Assessing Climate Changein Alabama Using Climatenormals, Jonathan Herbert, Jeffrey A. D. Caudill

The Geographical Bulletin

This paper uses climate normals to assess historic changes in temperature and precipitation in Alabama. Changes in temperature and precipitation are calculated between climate normals periods at 18 weather stations across the state and for the state as a whole. The earliest climate normals period for which data are available is 1931-60 and the most recent is 1981-2010. Results show that Alabama has gotten cooler and wetter over the whole period of record, particularly in the fall and winter. However, changes between climate normals periods show these trends are reversing

Analyzing Tornadic Frequency And Regional Climate Change Relationships In Kansas, 1950-2016, Michael S. Molloy, Bimal K. Paul

The Geographical Bulletin

Due to climate change, severe thunderstorms with the potential to produce tornados are expected to be less frequent and more intense over the next several decades. The goal of this research is to determine whether regional climate change is occurring and inf luencing the frequency of tornadic activity occurring in Kansas. Using decadal averages of temperature and precipitation along with decadal tornado totals, we conducted multiple regression analyses to determine if there is a relationship between tornados, precipitation, and temperature from CE 1950 to 2016. We found that four out of seven decades were above the 30-year average of 12.1 …

Synthesis Of An Adaptive Neuro-Fuzzy Control System For Steam Generator Temperature, Isomiddin Xakimovich Siddikov, Dilnoza Maxamadjanovna Umurzakova

Chemical Technology, Control and Management

Modelling Of Heat Transfer In An Air Solar Collector, Shakhnoza Abduvaxitovna Sultanova, Jasur Esirgapovich Safarov, A.A. Mambetsheripova

Technical science and innovation

This study is the prediction, depending on time and different geographical and climatic situations, of different operating parameters: solar radiation, ambient and outlet coolant temperature, heat exchange coefficients and losses. All these determine, in the absence of measurements, the efficiency of the system modelled with existing models with respect to these parameters. These models are usually compared with experimental results. Before modelling, it is necessary to investigate the different heat transfer and exchange regimes that exist between the different elements of this system in order to eventually have a system of equations governing this exchange. The modelling principle is to …

Journal of Engineering Research

This study presents the combustion and emission results obtained from a laboratory furnace equipped with a 35 kW industrial burner that utilizes co-combustion of pulverized biomass and diesel fuel. The experiment compared the co-combustion of pulverized biomass and diesel fuel with diesel fuel alone. Three different loading ratios of pulverized biomass from residual beet samples were used. Temperatures were measured at various positions inside the furnace to analyze combustion performance. It was observed that increasing the biomass loading ratios led to higher flame temperatures and improved combustion compared to diesel fuel alone. The concentrations of pollutants such as Co, HC, …

Mathematical Modeling Of Fruit Drying And System Analysis Of The Process (On The Example Of Persimmon), Gani Dadayev, Jasur Safarov, Shakhnoza Sultanova, Qobiljon Muxiddinov

Technical science and innovation

Vegetable raw materials, as an object of drying, are characterized by a large amount of water and a low content of dry substances. Vegetable raw materials have a capillary-porous structure. Food products contain both bound and free moisture at the same time. The removal of moisture from the material during drying depends on the total moisture content and the form of connection of moisture with the material. Adsorption and osmotic - bound moisture is retained at the interface of colloidal particles with the environment. Food products contain both bound and free moisture at the same time. The quantitative ratio between …

BAU Journal - Science and Technology

Nanotechnology is developing rapidly. This field has many influences in humans’ life. Nanoparticles (NPs) have many unique properties including the size, shape, morphology, and surface area. The synthesis of NPs could be achieved by three ways: physical, chemical, and biological. However, the biological synthesis of NPs has a priority on the other domains due to its safety and environmental friendship. In this regard, the main objective of this study was to synthesize magnesium (Mg) NPs from the bacterium S. haemolyticus which was isolated from the Lebanese wastewater.

Impact Of Marine Heatwaves On The Physiological Health Of Two Fucoid Species, Lily Burnet

The Plymouth Student Scientist

Marine Heatwaves (MHWs) are periods of high-water temperature that have become an increasingly significant threat to marine ecosystem biodiversity in recent decades with rising anthropogenic carbon driving greater severity of MHW events. The two intertidal fucoid species, Fucus serratus and Fucus vesiculosus, are keystone primary producers supporting an extensive biodiverse community of associated flora and fauna. As intertidal species, fucoids are adapted to cope with high atmospheric temperatures during exposure at low tide, however, are prone to changes in abundance, distribution, and life cycles during MHW events. Changes to fucoid communities resulting in reduced primary production and habitat biomass will …

Differences In The Critical Thermal Maximum Between Two Size Classes Of Stenonema Femoratum (Ephemeroptera: Heptageniidae), Jaiden Frantz, David Houghton

The Great Lakes Entomologist

Temperature is an important variable affecting the behavior and survival of aquatic organisms; however, little is known about the effects of size and corresponding developmental differences on aquatic insect temperature tolerance. We tested the critical thermal maximum (CTM) of large (head capsule width mean = 3.5 mm) and small (1.9 mm) specimens of Stenonema femoratum (Say) by raising the experimental temperature by 0.1, 0.3, and 0.5ºC per minute during laboratory CTM trials. Size class and temperature increase rate combinations were randomized, and each combination was tested over four trials, for a total of 24 trials of four specimens each. Two-way …

The Great Lakes Entomologist

Abiotic factors such as temperature and depth are known to affect aquatic insect populations and are thought to be major variables that directly impact how communities are assembled and populations distributed. The purpose of this study was to examine the role of temperature and depth in structuring C. areolaris populations within a temperate freshwater quarry. Larval densities among individual sponges at different depths were determined over six months in a Pennsylvania quarry. Sponges from four depths (7.0 - 8.0 m; 8.1 - 9.0 m; 9.1 - 10.0 m and 10.1 - 12.0) were collected once per month (n = 3) …

Evaluation Of Temperature Effects For Quantum Cascade Laser Dynamics (Qcls), Mushtaq O. Oleiwi, Dhiaa Jabbar Akoosh, Sadeq Kh. Ajeel

International Journal of Thin Film Science and Technology

We introduce a 3-level rate equation approach to modelling a rate equation model for the dynamics of quantum cascade (QCLs) lasers that is based on cascaded active regions. We analyze the evolution of output and carrier numbers at each level taking into account temperature, the effect of the cavity widths, and the specified parameters (injection current density, confinement factor). This leads to an increase in output photons and carrier numbers.

Applications and Applied Mathematics: An International Journal (AAM)

In this study, a one-dimensional layer of a solid is used to investigate the exact analytical solution of the heat conduction equation with space-time fractional order derivatives and to analyze its associated thermoelastic response using a quasi-static approach. The assumed thermoelastic problem was subjected to certain initial and boundary conditions at the initial and final ends of the layer. The memory effects and long-range interaction were discussed with the help of the Caputo-type fractional-order derivative and finite Riesz fractional derivative. Laplace transform and Fourier transform techniques for spatial coordinates were used to investigate the solution of the temperature distribution and …
