Authors: Morón Carlos , Ferrández Daniel , Saiz Pablo , Pérez Álvaro
Published: December 2018

ResumenEn los últimos años, ha habido una gran controversia sobre cuál es la cantidad óptima que deben dormir los estudiantes para afrontar con éxito la jornada escolar. Así, por un lado, se ha realizado una revisión del marco teórico basado en las investigaciones y estudios de diferentes autores sobre qué es el sueño, cuáles son las características del sueño en la adolescencia y cómo afecta el sueño a la capacidad de aprendizaje en los adolescentes. Por otro lado, también se ha realizado un estudio sobre los hábitos de sueño a un grupo de adolescentes de entre 12 y 13 años de tres centros escolares de la Comunidad de Madrid, con una muestra de 420 estudiantes de 1º y 2º de E.S.O, comparando los resultados obtenidos con las investigaciones referenciadas en el marco teórico, para contrastar la validez de las mismas. Además, se han consultado los expedientes académicos de los alumnos, a fin de comprobar si la cantidad de horas de sueño es un factor decisivo a la hora de obtener mejores o peores calificaciones. En conclusión, los resultados muestran una relación entre las horas de sueño y el rendimiento académico, donde se aconseja dormir un mínimo de 7.5 horas en la etapa de primer ciclo de secundaria y deja entre ver que quizá sea necesario un reajuste de los horarios escolares debido a los hábitos de los estudiantes.AbstractIn recent years, there has been a great controversy over which is the optimum amount of sleep a student should get to face successfully a school day. Thus, on one side, there has been a review of a theoretical framework based on investigation and researches of different authors about what sleep is, which the characteristics of sleep in the adolescence are, and how sleep affects the capacity of learning in adolescences. On the other side, the research of sleep habits was carried out with a group of adolescences between 12 and 13 years old from tree educational centers of Madrid Community, with a sample of 420 students of the first and the second cycle of Compulsory Secondary Education, comparing obtained results with the researches referenced in the theoretical framework, in order to contrast the validity of these researches. Moreover, the school records of the students were consulted with an aim to check whether the amount of sleeping hours is a decisive factor to obtain better or worse scores. In conclusion, the results show a relation between sleeping hours and academic performance, recommending sleeping minimum 7.5 hours during the stage of the first cycle of secondary education and rising the possible necessity to readjust school timetable according to the habits of the students.
A Comparative Study of Hydroxyapatite Coating Produced with Plasma Electrolytic Oxidation and Hydrothermal Treatment on Titanium Alloys: Ti6Al4V and Ti6Al7Nb for Dental Implants
Authors: Nahum Elinor , Lugovskoy Svetlana
Published: December 2018

Ti and Ti alloys are materials usually used in contact with hard tissue for applications such as artificial joints and dental implants. Ti6Al4V is a very common alloy used for dental implants, owing to its good mechanical properties and corrosion resistance. Nevertheless, because of uncertainties regarding the toxicity of vanadium and its influence on the human body, other Ti alloys containing no vanadium and retaining suitable properties are used. In this work Ti6Al4V and Ti6Al7Nb were oxidized in a water solution of calcium acetate (Ca(CH3COO)2) and calcium glycerophosphate (Ca(PO4CH(CH2OH)2) by Plasma Electrolytic Oxidation (PEO) for 20 minutes and then were hydrothermally treated (HTT) in water (pH=7) and in potassium hydroxide (KOH) solution (pH=11) for 2 hours at 200°C in a pressurized reactor. The surface morphologies, elemental composition and phase components were characterized by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and X-Ray Diffraction (XRD), respectively. The surface roughness was measured by Atomic Force Microscope (AFM) and thickness measurements were made by SEM and thickness gauge. Also, corrosion tests were made to evaluate the corrosion behavior of the two alloys. The aim of this study is to compare two viable Ti alloys, Ti6Al4V and Ti6Al7Nb, and to attain on their surface hydroxyapatite (HA) coating improving the osseointegration, as it simulates a human bone.

State estimation of conceptual hydrological models using unscented Kalman filter
Authors: Jiang P. , Sun Y. , Bao W.
Published: December 2018

Unscented Kalman filter (UKF) has its origin in transforming the Gaussian random variables for nonlinear estimation and has received little attention in the context of state estimation of conceptual hydrological models. This paper introduces UKF to estimate state variables of a conceptual hydrologic model. A symmetric point approach and a scaling framework are used for performing the sample generation process of UKF. This paper investigates the application of UKF for state estimation with a synthetic case study in which both the simulated state, the true state, and the corrected state are precisely known. The results show that the use of UKF can improve the performance of both the model outputs and the state variables as the difference between the corrected trajectories and the true trajectories decreases rapidly and tends to vanish after only a few iterations. Our results and comparisons also demonstrated the capability and usefulness of UKF for state estimation in two real basins.

Published: December 2018

The importance of water in everyday life is clear for humans and living creatures. In addition to supplying the water required for the body, it also contains necessary minerals. An increase or decrease in these minerals is responsible for various diseases and problems. Due to the growing consumption of treated water in Birjand, Iran and the need for the continuous monitoring of the quality of treated water, this descriptive research aimed to determine the chemical and microbiological quality of treated water of desalination stations in Birjand from September 23rd, 2015 to March 19th, 2016 (autumn and winter). Samples were directly taken from the desalination stations of Birjand. Physical and chemical tests were performed according to the Standard Methods. The results were compared with national standards as well as World Health Organization (WHO) guidelines. The results showed that almost all measured chemical and bacterial characteristics were less than the national and international standards. Also, the samples were standard in terms of coliforms and fecal coliforms. In some stations the concentrations of free residual chlorine and also magnesium were higher than standards. Therefore, periodic investigation of quality parameters is recommended in all desalination stations to reflect the results to authorities.

Authors: Molaei Oweis , Kouchakzadeh Mahdi , Fashi Fereshte Haghighi
Published: December 2018

In this study, the performance of rainwater harvesting (RWH) was assessed in terms of potential applicability for rainwater saving and non-potable water supply. Rainwater collecting from roofs of buildings was simulated in two cities with cold and semi-arid climate, namely Qazvin and Sanandaj. Rainfall statistics, information on the storage tank size, building roof areas and water demand (non-potable) were obtained. Buildings with roof areas of 100 m2 to 300 m2 were considered for the present study. It can be concluded that for cities located in cold and semi-arid climates, at least 60% of non-potable water can be supplied from roofs with a large area, a minimum 16% and maximum 70% for a low roof area, a minimum 8% and maximum 44% of the days per year from harvested rainwater. It is also found that for cities located in cold and semi-arid climates, it is possible to achieve at least 70% of non-potable water from large surface roofs. For the studied cities, with increasing tank size (1,000 to 5,000 L) rainwater saving was tangible for the same roof areas.

Published: December 2018

Bromate is mainly produced by ozone oxidation, and it is a kind of highly toxic substance in drinking water and a serious threat to people's health. It is difficult to remove it using traditional processes. The reduction of nano zero-valent iron (nZVI) has proved to be an effective method to remove bromate in water. In this study, we designed and prepared a new kind of nanocomposite by loading nZVI into ordered mesoporous silica materials (nZVI/MCM-41), which avoided nZVI oxide and increased adsorption at the same time. The removal efficiencies of bromate by MCM-41, nZVI, and nZVI/MCM-41 were evaluated respectively. The result indicated that nZVI/MCM-41 showed the highest removal efficiency for bromate at pH 6.5, with an appropriate dose of 25 mg when initial bromate concentration was 0.2 mg/L. In the removal process, adsorption and reduction exist at the same time and reduction was the leading role. Kinetic studies showed that the removal of bromate by nZVI/MCM-41 followed pseudo-ﬁrst-order kinetics. Finally, bromine mass balance demonstrated that bromide was the only product for bromate reduction, suggesting that bromate was ﬁrst adsorbed onto nZVI/MCM-41 and reduced to innocuous bromide by nZVI subsequently.

Authors: Elinoff Jason M. , Solomon Michael A.
Published: December 2018

The keynote address of the 2018 Pulmonary Hypertension Association (PHA) Scientific Sessions given by Dr Roham Zamanian, “From Clinical Classification to Precision-Phenotyping: Envisioning Precision Medicine in Pulmonary Hypertension,” was the perfect prelude to the final session of the symposium. In this session the speakers tackled the timely question: “Omics and Wearables in Pulmonary Hypertension: Are We There Yet?” Dr Michael Snyder of Stanford University described how longitudinal, integrative personal omics profiling that incorporate whole genome sequencing, multidimensional omics measurements, and data from wearables can be applied to: 1) determine what it means to be healthy; 2) potentially predict transitions from health to disease prior to symptom development; and 3) better monitor and treat chronic disease. Dr Anna Hemnes of Vanderbilt University shared promising preliminary data from the ongoing multicenter, collaborative PVDOMICS initiative (Redefining Pulmonary Hypertension through Pulmonary Vascular Disease Phenomics), funded by the National Heart, Lung and Blood Institute (NHLBI) and PHA. Finally, Dr Raymond Benza of the Allegheny Health Network shared intriguing pilot data on the safety and utility of an implantable hemodynamic monitoring device, the CardioMEMS™ HF system, in patients with advanced pulmonary arterial hypertension (PAH).

Authors: Qu Huanhuan , Li Baixue , Yang Jingyi , Liang Huaiwen , Li Meixia , Ding Kan
Published: December 2018

Background:

Disaccharide core 1 (Galβ1-3GalNAc) is a common O-glycan structure in
nature. Biochemical studies have confirmed that the formation of the core 1 structure is an important
initial step in O-glycan biosynthesis and it is of great importance for human body.

Objective:

Our study will provide meaningful and useful sights for O-glycan synthesis and their bioassay.
And all the synthetic glycosides would be used as intermediate building blocks in the scheme
developed for oligosaccharide construction.

Methods:

In this article, we firstly used chemical procedures to prepare core 1 and its derivative,
and a novel disaccharide was efficiently synthesized. The structures of the synthesized compounds
were elucidated and confirmed by 1H NMR, 13C NMR and MS. Then we employed three human gut
symbionts belonging to Bacteroidetes, a predominantphyla in the distal gut, as models to study the
bioactivity of core 1 and its derivative on human gut microbiota.

Results:

According to our results, both core 1 and derivative could support the growth of B. fragilis,
especially the core 1 derivative, while failed to support the growth of B. thetaiotaomicron and B.
ovatus.

Conclusion:

This suggested that the B. fragilis might have the specificity glycohydrolase to cut the
glycosidic bond for acquiring monosaccharide.

Authors: Song Ailing , Wang Lixin , Yang Wang , Li Yao , Cao Lei , Qin Xiujuan
Published: December 2018

Background:

Non-precious metal based catalysts have become a hot research material
due to their easy availability, low cost and outstanding electrochemical performance. Among them,
carbon-based materials like carbon nanotubes and porous carbon with their own characteristics are
especially favored by researchers in the field of catalyzing oxygen reduction. Therefore, rational
construction of combining porous carbon with carbon nanotubes attracts great research attention on
the object to utilize the excellent porosity, large specific surface area of porous carbon and the good
electronic conductivity, high stability of carbon nanotubes to catalyze oxygen reduction. In this
work, we synthesized two catalysts with different structure of coating carbon nanotubes with porous
carbon by paralyzing a mixture of pre-prepared porous carbon, Co3O4 nanoparticles and melamine/
glucosamine hydrochloride. Then, the composites were applied to fuel cells as cathodic oxygen
reduction reaction catalysts, which both exhibited good onset potential and excellent stability.

Objective:

Briefly, the porous carbon was prepared by heating the mixture of glucosamine hydrochloride
and Co(NO3)26H2O under N2 flowing. Co3O4 nanoparticles were prepared by pyrolyzing cobalt
nitrate-impregnated cotton wool. The CNTs/PC was synthesized by pyrolyzing the mixture of porous
carbon, Co3O4 nanoparticles and melamine. The CNTs@PC was synthesized by pyrolyzing the mixture
of porous carbon, Co3O4 nanoparticles and glucosamine hydrochloride. The cyclic voltammetry,
liner sweep voltammetry and chronoamperometry measurements were analyzed to obtained the catalysis
performance for oxygen reduction.

Results:

Through the rational design of catalyst structure, porous carbon and carbon nanotubes with
different structures were constructed to expose more active sites on the surface of the sample. As a
result, the onset potential of CNTs/PC and CNTs@PC are all at 0.9 V. After 20,000s chronoamperometry
measurement, the current holding rate of CNTs/PC reached 95%, CNTs@PC was 94%,
while Pt/C was only 77%. This shows that the prepared catalysts possess outstanding stability compared
to Pt/C.

Conclusion:

In this work, we synthesized two catalysts with different structure by paralyzing a mixture
of pre-prepared porous carbon, Co3O4 nanoparticles and melamine/glucosamine hydrochloride,
growing carbon nanotubes on the surface (CNTs/PC) and inside (CNTs@PC) of the porous carbon
framework. The catalytic property of prepared CNTs/PC and CNTs@PC all possess good onset potential
and excellent stability toward ORR. Therefore, a reasonable design of the catalyst structure is
required to expose more active sites on the sample surface.
A New Model of Identifying Differentially Expressed Genes via Weighted Network Analysis Based on Dimensionality Reduction Method
Authors: Hou Mi-Xiao , Liu Jin-Xing , Gao Ying-Lian , Shang Junliang , Wu Sha-Sha , Yuan Sha-Sha
Published: December 2018

Background:

As a method to identify Differentially Expressed Genes (DEGs), Non-
Negative Matrix Factorization (NMF) has been widely praised in bioinformatics. Although NMF
can make DEGs to be easily identified, it cannot provide more associated information for these
DEGs.

Objective:

The methods of network analysis can be used to analyze the correlation of genes, but
they caused more data redundancy and great complexity in gene association analysis of high dimensions.
Dimensionality reduction is worth considering in this condition.

Methods:

In this paper, we provide a new framework by combining the merits of two: NMF is applied
to select DEGs for dimensionality reduction, and then Weighted Gene Co-Expression Network
Analysis (WGCNA) is introduced to cluster on DEGs into similar function modules. The
combination of NMF and WGCNA as a novel model accomplishes the analysis of DEGs for cholangiocarcinoma
(CHOL).

Results:

Some hub genes from DEGs are highlighted in the co-expression network. Candidate
pathways and genes are also discovered in the most relevant module of CHOL.

Conclusion:

The experiments indicate that our framework is effective and the works also provide
some useful clues to the reaches of CHOL.
School Social Context, Students’ Self-Efficacy and Satisfaction in High School
Authors: Pedditzi Maria Luisa , Marcello Passarelli
Published: December 2018

Background:

Several studies have focused on the relationship between context variables and self-efficacy. Among the social variables, limited attention has been given to social capital and teacher-student relationship in the school community.

Objective:

This study aims to explore how social capital in the school community and teacher-student relationship may influence students’ self-efficacy and school satisfaction. Furthermore, is it suggested that these relations change according to school grade or transition point,i.e. first and final year of high school, and in relation to the student’s gender.

Methods:

A total of number of 2,623 high school students in their first and final years filled in questionnaires in Italy. We used Structural Equation Modelling (SEM) to test an ad hoc model that aimed to assess how the school context variables considered may influence students’ self-efficacy beliefs and school satisfaction.

Results:

Four different models were developed to categorise four different school grade sub-groups,i.e. first and final year students, and gender, i.e. boys and girls. The analyses of the results within the sub-samples reveal that social capital and teacher-student relationships influence students’ self-efficacy and school satisfaction differently.

Conclusion:

The results remarked the importance of differentiating guidance counselling for students in relation to specific transition and gender. Further implications for relevant educational practice are discussed at the end of this article.

DEP microelectrode and the protein concentration was quantified based on a biochemical interaction
using an Enzyme-Linked Immunosolvent Assay (ELISA). The protein distribution has been analysed
based on the β2M concentration for each microfluidic outlet.

Results:

At 300 kHz, the protein experienced a negative DEP (nDEP) with of 83.3% protein distribution
on the middle microchannel. In contrast, the protein experienced a positive DEP (pDEP) at 1.2
MHz with of 78.7% of protein on the left and right sides of the microchannel.

Conclusion:

This is concept proved that the tapered DEP microelectrode is capable of manipulating
a β2M via particle polarisation, hence making it suitable to be utilised for purifying proteins in biomedical
application.

Placental Thickness and Its Correlation with Gestational Age: A Cross-sectional Ultrasonographic Study
Authors: Acharya Sumnima , Tiwari Awadesh , Sharma Rupesh
Published: December 2018

Introduction: Placenta grows in size with the advancement of gestational age (GA) and plays an important role for delivery of nutrients from mother to fetus. Ultrasonography (USG) is implicated for the estimation of GA by using fetal growth parameters like Femur Length (FL), Bi-parietal Diameter (BPD), Head Circumference (HC), and Abdominal Circumference (AC). This study intends to observe the correlation between Placental Thickness (PT) and GA. Methods: It was an observational, cross-sectional, and analytical study conducted over a period of six months from November 2017 to April 2018. Fetal growth parameters i.e. FL, BPD, HC, and AC were measured to estimate GA. PT was also measured at the same time. Results: There was a positive correlation between PT and GA (r = 0.89, n=249, p < 0.001). Pearson correlation coefficient between the two variables at second and third trimesters were 0.81 and 0.49 respectively. Fisher r-to-z transformation was used to analyze the difference between those two coefficients and was found to be statistically significant (z = 4.6, p < 0.001). This indicates that there was a significant overall relationship between PT and GA. As GA increases, PT also increases. Conclusion: Our study observed a positive correlation between the PT and GA in second and third trimesters. Thickness of placenta can thus be used as a reliable parameter for the estimation of GA during the second and third trimesters, and can be used as a supplementary USG parameter along with FL, BPD, HC and AC.

RESEARCH DESIGN AND METHODS

Cognitive and brain imaging data were analyzed from 144 children with type 1 diabetes, ages 4 to <10 years, who participated in an observational study of the Diabetes Research in Children Network (DirecNet). Participants were grouped according to history of DKA severity (none/mild or moderate/severe). Each participant had unsedated MRI scans and cognitive testing at baseline and 18 months.

RESULTS

In 48 of 51 subjects, the DKA event occurred at the time of onset, at an average of 2.9 years before study entry. The moderate/severe DKA group gained more total and regional white and gray matter volume over the observed 18 months compared with the none/mild group. When matched by age at time of enrollment and average HbA1c during the 18-month interval, participants who had a history of moderate/severe DKA compared with none/mild DKA were observed to have significantly lower Full Scale Intelligence Quotient scores and cognitive performance on the Detectability and Commission subtests of the Conners’ Continuous Performance Test II and the Dot Locations subtest of the Children’s Memory Scale.

CONCLUSIONS

A single episode of moderate/severe DKA in young children at diagnosis is associated with lower cognitive scores and altered brain growth. Further studies are needed to assess whether earlier diagnosis of type 1 diabetes and prevention of DKA may reduce the long-term effect of ketoacidosis on the developing brain.

Is it Necessary: Quality Control in Cataloging?
Authors: Nero Muriel D. , He Jia
Published: December 2018

Catalogers and technical services departments have always struggled with how much is too much when creating and enhancing bibliographic records as well as with what physical processing is needed to make these materials shelf-ready for timely circulation.  Along with these decisions, catalogers also must address what quality control measures, if any, should be in place to guarantee resources are discoverable in the OPAC and discovery service. The authors of this paper describe their process and workflow for the quality control of tangible and electronic resources; they also discuss why quality control is performed. The importance of training cataloging staff on current cataloging rules and practices as a preventive measure to reduce mistakes is an essential part of the process.  The ultimate goal of quality control is to eliminate errors and ensure the library’s resources are accessible.
‘Cos I’m a Survivor’

Published: December 2018

In post-war Finland thousands of children experienced poor upbringing, neglect and abuse, and had to deal with their experiences without social support from adults. In this article we study how difficult and bitter experiences related to childhood crises are remembered, reinterpreted and reframed in later life and in contemporary Finland. As research material we use both oral and written reminiscences of childhood in the post-war years collected in the period 2014–2016. We argue that in the recollections of difficult childhood coping and resilience emerge as major narrative themes. Although informants in their childhood were forced to suffer in silence, they remember themselves as being resilient and capable of surviving in adverse environments. In their late adulthood public collection of childhood memories has offered them a suitable medium to remember and reframe their experiences as meaningful, by exposing the ‘culture of silence’ which prevailed in the post-war Finland.

Authors: Ferrin Bolaños Carlos Diego , Loaiza Correa Humberto
Published: December 2018

El número de trabajos relacionados con Interfaces Cerebro-Computador (BCI, Brain-Computer Interface en inglés) directamente aplicados al proceso de rehabilitación de pacientes con lesiones de médula espinal está en aumento debido a la mejora en las técnicas de procesamiento digital de señales y reconocimiento de patrones que permiten relacionar las señales electroencefalográficas con acciones motoras. Los resultados preliminares de las pruebas de las BCI sobre sujetos reales permiten visualizar en un futuro relativamente cercano la inclusión de este tipo de herramientas en los protocolos de rehabilitación. Sin embargo, hay muchas barreras por resolver, principalmente las relacionadas con el aumento del desempeño y la generación de múltiples comandos naturales mediante interfaces cerebro-computador a partir de electroencefalografía superficial (EEG). En este trabajo se hace una revisión de los más importantes trabajos que muestran la evolución, el estado actual  y las oportunidades de investigación alrededor de la temática de interfaces cerebro-computador en procesos de neurorrehabilitación de miembros superiores en pacientes con lesiones medulares.

Published: December 2018

Профессиональная деятельность преподавателей сопряжена с воздействием большого числа стресс-факторов, которые могут проявляться на работе, во взаимоотношениях с начальством, напряженной обстановкой в коллективе, вследствие различных социально-психологических переживаний на работе и дома. Длительное воздействие этих факторов способствует развитию синдрома эмоционального выгорания, профилактика которого просто необходима. Целью исследования было выявить симптомы синдрома эмоционального выгорания у преподавателей гуманитарных высших учебных заведений и разработать мероприятия по его профилактике. Обследовано 1489 преподавателей гуманитарных вузов с помощью составленных анонимных анкет для изучения профессиональной деятельности педагогов, а также выборочных карт на основании листков нетрудоспособности. Для статистического анализа рассчитывали средние величины и их ошибки, интенсивные и экстенсивные показатели; использовали метод сравнения относительных величин и определение достоверности различия. Выявлено, что у двух преподавателей из трех присутствуют чувство усталости, частые боли в спине и груди, головная боль. В результате балльной оценки степени выраженности данных симптомов обнаружено, что большая часть преподавателей (43,2%) оказалась в группе с высоким уровнем психоэмоционального выгорания. У каждого второго преподавателя наблюдается низкий уровень медицинской активности. Для профилактики синдрома эмоционального выгорания необходимо внедрение мероприятий, направленных на формирование позитивной медицинской активности, повышение медицинской грамотности и воспитание навыков здорового образа жизни.

Objective: This study was aimed to determine possible relationship between the types of human constitution used in Mongolian traditional medicine and certain types of immune response in healthy blood donors. Materials and methods: Ninety-three blood donors were enrolled in this cross-sectional study. The type of human constitution was determined using the method of Sachs R (1995) and modifi ed by Batchimeg et al. (2003), in which the titer of cytokines (Human IL-2, IL-6, IL-10, IFNγ and TGFβ) in blood plasma and in supernatant of 12- hour PBMC culture were measured by ELISA. Results: Analysis and comparison of different cytokine titers in different constitution groups produced the following fi ndings: Subjects with Badgan ( Tibetan-badken, or phlegm, or bile) type of constitution had a lower activity of Th2 mediated immune response; subjects with Shar ( Tibetan-mkrispa [kris-pa] or mucus) humour domination had a higher activity of Th2 mediated response; and subjects with Khii humour domination may demonstrate higher activity of Th1 mediated response. Conclusion: Human typology types used in Mongolian traditional medicine are likely related to activity or intensity of certain types of adaptive immune responses and authors see an essential need to continue research in this fi eld of study.

The “Sanctuary” of Fortuna Salutaris and Jupiter Optimus Maximus at Ampelum (Zlatna/Zalatna, Alba County). Rethinking the Archaeological Evidence
Authors: MUSTAȚĂ Silvia
Published: December 2018

In 1900, with the occasion of construction works caused by the expansion of the foundry of Zlatna, a group of five Roman bronze vessels, positioned upside down in a pit, were discovered. In the proximity of the pit, two altars dedicated to Fortuna Salutaris and Jupiter Optimus Maximus were identified. This situation made Gábor Téglás presume that a sanctuary dedicated to the two divinities existed in this area during the Roman period and that the vessels were employed in different cultic activities undertaken here. The paper focuses on the character of the discovery and on the composition of the bronze vessels assemblage. It states that the context of the discovery does not allow with certainty a correlation between the two altars and the five bronze vessels. In the present state of research, the vessels of Ampelum represent the only confirmed example from Roman Dacia of a bronze drinking assemblage and the most direct evidence for the preparation of calda (wine mixed with warm water).
Rezumat: “Sanctuarul” Fortunei Salutaris şi al lui Iupiter Optimus Maximus de la Ampelum (Zlatna/Zalatna, judeţul Alba). Regîndirea documentaţiei arheologice. Cu ocazia lucrărilor de construcție efectuate în 1900 pentru extinderea topitoriei din Zlatna a fost identificată, printre altele, o groapă care a conținut cinci vase romane din bronz, așezate cu gura în jos. În apropierea gropii au fost descoperite două altare votive, dedicate Fortunei Salutaris și lui Iupiter Optimus Maximus. Situația arheologică l-a determinat pe Téglás Gábor să presupună că în zonă a existat un sanctuar dedicat celor două divinități și că vasele de bronz au fost folosite în cadrul activităților cultice desfășurate aici. Articolul analizează circumstanțele descoperirii și caracteristicile vaselor de bronz. Este susținut faptul că informațiile referitoare la contextul de descoperire nu sunt suficiente pentru a presupune o legătură directă între cele două altare și grupul de vase de bronz. De asemenea, în stadiul actual al cercetării, vasele de bronz descoperite la Ampelum reprezintă singurul serviciu din metal identificat până acum în Dacia romană, care a fost folosit, foarte probabil, pentru a prepara calda (vin amestecat cu apă caldă).
