bahaya rokok elektrik

Rokok elektrik banyak beredar di masyarakat Indonesia sebagai pengganti rokok biasa. Rokok elektrik tidak mengeluarkan asap pembakaran dan tidak meninggalkan bau menyengat. Rokok elektrik juga diklaim lebih sehat dan lebih nyaman dibandingkan dengan rokok biasa. Benarkah?

Ternyata kabar bahwa rokok tersebut lebih sehat dan lebih aman dibandingkan dengan rokok biasa itu tidak benar. Rokok elektrik ini juga memiliki nikotin yang sama beracunnya dengan rokok biasa. 

dampak asap rokok

Asap rokok adalah suatu bahaya bagi lingkungan yang sangat serius dan merupakan penyebab penting terganggunya kesehatan kita, baik bagi perokok maupun bagi kita yang tidak merokok. 

Asap rokok mengandung lebih dari 4.000 bahan kimia, termasuk zat yang sering dijumpai dalam kandungan polusi udara yang berbahaya, zat yang terdapat dalam sampah berbahaya, lebih dari 50 jenis zat penyebab kanker dan lebih dari 100 bahan kimia beracun lainnya. Beberapa zat yang telah familiar dengan kita diantaranya karbonmonoksida (menurunkan kadar oksigen), nikotin (penyebab kecanduan dan bisa menurunkan kerja otot hati), dan tar (campuran beragam zat-zat beracun). Bahkan, Environmental Protection Agency Amerika menggolongkan rokok sebagai karsinogen kelas A, disejajarkan dengan asbeston, arsenik, benzene, dan radon.

Banyak unsur beracun dari asap rokok yang bersifat genotoxic (misalnya: menyebabkan kerusakan pada sel DNA yang akhirnya mengakibatkan mutasi sel yang tidak terkendali atau kanker).

kenali kanker serviks

Gejala Kanker Serviks

Anda mungkin sama sekali tidak mengalami gejala kanker serviks – pada tahap awal kanker serviks biasanya tidak menunjukkan tanda dan gejala. Inilah mengapa pemeriksaan menjadi penting.

Tanda dan gejala kanker serviks pada tahap lanjut antara lain:

Pendarahan pada vagina ketika berhubungan, saat tidak dalam periode datang bulan atau setelah menopause.

Basah atau keluar darah pada vagina yang kental dan berbau.

Sakit pada pinggul atau nyeri ketika berhubungan.

Penyebab & Faktor Risiko (Penyebab Kanker Serviks)

Secara umum kanker terjadi karena mutasi sel normal menjadi sel yang tidak normal. Sel yang normal akan tumbuh dan melipatgandakan secara teratur. Akan tetapi sel kanker tumbuh dan melipatgandakan diri secara tidak terkontrol dan sel tersebut tidak mati. Akumulasi dari sel tersebut akan menjadi besar dan disebut dengan tumor. Sel kanker menyerang jaringan tubuh terdekat dan dapat memecah dari sumbernya untuk menyebar ke manapun di bagian tubuh.

ways of learning

It turns out everyone has different learning styles vary , among others :

a. Visual ( sight )
Children will be easier to learn when it is done by seeing to observe directly . Usually they find it difficult to follow a verbal explanation . Characteristic of children with a visual style is :
- More like the information through images , movies and posters
- Have a high imagination and style like doodling while the teacher explains
- Textbook with lots of well-liked image
The method used for children like this is use the pictures in learning .

b . Audio ( hearing )
More students absorb information if by speaking or making a sound when learning . They can follow the learning with lectures and discussions .
Methods that should be used is discussion , lectures , and voice recording .

learning to love yourself

learning to love yourself

1 . Respecting Yourself

Before you understand how to love yourself , you have to learn to respect yourself . It sounds so trivial , but if you really have respect for yourself? Have you stopped focusing on the shortcomings and focus on what you are good at. We are all human beings and all have benefits and drawbacks , whether it is visible to others or not . By simply acknowledging the negative side , then you can not be considered as people who love themselves .

2 . Start Loving Yourself !

Love and happiness comes from within , start loving yourself . Give yourself a reward after achieving something . Example after completing predetermined thesis , go to a restaurant that you've wanted or buy that item you really want for this . During this time you are too busy to appreciate others , giving gifts to others , praising others , fighting for each other , that's why you love others more than your own self . That 's why you're willing to be hurt as long as it has the status of dating with people who can not appreciate yourself .

 The lead could even be associate excerpt or scene from a story, book, movie, or TV show. These square measure smart as a result of your browser could have read or watched the scene already. This creates a affiliation, a bond, between the reader and also the writing by sharing footing.
The key to a lead is to produce a brief story your audience will relate to the topic of your writing, or to the mood or tone you want to determine.
The lead, on the opposite hand, is freelance of the content of the paragraph. It may well be faraway from the writing while not poignant the message (it may well be whole deleted and also the paragraph would still maintain its integrity). it's accustomed set the mood or tone within the reader, or to elicit a response toward the subject.
The leads is also as short as a sentence fragment, or as long as many sentences (maybe even a paragraph) long. generally we tend to need specific lead lengths, and different times we tend to leave it receptive the scholars to choose.

"observe your child"

Bullying has become a typical expertise for several youngsters and teenagers throught out our nation daily.  Recent surveys from the u.  s. Department of Justice, indicate that as several as half all youngsters that enter their college threshold daily square measure browbeaten at it slow throughout their year, and a minimum of half-hour square measure youngsters with special wants...FACT!

Bullying behavior is physical, verbal, racial, ethnic. Bullying by ladies is a lot of usually verbal, typically with another lady because the target.

Children United Nations agency square measure browbeaten expertise real suffering that may interfere with their social and emotional development, furthermore as their college performance. Some victims of bullying have even tried suicide instead of still endure such harassment and penalization.

"Linear Topology"

Computer Networks with Topology coherent ("Linear Topology") commonly referred to "Linear bus topology", this layout includes general layout. One main cable connecting each connection point (computer) that is connected to the connector called Connectors-T and the ends must be terminated with a terminator (terminator). BNC type connector used (British Naval Connector: Connector Maritime Britain), actually is a BNC connector name is not the name of the cord, the cable used is RG 58 (Sepaksi Thinnet Cables). Installation of beruntut bus topology is very simple and cheap but many can only consist of 5-7 computers.

     • Connectors BNC cable is used to connect the cable to the T connector.
     • T BNC Connectors are used to connect the cable to the computer.
     • tube BNC Connectors (BNC barrel connector) is used to connect 2
       BNC cable.
     • BNC terminator is used to marks the end of a bus topology.

"Mesh Topology"

"Mesh Topology" is a topology that was designed to have a level restoration with a variety of alternative routes or routing is usually prepared with the support of software or software.
 

"Ring topology"

"Ring topology" is called the topology of the network form series, each of which is connected to two other points, so that it can form a ring that resembles a circular path. Wires used in a ring topology BNC cable, therefore has no end it does not need a terminator. However, this topology has been widely abandoned because it has a weakness similar to a "bus topology" in addition, the development of a network using a ring topology is relatively difficult. In the ring topology all nodes / points function as repeaters which will amplify the signal along the circulation. It means every device work together to receive the signal from the previous device after it is forwarded to the device afterwards.
Excess "Topology Ring" (Ring):

• less cable.

• No data transmission will experience a collision (collision), because at one time only one node that can transmit data / data flow in one direction.

• Each computer has the right to equal access to the token sehinnga no hogging the computer network.

"Star Topology"

"Topology star" is a way to connect between one computer to another computer so as to form a network in the form of star shape (star). The star topology has the shape like a star / star, each node is connected centrally on a hardware hub or switch. Hub or switch used to connect each node in the LAN network. This tool is often used in a star topology and extended star. The only difference between Hub and Switch is the speed of data transfer. The cable used in this topology is a UTP cable with RJ-45 connectors.
The principle of a "star topology" is centralized control, all links must be through the center of the channel data to all nodes or client chooses. Central node called the primary station / server while the other is called the secondary station / client server. At the time of network connection initiated by the server, each client server can use network connections without waiting for orders from the server.
Pros: Flexible, Management and Development of the network easier, treatments performed in a node or Damage on a node does not affect other nodes, control center, ease of network management, detection and isolation of the damage / error easier.
Disadvantages: Requires special handling, centralized control (HUB) becomes a critical element.

"Bus Topology"

"Bus topology" is a topology that media transmission using a single cable or cable that connects the center of the client and the server. The both ends must be the terminator. This topology is actually quite simple and easy to handle, but at this time have many abandoned due to the density of traffic data and if there is a node that is damaged then the whole network can not function.
The following are the advantages and disadvantages of bus topology.
Advantages of bus topology:

• More Efficient cable, because the media only uses a single cable transmission and centralized so that it does not require a lot of wiring.

• Has a simple wiring layout, the installation of a bus topology wiring scheme and design that is used is very simple so installation is easier.

• Easy to develop, because the development of computer network both client and server can be done easily without disturbing the other computers. 

kinds of topology

Understanding the network topology is a technique to connect one computer to another computer that assemble into a network, where the network topology is based on the use of cost, speed of data access, the size and the level of connectivity that will affect the quality and efficiency network. 

There are a wide variety of network topology that many computers in use today include Bus Topology, Ring Topology, Star Topology, Mesh Topology, Linear Topology, each type of these topology has its own advantages and disadvantages.

"free education online"

The potential for educational applications of online learning has grown. Students are not only able to access knowledge from textbooks, but also be able to access course materials from outside the school. Teachers and students can obtain a lot of information, not limited, and can be accessed from several libraries around the world!

Students and teachers can improve classroom education by accessing information from various sources (databases, libraries, special interest groups), communicating via computer with other students or with experts in the particular field of study, and exchange information. Activities as done by national geographic allows students and teachers together to reap the benefits of connecting a national network of students, teachers, and scientists to investigate a variety of topics.
