Effect of Different Ethephon Concentrations on Shiss Removal in ‘Khlass’ and ‘Sukkary’ Date Palm Varieties

After pollination, aborted date fruits known as tricarpel or shiss, remain on the brunch in most of the varieties and exert competition on fruits in water and nutrients. In Sukkary, they drop down at the end of kimri stage, while remain on ‘Khlass’ until the harvest. Most of them remain as bisr and little turns into tamr which is not appreciated in the date market. They can only be used as paste that has low price compared to dates. In an attempt to get rid of shiss, we sprayed Ethephon at different concentrations on bunches of ‘Sukkary’ and ‘Khlass’ after fruit-set, at hababook stage.Together with the shiss drop, a non-desirable fruit drop also occurs. We are looking for the optimum ethephon concentration where shiss dropped more than fruits. In ‘Khlass’, the Ethephon concentration 800 ppm showed the highest shiss drop (81%) together with a fruit drop of 20% that occurs as well, while in ‘Sukkary’, the concentration of 600 ppm was the best by giving shiss drop equal to 44%together with a fruit drop equal to 12%. We consider that the concentration of 800 ppm at hababook stage is the ideal concentration to generate an optimum drop in shiss with a reasonable percentage of fruit drop. We, therefore highly recommend a trial with this concentration on ‘Sukkary’ as well.
A shielded QMSIW ultra-compact self-diplexing antenna for WiMAX/WLAN applications

In this contribution, novel design is presented for a very compact shielded quarter-mode substrate-integrated waveguide (S-QMSIW) based self-diplexing antenna (SDA) for WiMAX/WLAN applications. In order to achieve dual-band features, a slot is etched onto the top of the metal. Two orthogonal microstrip feed lines in the full-wave EM-simulator (HFSS) simulate the S-QMSIW resonator at two different frequencies (3.45 and 5.45 GHz). The proposed antenna pattern is extremely adaptable, allowing for simple frequency adjustments for each resonant frequency. A lumped circuit model is expected to be used to assess the antenna structure. A self-diplexing antenna based on S-QMSIW was designed, fabricated and tested to claim the proposed concept. At 3.45 and 5.45 GHz, the proposed antenna peak gains are 4.7 and 5.6 dBi, respectively. It offered port isolation better than 38 dB. The antenna front-to-back ratio was greater than 19.5 dB in each band. The proposed antenna circuit size was very compact ( ).
Modeling and design of an electrically pumped SiGeSn microring laser

We present a suspended SiGeSn microring laser design that enables strain relaxation of the material layer stack, electrical pumping and adequate heat sinking. Using both strain and composition as two degrees of freedom to engineer the band structure, a direct bandgap is obtained in the gain material of a double heterostructure layer stack, and the L- to Γ-valley energy difference increased to 78 meV, by 66% compared to a non-underetched structure. The temperature dependent current threshold is modeled for the designed device and determined to be 18 kA/cm2 at 50 K. The fabrication process is outlined and first experimental electroluminescence results indicating the effectiveness of our approach are reported. At the time this proceedings paper is being submitted, electrically pumped lasing has also been achieved with a similar structure, with results that will be reported in a future publication.
Soft Switching Multiphase Interleaved Boost Converter with High Voltage Gain for EV Applications

In this paper, a soft switching interleaved boost converter (SS-IBC) using auxiliary resonant circuit for electric vehicles (EV) applications is proposed. Several phases of the proposed converter can be connected to make a multiphase interleaved boost converter. The operation of multiphase interleaved boost converter is identical to that of the one phase boost converter. All phases are ideally identical with shifted control signals and are controlled by PWM control strategy of equal switching frequency and duty cycle. The proposed converter can be considered as a cost effective retrofit to the grid integrated battery charging applications. It affords a steady electrical power for the load not only from the utility or classical energy storage systems as batteries, but also from renewable energy systems like photovoltaic (PV), wind or fuel cell systems. An appropriate design example demonstrates the size of the design circuit components and parameters are investigated. Analysis, design, and simulation of the presented converter are verified using PSIM simulation software on an 8.2 kW setup system with a conversion efficiency more than 97% over a wide output power conversion range from rated power to a minimum power of 460 W with complete soft switching operation. The converter performance is also validated experimentally on a downsized hardware rated 1.0 kW and the maximum efficiency is found to be 98.78%.
A Spatial Relationship Preserving Adversarial Network for 3D Reconstruction from a Single Depth View

Recovering the geometry of an object from a single depth image is an interesting yet challenging problem. While previous learning based approaches have demonstrated promising performance, they don’t fully explore spatial relationships of objects, which leads to unfaithful and incomplete 3D reconstruction. To address these issues, we propose a Spatial Relationship Preserving Adversarial Network (SRPAN) consisting of 3D Capsule Attention Generative Adversarial Network (3DCAGAN) and 2D Generative Adversarial Network (2DGAN) for coarse-to-fine 3D reconstruction from a single depth view of an object. Firstly, 3DCAGAN predicts the coarse geometry using an encoder-decoder based generator and a discriminator. The generator encodes the input as latent capsules represented as stacked activity vectors with local-to-global relationships (i.e., the contribution of components to the whole shape), and then decodes the capsules by modeling local-to-local relationships (i.e., the relationships among components) in an attention mechanism. Afterwards, 2DGAN refines the local geometry slice-by-slice, by using a generator learning a global structure prior as guidance, and stacked discriminators enforcing local geometric constraints. Experimental results show that SRPAN not only outperforms several state-of-the-art methods by a large margin on both synthetic datasets and real-world datasets, but also reconstructs unseen object categories with a higher accuracy.
Modeling Intra‐ and Interannual Variability of BVOC Emissions From Maize, Oil‐Seed Rape, and Ryegrass

Air chemistry is affected by the emission of biogenic volatile organic compounds (BVOCs), which originate from almost all plants in varying qualities and quantities. They also vary widely among different crops, an aspect that has been largely neglected in emission inventories. In particular, bioenergy‐related species can emit mixtures of highly reactive compounds that have received little attention so far. For such species, long‐term field observations of BVOC exchange from relevant crops covering different phenological phases are scarcely available. Therefore, we measured and modeled the emission of three prominent European bioenergy crops (maize, ryegrass, and oil‐seed rape) for full rotations in north‐eastern Germany. Using a proton transfer reaction–mass spectrometer combined with automatically moving large canopy chambers, we were able to quantify the characteristic seasonal BVOC flux dynamics of each crop species. The measured BVOC fluxes were used to parameterize and evaluate the BVOC emission module (JJv) of the physiology‐oriented LandscapeDNDC model, which was enhanced to cover de novo emissions as well as those from plant storage pools. Parameters are defined for each compound individually. The model is used for simulating total compound‐specific reactivity over several years and also to evaluate the importance of these emissions for air chemistry. We can demonstrate substantial differences between the investigated crops with oil‐seed rape having 37‐fold higher total annual emissions than maize. However, due to a higher chemical reactivity of the emitted blend in maize, potential impacts on atmospheric OH‐chemistry are only 6‐fold higher.
Analyzing the Cultural Contradictions of Authenticity: Theoretical and Managerial Insights from the Market Logic of Conscious Capitalism

This research analyzes the cultural contradictions of authenticity as they pertain to the actions of consumers and marketers. The authors’ conceptualization diverges from the conventional assumption that the ambiguity manifest in the concept of authenticity can be resolved by identifying an essential set of defining attributes or by conceptualizing it as a continuum. Using a semiotic approach, the authors identify a general system of structural relationships and ambiguous classifications that organize the meanings through which authenticity is understood and contested in a given market context. They demonstrate the contextually adaptable nature of this framework by analyzing the authenticity contradictions generated by the cultural tensions between “conscious capitalism”—a market logic that encompasses both global brands and small independent businesses, such as a farm-to-table restaurant or an organic food co-op—and the elitist critique. The Slow Food movement provides a case study for analyzing how consumers, producers, and entrepreneurs who identify with conscious capitalist ideals understand these disauthenticating, elitist associations and the strategies they use to counter them. The authors conclude by discussing implications of the analysis for theories of authenticity and for managing the authenticity challenges facing conscious capitalist brands.
Two sides of the same coin: adaptation of BCIs to internal states with user-centered design and electrophysiological features

The ideal brain–computer interface (BCI) adapts to the user’s state to enable optimal BCI performance. Two methods of BCI adaptation are commonly applied: User-centered design (UCD) responds to individual user needs and requirements. Passive BCIs can adapt via online analysis of electrophysiological signals. Despite similar goals, these methods are rarely discussed in combi-nation. Hence, we organized a workshop for the 8th International BCI Meeting 2021 to discuss the combined application of both methods. Here we expand upon the workshop by discussing UCD in more detail regarding its utility for end-users as well as non-end-user-based early-stage BCI development. Furthermore, we explore electrophysiology-based online user state adaptation concerning consciousness and pain detection. The integration of the numerous BCI user state adaptation methods into a unified process remains challenging. Yet, further systematic accumula- tion of specific knowledge about assessment and integration of internal user states bears great potential for BCI optimization.
The Role of Nitric Oxide in Stem Cell Biology

Nitric oxide (NO) is a gaseous biomolecule endogenously synthesized with an essential role in embryonic development and several physiological functions, such as regulating mitochondrial respiration and modulation of the immune response. The dual role of NO in embryonic stem cells (ESCs) has been previously reported, preserving pluripotency and cell survival or inducing differentiation with a dose-dependent pattern. In this line, high doses of NO have been used in vitro cultures to induce focused differentiation toward different cell lineages being a key molecule in the regenerative medicine field. Moreover, optimal conditions to promote pluripotency in vitro are essential for their use in advanced therapies. In this sense, the molecular mechanisms underlying stemness regulation by NO have been studied intensively over the current years. Recently, we have reported the role of low NO as a hypoxia-like inducer in pluripotent stem cells (PSCs), which supports using this molecule to maintain pluripotency under normoxic conditions. In this review, we stress the role of NO levels on stem cells (SCs) fate as a new approach for potential cell therapy strategies. Furthermore, we highlight the recent uses of NO in regenerative medicine due to their properties regulating SCs biology.
Enhancement of energy efficient distribution generation integrated with solid state transformer using improved rider optimization algorithm

ABSTRACT Nowadays, the usage of the latest technologies and pure energies like photovoltaic energy, wind energy, and electrical vehicles are increasing in demand to minimise environmental pollution. Hence, to hold this kind of technologies, the distribution systems in the future have to be converted to AC–DC hybrid for considering all kinds of DGs and (DC and AC) of loads. This paper attempts to develop an integration of DG with AC–DC hybrid distribution systems connected with solid state transformer (SST). The main intention of this paper is to make an energy-efficient system, by enhancing the voltage profile, reducing greenhouse gas emissions and reducing real and reactive power losses, when DG with SST is connected to a hybrid distribution system. With these constraints, a multi-objective function is formulated, which is solved by a new improved meta-heuristic algorithm in optimal location and sizing of DG. The new algorithm adopted in this paper is the improved Rider Optimisation Algorithm (ROA) termed as Fitness Rate-based ROA (FR-ROA). The experimental analysis on single and multi-objective functions proves the efficacy of SST in providing an energy-efficient system model.

Effect of Oral Nutritional Supplementation on National Institute of Health Stroke Scale in Acute Ischemic Stroke

BACKGROUND: Approximately, 6-31% of nutritional deficits are present before the stroke and worsen during hospitalization. Besides affecting the patient’s physical and mental abilities, stroke can also cause a decrease in nutritional status, which has a major influence on the rate of death and disability. One intervention to overcome stroke patients’ nutritional problems is giving oral nutritional supplementation. The role of oral nutritional supplementation in stroke severity in patients with acute ischemic stroke has not yet been extensively studied. AIM: This study aimed to evaluate the effect of oral nutritional supplementation on the National Institute of Health Stroke Scale (NIHSS) in patients with acute ischemic stroke. METHODS: This was an experimental study with a pre- and post-study group method. Twenty-eight patients with acute ischemic stroke were referred to Adam Malik General Hospital, Medan, Indonesia, and were allocated randomly into two groups. Fourteen patients as control group received the normal hospital diet and 14 patients as intervention group received normal hospital diet plus oral nutritional supplementation for 7 days. The NIHSS scores were assessed on the first day and the eighth day after intervention in each group. RESULTS: There were significant reductions in NIHSS scores between day 1 and day 8 in both groups (p < 0.001). The mean delta NIHSS scores were −2.28 ± 1.63 and −2.57 ± 1.98 in the intervention and control groups, respectively. There was no significant difference in NIHSS scores between the intervention and control groups (p = 0.682). CONCLUSION: The effect of oral nutritional supplementation significantly reduced the NIHSS scores in acute ischemic stroke, but there was no significant difference compared to the normal hospital diet.
The Predictive Power of Near-Infrared Spectroscopy in Improving Cognitive Problems in Patients Undergoing Brain Surgeries: A Systematic Review

One of the main objectives in neurosurgical procedures is the prevention of cerebral ischemia and hypoxia leading to secondary brain injury. Different methods for early detection of intraoperative cerebral ischemia and hypoxia have been used. Near-infrared spectroscopy (NIRS) is a simple, non-invasive method for monitoring cerebral oxygenation increasingly used today. The aim of this study was to systematically review the brain monitoring with NIRS in neurosurgery. The search process resulted in the detection of 324 articles using valid keywords on the electronic databases, including Embase, PubMed, Scopus, Web of Science, and Cochrane Library. Subsequently, the full texts of 34 studies were reviewed, and finally 11 articles (seven prospective studies, three retrospective studies, and one randomized controlled trial) published from 2005 to 2020 were identified as eligible for systematic review. Meta-analysis was not possible due to high heterogeneity in neurological and neurosurgical conditions of patients, expression of different clinical outcomes, and different standard reference tests in the studies reviewed. The results showed that NIRS is a non-invasive cerebral oximetry that provides continuous and measurable cerebral oxygenation information and can be used in a variety of clinical settings.
The Negative Photoconductivity of Ag/AgO Grown by Spray-Pyrolysis

The main goal of this work is to provide a general description of the negative photoconductivity effect observed in Ag/AgO films grown by the spray-pyrolysis technique. X-ray diffractograms display hybrid films with high texturized AgO and metallic Ag phases. Scanning electron microscopy images show small Ag particles on the surface. Due to its surface nature, X-ray photoelectron spectroscopy revealed the predominance of the metallic character of Ag 3d spectra as compared to Ag2+. Negative photoconductivity with photoresponse in the order of seconds is observed under several wavelengths of excitation. We found that the amplitude of the negative photoresponse is strongly dependent on the optical absorbance and enhanced by surface plasmon resonance. The low-cost technique employed and the special features regarding negative photoconductivity provide an exciting platform for developing optical-electronic devices with low power consumption.
Expansión punitiva y tratamiento para agresores sexuales: a propósito de la inhabilidad de la Ley 1918 de 2018 y la sentencia C-407 de 2020

El 12 de julio de 2018 se promulgó la Ley 1918, mediante la cual se establece el régimen de inhabilidades a quienes hayan sido condenados por delitos sexuales cometidos contra menores. Esta norma fue objeto de estudio por la Corte Constitucional (sentencia C-407 de 2020), tribunal que declaró exequible esta inhabilidad, en el entendido de que su duración deberá sujetarse a los límites temporales que para dichas penas establezca el Código Penal colombiano. En el presente documento ofrecemos una mirada alternativa en torno al tema, para lo cual iniciamos nuestro estudio con la expansión punitiva en materia de delitos sexuales. Posteriormente abordamos el tratamiento que se les da a los agresores sexuales desde una mirada comparativa e interdisciplinar, para desembocar en el análisis de constitucionalidad de esta medida, cuya aplicación demanda una clasificación del delincuente, que es omitida en el ámbito nacional. Nuestra tesis, contrario al pronunciamiento de constitucionalidad del 16 de septiembre de 2020 –que es vinculante y de obligatorio cumplimiento–, es que la Ley 1918 de 2018 es inconstitucional y no supera el test de proporcionalidad, razón por la cual debió ser expulsada del ordenamiento jurídico colombiano.
Quality Assessment of Zingiber officinale Roscoe Essential Oil from Nepal

Zingiber officinale Roscoe rhizome plays a vital role in food flavoring as well as utilization in folk medicine. Nepal is categorized among the leading countries of Z. officinale rhizome production and export. Mature Z. officinale rhizome collection is based on the major production sites within Nepal, but we are currently unaware of the chemical composition of essential oil for export. A comparative investigation of Z. officinale rhizome essential oil compositions, collected from 12 different sites of the eastern, mid, and western regions of Nepal, has been carried out. The analysis of essential oils chemical composition by gas chromatographic–mass spectral (GC-MS), enantiomeric composition by chiral gas chromatography–mass spectrometry (CGC-MS), and antimicrobial activity was evaluated. Essential oil yields ranged from 0.28% to 0.34%. The results showed that the essential oils obtained in this study contained α-zingiberene (8.6%-24.1%), camphene (7.2%-12.8%), β-phellandrene (3.8%-10.1%), neral (0.6%-11.8%), geranial (1.0%-17.4%), ar-curcumene (3.0%-10.3%), and β-sesquiphellandrene (3.7%-9.7%). With CGC-MS, the enantiomeric distributions of 21 chiral compounds were determined and showed no contrasting enantiomeric distributions. Two essential oil samples (G3 and G5) possessed good antibacterial activity against Pseudomonas aeruginosa (MIC = 78.1μg/mL) and excellent antifungal activity against Aspergillus niger (MIC = 39.1 μg/mL). Based on the content of α-zingiberene and citral (neral and geranial), samples collected from their respective areas might be used to identify an ideal Z. officinale rhizome production zone in Nepal.

The Interplay between Autophagy and Virus Pathogenesis—The Significance of Autophagy in Viral Hepatitis and Viral Hemorrhagic Fevers

Autophagy is a process focused on maintaining the homeostasis of organisms; nevertheless, the role of this process has also been widely documented in viral infections. Thus, xenophagy is a selective form of autophagy targeting viruses. However, the relation between autophagy and viruses is ambiguous—this process may be used as a strategy to fight with a virus, but is also in favor of the virus’s replication. In this paper, we have gathered data on autophagy in viral hepatitis and viral hemorrhagic fevers and the relations impacting its viral pathogenesis. Thus, autophagy is a potential therapeutic target, but research is needed to fully understand the mechanisms by which the virus interacts with the autophagic machinery. These studies must be performed in specific research models other than the natural host for many reasons. In this paper, we also indicate Lagovirus europaeus virus as a potentially good research model for acute liver failure and viral hemorrhagic disease.
