Selecting the most suitable procurement strategy is crucial to the efficient management of supply chain operations and the prevention of stock shortages. Nevertheless, when dealing with a wide variety of products, this task becomes an intricate challenge. While traditional and advanced procurement tools are available, applying them across such diverse product ranges is often impractical. This rese

Extraterrestrial cratering was a critical component in the evolution of the early Earth, but discovery of very ancient and deeply exhumed impact structures remains elusive, as identification tools are in short supply. The recognition of such structures is hindered by post-cratering geological processes, whereby impact-induced features common in younger, upper-crustal craters may be lost. In this s

Perovskite nanocrystal superlattices are being actively studied after reports have emerged on collective excitonic properties at cryogenic temperatures, where energetic disorder is minimized due to the frozen lattice vibrations. However, an important issue related to structural disorder of superlattices at low temperatures has received little attention to date. In this work, it is shown that CsPbB

1,2-butadiene (1,2-C4H6) is one of four C4H6 isomers that could appear during pyrolysis and oxidation of heavier hydrocarbons and/or contribute to the formation of aromatic species in flames. However, it is seldom included in detailed kinetic mechanisms due to a lack of studies of its combustion characteristics. In this work, laminar burning velocities (LBV) of 1,2-butadiene flames have been measu

Experimental X-ray diffraction data: -- temperature-dependent diffraction patterns (theta:2theta, rocking curves) for C18 and C8 CsPbBr3 nanocrystal superlattice samples;-- room temperature diffraction patterns (theta:2theta, rocking curves) for C6, C8, C10, C12, and C18 CsPbBr3 nanocrystal superlattices;in all files, first column is angle in degrees and the second column is intensity.

Användningen av kontanta pengar minskar och allt fler betalningar görs digitalt. Detta är en global förändring, men den är ovanligt tydlig just i Sverige. Det blir allt vanligare att kollektivtrafiken, affärer och andra serviceställen inte tar emot kontanter som betalningsmedel. Möjligheten att betala räkningar med kontanter över disk är högst begränsad; i stora delar av Sverige finns den inte all

Sammanfattning:Denna berättelse om immunoterapi kombinerad med ultrahypo-fraktionerad strålterapi har sitt ursprung i den kliniska studie som på engelska benämdes "Brain Immune Gene Tumour Therapy" (BRIGTT) som professor Leif G, Salford i Lund initierade strax innan 2000-millienium-skiftet. Ett specifikt tumörvaccin framställdes baserat på tumörceller som han extraherade ur tumörvävnad från den gl

In this study, a report is prepared on significantly low specific contact resistivity of alloyed and non-alloyed ohmic contacts fabricated on an as-grown n+-GaN layer and measured with the transfer length method. A low ρc = 8 × 10−8 Ω cm2 is extracted for the alloyed Ti/Al/Ni/Au, and ρc = 4 × 10−7 Ω cm2 for the unannealed Ti/Pd/Au. To achieve these, a highly doped n+-GaN layer with ND = 1.5 × 1019

Advancing the use of air-sensitive polar organometallic Grignard and organolithium reagents under more environmentally benign conditions, here we report the addition of these reagents to a-b unsaturated ketones and aldehydes using the deep eutetic solvent (DES) choline chloride (ChCl): glycerol (Gly) (1:2), under air. Reactions occur at room temperature within seconds with excellent regioselective

Introduction: The Swedish Sleep Apnea Registry (SESAR) collects clinical data from individual obstructive sleep apnea (OSA) patients since 2010. SESAR has recently been integrated with additional national healthcare data. The current analysis presents the SESAR structure and representative clinical data of a national sleep apnea cohort. Methods: Clinical data from unselected patients with a diagno

Flera stora byggprojekt pågår och planeras i Sverige, varav flera är skattefinansierade. Det ligger därför i både samhällets och byggbranschens parters intresse att utveckla kunskapen kring hur stora byggprojekt organiseras och leds, aktat de många samhällsförändringar som Sverige genomgått de senaste decennierna. Denna studie har följaktligen studerat hur olika samhällsförändringar påverkat förut

We show that a profinite group, in which the centralisers of non-trivial elements are metabelian, is either virtually pro-p or virtually soluble of derived length at most 4. We furthermore show that a prosoluble group, in which the centralisers of non-trivial elements are soluble of bounded derived length, is either soluble or virtually pro-p.

Generic statements play a crucial role in concept learning, communication and education. Despite many efforts, the semantics of generics remain a controversial issue, as they do not seem to fit our standard theories of meaning. In this article, we attempt to shed light on this problem by focusing on how these sentences function in reasoning. Drawing on a distinction between property and diagnostic

Inequality is ubiquitous in time and space. It is often measured simply as differences in incomes between various groups, but the phenomenon is more complex than so. Inequality is a many-faceted phenomenon that manifests itself in a number of ways. It shows up in a variety of contexts, for example gender, age, origin, ethnicity, disability, sexual orientation, class, religion and place. The presen

Traditional methods for measuring chemical exposure have challenges in terms of obtaining sufficient data; therefore, improved methods for better assessing occupational exposure are needed. One possible approach to mitigate these challenges is to use self-monitoring methods such as sensors, diaries, or biomarkers. In the present study, a self-monitored method for measuring soot exposure, which inc
