Authors: Altan Mustafa Zulkuf
Published: February 2022

The shifting landscape of entrepreneurship education and research indicate that it is important to create a transition and adapt in order to continue offering impactful enterprising education for the next generation of entrepreneurs. Most current classroom practices, models, suppositions about learning and ways to deal with learning and educating by and large uncover that they can't prepare people for these new and sudden difficulties since they are solely founded on a universe of yesterday. The globe needs more imaginative and inventive people who can find answers for both present and future worries in each area of the community they live in. How might this vision be cultivated? Who can carry this vision to materialize? This paper features the significance of executing an enterprising education implemented by those who are enterprising themselves in order to cultivate the desired mindset to establish an an enterprising and imaginative educational ecocommunity for a just, better and harmonious world.

A distinction of k-hyponormal and weakly k-hyponormal weighted shifts
Authors: Li Chunji , Lee Mi , Xiao Yiping
Published: February 2022

Let ?(x) : ?x/2, ?2/3, ?3/4, ?4/5, ... be a sequence with a real variable
x > 0 and let W?(x) be the associated weighted shift with weight sequence
?(x). In [17], Exner-Jung-Park provided an algorithm to distinguish weak
k-hyponormality and k-hyponormality of weighted shift W?(x), and obtained sn
> 0 for some low numbers n = 4,..., 10, such that W?(sn) is weakly
n-hyponormal but not n-hyponormal. In this paper, we obtain a formula of sn
(for all positive integer n) such that W?(sn) is weakly n-hyponormal but not
n-hyponormal, which improves Exner-Jung-Park?s result above.

Published: February 2022

Vegetation cover is considered one of the most important factors that affect weather, climate, and the environment. This paper aims to study the correlation between land surface temperature and the Vegetation Indices using Landsat data in Duhok Governorate, Iraq. Landsat-8 images were taken for December, April, July, and October in 2019. Geographic Information System ArcGIS 10.2 package has been used to calculate the results. The Normalized difference vegetation index NDVI, Green ratio vegetation index (GRVI), and land surface temperature (LST) have been computed. The results showed that were a strong positive relationship between vegetation indices during winter, spring, summer, and fall seasons. The correlation coefficient values ranged from (0.9) in winter, (0.96) in spring, (0.95) in summer and (0.89) in autumn seasons. Also, the results showed a strong inverse correlation among LST and NDVI, GRVI indices during winter, spring, summer, and autumn seasons. The strongest correlation between land surface temperature and the Vegetation Indices was in the Spring Season. These correlations can be used to study vegetation health, drought.

Authors: Abdul-Hussain Muhaiman Ali , Mohamad Haidar J.
Published: February 2022

Hard disk drive (HDD) and storage media have the potential to revolutionize future information technology. Heat-assisted magnetic recording (HAMR) is a promising method for increasing hard disk storage density and it is one of the applications of this study. The essential component of nanoscale spintronic devices is spin current. The simulation of a thermal gradient to generate a pure spin current using an ultrafast femtosecond (fs) laser in a multilayer thin film is presented. The trilayer sample (ferromagnetic/spacer/magnetic insulator) is the candidate to achieve the spin current. Ultrafast laser with fs pulse width simulated to creates a spin diffusion spark. These pulses penetrate within the trilayer reaching the magnetic insulator due to the penetration depth that record the effect. COMSOL Multiphysics software® is used to simulate the thermal behavior within the trilayer with three-dimensional (3-D) view. The thickness of the ferromagnetic layer (Ni81Fe19) has been shown to generate a high-temperature gradient within the magnetic insulator and therefore a larger spin current.
Effect of Climate Change on Spring Massive Sand/Dust Storms in Iraq
Authors: Halos Saadiyah H. , Mahdi Salah
Published: February 2022

Sand and Dust storms are considered a major natural disaster that cause many damages to society and environment in Iraq and surrounded deserted regions. Two spring sand/dust storms on May in two different years were synoptically analyzed. These sand/dust storms were compared in terms of dust surface concentration from NMMB/BSC-Dust model, sea level pressure, surface wind vector, satellite vegetation index and stations rainfall. The findings of this sand/dust storms comparison indicate that Iraq in spring may be affected by two types of wind one dust storm initiated by Shamal which have long occurred in this region and caused frequent dust storms in spring and second by Al-Khamsian. Dust storm in 2012 is massive than sand/dust storm in 2018 where the highest dust surface concentration is reached to (7700 μg/m3) in 22 May 2012 and about (3100 μg/m3) in 11 May 2018. Increase in vegetation cover over Iraq in 2018 was about 23% more than in 2012. Rainfall level in season (2017-2018) was higher than in rainfall season (2011-2012) in Iraqi dust sources regions. Low pressure gradient, less strong wind, rise in rainfall level and enhancement in vegetation cover are contributed to decrease the storm concentration of 2018 roughly by half.

Authors: Ismail Hidayatullah , Fatah Nasrul , Arni Jani
Published: February 2022

Tafsir Al-Qur'an Al-Karim which is the great work of Mahmud Yunus who is known as one of the productive Indonesian scholars has produced written works in various Islamic disciplines. This interpretation is always interesting to study because its style is thick with the nuances of ijtima'i as a form of response to the realities of life that exist in society. Among the descriptions found in many places in this commentary is the importance of maintaining unity and integrity and avoiding disintegrity. So this paper aims to analyze Mahmud Yunus's thoughts on the unity of the people with a descriptive approach to analysis based on library data. The findings of this study found that efforts to realize unity among Muslims must continue to be carried out even though big challenges always exist. Challenges to the union came from external and internal. External, namely from parties outside Islam who do not want the realization of Muslim unity. While internal comes from within the body of Muslims caused by not adhering to the Qur'an and sunnah and the nature of ta'ashub. As a solution offered is to strengthen moral education or tarbawi akhlaqi in social life

Published: February 2022

Introduction: Therapeutic plasma exchange is used to manage immune-mediated diseases as early as 1970th. Nevertheless, the evidence beyond the therapeutic indication is still anecdotal and depends on observational data and national registries from different parts of the world. Aim of the Study: To review the use of therapeutic plasma exchange (TPE) to manage different conditions in the Dubai Hospital-nephrology department and benchmark against standard indications categories by American Society of Apheresis (ASFA) guidelines.

Methods: The study included all adult patients who performed TPE in Dubai Hospital during 24 months period from January 2017 until December 2019. Patient demographics, indications, anticoagulation used, the number of sessions, duration of hospitalization, ICU admission, mortality outcome, and occurrence of procedure-related complications were included.

Results: During the 24 months, 142 TPE sessions were performed for 33 registered patients (an average of 4.3 sessions/patient). The most common indications for TPE use in our registry were nephrology-related indications in 119 sessions (85%), while non-nephrology indications contributed for 21 sessions (15%). Among Nephrology related Indications, Thrombotic Thrombocytopenic purpura was the most common indication (47.8%), followed by post kidney transplantation (21%), while non-Nephrology-related indications were mainly for pancreatitis with Hypertriglyceridemia (9.2%). Complications arose in 2 sessions (1.4%), and mortality occurred in one (3%) critically ill patient related to non-procedure consequences and the severity of the underlying disease.

Conclusion: Our registry data confirm the safety of therapeutic plasma exchange in a professional, well-equipped nephrology setting when used for proper evidence-based indications with a lower rate of morbidity and mortality.

C. linum mat showed high potential for the growth of some species of zoobenthos, but most of these decayed during the summer environmental criticalities of the lagoon and the partial decay of the mat.
New Pathophysiology Insight of Gut Microbiota’s Influence on Systemic Lupus Erythematosus: A Brief Review
Authors: Agustini Dewi Purwita
Published: February 2022

Systemic lupus erythematosus (SLE) is a commonly found chronic autoimmune disease that affects multiple organs and systems. According to a new study, commensal gut microbiota promotes chronic autoimmunity in SLE patients with a lower Firmicutes/Bacteroidetes ratio. It has to do with the activation of inflammatory mediators such as toll-like receptors (TLRs), NOD-like receptors, adaptive immune response, and antimicrobial peptides mucins, defensins, and immunoglobulin A production. Aside from that, a decreased Firmicutes/Bacteroidetes ratio may cause T helper cells and regulatory T cells to become activated, both of which are linked to autoimmune activation in SLE. Theoretically, the immunomodulatory influence of food components in immune system activation has been the focus of nutrition for SLE patients, but probiotics and prebiotics have also been shown to dramatically enhance gut microbiota associated to SLE.

Published: February 2022

Organizations use human resource management practices to change employee attitude in order to enhance employee performance. Disposition is a form of behaviour expressed by individual over time in different conditions. Individual dispositions include personality traits which explain one’s behaviour in different situations and are genetically determined. The aim of this study was to establish effect of employee disposition on the relationship between human resource management practices and employee performance. The research was based on ability, motivation and opportunity theory and social exchange theory Positivism research philosophy and descriptive cross-sectional survey were used. Stratified random sampling was used to study a sample of 384 National Police Service officers. primary data was collected using structured questionnaires. Data was analyzed using both descriptive and inferential statistics. The study findings showed that employee disposition mediates the relationship between human resource management practices and employee performance. The findings further revealed that positive affectivity and negative affectivity individually significantly mediates the relationship between human resource management practices and employee performance. The findings supported the argument that social exchange theory assumed that employer-employee relationship depends on the fulfilment of each party’s obligation, thus rewards must be commensurate to performance. It is concluded that firm must emphasis on employee balance between positive and negative affectivity since both of the has an impact on performance. However, more emphasis should be on positive affectivity.

Published: February 2022

In the present work, we have investigated the light scattering from a Nickel metal cylinder under normal incidence. A double approach using the Fresnel reflectance model and Lorenz-Mie approach shows that the Fresnel model cannot follow the changes in the scattering regime when the size parameter changes. Experiments show that, even for large cylinders, the Fresnel model overestimates the effects of reflection in the forward direction. The simulation using the Lorenz-Mie formalism shows that as the size parameter changes the scattering regime changes and for size parameter lower than one the distribution of light intensity tends to become uniform and, for size parameter equal or lower than 0.1 the distribution is uniform and independent on the scattering angle, with a strong polarization around 70%.
Navike, znanje i stavovi o spolnosti adolescenata Brodsko-posavske županije
Authors: Koporčić Valentina , Jovanović Željko
Published: February 2022

Cilj rada: Adolescencija je
razvojna faza tijekom koje pojedinci počinju učvršćivati osjećaj identiteta, obilježen autonomnim funkcioniranjem koje će dovesti do neovisnog života uz održavanje sigurnih veza s obitelji, vršnjacima i širom zajednicom te spolnog
sazrijevanja. Cilj je ovog rada ispitati i usporediti znanje, stavove i navike o
spolnosti adolescenata te utvrditi postoje li razlike između učenika medicinske škole i gimnazije.

Metode rada: Analiza je provedena
anonimnim anketnim upitnikom od 27 pitanja općeg karaktera te pitanjima navika,
ponašanja, znanja i stavova povezanih sa
spolnošću. U istraživanje su uključeni učenici Srednje medicinske škole i Gimnazije „Matija
Mesić” u Slavonskom Brodu u dobi od 17 do 20 godina. Sudjelovalo
je 100 učenika; od toga ukupno 72 djevojke i
28 mladića.

Rezultati: Dobiveni podaci pokazuju
da je 59 % anketiranih stupilo u spolni odnos. Tek 17 % ispitanika pokazalo je
visoku razinu znanja koje se odnosi na spolnost i prevenciju rizičnih ponašanja. Većina ispitanika (65 %) smatra da bi
besplatni kontraceptivi smanjili broj neželjenih trudnoća i spolno prenosivih bolesti, dok gotovo svi (91 %)
smatraju da je zdravstveni odgoj potreban u školama.

Zaključak: Većina ispitanika stupila je u spolne
odnose, češće oni iz medicinske škole, a najčešći je razlog prvog stupanja u spolni
odnos ljubav. Gotovo svi ispitanici upotrebljavaju kontracepciju. Znanje
ispitanika o spolnosti, posebno gimnazijalaca, na nezadovoljavajućoj je razini. Ispitanice imaju
znatno jasnije stavove protiv abortusa od muških ispitanika. Većina ispitanika želi zdravstveni odgoj u školama.
Experience of using contrast-enhanced ultrasound examination in the most common malignant neoplasms of the liver
Authors: Katrich A. N. , Polshikov S. V. , Fisenko E. P.
Published: February 2022

Aim.To study the features of contrast enhancement of malignant neoplasms of the liver in patients with and without cirrhosis (LC), to study the differences in the dynamics of contrast enhancement of liver are metastatic lesions (MTS) and hepatocellular carcinoma (HCC).

Material and methods.A retrospective analysis results 58 patients with HCC (group 1) and 51 patients with liver metastases (group 2) was carried out based on morphological data. According to the criterion for the presence of LC, group 1 was divided into two subgroups. The main method of radiological diagnostics was contrast enhancement ultrasound (CEUS).

Results.The indicators of the dynamics of the Wash-in of an ultrasound contrast agent into the HCC node and the dynamics of the drug WASH-OUT from the focus in patients with LC did not significantly differ from those in patients without cirrhosis. HCC is characterized by the onset of leaching of the ultrasound contrast agent after 62 seconds from the beginning of the study, which significantly differs from MTS (p <0.05). The parameters in predicting the G3 stage of the tumor were as follows: the parameter “onset of WASH-OUT” of the from the focus ><79 sec, the parameter “time of maximum WASH-OUT” of the ultrasound contrast agent ><270 seconds. In our opinion, certain difficulties are presented by the diagnosis of highly differentiated carcinomas due to the absence of the WASH-OUT phenomenon in 50% of patients. Differential diagnosis of metastases should be based on a combination of a number of signs, the most important of which, in our opinion, are: early onset of elution of ultrasound contrast agent, “black hole” symptom, peripheral ring-shaped enhancement in arterial phase.>

Conclusion.The data obtained with the help of CEUS confirm the effect of “arterialization of hepatic blood flow” in patients with LC. Differences in the parameters of contrasting HCC nodes in subgroups of patients with and without LC are not statistically significant. The polymorphism of the signs detected in MTS in the liver is due to the morphology of the primary tumor and the size of the neoplasms. Differential diagnosis should be based on a combination of signs of the dynamics of ultrasound contrast agents.

Mikrogramme 1924/25
Authors: Walser Robert
Published: February 2022

Mit dem ersten Band der sechsten Abteilung der Kritischen Robert Walser-Ausgabe beginnt eine neue Erschließung des mikrographischen Nachlasses von Robert Walser. Das Konvolut der «Mikrogramme» umfasst 526 lose Blätter unterschiedlichen Formats, die aus Walsers Schaffensphase von 1924 bis 1933 stammen. Ein großer Teil seines Spätwerks wurde hier entworfen, aber nur etwas mehr als die Hälfte der mikrographischen Entwürfe hat der Autor selber weiterverwertet.
Die legendären und immer wieder mystifizierten Mikrogramme, die in einer schwer zu lesenden Kleinstschrift notiert sind, werden hier erstmals vollständig faksimiliert, transkribiert und ediert. Editorische Einheit ist das nach einer vermuteten Entstehungschronologie eingeordnete einzelne Blatt (oder der entsprechende Blattverbund). Die Faksimiles in Originalgröße werden zunächst in einer Umschrift zugänglich gemacht, welche die topographischen Verhältnisse der Textverteilung auf dem Blatt anschaulich wiedergibt. In ihr wird die ursprüngliche Konstellation der Aufzeichnungen auf dem Blatt für den Leser unmittelbar sichtbar. In einem zweiten editorischen Schritt werden die verschiedenen Aufzeichnungen aus dem Blattkontext gelöst und als Einzeltexte dargeboten, welche die Entwürfe in ihrem chronologischen Textverlauf und im originalen Zeichenbestand lesbar machen. Dieser Teil der Edition wird in den Marginalien philologisch kommentiert. Die einzelnen Aufzeichnungen sind mit den edierten Reinschriften und Erstdrucken in den andern Abteilungen der Kritischen Ausgabe verknüpft.
In der komplementären elektronischen Edition liegen die Faksimiles in hochaufgelösten, d.h. stark vergrösserbaren Scans vor, die durchgehend mit den Transkriptionen verknüpft sind. Sie ermöglichen so ein tiefergehendes Text- und Handschriftenstudium. Mit der hier begonnenen Neuedition der Mikrogramme wird die konsequente Arbeitstechnik Walsers sowie seine stilistisch und poetologisch singuläre Schreibweise am konkreten Material evident. Die Edition lädt dazu ein, den Kosmos des Walserschen Spätwerks neu zu entdecken und zu erforschen
