Gilbert Paterson Junior High Lethbridae. AlbertaVALEDICTORY by Reva Storfie
To us, 1956-5? graduates of the Gilbert Paterson Junior High School, the term '‘graduating" means far more than a movement from Junior High to the realm of High School. Graduation is the portal to an intricate and ever changing world, which, particularly today, demands from each of us advanced knowledge and understanding much beyond that which we possess now. In this modern era, the value of education far exceeds the value of material things. And, upon this belief, we base our goals, standards and values. Passed down from teachers and parents have been the high standards which we hope to uphold for all times. Nov; has come the time not only to think about values, but to put those beliefs into effect.
For nine well planned years of our lives, we have attended classes at both the elementary and Junior High School levels. Each year precise information was gathered and added to the fund of knowledge gained in previous years. As the years progressed, we learned to be less dependent of others. Through guidance, came the time when we were even able to answer some of our own questions. The most cherished of all years, have been the two event-filled years at Paterson. As Paterson's second graduating class, we have often worked diligently and attained satisfaction in our many and varied courses of study. Now, after these nine school years, we are prepared to advance to the higher grades, and we find that our education is just beginning a new phase.
But, looking back, we find Paterson Junior High has given us many things with which to face the future years. First of all, wisdom, in being able to realize what a necessity a good education is.
Secondly, through extra curricular activities, which this school has many, the ability to cooperate with others, and thirdly, the ability to appreciate fully the people associated with our school.
As we, presently Grade Nine students, and tomorrow’s citizens, approach the end of a most rewarding and personally satisfying
Junior High School career, we feel both happiness and regrets--
Happiness, for being allowed to share in a newer perspective of learning at High School, and regrets, in leaving behind a school where many memorable events have taken place, and where such understanding teachers have given us so much of learning and the dignity of learning.
So, it is with deep gratitude we say farewell to a school we will never forget--our Gilbert Paterson Junior High.This Yearbook is dedicated to our friend and benefactor, Mr. Gilbert Paterson, Q. C.
'lTC THE STUDENT BODY OF 1956-57
You are about to finish another year of your school lire.
It is my sincere hope that this school year has been a successful one to you in many ways. I hope that you have made some orogress in learning, that you have gained greater ability to use your knowledge and that you have had a happy and enjoyable time in doing this.
Here are a few thoughts I would like to leave with you. Education is a never-ending process. You must continue to learn as long as you live.
"Not enjoyment, and not sorrow,
Is our destined end or way;
But to act, that each to-morrow Brings us farther than to-day".
The world you live in is constantly changing. If you wi4h to succeed, you must change - you must be able to adapt yourself to your changing environment.
Take a certain measure of care in your choice of friends. "True happiness consists not in the multitude of friends, but in their worth and choice".
You should try to overcome your own faults, and you will have less time to criticize the faults of others.
Remember that your conduct is about three-fourths of your life and its largest concern.
You should endeavor to be true to yourself - to your sense of right and wrong. Mark Twain once said, "Truth is the most valuable thing we have. Let us economize it".
If in some way you would endeavor to follow the above things, I am sure that you would be successful in life; you would have the respect and esteem of those with whom you come in contact; and above all, you would have an inner feeling of self-respect and well-being.JUNIOR HIGH STAFF

GILBERT PATERSON HOMS & SCHOOL ^SOCIATICN
i
At the end of the second year of operation, the Gilbert Paterson Home and School Association feels that some progress has been made in being of service to the School, the parents and the students. The Grade IX Graduation Banquet was again sponsored by the Home & School, and a substantial start was made on a dinner set for the school. Home & School Scholarships were set up, through which we hope to encourage more of the students to higher academic standars. A most interesting art display cf Jeffrie’s Historical drawings was brought to the school for a week and was used by a majority of the students.
V/e hope each year to increase our activities and become of more value to the School and the Community.

Zelma KelsonA SUCCESSFUL YEAR
The council feels that the activities for the school year 1956-57 have been very successful.
During the year many students took part in two successful skating parties.
Last fall we held a Welcome Home Dance inviting back last year’s graduating class.
We held four other successful dances, The Opening Dance,
The Christmas Dance, The Valentine Dance, and the Easter Bunny Hop.
The students' Union took part in the fund drive for Hungarian
Relief.
We conducted again a Turkey Raffle which netted a substantial sum of money for the treasury.
V'e purchased for the Year Book Staff a flash camera to take candid shots for the 56-57 edition of the yearbook.
We decided to purchase for the school a tape recorder to be used in our class rooms.
We instituted for the first time "The Color Day" at which time we presented awards to meriting students.
At the scholarship presentation were included our Student Union prizes for academic achievement.
We purchased a House Trophy won most consecutively by House Alpha this year.
We held a series of Lits, the Grade Seven Spelling Bee, the Grade Eight Quiz Contest, and for the first time, the Grade Nine Interhouse Debates.
We hope that we have served you well and that you found this year one of the best years in your school life.

The Purge of 209
This is the school. In this school are three hundred pupils. Some are good, some are bad. 3ut they have one thing in common. They're here to learnl That's where I come in. I’m a teacher.
It's ten to nine, the students are beginning to come in. I study them carefully looking for concealed weapons. In the meantime a fellow teacher is already at work. Elgin 'Veils, Wes Stefan, Cathy Hay, Jack Downie, and Lorraine Lyons are picked up on a 612, loitering in the halls.
Nine o'clock. Everything is quiet. I open the book and begin to read. Cut of the- corner of my eye I see several doing last nights homework. They have a worried expression. We've caught them off guard for once. It looks like a nice morning.
Nine o five. The bell rings and the students move. The
minute they are out of the room I gt> to work. Hob Adams, Gary
Douglas, John Hold and Bill Leedam are picked up on a 480. They were firing spitballs at the students from 210. They'll get the blackboard for that.
Nine o Nine. The students are in social, Lorallee Hall, and
Carol Patey are caught in 8101, note passing. V.f. Aoki is really
on the ball. He is ready for any trick as he deposits pearlly words of wisdom into their minds.
The class moves. Eda Seaman is picked up on a 113740, a very serious charge. Obstructing traffic.
They're in math. Pred Anderson, Brian McKelgunn and Sylvia Stevens are booked on a 1150. Math homework not done. They'll get hard labour for that!
Class again moves. Larry Ogden is picked up on a 680. He held his books so high that falling objects became dangerous to some of the smaller teachers.
Class moves to typing. Garden Bennett and Lyn Vright are booked on £ 650 and 430, flying planes which have not been approved by CCA and flying without a pilots license respectively.
Class moves, Cynthia Lambert, and Hose Lepp are picked up on a 319 gum chewing.Literature class, I get Judy Rhamey, Donna Workman and Mildred Spencer on a 207. Everyone knows thats Tor talking. Arlene Williams is trooped on an 810 for note nassing, as I strive to enlighten the Dupils on the matter of literature.
The bell rings. As they leave Beatrice Lewis and Olga Bankonin are nicked up on general principals. They haven't done anything yet which makes us suspicious.
1 get out my file and go merrily to work on my bicuspids as the students leave. From the looks we are poor misunderstood teachers, yet you would think we weren't humans.
The ideas expressed here are not necessarily the ideas of the student bodyl They are merely the ideas of the minor majority called 209.
In conclusion I would like to thank Miss Toole of the yearbook staff who, by the time you read this, has undoubtedly censored half of this, the School Board, who supplied ink and paper, and Beatrice Lewis without whose constant reminders of the delivery date I could not have possibly gotten this done.
Yours truly,
Elgin ’.Veils.

Developing Resource Usage Service in WLCG
No full textAccording to the Memorandum of Understanding (MoU) of the World-wide LHC Computing Grid (WLCG) project, participating sites are required to provide resource usage or accounting data to the Grid Operational Centre (GOC) to enrich the understanding of how shared resources are used, and to provide information for improving the effectiveness of resource allocation. As a multi-grid environment, the accounting process of WLCG is currently enabled by four accounting systems, each of which was developed independently by constituent grid projects. These accounting systems were designed and implemented based on project-specific local understanding of requirements, and therefore lack interoperability. In order to automate the accounting process in WLCG, three transportation methods are being introduced for streaming accounting data metered by heterogeneous accounting systems into GOC at Rutherford Appleton Laboratory (RAL) in the UK, where accounting data are aggregated and accumulated throughout the year. These transportation methods, however, were introduced on a per accounting-system basis, i.e. targeting at a particular accounting system, making them hard to reuse and customize to new requirements. This paper presents the design of WLCG-RUS system, a standards-compatible solution providing a consistent process for streaming resource usage data across various accounting systems, while ensuring interoperability, portability, and customization

Interacting artificial surf reefs
No full textWave surfing is existing and becoming more attractive in the Netherlands. However natural wave conditions are not suited to encourage the sport. To improve the surf conditions of the local waves, Artificial Surf Reefs are potential solutions. As a part of intentions to optimise the design of Artificial Surf Reefs, this thesis is aimed at gaining insight into the wave-induced circulations and the wave-current interactions around an artificial reef. Impacts of the channel width on these processes were assessed by varying the width of the channel. Several surf-ability parameters were measured or observed to verify the performance of the proposed design. The surface currents on either side of the reef show a decrease in intensities and dimensions resulting in less intense wave-current interactions around the structure. It was found that rip currents with a Froude number smaller than 0.1 do not cause negative impact on the breaker shapes.Civil Engineering and Geoscience
袁桷作品對琴史的總體貢獻
No full textYuan Jue (1266-1327), courtesy name Bochang, pseudonym Qing Rong Jushi (Retired Scholar of Refined Demeanor), was one of the most distinguished scholars during Yuan dynasty, his biography record can be found in the 172nd chapter of the official biographies in the History of Yuan Dynasty. To understand Yuan Jue’s knowledge of Qin, is possible to refer to some of his works concerning different aspects of Qin tablatures, schools, masters of the Northern and Southern Song periods. Yuan Jue makes some special remarks on the original source of some melodies played during his own time, pointing out the effective contributions of some of the most relevant Qin masters during Southern Song Dynasty in the formation of the so-called Zhe School, underlining his doubts and believes, especially over master Yang Zuan, the author the Zi Xia Dong tablatures (now lost). According to Yuan Jue, some of the melodies collected in the Zi Xia Dong pu where not made Yang Zuan himself: after some comparisons, he discovered that the Cai Shi wunong (Five melodies by Cai [Yong]) were mostly identical to the same tablature transmitted by Zhang Yan from Southern Song Dynasty. The famous Qin player Guo Chuwang has been a hanger-on of Zhang Yan’s household; after receiving the tablatures collected by Zhang himself, he underwent a further reassembling and passed them down to later generations, till Yuan Jue’s days. Yuan Jue displays deep respect towards Zhang Yan and Guo Chuwang contributions (Yuan Jue also wrote two poems on Qin melodies written by Guo Chuwang), and the main aim of his texts on Qin is evidently to clarify and attest the real importance and influence of his past masters
Mineral nutrition of oxygen-stressed crops and its relationship to some physiological responses (Chapter 35)
No full textHistorically nutritional studies of anoxic plants have simply
catalogued concentration and uptake changes of treated plants,
frequently on a non-partitioned whole-plant basis. Major reviews of
soil aeration and flooding generally agree that N, P, and K
concentrations in plants are reduced by anoxia (Kozlowski, 1984;
Glinski and Stepniewski, 1985). Sodium concentration increases and
other major elements either remain unaffected or react irregularly.
Until recent years explanations of nutritional changes have focused
chiefly on alterations in the poorly aerated soil physicochemical
environment. Factors such as: increased mineral solubilization,
leaching, and dilution in high water content soils, increased water
film coverage of roots, altered ion diffusion, solubility changes at
altered valence states, altered pH resulting from redox reactions
or increased CO2 concentrations, etc. have been used to explain
nutritional responses to oxygen-limiting soil environments
Overtopping on Grass Covered Dikes: Resistance and Failure of the Inner Slopes
No full textA large part of the Vietnamese population is living close to the coast. The sea is an essential source for supporting lives. Coastal flooding, on the other hand, threatens the people, land and infrastructures every year. Some hundreds years ago, the first sea dikes were built in Thai Binh and Nam Dinh provinces. In the north, the coastline is now protected with more than 700 km of estuary and sea dikes. Being directly exposed to waves and currents, these dikes must be sufficiently stable and durable to function as coastal defences. The present thesis contributes to better understand how a dike performs under overtopping during a storm surge. The research limits itself to a slope that is covered with grass on the landward side. Therefore, this slope is mainly attacked by the overtopping flows. The research mainly explores four issues concerning a) damage pattern of grass dike slopes in Vietnam, b) how to quantify overtopping flows, c) how roots strengthen soil within a grass cover and d) classify and model damage to slopes due to overtopping. First, a wave overtopping simulator was used to test the strength of some grass covered slopes in Vietnam. The simulator was designed to generate overtopping flows at real dikes in normal weather conditions. The tested slopes could withstand a mean discharge varying from 20 to 100 l/s per metre of dike length during several hours. Damage usually starts at bare spots, at the inner toe, at the transition between different materials, and around objects (e.g., big trees). These features reduce the strength of a dike slope and therefore should be avoided as much as possible. Second, the thesis established formulas to quantitatively estimate overtopping flows. To this end, the research re-analysed an available set of data. The flow velocity and the water-layer thickness are related to the corresponding run-up level and overtopping volume. Within their ranges of application, the formulas can predict the flows in front of the simulator and on the dike slope relatively well. Third, the thesis investigated how roots strengthen soil on Vietnamese dike slopes. Measurements were carried out with four grasses Bermuda, Carpet, Ray and Vetiver to determine the diameter, the volume, the weight and the number of roots; and how strong they are. About 60 to 80% of roots have a diameter varying between 0.1 to 0.2mm. The volume, the weight are proportional to the number regardless of the size. About 60 to 90% of the root amount are present within the top 10 cm under the soil surface. There are less than 10% under 20 cm. A root thread can resist a pulling force of several Newton and this value often increases when grass becomes older. Formulas are developed to estimate the reinforcement to soil where roots are embedded in. The soil strength depends directly on the number (density) and the strength of roots. Fourth, the findings achieved earlier are integrated to investigate how a grass covered slope behaves when being attacked by overtopping flows. Based on the observations with the simulator tests, damage is classified into different manners depending on grass, material components and corresponding layer thickness. Erosion usually starts at weak spots so the thesis examined their spatial distribution along a dike stretch. The resistance of a grass cover can be estimated with two approaches. The first one assumes a critical velocity depending on the soil cohesion and the apparent cohesion induced by roots. The cover is damaged when the flow velocity exceeds the critical value. The second one solely considers a total tensile strength produced by the intact roots. The flows exert force to gradually break root by root, and the Root Bundle Model was developed to assess this process. Calculations show that older grass with a greater density and stronger threads of roots increases the resistance. By addressing these four issues above, the thesis has achieved its main research objective. By and large, it provides more profound insights into the damage of a grass covered slope due to overtopping. Besides, the study proves the potential strength of grass in protecting a dike slope. This strength would increase proportionally to the development of grass. Notably, a mean discharge appears to indicate partly the destructive effect of overtopping. Therefore, one should be aware of the simplification when using this value to design and appraise a sea dike. Last but not least, high dikes with no overtopping are expensive to obtain in developing countries like Vietnam due to the budgetary constraints. As a matter of fact, sea dikes might be lower and therefore cheaper when certain rates of water are allowed by taking into account the resistance of the applied grass.Hydraulic EngineeringCivil Engineering and Geoscience
