Инсоният тарихида савдо йўлларининг аҳамияти жуда муҳим ўрин эгаллайди. Кишилик жамиятининг бронза давридан, баъзи жойларда ундан ҳам анча аввал, маълум ихтисослашган йўллар пайдо бўлганлигини биламиз. Уларнинг пайдо бўлишида қабилалар, халқлар ва давлатлараро алоқалардан келиб чиққан иқтисодий, этник, сиёсий ва маданий эҳтиёжлар сабаб бўлди. Дастлаб Ўрта ва Яқин Шарқда Бадахшоннинг лаъл(лазурит)ига бўлган эҳтиёж “лазурит йўли”нинг вужудга келишига олиб келган. Милоддан аввалги VI-IV асрларда эски йўллар асосида Эронда (Ахамонийлар империяси даврида такомиллашиб борган) “шоҳ йўли” таркиб топади. Кейинчалик бу йўллар негизида Буюк ипак йўли ва бошқалар такомиллашиб боради.
Today, with the development of the construction industry, the demand for cement is also increasing. In increasing the volume of construction, cement is one of the resources available at the price of finished objects is achieved through cost reduction due to the use in the construction of modern high-quality building materials and products with lower energy consumption and with improved characteristics. Of particular importance is the production of effective cements based on industrial waste. On a global scale, special attention is paid to the development of new compositions of cements that increase the fire resistance of building structures and the most important task of research in this direction is the development of compositions based on industrial waste for Portland cement. When developing composite additives and based on them new compositions of highly effective composite Portland cement, in this direction it is necessary to substantiate a number of the following scientific solutions, in particular: development of new methods for the production of effective types of building products based on composite additives; development of new compositions for the production of nanocements with the participation of secondary raw materials; increase of concrete strength indicators on sulfate-resistant cements; optimization of the composition of raw materials in obtaining energy saving clinkers and cements; modernization of production technologies for white and decorative Portland cement; to increase the production of auxiliary cements, the use of alternative sources of active mineral additives and filler additives.

В хирургической стоматологии дентальная имплантация с наращиванием костной ткани у больных сахарным диабетом занимает особое место. Это одна из немногих отраслей, наряду с тканьевой инженерией, где мы можем говорить о репаративной регенерации - самовосстановлении организма в условиях, созданных врачом хирургом-имплантологом
