Neutron capture
It is believed that these heavier elements, and some isotopes of lighter elements, have been produced by successive capture of neutrons. Two processes of neutron capture may be distinguished: the r -process, rapid neutron capture; and the s -process, slow neutron capture. If neutrons are added to a stable nucleus, it is not long before the product nucleus becomes unstable and the neutron is converted into a proton. Outside a nucleus, a neutron decays into a proton and an electron by a process called beta decay (β-decay). Inside a nucleus it can be stable if the nucleus does not contain too many neutrons. In slow neutron capture, neutrons are added at a rate such that whenever an unstable nucleus is formed, it beta-decays before another neutron can be added. If neutrons can be added more rapidly, as in the r -process, the unstable nuclei formed cannot decay before additional neutrons are added until a nucleus is eventually produced that will not accept a further neutron. This nucleus, however, will eventually be subject to beta decay, thus permitting further neutron capture.

Conservation of Water
Water is one of the basic necessities for every living being and we cannot imagine a life without water. It is the natural resource and the main constituent of our planet earth. Water is the universal solvent and plays a key role in the existence of various forms of life on the planet earth. It is widely used for various purposes such as washing, bathing, cleaning, cooking, drinking, and other industrial and domestic uses.
Water is a colourless and odourless substance that is essential for the survival of living beings. There are various sources of water such as wells, rivers, ponds, lakes, oceans, big dams, and streams. As we all know, nearly 70 to 80 percent of the Earth’s surface is covered by water, among which only 1-2 per cent water is pure and suitable for human use.
Conservation of water mainly refers to protect, preserve, and control the usage of water and its resources. It is the system introduced to manage freshwater, reduce the wastage and protect the water and its resources in order to reduce and to avoid the scarcity. Therefore, we all should come forward to create awareness about conservation of water among our own friends, family, neighbours, society, etc. Conservation of water is very much essential as it saves life on earth.

The atomic nature of the elements
Paralleling the development of the concept of elements was an understanding of the nature of matter. At various times in history, matter has been considered to be either continuous or discontinuous. Continuous matter is postulated to be homogeneous and divisible without limit, each part exhibiting identical properties regardless of size. This was essentially the point of view taken by Aristotle when he associated his elemental qualities with continuous matter. Discontinuous matter, on the other hand, is conceived of as particulate—that is, divisible only up to a point, the point at which certain basic units called atoms are reached. According to this concept, also known as the atomic hypothesis, subdivision of the basic unit (atom) could give rise only to particles with profoundly different properties.

shoot systems
Entire shoot systems are often modified for such special functions as climbing, protection, adaptation to arid habitats, and water or food storage. The modifications generally involve structural and shape changes to the stem and the reduction of the leaves to small scales. Many of the modifications parallel those previously described for leaves. In the passion flower (Passiflora; Passifloraceae) and grape (Vitis vinifera; Vitaceae), axillary buds develop as tendrils with reduced leaves and suppressed axillary buds. In the grape these axillary tendrils are actually modified and reduced inflorescences. In the plant from which strychnine is obtained (Strychnos nux-vomica), the axillary buds develop into hooks for climbing.

Asparagus ornamental plants
Asparagus, (genus Asparagus), genus of the family Asparagaceae with up to 300 species native from Siberia to southern Africa. Best known is the garden asparagus (Asparagus officinalis), cultivated as a vegetable.for its succulent spring stalks. Several African species are grown as ornamental plants.
Asparagus species may be erect or climbing, and most of the species are more or less woody. The rhizomelike, or sometimes tuberous, roots give rise to conspicuous fernlike branchlets. True leaves are reduced to small scales. Many species are dioecious (individuals are either male or female), and the small greenish yellow flowers in the spring are followed by red berries in the fall. Members of the genus are characterized by the presence of cladodes, which are leaflike organs in the axils of the true leaves.

Article : Water substance composed of the chemical elements hydrogen and oxygen
Water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential compounds. A tasteless and odourless liquid at room temperature, it has the important ability to dissolve many other substances. Indeed, the versatility of water as a solvent is essential to live organisms. Life is believed to have originated in the aqueous solutions of the world’s oceans, and living organisms depend on aqueous solutions, such as blood and digestive juices, for biological processes. Water also exists on other planets and moons both within and beyond the solar system. In small quantities, water appears colourless, but water actually has an intrinsic blue colour caused by slight absorption of light at red wavelengths.

Drink Enough water
It’s common to get a little constipated if you don’t drink enough water. Inactivity, diet changes, illness, and even stress can add to the problem. Constipation usually passes on its own, but you can help move things along with exercise, over-the-counter meds, and of course, water.
See a doctor if your constipation lasts for more than a week or two or you have dizziness, bad pain in your belly, or blood in your stool. These could be signs of something more serious.

ADHD Students and Classroom Considerations
https://education.wm.edu/centers/ttac/documents/packets/adhd.pdf
The culture of the classroom can either support or create barriers to student success (Piffner,2011).
Factors that foster attention, positive behavior, and academic and social success includeestablishing positive relationships with students, adopting classroom management techniques,and creating a physical arrangement that facilitates learning.
It is often a positive relationship with one teacher that facilitates school success for a studentwith ADHD (Piffner, 2011).
When teachers connect with students and appreciate their unique skills and interests, students are more likely to strive for achievement and positively respond to classroom rules and procedures.
When using a proactive approach to classroom management, teachers support all students andcreate conditions that prepare them for learning (Piffner, 2011).
Some strategies for positive management include clear directions, meaningful feedback, and opportunities for collaboration with peers. Here are some others.
Opportunities to RespondStudents with ADHD often have the most trouble attending during drill-and-practice assignments because of the repetitive nature of the tasks. Peer-mediated approaches such as those enumerated in the next screens are particularly effective for students with ADHD in such cases, because they increase students’ opportunities for engagement and active learning (Piffner, 2011).
In creating peer-mediated activities, the teacher may need to choose students whoseskill levels complement each other. Students with and without attention difficulties andimpulsivity should be considered for peer partnerships.
Peer TutoringPeer tutoring is one of the more effective strategies for students with ADHD, because it provides many of the same supports as one-to-one instruction. It facilitates the acquisition of both academic and social skills.
Peer tutoring is most effective when training is provided to participating students (Piffner, 2011). Tutors need to be taught how to be prepared with materials needed for the session and howto give positive and corrective feedback to their partner (Greenwood & Delquadri,1995).
Cooperative LearningCarefully structured cooperative learning groups in which each student is assigned a role and has clear expectations for desired outcomes are very helpful for students with ADHD. The more structured the cooperative activity, the more likely it is that these students will succeed.Sharing Strategies Think, Pair, Share/Square Share/Group Share: Using thisapproach, students work with peer partners to discuss the lesson, check each other’swork, and share strategies.

natural language
The apparent fact that the number of utterances in a nThe apparent fact that the number of utterances in a natural language is unbounded is one of its more widely remarked upon properties and a core tenet of modern linguistic theory. The classic argument for creativity uses the idea that one can continually add further adjuncts to sentences to establish that there can be no longest sentence and therefore no finite number of sentences (see Chomsky, 1957). . . ."This conventional argument for the creativity of natural language is overly strained: who has actually heard a 500-word sentence? In contrast, anyone who studies [natural language] generation has available a far more reasonable and commonsense account of creativity, namely that one continually uses new utterances because one is continually faced with new situations. is unbounded is one of its more widely remarked upon properties and a core tenet of modern linguistic theory.

radiographic series (FMX)
A full mouth radiographic series (FMX) consists of 20 images composed of periapical (16) and bitewing (4) projections. Periapical radiographs are intended to evaluate the periapical region of the tooth and surrounding bone. Therefore, it is essential to obtain the full length of the tooth and at least 2 mm of periapical bone. Bitewing radiographs record, on a single image, the crowns and coronal 1/3 of the interproximal bone of both arches. Bitewings are useful for detecting interproximal carious lesions, bone height, pulp chamber size and shape, pulp stones, and overhangs on interproximal restorations. It is therefore essential to position the image receptor and x-ray beam so that there is an equal distribution of both arches in the resulting radiographic image. Instrument Assembly: The Rinn XCP Instrument for a full mouth series (FMX) of x-rays consists of 3 parts: 1. 3 biteblocks for the anterior, posterior, and bitewing set-ups. 2. 3 Indicator rods for the anterior, posterior, and bitewing set-ups. 3. 2 Aiming rings for the anterior, posterior, and bitewing set-ups. a. The same aiming ring is used for the anterior and bitewing set-ups

Sri Lanka - Agriculture
Agriculture is the most important sector of the Sri Lankan economy. Even though its contribution to the gross domestic product declined substantially during the past 3 decades (from 30 percent in 1970 to 21 percent in 2000), it is the most important source of employment for the majority of the Sri Lankan workforce. Approximately 38 percent of the total labor force was engaged in agriculture in 1999. In the subsistence sector, rice is the main crop and farming rice is the most important economic activity for the majority of the people living in rural areas. During the last 5 decades the rice sector grew rapidly and output more than tripled, reaching the highest ever output of 2.9 million metric tons in 1999. Increases in the area under cultivation, and improved productivity due to the modernization of agriculture are the main reasons for an increase in production. The rehabilitation of Sri Lanka's extensive ancient irrigation network and massive new investment in construction and maintenance of irrigation infrastructure led to a large increase in the area under rice cultivation. Between 1960-2000, the area used to grow rice increased 6 times to 546,249 hectares. The modernization of farming methods, such as the use of high-yielding seeds, tractors, and chemical fertilizers also led to increased productivity in the rice sector. Between 1960-1999, rice yield per hectare doubled from 1,877 kilograms to 3,672 kilograms. In addition to rice, various other food crops are produced for local consumption. They include yams, pulses, grains, vegetables, and fruits. Most of these crops are cultivated in family gardens, except for potatoes and sugar. Sugar cane is cultivated in the dry zone, and Sri Lanka produces only 15 percent of what it consumes domestically.Read more: https://www.nationsencyclopedia.com/economies/Asia-and-the-Pacific/Sri-Lanka-AGRICULTURE.html#ixzz6vrxdyz7V
