Design and Development of Denim Fabrics with Improved Strength and Impact Abrasion Resistance for Motorcyclist Clothing

This study aims to design and develop denim fabrics with enhanced mechanical and impact abrasion resistance performance using different materials, yarn types and fabric constructions. It was aimed to reach the standard impact abrasion resistance requirements of motorcycle protective clothing for Level 1 in high impact areas of the body (zones 1 and 2), such as hip and knee areas. The existence of cotton/Cordura® yarn in warp and T400 polyester yarn in the weft and the use of higher yarn densities increased the performance in tensile strength and impact abrasion resistance, compared to a classical cotton denim fabric. The use of coarser yarns and fabrics with a double weave construction increased impact abrasion resistance compared to single layer cloths. The double and backed cloth samples developed with cotton/Cordura® and Kevlar®/polyester yarns in their construction showed impact abrasion resistance times over 4 s and reached the “EN 13595-2:2002 Level 1 abrasion resistance” standard requirement.

Agreement attraction in native and nonnative speakers of German

ABSTRACTSecond language speakers often struggle to apply grammatical constraints such as subject–verb agreement. One hypothesis for this difficulty is that it results from problems suppressing syntactically unlicensed constituents in working memory. We investigated which properties of these constituents make them more likely to elicit errors: their grammatical distance to the subject head or their linear distance to the verb. We used double modifier constructions (e.g., the smell of the stables of the farmers), where the errors of native speakers are modulated by the linguistic relationships between the nouns in the subject phrase: second plural nouns, which are syntactically and semantically closer to the subject head, elicit more errors than third plural nouns, which are linearly closer to the verb (2nd-3rd-noun asymmetry). In order to dissociate between grammatical and linear distance, we compared embedded and coordinated modifiers, which were linearly identical but differed in grammatical distance. Using an attraction paradigm, we showed that German native speakers and proficient Russian speakers of German exhibited similar attraction rates and that their errors displayed a 2nd-3rd-noun asymmetry, which was more pronounced in embedded than in coordinated constructions. We suggest that both native and second language learners prioritize linguistic structure over linear distance in their agreement computations.

Preverbal Double Negation in Basque Spanish? Acceptability Judgment Task and Semi-structured Interview

The preverbal double negation construction (i.e., yo tampoco no voy a la fiesta hoy) is ofen cited as a characteristic of Basque Spanish, although its use is undocumented in linguistic studies. The present research aims to fill this void in the literature by analyzing and contrasting the results of two studies on preverbal double negation constructions by Basque Spanish-Basque bilinguals (n 5 20) and Basque Spanish monolinguals (n 5 20). The first study consisted of an acceptability judgment task, in which the participants rated the acceptability of sentences with a preverbal double negation construction using a 5-point Likert scale. The results revealed that neither Basque Spanish-Basque bilinguals nor Basque Spanish monolinguals from this experiment judged the sentences as acceptable. The results of the second study, which was a semi- structured interview, showed that the monolinguals did not produce constructions containing preverbal double negation. The results also showed that six bilingual participants with a higher dominance in Basque than the group average did produce them. It is proposed that the preverbal double negation construction in their Basque Spanish variety is due to the structural influence of Basque.

Research on the Transformation of Service Capability of University Libraries in the Background of "Double First-Class" Construction

Double First-Class construction is the long-term guiding construction program proposed by the education department of China after the deployment of the Project 985 and Project 211 strategic plans to guide the development of China's higher education. As one of the functional departments of colleges and universities, university libraries need to comprehensively examine the challenges faced by the transformation of their own service capabilities in the context of “Double First-Class” construction. Based on this, we will clarify the main direction of transformation and development in serving college personnel training, discipline construction, and document resource supply, in order to better serve our school's Double First-Class construction.

The Current Situation, Problems and Future Paths of Energy Law Education in China

This article focus on the current situation, problems and suggestions of energy law education in china. We can summarizes some main problems in China's energy law education by comparing the development of energy law education between China and foreign countries in terms of student cultivation, curriculum schedule, university teaching staff, academic research, and public participation. In order to overcome the difficulties in China's energy law education and comply with China's double construction and higher education's connotative development requirements, China's energy law education measures include four aspects. First, China must create a first-class teaching staff team. Second, China should cultivate innovative, applied, and integrated development energy law students. Third, China should use journals, research centers, and seminars to enhance academic research. Fourth, the Chinese government at all levels, universities, energy industry, energy practitioners, industry associations, and the public should play important roles in achieving co-governance of energy law education.

Gauge groups and matter spectra in $F$-theory compactifications on genus-one fibered Calabi–Yau $4$-folds without section: Hypersurface and double cover constructions

We investigate gauge theories and matter contents in F-theory compactifications on families of genus-one fibered Calabi-Yau 4-folds lacking a global section. To construct families of genus-one fibered Calabi-Yau 4-folds that lack a global section, we consider two constructions: hypersurfaces in a product of projective spaces, and double covers of a product of projective spaces. We consider specific forms of defining equations for these genus-one fibrations, so that genus-one fibers possess complex multiplications of specific orders. These symmetries enable a detailed analysis of gauge theories. $E_6$, $E_7$, and $SU(5)$ gauge groups arise in some models. Discriminant components intersect with one another in the constructed models, and therefore, discriminant components contain matter curves. We deduce potential matter spectra and Yukawa couplings.

Solutions of associative Yang–Baxter equation and D−equation in low dimensions and associated Frobenius algebras and Connes cocycles

In this work, we compute solutions of the Yang–Baxter associative equation in dimensions one and two. For these solutions, we describe the double constructions of the associated Frobenius algebras, following Bai’s definitions. Besides, we determine related compatible dendriform algebras and solutions of their [Formula: see text]equations. Finally, using symmetric solutions of these equations, we build the double constructions of related Connes cocycles.

Beam–column subassemblies with construction joint in columns above and below the beam

Construction joints in columns are unavoidable in multi-storey reinforced-concrete structures. According to ACI 224.3R-95, construction joints in columns are to be provided below the beam for lower storey columns and above the floor slab for upper storey columns. A review of the literature reveals that little attempt has been made so far to study the effect of cyclic loading on beam–column subassemblies with construction joints in the column above and below the beam. In the present paper, one-third scaled beam–column joint specimens were designed as per relevant provisions of the Indian standard code of practice and detailed as per ductile detailing procedures. Flexural strength ratios of the specimens were 1·2, 1·4, 1·7 and 2·0. Specimens were cast in stages, providing construction joints in the column as per ACI 224.3R-95 to simulate in situ construction. It was observed that ductility, initial stiffness and energy dissipation capacity reduced by 30–44%, 16–19% and 53–64%, respectively, in specimens with double construction joints in the column compared to control specimens.

Double Difference Bases and Thinned Arrays With Twofold Redundancy

Double difference bases (DDBs) and construction of thinned linear arrays with twofold redundancy are discussed in this communication. We present an analytical method, based on the combinatorial tools, to generate twofold redundancy arrays by employing regular DDB patterns separately or combining them with cyclic difference sets. Besides, the bound for DDBs is derived that would be useful to research on thinned array geometries.

Double First-class Construction and China's Contribution to Economics Development

As the crown of social sciences, the discipline construction of economics is of great significance to China's double first-class construction, especially the world first-class discipline construction, and also provides important reality guidance for comprehensively deepening the reform in China to achieve the modernization of state governance. This paper firstly analyzes the matching of the world first-class economics discipline construction with the double first-class strategy orientation, then explores the difficulties and breakthroughs China's world first-class economics discipline construction suffers, and elaborates China's contribution to economics development and innovation. It argues that China's world first-class economics discipline construction needs to conduct the evaluation in accordance with academic standards of international counterparts, and research issues including China should be the concern of international counterparts, so it needs to improve the evaluation system of the discipline classification, strengthen the original research and gather high-level talents to make a breakthrough. Meanwhile, aiming at the development and innovation of economics in China, it points out that there are three directions in which China's economics academia can and should make great contributions, namely the exploration of historical endowments and modern value of China's traditional economic thought, the innovation of original theoretical and methodology research and theoretical abstraction & sublimation based on the practice of China's economic reform development.

Renovation and design of double casement windows with regard to the occurrence of water vapour condensation or mould on the interior surface of the window jamb

The condensation of water vapour on the interior surface is an indicator of construction dysfunction or ignoring of the surroundings temperature and relative humidity. This paper deals with analysis of the occurrence of condensation on the jamb of double casement windows (windows with two window casements). More precisely, this is a surface in the interior where water vapour condensation or mould occur. For the renovation of existing double casement windows, there are different solutions based on window design: application of double insulating glazing on the interior window casement, application of double insulating glazing on the exterior casement, or installation of a simple window. We first describe measurement of an existing double casement window located in a mountain cottage. Second, the results and comparison of 2D thermal model of different types of double casement window construction. Also, the external insulation of the peripheral wall was included in the model.

Study on the Cultivation of the “Double Ability” Talents of Financial Management Specialty Based on “Dual System”

Personnel training program is the guarantee of teaching quality of higher education, and it is also an important basis for achieving the goal of personnel training. The traditional teaching system is usually emphasizing theory, but underestimating practice. With the deepening of teaching reform in higher education, the universities have reached a “theory and practice” combination of training objectives for consensus talents and the construction of modern university teaching system is relatively perfect, but it is still in the exploratory stage in the construction of practical teaching system. In this paper, the author takes application of financial management specialty construction as an example, starting from the theoretical teaching and practical teaching to analyze the main problems existing in the financial management system in theory and practice. She also starts from the development theory and strengthens the practice platform for the construction of a simulation point of view. Then she puts forward to optimize the “dual system” and the structure of “double ability construction”, which can strengthen the integration of financial management theory and practice. So that more suitable applied talents for market demand can be trained.

3-Lie bialgebras and 3-Lie classical Yang–Baxter equations in low dimensions

In this paper, we give low-dimensional examples of local cocycle 3-Lie bialgebras and double construction 3-Lie bialgebras which were introduced in the study of the classical Yang–Baxter equation and Manin triples for 3-Lie algebras. We give an explicit and practical formula to compute the skew-symmetric solutions of the 3-Lie classical Yang–Baxter equation (CYBE). As an illustration, we obtain all skew-symmetric solutions of the 3-Lie CYBE in complex 3-Lie algebras of dimensions 3 and 4 and then the induced local cocycle 3-Lie bialgebras. On the other hand, we classify the double construction 3-Lie bialgebras for complex 3-Lie algebras in dimensions 3 and 4 and then give the corresponding eight-dimensional pseudo-metric 3-Lie algebras.

A Generalization of the Doubling Construction for Sums of Squares Identities

The doubling construction is a fast and important way to generate new solutions to the Hurwitz problem on sums of squares identities from any known ones. In this short note, we generalize the doubling construction and obtain from any given admissible triple $[r,s,n]$ a series of new ones $[r+\rho(2^{m-1}),2^ms,2^mn]$ for all positive integer $m$, where $\rho$ is the Hurwitz-Radon function.

PERANCANGAN PERAHU BERBAHAN FIBER GLASS BERLAPIS KARET UNTUK EVAKUASI BENCANA BANJIR

Most of territory in DKI Jakarta that affected by floods. The floods subscription areas are flooded with varying depths, range from 0.5 meters to 3 meters. The habits of the people affected by the flood are reluctant to evacuate if the flood height is still below 0.5 meters, The flood victims want to evacuate after the flood has reached depth above 1 m. At the height of the flood above 1 m it will be difficult to evacuate to a safer place, because the water level is high and can dangerous for their lives Thus the required means of transportation that can evacuate the flood victims quickly and safely. The design of the boat using rubber-coated Fiber Glass material for the evacuation of flood disaster, its size determination can be adjusted into the Narrow alley that are at least 2 meters wide. Boats are designed with speed 6 knots, hull construction with double hull construction. In the design calculate the strength, load, resistance, main engine and also the stability for passenger safety can be guaranteed. To ensure the safety of passengers in case of unwanted things, then the boat is equipped with life jackets.

Acceptability Judgments of Double Case-Marking Constructions in Korean

With formal experimentation receiving more attention as a means of enhancing reliability of syntactic argumentation within the field of experimental syntax, a few studies have begun to employ such a formal method in order to rigorously test the acceptability of double (or multiple) case-marking constructions. The present study shares this similarity with those previous studies; it also probes into double case-marking constructions in Korean via a formal experimentation (i.e., an acceptability judgment testing). Yet, this study is distinct from such studies to the extent that it substantially increases the empirical basis of the research on this topic on the following grounds. First, it used a sufficiently large sample size (193 participants). Second, it utilized a simple but efficient experimental task, viz. the binary Yes/No task. This task is ideal in that it best fits the assumption that human language works in a dichotomous way. Third, assuming that the double case-marking constructions are heterogeneous in nature, consisting of different sub-constructions whose syntactic operations are different, the present study investigated how different such sub-constructions are in acceptability judgments. Fourth, it compared acceptability judgments of the double case-marking constructions with those of the alternative forms with different markers or constructions being used. Such a comparison was made in a two-pronged direction, viz. within-type and between-type comparisons. More specifically, it was made in terms of the response time for each stimulus sentence as well as the proportion of the response (either `0` representing `unacceptable` or `1` representing `acceptable`).

Micro-syntactic variation in American English Negative Concord

This paper presents a series of quantitative gradient acceptability judgment studies of English negative sentences. Adult native speakers of American English recruited via Amazon’s Mechanical Turk were asked to rate sentences on a scale of 1 to 7 on the basis of their naturalness. The main study compares sentences with the marker n’t and either a negative object (e.g. ‘John didn’t eat nothing’) or a negative subject in canonical position (‘nobody didn’t eat’). Each sentence type has two possible interpretations, one in which the two negatives contribute a single semantic negation, the so-called Negative Concord reading, and another in which the two negations yield a semantic Double Negation logically equivalent to an affirmative. While mean acceptability ratings were below the median for all items, statistical analyses of the gradient data revealed that speakers prefer Negative Concord over Double Negation readings for sentences with negative objects. To rule out a processing explanation for the preference for negative objects over sentence initial negatives, a follow-up study tested the acceptability of sentences with a single negative subject or object and no negative marker. This revealed a preference for subjects, suggesting that the object preference in the two negatives study is a true grammatical effect. A third study revealed that Double Negation constructions are unacceptable overall even in explicit denial contexts, and a fourth study added Negative Auxiliary Inversion constructions (e.g. ‘Didn’t nobody eat’), to compare three types of Negative Concord. The results of all four studies are argued to reveal an English grammar that generates both Negative Concord and Double Negation, and in which Negative Concord is generated despite its unacceptability and reported absence in usage.

SHRINKAGE AND CREEP EFFECT ANALYSES OF DOUBLE COMPOSITE CONTINUOUS BOX-GIRDER BRIDGE CONSTRUCTED BY PRE-JACKING METHOD

Continuous double steel and concrete composite beam is a new structural system developed on the basis of common steel and concrete composite beam. Controlling concrete slab crack width in a continuous double composite beam is a significant content in the bridge construction process. Jacking-up and landing bearing supports method is applied to a double composite girder bridge construction and its structural mechanical behaviors in the whole process will be simulated. By using of User Programmable Features and ANSYS Parametric Design Language, the commercial FEM software ANSYS was further developed. The exponential model of concrete creep and the implicit solution of concrete creep equation under the action of variable stress were introduced into ANSYS, to realize the concrete shrinkage and creep effect analysis of double composite continuous box-girder bridges constructed by pre-jacking method. The results show that it is improved that the stress state of the top concrete slab in the negative moment regions by pre-jacking method. Due to the effect of concrete creep, the concrete creep will cause tensile stress in the negative moment regions of the composite beam, which will reduce the compressive stress in the top concrete slab. The effect of prestressing is greatly affected by pre-jacking value, and the creep of the concrete also causes the stress redistribution of the concrete and the steel beam.
