Zeena Housini 12B March 21, 2017 Contributions of Prominent Women in Islam In today’s world, Islam is misrepresented in almost every way and aspect. A major topic which is discussed many times is the role of women and how Islam views and treats women. In Islam, women are put on pedestals and given the utmost respect they deserve and in fact are given rights women in pre-Islamic times were not granted. These rights helped form some of the greatest, most courageous prominent women of our times. Islam has some of the most historically wise teachers, doctors, and leaders, a good number of which happen to be female. It is important to discuss the contributions of such females and to be educated on their success as it all†¦show more content†¦It is apparent that Zaynub had heavily made an impact on the people around in order for her to gain the nickname of being, â€Å"Mother of the Poor†. She was very kind and generous to the poor people around her and although anyone could act like so, it is apparent that she went out of her way to help t he poor. Her actions towards the poor show a role model manner in which they are to be treated. This contribution shows us, and future Muslims to come, how to humble ourselves and treat everyone we meet with basic human rights. Also, it exhibits the example of being kind and generous to those you met, whether they are rich or poor. So far, a prominent female Muslim teacher and a notable citizen have been covered; it is now time to cover an example of a prominent Muslimah leader. Asma bint Shihab Al-Sulayyhiya was the Queen of Yemen from 437-460 (AH) and ruled belong side her husband, King Ali bin Muhammad Al-Sulayhi. Asma is the perfect example of a strong and independent female political leader. She was known to make decisions and have a say in things that would happen during meetings and had an active role in state affairs. Also, Asma practically mentored the future Queen Arwa and taught her how to prepare for her future. Her presence in Islamic history encourages others to persist and showed many how to be an independent, knowledgeable, and wise leader. Just as there were prominent figures in the past during the reveal of Islam, there are also many courageous MuslimahsShow MoreRelatedContributions Of Prominent Women s Islam1326 Words   |  6 PagesContributions of Prominent Women in Islam Context The role of women in Islam has evolved over time. During the time of the Prophet Muhammad (SAW), as well as the era that shortly followed the Prophet’s death, women were given a great sense of power, freedom, and rights. However, because the Quran and hadith are open to many different interpretations, a male-dominated society began to slowly restrict the rights of women and slowly began to push their roles towards staying within the household andRead MoreContributions Of Prominent Women s Islam1005 Words   |  5 Pages 12B March 21, 2017 Contributions of Prominent Women in Islam The introduction of Islam into the early Arab culture elevated the status of women.

Authority of Leadership in Lord of the Flies by William...

â€Å"‘The rules!’ shouted Ralph. ‘You’re breaking the rules!’ ‘Who cares?’ Ralph summoned his wits: ‘Because the rules are the only thing we’ve got!’† (91). In Lord of the Flies, Ralph says this to Jack at one of their assemblies, after having berated the boys for neglecting the shelter building and the signal fires. Ralph’s leadership is built on these rules, and Jack’s breaking of them causes an ideological conflict between them which eventually leads to Ralph’s loss of power among the group. He tries to create a just and orderly society to fulfill their needs and allow them to be rescued, but the boys eventually find Jack’s churlish lethargy and excess to be more desirable. Desirable, as defined by the Oxford English Dictionary, can be†¦show more content†¦Piggy urges Ralph to use what power he has left by calling a meeting: â€Å"’What’s grown-ups goin g to say?’ cried Piggy again†¦The sound of mock hunting, hysterical laughter, and real terror came from the beach. ‘Blow the conch, Ralph...You got to be tough now. Make ‘em do what you want.’ Ralph answered in the cautious voice of one who rehearses a theorem. ‘If I blow the conch and they don’t come back; then we’ve had it. We shan’t keep the fire going. We’ll be like animals. We’ll never be rescued.’† In this situation, Piggy is still worried about the punishment of his previous life. He is the closest thing to an adult on the island, and Ralph is the only one who advocates listening to him, illustrating Ralph’s connection to the rules of traditional civilization, which the other boys despise and want to escape through the island. After showing blatant disregard to their â€Å"chief’s† rules, they decide to escape the constraints of Ralph’s assemblies and embr ace their inner savagery with Jack. Piggy urges Ralph to blow the conch, the symbol of his power throughout the book, but Ralph understands that his form of leadership is becoming the less desirable option to the boys: if he calls an assembly and the other boys do not respond, its power, and his civilization, will have completely disintegrated. Ralph constantly emphasizes their responsibilities on the island—specifically, tending to the signal fire.Show MoreRelatedWilliam Golding s Lord Of The Flies1389 Words   |  6 PagesA response to Lord Of The Flies Imagine an airplane crash.

string(93) " and Roger helplessly came, shaking his head, begging, crying, but helplessly going forward\." Chapter Twenty-Three The Bridge To The Stars Once lorek Byrnison was out of sight, Lyra felt a great weakness coming over her, and she turned blindly and felt for Pantalaimon, â€Å"Oh, Pan, dear, I can’t go on! I’m so frightened – and so tired – all this way, and I’m scared to death! I wish it was someone else instead of me, I do honestly!† Her daemon nuzzled at her neck in his cat form, warm and comforting. â€Å"I just don’t know what we got to do,† Lyra sobbed. â€Å"It’s too much for us, Pan, we can’t†¦Ã¢â‚¬  She clung to him blindly, rocking back and forth and letting the sobs cry out wildly over the bare snow.

Do they all hate children so much, that they want to tear them apart like this? Why do they do it?† But Pantalaimon had no answer; all he could do was hug her close. Little by little, as the storm of fear subsided, she came to a sense of herself again. She was Lyra, cold and frightened by all means, but herself. â€Å"I wish†¦Ã¢â‚¬  she said, and stopped. There was nothing that could be gained by wishing for it. A final deep shaky breath, and she was ready to go on. The moon had set by now, and the sky to the south was profoundly dark, though the billions of stars lay on it like diamonds on velvet. They were outshone, though, by the Aurora, outshone a hundred times. Never had Lyra seen it so brilliant and dramatic; with every twitch and shiver, new miracles of light danced across the sky. And behind the ever-changing gauze of light, that other world, that sunlit city, was clear and solid. The higher they climbed, the more the bleak land spread out below them. To the north lay the frozen sea, compacted here and there into ridges where two sheets of ice had pressed together, but otherwise flat and white and endless, reaching to the Pole itself and far beyond, featureless, lifeless, colorless, and bleak beyond Lyra’s imagination. To the east and west were more mountains, great jagged peaks thrusting sharply upward, their scarps piled high with snow and raked by the wind into bladelike edges as sharp as scimitars. To the south lay the way they had come, and Lyra looked most longingly back, to see if she could spy her dear friend lorek Byrnison and his troops; but nothing stirred on the wide plain. She was not even sure if she could see the burned wreckage of the zeppelin, or the crimson-stained snow around the corpses of the warriors. Pantalaimon flew high, and swooped back to her wrist in his owl form. â€Å"They’re just beyond the peak!† he said. â€Å"Lord Asriel’s laid out all his instruments, and Roger can’t get away – â€Å" And as he said that, the Aurora nickered and dimmed, like an anbaric bulb at the end of its life, and then went out altogether. In the gloom, though, Lyra sensed the presence of the Dust, for the air seemed to be full of dark intentions, like the forms of thoughts not yet born. In the enfolding dark she heard a cry: â€Å"Lyra! Lyra!† â€Å"I’m coming!† she cried back, and stumbled upward, clambering, sprawling, struggling, at the end of her strength; but hauling herself on and further on through the ghostly-gleaming snow. â€Å"Lyra! Lyra!† â€Å"I’m nearly there,† she gasped. â€Å"Nearly there, Roger!† Pantalaimon was changing rapidly, in his agitation: lion, ermine, eagle, wildcat, hare, salamander, owl, leopard, every form he’d ever taken, a kaleidoscope of forms among the Dust – â€Å"Lyra!† Then she reached the summit, and saw what was happening. Fifty yards away in the starlight Lord Asriel was twisting together two wires that led to his upturned sledge, on which stood a row of batteries and jars and pieces of apparatus, already frosted with crystals of cold. He was dressed in heavy furs, his face illuminated by the flame of a naphtha lamp. Crouching like the Sphinx beside him was his daemon, her beautiful spotted coat glossy with power, her tail moving lazily in the snow. In her mouth she held Roger’s daemon. The little creature was struggling, flapping, fighting, one moment a bird, the next a dog, then a cat, a rat, a bird again, and calling every moment to Roger himself, who was a few yards off, straining, trying to pull away against the heart-deep tug, and crying out with the pain and the cold. He was calling his daemon’s name, and calling Lyra; he ran to Lord Asriel and plucked his arm, and Lord Asriel brushed him aside. He tried again, crying and pleading, begging, sobbing, and Lord Asriel took no notice except to knock him to the ground. They were on the edge of a cliff. Beyond them was nothing but a huge illimitable dark. They were a thousand feet or more above the frozen sea. All this Lyra saw by starlight alone; but then, as Lord Asriel connected his wires, the Aurora blazed all of a sudden into brilliant life. Like the long finger of blinding power that plays between two terminals, except that this was a thousand miles high and ten thousand miles long: dipping, soaring, undulating, glowing, a cataract of glory. He was controlling it†¦ Or leading power down from it; for there was a wire running off a huge reel on the sledge, a wire that ran directly upward to the sky. Down from the dark swooped a raven, and Lyra knew it for a witch daemon. A witch was helping Lord Asriel, and she had flown that wire into the heights. And the Aurora was blazing again. He was nearly ready. He turned to Roger and beckoned, and Roger helplessly came, shaking his head, begging, crying, but helplessly going forward. You read "The Golden Compass Chapter Twenty-Three" in category "Essay examples" â€Å"No! Run!† Lyra cried, and hurled herself down the slope at him. Pantalaimon leaped at the snow leopard and snatched Roger’s daemon from her jaws. In a moment the snow leopard had leaped after him, and Pantalaimon let the other daemon go, and both young daemons, changing flick-flick-flick, turned and battled with the great spotted beast. She slashed left-right with needle-filled paws, and her snarling roar drowned even Lyra’s cries. Both children were fighting her, too; or fighting the forms in the turbid air, those dark intentions, that came thick and crowding down the streams of Dust – And the Aurora swayed above, its continual surging flicker picking out now this building, now that lake, now that row of palm trees, so close you’d think that you could step from this world to that. Lyra leaped up and seized Roger’s hand. She pulled hard, and then they tore away from Lord Asriel and ran, hand in hand, but Roger cried and twisted, because his daemon was caught again, held fast in the snow leopard’s jaws, and Lord Asriel himself was reaching down toward her with a wire; and Lyra knew the heart-convulsing pain of separation, and tried to stop – But they couldn’t stop. The cliff was sliding away beneath them. An entire shelf of snow, sliding inexorably down – The frozen sea, a thousand feet below – â€Å"LYRA!† Her heartbeats, leaping in anguish with Roger’s – Tight-clutching hands – His body, suddenly limp in hers; and high above, the greatest wonder. At the moment he fell still, the vault of heaven, star-studded, profound, was pierced as if by a spear. A jet of light, a jet of pure energy released like an arrow from a great bow, shot upward from the spot where Lord Asriel had joined the wire to Roger’s daemon. The sheets of light and color that were the Aurora tore apart; a great rending, grinding, crunching, tearing sound reached from one end of the universe to the other; there was dry land in the sky – Sunlight! Sunlight shining on the fur of a golden monkey†¦. For the fall of the snow shelf had halted; perhaps an unseen ledge had broken its fall; and Lyra could see, over the trampled snow of the summit, the golden monkey spring out of the air to the side of the leopard, and she saw the two daemons bristle, wary and powerful. The monkey’s tail was erect, the snow leopard’s swept powerfully from side to side. Then the monkey reached out a tentative paw, the leopard lowered her head with a graceful sensual acknowledgment, they touched – And when Lyra looked up from them, Mrs. Coulter herself stood there, clasped in Lord Asriel’s arms. Light played around them like sparks and beams of intense anbaric power. Lyra, helpless, could only imagine what had happened: somehow Mrs. Coulter must have crossed that chasm, and followed her up here†¦. Her own parents, together! And embracing so passionately: an undreamed-of thing. Her eyes were wide. Roger’s body lay in her arms, still, quiet, at rest. She heard her parents talking: Her mother said, â€Å"They’ll never allow it – â€Å" Her father said, â€Å"Allow it? We’ve gone beyond being allowed, as if we were children. I’ve made it possible for anyone to cross, if they wish.† â€Å"They’ll forbid it! They’ll seal it off and excommunicate anyone who tries!† â€Å"Too many people will want to. They won’t be able to prevent them. This will mean the end of the Church, Marisa, the end of the Magisterium, the end of all those centuries of darkness! Look at that light up there: that’s the sun of another world! Feel the warmth of it on your skin, now!† â€Å"They are stronger than anyone, Asriel! You don’t know – â€Å" â€Å"I don’t know? I? No one in the world knows better than I how strong the Church is! But it isn’t strong enough for this. The Dust will change everything, anyway. There’s no stopping it now.† â€Å"Is that what you wanted? To choke us and kill us all with sin and darkness?† â€Å"I wanted to break out, Marisa! And I have. Look, look at the palm trees waving on the shore! Can you feel that wind? A wind from another world! Feel it on your hair, on your face†¦.† Lord Asriel pushed back Mrs. Coulter’s hood and turned her head to the sky, running his hands through her hair. Lyra watched breathless, not daring to move a muscle. The woman clung to Lord Asriel as if she were dizzy, and shook her head, distressed. â€Å"No – no – they’re coming, Asriel – they know where I’ve gone-â€Å" â€Å"Then come with me, away and out of this world!† â€Å"I daren’t – â€Å" â€Å"You? Dare not? Your child would come. Your child would dare anything, and shame her mother.† â€Å"Then take her and welcome. She’s more yours than mine, Asriel.† â€Å"Not so. You took her in; you tried to mold her. You wanted her then.† â€Å"She was too coarse, too stubborn. I’d left it too late†¦.But where is she now? I followed her footsteps up†¦.† â€Å"You want her, still? Twice you’ve tried to hold her, and twice she’s got away. If I were her, I’d run, and keep on running, sooner than give you a third chance.† His hands, still clasping her head, tensed suddenly and drew her toward him in a passionate kiss. Lyra thought it seemed more like cruelty than love, and looked at their daemons, to see a strange sight: the snow leopard tense, crouching with her claws just pressing in the golden monkey’s flesh, and the monkey relaxed, blissful, swooning on the snow. Mrs. Coulter pulled fiercely back from the kiss and said, â€Å"No, Asriel – my place is in this world, not that – â€Å" â€Å"Come with me!† he said, urgent, powerful. â€Å"Come and work with me!† â€Å"We couldn’t work together, you and I.† â€Å"No? You and I could take the universe to pieces and put it together again, Marisa! We could find the source of Dust and stifle it forever! And you’d like to be part of that great work; don’t lie to me about it. Lie about everything else, lie about the Oblation Board, lie about your lovers – yes, I know about Boreal, and I care nothing – lie about the Church, lie about the child, even, but don’t lie about what you truly want†¦.† And their mouths were fastened together with a powerful greed. Their daemons were playing fiercely; the snow leopard rolled over on her back, and the monkey raked his claws in the soft fur of her neck, and she growled a deep rumble of pleasure. â€Å"If I don’t come, you’ll try and destroy me,† said Mrs. Coulter, breaking away. â€Å"Why should I want to destroy you?† he said, laughing, with the light of the other world shining around his head. â€Å"Come with me, work with me, and I’ll care whether you live or die. Stay here, and you lose my interest at once. Don’t flatter yourself that I’d give you a second’s thought. Now stay and work your mischief in this world, or come with me.† Mrs. Coulter hesitated; her eyes closed, she seemed to sway as if she were fainting; but she kept her balance and opened her eyes again, with an infinite beautiful sadness in them. â€Å"No,† she said. â€Å"No.† Their daemons were apart again. Lord Asriel reached down and curled his strong fingers into the snow leopard’s fur. Then he turned his back and walked away without another word. The golden monkey leaped into Mrs. Coulter’s arms, making little sounds of distress, reaching out to the snow leopard as she paced away, and Mrs. Coulter’s face was a mask of tears. Lyra could see them glinting; they were real. Then her mother turned, shaking with silent sobs, and moved down the mountain and out of Lyra’s sight. Lyra watched her coldly, and then looked up toward the sky. Such a vault of wonders she had never seen. The city hanging there so empty and silent looked new-made, waiting to be occupied; or asleep, waiting to be woken. The sun of that world was shining into this, making Lyra’s hands golden, melting the ice on Roger’s wolfskin hood, making his pale cheeks transparent, glistening in his open sightless eyes. She felt wrenched apart with unhappiness. And with anger, too; she could have killed her father; if she could have torn out his heart, she would have done so there and then, for what he’d done to Roger. And to her: tricking her: how dare he? She was still holding Roger’s body. Pantalaimon was saying something, but her mind was ablaze, and she didn’t hear until he pressed his wildcat claws into the back of her hand to make her. She blinked. â€Å"What? What?† â€Å"Dust!† he said. â€Å"What are you talking about?† â€Å"Dust. He’s going to find the source of Dust and destroy it, isn’t he?† â€Å"That’s what he said.† â€Å"And the Oblation Board and the Church and Bolvangar and Mrs. Coulter and all, they want to destroy it too, don’t they?† â€Å"Yeah†¦Or stop it affecting people†¦Why?† â€Å"Because if they all think Dust is bad, it must be good.† She didn’t speak. A little hiccup of excitement leaped in her chest. Pantalaimon went on: â€Å"We’ve heard them all talk about Dust, and they’re so afraid of it, and you know what? We believed them, even though we could see that what they were doing was wicked and evil and wrong†¦.We thought Dust must be bad too, because they were grown up and they said so. But what if it isn’t? What if it’s – â€Å" She said breathlessly, â€Å"Yeah! What if it’s really good†¦Ã¢â‚¬  She looked at him and saw his green wildcat eyes ablaze with her own excitement. She felt dizzy, as if the whole world were turning beneath her. If Dust were a good thing†¦If it were to be sought and welcomed and cherished†¦ â€Å"We could look for it too, Pan!† she said. That was what he wanted to hear. â€Å"We could get to it before he does,† he went on, â€Å"and†¦.† The enormousness of the task silenced them. Lyra looked up at the blazing sky. She was aware of how small they were, she and her daemon, in comparison with the majesty and vastness of the universe; and of how little they knew, in comparison with the profound mysteries above them. â€Å"We could,† Pantalaimon insisted. â€Å"We came all this way, didn’t we? We could do it.† â€Å"We got it wrong, though, Pan. We got it all wrong about Roger. We thought we were helping him†¦.† She choked, and kissed Roger’s still face clumsily, several times. â€Å"We got it wrong,† she said. â€Å"Next time we’ll check everything and ask all the questions we can think of, then.

Electropneumatics Book free essay sample

Production, assembly and packaging systems worldwide are driven by electropneumatic control systems. The change in requirements together with technical advances have had a considerable impact on the appearance of controls. In the signal control section, the relay has increasingly been replaced by the programmable logic controller in order to meet the growing demand for more flexibility. Modern electropneumatic controls also implement new concepts in the power section to meet the needs of modern industrial practice. Examples of this are the valve terminal, bus networking and proportional pneumatics. In introducing this topic, this textbook first looks at the structure and mode of operation of the components used for setting up an electropneumatic control. The following chapters then look at the approach to project planning and the implementation of electropneumatic controls using fully worked examples. Finally, the last chapter looks at trends and developments in Electropneumatics. We would welcome your comments on this book and will certainly consider your tips, criticism and ideas in respect of improvement. November 1997 The Authors TP201 †¢ Festo Didactic 5 Chapter 1 Chapter 1 Introduction Festo Didactic †¢ TP201 6 Chapter 1 1. 1 Applications of pneumatics Pneumatics deals the use of compressed air. Most commonly, compressed air is used to do mechanical work – that is to produce motion and to generate forces. Pneumatic drives have the task of converting the energy stored in compressed air into motion. Cylinders are most commonly used for pneumatic drives. The following section covers the basic terms used in control engineering. Control (DIN 9226, Part 1) Controlling – open loop control – is that process taking place in a system whereby one or more variables in the form of input variables exert influence on other variables in the form of output variables by reason of the laws which characterize the system. The distinguishing feature of open loop controlling is the open sequence of action via the individual transfer elements or the control chain. The term open loop control is widely used not only for the process of controlling but also for the plant as a whole. Application example A device closes metal cans with a lid. The closing process is triggered by operation of a pushbutton at the workplace. When the pushbutton is released, the piston retracts to the retracted end position. In this control, the position of the pushbutton (pushed, not pushed) is the input variable. The position of the pressing cylinder is the output variable. The loop is open because the output variable (position of the cylinder) has no influence on the input variable (position of the pushbutton). TP201 †¢ Festo Didactic 9 Chapter 1 Fig. 1. : Assembly device for mounting lids on cans Controls must evaluate and process information (for example, pushbutton pressed or not pressed). The information is represented by signals. A signal is a physical variable, for example ? The ? The pressure at a particular point in a pneumatic system voltage at a particular point in an electrical circuit Festo Didactic †¢ TP201 10 Chapter 1 Fig. 1. 4: Signal and information TP201 †¢ Festo Didactic 11 Chapter 1 A signal is the representation of information The representation is by means of the value or value pattern of the physical variable. An analog signal is a signal in which information is assigned point by point to a continuous value range of the signal parameter (DIN 19226, Part 5). In the case of a pressure gauge, each pressure value (information parameter) is assigned a particular display value (= information). If the signal rises or falls, the information changes continuously. A digital signal is a signal with a finite number of value ranges of the information parameter. Each value range is assigned a specific item of information (DIN 19226, Part 5). A pressure measuring system with a digital display shows the pressure in increments of 1 bar. There are 8 possible display values (0 to 7 bar) for a pressure range of 7 bar. That is, there eight possible value ranges for the information parameter. If the signal rises or falls, the information changes in increments. A binary signal is a digital signal with only two value ranges for the information parameter. These are normally designated o and 1 (DIN 19226, Part 5). A control lamp indicates whether a pneumatic system is being correctly supplied with compressed air. If the supply pressure (= signal) is below 5 bar, the control lamp is off (0 status). If the pressure is above 5 bar, the control lamp is on (1 status). Analog signal Application example Digital signal Application example Binary signal Application example Festo Didactic †¢ TP201 12 Chapter 1 Classification of controllers by type of information representation Controllers can be divided into different categories according to the type of information representation, into analogue, digital and binary controllers (DIN 19226, Part 5). Fig. 1. 5: Classification of controllers by type of information representation Logic controller Application example A logic controller generates output signals through logical association of input signals. The assembly device in Fig. 1. 3 is extended so that it can be operated from two positions. The two output signals are linked. The piston rod advances if either pushbutton 1 or 2 is pressed or if both are pressed. A sequence controller is characterized by its step by step operation. The next step can only be carried out when certain criteria are met. Drilling station. The first step is clamping of the workpiece. As soon as the piston rod of the clamping cylinder has reached the forward end position, this step has been completed. The second step is to advance the drill. When this motion has been completed (piston rod of drill feed cylinder in forward end position), the third step is carried out, etc. Sequence controller Application example TP201 †¢ Festo Didactic 13 Chapter 1 A controller can be divided into the functions signal input, signal processing, signal output and command execution. The mutual influence of these functions is shown by the signal flow diagram. ?Signals Signal flow in a control system from the signal input are logically associated (signal processing). Signals for signal input and signal process are low power signals. Both functions are part of the signal control section. the signal output stage, signals are amplified from low power to high power. Signal output forms the link between the signal control section and the power section. execution takes place at a high power level – that is, in order to reach a high speed (such as for fast ejection of a workpiece from a machine) or to exert a high force (such as for a press). Command execution belongs to the power section of a control system. Fig. 1. 6: Signal flow in a control system ?At ?Command The components in the circuit diagram of a purely pneumatic controller are arranged so that the signal flow is clear. Bottom up: input elements (such as manually operated valves), logical association elements (such as two-pressure valves), signal output elements (power valves, such as 5/2-way valves) and finally command execution (such as cylinders). Festo Didactic †¢ TP201 14 Chapter 1 1. 3 Pneumatic and electropneumatic control systems Both pneumatic and electropneumatic controllers have a pneumatic power section (See Fig. 1. 7 and 1. 8). The signal control section varies according to type. In ? In a pneumatic control pneumatic components are used, that is, various types of valves, sequencers, air barriers, etc. an electro-pneumatic control the signal control section is made up of a electrical components, for example with electrical input buttons, proximity switches, relays, or a programmable logic controller. The directional control valves form the interface between the signa l control section and the pneumatic power section in both types of controller.

For this reason, signal flow is not immediately clear from the arrangement of the components in the overall circuit diagram.
