includes contents related to introduction about nanotechnology, nano particles, applications in agriculture and horticulture, crop protection applications and case studies
Fruits play a vital role in human nutrition as well as generate high income to the growers. Pre-harvest and post-harvest factors have a great effect on the postharvest quality of fruits. The combination of these factors includes genetic, environmental, cultural practices, irrigation, packaging, pre-cooling, storage, transportations, etc. In this paper, we provide a review of studies on how pre-harvest and post-harvest factors influence the post quality of fruits. The influence of pre-harvest and post-harvest factors can be controlled by various cultural practices, use of certain chemicals and high tech recent management practices.
Use of nanofertilizers on fruit trees contributes effectively to improve the fruit quality and increasing the productivity of trees. It reduces environmental pollution by reducing the amount of fertilizers used, which is positively reflected in the increased economic return of the farmers. When nanofertilizers sprayed at very low concentration on fruit trees, these compounds have had a direct effect by increasing the growth, yield and quality of these fruit crops.
This is a seminar paper presentation by Md. Parvez Kabir, an MS Student, Department of Soil Science of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU) as for the requirement of completing an MS degree.

“Seed priming is a controlled hydration technique in which seeds are soaked in water or low osmotic potential solution to a point where germination related metabolic activities begin in the seeds but radical emergence does not occur.”
Cleaning refers to chlorine washing of the banana fruit for the removal of undesirable material including latex, chemicals, adhering soil particles along with the microorganisms carried by the soil.
Sorting in banana would refer to removal of overripe, injured, bruised, rotten, diseased, infected and cut fruits.
Grading in banana fruit would refer to categorization of fruits based on number & size of fingers in each hand.
Indian agriculture feels the pain of fatigue of green revolution.
In the past 50 years, the fertilizer consumption exponentially increased from 0.5 (1960’s) to 24 million tonnes (2013) that commensurate with four-fold increase in food grain output (254 million tonnes) In order to achieve a target of 300 million tonnes of food grains and to feed the burgeoning population of 1.4 billion in 2025, the country will require 45 million tonnes of nutrients as against a current consumption level of 23 million tonnes. The sustainable agriculture and precision farming both are the urgent issues and hence the suitable agro-technological interventions are essential (e.g., nano and biotechnology) for ensuring the safety and sustainability of relevant production system.
Value Addition of Underutilized Crops Aarti Nimesh
Underutilized crops were once grown more widely or intensively
But are falling into disuse for a variety of agronomic, genetic,
Economic and cultural reasons. Farmers and consumers are using these crops less because they are in some way not competing with other species in the same agricultural environment. The decline of these crops may erode the genetic base and prevent distinctive and valuable traits being used in crop adaptation and improvement.
Global climate change and increasing climatic variability are recently considered a huge concern worldwide due to enormous emissions of greenhouse gases to the atmosphere and its more apparent effect on fruit crops because of its perennial nature. The changed climatic parameters affect the crop physiology, biochemistry, floral biology, biotic stresses like disease-pest incidence, etc., and ultimately resulted to the reduction of yield and quality of fruit crops. So, it is big challenge to the scientists of the world.

Needleless electrospun nanofibers containing microcapsules: a methodology for...IJERA Editor
The present paper investigates the facile production of electrospun polyvinyl alcohol (PVA) nanofibers containing either micro-sized polymer or hybrid capsules, using a needleless electrospinning system. Oilcontaining microcapsules with diameters of around 3 or 10 µm, respectively, were produced via an oil-in-water miniemulsion and mixed with a PVA solution. Appropriate adjustment of electrospinning parameters enabled a controlled assembly of PVA nanofibers into a network containing microcapsules, without damaging their integrity. The PVA nanofibers have diameters in a range of 200-300 nm and showed good homogeneity. The introduction of microcapsules caused an increase in the PVA nanofiber diameters probably due to an increase in the solution viscosity. The production of such self-supported and loaded microcontainers could be of high interest for various applications.

Applications of nanotechnology in food packaging and food safetyDr. IRSHAD A
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 ‘out of food’ applications than those where nanoparticles are directly added to foods.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
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 wasn’t 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.

54. FOOD FORTIFICATION
Fortify processed food with nano-encapsulated
nutrients,
Improves:
Increases nutrient content
Fibre -content,
Appearance and taste,
Fortifying nanoparticles of lycopene in tomato juice,
pasta sauce, and jam (Auweter et. al., 1999).
55. PROBIOTICS
• Live mixtures of bacterial species and can be
incorporated in foods
• Probiotic bacterial preparations could be
delivered to certain parts of the gastro-intestinal
tract where they interact with specific
receptors.
• Acts as de novo vaccines.
56. NANO SENSOR
• Can detect toxins and pathogens in foodstuffs in
• the lab, in the farm, during processing, storage or the shelf
• Advantages:
(a) reduced unit costs
(b) working with sample volumes in the range of nanoliters
(c) shorter analysis times
(d) multi-analyte analysis
(e) safer and environmentally friendly devices

69. WHY NANOPARTICLES POSE NEW
RISKS
• Chemically reactive than larger particles
• Greater access to our bodies than larger particles
• Greater bioavailability and greater bioactivity may
introduce new toxicity risks
• Compromise our immune system response
• Easily dispersible in environment.
70. REGULATION
• Nano food products are already
in market.
• The need for a stringent nano
regulation is felt.
• Formulation of regulations
under the process.
• But there are still no laws.
71. Conclusion
• Incorporation of Ag ions, TiO2 and ZnO has been
successfully carried out for their antimicrobial
property in packaging.
• Nano clay and monmorollite are usually used as
based for packaging.
• Encapsulation with terpene oil was also successful
for quality improvement.
• Commercial food and beverages products based on
nano Fe, nano Se and nanoencapsulation are already
in market.
