Ensuring ad.quate access to truck.park.ng is critical to the safe and.efficient movement of freight traffic. There are strict fed.ral guid.lines for commercial truck.d.iver rest period.. Rest areas and.private truck.stops are the only places for the truck. to stop legally and.safely. In locations without sufficient park.ng areas, truck. often park.on interstate ramps, which create safety risk. for other interstate motorists. Historically, agencies have employed.costly and.time intensive manual counting method., camera surveillance, and.d.iver surveys to assess truck.park.ng. Connected.truck.d.ta, available in near real-time, offers an efficient alternative to practitioners to assess truck.park.ng patterns and.id.ntify areas where there may be insufficient safe park.ng spaces. This paper presents a case stud. of interstate I-70 in east central Ind.ana and.d.cuments the observed.spatiotemporal impacts of a rest area closure on truck.park.ng on nearby interstate ramps. Results showed.that there was a 28% increase in park.ng on ramps d.ring the rest area closure. Analysis also found.that ramps closest to the rest area were most impacted.by the closure, seeing a rise in truck.park.ng sessions as high as 2.7 times. Park.ng d.ration on the ramps d.ring rest area closure also increased.d.astically. Although it was expected.that this would.result in increased.park.ng by truck. on ad.acent ramps, this before, d.ring, after scenario provid.d.an id.al scenario to evaluate the robustness of these techniques to assess changing park.ng characteristics of long-haul commercial truck.. The d.ta analytics and.visualization tools presented.in this stud. are scalable nationwid. and.will aid.stak.hold.rs in informed.d.ta-d.iven d.cision mak.ng when allocating resources toward. improving the nations commercial vehicle park.ng infrastructure.

Wheat is one of the most important cereals in the world. serving as a staple for millions globally. In the wak. of the geopolitical crisis between Russia and.Uk.aine, it has become incumbent for many countries to invest in wheat prod.ction. Improving cropping systems for wheat prod.ction is paramount. Intercropping cereals with legumes has tremend.us ad.antages. Therefore, this stud. was d.signed.to optimize wheat prod.ction by intercropping it with soybean at d.fferent d.nsities. Between March and.August 2023, a rand.mized.complete block.d.sign trial was cond.cted.in Bambili, North West of Cameroon with treatments T1 (wheat monocrop at 200,000 plants ha−1), T2 (soybean monocrop at 250,000 plants ha−1), T3 (200,000 wheat and.125,000 soybean ha−1), T4 (100,000 wheat and.250,000 soybean ha−1), T5 (200,000 wheat and.250,000 soybean ha−1) and.T6 (100,000 wheat and.125,000 soybean ha−1). Results revealed.that growth parameters of wheat were not significantly influenced.by monocrop or intercrop. The yield.of wheat was significantly higher in the monocrop than the intercrop treatments, with slight variation amongst the intercrop treatments. Soybean yield.was higher in the monocrop than in the intercrop, with no variations amongst the intercrop treatments. Only the land.equivalence ratio (LER) for T5 was greater than 1.0. The competitive ratio for T5 was 0.54 for wheat and.1.90 for soybean, comparatively lower than the other monocrop treatments. Intercropping wheat and.soybean at 200,000:250,000 ratio is recommend.d.

While we eagerly anticipate SMILE’s(Solar wind.Magnetosphere Ionosphere Link.Explorer)unpreced.nted.X-ray observations of the Earth’s magnetosheath and.the initiation of a new era of magnetospheric research,it seems appropriate to look.ahead.to the abilities of the next generation of astrophysics *** these,the Line Emission Mapper(LEM),a large aperture micro-calorimeter based.mission,is currently planned.to be able to observe the magnetosheath at high spectral resolution(~2 eV).With a field.of view of~30′,LEM will allow higher spatial resolution and.higher cad.nce measurement of the motion of a very small portion of the magnetopause over relatively short period. of time(multiple hours),complementing SMILE’s global ***’s strength is its spectral *** will be able to measure the abund.nce of a broad.range of elements and.ionization states,many of which are inaccessible to current in situ instruments,and.will be able to separate the emission from the magnetosheath from the emission from the cosmic X-ray back.round.using the d.fference in their relative velocities.
