The Influence of Anaerobic Digestion Effluents (ADEs) Used as the Nutrient Sources for Chlorella sp. Cultivation on Fermentative Biogas Production

Purpose This study investigated the chemical characteristics and anaerobic digestion of Chlorella sp. microalgae cultivated on various anaerobic digestion effluents (ADEs) as a nutrient medium. Chlorella sp. was grown in anaerobically digested effluent of dairy wastewater (DW), municipal wastewater sludge (WS), maize silage and swine slurry, and cattle manure (CM). Methods To ...

Conformational flexibility and pseudosymmetric aggregation in a betainium salt hydrate

The cation of 3-(trimethylammonium)-benzoic acid exhibits a considerable conformational flexibility connected to the orientation of carboxyl group, coupled to the proton position, and rotations of the trimethylammonium group. This conformational flexibility considerably affects the aggregation of ions and molecules of 3-(trimethylammonium)-benzoic acid iodide hydrate, which ...

Aggregate–disaggregate approach to an airfreight forwarder’s planning under uncertainty: a case study

Resource planning of airfreight forwarders is a complex endeavor, requiring decisions to be made in a dynamic and uncertain environment. Airfreight forwarders acquire airfreight spaces from three sources: allotment from carriers, retail from carriers and subcontracting to partners, all of which differ in terms of cost, flexibility and timing of booking. This real-life problem has ...

Groups of module automorphisms and Krull dimension and codimension

Let M be a module over the ring R and G a subgroup of \(\hbox {Aut}_{\mathrm{R}}\hbox {M}\). There has been interest of late in conditions on R, M and G such that one of [M, G] and \(\hbox {M}/\hbox {C}_{\mathrm{M}}(\hbox {G})\) small ensures that the other is also small. Here we consider when the Krull dimension (resp. codimension) of one of these bounds the Krull dimension (resp. ...

Novels as Social Media: How Literature Helped Shape Notions of Sexual Liberation

In the historiography of sexual liberation, the role of cultural artefacts like novels and films has either been taken for granted or not received much attention at all. This article discusses these cultural dimensions of sexual liberation, using the Netherlands as a case study, arguing that these dimensions are important to research in order to better understand the ...

Automaticity of Attentional Bias to Threat in High and Low Worriers

Individuals with high levels of worry are more likely than others to attend to possible threats, although the extent of top-down attentional control processes on this bias is unknown. We compared the performance of high (n = 26) and low worriers (n = 26) on a probe discrimination task designed to assess attention to threat cues, under cognitive load or no-load conditions. The ...

Drinking water contamination and treatment techniques

Water is of fundamental importance for life on earth. The synthesis and structure of cell constituents and transport of nutrients into the cells as well as body metabolism depend on water. The contaminations present in water disturb the spontaneity of the mechanism and result in long/short-term diseases. The probable contaminations and their possible routes are discussed in the ...

Quantization of Time-Like Energy for Wave Maps into Spheres

In this article we consider large energy wave maps in dimension 2+1, as in the resolution of the threshold conjecture by Sterbenz and Tataru (Commun. Math. Phys. 298(1):139–230, 2010; Commun. Math. Phys. 298(1):231–264, 2010), but more specifically into the unit Euclidean sphere \({\mathbb{S}^{n-1} \subset\mathbb{R}^{n}}\) with \({n\geq2}\), and study further the dynamics of the ...

Application of Whole-Genome Prediction Methods for Genome-Wide Association Studies: A Bayesian Approach

Data that are collected for whole-genome prediction can also be used for genome-wide association studies (GWAS). This paper discusses how Bayesian multiple-regression methods that are used for whole-genome prediction can be adapted for GWAS. It is argued here that controlling the posterior type I error rate (PER) is more suitable than controlling the genomewise error rate (GER) for ...

Health Implications of an Immigration Raid: Findings from a Latino Community in the Midwestern United States

Immigration raids exemplify the reach of immigration law enforcement into the lives of Latino community members, yet little research characterizes the health effects of these raids. We examined the health implications of an immigration raid that resulted in multiple arrests and deportations and occurred midway through a community survey of a Latino population. We used linear ...

Chemisorption of air CO2 on cellulose: an overlooked feature of the cellulose/NaOH(aq) dissolution system

A natural abundance of the air CO2 in NaOH(aq) at low temperature was investigated in terms of cellulose-CO2 interactions upon cellulose dissolution in this system. An organic superbase, namely 1,8-diazabicyclo[5.4.0]undec-7-ene, DBU, known for its ability to incorporate CO2 in carbohydrates, was employed in order to shed light on this previously overlooked feature of NaOH(aq) at ...

The Relationship Between Body Weight and Motor Skill Competence in Hispanic Low-SES Preschool Children

The purpose of this study was to investigate the relationship between motor competence and BMI in Hispanic preschool children from low SES backgrounds. One hundred and forty-eight Hispanic low SES preschool children (male = 81, female = 67 participated in this study. All children were measured on gross and fine motor competence using the Peabody Developmental Motor Scales-2 ...

P-splines with derivative based penalties and tensor product smoothing of unevenly distributed data

The P-splines of Eilers and Marx (Stat Sci 11:89–121, 1996) combine a B-spline basis with a discrete quadratic penalty on the basis coefficients, to produce a reduced rank spline like smoother. P-splines have three properties that make them very popular as reduced rank smoothers: (i) the basis and the penalty are sparse, enabling efficient computation, especially for Bayesian ...
