РАЗРАБОТКА И НАЗНАЧЕНИЕ ФУНКЦИОНАЛЬНОГО ПИТАНИЯ ПАЦИЕНТАМ, ПОЛЬЗУЮЩИМСЯ ЗУБНЫМИ ПРОТЕЗАМИ

Till present times nutritiology and dietology in dental practice are at rudimentary level. At the same time it is a well-known fact the chewing efficiency is much higher in case of having fixed prosthesis comparing with their removable denture counterpart. As for elderly population nourishment it is important to take into consideration the complexity of receiving of all the necessary nutrients. Quantity and quality of the food diet will directly affect their quality of life.
 Aim. Development of the functional food diet ration for specific groups of dental patients 
 Materials and Methods. We surveyed 244 patients (84 males, 160 females) in the age range from 60 to 85 years (mean value 75.4+/-2.4) with different types of implant supported prostheses. We used clinical, sociological, nutritiological evaluation methods. Besides that we used GOHAI questionnaire and modified Wolfart questionnaire. 
 Results. We defined basic groups of dental patients who have indications for prescribing functional food diet:
 a) patients utilizing removable dentures, especially full dentures, in the situation where antagonists would be intact dentition or dental arches with conventional or implant supported fixed bridges;
 b) patients treated with immediate removable dentures, fixed implant supported prostheses, especially in case of big span bridges with limited amount of fixtures;
 c) patients using removable implant supported overdentures;
 d) Patients older than 70 years of age.
 We established food rations based on intaking soft low viscosity liquid meal. High GOHAI scores (56.1+/-1.49) were the prove of the high efficiency and efficacy of the rehabilitation per se and also of the functional diet regimen recommended to the examined patients.
 Conclusions. We developed functional food diet taking into consideration the short and long term period after finishing the implant supported or conventional, immediate or delayed prosthetic rehabilitation with the use of total prosthesis predominately for edentulous patients. Incorporation of these types of diet regimen in the rehabilitation plan oriented towards increasing the efficiency of the main treatment arrangements.

Surveillance FPV Drone with Obstacle Avoidance System

The unmanned air vehicle (UAV) is mostly used in inspection and surveillance operations recent. The UAV is also termed as vertical take-off landing (VTOL), since it is capable of vertical take-off and landing without need of a runway. The big tunnels, infrastructure and large bridges are inserted using UAV by photographic inspection. UAVs are also used for surveillance purposes by the military and by the security guards. Since this is a new technology of the last decade, deep research has to be done. UAVS have the cross structure arrangement to which the rotor blades are attached at the end points of cross beams. These rotors are driven by the DC brush motors and motors are powered by the lithium ion rechargeable battery. The working principle of quad- rotors is the same as the chopper by controlling the rpm of each rotor blade, due to which the gyroscopic torque will act and the vehicle will move in the desired direction. To hold the quad- rotor at a stationary position at some height constant rpm of all rotors has to be maintained. This signal is given by the controller from some distance, which is received by the, and then it processes the signal and drives the motor via the flight controller and drives the rotors. A quad- rotor is equipped with a high quality camera for photography and video shooting during surveillance. Since a quad rotor is manoeuvring in air, the wind may exert a drag force and take it along with it and the quad rotor may hit any obstacle or inspection objects. To avoid this, it is equipped with the ultrasonic sensors which is capable of sensing the obstacle and realize collision avoidance between wall or any object.

Synthesis, microstructural, corrosion and antimicrobial properties of Zn and Zn–Al coatings

ABSTRACTDevelopment of a new coating named ‘Zincal’ is introduced for future smart cities’ infrastructures. Pure Zn and newly developed ‘Zincal’ (a composition of Zn–Al) thermal sprayed (TS) coatings were applied onto low-carbon steel to investigate coating’s life against the corrosive and dusty environment for future smart cities’ infrastructures (big bridges, buildings, poles, stadiums, railway structures etc.). Therefore, for both coatings, salt spray humidity and microbial tests were carried out. The result shows that Zincal coating has promising anti-corrosion properties under combat microbiological corrosion attack and is also suitable in the humid and salt containing environment.

Image processing of alos palsar satellite data, small unmanned aerial vehicle (UAV), and field measurement of land deformation

Pekanbaru, Indonesia is connected by four big bridges, Siak Bridge; I, II, III and IV. The quality of the Siak bridges deteriorated seriously at this time. Geological mapping for the land subsidence potency was conducted using small Unmanned Aerial Vehicle (UAV) in the Siak Bridge areas. The study of the Siak bridges are supported by the Differential Interferometric Synthetic Aperture Radar (DInSAR) analysis using ALOS PALSAR satellite data, and the deflection observation that occurs in Siak III Bridge was observed by field measurement. The results of 3D model analysis showed that there is no negative land deformation. DInSAR analysis shows the amount of positive deformation of Siak I is 81 cm, Siak II is 48 cm, Siak III is 89 cm, and Siak IV is 92. Deflection on Siak III Bridge was detected at around 25-26 cm. These models could be used as a new way of measuring the bridge deformation on a big scale.

Soil Classification and Seismic Site Response Analysis for Some Areas in Hanoi City

Abstract: Along with the development of urban and modern life, Hanoi Capital has been constructing more and more sky buildings, big bridges and huge underground constructions. According to historical studies, Hanoi is a region located on the weak soil ground which has a rather thick sedimentary layer, complicated geology structure and shallow ground water aged in the Holocene and Pleistocene. Hanoi city is cut through by a Red River fault which has been considered to be a strong active fault zone. As a consequence, it is able to cause earthquakes with magnitude M = 6.1 corresponding to the 7th ground vibration level in intensity. In order to predict the casualty of this severe earthquake being able to happen, it is surely essential to assess both seismic site response and geological conditions in Hanoi. In the paper, we will analyze the soil ground data and borehole data obtained in this region to find the specific geological factors which are put into the DeepSoil Program to evaluate local site effects.

An Autobiography of the Doctor’s Son in a Shipbuilding Town

An Autobiography of the Doctor’s Son in a Shipbuilding Town Matthew Clark (bio) The cowboy beside me at the Wyoming bar stared like a buffalo and I too tried out this stare, but the dingy mirror failed to reflect me—a mystery, I thought, considering that to show you your own soul, as a mirror cannot do, artists embalm sharks and flush urinals and crucify Jesus upon a penis. Art, they say, is a special kind of mirror. The bar’s was spectacularly fractured. Lines vectored from an ancient bullet hole, knifing the low winter light. It was beautiful, but I watched the television above, projecting football. A record iii million other people were staring too, including my retired father, watching from a couch beside the Kennebec River, yelling out the score, muting the sound of ads to more easily concentrate on his reading of the New York Review of Books, shelling unsalted peanuts, drinking a dark, stout, grown-up beer. I drank my hypoglycemic pint quickly and ordered another. The run from my childhood home had left me parched. I’d been running steadily for 10, maybe 20 years and was by now at a pretty good remove from Maine, where my older brother and I, pretending our hammocks were horses, swung between birches, robbing banks and tomahawking Indians and collecting the scalps of cowboys like the one sitting beside me. Even his wet lips had cracks like fast dried mud. He could have hung on the walls where a stuffed and dusty and bejewelled West presided. The heads of ungulates, bears, lions. Guns and pickaxes and nooses. Wanted posters. Billy was wanted. I’d been a sharp kid, I told the cowboy, just making small talk. When I made patterns [End Page 55] with my pattern blocks, I was exceedingly proud to have my father bestow that word, “sharp,” upon me and as cleverly as one can only be in dreams, I smashed my exhausted pint glass, lifted the unlistening cowboy’s big brim and, with a keen shard, jettisoned the top off his skull. He didn’t even flinch. He took another gulp. His lips shone and his brain glowed gold. When he touched his hat, I attempted to ape the gesture, but failed, being, as I was, hatless. As a kid, to possess a brimmed polka dot cap like the shipbuilders wore had been a tingling fantasy. My dad had a sort of purple velvet French beret with bells and yellow stars. I had given it to him and when he donned it he became an invincible magician, an orchestrator of disappearances and appearances on the scale of the 17,000-ton all-steel Aegis destroyer, the vessel built in the windowless warehouses stretching further than I could run along the streets and the river. Inside the warehouses were the hatted men. But what were they doing, exactly? What did men do? I don’t know. I never went in. I never saw. My father, the doctor, was adamant about weeds. He paid one cent for every invasive I dug from the lawn, though only if the pale carrot root was intact. If you didn’t get the root, you didn’t get the weed, he said. Sometimes my friends dug with me. My father, gin and tonic in hand, would count out the weeds in our buckets and count out the change in his pocket. Then we rode our bikes to town and bought oil for our chains and Blizzards from Dairy Queen and then we biked across the big bridge to watch the pennant-fluttering launch. Except for the towering red, white, and blue cranes topped with lit trees at Christmas, shipbuilding happened invisibly. It was miraculous when the sharp ships, arrayed with the lines of suited men at attention, bristling with guns and radar and unnamed spiked technologies, rolled slowly into the river. We went mad with cheering and managed to cartwheel from the bridge and into the Kennebec where we treaded water until the incoming tide floated us upriver to my house. There we emerged from the slow brackish flow, turned, whooped, and dove back in, scattering the reflections of the...

Work Mechanisms of Pile Foundation in the Karst Region

The stability and deformation characteristics of the pile foundation in the Karst region of the super big railway bridge Chaogou under different loading levels are analyzed using the FDM-software, FLAC3D. In the analyses the socketed depth of piles, the properties of soil and rock mass, the scale, space position and filling situation of the Karst caves and the features of the contact interfaces between piles and soil and rock mass were taken into account. The research results show that the original design of the pile foundation is safe and the safety coefficient is greater than 2. The bond strength of the contact surface between pile and soil and rock is a controlling factor for the stability of pile foundation. Therefore, injection after construction is suggested to be used when needed, in order to increase the bond strength of the contact surface. The research leads to a conclusion that the mechanisms and the characteristics of the rock socketed piles can be more clearly interpreted in numerical analyses by referring the principle of the interaction between piles and rock, pile foundation and Karst, resistance of both pile ends and sides.

Analyze on Construction Status Long-Span Arch Rib Bridge by Numerical Simulation

Non-cable hoisting frame is a construction method of the main arch ribs of big span bridge. The key issue in the numerical simulation of this type of bridge construction is geometric nonlinearity approach. Construction method of long-span bridge rib and stage-by-stage construction method of a arch bridge was simulated by finite element method. The geometric description was attained comparison with simulation results and the actual measurement of cable force. The results show that finite element method is effectively used in the simulation of long span arch bridge construction.

Home-Based Family Therapy: An Illustration of Clinical Work with a Liberian Refugee

In this paper the author provides a case illustration of home-based systemic therapy performed in the U.S., with a female survivor from a war-affected region of West Africa. Providing clinical services in a person’s home has been shown to be an effective way to engage those who are otherwise unlikely to seek out mental health services. In this paper, first-person narrative vignettes about the therapy endeavor illustrate how working in the context of the client’s home assisted the clinician in eliciting rich information about the resourcefulness of the client in constructing a new life for herself in her host country. Such information tends to be overlooked in literature about work with refugee survivors of war. Every Friday at 10 a.m., I travel to West Africa. I drive one hour from my suburban neighborhood, down city streets, across the big bridge, and through neighborhoods I never have reason to visit otherwise. When I arrive at my destination, 45 minutes after I’ve begun, I am at an apartment building with a distinct 1970s look to it. Parking my car neatly in a tiny guest spot near the office, I walk to the second floor of a building adjacent to the apartment office. Outside her door, I knock, and a few minutes pass before a smiling, well-coiffed young woman, Veronique, 1 welcomes me inside. For the next hour I will be a guest in her home, her personal representation of a small piece of Liberia, West Africa, transplanted to a living room in the U.S.

Japan–Bangladesh Relations

This article studies the nature of relationship between Japan and Bangladesh focusing mainly on the Japanese Overseas Development Assistance (ODA) policy for developing countries such as Bangladesh. It also covers trade and other related issues that shape the bilateral relations of these two countries in a historical perspective. This is an interesting study as Bangladesh has consistently been a major recipient of Japanese aid and assistance for a long time in various areas of crucial importance for Bangladesh's development ranging from education, health, rural development, power plant development, private sector development, urban waste management, infrastructure development like building big bridges over mighty rivers, water supply in major cities, good governance and democratization projects. Japan is a great economic power and also regarded as an ‘aid great power’ but not a military superpower, thus, what determines its economic assistance policy and relations with a country like Bangladesh in South Asia is the central theme of this paper. Cultural relations between Japan and Bangladesh even go beyond the recent diplomatic history. Both the countries are culturally homogenous, natural disaster prone and scarce natural resource nations and Japan is the only country outside of the western world to be able to develop at par with the western countries while practicing democracy simultaneously. From all these points of view Japan can be considered as an ideal development model for Bangladesh.

淀川本支川の農薬の流出特性と流出リスクの評価

The runoff characteristics of pesticides were observed every three days for four months in the Yodo River and its two tributaries, and monthly for their traverse distributions in the Yodo River while flowing down from the junction of the upper three big rivers to the Torikai Big Bridge. Simultaneous rice transplanting and subsequent application of pesticides in catchments caused high concentrations and loadings of pesticides. When the first-half stage of storm runoff events after pesticide application was observed, the concentrations and loadings of pesticides in the river were very high. The concentration peaks of pesticides were lower and broader in the Yodo River than in its tributaries due to the time lag in local pesticide application in its big catchment area. The peak times and heights of many pesticide concentrations on the right and left sides, and in the center in the traverse section of the Yodo River differed from one another owing to their differences among the three big upstream rivers and small midstream tributaries. The frequency distributions of pesticide concentrations in the fixed observation period became the logarithmic normal distributions due to many unditected low values. The runoff risks of pesticides in the rivers could be evaluated by the maximum concentration, ΣC·ΣT, cumulative loading per catchment area, and cumulative ditected concentration.

Steel bridge construction in Japan

Abstract This paper briefly introduces the recent steel cable-stayed and suspension bridge construction in Japan. The big bridge projects in the highway network construction of the bay-shore routes in the Tokyo Bay, the Osaka Bay and the Ise Bay along the Pacific Ocean side are described. The Seto-Ohashi Bridge Route of 13·1 km, which skips five islands of the Inland Sea between Honshu and Shikoku, was opened in April, 1988. The Akashi-Kaikyo suspension bridge (960 + 1990 + 960 m) is now under construction and will be completed in 1998. The Trans-Tokyo Bay high-way project, which includes a total length of 5-km steel box girder bridges, is under construction, and the Kansai International Airport project is under progress in the Osaka Bay with 5-km truss-type access bridges for highways and railways. Steel consumption in bridge construction and steel bridge stock is also mentioned.
