Published: February 2022

Tımar sistemi, Osmanlı Devleti’nde toprak rejiminin esasını teşkil etmekle birlikte devletin siyasî, askerî ekonomik ve içtimaî yapısı üzerinde oldukça önemli bir role sahip olmuştur. Fethedilen yerler üzerindeki hâkimiyet, uygulama sahası oldukça geniş olan bu sistem sayesinde tesis edilmiştir. Bu sistemin en önemli hususlardan biri de şüphesiz tımar sisteminin bel kemiğini oluşturan tımar sahiplerinin tımarlarını mahlûl (boş) kılan sebepler ve tımar almaya layık olan yeni sipahilere boş olan tımarların intikali meselesidir. Fevt, feragat ve sefere gitmeme gibi nedenler bir tımarın intikaline sebep teşkil eden başlıca hususlardır. Osmanlı yönetimi sipahinin vefatı halinde tımarını oğullarına veya kardeşine ya da kan bağı olmayan başka bir sipahiye bazı şartlar dâhilinde tevcih etmektedir. Sipahinin kendi isteğiyle veya başka bir nedenden dolayı tımarından feragat etmesi, hizmetini ihmal ederek sefere katılmaması ya da firar etmesi durumunda boşalan tımarlar çoğunlukla çeşitli seferlerde ve muharebelerde gösterdikleri hizmet ve yararlılıkları mukabelesinde yeni sipahilere intikal etmektedir. Osmanlı Devleti’nde tımar sisteminin işleyişini ve tarihsel gelişimini tahrir kayıtlarını içeren Mufassal ve İcmâl Defterleri ile tevcih tezkire kayıtlarının kronolojik olarak tutulduğu tımar Ruznamçe Defterleri sayesinde takip edebilmekteyiz. Bu makalede Sivas sancağında bir tımarın intikaline yol açan sebepler 36, 239, 392 ve 645 numaralı Tımar ve Zeamet Ruznamçe Defterleri ve 1066 numaralı Yoklama Defteri esas alınarak incelenmiş, defterlerin sağladığı verilere dayanarak bazı tespit ve değerlendirmelerde bulunulmuştur.

The structure of model alloys of the aluminum-zirconium system and industrial 1973-type alloy with an increased content of zirconium after rapid cooling to temperatures of the liquid-solid region and isothermal holding at these temperatures has been studied. It is shown that during primary crystallization of intermetallic precipitates with low crystallization rate, it is advisable to use the model of decomposition of supersaturated solid solutions. It was determined that formation of Al3Zr particles leads to zirconium decrease in the solid solution in center and grain boundary. Under certain crystallization conditions, there is an incubation period for the zirconium intermetallic compounds precipitation. It is shown that the incubation period for aluminum with 0.25 % zirconium is more than 2 minutes, and for 0.5 % zirconium — less than 0.5 minutes. The value of the dendritic parameter of the 1973-type alloy with an increased zirconium content during two-stage crystallization corresponds to the known regularity of the change in the dendritic parameter depending on the cooling rate. Casting of alloy ingots of 1960-type alloy with 0.27 % Zr by the two-stage cooling with the use of a water-cooling tray has been tested. This made possible to produce ingots with 84 mm diameter without the formation of primary intermetallic compounds. The mechanical properties of forgings from such ingots showed an increase in ductility by 20 % while maintaining the strength characteristics.

The paper describes the extraction of the rare earth element Sm3+ from aqueous buffer systems by a graphene-based nanostructured composite, modified using an organic polymer – polyhydroquinone. The authors determined the important parameters of the sorption-desorption of Sm3+ ions on a new nanocomposite “graphene oxide/polyhydroquinone” during a batch test, such as: initial concentration, the sorbent weight, pH of the solution, sorption rate constants, maximum sorption capacity of the nanocomposite, percentage sorption and desorption, entropy and enthalpy of the Sm3+ extraction process. The kinetic, isothermal and thermodynamic dependences allowed to propose of the Sm3+ ions adsorption mechanisms. The kinetic data were processed by pseudo-first- and second-order, Elovich and intraparticle diffusion models, and adsorption isotherms — using the Langmuir, Freundlich, Temkin, Dubinin-Radushkevich equations. As a result of kinetic studies, the contact time of the samarium adsorption was determined — 15 min, while the sorption capacity was 100 mg·g–1. It was found that the absorption of Sm3+ ions proceeds by a mixed diffusion mechanism and limited by the interaction “samarium ions : sorbent functional groups”. According to the Langmuir model, the maximum sorbent sorption capacity was 333.3 mg·g–1. Thus, the high efficiency of the developed graphene oxide/polyhydroquinone nanocomposite for purification of aqueous media from rare earth elements was confirmed.

Ferrogels based on polyacrylamide with embedded magnetic particles of strontium hexaferrite SrFe12O19 with their content up to 17.9 wt. % have been synthesized and studied. The enthalpy of adhesion of polyacrylamide to the surface of particles was determined by the calorimetric method using a thermochemical cycle. Its negative values indicate good adhesion. This leads to a significant decrease in the degree of swelling of ferrogels with increasing particle content. The modulus of elasticity of ferrogels was measured under uniaxial compression with and without an external uniform magnetic field of 27.5 mT. The effect of a uniform magnetic field of 420 mT on the magnetostriction of ferrogels has been studied. It has been shown that ferrogels based on polyacrylamide filled with strontium hexaferrite underwent universal stretching in a magnetic field, leading to an increase in their volume and additional swelling.
