La investigación que se presenta es un primer acercamiento al estudio del nivel de competencia digital autopercibida de los estudiantes universitarios en el contexto latinoamericano con una muestra representativa de 5 países de la región. Para la recogida de datos se ha utilizado el instrumento INCOTIC adaptado para el contexto Latinoamericano. Las variables objeto de estudio son: la alfabetización Informacional (DAI), la alfabetización tecnológica (DAT), la alfabetización multimedia (DAM) y la alfabetización comunicativa (DAC); analizando los datos por países y comparando los resultados para cada uno de ellos en función de la edad y el género. Se detecta que el país que menor puntuación obtiene en las alfabetizaciones analizadas es Ecuador, siendo Chile y Colombia los países con mejor puntuación. Además, se observan interesantes diferencias al profundizar por género y edad en cada alfabetización. En concreto, la DAI más alta se da en el rango de edad entre los 24-31 años, y la DAT, DAM y DAC se da en el rango de 28-31 años. En el caso de las mujeres, la DAI más alta se da en el rango de edad entre los 20-27 años, y la DAT, DAM y DAC se da en el rango de 28-31 años. Se espera diseñar las líneas maestras de un Plan de Alfabetización Digital para estudiantes universitarios con propuestas para cada una de las universidades participantes que luego sea el insumo para que los investigadores de cada país puedan contextualizarlos a sus realidades con énfasis en las competencias informacionales, por la importancia que ellas tienen en la prosecución de estudios universitarios y posterior desempeño laboral.

Abstract Tai Dam [blt] is a Southwestern Tai (< Kra-Dai) language spoken in Vietnam, Laos, China, and Thailand with approximately 750,000 speakers (Simons & Fennig 2017). The Tai Viet script has been used for centuries to write Tai Dam and other Tai languages. Because the Tai Viet script is not taught in schools, however, some Tai Dam readers prefer to use adaptations of the Vietnamese and Lao orthographies for writing Tai Dam. This paper describes Tai Dam orthographies in the Tai Viet, Lao, and Roman scripts. Particular focus is given to the way writers have faced the challenge of tonal mismatch between Tai Dam and Vietnamese or Lao by borrowing tone marking devices from one script to another, and to the sociolinguistic implications of these tone marking systems.

The objective of this study was to validate the shelf-life of marinated and frozen chicken tenderloins. Treatments were randomly assigned to the age of the tenderloins post-harvest, days aged (DA): DA4, DA5, DA6, DA7, and DA8. Microbial analyses were used to analyze the growth of aerobic, psychotropic, and lactobacilli bacteria to assess the shelf-life of bulk-packaged chicken tenderloins. Tenderloins were sampled fresh, then vacuum tumbled in a marinade. After marination, the tenderloins were sampled with the remaining tenderloins packaged and frozen (−25 °C). After freezing the chicken tenderloins were slacked in a refrigerated cooler (2.2 °C) for up to 132 h (h) and sampled at 36 h, then every 24 h following. After marination, each treatment significantly (p < 0.05) decreased in aerobic and psychotropic counts except DA4. During slacking, no treatment crossed the threshold of 106 CFU/mL (Log 6) set for this study. Though none crossed the threshold, treatments DA4, DA5, and DA6 had significant (p < 0.05) increases in aerobic bacteria after 7 days of age. The psychotropic bacteria continuously grew at each sampling period, with DA4 and DA5 surpassing the other treatments (p < 0.05) at 108 h and 132 h reaching 105 CFU/mL. Every treatment remained below the spoilage threshold, suggesting that this method of storage is suitable for chicken tenderloin shelf-life.

As dams approach the end of their design life periods, retrofitting of dams is needed in many cases. For the retrofitting procedure of building a new dam close to the existing old dam without demolishing it, the interaction between the two dams and the unbounded foundation is an important issue to be investigated. The influence of the existing dam on the dynamic response of the newly built dam is examined. Two systems are analyzed, i.e., the new dam-foundation system and the dam-foundation-dam system. For the two systems, modal analysis and time history analysis using the viscous-spring artificial boundary are performed. It’s found that there’re much more vibration frequencies for the dam-foundation-dam system as compared to the new dam-foundation system within the same frequency range. The existence of the old dam also induces one more peak and a wider plateau in the response spectrum of the acceleration time history of the dam crest. However, the maximum stress distribution is not influenced much by the old dam.

Streszczenie:
In actual concrete arch dam engineering scenarios, the dynamic data obtained by the health monitoring system of an arch dam are incomplete. The data acquired typically depend on the state of the dam structure, that is, whether it is intact or incomplete. Besides, the future environmental loads of the structure are unpredictable. Thus, environmental noise is also uncertain. In practical engineering, the use of a damage identification model constructed based on incomplete information is problematic in scenarios with variable loads. Consequently, detecting the water level in actual arch dam projects after an earthquake and determining the impact of environmental uncertainty are necessary. Accordingly, this paper proposes a denoising contractive sparse deep autoencoder (DCS-DAE) model based on domain adaptation. The core idea of the proposed method is to constrain the data probability distribution of feature spaces in the source and target domains using maximum mean discrepancy. This fusion enables the DCS-DAE model to be capable of feature extraction. Moreover, it resolves the problem in which the objective function cannot be applied to other similar scenarios because of the lack of consistency constraints of feature spaces in the source and target domains. Four working conditions are designed to reproduce the uncertainty of structural modeling and the variability of water levels. The conditions are based on the postseismic water level detection requisites of dams in practical engineering. The results show that the proposed anomaly detection model enhances the generalization performance of the DCS-DAE in terms of feature design. Hence, the constructed model can “infer other things from one fact.” The results of this study are meaningful for the real-time cross-domain monitoring of structures under variable load conditions, providing a driving force to apply similar methods to practical arch dam projects.

The success of an upper complete denture is dependent on various factors, including retention and stability during function, comfort and aesthetics. Physical retention of the denture depends upon adequate extension and fit, along with a good border seal. The border seal of an upper denture relies upon extension of the flanges to the functional depth and width of the sulci, and the post-dam. The post-dam of an upper complete denture is a raised ‘lip’ along the posterior border that becomes embedded into the palatal mucosa. This ‘embedding’ of the border within the mucosa helps to create the seal. This technique tip highlights the location and shape of the post-dam, as well as the clinical stages involved in its construction. CPD/Clinical Relevance: Successful location and application of a post dam will help in retention of an upper complete denture.

Mosul Dam is located in the northwestern part of Iraq impounding the Tigris River; about 60 km north of Mosul city. This project is multipurpose project; to provide water for irrigation, flood control and hydropower generation. The dam is 113 m high and 3650 m long including the spillway. The dam is earth fill type with a mud core. The dam was designed to impound 11.11 km3 because it is based and underlain by gypsum beds alternated with limestone and marl. Therefore, it is planned to use continuous grouting to fill the karst caverns. The used quantity exceeded 95000 tons of solid grouting materials since 1986 up to 2014. After all, is the dam safe?

The Karolinka earth-fill dam was constructed between 1977 and 1984 on the Stanovnice river above the town of Karolinka in the region of Vsetínsko in Czech Republic. Because of leakage on the downstream dam face due to technological indiscipline when filling dam layers during the dam construction stage, there were some steps to improve state dam safety. The final rehabilitation is to construct the diaphragm walls from self-hardening cement-bentonite suspension along the length of the dam. In addition to connecting the gallery and abutment (2 × 25 m long) by using jet piles. The article presents numerical modeling of safety factor evaluation associated with the state of the dam body and foundation; before, and after sealing. Also, studying the effect of dam height on its stability by using finite element method is performed by the Plaxis 3D program in the case study of Karolinka dam. It is concluded that measured data shows good agreement with the computed result.

Abstract Introduction: After establishing the diagnosis of acute myeloid leukemia (AML), remission induction chemotherapy is started with curative intent. Due to paucity of direct therapeutic comparison of induction regimens, relative efficacy of two drug standard regimens and three drug induction regimens among newly diagnosed young (<60 years) AML patients is not established. We conducted a systematic review and network meta-analysis (NMA) of clinical trials that assessed relative effectiveness of standard two drug ("7+3 regimen") induction therapy (cytarabine 100-200 mg/m2 for 7 days + anthracycline for initial 3 days) or a three drug combination with other drugs ("7+3+X" regimen) tested as induction for complete remission (CR) in young patients with AML. Methods: The literature search was performed on PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science and Clinicaltrials.gov from each database's earliest inception through July 28th, 2018 without language restrictions. Included trials assessed CR after one cycle of induction chemotherapy in adults (17-60 years) diagnosed with AML. We excluded studies with patients ≥60 years, who received double induction chemotherapy or two drug regimens other than standard chemotherapy. Data extraction and quality assessment of trials using GRADE approach was done by two independent reviewers. Any discrepancy was resolved by consensus or consulting the primary investigators. A conventional NMA assuming random effects was fitted to evaluate the pooled effect of induction therapy on CR with standard chemotherapy as reference treatment. The model estimated relative efficacy for each direct and indirect comparison, measured as odds ratio (OR), with uncertainty captured as 95% confidence interval (CI). Chemotherapy regimens were ranked based on the surface under the cumulative ranking curve analysis (SUCRA) with higher values reflecting greater CR. All statistical analyses were conducted using STATA, version 15 (Stata Corp LP, College Station, TX). Results: Our analysis included 8 RCTs (n= 6830) including nine treatment regimens (7+3 or 7+3+X): cytarabine + daunorubicin (DA), cytarabine + idarubicin (IA), DA+ gemtuzumab ozogamicin (DAGo), DA+ 6-thioguanine (DAT), IA+ granulocyte colony stimulating factor (IAG), DA + midostaurin (DAM), DA + cladribine (DAC), DA + fludarabine (DAF), IA + cladribine (IAC). Average median age of included patients was 38.1 years (range = 45-60) and all patients had newly diagnosed primary AML. 10% had favorable cytogenetics, 62% intermediate and 27% had high risk cytogenetics. Through the network meta-analysis IA achieved highest CR rates [OR of 1.85 (95% C.I: 1.02-3.35)] compared to other included regimens (Figure 1). There was no statistically significant difference in achieving CR between anthracycline based standard chemotherapy versus three drug regimens [IAC = 0.85 (0.25-2.87), DAGo = 1.09 (0.75-1.59), DAF = 1.10 (0.73-1.63), DAT = 1.19 (0.78-1.82), DAM = 1.24 (0.88-1.77), DAC = 1.38 (1.00-1.90), AIG = 1.83 (0.90-3.75)] (Figure 2). A dose specific subgroup analysis of daunorubicin (60 mg/m2) containing regimens showed no statistical difference between different therapies [DAG = 1.09 (95% CI: 0.75-1.59), DAF = 1.10 (95% CI:0.73-1.63), DAM = 1.24 (0.88-1.77), DAC =1.38 (1.00-1.90)] (Figure 1). Conclusion: Our results demonstrate that combination of cytarabine with idarubicin achieved highest rates of CR after one cycle of induction therapy in newly diagnosed young AML patients. There was no statistical difference between the efficacy of other standard regimens and three drug regimens. Head-to-head trials are required to reliably demonstrate the relative efficacy of these regimens. Disclosures No relevant conflicts of interest to declare.

The objective of this study was to evaluate alternatives for modeling the interaction between age of dam at calving (AOD) and the dam genetic group (DGG) on the weaning weight (W225) of Charolais-Zebu (Ch-Z) crossbred calves. Data from 56,965 crossbred calves were analyzed by the least square method. Regression coefficients for age of dam at calving were estimated nested into each class of the dam genetic group (CLA model); for age of dam at calving × dam Charolais percentage (age of dam at calving × FCh) and age of dam at calving × dam heterozygosity (age of dam at calving × FH) (FChFH model); for age of dam at calving × dam Charolais percentage (FCh model); for age of dam at calving × FH (FH model); or only for age of dam at calving (NINT model). Segmented polynomials were used to model the general shape of the age of dam at calving effect and its interaction with dam genetic group. The knots were at 6.33 and 10.66 years of age of dam at calving and general linear and quadratic coefficient regression and specific quadratic coefficient regression after each knot were fitted. The regression coefficients were estimated nested within sex of the calf in all situations. According to the F test for sum of squared residuals differences, the inclusion of the age of dam at calving × FH interaction did not improve the fit of the model and the CLA model provided the best fit. However, the estimates of the age of dam at calving and dam genetic group interaction from the CLA model for dam genetic group × sex of the calf classes with few records were not appropriate, but the estimates of the age of dam at calving and dam genetic group interaction from the FCh model for those classes were appropriate. The differences were small in the estimates of the age of dam of calving and dam genetic group interaction from the CLA or FCh models for dam genetic group × sex of the calf classes with many records.

Lett. 2005, 87, 034101], where quality factors of the oscillating probe are inherently low, challenges some accepted beliefs concerning sensitivity and resolution in dAFM imaging modes. Through analysis and experiment we study the performance metrics for high-resolution imaging with dAFM in liquid media with amplitude modulation (AM), frequency modulation (FM) and drive-amplitude modulation (DAM) imaging modes. We find that while the quality factors of dAFM probes may deviate by several orders of magnitude between vacuum and liquid media, their sensitivity to tip–sample forces can be remarkable similar. Furthermore, the reduction in noncontact forces and quality factors in liquids diminishes the role of feedback control in achieving high-resolution images. The theoretical findings are supported by atomic-resolution images of mica in water acquired with AM, FM and DAM under similar operating conditions.

Dam construction has serious consequences for anadromous fishes. We examined the effects of migration barriers formed following dam construction on the migratory behavior of white-spotted char (Salvelinus leucomaenis) by comparing migrants in accessible below-dam river sections with migrants in inaccessible above-dam river sections. The frequency of smolts (i.e., potential migrant) was higher for the below-dam sections than for the above-dam sections, and in contrast, the frequency of residents was higher for the above-dam sections. Above-dam sections had lower fry (age 0+) densities and consequently had higher growth rates compared with below-dam sections. A transplant experiment revealed that the majority of the below-dam fish adopted a resident strategy, as well as above-dam fish, when both had experienced the above-dam environment. We conclude that high growth as a result of low density promotes residency in the above-dam sections.

Arch dam abutment stability analysis of arch dam design, construction, is the primary problem of operation. From home, outside the related data that appear most, arch dam accident due to abutment instability caused by. On the engineering geological condition is suitable, the arch dam is safe and reliable, economic and reasonable and the broad masses of the people welcomed the dam type. But it must be based on abutment stability based on. Therefore in the arch dam design, there is a need for dam abutment rock mass are detailed and thorough exploration and stability analysis of. This paper adopts the rigid body limit equilibrium method based on arch dam on the left bank of the slide stability analysis and dam abutment stability analysis of arch dam plane, gives the dam safety stability evaluation. A cover of hyperbolic arch dam, the dam height is 163.00m, is a type of buildings. The engineering geological conditions in the dam area is more complex, the existence of multiple faults, joints, fissures, karst cave is developed. Study of a dam on the left abutment stability, reliability and stability of project evaluation is a very important technical and economic significance.

DNA adenine methyltransferase (Dam) plays an important role in physiological processes of Gram-negative bacteria such as mismatch repair and replication. In addition, Dam regulates the expression of virulence genes in various species. The authors cloned the dam gene of Yersinia enterocolitica and showed that Dam is essential for viability. Dam overproduction in Y. enterocolitica resulted in an increased frequency of spontaneous mutation and decreased resistance to 2-aminopurine; however, these effects were only marginal compared to the effect of overproduction of Escherichia coli-derived Dam in Y. enterocolitica, implying different roles or activities of Dam in mismatch repair of the two species. These differences in Dam function are not the cause for the essentiality of Dam in Y. enterocolitica, as Dam of E. coli can complement a dam defect in Y. enterocolitica. Instead, Dam seems to interfere with expression of essential genes. Furthermore, Dam mediates virulence of Y. enterocolitica. Dam overproduction results in increased tissue culture invasion of Y. enterocolitica, while the expression of specifically in vivo-expressed genes is not altered.

In this article, we model the dependence between dam factor and D max, where dam factor is an indicator of risk of a tailings dam failure, which involves the height H of the tailings dam, the volume of material housed by the tailings dam VT and the volume dispensed by the tailings dam, VF, when the dam breaks. And, Dmax is the maximum distance traveled by the material released by the tailings dam, after the collapse. With the dependence found via copula models and Bayesian estimation, given a range of dam factor, we estimate the probability of the released material to exceed a certain threshold. Since the dam factor involves the released volume VF (unknown before the dam break), we present a naive way to estimate it using VT and H. In this way, it is possible to estimate the dam factor of a tailings dam and with such a value to identify the probability of the tailings dam to show a Dmax that exceeds a certain threshold.

This paper deals with engineering geological properties of Qadis Khordak dam site in Northwest Afghanistan. This study is based on on-site and laboratory tests, surface discontinuity surveying, drilled borehole and permeability test of dam foundation. The engineering geological properties at the dam site were studied in order to evaluate geotechnical characteristics of rock masses at dam foundation, geotechnical properties of alluvium at dam axis, reservoir and borrow materials. The structural geological studies also carried out due to stability and safety of dam on their abutments reservoir and seismicity. Existence of a fault, high permeable zone at dam foundation and the thickness of alluvium at dam axis, are the most engineering geological issues that cause change on dam type selection. In the feasibility phase, the dam type was chosen as the concrete face rock-fill dam, because of state of engineering geological properties of dam site. However, in the design phase dam type has been changed as a rock-fill with a clay core.

Abstract Every Dam must have an emergency plan document in which there is a dam collapse analysis. Based on previous research, it is stated that dam collapse often occurs due to runoff and piping. In this case, the Dam that will be studied is Salomekko Dam, located in Bone Regency. Salomekko Dam is located in the Salomekko Hamlet of Ulu Balang Village, Salomekko Subdistrict, Bone Regency, South Sulawesi Province, which provides water for agricultural irrigation. Analysis of the collapse of the Salomekko Dam was carried out due to overtopping and piping. The stillness of the air overflows through the top of the Dam. At the same time, the piping is caused by seepage in the dam body, which carries the dam material gradually. Analysis of the Salomekko Dam collapse using the Zhong Xing HY21 application can produce maps of flood inundation distribution, flood outflow hydrographs, and flood times. Based on these results, it can also have a hazardous impact to define boundaries of disaster-affected areas.
