Mapplethorpe and the Flower
Authors: Murray Derek Conrad 
Published: June 2020

Mapplethorpe and the Flower: Radical Sexuality and the Limits of Control is the first dedicated book-length critical study of the late artist Robert Mapplethorpe’s flower photographs. The book is an interdisciplinary investigation into the symbolism of the flower as envisioned by a photographer whose production was mired in controversy—triggered in large part by his thematic exploration of radical sexuality and queer subcultural life.
Mapplethorpe came into international prominence due to the public response to his polarizing retrospective exhibition, The Perfect Moment (1989-1990), a ground breaking collection of images exploring three largely traditional genres of photography: the still life, the portrait, and the human figure. If there is one characteristic that unifies the artist’s approach to these genres, however, it is his meticulous attention to the materiality of the photograph as object. Mapplethorpe was a dedicated formalist, committed to locating what is most beautiful about his chosen subject—producing work under carefully controlled studio conditions that enabled the development of a unique and singular aesthetic vision. Bearing this in mind, Mapplethorpe and the Flower is dedicated to unpacking how the artist’s unique brand of formal sophistication and discipline, combined with his conceptual bravado, interpenetrates all of his photographs—and reaches its formal and conceptual maturation in his flower images.
There has been significant critical attention paid to the artist’s more notorious photographs, namely the S&M imagery, and his now infamous persona as provocateur and sexual renegade. Fixation on this dimension of the artist’s mythology overshadows the formal details and interlocking representational and political commitments crosscutting the artist’s oeuvre. Mapplethorpe and the Flower is a recuperative effort: one that seeks to locate persistent threads running through the artist’s seemingly disparate aesthetic and conceptual investigations.
Impact of scale-aware deep convection on the cloud liquid and ice water paths and precipitation using the Model for Prediction Across Scales (MPAS-v5.2)
Authors: Fowler Laura D. , Barth Mary C. , Alapaty Kiran 
Published: June 2020

Abstract. The cloud liquid water path (LWP), ice water path (IWP),
and precipitation simulated with uniform- and variable-resolution numerical
experiments using the Model for Prediction Across Scales (MPAS) are compared
against Clouds and the Earth's Radiant Energy System (CERES) and Tropical
Rainfall Measuring Mission data. Our comparison between monthly-mean model
diagnostics and satellite data focuses on the convective activity regions of
the tropical Pacific Ocean, extending from the Tropical Eastern Pacific
Basin where trade wind boundary layer clouds develop to the Western Pacific Warm Pool characterized by deep convective updrafts capped with extended
upper-tropospheric ice clouds. Using the scale-aware Grell–Freitas (GF) and
Multi-scale Kain–Fritsch (MSKF) convection schemes in conjunction with the
Thompson cloud microphysics, uniform-resolution experiments produce large
biases between simulated and satellite-retrieved LWP, IWP, and
precipitation. Differences in the treatment of shallow convection lead the
LWP to be strongly overestimated when using GF, while being in relatively
good agreement when using MSKF compared to CERES data. Over areas of deep
convection, uniform- and variable-resolution experiments overestimate the
IWP with both MSKF and GF, leading to strong biases in the
top-of-the-atmosphere longwave and shortwave radiation relative to
satellite-retrieved data. Mesh refinement over the Western Pacific Warm Pool
does not lead to significant improvement in the LWP, IWP, and precipitation
due to increased grid-scale condensation and upward vertical motions.
Results underscore the importance of evaluating clouds, their optical
properties, and the top-of-the-atmosphere radiation budget in addition to
precipitation when performing mesh refinement global simulations.

‘Private enforcement’ van nalatigheid bij financieel-economische criminaliteit
Nederland heeft, net als ieder ander land, groot belang bij goed werkende, gereguleerde handelsplatformen. De aantrekkelijkheid van handelsplatformen is mede afhankelijk van de kwaliteit van ‘public and private enforcement’ en juridische mogelijkheden om geschillen te beslechten. De afgelopen periode hebben grote Nederlandse ondernemingen de voorpagina’s van de kranten gehaald door hun (mogelijke) betrokkenheid bij financieel-economische criminaliteit. In deze bijdrage wordt de vraag beantwoord of ‘private enforcement’ van financieel-economische criminaliteit bij ondernemingen wel voldoende resultaat kan opleveren om effectief te zijn en om benadeelde partijen te ondersteunen bij het verhalen van hun schade.
Development of 100 μmol mol−1 Cl2 Standard Gas Mixture for Accurate Calibration of Ambient Cl2 Sensors and Stack Emission Monitors
Authors: Jung Jinsang , Kim ByungMoon , Oh Sanghyub 
Published: June 2020

Abstract
To accurately measure Cl2 mixing ratio using stack emission monitors and leak monitoring sensors in a workplace, it is essential calibrating monitors and sensors periodically using a Cl2 standard gas mixture. Because there is no reliable analytical technique for Cl2, an international standard for high-pressure Cl2 gas mixtures has not been established. A novel approach for the quantification of Cl2 was developed using quadrupole mass spectrometry (QMS) with an expanded uncertainty of 0.7 μmol mol−1. A 100 μmol mol−1 chlorine (Cl2)/N2 gas mixture was produced through a two-step procedure involving dilution of Cl2 with N2 in high-pressure aluminum cylinders. To check the consistency between 100 μmol mol−1 Cl2 gas mixtures in different cylinders, Cl2 gas mixtures were quantified using the QMS based approach. It was found that four cylinders of 100 μmol mol−1 Cl2 gas mixtures prepared in 2016 agreed within 0.7 μmol mol−1. The long-term stability of 100 μmol mol−1 Cl2 gas mixtures was assessed through changes in the Cl2 mixing ratio over a one-year. It was found that the 100 μmol mol−1 Cl2 gas mixture was stable within ±0.7 μmol mol−1 over one year. Finally, 100 μmol mol−1 Cl2/N2 gas mixture was successfully developed in a high pressure cylinder with an expanded uncertainty of 2.0 μmol mol−1 (k = 2; 95% confidence level).
Imperfection of the World Trade Organization as a Hazard for International Business
Authors: Zoladkiewicz Krystyna , Orłowska Renata 
Published: June 2020

This paper examines the negative impact of the paralysis observed in the World Trade Organization (WTO) functioning on international business. We provide an overview of the loopholes in the WTO rules and principles which became serious threats for the multilateral trading system. Our research identifies important loopholes in the MFN clause, DSB and Appellate Body. We bring clarity that the paralysis observed in the WTO functioning is a consequence of these factors. The deviations and exceptions of the WTO rules permit the WTO members to compete “unfairly”. China is among the economies which are the most efficient in this respect. We term China’s behaviour on the global market as “economic factitious disorder”. It can be explained as permanently maintaining the status of a developing country by China and using preferences for LDCs despite a really high level of economic development. These findings indicate that the WTO lacks the mechanism to react and to prevent such abuses. They were not envisaged by the WTO creators, which suggests the need of the WTO reform. We contribute to international business research and the international organizations literature by identifying the causes of the paralysis of the WTO functioning.

Authors: Tehseen Rabia , Farooq Muhammad Shoaib , Abid Adnan 
Published: June 2020

Fuzzy Expert System (FES) with application to earthquake prediction has been presented to reproduce the performance of a human expert in earthquake prediction using expert systems. This research aims to predict future earthquakes having a magnitude 5.5 or greater. Previous earthquake data from 2000 to 2019 have been collected for this purpose. Since the earthquake data for the specified region have been reported on different magnitude scales, suitable relationships were determined to obtain uniform data. The uniform data have been used to calculate seismicity indicators according to the guidelines provided by Gutenberg-Richter’s scale for quantitative determination of earthquake features. The relationships among these seismic indicators have been used by the human expert to set the rule base of Fuzzy expert system. These rules have been mathematically validated and tested on instrumentally recorded earthquake data. The results obtained from the proposed FES presented 47 % accuracy in predicting future earthquakes that may occur in the 100 km radial area from 34.708 ° N, 72.5478 ° E.

This paper presents results of research on the effectiveness of bi-directional voice transmission in a 6 kV mine cable network using BPL-PLC (Broadband over Power Line - Power Line Communication) technology. It concerns both emergency cable state (supply outage with cable shorted at both ends) and loaded with distorted current waveforms. The narrowband (0.5 MHz–15 MHz) and broadband (two different modes, frequency range of 3 MHz–7.5 MHz) transmission efficiency, considered as an objective study, was correlated with the level of noise in the cable for both induction-inductive and mixed capacitive-inductive coupling of the measurement devices and/or modems. The quality of voice transmission, considered as a subjective study, was assessed by a group of 15 people aged between 25 and 35 years old. The test audio signals included samples in 3 languages sourced from ITU (International Telecommunication Union) and processed in 3 bitrates ranging from 8 kbps to 24 kbps.

Comparative metabolomic analyses of Dendrobium officinale Kimura et Migo responding to UV-B radiation reveal variations in the metabolisms associated with its bioactive ingredients
Authors: Chen Yue , Shen Qi , Lv Ping , Sun Chongbo 
Published: June 2020

Background
Dendrobium officinale Kimura et Migo, a member of the genus Dendrobium, is a traditional Chinese medicine with high commercial value. The positive roles of UV-B radiation on active ingredient metabolism in various medicinal plants have been studied. However, the metabolic responses of D. officinale stems to UV-B treatment is largely unknown.

Methods
An untargeted metabolomics method was used to investigate the metabolic variations in D. officinale stems between the control and UV-B treatments.

Results
In total, 3,655 annotated metabolites, including 640 up- and 783 down-regulated metabolites, were identified and grouped into various primary metabolic categories. Then, a number of metabolites involved in the polysaccharide, alkaloid and flavonoid biosynthesis pathways were identified. For polysaccharide biosynthesis, several intermediate products, such as pyruvate, secologanate, tryptophan and secologanin, were significantly up-regulated by the UV-B treatment. For polysaccharide biosynthesis, many key fundamental building blocks, from the glycolysis, starch and sucrose metabolism, and fructose and mannose metabolism pathways, were induced by the UV-B treatment. For flavonoid metabolism, accumulations of several intermediate products of chalcone synthase, chalcone isomerase and flavanone 3-hydroxylase were affected by the UV-B treatment, indicating an involvement of UV-B in flavonoid biosynthesis. The UV-B induced accumulation of polysaccharides, alkaloids and flavonoids was confirmed by HPLC analysis. Our study will help to understand the effects of UV-B on the accumulation of active ingredients in D. officinale.

In the treatment (T2) two rows of Maize sown after 15 rows of Mungbean, the lowest mean population of whitefly 7.03 per plant was recorded which was followed by 7.42 whitefly per plant in the treatment (T4) with two rows of Sorghum after 15 rows of Mungbean. In barrier crops, the lowest disease incidence of 28.94% was recorded in the treatment (T2), two rows of maize after 15 rows of Mungbean. The mean seed yield recorded was 6.75 q/ha. The treatment (T2), two rows of Maize after 15 rows of Mungbean was recorded to be effective in the management of MYMV disease. The lowest mean whitefly population of 4.71 per plant was recorded in the above treatment, Mungbean sown with Maize in 4:2 ratio. Mungbean sown with Maize in 4:2 ratio was recorded to be efficacious in the management of MYMV disease. The results indicated that the barrier crop of maize interfered with the movement of vector whiteflies.

Introduction: Hibiscus sabdariifa is a natural dye, generally called roselle. Most of Synthetic dye have been established to cause toxicity. The aim of this research was to determine the staining effect of different concentration of Hibiscus sabdariffa extracts at various pH, duration on fungal staining.
Methods: Standard Gomori’s metenaine silver stains as control and Hibiscus sabdariffa extracts (alcoholic and aqueous) were used to stain a fungal (Aspergillus spp) positive lung tissue, using various concentration (5% and 10%) of the extract, with change of pH achieved by treating the extracts with ammonium hydroxide and glacial acetic acid at various duration (30 seconds and 1 hour respectively), each was used for staining Aspergillus spp in tissue section as a primary stain replacing (4% Chromic acid, sodium metabisulphite, Hexamine working silver solution and Sodium thiosulphate).
Results: All extracts after treatment were acidic, the fungi were best demonstrated with Aqueous hibiscus stains (5% untreated, 10% untreated and 5% glacial acetic acid treated) at longer duration, staining the capsule, light to dark-brown in a light-green background when compared with the alcoholic hibiscus stain. Few of the alcoholic hibiscus stains show metachromatic property. The Hibiscus stains stained better at longer duration and the change of pH was indirectly proportional to the staining ability of the hibiscus stains.
Conclusion: The results obtained indicate that hibiscus plant extract have the potential for use in the morphological identification of fungi in formalin-fixed paraffin-embedded tissue section.

Co‐expression with chaperones can affect protein 3D structure as exemplified by loss‐of‐function variants of human prolidase
Authors: Wątor Elżbieta , Rutkiewicz Maria , Weiss Manfred S. , Wilk Piotr 
Published: June 2020

Prolidase catalyzes the cleavage of dipeptides containing proline on their C terminus. The reduction in prolidase activity is the cause of a rare disease named 'Prolidase Deficiency'. Local structural disorder was indicated as one of the causes for diminished prolidase activity. Previous studies showed that heat shock proteins can partially recover prolidase activity in vivo. To analyze this mechanism of enzymatic activity rescue, we compared the crystal structures of selected prolidase mutants expressed in the absence and in the presence of chaperones. Our results confirm that protein chaperones facilitate the formation of more ordered structures by their substrate protein. These results also suggest that the protein expression system needs to be considered as an important parameter in structural studies.DatabasesThe reported crystal structures and their associated structure factor amplitudes were deposited in the Protein Data Bank under the accession codes 6SRE, 6SRF, and 6SRG, respectively.
