Concepts of industrial diafiltration systems

The use of diafiltration as part of ultrafiltration processes on an industrial scale is now the state-of-the-art in the food & beverage, biotech and pharma industry for the recovery of fermentation broth. In this paper the advantages and disadvantages of the most common process modes of diafiltration - batch and continuous - will be discussed. Further, the new concept of counter-current diafil

Kinetics of the gas‐phase reactions of chlorine atoms with CH²F², CH³CCl³, and CF³CFH² over the temperature range 253–553 K

Relative rate techniques were used to study the title reactions in 930–1200 mbar of N2 diluent. The reaction rate coefficients measured in the present work are summarized by the expressions k(Cl + CH2F2) = 1.19 × 10−17 T2 exp(−1023/T) cm3 molecule−1 s−1 (253–553 K), k(Cl + CH3CCl3) = 2.41 × 10−12 exp(−1630/T) cm3 molecule−1 s−1 (253–313 K), and k(Cl + CF3CFH2) = 1.27 × 10−12 exp(−2019/T) cm3 molec

N-body Simulation of the Stephan's Quintet

The evolution of compact groups of galaxies may represent one of the few places in the nearby universe in which massive galaxies are being forged through a complex set of processes involving tidal interaction, ram-pressure stripping, and perhaps finally "dry mergers" of galaxies stripped of their cool gas. Using collisionless N-body simulations, we propose a possible scenario for the formation of

Star Formation Laws and Thresholds from Interstellar Medium Structure and Turbulence

We present an analytical model of the relation between the surface density of gas and star formation rate in galaxies and clouds, as a function of the presence of supersonic turbulence and the associated structure of the interstellar medium (ISM). The model predicts a power-law relation of index 3/2, flattened under the effects of stellar feedback at high densities or in very turbulent media, and

Estimation of physical performance and measurements of habitual physical activity may capture men with high risk to fall-Data from the Mr Os Sweden cohort

To evaluate if clinically usable estimates of physical performance and level of habitual physical activity are associated with fall risk in elderly men. A population-based sample of 3014 randomly selected men aged 69-80 years was recruited to medical centers in Gothenburg, Malmoe, or Uppsala. The level of physical activity and self-reported falls during the preceding 12 months was evaluated using

Mission, Money and Power

The term mission in its modern meaning was coined during the expansion of western Christianity which was in many ways entangled with colonialism. The western missionary movement’s modus operandi was adopted by missions from other backgrounds as well, when economic growth and growth of revivalist Christianity have coincided. When the outcome is new churches in economically underprivileged areas, th

Adipocytes and Obesity-Related Conditions Jointly Promote Breast Cancer Cell Growth and Motility : Associations With CAP1 for Prognosis

The global increase in overweight and obesity rates represent pressing public health concerns associated with severe comorbidities, amongst a rising incidence and impaired outcome of breast cancer. Yet, biological explanations for how obesity affects breast cancer are incompletely mapped. Herein, the joint impact by differentiated 3T3-L1 adipocytes and obesity-related metabolic conditions on breasThe global increase in overweight and obesity rates represent pressing public health concerns associated with severe comorbidities, amongst a rising incidence and impaired outcome of breast cancer.

Expression of rat alpha 1-microglobulin-bikunin in baculovirus-transformed insect cells

cDNA encoding rat alpha 1-microglobulin-bikunin was ligated into the transfer vector pVL 1392 and recombined with a wild-type baculovirus. The resulting alpha 1-microglobulin-bikunin-encoding baculovirus was used to infect Trichoplusia ni (Hi-5) insect cells. The infected cells secreted alpha 1-microglobulin with maximal concentrations of 15 mg/liter 5 days after infection. The secreted proteins m

Isolation and characterization of a 14-kDa albumin-binding fragment of streptococcal protein G

Protein G, a streptococcal cell wall protein, has separate binding sites for human albumin and IgG. Streptococci expressing protein G were treated with the bacteriolytic agent mutanolysin. Several IgG- and human serum albumin (HSA)-binding peptides were identified in the material thus solubilized and one of these, a 14-kDa peptide, was found to bind HSA but not IgG in Western blot experiments. Thi

Hippocampus and basal ganglia as potential sentinel sites for ischemic pathology after resuscitated cardiac arrest

Aims of the study: Neurological impairment after resuscitated cardiac arrest (CA) remains a significant unmet medical need. Brain ischemia associated with CA and subsequent reperfusion is evident as two fundamentally different types of damage on neuropathological examination: frank necrosis (involving all cell types) and selective eosinophilic neuronal death (SEND). These types of damage are not o

Persuasive Design and Targeting of insurgents in International Law

The U.S. counterinsurgency – symbolised by the omnipresent killing eye of drones – as it expands from the battlefield to the monitor, is criticised for inaugurating a geographically unbounded war that subjects the everyday life of a population to wartime targeting calculation. We, however, claim that the significant feature of the so-called new technologies of looking and targeting is in their abi

Naturalization in a context of free mobility: Evidence from cross-national data on Finnish immigrants in Sweden

Using unique longitudinal microdata linking administrative records from Sweden and Finland, we study how immigrant naturalization relates to cultural proximity. We analyze how Swedish citizenship acquisition depends on mother tongue by comparing Swedish-speaking and Finnish-speaking immigrants from Finland, who arrived in Sweden in 1988–2004, and contrast with other Nordic-born immigrants. We trea

Differential expression of viral agents in lymphoma tissues of patients with ABC diffuse large B-cell lymphoma from high and low endemic infectious disease regions

Diffuse large B-cell lymphoma (DLBCL), the most common type of non-Hodgkin’s lymphoma (NHL) in adults, accounts for approximately 30-40% of newly diagnosed lymphomas worldwide. Environmental factors, such as viruses and bacteria, may contribute to cancer development through chronic inflammation and the integration of oncogenes, and have previously been indicated in cervical cancer, hepatocellular
