ENGLISH CHAPTER 6 - THIS IS JODY'S FAWN CBSE BOARD CLASS VIIIPooja M
Jody finds the orphaned fawn from the doe that was killed to save his father from a rattlesnake bite. When Jody finds the fawn, it is weak and does not try to run away. Jody gently picks up the fawn and carries it through the thick bushes back to the road. The fawn follows Jody and bleats for him when he sets it down, showing that it now sees Jody as its caretaker. Jody is overjoyed to have found the fawn and cannot wait to bring it home.
Tsunamis are large, powerful waves caused by undersea earthquakes. In 2004, a tsunami hit parts of India and Thailand, killing over 150,000 people. However, many animals seemed to sense the impending disaster and fled to safety, including elephants that screamed and ran inland and zoo animals that rushed into shelters. Some experts believe animals have a sixth sense or can detect vibrations that humans cannot, allowing them to escape danger from natural disasters like tsunamis.
Mechanism of Inhalation and exhalation, Respiration in other animals-cockroach, earthworm, frog, fish , whales and dolphins, respiration in plants, exchange of gases in plants
The document discusses how humans have become indifferent to their essential need for water survival and how other resources have become victims of this indifference as well. It suggests that a public awakening is needed as an eye opener to save water for the future.
07. Weather climate and Adaptations of Animals to Climate by Dilip Kumar ChandraDilip Kumar Chandra
The document discusses climate and weather, as well as animal adaptations to polar and tropical regions. It notes that weather varies daily but climate is the average pattern over long periods. Animals in polar and tropical areas have adapted to survive their extreme climates through traits like thick fur, camouflage, and ability to conserve heat and water. The polar bear, penguin, and monkey are provided as examples and their adaptations described.
The poem "No Men Are Foreign" by James Kirkup promotes the message of unity and harmony among all people regardless of differences. The poet says that no men are strange and no countries foreign, as we are all human beings made of the same flesh and blood. While we may have different customs and beliefs, our basic human emotions are the same. The poem stresses that we should not hate others or consider them enemies. Instead, we should recognize our universal brotherhood as children of God living on the same earth.

A mixture consists of two or more substances that are not chemically combined. There are several methods to separate the components of mixtures.
[1] For solid-solid mixtures, components can be separated by hand picking, threshing, winnowing, sieving, magnetic separation, or sublimation. [2] For solid-liquid mixtures, evaporation or crystallization can be used. [3] Other methods include sedimentation, decantation, loading, and filtration to separate solids from liquids. Immiscible liquids can also be separated since they do not mix.
The document discusses weather, climate, and animal adaptations to different climates. It defines weather as the daily conditions of the atmosphere, including temperature, humidity, and wind speed. Climate is defined as the average weather pattern over about 25 years. Animals in cold polar regions, like polar bears, have thick fur and fat to insulate against freezing temperatures. Animals in hot, wet tropical rainforests, like monkeys and frogs, are adapted to live in trees and have physical features suited to their environment.
Walt Whitman was a revolutionary American poet who wrote in free verse, breaking from traditional rhyming poetry. This poem expresses the writer's view that animals are more placid and self-sufficient than humans. Animals do not worry over their condition or sins, discuss religion, desire wealth or status, or feel beholden to past generations. In contrast, the writer implies humans are dissatisfied and unhappy. At the end, the writer notes animals seem to represent memories of his childhood in a sarcastic comment on how humans have lost their simplicity.
Kathleen Shirley Toulson was an English poet born in 1924 who wrote this poem viewing an old photograph of her mother from childhood. The photograph shows the poet's mother as a young girl paddling at the beach with her two cousins, all smiling at their uncle taking the picture. Many years later after the poet's mother had passed away, she would still laugh remembering that day at the beach with her cousins. For the poet, the loss of her mother's laughter and presence through her death has left her with nothing more to say about the circumstance other than silence.

The poem "A Tiger in the Zoo" by Leslie Norris describes the sadness and anger of a tiger kept in confinement in a small zoo cage. The tiger would normally be stalking and hunting in the jungle, but is instead restricted to taking only a few steps in its concrete enclosure. The poem contrasts the tiger's natural habitat and behaviors with the miserable reality of its imprisoned life, ignored by visitors yet unable to sleep due to noise at night. Through the tiger's experience, the poem comments on the cruel practice of keeping wild animals captive for human amusement.
This document discusses various methods for separating mixtures into their pure components. It defines homogeneous and heterogeneous mixtures and explains several techniques including evaporation, centrifugation, distillation, chromatography, and fractional distillation. As an example, it explains how fractional distillation is used to separate gasoline and spirits by taking advantage of differences in boiling points between components.
The poet traveled a long hundred miles to the mythical land of Lyonnesse in winter. No one could predict what experiences he would have there. When he returned, his eyes shone with a rare happiness and magic that others silently noticed, as if he had gained a profound revelation during his journey.

Water pollution occurs when harmful chemicals, physical materials, or biological materials are discharged into water sources such as lakes, rivers, oceans, and underground reservoirs. When humans drink polluted water it can seriously impact their health. There are several types of water pollution including surface water, ground water, microbiological, chemical, oxygen depleting, nutrients, and suspended matter. Water pollution is caused by factors such as marine dumping, oil pollution, global warming, and radioactive waste. We can help prevent water pollution by properly applying fertilizers, choosing alternative methods, not littering, following laws, and acting smartly.
This document provides information about a presentation on the poem "On Killing a Tree" by Gieve Patel. It includes biographical information about the poet, an overview of the poem's themes about how deeply rooted evil is and how difficult it is to uproot, and summaries of each stanza describing the lengthy process required to fully kill a tree by extracting its roots from the ground. The presentation was given by Sanjay Dange, a teacher from Jawahar Navodaya Vidyalaya.

1. The document discusses various methods of separating mixtures into pure substances, including handpicking, sieving, magnetic separation, sedimentation, decantation, filtration, evaporation, distillation, and churning.
2. Separation methods work by exploiting differences in properties like particle size, density, melting/boiling points between components of a mixture. Magnetic separation separates out iron filings. Sieving and winnowing separate components by size.
3. Specific techniques are used to separate insoluble solids from liquids, including sedimentation, decantation, coagulation/loading, and filtration. Distillation separates components by selective boiling and condensation.
The poem describes how to identify different wild animals found in jungles through their unique features and behaviors. It discusses Asian Lions, Bengal Tigers, Leopards, Bears, Hyenas and Crocodiles. Each animal is introduced through vivid descriptions and warnings about their dangerous nature. For example, it notes that if an Asian Lion roars at you as you're dying, you'll know it attacked you. Similarly, it explains that Bengal Tigers can be identified by their black stripes on a yellow ground and may eat you if they greet you.
Earthquakes are caused by slow movements within the Earth as it continues to cool. Some human activities like constructing dams, extracting groundwater, fracking, and building skyscrapers can also induce earthquakes by adding stress that destabilizes existing faults. Earthquakes have both primary effects of immediate damage through collapsing buildings, and secondary effects like tsunamis, landslides, fires, disease outbreaks, and soil liquefaction that prolong suffering after the initial quake.
Well this is my first presentation in the slide share. In this presentation i have mentioned about the concept of water quality and guidelines for it in with the perspective to human health and its management in Nepal.

An earthquake of magnitude 7.8 struck Nepal on April 25, 2015. The earthquake caused widespread damage, killing over 8,800 people. It destroyed buildings and infrastructure across the Kathmandu valley. The earthquake also triggered landslides that killed people climbing Mount Everest. India launched a major rescue and relief operation called Operation Maitri to help Nepal in the aftermath of the devastating earthquake.
Rabindranath Tagore was a renowned Bengali poet, musician, and artist who won the 1913 Nobel Prize in Literature. The poem "The Last Bargain" describes the poet seeking employment from different people but finding their offers lacking until a child offers to hire him with nothing, making him a free man. In four stanzas, the king offers to hire the poet with power, a rich man with money, a fair maid with a smile, but it is a child playing on the beach who recognizes the poet and hires him with nothing, granting him true freedom.

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.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

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.
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.
