Authors: Gürbüz Ferit
Published: November 2023

Harmonik analiz, fonksiyonel Analiz ve operatör teori alanlarında, klasik operatörlerin (= singüler, maksimal, Riesz potansiyelleri vb.) çeşitli fonksiyon uzaylarındaki eşitsizliklerinin çalışmaları çok önemli bir yer tutmaktadır. Analiz alanında pek çok konunun, çeşitli gereksinmeler sonucu ortaya konularak ve zamanın problemlerine cevap verecek şekilde geliştirilerek olgunlaştırılması, bu konular hakkında birçok çalışmanın ve eserin ortaya çıkmasına da neden olmuştur. Morrey uzayları Lebesgue uzaylarının bir uzantısı olarak kabul edilebileceğinden, Morrey uzayları üzerinde multilineer integral operatörlerin sınırlılığını incelemek doğal ve önemlidir. Bu bağlamda pek çok araştırma Morrey tipi uzaylar teorisindeki bazı boşlukları doldurmak için Morrey uzaylarını temel alan fonksiyon uzaylarına odaklanmaktadır. Pek çok araştırmacı Morrey tipi uzayların, diferensiyel denklemlerle olan ilişkisi ve diferensiyel denklemlerin Morrey tipi uzaylardaki eşitsizliklerde çok kullanılır olması nedenleriyle, Morrey tipi eşitsizlik problemlerine gitgide daha çok girmeye başlamışlardır. Bu nedenle de bu konunun önemi gittikçe artmaktadır. Fakat bu konular buranın kapsamını aştığından burada detayları geçiyoruz. Bu çalışmada, genelleştirilmiş ağırlıklı Morrey uzayları üzerinde multilineer operatörlerin sharp (keskin) tahminleri kullanılarak, Littlewood-Paley operatörü ve Marcinkiewicz operatörü ile ilgili bazı multilineer operatörlerin ağırlıklı sınırlılıkları elde edilmiştir. Bu çalışmanın iki amacı vardır. Birincisi, multilineer Littlewood-Paley ve Marcinkiewicz operatörleri için bazı sharp (keskin) eşitsizlikler oluşturmaktır. İkincisi ise bu eşitsizlikleri genelleştirilmiş ağırlıklı Morrey uzayları üzerinde multilineer operatörlerin ağırlıklı sınırlılığını ispatlamak için kullanmaktır. Bu çalışma aynı zamanda reel analiz ve ölçü teorisi hakkında biraz bilgisi olan lisansüstü öğrenciler için de uygundur.
Bacterial imprinted polymer : innovation for leptospira diagnostic kit
Authors:   , Aungwerojanawit Suraphun
Published: November 2023

Molecular imprinted polymer is a functional polymer that has gained attention in many researches due to its abilities to recognize and bind the molecules which are imprinted onto the polymer. In this study, we aimed to challenge the imprinting technique using more complex morphology of bacteria. Thus, we used Leptospira as the template, since; Leptospira has a unique spiral structure. Prepolymer of poly (methyl methacrylate)-co-(hydroxyethyl methacrylate) was successfully synthesized via photopolymerization using benzophenone and triethylamine under UV radiation (λ≈250 nm). The prepolymer was then spin-coated onto the glass coverslip and stamped with Leptospira template then cured under UV light for 24 hour to obtain the imprinted polymer (IP) film. IP film was then washed with 3%(w/v) sodium hydroxide solution under sonication to remove the bacterial template. The IP film was observed by field emission electron microscope and atomic force microscope. The results showed that Leptospira were successfully imprinted onto the polymer film surface and maintain the spiral structure of the bacteria.
Functional characterization of hemocyte homeostasis associated protein, HHAP in two species of crustaceans
Authors:   , Apitanyasai Kantamas
Published: November 2023

Hemocyte homeostasis-associated protein (PmHHAP) has been reported as a viral responsive protein that plays an important role in controlling hemocyte homeostasis in shrimp Penaeus monodon. In this study, the role of PmHHAP in regulating apoptosis in shrimp was investigated. In vivo gene silencing of PmHHAP could induce the high level of apoptosis in shrimp hemocytes and altered the expression of apoptosis-related genes particularly PmCasp and PmCaspase. Moreover, PmHHAP was able to bind to PmCasp and the rPmHHAP protein could decrease apoptosis in the rPmCasp-treated hemocytes cells. These results indicated that PmHHAP is an anti-apoptosis protein that regulates hemocyte homeostasis by inhibiting apoptosis in P.monodon. Yeast two-hybrid and co-immunoprecipitation revealed that PmHHAP binds to an anti-apoptosis protein of white spot syndrome virus, WSSV134. The viral protein WSSV134 is a late protein of WSSV which is initially expressed after 24-hour post infection (hpi) and is likely involved in viral propagation. Co-silencing of PmHHAP and WSSV134 prior to WSSV infection showed significant increase of caspase activity, which was higher than silencing only PmHHAP or WSSV134, suggesting that these two proteins might work concordantly to control apoptosis during WSSV infection. Suppression subtractive hybridization (SSH) of PmHHAP silenced shrimp hemocytes identified several viral responsive genes as well as hemocyte homeostasis-related genes such as the transcription factor ATF-β, cathepsin L, lactate dehydrogenase, ferritin and inhibitor of apoptosis (IAP), some of which should be selected for further investigation. In addition, a homolog of HHAP in crayfish Pacifastacus leniusculus with 47% similarity to PmHHAP was functional characterized. PlHHAP was detected in all examined tissues but highly expressed in intestine and gill. Surprisingly, PlHHAP was found to play important role in bacterial but not viral defense in contrast to PmHHAP. PlHHAP transcript remained unchanged upon WSSV infection but dramatically increased upon bacterial Aeromonas hydrophila B1 challenge. Furthermore, suppression of PlHHAP resulted in increasing the number of bacteria in intestine but did not affected hemocyte apoptosis or the expression of genes (CHF, astakine1, astakine2, and IGFBP7) involved in crayfish hematopoiesis and hemocyte homeostasis suggested that HHAP from different crustacean species have different functions in defense against invading pathogens.
Molecular characterization of isoamylases from cassava tuber Manihot esculenta Crantz ‘KU50’
Authors:   , Panpetch Pawinee
Published: November 2023

Starch debranching enzyme or isoamylase (EC.3.2.1.68), an important enzyme in starch metabolism, catalyses the hydrolysis of α-1,6 glycosidic linkages of amylopectin. In this work, cassava isoamylase genes were isolated from cDNA generated from total RNA from tubers of Manihot esculanta Crantz cultivar KU50 by RT-PCR and analysed by agarose gel electrophoresis. Three putative isoamylase genes, MeISA1, MeISA2 and MeISA3 were identified and amplified excluding the fragments encoding their transit peptides. Full length of MeISA3 gene was obtained by 5’ Rapid Amplification of cDNA Ends (5’ RACE). The mature MeISA1 and MeISA2 were successfully amplified and cloned into a pETDuet1 vector, while the mature MeISA3 was amplified and cloned into a pET21b and sequenced. The ORFs of mature recombinant MeISA1, MeISA2 and MeISA3 genes were 2,292, 2,649 and 2,127 kb, encoding 763, 882 and 708 amino acid with substantial similarity to StISA1, StISA2 and StISA3 from potato at 84.4%, 68.9% and 80.9%, respectively. Then, rMeISA1 and rMeISA2 were coexpressed and rMeISA3 was single expressed in Escherichia coli SoluBL21(DE3) and purified by HistrapTM column. Analysis by SDS-PAGE and immunoblot showed approximate molecular weights of 87, 99, and 80 kDa, respectively. Debranching activity was only detectable in the fractions where both rMeISA1 and rMeISA2 were present. The heteromultimeric DBE from 4-5 h induced culture analysed by gel filtration chromatography and Western blot showed combinations of rMeISA1 and rMeISA2 at ratios of 1:1 to 1:4. Pooled fractions of rMeISA1/rMeISA2 with DBE activity and the purified rMeISA3 were used for enzyme characterisation. Both rMeISA1/rMeISA2 and rMeISA3 showed the optimum activity at 37ºC but their optimum pH were at 7.0 and 6.0, respectively. Enzyme activity of rMeISA1/rMeISA2 was enhanced by Co2+, Mg2+ and Ca2+, whereas rMeISA3 activity could be significantly activated by Mn2+ and Co2+. Cu2+ was a strong inhibitor for both enzymes. Debranched amylopectin products analysed by HPACE-PAD showed chain length distributions typical of plant debranching enzymes with DP from 6 to 20 with major products around DP 10 to 12. rMeISA1/rMeISA2 were specific for amylopectin while rMeISA3 showed the highest activity on beta-limit dextrin. However, they could hardly hydrolyse pullulan at all, indicating their classification as isoamylase-type debranching enzyme. The debranching activity of rMeISA1 and rMeISA2 required their association as heteromeric complexes.
MECHANISM OF ACTION OF AVICENNIA MARINA HEARTWOOD EXTRACT AND AVICEQUINONE C ON HUMAN DERMAL PAPILLA CELLS ISOLATED FROM ANDROGENIC ALOPECIA PATIENTS
Authors:   , Numsawat Sukanya
Published: November 2023

Androgenic alopecia (AGA), is a genetically determined disorder associated with an increased production of the hormone 5-alpha -dihydrotestosterone which is formed from testosterone (T) by the enzyme activity of 5-alpha-reductase. Previously, crude extracts prepared from heart wood of Avicennia marina (AM extract) and its active constituent, namely avicequinone C (AC) were found to be able to inhibit the enzyme activity of 5-alpha-reductase. In this study, the possible mechanism of the AM extract and AC compound on the biochemical actions of hair growth was evaluated by using dermal papilla cells (DPCs) isolated from AGA patients. The studies showed that AM extract (10µg/ml) and AC compound (10µM) could inhibit the activity of 5-alpha-reductase enzyme causing the reduction of 5-alpha -dihydrotestosterone formation by 74% and 68%, respectively. Independently, both AM extract and AC compound could also significantly inhibit the translocation of the bound-androgen receptor complex into the nucleus which is the site of T and 5-alpha -dihydrotestosterone action. Both inhibitory actions of 5alpha-reductase and nuclear translocation by AM and AC appeared to have subsequent effects on the increase in the mRNA expression of VEGF and HGF which play important roles in the formation of new blood vessels associated with the hair growth (angiogenesis). In summary,the results from this study revealed the mechanism of action of AM and AC on hair growth in DPCs which is useful for supporting the development of Avicennia marina extract and pure AC compound as a potential product to prevent and treat AGA patients.

Authors:   , Chimpibul Wichchulada
Published: November 2023

The aim of this work is to fabricate the encapsulated fish oil particles for shrimp feed. The co-encapsuted fish oil with BHT (Butylated hydroxytoluene as the antioxidant) particles size is 1.00 ± 0.74 mm prepared solvent displacement method using ethylcellulose as the polymeric material. The morphology of these particles were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The encapsulated fish oil-BHT particles were tested to investigate the stability properties. The results indicate that encapsulated fish oil-BHT processes better thermal stability, oxidative stability and shelf life stability than unencapsulated fish oil. Moreover, encapsulated fish oil-BHT particles were added into the shrimp feed to increase the content of unsaturation of polyunsaturated fatty acids (PUFAs) in shrimp diet. The shrimp feeds were prepared with two different methods: 1) mixing encapsulated fish oil-BHT particle to shrimp feed paste for pelting machine before pelleting, 2) spraying encapsulated fish oil-BHT particle suspension onto the shrimp feed pellets. Both methods gave feed with minimal degradation of unsaturation functionality. In addition, Litopenaeus vannamei fed with feed containing the encapsulated fish oil-BHT particle shows better health such as, growth, weight, length and immunity index than those fed with unencapsulated fish oil containing feed.
Increasing final concentration of l-lactic acid via fed-batch fermentation by Bacillus aerolacticus BC-001
Authors:   , Wutthimongkholchai Anunyaporn
Published: November 2023

Polylactic acid (PLA) now gains many interests due to its versatile applications. Nonetheless, cost competitiveness with the existing petroleum based plastic is the key issue in biobased plastic industry. One plausible way to reduce production cost of biobased plastic can be accomplished by low cost feedstocks. Therefore, high final product titer at the end of batch run is necessary. However, batch fermentation using high substrate concentration usually suffers from low yield and productivity due to substrate repression. In this work, we tested for the ability of Bacillus aerolacticus BC-001 to ferment glucose at high concentration up to 200 g/L and study using fed-batch fermentation in both flask and 5 L stirred fermentation cultures. In flask, the results revealed that B. aerolacticus BC-001 was able to ferment glucose at 200 g/L at the close yield and productivity to those obtained from 100 g/L glucose. Moreover, final lactate titer be increased up to 192 g/L with the acceptable yield of 0.90 g/g and productivity of 3.55 g/L×h by intermittent fed-batch fermentation. In case of fermentation in 5 L fermentor, via batch fermentation with sole glucose solution, 104.24 g/L lactate titer with the productivity and yield of 5.79 g/L×h and 0.85 g/g respectively was obtained. When increasing the initial glucose concentration to 125-200 g/L, substrate repression was appeared. To solve this problem, different fed-batch fermentationห were conducted. The most effective feeding program was intermittent fed-batch fermentation. The final lactate titer of 145.08 g/L with productivity of 3.72 g/L×h and yield of 0.95 g/g was obtained. Moreover, adding glucose solution supplemented with (NH4)2SO4 at the C/N ratio of 40:1 was able to improve final lactate titer to 160.84 g/L with 3.58 g/L×h and 1.02 g/g. Therefore, compared with typical batch fermentation, intermittent fed-batch fermentation with glucose solution supplemented with (NH4)2SO4 at the proper C/N ratio produced higher final lactate concentration for 54.30% with the increasing yield by 11.76%. Most importantly, this technique could prolong high production rate at 11.70 g/L×h until 18 h fermentation.

Authors:   , Tunyatarinun Natpatsorn
Published: November 2023

Mushrooms have been used as food and for therapeutic purpose for decades. Indeed, various compounds derived from them have potential biological activities. The present study aims to explore the free radical scavenging properties of peptides derived from the edible mushroom Astraeus hygrometricus. In this work, peptides from A. hygrometricus protein hydrolysates attainable with microbial proteases (Alcalase®, Flavourzyme® and Neutrase®) were prepared and their antioxidant activities were determined. Peptide fractions derived from A. hygrometricus hydrolyzed by 1% Alcalase®, showed the highest DPPH and ABTS radical scavenging activities with IC50 values of 13.40±0.48 and 5.53±0.59 µg/mL, respectively. Peptide fractions were obtained using molecular weight cut-offs of 10, 5, 3 and 0.65 kDa membranes and their antioxidant properties were further analyzed. Among the fractions, MW < 0.65 kDa (F5 fraction) exhibited high levels of free radical scavenging activities towards DPPH and ABTS with IC50 values of 4.84±0.26 and 1.49±0.39 µg/mL, respectively. The F51 fraction from the Superdex® 75 column was identified as having the highest scavenging activities on DPPH and ABTS radicals with IC50 values of 32.47±1.16 and 15.58±0.73 µg/mL, respectively. Furthermore, the F51 fraction could protect hydroxyl radical-induced DNA damage as shown in pKS, pUC19, and pBR322. In addition, fraction F51 was used to determine antiproliferative activity. The results showed that purified peptide fraction F51 was not cytotoxic on normal and cancer cell lines, and the lung cancer cell line (Chago-k1 cell) had the highest antiproliferative activity. Moreover, fraction F51 was used for determining the induction of apoptosis that used flow cytometry and the caspase 3, 8 and 9 activities analysis method. The results indicate that purified peptide fraction F51 could induce the highest apoptotic cells and caspase 3, 8 and 9 activities on Chago-k1 cell at 72 hours. Furthermore, the peptide fraction F51 was purified using RP-HPLC and sub-fractions F51-1 to F51-5 collected. The result was found to possess the highest antioxidant activity on fraction F51-5. Finally, the  amino acid sequences of sub-fractions F51-1 to F51-5 were identified using MS/MS (ESI-Q-TOF). The amino acid sequences of the purified peptide fractions F51-1 to F51-5 in respective order were as follows: Val-Thr-Thr-His-Lys-Thr-Val-Thr-Lys-His (VTTHKTVTKH, 1152 Da), Met-Pro-His-His-Tyr-Thr-Ile-Phe-Ala-Leu-Gly-Thr-Gln-Ser-Arg-Pro-Ser (MPHHYTIFALGTQSRPS, 1942 Da), Pro-Ser-Arg-Gly-Ser-Glu-Arg-Ala-Arg-Ala (PSRGSERARA, 1086 Da), Thr-Leu-Ser-Asn-Leu-Gly-Leu-Val-Leu-Val-His (TLSNLGLVLVH, 1165 Da) and Leu-Thr-Asn-Ser-Pro-Trp-Ala-His-Ala (LTNSPWAHA, 996 Da). Hence, the purified peptide fraction F51 could be used as a natural antioxidant for drug development.

Authors:   , Cheunchob Thadsaneeya
Published: November 2023

The purposes of this research were to explore tyrosinase inhibitory and anti-oxidant activities of Sacha Inchi leaf, and to develop skin lightening and anti-aging product for a facial cream from the crude extract of Sacha Inchi leaf. From the results obtained of this research, methanolic crude extract showed potent tyrosinase inbibition activity (IC₅₀ 34.55 µg/mL) whereas dichloromethane crude extract did not inhibit the tyrosinase activity. Therefore, the methanolic crude extract was selected for further studies on superoxide anion radicals scavenging capacity using photochemiluminescence (PCL) assay. In the result, antioxidant capacity of the crude methanolic extract was 16.1 µmol TE/g extract and 17.8 µmoL AE/g extract, cytotoxic effect of methanolic crude extract was examined on mice fibroblast normal (L929) and Hepatocellular carcinoma (HepG2) cell lines, respectively. The IC₅₀ of the methanolic crude extract exhibited on L929 cells showed at 1,641 µg/mL and HepG2 cells was 358 µg/mL. Four formulations were prepared in the form of oil-in-water emulsion containing the crude metanolic extract. The sensory evaluation, more than 90% of volunteers were accepted in formulation 3, with color, texture, spreadability, stickiness and overall of product. In the biological activities of formulated cream, the result revealed that methanolic extract showed tyrosinase inhibition and radicals scavenging properties. In addition, the formulation 3 was stable under accelerated conditions. This study suggests a potential use of the methanolic crude extract from Sacha Inchi leaf as an active ingredient in cosmetic products.
ANALYSIS OF ALLERGENS FROM BLACK TIGER SHRIMP (Penaeus monodon) BY COMBINING TWO-DIMENSIONAL GEL ELECTROPHORESIS WITH RS-ATL8 REPORTER CELL LINE
Authors:   , Jarupalee Thanyapat
Published: November 2023

Food allergy is an immediate hypersensitivity reaction. Specific IgE is generated against allergens, and binds to the specific IgE receptor on the surface of basophils and mast cells. Allergen binding induces IgE cross-linking that triggers these cells to release chemical mediators such as histamine, prostaglandins and leukotrienes. Symptoms of allergic reactions vary from mild irritation to anaphylaxis and life-threatening. Black tiger shrimp (Penaeus monodon) is an important aquaculture species in Asia and is the common cause of food allergy in Thailand. One of the important problems in management of shellfish allergy is the lack of accurate diagnostic assay because the biological and immunological properties of allergens in the black tiger shrimps have not been well characterized. This study aims to investigate the reactive pattern of serum IgE from shrimp allergic patients to raw and cooked protein extract from black tiger shrimps and to identify shrimp allergens that can trigger IgE crosslinking by combining two-dimensional gel electrophoresis (2-DE) and RS-ATL8 reporter cell line. ELISA using sera from 24 shrimp allergic subjects, indicated that there were significant differences in reactivity to the raw and cooked shrimp extracts (P= 0.0093). Allergic serum IgE reacted stronger to raw shrimp extract than cooked shrimp extract. Consistent with these results, in SDS-PAGE, raw shrimp extract contained more protein bands than in the cooked extract. Western blot demonstrated that there was the major IgE reactivity area at 32-39 kDa in both raw and cooked shrimp extract. Eighteen of 24 patients (75%) and all patients (100%) had specific IgE to proteins in the range of 32-39 kDa in cooked and raw shrimp, respectively. The minimum concentration of crude shrimp extract to induce IgE cross-linking as measured by RS-ATL8 cell line were 10 fg/ml and 100 fg/ml in raw and cooked shrimp extract, respectively. The ten spots excised from 2-DE did not induce IgE cross-linking in RS-ATL8 cell line. The eluted protein from one-dimensional gel electrophoresis at the 115 and 38 kDa bands from raw shrimp extract induced an IgE cross-linking and the proteins were analysed by mass spectrometry. Some novel proteins were identified with the possibility of novel allergen. These results may be useful for shrimp allergy diagnostic test in the future.

Examining the Impact of National Education Councils on Education Management Policies
Authors: Balıkçı Abdullah
Published: November 2023

The aim of this study is to make inferences about education management policies based on the decisions taken in the National Education Councils (1-20). In the study, qualitative research method and document analysis were used. The study was also based on National Education Council (NEC) decisions, which are available on the official website of the Ministry of National Education, Board of Education and Discipline, and whose full texts have open access. Some of the decisions taken in NECs involve various issues related to educational management. As a result of the analysis of the research data, six themes emerged. These; legislation, organizational structure, curriculum, educational practices, environment and teacher- education manager. Decisions regarding these themes are made at different education levels (pre-school, primary education, secondary education, higher education). In addition, not only education levels are used in determining educational management policies within NEC decisions; many factors (legislation, curriculum, educational practices, environment, teacher-education administrator) are effective. The themes identified in the study are interconnected and supportive of each other. Based on the findings of this study, it is recommended to establish a control mechanism to better monitor education management policies based on the decisions taken in NECs to understand whether or not they are implemented or to what extent they are implemented.

Wie wirkt sich Arbeitslosigkeit und Kurzarbeit während und nach dem COVID-19 Lockdown auf psychische Gesundheit aus? Ausgehend von einer Theorie der latenten Deprivation wird die Verknüpfung zwischen Erwerbsverläufen und psychischem Wohlbefinden zwischen Ende März 2020 und Mitte Juli 2020 untersucht. Datengrundlage der Analyse ist das Austrian Corona Panel Project (ACPP) mit 1500 Befragten pro Welle. Die Befunde unserer Untersuchungen zeigen, dass Arbeitslosigkeit sich signifikant und negativ auf psychisches Wohlbefinden auswirkt. Insgesamt stützen die Ergebnisse die Hypothese, dass die SARS-CoV-2-Pandemie und die politischen Maßnahmen zur Bekämpfung der Pandemie einen nachhaltigen Effekt auf das psychische Wohlbefinden für von Arbeitslosigkeit Betroffene hatten.
Die soziale Gestaltung einer ökologischen Steuerreform?
Authors: Six Eva , Lechinger Vanessa
Published: November 2023

Die Herausforderung einer ökosozialen Steuerreform ist einerseits über die Erhöhung der Preise von CO2-Emissionen, Anreize für ein umweltfreundlicheres Verhalten zu setzen und andererseits die soziale Sicherung aller betroffenen Personen sicherzustellen. Im Rahmen dieses Beitrages analysieren wir die Effekte der Einführung einer CO2-Steuer in der Höhe von 50€/tCO2 auf fossile Treib- und Heizstoffe im österreichischen, privaten Haushaltssektor. Zudem werden potentielle Rückvergütungsmaßnahmen diskutiert. Der Fokus liegt dabei auf der Analyse von drei unterschiedlichen Varianten des Ökobonus in Hinblick auf die Bereiche Verteilungswirkung, praktische Durchführbarkeit und Armutsvermeidung. Die statische Simulation der Reform erfolgt auf Basis des Mikrosimulationsmodells TAXSIM. Unsere Ergebnisse zeigen, dass durch die Einführung einer CO2-Steuer reichere Haushalte, aufgrund ihrer höheren Konsumausgaben auch höhere Steuerbeträge zahlen müssen. Betrachtet man die Verteilungswirkungen jedoch im Verhältnis zum Einkommen zeigt sich eine stark regressive Wirkung, da ärmere Haushalte einen höheren Anteil ihres Einkommens für Heiz- und Treibstoffe aufwenden müssen. Die Einführung eines pauschalen Ökobonus kann der regressiven Wirkung einer CO2-Steuer nur begrenzt gegensteuern, während eine einkommensabhängige Variante auf Basis des äquivalisierten Haushaltseinkommens am besten Armut vermeiden kann. Aufgrund der schwierigen Durchführbarkeit in der Praxis, erscheint jedoch eine einkommensabhängige Version auf Basis des individuellen Einkommens am geeignetsten, da diese einfacher mit dem österreichischen Steuersystem vereinbar ist. Um zudem Anreize so zu gestalten, dass besonders auch armutsgefährdete Personen zu umweltfreundlichen Alternativen umsteigen können, müssen zusätzliche Maßnahmen, wie etwa Investitionen im Bereich Heizen und Mobilität durchgeführt werden.

In der Berechnung der Kosten einer Jobgarantie für Langzeitbeschäftigungslose in Österreich ist ein Fehler unterlaufen wodurch sich die zusätzlichen Kosten für einen Arbeitsplatz pro langzeitbeschäftigungsloser Person/pro Jahr auf 8228,8 € erhöhen (ursprünglich wurde mit Kosten in der Höhe von 6.7858 €gerechnet). Die Neuberechnung wurde mithilfe des Brutto-Netto Rechners des Finanzministeriums 2020 durchgeführt (das ist die zum Zeitpunkt der Korrektur früheste Verfügbare Version). Dadurch kam es zu Veränderungen der Dienstgeberabgaben in den Ausgaben und Rückflüssen (8.091,6 € anstelle von 8.164,4 €). Die Veränderung der Kosten, der Fehler in der ursprünglichen Berechnung, ist auf eine Überschätzung der SV-Beiträge der ArbeitgeberInnen zurückzuführen. Dieser wurde für die Neuberechnung korrigiert und anstelle von 7.643 € wurde der Betrag auf 6.126 (inkl. BMVK) € angepasst. In Summe würde die Finanzierung von Vollzeitarbeitsplätzen für 40.000 Langzeitbeschäftigungslose das Budgetdefizit im ersten Jahr nach den korrigierten Berechnungen um 329 Mio. Euro erhöhen (anstelle von 271,4 Mio. Euro in der ursprünglichen Berechnung). Für den Fehler und etwaige Unannehmlichkeiten möchten sich die Autoren hiermit aufrichtig entschuldigen.

Published: November 2023

Vor dem Hintergrund der steigenden Relevanz und Aufmerksamkeit für Gentrifizierung wurden in den letzten Jahren vermehrt Methoden entwickelt, um Gentrifizierungsgebiete zu identifizieren. Die vorliegende Studie entwickelt, aufbauend auf dem internationalen Forschungsstand, erstmals eine Methode zur quantitativen Identifizierung solcher Gebiete in Wien und wendet diese auf Basis von kleinräumigen sozioökonomischen und immobilienwirtschaftlichen Daten für den Zeitraum 2011 bis 2016 an. Neben den empirischen Befunden bietet die Studie damit eine methodische Innovation gegenüber der vorhandenen Forschung zu Gentrifizierung in Wien, die sich bis dato auf Fallstudien einzelner Viertel oder Sektoren am Wohnungsmarkt beschränkt. Darüber hinaus leistet die Studie einen Beitrag zur breiteren sozialgeographischen Stadtforschung in Wien, die bisher vorwiegend auf sozioökonomische Veränderungen fokussiert und immobilienwirtschaftliche Veränderungen nicht näher in den Blick nimmt. Die Ergebnisse werden vor dem Hintergrund der vorhandenen Literatur diskutiert und offene Fragen für die zukünftige Forschung zu Gentrifizierung in Wien identifiziert.

Poland: Policies dealing with the inflation crisis
Authors: Grodzicki Maciej J. , Surmacz Tomasz , Mozdzen Michal
Published: November 2023

The aim of the national case study is to investigate the recent inflationary developments in Poland, against the background of tendencies present in the EMU economies. It provides insights into the structural aspects of inflation in Poland, as well as into its outcomes for growth prospects and income distribution. For this purpose, the main tendencies in nominal wages and corporate mark-ups, as well as the up-to-date strategies of the government and domestic trade unions are analysed.

The study combines quantitative analysis with qualitative overview of policy making and the activities of social partners, including the trade unions. First, we demonstrate that post-pandemic inflationary dynamics in Poland are similar to the CEE average, yet much higher than in the EMU. This can be attributed to the composition of the consumption basket, with a relatively high share of energy, food and transport expenses. There are also inflationary pressures from a strong expansion, as reflected in low unemployment, full capacity utilisation and exchange rate depreciation.
Second, we identified strong redistributive effects of the inflation in Poland, as reflected in declining real wages and labour share in national income. We see extraordinarily high mark-ups and profits in the business sector, particularly in 2021. Finally, we identify the social dialogue in Poland as conflictual, with virtually no coordinated efforts to limit the rate of inflation. Under such conditions, government policies are of even higher importance. These focused primarily on mitigating the social costs of inflation for households, and mostly took form of economy-wide tax cuts and transfers.

Most of you will know that the major US science-funding agencies require the work they fund (from the public purse) to be made available as open-access to the public that funded it.  And it’s hard for me to imagine anyone sees that requirement as anything other than straightforwardly just.

Published: November 2023

Social media has a big impact on everyday life, one of which is to communicate or to get information. Therefore, the development of social media applications makes people use social media applications to find information via the internet. The Instagram applications is one of the most popular social media because it has different topics based on post in the from of images or videos. Therefore, it is very difficult to identify a topic manually. One way to get implied information on social media is through topic modeling. This research was conducted to analyze the application of the LDA method to identify what topics are on Instagram at Multi Data Palembang University. The topics chosen in this study were obtained from LDA based on coherence values. This research uses 2 models, namely random forest and decision tree. Each model tested will produce different accuracy, precision, recall, and f1-score values. Tests were carried out on the LDA labeling dataset and manual labeling, the test results on the LDA labeling dataset were very good using the random forest model with an accuracy values of 78%, precision 80%, recall 66.66%, and f1-score 72.72%.

Fine particle liberation in saturated porous media under non-isothermalfluid flow
Authors: Zhai Xinle , Atefi-Monfared Kamelia
Published: November 2023

Decline in well productivity is a widely reported phenomenon and a critical challenge negatively impacting energy and water operations in deep geological reservoirs [1, 2]. A key contributor to this problem is the detachment of in-situ fine particles present in the porous matrix, which will then migrate and travel through the porous formation until getting strained within thin pore throats resulting in pore clogging and therefore permeability damage [3]. The detachment of in-situ fine particle occurs when the mechanical equilibrium of the attaching (i.e., electrostatic and gravity forces) and the detaching forces (i.e., drag and lifting forces) exerted on the particle is disturbed. In geological reservoirs, the equilibrium of in-situ fines can be disturbed as a result of fluid flow velocities, temperature alterations in the porous formation, or reduced ionic strength of the in-situ fluids [4]. Fines migration and straining can also alter in-situ stresses through generating pore pressure changes as a result of permeability damage [5].

Multiple experimental and numerical studies have evaluated the mechanisms involved in detachment, migration, and straining of in-situ fines and the clogging of pore fluid channels [6, 7]. A number of studies have also focused on evaluating temperature-induced particle mobilization [8]. Variations of the electrostatic force with temperature is often explained through the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory [9]. In a saturated porous formation containing in-situ fines, Dielectric permittivity of pore fluid decreases with an increase in temperature, weakening the repulsion between the fine clay particles and the sand surface [10]. As a result, the attaching electrostatic forces are lower under higher temperatures.

This study focuses on developing a theoretical model to evaluate the impact of the size distribution of in-situ fine particles on non-isothermal fluid flow induced fine mobilization in saturated porous media. Expressions for drag force and electrostatic force are obtained based on the DLVO theory considering coupled effects of fluid velocity, temperature, and ionic strength of in-situ fluids. The main parameters adopted in the proposed model are presented in Table 1. The proposed model predicts the maximum concentration of retained fines considering coupled effects from temperatures and pore pressures. Results are valuable for estimating permeability damage and well productivity during enhanced geothermal operations.

O presente artigo apresenta tais transformações e possibilidades que tais máscaras foi assumindo ao longo dos anos, a fim de discutir a relação de tradição e contemporaneidade na utilização do mascaramento influenciado por Mapiko na cena atual de Maputo.
Ovarian non-Hodgkin lymphoma with central nervous system involvement: A case report
Authors: Nyamu Brenda , Cheserem Eunice
Published: November 2023

Background: Ovarian lymphoma is rare. Extranodal non-Hodgkin lymphoma (NHL) represents 0.5% of malignant genital diseases. Due to its rarity, there are no accepted treatment protocols. Diffuse large B cell lymphoma (DLBCL) has a central nervous system (CNS) involvement rate of 3-5%.

Case presentation: A 38-year-old presented to the gynecological oncology clinic with abdominal pain and distension. Her tumor marker CA-125 levels were elevated. She developed right-sided facial nerve palsy and blindness. A diagnosis of aggressive NHL with a differential of DLBCL was made by histopathological and immunohistochemical examination of the excised ovarian tissue. A head computed tomography scan revealed subtle enhancing opacity suspicious of lymphomatous deposits. She was lost to follow-up after ten months of chemotherapy and cranial radiotherapy.

Conclusion: Primary lymphoma of the ovary is rare, and the prognosis is often poorer when compounded with CNS involvement. Because of poor prognosis in the presence of CNS involvement, this case highlights the need for timely diagnosis and management.
