BACKGROUND: Factor affecting sperm retrieval rate (SRR) or pregnancy rates (PR) after testicular sperm extraction (TESE) in patients with non-obstructive azoospermia (NOA) have not been systematically evaluated. In addition, although micro-TESE (mTESE) has been advocated as the gold standard for sperm retrieval in men with NOA, its superiority over conventional TESE (cTESE) remains conflicting. OB
1. In rat isolated hepatic arteries contracted with phenylephrine, acetylcholine and the calcium ionophore A23187 each elicit endothelium-dependent relaxations, which involve both nitric oxide (NO) and endothelium-derived hyperpolarizing factor (EDHF). However, the contribution of prostanoids to these responses, and the potential interaction between EDHF and other endothelium-derived relaxing fact
Animals across phyla can detect early cues of infection in conspecifics, thereby reducing risk of contamination. It is unknown, however, if humans can detect cues of sickness in people belonging to communities with whom they have limited or no experience. To test this, we presented Western faces photographed two hours after the experimental induction of an acute immune response to one Western and
The chapter analyses the question whether scientific performance can be measured appropriately and if the measurement may create suitable performance incentives for the research units. For this purpose, the outcome of a large dataset including different scientific fields is examined in detail. A major point of investigation is to show the effect of specific instruments of New Public Management (NP
Automation is a collection of a whole set of theories and methods to make a system work automatically as intended, in our case the urban water supply system. A critical feature of automation is the feedback principle: a sensor is measuring a certain variable, e.g. a concentration; a computer tests that the measurement is valid; a computer algorithm calculates and decides what should be corrected;
What is sex work? I have decided to start this short contribution with a question, which I think the reader should answer before continuing. So what is sex work? Is it a legitimate form of work or is it a job whose only characteristics are exploitation, harassment, and coercion? Also, can a person (woman or man) freely decide to be a sex worker or is it impossible to engage in such profession with
The integrity of isolated mitochondria can be estimated functionally using enzymatic activities or the permeability of mitochondrial membranes to molecules of different sizes. Thus, the permeability of the outer membrane to the protein cytochrome c, the permeability of the inner membrane to protons, and the permeability of the inner membrane to NAD+, NADH and organic acids using soluble matrix deh
A model-based predictive controller known as Dynamic Matrix Control with Linear Programming optimizer (DMC-LP) is applied to a nonlinear multivariable laboratory process which consists of four interconnected water tanks. Experimental results show that DMC-LP is a powerful constrained model predictive controller. Based upon simple step response model, it can provide improved control performance and
How do you control a superintelligent artificial being given the possibility that its goals or actions might conflict with human interests? Over the past few decades, this concern– the AGI control problem– has remained a central challenge for research in AI safety. This paper develops and defends two arguments that provide pro tanto support for the following policy for those who worry about the AG
The production of biobutanol is hindered by the product's toxicity to the bacteria, which limits the productivity of the process. In situ product recovery of butanol can improve the productivity by removing the source of inhibition. This paper reviews in situ product recovery techniques applied to the acetone butanol ethanol fermentation in a stirred tank reactor. Methods of in situ recovery inclu
The TFM-DYN model represents a significant advancement from static flow accumulation estimations into dynamic hydrological modeling (Nilsson et al., 2021). It incorporates variable precipitation in time and space as input together with high-resolution topography and includes functions for friction and infiltration to produce results such as water depths, flow velocity, inundated areas, flow pathwa
How do nondescript spaces of transfer (Warped Space), as such, relate to the wide-spread headphone culture in those spaces? To address this question, the chapter presents a reading of Vidler (1999) on Warped space, Simmel (the Stranger) and Bull (2012) on Toxic Audiotopia. The chapter concludes that Warped spaces or spaces of transfer call for people not to connect, and it was also found that this
Background: Obtaining reliable data under explicit evaluations is one of the most complicated challenges in assessing drug users' status. Respondents are likely to give answers that are to their advantage or deliberately deceitful. Regarding drug use, intense and inevitable drug craving is known as one of the main causes of relapse and treatment failure. As a matter of fact, drug craving is direct
I FBL 3 kap. 1 och 5 §§ finns de allmänna lämplighetsvillkoren för en fastighet respektive de ekonomiska krav som ställs för jord – och skogsbruksfastigheter. Dessa villkor gäller vid ombildning eller nybildning av en fastighet och vid en servitutsåtgärd. Undantaget från dessa lämplighetsvillkor finns i FBL 3 kap. 9 § som säger att ”Fastighetsbildning får äga rum, även om fastighet som nybildas elIn the real property formation act 3 chap. 1 and 5 §§ you will find the general conditions of suitability for a property unit and the financial requirements for agricultural - and forestry property units. These conditions should be fulfilled in every conversion or the formation of a property unit and at an easement action. The exception to these conditions is in the real property formation act 3 c
Uganda faces various challenges related to compliance, including tax evasion, regulatory non- compliance, and violations of legal standards, laws, policies and regulations among others. These issues undermine the government's ability to collect revenue, provide public services, and maintain law and order. Enhancing compliance is not only a matter of enforcing penalties but also involves creati
