PROGRESS IN THE MICROBIAL REMEDIATION STRATEGIES FOR OIL CONTAMINATED SITES: A REVIEW

The natural crude oil community is a valuable resource for bioremediation of pollutant environments. The hydrocarbonoclastic bacteria naturally present can adapt to different aquatic sources, and when exposed to a hydrocarbon source can promptly commence degradation. Bioremediation, a process that use microorganisms to degrade oils that cause serious environmental and human problems. Bioremediation processes typically involve microbes which act either singly or consortium to complete the degradation process. Both in situ (in place) and ex situ (removal and treatment in another place) remediation approaches are used. The versatility of microbes to degrade a variety of oils makes bioremediation a technology that can be applied in different environmental conditions. Though it can be inexpensive and in situ approaches can reduce disruptive engineering practices, bioremediation is still not a common practice. There are many advantages to be gained from a quick clean-up of an oil spill, some of which relate not to the marine ecosystem, but to other concerns. These include economic impacts from lost us of shorelines for recreation, legal liabilities and settlement of claims, and aesthetic considerations. Besides, rapid oil disappearance may lead seashores and beaches safer for local wildlife and minimized the movement of undegraded oil from the beaches into the water column.

Secure Federated Feature Selection

In this paper, we propose a secure federated feature selection protocol, whose core is a secure federated χ 2 -test protocol, namely F ED - χ 2 . In F ED - χ 2 , we recast χ 2 -test, a correlation test, as a second frequency moment estimation problem and use stable projection to encode the local information in a short vector. As such encodings can be aggregated with summation, secure aggregation can be applied to conceal the individual updates. We formally establish the security guarantee of F ED - χ 2 by demonstrating that the joint distribution is hidden in a subspace containing exponentially possible distributions. Our evaluation results show that (1) F ED - χ 2 achieves good accuracy with small client-side computation overhead; (2) federated feature selection based on F ED - χ 2 performs comparably to the centralized feature selection with χ 2 -test.
Is Transparency a Potent Weapon for Reputation Building? Malaysian Evidence

Purpose: The purpose of this paper is to investigates the disclosure of reputation by focusing on the transparency of information disclosed in the corporate annual report of Malaysian public listed companies (PLCs). Design/methodology/approach: To achieve this, a content analysis is used to examine reputation disclosure in the annual report of Malaysian PLCs for the year 2018. The sample study comprises 83 PLCs. As a new proxy for the measurement of reputation, a disclosure index was developed and used in the current study. Findings: Items disclosed under leadership, workplace, and citizenship facet are the most popular and high ranked disclosed among Malaysian PLCs while item on the awards received is a least disclosed. Transparency is undeniably a powerful weapon for reputation. Studies show that higher disclosure improved the efficiency of financial markets and the information disclosed influences stakeholders' perceptions of the company's operations, reputation, and preservation of company identity. Research limitations/implications: The findings can be interpreted only across the targeted samples, covering a study period of one year. Practical implications: The findings imply that Malaysian PLCs relied on the precision of the corporate annual report function as a good medium to communicate with their stakeholders. They conceived that the greater transparency, the better reputation they will receive. Originality/value: The current study provides an insight into the literature journey by using the new reputation measurement to shed light on future investigations.

Lead and cadmium removal in synthetic wastewater using constructed wetland

Heavy or toxic metals are harmful to humans and other organism even in small quantities. This research focused on the removal efficiency of the heavy metals (lead and cadmium) using constructed wetland system. Constructed wetlands are the low cost engineered systems that have been designed and constructed to utilize the natural processes involving wetland vegetation, soils, and the associated microbial assemblages to assist in treating wastewaters. In addition, constructed wetland treatment had demonstrated the good capacity in treating the wide range of wastewaters including the hazardous industrial waste. In this research, the free water surface constructed wetland was conducted in the batch mode system and loaded with Pistia stratiotes (water lettuce) in order to study the removal efficiency of cadmium and lead elements. From the study, it was found that the Pistia stratiotes is an aquatic plant that growing rapidly and also a high biomass crop with an extensive root system that can enhance the heavy metals removal. There were two parameters studied in this research which were varying in number of plant, and varying pH conditions. The removal of lead and cadmium in the constructed wetland were increased when the numbers of plant increased. The constructed wetland containing 15-plants recorded the highest removal with 99.28% for lead removal and 65.89% for cadmium removal. For the pH condition experiment, the neutral condition (pH = 7) showed the better removal compared to the base and acidic conditions. As a conclusion, constructed wetland system with wetland plant (Pistia stratiotes) showed good removal efficiency for lead and cadmium from the industrial wastewater.
Design of Folded Rectangular Microstrip Antenna on Thinner Substrate for Broadband and Dual band Dual Polarized Response

— Wideband design of folded structure rectangular microstrip antenna on electrically thinner substrate is discussed. The folded patch portion in the rectangular patch yields the frequency tuning in between TM 10 and TM 20 resonant modes that yields wideband response. The incorporation of folded structure offers half wavelength variation over the antenna aperture that gives broadside radiation pattern across the impedance bandwidth. By exploring the offset feed position, dual band and dual polarized configuration using the same design is obtained, which offers frequency and polarization agility. Based on the analysis carried out, resonant length formulation and design methodology using the two approaches; either based on the band start frequency of the realized bandwidth or fundamental mode frequency of the bottom portion of the folded patch, is presented. Similar antennas designed using them on suspended air and dielectric substrate, are proposed. The folded patch antenna on suspended FR4 substrate in 900 MHz frequency band yields bandwidth of 22.4% with a peak broadside gain of 8.2 dBi, and for the substrate of thickness 0.054  g of the coaxial feed. Against the reported wideband designs, the bandwidth and gain obtained here are larger for the given thinner substrate antenna. In all the proposed configurations, an experimental validation is carried out for the obtained simulated results, which shows close agreement.

Sample characterizations and strength measurements of serpentinite gouges

In this report, we present supporting data relevant to our continuing investigations of the frictional strength of serpentinite. We have measured the strength of chrysotile-, lizardite-, and antigorite-rich serpentinite gouges under hydrothermal conditions. Identification of serpentine minerals was based on X-ray powder diffraction analysis, and petrographic, scanning electron microscope, and electron microprobe techniques were used to fully characterize the samples. Experimental methods and the determination of correction factors, particularly for jacket strength, are outlined in detail; the corrected roomtemperature data are consistent with previous studies. The coefficient of friction, n, of chrysotile gouge is roughly 0.2 at 25 °C, whereas the lizarditeand antigorite-rich gouges are at least twice as strong. The very low roomtemperature strength of chrysotile appears to be a consequence of its high adsorbed water content; when the adsorbed water is removed, chrysotile is as strong as pure antigorite gouge at room temperature. Heating to nearly 200 °C leads to slight to substantial increases in the frictional strengths of all three gouges. The strength increases of chrysotile and, to a lesser extent, of lizardite, are probably caused by the partial loss of adsorbed water upon heating. In addition, all of the heated gouges may have become slightly lithified at the highest temperatures tested. Limited data suggest that different polytypes of a given serpentine mineral have similar strengths; thus, deformation-induced changes in polytype should not affect fault strength. At 25 °C, the chrysotile gouge shows a transition from velocity strengthening at velocities $0.32 nm/s to velocity weakening at velocities £1 \imfs. At elevated temperatures, however, chrysotile-gouge strength is essentially independent of velocity at low velocities. Overall, at a given temperature chrysotile may show a restricted range of velocities over which velocity-strengthening behavior occurs, and this range may shift to progressively higher velocities as temperature increases. Although fewer data are available for the heated lizardite and antigorite gouges, their behavior is consistent with that outlined for chrysotile.
The application of nanoparticles to lessen liquefaction risks: an emerging technique

To lessen the liquefaction risk, soil remediation could be an alternative possibility to eliminate or minimize structural damage and loss of lives during ground motion events. One of the most common approaches for limiting potential deformations of soil following the application of dynamic loads is soil densification. Traditional site stabilizing techniques have limits in terms of full-field treatment, entail extensive disturbance, and are costly to implement. Nanomaterials are being introduced for soil enhancement due to the outstanding advancement of nanotechnology. The current paper summarizes the literature, including the applications of nanoparticles in sand grain densification and future research opportunities. Nanomaterials (particularly colloidal silica, bentonite, and laponite) used in geotechnical engineering are being investigated to study how these nanoparticles improve sand reinforcement. Colloidal silica and bentonite can significantly withstand sand liquefaction due to their distinct rheological properties. Laponite, a very promising nanoparticle, can substantially enhance the liquefaction resistance of sand due to its good rheological properties and relatively small size scale. Nanoparticles have advantages in geotechnical engineering applications in terms of nanomaterial manufacturing and soil property optimization. This study reviews the application of nanoparticles to improve soil quality and comprehend the interaction between nanotechnology and geotechnical engineering by using unique approaches.
Selective genotyping for discovery of QTL controlling flowering time in dolichos bean (Lablab purpureus L.)

: Dolichos bean is grown in environments with short and long crop growth seasons. Development and deployment of cultivars with flowering time (FT) that matches prevailing crop growth season help maximize their productiv - ity in the environments to which they are targeted. Dependable knowledge on genetic basis of FT enables the use of the most appropriate selection strategy to breed cultivars with desired FT. We unraveled the genetic basis by detecting QTL controlling FT using SSR markers following selective genotyping strategy (SGS) in F 2 mapping population (MP). We evaluated the effectiveness of SGS as compared to entire MP genotyping strategy (EGS) to detect QTL controlling FT. Our results suggest that alleles at two SSR markers (LPD 25 and LPD 190) are linked to QTL controlling FT in both SGS and EGS. Our results provide adequate evidence for comparable statistical power of SGS relative to EGS for detection of QTL controlling FT.
Dissolved oxygen and nutrient cycling in chesapeake bay: an examination of controls and biogeochemical impacts using retrospective analysis and numerical models

Title of Document: DISSOLVED OXYGEN AND NUTRIENT CYCLING IN CHESAPEAKE BAY: AN EXAMINATION OF CONTROLS AND BIOGEOCHEMICAL IMPACTS USING RETROSPECTIVE ANALYSIS AND NUMERICAL MODELS Jeremy Mark Testa, Doctor of Philosophy, 2013 Directed By: Professor W. Michael Kemp Marine Estuarine Environmental Sciences Hypoxia, the condition of low dissolved oxygen, is a topic of interest throughout aquatic ecology. Hypoxia has many realized and potential impacts on biogeochemical cycles and animal populations, many of which are negative. The extent and occurrence of hypoxic conditions has been on the rise globally, despite some reductions due to nutrient management success stories. Long-term increases in the volume of bottom-water hypoxia have been observed in Chesapeake Bay. Although there is evidence for the occurrence of low oxygen conditions historically in Chesapeake Bay, including direct observations of anoxia prior to the mid-20 th century large-scale nutrient load increases, hypoxic volume has increased over the last 50 years. Surprisingly, the volume of hypoxia observed for a given nutrient load has doubled since the mid-1980s, suggesting controls beyond nutrient loading. I conducted retrospective data analyses and numerical modeling studies to understand the controls on and consequences of hypoxia in Chesapeake Bay over multiple time and space scales. The doubling of hypoxia per unit TN load was associated with an increase in bottom-water inorganic nitrogen and phosphorus concentrations, suggesting the potential for a positive feedback, where hypoxia-induced increases in N and P recycling support higher summer algal production and subsequent O2 consumption. I applied a sediment biogeochemical model at several stations in Chesapeake Bay, which revealed that hypoxic conditions substantially reduce denitrification and phosphorus sorption to iron oxyhydroxides, leading to the elevated sediment-water N and P fluxes that drive this feedback. An analysis of O2 dynamics during the winter-spring indicate that the day of hypoxia onset and the rate of March-May water-column O2 depletion are most strongly correlated to chlorophyll-a concentrations in bottom water; this suggests that the spring bloom drives early season O2 depletion. Metrics of winter-spring O2 depletion were un-correlated with summer hypoxic volumes, however, suggesting that other controls (including physical forcing and summer algal production) are important. I used a coupled hydrodynamic-biogeochemical model for Chesapeake Bay to discover that summer algal production is necessary to maintain hypoxia throughout the summer, and that nutrient load-induced increases in hypoxia are driven by elevated summer respiration in the water-column of lower-Bay regions.

RESPONSE OF SOME VEGETATIVE INDICATORS OF FABA BEANS TO ORGANIC RESIDUE SOLUTION AND SPRAYING WITH PROLINE

An experiment was conducted during the fall season of 2020 in one of the protected facilities (plastic house) in the Faculty of Agriculture, University of Kufa/Iraq. This research aimed to study the effect of applying three types of decomposing organic residue solution to soil (cow, sheep, and chicken), and foliar spraying of proline with three concentrations (0, 40 and 80) mg·L -1 on some indicators of the vegetative growth of a local variety of faba bean. A factorial experiment was conducted according to R.C. B.D with three replications. The results revealed significant effects of organic residue solution of chicken for plant height 46.03 cm, leaf number 26.10 (leaf·plant -1 ), branch number 4.32 (branch·plant -1 ), and chlorophyll content 44.04 (SPAD unit) in comparison with cow residue solution. Moreover, spraying with proline at 80 mg·L -1 realized a significant increase in leaf number 25.96 (leaf·plant -1 ), branch number 3.73 (branch·plant -1 ), and relative chlorophyll content 34.68 (SPAD unit) compared to the control treatment. Consequently, the combination of the two factors was the most efficient treatment for faba bean plant growth indicators studied aforementioned.
Integrated soil fertility management Operational definition and consequences for implementation and dissemination

Traditional farming systems in Sub-Saharan Africa depend primarily on mining soil nutrients. The African green revolution aims to intensify agriculture through the dissemination of integrated soil fertility management (ISFM). This paper develops a robust and operational definition of ISFM based on detailed knowledge of African farming systems and their inherent variability and of the optimal use of nutrients. The authors define ISFM as a set of soil fertility management practices that necessarily include the use of fertilizer, organic inputs and improved germplasm, combined with the knowledge on how to adapt these practices to local conditions, aimed at maximizing agronomic use efficiency of the applied nutrients and improving crop productivity. All inputs need to be managed in accordance with sound agronomic principles. The integration of ISFM practices into farming systems is illustrated with the dual-purpose grain legume–maize rotations in the savannas and fertilizer micro-dosing in the Sahel. Finally, the dissemination of ISFM practices is discussed.

Levantine standardized luxury in the late Bronze Age: Waste management at Tell Atchana (Alalakh)

The vast majority of these Late Bronze Age restrooms were excavated by Woolley during the 1930s and 1940s, and he provided short descriptions of them, as well as related general plans (including some photos) in his final excavation report. The number of well-preserved bathrooms and restrooms at Tell Atchana is extraordinary in comparison to that found at any other Middle or Late Bronze Age Levantine site. At Alalakh Levels VI-I there was a single standard for bathrooms and restrooms, which was used ubiquitously: in palaces, temples, and in upscale private houses. During the 2003 season, the Oriental Institute Expedition excavated a plastered room (03-2092) that resembles in many ways the restrooms excavated by Woolley. The plastered floor (03-2109) of Room 03-2092 is mostly preserved in the southwestern part of the room, but there are indications that it covered the entire room.Keywords: Alalakh; Late Bronze Age; Levantine site; Oriental Institute Expedition; plastered floor; Tell Atchana; Woolley
AOS-RISC-V: Towards Always-On Heap Memory Safety

Despite its notoriety for a long time, achieving robust yet practical memory safety remains challenging. In a plethora of memory-safety proposals, we observe that many recent proposals adopted the idea of pointer tagging, which places a pointer tag in the unused upper bits of a pointer and utilizes the pointer tag for a security purpose. With their promising results, such methods give us hope for the end of the eternal war in memory safety. In this paper, we revisit one of the first pointer-tagging methods and examine its feasibility as a runtime solution. To this end, we prototype AOS-RISC-V, a RISC-V-based full-system framework that ensures heap memory safety. For realistic evaluation, we base our design on the open-source RISC-V BOOM core, one of the most sophisticated RISC-V out-of-order processors. We then implement lightweight hardware extensions for new ISA support and bounds-checking mechanisms. To enable AOS-RISC-V in a real system, we further design new compiler passes in the LLVM compiler framework and add operating system support in the Linux kernel, both of which are compatible with RISC-V. All together, we demonstrate our prototype running under Linux on FPGAs and conduct a full-system-level evaluation. Our evaluation results report a 20% average slowdown for the selected SPEC 2006 workloads.
