This document provides an overview of OSHA's new fall protection standard for general industry workplaces. Some key points:
- The standard clarifies that fall protection is required for unprotected sides or edges that are 4 feet or more above a lower level, unlike the construction standard of 6 feet.
- It defines terms like hole, designated area, and provides requirements for fall protection methods including guardrails, safety nets, personal fall arrest systems, and ladder safety systems.
- Training requirements are specified, requiring employees be trained on fall hazards, fall protection procedures and equipment by a qualified person.

Martin Cox - Directional Drilling - technology, development and achievements ...MiningInstitute
Presented to the North of England Institute of Mining and Mechanical Engineers (8 Dec 2016).
At the end of the 19th Century oil well drilling was a slow process, based on a variety of mining based innovations, combined and adapted to access simple, close to surface reserves. The Spindletop discovery, Beaumont Texas 1901, utilised the rotary drilling process to access a reservoir at +/- 1,000ft, and the Texas Oil Boom soon made the USA the world's leading oil producer.
As the demand for oil and gas increased, the industry faced increasing challenges, the drilling process has required major advances to meet demand and keep the industry competitive. The development of directional drilling technology has had a major impact on the industry’s ability to access smaller, more complex reserves with increasing environmental constraint. Accessing unconventional reserves such as geothermal energy and carbon capture developments will require its use.
Martin Cox began in 1979 as an NCB Student Apprentice in the South Nottinghamshire Area. Graduating in Mining Engineering he joined the offshore oil industry. His 30 years in well engineering activities, overseas & the UK, includes commercialisation and development of directional drilling & related technologies in use today. Now with Aberdeen Drilling Management (ADM) engaged in investment, application of
expertise and technology, with a view to future energy requirements and environmental challenges. Martin is President elect for the Institute IOM3 2017/18.

Mechanical contractor lockout confined space awareness ppt 2021John Newquist
This month’s powerpoint is a custom one that I did for a large mechanical contractor. They wanted all employees to learn some lockout and confined space. The workers that would enter a confined space or lockout would take a four hour version. Custom training is the growing area of safety. They said the past lockout was only for machines that they would never lockout.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
