The alpha-helix shown below is part of a water-soluble, globular protein. Note that some amino acids point \"toward\" you (Lys, Glu, Ser, Asp, etc.) and some point \"away\" from you (Phe, Ile, Val, Ile, etc.). Which side of the helix (the side with the amino acids pointing \"toward\" you or the side with the amino acids pointing \"away\" from you) would likely be the side of the helix that is in contact with the cytoplasm (the watery fluid inside all cells), as opposed facing inward toward the \"core\" of the protein? Solution Lys, Ser, Glu and Asp are hydrophilic amino acids whereas Phe, Ile, Val, Ile are hydrophobic amino acids. Hydrophilic amino acids seek contact with water whereas hydrophobic amino acids do not. The hydrophilic amino acids tend to be on the outside of the protein molecules. Therefore the hydrophilic amino acids would be in contact with the cytoplasm. The hydrophobic amino acids would tend to orient towards the interior of the folded protein molecule..

in java Can we create an object of type Interface? Explain your answer. Solution No, we cannot create an instance of interface in java because interface contains only abstract methods (ie. methods which are only declared) and as abstract methods do not have a body (of implementation code), we cannot create an object of interface. Though we can create instance of the class implementing the interface. But we can refer to object that implements an interface. example, public interface Pet { } public class Dog implements A { } public static void main(String[] args) { Pet ob = new Dog(); //Pet test = new Pet(); // compilation error } Also, Anonymous classes can implement interfaces, and it is the only time a class implementing an interface without the \"implements\" keyword. It is possible to create Interface object with anonymous inner classes as shown below : interface Sample { public void display(); } class Demo { Sample p = new Sample() { public void display() { System.out.println(\"Interfce example.\"); } }; }.

Explain the sources of police subculture. king undercover would affect an officer in terms of various components of police subeulture. Solution Answer- Part1 Police Subculture- It\'s the culture of Police Officers. Cops gathering at doughnut shops and eating doughnuts is part of police subculture which became popular. Cops are tied to the colour blue. They use police code even while not in the work-place. They call each other by their last names only outside of work as is standard practice while on the job. Part of cop subculture is to moonlight as bouncers, private eyes and other gigs when they can not get any overtime. Part of the culture is that cops live off their OT. If you look up how much cops get paid you\'ll find that OT is usually 20-50% of their wages. The culture has their slang. New Recruits are called Rooks/Boots. So, Police subculture is defined as a specific set of beliefs, attitudes, and behaviours exhibited by those in law enforcement. Because police officers spend the majority of their time dealing with crime, they tend to view members of the public as untrustworthy and potentially hostile. Sources of Police Subculture 1- Organization Factors Cont. 2- Night Shifts: 3- Street Environment 4- Culture-shaping implications between the police and citizens 5- Behavior can be influenced due to personal beliefs and circumstances that are encountered 6- Young officers get frustrated due to being disillusioned by the routine 7- Most common violent encounters that officers respond to are between friends and acquaintances, domestic situations also 8- Traffic stop interactions negatively affect police subculture, an encounter between officer and driver are doomed 9- Other Criminal Justice Agencies 10- Administration Cont. Answer- Part 2 Undercover officers are mainly hard-working minority men and women who grew up in some of the toughest neighbourhoods in the city who chose to come into the police and try to make a difference. And the police uses them. Working as an undercover would affect an officer in terms of various components of police subculture. Some Possible components could be as follows-: 1- Undercover agents are frequently required to be in hostile environments in which they give up control and do not have dominion. 2- The level of danger and unpredictability is markedly increased. 3- Their sense of moral superiority may be increased, as they spend more time surrounded by criminals. 4- Their sense of us versus them will have to be concealed to avoid giving themselves away. Their need for secrecy may extend to everyone they know to protect their cover, thus increasing their isolation. 5- Their bravery and ability to deceive are likely to be continually challenged..

Cuckoos are birds that practice brood parasitism. Instead of raising her own young, a mother cuckoo finds another bird’s nest and lays her egg when the other is away. The other bird dutifully cares for the cuckoo egg until it hatches. The cuckoo hatchling, before it can even see, senses the touch of other eggs in the nest and ejects them by pushing against them with its body. Characterize the hatchling’s behavior, using Tinbergen’s first two questions for understanding a behavior. What is the stimulus for the behavior? What is the response? How does prior experience influence the behavior? Solution The cuckoo is the best known brood parasite an expert in the art of cruel deception. Its strategy involves stealth, surprise and speed. Cuckoos will not build their own nest. Female cuckoos will find another bird’s nest and in the absence of the parent she removes one of the original egg and removing it from nest laying her own egg. Cuckoos parasitize the nests of a large variety of bird species and carefully mimic the colour and pattern of their own eggs to match that of their hosts. To give proper parental care to their egg. The bright red mouth act as stimulus to the foster parent to feed it regularly. It carefully mimic the colour and pattern of their own egg to match with the hosts..

Case Study Questions: What is the Major Problem identified in case (this is critical to the completion of the case)? What external issues affect the case? What are the 3 best alternative solutions in order of recommendation? Advantages and disadvantages for each solution? CASE STUDY TEXT: The executives who lead Voici Brands\' various businesses own their bottom lines. Now the CEO wants to centralize supply chain operations. The businesses may save money -- but the executives will lose control. How should this battle be fought? HBR\'s cases, which are fictional, present common managerial dilemmas and offer concrete solutions from experts. WHEN JACK EMMONS, CEO of Voici Brands, stepped into the vast, brightly lit production area of the \"supply chain city\" in Shanghai, his jaw dropped. An ocean of uniformly kerchiefed and aproned Chinese women bowed over their sewing. There must have been a thousand of them. \"Each workstation is limited to a six-inch stack of material,\" Xao Li, the sales representative, pointed out in skillful English. \"This floor is divided into three sections, one for each client. As you can see, our employees work under the best conditions. NGOs have nothing to complain about.\" Li led Jack and Robert Dodds, Voici\'s CFO and Jack\'s sidekick on this trip, along a glistening green aisle, past row upon row of busy workers. Jack watched, fascinated, as the workers deftly pulled thread and material through the machines. In the distance, Robert caught sight of a Caucasian woman wandering the aisles in one section of the production floor. \"Who is that over there?\" Robert asked. \"Ah,\" said Li, peering knowingly over his designer glasses at Robert, then at Jack. \"I believe she is an inspector for Marquise. Her presence here ensures the high and consistent quality that Marquise expects.\" The reference to Voici Brands\' major competitor was hardly lost on Jack. Two years earlier, Marquise had consolidated its supply chain operations by outsourcing all its product lines to the supply chain city. In doing so, Marquise had shrunk the time from fashion design to products\' arrival in its retail stores from 50 weeks to 60 days, boosting its bottom line by 20%. Only a small part of the increase in profits was due to lower Chinese labor costs. Most of it was due to the faster time to market, which allowed Marquise to respond more quickly to the whims of its fashion-conscious customers. As Jack and Robert followed their host out of the cavernous facility, Jack realized that the sewing operation was only the tip of the iceberg. Adjacent buildings housed every other stage of apparel production, such as weaving and fabric dyeing. In one dazzling, Silicon Valley-style office building, Chinese and Western engineers and designers worked side by side at large LCD screens. \"Our professionals can help you with every stage of production, in all your lines,\" said Li. \"We take care of everything right here, from design through delivery.

Consider three hypothetical countries, Kipr, Ispania, and Atlantida, that seek membership in the European Monetary Union (EMU). Suppose that the average inflation rate of the three European countries with the lowest inflation rates is 2.0%, and the average Interest rate of those countries is 2.2%. Evaluate the characteristics of Kpr, Ispania, and Atlantida presented In the following table using the Maastricht convergence criteria. Then, use the dropdown menus in the bottom row to identify whether each country is eligible to become an EMU member. Solution The nominal convergence criteria which must be met by the countries joining the Economic and Monetary Union were laid down in the European Union Treaty which is also known as the Maastricht Treaty. They include: The first three convergence criteria are designed to ensure monetary stability by supporting a fixed exchange rate regime among member countries. The stability of the euro is reinforced by the last two criteria, which protect the European Union from threats of inflation which may arise from government budget deficits. The Country KIPR cannot became a member of European Monitary Union (EMU) because this country is not fulfilling either of the critieria needed except the last criterion. The Country ISPANIA also cannot became a member of EMU because this country is not meeting the third criterion which requires not to devalue their exchange rate in the period of atleast two years. The Country ATLANTIA can became of member of EMU because this country is fulfilling all the requirements needed..

Answer the following questions with detailed justifications a) What is the bandwidth of the human voice? b) What is the bandwidth of our hearing process? c) What is the bandwidth used in mobile speech communications ? Solution a) A voice frequency (VF) or voice band is one of the frequencies, within part of the audio range, that is used for the transmission of speech. In telephony, the usable voice frequency band ranges from approximately 300 Hz to 3400 Hz. It is for this reason that the ultra low frequency band of the electromagnetic spectrum between 300 and 3000 Hz is also referred to as voice frequency, being the electromagnetic energy that represents acoustic energy at baseband. The bandwidth allocated for a single voice-frequency transmission channel is usually 4 kHz, including guard bands, allowing a sampling rate of 8 kHz to be used as the basis of the pulse code modulation system used for the digital PSTN. Per the Nyquist–Shannon sampling theorem, the sampling frequency (8 kHz) must be at least twice the highest component of the voice frequency via appropriate filtering prior to sampling at discrete times (4 kHz) for effective reconstruction of the voice signal. b) Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, though there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine investigation for hearing loss usually involves an audiogram which shows threshold levels relative to a normal. Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100 kHz. Elephants can hear sounds at 14–16 Hz, while some whales can hear subsonic sounds as low as 7 Hz (in water). c) The present day telephone infrastructure limits the bandwidth of telephonespeech to 300–3400 Hz, whereby conversational speech falls mostly within 50–8000 Hz..

The President of the United States recently referred to how the US Government was using SWIFT. Do you know why? (3) How would you compare the perils of maritime shipping to that of airfreight? (4) What is Lloyds of London and under what conditions might you use their services? Solution (1) In the event a company, entity or person on one of the following lists appears to match a potential party in an export transaction, additional due diligence is required before proceeding. Depending on which list the match was found, a match indicates either: there is a strict export prohibition; a specific license requirement; or the presence of a \"red flag\". Prior to taking any further actions, users are to consult the requirements of the specific list on which the company, entity or person is identified by reviewing the webpage of the agency responsible for the list. Denied Persons List A list of individuals and entities that have been denied export privileges. Any dealings with a party on this list that would violate the terms of its denial order are prohibited. Entity List The Entity List identifies foreign parties that are prohibited from receiving some or all items subject to the EAR unless the exporter secures a license. Those persons present a greater risk of diversion to weapons of mass destruction (WMD) programs, terrorism, or other activities contrary to U.S. national security or foreign policy interests. By publicly listing such persons, the Entity List is an important tool to prevent unauthorized trade in items subject to the EAR. BIS can add to the Entity List a foreign party, such as an individual, business, research institution, or government organization, for engaging in activities contrary to U.S. national security and/or foreign policy interests. In most instances, license exceptions are unavailable for the export, reexport, or transfer (in-country) to a party on the Entity List of items subject to the EAR. Rather, a prior license is required, usually subject to a policy of denial. For guidance concerning the prohibitions and license application review policy applicable to a particular party, please review that party\'s entry on the list. Procedures for removal from the Entity List appear in section 744.16 of the EAR. Unverified List A list of parties whose bona fides BIS has been unable to verify. No license exceptions may be used for exports, reexports, or transfers (in-country) to UVL parties. A statement must be obtained from such parties prior to shipping items not subject to a license requirement. See Section 744.15 of the EAR. Consolidated Screening List The Consolidated S
