Investigating the Synergistic Effects of Using Nitrogen and Sulfur Fertilizers on the Growth of Safflower (<i>Carthamus tinctorius</i> L.)

Nutrient imbalance is one of the prevalent problems in the semi-arid region. The study aimed to investigate the effects of sole and simultaneous application of nitrogen and sulfur on safflower yield in a semi-arid region. A field trial was designed to explore the combined use of sulfur (S0: control, S1 and S2: 25 and 50 kg ha-1 S via sulfur phosphate composites, S3 and S4=: 25 and 50 kg ha-1 of S via elemental sulfur, S5 and S6: 25 and 50 kg ha-1 of S via zinc sulfate) and nitrogen (0, 40 and 80 kg ha-1) on the growth and seed production of safflower (Carthamus tinctorius L.) in a west of Iran with mesic active calcixerepts soil that had medium to low fertility. The utilization of large amounts of nitrogen greatly increased the height of the first pod from the ground surface (P ≤ 0.05), and the highest amount was recorded in S 6+ N80 conditions (65%). Leaf chlorophyll content was significantly affected by nitrogen consumption (P ≤ 0.01) and the highest chlorophyll was recorded in S4, S5, and S6 treatments having high levels of nitrogen. A similar trend was observed for the canopy width and the application of nitrogen, zinc sulfate, and elemental sulfur could increase this component by 33%. The highest number of heads was achieved with the use of S5 + N80 and S2 + N80, which was 15% more compared to the control. The application S2 + N80 increased seed number in capitulum by 25% over the control. The application of S along with high levels of nitrogen improved the seed yield by 45% (1334 ± 78.35 kg ha-1). However, only the application of sulfur could improve the harvest index (P ≤ 0.05). The results indicated that applying moderate to high amounts of zinc sulfate and elemental sulfur, in combination with N80, enhanced safflower growth characteristics and improved seed yield components, likely due to synergistic interactions between the elements. Altogether the use of zinc sulfate or elemental sulfur as a logical and effective management solution can increase the efficiency of nitrogen fertilizer and improve nutritional balance.

Detecting Distributed Denial-of-Service (DDoS) Attacks Through the Log Consolidation Processing (LCP) Framework

One major problem commonly faced by organizations is a network attack especially if the network is vulnerable due to poor security policies. Network security is vital in protecting not only the infrastructure but most importantly, the data that moves around the network and is stored within the organization. Ensuring a secure network requires a complex combination of hardware including both network and security devices, specialized applications such as web filtering and log management, and a group of well-trained network administrators and highly skilled analysts. This paper aims to present an alternative to the current log management solution. A hindrance to the current log management solution is the difficulty in amalgamating and correlating a vast number of logs with different formats and variables. This paper uses a novel framework called Log Consolidation Processing (LCP) based on the System Information Event Management (SIEM) technology, to monitor the behavior and the fitness of a network. LCP provides a flexible and complete solution to collect, correlate, and analyze logs from multiple devices as well as applications. An experiment testing the effectiveness of LCP in detecting DDoS attacks in a campus network environment was conducted, demonstrating a highly successful rate of detection. Besides threat detection and avoidance through log monitoring and analysis, other benefits of implementing the LCP framework are also included. This paper concludes by mentioning suggested enhancements for the LCP framework.

A Low-Impact Development-Based Modeling Framework for Flood Mitigation in a Coastal Community

Urbanization is known to increase the volume of stormwater runoff and peak flow rates, which leads to changes in the natural flow regime and increases the likelihood of flooding. Low-impact development (LID) practices seek to reduce runoff volume and peak flow and are generally considered to be a more sustainable solution for urban stormwater management. In this study, we present a systematic approach to address nuisance flooding issues in small cities and communities. As an application, the effectiveness of two LID practices, rain barrels and permeable pavements, were explored in mitigating the urban flooding problem of a highly urbanized small coastal watershed in Alabama, USA. The EPA Stormwater Management Model (SWMM) was first calibrated for water depth using data collected at multiple sites within the watershed during the 2014–2015 period. The calibrated model was then used to first identify the areas prone to flooding using design storms with 1, 2, 5-, 10-, 50-, and 100-year return periods. Floodplain maps were generated for those design storms with HEC-RAS. Next, LID options upstream of those flood-prone areas were assessed to potentially minimize the flooding risks. The results indicate that LID controls can have considerable benefits for stormwater management by reducing runoff volume (1–24%), peak flow rates (18–25%), and water depth (5–15%), potentially returning watersheds to their natural flow regimes, thereby minimizing the flooding risk in urbanized areas. However, the effectiveness of LIDs, especially for the runoff volume, quickly diminishes as the return periods of the storms increase. Rain barrels were identified as the most economical and effective LID within the drainage system.

Developing a multifunctional chitosan composite sponge for managing traumatic injuries

Developing porous hemostatic sponges that are both biosafe and multifunctional remains a complex challenge. Conventional hemostatic techniques often fall short in managing bleeding effectively, leading to severe critical cases such as suboptimal hemostasis, increased infection risk, and complications arising from profuse bleeding. To address these deficits, our study introduces a novel multifunctional nanocomposite sponge that synergistically incorporates chitosan (CS), cellulose (Cel), graphene oxide (GO), and silver (Ag) nanoparticles. The resulting CS/Cel/GO/Ag developed demonstrates a swelling rate exceeding 3000 %, an absorption rate of over 2100 %, and the lowest stress surpassing 20 kPa at an initial 80 % strain. In vitro analyses reveal that the CS/Cel/GO/Ag sponge has excellent cytocompatibility, non-hemolytic nature, and competence in blood cell adherence and bacterial inhibition. In vivo evaluations further demonstrate that compared to conventional hemostatic methods, the sponge substantially enhances hemostatic efficacy, as evidenced by the marked reductions in clotting times and diminished blood loss compared to conventional hemostatic methods. Specifically, the test results of the CS/Cel/GO/Ag sponge across three different models are as follows: for the rat tail amputation model, the clotting time was 99 s, while blood loss was 222 mg; for the rat liver injury model, the clotting time was 129 s. while blood loss was 812 mg; for the rat femoral artery laceration model, the clotting time was 96 s, while blood loss was 758 mg. The compelling attributes of the CS/Cel/GO/Ag sponges position them as a promising solution for the acute management of bleeding. Their excellent performance indicates they have potential role to play in trauma care.

Supply Chain Sustainability in Outer Space: Lessons to Be Learnt from Remote Sites on Earth

Space exploration, with its enormous distances and extreme environments, is a challenge to technology, human habitation, sustainability, and supply chains. On the flip-side, however, it can provide a new vantage point on how to improve human life and planetary prosperity. This objective requires the development of economic and sustainable supply chains and a governance framework to guarantee fundamental human needs and well-being under the limitations of distant and inhospitable environments. This review describes learnings for human habitation in space from remote communities on Earth that have developed and survived over generations. These include a long history of human survival strategies on Tristan da Cunha, Pitcairn Islands, Nauru, and Easter Island. Their supply chain management solutions and their problems can guide the implementation of logistics systems for the efficient use of resources in space, to satisfy vital needs of human survival but also to ensure social and governance in space, e.g., build-up of thriving communities, mobility, and industrial activities. This review demonstrates that there are significant gaps in recent space supply chain studies with respect to the space environment, social and governance. Analysis of established practices and concepts from remote regions on Earth can readily respond to these deficiencies and thus supplement space exploration. This review recommends extending the assessment of supply-chain assets from the near future to long-term strategic. This implies going far beyond current space supply chain reports to include aspects of social responsibility and governance, such as sustainable health systems, product quality management, and local decision-making.

Assessing the nutrient removal performance from rice-crayfish paddy fields by an ecological ditch-wetland system

Agricultural drainage from catchments significantly impacts aquatic ecosystems due to high nitrogen and phosphorus concentrations in runoff. While original ecological ditches and wetlands have demonstrated effectiveness in nutrient load removal, the overall impact of an ecological ditch-wetland system (EDWS) on agricultural nutrient removal has received limited attention. This study conducted a field experiment to investigate the physicochemical conditions and nutrient removal efficiency of an EDWS for purifying nutrient discharge from rice-crayfish paddy fields. Variations in water temperature (WT), dissolved oxygen (DO), pH, and total suspended solids (TSS) within the EDWS were assessed. Nutrient concentrations—including total nitrogen (TN), ammonium nitrogen (NH4-N), nitrate nitrogen (NO3-N), total phosphorus (TP), and soluble reactive phosphorus (SRP)—were monitored from the tillering to the ripening stage of the rice growth cycle. The evaluation of nutrient removal efficiencies in the EDWS revealed that ecological ditches exhibited higher removal efficiencies compared to wetlands. The average total removal efficiencies for TN, NH4-N, NO3-N, TP, and SRP were 37.50 %, 39.38 %, 38.62 %, 37.94 %, and 39.51 %, respectively, with peak removal efficiencies observed at specific growth stages of the rice crop. Furthermore, the study explored the influence of hydraulic retention time on nutrient removal efficiency in the EDWS, indicating higher nutrient discharge removal efficiencies under low water discharge rates. Linear regression analysis identified water discharge, influent nutrient loads, and TSS as significant factors affecting nutrient removal efficiency in the EDWS. This study provides valuable insights into the effectiveness of EDWS in purifying nutrient discharge from rice-crayfish paddy fields, highlighting their potential as sustainable solutions for nutrient management in agricultural landscapes.
