Quality evaluation of tithonia (Tithonia diversifolia) with fermentation using Lactobacillus plantarum and Aspergillus ficuum at different incubation times

Abstract. Pazla R, Jamarun N, Zain M, Yanti G, Chandra RH. 2021. Quality evaluation of tithonia (Tithonia diversifolia) with fermentation using Lactobacillus plantarum and Aspergillus ficuum at different incubation times. Biodiversitas 22: 3936-3942. This research aimed to evaluate the nutritional quality of tithonia (Tithonia diversifolia) fermented using Lactobacillus plantarum and Aspergillus ficuum with different incubation times on nutritional content, digestibility, phytase enzyme activity, and characteristics of rumen fluid. The research used an experimental method with a factorial completely randomized design to evaluate the nutritional content and phytase enzyme activity after fermentation (stage 1). A randomized block design was used to evaluate in vitro digestibility and rumen fluid characteristics (stage 2). For factorial completely randomized design, factor A is the type of microbe (L. plantarum and A. ficuum), then factor B is the incubation time (3,5,7 days). Parameters observed were the nutritional content of dry matter (DM), organic matter (OM), crude protein (CP), crude fiber (CF), and phytase enzyme activity. For the Randomized Block Design, the research treatments were A = A. ficuum + 5 days of incubation, B = A. ficuum + 7 days of incubation, C = L. plantarum + 3 days of incubation, D = L. plantarum + 5 days of incubation. Parameters measured were the digestibility of dry matter(DMD), organic matter (OMD), crude protein (CPD), crude fiber (CFD), rumen pH, VFA production, and NH3 rumen fluid. The results showed that there was an interaction between the type of microbe and incubation time. The treatment had a significantly different effect (P<0.05) on the content of OM, CP, CF and phytase enzyme activity, but no interaction with the content of DM treatment. In the digestibility, the results showed that the effect was not significantly different (P>0.05) on DMD, OMD, CPD but had a significant effect (P<0.05) on CFD. The treatments also had no significant effect (P>0.05) on VFA but were significantly different (P<0.05) on NH3. From this study, it can be concluded that fermented tithonia using A. ficuum with an incubation period of 7 days could improve the quality of tithonia. It can be seen from the content of CP (31.02%), CF (16.52%), phytase enzyme activity (37.36 U/ml), DMD (66.86%), OMD (67.36%), CFD (81.01%), CPD (70.37%), VFA production 135 mM and NH3 concentration 14.31 mg/100 ml, and pH value 6.72 which is suitable for rumen microbial growth.
Joint Subcarrier Assignment and Power Allocation for OFDMA Full Duplex Distributed Antenna Systems

In this paper, we investigate the resource allocation scheme for orthogonal frequency division multiple access (OFDMA) full-duplex (FD) distributed antenna systems (DASs), in which both remote access units (RAUs) and users having the full-duplex capability. We aim to maximize the system spectral efficiency through jointly optimizing subcarrier assignment and power allocation, where users’ uplink/downlink quality of service requirements, per-user uplink/downlink transmit power constraints, and subcarrier reuse are considered. The user-centric virtual cell approach is adopted to reduce the computational and signaling overhead. Based on the successive convex approximation method and penalty factor, we propose an efficient overall optimization algorithm to tackle the non-convex optimization problem. Simulation results show that the proposed algorithm can achieve performance close to the exhaustive search algorithm, comparable to the hierarchical decomposition algorithm using the optimal subcarrier allocation scheme, and better than other benchmark algorithms. In addition, the proposed algorithm can guarantee fairness among users at a low cost of system spectral efficiency.
Design and Experimental Evaluation of Transfer-Molded 650 V Super-Junction mosfet Power Module for Industrial Applications

This article presents a new transfer-molded design of a four-pack 650 V super-junction mosfet power module. This power module is designed for industrial applications, including solar energy converters and on-board chargers. In these applications, it is critical to reduce the stray inductance, package on-resistance, thermal resistance, volume, and cost of the power modules. These challenges are addressed by optimizing the module design, fabrication process, and selection of components and packaging materials. Eight super-junction mosfets, lead frames, and an SMD thermistor are soldered onto a direct bonded copper substrate, followed by a wire bonding and transfer molding process. The fabricated module exhibits low stray inductance, package on-resistance (∼16.3 mΩ), thermal resistance (∼0.26 K/W), and volume (∼43% reduction in comparison with a commercial counterpart). Moreover, the module reliability is successfully demonstrated by electrical isolation (ac voltage of 2,500 V), thermal cycling (–40 to 85°C), and power cycling (up to 100,000 cycles) tests, satisfying international standards.
Effects of Moringa oleifera and Brosimum alicastrum partial feed substitution in intramuscular fat and adipose tissues and on the expression of lipogenic genes of Mexican hairless pigs

The present study evaluated the effects of the inclusion of ground Moringa oleifera and Brosimum alicastrum leaf meal in the diet of Mexican hairless pigs (MHP) on the amount of intramuscular fat, subcutaneous fat, leg muscle (Biceps femoris) fat, loin muscle (Longissimus dorsi) fat, leg and back fat, and the expression of lipid metabolism genes. Hairless pigs are reared in the Mexican tropics and are characterised by their body and intramuscular fat accumulation. Eighteen male pigs fed for 82 d were randomly allotted to three experimental isoenergetic and isoproteic diets, where M. oleifera or B. alicastrum (six pigs per diet) replaced wheat bran. The diets used were a control diet, a diet with 10% M. oleifera leaf meal, and a diet with 10% ground B. alicastrum leaf meal. The M. oleifera diet decreased (P<0.05) the fat ratio in the Longissimus dorsi muscles, back fat, rib fat, total carcass fat, and the carcass fat: meat ratio. The B. alicastrum diet only decreased fat in the Biceps femoris muscle, back fat, and rib fat. Moringa oleifera and B. alicastrum diets also promoted the overexpression of mRNA from the stearoyl-CoA desaturase (SCD), fatty acid synthase (FASN), acetyl-CoA carboxylase alpha (ACACA), sterol regulatory element-binding protein 1 (SREBP1) and acyl carrier protein (ACP) lipogenic genes in the Biceps femoris muscle and leg fat (P<0.001). In addition, lower ACACA and SREBP1 mRNA expression in the Longissimus dorsi muscle and back fat (P<0.001) were related to the lower amount of fat in pigs fed M. oleifera and B. alicastrum. The inclusion of Moringa oleifera and Brosimum alicastrum meals 10% in the diet of the pig MHP reduces fat, this is an important finding because fat is abundant in this type of pig.
Governance and Regulation of Ride-hailing Services in Emerging Markets: Challenges, Experiences and Implications

This paper seeks to shed some light on the different considerations for regulation and governance of ride-hailing platforms in emerging markets, highlighting their positive and negative externalities. Building on an extensive review of the literature and secondary sources, we outline Ride-hailing's identified and potential effects on users (providers and consumers), incumbents, and society. Based on the welfare impacts structure, we identify the significant challenges that regulators face in understanding, monitoring, evaluating, and regulating this type of transportation innovation. Finally, the paper proposes a framework for approaching such mobility innovations from governance and regulation perspectives. In a context of exponential growth in research and innovation in urban mobility in general and Ride-hailing, a rigorous review of the literature and a critical framework for understanding governance and regulation in such services in rapidly changing contexts is a timely contribution.
Cloud-Free Sea-Surface-Temperature Image Reconstruction From Anomaly Inpainting Network

Sea-surface temperature (SST) images obtained by satellites contain noise and missing SSTs due to cloud covers. We propose a method for reconstructing denoised cloud-free SST images via deep-learning-based image inpainting. For denoizing, we use data-assimilation images to train a reconstruction network by considering the physical correctness of SSTs. For reconstruction stability, we introduce anomaly inpainting network, which does not directly complete missing SSTs but estimates the difference between the unobserved SSTs and the average SSTs. SSTs do not fluctuate much over a few days; thus, we can use recent average SSTs as a rough estimation of SSTs and can assume that the SST difference will be within a specific range. We conducted experiments to evaluate our method with satellite SST images and in situ SST data. The results indicate that our method with anomaly inpainting network qualitatively and quantitatively outperformed conventional SST image inpainting methods.
The First Commercially-Scaled Study on the Influence of Long Dark and Light Photoperiod Manipulation on the Egg and Larvae Performance of Rainbow Trout (Onchorhynchus mykiss)

ABSTRACT Engin, S. , 2022. The first commercially-scaled study on the influence of long dark and light photoperiod manipulation on the egg and larvae performance of rainbow trout (Onchorhynchus mykiss). Journal of Coastal Research, 38(1), 196–203. Coconut Creek (Florida), ISSN 0749-0208. Spawning success, number of eyed-egg, and larval growth performance of rainbow trout are largely affected by a variety of biotic and abiotic factors. The photoperiod is important in initiating or suppressing breeding timing and gonadal maturation that varies by species. The aims of this study were to investigate the effect of two different commercial photoperiod manipulations on the growth of total eyed eggs, egg diameter, and larvae under specific fish farm conditions. The control group (outdoor broodstock ponds and natural sunlight) fish were fed using a commercial broodstock feeding protocol in September and transferred to the hatchery in February for spawning. The female and male broodstocks were exposed to direct photoperiod (Experimental Group 1: M1), and for the adapted photoperiod (transition from light to dark periodically, Experimental Group 2: M2) they were exposed to 18 hours of light and 6 hours of darkness between January and April. The M1 group were exposed to a direct application of 18 hours of dark and 6 hours of light, and a transition from light to dark for 18 hours and from dark to light for 6 hours was applied to M1 that was completed over 48 days with a daily decrease of 17 minutes. The results of the trials showed that larval growth was higher in the groups treated with long light and long dark, 18 hours light/6 hours dark and 18 hours dark/6 hours light compared to the control group, and statistically significant difference between larval survival rate and daily weight gain was observed between all three groups (p < 0.05). As a result, at the end of the photoperiod, applications and larvae breeding performed for one year under commercial operating conditions were compared, and larvae with higher survival and growth rates were obtained with long light and long dark application.
Group work on the edge. Embracing the messiness of group facilitation with marginalised peoples

This poster explores concepts of discomfort and messiness in terms of what they mean for participants, facilitators and auspicing agencies of group work. Where 'tidy' theory does not prepare social workers for the 'messiness' of group work practice, this poster proposes a model for working with group processes that captures both linear and organic understandings. Further, the poster explores opportunities for maximising the benefits of group work in the context of unpredictable group processes as well as participants’ and facilitators’ potentially chaotic lives.
Organic Functionalization on the Non-Ideal Si(001) Surface – Structure, Bonding and Reactivity

In this density functional theory study, the influence of the dimer vacancy on the reactivity of the Si(001) surface is investigated. To this end, electronic and structural properties of the defect are analyzed. Band structure calculations reveal a higher-lying valence band which would suggest increased reactivity. However, the opposite is found when organic molecules for interface formation (acetylene, ethylene and cyclooctyne) are adsorbed at the defect. Significant reaction barriers have to be overcome in order to form bonds with defect atoms, while adsorption on the pristine surface is mostly direct. This suggests the presence of a, rather weak, Si-Si bond across the defect which must be dissociated before organic adsorbates can react. A rich adsorption and reaction network is found in addition to the structures known from the pristine surface. All three investigated adsorbates show different bonding characteristics. For acetylene and ethylene, the preferred thermodynamic sink is the insertion into the defect, with the latter molecule even dissociating. Bulky cyclooctyne on the other hand avoids reaction with the defect due to steric demands imposed by the small defect cavity. The DV has no effect on reactivity of neighboring dimers. A combination of defect creation and hydrogen-precoverage could be a promising approach for selective surface functionalization. We thus show the influence of a non-ideal surface on organic functionalization and interface build-up reactions for a prototypical interface.
Performance gap of two users in downlink full-duplex cooperative NOMA

A full-duplex non-orthogonal multiple access (FD- NOMA ) systems are expected to play a significant role in fifth generation ( 5G ) networks, addressing spectrum efficiency and massive connections. In this regard, the feasibility of FD communications to improve spectrum utilization is main consideration in term of outage performance. Specifically, we derive exact formulas of outage probability for FD- NOMA , over Nakagami - $m$ fading channels. Extensive analysis revealed that higher quality of channel leads to better performance. We verify expressions throughout Monte-Carlo simulations.
To draw or not to draw: Informed consent dilemma

Background : Informed consent is a worldwide standard medical practice. The purpose of this study was to determine whether surgical freehand-drawings do facilitate surgeons in the communication process. Methods : Authors carried out a questionnaire survey aimed at exploring physicians’ perceptions of the usefulness of drawings, in terms of level of understanding in consent acquisition procedures. A total of 90 anonymous questionnaires were distributed for doctors to fill in, in surgical and interventional medicine wards of the University Hospital of Turin. Results : Out of the 90 questionnaires delivered, 37.8% (n=34) were filled out. 93.8% (n=30) of the physicians interviewed consider freehand-drawings a useful tool, 90% (n=27) of the surgeons, who confirmed to routinely use drawing for informed consent acquisition purposes. 96.3% (n=26) of the physicians who draw themselves illustrative images of proposed treatments asserted to perceive a real benefit in patients’ comprehension of the information when visually provided. Many respondent surgeons stated to consider drawing an effective means of information for consent acquisition. Nonetheless, just in 7.4% of the cases, personally drawn explicative images are then added in patients’ medical records, with possible detrimental effects on a medico legal point of view. Conclusions : Graphical representation is useful for breaking down comprehension barriers resulting not only from the modality in which the information is conveyed but also from patients’ relational, social, and psychological factors, ensuring bi-directionalness of communication and prove in Italy, a Civil Law Country, the communicative effort of physicians in the best interest of the patients.
On theory of finite subsets monoid for one torsion abelian group

Ранее был доказан следующий результат: если абелева группа $\gG$ не является группой кручения, то теория моноида ее конечных подмножеств позволяет интерпретировать элементарную арифметику. В настоящей работе мы приводим пример, который показывает, что аналогичный результат можно получить и, по крайней мере, для некоторых групп кручения. Earlier it was proved the following claim. Let $\gG$ be a non-torsion abelian group and $\gG$ be the semigroup of finite subsets of $\gG$. Then elementary arithmetic can be interpreted in $\gG^*$, so the theory of $\gG^*$ is undecidable. Here we prove the same result for one torsion group, the multiplicative group of all roots of unity.
Self-Heating and Reliability-Aware “Intrinsic” Safe Operating Area of Wide Bandgap Semiconductors—An Analytical Approach

The emergence of several technology options and the ever-broadening range of applications (e.g., automotive, smart grids, solar/wind farms) for power electronic devices suggest both a need and an opportunity to develop unifying principles to guide the development of wide bandgap (WBG) semiconductors. Unfortunately, power electronic devices are typically evaluated with a variety of elementary figure of merits (FOMs), which offer inconsistent/contradictory projections regarding the relative merits of emerging technologies. Indeed, one relies on the empirical (extrinsic) safe-operating area (SOA) of a packaged device to ultimately assess the performance potential of a technology option. Unfortunately, extrinsic SOA can only be calculated a posteriori, i.e., after precise measurement of the fabricated device parameters, making it suitable only for relatively mature technologies. Based on the insights of material-device-circuit-system performance analysis of a variety of idealized WBG power electronic devices (e.g., GaN HEMT, ${\beta }$ -Ga2O3 MOSFET), in this paper, we analytically derive a comprehensive, substrate-, self-heating-, and reliability-aware “intrinsic/limiting” safe operating area (SOA) that establishes a priori, i.e., before device fabrication, the optimum and self-consistent trade-off among breakdown voltage, power consumption, operating frequency, heat dissipation, and reliability. We establish the relevance of the intrinsic-SOA by comparing its prediction with a broad range of experimental data available in the literature. In between the traditional FOMs and extrinsic SOA, the intrinsic SOA allows fundamental/intuitive re-evaluation of intrinsic technology potential for power electronic devices and identifies specific performance bottlenecks and suggests strategies to circumvent them.
La biofeedback loop et les œuvres d’art interactives : quel façonnement émotionnel de soi ?

The autopoiesis function of the biofeedback loop-based virtual reality artistic experience relies on several factors, which are contextual, technological (medium-based) and artistic. We need to describe and analyse this function in order to answer more specifically the following questions: Which artistic uses and practices are worth considering in the realm of biofeedback loop-based interactive media? What to make of the emotional shaping of the self when it is considered through the lens of those particular devices? Especially when the feedback from the other’s or the group’s body activities are sometimes forcibly integrated in the subject’s (individual) phenomenological experience.
Is sleeve lobectomy safe after induction therapy?—a systematic review and meta-analysis

Background Sleeve lobectomy (SL) is a lung-sparing procedure, which is accepted as a valid operation for centrally-located advanced tumors. These tumors often require induction treatment by chemotherapy and/or radiotherapy to downstage the disease and thus facilitate subsequent surgery. However, induction therapy may potentially increase the risk of bronchial anastomotic complications and related morbidity. This meta-analysis aims to determine the impact of induction therapy on the outcomes of pulmonary SL. Methods We compared studies of patients undergoing SL or bilobectomy for non-small cell lung cancer (NSCLC) with and without induction therapy. Outcomes of interest were in-hospital mortality, morbidity, anastomosis complication and 5-year survival. Odds ratio (OR) were computed following the Mantel-Haenszel method. Results Ten studies were included for a total of 1,204 patients. There was no statistical difference for between patients who underwent induction therapy followed by surgery and patients who underwent surgery alone in term of post-operative mortality (OR: 1.80, 95% confidence interval (CI): 0.76–4.25, P value =0.19) and morbidity (OR: 1.17, 95% CI: 0.90–1.52, P value =0.237). Anastomosis related complications rate were 5.2% and appears increased after induction therapy with a statistical difference close to the significance (OR: 1.65, 95% CI: 0.97–2.83, P value =0.06). Patients undergoing surgery alone showed better survival at 5 years (OR: 1.52, 95% CI: 1.15–2.00, P value =0.003). Conclusions SL following induction therapy can be safely performed with no increase of mortality and morbidity. However, the need for induction therapy before surgery is associated with increased anastomotic complications and poorer survival prognosis at 5 years.
COVID-19 and risk of cardiomyocyte injury: The prevailing scenario

The novel coronavirus which is also called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is responsible for COVID-19 (coronavirus disease 2019). SARS-CoV-2 is known to cause substantial pulmonary disease, including pneumonia and acute respiratory distress syndrome (ARDS), clinicians have observed many extra-pulmonary manifestations of COVID-19. SARS-CoV-2 infection is associated with a variety of pro-inflammatory mediators that may play important roles in the pathophysiology of cardiac and arrhythmic complications. Systemic inflammatory response syndrome (cytokine storm) is another putative mechanism of myocardial injury. In addition to lung damage, there may be significant cardiac involvement in patients with COVID-19, which is responsible for worsening the clinical condition of the host. The main cardiac manifestations can be oedema, pericarditis, cardiac fibrosis, myocarditis, impairment of contractile function and cardiac electrophysiology. The cardiac status of patients with ongoing SARS-CoV-2 infection of surviving patients in convalescence period should be carefully monitored.
Does Trade Pattern Enhance Institutional Quality? Comparison across Regions

Abstract We empirically investigate how trade pattern – institutionally intensive export (IIX) – affects institutional quality, a source of comparative advantage for IIX. Using panel data for147 countries from 2002 to 2016, we examine the effect of IIX on institutional quality across regions. Our estimation results of fixed effects and dynamic panel models show significant regional heterogeneity. Most noticeably, the effect is negative and significant only for East Asia robustly in all dynamic models. Our result suggests that IIX may not unambiguously improve institutional quality across the board, and the effect needs to be considered differently across regions.
