Some machining properties of 4 wood species grown in Turkey

Kurtoğlu, Ahmet (Dogus Author)Determining wood machining properties and defining convenient usage areas for native wood species is important for evaluating surface quality. Wood machining is a performance criterion indicated after planing, shaping, turning, mortising, boring, and sanding. This study selected 2 softwood species (European black pine and cedar of Lebanon) as well as 2 hardwood species (sessile oak and black poplar), which are commonly used and grown in Turkey. Preparation of samples and machining were carried out according to the 2004 ASTM D 1666 standards for determining machining properties. Sessile oak (Quercus petraea) had an excellent performance in all machining processes. Black poplar (Populus nigra L.) yielded the lowest results for the sanding test. A perfect surface quality was obtained with a feed rate of 8.6 m/min for hardwoods at a 25° cutting angle in planing, and at a 15° angle for softwoods

Comparación de las características físicas y motrices de personas con discapacidad visual totalmente baja visión

The purpose of this study is to compare the physical and motor characteristics of individuals with total visual impairment (TVI) and individuals with low vision (LVI). 250 participants (136 participants=TVI, 114 participants=LVI) bettween the age 10-19 participated in the study. Participants’ anthropometric features (age, height, weight, and BMI), balance, sitting reach, standing long jump, shuttle run, vertical jump, shuttle, hanging with bent arm, and handgrip strength were measured. Dr. Lovett's manual muscle strength measurement (MMSM) was used to determine the strength parameters. The strength of arm flexion strenght (FS), arm extension strenght (ES), leg FS, leg ES, hip FS, hip ES,  back and abdominal strenght were measured. For statistical analysis the SPSS 25 was used. Therefore, Independent Sample T Test was used to determine the difference between the two groups. As a result of the statistical analyzes, a significant difference was found between TVI and LVI in balance, sit and reach, standing long jump, shuttle run, vertical jump, shuttle, handgrip strength, abdominal strength, back strength, hip FS, arm FS, and arm ES (p<0.05). LVI's motoric properties were better than TVI. There was no difference between groups in bent arm hanging (BAH), hip ES, leg FS and leg ES (p>0.05). As a result of the study, it was found that the degree of vision significantly affects physical and motor development. TVI develop slower than LVI in terms of physical and motor characteristics. This study was conducted to reveal the difference in motor characteristics between TVI and LVI. According to the results of this study; In order to prevent insufficient physical and motor development in TVI individuals in developmental age, it is recommended to be supported with sportive activities.

The differences in the surface structure and three dimensional models were examined visually

Modelling Marshall Design Test Results of Polypropylene Modified Asphalt by Genetic Programming Techniques

Determining Marshall design test results is time consuming. If the researchers can obtain stability and flow values by mechanical testing, rest of the calculations will just be mathematical manipulations. Marshall stability and flow tests were carried out on specimens fabricated with dierent type of polypropylene fibers. It has been shown that addition of polypropylene fibers improved Marshall stabilities and Marshall quotient values in a considerable manner. Input variables in the developed genetic programming model use the physical properties of standard Marshall specimens such as polypropylene type, polypropylene percentage, bitumen percentage, specimen height, calculated unit weight, voids in mineral aggregate, voids filled with asphalt and air voids. Performance of the genetic programming model is quite satisfactory. Besides, to obtain main eects plot, a wide range of parametric studies have been performed.The presented closed form solution will also help further researchers willing to perform similar studies, without carrying out destructive tests

Utjecaj uvjeta obrade na hrapavost površine pri blanjanju i brušenju masivnog drva

It is important to evaluate the effect of machining and wood machining properties on surface quality to determine and upgrade the data on wood machining properties and to defi ne convenient usage areas for some native wood species of Turkey. European black pine (Pinus nigra Arnold) and cedar of Lebanon (Cedrus libani A. Rich) are two softwood species and sessile oak (Quercus petraea Lieble) and black poplar (Populus nigra L.) are two hardwood species commonly used and grown in Turkey. These trees species were selected as experimental material for the study. Roughness measurements are significant in the determination of wood surface quality for use as a final product. This study evaluated roughness measurements after planing and sanding operations, and found that the highest value for average roughness (Ra) was observed as 6.780 μm. in sessile oak, followed by black poplar at 6.338 μm, cedar of Lebanon at 4.836 μm, and black pine at 4.740 μm. The average roughness values for wood in directions perpendicular to the grain and along the grain from highest to lowest were sessile oak, black poplar, black pine, and cedar of Lebanon.Istraživanje utjecaja mehaničke obrade i svojstava drva na kvalitetu obrađene površine važno je kako bi se dopunili podaci o svojstvima drva pri mehaničkoj obradi i defi nirala prikladna područja upotrebe nekih domaćih vrsta drva u Turskoj.
