The Value of Water in the Manufacture Industry and its Implications for Water Demand Policies. The Case of Chile
Authors: Tobarra-González Miguel Ángel
Published: November 2019

This paper studies the use of water in the manufacture industry of Chile using cross section data of 2,339 firms. A translog production function has been estimated in order to obtain important indicators as marginal productivity water value and demand price elasticity. A marginal value for water of 1,508.6 pesos per m3 (1.99 euros, 2.64 USD) has been obtained for the whole manufacture industry although there are important differences between sectors. Industrial water demand is elastic since price elasticity calculated is 1.1. This indicates that tariff policy can be a proper instrument to get water savings in the manufacture industry of Chile.

Published: November 2019

Nuestro estudio consiste en realizar una comparativa de 3.084 hoteles de diferentes ciudades de dos países (España y Francia) e identificar cuáles son los factores determinantes que más influyen en la fijación del precio del hotel de cada país analizando sus semejanzas y diferencias. Empleamos modelos hedónicos de precios basados en estimación por mínimos cuadrados (MCO) y en estimación por regresión cuantílica. Los resultados obtenidos tanto por MCO como por regresión cuantílica confirman que la categoría de hotel es una señal de calidad más fuerte en Francia que en España mientras que el eWOM tiene más influencia en el precio de habitación en España que en Francia. En ambos países el efecto de la concentración hotelera es positivo sin evidencia de diferencias significativas en ambos países.

Sniff Olfactometry: Temporal effects on odorant mixture perception in humans
Authors: Ding Kaifeng , Wang Xiaoyuan , Rinberg Dmitry , Acree Terry
Published: November 2019

There is evidence in mice and honeybees that signals initiated by odorants at the olfactory epithelium arrive downstream in the olfactory bulb between 10 and 200ms later and that these latencies are ligand dependent. It has recently been proposed that these latencies could be used by mice to identify or classify. Here we demonstrate that humans are sensitive to the timing of individual of odorant presentation. Using a two-alternate forced choice (2AFC) paradigm—subjects chose which odorant they recognized first after they experienced two 70ms puffs separated in time by some interval in the range of -450ms to +450ms. All subject recognition probabilities yielded the same linear function of latency (p<0.05) even though they differed in their recognition thresholds for the components and their recognition probability to detect them in binary mixtures. These results indicate that temporal structure of odor delivery affects human odor perception and sniff olfactometry (SO) has the temporal resolution necessary to measure these effects.
Overcoming Limitations in Dual Photoredox/Nickel catalyzed C–N Cross-Couplings due to Catalyst Deactivation
Authors: Gisbertz Sebastian , Reischauer Susanne , Pieber Bartholomäus
Published: November 2019

Dual photoreodox/nickel catalyzed C–N cross-couplings are an attractive alternative to the palladium catalyzed Buchwald-Hartwig reaction, but are limited to aryl halides containing electron-withdrawing groups. We show that the formation of catalytically inactive nickel-black is responsible for this limitation. Deposition of nickel-black further deactivates heterogeneous photocatalysts restricting their recyclability. We demonstrate that catalyst deactivation can be avoided by the combination of nickel catalysis and a carbon nitride semiconductor. The broad absorption range of the organic, heterogeneous photocatalyst enables a wavelength dependent reactivity control to prevent nickel-black formation. A second approach is to run the reactions at high concentrations to increase the formation of nickel-amine complexes that reduce nickel-black formation. This allows reproducible, selective C–N cross-couplings of electron-rich aryl bromides.
Extension of Frozen Natural Orbital Approximation to Open-Shell References: Theory, Implementation, and Application to Single-Molecule Magnets
Authors: Pokhilko Pavel , Izmodenov Daniil , Krylov Anna I.
Published: November 2019

Natural orbitals are often used in quantum chemistry to achieve a more compact representation of correlated wave-functions. Using natural orbitals computed as eigenstates of the virtual-virtual block of the state density matrix instead of the canonical Hartree-Fock molecular orbitals results in smaller errors when the same fraction of virtual orbitals is frozen. This strategy, termed frozen natural orbitals (FNO) approach, has been successfully used to reduce the cost of state-specific coupled-cluster (CC) calculations, such as ground-state CC, as well as some multi-state methods, i.e., EOM-IP-CC (equation-of-motion CC method for ionization potentials). This contribution extends the FNO approach to the EOM-SF-CC ansatz (EOM-CC with spin-flip), which has been developed to describe certain multi-configurational wave-functions within the single-reference framework. In contrast to EOM-IP-CCSD, which describes open-shell target states by using a closed-shell reference, EOM-SF-CCSD relies on high-spin open-shell references (triplets, quartets, etc). Consequently, straightforward application of FNOs computed for an open-shell reference leads to an erratic behavior of the EOM-SF-CC energies and properties, which can be attributed to an inconsistent truncation of the α and β orbital spaces. A general solution to problems arising in the EOM-CC calculations utilizing open-shell references, termed OSFNO (open-shell FNO), is proposed. The OSFNO algo-rithm first identifies corresponding orbitals by means of singular value decomposition (SVD) of the overlap matrix of the α and β molecular orbitals and determines virtual orbitals corresponding to the singly occupied space. This is followed by SVD of the singlet part of the state density matrix in the remaining virtual orbital subspace. The so-computed FNOs preserve the spin purity of the open-shell orbital subspace to the extent allowed by the original reference thus facilitating a safe truncation of the virtual space. The performance of the OSFNO approximation in combination with different choices of reference orbitals is benchmarked for a set of diradicals and triradicals. For a set of di-copper single-molecule magnets, a conservative truncation criterion corresponding to a two-fold reduction of the virtual space in a triple-zeta basis leads to errors of 5–18 cm-1 in the singlet–triplet gaps and errors of ∼2-3 cm-1 in the spin–orbit coupling constants.

Discovery of a Small Molecule Probe to Rpn-6, an Essential Subunit of the 26S Proteasome
Authors: Tian Wenzhi , Trader Darci
Published: November 2019

Rpn-6 is among several essential proteins that facilitate assembly of the 26S proteasome. We were interested in discovering a small molecule binder to Rpn-6 that could be used to further our understanding of the association of the 19S regulatory particle with the 20S core particle and if a small molecule-Rpn-6 interaction could potentially be cytotoxic to cancer cells that heavily rely on proteasome activity for survival. A workflow to utilize a one-bead-one-compound library and a thermal shift assay was developed to discover such a molecule. TXS-8 was discovered to have low micromolar range binding affinity for Rpn-6 and showed with very limited binding to other proteins. Cytotoxicity of TXS-8 was evaluated in several cell lines, revealing increased cytotoxicity to hematological cancers.
Computational Approach Choice in Modeling Flexible Enzyme Active Sites
Authors: Dokainish Hisham , Gauld James
Published: November 2019

The last step in the reductase step of the catalytic mechanism of MsrB was re-investigated using several computational approaches. Our previous QM-cluster paper showed that two possible mechanisms could occur, however the direct formation of disulfide from sulfonium cation was favored over sulfenic acid formation. In contrary, experimental studies suggest sulfenic acid formation. Therefore, first, we investigated the effect of level of theory, which confirmed previous conclusion. In addition, the effect of model choice was also investigated using ONIOM including a large QM layer around Cys440. Interestingly, deprotonating Cys440 leads to direct nucleophilic attack on Cys495 forming disulfide. Second, to eliminate the possibility that all previous results are an artifact of the used crystal structure in which the S...S distance is 3.29 Å, we ran a 5 ns MD simulation on the sulfonium cation intermediate. Surprisingly, our results show that the distance between the two sulfur is significantly increased to 4.88 Å. More importantly a water molecule is located in a proper position for nucleophilic attack. QM/MM calculations shows that sulfenic acid is formed via low barrier of 16.7 kJ mol-1. Finally, the effect of substrate binding on the two Cys's distance were investigated via running several MD simulations of possible intermediates, showing that substrate binding induces conformational changes increasing the sulfur's distance which is decreased upon substrate removal upon sulfenic acid formation. These results question the applicability of QM cluster approach in systems including flexible turns. It also emphasizes the importance of proper preparation of the starting structure.

Authors: Hala M Alkhalidi  , Khaled M Hosny
Published: November 2019

Aloe is a genus containing over 500 species of flowering plants. The most widely known species is Aloe Vera [AV], which mainly used internally and externally on humans as alternative medicine. The commercial topical dosage form has some limitations as absorption variability, short retention time, and improper viscosity and consistency.  This research aimed to reformulate AV as a topical hydrogel, to assess the rheological properties of this formulation, and to study the effect of storage on its rheological properties. AV hydrogel different formulation was prepared by using 0.5, 1, and 2% Carbopol 934 as a gelling agent in different concentrations. The rheological properties as viscosity, Farrow's constant, and rheological behaviors were determined. The effect of storage for twelve-month on the rheological properties was also performed. The results indicate that direct and non-linear relation between the concentration of carbopol 934 and the estimated viscosity of the hydrogel. The viscosity ranged from 9073 -936451 cp, which is suitable for topical application, the Farrow's constant was > 1; which confirmed the pseudoplastic flow with a thixotropic behavioral rheology. The effect of storage of formulation for 12 months has no significant effect on all rheological parameters at p ≤ 0.5, which indicated the stability of the prepared hydrogel. AV successfully prepared as a topical hydrogel; this formula will help in the elimination of improper consistency associated with topical marketed products. The rheological assessment indicated the suitability of the prepared formulation for topical application, the excellent stability in flow properties against storage for a prolonged period, and the formulation exhibited pseudoplastic flow with thixotropic behavioral rheology.

The use of RNA-sequencing technologies held a promise of improved diagnostic tools based on comprehensive transcript sets. However, mining human transcriptome data for disease biomarkers in clinical specimens are restricted by the limited power of conventional reference-based protocols relying on unique and annotated transcripts. Here, we implemented a blind reference-free computational protocol, DE-kupl, to infer yet unreferenced RNA variations from total stranded RNA-sequencing datasets of tissue origin. As a bench test, this protocol was powered for detection of RNA subsequences embedded into putative long noncoding (lnc)RNAs expressed in prostate cancer. Through filtering of 1,179 candidates, we defined 21 lncRNAs that were further validated by NanoString for robust tumor-specific expression in 144 tissue specimens. Predictive modeling yielded a restricted probe panel enabling more than 90% of true-positive detections of cancer in an independent The Cancer Genome Atlas cohort. Remarkably, this clinical signature made of only nine unannotated lncRNAs largely outperformed PCA3, the only used prostate cancer lncRNA biomarker, in detection of high-risk tumors. This modular workflow is highly sensitive and can be applied to any pathology or clinical application.

Uma das vegetações que tem sido utilizada pelas populações tradicionais ao longo do tempo, e investigada por especialistas é a do semiárido. Muitos estudos realizados nessa região são direcionados para espécies de usos madeireiro e medicinal. Nesta pesquisa, realizou-se uma análise pontual da distribuição local de Myracrodruon urundeuva Allemão, com base em informações coletadas em comunidades rurais de seis municípios do estado da Paraíba. Foram registrados 1.559 indivíduos de M. urundeuva em 144 horas de turnê guiada. Percebeu-se que que as populações desta espécie tendem a formar aglomerados, estando alguns localizados próximos as residências, o que pode ser explicado pela utilização medicinal das cascas para diversas enfermidades. Os dados abordados neste estudo refletem as características ambientais de cada área estudada, indicando para cada região a melhor forma de manejo para as populações locais desta espécie.  A B S T R A C TThe objective of this study was to analyze the daily and seasonal variations of the components of the radiation balance -and photosynthetically active radiation for the Caatinga during a dry year in Pernambuco Semi-Arid. The experiment was conducted during the year 2012 in Petrolina, PE, located in the Brazilian semiarid region. To determine the components of the radiation balance we used a balance radiometer CNR1 model installed the 13.3 meters of surface. Additionally, we analyzed the interaction between vegetation and radiation using sensors to monitor the photosynthetically active radiation above and in different positions under the canopy of scrub. These data were used to calculate the fraction of intercepted photosynthetically active radiation (fRFAi) and absorbed (fRFAa). A wide seasonal variation of solar radiation and net radiation was observed that reached daily averages around 23 MJ m-2 d-1 and 15 MJ m-2 d-1, respectively. In this case, it was observed that the magnitude of the component values of the radiation balance was mainly affected due to the cloudiness and changes in vegetation which mainly affected the levels of emittance and reflection surface. With regard to fractions of intercepted and absorbed photosynthetic active radiation, it was observed that they had daily average values over the next years, which were equal to 0.69 and 0.64 in order. This data can be extremely useful for a better understanding of the interaction between the savanna and the atmosphere under natural climatic conditions.Keywords: radiation, net radiation, photosynthetically active radiation, Caatinga, dry.
Application of Case Based Reasoning for Student Recommendations Drop Out (Case Study: Adisutjipto College of Technology)
Authors: Agustian Harliyus
Published: November 2019

The data of non-active students is an obstacle in a university because it is counted as a student body, thus affecting the lecturer ratio. For that reason, in order to improve the lecturer ratio, a way is needed in addition to adding lecturers, but also by evaluating the data of students who are not active and active to be filtered back by looking at academic data that is known so that students can continue their studies or should be advised to resign or also drop out . To solve these problems a system model is needed that can recommend students as drop out students and can also provide other recommendations that can be used as evaluations. Case-based reasoning method is used to see new data matching with old data, where active student data to be evaluated will be matched with student data that has been dropped out or received a warning letter, so that it will be used as a new solution. Case-based reasoning methods can help in recommending students to drop out or get a warning letter.
Cultural Centrality and Information and Communication Technology among Canadian Youth
Authors: Thiessen Victor , Looker Dianne E
Published: November 2019

This paper examines the positions of First Nations, Inuit and Métis (FNIM) peoples and visible minorities as distances from the cultural “centre” of White European culture. It then assesses the relation of information and communication technology (ICT) to these locations among Canadian youth using three data sets: the 2001 Aboriginal Peoples Survey, the 2000 Youth in Transition Survey (older cohort) and its 2002 follow–up, and a 2004/2005 survey collected by the authors. Findings indicate that the idea of cultural centrality is useful in locating FNIM groups and visible minorities vis-à-vis the cultural centre and each other and highlighting the stratified heterogeneity of these groups. Access to, use of, and development of ICT skills tend to mirror the relative positions of these groups in terms of cultural centrality. Further, youth who retain close ties with traditional culture are less unlikely to develop facility with ICT.

Published: November 2019

This study aims to identify the institutions that play a role in the procurement of rice seeds, describe the role of each institution, and develop policy recommendations for institutional strengthening of rice seed. The research was conducted in Nagari Lubuk Pandan, District 2x11 Six Lingkung, Padang Pariaman District, West Sumatera Province. The respondents' farmers were deliberately determined by 35 people based on the guidance of Wali Nagari and community leaders. Data were analyzed descriptively and presented in table and diagram. The results showed that 1) Institutional of rice seed in Nagari Lubuk Pandan consist of formal and informal institution. The formal institutions are Gapoktan "Lubuk Pandan Sejahtera" and Saprodi Kiosk. Informal institutions are groups of other farmers who lend rice seeds. More than half of the farmers of the respondents obtained rice seed from other farmers, because it was more efficient, 2) Gapoktan "Lubuk Pandan Sejahtera", played a role in channeling seeds to its members if there is a seed assistance program from the government. Saprodi Kiosk provides high quality rice seeds at all times, but very few farmers can afford them, and 3) Farmers' structural weaknesses (low education and knowledge, narrow land, technological mastery and low group manageability), cause they are unable to integrate the provision of seed input with the farm, so that production tends to decrease. This condition needs to be improved through institutional strengthening and empowerment of farmers through concepts acceptable to farmers

The Village Government is an institution that functions to organize village administration towards good governance. This study aims to analyze the implementation of the policy on the duties and functions of the village head in administering the administration of the Peana village, Pipikoro district, Sigi regency, Central Sulawesi Province, with reference to the aspects of communication, resources, disposition and bureaucratic structure. This qualitative research is carried out in Peana Village which is geographically isolated with limited infrastructure. Data were obtained from informants which are village officials and the community. Data are collected through observation to observe the behaviour naturally, original and spontaneous within a certain period of time to obtain careful, in-depth and detailed data. The data also obtained from documents originating from books, government regulations in the Peana Village Office as well as interview with the village secretary, village staffs and community members. The results showed that socialization about the content, purpose, direction and target group had not been implemented. Human resources, infrastructure and budget resources were inadequate. Village government disposition in responding to policies is not maximized. Bureaucratic structure in policy implementation, was not guided by standard operating procedure (SOP). The conclusion is that the task and function of the village head in the village administration is not optimally implemented, because the village head has not optimally responded regarding the administration of village administration. For this reason, the researcher recommends that the village head should be more active in responding to his duties and functions with the provided assistance by the academics, so that preparation and planning can be carried out effectively and efficiently.
