Zeolite Usage for Interventions in Accidental Polutions by Mine Waters in Maramureş County

This study presents the results obtained using natural zeolites for retaining heavy metals from the Maramureş rivers affected by the mining activities. Natural zeolites from the north-west Transylvania have been tested, i.e. zeolite from Călineşti-Maramureş and two sorts of zeolites manufactured by SC Zeolitos SRL Oradea. Natural zeolites represint a technical and economical alternative to ion-exchange synthetic resins and classical waste water technologies. Heavy-metal containing waters from Cisla, Burloaia, Cavnic, Săsar, Buşag and Ilba rivers have been used. Metal concentrations of untreated vs. treated samples have been determined for the zeolites containing clinoptilolite. The adsorbtion of metals (Mn, Cu, Zn) during a 24h period has been studied for various zeolites

CO21 234. Implantación trans apical de válvula aórtica: excelentes resultados en pacientes de alto riesgo

ObjetivosLa implantación transapical de válvulas aórticas es un método nuevo aplicable a pacientes de alto riesgo y estenosis grave de válvula aórtica. Un informe de nuestra experiencia inicial.MétodosDesde abril de 2008 fueron tratados 208 pacientes (edad 79±8 anos, media 36-99 años), con el método híbrido de implantación transapical de válvula aórtica. La media logística EuroSCORE (STS) fue de 40±20% (6-97%) y la media del STS score 21±16% (3-97%). Catorce pacientes ingresaron en shock cardiogénico. Operaciones combinadas fueron efectuadas en 30 pacientes. Intervención de coronarias con stent en 25 pacientes, corrección de ASD en un paciente, dilatación de estenosis pulmonar en un paciente. Aneurismectomía en dos pacientes.Implantación de stent en la arteria renal en un paciente.ResultadosEl éxito técnico de las operaciones fue del 99,5%, la mortalidad hospitalaria fue de 5,7% para todo el grupo, 21% para el grupo en shock cardiogénico. No hubo complicaciones neurológicas en ningún paciente. En el 6% de los pacientes operados hubo la necesidad de implantación de marcapasos. El análisis de regresión univariante demuestra que el shock cardiogénico, elevado B-type natriuretic peptide (BNP)-level, son claros indicadores para la mortalidad postoperatoria temprana (30 días después de la operación). Shock cardiogénico, New York Heart Association (NYHA) IV, altos scores de riesgo, insuficiencia renal grave, son factores independientes para la predicción de la mortalidad acumulativa.ConclusionesLa técnica de recambio transapical de válvulas aórticas reduce significativamente el riesgo operatorio en pacientes de alto riesgo en comparación con el método convencional de recambio valvular aórtico

Assessment of subacromial space and its relationship with scapular upward rotation in college baseball players.

CONTEXT: Subacromial impingement is a common injury in baseball players and has been linked to a reduction in the subacromial space. In addition, it has been suggested that decreases in scapular upward rotation will lead to decreases in the subacromial space and ultimately impingement syndrome. OBJECTIVE: The objective of this study was to evaluate the relationship between acromiohumeral distance and scapular upward rotation in healthy college baseball players. DESIGN: Posttest-only study design. SETTING: Controlled laboratory setting. PARTICIPANTS: 24 healthy college baseball players. Intervention: Participants were measured for all dependent variables at preseason. MAIN OUTCOME MEASURES: Acromiohumeral distance at rest and 90° of abduction was measured with a diagnostic ultrasound unit. Scapular upward rotation at rest and 90° of abduction was measured with a digital inclinometer. RESULTS: Dominant-arm acromiohumeral distance at rest and 90° of abduction (P = .694, P = .840) was not significantly different than in the nondominant arm. In addition, there was not a significant correlation between acromiohumeral distance and scapular upward rotation at rest and 90° of abduction for either the dominant or the nondominant arm. CONCLUSIONS: These results indicate that the acromiohumeral distance is not adapting in the dominant arm in healthy throwing athletes. In addition, a relationship was not identified between acromiohumeral distance and scapular upward rotation, which was previously suggested. These results may suggest that changes that are typically seen in an injured population may be occurring due to the injury and are not preexisting. In addition, scapular upward rotation may not be the only contributing factor to acromiohumeral distance

Photometric characterization of Lucideon and Avian Technologies color standards including application for calibration of the Mastcam-Z instrument on the Mars 2020 rover

Several commercially available color standards exist, generated by a variety of manufacturers including LabSphere, Lucideon, and Avian Technologies. Previous work has characterized the photometric properties of LabSphere Spectralon targets. Here, we measure the visible and shortwave infrared (VSWIR; 0.4 to 2.5  μm) reflectance at multiple angles and determine the photometric properties of materials manufactured by Lucideon and Avian Technologies for potential use as calibration target materials for the Mars 2020 Mastcam-Z instrument. The Lucideon black, gray 33, green, and cyan samples are found to be significantly forward scattering. The yellow, red, and gray 70 samples are found to be weakly forward scattering. The Avian Technologies AluWhite98 sample was found to be weakly backward scattering. We characterize the absorptions observable and note the occurrence of wavelength-dependent photometric properties. The reflectance and photometric data collected and released here enable the use of these color standards for calibration of data from Mastcam-Z and other Mars-2020 rover instruments as well as provide key information for many other imaging and spectroscopy applications that require the calibration of data from multiple lighting or viewing geometries

A modern network approach to revisiting the positive and negative affective schedule (PANAS) construct validity

Introduction: The factor structure of the Positive and Negative Affective Schedule (PANAS) is still a topic of debate. There are several reasons why using Exploratory Graph Analysis (EGA) for scale validation is advantageous and can help understand and resolve conflicting results in the factor analytic literature. Objective: The main objective of the present study was to advance the knowledge regarding the factor structure underlying the PANAS scores by utilizing the different functionalities of the EGA method. EGA was used to (1) estimate the dimensionality of the PANAS scores, (2) establish the stability of the dimensionality estimate and of the item assignments into the dimensions, and (3) assess the impact of potential redundancies across item pairs on the dimensionality and structure of the PANAS scores. Method: This assessment was carried out across two studies that included two large samples of participants. Results and Conclusion: In sum, the results are consistent with a two-factor oblique structure.Fil: Flores Kanter, Pablo Ezequiel. Universidad Empresarial Siglo XXI; Argentina.
