of the region around District Headquarter Dantewara of Chhattisgarh, India, has been evaluated by defining ̳a' and ̳b' parameters of GutenbergRichter recurrence relationship. The Regional Recurrence Relationship and ―b‖ value, 0.6974 is obtained for District Headquarter Dantewara. The Maximum value of Peak Ground Acceleration (P.G.A.) for recurrence period of 100 years was found to be due to the Godavari Valley Fault which came out to be equal to 0.06211 for 50 Percentile and 09887 for 84 Percentile. The seismic hazard curve prepared, for district Headquarter can be furthered used to find out the PGA values for various return periods for different probabilities (2%, 10%, 50% ) of occurrence .


Uveal melanoma (UM), arising from melanocytes which reside in the uveal tract, is the most common primary intraocular tumor in adults. Despite successful treatment of the primary lesion by proton therapy or enucleation, up to 50% of UM patients develop metastases, predominantly in the liver. At present, there are no effective systemic treatments for metastatic UM, 80% of patients will die within 1 year after diagnosis of the metastases. Therefore, better understanding of the UM disease is urgently needed for successful development of effective therapies. UMs display a mutational status distinct from cutaneous melanoma types, having in 97.5% of the cases driver mutations in GNAQ or its paralogue GNA11 (GNAQ/11) that result in constitutive activation of the Gαq or Gα11 subunits, and less common mutations in CYSLTR2, and PLCβ4. Prior studies showed that oncogenic GNAQ/11 engages the PLCβPKC axis to stimulate the MAPK/ ERK signaling pathway (Chen et al., 2014). Downstream oncogenic GNAQ/11, a PLCβindependent TRIORhoAFAKYAP has been reported as another significant axis in UM cell progression (Feng et al., 2019). To characterize the intersection and importance of these different circuits downstream of oncogenic GNAQ/11, Chen and coworkers used a combination of pharmacologic and molecular genetic perturbations. In essence, the authors demonstrate that oncogenic GNAQ/11 stimulates the PLCβPKC axis, whose signal then branches into the MEKERK and FAKYAP pathways (Ma et al., 2021). It is worth noting that the authors also uncover differences in GNAQ/11 effects on these signaling that need to be further studied (Ma et al., 2021). Another twist in this study comes from the fact that genetic or pharmacological YAP inhibition has no significant effect on survival or colony formation ability of UM cells harboring oncogenic GNAQ/11 mutations (Ma et al., 2021), while FAK inhibition has only slight effects. Furthermore, YAP was mainly detected in the cytosol of the UM cells tested. These observations thereby indicate that the FAK/YAP element does not prevail in UM cell proliferation and survival. Supporting this conclusion analysis of the UM TCGA dataset did not point out to induction of YAP target genes, arguing against its active role in UM progression (Ma et al., 2021). Likewise, another recent study indicates that YAP activity is not associated with tumor sizes, metastatic status and the prognosis of UM patients (Kim et al., 2020). This is in contrast to mesothelioma cells, where YAP signaling is frequently activated and associated with poor prognosis (TCGA mesothelioma dataset) and which inhibition dramatically reduces mesothelioma cell survival (Kim et al., 2020). Hence, two recent reports show that YAP may have limited cellautonomous effect in UM cell proliferation and survival as compared to the MAPK/ERK signaling pathway. Nevertheless, a recent singlecell RNAseq study pointed out to a possible RHO/ RAC pathway activation in a subset of primary UM cells prone to metastasize (Pandiani et al., 2021). Combination of PKC and MEK inhibitors strongly reduced viability of mutant GNAQ/11 UM cell lines compared to combination of PKC and FAK inhibitors or FAK and MEK inhibitors (Ma et al., 2021). Compared to single drug formulations, only combination of PKC and MEK inhibitors have been reported to translate into meaningful antitumor responses, presumably due to feedbackmediated pathway reactivation in vivo (Chen et al., 2014). Furthermore, MEK inhibitors, in combination with dacarbazine looked promising in the phase 2, but not in the phase 3, clinical trial for UM patients (NCT01974752). Collectively, these findings strengthen the critical role of the PKCERK module in UM cell proliferation and survival. A phase Ib/II, multicenter study investigated the combined use of binimetinib (MEK inhibitor) and PKC inhibitor sotrastaurin (NCT01801358). However, this trial failed to show improvement in progressionfree survival of patients with UM. Another PKC inhibitor undergoes clinical trials in combination with binimetinib (NCT03947385). Given that the PKC family consists of three subgroups of enzymes (classical, novel, and atypical) with different requirement for diacylglycerol and calcium ion, one cannot rule out that effective therapeutic effect may be reached with drug combination targeting MEK and specific subsets of PKC such as the classical or novel isoforms. In keeping with this, in UM cells, MAPK activation has been shown to rely on classical and novel PKC.


We estimate the variance parameter of a stationary simulation-generated process using "folded" versions of standardized time series area estimators. Asymptotically as the sample size increases, different folding levels yield unbiased estimators that are independent scaled chi-squared variates, each with one degree of freedom. This result is exploited to formulate improved variance estimators based on the combination of multiple levels as well as the use of batching. The improved estimators preserve the asymptotic bias properties of their predecessors, but have substantially lower asymptotic variances. The performance of the new variance estimators is demonstrated in a first-order autoregressive process with autoregressive parameter 0.9 and in the queue-waiting-time process for an M/M/1 queue with server utilization 0.8.

Abstract Viewing all children as active participants in their own learning is central to inclusion. That children with atypical development experience a level of belonging that enables this in mainstream early childhood education and care (ECEC) settings remains a topic of hot debate and very much an unmet goal across the sector. Children with autism spectrum disorder (ASD), in particular, face significant challenges in ECEC settings, their educators continually seeking solutions for greater support. Given the escalating demand on mainstream ECEC settings to include these children, it was important to identify the specific supports needed by educators to achieve this with confidence and competence. This study investigated the outcomes of applying an evidence-based model of intervention to mainstream services via a targeted professional development program. Results of the study found that the benefits of engagement with mainstream ECEC settings extended beyond child outcomes to educators who were supported to develop the knowledge, understanding, and strategies to engage and teach children with ASD and manage their behaviours.


We study the implications of R-parity-violating () Minimal Supersymmetric Standard Model (MSSM) in lepton polarization asymmetry (ALP) in B→l+l- decays. The analysis shows that the ALP is significant only in a certain phenomenological parametric region of Yukawa coupling products and branching fraction. The analysis further shows how tanβ arising from type-II Higgs Doublet Model (2HDM) is constrained in the presence of Yukawa interactions.


A metric space $\mathcal{T}$ is a \emph{real tree} if for any pair of points $x, y \in \mathcal{T}$ all topological embeddings $\sigma$ of the segment $[0,1]$ into $\mathcal{T}$, such that $\sigma (0)=x$ and $\sigma (1)=y$, have the same image (which is then a geodesic segment from $x$ to $y$). A \emph{signed graph} is a graph where each edge has a positive or negative sign. The \emph{Sitting Closer to Friends than Enemies} problem in trees has a signed graph $S$ as an input. The purpose is to determine if there exists an injective mapping (called \emph{valid distance drawing}) from $V(S)$ to the points of a real tree such that, for every $u \in V(S)$, for every positive neighbor $v$ of $u$, and negative neighbor $w$ of $u$, the distance between $v$ and $u$ is smaller than the distance between $w$ and $u$. In this work, we show that a complete signed graph has a valid distance drawing in a real tree if and only if its subgraph composed of all (and only) its positive edges has an intersection representation by unit balls in a real tree. Besides, as an instrumental result, we show that a graph has an intersection representation by unit balls in a real tree if and only if it has an intersection representation by proper balls, and if and only if it has an intersection representation by arbitrary balls in a real tree.


IN the United States and Canada there are comparatively few cases of echinococcosis in man. Less than 2 per cent of these are found to involve the bones. Because of this rarity few roentgenologists ever see a case and hence do not suspect its presence when one occurs in their practice. As a correct pre-operative diagnosis is of great help in planning the operative procedure and as the roentgenogram can help in the diagnosis, it is important that roentgenologists be able to recognize the condition. The Taenia echinococcus is a small flatworm with two separate stages in its life cycle. As a sexually mature worm it lives in the small intestine of the dog. In man and some animals, such as sheep, cattle, and swine, it passes through the bladder-worm or cyst stage. The Taenia eggs are generally believed to enter man by way of the mouth. In the stomach the capsule is dissolved and the small embryo set free. The usual course from here is into the portal vein and thence to the liver. This accounts for the great prep...


This study aims to improve student learning outcomes and motivation by using the problem-based learning (PBL) model in theme VI, sub-theme 2 class IV of SD Negeri Banjarsari Samigaluh for the 2021/2022 academic year.

In cycle I to cycle II it is known that the learning outcomes of students have increased by 36.50%. As for the observational data on students' learning motivation objects also showed a significant increase, where in cycle I an average value was obtained of 3.6 with a percentage of 71.19% and in cycle II an average value was obtained of 4.3 with a percentage of 85.20%. This shows that from cycle I to cycle II, students' learning motivation increased by 14.01%. Therefore, it can be concluded that the application of the problem-based learning (PBL) learning model to theme VI, sub-theme 2 can improve the learning outcomes and motivation of fourth-grade students at SD Negeri Banjarsari Samigaluh in the 2021/2022 academic year.


An efficient Software/Hardware platform to execute more number of programs the internal circuitry flow is considered. The data can be of bits-number of times the bits arriving with different time intervals. In this paper we illustrate about the compressed test data from the embedded cores in a system on a chip varies significantly during the testing process. A novel scheme has been implemented for compressed system on a chip testing based on time-multiplexing for the channels. Some /more of the channels can be introduced which can enable the sharing the data channels, on which the compressed seeds are passed to every embedded core(individual cores). The channels can be fewer/larger based on the amount of testing channels available. The uses of modular and scalable hardware for on-chip test control and test data compression have been used. We define an algorithmic model for test data compression that is applicable to system-on-chip devices comprising intellectual property-protected blocks.


extensive fieldwork, which is reflected in the richly nuanced accounts of local strategies and responses to changes in land tenure. By focusing on the role of local elites, the diverse chapters manage to speak to one another, bringing in sharp relief the interplay between regulatory regimes, institutions, and local and national strategies. While the volume cannot provide a comprehensive investigation of all aspects of land politics throughout the Great Lakes, it succeeds in providing compelling case study accounts of how local politics, power, ethnicity and violence affect accumulation and dispossession, and the resulting impact on local livelihoods. A further analysis of the gendered impact of land policies and strategies would have been welcomed. With the exception of the chapter by van Leeuwen et al. on Uganda, the gender dimension of land politics was not discussed, but would have enriched an already excellent volume. Development practitioners and policymakers as well as Africanist scholars and researchers will find this volume to be enormously helpful, with its trenchant analysis of particular cases and insightful general conclusions. There is plenty of material for reflection and hopefully the volume will serve as a springboard for further work. Several chapters as well as the conclusion point to the need for pro-smallholder policies and pro-poor development, but the power dynamics uncovered by many of the chapters show why this is so difficult. Is it possible to overcome these dynamics? The volume's findings point to the need for further detailed analysis of specific mechanisms to strengthen the voice and agency of smallholders. The volume goes a long way in helping us understand the opportunities and constraints for local livelihoods in diverse contexts in the Great Lakes.


The stability and dynamics of synapses rely on tight regulation of the synaptic proteome. Shank proteins, encoded by the three genes Shank1, Shank2 and Shank3 are scaffold molecules in the postsynaptic density of excitatory neurons that contribute to activity-dependent neuronal signalling. Mutations in the Shank genes are associated with neurological diseases. Using state-of-the-art technologies, we investigated the levels of expression of the Shank family messenger RNAs (mRNAs) within the synaptic neuropil of the rat hippocampus. We detected all three Shank transcripts in the neuropil of CA1 pyramidal neurons. We found Shank1 to be the most abundantly expressed among the three Shank mRNA homologues. We also examined the turnover of Shank mRNAs and predict the half-lives of Shank1, Shank2 and Shank3 mRNAs to be 18–28 h. Using 3′-end sequencing, we identified novel 3′ ends for the Shank1 and Shank2 3′ untranslated regions (3′ UTRs) that may contribute to the diversity of alternative polyadenylation (APA) for the Shank transcripts. Our findings consolidate the view that the Shank molecules play a central role at the postsynaptic density. This study may shed light on synaptopathologies associated with disruption of local protein synthesis, perhaps linked to mutations in mRNA 3′ UTRs or inappropriate 3′ end processing.


The fundamental problem in high speed communication is that it suffers a lot of signal integrity issues due to dispersion (caused by dielectric variation with angular frequency), reflection (S11) , and insertion losses (S12) of the channel made of copper. When a pulse width τ with magnitude V0 is driven through a lossy channel, we observe a reduction in magnitude (due to S12 and S11) and an increase in pulse width (due to dispersion). It causes different values of skin effect and dielectric loss leading to different effective resistance at each segment as the pulse moves through the channel. This impedance mismatch generates reflection noise, which makes the identification of the received signal difficult at the receiver. Modeling of such a complex situation and reconstruction of a high speed signal driven through a lossy channel remain an open problem for the research community. This work unveils a method of designing a system that can renovate a square wave pulse of 40 ps or less (corresponding to a data rate of 25 Gbit/s or more) after sending the same over a lossy channel from transmitter to receiver. The received noisy signal (Signal-A) is sent through a RC circuit to obtain a different delayed signal (Signal-B). Both the signals are then applied to the two terminals of a comparator. The difference, ∆(t), between Signal-A and Signal-B is measured and it is witnessed that the voltage difference (φ) of two consecutive maximum peaks of ∆(t) actually provides us with a better way to determine the design criteria of threshold voltage, VT , of the comparator for the reconstruction of the square pulse. It helps to eliminate the needless oscillations at the output of the comparator. The design of a threshold voltage depends fully on the channel properties.


In this dissertation I examine whether OLAF's composite enforcement procedures can result in violations of the person concerned's fundamental rights and, if so, how the OLAF and national frameworks must be adjusted to prevent such violations?

OLAF is the European Union's anti-fraud office. OLAF's mission is to fight fraud, corruption and any other illegal activity that affects the financial interests of the Union. To that end, OLAF carries out administrative investigations, where it gathers evidence itself, and coordination cases, where OLAF coordinates the Member States' investigations. OLAF's investigation and coordination cases are conceived of as mere derivatives of other more traditional forms of law enforcement cooperation in which authorities enter into obligations to cooperate with one another, but each acts to fulfill these obligations within its own separately identifiable legal order on the basis of its own law. This system, in its most conventional form, is founded on the notion of territorial sovereignty. If we extend the logic of this approach from enforcement (the 'sword') to fundamental rights (the 'shield'), issues in relation to the latter – and the accompanying responsibility to prevent and/or remedy them – can arise only in individual (sovereign) legal orders. The way in which we appreciate OLAF, as an evolved cognate of traditional forms of law enforcement cooperation, therefore directly dictates which, and the way in which, fundamental rights issues enter into the equation.

In this dissertation I pitch a new contrasting way of looking at OLAF: so-called 'composite enforcement procedures'. In these types of procedures, responsibilities for the entirety of enforcement are attributed to the inextricably linked European Union and Member State legal orders. If we stare at OLAF through this new looking glass, which I think we should do, other fundamental rights issues can step into the fore that would otherwise go unnoticed. These are issues that come about not in single legal orders, but rather exist in between or among the EU and the Member States. The goal this dissertation sets out to achieve then is to find out whether such fundamental rights problems indeed exist and, naturally, how they can be resolved. I do so by considering the 'person concerned': the natural or legal person who is the subject of an OLAF investigation or coordination case. At the end of this dissertation I assess whether, and if so how, the fundamental rights problems identified for OLAF also manifest themselves in criminal cases under the lead of the European Public Prosecutor's Office.


We obtain the equations that define the equilibrium of a homogeneous relativistic gas of neutrons, protons and electrons in a constant magnetic field as applied to the conditions that probably occur near the center of neutron stars. We compute the relative densities of the particles at equilibrium and the Fermi momentum of electrons in the strong magnetic field as function of the density of neutrons and the magnetic field induction. Novel features are revealed as to the ratio of the number of protons to the number of neutrons at equilibrium in the presence of large magnetic fields.


Survival of ACI rat heart grafts in Lewis rat (LEW) recipients treated with a short course of 15‐deoxyspergualin (DSG), in a dose of 5 mg/kg daily beginning from day 4 of grafting, was markedly prolonged, with a mean survival time of 29.8 ± 3.0 days. On day 20 after grafting, the cellular mechanism of inducing allograft survival after DSG treatment was analyzed by testing the activation of spleen cells in several assay systems. The results indicate that spleen cells from DSG‐treated rats with surviving heart allografts show almost no proliferative response against donor strain stimulator cells in the mixed lymphocyte reaction (MLR) as compared with controls. Their cytotoxic activity was lower than that of spleen cells from rats with heart allograft rejection towards donor strain target cells. Adding various concentrations of spleen cells from DSG‐treated LEW rats with surviving ACI heart allografts to the MLR when the responder cells from normal LEW rats were exposed to irradiated ACI or Wistar (third party) stimulator cells revealed a strong suppression, in a cell‐dose‐dependent manner. Moreover, the transfer of 2.0 × 108 spleen cells from DSG‐treated LEW rats with surviving ACI heart allografts to an irradiated grafted host did not prolong the survival either of the ACI heart grafts or of the third party Wistar heart grafts. These results suggest that the proliferative response and cytotoxic activity are lowered and suppressor cells are induced by treatment with DSG, in rats with surviving allografts.


The present invention provides an event processing method in multiple systems. The method is applied to a terminal device operating environment comprising a master control system and at least two subsystems. The method comprises: detecting to-be-processed event information from any subsystem, and sending the to-be-processed event information to the master control system; and based on an event processing mode matched with the to-be-processed event information, controlling the to-be-processed event information by the master control system. According to the event processing method in multiple systems, provided by the present invention, the event processing problem in multiple systems is solved; shared events of the subsystems are unitedly uploaded to the master control system and unitedly processed by the master control system, instead of each subsystem processing respective event, so that it can be ensured that event processing of the subsystems is unified in style and the system in a foreground can be informed in time by the to-be-processed event information of each system in a background; and the user can process a corresponding event in time to avoid missing the processing of significant events, and a high-security demand of user data is met.


A closed-form analytical model for the spatiotemporal processes giving rise to soliton pulse formation and compression in an additive-pulse mode-locked coupled-cavity fiber laser systems is presented. The model is based on a modified nonlinear Schrodinger equation for solitons. Perturbation techniques coupled with Fourier transform methods are employed to simplify the solution to the nonlinear Schrodinger equation. The contributions of Gaussian white noise, random noise, group velocity dispersion, and self-phase modulation to the mode-locking process and system performance are described. The model is used to analyze the temporal and spectral characteristics of a 1.55-µm mode-locked soliton fiber laser with a pulse width of 25 ps and a pulse repetition rate of 4 ns, accurately.


During the past 6 years, I have had the opportunity to work with a wide range of projects. Our HUBzero software platform currently powers nanoHUB.org and 25 other Websites or ''hubs'' used for both research and education (McLennan and Kennell, 2010). These hubs support many different areas of science and engineering, including nanotechnology, microelectromechanical systems, cancer care, bio-fuels, earthquake engineering, volcanic activity, pharmaceutical engineering, environmental modeling, battery technology for electric vehicles, and heat transfer applications. All together, these Websites have served more than 390,000 unique visitors during the past 12 months. Through our experiences with these projects, we have found at least two different approaches for managing data. Researchers use unstructured data, such as project notes held in a wiki, collections of PowerPoint files and reports, program code, and other text files to represent data for their projects. Unstructured data are usually stored on a local desktop or may be managed by facilities such as Confluence, SharePoint, Google Groups, and Dropbox. HUBzero supports aspects of all of these facilities. Within a hub, users can create private groups and invite other users to join. In this mode, a professor may work together with his graduate students, or undergraduate students may work together on a class project, or colleagues may work together to develop a research proposal. Users leverage a collaborative wiki for project notes, a discussion forum, and a Subversion repository for editing/versioning of source code, experimental results, and other project data. The data kept within these projects are available only to members allowed to join the group. Data sets, summaries, and other products shaped within this private space may be published as desired and made available to the general public under Creative Commons and other license terms. Researchers also share structured data, such as spreadsheets, protein databank files, satellite images, and telescope data. A few hubs have begun to develop relational databases coupled with tools for data mining within HUBzero. For example, the Cancer Care Engineering project at cceHUB.org has created a database for tracking blood samples, clinical patient data, and related proteomics and metabolomics datasets. Researchers at the IU School of Medicine collect the blood samples and upload patient data using forms such as the one shown in Figure 1. Other researchers mine the data by applying statistical analysis tools within the hub environment. This facility was created in such a way that it can be quickly customized and transferred to other projects. Recently, the same code was used to create a thermal properties database on thermalHUB .org. Similar code is being developed to support earthquake engineering data for the nees.org project. Perhaps the most compelling feature of HUBzero is the way it helps researchers create and publish interactive simulation tools, along with seminars, tutorials, teaching materials, and other supporting resources—all in a way that can be accessed via an ordinary Web browser. New tools can be constructed in a matter of hours using HUBzero's Rappture toolkit, as shown in Figure 2. Developers start by building a description of the inputs/ outputs for their tool. In the past, this has been done by coding the description directly in an XML document, but the new ''Instant Rappture'' builder makes this process even easier for domain scientists. Researchers drag items from a palette of objects into their tool description, specify labels, units of measure, and other semantic information for each object, then save the resulting description in a file named tool.xml. A user launches the tool, and Rappture reads the XML description and renders a graphical interface with controls for the various input elements. The user sets parameter values and presses the Simulate button. Rappture then executes the underlying simulation code, which may run on the same local machine, or be sent to a cluster or another Grid resource for computation. Once the simulation has finished, Rappture loads the results into the GUI so the user can visualize them and explore them. Rappture captures provenance about the simulation run, including who ran the simulation, when it was run, what machine computed the result, and even when the tool was compiled/installed and the precise revision number from the source code control system. Rappture contains application programming interfaces (APIs) for C/Cþþ, Fortran, MATLAB, Python, Perl, Ruby, Tcl, and Java, so researchers can add a Rappture GUI to a wide variety of existing codes and continue to work with their favorite programming language. Rappture can be used to drive simulators written with MPI and other parallelization libraries, and it can send simulations off to remote execution hosts


The effect of hypophysectomy on somatostatin (SRIF) content in the rat pancreas was investigated. SRIF content was determined by the specific radioimmunoassay developed by us.Four weeks after hypophysectomy, the total SRIF content in the rat pancreas had not changed or decreased, but the content per mg wet weight as well as per mg protein had increased markedly and the content of islets obtained by collagenase digestion had showed a tendency to increase. The mechanism and the pathophysiological significance responsible for these changes remain to be determined, so further examination of this problem will be necessary.


We show that the standard evolution of radiation-dominated era (RDE) universe a ∝ t 1 / 2 is a sufficient condition to solve a sixth order gravitational field equation derived from the Lagrangian containing BR ab R ab + CRR ; cc as well as a polynomial f ( R ) for a spatially flat radiation FLRW universe. By virtue of the similarity between R ab R ab and R 2 models up to the background order and of the vanishing property of R ; cc for H = 1 / (2 t ), the analytical solution can be obtained from a special case to general one. This actually proves that, even within modified gravitational theory involving higher-order terms, the standard cosmic evolution is valid in Einstein gravity with the higher-order terms, which are generally expected to have small impacts. An application of this background solution to the tensor-type perturbation reduces the complicated equation to the standard second order equation of gravitational wave.


The main purpose of this paper is to investigate the effects of KM infrastructure on knowledge sharing and KM performance. Knowledge sharing is the center of KM, so we take knowledge sharing as a mediator variable in the impact of KM infrastructure on KM performance .Based on the survey of enterprises from IT and software industry in Pearl River Delta, this paper examined the relationship between KM infrastructure, knowledge sharing and KM performance. The results revealed that KM infrastructure positively and significantly influenced the knowledge sharing, and knowledge sharing was an important mediator between KM infrastructures and KM performance.


Spectrally resolved streak camera measurements of picosecond pulses emitted by hybridly colliding pulse mode-locked (CPM) laser diodes are presented in this letter. Depending on the modulation frequency both blue-chirped (upchirped) and red-chirped (downchirped) pulses can be observed. The two different regimes and the transition between them are characterized experimentally and the behavior is explained on the basis of our model for the CPM laser dynamics.


June 2016 O ne of the most common complaints of adults visiting an audiology clinic is difficulty in understanding speech in the presence of background noise. Performance in noise is often attributed to sensorineural hearing loss. However, there are many individuals with normal hearing who report difficulty hearing in background noise, which demonstrates how inadequate a typical audiometric evaluation is in evaluating the demands of speech comprehension in complex listening situations. It is also unclear which anatomical structures are responsible for our performance in background noise. Discovering the roles of inner hair cells (IHCs), outer hair cells (OHCs), and auditory neurons in speech understanding in quiet and in the presence of background noise is currently a hot topic in the scientific community. Previous studies have suggested that the eighth cranial nerve, or Auditory Nerve (AN), may play a role in speech understanding in the presence of background noise. In Temporary Threshold Shift (TTS) studies in animals (Kujawa. J Neurosci 2009;29:14077-85), noise exposure has been shown to cause temporary damage to OHCs (as measured by Distortion Product Otoacoustic Emissions [DP-OAEs]) and permanent damage to the AN (measured by a decrease in the wave I amplitude of the Auditory Brainstem Response [ABR]). The authors of these studies speculate that a decrease in AN activity would affect speech in noise performance (Furman. J Neurophysiol 2013;110:577-86). However, measuring speech in noise among humans is a difficult task. Our group recently presented preliminary data in this realm at the 2016 annual meetings of the Association for Research in Otolaryngology, the American Auditory Society, and the American Academy of Audiology. The aim of our study was to investigate the roles that OHCs and the AN play in audition in quiet and performance in noise. Participants included 40 English speaking adults (mean 45 years old) recruited from our audiology clinic. All subjects underwent an audiological evaluation that included tympanometry, air and bone conduction thresholds, speech reception thresholds (SRT), and word recognition in quiet (WR-Q) using recorded NU6 word lists. These measures were performed for a single ear and stimuli were presented at 0, 10, 20, and 40 dB SL to control for hearing loss. OHC function was evaluated by measuring DP-OAE amplitudes and thresholds. AN function was measured by the amplitude, latency, and threshold of wave I of the ABR. Our preliminary findings revealed that those who exhibited better word recognition in noise were younger people with better hearing, more robust OHC function (both DPOAE amplitude and DPAOE threshold), and longer spiral ganglion absolute latencies and higher thresholds. Unlike animal studies, wave I amplitude failed to be a reliable metric of AN function in humans (ABR amplitudes are known to be notoriously variable in awake human subjects). Rather, AN latency and threshold produced repeatable measurements of AN function. However, our preliminary results of AN function were not what we had expected. We found that people who performed poorer in background noise exhibited a shorter wave I latency and a lower wave I threshold, which on the surface was the opposite of what we expected based on animal models. However, this discrepancy is likely due to the dysfunction of the tuning properties of the OHCs and AN. In the aforementioned animal models, the experimental model exhibited OHC function but a decrease in wave I amplitude. Therefore, it appears that normal OHC function is required for the expected lower wave I amplitude that would also exhibit a longer wave I latency and higher wave I threshold. In our current study, both OHCs and AN were abnormal in persons exhibiting poorer performance in background noise. Based on other animal studies, OHC damage should result in a decrease in wave I latency and a lowering of Outer Hair Cell Damage: A Completely Different Listening Experience

The contradiction requirements of seismic migration for the computation efficiency, divergence feature, imaging angle and suitable velocity distribution promote the research and application of the wavefield extrapolation algorithm. Based on the different algorithms and their characteristics, an implementation of migration by second wavefield extrapolation and common time-shift matrix is presented with improved efficiency under the same imaging performance. On side of the wavefield extrapolation, a Fourier finite difference extrapolation with long stride in depth is adopted to downward continution, in this way, the computation is saved and the divergence feature and the velocity changing behavior in lateral and vertical at high imaging angle is kept. As a result, a full wavefield in its right position at each depth of long stride is acquired. Asecondary migration is made by normal depth step finite difference method within each stride, and the wavefield is repositioned based on last wavefield between two depths. On side of wavefield imaging, the calculation of trigonometrical function, is taken to get 25%~45% reduction of the computation at the cost of a little EMS memory under the same precision.


Intraalveolar fibrin deposition is a prominent histologic feature of neonatal respiratory distress syndrome (RDS). We hypothesized that in infants in whom RDS progresses into CLD, chronic inflammation of the airway would derarrange alveolar-capillary integrity and lead to prolonged fibrin deposition in the alveolar spaces. To test this hypothesis, we determined concentrations of inflammatory cells (neutrophils,N, and macrophages, M,) and products of fibrin turnover (D-dimers) in the bronchoalveolar lavage (BAL) fluid of infants who initially had RDS and developed CLD than infants who had uncomplicated RDS. Methods: twenty-three preterm infants who required mechanical ventilation because of RDS underwent BAL on day 1 of life and thereafter every other day during endotracheal intubation. The samples collected on dexamethasone admninistration were not included. After cell counts were made, BAL fluids were centrifuged and D-dimers measured (ELISA).Results: Fourteen patients (EG: 27wks±2, BW:805g±187) developed CLD (02≥28 days) and 9 did not (EG:28wks±2, BW: 899g±166). Median values ± SD of N and D-dimers are shown below. M counts did not statistically differ between the two groups of infants.*p<0.05 Table


Summary: Communication is one of the most important factor for success in organisational world. There is a re- search gap which we would like to address in this paper: lack of research on communication practice in social enterprises. The main research question we would like to investigate in the paper is: what kind of communication we can find in these organisations. One of our research goals was to find out factors which are critical in the process of communications social enterprises. Also, we wanted to understand what kind of communication tools are used and what changes the management practice and public image of social enterprises in Poland. This paper is drawn on set of qualitative data from broader research on social economy sector conducted in Poland in period 2011-2013. For the purpose of this paper we have conducted multiple case study analysis and analysed 28 case studies of existing social enterprises. The research proved that ways of communications are developing with organisational culture; organisational behaviour and communication processes are beginning to resemble more non-governmental organisations than commercial ones. A direct, horizontal and informal communication prevail in Polish social enterprises.
