    Abstract In this article, we explore the tension between the significance of touch as a vital sensory modality of human experience and how, with the ongoing coronavirus pandemic, proximity and (tactile) intimacy with other bodies in urban and domestic spaces becomes fraught with the risk of viral contagion. Informed by haptic media studies, the corporeal or sensory turn in contemporary theory, and phenomenology-informed mobile media studies, we examine the possible impacts for mobile device use of the risks of viral contagion associated with our routinized uses of haptic interfaces. We also examine the role and possibility of mobile haptics and the touchscreen in these contexts, and our capacity-via embodied and material metaphor-to extend corporeal reach through the mobile interface. Our contention is that, while the "stand in" for touch that mobile media offers may be perpetually incomplete, the "as-if" structure of habitual experience can play a significant role in narrowing the sensorial gap.

    Abstract Reverse osmosis (RO) membranes represent a strategic tool for the development of desalination and water treatment processes. Today's global needs for clean water supplies show stressing circumstances to secure this supply, relying upon desalination and wastewater treatment and reuse, especially in Egypt and the Middle East. However, chlorine attack and fouling of polyamide layers, the active (selective) layers of RO membranes, are representing a great obstacle to seriously spreading the use of this technology. One promising way of fouling control and chlorine resistance is surface modification using grafting by plasma or vacuum ultraviolet (VUV) irradiation as a layer-by-layer assembly on polyamide membranes. Several studies have shown the effect of grafting by plasma using methacrylic acid (atmospheric pressure plasma) and showed that grafted coatings can improve PA membranes toward permeation compared with commercial ones with fouling behavior but not chlorine resistance. In this work, the techniques of layer-by-layer (LBL) assembly for previously prepared PA RO membranes (3T) using a mixed-base polymer of polysulfone and polyacrylonitrile in the presence of nanographene oxide (GO) without chemical grafting and with chemically grafted poly-methacrylic acid (3TG) were used. Membranes 3T, 3TG, a blank one (a base polymer membrane only was surface modified using VUV activation (AKT), and one with a grafted layer with polyethylene glycol (VUV-PEG) were prepared. These were then compared with polydimethylsiloxane (VUV-PDMS) and another surface modification with low-pressure plasma using acrylic acid (acryl) and hexadimethyl siloxane (GrowPLAS). The tested membranes were evaluated by short-term permeation and salt rejection experiments together with fouling behavior and chlorine resistance. A clear improvement of chlorine resistance and antifouling was observed for 3T membranes under plasma treatment, especially with the grafting with polyacrylic acid. Better antifouling and antichlorine behaviors were achieved with the vacuum UV treatment.

    Abstract: It is well known that solid-organ transplant recipients (SOTRs) have a 65- to 100-fold increase in the risk of developing skin cancer, namely, nonmelanoma skin cancers (NMSCs) such as cutaneous squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC) ...

    Abstract It is well known that solid-organ transplant recipients (SOTRs) have a 65- to 100-fold increase in the risk of developing skin cancer, namely, nonmelanoma skin cancers (NMSCs) such as cutaneous squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC). In addition, these patients are also at increased risk for development of melanoma as well as other less common cutaneous malignancies (Merkel's cell carcinoma, Kaposi's sarcoma). SOTRs with NMSC (namely cSCC) are also at significantly increased risk of poor clinical outcomes including local recurrence, nodal and distant metastasis, and disease-specific death relative to patients who are not immunosuppressed. Increased surveillance and monitoring in patients at risk of aggressive disease and poor outcomes who are on immunosuppression is essential in patients with lung transplants given the high degree of immunosuppression. Increased awareness of risks, treatments, and management allows for improved outcomes in these patients. This article will provide an overview of the risk factors for the development of cutaneous malignancies in organ transplant recipients as well as a detailed discussion of various immunosuppressant and prophylactic medications used in this patient population that contribute to the risk of developing cutaneous malignancies, with an emphasis on NMSC (cSCC and BCC) in lung transplant recipients. Finally, this article includes a discussion on the clinical and dermatologic management of this high-risk immunosuppressed population including a review of topical and systemic agents for field therapy of actinic damage and chemoprevention of keratinocyte carcinomas. In addition, indications for additional treatment and preventive measures such as adjuvant radiation treatment after surgical management of cutaneous malignancies and potential modification of immunosuppressive medication regimens are discussed.

    Abstract Deliberate practice-based medical education has demonstrated superiority in trainee acquisition and maintenance of skills in several surgical subspecialties. In an effort to highlight the impact of a deliberate practice-based surgical curriculum on the technical proficiency of dermatology residents, a prospective cohort study including first- and second-year dermatology residents was performed. A total of 87.5% (7 of 8) first-year dermatology residents completed three hands-on simulations at 6-week intervals. Additionally, six of eight (75.0%) second-year dermatology residents at the same institution were evaluated at a single point-in-time session without accessing the surgical curriculum prior. A 5-point global rating scale (GRS) was used to assess resident performance on six core surgical techniques. Nonparametric ANOVA statistical methods using the Kruskal-Wallis test was performed. The residents' overall GRS increased from a median of 1-2.75 after completion of the curriculum (p < 0.01). There was a significant improvement in the median scores of each tested surgical technique. The first-year residents had a greater overall GRS after completion of the curriculum compared to the second-year residents (median of 2.13 versus 1.88, p < 0.001). Limitations include the small sample size and lack of a synchronized control group. Our study highlights the use of deliberate practice-based strategies as an effective modality in teaching surgical skills to dermatology residents.

    Abstract Selling fair-trade products can be problematic because of their higher price when compared with conventional alternatives. We propose that one way to solve this problem is to make consumers aware of the benefits of fair-trade. To this end, we perform three experimental studies to show that partitioned pricing (PP), which explicitly displays fair-trade as a separate price component, increases consumers' purchase intention toward the fair-trade product. This effect can be explained by increased perceptions of price fairness, which itself is mediated through transparency (but only if an additional verbal justification of the fair-trade price component is present). In the absence of such a verbal justification, recalled prices instead of transparency explain the positive effect of PP on consumers' purchase intentions. Interestingly, boundary conditions of this effect barely exist. Our incentive-aligned study illustrates that PP is associated with a 20% increase in purchases of fair-trade products. The results demonstrate an opportunity to increase the market share of fair-trade products, which increases social welfare and sustainability.

    Abstract Das Ziel des Gesamtprojekts besteht darin, die Herstellkosten von Elektromotoren fuer die E-Mobilitaet zu senken und den Wirkungsgrad zu steigern. Dafuer soll ein neuartiges Klebpaketierverfahren zur Herstellung von Stator- und Rotorpaketen erarbeitet werden, das sich durch eine im Stanzwerkzeug integrierte Einzelblechverklebung im Pressentakt auszeichnet. Ziel des IFAM ist die Untersuchung und Erforschung geeigneter Materialien und Fertigungstechniken fuer innovative Elektrobleche und deren Klebpaketierung. Hierfuer werden einerseits neuartige plasmapolymere Beschichtungen fuer Elektrobleche und deren Prozesstechnik untersucht, andererseits Klebstoffsysteme, Applikations- und Haertungstechniken analysiert und erprobt, die den angestrebten innovativen Stanzklebpaketierprozess erst ermoeglichen. Schliesslich arbeitet das IFAM bei der Umsetzung der Techniken und dem Aufbau von Testelektromotoren mit.
