Abstract Contaminations by heavy metals in aquatic ecosystems strongly affect foodchain relationships through the process of biomagnification. Heavy metals (i.e. Fe, Cu, Mn, Pb, Zn, Cd, Cr, and Co) were determined from sediment, water and macrophytic species (Ceratophyllum demersum, Phragmites australis, and Potamogeton crispus) of Nigeen lake. The concentration of different heavy metals was determined using atomic absorption spectrophotometer. The concentration of heavy metals was found highest in sediments (viz: Fe- 61.43 ppm, Zn- 56.54 ppm, Cu- 54.77 ppm, Pb-...

General Background Caenorhabditis elegans, or C. elegans are a common worm-like organism that live in the soil of temperate climates. They are eukaryotic, and are often used in biological research as they are very easily characterized and are able to be bred inexpensively and easily. They have two sexes: hermaphrodites which have 956 somatic cells, and males, which have 1031 somatic cells (Department of Molecular, Cellular, and Biomedical Sciences, 2018). Like humans, nematodes have complex systems and specialized cells including...

Abstract As with density, there are typical but not 'abnormal' waste proton concentration values. The urine is typically slightly acidic, about pH 6, but can vary from four.5-8. The kidneys play a really necessary role in maintaining the equilibrium of the body. The study on tongue rolling Reincynomolgus monkey shown that the motor nerves of the medial division of hypoglossol neucleus are connected with the tongue muscles orientated them in crosswise plane to the long axis of tongue and also...

Abstract Silver/Chitosan nanodispersion (Ag/CS) prepared by gamma ray was used to modify the thin-film composite reverse osmosis (RO) membrane. The silver nitrate solutions were added to the chitosan solution with different concentrations of 5 to 20 (wt/wt %) and exposed to gamma radiation at different irradiation doses. The size of the silver/chitosan nanodispersion is investigated by transmission electron microscopy (TEM). The membranes characterized by FT-IR spectroscopy, scanning electron microscope (SEM) and contact angle measurement. Contact angle measurements showed that the...

Abstract The flotation of low-quality lignite coal in the presence of NaCl, MgCl2 and CaCl2 inorganic salts with/without the use of kerosene and MIBC as flotation chemicals was investigated in this study. In addition, the zeta potential and contact angle measurements were performed. The lignite sample exhibited a negative surface charge over a broad pH range and had no isoelectric point (iep). It was determined that the magnitude of negative charge significantly decreased above 10-2 M concentration of the salts...

The Central banks' announcements and government policies influence the trade of commodities. The ECB, recently, hinted towards a rate cut which stimulated the slowing economy in the EU. The inflation expectations and growth have been downgraded over such announcements by the bank. The commodities like base metals copper underwent fluctuation during the trade war, over failing policy-related meetings and the speculation of the global slowdown. Copper price remained in a tight range in the second week of June over the...

Rationale The big issue is that I want to see if chemical reactions will happen faster if they happen at different temperatures. So, I will see if iodine solution and starch solution will react faster if they are at room temperature, at 40 degrees and if they are cold. So, I will be recreating the Iodine Test Background Research: The Iodine test is an experiment which is used to determine the existence of starch. When this chemical reaction occurs the...

Abstract Heavy metals beyond the threshold concentration in nature are often considered as phytotoxic. They cause damage to environment by affecting the soil fertility, biomass, crop yield and the human health. There are various approaches put forth by researches, but the most cost-efficient emerging remedy is been seen as phytoremediation; where the plants are itself involved partially or substantially in remediating heavy metals such as Copper, Arsenic, Nickel, etc from the soil, ground water, surface water.

A waterway is a trademark gushing conduit, normally freshwater, streaming toward a sea, ocean or another stream. Now and again, a waterway streams into the ground and gets dry close to the completion of its course without landing at another waterway.[5] DIFFUSION Is the net development of anything from an area of higher fixation to a locale of lower focus. A slope in focus is driven by diffusion. RIVER CONTAMINATION Is the contamination of water bodies, as a rule in...

“All substances are poisons; it is the dose that makes the poison.”, Philippus Aureolus Theophrastus Bombastus von Hohenheim stated. Heavy metals are commonly characterized as metals with a high toxicity level in high concentrations generally with high atomic numbers, atomic masses, or densities, and those metals are located on the 3rd-15th groups and through the 4th-6th periods. Moreover, heavy metals and the ions formed of them are utilized by our kind heavily in each day, and it is a need...

Inquiry-based learning (IBL) is a student-centered Pedagogic strategy, a process that is ideally led by students. This strategy aims to teach students science by doing it, to attain conceptual change, or accommodate new knowledge, as Jean Piaget's theory of cognitive development claims. To achieve that, students work collaboratively. Build on previous knowledge and one another’s work engaging in active self-directed learning. Find resources, means, and use tools, based on their own formulated questions, and discover appropriate resolutions to questions and...

Introduction Steel often interacts with hydrogen in a variety of ways, especially because steel is used typically in structural components. Today these applications may vary from bridges to the transportation of natural gas, making the knowledge of this interaction useful [1]. Due to its high chemical reactivity, hydrogen can diffuse into the surface of steel and then appear ionically or molecularly in its lattice. Often, the effect of hydrogen on metals can be complex or varied, as it is affected...

Color is found everywhere in nature, ranging from flowers to the vibrant colors of autumn leaves. However, this phenomenon has never been ventured into. What determines nature’s colors, and can this be altered? Does color change with levels of pH? pH is the measure of how alkaline or acidic a substance is. It is measured out of a scale of 14, 7.0 being neutral, anything lower than 7.0 being more acidic, and anything higher than 7.0 being more basic. pH...

Diffusion and barriers affect the impact diseases have significantly. Diffusion is the spread of people, ideas, cultural practices, etc. from one place to another. Barriers are usually associated with something negative, the closing of something. But in the case of diseases it may have positive effects. When barriers such as distance did not allow humans to travel long distances, the spread of diseases was minimal. They mainly affected small, local communities. Nowadays, through the time-space convergence travel is much simpler...

Introduction While coacervates are not alive, they are good representations of how early life may have formed from simple organic substances under the right conditions, which eventually led to the formation of prokaryotes. Under suitable conditions, life-like structures can form naturally from relatively simple materials. In the 1920’s, a scientist named Oparin predicted that biological molecules would form in an acidic mixture of inorganic molecules. In the 1950’s, the Miller-Urey experiment demonstrated that biological molecules could develop from inorganic molecules...

Introduction The purpose of this procedure is to study the impact of various levels of salt in relation to the enzyme catalase during the breakdown of hydrogen peroxide. Catalase is important to the body because it breaks down hydrogen-peroxide from its toxic form (H202) into water and oxygen. Salt, or sodium-chloride, is a necessary electrolyte in maintaining homeostasis within the body, but its role with enzymes was unclear. Hence, to study the specific effect of salt on catalase in the...

The use of recycled materials and hydrogens engines can help the environment and the economy at the same time. Hydrogen engines produce less dangerous emissions than other engine technologies that are currently available to the public. Industrial processes use hydrogen for processing metal, ceramics, electronics, edible oils and other various applications. Once it is used it is then released into the atmosphere. The use of recycled materials could free up other materials to be used in building roads and other...
