Drivers of land use land cover change and livelihood coping strategies in Sheka biosphere reserve; a case of Shato forest, Southwest Ethiopia

It is evident that the means of subsistence of the community have a significant impact on the management of natural resources. This study examined the socio-economic drivers of LULCC and assessed the impacts of such changes on rural livelihoods in Shato forest, southwest Ethiopia. To map the land use and land cover, supervised classifications were used. The data were collected from 358 household heads through semi-structured questionnaires. A logistic regression model was employed to investigate the dependence of rural households on forest resources. LULC analysis results showed that about 308.29 ha of wetland and 3215.6 ha of natural forest were converted to other land use types during the last 30 years. The findings reveal that a household’s education level, household size, distance from the market, total land owned, skills and social network significantly affect their dependency on forest resources. Respondents gave high rankings to covariates such as erratic rainfall (1.70), market price (1.53), low crop output (1.28), and inadequate infrastructure (1.24). These covariates force rural communities of the study area into two major livelihood diversification strategies. These were crop and income diversification. The study comes to conclude that, the extensive and imprudent use of natural resources is a result of changes in livelihood strategies to cope up with the aforementioned shocks. Thus, the decreasing nature of forest resources results in covariate shocks in the study area and needs serious intervention mechanisms to tackle this trajectory of catastrophe.

ECG changes following balloon pulmonary angioplasty in patients with chronic thromboembolic pulmonary hypertension: a retrospective study

PurposeThis research evaluates the effect of balloon pulmonary angioplasty (BPA) on cardiac electrophysiological changes in patients with chronic thromboembolic pulmonary hypertension (CTEPH).MethodsInvolving a retrospective analysis of 39 CTEPH patients (average age 61 ± 11), who had at least two BPAs and paired ECGs pre- and post-surgery, we examined changes in ECG indicators of right ventricular hypertrophy and their correlation with hemodynamic results.Results BPA yielded marked improvements in cardiac function and hemodynamics. ECG parameters, specifically the Lewis criteria and Butler-Leggett score, correlated strongly with hemodynamics and were predictive of a mean pulmonary arterial pressure (mPAP) ≥ 35mmHg. Notably, QRS complex axis normalization was observed in 25 patients, with 14 fully normalizing (range − 30° to + 90°). The qR pattern in V1 vanished in 9 cases, and 75% of the patients in qR pattern in V1 group had QRS complex electrical axis completely returned to normal range. The qR V1 group had higher mPAP and pulmonary vascular resistance (PVR), and lower cardiac output and index compared to the non-qR V1 group, alongside a higher Butler-Leggett score.ConclusionsBPA enhances cardiac function and hemodynamics in CTEPH patients, with certain ECG measures such as Lewis criteria and Butler-Leggett score reflecting the severity of hemodynamic impairment. The reversal of QRS axis deviation and the disappearance of the qR pattern in lead V1 may serve as valuable indicators for assessing post-BPA satisfaction in CTEPH patients.

Impact force measurement by in-plane piezoelectricity of polyvinylidene fluoride films

This manuscript provides a new idea to solve the problems related to measurement of impact force wave especially in the situation with a strong environment noise by utilizing the polyvinylidene fluoride (PVDF) film instead of strain gauge. According to our experimental results, an extremely high ratio between output signal and noise in environment (SN ratio) is realized even the infrequently employed in-plane piezoelectricity of film is utilized. Instead of piezoelectricity in thickness direction, attachment of film on Hopkinson pressure bar based on in-plane piezoelectricity could help us to avoid the influence from separation of Hopkinson pressure bar on measurement result. We could conclude that a more precise measurement could be realized by a short film rather than long one even though the short film shows a relative lower output signal. However, the output signal could be amplified by increasing its width. Besides, comparing with the use of strain gauge, broader bandwidth of film measurement is discovered. In the situation where the duration of impact force wave is extremely short, high accuracy measurement should be realized by PVDF film rather than strain gauge.

SISTEME VERTICALE HIDROPONICE: INTENSIFICAREA REZISTENȚEI LA CLIMĂ, EFICIENȚEI APEI ȘI AGRICULTURII URBANE

This paper explores hydroponic vertical systems as a sustainable solution to modern agricultural challenges, particularly those posed by climate change. Hydroponics, a method of growing plants without soil using nutrient-rich water solutions, offers significant advantages over traditional farming. Vertical systems maximize space efficiency by growing plants in stacked layers, making them ideal for urban environments with limited space. These systems provide a controlled environment that mitigates the impacts of extreme weather, ensuring consistent crop production. The paper reviews various hydroponic techniques, including deep water culture, nutrient film technique, flood and drain, and drip irrigation. It highlights the efficiency of water use in hydroponics, crucial for areas facing water scarcity. Advanced technologies, such as sensors, automated nutrient delivery, and LED lighting, are employed to optimize growing conditions, enhance resource use efficiency, and improve crop yields. LED lights, in particular, offer energy efficiency, customizable spectra, and low heat output. Mathematical models are used to maximize plant development and resource efficiency, providing a framework for understanding plant-environment interactions. Despite high initial setup costs and the need for technical expertise, hydroponic systems present long-term economic and environmental benefits. This paper underscores hydroponic vertical systems' potential to revolutionize urban agriculture, ensuring food security and sustainability amidst climate change challenges.

An Analysis of the Patterns of Economic Growth in the US

ABSTRACT This article seeks to investigate which demand component led and shaped the growth patterns of the US economy between 1954 and 2020 and comprehensive sub-periods relying on a proper allocation of imports. In doing so, it aims to establish whether the external sector can make a positive contribution to growth even in a context of negative net exports. Finally, it seeks to shed light on the reasons for higher or lower output growth, drawing particular attention to the engines of growth in each historical period. This article takes a novel approach in two ways: (1) it calculates and analyzes the decomposition of the contributions to growth for the US; (2) it divides the analysis into sub-periods and engines of growth, separately analyzing movements in the components of the multiplier, the dynamics of each component’s share with respect to GDP, and their respective growth rates. The empirical results show that the very low growth rates experienced between 2008 and 2020 are mainly explained by a minimal contribution of the government sector accompanied by weak demand from the private sector, highlighting the importance of growth-oriented public policies. These negative results have been only partially compensated by improvements in the external sector.

A novel prediction method for low wind output processes under very few samples based on improved W‐DCGAN

AbstractThe threat of long‐term low wind output processes (LWOP) on the supply ability of the power system is escalating with the increasing integration of wind power. Accurate prediction of LWOP is crucial for maintaining the stable operation of the power system. However, the occurrence probability of LWOP is low and the available samples are lacking, limiting the high‐accuracy predictive modeling of LWOP. Therefore, a novel prediction method for LWOP under very few samples based on improved Wasserstein deep convolutional generative adversarial networks (W‐DCGAN) is proposed here. Firstly, a multi‐dimensional identification method is proposed to accurately identify historical LWOP. Then, an LWOP sample generation model based on improved W‐DCGAN is established. The model integrates a long short‐term memory layer into the deconvolutional layer of the generator to enhance the temporal characteristics of generated samples. Finally, three prediction algorithms are used to construct LWOP prediction models based on both generated and actual samples, respectively. The wind power operation data from a province in China is taken as an example to verify the effectiveness of the proposed method. The results show that the prediction accuracy of LWOP can be improved by 14.36%–55.85%.

Noncontact magnetically coupled piezo-electromagnetic rotary energy harvester

Aiming at the problems of high environmental vibration frequency, low output power and short life of the energy harvesters, a noncontact magnetically coupled piezo-electromagnetic rotary energy harvester is proposed in this paper. It consists of a base, a top cover, a rotating body, a cantilever beam, a permanent magnet, a coil, a hollow tube and a clamp. The novel hybrid harvester can produce both piezoelectric and electromagnetic energy at the same time, and in addition, it can efficiently generate electricity at low ambient vibration. Moreover, the piezoelectric material is protected from direct collision by noncontact magnetic coupling excitation. In order to conduct a comprehensive study on the performance of the piezoelectric-electromagnetic rotary energy harvester, we set up a rotating test platform to carry out systematic test verification, and to determine the distance between the permanent magnet and the rotating body and the number of permanent magnets on the rotating body. The test results show that when four permanent magnets are uniformly pasted on the rotating body and the rotating speed is 775 r/min, the piezoelectric and electromagnetic output power are 3.4 mW and 2.69 mW, respectively, and the total hybrid output power is 6.09 mW.

Disparities in public transport accessibility in London from 2011 to 2021

Addressing urban inequalities has become a pressing concern on both the global sustainable development agenda and for local policy. Improving public transport services is seen as an important area where local governments can exert influence and potentially help reduce inequalities. Existing measures of accessibility used to inform decision-making for public transport infrastructure in London show spatial disparities, yet there is a gap in understanding how these disparities vary across demographic groups and how they evolve over time—whether they are improving or worsening. In this study, we investigate the distribution of public transport accessibility based on ethnicity and income deprivation in London over the past decade. We used data from the Census 2011 and 2021 for area-level ethnicity characteristics, English Indices of Deprivation for income deprivation in 2011 and 2019, and public transport accessibility metrics from Transport for London for 2010 and 2023, all at the small area level using lower super output areas (LSOAs) in Greater London. We found that, on average, public transport accessibility in London has increased over the past decade, with 78% of LSOAs experiencing improvements. Public transport accessibility in London showed an unequal distribution in cross-sectional analyses. Lower income neighbourhoods had poorer accessibility to public transportation in 2011 and 2023 after controlling for car-ownership and population density. These disparities were particularly pronounced for underground accessibility. Temporal analyses revealed that existing inequalities with respect to income deprivation and ethnicity are generally not improving. While wealthier groups benefited most from London Underground service improvements; lower income groups benefited more from bus service improvements. We also found that car ownership levels declined in areas with substantial increases to public transport accessibility and major housing developments, but not in those with moderate improvements.

Continuous fabrication of flexible, high-performance PEDOT: PSS thermoelectric fiber without post-processing

Organic thermoelectric fibers (OTEFs) are popular in wearable self-powered technology due to easy weaving and power generation. However, limitations include poor spinning capability, weak mechanical strength, low output power, and dangerous post-treatment. Here, we report the rapid preparation of flexible, high-performance OTEFs without post-treatment through introducing ionic liquid (IL) of 1-ethyl-3-methylimidazolium bis (trifluoromethylsulfonyl) imide (EMIM: TFSI) into the Poly (3,4-ethylene dioxythiophene): Poly (styrene sulfonate) (PEDOT: PSS) to enhance thermoelectric properties, and mechanical strength, with just 1 wt% of IL enabling continuous fabrication of the PEDOT: PSS fiber. The resulting fiber exhibits remarkable electrical, and thermoelectric performance of ∼2267.7 S cm−1, and ∼85 μW m−1 K−2, respectively. It also demonstrates excellent strength (∼289.72 MPa), with a resistance change of less than 8 % after 10,000 bending cycles. The fabricated five-legs devices achieve an impressive output power and output power density of ∼7.84 nW and ∼4.32 μW cm−2 at 49 K, and the fabric textile generates a significant voltage of ∼47.8 mV using human body heat. This work proposes a new design strategy for high-performance organic thermoelectric fibers without additional post-processing, and the ultra-high output power and flexibility exhibit excellent combined application potential in both organic and inorganic TE fields.

Cerebral Protection With Deep Hypothermic Circulatory Arrest During Total Arch Replacement Using the Arch-First Technique for Acute Aortic Dissection.

Stroke remains a serious complication after total arch replacement (TAR). To prevent this, deep hypothermia is commonly employed during TAR. We evaluated the effectiveness of cerebral protection using deep hypothermic circulatory arrest (DHCA) during TAR with the arch-first technique, focusing particularly on patients with acute aortic dissection (AAD). This retrospective study included 109 consecutive patients with AAD who underwent emergency TAR using the arch-first technique under DHCA, and 147 patients with non-ruptured aneurysm who underwent scheduled TAR using the same technique between October 2009 and July 2022. We reviewed these patients for major adverse events, including stroke and 30-day mortality after surgery. We also analyzed the impact of clinical variables and anatomical features on the occurrence of newly developed stroke after TAR in patients with AAD. A newly developed stroke after TAR occurred in 11 (10.1%) patients with AAD. These were attributed to embolism in eight patients, malperfusion in two patients (including one who had been comatose), and low output syndrome in one patient. A stroke occurred in 3 (2.0%) patients with aneurysm, all due to embolism (P = 0.005). The DHCA time was 37 ± 7 minutes for patients with AAD and 36 ± 6 minutes for patients with aneurysm (P = 0.122). The 30-day mortality rate was 10 (9.2%) for patients with AAD and 2 (1.4%) for patients with aneurysm (P = 0.003). In our multivariable analysis, arch vessel dissection with a patent false lumen (double-barreled dissection) was the only significant predictor of newly developed stroke after TAR for AAD (odds ratio, 33.02; P < 0.001). Patients with aneurysm undergoing TAR using the arch-first technique under DHCA experienced significantly better outcomes, in terms of newly developed stroke and 30-day mortality, than those with AAD. Cerebral protection with DHCA during TAR using the arch-first technique continues to be a viable option. Newly developed stroke in patients undergoing TAR for AAD appears to be associated with air emboli deriving from the residual dissection with a patent false lumen in the repaired arch vessels.

Titanium-Cerium Redox Flow Batteries for Grid-Scale Electrical Energy Storage

The development of redox flow batteries (RFBs) has gained increased attention due to the need of mitigating emission pollution from fossil fuels by developing renewable energy storage system. Among all the different types of RFBs, all vanadium one (VRFBs) are the most prevalent type because crossover contamination is avoided by using only one metal element. However, VRFBs still suffer from limitations such as low output voltage, low efficiency, and high material cost. Titanium (Ti) and cerium (Ce), on the contrary, are available in abundance and have lower cost. Moreover, the standard potential of Ti-Ce combination is much higher than that of VRFBs (1.61 vs. 1.23 V). Herein, we have studied and compared the performance of Ti-Ce RFBs with sulfuric acid (SA) and methanesulfonic acid (MSA) serving as the supporting electrolyte. We applied an asymmetric electrode configuration, i.e., carbon felt for Ti side and carbon paper for Ce side, to further promote the batteries performance. Cyclic voltammetry (CV) and linear sweep voltammetry (LSV) were used to analyze the mass transport and reaction kinetics of the Ti-Ce system. Electrochemical impedance spectroscopy (EIS) was used to analyze the contribution of different types of polarization. Ti-Ce RFBs demonstrated an energy efficiency around 80 % at 100 mA/cm2, and excellent capacity retention.

Carbon‐Based Textile‐Structured Triboelectric Nanogenerators for Smart Wearables

Recent advances in wearable electronics have been propelled by the rapid growth of microelectronics and Internet of Things. The proliferation of electronic devices and sensors relies heavily on power sources, predominantly batteries, with significant implications for the environment. To address this concern and to reduce carbon emissions, there is a growing emphasis on renewable energy harvesting technologies, among which textile‐based triboelectric nanogenerators (T‐TENGs) stand out as an innovative and sustainable solution due to having the interesting characteristics like large contact area, lightweight design, flexibility, comfort, scalability, and breathability. T‐TENGs can harness mechanical energy from human movement and convert it into electric energy. However, one of the challenges is low electric power output, which can be addressed by meticulous selection of material pairs with significant differences in work function and optimizing contact areas. The incorporation of carbon‐based nanomaterials, such as carbon nanotubes and graphene, emerges as a key strategy to enhance output. This review delineates recent progress in T‐TENGs incorporating carbonaceous nanofillers, comprehensively addressing fundamental classification, operational mode, structural design, working performance, and potential challenges that are hindering commercialization. By doing this, this review aims to stimulate future investigations into sustainable, high‐performance smart wearables integrated with T‐TENGs.

Urine Output and Development of Acute Kidney Injury in Sepsis: A Multicenter Observational Study.

Acute kidney injury (AKI) is common in sepsis and a urine output <0.5 mL/kg/h associated with increased mortality is incorporated into AKI diagnosis. We aimed to identify the urine-output threshold associated with increased AKI incidence and hypothesized that a higher urine output than a specified threshold, which differs from the predominantly used 0.5 mL/kg/h threshold, would be associated with an increased AKI incidence. This was a post-hoc analysis of a nationwide prospective observational study. This study included adult patients newly diagnosed with sepsis and requiring intensive care. Urine output on the day of sepsis diagnosis was categorized as low, moderate, or high (<0.5, 0.5-1.0, and >1.0 mL/kg/h, respectively), and we compared AKI incidence, renal replacement therapy (RRT) requirement, and 28-day survival by category. Estimated probabilities for these outcomes were also compared after adjusting for patient background and hourly fluid administration. Among 172 eligible patients, AKI occurred in 46.3%, 48.3%, and 53.1% of those with high, moderate, and low urine output, respectively. The probability of AKI was lower in patients with high urine output than in those with low output (43.6% vs 56.5%; P = .028), whereas RRT requirement was lower in patients with high and moderate urine output (11.7% and 12.8% vs 49.1%; P < .001). Patients with low urine output demonstrated significantly lower survival (87.7% vs 82.8% and 67.8%; P = .018). Cubic spline curves for AKI, RRT, and survival prediction indicated different urine-output thresholds, including <1.2 to 1.3 mL/kg/h for AKI and <0.6 to 0.8 mL/kg/h for RRT and mortality risk. Urine output >1.0 mL/kg/h on the day of sepsis diagnosis was associated with lower AKI incidence. The urine-output threshold was higher for developing AKI than for RRT requirement or mortality.

Consumer environmental awareness and green R&D subsidy policy under Cournot–Bertrand comparisons

ABSTRACT This study examines the impacts of consumer environmental awareness on green R&D subsidy policies under different market competition modes when firms adopt green strategies for emissions-reduction activities. We demonstrate that governments grant fewer subsidies to Cournot firms than Bertrand firms. Thus, Cournot firms produce lower outputs and invest less in green R&D. However, firms’ profits and social welfare are higher (lower) in Cournot than in Bertrand firms if the product substitutability is high (low). We also investigate an endogenous competition mode game and find that a Cournot (Bertrand) competition is a socially desirable equilibrium when products substitutability is relatively high (low) while consumer environmental awareness is not sufficiently high (low). These findings suggest that through appropriate green subsidies, antitrust authorities should monitor not only consumer environmental awareness but also firms’ competition mode coordination.

The effect of female breast surface area on heat-activated sweat gland density and output.

Female development includes significant morphological changes across the breast. Yet, whether differences in breast surface area (BrSA) modify sweat gland density and output remains unclear. The present study investigated the relationship between BrSA and sweat gland density and output in 22 young to middle-aged women (28 10years) of varying breast sizes (BrSA range: 147-561cm2) during a submaximal run in a warm environment (32 0.6°C; 53 1.7% relative humidity). Local sweat gland density and local sweat rate (LSR) above and below the nipple and at the bra triangle were measured. Expired gases were monitored for the estimation of evaporative requirements for heat balance (Ereq, in W/m2). Associations between BrSA and (i) sweat gland density; (ii) LSR; and (iii) sweat output per gland for the breast sites were determined via correlation and regression analyses. Our results indicated that breast sweat gland density decreased linearly as BrSA increased (r=-0.76, P<0.001), whereas sweat output per gland remained constant irrespective of BrSA (r=0.29, P=0.28). This resulted in LSR decreasing linearly as BrSA increased (r=-0.62, P=0.01). Compared to the bra triangle, the breast had a 64% lower sweat gland density (P<0.001), 83% lower LSR (P<0.001) and 53% lower output per gland (P<0.001). BrSA (R2=0.33, P=0.015) explained a greater proportion of variance in LSR than Ereq (in W/m2) (R2=0.07, P=0.538). These novel findings extend the known relationship between body morphology and sweat gland density and LSR, to the female breast. This knowledge could innovate user-centred design of sports bras by accommodating breast size-specific needs for sweat management, skin wetness perception and comfort.

Buck–Boost DC–AC converter based on coupled inductors

In this paper, a single stage buck–boost DC–AC converter based on coupled inductors is presented for renewable energy and electric vehicle applications. The proposed topology works with only three semiconductor switches, two diodes, and three coupled inductors to transfer input DC voltage to a high gain or low gain output AC voltage. A coupled inductor is used instead of normal inductors, which will reduce core and size requirements. The sinusoidal pulse width modulation strategy is used in this paper for controlling the main switch. There are many merits in the presented topology, like high gain up to five times of input voltage, compact size, less number of components, which results in reducing the overall cost, reducing switching loss, and increasing the converter efficiency. The simulation study is carried out using MATLAB/SIMULINK to simulate the operation of the proposed converter. Also, an experimental setup is built up to examine the actual operation of the proposed converter. There is a good agreement between simulation and experimental results which increases the validation and confidence of the model.

Optimization of solar energy using artificial neural network vs recurrent neural network controller with positive output super lift Luo converter

In today’s world, the need for clean energy is crucial. Historically, Renewable energy sources like hydropower, wind, and solar offer sustainable solutions. Photovoltaic (PV) systems convert sunlight into electricity using semiconductor PV cells, which have been efficient for over 30 years. PV cell efficiency depends on irradiance (solar photon intensity) and temperature. Higher irradiance increases efficiency, while higher temperatures decrease it. PV systems, despite low voltage outputs, can be optimized using DC-DC Positive Output Super Lift Luo converters to match load requirements, enhancing system efficiency. Solar irradiance varies throughout the day, affecting PV cell output. Maximum Power Point Trackers (MPPTs) adjust the system's operating point to maintain peak efficiency. This study focuses on designing AI controllers to manage MPPT. We compare the performance of Artificial Neural Networks (ANN) and Recurrent Neural Networks (RNN) using three datasets. The goal is to identify the most efficient AI controller for optimizing solar energy systems.

Single-walled Carbon Nanotubes Wrapped with Charged Polysaccharides Enhance Extracellular Electron Transfer.

Microbial electrochemical systems (MESs) rely on the microbes' ability to transfer charges from their anaerobic respiratory processes to electrodes through extracellular electron transfer (EET). To increase the generally low output signal in devices, advanced bioelectrical interfaces tend to augment this problem by attaching conducting nanoparticles, such as positively charged multiwalled carbon nanotubes (CNTs), to the base carbon electrode to electrostatically attract the negatively charged bacterial cell membrane. On the other hand, some reports point to the importance of the magnitude of the surface charge of functionalized single-walled CNTs (SWCNTs) as well as the size of functional groups for interaction with the cell membrane, rather than their polarity. To shed light on these phenomena, in this study, we prepared and characterized well-solubilized aqueous dispersions of SWCNTs functionalized by either positively or negatively charged cellulose-derivative polymers, as well as with positively charged or neutral small molecular surfactants, and tested the electrochemical performance of Shewanella oneidensis MR-1 in MESs in the presence of these functionalized SWCNTs. By simple injection into the MESs, the positively charged polymeric SWCNTs attached to the base carbon felt (CF) electrode, and as fluorescence microscopy revealed, allowed bacteria to attach to these structures. As a result, EET currents continuously increased over several days of monitoring, without bacterial growth in the electrolyte. Negatively charged polymeric SWCNTs also resulted in continuously increasing EET currents and a large number of bacteria on CF, although SWCNTs did not attach to CF. In contrast, SWCNTs functionalized by small-sized surfactants led to a decrease in both currents and the amount of bacteria in the solution, presumably due to the detachment of surfactants from SWCNTs and their detrimental interaction with cells. We expect our results will help researchers in designing materials for smart bioelectrical interfaces for low-scale microbial energy harvesting, sensing, and energy conversion applications.

Power factor preregulation in power supplies using modified single stage non-isolated interleaved Sepic converter with minimal part count

This paper pontificates on design and realization of low-cost single phase single stage modified interleaved Sepic (MILS) converter for power supplies. On contrary to the classical Sepic power converters, the introduced active power factor correction (APFC) converter involves simple idea of paralleling that enables low input and output ripples with minimal device count. The interleaving conceptualization also lessens current stresses and static losses. Also, this modified power processing converter reveals natural power factor correction (PFC) and zero current switching (ZCS) features by discontinuous conduction mode (DCM) operation. Furthermore, the practical corroboration of the proposed converter is built and tested for 250 W hardware model to affirm benefits with 92 % efficiency and their relevant outcomes are reported in this scope. Finally, the power quality (PQ) attributes like, input power factor (PF), total harmonic distortion (THD) over input current under stable and transient cases are disclosed to prove bettered PQ limits at the AC mains as prescribed by various IEEE-519 and IEC 61,000–3-2 standards.
