Executive Summary The development of renewable and alternative energy is becoming more and more necessary as the traditional fossil fuel energy is a non-renewable energy and can cause various environmental problems such as the global warming effect. However, the challenge today in generating alternative energy is to find a cost effective way while has the smallest harmful environmental impacts. Developing bioenergy have the advantage of reducing greenhouse gas emission while creating great economic values. Introduction Biomass energy is considered as one of the renewable energies in the latest alternative energy sources development. According to the renewable energy consumption source data Table. I from U.S energy information administration, biomass energy is the largest source of renewable energies and the total share of biomass energy among all of the five alternative energies is approximately 50%. Although there is a 2.3% decrement of total consumption of biomass energy from 2014 to 2015 due to the decrease of wood consumption, there’s still a large potential for the bioenergy technology growth. Table I. Total consumption source of renewable energy.

The â€Å"Ah Hal† moment is distributed leadership actually did happened in my past appointment as the Course Commander in the Engineer Training Institute (ET). Being selected in the appointment and the most senior in rank, I naturally assumed the position of the leader with my subordinates taking Instructions from me. However, for certain events such as organizing of unit’s Chinese New Year event, managing of officer cadets’ cohesion activities, and specific training packages, I delegated the planning to my team.

Hence, It Is of my view that It Is Indeed possible that distributed leadership can be Implemented quite successfully In certain areas In SAFE. My post-action review Len- relation to the concept of Orpheus are being summarized in three points. Firstly, application of distr ibuted leadership can be applied in military context particularly for a small group who had attained a certain level of military competencies. It provides opportunities for a rotational leadership role, allowing any individual to merge as leader and to realize the rich potential as a group. Secondly, the empowerment given to the Individual must be respected and trusted to reduce their authority and leadership through a shared vision, mission and purpose. The concept will allow the group to generate greater passion and motivation to reach the desired outcome. Lastly, distributed leadership need to be carefully calibrated in a traditionally hierarchical organization to prevent the wrong impression of a laissez- fairer or no leadership approach. By planning forward, distributed leadership can be seed to enhanced specific core competencies skills 3 such as creative thinking, communicating to influence, decision making, develop people and team, developing the individual for success.

Thus the unit needs to be operationally ready to face the continuous complex VI-CA environment. The unit will need to train the men to attain an approved level of technical competence on operating combat engineers’ equipments and honing the analytical functions of the commanders to operating in the various operating conditions.

To meet the demand and influencing the culture, I will take on the leadership by example to be the source of beliefs and values to gradually build a shared assumptions among the commanders and men in the unit. Desired Outcome My desired outcome is to develop an operational, cohesive and discipline unit, which is capable of maintaining safety and achieving mission success in a wide spectrum of operations. The unit should comprises of committed soldiers who are highly proficient in their tasks and proud of their identity as Combat Engineer soldiers.

Accord ing to my MYSELF report and matching the result with the SAFE 24-7 Leadership Framework, I had clearly exhibited a value-based leadership and my strength in the core competency were mission, social and developmental. The results resonated well urine my appointment as Course Commander, with extremely tight training the end-of-course survey, highlighting areas like our instructors’ role modeling, value inculcation, individual development and mission focus. The positive feedbacks were good indications that my instructors understood their roles well and they were given opportunities to develop and lead with my guidance. Socially, I had displayed good interpersonal effectiveness and able to communicate to influence my team well. With strengths, there is also weakness. One of my weakest factor reported was inflexibility of my leadership style. Previously as Course Commander, I was not deeply exposed to the various leadership styles as compared to now in GAS SC. Then, I adopted a more consistent leadership style towards my trainees and my team thinking that a more homogeneous outcome in the inculcation of the SAFE core values was better. 16 Ibid However, I realized this might not be the most effective method to motivate and lead the team. An effective leaders are those who can shift between transactional and transformational leadership styles as required by circumstances and the characteristics of followers†17.

Bacillus Badius free essay sample

Dr. Robert Suran May 1 2013 Microbiology Abstract Over a three week time span I was able to successfully identify an unknown microorganism by combining the results of several tests. The first test was the Gram stain test which showed the microorganism was Gram positive and rod shaped. Using an Unknown Identification Flowchart, I proceeded to inoculate a Starch plate. In week 2, I analyzed the Starch plate and was able to determine that the results for Starch Hydrolysis were negative due to the dark color. Next, I inoculated Simmons Citrate Agar slants. By week 3 I was able to analyze the Citrate Agar, which tested negative for citrate utilization. With each successive test, the list of possible identities was being lessened until I finally came to the conclusion that only one logical microorganism remained; Bacillus badius. Introduction In this experiment I am attempting to identify an unknown microorganism. It is important to identify an unknown microorganism for many reasons, such as, if doctors need to treat an infection they need to first identify the bacteria that is causing the infection in order to know how to kill it. We will write a custom essay sample on Bacillus Badius or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Unknown bacteria may also have clinical uses. For example, Penicillin, which is sometimes used to treat ear infections, is actually isolated from a fungus (Types of antibiotics). Microorganisms are classified based on many characteristics and different microorganisms may share several of these characteristics. Thus, making the possibility of identifying the microorganism, using a single test, none. Over a three week time span I was able to successfully identify the organism Bacillus badius by combining the results of several tests. For majority of the procedures I utilized the septic technique which consists of sanitary measures, such as, washing your hands. I used the Gram Stain test to determine the organisms’ morphology. I also, used the streak plate method for the Starch Hydrolysis Test. Materials and Methods The majority of the procedures for this experiment were performed as detailed for Lab 12, 13, and 14: Identification of an Unknown Microorganism as described in the s pring 2013 BIO 230 Laboratory Manual. Several procedures contributed to successfully determining the identification of the organism. With each successive result, the list of possible organisms lessened. This was done over a three week time span. The first procedure was the Gram stain. Gram staining is a simple test that has four steps: stain with crystal violet, treat with iodine, decolorize with ethanol, counter stain with safranin, and the results will either be positive (dark purple) or negative (pink). In order to do the procedure I heat fixed the unknown bacteria to a slide and positioned the slide in a staining tray. Next, I flooded the slide with crystal violet, letting it stand for 30 seconds and then rinsed it with water. Then, I flooded the smear with Gram’s iodine, letting that sit for 1 minute, before I rinsed it with water. Crystal violet is a basic dye that has a positive charge which attracts the negative charge of Gram’s iodine. The iodine is added and forms a complex with the crystal violet, thus improving the cells retention of the stain. Next, I flooded the slide with ethanol and I let it stand for 15-30 seconds, following with a water rinse. Ethanol dehydrates the peptidoglycan layer which shrinks it; making it impossible for the large crystal violet-iodine complex to penetrate through. Thus, making it trapped in the Gram positive bacteria. On the other hand, the thinner walls make it easier for the crystal violet-iodine complex to be washed out, resulting in the loss of color. Finally, the counter stain, safranin (red dye), is added to the sample by flooding it and letting it stand for 1 minute, staining it red. Finally, I rinsed both sides of the slide with water and blotted it dry with bibulous paper. Because the safranin is lighter than the crystal violet, it does not disturb the dark purple coloration in Gram positive cells. The decolorized Gram negative cells are stained pink. With the results from the Gram stain I was able to follow the â€Å"Unknown Identification Flowchart† to the next step, which was to prepare for the Starch Hydrolysis Test by inoculating a starch plate. Starch is a polysaccharide made up of glucose molecules. Some bacteria have an enzyme called amylase which breaks starch down into glucose subunits. The Starch Hydrolysis test is used to determine the production of amylase. Iodine, which is the mordant used in Gram staining, is used in this test to detect the presence of starch. In order to do the Starch Hydrolysis Test I first inoculated a starch plate by using aseptic technique. I streaked the middle of the starch plate with the bacteria into a single line. Then, I let it incubate overnight at 37 °C. In week 2, after I added several drops of Gram’s iodine to the starch plate it was ready to be analyzed for starch hydrolysis. The iodine complexes with starch to form a blue-black color in the culture. Clear halos surrounding colonies is the result of their ability to digest the starch due to the presence of amylase. With the results of the Starch Hydrolysis Test I preceded to the final test which is the Citrate Test. Using aseptic technique, I streaked the organism onto the surface of the Simmons’ citrate slant and let it incubate overnight at 37 °C. The Citrate Test determines if the organism is able to utilize citrate as its carbon and energy source. The medium contained citrate, ammonium salts, and bromothymol blue (pH indicator). Bromothymol blue is a deep blue color with a pH gt;7. 6. The production of alkaline waste products of citrate metabolism causes the medium to become royal blue which indicates a positive result. If the organism is unable to eat citrate, there will be no alkaline products and the agar will remain green. Results From the Gram stain I was able to determine that the organism was Gram positive and rod shaped. The Starch Hydrolysis test showed no color change to blue-black and no halo appeared. Therefore, the organism was negative for starch utilization. By observing the Simmons’ Citrate slant, which was a green color, I determined the organism tested negative for citrate utilization. With the results of these tests I was able to conclude that the only logical microorganism remaining was Bacillus badius. |Test Done |Description of |Results | | |results | | |Gram Stain |Bacilli rod |+ | |Starch Hydrolysis Dark color |- | | |No halo | | |Citrate |Green |- | | |(no color change) | | Discussion Bacillus badius is a Gram positive and rod shaped bacteria organism which is not able to hydrolyze starch, or utilize citrate as its carbon and energy source.
