Ratan Kumar debnath from the Department of EEE at Daffodil International University presented on the fabrication process of an n-type MOSFET (nMOS). The key steps included growing a thick silicon dioxide layer, depositing and patterning a polysilicon gate using photolithography, diffusing n-type impurities into the substrate to form the source and drain, depositing metal contacts, and patterning the metal layer to connect the transistor components.
The document describes the key steps in the NMOS fabrication process:
1) Photolithography and etching are used to pattern the silicon dioxide and polysilicon layers to define the gate, source, and drain.
2) Doping forms the n-type source and drain regions.
3) Metallization connects the gate, source, and drain to form the NMOS transistor.

This dissertation investigates the dependency of cell mechanics on substrate topography through fabrication of silicon nano-pillars and measurement of elasticity of 3T3 fibroblast cells on the pillars. Different heights and diameters of silicon nano-pillars were fabricated using techniques including block copolymer micelles, photochemical growth of gold nanoparticles, and reactive ion etching. Characterization was done using scanning electron microscopy and elasticity measurements of cells and substrates were performed using atomic force microscopy. Results showed that substrate elasticity increased with larger pillar diameters and heights, while cell stiffness was highest on pillars with the lowest diameter and height. Pillars with the same diameter but different heights showed similar elasticity for cells and substrates. Cells spread well

A Corpus-Based Study Of Modal Verbs In Academic Writing Of English Native Spe...Dustin Pytko
This dissertation examines the use of modal verbs in academic writing by Saudi Arabian advanced English learners and native English speakers. The author compiled a corpus from Saudi MA dissertations and compared it to the British Academic Written English corpus. Frequency analysis found Saudi writers underused most modal verbs compared to native writers, except for should. A functional analysis of the nine most common modal verbs identified typical uses in each corpus. The findings have pedagogical implications for improving Saudi learners' use of modal verbs in academic English.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

How to Fix the Import Error in the Odoo 17Celine George
An import error occurs when a program fails to import a module or library, disrupting its execution. In languages like Python, this issue arises when the specified module cannot be found or accessed, hindering the program's functionality. Resolving import errors is crucial for maintaining smooth software operation and uninterrupted development processes.
