Periodontitis is a chronic inflammatory disease of the supporting tissuessurrounding the teeth and can result in destruction of the periodontal ligament,cementum, connective tissue and alveolar bone (1). It is a major oral healthproblem in both developed and developing countries. It exhibits a wide range ofclinical, immunological and microbiological manifestations. It is characterizedclinically by gingival inflammation, bleeding on probing (BOP) from gingivalpockets, increased periodontal pocket depth, loss of clinical attachment level,recession of the gingival margin, alveolar bone loss, increased tooth mobility,drifting and eventually tooth loss. This often leads tocompromised function and aesthetics, and may be associated with pain anddiscomfort (2). In […]

In plants, sex determination is the processthrough which unisexual flowers are formed. There are two dominant ways ofunisexual flower development: One is the emergence of only one type of sexorgan without formation of any bisexual tissue at any stage floral development.Whereas in other; there is initiation of a bisexual floral meristem with bothstamens and pistils followed by a developmental arrest or abortion of one sexwith only the stamens or the carpels attaining functional maturity. The stepimpeding the development of floral sex organs is at an immature stage wellprior to reaching sexual maturity (reviewed by Kinney, Columbus, & Friar,2008). Many monoecious […]

.4 Saline tolerant rice farming and its impact                                                                 Themain concern is with the intrusion of saline waters in the surface watersystems which made land useless for paddy cultivation. According to scientistsof Bangladesh Water Development Board (BWDB) land with 500-1000 c.c. m salinityis cultivable but in Sundarban area it is 25-35 thousand c.c.m, in which normalrice cultivation is impossible but only 30 years ago it was 1500-4000 wherepeople could produce rice. Study identify six kind  of saline tolerant rice variety in thesouthwest Bangladesh and those are Bamonkhir, Beki Balam, ChiniKanai, Horkoch, Jamai nadu and Morich sal . The major cropping pattern […]

Arefrigerant is a substance that is normally a fluid, applied in the system of arefrigeration cycle. Throughout the refrigeration cycles, the refrigerantundergoes phase changes from a liquid to gas back and forth.Therefrigeration systems back from earlier era used chemicals such as ammonia (NH3),sulfur dioxide (SO2) and methyl chloride (CH3Cl). However,ammonia, sulfur dioxide and methyl chloride are toxic in nature. In the year of1920s, numerous lethal accidents were reported which was triggered by theleakage of methyl chloride from refrigerators. Following that incident, therehad been a joint effort by scientists and researchers to develop a less hazardousrefrigerants. Thecollaborative investigation of less dangerous […]

TumainNicholasMAT310December11, 2017.LIFEOF PI (?)Introduction          Pi, in mathematics, is the ratio ofthe circumference of a circle to its diameter. Thus, any circle divided by itsdiameter yields this unique number. There is not an exact time to trace when itwas invented as there is limited documentation on it from variousmathematicians. ? is an irrational number, which means that its value cannot beexpressed exactly as a fraction m/n, where m and n are integers. Consequently,its decimal representation never ends or repeats. It is also a transcendentalnumber, which implies, among other things, that no finite sequence of algebraicoperations on integers (powers, roots, sums, etc. […]

Theword “literacy” generally refers to reading and writing skills, whenyou focus on the word “digital” before it, the term signifies much,much more. Digital literacy has changed the traditional concept of literacy.Nowadays people are more often to consume the content from the web rather thanthat from print media. Newspaper television has contributed greatly in thefield of providing and sharing information. But now people are more up to thedigital medium of gathering information. Whilethe traditional method can be a one-way communication, digital writing isgenerally intended to be communicated to others.  Digital writing tools are designed to makethat easy for the end user.

INTRODUCTION A common problem challenged in mapping and surveying is the transformation of points from one coordinate system to another, but with the surveying technology accessible today there is a growing need to transform coordinates from one datum or coordinate system to another system.  For instance, a surveyor who works in a supposed coordinate system on a project may discover it is required to transfer the coordinates to can process the data with another system of coordinates. Moreover, coordinate transformations are used briefly in GPS surveying and in the field of photogrammetry. The methods presented here are some of the basic […]

 From the ancient time, people have been fascinated by thesun. Ancient civilizations expressed the sun as the supreme power, worshippingit as a God or Goddess .Farming and agriculture efforts have depended upon thesun’s rays to grow crops and provender .Recently we have developed the ability ofobtaining sun’s energy which is called “Solar power”. It is the conversion of solarenergy using photovoltaic’s (PV) system for electricity generation. Theresulting technologies have promising implications for the future of renewableenergy and sustainability. It is the cleanest andgreenest source of renewable energy.The way of harnessing energy from the sun is throughphotovoltaic (PV) system. A photovoltaic […]

Jessica MisakKristy JohnsonEnglish 10 Honors13 December 2017Transformation Through Exile: The Role of Isolation and Enrichment on the Development and Psyche of A Literary Character             One of the leading causes of dismay throughout the world is monophobia, the fear of being alone.  While psychologists have their own reasoning for monophobia, others believe this fear is because isolation forces one to be introspective about their deeply rooted flaws and their painful consequences. Though this process can be agonizing, it is vital for personal growth. In this regard, the Nigerian tome Things Fall Apart written by the father of modern African literature, Chinua […]

Chickpea (Cicer arietinum) considered as the real heartbeattrim in Pakistan, typically developed in the less watered zones. It requireswinter atmosphere however delicate to ice, additionally warm safe and blossomsunder great dampness conditions. The best time of sowing is amongst Septemberand November. Zone under aggregate development 1028.90 thousand ha andaggregate creation 479.5 thousand tons. There are two key types of chickpeanamed Desi and Kabuli . It is for the most part developed in rain-sustainedconditions in Thal territories of Punjab. The Punjab region alone contributesaround 80% of chickpea creation in the nation where the 90% territory ofchickpea is developed under rain-sustained conditions. […]
