...been a few injuries, chronic fatigue and potential burnout. I decided to step back this year while training for the marathon by preventing myself in falling in the same pattern again. Often times, the best barometer of feedback is not in watts, heart data or fancy graphs. Some of the best feedback comes from our gut instincts. Finding the joy in training and being opening up to being more flexible in our regimen is just as important as all the hard interval work or getting in the volume. This said, I decided to listen to my inner voice which said, “I think I need to rest more today.” That inner voice often sent me an SOS signal calling for either a brief physical or mental break. The best advice that I can give to you as a runner is to speak to yourself as if you were your own best friend. What would you say to a good friend if she or he felt pressure to so something on plan, but knew deep inside what they really needed? What would you say to your friend if he or she said that she was really, really tired and not up for doing something you had planned together? You’d probably say that “it’s okay – we’ll get it in another time.” The best runners, who perform well consistently, often follow a structured training plan. However, they also have learned the art of listening to that inner voice and allowed for flexibility within their plan. As a runner, you need to understand and trust that it’s OK to back off. Listening to that inner voice and allowing for that flexibility...

...Copper is the most used cabling solution in the market at the moment due to its ease of use and its price. Even the equipment is substantially cheaper to buy than other means of transmission. Copper cabling utilizes a single or multiple strands of copper to transmit data from one end to the other. Copper is broken up amongst several different categories each with their own set of improvements and flaws ranging from difficulty of installation to cost. The lower the category the more prone to interference there is like EMI’s and RFI’s. Electromagnetic interference from other cables in the location like power cords or other data connections. And RFI Radio frequency spectrum interference although the higher categories like Cat 7 are less prone to such interference a coper cabling solution is not 100 percent protected from such external interferences. Copper does have some limitations in how long a data signal can be sent without it becoming lost or the signal becoming too weak to make a proper connection which is around the 1000 feet or 305 meter range. Fiber optic on the other hand is much more expensive and as such so are the tools used for installation. Fiber optic is compiled of a core which can resemble glass in its form and a laser or diode that emits a light from one end to another enabling data transmission. Fiber is the best solution in speed and range that data can be transmitted. There are two different types of fiber optic cabling one being multi-mode and the other being single-mode...

...CHAPTER 1 INTRODUCTION 1.1 Problem Definition The rated power generated from the engine of a heavy duty vehicle can only become useful when effectively transmitted from the engine via the fly wheel to the transmission system of the truck and finally to the final drive. The propeller shaft or the drive shaft which is the mechanical component used for transmitting torque and rotation is used in transmitting these generated power to the final drive. However, when the Ghana Armed Forces introduced the Chinese made Dong Feng trucks which are five ton troop carrying vehicles (TCVs) for its operations, their propeller shafts recorded a high rate of failure. This inevitably affected the morale of troops and the operations of the Ghana Armed Forces. Some drivers of the truck fearing the propeller shaft failure could result in accident, hanged nylon rope or chain under the trucks to prevent a failed shaft from striking the ground. Below are pictures to that effect. This project therefore aims at identifying the causes of the failures of propeller shafts and recommend mitigating measures to them. Fig. 1.1 Nylon Rope Beneath the Propeller Shaft 1.2 Objectives The objectives of this project work are: * To identify the causes of propeller shaft failure of heavy duty trucks at the Base Workshop. * To recommend mitigating and preventive measures to the problems. 1.3 Justification It is anticipated that the findings of this project will...

...The differential was first invented in China, in the third century,A.D. After turning a car the outside wheel has to turn faster then the inside one in order to cover the greater distance. That is why two wheels are not driven at a same speed. So we need a differential gear. A car differential is a place halfway between the wheels, on either the front or both axes. Main mechanisms: Wheels receive power from the motor via drive shaft. The power receiving wheels which makes the vehicle move fowrord are called as the drive wheels. Wheels receive power from the motor via drive shaft. The main function of the differential gear is to allow the drive wheels to turn at different Rpm while from the engine. The main characterics of differential is to, * To aim the engine power at wheels. * To transmit the power to the wheels while allowing them to rotate at differential speeds. the left wheel has to travel more distance compared to the right wheel. If the wheels where connected using a soil shaft. The wheels where connected using a soil shaft. The wheels would have to slip to accomplish the turn. The mechanism in a differential allows left and right wheels to turn at different Rpm, while transferring power to both the wheels. Differential parts: There are three types of gear available, Pinion drive gear: Transfers power from the drive shaft to the ring gear. Ring gear: Transfers power to the differential case assembly Side/Spider gears: Helps both wheels to turn...

...complex and interesting part of any vehicle. A car can be broken down into three major mechanical components; the internal combustion engine which is the vehicles power source, the transmission which is its gearing system, and the rear differential axle which applies the power to the road. The internal combustion engine is the cars main power source. The engine is a series of pistons and rods housed inside an engine block. The engines pistons and rods are then rotated by a crankshaft at a high rate of speed through the power of internal combustion. Gasoline is then injected into an intake, where it blends with just the right amount of air to combust upon contact with a spark produced by a spark plug. This explosion then pushes the piston down, which in turn pushes another piston attached to the crankshaft back up. The rotating crankshaft then spins a flywheel attached to it, which transfers the power to the transmission. A transmission is a cars gearing system. It uses a sequence of gears to control the engines speed and revolutions. All engine have a red line, a maximum rpm value above which the engine cannot go without exploding. Depending on the engine the values may vary up or down. Different engines will have different power bands where the power is designed to be. The job of any transmission is to allow the driver to use these bands by shifting to designated gearing ratios to the engines full gearing potential. As the flywheel spins, it is engaged by a...

Jayanthi Sriram, Asst.Director) GOVERNMENT OF INDIA INSTITUTE SECRETARIAT TRAINING & MANAGEMENT DEPARTMENT OF PERSONNEL & TRAINING ADMINISTRATIVE BLOCK, JNU CAMPUS (OLD) OLOF PALMS MARG, NEW DELHI-110067 TEL. 26105592 TELEFAX: 26104183 Revised - 2005 FORWARD In responsive administration it is obvious that the response has to be meaningful. Yet, it may not be effective unless the response time is optimised. This twin objective can be achieved through streamlining of the decision making process itself. In the Central Secretariat, as in other spheres of Government, contribution by all rungs of employees particularly by those at the cutting edge level, namely the Section Officers and Assistants, generally helps arriving at the right decision. Besides collection of information, such contributions are rendered through Noting & Drafting. Effective noting & drafting at every level, therefore, is a matter of prime concern. 2. To address this concern, we in ISTM have been according utmost importance to the inclusion of 'noting and drafting' as a subject in all our foundational and refresher Courses. Besides, focussed workshops on effective noting & drafting are also organised in large numbers. To help participants team effectively, the need for practical exercises cannot be overemphasised.

...had been working with Flanagan for just over a month. She knew she had to kill the DailyDilly initiative but was reluctant to do it with the reps present. “Let’s discuss this off-line,” she said. Will slapped the table. “Come on,” he demanded. “We’re here now.” The DailyDilly reps became wide-eyed. Allie took a deep breath. If Will was going to push her, she’d be blunt. “No, then,” Allie said. “It’s not on.” Will pushed his chair back and walked out of the room. The reps started to review their presentation, but Allie stopped them with a wave of her hand. Ruth, no longer smiling, told them all she was sorry and stood up to escort everyone out. Allie knew she had just made some enemies. Half an hour later, Ruth stopped her in the corridor. “So you’re still not convinced?” “Roddy asked me to weigh in on DailyDilly for a reason,” Allie said.

...aroma. "So where did you meet?" I asked my friend Patrick as he put down his coffee cup. "In the Faculty Center in UP." "Again? How come you meet a lot of guys there? I'm always there and nothing ever happens." Patrick pointed to his face and smiled. "Che!" I replied laughing. But I knew that it was true. Patrick was not really that good looking, but he had this sexy air about him. And he had fair skin which is, for most Filipinos, a prerequisite for beauty. I looked at the mirror behind him and saw my dark, emaciated reflection. "So anyway, I was washing my face in the ground floor washroom when this comes this really cute guy. I've seen him on campus a few times before. So anyway, he goes and takes a leak," Patrick paused. "You know those FC urinals, right?" I nodded. "No partitions." Patrick took another sip from his cup and continued. "So anyway, this guy sees me checking him out. To my surprise, he turns to me, giving me full view of him in all his glory and smiles. I smile back. And," Patrick took a deep breath, "the rest is for me alone to know." He ended by dabbing the sides of his napkin to his mouth. I knew pressing Patrick for more details would shut him up just like that so I let it pass. I could wheedle out all the details later. "So what's his name?" "Carlo." I raised an eyebrow and gave Patrick my you've-got-to-be-kidding look. He laughed and nodded in agreement. "Yes it's another Carlo. It's always Carlo, or Paolo, or Mike, or Jay--" "So what name...

...Activity 1.1.3 Gears – FT Introduction You do not have to look far to see gears. You might not think of an object such as a computer as having a lot of moving parts, but the CD tray on your computer is likely controlled by gears. A traditional watch is full of gears. The watch has one source of power or input that must move multiple hands continuously and at different speeds. Some watches also keep track of the day of the month. This may be low-tech by today’s standards, but imagine the challenge of choosing just the right gears to keep a watch synchronized. In a watch the gears are used to manipulate rotational speed. Gears are also used in many applications to control torque and rotational direction. Equipment fischertechnik gears and support pieces Calculator Procedure In this activity you will learn about gear ratios and how they affect speed and torque within a system. You will also construct simple and compound gear systems. Functions of Gears Gears change the speed of rotation. Gears change the direction of rotation. Gears change torque values. Gear Ratios By joining together two or more gears of different sizes, both the speed and the torque are changed from the input gear to the output gear. The larger gear within a system will always move slower and have more torque than the smaller gear. Gear Ratio (GR) is a comparison between the driver gear, also called the input (connected to the power source), and the gear being driven, or the output. Below are...
