Abstract:Ecosystem- based management(EBM) is a complex approach to better govern the environment that must always illustrate the collaborative trend in policy and public administration. Even in case of a bank its shareholder, customers and government’s involvement is almost always articulated.

However, one does not always know the outcome of the collaboration, but one can address this gap by developing and evaluating a set of hypothesis specifying how patterns of collaborations among different institutes affecting their joint ability to accomplish EBM.Ecosystem?based management (EBM) is presented to us in a positive approach to better govern the biosphere and has made its way into research and practices one different levels in regards to aerial, terrestrial and marine biomes. EBM stipulates a holistic approach to management, emphasizing that nature consists of myriad interacting components (e.g., species and the physical environment) that together give rise to systemic entities.Introduction:Althoug The Toronto-Dominion Bank is a chartered bank subject to the provisions of the Bank Act (Canada). It was formed on February 1, 1955 through the amalgamation of The Bank of Toronto, chartered in 1855, and The Dominion Bank, chartered in 1869.

(td.com, 2018) The branch of TD bank in westwood mall in Mississauga, Ontario was started in 2004.TD Canada has its headquarters in Toronto, Canada with over 85,000 employees in offices around the world. TD bank group and its subsidiaries is also collectively called the Toronto- Dominion Bank.

TD offers a wide range of financial products and services to more than 25 million worldwide through three major business lines:• Canadian Retail including TD Canada Trust, Business Banking, TD Auto Finance (Canada), TD Wealth (Canada), TD Direct Investing and TD Insurance• U.S. Retail including TD Bank, America’s Most Convenient Bank, TD Auto Finance (U.S.), TD Wealth (U.S.

) and TD’s investment in TD Ameritrade• Wholesale Banking including TD SecuritiesTD had CDN$1.3 trillion in assets on July 31, 2018. The company ranks among world’s leading financial services firm with approximately 12 million active users of its mobile and active users.

TD also trades in Toronto and NY stock exchange under the symbol “TD”.Integration:It is important part of EBM that there be integration of all three aspects. The aspects being social, economic and ecological goals. It is needed as one part of aspect cannot be dealt alone as they are interlinked.

According to pipap.sprep.org ecosystem based management is a framework for developing effective management plans based on an accepted set of guiding principles. This requires additions from different sections of ecosystem of which social, economic and ecological goals are a part of.

People throughout time have wanted to live in groups(that makes man social) helping each other financially (that makes man economically intelligent) while leaving little effect on the earth(man is ecologically conscious). Eliminating a certain aspect from all combined has rambunctious ramifications. According to integratedecosystemassessment.noaa.gov humans are a integral part of ecosystem. Within EBM, human and ecological well being are tightly coupled. Sustainability in both is only possible when they are addressed together. EBM by itself is too complex however by taking a step by step process that is adaptive one can learn and can move together in this holistic type of management.

Ecological Boundaries:When we look at the boundaries of the physical expansion of TD we find that it a strategy of the parent company to redefine itself in a place where there is deforestation due to construction of malls, buildings and houses to better accommodate the people living in Mississauga. TD is also looking after its ecological boundaries by providing grants to support environmental issues like green space programs and saving our natural resources. Eligible projects include schoolyard greening, park revitalization, community gardens, park programming and citizen science initiatives. TD is also the first bank to stop its carbon footprint by mailing letters made out of recycled paper.

On their website TD is commited to protect critical forest habitat and enhance neighbourhood green spaces through collaborations with environmental and community organizations across North America. natural processes and social systems, and using an adaptive management:Within the field of natural-resources management, the application of adaptive management is appropriate for complex problems high in uncertainty. Adaptive management is becoming an increasingly popular management-decision tool within the scientific community. McFadden, Hiller,Tyre (2011). The chosen branch of TD in Westwood mall has some of the largest population of African- Canadian and Indo- Canadian population in the country residing in its vicinity(worldpopulationreview.com, n.d ). As this place is a primary residence of immigrants having a branch in such a community has its own advantage.

The bank is offering different mentorship and events to new comers as this acts as social EBM for new Canadians(td.com,2018).I believe so because by integrating numerous people from the community into the program sponsored by TD it is establishing a economic growth as well as increasing social structure of Canada. The bank in Westwood mall is also providing competitive mortgage rate for new home buyers as well as for commercial areas. This will result in economic prosperity however, the land near the settlement is increasingly turned into malls or houses. This is where TD Canada in westwood mall fails to be an ideal EBM driver in the community.https://www.

People have the impression that police officers are frightening. At least, they uphold the law, and it is known that there are many corrupt officers. Indeed, such stories make headlines. But the reality is that police work is accomplished within a unique culture and structure just as a corporate culture exists in any business.

Police culture however transcends regional culture and it is not all the same. It has changed over the years. Many refer to the Blue Wall of silence, something that Serpico broke through some years ago, but one that remains on the front lines in many police departments around the nation. The blue wall comes about in some way because of the authority that exists within the department. In essence, the police officers can get away with looking the other way, which is exactly what the blue wall is. It is a concept that refers to the fact that police officers often cover for the illegal things that their coworkers are doing or better known as “Cops don’t tell on Cops” (Dempsey, Forst pg.

165), and in the end, it is difficult to break through and get to the truth. The idea that officers will cover the other’s back is entrenched in the culture and whistleblowers often are treating negatively. The infamous Serpico did blow the whistle when he went to the New York Times (Dempsey, Forst pg. 25). First, what is police culture? The idea of police culture is only loosely defined. It came about from a combination of shared norms, values, goals, career patterns, lifestyles, and occupational structures operating under the apparently rigid hierarchical structure which is different from tee combination held by the rest of society (Dempsey, Forst pg.

576). In other words, certain commonalities came to the forefront to define police work and police culture. The Blue Wall of Silence is simply one factor in evaluating Police culture, but the fact that it exists should not overshadow the overall culture.

This camaraderie, and a sense that police officers stick together, is only a part of the police culture. It should be noted that despite the fact that police forces are not connected through the nation—they are local entities—they each contain certain similar protocols. The officers wear uniforms, carry guns, work in a hierarchal organization and embrace certain strict rules. There is little flexibility or leniency in policing, though officers do have some discretion. At least, they do have to follow the law and if they stray, there is a right and wrong answer. Police officers are not creative directors or producers.

They follow the rules to the letter of the law and as stated in the mission statement “We will apply the law fairly and ethically, emphasizing quality in everything we do”. This is very much the same as the militaristic view that all rules are to be taken as law, and a superior officer is always right. The same type of setting is found in police stations across America. Yet, some settings are more lenient than others as community policing becomes more popular. Of course, in corrupt departments, the culture is a bit different as some rules are bent to different degrees. In some way, the hierarchical structure creates a culture on one hand, of perfection or at least an aim towards perfection, but on the other, it creates an atmosphere of unease. Many are aware that those in the military must make their beds perfectly, with no bit of blanket wrinkled. The gun must be cleaned just as well, and any stray from the requirement will likely lead to ridicule or punishment.

While police departments may not be that strict, the same attitude is generally present. While in some way, an organization entrenched in perfection is good, there is a drawback: police brutality. It seems that there is a backlash against the powers that be and it comes out in police behaving badly. There are many such cases when officers just snap at the end of a shift and beat a suspect, which is clearly stems from the stress that a police officer endure day in and out, the body has a natural reaction to stress it is known as the “flight-or-fight response” (Dempsey, Forst pg. 169).

Police Brutality still exists and over 26,000 cases reported in 2002 according to the Department of Justice (Dempsey, Forst pg. 246). It seems that the past traditions are somewhat gone, there are other aspects of policing that have faded too. There now seems to be little appreciation among young people regarding the complexity and variety police work can offer, or of skills developed in the course of police work, that can be transferred to other arenas. There is therefore the perception that policing offers limited opportunities. This is true in part because the world is rather specialized and it is often the case that experiences in other professions simply do not transfer easily. At the same time, policing is seen as outside of the scope of the business world.

Although this is the case, many police departments are now requiring either college degrees or at least some college, some of the most successful police recruiting operations are in high schools and colleges (Dempsey, Forst pg. 112). It seems that there may be more flexibility in the future for officers in terms of career changes. This in part may be due to increases in educational requirements. Thus, while there are police officers who command large salaries such as on Long Island, New York, it is still considered blue collar work.

To some extent, policing is not viewed as part of the general population. Indeed, the officers are a part of the government and not trying to make profit for a company. All of these factors play into the culture. It should be said that while the traditional police force is militaristic in nature, more and more bureaus have been moving towards community policing. There is a difference in culture between the community police officer and one who is entrenched in the traditional hierarchy.

The rigid structure is not aligned with the new culture that many police forces embrace. Clearly, there must be a meld of police culture and the larger culture. Much also depends on whether or not the police station is in Brooklyn or OshKosh. Large cities demand more complex structures and a paramilitaristic feel whereas small towns can cope with an Andy Griffith mentality, at least to an extent. While there is certainly a “police culture” in the United States, and even around the world, the flavor of that culture varies by region. Sometimes, the significance of this is slight, but sometimes it can make a tremendous difference. Finally, it becomes clear, in examining the history of policing and its changing culture that things are in fact changing. There are fewer police families and there is more ethnic diversity.

Today, officers are usually better educated and some command higher salaries than their friends and neighbors in private enterprise. Still, they are in their own business niche and while the blue wall has been disappearing to an extent, it is not completely gone. Obviously, the blue wall which came about due to old forged relationships, arrogance, outside culture and so forth, is fading but not fast enough. The blue wall is still present.

Should anything be done about this? It seems that community policing should be encouraged in order to change police culture and create a better future for policing and for the communities at large. Also, attention must be paid to police brutality. At the same time, the positive changes in police culture should be applauded.

No drastic changes seem to be necessary.

Abstract: two cities using TRANSYS software program

Abstract:The need for air conditioning in rural areas in which there is no source of traditional electrical power leads to look for an alternative solution by thermal solar energy. Usually the population of these areas uses typical movable house (TMH) for living. Solar thermal system drive vapor jet refrigeration cycle (VJRC) is an alternative solution replaces the vapor compression refrigeration cycle. Mathematical model will be carried out for (VJRC) using Engineering equation solver (EES) software program at various design conditions (generator, evaporator and condenser temperature). Especially attention on the performance of the cycle.

Cooling load for one TMH using TRNBuild software program will be estimated under standard design conditions for Hebron and Jericho cities.Hourly simulations for cooling load and solar thermal cooling system will be carried out over six months period (hottest months) considering climatic data for the two cities using TRANSYS software program coupling with EES. The performance of the overall system will be calculated. Energy consumption will evaluate. Effect of climate, evacuated tube solar collector tilt angle and area, hot storage tanks will study to meet the required human comfort, optimum operation conditions and parameters will be decided for the two climate regions.Introduction:The increasing demand for thermal comfort has led to a rapid increase in cooling system use and, consequently, electricity demand due to air-conditioning in buildings. The global contribution from buildings towards energy consumption, both residential and commercial, has steadily increased reaching figures between 20% and 40% in developed countries 1. Deployment of thermal energy refrigeration, using low-grade heat or solar energy, would provide a significant reduction of energy consumption.

Among the various technologies for thermal refrigeration, heat-driven ejector seems the most promising alternative to the traditional vapor compression refrigeration cycle. 2.vapor jet refrigeration cycle (VJRC) is simple to construct, rugged, low maintenance and has few or no moving parts making it a highly reliable system with an ability to run from low temperature solar heat or other waste heat, which can result in much cheaper operation of the cooling system.Ejectors are classified into two types depending on the position of the nozzle; constant-pressure mixing ejector and constant-area mixing ejector, in the constant-pressure mixing ejector the exit plane of the nozzle is located within the suction zone upstream of the constant area section, and the static pressure throughout the mixing zone is assumed constant.

In the constant-area mixing ejector, the primary nozzle exit is located in the constant area section, where the mixing of the primary and secondary flows occurs and the pressures of the two streams are not equal. The constant-pressure mixing ejector is used more than constant-area mixing ejector because it has higher entrainment ratio and COP at the same conditions.In (VJRC), water can be used as the refrigerant. Like air, it is perfectly safe. These systems were applied successfully to refrigeration in the early years of this century.

At low temperatures the saturation pressures are low (0.008129 bar at 4 °C) and the specific volumes are high (157.3 m3/kg at 4 °C). The temperatures that can be attained using water as a refrigerant are not low enough for most refrigeration applications but are in the range which may satisfy air-conditioning, cooling, or chilling requirements 3.

Using the water in VJRC Compared with other commonly used refrigerants (Halocarbons, hydrocarbon and mixtures refrigerants), water is inexpensive, has a high latent heat, and has minimal environment impact (ODP and GWP). VJRC can operate at low generator temperature around 100 °C. It can easily be powered by high efficiency flat plate or evacuated tube solar water collectors. Since the cooling load is commonly synchronized with the availability of solar energy, this becomes an attractive application of solar energy. Palestine is located within the solar countries and considered as one of the highest solar potential energy in the world, this makes it one of the best countries to use the solar thermal energy in the solar thermal air conditioning systems, especially in rural areas where there is no or insufficient electricity and there is a sufficient lands for solar collectors.Transient system simulation program (TRNSYS) and Engineering Equation Solver (EES) coupling are used to model and analyze the solar thermal refrigeration systems. EES software program is used to build a mathematical model of the refrigeration cycle and simulate the effect of operation conditions, and TRNSYS software program is used to simulate and analysis the system using solar thermal power system under different operation conditions and parameters at various regions and climate, and find the optimum design parameters for the system.

This simulation study based on constant-pressure mixing ejector with variable geometry using water as working fluid, the source of heat in the generator is the solar energy collected by solar collectors in two different cities in West Bank in Palestine, the cooling load of the cycle is used to cover the cooling demand for a TMH that commonly used in the rural areas in this cities. Problem: The global contribution from buildings towards energy consumption due air conditioning has steadily increased reaching about 30% in summer seasons in Palestine. In addition many rural areas in Palestine suffer from insufficient electricity that used in traditional air conditioning system to achieve the human comfort. This forced the population to used diesel generator to generate electricity demand that is high cost and non-sustainable.

Palestine is located within the solar countries and considered as one of the highest solar potential energy in the world, this makes it one of the best countries to use the solar thermal energy in the solar thermal refrigeration systems. Using the solar thermal energy to operate solar cooling systems is the best solution to reduce the fuel consumption, cost, harmful emissions and handle the peak time. VJRC is one of the most solar cooling systems that can operate at low generator temperature (around 100 °C) using evacuated solar collectors. Objective: • Investigate the performance of the VJRC: Computer modeling will carried out on single VJRC. The system will demonstrated on EES software program under various operation conditions, the generator temperatures of 80-120°C, evaporator temperature of 5-15°C and condenser temperature of 25-40°C. • Weather data collection and simulation: Weather data collection and filtration for Hebron city in the south of west bank and Jericho city in the east of west bank. Hourly simulation for weather data includes ambient temperature and solar radiation of the two cities mentioned. • Cooling load simulation: Hourly simulation for cooling load demand for a typical movable house used in rural areas at the two cities mentioned.

This house built at standard constructions in Palestine. • VJRC driven by solar energy simulation: Hourly simulation for VJRC driven by solar energy to supply the cooling load demand at different climate of the two cities mentioned above, and studies the effect of the different parameters on the performance of the system and human comfort and finds the optimum design parameters for the system, the simulation attention on the following:1- Investigate the effect of tilt angle of the solar collector in summer season.2- Investigate the effect of solar collector area.

3- Investigate the effect of thermal storage tank.Literature review The (VJRC) was first developed by Le Blanc and Parson in early 1900 and was very popular in early 1930’s for air-conditioning systems for large buildings. The system was replaced with the more favorable vapor compression system. The latter system was superior in its coefficient of performance (COP), flexibility and compactness in manufacturing and operation 4. Latter several mathematical models were developed to study 1-D ejector system with analysis and fluid dynamics theories applied to the primary and secondary flow. Tashtoush et al 5 studied the performance of the ejector cooling cycle.

They investigated the model mathematically using EES software. In addition, the ejector type , it is found that constant-pressure mixing ejector generates higher backpressure than constant-area mixing ejector for the same entrainment ratio and COP. and this is the reason behind used constant-pressure mixing ejector more than constant-area mixing ejector. The 1-D model of constant-pressure mixing ejector was initially developed in 1950 by Keenan et al. 6. In this model, the pressure of primary and secondary flow is equal at the nozzle exit.

The mixing of the two fluids starts with constant pressure and reaches the inlet of the constant area section. Their theory is still considered a successful model for constant pressure mixing ejector.According thermodynamics laws.

Many theoretical studies was carried out on operation conditions of the cycle such as the generator, condenser and evaporate temperature and pressure. Al-Khalidy7 and Rani8, noted that the performance of the system increased with increasing boiler and evaporator temperatures and decreasing condenser temperature.Eames et al 9, and Chunnanond et al 10 ,experimental studies was carried out on the fixed geometry ejectors refrigerator showed that, at each setting of boiler and evaporator operating condition, the operation of the ejector can be categorized into three regions as shown in Figure 1.2 double choked flow in the mixing chamber, primary chocking flow and reversed flow.

When the ejector is operated under the “critical condenser pressure”, COP and cooling capacity remain constant. Further increase in condenser pressure above the critical condenser pressure moves the thermodynamic shock wave into the mixing chamber and prevents secondary flow from reaching sonic velocity. Upstream conditions can now be transmitted downstream, which results in a reduction in secondary flow, entrainment ratio and COP. Eventually, secondary flow drops to zero, the ejector loses its function and primary flow will reverse back into the evaporator. Figure 1.

2: Ejector flow regimes 9When the flow through the primary nozzle is choked, the mass flow rate of steam does not increase when lowering the condenser pressure. This attribute of the nozzle is there as on for the constant entrainment lines as can be seen in figure 1.2.

From this it is noted that the most economical point to operate the ejector is at the critical point. From the results published by Chunnanond et al. 9 and Eames et al.

10 using water as refrigerant, they noted that lower boiler temperature can improve the COP of the system at the expense of critical condenser, also Ruangtrakoon et al.11experimental Results reported that decreasing boiler temperature decreases the critical condenser pressure and increases the entrainment ratio .Experimental results by Xiaoli Ma 12 using the water as refrigerant, Selvaraju 13 for R134a also conclude the same results.12 noted that the increase in the boiler temperature does not always cause an increase in the efficiency of the system. In the tested boiler temperature range of 84 to 96 C, the maximum COP (0.32) were obtained at boiler temperature of 90 C.13 Noted that the COP increases with the increase in generator temperature at particular condenser and evaporator temperatures.

This trend is observed up to a certain value of generator temperature and further increase brings about a reversal of the trend.Sun 14 experimental study was carried out on the variable geometry ejectors, it is noted that, with the variable geometry ejector. There are no critical pressure value and characteristics of constant capacity for variable geometry ejectors.

Also Increasing boiler temperature results in an increase in entrainment ratio and hence system COP. There is no optimum boiler temperature which gives maximum entrainment ratio. Thus, variable geometry ejectors overcome the inefficiency of fixed geometry ejectors. Figure 1.3 show the Effect of boiler temperature on ejector and cycle performance at condenser and evaporator temperature 35 ? C and 10 ? C respectively. Figure1.

3 Effect of boiler temperature on ejector and cycle performance 14.All the theoretical and experimental study 7-14 conclude that the performance of the cycle increased with increase the evaporator temperature and decrease the condenser temperature. Figure 1.4 and figure1.

5 show the effect of condenser and evaporator temperatures on the performance of the cycle 14. Figure 1.4 Effect of condenser temperature on ejector and cycle performance 14. Figure 1.5 Effect of evaporator temperature on ejector and cycle performance 14.

Alexis 15 Study the performance of an ejector cooling system driven by solar energy with R134a as working fluid. The system operating in conjunction with intermediate temperature solar collector in Athens, is predicted along the 5 months (May–September). He found that the COP of ejector cooling system varied from 0.035 to 0.199 when the operation conditions were: generator temperature (82–92 ?C), condenser temperature (32–40 ?C) and evaporator temperature (-10–0 ?C). For solar cooling application the COP of overall system varied from 0.014 to 0.101 with the same operation conditions and total solar radiation (536– 838 W/m2) in July.

Many researchers are used TRNSYS simulation for studying solar thermal cooling systems and refrigeration systems. Pridasawas 16 studied the effect of solar collector types and operation conditions on the VJRC performance with iso-butane as a refrigerant, Tashtoush et al 5 simulate the solar collector angle and area and study the performance of VJRC for the climatic conditions of Jordan with R134a as a refrigerant, Ahmed 17, and Asim 18 used TRNSYS to simulate the absorption cooling system under climate of Egypt and Pakistan respectively. Methodology:• Literature survey on solar cooling systems, (VJRC) working principal, solar thermal systems and simulation software programs.• Computer modeling for (VJRC) using the water as refrigerant on the (EES) program. The system will demonstrate and simulated under various operation conditions such as generator, condenser, and evaporator temperatures.

• Verification of simulation results with previous study at the same operation conditions.• Decide the cooling load zone locations and specifications.• Weather data collection and filtration for Hebron and Jericho cities.• Hourly simulation for ambient temperature and solar radiation of the two cities mentioned. • Decide the design conditions and human comfort conditions according codes and standards.

• Hourly simulation for cooling load demand for a typical movable house used in rural areas at the two cities mentioned. • Build and simulate solar thermal system operate the VJRC under the solar radiation and climatic data for Hebron and Jericho cities using TRNSYS software program.• Study the effect of tilt angle of the solar collector on the collected energy during summer season and decide the optimum angle in each city.• Study the effect of the climate on the cooling capacity and performance of the system.• Study the effect of the solar collector area on the cooling capacity and performance of the system.• Study the effect of the thermal storage tank capacity on the cooling capacity and performance of the system.• Study the effect of the (heat transfer fluid) HTF flow rate on the cooling capacity and performance of the system.• Find the optimum design parameters for Hebron and Jericho cities.• Writing the final report and results of the study.• Preparing for Writing scientific paper in the same topic.Outcomes/Results• The performance of the (VJRC) driven by solar energy depends on the design conditions and climatic data such as surrounding temperature and solar radiation.• Cooling load profile depends on the climate, location and the time of the system operation.• Using (VJRC) with a storage system can be achieve more human comfort than traditional AC especially at the peak times when the solar radiations and the surrounding temperatures are maximum.• Climate, solar collector area, hot storage tanks can strongly affect on the system efficiency and cooling capacity.
