organism answers it. This approach must lead to a tripartite classification on nervous functions: reception through the senses, reaction from the muscles and glands, and a conduction and integration system that mediates between these two functions. Stimulus excites receptors, specialized structures capable of translating some physical energy into a nervous impulse. Once a receptor is stimulated, the excitation is conducted farther into the nervous system. Bundles of nerve fibers that conduct excitation toward the brain or spinal cord are called afferent nerves. These fibers transmit their message still farther; in the simplest case, to other fibers that go directly to the effectors, the muscles and glands that are the organs of action. Nerve fibers that lead to the effectors are called efferent nerves. The transmission path from receptors to effectors is usually more circuitous than this. The afferent fibers often bring their messages to intermediate nerve cells, or

cotton gin revolutionized the way cotton was harvested and reinvigorated slavery. While in the North, the adoption of interchangeable parts revolutionized the manufacturing industry, and in time contributed greatly to their victory in the Civil War.[3] He died on January 8 , 1825 at the age of 59 The cotton gin is a mechanical device which removes the seeds from cotton, and it had been extremely labor-intensive. The cotton gin was a wooden drum stuck with hooks, which pulled the cotton fibers through a mesh. The cotton seeds would not fit through the mesh and fell outside. Whitney occasionally told a story where he was pondering an improved method of seeding the cotton and he was inspired by observing a cat attempting to pull a chicken through a fence, and could only pull through some of the feathers. A single cotton gin could generate up to fifty-five pounds of cleaned cotton daily. The introduction of Cotton Gins to plantations increased productivity because more slaves could

VORMISTAMISE ÜLESANNE 2 TUNNITÖÖ Õppeaines: SISSEJUHATUS ERIALASSE Tehnoloogia ja ringmajanduse instituut Õpperühm: Juhendaja: Tallinn 2021 SISUKORD 2 ABSTRACT Pilling is an undesired defect of textile fabrics, consisting of a surface characterized by a number of roughly spherical masses made of entangled fibers. Mainly caused by the abrasion of fabric surface occurring during washing and wearing of fabrics, this defect needs to be accurately controlled and measured by companies working in the textile industry. Pilling measurement is traditionally performed using manual procedures involving visual control of fabric surface by human experts. Since the early nineties, great efforts in developing automatic and non-intrusive methods for pilling

Tegemist on ülipeene, peamiselt süsiniku kiududest koosneva materjaliga: mitmed tuhanded süsiniku kiud põimitakse omavahel kokku, moodustades lõnga. Järeltöötluses valmistatakse süsiniklõngast kangaid, mis epoksiidvaikudega segades võimaldavad modelleerida kõikvõimalikke ülitugevaid ning kergeid tooteid. Peamiselt saadakse süsinikkiudu PAN-kiu kuumutamisel õhus 220 C juures, seejärel kuumutamisel inertses atmosfääris 1000C juures ja lõpuks grafitiseermisel 2000 C juures.

, these specs do not affect you. Fiber Itself Fiber Optics, as we said, is sending signals down hair-thin strands of glass or plastic fiber. The light is "guided" down the center of the fiber called the "core". The core is surrounded by a optical material called the "cladding" that traps the light in the core using an optical technique called "total internal reflection." The core and cladding are usually made of ultra-pure glass, although some fibers are all plastic or a glass core and plastic cladding. The fiber is coated with a protective plastic covering called the "primary buffer coating" that protects it from moisture and other damage. More protection is provided by the "cable" which has the fibers and strength members inside an outer covering called a "jacket". Multimode & Singlemode Fibers Multimode & Singlemode fiber are the two types of fiber in common use. Both fibers are 125 microns in outside

According to Cohen & Lee (1988) Supply Chain Management is "The network of organizations that are having linkages, both upstream and downstream, in different processes and activities that produces and delivers the value in form of products and services in the hands of ultimate consumer." Thus a shirt manufacturer is a part of supply chain that extends up stream through the weaves of fabrics to the spinners and the manufacturers of fibers, and down stream through distributions and retailers to the final consumer. Though each of these organizations are dependent on each other yet traditionally do not closely cooperate with each other. An integrated supply chain management streamlines processes and increases profitability by delivering the right product to the right place, at the right time, and at the lowest possible cost.

Coal is used to generate almost half of all electricity produced in the United States. Besides electric utility companies, industries and businesses with their own power plants use coal to generate electricity. Power plants burn coal to make steam. The steam turns turbines which generate electricity. 15.4.2 For industry A variety of industries use coal's heat and by-products. Separated ingredients of coal (such as methanol and ethylene) are used in making plastics, tar, synthetic fibers, fertilizers, and medicines. The concrete and paper industries also burn large amounts of coal. 15.4.3 For making steel Coal is baked in hot furnaces to make coke, which is used to smelt iron ore into iron needed for making steel. It is the very high temperatures created from the use of coke that gives steel the strength and flexibility for products such as bridges, buildings, and automobiles. 54 15.4.4 For export In 2006, 49

Belarusians are employed by state-controlled companies, while others are employed mainly by private Belarusian companies, and less than 2% of Belarusians are employed by foreign companies. Export / Import Belarusian economy is dominated by services as well as industrial production. The majority of Belarus trade is dominated by products such as tractors, trucks, motorcycles, televisions, metal-cutting machine tools, earthmovers, fertilizer, textiles, radios, refrigerators and synthetic fibers. In its imports and exports, Belarus depends on Russia, which is its major trade partner. Russia accounts for 45% of Belarusian foreign trade turnover, followed by the European Union, the second largest trade partner of Belarus. At the end of 2011, Russia accounted for 34% of the exports and 54.5% of the imports of Belarus, while the European Union accounted for 39% and 19%, respectively. Statistics show that exports to non-CIS countries have considerably increased recently.

fluid. These miracles of the test tube, called F and P inks by the I British chemists who taught the Americans much of what they knew, were so precisely formulated that they would react with only one other chemical to form a visible compound. Eventually, the Allied chemists discovered a reagent that brought out secret writing in any kind of ink, even clear water. Crystals of iodine, heated gently, sublimated into fumes of a beautiful violet hue that settled more densely in those fibers of paper that had been disturbed by any kind of wetting action, thus tracing the pen's course. The Germans replied by writing in a sympathetic ink and then moistening the entire sheet. The Allies struck back with a chemical streak test that would show whether the paper surface had been dampened. This was almost as incriminating as actual development of a secret-ink letter, for who but a spy would wet a letter? The seesaw battle between the chemists of
