Published: January 2020

Background:

Cortical superficial siderosis (cSS) is a hemorrhagic marker of blood-brain barrier disruption detected in brain MRI. Together with cerebral microbleeds (CMB), they are recognized as a small vessel disease marker associated with cerebral amyloid angiopathy.

Objective:

This study aims to determine the prevalence and the characteristics of cSS in a memory clinic population.

Methods:

Cross-sectional retrospective analysis of 613 patients from Geneva University Hospitals memory clinic. All patients underwent standardized brain MRI and neuropsychological assessment with diagnosis confirmed by an expert. The presence of cSS was visually assessed and classified as focal (restricted to 3 sulci) or disseminated within the correspondent topography. CMB were classified according to the Microbleed Anatomical Rating Scale.

Results:

cSS was detected in 26/613 patients (4.2%), classified as disseminated in 5/26 cases (19%). Alzheimer’s disease (AD) and AD associated with a significant vascular component were the diagnoses more frequently related to cSS (18/26; 69%). Patients with cSS had an increased prevalence of both hypertension (81% versus 57%; p = 0.015) and WMH burden ( p = 0.012). The overall prevalence of cerebral microbleeds (69% versus 32%; p < 0.01), as well as their mean number (0.69±0.47 versus 0.32±0.46; p < 0.01) were both increased in patients with cSS. In the logistic regression model, the presence of 5 or more CMB (OR 11.35; 95% CI 4.68–27.55; p < 0.01) and hypertension (OR 3.31; 95% CI 1.19–9.15; p = 0.021) were significantly associated with cSS.

Conclusions:

cSS is observed in patients diagnosed with AD and AD with a vascular component, being independently associated with multiple CMB and hypertension.

Published: January 2020

Alzheimer’s disease (AD) is a common form of dementia characterized by amyloid plaque deposition, tau pathology, neuroinflammation, and neurodegeneration. Mouse models recapitulate some key features of AD. For instance, the B6. APP/PS1 model (carrying human transgenes for mutant forms of APP and PSEN1) shows plaque deposition and neuroinflammation involving both astrocytes and microglia beginning around 4–6 months of age. However, significant tau pathology and neurodegeneration are not apparent in this model even when assessed at old age. Therefore, this model is ideal for studying neuroinflammatory responses to amyloid deposition. Here, RNA sequencing of brain and retinal tissue, generalized linear modeling (GLM), functional annotation followed by validation by immunofluorescence was performed in B6. APP/PS1 mice to determine the earliest molecular changes prior to and around the onset of plaque deposition (2–6 months of age). Multiple pathways were shown to be activated in response to amyloid deposition including the JAK/STAT and NALFD pathways. Putative, cell-specific targets of STAT3, a central component of the JAK/STAT pathway, were identified that we propose provide more precise options for assessing the potential for targeting activation of the JAK/STAT pathway as a treatment for human AD. In the retina, GLM predicted activation of vascular-related pathways. However, many of the gene expression changes comparing B6 with B6. APP/PS1 retina samples occurred prior to plaque onset (2 months of age). This suggests retinal changes in B6. APP/PS1 mice may be an artefact of overexpression of mutant forms of APP and PSEN1 providing limited translatability to human AD. Therefore, caution should be taken when using this mouse model to assess the potential of using the eye as a window to the brain for AD.

Authors: Hasan Alfaisal A. , Mekheimer Khaled S. , Tantawy Bassem E.
Published: January 2020

The present work studies magnetohydrodynamic stability with streaming resistive triple superposed fluid layers. This system is influenced by an oblique magnetic field. The solution of motion equations by using the method of perturbation analysis under the boundary conditions which leads to deriving the dispersion relationship describing the behaviour of the perturbed and unperturbed system. The effect of different parameters on the stability and the instability of this system was studied. Regions of stability and instability are identified by drawning the curves to illustrate the regions of stability and instability behaviour. It is found that the magnetic field permeability coefficient, the intensity of the magnetic field values, the increase of the fluids density values and the streaming velocity have destabilizing influences on the considered system. The presence of an oblique magnetic field plays a stabilizing role and can be used to retard the destabilizing influence.

Published: January 2020

Background:

Neuropathic feet are at very high risk for infection and amputation. The slipping slipper sign (SSS) is elicited by a simple questionnaire test reported to detect the presence of severe diabetic peripheral neuropathy. This test can be administered by non-medical staff. In this study, subjects with and without the SSS were evaluated by nerve conduction studies (NCS) and ultrasound measurements of the right sural nerve diameters as well as with traditional scoring systems for peripheral and autonomic neuropathy.

Objective:

To demonstrate that the Slipping Slipper Sign can be used as an index of severe diabetic peripheral neuropathy

Method:

This was a prospective cross sectional study in which 74 patients with diabetes (38 positive and 36 negative for SSS) underwent ultrasonography and NCS of the right sural nerve by an examiner blinded to SSS status. Findings were evaluated against demography, clinical history, anthropometry as well as traditional clinical and autonomic neuropathic scores.

Results:

Patients without the SSS [median (IQR) = 10.0 years (4.0–20.3)] had a significantly shorter duration of diabetes compared with those with the SSS [median (IQR) = 15.0 years (8.5–25.0)], p = 0.028. The frequencies of retinopathy (36.8% vs 2.8%, p <  0.05) and cerebrovascular accidents (18.4% vs 13.9 %, p <  0.05) were higher among those with SSS compared with those without. Differences in nerve conduction characteristics were markedly significant. The amplitude of the sural sensory nerve action potential (SNAP) was ([median (IQR)] 0 microvolts vs 4.0 microvolts (0.0–10.8) p <  0.002) between those with and without SSS, respectively whilst none of patients with SSS had a recordable SNAP vs 78% without a SSS. Similarly, maximal thickness of the right sural nerve at the ankle 3.0 mm (2.3–3.4) vs 3.5 mm (3.0–3.9), and leg 3.4 mm (2.7–3.8) vs 3.9 mm (3.3–4.2) was reduced, p <  0.01 in patients with the SSS compared with those with a negative SSS.

Conclusion:

The SSS identifies feet with objective neurophysiological and imaging characteristics of severe neuropathy.

Authors: Pradhan Sean , Abdourazakou Yann
Published: January 2020

The utilisation of performance criteria to determine power rankings of various teams is useful for a vast number of audiences in many traditional sports, such as soccer, football, baseball, basketball, hockey, and the like. With market hyper-competition and viewership growth in the digital sector of eSports and related professional video gaming, the usage of performance evaluation in the scholarly literature is relatively scant. Thus, the current study provides a performance assessment and ranking structure in eSports. Applying a hybrid technique developed by previous research involving a series of Multi-Criteria Decision-Making (MCDM) tools, those being: Grey Relational Analysis (GRA), Simple Additive Weighting (SAW), and the Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS), this study develops power rankings for professional teams in the popular multiplayer online battle arena (MOBA) game, Defense of the Ancients ( Dota) 2. Further analyses offer a comparison of the produced ranking structure to other metrics commonly used in eSports evaluation, such as Elo and Glicko ratings. The findings of this study offer implications for players, teams, performance analysts, oddsmakers, consumers, among others. Recommendations and future directions of this research are also provided.
Володислав Федорович та Артур Ґротґер. Забуті сторінки однієї приязні
Authors: Nabytovych Ihor
Published: January 2020

The article explores the history of the relationship of Volodyslav Fedorovych and Artur Grottger, an almost forgotten page of Ukrainian-Polish intercultural dialogue of the last quarter of the nineteen century. Their friendship undoubtedly had an influence on both of their lives, and it remains an important demonstration of Ukrainian-Polish intercultural and interpersonal dialogue on the border of the two cultures of the two nations. The first of the two aforementioned men was a famous Ukrainian philanthropist, the third head of Prosvita society, a member of the Polish circle in the lower house of the Viennese Parliament. Artur Grottger died at the age of thirty; however, he became a symbol of Polish Romanticism and a champion of the Polish rebellion in January 1863. Volodyslav Fedorovych spent two years in the capital of the Habsburg Monarchy, studying in a privileged educational institution for children of noble families – Collegium Theresianum. At the same time, Volodyslav attended lectures at the University of Vienna. Vienna, one of the cultural capitals of Europe, awakened his interest in paintings and art in general. In Vienna, he met the famous Polish painter Artur Grottger, who was to introduce him later to the Ukrainian painter Kornylo Ustyanovych. Later on, Ustyanovych will become a cult figure in Galicia. The article recounts a story of his cousin Alexandra. Volodyslav was in love with her. She died very young, but Grottger managed to draw a portrait of her.
Барокові проповіді Іоаникія Галятовського
Authors: Savenko Oksana
Published: January 2020

The article deals with some of the sermons of a Ukrainian writer, preacher, and cultural figure, Ioаnikii Galytovsky, as characteristic Baroque works. The sermon belongs to traditional genres of ancient Ukrainian literature with a set of predominantly medieval style topoi and stereotypes. However, in Galytovsky’s creative practice, the transformation of the genre under the influence of Baroque is noticeable. Belonging to this style has provided not only a change of narrative strategy but above all of stylistic means. Galytovsky creates distinctive allegories, symbols, comparisons, and antitheses which characterise his Baroque style. He resorted to characteristic Baroque amplifications and emblematic images. The writer was able to revive the old form of traditional sermon with the Baroque stylistic technique, as a result of which he managed to dramatise the gospel plots, thus being able to exert the expected impact on recipients with the help of a suggestion.
Істина і неконсеквентність: парадокс Лєшка Колаковського
Authors: Bondarevska Iryna
Published: January 2020

In the philosophical works of Kolakowski, the concept of inconsistency is a guideline that moves the subject closer to truth. Truth disappears when consistency prevails, that is a logic, a method, a tradition of thinking. And there is no need to reject the sequence in general, as there is no need to follow it. But there is a conflict between Kolakowski as the Thinker and Kolakowski as the Human Being. The first one tries to find the best way to describe the world with concepts, the second one wants to gain a comfortable existence in the world. The first needs doubt, the second wants to feel certainty. The philosopher as the Human Being wants to have a firm belief in those things the Thinker can only be hopeful of. The purpose of the article is to show how the Human Being and the Thinker compete in Kolakowski’s works, as their understanding of truth and the ways to it are different. Kolakowski’s paradox is that the inconsistency of the mind should advance us towards the truth, but it reinforces doubts whether truth is possible in general. If you replace the inconsistency with faith, the prospect becomes even foggier. Consequently, the author concludes that Kolakowski stayed in the state of uncertainty regarding how to solve the conflict. Theoretically, he prescribes the need for faith but does not explain how to practically combine faith and doubt in one head. The Thinker often wins with the Human Being and then retreats and comes back again. The Thinker and the Human Being are not an identical opposition to rational and irrational. It is a conflict which concerns the two subject guidelines: will to know and will to exist.
Polityczne przyczyny powstania Chmielnickiego w opiniach szlachty Rzeczypospolitej
Authors: Drozdowski Mariusz R.
Published: January 2020

The article discusses the political reasons for the Khmelnytsky Uprising, as they were expressed in the opinions of the nobility of the Polish-Lithuanian Commonwealth. The outbreak of the Cossack insurrection led by Bohdan Khmelnytsky with the beginning of 1648, which from the first moment stimulated the broad strata of Ukrainian society and quickly transformed into a national liberation war, provoked terror in broad circles of the nobility. An additional factor influencing the mood of the noblemen was the growing awareness of Khmelnytsky’s political ambitions, the implementation of which was a deadly threat to the current political system of the Polish-Lithuanian Commonwealth. Therefore, the main part of the publication is devoted to discussing the views of the nobility on the subject of political motives underlying the Cossacks’ armed resistance against the Polish-Lithuanian Commonwealth. These opinions fundamentally influenced the noblemen’s assessment of the nature of the uprising. Detailed analysis is presented concerning such sources as correspondence, lauda, and sejmik instructions as well as occasional and journalistic literature. It is emphasised that there was a conviction among the nobility of the Republic of the political motives of the Cossack uprising. This conviction was based mainly on the news coming to the noblemen about Khmelnytsky’s aspirations to separate Ukraine and build an independent state entity, referred to by the nobility as the Russian Principality. Understanding of the emancipatory aspirations of the insurgents by the gentry had a huge impact on the shape of the Republic of Poland’s policy towards the events in Ukraine in the second half of the seventeenth century. Consequently, one of its main goals was to stop the movement that posed a threat to the wholeness and existence of the state.
Віра як квінтесенція концептуальної картини світу письменників-полемістів епохи раннього бароко
Authors: Slipushko Oksana , Katyuzhynska Anastasiya
Published: January 2020

The article investigates the peculiarities of the interpretation of faith as a quintessence in the conceptual world view of writers-polemists of the Early Baroque epoch. It is clarified that religious and literary controversy was caused by the adoption of the Union of Brest. In Ukrainian society, in fact, there was a schism between the supporters of different religious denominations into those who supported or rejected the Union. Therefore, the aim of the polemists was to establish the veracity of faith. The works of M. Smotrytskyj, Ch. Filalet, and H. Potij are created in accordance with the conceptual space of polemical literature of the Early Baroque epoch and represent diametrically opposed opinions on the interpretation of the Union. M. Smotrytskij and Ch. Filalet are against the Union and Catholicism, and as such express the idea of the necessity to protect the Greek Orthodox Church. Against this view, H. Potij demonstrates solidarity with the conception of the supporters of the Union, which contradicts the main ideas of M. Smotrytskij and Ch. Filalet. However, the concept of faith as the main condition of Christian life and the manifestation of spiritual values of personality acquires the highest axiological characteristic in the works of the polemists. Faith is the dominant philosophical and ideological category of the conceptual world view of the writers, a peculiar key to the implementation of the authors’ position in the controversy. The ideological sense of their works, which is embodied in religious concepts, represents the peculiarities of the outlook of the Early Baroque epoch. In the works of the polemists, the first priority is faith, which is God’s gift and creates existential dimensions of personality. Actually, faith is conceived as the basis of human life and the formation of a mentally conscious and value-oriented nation.

Published: January 2020

This paper aims to study and analyze the implementation of teacher certification regulations in Kuala Simpang, Aceh Tamiang Regency. This analysis uses several factors found by Edward III in the form of communication, resources, disposition, and bureaucratic structure. A qualitative descriptive approach is used in this paper. The results found showed that in the process of applying certification at the Aceh Tamiang education office, it had not yet proceeded effectively demanding several constraints such as lack of facilities and infrastructure, and inconsistent regulations that made it difficult for teachers. This has caused teachers to be unable and ineligible in completing lesson plans, there are still some teachers who are found to lack discipline and bad attitudes and certification are only considered for welfare and personal gain. Thus it can be stated that the certification program has not played an important role in teacher professionalism.

Plato`'s Ideas on Poetry
Authors: AVDYLI Merxhan NAZMI
Published: January 2020

In his most important and most voluminous creation â€œThe Stateâ€ (Republic, Politeia), Plato included the most characteristically philosophical concepts which were an expression of his interests. Apart various fields of teaching, such metaphysics, theology, ethics, psychology, pedagogy, State system, which result from this creation, art and poetry could not go without being included as well (including the music). Otherwise, the Plato himself, in young age, except with mathematics he also dealt with poetry by believing that he is going to be more dedicated to it. But, it seems that acquaintance with the Socrates since he was 20 years old changed his mind and he was fully committed to the philosophy. His general philosophical reviews sublimating his philosophical ideas, which arise on the basis of the idea, as an alpha and omega of every human been in the world, took Plato away from poetry by making him more and more torrential in philosophy and more and more critical, even more cynical towards the poetry.

Published: January 2020

In this research high speed milling was carried out on particles of brown coal raw fly ash, on second layer, and on third layer particles obtained from wet separation of brown coal raw fly ash. Due to milling process, median particle size d50 of raw fly ash, second layer, and third layer reduced by 46 %, 23 %, and 77 %, densities reduced by 11 %, 17 %, and 8 % respectively. Due to milling process, formation of agglomerations was observed, the standard deviation of the chemical composition of each element from the mean value reduced. After milling, high volume cementitious paste mixes were prepared with 60 % cement replacement. Due to the milling process the increase in compressive strength at 28 and 90 days was observed for raw fly ash is 59 % and 16 %, for second layer is 12 % and 15 %, for third layer and milled third layer is 78 % and 75 %. Flexural strength testing showed that due to the milling process the deflections at maximum loads have reduced considerably leading to brittle behavior of milled cementitious specimens. The testing for Mercury Intrusion Porosimetry showed that the cementitious specimens of third layer have maximum concentration of large capillary pores between 0.05 and 10 µm, whereas, all others have maximum concentration of medium capillary pores between 0.01 and 0.05 µm. Autogenous shrinkage of cementitious specimens was measured for first sixteen hours after mixing which showed that the second layer particles have the least shrinkage as compared to all other specimens.

Effective Radiant Flux for Non-image Forming Effects – is the Illuminance and the Melanopic Irradiance at the Eye Really the Right Measure
Authors: Broszio Kai , Knoop Martine , Niedling Mathias , Völker Stephan
Published: January 2020

Research indicates that intrinsically photosensitive Retinal Ganglion Cells are not evenly distributed or evenly sensitive throughout the retina. Still, most research looking into non-image forming (NIF) effects uses an integral measured quantity, illuminance or melanopic weighted irradiance, to represent the amount of light at the participantsХ eye level. This paper describes a theoretical approach to define the effective radiant flux for stimulating the ipRGCs, taking into account a spatially resolved sensitivity. Research on retinal sensitivity is scares and not yet substantial, but the methodology can easily be adopted when areas of specific sensitivity are set. Preliminary results indicate that, with similar vertical illuminances and spectral power distribution, typical office lighting solutions might have a lower NIF effectiveness than settings with higher luminances in the central part of the field of view. This could explain why research on NIF effects is inconclusive, even though reported lighting conditions are similar.
On Site Photometric Characterisation of Cement Concrete Pavements with COLUROUTE Device
Authors: Muzet Valerie , Abdo Joseph
Published: January 2020

The standard tool for characterizing road surface photometry is the reduced luminance coefficient table (or R­table), as defined in the seventies by the CIE. Since these tables are no longer representative, measuring road photometry is necessary for optimizing a lighting installation and ensuring luminance level and uniformity. The objective of the study was to characterise and follow on site the photometric characteristics of different concretes with time and traffic. A first experiment was done with two concrete formulations (broomed and water jet scrubbed concrete) located around a much circulated concrete mixer plant. The photometric characterisation of these pavements was done with the portable reflectometer COLUROUTE device during three years. The selected surface treatment was applied in a tunnel and the photometric characteristics were measured during 30 months. It was shown that the concrete pavements are more diffuse and clear than classical pavements. Their use could generate significant energy saving.

This study discusses the functional baggase activated carbon group of phosphoric acid and nitric acid using Fourier Transform Infra Red (FTIR) and its application as a copper metal adsorbent in silver craft waste in Ungga Village, Praya, Central Lombok. The production of activated bagasse carbon consists of three stages, namely first dehydration by burning bagasse until it turns into carbon, the second carbonation is heating at 500ºC, carbon results are 100-200 mesh and third, activation by soaking 50 grams of carbon in 500 mL of 20% phosphoric acid and 20% nitric acid for 12 hours. After that the carbon is dried at 110ºC and finally heated at 500ºC for 1 hour. The bagasse carbon that has been made is put into 25 mL of waste water sample with a mass of 2 grams of adsorbent. Samples were then stirred at 30, 60, 90, 120 and 150 minutes contact time variations at a speed of 180 rpm using a batch system. The optimum contact time that is used to calculate the efficiency of copper metal content reduction is by calculating the difference in the metal content of copper metal before it is adsorbed and after it is adsorbed using activated carbon baggase. Concentrations of all copper metals were analyzed using Atomic Absorption Spectrophotometer (AAS). Identification using FTIR spectrophotometer shows that carbon baggase in this study contains functional groups C = O, C = C, C-C, N = O, C = N, C-OH, CH2 and C-H. From the research it was found that the copper metal content in the sample was 14.5710 ppm. The optimum contact time on copper metal adsorption is at 120 minutes contact time which results in optimum adsorption efficiency on copper metal that is 84.88%. Activated carbon baggase is an effective adsorbent to reduce levels of copper metal in silver craft waste.

Antibacterial activity test Staphylococcus aureus and Salmonella typhihas been performed by microencapsulation product of rogo essential oil (Premnaserratifolia Linn). This study aims to determine rogo oil activity test and microencapsulation results as antibacterial S. aureus and S. typhi. The results of antibacterial activity of rogo liquid oil to S. aureus and S. Typhi bacteria showed different inhibitory power of each concentration variation of 12.5%, 25%, 50% and 100% with 100% concentration as the best inhibitor for both bacteria. While the antibacterial activity test of S. aureus and S. typhi from microencapsulated rogo oil: maltodextrin showed the difference of each variation of concentration 1:10; 1:12; 1:14; 1:16 and 1:18 with a 1:14 composition of S. aureus and 1:18 in S. typhi as the best ratio of activity power. The antibacterial activity test between liquid rogo oil and microencapsulated result shows the difference, but it can be concluded that the inhibitory power of rogo oil from microencapsulation is more inhibited than 100% rogo oil.

Regionalization of Northeast US moisture conditions: analysis of synoptic-scale atmospheric drivers
Authors: Suriano ZJ , Leathers DJ , Benjamin AE
Published: January 2020

Previous investigations have documented relationships between global-scale forcings and Northeast United States moisture conditions, yet the physical pathways from global-scale forcing to sub-regional moisture deficit or surplus are not well understood. This research uses eigenvector-based regionalization to confirm the existence of sub-regional moisture environments within the Northeast. Synoptic classification is used to derive daily weather types that impact these moisture environments, and evaluate the relationship between global and synoptic scales. The Palmer Drought Severity Index (PDSI) regionalization identifies 3 sub-regions across the Northeast with homogeneous moisture conditions including New England, the Eastern Great Lakes, and Mid-Atlantic Regions. All 3 regions’ PDSI conditions are predominantly associated with variations in precipitation, rather than thermal characteristics. The frequency of key precipitation-associated synoptic types can inform PDSI variability in the regions, where drier conditions are observed during growing seasons with a reduced frequency of precipitation-inducing synoptic types and an enhanced frequency of dry synoptic types. Variations in the frequencies of these synoptic types are partially explained by the phase of the various teleconnection patterns. In the case of the New England region, 14% of the variance in PDSI is explained by the frequency of synoptic type D2, and 12% of the variance in D2 is explained by variations in the Summer Atmospheric Drought Index. The New England region became significantly wetter (positive PDSI) from 1950 to 2016. This study suggests a partial cause of this trend is the increased and decreased frequencies of wet and dry synoptic types, respectively, both related to the phase of the Summer Atmospheric Drought Index.

Published: January 2020

Signal-to-noise ratio (SNR) estimation is essential in the unmanned aerial vehicle (UAV) orthogonal frequency division multiplexing (OFDM) system for getting accurate channel estimation. In this paper, we propose a novel non-data-aided (NDA) SNR estimation method for UAV OFDM system to overcome the carrier interference caused by the frequency offset. First, an absolute value series is achieved which is based on the sampled received sequence, where each sampling point is validated by the data length apart. Second, by dividing absolute value series into the different series according to the total length of symbol, we obtain an output series by stacking each part. Third, the root mean squares of noise power and total power are estimated by utilizing the maximum and minimum platform in the characteristic curve of the output series after the wavelet denoising. Simulation results show that the proposed method performs better than other methods, especially in the low synchronization precision, and it has low computation complexity.

Published: January 2020

Tuber peeling is an essential unit operation prior to further processing. In this research, a batch loading tuber-peeling machine, with a capacity of 10 kg/min, was designed, fabricated and tested for cocoyam, sweet potato, yam and cassava tubers. The machine was designed to operate at a speed range of 350–750 rpm and time range of 5–12 min based on the principle of surface scratching. The performance of the machine was determined with respect to the peeling efficiency, percent weight of peel and flesh loss. The results showed that the peeling efficiency increased with an increase in the shaft speed for all the tubers. Also, the flesh loss and percent weight of peel decreased with an increase in the shaft speed for cassava and cocoyam tubers but increased for sweet potato and yam tubers (p < 0.05). Effective peeling of the tubers was achieved for sweet potato and yam at all the shaft speeds and time ranges considered.
A New Technique for Improved Use of Thermal Energy from Waste Effluents

Published: January 2020

Energy sustainability and environmental protection in general are at the heart of engineering and industry discussions. Countless efforts have been devoted to improving the energy efficiency of industrial processes and specifically to harnessing their waste energy sources. One such source is waste from agro-industrial processes, which is frequently characterized by increased temperatures and high polluting potential. There are multiple available choices for exploiting energy from such waste, but this paper proposes a new alternative technique that substantially improves the efficiency. Based on the technology of leveraging a hot liquid effluent for heating a process fluid, this system introduces a third liquid to be revalorized by drying that is placed in between the hot and cold liquids. By adding stirrers inside the heat exchanger, the thermal resistance of the third fluid is reduced to a negligible level. Thus, this system has almost the same advantages as the previous one, but with the added benefit that it allows drying of a third fluid. One of the specific applications of this proposed technology is using heat from waste effluents to obtain dried food products. In the present work, it was used to dry slaughterhouse blood to obtain so-called “blood meal”, a product with a high added value that is used as pet food or organic fertilizer, and also has many other industrial applications. As shown here, the new technique outperforms existing alternatives in terms of energy efficiency and economic profitability.

Published: January 2020

Nutrient analysis of potato leaves in early growth is not sufficient for a reliable prediction of tuber yield. This hypothesis was verified based on a field experiment conducted during 2006–2008. The experimental factors were: nitrogen (N) rates (60, 120 kg ha−1), fertilizers (Urea, Urea + inhibitor—NBPT ([N-(n-butyl) thiophosphoric triamide]), and sulfur rates (0, 50 kg ha−1). Plant material for nutrient determination (N, P, K, Mg, Ca, Fe, Mn, Zn, Cu), which included leaves, stems, and stolons + roots (R+S), was sampled at BBCH 39/40. The marketable tuber yield (MTY) was in the ranges of 43–75, 44–70, and 24–38 t ha−1, in 2006, 2007, and 2008, respectively. The MTY and contents of N, Zn, and Cu, irrespective of the potato tissue, showed the same seasonal pattern, reaching the lowest values in the dry 2008. The N content in stems was the best tuber yield predictor. A shortage of K in stems and Mg and Cu in R+S, due to the opposite effect of Ca, reduced the N content. An N:Ca ratio in stems greater than 10:1 resulted in yield decrease. A reliable indication of nutrients limiting the tuber yield at the onset of potato tuberization requires data on the nutrient status in both leaves and stems.

Supplying sufficient nutrients, such as dietary energy and protein, has a great effect on the growth and rumen development of ruminants. This study was conducted to evaluate the effects of dietary energy and protein levels on growth performance, microbial diversity, and structural and physiological properties of the rumen in weaned lambs. A total of 64 two-month-old Hu lambs were randomly allotted to 2 × 2 factorial arrangements with four replicates and with four lambs (half male and half female) in each replicate. The first factor was two levels of dietary metabolizable energy (ME) density (ME = 10.9 MJ/Kg or 8.6 MJ/Kg), and the second factor was two levels of dietary crude protein (CP) content (CP = 15.7% or 11.8%). The trial lasted for 60 days. A low dietary energy level restrained the growth performance of lambs (p < 0.05). The ruminal concentration of acetate and the ratio of acetate to propionate increased but the propionate concentration decreased significantly with the low energy diet. However, the rumen morphology was not affected by the diet energy and protein levels. Moreover, a low energy diet increased ruminal bacterial diversity but reduced the abundance of the phylum Proteobacteria (p < 0.05) and genus Succinivibrionaceae_uncultured (p < 0.05), which was associated with the change in ruminal fermentation phenotypes. By indicator species analysis, we found three indicator OTUs in the high energy group (Succinivibrionaceae_uncultured, Veillonellaceae_unclassified and Veillonellaceae_uncultured (p < 0.01)) and two indicator OTUs in the low energy group (Bacteroidales_norank and Lachnospiraceae_uncultured (p < 0.01)). In conclusion, these findings added new dimensions to our understanding of the diet effect on rumen microbial community and fermentation response, and are of great significance for establishing the optimal nutrient supply strategy for lambs.
