Opis:
Paramagnetic centers in the two exemplary synthetic and natural dental biocompatible materials applied in implantology were examined by the use of an X-band (9.3 GHz) electron paramagnetic resonance (EPR) spectroscopy. The EPR spectra were measured in the range of microwave power 2.2–70 mW. The aims of this work were to compare paramagnetic centers concentrations in different dental biocompatible materials and to determine the effect of microwave power on parameters of their EPR spectra. It is the very fi rst and innovatory examination of paramagnetic centers in these materials. It was pointed out that paramagnetic centers existed in both natural (~1018 spin/g) and synthetic (~1019 spin/g) dental biocompatible materials, but the lower free radical concentration characterized the natural sample. Continuous microwave saturation of EPR spectra indicated that faster spin-lattice relaxation processes existed in synthetic dental biocompatible materials than in natural material. Linewidths (ΔBpp) of the EPR spectra of the natural dental material slightly increased for the higher microwave powers. Such effect was not observed for the synthetic material. The broad EPR lines (ΔBpp): 2.4 mT, 3.9 mT, were measured for the natural and synthetic dental materials, respectively. Probably strong dipolar interactions between paramagnetic centers in the studied samples may be responsible for their line broadening. EPR spectroscopy is the useful experimental method in the examination of paramagnetic centers in dental biocompatible materials.

Opis:
This paper addresses collective emotional intelligence as a construct that establishes a relationship among members of an organisational community and how this is a path for improving firms' performance. It is based on the premise that several factors influence the selected to solve a problem in any decision-making process. In addition to analysing the practical values that the information provides, it is also subject to the emotional responses that the decision-makers may have. These samples make up the emotional intelligence transferred from individuals and their organisational interactions to the organisation itself. This paper seeks to find the relationship between the variables of Collective Emotional Intelligence (CEI) with Subjective Well-Being (SWB) and Perceived Happiness (HP). To this end, a data collection instrument was applied to 384 workers in technology-based companies in northern Mexico. A descriptive, correlational, and multivariate analysis, including SEM study, was carried out to validate the hypotheses. The results validate the importance of SWB and HP in developing CEI and suggest specific actions on workers' perceptions. These actions meet expectations and requirements expressed by workers and aim to increase organizational intelligence and CEI to improve decisionmaking.
Niniejszy artykuł omawia zbiorową inteligencję emocjonalną jako konstrukt, który ustanawia relacje pomiędzy członkami społeczności organizacyjnej oraz wskazuje dlaczego jest to ścieżka do poprawy wyników firm. Opiera się na założeniu, że na wybór rozwiązania problemu w dowolnym procesie decyzyjnym wpływa kilka czynników. Poza analizą praktycznych wartości, których dostarczają informacje, podlegają one również reakcjom emocjonalnym, które mogą wystąpić u decydentów. . Próbki te składają się na inteligencję emocjonalną przeniesioną z jednostek i ich interakcji organizacyjnych na samą organizację. W niniejszej pracy podjęto próbę znalezienia związku między zmiennymi zbiorowej inteligencji emocjonalnej (CEI) z subiektywnym dobrostanem (SWB) i postrzeganym szczęściem (HP). W tym celu zastosowano narzędzie do gromadzenia danych w odniesieniu do 384 pracowników firm technologicznych w północnym Meksyku. W celu potwierdzenia hipotez przeprowadzono analizę opisową, korelacyjną i wielowymiarową , w tym badanie SEM. Wyniki potwierdzają znaczenie SWB i HP w rozwoju CEI i sugerują konkretne działania w zakresie postrzegania pracowników. Działania te spełniają oczekiwania i wymagania wyrażone przez pracowników i mają na celu zwiększenie inteligencji organizacyjnej i CEI w celu usprawnienia procesu decyzyjnego.

Opis:
Root-knot nematodes, genus Meloidogyne, are among the most plant damaging pathogens worldwide. The action of natural products against plant pathogens has been investigated to assess their effectiveness in the control of diseases. Thus, the present study aimed to evaluate the phytochemistry potential of the Ficus species for the control of Meloidogyne javanica. In vitro inhibitory activity assays were performed with crude ethanolic extracts of leaves and branches from 10 Ficus species. Among these, Ficus carica extracts exhibited strong paralysis activity against second stage juveniles (J2) (EC50 = 134.90 μg ∙ ml–1 ), after 72 hours. In addition, high efficacy was observed in egg-hatching inhibition at different embryonic stages. Microscopy analysis revealed severe morphological alterations in the nematode tissues at the J2 stage, as well as immotility of juveniles released from eggs in the presence of F. carica extracts. The efficacy of the treatments for the other species was very low. These differences were supported by the variation in the compound classes, mainly for alkaloids and metabolite profiles by Gas Chromatography/Mass Spectrometry (GC/MS) when F. carica was compared with the other species. The results indicated that F. carica is a promising source for the isolation and identification of molecules capable of acting in the control of M. javanica.

Opis:
Although tracks of dinosaurs are well known from Upper Jurassic sediments, tracks of non−dinosaurian vertebrates are fairly rare. The Upper Jurassic Lastres Formations of Asturias in northern Spain contain many vertebrate tracksites that include footprints and trackways of non−dinosaurian tetrapods. Several of these tracks are natural casts of pentadactyl to tridactyl footprints with digits connected by arched structures. The digits are short with deep scratch marks oriented anteriorly. The Asturian tracks show a high degree of morphological similarity to other specimens previously described as possible turtle tracks. Observations from extant turtle trackways show some surprising similarities with the fossil material. The tracks are here interpreted as having been made by turtles partially buoyed by water or by turtles walking in a slightly wet subaerial environment.

Opis:
Nitrate assimilation in the plant cell is mainly regulated by the enzyme nitrate reductase (EC 1.6.6.1), which catalyzes the nitrate to nitrite reduction. Nitrate reductase activity (NRA) is measured at the major nitrate reduction site, which can be the root or shoot, depending on the species. The in vivo assay has often been used for NRA measurement, and protocol also usually varies with the species. The goals of this study were: (1) to identify the major nitrate reduction site in seedlings of two tree species, Eucalyptus urophylla and Khaya senegalensis, and (2) to optimize the in vivo nitrate reductase assay at the major nitrate reduction site in these species. Healthy seedlings aged 180 and 160 days, respectively, were selected for NRA measurement in fully expanded leaves and main root. After identifying the main nitrate reduction site of each species, the effects of variations in temperature, nitrate concentration and pH in the incubation medium were assessed. The results showed that the leaf and the root are the major nitrate reduction site of Eucalyptus urophylla and Khaya senegalensis, respectively. The optimal conditions for the in vivo assay in the leaf were 35 °C, $KNO_3$ 100 mM, and pH 7.0, whereas for the root they were 30 °C, $KNO_3$ 100 mM, and pH 7.5.

Opis:
Different groups of free radicals exist in biological material like animal tissues or plants parts. The processes like heating or cooling creates additional types of free radicals groups in this organic matter, due to changes in chemical bonds. The paper proposes a method to determine types and concentrations of different groups of free radicals in the matter processed in various temperatures. The method extracts the spectrum of free radicals using electron paramagnetic resonance with the microwave power of 2.2 mW. Then an automatic method to find a best possible fit using limited number of theoretical mathematical functions is proposed. The match is found using spectrum filtration, and a genetic algorithm implementation supported by a Gradient Method. The obtained results were compared against the samples prepared by an expert. Finally, some remarks were given and new possibilities for future research were proposed.

The aim of the present review is to investigate the main field-based tests, used alone or included in sport or fitness batteries, for the assessment of health- and skill-related physical fitness components in adolescents. Different scientific databases were searched through using the selected key words related to physical fitness and its components for adolescence. The search focused on original articles and reviews/meta-analyses using valid, reproducible and feasible tests that fit within the school environment. A total of 100 scientific manuscripts were included in the qualitative synthesis. The present systematic review pointed out 5 fitness tests that well adapt to the evaluation of the components of physical fitness of adolescents within a school environment: the 20 m shuttle run test for cardio-respiratory endurance; the handgrip strength test for upper body maximal strength; the standing broad jump test for lower body maximal strength; the sit-up test to exhaustion for muscular endurance and the 4×10 m shuttle run test for speed, agility and coordination. These fitness tests have been finally selected and incorporated into the Adolescents and Surveillance System for the Obesity prevention – Fitness Test Battery (ASSO-FTB), and will be adopted within the ASSO Project for evaluation purposes. This instrument could be also provided to teachers and people working in schools in order to assess physical fitness of adolescents over time and prevent obesity and related diseases.

Opis:
Aim: This study aims to evaluate the technical efficiency of 44 Brazilian port terminals that handled containers in 2016. The evaluation will first proceed by identifying the main benchmarks. It will then provide an analysis of variables that may have an effect on technical efficiency as well as the nature of their relationship with the latter--namely: container movement and specialized terminals.   Design / Research methods: In this work we apply the techniques of Data Envelopment Analysis and Free Disposal Hull. Output-oriented models were constructed, using three inputs - berth depth, berth length and number of berths, and three outputs - number of containers handled, medium board measured in container handled per hour of mooring, and medium consignment rate measured in container throughput per ship.   Conclusions / findings: The main results show that half of the terminals have an inefficient infrastructure, with capacity larger than necessary to meet current demand for transportation of containers. In addition, there is a strong relationship between the efficiency and size of a terminal port and between the efficiency and degree of specialization. Moreover, the private use terminal of (TUP) Itacal and public quay OCRIM can serve as benchmarks for most of the terminals.   Originality / value of the article: Relatively few works in the literature tried to measure technical efficiency for developing countries. Besides that, none of the works found regarding Brazilian ports have shown the scenario after promulgation of the Port’s Law in 2013, and only a few used container cargo as focus. This article is of interest for scientists of the sector, exporters/importers, and Brazilian Government officers interested in observing the effects of public policies aimed at the sector. We also suggest future work concerning the sector's improvements which can follow from our findings.
