Mesospheric temperatures derived from spectroscopic measurements of the hydroxyl (OH) nightglow have been observed from Rothera (67.6°S, 68.1°W) and Halley (75.6°S, 26.6°W) stations in Antarctica during the 2002 austral winter season. In addition to the normal seasonal changes, the temperatures at both sites, separated by 1658 km, showed several simultaneous shifts in temperature of between 10 and 20 K. These changes abruptly occurred in the space of 2–3 days and lasted for several days. These rapid variations in temperature were associated with large swings observed in the meridional component of the mesospheric wind measured by the Rothera MF radar. As there appeared to be no phase shift between the temperature variations at the two longitudinally separated stations indicating that planetary-waves caused the changes, these large-scale changes have been interpreted as variations in the inter-hemispheric meridional jet, and a corresponding modulation of the mesospheric descent and adiabatic heating rates over the polar region.
Lovastatin is an important fungal secondary metabolite inhibiting the enzyme which catalyzes a rate-limiting step in the biosynthesis of cholesterol. As microfungi of the genus Penicillium are active producers of cholesterol lowering agents (statins), studies of this genus have gained considerable momentum. In Malaysia, both agricultural soils and those of natural ecosystems are valuable sources of filamentous fungi, whose biotechnological potential in terms of lovastatin production has not been well investigated. The aim of the present study is to determine lovastatin-producing potential of Penicillium spp. microfungi isolated from soil in Pahang State (Malaysia). Fungal cultures were isolated, purified, and classified based on characters of colony morphology and microscopic features. All identified representatives of Penicillium were tested for their ability to produce lovastatin. Isolates were cultivated in submerged fermentation. High-performance liquid chromatography (HPLC) was used for detection of lovastatin. Among 54 fungal cultures examined, four Penicillium strains were confirmed to produce this statin. The isolate Penicillium sp. ESF2M was the strongest lovastatin producer, with a yield of 20 mg/l. This strain should now be subjected to a further strain improvement program to maximize the yield of this important statin.
Every national spacecraft charging related design guideline or design standard includes prohibitions against floating, or ungrounded, connector pins. The rationale is obvious. A floating connector pin represents ungrounded metal with a propensity to accumulate charge from the space plasma environment and, upon breakdown, effectively couple the discharge energy directly into sensitive system electronics by virtue of adjacent pins and cables. Satellite designers may recognize that, seemingly as common as the rationale is obvious, there are instances in violation of this clear guideline and impassioned arguments for permissions to do so. This paper represents a comprehensive effort to quantitatively, theoretically, analytically, and empirically assess the risk associated with ungrounded connector pins in the selected (geostationary earth orbit and medium earth orbit) orbits.

NIOC awards new contract to MAPNA for the Parsi and Paranj oil fields. (Credit: NIOC/Hamidreza Norouzi) The MAPNA Group has secured a 10-year contract from the National Iranian Oil Company (NIOC) to further develop the Parsi and Paranj oil fields in Iran.Under the terms of the Iranian petroleum contract (IPC), the company will be responsible for boosting the oil recovery rate and increasing production and exploitation of the two fields.The contract awarded to the MAPNA Group is based on an agreed plan for the comprehensive development and operation of the fields located in the southwest Khuzestan province, said NIOC.In August 2018, the MAPNA Group was given a contract from NIOC’s subsidiary National Iranian South Oil Company (NISOC) to develop the Parsi and Paranj oil fields, reported Financial Tribune.Through the latest contract, the Iranian oil company aims to see a maximum production of 85,000 barrels of oil per day.NIOC estimates a direct capital cost of $876.6m for the project and an indirect cost of $235.3m. On the other hand, the cost of exploitation is projected to be $269m.Work expected to be done by MAPNA Group under the new contractAccording to the state-owned company, the scope of the contract covers upgrading and construction of surface installations, drilling of new wells, repairing existing wells, gas lift operation, split layer operation, drilling and EOR studies, piloting EOR plans, technology transfer, and research and development among others.The surface installations will include operation unit, desalination, gas injection facilities, flow, gas pressure collecting and boosting facilities, and transmission pipelines and other associated facilities.NIOC, in a statement, said: “Implementing this plan while increasing the crude oil production capacity of the country, will create widespread employment opportunities in Khuzestan province and also a favorable job market.”The Parsi oil field is located in the southern part of Dezful, nearly 125km from Ahvaz in southwest Iran. The Paranj oil field is located between the Karanj and Parsi fields, 75km from Behbahan and 40km from Ramhormoz.
