Published: January 2021

The research objective was to empower the community through training in v cakes (vegetable cakes) to increase the knowledge and entrepreneurial attitudes of the community in Palintang Village, Bandung. The method used is quasi-experimental combined with Systemic, Holistic, Interdisciplinary, and Participatory approaches. The research design used posttest only group design (treatment by subject design). The activities carried out began with problem identification, then prioritized problems, and then an action plan was made. This action plan was used as a research intervention in the form of entrepreneurship training. The independent variable is community empowerment through vegetable cakes. The dependent variables are (a) knowledge of entrepreneurship and (b) entrepreneurial attitudes. The data obtained were analyzed descriptively by looking for the percentage change and followed by a paired t-test with a significance level of 5% to analyze the differences in people's knowledge and attitudes between before and after the training. The results of the data analysis showed that the community's knowledge and attitudes were different between the pre and post-V cakes training (p <0.05). In this case, there was an increase in knowledge by 21.18%, and entrepreneurial attitudes increased by 9.57%. Thus it can be concluded that community empowerment through v-cakes training can improve the knowledge and entrepreneurial attitudes of the community in Palintang village, Bandung.

Published: January 2021

The present study is part of a framework for researching the use of the field pea in cropping systems in order to improve its economic and environmental output. The specific aim was to investigate the effect of differently fertilised preceding winter wheat on subsequent field pea output in the same crop rotation. The field experiment was conducted in Tartu county, Estonia, in 2012–2017. Seven different cropping systems were investigated: four conventional with different treatments of mineral nitrogen fertilisers and three organic including catch crops and cattle manure treatment. The DM yield of field pea in winter wheat mineral N treatments 50–150 kg N ha-1 was 2699–2852 kg ha-1, which was 33% higher than in the organic systems. There were no significant differences (p < 0.05) in nitrogen use efficiency (NUE) and N surplus between 50–150 kg N ha-1. The first 20 kg ha-1 mineral N with P25 and K95 gave a significantly higher pea yield compared to the treatment without mineral N. The catch crops reduced agronomic NUE and increased N surplus in the organic cropping systems.

Published: January 2021

This study evaluated the effects of different lamb production systems on live weight gain (LWG), carcass quality and meat quality. Four production systems for weaned intact male lambs were examined: indoor feeding with grass silage and concentrate (group 1), grazing on cultivated pasture with (group 2) or without (group 3) concentrate, and grazing on semi-natural pasture (group 4). Live weight, carcass weight, dressing percentage, carcass conformation, fatness and pH decline were recorded at slaughter, and M. longissimus thoracis et lumborum was analysed for colour, thawing and cooking loss, pH after 24 hours and 6 days, and Warner-Bratzler shear force. LWG was strongly affected by production system, being highest for group 1 and lowest for group 4 (p<0.001). Group 4 had the lowest conformation (p=0.002) and fat scores (p<0.001). Hence, production system affected age at slaughter, live weight gain, weight at slaughter, carcass conformation and fatness scores, but caused no differences in meat quality attributes in intact male lambs.

Published: January 2021

Interest in using recycled manure solids (RMS) as a bedding material for dairy cattle is increasing, but suitable information for Nordic housing conditions is scarce. The aim of our study was to investigate the effect of RMS bedding on dairy cow welfare compared to peat bedding commonly used in Finland. We conducted a 2 × 3-month cross-over study with two groups of 24 lactating dairy cows, where first three months one group was housed with RMS-bedding and the other group with peat-bedding and then vice versa for the next three months. We followed integument alterations, cleanliness of the animals and udder health fortnightly. With RMS bedding cows had less severe integument alterations in tarsal joints (p=0.0031) and their udders were cleaner (p=0.0109) compared to peat. Somatic cell count did not differ between bedding materials, but link between RMS bedding and the small number of cases of clinical mastitis cannot be ruled out. Based on this study, RMS could provide an economical and renewable bedding source for Nordic dairy farms, with no major effects on animal welfare.

Published: January 2021

The aim of our study was to investigate the impact of carnosic acid (CA), selenate (VISe) or selenized yeast (YSe) on concentrations of fatty acids (FA), tocopherols, cholesterol and malondialdehyde in the periintestinal fat (PIF) and muscles of lambs. Male lambs were fed the control diet containing rapeseed (RO) and fish (FO) oils, the CA diet containing RO, FO and CA, the YSe-CA diet with RO, FO, CA and YSe, and the VISe-CA diet with RO, FO, CA and VISe. The experimental diets with CA, irrespective of the presence of YSe or VISe, decreased sums of saturated FA (SFA) and the thrombogenic SFA in the PIF compared to the control. The experimental diets increased the Δ9-desaturation capacity in the PIF compared to the control. The experimental diets with YSe or VISe reduced sums of long-chain polyunsaturated FA in the PIF compared to the control and CA diets. The PIF and muscles of lambs fed the VISe-CA diet were characterised by the highest hypocholesterolemic/hypercholesterolemic-FA ratio, and lower modified atherogenic index compared to the control.

Consecuencias de los trabajos de Galileo en la ciencia posterior
Authors: Rivera Juárez Juan Manuel
Published: January 2021

Galileo es una figura clave en la historia de la ciencia, por ello muchos de sus conceptos y contenidos teóricos tienen un especial significado y trascendencia. En Galileo, tal vez mejor que en ningún otro de los protagonistas de la revolución científica, puede apreciarse la dicotomía teórica del nacimiento de los nuevos y cruciales conceptos de la Física Clásica: muchas de sus opiniones y de sus conceptos son aún medievales, en tanto que otros son definitivamente modernos. Justamente esa dicotomía hace difícil apreciar el  aporte real de Galileo en la formulación de los conceptos. La mayoría de los trabajos realizados por Galileo tuvieron consecuencias para la ciencia posterior, en éste trabajo se analizarán solamente dos de estas consecuencias: las modificaciones del concepto de ímpetu, y la preparación de la primera ley del movimiento de Newton.

Published: January 2021

La ocupación humana y sus actividades productivas dan lugar a los cambios de las coberturas, que afectan los servicios ecosistémicos y específicamente los servicios de regulación hídrica. La cuenca alta del río Chinchiná, es una cuenca que ha presentado cambios en sus coberturas vegetales y este cambio afecto su sistema de regulación hídrica, a esta conclusión se llegó realizando el análisis multitemporal de las coberturas y el análisis hidrológico a través de la construcción de las curvas de duración de caudales para los años con información geoespacial. Entre los resultados se encontró que, por sus condiciones iniciales en las características del suelo y las coberturas vegetales, la cuenca alta del río Chinchiná no tiene una buena capacidad de regulación de la escorrentía superficial, echo que se agrava por las dinámicas de expansión de las coberturas herbáceas y de pastos durante los años del estudio. El conocimiento de la relación entre los cambios de coberturas y la regulación de la escorrentía superficial, permite proyectar el uso adecuado de la tierra con el propósito de no afectar aún más la capacidad de regulación de la escorrentía superficial que sirve como fundamento de la biodiversidad, abastecimiento de la ciudad de Manizales.

Published: January 2021

Introduction: Previous studies were reported that osteoporosis and bone fracture occurs more frequently among Multiple sclerosis patients than the general population. The aim of this study to investigate the effects of total doses of short-term, high dose corticosteroids on bone mineral density and other affecting factors for bone mineral density in Relapsing-remitting type Multiple Sclerosis patients. Material and methods: Fifty-four patients (37 females, 17 males) with relapsing-remitting type Multiple Sclerosis who filled the diagnostic criteria according to McDonald criteria were included in the study. Femoral and lumbar bone mineral density were measured using dual energy X-ray absorptiometry. Expanded Disability Status Scale, disease duration, number of attacks, cumulative corticosteroid dose were recorded. Serum calcium, potassium, phosphorus, vitamin D, parathormone and osteocalcin levels were measured. Patients were divided into two groups: patients who have received at least 20 g intravenous metilprednisolone (Group I) and patients who have received less than 20 g intravenous metilprednisolone (Group II). We analysed association between cumulative corticosteroid dose and each parameters. Results: Osteopenia was present in 46.2% and osteoporosis in 5.5% of the study population according to femoral neck bone mineral density. Femoral bone mineral density was significantly lower among patients. There was no correlation between cumulative dose of corticosteroid and bone mineral density. Conclusion: Low bone mineral density and osteoporosis are common in Multiple sclerosis patients. High-dose steroid therapy is not be the primary cause of osteoporosis in patients with multiple sclerosis.

Published: January 2021

Objective: In this study, we aim to share the data of patients who were followed up and treated with a diagnosis of juvenile myoclonic epilepsy (JME), and to draw attention to the difficulties in diagnosis and the problems that may occur in treatment. Method: In this study, seizure types, demographic and EEG characteristics of 75 patients with JME were retrospectively analyzed in our tertiary care center. Results: Of the total 75 cases, 48 patients (64%) were female and 27 patients (36%) were male. The overall female/male ratio was 1.7/1. The age of onset of seizures ranged from 6 to 24 years old. According to seizure types, all patients had myoclonic seizures, 65 patients (86%) had generalized tonic-clonic seizures and 17 patients (22.6%) had absence seizures. Of the cases, 13 patients (17.3%) had febrile convulsions, 4 patients (5.3%) had a history of febrile convulsions in their families and 10 patients (13.3%) had a family history of epilepsy. For 63 (84%) patients, seizures were under control with valproic acid alone. When the patients EEGs were examined, 55 patients (73.3%) had generalized epileptiform activity, 11 patients (14.7%) had focal abnormaly and 9 patients (12%) had no abnormality. It was determined that the diagnosis of JME was not established at the onset of the disease and the seizures were not under control for 40% of the patients who were admitted to our outpatient clinic from different centers. Conclusion: Physicians should be very careful in the diagnosis of JME and the presence of myoclonia and absence seizures should be questioned in all patients presenting with generalized tonic-clonic seizures between 8-20 years of age in polyclinic practice.

Authors: Surek Ahmet , Gemici Eyup , Bozkurt Abdussamet , Karabulut Mehmet
Published: January 2021

Objective: Endoscopic treatment is an effective and successful treatment for non-variceal upper gastrointestinal system (GIS) bleedings. In recent years, endoscopic combined therapies have been recommended for hemostasis. The aim of this study was to investigate primary hemostasis rates and re-bleeding rates obtained by epinephrine injection alone. Material and Methods: We analysed patients who had alone endoscopic epinephrine injection treatment for upper gastrointestinal system bleeding between January 2014 and January 2019. Gender, age, etiology of bleeding, Forrest classification, treatment efficacy and re-bleeding rates of the patients were recorded. The files of the patients were analyzed retrospectively. Results: The number of patients who met the study criteria was 107. There were 16 patients in Group 1 (Forrest 1a), 64 patients in Group 2 (Forrest 1b) and 27 patients in Group 3 (Forrest 2a). Primary hemostasis was achieved in 14 (87.5%) of 16 patients in Group 1, 62 (97%) of 64 in Group 2, and 27 (100%) of 27 Group 3. Re-bleeding rates were 4 (28%), 10 (16%), 2 (7%) in groups 1,2 and 3, respectively. Conclusion: It is thought that endoscopic combined treatment should be applied especially in patients with Forrest 1a and 1b bleeding ulcers, whereas in Forrest 2a ulcer patients, because of both the high rate of primary hemostasis and low rate of re-bleeding according to the results of the present study, the treatment of adrenalin injection alone can be used alone like other hemostasis modalities
Renal, pelvic and mesenteric tumors with low signal intensity on T2-weighted MR image: A review
Authors: Mohammad Dhulaimi , Moroj Aldarmasi
Published: January 2021

The magnetic resonance (MR) imaging of intra-abdominal tumors is necessary for clinical practice. MR imaging involves the optimal evaluation of masses due to its inherent soft-tissue contrast and multiplanar scanning abilities. T2 low-signal tumors are not common, and individuals need to be careful when interpreting them. The tumors that contain smooth muscle components, a high nucleus-to-cytoplasm ratio, or papillary architecture, among other components, tend to display low signal intensity on T2-weighted images. MR imaging allows for both the detection and characterization of tumors, especially when they have low signal intensity when presented on T2-weighted images. As a result, it becomes essential to identify the various characteristics that define each tumor. Identification of the tumor spectrum and knowing the cause of low signal intensity on T2 -weighted images helps the radiologist to narrow the differential diagnosis and reach a final diagnosis.

Authors: Arslanagic Selma , Karamehic Jasenko
Published: January 2021

Introduction: Burn, depending on the degree of severity and depth, induces significant pathophysiological response of the body. Our study is the prospective study for assessment of T lymphocyte immunological changes in patients with burns, with different degrees of %TBSA and depth of burns. Research objectives: Objectives of this study were to assess %CD3+Ly, %CD4+Ly, %CD8+Ly, %CD3+ HLA-DR+Ly, %CD4+Ly /CD8+Ly), of burned body with different %TBSA degrees, different depth burns and to establish predictive value of immune suppression these parameters. Patients and methods: According to %TBSA, patients were classified into three groups: mild burns with TBSA% < 15% (30 patients), group of medium burns with %TBSA from 15%-25% (30 patients) and group with %TBSA > 25% to 40% (30 patients). According to the depth of burns, patients were classified into two groups, partial-thickness burns, (39 patients), and full-thickness burns (51 patients). We followed laboratory parameters: % CD3+Ly, % CD3+ CD4+Ly, % CD3+CD8+Ly, % CD3+HLA-DR+Ly, CD4 / CD8 (%) lymphocytes (on day 7th and on day 14th). Results: Percentage of CD3+ lymphocytes was significantly lower in severe burns compared to the moderate-heavy burns and significantly lower compared to the mild burns. Percentage of CD3+CD4+ lymphocytes was significantly lower in severe burns compared to moderate-heavy burns and in relation to mild burns (results on day 14th); also are lower in moderate-severe burn compared to mild burns. On day 14th, the% CD4 / CD8 ratio was not significantly lower in the severe burns versus the moderate burns. On day 14th, the % CD4 / CD8 ratio was significantly lower in severe burns compared to mild burns; significantly lower in moderate burns compared to mild burns. % CD3+HLA -DR + cells was significantly lower in severe burn and moderately severe burns compared to the mild burns on day 7th, and also on day 14th. Full-thickness burns have significantly lower %CD3+lymphocytes, %CD3 +CD4+ lymphocytes, %CD3+HLA-DR+ lymphocytes, ratio of % CD4/CD8 lymphocytes compared to partial-thickness burns. Conclusions: Peripheral blood T lymphocytes are one of the key indicators of immunosuppression of patients with burns of different % TBSA and different degrees of burn depth. Larger %TBSA and full-thickness burns injected stronger systemic immunosuppression, compared to smaller %TBSA and partial-thickness burns
Emergency abdominal ultrasound as sufficient diagnostic modality in the diagnosis of biliary ileus
Authors: Mitrović Milica , Stanišić Nevena , Perišić Zlatko , Lešević Ivana , Vasin Dragan , Doklestić Kristina
Published: January 2021

Introduction: Biliary ileus is a rare emergency condition that mainly affects the elderly population, with a predominance of females and a mortality rate of 12-27%. It is a mechanical intestinal obstruction caused by the impaction of the biliary calculus within the gastrointestinal tract. It occurs due to the formation of bilio-enteric fistula, as a rare complication of cholelithiasis. Case report: A 73-year-old male patient with epigastric pain, nausea and vomiting was referred for ultrasound exam. The analysis of the clinical-biochemical status of the patient as well as the ultrasound examination of the abdomen itself raised the suspicion of small intestine obstruction, due to the enclaved biliary calculus. After an urgent exploratory laparotomy, the diagnosis was confirmed, and enterotomy was successfully performed with calculus extraction. Cholecysto-duodenal fistula has been confirmed as a major cause of biliary ileus. The post-operative course was uneventful. Conclusion: This case report highlights the enormous importance of ultrasound diagnostics in diagnosing biliary ileus using the criteria of The Rigler Triad, which includes pneumobilia, intestinal obstruction and ectopic calculus. Initially unrecognised cause of obstruction and a late diagnosis correlated with bad prognosis. Ultrasonographic examination of these patients can be a sufficient diagnostic modality in making an accurate diagnosis and further surgical treatment of these patients

Joaquín Frenguelli formó parte en 1923 de una expedición a la Región del Iberá, organizada en el marco de un proyecto nacional, conocido como Proyecto Mollard. Los pormenores del viaje fueron documentados en publicaciones, aportando descripciones técnicas y paisajísticas precisas de las localidades, especialmente de aquellas donde se recolectaron muestras. Una colaboración entre el Museo de La Plata y la Universidad de Colorado (EE.UU.), vinculada a estudiar la flora de diatomeas de agua dulce de Argentina, permitió que en mayo de 2019 se organizara una campaña a esta región, casi 100 años después de la expedición de Frenguelli, posibilitando así la experiencia única de repetir su itinerario. El objetivo principal de este trabajo fue ubicar las localidades originales visitadas por Frenguelli mediante el empleo de tecnologías modernas, tales como imágenes satelitales y sistemas de información geográfica, a fin de colectar en ellas nuevos materiales que servirán para evaluar los cambios ocurridos en los 97 años que median entre ambas expediciones. Para ello, se digitalizó una carta esquemática publicada en 1924 sobre la base de las descripciones en la bibliografía, se georreferenciaron de manera aproximada las localidades visitadas por Frenguelli, ajustando su ubicación a campo mediante la interpretación de las descripciones de los parajes dadas por el autor y, además, se tomaron muestras en los mismos sitios, con registro de sus coordenadas geográficas con GPS. Finalmente, se obtuvieron y procesaron imágenes satelitales cercanas a la fecha de la campaña, a fin de analizar la cobertura vegetal y uso de la tierra actual en toda el área de estudio. El análisis comparativo de todos estos materiales permitió establecer que, si bien grandes áreas se conservan en estado natural, en otras áreas de la región hubo grandes cambios vinculados con la expansión de las áreas urbanas, la disponibilidad de caminos y rutas y, principalmente, cambios significativos en el uso del suelo relacionados mayormente con la forestación.  Los resultados obtenidos constituyen, en su conjunto, información de base, muy escasa hasta el presente, para llevar a cabo futuros estudios ambientales en la región.

Authors: Punta Gabriel Emilio , Domínguez Noelia , Muñoz Marina
Published: January 2021

La distribución reproductiva de la Guayata O. melanopterus, comprende áreas cordilleranas desde Perú hasta Argentina y Chile, localizadas a altitudes de más de 3000 msnm. Durante la época no reproductiva una parte de su población migra hacia regiones más bajas (de menos de 2000 msnm), al menos en la parte sur de su distribución. En Argentina su estatus de conservación se ha establecido en la categoría de vulnerable por el aumento de las interacciones con actividades humanas extractivas. Durante julio de 2016 estimamos el tamaño poblacional, describimos el uso de los ambientes y la dieta de la Guayata que pasa la invernada en el valle de Calingasta, provincia de San Juan, Argentina. Contamos un máximo de 894 individuos (rango 2-390), notando que una alta proporción de las bandadas estuvo compuesta por dos ejemplares (35,7%). La población para el valle de Calingasta se estimó en 3500 (± 2000) individuos. La Guayata se asoció en forma significativa con los ambientes del valle que presentaron pasturas cultivadas, de baja altura y próximos al agua. Su dieta resultó exclusivamente herbívora, compuesta sólo por siete especies de plantas, pertenecientes a dos grupos principales: dicotiledóneas (70,7%) y gramíneas (22,6%). Las especies más representadas fueron las leguminosas, trébol blanco Trifolium repens y alfalfa Medicago sativa (44,3% y 26,1%, respectivamente) seguida por una gramínea, la avena Avena sativa (16,0%), todas de importancia para la agricultura local. Dado su estado de conservación vulnerable el posible conflicto con la agricultura requiere de atención para mejorar la protección de la Guayata en el valle de Calingasta.

Epistemicide: the Roman Case
Authors: Peralta Dan-el Padilla
Published: January 2021

The desire to recover and preserve the antiquity that in some circles is designated as “classical” is rooted in the conviction that knowledge of that antiquity is a good. But does (or should) awareness of the epistemicides that define Greco-Roman antiquity modify the texture of that desire? Relying on the definition of epistemicide proposed by the postcolonial theorist Boaventura de Sousa Santos, this article argues that the Roman Republic and Empire engineered a staggering loss of epistemic diversity throughout the ancient Mediterranean, traceable along multiple vectors — from mass enslavement to ecological upheaval. It concludes with a summons to come to terms with the scope of ancient Rome’s epistemicide, and to embrace the epistemological and ethical recalibration needed to write its history.
Passioni proibite. Alcuni personaggi ‘scandalosi’ di Euripide di fronte al proprio Eros
Authors: Medda Enrico
Published: January 2021

Nella prima fase della sua produzione artistica, Euripide ha esplorato in numerosi drammi sopravvissuti solo frammentariamente il tema dell’eros, portando in scena personaggi femminili che parlano apertamente della propria passione amorosa e che probabilmente suscitarono scandalo in una parte del pubblico ateniese. In questo lavoro ci si sofferma sul modo in cui Euripide da una parte costruisce, con continue variazioni, il rapporto fra queste donne e le loro pulsioni, dall’altra mette in scena le conseguenze che le manifestazioni estreme dell’eros comportano per gli altri personaggi coinvolti nelle vicende. Con figure come Stenebea, le due Fedre e Pasifae, in particolare, il poeta esplora tutte le possibili sfumature del rapporto fra un personaggio femminile e il proprio desiderio, nelle forme della sintonia, dell’opposizione, e dello straniamento. Al di là del giudizio morale, il poeta costruisce vicende drammatiche nelle quali un essere umano, sotto la pressione di un condizionamento esterno di origine divina, può giungere a comportamenti autodistruttivi; d’altra parte, l’eccezionalità di questi caratteri femminili riesce, attraverso una serie di procedimenti, a mettere in crisi le strutture tradizionali di una cultura centrata sulla prospettiva maschile.

CLASSIFICATION OF SOME SPECIAL GENERALIZED DERIVATIONS
Authors: IDRISSI M. A. , OUKHTITE L.
Published: January 2021

The purpose of the present paper is to classify generalized derivations satisfying more specific algebraic identities in a prime ring with

involution of the second kind. Some well-known results

characterizing commutativity of prime rings by derivations have

been generalized by using generalized derivation.
$\mathcal{L}$-STABLE RINGS
Authors: HOROUB Ayman M. A. , NICHOLSON W. K.
Published: January 2021

If $\mathcal{L}(R)$ is a set of left ideals defined in

any ring $R,$ we say that $R$ is $\mathcal{L}$-stable if it has stable range

1 relative to the set $\mathcal{L}(R)$. We explore $\mathcal{L}$-stability

in general, characterize when it passes to related classes of rings, and

explore which classes of rings are $\mathcal{L}$-stable for some$\mathcal{\ L}.$ Some well known examples of $\mathcal{L}$-stable rings are presented,

and we show that the Dedekind finite rings are $\mathcal{L}$-stable for a

suitable $\mathcal{L}$.
J-IDEALS OF COMMUTATIVE RINGS
Authors: KHASHAN Hani A. , BANI-ATA Amal B.
Published: January 2021

Let $R$ be a commutative ring with identity and $N(R)$ and

$J\left(R\right)$ denote the nilradical and the Jacobson radical

of $R$, respectively. A proper ideal $I$ of $R$ is called an

n-ideal if for every $a,b\in R$, whenever $ab\in I$\ and $a\notin

N(R)$, then $b\in I$. In this paper, we introduce and study

J-ideals as a new generalization of n-ideals in commutative rings.

A proper ideal $I$\ of $R$\ is called a J-ideal if whenever $ab\in

I$\ with $a\notin J\left(R\right) $, then $b\in I$\ for every

$a,b\in R$. We study many properties and examples of such class of

ideals. Moreover, we investigate its relation with some other

classes of ideals such as r-ideals, prime, primary and maximal

ideals. Finally, we, more generally, define and study J-submodules

of an $R$-modules $M$. We clarify some of their properties

especially in the case of multiplication modules.
TENSOR-CLOSED OBJECTS IN THE BGG CATEGORY OF A QUANTIZED SEMISIMPLE LIE ALGEBRA
Authors: WEI Zhaoting
Published: January 2021

We consider the BGG category $\O$ of a quantized universal enveloping algebra $U_q(\mathfrak{g})$. We call a module $M\in \O$ tensor-closed if $M\otimes N\in\O$ for any $N\in \O$. In this paper we prove that $M\in \O$ is tensor-closed if and only if $M$ is finite dimensional. The method used in this paper applies to the unquantized case as well.
ON UNITARY SUBGROUPS OF GROUP ALGEBRAS
Authors: BALOGH Zsolt Adam
Published: January 2021

Let $FG$ be the group algebra of a finite $p$-group $G$ over a

finite field $F$ of characteristic $p$ and let $*$ be the

classical involution of $FG$. The $*$-unitary subgroup of $FG$,

denoted by $V_*(FG)$, is defined to be the set of all normalized

units $u$ satisfying the property $u^*=u^{-1}$. In this paper we

give a recursive method how to compute the order of the

$*$-unitary subgroup for certain non-commutative group algebras.

A variant of the modular isomorphism question of group algebras is

also considered.
A GENERALIZATION OF THE ESSENTIAL GRAPH FOR MODULES OVER COMMUTATIVE RINGS
Authors: SOHEILNIA F. , PAYROVI Sh. , BEHTOEI A.
Published: January 2021

Let $R$ be a commutative ring with nonzero identity and let $M$ be a unitary $R$-module.
The essential graph of $M$, denoted by $EG(M)$ is a simple undirected graph
whose vertex set is $Z(M)\setminus {\rm Ann}_R(M)$ and
two distinct vertices $x$ and $y$ are adjacent if and only if ${\rm Ann}_{M}(xy)$ is an
essential submodule of $M$.
Let $r({\rm Ann}_R(M))\not={\rm Ann}_R(M)$.
It is shown that $EG(M)$ is a connected graph with
${\rm diam}(EG(M))\leq 2$.
Whenever $M$ is Noetherian, it is shown that
$EG(M)$ is a complete graph if and only if either
$Z(M)=r({\rm Ann}_R(M))$ or $EG(M)=K_{2}$ and
${\rm diam}(EG(M))= 2$ if and only if there are
$x, y\in Z(M)\setminus {\rm Ann}_R(M)$ and $\frak p\in{\rm Ass}_R(M)$ such that
$xy\not \in \frak p$. Moreover, it is proved that ${\rm gr}(EG(M))\in \{3, \infty\}$.
Furthermore, for a Noetherian module $M$ with
$r({\rm Ann}_R(M))={\rm Ann}_R(M)$ it is proved that $|{\rm Ass}_R(M)|=2$
if and only if $EG(M)$ is a complete bipartite graph that is not a star.
Oral Contract on the Sale and Purchase Transactions in the Traditional Market of Palangka Raya City
Authors: Muzalifah Muzalifah , Sodiqin Ali
Published: January 2021

The application of an oral contract in buying and selling transactions in Palangka Raya City is a form of contract adopted from Banjar culture. Even traditional market players in Palangka Raya City, in particular, interpret the oral contract as something that is very principle, so that they consider a contract invalid if it is not stated verbally. This article explores the question of why the oral contract in buying and selling in Palangka Raya City is still being applied and how the oral contract law is in buying and selling transactions in Palangka Raya City. This research is qualitative research with a phenomenological approach. This study found that the application of oral contracts in buying and selling transactions in Palangka Raya City originated from the habits of Banjar tribe traders who trade in Palangka Raya City. This habit, then, develops into the habit of the local community, so it becomes a necessity to be implemented. The law of the oral contract in the transaction is valid in terms of Islamic law and civil law because it fulfills the requirements and is in harmony with the contract in buying and selling and is carried out voluntarily, is based on the principle of freedom of contract. There is a balance of achievement, and has legal certainty so that it binds both parties. The existence of this oral contract shows the legitimacy of legal norms, religious norms, and customary norms.
Islamic Harmony Examplar: The Qur'an's Frame on Social Interaction with Non-Muslims
Authors: Ilham M. , Amiruddin Muhammad Majdy , Arif Arifuddin
Published: January 2021

The actual dynamic authenticity of social life often shows accusations that religion is a source of social friction, violence, or conflict. The spirit of the Koran shows an appreciative attitude, even inviting to the meeting point (common platform) of monotheism (tauhid) which is the basic teaching of the Torah, the Bible, and the Koran. This paper aims to explore the existence of non-Muslims from the perspective of the Koran, the variants, and principles of social harmony with them. This paper uses qualitative as a method and literature as an approach. From the perspective of the Koran, there are 3 variants of arranged interactions. First in trade relations, second in marital relations, and third in political relations. The three variants of interaction must be based on the principle of Ihsan (good behavior) and Adalah (fair). Implications of this research present the idea of a meeting point between religions. This meeting point is expected to eliminate the friction of exclusivity between religious communities to create harmony and peace.
Cash Waqf: Economic Solution during the Covid-19 Pandemic

Published: January 2021

The emergence of the Covid-19 pandemic in Wuhan has made economies in various parts of the world experience instability. The real form that can be seen from the Covid-19 impact on the economy today is the Termination of Employment Relationship (PHK). Many employees have been dismissed, and various companies are even threatened with bankruptcy. Other aspects affected include casual daily laborers, MSME actors, restaurant businesses, and other businesses that involve large numbers of people. The type of study was qualitative. The researcher would explore an object to find the potential that existed in the object. This study used a library research method using secondary data obtained from articles, research results, and reference books that discussed the same topic as research. Cash waqf as Islamic financial philanthropy required the strengthening during the current pandemic to assist in the establishment of a Waqf Hospital (RSW), especially for COVID-19 victims, waqf Personal Protective Equipment (PPE), waqf masks, waqf polyclinic, Waqf Isolation House (RIW) and vaccine funding. Additionally, it could help micro business actors in funding for the sustainability of their businesses affected by the pandemic. If there were beneficiaries of cash waqf (al-mauquf alaih) who were not limited to religious provisions, there would equal distribution of aid to help slow economic recovery
