Hammer crusher is an important machine in mining machinery industry and widely used in cement, building materials, chemical industry, electric power, mining industry, road, etc. Hammer crusher can crushing medium hardness materials. It can put the largest size of 600-1800 mm materials crushing to 25 mm or below 25 mm .Hammer crusher is divided into: single segment hammer crusher, efficient hammer crusher, sand machine, vertical shaft hammer crusher, reversible hammer crusher, etc. Hammer crusher composition by hammer crusher enclosure, rotor, hammer, counterattack lining plate, sieve, etc. The advantages of hammer crusher is : big crushing ratio (usually the 10 to 25, 50), high productive capacity, product evenly, the structure is simple, easy operation and maintenance, the phenomenon of after powder is less, low energy consumption per unit product, the weight of equipment is light, etc. The main working parts of hammer crusher is a rotor with hammer. The rotor is rotating high-speed in the crushing cavity of hammer crusher under the motor driving . The materials into the mouth from the upper feeding, and then broken by cutting and grinding under the high-speed motion of the hammer. There are many kinds of hammer crusher in the mining machinery market now, and also many manufacturers. You should choose the appropriate type according to the actual situation. Besides, our company also produces different kinds of breakers, mills, gringders, dryers, feeders, kilns, and etc.Hongxing is a famous cursher manufacturer in China which was established in 1960. Hongxing have many years experience of product hammer crusher. Our crusher have sold to all over the world, such as India, South Africa, Russia, Iran, Indonesia, uzbekistan .

Nowadays,it ‘s not rare for teachers to complain that their students are indifferent to others.Some are even worried that the young generation might become too selfish to shoulder the due responsibility for the future of China.To be sure,many of our young people cannot see eye to eye with this.However,from my direct observations as an university student,I must admit that we young people today are in general more self-centered and unsympathetic than our previous generations.To start with,many,if not most,young people choose to attend exclusively to their own needs.In their eyes,it is all too natural to seek satisfaction from what they do,even if it may cause inconvenience to others.Take my dormitory for example.It’s a common scene here that a roommate cheerfully talks to his girlfriend on the phone at midnight when others are struggling for a sound sleep.One may complain now and then,but to no avail.In fact,except me,the others live the dormitory life much in the same way.When I take a nap at noon,they often play cards without regard to my need.Life is a joy to them,but they often enjoy it to the neglect of others’feelings.In sharp contrast,our caring parents always pay heed to our needs and those of people around them.Whenever my father comes home late at night,he tiptoes in for fear that he might awake the family.Whenever my mother goes downstairs to morning fair,she always walks quietly lest she should disturb the neighbors.Moreover,our young people tend to be insensitive to others’ difficulty.When a classmate falls ill,few people offer to help;instead,they regard it as none of their business.Some students in my class come from poor family,but they are active mobile phone users,who may spend per month twice as much as what their parents earn from arduous labor.When asked why they behave so,they answer that their parents have the obligation to pay the bills.Personally,I detest their answer,for I know my parents never thought that way when they were…
Today’s technology has completely altered our lives and the way we once lived. Not long ago it was considered absolutely unreasonable to think everyone would own a cellphone whereas now it is unreasonable if you do not. Modern technology has been incredibly influential and beneficial to our society. Technological advancements such as organ transplants, robots and artificial intelligence are saving lives daily. However, some would say that most technological advances have been all but beneficial to society arguing that it is “dumbing down” Americans. Both sides have been studied and solidly argued by many.
Technology has been and will continue to grow nonstop. One new invention that is catching a lot of attention recently is the 3D printer. One can actually print a working three dimensional object such as a hammer, a rubix cube or anything one can think of. Recently someone actually printed out a working car by printing and assembling each individual part. With all of these unimaginable things becoming a reality, it is beginning to be just as difficult to remember where technology has come from as it is to imagine where it is going. Author Paul Boutin, in his article “A Technological Revolution”, explains that in 1954, Dr Joseph Murray performed the first ever successful organ transplant. “It was more than skillful surgery” (Boutin). Today around twenty five thousand Americans per year receive new organs. Also in 1954, the first “robot” was created and “five years later, the Massachusetts Institute of Technology founded its Artificial Intelligence Laboratory in a quest to mechanically mimic human minds as well as hands” (Boutin). None of which would even be possible without advancements in medicine and in technology. Technology is not only making things more comfortable and in a sense, “effortless” for humans but it is helping to save more and more lives everyday.
Modern technology is now also affecting the way we, as humans, communicate with…
Comparative Proteomics: Protein Profiler Lab
by Jonathan ThulsonBiology 113
October 6, 2013Lab Partner:
Proteomics is the study of proteins. Their functions, interactions with other proteins, cellular locations and levels at which they are expressed. The purpose of this lab was to compare the proteins present in different species of fish to be able to determine which species of fish have the closest relation. This can be determined based on which two fish species have the most proteins in common with one another. The Central Dogma of biology is a process in which a gene made of DNA is transcribed by a messenger RNA and then translated into a protein. Based on the Central Dogma of biology if two species have similar proteins, that means that they have similar DNA. At the start of this lab we did research about all the fish we would be doing the experiment on in order to create a thesis on which two of the fish would be the most similar. Based on the research from a database on fish (http://www.fishbase.net) I came up with the thesis that Salmon and Trout would be the most similar fish in the study. They would be the most similar because they live in the same areas, they are both freshwater fish, they both swim in the same way, they have similar diets and they have similar lifespans. So based on their similarities they would have similar proteins, and therefore similar DNA.
The method used in this lab to map the proteins was the method of Polyacrylamide gel electrophoresis. This method can be used to separate the proteins present in the fish muscle and separates them on size. Due to the fact that they are separated by size, the proteins can be compared because similar proteins with stop at the same spot in the gel. So measuring the bands that show up on the gel you can determine if different fish species have similar proteins. The first thing that is done is to extract the proteins from the…

McClelland’s Acquired Needs Theory
Understanding people’s personalities and the things that motivate them are essential elements to being an effective manager. Over the years there have been a wide range of studies, many of which building off of each other, in attempts to pinpoint the intrinsic and extrinsic things that influence employees. David McClelland, an American psychological theorist, developed one of the more popular models known today as McClelland’s Acquired Need’s Theory which was an extension of Maslow’s Hierarchy of Needs. In this theory he states that our needs are learned (or acquired) by our experiences and surrounding and outlines how our need for achievement, affiliation, and power can affect the actions of individuals (MindTools Ltd.). I will outline the characteristics of the three motivator’s listed in McClelland’s theory, and how they affect our actions.
The first dominant motivator is the need for achievement. This trait is associated with the need to set and accomplish challenging goals, taking calculated risk to accomplish these goals, and a desire for feedback (Wikipedia contributors). It is important for people motivated by achievement to set realistic, challenging, and achievable goals. In contrast, individuals who are not motivated by achievement may set unrealistically high goals so as not to be embarrassed by not achieving, or very easy to achieve goals to minimize the risk of failure (MindTools Ltd.). They prefer tasks that allow them to use their skills to overcome obstacles rather than luck (Swenson).
Achievement oriented individuals thrive in competitive environments and in working on activities that are important to him or her. These individuals work tend to work best alone, allowing them to focus their energy on the task (Swenson). Feedback is a key element to keeping an achiever motivated because of their desire to know what they’re doing right, and…
Chris BurrellMath Matters, Even for Little Kids
Deborah Stipek, Alan Schoenfeld, and Deanna GombyEducation Week Vol. 31, Issue 26, Pages 27,29Reading skills in kindergarten have always been a commonly known indicator of future academic success, however according to Debrah Stipeks article on Math Matters, a 2007 study “School Readiness and later Achievement” by Greg Duncan found that certain math concepts were the “most powerful predictors of later learning”.
These researchers believe that now is the time to increase focus on early math skills. Since Common Core has published the K-12 standards that should be used as a path to set early childhood standards. The authors know that this task will not be easy especially since there is a wide spectrum of pre-k schools, such as, Head Start and daycares that have diverse funding and requirements. They also are subject to a wide variety of teaching staff and high turnover rates. States should be encouraged to find effective, economical ways to get pre-k teachers proper training, so that accountability measures would be very difficult to set in place. Putting too much curriculum in a pre-k program would mean less time for developmentally appropriate play and social emotional development. Therefore the authors suggest creating a “developmentally appropriate, child-friendly curricula and materials” This curriculum should build on what the children already know so that they may enjoy learning. Children need to learn number sense not rote memorization of letters and numbers. Children need to be taught to problem solve using real world strategies such as shape sorters and geoboards. The authors recommend that teacher training be a priority. Teachers must be able to effectively teach and understand how to not only teach math to pre-k children, but how to assess it. If funding is an issue, the authors suggested hiring math coaches or peer teaching to help facilitate teacher training. The author states…
“Stay Hungry. Stay Foolish.”
There are many speakers in history that deliver not only a well-organized speech, but also a memorable speech. Within a speech it is important to capture your audiences attention and gain their respect. Of all the wonderful speakers in history, one that has captured my attention, as a model public speaker, is Steve Jobs. Steve Jobs wrote and delivered the commencement speech, “Stay Hungry. Stay Foolish.” This speech was delivered to the graduates of Stanford University, on June 12, 2005. In this speech Steve Jobs begins with:
“I’m honored to be with you today for your commencement from one of the finest universities in the world. Truth be told, I never graduated from college, and this is the closest I’ve ever gotten to a college graduation. Today, I want to tell you three stories from my life. That’s it. No big deal. Just three stories.”
With these words, Steve Jobs, a great leader and innovator, initiates an address that really shows his personal characteristics of a successful but simple man. He expresses how he has learned from every single event in his life and has followed his own heart and feelings towards a likely future for himself.
As stated, Jobs divided his speech into three parts; three different stories that converge in one idea. Jobs’ view as stated in his speech is, “Do what you love and love what you do – that is an invitation for every alumnus of Stanford University.” He takes his personal life lessons and shares his thoughts and experiences in order to encourage people to feel a real passion for their professions without caring about superficial matters. His first story, “Connecting the Dots”, is very revealing, while he advances in his narration, people are able to understand the real meaning of the title.
In the beginning of the speech, Jobs has a great Introduction. He immediately gets the audiences attention by excusing his significance and lowering himself. In the speech Jobs ends up revealing a fact that…

Music Used in Spirited Away Brings Emotions to the Audience
There are many elements in each film; however, music is one of most crucial elements in the film that helps us generate the feeling which makes us feel even more connected to the film as we are watching it (Pacific Cinematheque, 2). There are two types of sound in the music, diegetic and non-diegetic. Diegetic sound is the sound that is actually happening in the film such as dialogue and door slamming while non-diegetic is the opposite (Cohen, 253), (Pacific Cinematheque, 1). This essay will only focus on non-diegetic sound which is music. Spirited Away is one of the films that music is attached to many scenes, especially the music score that is played by only the musical instruments, which plays an important role to make the audience feel that connection towards the film.
In general, music in the opening credits is as an overture that intentionally provides us the theme of the film. During the film playing, the directors also put music in the scenes to suggest the upcoming events in the film both chronologically and non-chronogically as well as the information of the film such as the setting of a scene, progression of the plot, the characteristics of the protagonists and antagonists (Pacific Cinematheque, 1). Apart from the dialogues that the characters use in the film, music can also help the directors indicate the film’s genre by creating certain emotions through it. In other words, music is a significant source of emotion in the film (Cohen, 254). Furthermore, ethnic and cultural context of a film can be expressed by music (Pacific Cinematheque, 2).
All of the songs in Spirited Away are composed by Joe Hisaishi, one of the most renowned Japanese composers. Spirited Away’s music scores indicate the theme of love, loneliness, youth, and acceptance. Hisaishi states that “The Hollywood style of…
Adjusting To Another Culture. It is amazing to visit other cultures either for businesses, tourisms, or visiting a friend, but can you interact with the culture that you are going to? It’s known that it is important to adjust to other cultures even though it is a challenging process. Regardless of what country you are from, peoples will inevitably have an experience where he or she will adjust to other culture. Getting support through this experience will help you to have a more satisfying practice, both academically and personally. Even though I’m from Egypt, but when first time I traveled to it I had some difficulty getting through the Egyptian culture, especially in their accent, food, and their demeanor.The most annoying thing that you must get through when you go to a new culture is the language or the accent. Every culture has its own language where they interconnect each other by it. Some language have different accent, which have same words but in a different pronunciation. When I traveled to Egypt to my hometown for the first time I found people who talk the same language which is Arabic and talk the same accent that I talk which is the Egyptian accent, but in a different pronunciation than I’m used to hear and pronounce. It took me the whole vacation to know that type of accent’s pronunciation. My mother’s family (most of them ) talk’s the Egyptian’s accent so fast that after they finish a sentence I ask them to repeat, but my father’s family ( some of them )talks the Egyptian’s accent so slow that sometimes I ask them to finish faster. That’s why it is difficult for me to learn different accents, so what will happen if I will learn a new language? There are stuff that you must learn it when you go to a new culture, and get used to it such as food. I think that learning something is much easier than getting use to something. If your body is used for having a specific amount of fats, proteins, carbohydrates, vitamins, and minerals; then one…
My Major Fears
Bow!! That sound might make you freak out, and lose your brain. That sound is what really make that moment a scary moment. That is for a meager people, but other type of people get scary of accident, ghosts, heights, and other thing. I am the type of person who get scary from other things than Bow!!, but sometimes I get scary from Bow!! Also. I have three primary fears which are fear of God, fear of the judgment day, and fear of being asked about something bad or wrong I had done.
My major fear is the fear of God and the day that I will meet him. Those who believe in God, surely are afraid of him and fears him. Surely we should respect him and behave, because we want to be good people. I know that this type of fear applies in other religions, but noticing that Muslims say “fear of Allah (God)” a lot … not hating, just curious! Every religion have a god, and who believes in his God must fear him or selected deity. Fearing God is not like being scared of him as being scared of simple things, but to be feared him as awesomely respecting him.
My second primary fear is the fear of the judgment day. I fear I might be lonely there. That I would stay as a stranger between the whole of humanity; from the first person to the last that existed on Earth. I’m frightened of my life being replayed in front of the almighty. I fear my deeds would let me down on that ultimate day. They thought of this frightening day stimulates the thoughts of submission to God, to recap whole of my life and its deeds. And this reminds me of my ultimate goal in life; to win the days that counts. And that is my second primary fear.
I really get scary when someone asks me about something I did wrong, so what will happen when God asks me? The fear of God and the fear of judgment day leaves me with another fear. The fear of being asked about my life, my deeds, my sins. The day that I would be trailed. Trailed about my deeds, especially punishment I might receive for…
