This study was carried out to determine the effect of growing conditions underdifferent altitudes on seed production in different potato crosses in Tokat Provinceof Turkey in 2015. Plants were grown and crosses were made in open field or nethouse in Tokat location (altitude 600 m asl.), open field or net house in Artovalocation (altitude 1200 m asl.), or controlled polycarbonate greenhouse. Fifteendifferent crosses were made between 12 parent cultivars. Production of hybridpotato seed was considered “crossing success”. Results showed that parentcultivars and cross combinations affected crossing success and no seeds wereproduced from some combinations while some combinations produced abundantseeds. The highest number of seeds were produced in controlled polycarbonategreenhouse, whereas very low amount of seeds were produced under low altitude(600 m asl.) open field conditions. Polycarbonate greenhouse produced 47.3% ofall seeds, while low altitude net house produced 19.8%, high altitude open fieldproduced 15.8%, high altitude net house produced 13.6% and low altitude openfield produced 3.5%. It was concluded that for a high crossing success, potatocrossing should be made by controlled polycarbonate greenhouse conditions and 23C0 day / 17 C0 night temperatures produced more hybrid seeds.

The acute effects of active and passive ascent to high altitude on plasma volume (PV) and rates of synthesis of albumin and fibrinogen have been examined. Measurements were made in two groups of healthy volunteers, initially at low altitude (550 m) and again on the day after ascent to high altitude (4,559 m). One group ascended by helicopter (air group, n = 8), whereas the other group climbed (foot group, n = 9), so that the separate contribution of physical exertion to the response could be delineated. PV was measured by dilution of125I-labeled albumin, whereas synthesis rates of albumin and fibrinogen were determined from the incorporation of isotope into protein after injection of [ ring-2H5]phenylalanine. In the air group, there was no change in PV at high altitude, whereas, in the foot group, there was a 10% increase in PV ( P < 0.01). Albumin synthesis (mg · kg−1· day−1) increased by 13% in the air group ( P = 0.058) and by 32% in the foot group ( P < 0.001). Fibrinogen synthesis (mg · kg−1· day−1) increased by 40% in the air group ( P = 0.068) and by 100% in the foot group ( P < 0.001). Hypoxia and alkalosis at high altitude did not differ between the groups. Plasma interleukin-6 was increased modestly in both groups but C-reactive protein was not changed in either group. It is concluded that increases in PV and plasma protein synthesis at high altitude result mainly from the physical exercise associated with climbing. However, a small stimulation of albumin and fibrinogen synthesis may be attributable to hypobaric hypoxia alone.

<p>Yellow Nematoda sista (Globodera rostochiensis) is one of interfering plant organism in potatoes plants that bothers farmers in Indonesia. Many controls done by farmers during this time uses chemist pesticide. The using of chemist pesticide  continuously  can  threaten  human  environment  and  healthy.  The existence of endofit bacteria might became one of nematode controlling agent which is hospitable, because endofit bacteria can produce toxic compound in nematode. The aim of this research is to find out the filtrate potential of endofit bacteria to the growth of yellow nematode sista population (Globodera rostochiensis) in potatoes plants.  This research is done in Microbiological and Greenhouse Laboratory, Biology Department, Science and Technology Faculty, UIN Maulana Malik Ibrahim Malang and Pest and Plant Disease Laboratory, Agriculture Faculty, Universitas Brawijaya Malang.  This research is done in December  2011  until  April  2011  by  using  Rancangan  Acak  Lengkap  (RAL) method. Bacterial filtrate is made in a way of making endofit bacteria grow in TSB  media  for  48  hours,  then  disentrifugasi  with  speed  13.000  rpm  for  15 minutes. Next, it is tested in yellow nematode sista in potatoes plants in the greenhouse. The result of this research shows that endofit bacteria filtrate can obstruct the growth of sista Globodera rostochiensis population. Three from those six isolates which have high ability in pressing sista Globodera rostochiensis population in 100 gram of soil are isolate AA (91%), DH (81%) and BE (81%). Isolate AA can press sista Globodera rostochiensis population in the high scale, which reach until 91%. All endofit bacteria isolate (Isolat AA, AH, BA, BE, DA and DH) can increase the growth of potatoes plants, they are the height of plant and the weight of potatoes plants root.</p>

SummaryThis paper presents the twenty or more principal problems encountered in the designing of aeroplanes for passenger service at altitudes of about 20,000 to 30,000 feet, together with a discussion of the recent attempts made in the United States to solve these problems. Particular attention is given to the design features of pressure cabins for maintaining low altitude air pressure at high altitudes.
