title: CHEMICAL STUDY OF SALTS EFFLORESCENCES OF THE ARCHAEOLOGICAL SITE TOCA EXÚ DO JURUBEBA OF THE NATIONAL PARK SERRA DA CAPIVARA, PIAUÍ, BRAZIL.

description: Toca Exú do Jurubeba is part of a set of archaeological sites located in the Serra da Capivara National Park (Piauí, Brazil), a region of great world interest due to its archaeological potential, especially rock art. However, rock art is constantly threatened by both natural and anthropic factors. Among the natural salts efflorescences that are deposited on the painted graphics often even concealing them. The present study consisted of the spectroscopic analysis of different saline efflorescence samples of the Serra da Capivara National Park, using examination techniques (optical microscopy and Scanning Electron Microscopy) and analysis (Fourier Transform Infrared and Laser Induced Breakdown Spectroscopy). The analysis allowed to identify at least four different compositions of the samples as a mixture of hydrated calcium oxalate (CaC2O4 H2O) with kaolinite (Al2SiO3(OH)4), gypsum (CaSO4 2H2O), tetrahydrate calcium nitrate (Ca(NO3)2 4H2O) and aluminosilicates in the state of fossilization. The obtained results open the way for the conservation of rock art, initially in the archaeological site under study and can serve as basis for other interventions that may be developed in the region.

title: PERFORMANCE OF A PALLADIUM FILM ELECTRODE FOR THE DETERMINATION OF THALLIUM AND LEAD IN NATURAL WATER SAMPLE BY DIFFERENTIAL PULSE ANODIC STRIPPING VOLTAMMETRY

description: The use of a palladium film electrode (PdFE) as an alternative electrode for the determination of thallium (Tl+) and lead (Pb2+) in water samples by anodic stripping voltammetry is proposed. Preliminary studies of the influence of the substrate were performed on the electrochemical behavior of PdFE prepared ex situ. Using a silver solid amalgam electrode as substrate (AgSAE), the effect of several parameters such as potential and deposition time, composition and pH of supporting electrolyte on the analytical response of PdFE for Tl+ by differential pulse anodic stripping voltammetry (DPASV) was initially investigated. Under best experimental conditions of deposition potential of −1.2 V and deposition time of 300s the analytical curve was linear in the Tl+ concentration from 3.0 to 100.0 µg L−1 with a relative standard deviation (RSD) &lt;2.0%. The limit of detection (LOD) and limit of quantification (LOQ) were 0.89 µg L−1 and 2.96 µg L−1, respectively. The PdFE was successfully applied for the determination of Tl+ in water samples. Moreover, this electrode showed promising as a sensor for the simultaneous determination of Tl+ and Pb2+ and as a suitable alternative to the mercury electrode.

title: Identification of a novel mutation in ARSA gene in three patients of an Iranian family with metachromatic leukodystrophy disorder

description: Abstract Metachromatic leukodystrophy disorder (MLD) is an autosomal recessive and lysosomal storage disease. The disease is caused by the deficiency of the enzyme arylsulfatase A (ARSA) which is encoded by the ARSA gene. Different mutations have been reported in different populations. The present study was aimed to detect the mutation type of the ARSA gene in three relative Iranian patients. We found a novel homozygous missense mutation c.1070 G &gt; T (p.Gly357Val) in exon 6 of these patients. The mutation was found to be reported for the first time in MLD patients. The data can update the mutation profile and contribute toward improved clinical management and counseling of MLD patients.

title: SYSTEMATIC LITERATURE REVIEW ON MODELS AND PRACTICES OF EARLY CHILDHOOD INTERVENTION IN BRAZIL

description: ABSTRACT Objective: To identify which Early Childhood Intervention practices and models are described in the Brazilian literature. Data sources: A systematic integrative review of the literature indexed in databases from Virtual Health Library, Bielefeld Academic Search Engine, Education Resources Information Center and Portal of Periodicals of the Coordination of Improvement of Higher Education Personnel was carried out, considering the period between 2005 and 2015. The following articles were analyzed: those published in English or Portuguese, fully available online, with the terms “Early Intervention”, “Early Stimulation” or “Essential Stimulation” in the title, abstract or keywords; studies that enrolled children aged from 0 to 6 years, their caregivers or professionals in Early Intervention services; manuscripts published in journals classified as ≥ B2 (WebQualis; Qualis 2014) in the fields of Education or Physical Education; and studies that described Early Intervention practices. Data synthesis: Early Intervention seems to be developed exclusively related to the health sector, with prevalence of practices aimed at stimulating skills through the use of clinical approaches, whose focus is centered on the child and structured in the model of rehabilitative care. Conclusions: The adoption of Early Intervention practices and models are far from those recommended and recognized by the international literature as good practices. In this sense, the need of continuous education of professionals involved in this area is shown, as well the need for investments in research on this subject.

title: The impact of the Bolsa Família Program on the duration of formal employment for low income individuals

description: Abstract This article uses microdata from the Unified Registry of Social Programs (CadUnico) and the Annual Social Information Report (Rais) to examine the duration of employment for families receiving benefits from the Bolsa Família Program. To achieve this goal, Cox proportional hazard models were used to estimate the job duration for beneficiaries and non-beneficiaries of the program using a database of more than three million people. The findings indicate that the risk of leaving work among beneficiaries of the Bolsa Família Program is 7% to 10% lower than the risk for non-beneficiaries. Parametric models were also adjusted to verify robustness, producing results equivalent to those of the Cox model. In all cases, participation in the program was observed through a covariate that varies over time, extracted directly from the program’s payment records.

title: A phytosociological analysis of the <i>Olea europaea</i> L. var. <i>sylvestris</i> (Mill.) Lehr. forests in Sicily

description: This paper presents a phytosociological study on the forest vegetation of <i>Olea europaea</i> var. <i>sylvestris</i> of Sicily and of the smaller minor islands. In Sicily, Oleaster formations show considerable climacic potentiality in the bioclimactic belts between the infra- and the thermomediterranean with single edapho-climacic penetrations that are also in the mesomediterranean; however, these were largely destroyed by man in order to make room for crops. Furthermore, the residual expressions of the Oleaster forests are limited, and often exist as regenerated woodland made possible by the abandonment of agricultural land; they are often small forest nuclei – high maquis, woods and micro-woods – with a more or less discontinuous distribution within the agricultural landscape. The fieldwork is supported by 120 phytosociological surveys carried out in various areas of Sicily, which were statistically analyzed and compared with other published data from surveys of other communities that have been described for the Tyrrhenian (Sardinia and Corsica) and Balearic Islands up until now. The phytosociological and statistical analysis has led to the description of three new associations two of which are classified in the <i>Oleo-Ceratonion</i> alliance (<i>Ruto chalepensis-Oleetum sylvestris</i> and <i>Chamaeropo humilis-Oleetum sylvestris</i>), the third in the <i>Erico-Quercion ilicis</i> alliance (<i>Calicotomo infestae-Oleetum sylvestris</i>).

title: Smartphone-integrated field microscopy (SPFM): a low-cost and portable tool to study live biological specimens in the wild

description: Images and videos of organisms recorded in the wild have relevance for biodiversity studies. With the advent of smartphones and their potential integration with microscopy, scientific documentation and recording of organisms has surged to an unprecedented scale. Here we report a novel method, developed by integration of a portable smartphone with a handheld field microscope that we term Smartphone-integrated Field Microscopy (SPFM), to capture images and videos which can be highly useful in field-based biodiversity studies. We firstly describe the design of the method and equipment used, followed by successful field demonstration of the method using a case study of the gymnosperm <i>Ephedra intermedia</i> Schrenk & C. A. Meyer in the Kashmir Himalaya. We then discuss the novelty of our method and its potential applications in biodiversity studies.

title: Identification of the areas of endemism (AOEs) of the genus <i>Acantholimon</i> (Plumbaginaceae) in Iran

description: This study was conducted to identify areas of endemism for <i>Acantholimon</i> species using parsimony analysis of endemicity (PAE) and to detect endemic species richness of the genus in the region. The results obtained from the two methods used in this study were used in determining the priorities for the conservation of <i>Acantholimon</i> species in Iran. The distribution database of 62 endemic species belonging to this genus was formed by 1250 georeferenced observations in Iran. The study area was divided into 1̊×1̊ grids of operative geographical units (OGUs) and the species × area matrix including presence/absence data was created. The endemic species richness was calculated using circular neighborhood with a radius of 50 km in 10 × 10 km<sup>2</sup> raster cells using DIVA-GIS software. The results of PAE analysis have shown four areas of endemism (AOEs) in Iran. AOE1: including Alborz and Zagros mountains, the mountains of central Iran. AOE2 and AOE3 are located in Khorassan subregion and AOE4 contains parts of western Iran. The map of endemic species richness indicated that the highest number of endemic species occurs in central Alborz region as well as Kerman, Chahar-Mahal and Bakhtiari, and Isfahan provinces.

title: Priming-induced changes in germination, morpho-physiological and leaf biochemical responses of fenugreek (<i>Trigonella foenum-graecum</i>) under salt stress

description: Seed priming is a simple biotechnological tool which is potentially able to promote seed germination and invigoration as well as seedlings establishment and stress tolerance. In this study, the effects of seed pre-treatment with water (hydro-priming), 100 (HP-NaCl<sub>100</sub>) and 200 mM (HP-NaCl<sub>200</sub>) NaCl (halo-priming) for 6 h on some physiological and biochemical parameters of fenugreek was investigated under saline conditions (100 mM NaCl). For the three priming treatments, no significant changes in the final germination percentage were observed. However, a decrease in seed germination time was observed in hydro- and halo-primed (HP-NaCl<sub>200</sub>) seeds. Salt stress (100 mM NaCl) reduced growth (shoot and root dry weight), pigment content, disturbed the ionic balance and enhanced malondialdehyde content. Salinity-induced changes in lipid metabolism towards synthesis/accumulation of saturated and monounsaturated fatty acids were observed in stressed plants. Seed priming ameliorated the negative effects of NaCl, ensuring significant amelioration on growth, pigment content, increased the activity of catalase and glutathione peroxidase and enhanced the synthesis of very long chain <i>n</i>-alkanes. Taken together, these data provide compelling evidence that priming is an effective alternative that can be used to promote germination and improves establishment and acclimation of fenugreek seedlings under saline conditions.
