Full textAbstract:
As cultural life becomes rich,people have increasing demands for stage effects on performances.In some top grade cultural sites and entertainment venues,hydraulic lift stages replace traditional stationary stages for the sake of creating lively three-dimensional performance effects.However, stage hydraulic system is relatively huge.It’s not easy to check out the location of the fault quickly, which makes the efficiency of resolving the fault low. Based on the simulation of the circuit of stage hydraulic system,by means of collecting,transforming and analyzing pressure and flow signal of “final mile” of stage hydraulic system under different pressure conditions,we can summarize the relationship between pressure and flow as well as realize remote monitoring. And then we can determine whether there is a fault,and resolve the fault in time. In addition,a solenoid valve is added to the circuit,which makes the two-way circulation loop possible.

Full textAbstract:
Pollen germination is useful for the estimation of pollen viability. For three cultivars from the Explorer™ series, Champlain, Nicolas and Frontenac, a liquid medium with a pH of 5.6 and a saccharose concentration of 15% provides optimal germination conditions. Four flower stages were determined and evaluated according to the following scale: flower bud at stage 0 (closed bud), stage 1 (closed petals but open sepals), stage 2 (bud with petals three-quarters open) and stage 3 (fully open flower). Pollen germination was higher when the pollen was collected at stages 0 and 1 for Champlain, at stages 1 and 2 for Frontenac and at stage 2 for Nicolas. Based on the results of the evaluation of pollen drying techniques, it is recommended that pollen be dried for 24 h in darkness before use in crossing. Key words: Rosa, rose, rose breeding, pollen harvesting, pollen drying, pollen germination test

This grounded theory research paper presents an analysis of the motivation of young men in commencing a three-stage leadership development program and the critical influences impacting their decision to return for subsequent stages of the program. The key findings are that both people and program influences are significant. The key program influences initially are the community and group in Stage 1 along with certain program-specific elements. This creates a momentum towards Stage 2 where a three-day wilderness Solo experience emerges as the core category / central phenomenon – drawing participants from Stage 1 and being motivational towards Stage 3. Specific program elements and “lenses” are identified for future research.

The current project extended over five months, and used SFBT interviews with six identified pupils in years 8 and 9 at a secondary school in Richmond upon Thames, who were presenting with social and behavioural difficulties. These students were receiving no other ‘formal’ educational or clinical interventions at the time, and were considered able to be helped through early intervention. The project aimed to reduce the incidence of inappropriate behaviours and the likelihood of exclusion for these students, to improve their ability to discuss and reflect upon their difficulties and hence enhance their social skills with adults.Twenty-five interviews were carried out: I interviewed the student, a parent and a key teacher individually to identify strategies that could help the pupil. I finalised these strategies at a fourth meeting with all three parties, and distributed the list of suggestions. It remained the responsibility of the key teacher and of the school to follow the suggestions through and liaise with all relevant teachers.The project was evaluated in a range of ways and five of the six students clearly made small but noticeable improvements over two terms. In addition there seemed to be a number of interesting and positive gains for the school, which could be further developed.

In this paper, we identify the key parameters to consider in a decision model on internationalization of operations. In order to propose these parameters, the GLOBOPE framework was adopted as the basis of this work. This framework contemplates the three commonest challenges of global operations configuration for industrial manufacturing companies in an internationalization process, which are: new facility implementation (NFI); global suppliers’ network development (GSND); multisite production network configuration. A set of suitable parameters is herein provided for NFI and GSND in the analysis stage from strategic, tactical and operational decision levels. These parameters could be used in the future as a basis for the development of quantitative tools for decision making on the internationalization of operations.

Full textAbstract:
Purpose A better understanding of the processes that shape households’ adaptation decisions is essential for developing pertinent policies locally, thereby enabling better adaptation across scales and multiple stakeholders. This paper aims to examine the determinants of household decisions to adapt, it is also possible to target factors that facilitate or constrain adaptation. This helps to identify key components of current adaptive capacity, which leads to important insights into households’ competence to adapt in the future. Design/methodology/approach This paper takes a full-pledged approach examining factors and processes that shape households’ climate adaptation decision-making in rural Cambodia at three levels: adaptation status, adaptation intensity and choices of adaptation strategy. The three-stage analyses are materialized by applying the double hurdle model and multivariate probit model, which provides a potential way to systematically assess household adaptation decision-making in rural settings. Findings Results show a high level of involvement in adaptation among local households who are facing multiple stressors including climatic risks. The findings suggest that perceived climate change influence households’ decisions in both adaptation status and intensity. Access to financial credit, farmland size, water availability and physical asset holdings are identified as key factors promoting the adoption of more adaptation measures. To facilitate adaptation, collective effort and support at community level is important in providing knowledge based climate information dissemination and early warning systems. Public sector support and development aid programs should focus on positive triggers for targeted community and household adaptation. Originality/value The study, to the authors’ best knowledge, is one of the first studies to investigate the determinants of local adaptation decision-making systematically in Cambodia. It also provides a comprehensive approach to improve understanding of adaptation decision-making processes by exploring how various capital assets are associated with different stages of adaptation decisions. The findings contribute to policy implications enlightening adaptation planning at multi-scales with knowledge of key factors, which enhance local adaptive capacity to reduce climate change vulnerability.

Full textAbstract:
We have been working in the area of cancer screening modeling for many years. A well-known and frequently used model in cancer screening is the progressive three-state model [1], where all cancer patients are assumed to go through three states: the disease-free state when one is cancer-free or the cancer is in an early stage that no technology can find; the preclinical state when one without symptom but cancer could be detected by screening, and the clinical state when cancer related symptoms show up. There are three key parameters in the model: a) the screening sensitivity, the probability of a positive screening result given that one is in the preclinical state; b) the distribution of sojourn time, which measures the time duration in the preclinical state; and c) the transition density, which measures the time duration in the disease-free state, or the onset age of the preclinical state. These three parameters are called the key parameters since they determines the screening processes and all other terms, for example, lead time (diagnosis time advanced by screening), probability of over-diagnosis, etc., are functions of these three. Therefore accurate estimation of these three key parameters is critical and lays a foundation for all other estimations.

Servo valve is the key element in electropneumatic servomechanism. In this study, an electropneumatic two-stage servo valves were investigated in order to improve their static and dynamic characteristics. These servo valves consist of a pilot stage and a power stage. The paper discusses three different pilot stages: the jet pipe pilot stage, the supply (side) flapper nozzle pilot stage and the exhaust (side) flapper nozzle pilot stage. The static and dynamic characteristics of the devices were investigated analytically and by computer simulation. For the three pilot stage types it was found that the optimal value of the static and dynamic characteristics could be obtained if the ratio between the effective areas of the supply channel and exhaust port of the pilot stage has a definite value (depending on the pilot stage type).

Full textAbstract:
This paper contributes to the strategic alliance literature by undertaking a literature review of the burgeoning strategic alliance literature published in the last three decades in the mainstream management journals to fulfil two primary objectives. First, to bring a coherent structure into the fairly vast and growing alliance literature and second, to serve as a medium for a holistic understanding of the major life stages of strategic alliances. This is done by first dividing the alliance literature into three distinct yet related alliance life stages namely the pre-alliance stage, alliance formation stage and the alliance management and performance stage, and then by discussing in detail the three alliance stages individually. The paper would be useful for academics as well as practitioners looking to get a holistic understanding of strategic alliances and its three distinct yet related life stages and the key research papers which have been published focussing on each of these alliance stages.

Full textAbstract:
Background: Hosta plantaginea (Lam.) Aschers (HPA), a species in the family Liliaceae, is an important landscaping plant and herbaceous ornamental flower. However, because the flower has only two colors, white and purple, color matching applications are extremely limited. To date, the mechanism underlying flower color regulation remains unclear. Methods: In this study, the transcriptomes of three cultivars—H. plantaginea (HP, white flower), H. Cathayana (HC, purple flower), and H. plantaginea ‘Summer Fragrance’ (HS, purple flower)—at three flowering stages (bud stage, initial stage, and late flowering stage) were sequenced with the Illumina HiSeq 2000 (San Diego, CA, USA). The RNA-Seq results were validated by qRT-PCR of eight differentially expressed genes (DEGs). Then, we further analyzed the relationship between anthocyanidin synthase (ANS), chalcone synthase (CHS), and P450 and the flower color regulation by Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Eukaryotic Orthologous Groups (KOG) network and pathway enrichment analyses. The overexpression of CHS and ANS in transgenic tobacco petals was verified using qRT-PCR, and the petal colors associated with the overexpression lines were confirmed using absorbance values. Results: Over 434,349 transcripts were isolated, and 302,832 unigenes were identified. Additionally, through transcriptome comparisons, 2098, 722, and 606 DEGs between the different stages were found for HP, HC, and HS, respectively. Furthermore, GO and KEGG pathway analyses showed that 84 color-related DEGs were enriched in 22 pathways. In particular, the flavonoid biosynthetic pathway, regulated by CHS, ANS, and the cytochrome P450-type monooxygenase gene, was upregulated in both purple flower varieties in the late flowering stage. In contrast, this gene was hardly expressed in the white flower variety, which was verified in the CHS and ANS overexpression transgenic tobacco petals. Conclusions: The results suggest that CHS, ANS, and the cytochrome P450s-regulated flavonoid biosynthetic pathway might play key roles in the regulation of flower color in HPA. These insights into the mechanism of flower color regulation could be used to guide artificial breeding of polychrome varieties of ornamental flowers.

Full textAbstract:
This paper presents a saving-based heuristic for the vehicle routing problem with time windows and stochastic travel times (VRPTWSTT). One of the basic ideas of the heuristic is to advance the latest service start time of each customer by a certain period of time. In this way, the reserved time can be used to cope with unexpected travel time delay when necessary. Another important idea is to transform the VRPTWSTT to a set of vehicle routing problems with time windows (VRPTW), each of which is defined by a given percentage used to calculate the reserved time for customers. Based on the above two key ideas, a three-stage heuristic that includes the “problem transformation” stage, the “solution construction” stage, and the “solution improvement” stage is developed. After the problem transformation in the first stage, the work of the next two stages is to first construct an initial solution for each transformed VRPTW by improving the idea of the classical Clarke-Wright heuristic and then further improve the solution. Finally, a number of numerical experiments are conducted to evaluate the efficiency of the described methodology under different uncertainty levels.

Long range scanning stages with very small positioning errors are the key elements in the nano-CMM that is used to determine the sizes and coordinates of micromachines and parts in three dimensions to realize MEMS/nano technology. A transmission stage needs six degree-of-freedom precision motion controls. A compact critical angle sensor (CAS) can be mounted on the base or frame to be used to monitor the orientation parameters of the scanning/transmission stage along the 3 axes and feedback the error signal of the sensor output to maintain the stage moving performance. By calibration with an autocollimator, the resolution is better than 0.1 arcsec with a measurement range above 600 arcsec.

Full textAbstract:
Various security threats are encountered when keys are transmitted in public channels. In this paper, we propose an image encryption algorithm based on complex network scrambling and multi-directional diffusion. Combining the idea of public key cryptography, the RSA algorithm is used to encrypt the key related to plaintext. The algorithm consists of three stages: key generation stage, complex network scrambling stage, and multi-directional diffusion stage. Firstly, during the key generation phase, SHA-512 and the original image are used to generate plaintext-related information, which is then converted to plaintext-related key through transformation mapping. Secondly, in the complex network scrambling stage, the chaotic random matrix establishes the node relationships in the complex network, which is then used to construct an image model based on the complex network, and then combines pixel-level and block-level methods to scramble images. Finally, in the multi-directional diffusion stage, the multi-directional diffusion method is used to perform forward diffusion, middle spiral diffusion, and backward diffusion on the image in turn to obtain the final ciphertext image. The experimental results show that our encryption algorithm has a large keyspace, the encrypted image has strong randomness and robustness, and can effectively resist brute force attack, statistical attack, and differential attack.

Full textAbstract:
Oil shale is a kind of high-combustion heat mineral, and its oxidation in mining and storage are worth studying. To investigate the low-temperature oxidation characteristics of oil shale, the temperature, CO, alkane and alkene gases were analyzed using a temperature-programmed device. The results showed that the temperature of oil shale underwent three oxidation stages, namely a slow low-temperature oxidation stage, a rapid temperature-increasing oxidation stage, and a steady temperature-increasing stage. The higher the air supply rate is, the higher the crossing point temperature is. Similar to coal, CO also underwent three stages, namely a slow low-temperature oxidation stage, a rapid oxidation stage, and a steady increase stage. However, unlike coal, alkane and alkene gases produced by oil shale underwent four stages. They all had a concentration reduction stage with the maximum drop of 24.20%. Statistical classification of inflection temperature of various gases as their concentrations change showed that the temperature of 140 °C is the key temperature for group reactions, and above the temperature of 140 °C, all alkane and alkene gases underwent the rapid concentration increase stage.

Firstly a three degrees of freedom micro-positioning stage constructed by flexure hinges is designed, and the simplified model of the stage is established. Secondly, the stiffness of the stage along X, Y direction or around Z direction is deduced by structural mechanics. The difference between finite element method and theory value is less than 7%, so it shows the theory analysis is feasible, further more, stress of the moving stage is analyzed, and the effect curve of the key parameters to the stiffness and stress is obtained. It can be concluded that the stiffness and stress mainly related with the flexure hinge length L and width t, thus it provide a theoretical basis for three-dimensional micro-positioning stage design.

The present study investigated the fruits of aronia (Aronia melanocarpa) across different stages of maturity and analyzed their physicochemical properties, antioxidant compositions, and activities. The selected aronia cultivars (‘Viking’, ‘McKenzie’, and ‘Kingstar K1’ were categorized based on maturity into the immature stage (red tip), intermediary stage (red), and mature stage (dark purple). The key sugar components of aronia fruits were fructose, glucose, and sorbitol, while the main organic acid was found to be malic acid. The antioxidant content and activity of all three aronia cultivars showed significantly higher values for the red tip stage than the red or dark purple stages. However, the total anthocyanin content of aronia was the highest at the dark purple stage in three cultivars. The main polyphenols in aronia fruits were found to be catechol and chlorogenic acid, with a decreasing tendency as maturation progressed. As a result, the red tip stage of aronia fruits contains comparatively more abundant flavonoids, phenolic compounds and polyphenols than the dark purple stage, with higher antioxidant activity.

Accurate prediction of hydrological processes is key for optimal allocation of water resources. In this study, two novel hybrid models are developed to improve the prediction precision of hydrological time series data based on the principal of three stages as denoising, decomposition, and decomposed component prediction and summation. The proposed architecture is applied on daily rivers inflow time series data of Indus Basin System. The performances of the proposed models are compared with traditional single-stage model (without denoised and decomposed), the hybrid two-stage model (with denoised), and existing three-stage hybrid model (with denoised and decomposition). Three evaluation measures are used to assess the prediction accuracy of all models such as Mean Relative Error (MRE), Mean Absolute Error (MAE), and Mean Square Error (MSE). The proposed, three-stage hybrid models have shown improvement in prediction accuracy with minimum MRE, MAE, and MSE for all case studies as compared to other existing one-stage and two-stage models. In summary, the accuracy of prediction is improved by reducing the complexity of hydrological time series data by incorporating the denoising and decomposition.

ABSTRACT Based on the four major challenges firms face in the early stage of their life cycle, we identify and use financial and non-financial performance measures to predict the survivability of new international ventures. We use a sample of 3,729 new manufacturing ventures from the Chinese Foreign Invested Enterprises Database. The study sample consists of wholly owned ventures of multi-national corporations (MNCs) and joint ventures between pairs comprising foreign and local investors in China. The results are consistent with the study's hypotheses. Using the Cox (1972) survival model, we find that employee training, employee productivity, accounts receivable collection period, export intensity, and sales growth are positively related to new venture survival. This study contributes to the existing business venturing and accounting literature in three ways. First, it fills the gap in the existing literature on bankruptcy prediction by focusing on firms in the early stage of their life cycle. Second, it uses survivability as a measure of business success. Survivability is a more comprehensive measure of firm performance than traditional financial measures during the start-up stage because during this stage firms tend to carry large losses that make financial measures inappropriate. Finally, this study has the potential to help new venture managers improve a firm's chances of success by using customized performance measures that fit its unique situation.

Full textAbstract:
The security of Quantum Secure Direct Communication (QSDC) and its authentication procedure based on multiple stages is analyzed. The security analysis shows that the process of authentication is required to be done three times based on the usage of unitary transformation that is only known between Alice and Bob. In the proposed protocol, a secure quantum handshake is utilized to share the secret polarization angle and an authentication key at the initial stage of authentication over the quantum channel. The symmetry key is used in this work to protect user data communication within the QSDC protocol, where the same secret key is used to encrypt and decrypt the message. This work adopts the information travel time (ITT) by allowing the sender to detect any interference from third parties. In addition, the operation of the Pauli-X quantum gate increases Eve’s difficulty in stealing the information. The information transmitted is then continued by sending photons once in the quantum channel, which improves the efficiency without losing the message’s security. In addition, to securely transfer the stream of messages, the proposed protocol is operated in single-stage, and the authentication is applied bit-by-bit, thus reducing the transmission time. Security checks are carried out along the data transmission process. Compared to previous protocols, this new initial authentication protocol has remarkable advantages since it does not require public communication to pre-share the authentication key and secret angles before the onset of the transmission, therefore, reducing the communication cost. Moreover, the secret authentication key and polarization angles are updated after a number of bits are sent to increase the security level. The verification process is also conducted to ensure the symmetry of the sender and receiver. The analyses presented herein demonstrate that the proposed authentication protocol is simple and secure in order to ensure the legitimacy of the users.

The Taizhou Yangtze river bridge is a suspension bridge with three pylons and two 1080m long navigation spans. The middle pylon with height 191.5m is made of steel. The general construction procedure of the middle steel pylon is briefly introduced. Construction control of the pylon is carried out during the whole process of the construction. The control concept is extended to the manufacture stage besides the installation stage. The manufacturing alignment errors are strictly controlled in precast process of the segments in factory, and the alignment error is identified and predicted precisely during the installation stage. The adjusting joints are adopted to adjust the accumulated errors, which ensure that the steel pylon alignment could satisfy the as-built precision requirements.

Background literature hints that the transition corresponds to the transformation of the rhombic form of elemental sulphur to the more reactive monoclinic form that occurs at 96 °C. A test apparatus is modified for adiabatic heating to track the transition. The results support this transformation of sulphur as being key to the transition, and the transition temperature is thus modified to 96 °C. Variations in a sample’s response under adiabatic conditions are observed and possible reasons are discussed. Testing in adiabatic mode provides new insights into the sulphide self-heating process that complements the test designed to identify propensity to self-heat.

Full textAbstract:
Crushing performance is being widely investigated because it is the key performance indicator of the thin-walled beam structure in automobile safety components. In this study, five kinds of ageing state with different yield strengths were prefabricated with a self-developed KHC63 alloy. Using a rectangular tube profile, the physical relationship between crushing properties and mechanical properties, and the structure of the profile, were studied. According to variation characteristics, the crushing curve was divided into four typical stages: elastic stage, bending stage, compaction stage and folding stage. In the elastic stage, the peak load of the component is related to material elasticity and structure elasticity, and the relationship is approximately linear. In the bending stage, the driving factor of plastic hinge deformation is the bending moment, and it is always constant. In the compaction stage, the crushing curve correlates well with the cosine function. In the folding stage, the crushing process begins to lose stability and is hard to predict. The mathematical relationships between force and displacement were established according to the characteristics of each stage, and the calculated results were close to the measured results except for the folding stage. The deviation of the calculated energy absorption from the measured data in the first three stages is only 4.3%, but it is 10.6% in the folding stage. The calculation method used for the first three stages is, therefore, suitable.

A qualitative comparative analysis." Implementation Research and Practice 3 (January 2022): 263348952211126. http://dx.doi.org/10.1177/26334895221112694.
Full textAbstract:
Background Coalitions are increasingly utilized to promote positive community health outcomes. Typically, coalitions produce more desirable outcomes when coalition functioning is strong and the coalition model is implemented with fidelity. Although theory indicates that coalitions proceed through predictable stages of development, minimal research explicitly examines functioning and fidelity at these different stages. Method Within a larger evaluation of Washington State Community Prevention and Wellness Initiative, this cross-sectional study employs qualitative comparative analysis to illuminate the coalition functioning conditions necessary and sufficient to produce high model fidelity at different stages of development in 43 substance misuse prevention coalitions in one state. Results In the formation stage, only the presence of high levels of coalition leadership was sufficient to produce high model fidelity. In the maintenance stage, three combinations of conditions were sufficient: (1) sustainability planning if, and only if, accompanied by the absence of coalition participation costs, (2) coordinator leadership, and (3) a combination of coalition leadership and team cohesion. In the institutionalization stage, two solutions were sufficient: (1) coalition leadership if, and only if, accompanied by the absence of sustainability planning, and (2) sustainability planning if, and only if, accompanied by the absence of coordinator leadership. Conclusions This study illustrates several tangible steps technical assistance providers may take to increase the likelihood of achieving model fidelity. In the formation stage, skillful and inclusive coalition leadership is important. In the maintenance stage, technical assistance should focus on reducing participant-perceived costs; increasing sustainability planning; enhancing coordinator-specific leadership; and developing team cohesion and coalition leadership. For coalitions in the institutionalization stage, coalition leadership and sustainability planning may be prime targets for technical assistance. Plain Language Summary: Community coalition approaches to addressing social problems are common and have some evidence of producing positive community outcomes. Research shows that coalitions produce more desirable outcomes when coalition functioning is strong and the coalition model is implemented as it was designed. Although theory suggests that coalitions proceed through predictable stages of development, few studies look at which supports are most needed, at each stage, to improve coalition functioning and implementation. This study aims to help answer that question by determining which aspects of coalition functioning, in which combinations, are key to strong, well-functioning coalitions at different developmental stages in a sample of prevention coalitions in Washington State focused on youth substance misuse. The results suggest that having a strong coalition leadership team is key for all coalitions, regardless of development stage. For coalitions earlier in their formation, this was especially true. For coalitions further into their development, the combination of strong coordinator leadership and strong team cohesion was particularly important. Finally, for the most well-established coalitions, if sustainability planning was weak, strong coalition team leadership was key; but if coordinator leadership was weak, strong sustainability planning was critical to offset the lack of strong leadership. The results can be used to inform the types of technical assistance provided to support coalitions at different developmental stages.

Full textAbstract:
The subject of this research is the fundamental positions and concepts of installation discourse, i.e. key texts that are dedicated to installation and formed representation on this artistic practice. Installation discourse has emerged in the West in the early 1960’s, and presently there can be determined the “anchor points, “objective concepts”, main positions and vectors of installation analysis. Elements of the discourse include academic monographs, such as art criticism, texts of artists, and exhibition catalogues. The article employs the methods of discourse analysis of E. Laclau, C. Mouffe, N. Fairclough, as well as general discourse theory of M. Foucault described in the “Archeology of Knowledge”. The conducted discourse analysis allows making the following conclusions. The three main vectors of installation discourse can be associated with three “turns” of philosophy and humanistic thought of the XX century – phenomenological, linguistic and performative. Discourse analysis allows tracing the meanings imposed on the “anchor points” in various vectors of the discourse. Discourse analysis gives a perspective on the “objective concepts” of discourse that underlie the understanding of installation at the present stage – “theatricality”, “indermediality”, “unlocked”, anti-object character of installation, site-specificity; institutional criticism, multisensority and ephemerality.

Full textAbstract:
Transcriptional regulation is pivotal to the specification of distinct cell types during embryonic development. However, it still lacks a systematic way to identify key transcription factors (TFs) orchestrating the temporal and tissue specificity of gene expression. Here, we integrated epigenomic and transcriptomic data to reveal key regulators from two cells to postnatal day 0 in mouse embryogenesis. We predicted three-dimensional chromatin interactions in 12 tissues across eight developmental stages, which facilitates linking TFs to their target genes for constructing transcriptional regulatory networks. To identify driver TFs, we developed a new algorithm, dubbed Taiji, to assess the global influence of each TF and systematically uncovered TFs critical for lineage-specific and stage-dependent tissue specification. We have also identified TF combinations that function in spatiotemporal order to form transcriptional waves regulating developmental progress. Furthermore, lacking stage-specific TF combinations suggests a distributed timing strategy to orchestrate the coordination between tissues during embryonic development.

This study is concerned with benchmarking the hotel industry in the Sultanate of Oman besides identifying the environmental factors that influence the operational efficiency of hotels. The benchmarking analysis is carried out through data envelopment analysis (DEA), used essentially to evaluate the efficiency ratios of a selected sample of 58 hotels. Although less than 23% of the hotels are found efficient, the average efficiency score of 83% indicates a reasonable efficiency in resource management for most of the hotels. Regarding the contextual effects, hotel Size, Star rating and cultural attractions are found to have the most significant effect on hotel efficiency in Oman. The positive effect of cultural attractions can inform policy makers on the necessity to preserve and promote cultural heritage as an important key factor of attraction.

Full textAbstract:
Movable retaining pins are generally used in automobile gears, axles, crankshafts, and seatbelt assemblies. The original manufacturing procedures comprise three-stage forming and then drilling. However, a clamp in the drilling process always causes rod surface damage and dents, and the resulting depth tolerance that always exceeds specified dimensions. This study modifies the cold-forging process by replacing the original mechanical drilling stage with one additional forming stage comprised of backward extrusion. The finite element method is applied to analyze and simulate the forming load at each stage, and the Taguchi method is utilized to optimize the product quality in the key second stage. Analytical results show that transforming the original three forging processes and one drilling process into four forging stages overcomes the problems in part manufacturing. Simultaneously, the dimensional accuracy obtained from experiment and numerical analyses shows in good agreement and trusty.

PeerJ 6 (June 14, 2018): e4945. http://dx.doi.org/10.7717/peerj.4945.
Full textAbstract:
Cotton plant architecture, including fruit branch formation and flowering pattern, influences plant light exploitation, cotton yield and planting cost. DNA methylation has been widely observed at different developmental stages in both plants and animals and is associated with regulation of gene expression, chromatin remodelling, genome protection and other functions. Here, we investigated the global epigenetic reprogramming during the development of fruiting branches and floral buds at three developmental stages: the seedling stage, the pre-squaring stage and the squaring stage. We first identified 22 cotton genes which potentially encode DNA methyltransferases and demethylases. Among them, the homologous genes of CMT, DRM2 and MET1 were upregulated at pre-squaring and squaring stages, suggesting that DNA methylation is involved in the development of floral buds and fruit branches. Although the global methylation at all of three developmental stages was not changed, the CHG-type methylation of non-expressed genes was higher than those of expressed genes. In addition, we found that the expression of the homologous genes of the key circadian rhythm regulators, including CRY, LHY and CO, was associated with changes of DNA methylation at three developmental stages.

Full textAbstract:
The relationship of sedimentary organic matter, oil-gas and sandstone-type uranium (U) deposits is the key problem of U-mineralization. Whether migrate hydrocarbons participate in U-mineralization is still a controversy. Typical U deposits of the Erlian Basin in northeast China have been investigated through detailed petrography, mineralogical, micro spectroscopic, organic geochemical and C-isotope studies. Petrographic observations, Microscopic Laser Raman Spectroscopic, Infrared Spectroscopic and Scanning Electron Microscope analyses indicated there are three types of organic matter (including carbonaceous debris and migrated hydrocarbons). A significant amount of uranium was associated with pyrites, clay minerals and carbonaceous debris organic matter, either coexisted with hydrocarbon fluids. There are at least two stages mineralization events, stage I is related to sedimentary organic matter (syngenetic pre-enrichment stage), and stage II is related to mobile hydrocarbon fluids (main mineralization stage). Therefore, our results support that migrated hydrocarbons were involved as a reducing agent for the main uranium mineralization after synsedimentary mineralization.

The main goal of the investigation is to determine key technological parameters, necessary for producing required curvature of sheets up to 4000 mm in width with the required mechanical properties. Investigation into dynamics of the process' main technological parameters allowed it to define its three characteristic stages: asymmetric rolling, asymmetric rolling in combination with initial unsettled plastic bending, and asymmetric rolling combined with settled plastic bending. It was found out that the intensity of the deformations changes unevenly, depending on the height of the deformation zone, on all three stages, with its highest value being in the lower part of the sheet, and with the lowest value being in its center. In the second stage, the intensity of the deformation abruptly increases, and a significant asymmetry on the sheet thickness occurs. In the third stage, the non-uniformity of the intensity deformations fields decreases. Similar results can be also observed for stress intensities. Casings on two converters were produced and installed in the oxygen-converter plant.

The aim of this study was to describe and identify the weight of some key career indicators (KCI) on the competitive level of retirement (professional vs. non-professional) of Portuguese football players. Three thousand five hundred retired Portuguese football players born between 1950 and 1989, and registered on Portuguese Football Federation were considered in this study. Descriptive analysis and a multivariable binary logistic regression model were performed to assess the relationship between the mastery stage development variables and the competitive level of retirement of football players. The results highlighted that the KCI first senior registration level, number of seasons in mastery stage, number of total games as senior player, number of total games in retirement season, and the age of the last best result achieved contribute to explain and predict the competitive level of retirement of Portuguese football players. The tendencies identified and their impact on the competitive level of retirement could be important implications on awareness and definition of management and support programs of players’ careers.

Full textAbstract:
Background Colorectal cancer (CRC) is a leading cause of cancer-related deaths, with a 5% 5-year survival rate for metastatic disease, yet with limited therapeutic advancements due to insufficient understanding of and inability to accurately capture high-risk CRC patients who are most likely to recur. We aimed to improve high-risk classification by identifying biological pathways associated with outcome in adjuvant stage II/III CRC. Methods and findings We included 1062 patients with stage III or high-risk stage II colon carcinoma from the prospective three-arm randomized phase 3 AVANT trial, and performed expression profiling to identify a prognostic signature. Data from validation cohort GSE39582, The Cancer Genome Atlas, and cell lines were used to further validate the prognostic biology. Our retrospective analysis of the adjuvant AVANT trial uncovered a prognostic signature capturing three biological functions—stromal, proliferative and immune—that outperformed the Consensus Molecular Subtypes (CMS) and recurrence prediction signatures like Oncotype Dx in an independent cohort. Importantly, within the immune component, high granzyme B (GZMB) expression had a significant prognostic impact while other individual T-effector genes were less or not prognostic. In addition, we found GZMB to be endogenously expressed in CMS2 tumor cells and to be prognostic in a T cell independent fashion. A limitation of our study is that these results, although robust and derived from a large dataset, still need to be clinically validated in a prospective study. Conclusions This work furthers our understanding of the underlying biology that propagates stage II/III CRC disease progression and provides scientific rationale for future high-risk stratification and targeted treatment evaluation in biomarker defined subpopulations of resectable high-risk CRC. Our results also shed light on an alternative GZMB source with context-specific implications on the disease’s unique biology.

Full textAbstract:
During the breeding progress, screening excellent wheat varieties and lines takes lots of labor and time. Moreover, different climatic conditions will bring more complex and unpredictable situations. Therefore, the selection efficiency needs to be improved by applying the proper selection index. This study evaluates the capability of CTD as an index for evaluating wheat germplasm in field conditions and proposes a strategy for the proper and efficient application of CTD as an index in breeding programs. In this study, 186 bread wheat varieties were grown in the field and evaluated for three continuous years with varied climatic conditions: normal, spring freezing, and early drought climatic conditions. The CTD and photosynthetic parameters were investigated at three key growth stages, canopy structural traits at the early grain filling stage, and yield traits at maturity. The variations in CTD among varieties were the highest in normal conditions and lowest in spring freezing conditions. CTD at the three growing stages was significantly and positively correlated for each growing season, and CTD at the middle grain filling stage was most significantly correlated across the three growing seasons, suggesting that CTD at the middle grain filling stage might be more important for evaluation. CTD was greatly affected by photosynthetic and canopy structural traits, which varied in different climatic conditions. Plant height, peduncle length, and the distance of the flag leaf to the spike were negatively correlated with CTD at the middle grain filling stage in both normal and drought conditions but positively correlated with CTD at the three stages in spring freezing conditions. Flag leaf length was positively correlated with CTD at the three stages in normal conditions but negatively correlated with CTD at the heading and middle grain filling stages in spring freezing conditions. Further analysis showed that CTD could be an index for evaluating the photosynthetic and yield traits of wheat germplasm in different environments, with varied characteristics in different climatic conditions. In normal conditions, the varieties with higher CTDs at the early filling stage had higher photosynthetic capacities and higher yields; in drought conditions, the varieties with high CTDs had better photosynthetic capacities, but those with moderate CTD had higher yield, while in spring freezing conditions, there were no differences in yield and biomass among the CTD groups. In sum, CTD could be used as an index to screen wheat varieties in specific climatic conditions, especially in normal and drought conditions, for photosynthetic parameters and some yield traits.

Fig (Ficus carica L.), a deciduous fruit tree of the Moraceae, provides ingredients for human health such as anthocyanins. However, little information is available on its molecular structure. In this study, the fig peels in the yellow (Y) and red (R) stages were used for transcriptomic analyses. Comparing the R with the Y stage, we obtained 6224 differentially expressed genes, specifically, anthocyanin-related genes including five CHS, three CHI, three DFR, three ANS, two UFGT and seven R2R3-MYB genes. Furthermore, three anthocyanin biosynthetic genes, i.e., FcCHS1, FcCHI1 and FcDFR1, and two R2R3-MYB genes, i.e., FcMYB21 and FcMYB123, were cloned; sequences analysis and their molecular characteristics indicated their important roles in fig anthocyanin biosynthesis. Heterologous expression of FcMYB21 and FcMYB123 significantly promoted anthocyanin accumulation in both apple fruits and calli, further suggesting their regulatory roles in fig coloration. These findings provide novel insights into the molecular mechanisms behind fig anthocyanin biosynthesis and coloration, facilitating the genetic improvement of high-anthocyanin cultivars and other horticultural traits in fig fruits.

The increase in car market 17% in 2020, and ASEAN Free Trade policy only 5% for imported products, cause tightened competition in the automotive market. Car manufacturing companies face problems in selecting their performance indicators related to competitive challenges. The purpose of this research is to develop productivity key performance indicators in car manufacturing that conform to stakeholder requirements as a strategy to win the market. The conditions are manifested in a mapping of manufacturing symbols using the Integrated Performance Measurement System (IPMS) method. That manufacturing productivity indicators will become the focus of the top management to be controlled. There are four stages to go through, starting with the identification of stakeholder requirement, which produces six criteria and 12 stakeholder requirements and mapped into 16 goals and 24 key performance indicator (KPI). The second stage is benchmarking, and preparation of KPI hierarchy and the third stage is the description of each KPI in the form of KPI specification table. The fourth stage is the weighting of the six main criteria that result in 3 priority criteria which must be reported monthly between the manufacturing division (painting), finance and administration. Those are employee safety, manufacturing process effectiveness (painting) and waste elimination activities. The priority is obtained based on questionnaires answered by ten stakeholders (experts) processed with Analytical Hierarchy Process (AHP) approach and has been tested consistency in the number 0.09. These three criteria are described in 15 KPIs: performance rate, availability rate, quality rate, trained operator ratio, training value ratio> 80, delay ratio, attendance ratio, downtime losses, setup and adjustment losses, idle time, defect losses, yield losses, manpower efficiency, environmental impact and work accident ratio.

The low fiber digestibility and unbalanced amino acids restricted the use of DDGS in swine diets. Key nutrition components dynamic monitoring and key regulatory pathways analysis were performed to find the rules of nutrition changes for DDGS fermented by Aspergillus niger. Cellulose and hemicellulose were reduced to 15.3% and 15.2%. 1,4-D-Xylobiose was decreased from 16.8 μg/mL to 0.2 μg/mL. Lys, Arg, and Thr were increased to 3.00%, 2.89%, and 4.40%, and met the requirements of pigs. The whole fermentation process was divided into three stages. Cellulose degradation and Lys and Arg synthesis occurred in the early stage, while Asp synthesis occurred in the last stage. α-Ketoglutarate was the key factor for Aspergillus niger degrading cellulose to synthesize Lys and Arg. The key active metabolic pathways that respond to the changes in nutrition were identified which preliminarily revealed the rules of nutrition adjustment of DDGS during fermentation with Aspergillus niger.

CID has been proposed to indirectly select for transpiration efficiency and seed yield in C3 plants. Before using CID as an indirect selection criterion it is important for plant breeders to determine the best growth stage at which to sample for CID. Consequently, to determine the most effective growth stage to select for CID we measured: (i) several growth stages to determine the one that provides the maximum differential for CID, (ii) the magnitude of the genotype by growth stage interaction for CID, and (iii) the variability for CID within and among genotypes of two divergent genotypes of lentil (Lens culinaris Medikus), spring wheat (Triticum aestivum L.) and canola (Brassica napus L.). Three plants per pot were grown hydroponically in a glasshouse using a RCBD replicated four times. Three samples were collected at four growth stages: early vegetative, late vegetative, flowering and maturity. The variability for CID among plants within genotypes was small. The two lentil genotypes differed significantly in CID; whereas, no significant differences were observed for the wheat or canola genotypes. In all three crops the genotype by growth stage interaction for CID was not significant, and the best differential for CID among lentil genotypes was mature seed. The ranking of genotypes remained constant across growth stages; therefore, sampling for CID may be done at any stage of plant development. Key words: Carbon isotope discrimination, lentil, spring wheat, canola, growth stages.

Full textAbstract:
American trypanosomiasis is a chronic and endemic disease which affects millions of people.Trypanosoma cruzi, its causative agent, has a life cycle that involves complex morphological and functional transitions, as well as a variety of environmental conditions. This requires a tight regulation of gene expression, which is achieved mainly by post-transcriptional regulation. In this work we conducted an RNAseq analysis of the three major life cycle stages ofT. cruzi, amastigotes, epimastigotes and trypomastigotes. This analysis allowed us to delineate specific transcriptomic profiling for each stage, and also to identify those biological processes of major relevance in each state. Stage specific expression profiling evidenced the plasticity ofT. cruzito adapt quickly to different conditions, with particular focus on membrane remodeling and metabolic shifts along the life cycle. Epimastigotes, which replicate in the gut of insect vector, showed higher expression of genes related to energy metabolism, mainly Krebs cycle, respiratory chain and oxidative phosphorylation related genes, and anabolism related genes associated to nucleotide and steroid biosynthesis; also a general down-regulation of surface glycoproteins was seen at this stage. Trypomastigotes, living extracellularly in the bloodstream of mammals, express a plethora of surface proteins and signaling genes involved in invasion and evasion of immune response. Amastigotes mostly express membrane transporters and genes involved in regulation of cell cycle, an also express a specific subset of surface glycoproteins coding genes. In addition, these results allowed us to improve the annotation of Dm28c genome, identifying new ORFs and set the stage for construction of networks of co-expression, which can give clues about coded proteins of unknown functions.

Full textAbstract:
There is a body of evidence that shows that early education improves cognitive and social development for children while they are still attending, but the longer-term impacts depend on the quality of early education. Much of this evidence in England relates to a period when attendance rates at early education were around 60 per cent. Since then, early education has expanded through the guarantee of free provision for three- and four-year-olds, such that attendance at early education is now almost universal. This paper uses data from the Millennium Cohort Study to consider whether, in an era of near universal provision, early education is still associated with detectable improvements in outcomes for children. The analysis focuses on attainment in Key Stage 1 assessments when children were aged seven and finds that the overall impact of early education on Key Stage 1 attainment is modest, but that the impact is generally greater for those children who experienced poverty when they entered early education.

Full textAbstract:
The study of network relationship using UCINET program in part 1 was inspired by the problematicfragmented structure of a construction project development team. In this paper, the multi-stage projectdevelopment process as another key factor that underlies the construction industry’s poor performance isaddressed. Knowledge management is then proposed as another key solution to achieve the more effectiveproject development in Thailand context. Based on Nonaka and Takeuchi’s 1995 knowledge conversion model,representatives from key project members’ organisations that developed recently complete large commercialresidential projects in Bangkok central business area were asked in semi-structured interviews aboutorganisational knowledge management process using a set of standardised questions. The outcomes show themoderate efficiency due to key project members’ unawareness of knowledge potentials. A three-stage frameworkis also proposed to identify key project members, strengthen network relationship and improve organisationalknowledge management capability to achieve the better project development performance.
