one of the main design goals for the java programming language is security. Explain, in detail how java achieves this goal? Solution 1.Security became an essential piece of a java language from the starting day itself.Additionally it is an progressing design aim of the java community .An intrinsic security is observed ,hence the java language is in much now-a-days which is the major cause. 2.Every action is possible through Java virtual machine(JVM) .it is mainly to establish the attributes like trust,integrity,confidentiality..etc. 3.Java offers large compile perusal ,leads with secondary stage of examining .language attributes motivates the programmers closely to good programming recurents. especially the memory management representation is uncomplicated.it removes the total classes of programing mistakes which causes a continous trouble to the C and C++ programmers.moreover the objects are fabricated with a new operator.precised programmer defined pointer data types, pointer arthematic and self-activated garbage collector is absent. 4.java language is manipulated in distributed domains that tells that the security is most important including the security attributes which is intended in the java language and run time system. 5.In case of network habitats ,the applications in java language are secured from interruption with an unofficial code venturing to acheive alrady the scenes and occupy file systems..

The aim to understand the language very easily get through the any problem to understand the basic and advance of any language. This website has been developed for every people to getting more knowledge for every person, share their knowledge and ready to get the job. What is Java Java is a programming language and a platform. Java is a high level, robust, object-oriented and secure programming language. It was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems' Java platform (Java 1.0 [J2SE]). The latest release of the Java Standard Edition is Java SE 10. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications. The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively. Java is guaranteed to be Write Once, Run Anywhere. Java String In Java, String is basically an object that represents sequence of char values. An array of characters works same as Java string. In Java programming language, strings are treated as objects. The Java platform provides the String class to create and manipulate strings. Exception in Java An exception is an unwanted or unexpected event, which occurs during the execution of a program i.e at run time, that disrupts the normal flow of the program’s instructions. Exception is an abnormal condition.In Java, an exception is an event that disrupts the normal flow of the program. It is an object which is thrown at runtime. What is Exception Handling Exception Handling is a mechanism to handle runtime errors such as ClassNotFoundException, IOException, SQLException, RemoteException, etc. Collections in Java The Collection in Java is a framework that provides an architecture to store and manipulate the group of objects. Java Collections can achieve all the operations that you perform on a data such as searching, sorting, insertion, manipulation, and deletion. Java Collection means a single unit of objects. Java Collection framework provides many interfaces (Set, List, Queue, Deque) and classes (ArrayList, Vector, LinkedList, PriorityQueue, HashSet, LinkedHashSet, TreeSet). The Java Collections Framework is a collection of interfaces and classes which helps in storing and processing the data efficiently. This framework has several useful classes which have tons of useful functions which makes a programmer task super easy.

What is Spring Spring is a lightweight framework and an open source Java platform that provides comprehensive infrastructure support for developing robust Java applications very easily and very rapidly. Spring framework was initially written by Rod Johnson and was first released under the Apache 2.0 license in June 2003. This tutorial has been written based on Spring Framework version 4.1.6 released in Mar 2015. It can be thought of as a framework of frameworks because it provides support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. The framework, in broader sense, can be defined as a structure where we find solution of the various technical problems. The Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc. We will learn these modules in next page. Let's understand the IOC and Dependency Injection first. Web Service A web service is any piece of software that makes itself available over the internet and uses a standardized XML messaging system. XML is used to encode all communications to a web service. For example, a client invokes a web service by sending an XML message, then waits for a corresponding XML response. As all communication is in XML, web services are not tied to any one operating system or programming language java can talk with Perl; Windows applications can talk with Unix applications. Web Services tutorial is designed for beginners and professionals providing basic and advanced concepts of web services such as protocols, SOAP, RESTful, java web service implementation, JAX-WS and JAX-RS tutorials and examples. Web service is a technology to communicate one programming language with another. For example, java programming language can interact with PHP and .Net by using web services. In other words, web service provides a way to achieve interoperability. Web services are self-contained, modular, and distributed.

Several obfuscation tools and software are available for Java programs but larger part of these software and tools just scramble the names of the classes or the identifiers that stored in a bytecode by replacing the identifiers and classes names with meaningless names. Unfortunately, these tools are week, since the java, compiler and java virtual machine (JVM) will never load and execute scrambled classes. However, these classes must be decrypted in order to enable JVM loaded them, which make it easy to intercept the original bytecode of programs at that point, as if it is not been obfuscated. In this paper, we presented a dynamic obfuscation technique for java programs. In order to deter reverse engineers from de-compilation of software, this technique integrates three levels of obfuscation, source code, lexical transformation and the data transformation level in which we obfuscate the data structures of the source code and byte-code transformation level. By combining these levels, we achieved a high level of code confusion, which makes the understanding or decompiling the java programs very complex or infeasible. The proposed technique implemented and tested successfully by many Java de-compilers, like JV, CAVJ, DJ, JBVD and AndroChef. The results show that all decompiles are deceived by the proposed obfuscation technique

What is Java Java is a programming language and a platform. Java is a high level, robust, object-oriented and secure programming language. It was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems' Java platform (Java 1.0 [J2SE]). The latest release of the Java Standard Edition is Java SE 10. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications. The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively. Java is guaranteed to be Write Once, Run Anywhere. Features of Java Object Oriented − In Java, everything is an Object. Java can be easily extended since it is based on the Object model. Platform Independent − Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on. Simple − Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it would be easy to master. Secure − With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption. Architecture-neutral − Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system. Portable − Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIX subset. Robust − Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking. Multithreaded − With Java's multithreaded feature it is possible to write programs that can perform many tasks simultaneously. This design feature allows the developers to construct interactive applications that can run smoothly. Interpreted − Java byte code is translated on the fly to native machine instructions and is not stored anywhere. The development process is more rapid and analytical since the linking is an incremental and light-weight process. High Performance − With the use of Just-In-Time compilers, Java enables high performance. Distributed − Java is designed for the distributed environment of the internet. Dynamic − Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment. Java programs can carry extensive amount of run-time information that can be used to verify and resolve accesses to objects on run-time. Basic concepts of OOPs are: Object Class Inheritance Polymorphism Abstraction Encapsulati

Solution The three major theoretical approaches:- 1) Symbolic interactionism 2) Conflict Theory 3) Functionalism Explanation:- 1) Symbolic interactionism:- emphasises on the language and symbols that help us to give meaning to the experiences in our life. It is basically slices of society. It is distinctive approach to the study of human life and human conduct. 2) Conflict Theory:- This theory argues that individuals and groups i.e., social classes within society have different amounts of material and non-material resources (such as the wealthy vs. the poor) and that the more powerful groups use their dominance and power in order to exploit groups with less power. 3) Functionalism:-This theory focuses how everyone take a part in society, how is the behaviour of the people in the society.

Studying Viruses can be important because they are often disease causing pathogens.

Concisely explain one example of how viruses were used to make a critical molecular genetics discovery (briefly, how was the experiment done, and what was concluded?) Solution Viruses are intracellular parasites that are effective after infecting particular host cells. Viral infection starts offevolved when proteins on the surface of a virion bind to particular receptor proteins at the host cells. The specificity of this interaction determines the host range of an endemic. Aside from being the causative agents of many sicknesses, viruses are vital gear in cellular biology research, mainly in research on macromolecular synthesis. Individual viral particles (virions) usually incorporate both an RNA or a DNA genome, surrounded via multiple copies of 1 or a small variety of coat proteins, forming the nucleocapsid. The nucleocapsid of many animal viruses is surrounded with the aid of a phospholipid bilayer, or envelope. During lytic replication, host-cell ribosomes and enzymes are used to explicit viral proteins, which then viral genome and package it into viral coats. The multiple progeny virions produced within a single infected cellular eventually are launched, following cellular lysis or gradual disintegration of the cell . Progeny nucleocapsids of enveloped viruses are launched by using budding of the host-cell membrane in which viral membrane proteins have been deposited. Some bacterial viruses (bacteriophages) might also go through lysogeny following infection of host cells. In this situation, the viral genome is incorporated into host-cell chromosomes, forming a prophage this is replicated along with the host genome. When suitably activated, a prophage enters the lytic cycle. All retroviruses and some different animal viruses can combine their genomes into host-cell chromosomes . In a few instances, this leads to abnormal cell replication and the eventual improvement of cancers. Recombinant viruses can be used as vectors to transduce genes into cells. In this method, viral genes required for the lytic cycle are changed with the aid of other genes. The use of viral vectors for gene remedy continues to be in its infancy, but has super ability for treatment of diverse diseases..

Proteins fold. How? Why? Solution ANS: Protein folding: Proteins are the molecules in the body which carries out many important functions, such as enzymes and antibodies. Before proteins carry out their function, they must first assemble themselves or fold. PROTEIN FOLDING MODELS: 1. Frame work model: In this the protein local elements which are stretches of amino acids liked by one another by covalently with peptide bonds. The region of the primary amino acids sequence in peptide bonds make different domains.in this domains some of regions are made with Alfa - helix and some are beta sheet domains. These primary elements form secondary structure independently of tertiary structure (kim and baldwin).these elements can diffuse until they collided, successfully adhering and coalescing to give the tertiary structure (diffus-collision model), (karplus and weaven). 2. The classic nucleation model: It postulates that some neighboring residues in the sequence would form native secondary structure that would act as a nucleus form which the native structure would propagate in a step wise manner. Thus the tertiary structure would form as necessary consequence of the secondary structure (wetlaufer). 3. Hydrophobic collapse model: It is hypothesized that a protein would collapse rapidly around its hydrophobic side chain and then arrange from restricted conformational space occupied by the intermediate. Here the secondary structure would be directed by native like tertiary structure (ptitsyn & kwajima). Leviathal’s paradox: It is formulated by Cyrus Leviathal. It explains, there are vast too many different possible conformations for a protein to fold by a random search. Structural organization of protein: 1. Primary Structure: the sequence of amino acids along with the di sulphide bonds. 2. SECONDARY STRUCTURE: Alfa Helices and Beta- Pleated sheets are most frequently occur in secondary structure in polypeptides. Both of these can case local folding of protein. The Alfa Helices in polypeptide made up of L- Alfa amino acids are right handed, the Alfa - Helices is stabilized by hydrogen bonds formed between oxygen and amide hydrogen’s of peptide bonds that are a part of linear sequence. Beta- Pleated sheets: 2 types A. Parallel: in this the adjacent hydrogen bonding segments are connected by cross over connection [Right handed]. B. Anti-Parallel: In this the adjacent hydrogen bonding segments are connected by HAIRPIN turns or reverse turn [Left Handed]. 3. Tertiary structure: It is arisen because of the folding of poly peptides upon itself. 4. Quaternary structure: Some proteins are made up of 2 or more polypeptides chains, the interaction between different poly peptide are subunits gives rise to the quaternary structure..

PLN 360/560 Environmental Impact Assessment Homework No. 4 1. An applicant has applied to the U.S. Army Corps of Engineers (USACE) for a Clean Water Act (CWA) Section 404 Permit to construct a marina at the mouth of Chaotic Creek on Bagel Bay on Lake Promise, a Water of the United States and Class \"B\" surface water in New York State. This site is located in the upper reach of a large commercial harbor used for deep-draft navigation. The project entails (1) construction of a breakwall; (2) dredging (and future maintenance dredging) of navigation entrance and creek channels; (3) installation of 50 docks with boat slips; and (4) construction of a boat launching ramp. During construction, it is estimated that a total of 60,000 cubic yards of material will be dredged and need to be managed, and about 2,500 cubic yards of fill will need to be placed in Lake Promise. Management alternatives for the dredged material include placement at an upland permitted municipal landfill, or discharge at a designated open- water site in the harbor. The site is an abandoned \"hole\" and since discharge of the dredged sediment is conceived to have benefits through reducing DDE bioaccumulation through capping and restoration of shallow water aquatic habitat, it is referred to as a habitat restoration site (HRS). The applicant had a consultant sample the sediments to be dredged for the marina as well as a lake reference area and HRS, and had the samples analyzed by a laboratory. The following is a summary of the test results that are to be submitted with the application: Contaminant Concentration in sediment sample of Concentration in Concentration in reference bulk HRS bulk marina sediment to be sediment sample sediment sample dredged Bulk Standard sediment elutriate (mg/kg)(mg/L) (mg/kg) (mg/kg) 13 0.02 Barium Cyanide Iron Mercury Dieldrin p.p\'- DDE Chlorobenzene 16 65 0.70 13,000 120 14 53 0.40 12,500 130 0.60 11,000 100 0.02 3x10-7 8x10 1.3x10 0.32 0.008 0.0034 0.12 1.3 38,000 Total organic 21,000 10,300 carbon (TOC) a.

Meyer and colleagues performed three rounds of X-ray crystallography, each with a different elastase crystal. For each experiment, they positioned the elastase crystal at a different angle. Why might researchers have rotated elastase crystals to position them at different angles? Select one: a. Similar to when you get X-rayed in different positions, X-rays would produce different images depending on the angle and position of the elastase crystal. Researchers likely rotated elastase crystals to different angles to understand the conformation of this enzyme from all sides. b. There was no reason for the researchers to rotate the elastase crystals. It would have been sufficient to carry out one X-ray crystallography experiment on an elastase crystal. c. Rotating the elastase crystals to different angles likely affected the rate of the enzymatic reaction; at a different angle, the hexapeptide substrate could remain bound to elastase for a longer period of time. There was thus more time to get detailed X-ray images. Solution a.Similar to when you get X-rayed in different positions,X-rays would produce different images depending on the angle and the position of the elactase crystal.Researchers likely rotated elastase crystals to different angles and position of the elactase crystal.Researchers likely rotated elactase crystals to different angles to understand to confirmation of this enzyme from all sides..

Numerous diseases are caused by problems in DNA replication or repair. For example, Bloom Syndrome is caused by a mutation in one of the helicase enzymes involved in DNA replication. Select one of the enzymes involved in DNA replication or repair and find a disease related to a mutation in this enzyme (a few of these diseases are mentioned in your textbook). Then, in at least 3 pages, address the following topics: 1. What is the specific mutation? 2. What are the symptoms of the disease? 3. How was the relationship between the mutation and the disease discovered? 4. How does this mutation impact DNA replication and repair and how is this different from normal DNA replication? 5. How does this mutation impact transcription and translation and how is this different from normal transcription and translation? 6. How does this problem in DNA replication lead to one symptom of the disease? 7. Give two examples of how genetic engineering technology could be used to learn more about, detect earlier, or treat this disease? Be sure to include a description of what genetic engineering is. You should write this Assignment as an integrated paper that addresses all the questions. This Assignment should not be done in question and answer format. Be sure to use appropriate headings for each section of the paper. Solution Disease caused :Progressive external ophthalmoplegia (PEO) is caused by mutations in mitochondrial DNA. 1.Specific mutation:Human mitochondrial DNA replication takes place by two-subunitsof DNA polymerase gamma (polgamma).Mutations in the polymerase and exonuclease domains of the human polgamma is the cause behind the occurence of PEO. 2.Symptoms of the disease: 3.Discovery of the relationship between DNA replication and repair: The diseases was discovered the symptoms that the patients experience followed by a genetic test on muscle biopsy sample.This led to the conclusion that there occured several deletions inmitochondrial DNA.Research further revealed that there occured mutations in polgamma on chrmosome 15q25.In particular, three autosomal dominant mutations were revealed that altered the amino acids located within polymerase motif B of polgamma. 4.Impact of mutation on DNA replication: The mutation resulted in dysfunctioning of the polgamma and thus some regions of the mitochondrial DNA are deleted in comparision to normal replication where the entire mitochondrial DNA is replicated fully. 5.Impact on transcription and translation: Mitochondrial DNA encodes 13 protein subunits of multimeric oxidative phosphorylation, 2 ribosomal RNAs and all the translated RNAs that are required for the translation of its own messenger RNA.In presence of mutations, some regions of mitochindrial DNA is not replicated and this leads to impaired protein synthesis. 6.Problem in DNA replication lead to one symptom of the disease: Deletions in segments of mitochondrial DNA leads to defective function of oxidative phosphorylation due to impaired protein synth.

In the Mexican swordtail fish, the wild-type color is olive-green. Other color variants include golden and Take caution with ratio there is some reduced viability in this system. Matings involving fish of these three phenotypes are shown below: Explain the inheritance of these color phenotypes in the fish Solution At any rate, the mode of inheritance of albinism in the goldfish has not hitherto been known. Using mates of different varieties of the goldfish, scientists arrived at the conclusion that albinism of the goldfish is not a simple Mendelian character but it is represented by the double homozygote of two non-linked autosomal recessive genes since because the F2 generation shows 15:1 ratio for non-albino and albino types like we see in the case of duplicate genes. example: If the animal was A/a, because a is recessive and A is dominant, the animal\'s phenotype wouldn\'t be albino, but it would still carry the gene for albinism (since it has an \"a\"). Since it carries both \"A\" and \"a\", it is known as \"heterozygous\". If the animal had the A/A combination, its phenotype wouldn\'t be albino, and it wouldn\'t carry the gene for albinism (both genes being the same, it is called \"homozygous\" for \"A\"). If it were homozygous for \"a\" (i.e. a/a), the animal\'s phenotype would be albino. Since \"a\" is recessive, both alleles need to be \"a\" in order for albinism to be expressed in the phenotype. The genes for the pigment cells are inherited independently of one another, and there is no known linkage to any other genes. So, each pigment type is coded by two different genes, one on each of a pair of chromosomes. The phenotype of wild type animals is dark, non-melanoid, non- albino and non-axanthic. The golden colour (D/D a/a or D/d a/a). It has normal migration of pigment cells, but lacks melanophores, hence the yellow/gold appearance..

If we maintain a strict biological definition of “species”, H. sapiens and H. neanderthalensis were NOT separate species as they successfully interbred. What impact might this information have on assigning a date to the origin of humans? Are there any other implications? Solution As we know the common male ancester is usually much younger than the common female ancester.Moreover the Mitochondrial DNA which is present in the Neanderthals and it is absent in humans Suppose we have related populations A, B and C and we can have that A can interbreed with B, and also the B can interbreed with C,.At the same time ,A can not interbreed with C. Noe a ccording to the strict BSC, the A and B are in the same species and at the same time B and C are in the same species, but A and C are not.These are the implications here. It is impossible to know the date of origins of humans due to difference between sapiens and neanderthals.we can fix one date on which an old species was found and can assume it to be the date of origin..

If taxpayers Monica, Traci , and Phillip are responsible persons in the failure to withhold and pay over employment taxes but only Monica and Traci acted willfully which of the following statements is correct? A the IRs may assess the trust fund recovery penalty against Monica , Traci and Phillip, but can only collect it from Monica and Traci b. The IRS can only asses and collect a trust fund recovery penalty from Phillip c. The IRS cannot assess a trust find recovery penalty against Phillip d. the IRS may asses a trust fund recovery penalty against Monica , Traci, and Phillip Solution The tax IRs may assess a trust recovery penalty against monica, traci, and phillip, but can only collect it from monica and trici. The employer need to withhold taxes from its employees wages and pay them to IRS. Withheld taxes are been said as trust fund taxes. When these taxes are not paid by the employer intenstionally or not to get paid the taxes IRs checks for the responsible person and willful person and upon all IRs may assess for thr trust fund recovery. IRs may ask for to pay the penality by any of the responsible persons..
