An improved conventional-to-micro/minichannel threshold was proposed as Bo = 4 and BoRe(1)(0.5) = 200, where Bo is the Bond number and Re-1 is the liquid Reynolds number. The region Bo < 4 and BoRe(1)(0.5) < 200 is termed as micro/minichannel because bubbles tend to be confined and elongated in the channel and the conventional two-phase flow theory loses its applicability. Flow-pattern based heat
This work deals with a detailed analysis of the vibrational spectra of methoxy (CH3O-) and ethoxy (CH3CH2O-) on W(110) and Cu(100) single crystal surfaces. By using theoretical ab initio quantum mechanical modeling, it is demonstrated that an unprecedented quantitative understanding of the vibrational frequencies of a surface adsorbate can be obtained. A qua
The secondary structure of proteins is crucial for proper function of the protein in biological systems. Peptide T, an octapeptide from the envelope glycoprotein gp120 of the HIV virus, has previously been shown to be responsible for binding to the CD4 receptor on T helper/inducer lymphocytes. NMR studies showed that the four C-terminal amino acid residues of peptide T adopted a beta-turn conforma
This chapter reassesses the modernization processes at work in Republican China during the Warlord period between 1911 and 1927 by focusing on corporate, public action by non-state interest groups and organizations. In particular, it looks at modes of corporate governing at the interface of business/economy and education: the realm of vocational education. The chapter examines a particularly illum
Popular Abstract in Swedish Bröstcancer är den vanligast förekommande cancerformen hos kvinnor. Under sin livstid kommer tio procent av den kvinnliga befolkningen att få bröstcancer men endast en minoritet kommer att avlida av den. Operation är den vanligaste behandlingen och kombineras oftast med strålbehandling. Armlymfödem samt nedsatt axelrörlighet och muskelstyrka är välkända sidoeffekter tilTen percent of the female population in Sweden will be diagnosed with breast cancer during their lifetime, but only a minority will die from the disease. Arm lymph oedema is a well-known complication following breast cancer treatment and the incidence varies between about 10% when axillary node dissection is performed and about 40% when axillary radiotherapy is added. The general aim of this thes
Popular AbstractStudien är ett försök att analysera den sociala konstruktionen av "medievåld" i den svenska pressdebatten 1980-1995. Totalt analyserades 1029 artiklar ur sju av Sveriges största dags- och kvällstidningar. Många artiklar refererar till vetenskapliga "bevis" att våld i medierna föder faktisk aggression. En närmare analys av medieeffektforskningen avslöjar dock att det påstådda sambanThis study is an attempt to analyze the social construction of media violence in the Swedish press debate 1980-1995. Altogether, 1029 articles from seven of Sweden's biggest daily and evening papers were qualitatively analyzed. Numerous claims refer to scientific 'proof' that media violence breeds personal aggression. However, a critical examination of the media effects research reveal that the al
Popular Abstract in Swedish För analys av agroekosystems näringsämnescirkulation presenteras här en generell modell. I centrum står födoproduktionsintensitet, mänsklig bärförmåga, uthållighet och effektivitet. Modellen kan användas på system med flera markanvändningstyper och är därför lämpad för studier i olika skalor. Jämförelser av alla slags agroekosystem, oavsett tid och rum, är möjliga. OlikThis study presents a general model for analysing nutrient cycling in agroecosystems. The focus is on food production intensity, human carrying capacity, sustainability and efficiency. The model can be used on systems including different kinds of land uses, which makes it applicable for studies on different scales. Comparisons of all kinds of agroecosystems, independent of time and place, are made
Coal is used to generate electricity and produce high-value chemicals through coal gasification, liquefaction, and coke. During combustion sulfur is released, which leads to acid rain formation. Mineral matter present in coal is undesirable because it causes technological problems such as corrosion of equipment and reduction of overall rate of combustion of coal. Also, after combustion, the minera
Wetlands provide many benefits, such as water storage, flood control, transformation and retention of chemicals, and habitat for many species of plants and animals. The ongoing degradation of wetlands in the Great Lakes basin has been caused by a number of factors, including climate change, urbanization, and agriculture. Mapping and monitoring wetlands across such large spatial and temporal scales
During the last 10 years, the mobile phone and the emergence of websites, such as Youtube, which facilitate user-generated content, have enabled an explosion of pictures and video clips posted on the internet by civilians documenting the activities of authority figures. This “sousveillance” is a kind of inverse surveillance, reciprocal to surveillance, where members of the grassroots monitor those
The transdisciplinary argument in this article is that the social and ecological unsustainability of modern, globalized capitalism ultimately derives from the design of its central artifact: what Polanyi called all- or general-purpose money. The notion of a singular measure of economic value is a peculiar cultural conception that is inherently at odds with physical reality, yet it pervades modern
In this retrospective cohort study of 193 consecutive subjects with primary mitochondrial disease (PMD) seen at the Children's Hospital of Philadelphia Mitochondrial Medicine Frontier Program, we assessed prevalence, severity, and time of onset of sensorineural hearing loss (SNHL) for PMD cases with different genetic etiologies. Subjects were grouped by genetic diagnosis: mitochondrial DNA (mtDNA)
Soil bulk density (BD) is a parameter dependent on soil texture, compositions of soil minerals and organic matter and the extent of soil compaction. Seasonal freeze/thaw in arid areas with shallow groundwater tables (AASGT) may significantly change BD and hence soil hydrothermal properties and water holding capacity. Therefore, quantifying soil bulk density changes (BDC) under freeze/thaw conditio
BACKGROUND: Sorbitan sesquioleate (SSO) is a sorbitan fatty acid ester, an emulsifier used in topical products and certain patch test preparations. SSO may affect the patch test results. It has been debated whether to include the substance in the baseline series to avoid misinterpretation of the results.OBJECTIVES: To report the prevalence and simultaneous reactions of SSO with other patch test pr
Adverse childhood experiences (ACE) and high levels of disinhibition have been associated with a variety of negative outcomes such as aggressive antisocial behavior (AAB). However, forensic psychiatric populations remain an understudied group in this field of research. This study aimed to fill that gap by investigating associations between ACE, AAB, and disinhibition in a forensic psychiatric samp
Premixed laminar flat non-stretched flames of methyl acetate + air have been studied at atmospheric pressure. The heat flux method was employed to stabilize the flames over equivalence ratios ɸ = 0.7–1.5 at initial gas temperatures from 298 to 348 K. The laminar burning velocities of methyl acetate + air mixtures have been measured at these conditions and compared with the literature data. Laser-i
PACs (polycylic aromatic compounds) are air pollutants formed in incomplete combustion, e.g., in vehicle engines. Vegetation can potentially remove substantial amounts and act as bioindicators of these pollutants. Increased knowledge of the pollutant removal efficiencies of different tree species is essential for understanding the potential benefits trees can provide urban residents. We investigat
Rationale & Objective: There is a dearth of data characterizing patients receiving kidney replacement therapy (KRT) for kidney failure due to systemic lupus erythematosus (SLE) and their clinical outcomes. The aim of this study was to describe trends in incidence and prevalence of KRT among these patients as well as to compare their outcomes versus those of patients treated with KRT for diseas
Nondisplaced or minimally displaced femoral neck fractures are commonly treated with internal fixation, because of its less invasive and less time-consuming nature, as well its retention of the biological properties of the hip. Internal fixation with screws or pins is the current clinical routine in Sweden. However, the authors of some recent studies in elderly patients have suggested that the use
The introduction of a child day-care system is one of the early welfare interventions targeted towards mothers and young children that over time gained great prominence in the Swedish welfare state. Because quantitative research on day-cares in historical settings is generally scarce, in this study, we focus on the determinants of day-care enrolment in southern Sweden during the early twentieth ce
