Opis:
Introduction. Although airborne fungal diversity in tropical countries is known to be considerable, aerobiological research to-date has identified only a part of the fungal mycobiota that may have an impact both on human health and on crops. Previous studies in Havana city identified only 30 genera and 5 spore types; therefore,new research is required in these latitudes. This study sought to investigate airborne spore levels in Havana, with a view to learning more about local fungal diversity and assessing its influence in quantitative terms. Materials and method. A Hirst type volumetric sampler was located on the rooftop of a building 35 meters above ground level, in a busy area of the city. Sampling was carried out continuously (operating 24hours/day), at 10 L per minute during the year 2015. The fungal spores were collected on a Melinex tape coated with a 2% silicone solution. The results were expressed as spores per cubic meter (spores/m3) of air when to referring to daily values, and spores count if referring to annual value. Results. Fourteen new genera were identified in the course of volumetric sampling: six produce ascospores and eight conidia. Morphobiometric characteristics were noted for all genera, and airborne concentrations were calculated. These genera accounted for 56.4% of relative fungal frequency over the study year. Conclusions. Many airbone fungi are primary causes of both respiratory disease and crop damage. These new findings constitute a major contribution to Cuba’s aerobiological database.

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:
The nature and properties of slag and dust generated during the manufacture of pig iron indicate the two possibilities of their utilization: sintering or cold agglomerating with Portland cement. Both sinter and pellets can be recycled in the LD converter. It was introduced the concept of "preformed synthetic slag" to use the recycling of waste. If the material contains components forming the eutectic properties similar to sinter or pellet (obtained outside the converter) it stimulates the creation of slag in the LD converter.The aim of this research is to address the best way to deal with manganese before the molten metal reaches the final stage of temperature and composition for casting. Ideally, the composition of the slag and dust produced by the BOF-LD can be adjusted so that the molten metal that reaches the secondary metallurgy contains over 1.0% manganese.
Charakter i możliwosci żużla i płynów powstających podczas wytwarzania surówki wskazują na dwie możliwości ich utylizacji: spiekanie lub aglomeracja z cementem portlandzkim. Zarówno spiek, jak i brykiety mogą być poddawane recyklingowi w konwertorze LD. Wprowadzono koncepcję "preformed synthetic slag" do zastosowania recyklingu odpadów. Jeśli ten materiał zawiera składniki tworzące eutektykę z własnościami podobnymi do spieku lub pelet (uzyskanych poza konwertorem), to aktywizuje proces tworzenia żużla w konwertorze LD. Celem niniejszych badań jest znalezienie najlepszego sposobu radzenia sobie z manganem, zanim ciekły metal osiągnie końcowe parametry temperatury i składu do odlewania. Najlepiej gdy skład żużla i wytwarzanego przez konwertor pyłu mogą być dostosowane tak, aby ciekły metal, który trafia do obróbki pozapiecowej, zawierał ponad 1,0% manganu.

Opis:
The influence of the type of farming on harmful gas exposures to carbon dioxide (CO2), ammonia (NH3) and hydrogen sulfide (H2S) was assessed from the perspective of animal welfare and occupational hygiene. Summer data of H2S, NH3 and CO2 concentrations and of environmental parameters were collected from 31 farms. The indices of exposure for longterm exposures to NH3 suggest the lowest acceptability of exposure was observed on poultry farms. CO2 had the highest dependence on production activity. For H2S, no differences were found based on farming activity. Both the stocking density and volume of air available affected the daily exposure and the index of exposure to CO2. Significant differences were observed between hourly CO2 concentrations, depending on the level of activity inside the building. A positive correlation was found between gas concentrations and temperature increase. All values of daily and short-term exposures were below exposure limit values, which suggests that exposure conditions were appropriate for workers’ health during the measurement period. Analysis of the working hours and average hourly concentration of gases during the times of day, with presence of workers inside the farm buildings, revealed significant differences for CO2.

Opis:
Here we report a new Early Pleistocene record of agamid lizards (Agamidae indet.) from the Spanish locality of Quibas (ca. 1.3–1.0 Ma), which represents the latest evidence of the family in Western Europe. Up to now, the family Agamidae was considered to have disappeared in this region at 1.8 Ma. This new record implies the survival of agamid lizards for a large part of the Early Pleistocene in the southernmost Iberian Peninsula, probably because of favourable climatic and environmental conditions. Consequently, the formerly detected Pliocene / Pleistocene boundary is no longer recognisable in the evolution of the herpetological assemblages in Western Europe.

Opis:
This study describes a novel spectral LED-based tunable light source used for customized lighting solutions, especially for the reconstruction of CIE (Commission Internationale de l'Eclairage) standard illuminants. The light source comprises 31 spectral bands ranging from 400 to 700 nm, an integrating cube and a control board with a 16-bit resolution. A minimization algorithm to calculate the weighting values for each channel was applied to reproduce illuminants with precision. The differences in spectral fitting and colorimetric parameters showed that the reconstructed spectra were comparable to the standard, especially for the D65, D50, A and E illuminants. Accurate results were also obtained for illuminants with narrow peaks such as fluorescents (F2 and F11) and a high-pressure sodium lamp (HP1). In conclusion, the developed spectral LED-based light source and the minimization algorithm are able to reproduce any CIE standard illuminants with a high spectral and colorimetric accuracy able to advance available custom lighting systems useful in the industry and other fields such as museum lighting.

Opis:
Fruit quality attributes are influenced by environmental, agronomic and genetic factors; both cultivars and growing conditions can vary substantially between UK production and imported fruit. This study aimed to record and dissect the most relevant fruit quality traits for berries imported into the UK in the winter months. Blackberry, blueberry, raspberry and strawberry fruit were imported from 11 countries into a Kent-based packhouse (UK) or purchased from major retailers between December 2018 and March 2019. Multiple fruit quality components were assessed for relative contribution towards a high “overall assessment” fruit quality score. It was found that strawberry and blackberry overall scores were affected by sweetness perception, whereas blueberry and raspberry organoleptics are more complex, with overall scores influenced by flavor perception. Multiple raspberry and strawberry fruit quality traits were found to be associated with genotypic differences, indicating a promising potential for genetic improvement through breeding. By contrast, the study findings suggest that there is less potential for genetic improvement in blueberry, and that the environment may have a large effect on blueberry fruit quality traits.

Opis:
In this paper we study the degeneration of both the cohomology and the cohomotopy Frölicher spectral sequences in a special class of complex manifolds, namely the class of compact nilmanifolds endowed with a nilpotent complex structure. Whereas the cohomotopy spectral sequence is always degenerate for such a manifold, there exist many nilpotent complex structures on compact nilmanifolds for which the classical Frölicher spectral sequence does not collapse even at the second term.

Opis:
In spite of the diamagnetic behavior exhibited by bulk ZnO and Au, a ferromagnetic-like behavior is induced in nanoparticles of both systems by appropriate surface functionalization. By capping with thiol derivatized molecules, magnetic hysteresis is observed even at room temperature, whereas the magnetization has a very little temperature dependence. Capping induces an alteration of their electronic configuration that depends on the capping molecule, as evidenced by X-ray absorption spectroscopy, that strongly affects their magnetic properties.
