Various implant systems in india final
The document discusses various dental implant systems used in India, including their designs, materials, and indications. It summarizes the Branemark system, which introduced the term osseointegration. It also describes the Replace Select Tapered system, Frialit system, ITI system, Core Vent system, Integral system, and Pitt-Easy system - outlining their key features such as diameters, lengths, surfaces, advantages, and common uses. The document provides an overview of important implant systems and their characteristics.
Implant materials
This document provides an overview of the history and classification of dental implants. It discusses the various types of implants including endosteal, subperiosteal, and transosteal implants. The key implant materials discussed are metals like titanium alloys, cobalt-chromium alloys, and stainless steel, as well as ceramics and polymers. Titanium and its alloys are highlighted as the most commonly used and biocompatible implant materials. The document also reviews factors involved in selecting implant materials and ensuring clinical success.
Implant surface modifications
Dental implants can be modified at the macro, micro, and nano levels to improve osseointegration and healing times. At the macro level, implant thread design is modified. Micro level modifications alter the surface topography through processes like sandblasting and acid etching. Nano level modifications increase the surface area through additions like titanium nanotubes. Coatings of hydroxyapatite and other calcium phosphates are also used at the micro and nano scales to promote bioactivity. Surface modifications generally increase roughness and research shows rougher surfaces correlate with higher success rates.
Smart Composites -Review.pptx
This document discusses different types of smart composites. It defines smart composites as materials composed of smart materials embedded in polymers, metals, or concrete to sense, control, and communicate. Smart materials can change properties in response to stimuli like temperature, pressure, or electric fields. Some examples of smart materials given are piezoelectric, shape memory, and pH sensitive polymers. The document then describes four general classifications of smart composites: 1) structural composites for sensing damage, 2) composites for actuation using shape memory materials, 3) novel functional composites like self-healing, and 4) nanocomposites enabling new functions.

Engineering bone tissue using human Embryonic Stem Cells
Bone defects lead by traumatic injuries, congenital malformations and other surgical rescissions rises the immediate need for a more evolved and safer approaches in tissue repair at alarming rates for the downgrading issues with existing strategies which needs to be addressed. Currently practiced treatment methods addressing the issue with bone defects are invasive, traumatic and are not cost effective. Yet, issues of immune rejection either immediately or in the later stages have been reported claiming its ineffectiveness in some selective case studies.
Previous work by researchers carried out the "Biomimetic" approach to provide the cells with the microenvironment and in situ conditions for the cells seeded into the 3D Osteogenic scaffolds enriched with growth supplments. Here, we address the issue of non-availability of therapeutic cells - a major problem with current translational medicine by proposing the use of Human Embryonic Stem Cells in generating strong and structurally rigid bone tissue. Inducing the production of Mesenchymal Progenitor cells from Human Embryonic Stem cells in Serum supplemented expansion medium and elimination of bone Fibroblast growth factor produced high quality MPCs which were induced in osteogenic medium to result in bone differentiating cells. Culturing these MPCs produced from three different protocols into 3D Scaffold and 3D-Endoret Osteogenic Scaffold produced tissue constructs which are analysed both biochemically and Histologically to check for the Bone tissue differentiation parameters such as Bone sialoprotein deposition, Osteopontin accumulation and Collagen deposition. Matrix mineralization in these constructs were studied by uCT imaging and safety studies were conducted by studying Orthotopic implantation models in SCID mouse. And the results are expected to be optimistically affirmative which shall lay a new foundation and pioneer a whole new approach in the field of Tissue Engineering.

GREEN COMPOSITES
Green composites are sustainable composite materials made from bio-polymers or polymers reinforced with bio-fibers to create strong, lightweight materials with natural resources. The main advantages of green composites are that they are recyclable and biodegradable. Polymer matrix composites consist of thermoset, thermoplastic, or elastomer matrices mixed with fibrous reinforcements. Fiber-reinforced polymer composites are used because they have low cost, are biodegradable, have good mechanical and thermal insulating properties. Wood plastic composites are an important green composite that provides durability without toxic elements by combining plant fibers with polymers.

Glaciers (teach)
Glaciers form when more snow accumulates each year than melts, compressing into thick sheets of ice that slowly flow downhill due to their mass. There are two types of glaciers: continental glaciers that form over large areas near poles, and mountain glaciers that form near mountaintops. Glaciers shape landscapes through erosion, gouging out valleys and depositing debris in moraines as they recede.
What are glaciers?
A glacier forms over many years in places where snow falls but does not melt, accumulating in layers that compress into ice. As glaciers move into warmer areas, melting occurs at the glacier's snout or front. Glaciers advance when accumulation exceeds melting and retreat when melting exceeds accumulation. Factors influencing this balance include climate cycles, volcanic eruptions, and human-caused global warming, which is currently causing many glaciers to retreat rapidly.

Anne Claire Science Powerepoint Final!
Glaciers erode and shape the landscape by picking up rocks, dirt, and other debris as they move. Most of the world's largest glaciers are located in Alaska, where the Hubbard Glacier is the largest tidewater glacier in North America. Glaciers help provide fresh water for drinking and irrigation, but storing over 70% of the Earth's fresh water, melting glaciers threaten to raise sea levels by up to 80 meters if climate change is not addressed.
What is a glacier

Intro To Glaciation
The document discusses how glaciers and ice ages are connected to the UK. During the last ice age, huge ice sheets covered much of the UK, with ice being up to 2 miles deep. The landscape of Britain was shaped by the erosion of these ice sheets as they advanced and retreated over thousands of years. We may currently be in an interglacial period within the ongoing ice age. Factors that can influence ice ages include changes in atmospheric and ocean circulation as well as decreases in the sun's energy reaching the Earth.
Glaciers and Glaciation
Glaciers are large, slow-moving masses of ice that form from compacted snow. They are found in mountain ranges and polar regions. Glaciers are sensitive to climate conditions and influence sea levels and water resources. They are categorized based on their thermal characteristics, behavior, and location. Alpine glaciers are confined to valleys while continental glaciers span entire regions. As glaciers accumulate more snow than melts, they grow, but melting exceeds accumulation in warmer periods, causing glaciers to recede.
RIVER OF ICE
1. A glacier is a large, long-lasting mass of ice formed on land that masses downhill under its way.
Glacier is part of the earth’s hydrosphere.
Along with the sea, ice glaciers are known as the cryosphere.
2. GROUP OF GLACIER:
They fall into two general groups based on their form size and flow characteristics
3. Alphin glacier that is surrounded by mountains is called an alpine or mountain glacier.
Glaciated valleys are through like U-shaped with board floors and relatively smooth, and steep sides
The valleys may contain littered debris or debris shaped as moraines with a swampy appearance.
There may be taken gouged out of the rocky floor or formed by debris within the valley.
Cirque Glacier: Bowl-like hollow structures are called cirque glaciers. They are formed inside the mountains and tend to move towards the valley. A glacier that forms in a cirque is a cirque glacier. Piedmont Glacier: When the steep valley glaciers spill into flat plains, then a piedmont glacier occurs e.g Malaspina glacier that falls into Yakutat Bay, Alaska. Hanging glacier: When the major valley glacier thins out, that becomes a hanging glacier. Tidewater glaciers: These are valley glaciers that reach the sea, and they provide breeding habitat for seals. These glaciers are the ones that form small icebergs.
4. Continental glaciers are those vast masses of ice sheets covering stretches of land. Such glaciers flow over large areas that are unconfined, where they bury the landscapes underneath
Today, continental glaciers are only present in extreme polar regions: Antarctica and Greenland Historically, continental glaciers also covered large regions of Canada Europe and Asia, and they are responsible for many distinctive topographic features in these regions.
The ice sheet blankets 81% of Greenland and 90% of Antarctica.
FORMATION AND FLOW:
IMPORTANCE OF CONTINENTAL GLACIER:
Glaciers are an essential indicator of the study of environmental change, thereby making people aware of the increasing global warming. Due to the continuously growing industrialization, and use of automobiles, there is a rising graph of air pollution triggered by the emission of carbon monoxide and other harmful greenhouse gases. The outcome of all these is the catastrophic increase in global warming and greenhouse gases.
Glaciers come in a huge range of shapes and sizes. Different glaciers, and even different parts of the same glacier, can have a variety of different thermal, hydrological and dynamic characteristics. Glaciers occur in locations ranging from the poles to the equator, and most parts of the world have experienced the direct effects of glaciation at some time in the past. Glaciers currently occupy less of the planet than they have done in geological history, but nevertheless exert a profound influence on the global environment. Our developing understanding of glaciers will play an important role in our understanding of the global environmental system
Imja Lake clip book
The author describes a two-day hike from Lukla airport to Namche Bazaar in Nepal as part of a Mountain Institute expedition. The hike highlights the difficulties developing countries like Nepal face in addressing climate change due to their remoteness and poverty. Reaching field sites to monitor glaciers and conduct research is challenging given the need to travel on foot and rely on human porters to transport equipment over rugged terrain.
The Antarctic Ice System
The document discusses different types of ice found in Antarctica and their importance:
1. Sea ice forms annually on the ocean surface around Antarctica and plays a key role in global ocean circulation and cooling.
2. Ice shelves are thick floating sections of ice that flow slowly off the land into the ocean. They act as barriers to slow the flow of continental ice sheets into the ocean.
3. Ice sheets cover over 98% of the continent and have accumulated over millions of years. Their high reflectivity helps cool the planet. Loss of ice from warming is concerning as it could lead to sea level rise.

This topic is all about Glaciation. This includes; the causes of glaciation, the origin of glaciers, formation, primary types, movement, the erosional, transportation and depositional mechanisms. This also includes the common landforms brought by glaciers.
Glacier presentation
Glaciers are large, thick masses of ice formed from compacted snow that move very slowly due to their sheer mass. They are primarily located in polar and mountainous regions. Glaciers shape the surrounding landscape through erosion and can carve out dramatic valleys and mountains over thousands of years. However, glaciers have been retreating rapidly in recent decades due to global warming, which poses risks like flooding and affects global sea levels, ocean currents, climate patterns, wildlife, and more. The only way to slow glacial melt is to reduce greenhouse gas emissions that cause unnatural climate change.
Glaciers
1. Glaciers are thick masses of ice that slowly flow downhill under their own weight. They help shape landscapes through erosion and deposition. The two main types are valley glaciers and ice sheets. Greenland and Antarctica have massive ice sheets.
2. Glaciers move via plastic flow and basal sliding. They accumulate ice in the accumulation zone and lose ice in the ablation zone, through melting and calving of icebergs.
3. Glaciers erode bedrock through plucking and abrasion, grinding rock into fine flour-like sediment.
Glacial ice powerpoint
Glacial ice is the largest reservoir of freshwater on Earth and supports one third of the world's population. Glaciers form on land where snow accumulation exceeds melting. They slowly deform and flow due to their own weight, creating features like crevasses. Glaciers erode the underlying landscape through abrasion and plucking of rock debris. As they carry this debris and later melt, glaciers leave behind landforms such as moraines, eskers, and drumlins that provide evidence of past glacial activity. Glacial periods within ice ages are marked by colder temperatures and advancing glaciers, while interglacials are warmer intervals between them.
Glaciers and its types
This document provides an overview of glaciers, including their formation, movement, and important terminology. It describes the key parts of a glacier, including the accumulation and ablation zones. The document also discusses different types of glaciers and their varying speeds of movement. Finally, it covers the erosional and depositional landforms created by glaciers, such as moraines, eskers, and drumlins.
Glaciers project
Glaciers are large masses of ice formed from compacted snow. They form in locations where snowfall exceeds melting over many years, such as mountainous and polar regions. Glaciers are sensitive to temperature changes and have been retreating at unprecedented rates since the early 20th century due to climate change caused by human activity like the Industrial Revolution. As glaciers melt, it impacts fresh water supplies and hydroelectric power generation. Potential solutions to reduce melting include lowering emissions and improving carbon sequestration through soil and underground storage.
Glaciers
Glaciers are large, thick masses of ice formed from compacted snow that accumulates over many years. Glaciers form in areas where snow accumulation exceeds melting. Due to their great mass, glaciers slowly flow downhill like rivers. Glaciers erode the underlying landscape and form characteristic landforms as they advance and retreat. Melting glaciers provide fresh water for many communities but are now threatened by global warming.

The document discusses glaciers and glaciation. It describes how glaciers form from compacted snow and flow over land under their own weight. Glaciers cover around 10% of Earth's surface today, occurring in places like Greenland, Antarctica, and mountain ranges. The document outlines different types of glaciers and how glaciers can erode landforms through processes like plucking, abrasion, and bulldozing. Glaciers can deposit sediments in the form of till, outwash, moraines, kames, eskers, and other landforms as they melt. The cyclic advance and retreat of ice sheets over geological time, including multiple glacial and interglacial periods in the Pleistocene
Pakistani and world glacier a review Akbar Hussain
Glaciers around the world and in Pakistan are melting at an accelerated rate due to global warming. In Pakistan, glaciers are a major source of water and are critical for agriculture, yet they are receding rapidly which will lead to water shortages in the coming decades. The document discusses evidence of melting glaciers in different regions of the world as well as key glaciers in Pakistan's Himalayan and Karakoram ranges that feed major rivers and are vital for irrigation and fresh water supplies.

A.为什么留学生需要操作留信认证?
留信认证全称全国留学生信息服务网认证,隶属于北京中科院。①留信认证门槛条件更低,费用更美丽,并且包过,完单周期短,效率高②留信认证虽然不能去国企,但是一般的公司都没有问题,因为国内很多公司连基本的留学生学历认证都不了解。这对于留学生来说,这就比自己光拿一个证书更有说服力,因为留学学历可以在留信网站上进行查询!
B.为什么我们提供的毕业证成绩单具有使用价值？
查询留服认证是国内鉴别留学生海外学历的唯一途径但认证只是个体行为不是所有留学生都操作所以没有办理认证的留学生的学历在国内也是查询不到的他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单就有了使用价值。乌龟和王八贼头贼脑的倒也逗人喜爱日上三竿时山娃总爱窜进自家瓜棚里跟小伙伴们坐着聊天聊着聊着便忍不住往瓜田里逡巡一番抱起一只硕大的西瓜用石刀劈开抑或用拳头砸开每人抱起一大块就啃啃得满嘴满脸猴屁股般的红艳大家一个劲地指着对方吃吃地笑瓜裂得古怪奇形怪状却丝毫不影响瓜味甜丝丝的满嘴生津遍地都是瓜横七竖八的活像掷满了一地的大石块摘走二三只爷爷是断然发现不了的即便发现爷爷也不恼反而教山娃辨认孰熟孰嫩孰甜孰淡水
