Challenges Facing Industrial Analytical Labs Many routine QC/QA laboratories can perform material analyses with single range, basic Fourier transforminfrared (FT-IR) instrument configurations. However, modern analytical laboratories face increasing workloads from a broad range of sample types with a simultaneous drive for faster results and more complex sample characterization needs. Flexibilit...

Transposition is a multistep process in which a transposable element DNA sequence moves from its original genetic location to a new site. Early steps in this process include the formation of a transposition complex in which the end sequences of the transposable element are brought together in a structurally precise fashion through the action of the element-encoded transposase protein and the cl...

Infrared (IR) spectroscopy is used extensively to characterize the chemical composition of trace evidence such as paints, fibers and adhesives as well as seized drugs and related chemicals. We have recently introduced the Thermo ScientificTM iSTM50 ATR module, a novel, extended-range attenuated total reflectance (ATR) module that is integrated into the NicoletTM iS50 FT-IR spectrometer. This in...

Solid dose drugs comprise a considerable segment of the pharmaceutical market. The solid dose form can offer long shelf life, convenient drug delivery, and can be packaged into capsules, tablets, gel caps, and patches. Polymorphism is the ability of a molecule to exist in more than one stable or meta-stable crystalline state. Distinct crystalline forms commonly exhibit differences in pharmacolo...

En el desarrollo de actividades mineras, tanto a cielo abierto como en subterráneo, es importante determinar ciertas propiedades las rocas, presentes los afloramientos encontrados, una ellas la resistencia compresión simple (RCS), ya que mediante esta y otras in situ, se puede evaluar estabilidad estructuras. La RCS evalúa envío permanente muestras laboratorio, lo cual muchas veces tedioso, com...

ficus benjamina commonly known as the weeping fig or benjamin's fig, is a species of moraceae, native to south and southeast asia and australia. it is a topiary tree reaching 15 metres in height in natural conditions. ficus benjamina is planted as a potted plant and as an ornamental shrub in gardens in mazandaran and elsewhere in the country. stem and crown gall symptoms were observed on f...

A low resolution Not I physical map of Escherichia coli was recently constructed. In this report we demonstrated that this map can be used to map Tn5 and F insertions physically. The transposon, Tn5, contains Not I recognition sequences in its IS50 sequences. F plasmid contains an unmapped Not I site. Hence, the location of Tn5 and F in the chromosome can be mapped by identifying the location o...
