Rail car availability and the challenges associated with the seasonal dynamics of log movements have received growing attentions in the Lake Superior region of the US, as a portion of rail car fleet is close to reaching the end of its service life. This paper proposes a data-driven study on the rail car peaking issue to explore the fleet of rail cars dedicated to being used for log movements in the region, and to evaluate how the number of cars affects both the storage need at the sidings and the time the cars are idled. This study is based on the actual log scale data collected from a group of forest companies in cooperation with the Lake State Shippers Association (LSSA). The results of our analysis revealed that moving the current log volumes in the region would require approximately 400–600 dedicated and shared log cars in ideal conditions, depending on the specific month. While the higher fleet size could move the logs as they arrive to the siding, the lower end would nearly eliminate the idling of rail cars and enable stable volumes throughout the year. However, this would require short-term storage and additional handling of logs at the siding, both elements that increase the costs for shippers. Another interesting observation was the fact that the reduction of a single day in the loading/unloading process (2.5 to 1.5 days) would eliminate almost 100 cars (20%) of the fleet without reduction in throughput.

In a lengthy footnote to his article ‘Pronominalization, negation, and the analysis of adverbs’ (1970) George Lakoff makes the following interesting observation:All known selectional restrictions on the occurrence of lexical items are finite in scope. Usually they apply in the same sentence (subject–verb and verb–object selections) and sometimes one sentence away (verb–verb selections; i.e.force requires an activity verb in its complement) (160).

In the course of an investigation on refractory materials, in which the identification of minerals by their X-ray diffraction patterns had a prominent place, an interesting observation was made on a zircon of gem quality which was lent to us by the courtesy of Mr. B. W. Anderson.It may be recalled that the existence of three allotropes has been postulated in order to explain the considerable variations of physical properties which are found when comparing different specimens of zircon. In particular, densities ranging from 3·95 to 4·86 have been observed, the density of zirconium silicate, calculated from X-ray measurements, being 4·71.

AbstractAn interesting observation was made when studying the SNAr reaction between several 4-aryloxy-7-nitrobenzofurazans (2) and several amino acids leading to the apparition of detectable fluorescence from the substitution products3. Acidic amino acids reacted very slowly=while basic amino acids react fastest with2 having an unsubstituted phenyl or a 4-formyl-phenyl Ar group. Amongst neutral amino acids, proline reacts fastest at room temperature after 100 min. With2 having a methoxy-subtituted Ar group.

Writing in Griffith Review 13 about ‘being political now’, Mark Bahnisch described the Museum of Brisbane's Taking to the Streets exhibition as a ‘monument to the symbolism of the '60s’. On display, he wrote, were causes and experiences that ‘symbolise a generation’. It's an interesting observation, especially in an essay concerned with debunking generational stereotypes. For it seems Bahnisch himself may have fallen for, well, a generational stereotype. Aside from apparently missing the 75 per cent of the exhibition that didn't deal with the 1960s, he also seems to have failed to notice that the people represented in the interviews, the written accounts, the grainy images, the shaky film footage and the lists of arrests were not all of one generation. Ranging from punks to pensioners, students to seafarers, communists to Christians, they were in fact an amazingly motley bunch of citizens who shared a history only because they shared a desire for a better society and a belief that protest was a legitimate and worthwhile political activity. And, despite the mythology, the issues they mobilised around — war, racism, the nuclear industry, sexism, workers' rights, civil liberties — had been around as causes well before 1965. Even that icon of late 1960s radicalism — the peace symbol — came from earlier times, as Ted D'Urso so carefully explained in his exhibition interview.

Mathematicians and mathematical philosophers have often called attention to the fact that mathematical discoveries sometimes seem to anticipate important discoveries in physics. This is usually interpreted as meaning that the universe is “rational at the core” or that it was “created by a mathematician.” Such speculations are extremely enticing; but I wish to make an entirely different application of this interesting observation at the present time.

I was having some difficulty with a transparency (Fig. 1) that I had made for my trigonometry class. The transparency had a tendency to curl and roll into a cylindrical shape. I then noticed that if the cylinder were twisted to a particular size, the sine curve wrapped around the cylinder in a shape that resembled an ellipse (Fig. 2). To obtain this particular size, the cylinder was twisted so that the points labeled K matched, and the points labeled O matched. The sine curve wrapped around the cylinder about three times on the particular model I had.

The crystal structures of malachite Cu2(OH)2CO3 and rosasite (Cu,Zn)2(OH)2CO3, though not isotypic, are closely related. A previously proposed approach explaining this relation via a common hypothetical parent structure is elaborated upon on the basis of group–subgroup considerations, leading to the conclusion that the aristotype of malachite and rosasite should crystallize in the space group Pbam (No. 55). An ICSD database search for actual representatives of this aristotype leads to the interesting observation that the structure type of ludwigite (Mg,Fe)2FeO2BO3, which is adopted by several natural and synthetic oxide orthoborates M 3O2BO3, is closely related to the proposed malachite–rosasite aristotype and thus to the malachite–rosasite family of hydroxide carbonates M 2(OH)2CO3 in general. Relations within both structure families and their analogies are summarized in a joint simplified Bärnighausen tree.

Let μ be a probability measure on the real line ℝ, x a real number and δ(x) the probability atom concentrated at x. Stam made the interesting observation that eitheror else(ii) δ(x)* μn, are mutually singular for all positive integers n.
