Tool
A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Informally the word is also used to describe a procedure or process with a specific purpose. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools. Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", or "apparatus". History Up until recently, weapons found in digs were the only tools of “early man” that were studied and given importance. Tools are the most important items that the ancient humans used to climb to the top of the food chain; by inventing tools, they were able to accomplish tasks that human bodies could not, such as using a spear or bow and arrow to kill prey, since their teeth were not sharp enough to pierce many animals' skins. Machine tools occasioned a surge in producing new tools in the industrial revolution.

The growth response of coffee (Coffea arabica L) plants to organic manure, inorganic fertilizers and integrated soil fertility management under different irrigation water supply levels
Soil fertility management and water supply are important for successful crop production in all agricultural commodities. The use of inorganic fertilizers has been a significant contributor to increased crop productivity since the green revolution, and has resulted in reduced use of organic nutrient sources that farmers have relied on for centuries (Satyanarayana et al. 2002). The quality of fertilizers, their costs and yield contribution are as variable as their sources. The most common sources of organic manure used in crop production are livestock dung, composted and green crop residues, farmyard matter and organic manure from natural systems and material production systems (Lekasi et al. 2001; Mufwanzala and Dikinya 2010; Satyanarayana et al. 2002). Sustainable agriculture is a production process and farm management system that has positive economic, ecological and social benefits in the short and long term (Kilian et al. 2006).
Time bomb
A time bomb (or timebomb, time-bomb) is a bomb whose detonation is triggered by a timer. The use (or attempted use) of time bombs has been for various purposes including insurance fraud, terrorism, assassination and warfare. Construction[edit] Diagram of a simple time bomb in the form of a pipe bomb A time bomb's timing mechanism may be professionally manufactured, either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. Types[edit] Types of time bombs include: Delay-action bomb (bombs dropped by aircraft with a delay to increase damage/disruption)Improvised explosive device ("home-made" bombs with a delay to allow the person placing the bomb to escape)Limpet mine (attached to enemy ships by naval divers) List of some notable incidents involving time bombs[edit] Time bombs in fiction[edit] Such fictional appearances include: See also[edit] References[edit]

Construction
Building construction is the process of preparing for and forming buildings[1] and building systems.[2] Construction starts with planning, design, and financing and continues until the structure is ready for occupancy. Definitions[edit] Building in this article is used as a noun as "...that which is built; a structure, edifice...".[3] The distinction between a building and a non-building structure is not always clear but is sometimes determined if the structure has walls or by its size or use. The Oxford English Dictionary includes that structure may be used for a large or imposing building. Construction is a very general term meaning the art and science to form material or immaterial objects, systems or organizations,[3] and comes from Latin constructionem (from com- "together" and struere "to pile up") and Old French construction.[4] Construction is used as a verb: the act of building, and a noun: how a building was built, the nature of its structure.

Why is affordable finance so important for coffee producers? - Perfect Daily Grind
Coffee producers around the world have long been faced with a raft of financial challenges. Many of these can be traced back to low or unstable coffee prices, but unfortunately, it is not always as simple as just paying farmers more. The world of finance is complex enough before we consider the fact that coffee is a seasonal crop that requires investment in labour and equipment to harvest and sell. Further still, producers often have to contend with prolonged payment terms, a lack of available collateral, and high interest rates. To learn more about finance and its relationship with coffee production, I spoke to industry experts from across the supply chain. You may also like our article on how overcoming logistical hurdles can strengthen direct trade relationships. The issue: Why do coffee producers often need finance? Like many other agricultural products, coffee is seasonal. This model creates instability. Securing farm-level finance: The obstacles Interest rates Collateral Payment terms
Civil engineering
History of the civil engineering profession[edit] Engineering has been an aspect of life since the beginnings of human existence. The earliest practice of civil engineering may have commenced between 4000 and 2000 BC in Ancient Egypt and Mesopotamia (Ancient Iraq) when humans started to abandon a nomadic existence, creating a need for the construction of shelter. During this time, transportation became increasingly important leading to the development of the wheel and sailing. Until modern times there was no clear distinction between civil engineering and architecture, and the term engineer and architect were mainly geographical variations referring to the same occupation, and often used interchangeably.[7] The construction of pyramids in Egypt (circa 2700–2500 BC) were some of the first instances of large structure constructions. In 1818 the Institution of Civil Engineers was founded in London, and in 1820 the eminent engineer Thomas Telford became its first president.
