why EI can not be used in determining protein primary structures? Solution EI is considered a hard (high fragmentation) ionization method, since it uses high energetic electrons to produce ions. This leads to extensive fragmentation, which can be helpful for structure determination of unknown compounds. EI is the most useful for organic compounds which have a molecular weight below 600. EI is useful for mass range <1000 Da, But Fragmentation of proteins in the 13000 to 29000Da mass range observed. Therefore, EI can not be used in determining protein primary structures .

Wile E- Coyote is dropping from cliff- but having been in this sort of.docx
Wile E. Coyote is dropping from cliff, but having been in this sort of situation before, he planned ahead. He is carrving an anvil that is ten times his own weight and plans to to throw the anvil downwards as he falls. He has calculated that he throws it hard enough, he will reduce his impact speed by half of what it would have been (if he just fell freely he\'d hit the ground at a speed of 24 m/s). How fast is the anvil going to be moving when it hits the ground, if all goes according to plan?
Solution
conserving momentum before and after throwing the anvil:
mass of the person*speed of the person when it hits ground without the anvil=mass of the person*impat speed after anvil is hit +mass of the anvil*impact speed for the anvil
==>m*24=m*(24/2)+10*m*impact speed of anvil
==>12*m=10*m*impact speed of anvil
==>impact speed of anvil=1.2 m/s

Goals for Business Ethics Education
Goals of business ethics education have included the teaching of ethical theory and the
particular contexts unique to making ethical decisions in the workplace (Morse, 1999).
The objective of some courses is to have an effect on student awareness of ethical
issues and attitudes towards ethics, while other courses focus on reasoning ability, with
a third type of course seeking to integrate the two objectives of awareness and

Why saturated suspended weight is less than dry weight and soaked weig.docx
Why saturated suspended weight is less than dry weight and soaked weight?
Solution
The Soil is made up of four phases namely Air, water ,voids and solid particles. The solid particles and the water present in the soil have both weight and occupy some volume. However, the air that is present in the soil does not have any weight.
in a saturated system of soil, the components of water and solids is present while the air component is completely removed from the soil.
In a dry soil,the component of water is absent while the pores (voids) of the soil is completely filled with air . So the weight of dry soil equals weight of only solids.
In a Soaked soil,the voids are filled u with water. So additional weight of water adds up.
In suspended saturated soil, the Buoyancy forces of water acts against the weight of soil. So i weighs less than the other kinds of soil

Why might a company accept a project or investment with an NPV less than zero?
Solution
A company accept a project or investment with an NPV less than zero due to many a points:
1. If a firm has poor corporate governance, managers may ignore the net present value rule. In order to appear active, management may take on negative NPV projects to give shareholders the illusion of ongoing corporate investment.
2. As the usefulness of net present value relies entirely upon accuracy of the expected income of a project and the discount rate. The company accepting a project of NPV less than zero on the assumption that the discount rate is set too high or expected income is too optimistic which has resulted in negative NPV. They accept the project on positive future.
3. If the Company is going with no business, then it might be tempted to accept a project with NPV less than zero.

Why does the absorption spectrum of as semiconductor have a sharp-stee.docx
Why does the absorption spectrum of as semiconductor have a sharp/steep region in the middle and two flat regions on either side? For emission spectrum, why is the emission peak typically sharp (narrow)?
Solution
molecules absorb light to different excited states. Emission comes from the lowest of these states, called the S1 state. When a molecule is excited to a higher state it often ends up in this lowest excited state S1 and then emits radiation. In this case the excitation spectrum is the same as the absorption spectrum. However from a higher excited state a molecule does not have to go to the lowest excited state. It can directly go to the ground state for instance. Then it does not emit radiation. In this case the excitation spectrum only has the lowest energy absoption features.

Solution
It important to understand culture so then you can pass down traditions , know about your close friends, you, and your family tree. As well as to know how to respect and appreciate others at what they do .
.....
There are many reasons why understanding different cultures is very important. A reason may be so that you can analyze things from a different point of view, outside you \"box\". Another reason is so that you can better understand why some people act the way they do and why they make certain decision because I think that the way someone gets brought up plays an important role in that. Some other reason is to respect other cultures and just enrich yourself with learning about new traditions etc..

Solution
In a low loaded network, the scheduler in each cell has an easy life as the amount of UE(user equipment)\'s simultaneous active is little. But LTE(Long Term Evolution) can prove its superior Frequency Domain Scheduling algorithm\'s (which are eNB Vendor specific) when the network gets loaded and RSRQ gets below -12 dB ... - 16 dB due to high interCell Interference from neighbor cells when looking at a particular serving cell. The Scheduler on its own can schedule the UE\'s in its own cell according to his scheduling algorithm and/or takes InterCell Interference Co-ordination signaling via X2-interface into account and be restricted to schedule cdertain Resource Blocks so that cell edge users are less interfered. This of course can be considered as a soft-reuse which enforces an re-use > 1.

Why is anion suppression necessary in ion chromatography-SolutionAnion.docx
Why is anion suppression necessary in ion chromatography?
Solution
Anion suppression is mandatory in ion chromatography, particularly in anion exchange chromatography. In suppressed ion chromatography, the sample is introduced and flows along with an eluent to the ion exchange column where separation occurs. After the separation, the mixture of ions in the eluent is introduced to a suppressor which exchanges the eluent and counter ions with suppressor derived ions. This exchange of the eluent has two practical advantages:
(i) The background conductivity of the eluent is reduced; this enhances the conductivity of the sample ions for easy detection by a conductivity detector.
(ii) The baseline noise is reduced; this increases the signal to noise ratio and thus, the sensitivity of the instrument.

why does an atoms electronegativity decrease down a column in the peri.docx
why does an atoms electronegativity decrease down a column in the period table but increases across the row in the periodic table?
Solution
The electronegativity decreases down the group because the bonding pair is far away from the nucleus because of addition of extra shells. This also leads to the pure shieling because the second period element will only be shielded 1s2 electrons whereas higher period elements will be shielded by 1s2 2s2 2p6 electrons. Hence the electronegativity decreases down the group
When we go from left to right in a period, the distance of presence of electrons remain the same, since we are in same shell but the charge on nucleus (increases due to increase in atomic number), the increase charge lead to attraction of electrons pair tightly making it more electronegative in nature

Why does iodine have a much lower melting point than sodium iodide- W.docx
Why does iodine have a much lower melting point than sodium iodide?
Why does iodine have a much lower melting point than sodium iodide?
Solution
Iodine occurs in a solid form and it is comprised of molecular bonds. In case of NaI, it is comprised of corresponding ionic bonds.
The lattice structure is formed in 1:1 ratio that means that for each Na + there exists I -
Hence the interaction will be stronger and in order to melt the crystal structure of NaI, all the ionic bonds need to be broken which results in high energy consumption.
Therefore, NaI has a higher melting point than Iodine.

Why do soluble impurities lower Tf of a solvent- Will insoluble impuri.docx
Why do soluble impurities lower Tf of a solvent? Will insoluble impurities lower Tf of a solvent?
Solution
T f stands for depression in freezing point. That is a decrease in the freezing point. A pure compound will have a unique freezing point at standard conditions. there will be some forces of attractions between the molecules of compound that held it together.(For example, crystalline solids will have well arreanged repearting unit cells and they are held together by some attraction forces. When some impurity is added to the crystalline solid, the arrangement of unit cells will be disturbed and hence the forces decreases. So, less energy will be sufficient to melt the solid). similarly, for any substance a large decrease inT f value is observed as the soluble impurity increases.
whereas, when insoluble impurities are present, they interact with the componud very less and hence only a slight decrease is observed in T f value.

It is because of the three golden rules set by the accounting principles:-
.
1)Debit what comes in , credit what goes out.
.
2)Debit the receiver, credit the giver.
.
3)Debit all expenses and losses, credit all incomes and gains.
.
When we purchase an asset it comes in our business- so we debit asset. So assets have a debit balance.
.
When we receive money from shareholders or loan from third party we credit them because we know -credit the giver.So. Liability and shareholder equity have a credit balance.

It important to understand culture so then you can pass down traditions , know about your close friends, you, and your family tree. As well as to know how to respect and appreciate others at what they do .
.....
There are many reasons why understanding different cultures is very important. A reason may be so that you can analyze things from a different point of view, outside you \"box\". Another reason is so that you can better understand why some people act the way they do and why they make certain decision because I think that the way someone gets brought up plays an important role in that. Some other reason is to respect other cultures and just enrich yourself with learning about new traditions etc..

Why is frequency reuse of 1 possible and what is the number of users p.docx
Why is frequency reuse of 1 possible and what is the number of users per carrier it allows?
Solution
In a low loaded network, the scheduler in each cell has an easy life as the amount of UE(user equipment)\'s simultaneous active is little. But LTE(Long Term Evolution) can prove its superior Frequency Domain Scheduling algorithm\'s (which are eNB Vendor specific) when the network gets loaded and RSRQ gets below -12 dB ... - 16 dB due to high interCell Interference from neighbor cells when looking at a particular serving cell. The Scheduler on its own can schedule the UE\'s in its own cell according to his scheduling algorithm and/or takes InterCell Interference Co-ordination signaling via X2-interface into account and be restricted to schedule cdertain Resource Blocks so that cell edge users are less interfered. This of course can be considered as a soft-reuse which enforces an re-use > 1.
No. of users >1

Why is anion suppression necessary in ion chromatography-SolutionAnion.docx
Why is anion suppression necessary in ion chromatography?
Solution
Anion suppression is mandatory in ion chromatography, particularly in anion exchange chromatography. In suppressed ion chromatography, the sample is introduced and flows along with an eluent to the ion exchange column where separation occurs. After the separation, the mixture of ions in the eluent is introduced to a suppressor which exchanges the eluent and counter ions with suppressor derived ions. This exchange of the eluent has two practical advantages:
(i) The background conductivity of the eluent is reduced; this enhances the conductivity of the sample ions for easy detection by a conductivity detector.
(ii) The baseline noise is reduced; this increases the signal to noise ratio and thus, the sensitivity of the instrument.

why does an atoms electronegativity decrease down a column in the peri.docx
why does an atoms electronegativity decrease down a column in the period table but increases across the row in the periodic table?
Solution
The electronegativity decreases down the group because the bonding pair is far away from the nucleus because of addition of extra shells. This also leads to the pure shieling because the second period element will only be shielded 1s2 electrons whereas higher period elements will be shielded by 1s2 2s2 2p6 electrons. Hence the electronegativity decreases down the group
When we go from left to right in a period, the distance of presence of electrons remain the same, since we are in same shell but the charge on nucleus (increases due to increase in atomic number), the increase charge lead to attraction of electrons pair tightly making it more electronegative in nature

Why does iodine have a much lower melting point than sodium iodide- W.docx
Why does iodine have a much lower melting point than sodium iodide?
Why does iodine have a much lower melting point than sodium iodide?
Solution
Iodine occurs in a solid form and it is comprised of molecular bonds. In case of NaI, it is comprised of corresponding ionic bonds.
The lattice structure is formed in 1:1 ratio that means that for each Na + there exists I -
Hence the interaction will be stronger and in order to melt the crystal structure of NaI, all the ionic bonds need to be broken which results in high energy consumption.
Therefore, NaI has a higher melting point than Iodine.

Why do soluble impurities lower Tf of a solvent- Will insoluble impuri.docx
Why do soluble impurities lower Tf of a solvent? Will insoluble impurities lower Tf of a solvent?
Solution
T f stands for depression in freezing point. That is a decrease in the freezing point. A pure compound will have a unique freezing point at standard conditions. there will be some forces of attractions between the molecules of compound that held it together.(For example, crystalline solids will have well arreanged repearting unit cells and they are held together by some attraction forces. When some impurity is added to the crystalline solid, the arrangement of unit cells will be disturbed and hence the forces decreases. So, less energy will be sufficient to melt the solid). similarly, for any substance a large decrease inT f value is observed as the soluble impurity increases.
whereas, when insoluble impurities are present, they interact with the componud very less and hence only a slight decrease is observed in T f value.

Why does this kind of error happen- It is something about makefile- an.docx
Why does this kind of error happen?
It is something about makefile, and it says I have two main function, why is it?
Solution
Error:
For creation of executable c- files, main funciton is the entry of the program execution.
If more than one main funciton causes this kind of error while creating a make file.
Error correction:
First make sure that no two main files are exist within the project .
Then make sure which c-file contains main function that starts and use the remaining c-files.
If countplus.c is main file that contains main function, then open sumnum.c and check if main function is exists .
then remove the main function from sumnum.c and save it.
If sumnum.c is main file that contains main function, then open countplus.c and check if main function is exists .
then remove the main function from countplus.c and save it.
and now create a make file.

Why does one firm in the same industry have a high ROE- one firm has a.docx
Why does one firm in the same industry have a high ROE, one firm has a low ROE, and what could be done to improve the lower performing firm based on ROE?
Solution
This ratio indicates how profitable a company is by comparing its net income to its average shareholders\' equity. The return on equity ratio (ROE) measures how much the shareholders earned for their investment in the company. The higher the ratio percentage, the more efficient management is in utilizing its equity base and the better return is to investors.
(1) causes of lower ROE are: low use of financial leverage, high degree of operating leverage, lower degree of profits, poor working capital turnover and fixed assets turnover, poor management of liquidity and high degree of taxes
A company can improve its return on equity in a number of ways,

Why do high levels of accruals appear to be mispriced-SolutionRichards.docx
Why do high levels of accruals appear to be mispriced?
Solution
Richardson, Sloan, Soliman, and Tuna find empirical evidence that suggests that accruals are related to earnings persistence. In addition, the less reliable the accruals, the lower the earnings persistence. Furthermore, they find that the market does not fully price the less reliable accruals.
Future stock returns appear to be negatively related to accruals, and the negative relation is stronger for less reliable accruals. Liu and Qi provide evidence that the potential mispricing of accruals is substantial.
There are a number of possible reasons for the mispricing. Na

why do assest accounts have a normal balance which is debit and liabil.docx
why do assest accounts have a normal balance which is debit and liabilites and stockholders equity have a normal balance which is credit?
Solution
It is because of the three golden rules set by the accounting principles:-
.
1)Debit what comes in , credit what goes out.
.
2)Debit the receiver, credit the giver.
.
3)Debit all expenses and losses, credit all incomes and gains.
.
When we purchase an asset it comes in our business- so we debit asset. So assets have a debit balance.
.
When we receive money from shareholders or loan from third party we credit them because we know -credit the giver.So. Liability and shareholder equity have a credit balance.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

why EI can not be used in determining protein primary structures-Solut.docx
- 1. why EI can not be used in determining protein primary structures? Solution EI is considered a hard (high fragmentation) ionization method, since it uses high energetic electrons to produce ions. This leads to extensive fragmentation, which can be helpful for structure determination of unknown compounds. EI is the most useful for organic compounds which have a molecular weight below 600. EI is useful for mass range <1000 Da, But Fragmentation of proteins in the 13000 to 29000Da mass range observed. Therefore, EI can not be used in determining protein primary structures
