    Caracteristicile unor instalaţii pentru studierea efectelor galvanomagnetice [Articol]
    (USARB, 2006) Nicorici, Andrei; Rusu, Alexandru; Todosiciuc, Alexandru; Cheptea, Virgil
    Se caracterizează parametrii instalaţiilor pentru măsurarea tensiunii termoelectromotoare, a rezistenţei electrice şi a tensiunii Hall. Pentru calibrarea lor au fost studiate trei probe de n-InSb. Au fost stabilite dependenţele s =¦(T), n=¦(T), RH=¦(T), m H =¦(T).

    Reabilitarea solurilor puternic erodate prin fertilizare şi cultivarea ierburilor perene [Articol]
    (USARB, 2017) Rusu, Alexandru
    Rehabilitation of heavily eroded soils by fertilization and cultivation of perennial herbs. It has been experimentally established that in an efficient anti-erosion framework of agricultural land by using fertilizers and cultivating perennial grasses within 6-8 years, it is possible to restore the humus content of arable highly eroded chernozems. For six years, the humus content has increased from herbs by 13%, and from herbs and fertilizers by 19-26%. The share of fertilizers in the total growth of humus ranged from 35 to 54%. Compared with manure, the annual application of N60P60 has significantly increased humus. With an increase in the dose of manure from 50 to 200 tons / ha, the increase in humus decreased from 50 to 35%.
