    Ground improvement using fibredrain (FD) material has not been used in Japan. For its practical use in Japan, laboratory experiment was made on such technological characteristics of FD material as tensile strength and permeability, and field test was also made to verify its improvement effect. A plane FD specimen of nearly 90mm wide and 9mm thick is composed of a folded double jute fabrics band and 4 twisted coir ropes arranged between the jute fabrics at even intervals, and the band is sewn up along center lines between the ropes. A mean permeability coefficient is estimated to be {kappa} = 1.0times10{sup -1}cm/s and {kappa} = 1.0times10{sup -2}cm/s at {sigma}{sup 3} = 0.5kgf/cm{sup 2} and {sigma}{sup 3} = 2.0kgf/cm{sup 2} in lateral pressure, respectively, showing sufficient permeabilities for vertical drain material. The tensile strength of fresh FD material is estimated to be a little stronger than 900kg/material width which is far stronger than that of conventional FD materials. The field test result showed that the FD material achieved the target for ground improvement, and has sufficient functions as a substitute for SD material. 6 refs., 10 figs.

    To reduce the construction period and cost and to enhance the safety during 77 kV-class transmission tower election, a new method of small steel transmission tower erection using an external type crane has been developed. For the selection of cranes, a commercially available self-climbing crane was employed which has an operating radius of 11 m, a lifting load capacity of 1.5 t, and a lift of up to 60 m. For the space analysis using a model tower, various supporting methods with horizontal supporting members, stress analysis for each tower stub, and apparatuses were examined. For the demonstration tests of election using the model tower, strain gages were attached at each point of steel tower, crane and horizontal supporting members, to measure the stress of members at each stage of the election. It was confirmed that there were no problems. For the election of actual steel tower, the practicality of this method was compared with that of conventional methods. The construction period was reduced in 20%, and the cost was reduced in 4%. The safety of this method was drastically enhanced due to the lack of moving on the tower and less manual operation. 9 figs., 1 tab.

  5. Zn/gelled 6 M KOH/O 2 zinc-air battery (United States)

    Mohamad, A. A.

    The gel electrolyte for the zinc-air cell was prepared by mixing hydroponics gel with a 6 M potassium hydroxide aqueous solution. The self-discharge of cells was characterized by measuring the open-circuit voltage. The effect of a discharge rate of 50 mA constant current on cell voltage and plateau hour, as well as the voltage-current and current density-power density were measured and analysed. The electrode degradation after discharge cycling was characterized by structural and surface methods. The oxidation of the electrode surface further blocked the utilization of the Zn anode and was identified as a cause for the failure of the cell.

    Technology is discussed of detecting structures buried in the ground by use of a forward-looking sensor mounted on the drill head for the avoidance of collision with such structures during application of the flowmole method in urban districts. In this detection system, pulsating radio signals are emitted from a transmission antenna and the received signals are converted into low-frequency signals in a sampling circuit for eventual display on a B-scope. Since the drill head for flowmole technology is as small as approximately 50-60mm in diameter, experiment is conducted to know the detectability of a very small antenna directed at a buried pipe. The basic phase of the experiment using the very small antenna includes a soil-filled tank test and field test. It is then found that the very small antenna is capable of detecting the steel pipe buried 50cm away from the antenna with the antenna directed at the said pipe. In a test wherein a very small antenna is allowed to rotate on the drill propelling shaft, the design simulating a revolving drill head, it is learned that the detecting system under study will identify the direction in which a buried structure exists. 1 ref., 9 figs.

    For the construction works of underground tunnels, mainly the shield method has so far been adopted, but in order to make underground junction of shield machines, the method of utilizing a shaft or the method of improving the earth by the auxiliary methods such as chemical feeding have been adopted. However, either method has restriction for its practical application. The MSD method uses no auxiliary method at all, can join directly two shield machines mechanically underground, has high water stoppability at its junction, is applicable for either of shield machines of slush type or mud pressure type, and is the method to solve totally various problems in the existing joining methods. This method is the one that two shield machines, one on the out-pushing side and another on the in-receiving side, progress from both sides and face each other, then the both are joined mechanically for unification by pushing a steel penetration ring built-in the out-pushing shield machine to the rubber ring built-in the penetration chamber of the in-receiving shield machine. After joining, the shield machines are disassembled for removal leaving the junction only, and the secondary lining is done with concrete. 6 figs.

    Frequently used airports do not allow the period during which facilities are shutdown for cultivation in the repair work of sunk concrete pavement. The present report describes the outline of the lift-up construction method by means of prestressed concrete pavement which allows repair work only in the night. The method has been developed and demonstrated this time in the construction of off-shore development of Tokyo International Airport. The fundamental procedures are as follows: A [phi] 16cm hole is drilled with a core boring machine into the pavement slab in the sunk area; the roadbed is excavated around the hole in the volume of ca. 45cm in diameter and ca. 30cm in thickness; a reaction bed of concrete and a metal fixture of the hydraulic jack are installed; the reaction bed is exerted with a force by the jack to lift up the pavement slab; and finally the gap made between the pavement slab and the road bed is grouted with cement milk. In a demonstration test construction, lift-up of 3.5cm over ca. 3500m[sup 2] was performed during a total of four days of one day in the daytime and three days in the night. 7 figs.

    Minami, K.; Matsui, H.; Naruse, E.; Kitazume, M. [Port and Harbour Research Inst., Kanagawa (Japan)


    This paper describes the sand compaction pile (SCP) method using copper slag sand. The SCP method is a method by which sand compaction piles are constructed in the ground, and improvement can be obtained in a short period. This method has been widely used even in the port areas for enhancing the bearing power of soft clay ground and the lateral resistance of sheet pile. A great deal of sand is required as a material. The sand requires high permeability, proper size distribution with less fine particle fraction content, easy compaction property with enough strength, and easy discharging property from the casing of construction machines as required properties. Recently, it becomes hard to secure proper sand materials. The copper slag sand is obtained from refining process of copper as a by-product which is quenched in water flow and crushed in water. The copper slag sand has higher particle density than that of sand, excellent permeability, and similar size distribution to that of sand. From compaction drainage triaxial compression test and permeability test, it was found that the mechanical properties of copper slag sand did not change by the crushing of grains with keeping excellent permeability. Through the test construction, applicability of the copper slag sand to the SCP method could be confirmed as an alternate material of sand. 17 refs., 9 figs., 4 tabs.

    This paper describes a rectangular section shield tunneling method as a part of developments of non-circular section shield tunneling methods. The non-circular shield is drawing attention because of need of excavation in small land available in urban areas and between congested existing structures, as well as reduction in the excavated soil amount. A full-scale machine was fabricated to perform a natural ground excavation experiment. The cutter units comprising two each of drum cutters and ring cutters were arranged above and below, by which two tunnels of 40 m long with a cross section of 2.85 m {times} 2.85 m were excavated. The natural ground was supported safely by holding mud water pressures at cutting points constant, thus stability of the cutting points was ensured. Back-filling has made complete filling of tail void (clearance between a segment and the ground) possible, resulting in suppression in conditional change of the surrounding ground. Attitude control has been performed properly as a result of correct selection of shield jacks and use of deflection jacks. Broken-type over-cutters were used to have constructed tunnels with curve radius of 80 and 100 m with high accuracy. Thrust and propulsion speed of the shield do not differ from those of circular shields. Possibilities of this construction method were verified. 8 refs., 26 figs., 2 tabs.

    Progress of development in latest shield construction method is startling. Various new construction methods have been developed and applied to constructions, such as a triad multi-shield, a parent-child shield and variable cross section shields for multi micro shield tunnel and square cross section, including a spherical shield. On the other hand, large and long-distance shield constructions have been carried out, such as ones for the Tokyo Bay Highway and Kanda River, which have inevitably accelerated development of automation. Different systems that have been completed, developed and applied to actual constructions include systems for automatic segment transportation and assembling, automatic extension of mud delivery and drainage pipes, automatic excavation control, sheet spreading devices, and comprehensive construction control. Recent constructions tend to require high-speed excavation and work at greater depths, in addition to increase in scale and distance, whereas developed new technologies are increasing diversity. This paper lists in one table new technologies for shield construction methods published in the last decade. It also summarizes representative technologies extracted from the table, looks back over the new technologies used in the Tokyo Bay Highway construction, and describes future prospects on the technologies. 9 refs., 5 figs., 2 tabs.

    This paper describes the development of a reinforcing method for reinforced concrete (hereinafter RC) structures by using carbon fibers (hereinafter CF). This developed method attaches a light-weight CFUD prepreg material for reinforcement by laterally winding CF strand impregnated with epoxy resin, which is hardened under normal temperature. This method is economical because no skills and special tools are required. An RC pillar with circular cross section and a hollow RC test body assuming a chimney were used as models. The paper details the experiment. This method has been used in several ten existing RC stacks with effective reinforcing result. Resistance strengths of CF strands and UD prepregs were verified in an accelerated exposure test performed according to JIS A 1415, standard for plastic building materials. The effects of the anti-seismic reinforcement have resulted in improvement in shear resistance force in RC pillars by means of CF winding method, improvement in bending stress in RC structures as a result of CF attaching method, and effectiveness in repair of existing RC stacks. Sufficient exposure resistance has also been proved. A bending test by means of two-point concentrated loading has been performed as a weighted test. 4 figs.

    A freezing carrier is a dedication ship to transport frozen and refrigerated cargoes such as foodstuffs loaded in holds. Ship's heat preventing devices must have the heat insulating structure formed according to complex shapes characteristic to an ocean vessel, and the most part of the work is done by skilled technicians working on the site. Therefore, discussions have been given on a heat preventing structure using a panel construction method aiming at simplifying cross sections to more efficient and uniform shapes, and hold shapes and work in them to more suitable for palletized packaging styles, and improving working environments. The results of the discussions have been applied to two ships for the first time, and the effects have been verified. This paper reports its specifications and construction. The heat preventing panel is a sandwiched composite of a surface material and a polyurethane foam, made to a panel size of about 1 m [times] 2 m. Joints are fixed by fasteners. The present ships have adopted such a form that the side walls are vertical, but the floor area and the clear height are the same as the conventional construction methods. Good heat insulation performance and workability have been verified, and results that are expected of further development have been obtained. 7 figs.

    As an electric power supply source after the 1990 {prime}s, Nos. 5 and 6 units are additionally being constructed by Kansai Electric Power in its Himeji Power Station No.1 which is an exclusively LNG burning power station. The additional construction site of those units is of soil foundation reclaimed with coal ash which was used residual product in the existing No.1 through No.4 units. As a result of soil foundation survey, the coal ash layer and sand layer were known to be of material to be possibly liquidized at the time of earthquake. As measures against the liquidization, application was basically made of a sand compaction pile (SCP) method which is economical and abundant in record. However, that method was so short of record in the coal ash layer that its evaluation was difficult in soil reforming effect. Therefore, its applicability was evaluated by a work test on the site, which resulted in a confirmation that the coal ash as well as the sand can be sufficiently reformed by the SCP method. Started in September, 1991, the additional construction of Nos. 5 and 6 units in Himeji Power Station No.1 uses a 1.5m pitch SCP method to reform the soil foundation. 3 refs., 10 figs., 1 tab.

    Temperature and humidity characteristics and condensation within walls under heating and humidification were studied experimentally in winter using two test houses of conventional and ventilated structures. The absolute humidity in conventional one fluctuated depending on temperature gradient, water flux due to humidification and water adsorption onto glass wool, and accumulated water increased with humidification. That in ventilated one was also affected by dehumidification through ventilation layers. Under heating and humidification, the absolute humidity increased depending on temperature rise and water flux within walls. In conventional one, condensation was frequently observed on felt in walls and others because of accumulated humidity, while in ventilated one, humidity was kept lower within walls even under heating, because humidity in walls was discharged through ventilation layers. Condensation was also scarcely observed on waterproof moisture-permeable sheets in walls and others. 3 refs ., 39 figs 1., tab.

    Research and development has been made on a cover soil replacement process utilizing waste papers for final disposal facility and a soil flow-out prevention process. This paper summarizes the achievements in fiscal 2000. In evaluating waste paper fibers and waste paper binder films, the safety level was assumed sufficiently high if the fibers are used for the cover soil replacement process for final disposal facility. However, films may have a possibility of destruction if force is applied by such as heavy machines running on the films, hence it must be avoided. According to the on-site scattering test using unattended mixed slurry spraying machine capable of being remotely controlled, the coverage was found good, and scattering of incineration residues can be prevented completely. With regard to monitoring of hydrogen sulfide gas, a system having a hydrogen sulfide sensor and GPS mounted on a slurry spraying machine capable of remote control operation was completed, and its usefulness was verified. By using a wastes disposal facility simulating device, investigations were performed on effects on seepage water and wastes when the cover soil replacing material utilizing waste papers is used, and on changes in the properties of the cover soil replacing material.

    Pull-out tests were carried out to examine basic anchorage behaviors of through holes for beam re-bars by using a PG connection method, in which columns and beam-column joints with through holes for beam re-bars in the reinforced concrete framed construction are precast simultaneously. Specimens made by the PG connection method showed better anchorage behaviors than specimens made by the conventional anchorage method. In case of anchorage width of 80cm and concrete strength of about 350kgf/cm{sup 2}, it was recognized that large slipping of re-bars did not occur under allowable bond stress when the interval between re-bars was not less than 15cm and covering depth to the core of re-bars was not less than 8cm. Concerning a specimen which did not show splitting bond failure because of lateral compressive stress, bond stress of re-bars when large slipping occurred was 1.5 times or more in comparison with the allowable bond stress. Since this specimen held high slipping rigidity even after increase of slipping, its anchoring stress increased by 32-57% compared with a specimen without lateral compressive stress. 4 refs., 7 figs., 3 tabs.

    The details were outlined of the PR event 'Clean Energy Festa' which was carried out for PR activities for spread of new energy and clean energy vehicles. The festa was implemented in Yokote (Akita prefecture), Nagoya, Osaka, Yokohama and Hiroshima. The details of each place were reported in terms of the following: outline of the implementation, map of the place and booths, opening ceremony, management at entrance, dome theater, place for enjoying/relaxing, festival plaza, parking lot, PR related works, etc. In Festa in Yokote, more people gathered than expected. The reasons seem to be: the festa was held in the existing amusement facilities; the show using costumes of popular characters and gifts of the lottery were effective. As to new energy and clean energy vehicles, appeal was made mainly by stamp rally and questionnaire survey. By moving people inside the place, it helped people to have an understanding of clean energy vehicles. Almost the same effects were recognized also in the other places. (NEDO)

    Japan currently produces about six million tons of coal ash annually, whose effective bulk utilization to earth engineering materials is an important issue of technological development. A slurry may be made by mixing the following three kinds of materials: fly ash discharged from power plants exclusively burning dust coal (F), gypsum generated as a by-product in a stack gas desulfurizing process (G), and commercially available cement (C). The slurry would be called an FGC slurry taking the first letters of the materials. This paper presents the results of laboratory tests, in-situ execution tests and centrifuge model testing on engineering characteristics of soils improved by the FGC slurry when the slurry is applied to implementing the deep mixing method. As a result, a large number of findings were obtained including the following matters: the FGC deep mixing method makes it possible to improve ground beds having small deformation coefficient with the same accuracy as in the cement-based deep mixing (CDM) method at strengths lower than 5 kg/cm {sup 2} which is difficult with the CDM method, not to speak of strengths equivalent to that is possible with the normal CDM method; and development of a ground bed with improved strength is possible without being governed by quality and kinds of the fly ash. 1 ref., 23 figs., 5 tabs.

    A machine for vertically cutting steel pipe piles has newly been developed for the purpose of removing the end portions the shore protection steel pipe piles which interfere with the shield tunneling work in the Ohokagawa River tunneling section on the Minato Mirai 21 Line. This paper reports the development of the machine for vertically cutting steel pipe piles, and a method of cutting the shield tunneling work hindering piles under the ground by using this machine. The obstacle-constituting portions of the piles are removed by destroying the copings, excavating the interior of the piles to make the same hollow so that a cutting machine can be inserted, and cutting the piles vertically and horizontally. The basic structure of the cutting machine comprises a lower cutting unit for making forward and backward and upward and downward movements of a cutter, and an upper movable unit for controlling the rotation of the cutting unit. The cutting of a pile is done by projecting the cutter by a cylinder the base of which is joined to a cutter driver, and then moving the rotating cutter upward. The amounts of movements of these parts are detected by sensors, and an arbitrary range of the underground portion of a pile can be cut by a remote control operation. 10 figs., 1 tab.

    What impedes the popularization of the guided boring system is the functional insufficiency of the drilling position measuring method. For the purpose of properly dealing with the situation, efforts are made to develop a new drilling position measuring method which is highly reliable even when there exist previously buried pipes or electromagnetic noise. Activities are conducted in the two sections of (1) the study of an drilling position measuring method not to be easily affected by magnetic noise and (2) the study of a method for detecting previously buried objects. In section (1), based on the technology of a drilling position measuring system (locator) which is currently the most popular among horizontal drilling systems, a signal processing technology capable of reducing the effect of noise and a new position measuring method are contrived, and it is proved by the use of an experimenting system that they work effectively. In section (2), with attention paid to the small horizontal drilling device, an underground radar technology with the radar probing into the ground from the ground surface or from a drilling head is studied as an effective and easy-to-use method for detecting previously buried steel pipes.

    The problems encountered in construction of sewarage systems in urban areas are reduced pitting sites, and construction of deeper, longer-distance and more sharply curved systems, resulting from overpopulation both on and under the ground. The Arakawa trunk line, constructed by the Tokyo Metropolitan Government, is to connect the existing Mikawashima sewage plant to Higashioku Sewage Purification Center now under construction, 2400m in total length, 40m as pit depth and 15m in the minimum curvature R, and needs shielding works for segment external forms of 4700mm. The construction method employed is the pit/drift continuous shielding method, which allows continuous works from a pit to drift by a single shielding machine. The machine is equipped with a spherical body holding a drift shielding machine built in a pit shielding machine, to excavate a pit to a given depth, and then a drift after turning the spherical body by 90deg. Each pit is equipped with a lift and each drift with an adequate system to move the segments. Bag-equipped segments are used for sharp curves. The pit/drift shielding method has been already applied to 5 cases, including the Arakawa trunk line construction, centered by those for sewarage systems. 1 ref., 6 figs.

    MSD (mechanical shield docking) method is a method for mechanical docking two shields which have been extended simultaneously from both ends of one section of tunnel boring to shorten work term. One of the two shields has a piercing ring on its tip and another has a receiving ring. In the final stage of boring, the two ring are docked directly by piercing-receiving. The MSD method has been applied for the first time under sea to a boring work of an under sea tunnel on a route of a gas pipe line from Chita LNG base, Aichi prefecture to the title power station. This paper reports the outline of the shield machine and horizontal boring for confirming shield position that is a key to an underground docking as well as docking work. In the horizontal boring, after the shield machine on receiving side had reached the docking point predestined, the shield machine on piercing side conducted primary boring at 20 m front of the docking point and then secondary boring at 3 m front, whereby the boring hole was pierced into the shield machine on the receiving side. The accomplishment of this work made certain the reliability of MSD method even under sea. 1 ref., 13 figs., 3 tabs.

    The thermal and air distribution characteristics of the air circulation wall in a heat-insulated system were grasped using an experimental model. In this paper, the difference in the heat exchange between the wall and air was confirmed based on the radiation on the circulation layer`s surface. In this system, thin air circulation layers with ventilating holes at the top and bottom are attached to the south and north outer walls of a wooden building. This system is a kind of passive solar house that achieves the insolation screening effect and the temperature rising effect based on solar collection. The heat flow in a circulation layer is eliminated by the natural convection heat transfer on the outer wall. The heat flow passing through insulating materials is the heat transfer by radiation. The heat flow based on the in-layer natural convection is increasingly eliminated by the decrease in temperature on the air circulation layer`s surface. The decrease in room surface temperature using aluminum foil and the reflective heat-insulated effect showed that the heat passing through the wall surface decreases as the convection heat transfer in an air circulation layer increases. 6 refs., 20 figs., 3 tabs.

    This report summarizes the experimental result on the structural performance of precast prestressed concrete (PC) composite slab work, and a construction method with prestressed connection of PC. Although a double T type precast PC slab (DT board) is frequently used as buried form for slabs, it requires extremely complex bar arrangement and complicated works. The reinforcement method of supports using deformed hair pin type bars was thus devised which has a structural performance higher than that of the previous methods as well as simple bar arrangement and superior workability. For the reinforced DT board (DP slab) and the composite slab construction method using the DP slab, the structural safety and retained use environment were confirmed by structural performance test and construction test. The foundation and footing beam of the Bibai factory office building were constructed by the conventional method considering the construction method, while the column, beam and floor by this method using PCa members. The upper building frame was thus completed for as short as 23 days. 5 refs., 15 figs., 4 tabs.

    Seeds from six varieties of Gossypium hirusutum and from one variety of Gossypium barbadense were cultured in plastic containers (20 x 60 x 30 cm) with compost (Terfgroup, Netherlands). Germination readings were taken 14 days after culture, where plants with first true leaf was chosen for readings. The highest percentages of germinations were 83.3 (C6040) and 80 % (Rakka 5). Seeds of Rakka 5 were subjected to gamma radiation (60 C o) with radiation activity of 4 kci using the Gamma cell (Isolvated, made in Russia) at the Radiation Technology department at the AECS. The following doses were used in a rate of 1.8548 KGry/h: 100,150, 200, 250, 300, 350,400 and 500 Gry. On the other hand, seeds of C6040 were subjected to 100,150,200, 250 and 300 Gry. The results indicated the effects of gamma radiation doses on germination rate, plant height, distance between cotyledons leaves and first true leaf and flowering time.(author)

    For the purpose of promoting installations of PV system and making use of the unused space for which a rise in the PV demand equal to that in houses, building roofs, etc. is expected, examination/research for much newer forms of land installation are proceeded with, and evaluation/verification of reliability/durability are conducted of new installation processes using thin film solar cells, adhesives, etc. In this fiscal year, for the purpose of contributing to the study to be widely made on various installation processes, the actual survey was conducted of various applications of the system which are being planned and introduced in Japan and abroad. Emphasis was placed on making new forms of installation applicable to Japan clear. Concretely, in addition to the study of new examples, the following were conducted: renewal of existing details of the survey, and electronic filing of system block charts/pictures as a key to the information supply by electronic media such as CD-ROM. Also conducted was a study for translating the contents into English or writing them both in Japanese and English. Further, the database was made newer using these results of the most up-to-date survey, and at the same time, the results were indicated of the statistical analysis of the usage, system form, power generation scale and element equipment of various systems.

    Based on previous results of the same nature, one nitrogen rate 180 kg N ha -1 was tested under two-irrigation methods, surface irrigation and drip fertigation of cotton (Cultivar Rakka-5) for two consecutive seasons 2000 and 2001. The study aimed to answer various questions regarding the applicability of drip fertigation at farm level and the effect of its employment on yield and growth parameters, compared to surface irrigation. Nitrogen fertilizer was either injected in eight equally split applications for the drip fertigated cotton or divided in four unequally split applications as recommend by Ministry of Agriculture (20% before planting, 40% at thinning, 20% after 60 days from planting and 20% after 75 days after planting). 15 N labeled urea was used to evaluate nitrogen fertilizer efficiency. The experimental design was randomized block design with seven replicates. Results showed that drip fertigation led to water saving exceeding 50% in some cases. Field germination percentage was highly increased under drip- fertigated cotton relative to surface-irrigated cotton. Dry matter and seed cotton yield of surface-irrigated cotton was slightly higher than that of drip-fertigated cotton in the first growing season. The reason for that was due to the hot spill that occurred in the region, which exposed the cotton crop to water stress and consequently pushed the cotton into early flowering. Lint properties were not affected by the introduction of drip-fertigation. Actually some properties were improved relative to the standard properties identified by the cotton Bureau.Nitrogen uptake was slightly increased under drip fertigation whereas nitrogen use efficiencies were not constant along the growing seasons. The reason for that could be lateral leaching and root proliferation into the labeled and unlabeled subplots. Field water use efficiency was highly increased for both growing seasons under drip fertigation practice. The rate of field water use efficiencies

    Full Text Available Reverse transcriptase from avian myeloblastosis virus (AMV was the subject of the study, from which the investi- gations of the Department of biosynthesis of nucleic acids were started. Production of AMV in grams quantities and isolation of AMV reverse transcriptase were established in the laboratory during the seventies of the past cen- tury and this initiated research on the cDNA synthesis, cloning and investigation of the structure and functions of the eukaryotic genes. Structures of salmon insulin and insulin-like growth factor (IGF family genes and their transcripts were determined during long-term investigations. Results of two modern techniques, microarray-ba- sed hybridization and SAGE, were used for the identification of the genes differentially expressed in astrocytic gliomas and human normal brain. Comparison of SAGE results on the genes overexpressed in glioblastoma with the results of microarray analysis revealed a limited number of common genes. 105 differentially expressed genes, common to both methods, can be included in the list of candidates for the molecular typing of glioblastoma. The first experiments on the classification of glioblastomas based on the data of the 20 genes expression were conducted by using of artificial neural network analysis. The results of these experiments showed that the expression profiles of these genes in 224 glioblastoma samples and 74 normal brain samples could be according to the Koho- nen’s maps. The CHI3L1 and CHI3L2 genes of chitinase-like cartilage protein were revealed among the most overexpressed genes in glioblastoma, which could have prognostic and diagnostic potential. Results of in vitro experiments demonstrated that both proteins, CHI3L1 and CHI3L2, may initiate the phosphorylation of ERK1/ ERK2 and AKT kinases leading to the activation of MAPK/ERK1/2 and PI3K/AKT signaling cascades in human embryonic kidney 293 cells, human glioblastoma U87MG, and U373 cells.
