The Recovery and Synthesis of Polyhydroxyalkanoates in the Process of Nitrogen and Phosphorus Removal in Low-Carbon Sewage Based on pH and Nitrogen and Phosphorus Restriction Under Anaerobic-Oxygen Limited Process

Polyhydroxyalkanoate (PHA) is a new type of bio-polyester which is expected to replace traditional petroleum-based plastics. It is also a critical transformation hub of carbon source in nitrogen and phosphorus removal in sewage. Based on the anaerobic-oxygen limited process, the experiment took organic solid waste fermentation liquid as carbon source control hub and realized PHA synthesis and recovery in denitrification and phosphorus removal from low carbon sewage the SBR reactor by regulating pH value and nitrogen and phosphorus restriction. The experimental results showed that when the ratio of C/N and C/P was 150, the content of PHA accounted for 50.39% and 36.07 of the dry cell weight, respectively. Besides, it was found that increasing the C/N ratio was beneficial to increasing the proportion of PHV in PHA. This study proved the feasibility of using an anaerobic-oxygen limited process to recover PHA in nitrogen and phosphorus removal from low-carbon sewage, which saves gas and reduces energy consumption. At the same time, it also provides some help for the follow-up study of low-carbon urban sewage nitrogen and phosphorus removal coupled with resource recovery of PHA to guide the water industry economy to develop in a circular and sustainable direction
Rapid of

as Pneumococcus meningococcus and haemophilus. These bacteria have a polysaccharide capsule, which evades ingestion by most macrophages and enhances their pathogenicity.2 Specialised dendritic macrophages however, have evolved within the marginal zone of the spleen, and these have the ability to take up and present carbohydrate antigens,3 which are commonly of the T cell independent type. Evidence from studies on animals shows that a specialised subset of B cells, capable of responding to carbohydrate, exists in close proximity to the marginal zone macrophages.4 This subset of B cells is nonrecirculating and resides in the spleen. Gaps in the adjacent endothelium allow direct contact between these specialised immune cells and the blood. Thus it can be seen that the spleen is optimally developed to police the blood for the presence of dangerous encapsulated pathogens. This explains why the response to infections with encapsulated bacteria or to vaccination with pneumococcal vaccines is inadequate after splenectomy as the response by lymph node macrophages is insufficient. Unless a splenunculus is present the patient is permanently vulnerable to such encapsulated pathogens. It is well known that postsplenectomy sepsis can be fatal in as little as 12 hours from the onset of symptoms: medical attention, however well informed, may arrive too late. It is therefore my belief that it is the responsibility of the physician or surgeon who recommends splenectomy to discuss the implications with the patient, explaining that lifelong prophylaxis with penicillin will be needed and that pneumococcal vaccine will be given before the operation, although the vaccine may only be beneficial for five years. The family doctor should also be alerted. I have found that, provided the risks and benefits of splenectomy are clearly explained, patients comply very carefully with prophylaxis with penicillin. For those allergic to penicillin, alternatives are available.
Bandwidth Enhancement of Unidirectional Planar Antenna Using Closely Spaced Reactive Loading Technique

In this paper a broadband unidirectional planar microstrip antenna is presented. The proposed geometry consists of rectangular loop having two gaps and metallic strips. Although, the rectangular loop in the geometry introduces a good directionality but offers a narrow bandwidth. This problem is addressed by placing the metallic strips which induce a new resonant frequency results in the improvement of impedance bandwidth. The geometry was optimized using Ansoft’s HFSS which is commercially available electromagnetic (EM) software, and tested practically to validate the simulation results. The measured results indicate 66.57% impedance bandwidth with good gain across the band. Measured results fairly agree with the simulated data.
The Medical Assessment of a New Soft Body Armor

Abstract : The development of a new lightweight soft body armor appears to lower the morbidity and mortality from certain ballistic threats. 'Impulse' -type blunt injuries have been produced in laboratory animals. The severity of underlying injury (if any) did not correlate with the seemingly innocent skin lesion seen behind the armor. Therefore, in the case of impact on a soft body armor, it is recommended that: (1) All victims of assault should be hospitalized for observation in spite of an apparent state of good health and a minimal skin lesion; (2) Strikes to the chest should be monitored with serial chest X-rays; (3) Strikes to the precordial region require cardiac monitoring and serial ECG's and enzyme determinations; and (4) Strikes to the abdomen require frequent examination for signs of peritoneal irritation. Impacts over the liver should be viewed with great suspicion of underlying hepatic injury. (Author)
Take Me Home, Protein Roads: Structural Insights into Signal Peptide Interactions during ER Translocation

Cleavable endoplasmic reticulum (ER) signal peptides (SPs) and other non-cleavable signal sequences target roughly a quarter of the human proteome to the ER. These short peptides, mostly located at the N-termini of proteins, are highly diverse. For most proteins targeted to the ER, it is the interactions between the signal sequences and the various ER targeting and translocation machineries such as the signal recognition particle (SRP), the protein-conducting channel Sec61, and the signal peptidase complex (SPC) that determine the proteins’ target location and provide translocation fidelity. In this review, we follow the signal peptide into the ER and discuss the recent insights that structural biology has provided on the governing principles of those interactions.
Design of a Novel 60 GHz Millimeter Wave Q-Slot Antenna for Body-Centric Communications

The 60 GHz band is a great prospect to meet the future demand for short-range indoor communication requiring wide bandwidth and high data rates. This paper presents the design of a 60 GHz printed Q-slot patch antenna for body-centric communication. The Q-slot has a slot gap of 0.2 mm and is etched on a 6.5 mm × 11 mm rectangular patch. The slotted patch is mounted on an FR-4 (Flame Retardant) substrate that is 1.6 mm thick and has a relative permittivity of 4.3. With a partial ground plane of length of 2.2 mm, the antenna’s overall dimension is 12.9 mm × 14 mm × 1.6 mm. Computer Simulation Technology (CST) microwave studio was used to design and simulate the antenna. In free space, the antenna is resonant at 60.06 GHz with an impedance bandwidth of 12.11 GHz. At 60 GHz, the antenna’s radiation efficiency is 82.15%, with a maximum gain of 8.62 dBi. For further analysis, parametric changes were made to observe the effect on return loss, radiation efficiency, and gain. The antenna was simulated on a three-layer human torso phantom for the on-body scenario. The antenna’s resonant frequency shifted slightly to the right at 2 mm distant from the phantom while maintaining a very wide impedance bandwidth. At this point, the antenna’s radiation efficiency dropped to 56.68% and gradually increased to 74.04% at 10 mm. The maximum gain remained largely unaffected, but some grated radiation patterns were observed.
Sequential effects in facial attractiveness judgments: Separating perceptual and response biases

ABSTRACT When items are presented sequentially, the evaluation of the current item is biased by both the previous item’s value (perceptual bias) and the previous response given (response bias). While these biases have been identified in judgements of facial attractiveness, it is unclear as to whether they produce assimilation and/or contrast effects. Here, two tasks were employed to measure each bias in isolation. By presenting a preceding face without collecting a response, perceptual biases could be investigated, while response biases were considered by requesting a preceding response without presenting a face. Our results demonstrated a perceptual bias in which attractiveness ratings given to the current face shifted away from the baseline attractiveness value of the previous face, while we found no evidence of a response bias due to the previously selected value. These findings highlight the utility in considering sequential biases separately when trying to determine the nature of these effects.
Seed Dormancy and Pre-Harvest Sprouting in Rice—An Updated Overview

Pre-harvest sprouting is a critical phenomenon involving the germination of seeds in the mother plant before harvest under relative humid conditions and reduced dormancy. As it results in reduced grain yield and quality, it is a common problem for the farmers who have cultivated the rice and wheat across the globe. Crop yields need to be steadily increased to improve the people’s ability to adapt to risks as the world’s population grows and natural disasters become more frequent. To improve the quality of grain and to avoid pre-harvest sprouting, a clear understanding of the crops should be known with the use of molecular omics approaches. Meanwhile, pre-harvest sprouting is a complicated phenomenon, especially in rice, and physiological, hormonal, and genetic changes should be monitored, which can be modified by high-throughput metabolic engineering techniques. The integration of these data allows the creation of tailored breeding lines suitable for various demands and regions, and it is crucial for increasing the crop yields and economic benefits. In this review, we have provided an overview of seed dormancy and its regulation, the major causes of pre-harvest sprouting, and also unraveled the novel avenues to battle pre-harvest sprouting in cereals with special reference to rice using genomics and transcriptomic approaches.
Modern Carbon–Based Materials for Adsorptive Removal of Organic and Inorganic Pollutants from Water and Wastewater

Currently, a serious threat for living organisms and human life in particular, is water contamination with persistent organic and inorganic pollutants. To date, several techniques have been adopted to remove/treat organics and toxic contaminants. Adsorption is one of the most effective and economical methods for this purpose. Generally, porous materials are considered as appropriate adsorbents for water purification. Conventional adsorbents such as activated carbons have a limited possibility of surface modification (texture and functionality), and their adsorption capacity is difficult to control. Therefore, despite the significant progress achieved in the development of the systems for water remediation, there is still a need for novel adsorptive materials with tunable functional characteristics. This review addresses the new trends in the development of new adsorbent materials. Herein, modern carbon-based materials, such as graphene, oxidized carbon, carbon nanotubes, biomass-derived carbonaceous matrices—biochars as well as their composites with metal-organic frameworks (MOFs) and MOF-derived highly-ordered carbons are considered as advanced adsorbents for removal of hazardous organics from drinking water, process water, and leachate. The review is focused on the preparation and modification of these next-generation carbon-based adsorbents and analysis of their adsorption performance including possible adsorption mechanisms. Simultaneously, some weak points of modern carbon-based adsorbents are analyzed as well as the routes to conquer them. For instance, for removal of large quantities of pollutants, the combination of adsorption and other methods, like sedimentation may be recommended. A number of efficient strategies for further enhancing the adsorption performance of the carbon-based adsorbents, in particular, integrating approaches and further rational functionalization, including composing these adsorbents (of two or even three types) can be recommended. The cost reduction and efficient regeneration must also be in the focus of future research endeavors. The targeted optimization of the discussed carbon-based adsorbents associated with detailed studies of the adsorption process, especially, for multicomponent adsorbate solution, will pave a bright avenue for efficient water remediation.
Propulsion and Power Rapid Response Research and Development (R&D) Support. Task Order 0011: JP-8+100 Development History and Maintenance Benefits

Abstract : JP-8+100 was introduced into the field in 1994. Since that time, JP-8+100 has received limited acceptance due to a lack of solid engineering information and scientific fact regarding use and limitations of the additive Spec-Aid(registered trademark) 8Q462. As a result, no official Air Force position has ever been established regarding the additive's use or non-use. In 2006, Senior Leader for Propulsion, Ted Fecke convened and tasked an IPT to formulate and recommend a supportable Air Force position regarding the use of JP-8+100 in Air Force Weapons Systems. In fulfillment of that tasking, the IPT has collected all relevant available technical and scientific information about JP-8+100 and has formulated a supportable position based on these facts. In conclusion, this report documents field data and maintenance experience supporting the use of JP-8+100 additive technology in all Air Force Weapon Systems using JP-8.
State of the Art in Hepatic Dysfunction in Pregnancy

Hepatic dysfunction in pregnant women is always challenging for the obstetrician, as the spectrum of hepatic abnormalities can be very large and have various implications, both for mother and fetus. There is a diagnostic and therapeutic polymorphism of hepatic dysfunction in pregnancy and insufficient knowledge related to the etiopathogenesis and epidemiology of this disease. The clinical forms of hepatic dysfunction encountered in pregnancy can vary from liver diseases related to pregnancy (e.g., HELLP syndrome, intrahepatic cholestasis, hyperemesis gravidarum, or acute fatty liver of pregnancy) to de novo ones occurring in pregnancy, and pre-existing liver disease (cholelithiasis, Budd–Chiari syndrome, and cirrhosis). We performed a systematic literature search over 10 years. The review protocol assumed a search of two databases (PubMed®/MEDLINE and Web of Science Core Collection). The strategy regarding the management of these diseases involves multidisciplinary teams composed of different specialists (obstetricians, gastroenterologists and anesthetists) from specialized tertiary centers. Despite the improving prognosis of pregnant women with liver diseases, the risk of maternal–fetal complications remains very high. Therefore, it is necessary to ensure careful monitoring by a multidisciplinary team and to inform the patients of the potential risks.
The Vehicle Routing Problem: State-of-the-Art Classification and Review

Transportation planning has been established as a key topic in the literature and social production practices. An increasing number of researchers are studying vehicle routing problems (VRPs) and their variants considering real-life applications and scenarios. Furthermore, with the rapid growth in the processing speed and memory capacity of computers, various algorithms can be used to solve increasingly complex instances of VRPs. In this study, we analyzed recent literature published between 2019 and August of 2021 using a taxonomic framework. We reviewed recent research according to models and solutions, and divided models into three categories of customer-related, vehicle-related, and depot-related models. We classified solution algorithms into exact, heuristic, and meta-heuristic algorithms. The main contribution of our study is a classification table that is available online as Appendix A. This classification table should enable future researchers to find relevant literature easily and provide readers with recent trends and solution methodologies in the field of VRPs and some well-known variants.
Analysis and Mitigation of Electromagnetic Noise in Resonant Cavities and Apertures

Title of Dissertation: ANALYSIS AND MITIGATION OF ELECTROMAGNETIC NOISE IN RESONANT CAVITIES AND APERTURES Lin Li, Doctor of Philosophy, 2004 Dissertation directed by: Associate Professor Omar Ramahi, Mechanical Engineering The trend of low voltage in electronics circuits and boards makes them vulnerable to electromagnetic interference (EMI). Furthermore, higher speed (clock rate) leads to faster switching which increases the potential for higher radiation from circuits and boards. These inevitable trends collectively compromise the electromagnetic compatibility of electronic systems by increasing their electromagnetic susceptibility. In this work, radiation from enclosures and apertures is studies and characterized and radiation mitigation techniques are proposed. High-speed circuit radiation within an enclosure leads to cavity resonance that can have critical impact on other electronic components housed within the same enclosure. The amplified electric field in the enclosure can couple to critical circuits leading to either hard or soft failures. One measure to gauge the resonance of an enclosure is through the determination of S-parameters between certain ports connected to the enclosure. In this work, different numerical methods for efficient prediction of Sparameters are proposed and evaluated for their effectiveness and accuracy. Once an efficient procedure is established for calculating S-parameters, novel topological variations within the enclosure can be tested before manufacturing using accurate numerical prototyping. The proposed numerical S-parameters calculation algorithms are validated by comparison to laboratory measurements. Radiation from resonant apertures present in the walls of enclosures represents a second major source for radiation. In this work, a novel analysis of aperture radiation is presented based on the interpretation of the aperture as a transmission line. Once the transmission line analogy is established, a novel aperture resonance mitigation technique is proposed based on the use of material coating that mimics the behavior of matching loads that typically terminate transmission lines. The technique consists of adding resistive sheets in selected places in, or around the aperture. The effectiveness of the proposed method is demonstrated by first using numerical simulation of an aperture present in an infinite perfectly conducting sheet, and then by designing an experiment where the novel technique proposed here is tested on resonant apertures present in a metallic box. Both radiation measurements in an anechoic chamber and S-parameters measurements were conducted to test the validity of the proposed mitigation techniques.

Enhanced visible-light degradation of organic dyes via porous g-C3N4

Abstract Graphitic carbon nitride (g-C3N4) was prepared by reduction of melamine by adapting a pyrolysis method. Porous g-C3N4 (P-g-C3N4) was synthesized by altering the surface as well as the morphology of g-C3N4 by treating with oxidizing acids (chemical protonation). The photocatalytic activity of g-C3N4 and P-g-C3N4 are estimated by degrading various organic dyes namely methyl blue (MB), crystal violet (CV), and rhodamine B (Rh-B) irradiated under sunlight. The optical absorption edge of g-C3N4 was found to be blue-shifted from 2.7 eV to 3 eV on protonation. The g-C3N4 shows superior photocatalytic degradation efficiency in comparison with pristine g-C3N4. The P-g-C3N4 shows enhanced photocatalytic degradation efficiency of 98%, 99%, and 90% for MB, CV, and Rh-B, respectively, in 180 mins under sunlight irradiation with a rate of the reaction of about 4.046 min−1, 5.951 min−1, and 2.260 min−1. Reactive oxygen species experiments revealed that the production of. ·OH radicals are responsible for the deterioration of dyes. The boosted degradation efficacy of P-g-C3N4 is attributed to an increase in the surface area thereby exposing a large number of active sites for dye degradation. GRAPHICAL ABSTRACT
A Transformer-Based Approach to Multilingual Fake News Detection in Low-Resource Languages

Fake news classification is one of the most interesting problems that has attracted huge attention to the researchers of artificial intelligence, natural language processing, and machine learning (ML). Most of the current works on fake news detection are in the English language, and hence this has limited its widespread usability, especially outside the English literate population. Although there has been a growth in multilingual web content, fake news classification in low-resource languages is still a challenge due to the non-availability of an annotated corpus and tools. This article proposes an effective neural model based on the multilingual Bidirectional Encoder Representations from Transformer (BERT) for domain-agnostic multilingual fake news classification. Large varieties of experiments, including language-specific and domain-specific settings, are conducted. The proposed model achieves high accuracy in domain-specific and domain-agnostic experiments, and it also outperforms the current state-of-the-art models. We perform experiments on zero-shot settings to assess the effectiveness of language-agnostic feature transfer across different languages, showing encouraging results. Cross-domain transfer experiments are also performed to assess language-independent feature transfer of the model. We also offer a multilingual multidomain fake news detection dataset of five languages and seven different domains that could be useful for the research and development in resource-scarce scenarios.
PRIORITIZATION OF BRIDGES FOR SEISMIC RETROFITTING

This report presents a prioritization method developed for seismic retrofitting of bridges. The method is used to identify bridges that are in most need of retrofitting and to rank order these bridges based on vulnerability and importance criteria. Vulnerability assessment includes evaluation of the seismic hazard at the bridge site, classification of existing bridges into bridge classes and fragility analysis. Importance assessment considers the attributes that relate the consequences of failure of a bridge to the public safety and socio-economic well-being of a community. The importance of a bridge is considered to be closely related to its function within the transportation network system. A detailed review and critique of the existing prioritization methodologies is included. An example application is conducted for the Palo Alto, California area.
