Abstract:

Hydrogen sulfide (H2S) has been proven to be a multifunctional signaling molecule in plants. In this study, we attempted to explore the effects of H2S on the climacteric fruit tomato during postharvest storage. H2S fumigation for 1 d was found to delay the peel color transition from green to red and decreased fruit firmness induced by ethylene. Further investigation showed that H2S fumigation downregulated the activities and gene expressions of cell wall–degrading enzymes pectin lyase (PL), polygalacturonase (PG), and cellulase. Furthermore, H2S fumigation downregulated the expression of ethylene biosynthesis genes SlACS2 and SlACS3. Ethylene treatment for 1 d was found to induce the expression of SlACO1, SlACO3, and SlACO4 genes, whereas the increase was significantly inhibited by H2S combined with ethylene. Furthermore, H2S decreased the transcript accumulation of ethylene receptor genes SlETR5 and SlETR6 and ethylene transcription factors SlCRF2 and SlERF2. The correlation analysis suggested that the fruit firmness was negatively correlated with ethylene biosynthesis and signaling pathway. The current study showed that exogenous H2S could inhibit the synthesis of endogenous ethylene and regulate ethylene signal transduction, thereby delaying fruit softening and the ripening process of tomato fruit during postharvest storage.

Abstract:

During trial-to-trial movement adaptation, the motor system systematically reduces extraneous muscle forces when kinematic errors experienced on previous movements are small, a phenomenon termed “slacking.” There is also growing evidence that the motor system slacks continuously (i.e., in real-time) during arm movement or grip force control, but the initiation of this slacking is not well-characterized, obfuscating its physiological cause. Here, we addressed this issue by asking participants ( n = 32) to track discrete force targets presented visually using isometric grip force, then applying a brief, subtle error-clamp to that visual feedback on random trials. Participants reduced their force in an exponential fashion, on these error-clamp trials, except when the target force was <10% maximum voluntary contraction (MVC). This force drift began <250 ms after the onset of the error-clamp, consistent with slacking being an ongoing process unmasked immediately after the motor system finished reacting to the last veridical feedback. Above 10% MVC, the slacking rate increased linearly with grip force magnitude. Grip force variation was approximately 50–100% higher with veridical feedback, largely due to heightened signal power at ~1 Hz, the band of visuomotor feedback control. Finally, the slacking rate measured for each participant during error-clamp trials correlated with their force variation during control trials. That is, participants who slacked more had greater force variation. These results suggest that real-time slacking continuously reduces grip force until visual error prompts correction. Whereas such slacking is suited for force minimization, it may also account for ~30% of the variability in personal grip force variation.NEW & NOTEWORTHY We provide evidence that a form of slacking continuously conditions real-time grip force production. This slacking is well-suited to promote efficiency but is expected to increase force variation by triggering additional feedback corrections. Moreover, we show that the rate at which a person slacks is substantially correlated with the variation of their grip force. In combination, at the neurophysiological level, our results suggest slacking is caused by one or more relatively smooth neural adaptations.

Abstract:

In this study, we present a low-cost and simple method to treat spent lead–acid battery wastewater using quicklime and slaked lime. The sulfate and lead were successfully removed using the precipitation method. The structure of quicklime, slaked lime, and resultant residues were measured by X-ray diffraction. The obtained results show that the sulfate removal efficiencies were more than 97% for both quicklime and slaked lime and the lead removal efficiencies were 49% for quicklime and 53% for slaked lime in a non-carbonation process. After the carbonation step, the sulfate removal efficiencies were slightly decreased but the lead removal efficiencies were 68.4% for quicklime and 69.3% for slaked lime which were significantly increased compared with the non-carbonation process. This result suggested that quicklime, slaked lime, and carbon dioxide can be a potential candidate for the removal of sulfate and lead from industrial wastewater treatment.

Abstract:

Humid coastal dune slacks are an endangered habitat in Northwestern Europe. In the UK, dune slacks are currently classified as being in ‘unfavourable’ condition, with projected decrease in England of up to 30% by 2036. Studies in mainland Europe suggest that regional factors (e.g. slack area, age, and isolation) are more important than local factors (e.g. soil, pH, soil nutrient and water status) in driving successional vegetation processes in coastal slacks. However, this has never been tested for the UK, where approximately 14% of European slacks occur. We used previously established survey protocols to test whether regional factors are more important than local factors in UK coastal slacks, along the Sefton Coast in NW England. We found that slack area and slack age were more important than local factors in driving plant community composition and species richness. We also showed that higher levels of management, such as active grazing and invasive shrub and tree removal, are effective in increasing soil moisture levels in slacks. Our results suggest that similar successional processes are likely to be important in slacks in the NW of England, compared to mainland Europe.

Abstract:

Rab27a is a GTPase associated with insulin-containing secretory granules of pancreatic β-cells. Selective reduction of Rab27a expression by RNA interference did not alter granule distribution and basal secretion but impaired exocytosis triggered by insulin secretagogues. Screening for potential effectors of the GTPase revealed that the Rab27a-binding protein Slac2c/MyRIP is associated with secretory granules of β-cells. Attenuation of Slac2c/MyRIP expression by RNA interference did not modify basal secretion but severely impaired hormone release in response to secretagogues. Although β-cells express Myosin-Va, a potential partner of Slac2c/MyRIP, no functional link between the two proteins could be demonstrated. In fact, overexpression of the Myosin-Va binding domain of Slac2c/MyRIP did not affect granule localization and hormone exocytosis. In contrast, overexpression of the actin-binding domain of Slac2c/MyRIP led to a potent inhibition of exocytosis without detectable alteration in granule distribution. This effect was prevented by point mutations that abolish actin binding. Taken together our data suggest that Rab27a and Slac2c/MyRIP are part of a complex mediating the interaction of secretory granules with cortical actin cytoskeleton and participate to the regulation of the final steps of insulin exocytosis.

Abstract:

Slaked lime is a suspension of hydrated lime in water that can contain up to 40% of solids in suspension. The quality of the suspensions of slaked lime depends on the quality of lime used and on a careful choice of the conditions during the hydration process. A high quality slaked lime is a product with a small quantity of insoluble residues, high specific surface area, high alkaline content and small particle size. Therefore, the objective of this work was to study the best conditions of temperature and concentration to produce a superior slaked lime. A statistic analysis was performed using the experimental results in order to optimize the operational conditions of the hydration process. The use of hydration water around 74 °C, of small particles of CaO (0.144 mm) and of a CaO/H2O ratio around 220 g/L contributed to the production a slaked lime suspension of fine quality.

Abstract:

Fluxed iron ore pellets, obtained by application of raw limestone are widely used in the iron ore share of blast furnace charge. Decomposition of the raw limestone in the process of the pellets burning requires considerable energy. The purpose of the work was to study quality variation of raw and burned pellets, as well as metallurgical properties variation, caused by substitution of limestone by burned and slaked lime. Physical simulation of the pelletizing process and pellets burning process was done. In the process of the experiment simulation of total and partial substitution of limestone by lime as well as with partial substitution of limestone by slaked lime was accomplished. Diagrams of plasticity and strength of raw and burned pellets at various shares of limestone, burned and slaked lime presented. It was shown that the strength during reducing RDI-1 (ISO 4696-1) has a tendency to increase when application of lime. Increase of Index RDI+6,3 value accounted for 3.6% (abs.) at application of quicklime and slaked lime correspondently. Index RDI−3,15 value decreased by 1.06% (abs.) and 0.88% (abs.) and that of index RDI−0,5 – by 0.75% (abs.) and 0.8% (abs.) at application of quicklime and slaked lime correspondently. It was assumed that application of slaked lime can contribute to bentonite share decrease and thus to total iron content increase. It was established that application of lime enables to decrease heat consumption for pellets burning. Application of slaked lime instead of limestone in the process of pellets production results in an increase of their strength during reducing and compression strength. This effect enables to reach a higher efficiency in the process of such pellets usage in blast furnace charge or in the process of their metallization, comparing with the usage of pellets fluxed by limestone.

Abstract:

In the literature there is no complete data on the use of slaked lime as a disinfectant disinfectant. All veterinary publications indicate that a 10 - 20% solution of slaked lime has a disinfecting effect. However, the technology of carrying out, as well as modes of disinfection, are not specifically indicated in any literature. There is no data on which infectious diseases they affect, at what concentration, exposure and consumption of the disinfectant it can be applied, on smooth or rough surfaces, the frequency of whitewashing or wet disinfection, etc. Until now, the issue of the solubility of slaked lime in water and other chemical compounds has not been completely resolved. In addition, the lack of a disinfectant - 10 - 20% slaked lime, is a low disinfection efficiency, high corrosion activity in relation to metal products, a large flow rate of a solution of 1 -1.5 l / m2, which is carried out 2 - 3 times by whitewash.

Abstract:

The System Level Applications of Adaptive Computing (SLAAC) project is defining an open, distributed, scalable, adaptive computing systems architecture based on a highspeed network cluster of heterogeneous, FPGA-accelerated nodes. Two reference implementations of this architecture are being created. The Research Reference Platform (RRP) is a MyrinetTM cluster of PCs with PCI-based FPGA accelerators (SLAAC-1). The Deployable Reference Platform (DRP) is a Myrinet cluster of PowerPCTM nodes with VME-based FPGA accelerators (SLAAC-2) and a commercial 6U-VME quad- PowerPC board (CSPI M2641S) serving as the carrier. A key strategy proposed for successful ACS technology insertions is source-code compatibility between the RRP and DRP platforms. This paper focuses on the development of the SLAAC-1 and SLAAC-2 accelerators and how the network-centric SLAAC system-level architecture has shaped their designs. A preliminary mapping of a Synthetic Aperture Radar/Automatic Target Recognition (SAR/ATR) algorithm to SLAAC-2 is also discussed.

Abstract:

Sentence compression is the task of compressing a long sentence into a short one by deleting redundant words. In sequence-to-sequence (Seq2Seq) based models, the decoder unidirectionally decides to retain or delete words. Thus, it cannot usually explicitly capture the relationships between decoded words and unseen words that will be decoded in the future time steps. Therefore, to avoid generating ungrammatical sentences, the decoder sometimes drops important words in compressing sentences. To solve this problem, we propose a novel Seq2Seq model, syntactically look-ahead attention network (SLAHAN), that can generate informative summaries by explicitly tracking both dependency parent and child words during decoding and capturing important words that will be decoded in the future. The results of the automatic evaluation on the Google sentence compression dataset showed that SLAHAN achieved the best kept-token-based-F1, ROUGE-1, ROUGE-2 and ROUGE-L scores of 85.5, 79.3, 71.3 and 79.1, respectively. SLAHAN also improved the summarization performance on longer sentences. Furthermore, in the human evaluation, SLAHAN improved informativeness without losing readability.

Full text

Abstract:

In recent years, there has been an increasing interest in applying inverse data envelopment analysis (DEA) to a wide range of disciplines, and most applications have adopted radial-based inverse DEA models. However, results given by existing radial based inverse DEA models can be unreliable as they neglect slacks while evaluating decision-making units’ (DMUs) overall efficiency level, whereas classic radial DEA models measure the efficiency level through not only radial efficiency index but also slacks. This paper points out these disadvantages with a counterexample, where current inverse DEA models give results that outputs shall increase when inputs decrease. We show that these unreasonable results are the consequence of existing inverse DEA models’ failure in preserving DMU’s efficiency level. To rectify this problem, we propose a revised model for the situation where the investigated DMU has no slacks. Compared to existing radial inverse DEA models, our revised model can preserve radial efficiency index as well as eliminating all slacks, thus fulfilling the requirement of efficiency level invariant. Numerical examples are provided to illustrate the validity and limitations of the revised model.

Abstract:

The type of navigation interface in a virtual environment (VE)---head slaved or indirect---determines whether or not proprioceptive feedback stimuli are present during movement. In addition, teleports can be used, which do not provide continuous movement but, rather, discontinuously displace the viewpoint over large distances. A two-part experiment was performed. The first part investigated whether head-slaved navigation provides an advantage for spatial learning in a VE. The second part investigated the role of anticipation when using teleports. The results showed that head-slaved navigation has an advantage over indirect navigation for the acquisition of spatial knowledge in a VE. Anticipating the destination of the teleport prevented disorientation after the displacement to a great extent but not completely. The time that was needed for anticipation increased if the teleport involved a rotation of the viewing direction. This research shows the potential added value of using a head-slaved navigation interface---for example, when using VE for training purposes---and provides practical guidelines for the use of teleports in VE applications.

Abstract:

In performance measurement of the firms using tools such as data envelopment analysis (DEA) models, weak efficient units are almost appeared as reference points in the models. To avoid zero weights or equivalently non-zero slacks in DEA assessment, weights restrictions are used frequently. In DEA literature, two-stage procedures are developed to deal with non-zero slacks based on restricting input/output weights in multiplier formulating the CCR DEA model. In this paper, a single-stage approach for efficiency evaluation is developed to ensure zero slacks in target setting and avoid weights dissimilarity. A real case on electricity distribution companies in Iran has been given to demonstrate the applicability of the proposed approach.

Abstract:

To improve high temperature stability performance, some additive materials, such as cement, slaked lime and lignin were mixed into open graded asphalt friction course (OGFC). With different dosage and various admixtures, samples of different dimension were made. Then, rutting tests were put forward for dynamic stability calculation. High temperature stability of OGFC mixture can be obviously improved, whatever adding cement or slaked lime, even lignin fibre instead of mineral powder. As for substitute cement for mineral powder, when replacement volume is 66.6%, high temperature stability of OGFC-13 is highly improved with dynamic stability 1308 times / mm. When substitute slaked lime for mineral powder is 100%, dynamic stability of OGFC-13 mixture is 1910 times / mm. High temperature stability of OGFC-13 mixture can be greatly improved by 0.2% lignin fibre, with dynamic stability 1424 times / mm.

Abstract:

The search of new disinfectants with a wide spectrum of antimicrobial activity of low toxicity and not hazardous in use, not requiring of creation of special storage conditions, convenient in use and not adversely affecting on processed items, affordable, is an urgent task of veterinary science. The article presents the results of laboratory tests of new bactericidal compositions, which include: 20% hydrated lime, 1.3 and 5% sodium chloride, as well as foaming agent PO-6K on test surfaces made of stainless steel, galvanized gland, tile, wood and concrete. As a test of microorganisms, museum cultures of E. coli (strain 1257) and Staphylococcus aureus (strain 209-P) were used. During the experiments, disinfection regimes were established (concentration, exposure, consumption of disinfectant) for disinfecting of smooth and rough test surfaces. At the same time, it was found that slaked lime solutions of 10 and 15% concentration did not have disinfecting activity even after triple whitening or irrigation of test surfaces contaminated with E. ooli (strain 1257), St. aureus (strain 209-P) at a rate of 0,5 l/m2 for smooth and 1 l/m2 - for rough surfaces. 20% solution of slaked lime, which destroys only Escherichia coli on smooth surfaces in 3 hours of exposure at the rate of 0,5 l/m2, and rough surfaces in 24 hours of exposure at the rate of 1,0 l/m2, has a disinfecting effect. At the same time, adding 1,3 and 5% sodium chloride to the slaked lime solution, the disinfecting activity of slaked lime also increases sharply; adding to 20% slaked lime 3 and 5% sodium chloride disinfects Escherichia coli and staphylococcus in 3 hours, based on smooth 0,5 l/m2, and for rough surfaces - 1 l/m2. Studies have also found that the addition of 3-5% sodium chloride, 5% foaming agent to 20% slaked lime solution reduces the consumption of the disinfectant in 2 times without reflecting the indicators of disinfection efficiency. When a foaming agent is added to the solution, the resistance (adhesion) of the foam on the vertical and ceiling surfaces increases on 14-18 minutes, and on the floor the foam is held in 1-1,5 hours, which helps to reduce the runoff of the solution.

Abstract:

Komunitas plankton memiliki peran penting pada proses rantai makanan, siklus nutrien dan proses suksesi awal wet dune slacks. Kawasan wet dune slacks merupakan cekungan yang berada di antara punggung gumuk dan kondisi permukaan air tanah sangat bervariasi tergantung musim. Habitat unik yang telah dilindungi di benua Eropa ini justru belum banyak dipelajari di Indonesia. Tujuan penelitian ini adalah untuk mempelajari distribusi dan kemelimpahan plankton di wet dune slacks serta faktor fisiko-kimia yang paling mempengaruhi distribusi dan kemelimpahannya. Pencuplikan sampel dilakukan pada bulan Februari 2018 di Gumuk Pasir Parangtritis, Bantul, Daerah Istimewa Yogyakarta. Sampel air dicuplik menggunakan ember sebanyak 10 liter dengan 3 ulangan pada 5 wet dune slacks yang berbeda. Sampel air kemudian disaring menggunakan plankton-net ukuran 120 mesh serta diukur parameter fisiko-kimianya. Hasil dari pengamatan sampel plankton menunjukkan terdapat 37 spesies diatom pennate, 1 spesies diatom sentrik, 23 spesies alga unisel, 28 spesies alga koloni, 18 spesies alga filamen, 3 spesies dinoflagellata, 6 spesies protozoa berklorofil, 22 spesies rotifera, 6 spesies cladocera, 11 spesies ostracoda, 5 spesies copepoda, dan 5 spesies protozoa. Spesies plankton yang berhasil mengsuksesi kawasan wet dune slacks merupakan spesies yang memiliki strategi bertahan di habitat kekeringan dengan berubah ke fase istirahat, cyst, spora, dan resting eggs.

Abstract:

Immunocastraten worden minstens vier weken vóór de slacht gevaccineerd om berengeur effectief te reduceren en de vleeskwaliteit te verbeteren ten opzichte van intacte beren. Uit een onderzoek van ILVO en UGent (LANUPRO) blijkt dat het toepassen van de tweede injectie (op acht of zes weken vóór de slacht) echter niet helpt om de vleeskwaliteit verder te verbeteren. Het blijkt zelfs economisch minder voordelig te zijn voor de varkenshouder aangezien de vroeg-gevaccineerde immunocastraten een hogere voederconversie en lagere slachtkwaliteit hebben.

Abstract:

The magnesium slag is discarded from production of magnesium metal from dolomite. However the magnesium slag is slaked in some factories by means of sprinkling water to prevent from dust pollution. The possibility of slaked magnesium slag (SMS) to play a role of mineral admixture for concrete was investigated by experiments of mortars and concretes prepared with SMS. The results revealed that SMS was still reactive. When SMS is substituted for 30% of cement, its reactivity index is equivalent to that of grade I fly ash (FA). And when SMS is used as mineral admixture to prepare concrete, it contributes to strength of concrete no less than S95 ground granulated blast-furnace slag (GGBS). Better effect of binary or ternary blend can be obtained by combining SMS with GGBS and/or FA. Because the magnesium slag is slaked, SMS has no problem on soundness, so it can be applied in concrete as mineral admixture.

Abstract:

This paper aims to investigate the three-stage theory of international expansion in the long run from the perspective of firm behavior. Although this topic has been mostly explored using data from developed countries, this paper aims to fill the research gap in an emerging market by using an extensive unbalanced panel data of 12,704 unlisted Vietnam manufacturing enterprises from the General Statistics Office during 2007 to 2012. The findings illustrated a significant S-shaped relationship between internationalization and performance. Notably, the results depict significantly moderating effects of both high-discretion slacks and low-discretion slacks on the internationalization–performance relationship across three stages of global expansion as an enterprise enhances this relationship in the first and third stage although this worsens it in the middle stage. The empirical results suggest that firms should determine the optimum level of internationalization and slacks in addition to balancing their costs with their real gains.

Abstract:

The magnesium slag is discarded from production of magnesium metal from dolomite. However the magnesium slag is slaked in some factories by means of sprinkling water to prevent from dust pollution. The possibility of slaked magnesium slag (SMS) to play a role of raw material and blend for portland cement was investigated by experiments of raw mix preparation, clinker calcining and property determination of cement pastes and mortars. The results revealed that SMS was still reactive. The raw mix with SMS was of excellent burnability that would contribute to energy saving. As a raw material, SMS can be used for calcining clinker of good quality; and as a blend it is suitable for production of ordinary portland cements. Because the magnesium slag is slaked, SMS has no problem on soundness. Higher strength of cement can be obtained in form of binary blends consisting of SMS and ground granulated blast-furnace slag or fly ash.

Abstract:

This work is inspired by the recent paper of Mytilinaios and Slaman [9] on the infinite injury priority method. It may be considered to fall within the general program of the study of reverse recursion theory: What axioms of Peano arithmetic are required or sufficient to prove theorems in recursion theory? Previous contributions to this program, especially with respect to the finite and infinite injury priority methods, can be found in the works of Groszek and Mytilinaios [4], Groszek and Slaman [5], Mytilinaios [8], Slaman and Woodin [10]. Results of [4] and [9], for example, together pinpoint the existence of an incomplete, nonlow r.e. degree to be provable only within some fragment of Peano arithmetic at least as strong as P- + IΣ2. Indeed an abstract principle on infinite strategies, such as that on the construction of an incomplete high r.e. degree, was introduced in [4] and shown to be equivalent to Σ2 induction over the base theory P- + IΣ0 of Peano arithmetic.

Abstract:

Concern about over-harvesting wild populations of ramps (Allium tricoccum Ait.) has led to interest in planting ramps as an under-story agroforestry crop. To see if ramps would respond to Ca amendments in an acidic site, we planted three types of ramps bulbs and broadcast slaked lime (3316 kg·ha–1) or gypsum (7704 kg·ha–1) on a Rayne silt loam (fine-loamy, mixed, mesic Typic Hapludults). After 3 years, surface-applied slaked lime raised Ca levels as deep as the 22.5 to 30 cm layer, which showed an increase of 0.34 cmolc·kg–1, and increased pH in the 2.5 to 5.0 cm layer from 3.96 to 4.67. Gypsum application raised Ca concentration in the 22.5 to 30 cm layer from 0.2 in the control to 0.7 cmolc·kg–1, but had little effect on pH anywhere in the profile. In plots harvested after 2 years, both amendments increased plant survival and per-plant weight, compared to controls. In plots harvested after 3 years, ramps grown in the slaked lime treatment were heavier than in the gypsum treatment indicating that slaked lime, which raised pH as well as supplied Ca, was probably the better amendment. Single or joined bulbs survived better than bulbs obtained by breaking joined bulbs in two. While more research is needed to overcome limitations to commercial planting of ramps in acidic sites, our data show that Ca application is beneficial to growth and survival of ramps.

Abstract:

The study results of the calcareous composites made with the use of activated mixing water are presented. Quicklime and slaked lime are used as lime binders. The mixing water was activated by the electric current and magnetic field in various modes. The effect of water activation on the physical and mechanical properties of slaked and quicklime composites and the resistance to the effects of the biological environment are studied. The water for mixing electromagnetic treatment effectiveness analysis is presented. The increase in the density of materials based on lime, trapped in activated water using ultrasound tests is proven. It was found that the mixing water activation affects the structure formation of composites and, under certain activation conditions, leads to an increase in such physical and mechanical parameters as strength and hardness. The positive effect of the mixing water activation on the lime-based materials’ resistance to microbial growth has been established, and the decrease in the growth of composites based on quicklime and slaked lime has been proved.

Full text

Abstract:

In this letter, we explore the idea of modeling slack variables in support vector machine (SVM) approaches. The study is motivated by SVM+, which models the slacks through a smooth correcting function that is determined by additional (privileged) information about the training examples not available in the test phase. We take a closer look at the meaning and consequences of smooth modeling of slacks, as opposed to determining them in an unconstrained manner through the SVM optimization program. To better understand this difference we only allow the determination and modeling of slack values on the same information—that is, using the same training input in the original input space. We also explore whether it is possible to improve classification performance by combining (in a convex combination) the original SVM slacks with the modeled ones. We show experimentally that this approach not only leads to improved generalization performance but also yields more compact, lower-complexity models. Finally, we extend this idea to the context of ordinal regression, where a natural order among the classes exists. The experimental results confirm principal findings from the binary case.

One of the perspective directions is the use the composite binder, containing nanostructuring additives, in the formulation of dry construction blends. The consolidation about the composition and properties of additives based on the synthesized aluminosilicates, intended for finishing limy dry construction blends are provided in work. It is established that the synthesized aluminosilicates are characterized by high activity of interaction of the additive with a lime. The influence of the additive on durability of a limy composite is shown. It is revealed that composition binder, consisting of a slaked lime and a synthesized zeolites possesses the larger water resistance in comparison with a slaked lime.

Abstract:

Recently, potholes have drawn attention as a major pavement distress. In Korea and other countries, slaked lime is used to improve the moisture resistance of asphalt mixtures in order to prevent road damages by moisture. The present study was conducted to evaluate the moisture resistance of asphalt mixtures containing air-cooled slag having a chemical composition similar to that of slaked lime. To evaluate the moisture resistance of asphalt mixtures containing air-cooled slag, a moisture resistance test that is applied in Korea and other countries was performed. The evaluation of the moisture resistance of asphalt mixtures containing air-cooled slag showed that the coverage ratio measured by the dynamic immersion test was about 80%, which was similar to that of the asphalt mixtures containing slaked lime. In the case of the indirect tensile strength test, the TSR value tends to increase with increasing the air-cooled slag content of the specimens. But the indirect tensile strength was slightly lower in the specimen containing 3% air-cooled slag. The Hamburg wheel tracking test showed that the moisture resistance of the specimens produced in a laboratory and in a plant was good but that of the specimen containing 3% air-cooled slag was slightly lower. The laboratory experiment performed in the present study showed that the moisture resistance was improved by the addition of air-cooled slag, which has a similar composition with slaked lime, to asphalt mixtures. However, when the entire filler of the asphalt mixture was replaced by air-cooled slag, the strength was slightly decreased, indicating that an appropriate amount of air-cooled slag should be added. The applicability of air-cooled slag to asphalt pavement material may need to be studied through a microstructure analysis and a long-term pavement performance test to investigate the mechanism more accurately.

Full text

Abstract:

Data Envelopment Analysis (DEA) is a mathematical programming approach to measure the relative efficiency of peer decision making units (DMUs) which use multiple inputs to produce multiple outputs. One of the drawbacks of traditional DEA models is the neglect of internal structures of the DMUs. Network DEA models are able to overcome the shortcoming of the traditional DEA models. In network DEA a DMU is made up of some divisions linked together by intermediate products. An intermediate product has the dual role of output from one division and input to another one. Improving the efficiency of one process may reduce the efficiency of another process. To address the conflict caused by the dual role of intermediate measures, this paper presents a new approach which categorizes the intermediate measures into either input or output type endogenously, while keeping the continuity of link flows between divisions. This categorization allows us to measure the inefficiencies associated with intermediate measures and account their indirect effects on the objective function. In this paper we propose a new Slacks-based measure which includes any nonzero slacks identified by the model and inherits the properties of monotonicity in slacks and units invariance from the conventional SBM approach.

Abstract:

Data envelopment analysis (DEA) as a nonparametric programming approach has been widely extended and applied in many areas. Conventional DEA models can well measure the efficiency of inefficient decision-making units (DMUs) but cannot further discriminate the efficient DMUs. A lot of methods are proposed to address this problem. One of the most important methods is the slacks-based measure of super-efficiency model (S-SBM model) developed by Tone in 2002. However, the projection for a DMU on the efficient frontier identified by S-SBM model may not be strongly Pareto-efficient that makes the super-efficiency score misestimated. This paper revises the usual slacks-based measure of super-efficiency by incorporating input saving and output surplus scaling factors into the objection function for measuring DMUs. We integrate SBM model and S-SBM model effectively and yield input saving and output surplus scaling factors as well as input and output slacks under only one integrated model. According to the study, the projection reference point identified by our method is strongly Pareto-efficient. Meanwhile, how each decision variable influences the efficiency score for a specific DMU is revealed and illustrated through two numerical examples and an empirical study in paper chemical mills.

This paper investigates the effect of both FS and HR slack together on firm performance and how different levels of these slack resources affect performance of private-owned enterprises (POEs) and state-owned enterprises (SOEs). Hypotheses are tested using a longitudinal data set of 11,985 listed Chinese companies from 2000 to 2009. Findings reveal that the unabsorbed-financial slack and HR slack show an inverse U shape relationship on firm performance for both POEs and SOEs. However, a less-negative interaction occurs for unabsorbed-financial and HR slacks for POEs. The absorbedfinancial and HR slacks also shows an inverse U shape relationship on performance and this relationship does not have a significant negative effect on SOE’s performance. The article concludes with theoretical contributions and practical implications of the findings.

Abstract:

This paper is about an experiment which should prove that slaked lime is suitable as an ecological moisture retardant. Therefore, the performance of straw, sheep wool, hemp and directed hemp covered with slaked lime was monitored over a long period. The other half of the probes were uncovered to serve as reference data. The main focus of this experiment is to determine the moment when the probes start to mold as extreme humidity in reality only lasts for a short time. During the experiment the used material is continuously exposed to moisture whereas under non-experimental conditions exposure to moisture would last for a much shorter period of time (cooking, cleaning, etc.) This paper only covers the performance of straw and sheep wool covered with lime. Also the spreading of mold will not take place.

Abstract:

Based on radiocarbon and optically stimulated luminescence (OSL) results obtained in the last 5 yr, this paper discusses the absolute chronology of the formation of one of the largest sand dunes within NW Belgium, the Great Ridge of Maldegem-Stekene. Multiproxy analysis of 6 sedimentary sequences points to a complex formation history covering the entire Late Glacial. Dry phases, characterized by eolian deflation and sedimentation, alternated with wet phases in which numerous mostly shallow dune slacks were filled with freshwater. The latter reached their highest water level during the first half of the Allerød, attracting both animals (e.g. European elk) and humans (Federmesser hunter-gatherers). Near the end of the Allerød, all dune slacks finally disappeared as they were filled in with windblown sand ("coversand"), likely forcing prehistoric hunter-gatherers to leave the area.
