Cerebral cortex; 4 lobes frontal parietal temporal occipital homunculus primary motor cortex primary somatosensory cortex Basal nuclei Diencephalon; 2 parts thalamus hypothalamus Cerebellum Brainstem: midbrain, pons, medulla oblongata medulla oblongata Limbic system Solution The brain consists of three main parts: 1) the forebrain 2) the midbrain and 3) the hindbrain. The forebrain is made up of cerebrum, thalamus and hypothalamus. The midbrain is made up of tectum and tegmentum. The hindbrain consists of cerebellum, pons and medulla. In the human brain, the cerebrum is the largest part which is associated with higher brain function. The cerebral cortex consists of 4 lobes which are: 1) frontal lobe: this is associated with reasoning, movement, parts of speech and emotions. 2) parietal lobe: this is associated with recognition and orientation that is perception of stimuli. 3) occipital lobe: this is associated with the visual process. 4) temporal lobe: this is associated with memory, speech, perception and recognition of auditory stimuli. Homunculus primary motor cortex helps the brain to monitor and control the movement of the body. While primary somatosensory cortex receives information such as pain or pressure relayed from the spinal cord. Thalamus is a mass of gray matter which is situated in the forebrain and has sensory and motor functions. It carries all the sensory information via neurons to the cortex. Hypothalamus controls the function of homeostasis, thirst, hunger, emotions, autonomic nervous system and circadian rhythms. Cerebellum regulates and coordinates the movement, posture and balance. Brain stem is situated underneath the limbic system and is associated with basic functions such as heartbeat, breathing, etc. The brain stem consists of midbrain, pons and medulla. The midbrain controls the function of body movement, vision and hearing. Pons helps in the sensory analysis and motor control and it is also associated with the movement and posture. Medulla oblongata helps in maintaining the body functions such as heartbeat and breathing. Limbic system consists of thalamus, hypothalamus, amygdala and hippocampus. Amygdala is associated with memory, emotion and fear. Hippocampus is involved in learning and memory..

The water is split providing the electrons for PSII, which then excites the electrons to the higher energy state by absorbing photons from the sunlight. At the higher energy state, these electrons are accepted by a electron acceptor that through series of electron transport chain donates the electrons to the PSI. In doing so it generates ATP from ADP and Pi. Then the electrons are again excited to higher energy state from PSI with absorption of photon from the sunlight. At higher energy state, the elctrons are accepted by electron acceptor. This donates the electron transport chain through seroes of protein, which produces NADPH in this process. By this way the energy from the sunlight is converted into the chemical energy in the NADPH reducing equivalents.

The Sarbanes-Oxlet act (SOX) was primarily enacted following the Enron and other scandals. It basically sought to remove the compliance and audit gaps that may lead to the same kind or scandals in future. This is considering the fact that these scandals lead to losses worth trillion dollars to the investors and the general public and hurts the image of corporates and government identically. The SOX was enacted for US corporations and sought to tighten accounting, financial reporting and audit practices to strengthen the basic foundations that may lead to humongous consequences. However the basic difference was that this act only was implemented to the corporations and management alike. The following were the major points which impacted corporations financial reports in a way that set a benchmark for all future compliances: This was basically set up to oversee the funtioning of independent audit firms which do compliance and financial audit for the specific companies. It was taken care that there the auditors be registered and there be specific set and defined processes which should be followed. All systems for process, compliance, quality control etc. were put in place to prevent any further slippage and mistake. This takes care of the utmost factor of independence of the audit firms. It seeks to minimize the conflict of interest that may arise in the event that a particular audit firm auditing the company is already providing some said non-audit service to the company. This is taken care of by this provision. This basically takes care of micro-reporting of sorts. There are enhanced reporting of all financial transactions i.e. off-balance-sheet transactions, any stock transactions of corporate management etc. The point also mandates strict internal controls for disclosures, and accuracy of the financial reports. It specifies audit controls and enhanced reviews by the SEC or its agents. This includes measures related to help and restore investor confidence. This paves way for investor confidence in reporting of securities analyst. This also mandates disclosures of conflict of interests is any and code of conduct for these analysts. This consists of sections which require the SEC with the Comptroller General to report specific findings. These reports include the effect of credit rating agencies, whether there are any securities violations, and whether any investment banks assist the companeis to manipulate financials. ALso reporting related to effects of consolidation of public accounting firms are provided in this. This seeks to provide whistle-blower protection for any information that they reveal. It mandates penalties i.e. criminal in sense, for alteration and manipulation of financial records. This is expecially a step ahead of point 8 in terms of the penalties. It recommends stronger and stricter sentences and implies that any failure to properly certify financial reports is a crimilThis section increases the criminal penalties associated.

Solution : This encryption scheme is not considered to be a secure one as the key used for encryption is very weak. It will be easy for Eve to crack the key and decrypt the message. The security provided here is very limited and it would not be possible for Alice to implement other elements of security to her encryption method. It would not be possible to add digital signatures to the encrypted message due to which it lacks repudiation. Authentication problem is also there with this weak encryption method. There is no surity of message integrity. Before reaching the destination it is possible that message gets modified to some extent or fully, of which the receiver or the sender will not be able to know. Sharing the key is also very dangerous as using any of electronic medium or magnetic medium is not safe. Due to insecure network the sender or the receiver may never know that the messages are being tapped. Sharing it in personal is only a safer method, but here distance and time becomes an obstacle in many cases. Alice used a method which have very limited security and thus insecure to send any message over the network. By modifying her method of encryption she could easily convert it into a healthy communication process.Strong keys will help her a lot and transferring it to the sender in a secure manner will add to it..

Smart Beta ia a rather elusive term in modern finance sometimes known as advanced beta,alternate beta or startegy indices.firstly theorized by Harry Markowitz , the first smart beta ETF was launched in 2003.A smart Beta ETF is a type of exchange-traded fund that uses alternative index construction rules instead of the typical cap-weighted index strategy, in a transparent way. It takes into account factors such as size, value and volatility. It utilizes both passive and active methods of investing ... passive because it follows an index, but active because it considers alternative factors. Smart Beta ETFs are ideal for investors hoping to maximize their income and returns and minimize risk. \"Smart\" refers to the use of an alternative methodology rather than following an index\'s size- based (market-cap) allocations.Its Evolution began with its namer\' Professional services firm Towers Watson .\"Smart beta strategies have seen huge inflows in recent years. According to ETF provider Invesco Powershares, from 2010 to 2017, Smart Beta ETFs took in more than 21% of U.S. equity ETF inflows, representing 12% of total ETF industry assets. Shifting On to the barriers for allocating smart beta in a investor`s portfolio investors have consistently reported that \"determining the best strategy or combination of strategies and managing unintended factor biases\" are the biggest concerns relating to implementation of a smart beta strategy.Finding the best variation is the issue of major concern for investors. Stating that excess returns mean extra risks for a smart beta strategy is not really a criticism of smart beta. Rather, it is a criticism of smart beta systems that claim to produce excess returns without assuming extra risks Smart beta is no different, regardless of how it is marketed. smart beta managers don\'t investigate the underlying economic logic behind performance, which can lead to problematic allocations.A smart beta construction is likely to be focused on past performance, because that is how factors are identified. Factors that show the strongest correlation with active management performance tend to be favored. That is as deep as the diagnosis goes with many smart beta mutual funds and exchange-traded funds (ETFs). One of the glorious things about market-cap-weighted indexes is that they\'re comparatively easy to run. Once you own all the stocks you want in their market weights, you generally don\'t need to touch the portfolio except to reinvest dividends, handle corporate actions and deal with index changes. Smart-beta strategies are holding securities in different weights, adjusting their portfolios to match their \"smart\" strategies, and often rebalancing regularly. All of that means that ETFs tracking smart-beta indexes often have a much more difficult time than their vanilla brethren. Apart from these short comings, investors need to have a deep insight of these matters while adding advanced beta to their portfolios. 1.. Not all s.

RNase P catalyzes the Mg2+-dependent 5\'-maturation of precursor tRNAs. Biochemical studies on the bacterial holoenzyme, composed of one catalytic RNase P RNA (RPR) and one RNase P protein (RPP), have helped understand the pleiotropic roles (including substrate/Mg2+ binding) by which a protein could facilitate RNA catalysis. As a model for uncovering the functional coordination among multiple proteins that aid an RNA catalyst, we use archaeal RNase P, which comprises one catalytic RPR and at least four RPPs. Exploiting our previous finding that these archaeal RPPs function as two binary RPP complexes (POP5•RPP30 and RPP21•RPP29), we prepared recombinant RPP pairs from three archaea and established interchangeability of subunits through homologous/heterologous assemblies. Our finding that archaeal POP5•RPP30 reconstituted with bacterial and organellar RPRs suggests functional overlap of this binary complex with the bacterial RPP and highlights their shared recognition of a phylogenetically-conserved RPR catalytic core, whose minimal attributes we further defined through deletion mutagenesis. Moreover, single-turnover kinetic studies revealed that while POP5•RPP30 is solely responsible for enhancing the RPR’s rate of precursor tRNA cleavage (by 60-fold), RPP21•RPP29 contributes to increased substrate affinity (by 16-fold). Collectively, these studies provide new perspectives on the functioning and evolution of an ancient, catalytic ribonucleoprotein. INTRODUCTION RNase P, a ribonucleoprotein (RNP), is the endoribonuclease that catalyzes the removal of 5\'-leaders in precursor tRNAs (pre-tRNAs) in all three domains of life (1–4). The bacterial variant is composed of 1 catalytic RNase P RNA (RPR) and 1 RNase P protein (RPP) cofactor. Eukaryal (nuclear) RNase P from yeast and human contain 1 RPR with 9 and 10 RPPs, respectively. Intermediate in complexity, the archaeal holoenzyme is associated with 1 RPR and at least 4 RPPs (POP5, RPP30, RPP21 and RPP29), which are homologous to eukaryal RPPs. Several years after the remarkable finding that the bacterial RPR is a true RNA enzyme in the presence of Mg2+ and monovalent ions (5), archaeal and eukaryal RPRs were also shown to be catalytically active in vitro (6,7). This common attribute of evolutionarily divergent RPRs was anticipated from their shared ancestry, attested by sequence and structural similarity of their putative catalytic core (8–15). However, dramatic variations (106-fold) in catalytic potential indicate that not all RPRs are equal: activity of RPRs from bacteria?>?archaea?>?eukarya (5–7). Although RPRs display activity in vitro without RPPs, they are dependent on their cognate protein cofactors for cellular function. Interestingly, there is an inverse relationship between RPR activity and RNP composition—the protein:RNA mass ratio is 70% in eukaryal and 50% in archaeal RNase P compared to 10% in their bacterial counterpart. Thus, elucidating the intimate cooperation between the RNA and.
