Sea-level rise and Extreme Sea Level Eventsipcc-media
This document discusses projections for sea level rise and extreme sea level events from climate change. It notes that Antarctic ice sheet contributions to sea level rise were revised upwards in recent reports. Without sharp reductions in emissions, sea level rise may exceed 1 meter by 2100 and extreme sea level events could become at least 100 times more frequent at most coastal locations before 2100. The document also warns that many tropical islands and low-lying cities will face annual flood risks by 2050 under any emissions scenario without strong adaptation efforts, and sea levels could rise up to 5 meters by 2300 if emissions are not cut.
A hurricane hitting the coast causes warm surface water to sink into cooler deep water, dramatically warming the overall ocean temperature and potentially fueling another storm. It can also kill thousands of people through flooding and property destruction. Repeated hurricane impacts over time can significantly erode coastal land like in Louisiana, where estimates show the state may completely erode in 200 years due to these effects.
The greenhouse effect occurs when an earth warmed by the solar spectrum radiates invisible infrared light back, but, instead of going back to space, it is partly absorbed by greenhouse gases in the atmosphere, making the atmosphere warmer. Substantial areas of North America are likely to have more frequent droughts of greater severity. Hurricane wind speeds, rainfall intensity, and storm surge levels are likely to increase. The strongest winter storms are likely to become more frequent, with stronger winds and more extreme wave heights. Presentation courtesy of Dr. Walter Hays, Global Alliance for Disaster Reduction
Oceans cover most of the Earth's surface and contain nearly all of its water. Sea levels are rising at about 10 times the rate over the past 3,000 years due to global warming, which is causing oceans to increase in size. Rising sea levels threaten coastal areas through increased erosion, flooding, and damage from storms. Scientists project that by 2100, sea levels could be 0.8 to 2 meters higher than current levels without action to address climate change.
1) Burning fewer fossil fuels and reducing emissions of methane, ozone, hydrofluorocarbons, and black carbon could help prevent sea level rise by 25-50%, according to a new study. This includes less fracking, vehicle exhaust, and industrial emissions.
2) Sea level rise is caused by thermal expansion as oceans warm and increased melting of land ice like glaciers and ice sheets. Over 90% of increased heat from human emissions is absorbed by oceans.
3) Sea level is primarily measured using tide stations that measure water height relative to land, and satellite laser altimeters that measure average ocean height globally.
Potential and realized consequences of climate change include:
1) Drought, melting ice, rising sea levels, and permafrost melt are already occurring as a result of climate change.
2) Additional potential consequences that some experts say may already be happening include altered ocean circulation patterns and more extreme weather events.
3) Further potential consequences include threats to biodiversity like coral bleaching and disrupted animal migration patterns, shifting agricultural production, and risks to human health from factors like heat waves.
An overview of the scientific evidence that climate change is occurring, and what was normal in the past is not going to be normal for the future. Recent extreme-weather events -- snowstorms, last summer's derecho, and two severe hurricanes in the space of just over a year, are harbingers of more to come. Because the future will be different, we must use future-based modeling rather than historical data to prepare.

Sea levels are rising due to global warming caused by human emissions of greenhouse gases. The two main causes of sea level rise are the thermal expansion of ocean water as it warms and the melting of land ice sheets and glaciers. Current estimates show sea levels rising 3.2 mm per year globally but faster in some areas, threatening coastal communities with problems like flooding and erosion. To mitigate further dangerous sea level rise, experts recommend reducing greenhouse gas emissions by 80% by 2050, though even that may only limit warming to 4-6 degrees Celsius by 2100.
The climate change refers to changes in modern climate caused primarily by global warming due to high levels of CO2 in the atmosphere. It affects the poles the most where temperatures are rising quickly, melting ice and snow, and also impacts mountains. The effects include a rise in sea levels of over 10 meters from melting poles that could flood coastal cities, changes in rainfall that may lead to droughts, and mass death of plants and animals potentially resulting in food shortages and loss of human lives. The primary causes are pollution that is increasing sun's heat on earth, destruction of the ozone layer, and wasteful energy usage.

This document summarizes the significant earthquake that struck Christchurch, New Zealand on February 22, 2011. It was a magnitude 6.3 earthquake located close to the city, causing more severe shaking than the 2010 earthquake. Initial reports found ground shaking exceeded typical building design standards, resulting in widespread damage and collapsed structures. Emergency responders worked to rescue trapped survivors amid ongoing aftershocks. The earthquake will likely result in billions of dollars in losses and place a significant burden on recovery efforts still underway from the prior quake.
The document discusses factors that influence climate. It describes how air circulation driven by differences in solar heating across the Earth's surface creates global wind patterns. Ocean currents distribute heat around the world and interact with atmospheric circulation. Surface features like mountains also impact climate by influencing precipitation. All of these factors together define the world's major biomes by controlling temperature and rainfall in different regions.

The document discusses the effects of earthquakes, including deformed ground, damage to structures and cities, loss of life, fires, landslides, floods, and faults. It notes that earthquakes can occur without warning, so it is important for homeowners to prepare emergency kits and reinforce structures. Newer buildings in California are often designed to withstand earthquakes, while older structures may not hold up as well. The document defines earthquakes as intense shaking caused by rock fractures along fault lines, which are specific locations that scientists monitor.
This document provides information about GCSE Geography revision on dynamic planet topics. It includes case studies on volcanoes like Mt St Helens and Nyiragongo, as well as earthquakes in Kobe, Japan and Sichuan, China.

Review materials include theory, graphs to interpret, and guidance on key topics to know for the exam.
New zealand and the christchurch earthquake 2lavenderbongo
The document provides information about the 2010-2011 Christchurch earthquakes in New Zealand. It details that the first earthquake on September 4, 2010 was magnitude 7.1 and centered near Darfield. The more destructive earthquake was on February 22, 2011 with a magnitude of 6.3 centered 10km southeast of Christchurch. This earthquake caused widespread damage in Christchurch and 181 deaths. Analysis showed the earthquake was caused by movement along a previously unknown fault running beneath the southern edge of Christchurch.
Rising sea levels are caused by thermal expansion as the oceans warm and the melting of ice sheets and glaciers. This will lead to billions being spent on adaptation, the submerging of cities, displacement of rural populations, and flooded farmland. The consequences include submerged island nations, contaminated water, and destruction of ecosystems. Even if rising sea levels are addressed, the heat mixed into deeper ocean layers means sea levels may continue increasing for hundreds of years.
Rising Seas and Solutions, Sigma Xi LecturePaul H. Carr
Miami Beach becomes a flood zone during King High Tides. The melting of Greenland, mountain glaciers, and thermal expansion is raising sea levels four times faster than in 1900. Sea level rises of 2 to 6 feet are predicted by the end of the century. Flood highs from hurricanes Sandy and Katrina were ~ 10 feet.
The article “Treading Water” in the February 2015 National Geographic tells how Dutch Docklands LLC sees profit not loss from rising sea levels. They are building floating homes in Miami, FL. A floating classroom could assure Eckerd Colleges's long-term future. It would provide a place to meet in the event of flooding by the 10-foot ocean surges that accompany hurricanes.
Dr. Carr describes how increasing greenhouse gases, mostly carbon dioxide from the burning of fossil fuels, trap the radiation that is warming our planet. Advances in non-carbon emitting energy sources can reduce global warming. Solar PV panels are now generating electricity at $0.07/kWhr, less than the national utility average of $0.12kWhr. Rising sea levels are a better measure of global warming than atmospheric temperature, as 90% of our planet’s heat content is in our oceans.

Climate change is caused by greenhouse gases in the atmosphere that trap heat. The top causes of greenhouse gases are power production, transportation, and farming. If heat is unable to escape the atmosphere, the Earth's climate will get warmer. Some consequences of climate change include ozone depletion, rising sea levels from melting glaciers, melting permafrost, and spread of pests and diseases. International agreements like the Kyoto Protocol aim to reduce emissions to pre-1990 levels to limit global temperature rise to under 0.1°C per decade and sea level rise to under 20mm per decade. Over the next 50 years, the climate is projected to continue warming with rising temperatures and sea levels along with more extreme weather like rains,
The document discusses the impacts of climate change in Bangladesh and the challenges it faces. It outlines how Bangladesh is vulnerable to climate change due to factors like sea level rise, increased cyclones, erratic rainfall patterns and floods. It also summarizes the potential consequences of climate change stressors like increased temperatures, variations in precipitation, sea level rise and more frequent extreme weather events. Finally, it provides an overview of Bangladesh's national policies and adaptation programs to address climate change impacts.
The document discusses climate change and its causes. It provides the following key points:
1) In 2008, 193 countries signed an anti-CO2 emissions treaty, except the USA and China. The USA did not believe in global warming under Bush, and China profits from natural resources.
2) The industrial revolution beginning in the 1800s caused a rise in CO2 levels and global temperatures.
3) Human activities like burning fossil fuels are major contributors to increased greenhouse gas emissions and climate change. This will have severe environmental and economic impacts worldwide if left unaddressed.
The document provides study notes on ecology and chemistry. It discusses key topics like the atmosphere, weather, climate, climate change arguments, factors that affect climate such as the sun and greenhouse gases. It also covers chemistry topics such as ionic compounds, naming conventions, types of reactions, acids and bases.

This document summarizes information presented at a workshop on using the Sea Level Affecting Marshes Model (SLAMM) to project impacts of sea level rise on coastal wetlands in Rhode Island. Key points include:
- Tidal marshes provide important ecosystem services like habitat, water filtration, and flood protection. Rhode Island has lost over 50% of its historic salt marshes.
- Sea levels are rising faster in Rhode Island due to climate change, increasing the risk of wetland loss and property damage from flooding. The SLAMM model projects significant wetland loss under scenarios of 1, 3, and 5 feet of sea level rise.
- The SLAMM projections will help identify vulnerable wetlands and
Paul Gilliland Marine Planning in England What are we learning?riseagrant
Marine planning in England aims to balance competing uses of marine space and resources through a process established by the Marine and Coastal Access Act 2009. The legislation requires marine plans that translate high-level national policies into spatial guidance for regional plan areas. The first plans are being developed for the East marine plan areas through stakeholder engagement, evidence gathering, and defining key issues to guide sustainable decisions about marine activities. Challenges include the complexity of planning at a large scale across environmental, economic, and social factors while balancing competing interests. Lessons indicate the need for political commitment, dedicated resources, and flexibility in the long-term planning process.

2015 International Spatial Planning Symposium: Sharing Practical Solutions riseagrant
The document summarizes findings from a review of marine spatial plans around the world. It finds that most plans are implemented at smaller spatial scales than entire ecosystems. It also finds that few institutional changes are made to governing bodies to implement coastal and marine spatial planning, relying instead on existing agencies. Additionally, it notes that while formal decision support tools are used, informal expert judgment also plays a role. The main messages are that there is no single approach for marine spatial planning and that the value is in the planning process of engaging stakeholders as much as the final plan.
Legal and Policy Strategies for SLAMM in Rhode Islandriseagrant
This document discusses potential legal and policy strategies for addressing sea level rise and marsh migration in Rhode Island. It examines transferred development rights and rolling easements as adaptive tools, noting that the strategies were researched by Sea Grant Law Fellows to help inform the SLAMM and Beach SAMP teams. The Beach SAMP process will further explore using these strategies as well as property rights and liability issues related to climate change impacts.
This document summarizes coastal wetland adaptation strategies presented at two municipal workshops in October 2014. The strategies included upland actions like facilitating marsh migration and removing barriers, as well as in-marsh actions like drainage improvements, elevation enhancement, and erosion control. Specific project examples were provided from locations around Rhode Island where marsh migration was being facilitated or impeded, and adaptation techniques like creek excavation and land protection were undertaken. Partnerships between municipalities, land trusts, and state agencies were noted as important for implementing projects costing $5,000 to $15,000 each to adapt coastal marshes to sea level rise.
Five regional planning bodies have been established across the United States to coordinate ocean planning: the Northeast, Mid-Atlantic, Pacific Islands, Caribbean, and West Coast. The Northeast and Mid-Atlantic regions have established charters and are drafting regional marine plans to be completed in 2016. The Pacific Islands has a charter and is beginning to draft a plan, while the Caribbean is still finalizing its charter and the West Coast is working on one.
Projections of Future Tropical Cyclone Activityriseagrant
The document summarizes projections of future tropical cyclone activity from a panel of experts. It finds that while the overall global frequency of tropical cyclones may decrease or remain unchanged, intensity is likely to increase, with more intense storms. Rainfall rates from tropical cyclones are also likely to increase. There is uncertainty around potential changes in other storm characteristics and impacts on specific regions. Sea level rise exacerbates storm surge risks along U.S. coastlines including in Rhode Island.
Rhode Island Wind Power Resource Assessmentriseagrant
The document discusses Rhode Island's wind power resource assessment, which was conducted by a team from the University of Rhode Island's Ocean Engineering department and analyzed wind speed data and maps, bird migration patterns, conceptual frameworks for energy assessments, and the theoretical and technical wind resources in the region. It also covers vertical wind profiles, wind farm siting considerations regarding ecosystem services and environmental impacts, and methods for modeling and measuring wind resources.
This document summarizes several local case studies on coastal communities in Rhode Island that are vulnerable to sea level rise. It describes modeling of 1 foot, 3 foot, and 5 foot sea level rise scenarios for the communities of Jamestown, Barrington/Warren, and Charlestown. For each community, the document identifies current land uses and infrastructure that are at risk of flooding and inundation. It also provides potential issues and opportunities to address the impacts of sea level rise through actions such as elevating roads, relocating facilities, protecting undeveloped lands, and coordinating land management between stakeholders.

This document summarizes Vera Agostini's work with The Nature Conservancy on marine spatial planning from a tropical perspective. It discusses TNC's work in Raja Ampat, Indonesia, Saint Kitts and Nevis, and Samana Bay in the Dominican Republic. Common challenges faced in these areas include lack of information, rapid development, limited funding and enforcement capabilities. The document outlines TNC's approach to marine spatial planning, which involves developing a clear vision, gathering baseline data, stakeholder engagement, supporting decision making, and building long-term governance. It also notes some questions from organizers on evaluating environmental and societal outcomes of marine spatial planning.

Wind Turbine Shadow Professor Gopu Flicker 2riseagrant
Shadow flicker occurs when the sun passes behind the rotating blades of a wind turbine, casting shadows that flick on and off nearby properties. The likelihood and duration of shadow flicker depends on several factors like direction, distance from turbine, time of year and day. It can potentially cause health issues like seizures and headaches. Regulations in some places limit shadow flicker to 30 hours per year or 30 minutes per day. Signal interference is also possible within a few hundred feet but cellular networks are usually not affected. Guidelines recommend considering and minimizing any interference.
About 75% of the US population lives in coastal areas and faces coastal hazards. These hazards include tropical cyclones, storm surges, tidal floods, tsunamis, erosion from wave action and fluctuating sea levels, and deposition from littoral sediment transport. Coastlines are divided into littoral cells that contain a complete cycle of sedimentation, and interference with sediment transport within a cell can lead to downcoast beach erosion. Coastal hazards vary depending on whether the coast is on a passive or active tectonic margin.
Tropical cyclones, flooding, and storm surges are coastal hazards that can cause substantial impacts as about 75% of the US population lives in coastal areas. Coastal hazards vary depending on the type of ocean margin, which are generally divided into passive and active margins related to plate tectonics. Sediment transport within littoral cells, the natural compartments that contain the cycle of sedimentation along a coastline, is important for regional coastal management and can be interfered with by structures.
This document summarizes a presentation given by Dr. Adam Sobel on Hurricane Sandy and climate change. The presentation discusses Sandy's impacts, including over 100 deaths and $50-65 billion in damage. It analyzes forecasts and preparations for the storm, noting both wise short-term decisions that saved lives, as well as infrastructure that was unprepared. The presentation also discusses the link between climate change and hurricanes, noting uncertainty about future storm characteristics, but a clear link between climate change and rising sea levels which exacerbate storm surge impacts.
Rising sea levels are a global concern, several coastal cities and island will submerge undersea. to sustain this climate / environmental change, we might need to shift our habitat from land to ocean.
This document summarizes research on the impacts of climate change and how factors like rising sea surface temperatures and sea levels influenced Hurricane Sandy in 2012. It discusses observed trends in climate extremes from a UN report and projections for further temperature rise and sea level rise. Specific impacts to coastal flooding and hurricanes from rising seas are examined. The potential for even worse storms is considered if a storm like Sandy occurred during high tide or with warmer ocean temperatures like Irene. The risks of more frequent damaging flooding events in coming decades is also summarized. The document outlines ongoing modeling efforts to better understand how climate change may impact conditions in the Long Island Sound.
This document discusses several impacts of climate change from an oceanographic perspective, including ocean warming, sea level rise, and ocean acidification. It notes that these issues are worldwide in scope and linked to increasing CO2 levels. Specific impacts highlighted include more intense hurricanes, rising seas threatening coastal populations like in Bangladesh and the Maldives, and harm to coral reefs and other organisms from acidification. The human impacts discussed include increased environmental refugees, effects on health, and the potential for conflict. The document raises the possibility of approaching a tipping point and examines geoengineering as a potential remedy for climate change, but notes the risks of such large-scale intervention.

Most of the document discusses various coastal hazards such as hurricanes, tsunamis, rip currents, and erosion. It describes the processes that cause these hazards, including storm surge, waves, and sea level rise. It also discusses how population growth has led more people to live near coasts, exposing them to these risks. Finally, it examines various mitigation approaches like elevating buildings, early warning systems, and engineered structures to manage shoreline change.
Oceans cover most of the Earth's surface and contain nearly all of its water. Sea levels are rising at about 10 times the rate over the past 3,000 years due to global warming. As a result, coastal areas are experiencing problems like erosion and damage from higher tides and stronger storms. Scientists predict that by 2100, sea levels could be 0.8 to 2 meters higher than today if warming continues unabated.
The document discusses natural disasters throughout history and how climate change may impact their frequency and intensity in the future. It outlines different types of natural disasters and provides examples from the past. It then explains the mechanisms through which greenhouse gas emissions and rising temperatures could alter atmospheric and oceanic conditions in a way that aggravates natural disasters. This includes increasing sea surface temperatures that fuel stronger hurricanes, and changing precipitation patterns that may lead to more floods or droughts. The document ends by discussing how the media raises awareness of natural disasters and their links to climate change through movies and documentaries.

NJFuture Redevelopment Forum 13 Climate Change BroccoliNew Jersey Future
The document summarizes key points from a presentation by Anthony Broccoli on planning for future weather extremes in New Jersey. Broccoli discusses recent extreme weather events like hurricanes Irene and Sandy. He questions assumptions of a "normal" climate and whether these events indicate a "new normal" with more frequent extremes due to climate change. Broccoli reviews climate science findings on trends in hurricanes, heavy precipitation, heat waves and sea level rise. He argues that past weather patterns are no longer a reliable guide for the future and emphasizes preparing for climate impacts even amid uncertainties.

The document provides information about various geographic concepts. It defines key terms related to rivers such as erosion, transportation, and landforms. It also discusses coastal landforms and processes, population dynamics, hazards from climate, tectonics and urbanization. Settlement patterns are examined using models like the Burgess model and concepts of threshold populations and spheres of influence.
The document provides information about various geographic concepts. It defines key terms related to rivers such as erosion, transportation, and landforms. It also discusses flooding, tropical storms, earthquakes, volcanoes, population, and settlement patterns. Specifically, it explains river erosion and transportation processes, landforms in the upper, middle and lower courses of rivers, physical and human causes of flooding, storm surge definition, effects of tropical storms, differences between Richter and Mercalli scales, earthquake focus and epicenter, volcano types, and population distribution, density, and models.
The document discusses several key climate factors that influence a region's climate:
1) Proximity to oceans and seas regulates temperatures, while distance from oceans leads to greater seasonal variation. Ocean currents also influence temperatures.
2) Prevailing winds can push warm or cold air currents and affect storm patterns.
3) Elevation impacts temperature, with mountainous areas generally cooler and low-lying coastal areas warmer.
4) Proximity to the equator determines temperature, with areas closer to the equator experiencing warmer climates.
The document analyzes tide gauge data from five locations in the UK to determine historical sea level rise. It finds an average rise of 1.56mm per year over the period of available data for each location. However, sea level rise varies locally due to land movement. GPS data shows southern England is subsiding by up to 1.2mm/year while Scotland rises by 1-2mm/year, influencing relative sea level changes. Accounting for these land movements, sea levels have risen by 0.9-1.1mm/year independently of land movement effects. Rising sea levels are a concern for coastal areas due to potential flooding impacts.
Similar to Rising Seas and Extreme Storms: Similarities and differences (20)
This document assessed the impact of past ocean management plans in several countries and U.S. states. It found that the plans supported $4.1 billion in ocean economies by siting wind farms and retaining existing industries. The plans also generated hundreds of millions of dollars annually in economic gains for new industries like wind power and retained billions within existing industries like fishing and tourism. While fishermen lost some access, they were compensated. The plans encouraged collaboration among stakeholders and expanded environmental protections over 50% of the planned areas while managing industrial growth. Future research on newer plans is needed to fully understand the long-term economic, environmental and social impacts of comprehensive ocean management.

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.
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.
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.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
