The spatial distribution of individuals of any species is a basic concern of ecology. The spatial distribution of parasites matters to control and conservation of parasites that affect human and nonhuman populations. This paper develops a quantitative theory to predict the spatial distribution of parasites based on the distribution of parasites in hosts and the spatial distribution of hosts. Fo...

The rapidly growing world energy use has already raised concerns over energy resources and greenhouse gas (GHG) emissions. Since the global contribution from residential buildings towards energy consumption, has steadily increased between 20% and 40% and as large openings have considerable energy and heat loss in dwellings, this paper establishes a coefficient of heat loss and air infiltration ...

BACKGROUND Data are lacking on the efficacy and safety of a combination chemotherapy regimen consisting of oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX) as compared with gemcitabine as first-line therapy in patients with metastatic pancreatic cancer. METHODS We randomly assigned 342 patients with an Eastern Cooperative Oncology Group performance status score of 0 or 1 (on...

To study interferential effect of lamb's-quarters (Chenopodium album L.) on marigold (Calendula officinalis) yield and lamb's-quarters seed production two factorial field experiments were conducted in Tabriz, Iran, during 2010-2011. Treatments were densities of lamb's-quarters (0, 2, 4, 6 and 8 plants per meter row) and relative times of its emergence (0, 10, 20, 30 and 40 days after marigold e...

BACKGROUND The efficacy of surgery for patients with non-small-cell lung cancer is limited, although recent studies suggest that preoperative chemotherapy may improve survival. We conducted a randomized trial to examine the possible benefit of preoperative chemotherapy and surgery for the treatment of patients with non-small-cell lung cancer. METHODS We studied 60 patients (59 men and 1 woman...

Soybeans grown with 2 millimolar NO(3) (-), which optimized apparent N(2) fixation by Rhizobium symbionts, showed significantly different rates of apparent photosynthesis and C(2)H(2) reduction during seedling development at two irradiances. Those physiological processes were lower for several weeks in plants grown at 1,500 microeinsteins per meter(2) per second than in those exposed to 700 mic...

In order to study the effects of rate and time of nitrogen application on vegetative characters, i.e., yield and yield components of rice (Zayandeh-rood variety), an experiment was conducted at Isfahan University of Technology research farm during summer 1996. Four N rates including (60, 90, 120 and 150 KgN/ha) and four splitting form (1- all N applied before transplanting 2- 1/3 N applied befo...
