Chem Basics

Chem BasicsA UMD Chemistry Library is used for the scientific work that is undertaken by students in a chemical engineering course. It is also the place where students can keep notes and records of their work on laboratory experiments.All materials used in a chemistry course are collected from various sources, including books, research papers, journals, and the school library. Students take up an inventory of the material required in a given class and classify them according to their uses and requirements. Materials are assigned to students who are registered in a course on a daily basis. On completion of each section of a class, students receive a final class schedule which lists down all materials required for the assignment.However, many students find that they have too much of the material to use in the course materials. In this case, they send their materials to the Chemistry Library to be sorted and separated into sections. Once a section is ready, it is divided into compartmen ts or bin boxes, so that the materials can be stored, so that they do not get mixed up.It is important to check the contents of each compartment to make sure that there are no expired or damaged bin boxes or any other damaged materials inside. Disposable folders are used to label the contents of each bin box. Once the compartment is empty, the material is safely removed and the student can then properly store the materials in their own storage.There are three main categories of materials that are kept in the UMD Chemistry Library: logbooks, laboratory and practice books, and reference materials. Labbooks contains all the materials required in a given lab session. Laboratory books contain the lab notes for every lab session that has been taken.References contain all the readings for the subject and topics discussed in the text. Students may take notes during their lab sessions in reference books or through study guides.The other materials used in a Chemical Engineering course at UMD include laboratory manual and laboratory instructions, equations, manipulatives, diluents, protoparticles, carbon, molecular apparatus, catalyst, thermodynamics, chemical kinetics, solid state reactions, and synthetic procedures. In addition, the UMD Chemistry Library includes several journals published by the College of Engineering, chemistry e-mail groups, the UMD web chemistry, and more.The Materials from the UMD Chemistry Library can be used in any class that is carried out by students at UMD. Materials can be placed in any of the compartments listed above to ensure that the correct materials are in reach when the students are working.

Square Root of Negative Number Online Tutoring

Square Root of Negative Number Online Tutoring Square root of a number is written under the square root radical symbol and the numbers inside the square root should be greater than or equal to 0 to get a real solution. But if a negative number is inside the square root, then the solution is known ias an imaginary solution and it is written in terms of i. Square root of -1 is equal to i and it represented as i = -1. Therefore square root of negative numbers gives imaginary solutions. Example 1: What is the value of the expression, (-4)? (-4i) can be split further in order to simplify the expression. This implies that (-4) = 4 * -1 Here, 4 can be written as 4 = (2 * 2) = 2 Therefore, 4 = 2 and this gives -4 = 4 * -1 == -4 = 2 * -1. And -1 is equal to i ==-4 = 2 * -1 = 2 * i Hence the value of the expression, (-4) = 2i Example 2: What is the value of the expression, -27? (-27) can be split further in order to simplify the expression. This implies that (-27) = 27 * -1 Here, 27 can be written as 27 = (3* 3 * 3) = 33. Therefore, 27 = 33 and this gives -27 = 27* -1 == -27 = 33* -1. And -1 is equal to i == -27= 33 * -1 = 33 * i Hence the value of the expression, (-27) = 3i3.

Nucleus

Nucleus Nucleus: Nucleus in biology can be very well defined as a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material. Nucleus can also be defined as a specialized, usually spherical mass of protoplasm encased in a double membrane, and found in most living eukaryotic cells, directing their growth, metabolism, and reproduction, and functioning in the transmission of genic characters. What is a Nucleus ? The nucleus is the controlling center of eukaryotic cell. It contains most of the genetic materials of the cell. It was first observed by Antonie von Leeuvenhoek in the lumen of RBCs and was named in the year 1833 by Robert brown who discovered it in plant cells. Structure of Nucleus: Nuclear Envelope: The nuclear envelope consists of two concentric membranes called the inner and outer membranes. The outer membrane is continuous with ER. In contrast the inner membrane carries unique proteins that are specific to the nucleus. A network of intermediate filaments present on the nuclear side of the inner membrane is known as nuclear lamina which is made up of lamin proteins providing mechanical support to the nucleus. Nuclear pores: The nuclear envelope contains nuclear pores for transport of macromolecules between cytoplasm and nucleus. Each nuclear pore is formed from an elaborate structure called nuclear pore complex. The proteins that make up the nuclear pore complex are known as nucleoporins. Nucleolar-organizing region (NORs): The nucleolus organizing region is a region of chromosome around which the nucleolus forms. In the human, the five chromosomes contain NORs, which can be identified as secondary constrictions on metaphase chromosomes. The position of secondary constriction in a chromosome is specific and species specific. As compared to secondary constrictions, the primary constrictions also called as centromere, attaches sister chromatids together. Chromosomes and chromatin: A chromatin is an organized structure of DNA and protein that is found in the nucleus of eukaryotic cells. It contains a single dsDNA in coiled and condensed form. The basic difference between chromatin and chromosomes is that chromatin is less condensed and extended DNA while chromosomes are highly condensed DNA. The extent of chromatin condensation varies during the life cycle of the cell. In non-dividing as well as interphase stages of cell, most of the chromatin remain relatively de-condensed. The light staining, less condensed portions of chromatin are termed as euchromatin. This region is transcriptionally active and contains most of the transcribing genes. The darkly stained and highly condensed region of chromatin is termed as heterochromatin. This region is transcriptionally inactive. img alt=chromosomes and chromatin data-cke-saved-src=http://images.tutorpace.com/biology/nucleus_5.jpg src=http://images.tutorpace.com/biology/nucleus_5.jpg 518px;= height:= 254px;= Centromere: The constricted region of linear chromosomes is known as the centromere. Although this constriction is called the centromere, it is usually not located exactly in the center of the chromosome and, in some cases, is located almost at the chromosomes end. Telomere: Telomeres are specialized structures, which cap the ends of eukaryotic chromosomes. It consists of a long array of short, tandemly repeated sequences. Origin of Replication: The origin of replication is a particular sequence in a chromosome at which replication is initiated. One chromosome contains multiple origins of replication. Chromosome number: All eukaryotic cells have multiple linear chromosomes. Every cell maintains a characteristic number of chromosomes. Depending upon the eukaryotic organism, the number of chromosomes varies from 2 to several hundreds. Chromosome number in different eukaryotic organisms: Species Haploid number of chromosomes Saccharomyces cerevisiae 16 Arabidopsis thaliana 06 Drosophila thaliana 04 Mus musculus 19 +X and Y Homo sapiens 22 + X and Y Functions of Nucleus: It is the prime control center of cellular activities. It controls the enzymatic activities. It controls the process of synthesizing proteins. It regulates the hereditary characteristics of an individual It participates in the process of cell division, differentiation and growth of cell. It controls the reliability of genes and its expression. Helps in the transport of RNA and DNA across the cell. Nucleolus is called ribosomal factory of the cell. Transcription takes place in nucleus.

Understanding Algebra

Understanding Algebra Algebra is one of the most important topics in Mathematics and it covers a huge range of important sub-topics which are very much necessary to understand the higher concepts of the subject. Algebra covering basics of math is known as Elementary algebra and understanding this portion is very important in order to do well in the other parts of math. Understanding algebra is the first step in understanding math as algebra starts from basic topics such as finding LCM and GCF of numbers, solving equations, absolute value of numbers etc. Example 1: Solve the given absolute value equation, |x 4| = 10. Given absolute value equation: |x 4| = 10. Since absolute value means distance of a number from 0, it is always positive. Hence the above equation splits into two ways: They are (x 4)= 10 and - (x 4)= 10- (x 4)= -10. Solve (x- 4)= 10 - x= 10+ 4 - x= 14 Solve (x 4)= -10 - x= -10+ 4 - x= -6. Hence we get: x = 14 and x = -6. Example 2: Find the midpoint between the two points (3, 4) and (5, 6). Given two points: (3, 4) and (5, 6). To calculate the midpoint betweenthe two points (x1, y1) and (x2, y2), we use the midpoint formula, given as: Midpoint = [(x1 + x2)/ 2, (y1 + y2)/2] Applying the above midpoint formula for the given two points, we get: Midpoint = [(3 + 5)/2, (4 + 6)/2] = (8/2, 10/2) = (4, 5). Therefore midpoint between the two points is (4, 5).
