Cocconeis dapalistriata, first described as a member of the genus Cocconeis, is re-examined due to its unique ultrastructure. Both valvocopulae of this taxon show significant differences compared to those found in the genus Cocconeis. They are expanded and show some similarities with those found in Amphicocconeis. On the other hand, terminal parts of the raphe valve (RV) in C. dapalistriata are simple and the raphe valve (RV) striae are composed of small round areolae with a hymenate occlusion with radial slits, similar to those observed in Cocconeis. Campyloneis and Xenococconeis also have expanded valvocopulae but with numerous morphological differences compared to those found in C. dapalistriata. Furthermore, the areolae of the sternum valve (SV) in C. dapalistriata are occluded by a concave velum with no apparent internal slits, and externally ornamented with irregular silica crystals. Upsilococconeis Riaux-Gobin, Witkowski & Risjani gen. nov. is proposed to accommodate the latter taxon. First described from the Western Indian Ocean (Mascarenes), it was subsequently listed from the Western Pacific Ocean (Guam), the South Pacific Ocean (French Polynesia and New Caledonia) and from the Eastern Indian Ocean (Indonesia), and thus may qualify as pantropical.
Sustainability or fun? Recreational angling in Marine Protected Areas
Authors: Cerim Hasan
Published: May 2022

Gökova Bay MPAs (southern Aegean Sea, Turkey) include six different no-take zones (NTZs: Akyaka, Çamlı, Akbük, Boncuk-Karaca, İngiliz Limanı, Bördübet), in four of which shore angling is permitted (Akyaka, Çamlı, Akbük, Boncuk-Karaca). This study determined the total catch and size of fish caught in the Akyaka MPA during recreational fishing. In total, fish representing 22 species belonging to 10 families were caught and most of them were smaller than their length at first maturity. The projection showed that the total catch weight reached significant values for recreational angling in the Akyaka MPA. The results of this study indicate that recreational angling may pose a threat to both MPAs and no-take zones, causing them to deviate from their primary conservation goal due to the harvesting of juveniles by recreational anglers.

Gato andino (Leopardus jacobita, CORNALIA 1865) en carretera: nueva amenaza para su conservación
Authors: Kaiser Melanie , Hernández-Hernández Julio , Guzmán Marín Byron Cristian
Published: May 2022

El gato andino (Leopardus jacobita, CORNALIA 1865), habitante de las regiones áridas de los altos andes y la estepa patagónica, está clasificado como En Peligro por la Unión Internacional para la Conservación de la Naturaleza. Entre las mayores amenazas enfrentadas por la especie están la degradación y fragmentación de su hábitat, relacionadas principalmente con la actividad minera. También ha sido objeto de caza, pero la interacción directa con el humano ha sido poco frecuente debido a la gran distancia entre el hábitat del félido y los centros de actividad antrópica. Sin embargo, la continua ampliación de la red vial en conjunto con el aumento de tráfico a lo largo del rango de distribución de L. jacobita, han provocado encuentros con la especie en ruta. En la presente nota, reportamos por primera vez hallazgos de gato andino cruzando carreteras y otros caminos vehiculares, lo que implica un peligro inminente de atropellamiento. Los registros fueron recopilados en el contexto de un proyecto de ciencia ciudadana y completados por un informe de una agencia estatal. Dado su frágil estado de conservación y la baja densidad poblacional del gato andino, la muerte de pocos animales puede tener efectos adversos desproporcionados sobre la especie. Por lo tanto, se recomienda el desarrollo de estrategias de prevención de atropellamientos como parte de los planes de conservación de L. jacobita.

Authors: Konstantinos Tsikouras  , Dimitrios Giotis  , Christos Konstantinidis
Published: May 2022

The global escalation of terrorist and felonious assaults in the civilian environment along with the Emergency Medical Services lack of training in tactical emergency casualty care lead the police forces to look for new training strategies regarding penetrating trauma management from Law Enforcement Personnel. USA police agencies approached the military committee for guidelines due to similarities presented between civilian incidents and warfare. Therefore, modified Tactical Emergency Casualty Care programs were developed. These programs were also adapted by the Hellenic Police Force, along with German, Italian, French and British Police. The aim was to elevate Law Enforcement Officers medical knowledge and practical skills in bleeding control, tension pneumothorax and airway management using hemostatic dressings, tourniquets, decompression needles and nasopharyngeal tubes respectively, in an ongoing situation. It is evident that LEOs training nowadays is more demanding as far as it concerns severe and life-threatening injury management, resulting to increased self-confidence and medical skill development. On the other hand, such training should be accessible and cost-efficient to the majority of field-operating personnel.

Предложена обобщенная двустадийная модель химической кинетики детонационного горения двухтопливной стехиометрической смеси синтез-газа с окислителем. Модель позволяет рассчитывать тепловой эффект химической реакции, молярную массу и внутреннюю энергию смеси без расчета ее детального химического состава. Разработан алгоритм расчета периода индукции химической реакции в рассматриваемой двухтопливной смеси, основанный на формулах для расчета периода индукции в однотопливных смесях каждого из горючих компонентов. Сделан двумерный численный расчет ячеистой многофронтовой структуры детонационной волны (ДВ) в стехиометрической смеси синтез-газа с воздухом при различном соотношении между горючими. Химические превращения описывались предложенной кинетической моделью. Полученный размер детонационной ячейки, а также качественная структура ДВ (в том числе ее перестройка от регулярной к нерегулярной при увеличении концентрации оксида углерода) хорошо соответствуют эксперименту.
Modelo estadístico para determinar el consumo de gas natural en áreas urbanas: La Plata -Argentina-
Authors: Chévez Pedro Joaquín
Published: May 2022

El presente trabajo plantea la construcción de un modelo estadístico de regresión múltiple basado en información censal que permite estimar el consumo de gas natural por usuario en una determinada área urbana. Este modelo fue testeado en una hipotética expansión urbana, para la cual se evaluaron quince posibles morfologías. Para cada una de estas se obtuvo el consumo de gas natural con el fin de identificar la configuración urbana más eficiente. El modelo obtenido cuenta con un R2=0,60 y permitió identificar variables clave en la determinación del consumo de gas natural que, para La Plata, resultaron: el porcentaje de departamentos, el promedio de habitaciones por hogar y el porcentaje de personas inactivas. La metodología aquí desarrollada puede ser replicada en otros casos de estudio de similar escala, con sus adecuaciones pertinentes; puede generar argumentos específicos para cada caso a la discusión entre ciudades compactas y difusas; y, además, puede contribuir en la toma de decisiones en materia de planificación urbana a partir de un enfoque energético.

Purpose. A review of the current literature, regarding the existing approaches used to estimate the lightning perfor-mance of overhead power lines, was performed. A review of available lightning activity data over India was also per-formed. Methodology. The electro-geometrical model was chosen to analyze the lightning performance of overhead power lines. International normative documents and national standard were used to highlight the main parameters that should to be paid main attention to when estimating lightning performance of overhead power lines. Results. Presently, approaches from IEEE and CIGRE guides can be used for analysis of statistical distributions of lightning current pa-rameters. Further studies are required on thunderstorm days, ground flash density and current parameters statistical dis-tributions for different locations, which will be supportive in performing analysis for Indian power lines. Originality. To graphically analyze the shielding failure mechanism with a help of electro-geometric model, the sketch of real 220 kV double-circuit transmission line tower was used. Using electro-geometric model it was graphically shown how downward lightning leader that propagate from thunderstorm cloud toward ground can finish its path on the overhead shield wire, phase conductor or ground plane. Practical value. Available data on lightning activity over different parts of India are still not enough complete. It is of great importance to obtain reliable statistical data on thunderstorm characteristics in the area of the studied power line route. Measurement techniques based on satellites have limitations in obtaining ground flash density values. Thus, for India there is a need in development of modern lightning detection networks and related studies on lightning characteristics. Conclusions. Future efforts should be focused on obtaining not only the positions and number of lightning strikes to the overhead power line, and calculation of lightning flashover rate parameters, but also the statistical distributions of lightning current values and related overvoltage parameters at the overhead wires and different phase conductors.

Purpose. Improving the heat resistance and corrosion resistance of carbon steels can be achieved by applying to their surface coatings based on molybdenum and silicon, niobium and silicon, vanadium and silicon, chromium and silicon, which form on the surface protective films of oxides. In this work properties of chromosilicide diffusion coatings applied to steel 45 obtained by the gas method are investigated. Methodology. Diffusion chromosilicide coatings were applied to steel 45 by the gas method. The process was carried out for 6 hours in a closed reaction medium at the pressure of the active gas phase (106 Pa) and a temperature of 1323K. In the work wad studied phase and chemical compositions of diffusion coatings. The heat resistance of the coatings was studied in a specially designed shaft furnace. Corrosion tests were performed by massometric method .The electrochemical behavior of steel and coated steel was studied by the method of removing polarization curves on the potentiostat PI-50.1.1. Results. X-ray diffraction layer analysis revealed that the diffusion layer on the surface of steel 45 consists of two zones - the outer (10–15) 10-6 m, which contains chromium carbides Cr23C6 and Cr7C3 and inner (60–80) 10-6 m, which consists of a solid solution of silicon and chromium α-Fe. The total thickness of the coatings is 100 μm. Microhardness – 19.5 GPa. It was found that chromosilicide coatings obtained by the gas method have high heat resistance up to 1000 С. It is shown that diffusion chromosilicide coatings oxidized at temperatures of 700–800С have higher corrosion resistance in various aggressive environments and a more stable passive state than non-oxidized ones. The degree of protection reaches 99,92–99,99%. Based on the research, a new method of diffusion coatings on the surface of carbon steels with subsequent oxidation was proposed. Practical value. Chromosilicide coatings can be recommended for the protection of machine parts operating at elevated temperatures in various aggressive solution. References 20, tables 1, figures 3.
