Abstract
Nanotechnology is a great innovation that is revolutionizing the agricultural practices. It is a science that works at the nanoscale and provides many beneïŹts. In this review, the fundamental concepts of nanotechnology are clariïŹed, focusing on its primary applications and a health and environment risk assessment especially in livestock production. There is currently a lack of reliable, cost-eïŹective diagnostic tests for early detection of diseases in farmed livestock animals. Biosensing technologies have the potential to address these problems by developing innovative diagnostic tools for the rapid detection of key health threats within the agri-food livestock sector. It also allows for greater product innovation, with the creation of new food ingredients or supplements with nanoencapsulation or nanoemulsions, achieving a slow release of some composites, or perhaps obtaining healthier foods through the improvement of organoleptic properties in the product. Although nanotechnology provides many benefits, but as with all innovations, there are disadvantages and risks associated with its use. The risk assessment must take into account that the biokinetic profile and the toxicity in the target tissues can vary depending on which nanomaterial is being referred. A risk-benefit balance on the use of nanomaterials must be carried out, and in the majority of cases, though many people are open to the advancement, more information regarding the risks is required. Above all, it must be legally regulated to guarantee Agrofood safety in all products that have been manipulated using nanotechnology.

How different atoms can be arranged in a way which decides how strong or weak it would be?
When we modify materials at their atomic and molecular level, some very unusual and useful properties are generated. Since the dimensions of atoms and molecule are in nanometers, this technology is called nanotechnology.
Multiple institutions like Department on Information Technology (DoIT), Defence Research and Development Organisation (DRDO), Council of Scientific and Industrial Research(CSIR) and Department of Biotechnology (DBT) provided the funding to researchers, scholars and projects.
National Centers for Nanofabrication and Nanoelectronics were started in Indian Institute of Science, Bangalore and Indian Institute of Technology, Mumbai.
Nanotechnology has the potential to impact many aspects of food and agricultural systems. Food security, disease treatment delivery methods, new tools for molecular and cellular biology, new materials for pathogen detection, and protection of the environment are examples of the important links of nanotechnology to the science and engineering of agriculture and food systems.

Nano-biotechnology is a promising field of interdisciplinary research. It is a novel scientific approach that involves the use of materials and equipment capable of manipulating physical as well as chemical properties of a substance at molecular levels. Nanoparticles present an extremely gorgeous platform for a diverse range of biological applications. It opens up a wide array of opportunities in various fields like medicine, pharmaceuticals, electronics and agriculture. Nanotechnology is ubiquitous and pervasive. It is an emerging field in all areas of science, engineering and technology. The marriage between nanotechnology and biotechnology yields a new class of nanostructured hybrid patterns that will be very efficient and useful as environmental adsorbents, absorbent materials and adhesion materials in environment.
This are can endeavour to provide and fundamentally streamline the technologies currently used in environmental detection, sensing and remediation. Rapid testing technologies and biosensors related to the control of pests and cross contamination of agriculture and food products will lead to applications of nanotechnology in the near future. These include agricultural productivity enhancement involving nanoporous zeolites for slow release and efficient dosage of water and fertilizer, nanocapsules for herbicide delivery and vector and pest management and nanosensors for pest detection. Most investment is made primarily in developed countries; research advancements provide glimpses of potential applications in agriculture. This overview is concentrated on modern strategies used for the management of water, pesticides, limitations in the use of chemical pesticides and potential of nano-materials in sustainable agriculture management as modern approaches of nano-biotechnology.
The outlook of nano-bioscience in agriculture is vague owing to a lot of grounds, for example, the unconstructive response from people towards genetically modified (GM) crops, need of a lot of required cleverness in government agricultural research and technology units for nano type of explorations and poorly-equipped new instruments and new-fangled technologies. Welcome to Nano World.

Applications of Nanotechnology in Food Packaging and Food Safety (Barrier ma...Dr. IRSHAD A
Â
Over the past few decades the evolution of a number of science disciplines and technologies have revolutionized food and processing sector. Most notable among these are biotechnology, information technology etc⊠and recently nanotechnology which is now constantly growing in the field of food production, processing, packaging, preservation, and development of functional foods. Food packaging is considered as one of the earliest commercial application of nanotechnology in food sector. Around more than 400 Nanopackaging products are available for commercial use. In 2008, nanotechnology demanded over $15 billion in worldwide research and development money (public and private) and employed over 400,000 researchers across the globe (Roco, M. C. et al. 2010). Nanotechnologies are projected to impact at least $3 trillion across the global economy by 2020, and nanotechnology industries worldwide may require at least 6 million workers to support them by the end of the decade (Roco, M. C. et al. 2010). Scientists and industry stakeholders have already identified potential uses of nanotechnology in virtually every segment of the food industry from agriculture (e.g., pesticide, fertilizer or vaccine delivery; animal and plant pathogen detection; and targeted genetic engineering) to food processing (e.g., encapsulation of flavor or odor enhancers; food textural or quality improvement; new gelation or viscosifying agents) to food packaging (e.g., pathogen, gas or abuse sensors; anticounterfeiting devices, UV-protection, and stronger, more impermeable polymer films) to nutrient supplements (e.g., nutraceuticals with higher stability and bioavailability). Undeniably, the most active area of food nanoscience research and development is packaging: the global nano-enabled food and beverage packaging market was 4.13 billion US dollars in 2008 and has been projected to grow to 7.3 billion by 2014, representing an annual growth rate of 11.65% (www.innoresearch.net).This is likely connected to the fact that the public has been shown in some studies to be more willing to embrace nanotechnology in âout of foodâ applications than those where nanoparticles are directly added to foods.
Nano technology for crop resilience to climate change,
this seminar mainly related to crop response to applied nano particles in different environmental stresses like drought ,salt stress,etc,.
The nanotechnology aided applications have the potential to change agricultural production by allowing better management and conservation of inputs of plant and animal production. Several nanotechnology applications for agricultural production for developing countries within next 10 years has been predicted (SalamancaâBuentella et al., 2005).
Nanoparticles helps in Controlling the Plant Diseases, application of agricultural fertilizers, pesticides, antibiotics, and nutrients is typically by spray or drench application to soil or plants, or through feed or injection systems to animals. In this context, nanotechnologies offer a great opportunity to develop new products against pests (Caraglia et al., 2011). Nanoscale devices are envisioned that would have the capability to detect and treat an infection, nutrient deficiency, or other health problem, long before symptoms were evident at the macro-scale. The overall goal of this Nanoparticles is to reduce the number of unnecessary problems in agriculture (Thomas et al., 2011). In the management aspects, efforts are made to increase the efficiency of applied fertilizer with the help of nano clays and zeolites and restoration of soil fertility by releasing fixed nutrients (Dongling Qiao, et al., 2016). Nanoherbicides are being developed to address the problems in perennial weed management and exhausting weed seed bank. Bioanalytical Nanosensors are utilized to detect and quantify minute amounts of contaminants like viruses bacteria, toxins bio-hazardous substances etc. in agriculture and food systems (Tothill EI, 2011).
In this way, nanotechnology can be used as an innovative tool for delivering agrochemicals safely. More research should be done on the potential adverse effects of nanomaterials on human health, crops and the environmental safety. It is a challenge to Government and private sector as they have to ensure the acceptance of Nano foods. For it to flourish, continuous funding and understanding on the part of policy makers and science administrators, along with reasonable expectations, would be crucial for this promising field.

Nanotechnology is the purposeful manipulation of matter on an atomic scale. Materials created in this manner often exhibit unique physical and chemical properties, which have useful applications in various industries. A growing use for some types of engineered nanomaterials is in the area of environmental remediation, termed nanoremediation. While this technique appears to be effective for cleanup, there are still many unanswered questions regarding its long-term impact to environmental quality and human health. No long-term studies exist regarding the potential environmental impact of nanoremediation. While animal studies have shown the potential for adverse health effects, limited data regarding human health are available. The US Environmental Protection Agency is currently adapting existing regulations to cover the use of nanomaterials in remediation, but this approach is limited. Many questions still remain regarding fate and transport, verification of clean-up, and potential occupational and community exposures.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
Â
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasnât one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as âdistorted thinkingâ.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
Â
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesarâs dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empireâs birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empireâs society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

decrease the time required to recharge a battery. The shelf life of a battery
can be increased by using nanomaterials to separate liquids in the battery
from the solid electrodes.
SPACE
Nanotechnology may hold the key to making space flight more practical.
New materials combined with nanosensors and nanorobots could improve
the performance of spaceships, spacesuits, and the equipment used to
explore planets and moons.
24. FUELS
Nanotechnology is being used for:
ï±Making the production of fuels from low grade
raw materials economical.
ï±Increasing the mileage of engines.
ï±Making the production of fuels from normal raw
material more efficient.
25. BETTER AIR qUALITY
There are two major ways in which nanotechnology is
being used to reduce air pollution: catalysts, which are
currently in use and constantly being improved upon;
and nano-structured membranes, which are under
development.
The pollution removal component utilizes a biofiltration
mechanism, in which polluted air is passed through an
organic medium such as compost or wood chips that
contains bacteria.
26. CLEANER wATER
Nanotechnology is being used to develop solutions to three very
different problems in water quality. One challenge is the removal
of industrial pollution, such as cleaning solvent TCE. Another
challenge is the removal of salt and metals from water. The third
challenge concerns the fact that standard filters do not work on
virus cells.
CHEMICAL SENSORS
Nanotechnology can enable sensors to detect very small amounts
of chemical vapors. Various types of detecting elements, such as
carbon nanotubes, zinc oxide nanowires or palladium
nanoparticles can be used in nanotechnology-based sensors.
27. SPORTING GOODS
Nanotechnology is being used for :
ïIncreasing the strength of tennis racquets by adding
nanotubes to the frames which increases control and power
when you hit the ball.
ïReducing the rate at which air leaks from tennis balls so they
keep their bounce longer.
FABRIC
Making composite fabric with nano-sized particles or fibers
allows improvement of fabric properties without a significant
increase in weight, thickness, or stiffness.
