Lagosuchus
Lagosuchus is an extinct genus of avemetatarsalian archosaur from the Late Triassic of Argentina . The type species of Lagosuchus, Lagosuchus talampayensis, is based on a small partial skeleton recovered from the early Carnian-age Chañares Formation. The holotype skeleton of L. talampayensis is fairly fragmentary, but it does possess some traits suggesting that Lagosuchus was a probable dinosauriform, closely related to dinosaurs. A second potential species of Lagosuchus, L. lilloensis, is based on an assortment of slightly larger and more well-preserved fossils. These larger specimens have been considered much more diagnostic and informative than the original small L. talampayensis skeleton. As a result, some paleontologists have placed the larger specimens into a new genus, Marasuchus. Marasuchus is generally considered one of the more complete early dinosauriforms, useful for estimating ancestral traits for the origin of dinosaurs. This would also render Lagosuchus a nomen dubium, simply a name referring to a fossil which is too fragmentary to have a formal genus. However, other paleontologists support the argument that Lagosuchus is a valid genus, and that Marasuchus is a junior synonym of it.

Driving Factors on Flood in Cambodia
Flooding in Cambodia, divided into riverine and flash floods, is subject to a multitude of common driving factors. As the MRC rightly noted, flooding in the country can be aggravated by numerous factors, including but not limited to climate change, infrastructure development, dam construction, land cover/use change, or land clearing.

Green Diesel Production by Hydrodeoxygenation
Non-renewable fossil fuels and the air pollution associated with their combustion have made it necessary to develop fuels that are environmentally friendly and produced from renewable sources. Vegetable oils are a renewable source widely used to produce biofuels due to their high energy density and similar chemical composition to petroleum derivatives, making them the perfect feedstock for biofuel production. Green diesel and other hydrocarbon biofuels, obtained by the catalytic deoxygenation of vegetable oils, represent a sustainable alternative to mineral diesel, as they have physico-chemical properties similar to derived oil fuels.

Environmental Monitoring of Pesticide Residues
Pesticide residues are a threat to the health of the global population, not only to farmers, applicators, and other pesticide professionals. Humans are exposed through various routes such as food, skin, and inhalation. Indirect approaches, also called “external exposure approaches”, estimate the exposure of a population through the measurements of pesticide residue levels in food and the environment. Environmental sampling involves water resources, soils, sediments, and air particles. Recent studies have also included indoor and road dust. In addition, indirect assessment models also include food, as fruits, vegetables, and cereals treated with pesticides have also been proven to be significant sources of pesticides. Furthermore, the pesticide residues in abiotic environmental samples also bioaccumulate in biota. Dietary intake of animal products, including meat and subproducts from farm animals, fish, and seafood, is considered an important route of exposure for population.

Geoheritage and Climbing
Geological and geomorphological heritage (geoheritage) is often found in mountain domains that also provide resources for climbing, mountaineering, bouldering, and canyoning. The relevant research is linked to geoconservation, geoeducation, the tourism industry, and tourism opportunities. Several methodologies for assessment of geoheritage and climbing sites are proposed. The world's highest peaks are essential for the relationship between geoheritage and climbing activities.

Black Sea Climate and Ecology
Short-term climatic variation in the Black Sea region is significantly influenced by the operation of the North Atlantic oscillation, the climatic mechanisms resulting from the interaction between the north Atlantic and mid-latitude air masses. While the exact mechanisms causing the North Atlantic Oscillation remain unclear, it is thought the climate conditions established in western Europe mediate the heat and precipitation fluxes reaching Central Europe and Eurasia, regulating the formation of winter cyclones, which are largely responsible for regional precipitation inputs and influence Mediterranean Sea surface temperatures (SST's). The relative strength of these systems also limits the amount of cold air arriving from northern regions during winter. Other influencing factors include the regional topography, as depressions and storms systems arriving from the Mediterranean are funneled through the low land around the Bosporus, Pontic and Caucasus mountain ranges acting as waveguides, limiting the speed and paths of cyclones passing through the region.

Changing Food Consumption Patterns and Land Requirements
The food consumed and the household size determine the land requirement for food. Continued population growth without improved living standards and adequate food production output per hectare will further exacerbate food insecurity and land shortage in Nigeria.

Simulation of Sunspot Cycles
Numerous systems in nature exhibit oscillatory dynamics suggesting common underlying processes. Without knowing an exact interacting mechanism, predictive modelling applied to known count data of a system can provide a non-statistical solution defining its evolution. A recursive difference equation is used to describe the evolution of sunspots and solar cycles in the discrete time domain. Sunspot count for solar cycle 21 is pulse-like over an 11-year period, definable by the product of a pair of growth and decay logistic difference equations. Oscillatory behaviour of multiple solar cycles 22 to 24 up to 2010 are modelled by stabilizing a delayed logistic difference equation.

Zero-Waste City Construction in Xuzhou
The rapidly growing output of solid waste has brought tremendous pressure to urban development. China launched an action plan known as “Zero-waste city” (ZWC), that refers to an urban development model aimed at reducing the generation of and enhancing the recycling of solid waste, in order to alleviate environmental impacts. Xuzhou, as one of the 11 pilot cities selected by the Ministry of Ecology and Environment, is the chosen object of this study. Based on the analysis of material flow and the national policy objectives, five main approaches are put forward in line with the characteristics of Xuzhou, and good results have been achieved in solid waste management through practical experience.
