Iceland is an island nation located in the North Atlantic Ocean between North America and Europe. It has a population of around 350,000 people and its capital and largest city is Reykjavik. Iceland has a unique landscape defined by volcanoes, hot springs, lava fields, fjords, and beaches made of black sand. The island is split between the North American and Eurasian tectonic plates, which are slowly moving apart and creating new land in Iceland. Fishing is a major industry in Iceland, with cod and haddock being important exports.
Iceland relies on Reykjavik Energy to provide hot and cold water and electricity to homes near and in Reykjavik. Most Icelandic homes have running hot and cold water, with hot water used for heating homes and taking showers. About 90% of energy goes to home heating and 10% to bathing, cleaning and dishwashing. The weather in Iceland is very changeable and can include all types of conditions in a single day, from 20-25°C in summer to below -15°C in winter. Iceland has many rivers, waterfalls, lakes and glaciers that are popular tourist attractions, including the largest glacier, Vatnajökull.

Iceland has many rivers, waterfalls, lakes and glaciers that are popular tourist attractions, including the largest glacier, Vatnajökull.
Iceland was formed from volcanic eruptions approximately 16 million years ago under a hot spot. Glaciers formed around 2500 years ago and were popular tourist destinations until recently declining with rising temperatures. The Gulf Stream ocean current originates in the Gulf of Mexico and warms Iceland's climate. Vikings first settled Iceland in the 9th century after sailing from Scandinavia and discovering many new lands, including Iceland. Within half a century, Iceland was fully settled by immigrants from Norway and Britain. The ocean was Iceland's lifeline for trade, with 14 harbors exporting fish, literature, and imports of Christianity, books, and art from places like Norway, Britain, France, and Germany. Fishing has always been an important industry in

The document summarizes aspects of Iceland's history related to foreign contact and influence. Major plagues in 1402-1403 and 1707-1709 killed approximately 30% and 25% of Iceland's population, respectively. In the 15th century, the British dominated Iceland's fishing and trade markets. After Icelanders had a conflict with the British, Germans replaced them in the 16th century and introduced beer to Iceland. The document also describes a famous Icelandic explorer named Jón who traveled to India in 1622. Additionally, Turkish pirates kidnapped many Icelanders in 1627 to sell as slaves, representing Iceland's largest conflict with foreigners.
The document discusses the history and operation of water wheels. It notes that water wheels were used extensively by ancient Romans and Greeks to grind flour over 2,000 years ago. Water wheels harness the energy of flowing or falling water to turn an axle and power other machines. They were widely used throughout Europe during the Middle Ages to drive mills and other machinery. The document describes the key parts of water wheels and the two main vertical designs - undershot wheels where flowing water strikes paddles from below, and overshot wheels where water falls from above to turn the wheel using both flow and weight.
The moat is a defensive structure used in the Middle Ages to protect castles and forts. It consists of a depression filled with water that is several meters wide and deep, designed to prevent attackers from reaching the castle. The artificially created island in the middle of the moat was usually connected to the surrounding land by a drawbridge. Moats can still be found today surrounding some horse racing tracks, where they serve as obstacles for horses during races.
Floods in the Czech Republic in August 2002 caused by over a week of heavy rain ravaged Europe, killing dozens and causing billions in damages across multiple countries. Prague experienced significant damage, including flooding of the Prague Metro subway system and an estimated $30 million in damage to cultural sites. An estimated 40,000 people were evacuated from Prague. One visible victim was Gaston, a brown fur seal from Prague Zoo, who escaped during the flooding and swam over 300 km down the Vltava and Elbe rivers to Dresden, Germany before being recaptured exhausted and infected.

Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
