Koperasi di Indonesia memiliki tujuan untuk dapat meningkatkan taraf hidup masyarakat khusunya anggota koperasi. Namun, masih banyak koperasi tidak bisa berkembang bahkan berhenti beroperasi karena banyaknya persoalan yang dihadapi. Rintisan Koperasi Syariah Berkah (KSB) merupakan salah satu rintisan koperasi di desa Tanimulya Kec. Ngamprah Kab. Bandung Barat yang sedang banyak menghadapi persoalan yaitu kurangnya pengetahuan para pengurus dan anggota mengenai konsep dasar dan manajemen koperasi syariah. Melihat kondisi ini, Tim PKM Polban memandang perlu untuk memberikan pelatihan dalam peningkatan pengetahuan mengenai manajemen koperasi syariah kepada KSB. Melalui pemberdayaan ini diharapkan Rintisan KSB dapat menjadi koperasi yang dapat mensejahterakan anggotanya. Pemberdayaan KSB dilakukan melalui pemberian pelatihan konsep dasar koperasi dan manajemen koperasi syariah, serta perbaikan administrasi koperasi syariah. Metode yang digunakan yaitu penyampaian materi manajemen koperasi syariah kemudian dilakukan pendampingan untuk memastikan materi yang disampaikan dapat diaplikasikan. Dari kegiatan PKM, peserta mendapat banyak pengetahuan baru mengenai manajemen koperasi syariah. Sedangkan hasil kuesioner yang disebarkan pada peserta diperoleh tingkat kepuasan yangtinggi terhadap kegiatan PKM yang telah dilangsungkan. Selain itu, peserta juga berharap ada kegiatan lanjutan pada tahun depan yaitu manajemen usaha dan strategi bisnis untuk koperasi syariah, manajemen keuangan, manajemen pemasaran, serta perancangan aplikasi untuk koperasi syariah.

Published: November 2021

Masjid merupakan salah satu tempat untuk menyampaian pesan moral dari para penceramah, khotib, ustad, guru ngaji kepada para jamaahnya. Kualitas audio yang baik dan jelas dalam masid menjadi suatu keharusan. Ketika sistem tata suara di mesjid terganggu seperti suara tidak jelas, muncul feedback bahkan hal terburuk sampai speakernyamengalami kerusakan akan menjadi masalah bagi para jamaah untuk menerima informasi dari para penceramah. Hal ini terjadi di Masjid Luqmanul Hakim POLBAN. Delapan buah speaker dinding 60W 8Ω yang terpasang sering sekali mengalami kerusakan. Speaker tersebut dicatu oleh 2 buah Amplifier Stereo dengan total daya keluaran 480Wtiap kanal. Tidak dipasang alat Sound Compressor atau limiter mengakibatkan speaker menjadi rentan terhadap kerusakan ketika ada kenaikan daya akibat feecback atau setting volume terlalu besar. Metode yang dilakukan untuk mengatasi masalah tersebut yaitu melakukan observasi dan analisis spesifikasi dan istalasi pada peralatan soundsystem yang sudah terpasang. Ada dua opsi untuk mengatasi masalah salah instalasi sound system tersebut. Pertama speaker dipertahankan maka Amplifier diganti dengan yang memiliki daya keluaran per kanal maksimum 120W di impedansi 8Ω. Atau diganti speaker dengan yang memiliki daya total per kanal 480W. Dari ujicoba lapangan dipilih opsi 2 oleh pengelola masjid dan hanya satu Amplifier saja yang digunakan. Hasil setelah tiap kanal dipasang masing-masing 2 buah speaker 240W/8Ω secara paralel diperoleh suara yang cukup jelas tanpa distorsi dengan besar SPL rata-rata 72,9dB dan setelah dilakukan ujicoba selama 3 bulan tidak ada masalah.

Published: November 2021

Abstract
Transition-metal dichalcogenides (TMDCs), such as MoS2, lack their inversion center in monolayers, exhibiting in-plane piezoelectricity at a nanoscale thickness. In conventional piezoceramics devices, the operating mechanism has been well established that piezocharges appear at crystal edges and how these charges act in capacitor structures. Although TMDC monolayers are expected to possess a unique system due to their semiconductor nature, strong interaction with contact metals alters physical properties predominantly. In this study, we identify the position of piezocharges in MoS2 generators based on the displacement current under dynamic strain. The present results provide new insights for future device engineering.

A Sample of Massive Black Holes in Dwarf Galaxies Detected via [Fe x] Coronal Line Emission: Active Galactic Nuclei and/or Tidal Disruption Events
Authors: Molina Mallory , Reines Amy E. , Latimer Lilikoi , Baldassare Vivienne , Salehirad Sheyda 
Published: November 2021

Abstract
The massive black hole (BH) population in dwarf galaxies (M
BH ≲ 105
M
⊙) can provide strong constraints on the origin of BH seeds. However, traditional optical searches for active galactic nuclei (AGNs) only reliably detect high-accretion, relatively high-mass BHs in dwarf galaxies with low amounts of star formation, leaving a large portion of the overall BH population in dwarf galaxies relatively unexplored. Here, we present a sample of 81 dwarf galaxies (M
⋆ ≤ 3 × 109
M
⊙) with detectable [Fe x]λ6374 coronal line emission indicative of accretion onto massive BHs, only two of which were previously identified as optical AGNs. We analyze optical spectroscopy from the Sloan Digital Sky Survey and find [Fe x]λ6374 luminosities in the range L
[Fe x] ≈ 1036–1039 erg s−1, with a median value of 1.6 × 1038 erg s−1. The [Fe x]
λ6374 luminosities are generally much too high to be produced by stellar sources, including luminous Type IIn supernovae (SNe). Moreover, based on known SNe rates, we expect at most eight Type IIn SNe in our sample. That said, the [Fe x]λ6374 luminosities are consistent with accretion onto massive BHs from AGNs or tidal disruption events (TDEs). We find additional indicators of BH accretion in some cases using other emission line diagnostics, optical variability, and X-ray and radio emission (or some combination of these). However, many of the galaxies in our sample only have evidence for a massive BH based on their [Fe x]λ6374 luminosities. This work highlights the power of coronal line emission to find BHs in dwarf galaxies missed by other selection techniques and to probe the BH population in bluer, lower-mass dwarf galaxies.
Using a Neural Network Classifier to Select Galaxies with the Most Accurate Photometric Redshifts
Authors: Broussard Adam , Gawiser Eric 
Published: November 2021

Abstract
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will produce several billion photometric redshifts (photo-z's), enabling cosmological analyses to select a subset of galaxies with the most accurate photo-z. We perform initial redshift fits on Subaru Strategic Program galaxies with deep grizy photometry using Trees for Photo-Z (TPZ) before applying a custom neural network classifier (NNC) tuned to select galaxies with (z
phot − z
spec)/(1 + z
spec) < 0.10. We consider four cases of training and test sets ranging from an idealized case to using data augmentation to increase the representation of dim galaxies in the training set. Selections made using the NNC yield significant further improvements in outlier fraction and photo-z scatter (σ

z
) over those made with typical photo-z uncertainties. As an example, when selecting the best third of the galaxy sample, the NNC achieves a 35% improvement in outlier rate and a 23% improvement in σ

z
compared to using uncertainties from TPZ. For cosmology and galaxy evolution studies, this method can be tuned to retain a particular sample size or to achieve a desired photo-z accuracy; our results show that it is possible to retain more than a third of an LSST-like galaxy sample while reducing σ

z
by a factor of 2 compared to the full sample, with one-fifth as many photo-z outliers. For surveys like LSST that are not limited by shot noise, this method enables a larger number of tomographic redshift bins and hence a significant increase in the total signal to noise of galaxy angular power spectra.

La gouvernance urbaine « les pieds dans l’eau »
Authors: Boughedada Thibault 
Published: November 2021

Cette contribution analyse les interactions entre les politiques d’aménagement du foncier sur la commune de Cotonou (Bénin) – particulièrement les opérations dites de lotissement et de remembrement –, et l’exposition importante de celle-ci aux contraintes environnementales, en particulier les inondations. Adossé à un travail de terrain qui recouvre plusieurs quartiers vulnérables de la ville, à des entretiens qualitatifs avec toute une chaine d’acteurs intervenants à différentes échelles, des cabinets de géomètres et urbanistes aux différents services municipaux et ministériels liés aux politiques foncières et d’aménagement, ce travail montre que ces politiques renforcent plutôt qu’elles n’atténuent la vulnérabilité de la ville et de ses habitants face aux risques environnementaux.

De nombreuses entreprises utilisent des logiciels libres dans leurs propositions commerciales. Il existe de nombreuses études de cas sur leur modèle d’affaires. Cependant, il manque une analyse globale synthétisant et structurant les différents modèles open-sources. En nous appuyant sur le cadre des modèles économiques et la littérature en systèmes d’information, nous partons des besoins en offres libres pour caractériser et comparer des modèles économiques open-sources. Cela nous permet de discuter le lien entre captation de valeur et ressources clefs. Le modèle de l’open-source apparaît basé sur la gestion et le contrôle de la dynamique d’évolution des logiciels (« logiciel flux »), dans une industrie qui s’était habituée à vendre des produits (« logiciel stock »).

Published: November 2021

The seasonal effects on the fatty acid composition of triacylglycerol (TAG) and phospholipid (PL) in the muscle and liver of male Salmo trutta macrostigma were determined using the gas chromatographic (GC) method. The fatty acid (FA) compositions of total lipid, PL and TAG fractions were determined in muscle and liver tissues of S. trutta macrostigma. The phospholipids contained a higher proportion of 16:0 compared to the TAG in the muscle tissue of S. trutta macrostigma. Docosahexaenoic acid (22:6 ω-3) and eicosapentaenoic acid (20:5 ω-3) contents were high in both muscle and liver tissues. The total lipid contents in the muscle and liver were 1.07-2.45 and 3.00-4.64%, respectively. S. trutta macrostigma is a rich source of ω-3 and ω-6, polyunsaturated fatty acids (PUFA) with numerous benefits to human health.

Published: November 2021

Introduction: Hypertensive disorders in pregnancy are an important cause of maternal mortality in Sri Lanka. Gestational hypertension (GH)/Pre-eclampsia (PEC) and threatened miscarriage (TM) share common pathophysiological mechanisms. This study was conducted to determine the association between TM and development of GH/PEC. Methodology: A case control study was conducted at Castle Street Hospital for Women, Sri Lanka from May 2014 to May 2015. Cases consisted of patients with GH/PEC and compared with age and parity matched controls. A systematic random sampling method was used. Similar number of cases and controls were compared while each group consisted of 245 subjects. Data was obtained from medical records. Patients aged 20-35 years were included and medical disorders other than GH/PEC were excluded. Results: There were 245 subjects in each group of the study. Among the cases, 56% had GH and the rest had PEC. There were 25 patients had a history of TM in the study population. About 6.5% of cases had a history TM, while only 3.6% of controls had TM. There is also a significant risk of developing PEC in a patient who had a history of threatened miscarriage (OR 3.31, 95% CI 1.35-8.11). Moreover the patients who had a history of TM tend to develop GH or PEC early, within 20-32 weeks of gestation (OR 11.49, 95% CI 3.88-33.99). As we identified, 62% of patients who had TM developed GH/PEC early (from 20 to 32 weeks) but among the cases who had no history of TM, only 12% developed GH/PEC between 20 to 32 weeks of gestation (O.R. 20.7 (5.66 to 91.96). There is a significant risk of developing severe GH/PEC in the group of patients who had a history of TM (OR 8.59, 95% CI 2.87-25.66). Eighty one percent (81%) of the cases, who had a history of TM, developed severe and moderate GH/PEC rather than mild. But the majority (63%) of the cases, who had no history of TM, developed mild GH/PEC (O.R. 7.6 (2.00 to 42.55). Conclusions: Shared pathophysiological mechanisms of GH/PEC and TM may explain the observed association between these obstetric complications. Early onset, severe GH/PEC in cases with TM suggests temporality and a biological gradient which favors causality.
PaCO2–EtCO2 Gradient and D-dimer in the Diagnosis of Suspected Pulmonary Embolism
Authors: Khajebashi Sayed Hamed , Mottaghi Maryam , Forghani Mohsen 
Published: November 2021

Background:
The diagnosis of pulmonary embolism (PE) because of nonspecific clinical presentation remains as a challenge for emergency physicians. Arterial to end-tidal partial pressure of carbon dioxide (P(a-Et) CO2) gradient may be useful in the evaluation of PE. This aimed to define the diagnostic role of P(a-Et)CO2 gradient by sidestream capnography, as a noninvasive method, and D-dimer in patients with PE.

Materials and Methods:
Two hundred and three patients with chest pain or dyspnea who attend the hospital emergency ward were enrolled over a study period at a single academic center. PE was confirmed by multidetector computed tomography (MDCT) scans. PaCO2, EtCO2, and D-dimer were measured within 24 h of MDCT by capnograph.

Results:
The combination of P(a-Et)CO2 gradient (cutoff >9.2 ng/ml) and D-dimer (cutoff >3011 ng/ml) with sensitivity and specificity of 30.2% and 87.2% showed a significant diagnostic value in detecting PE (area under the curve = 0.577, P = 0.045) but not alone (P > 0.05).

Conclusion:
As the results show, the combination of P(a-Et)CO2 gradient and D-dimer can show an acceptable diagnostic value in detecting PE, although it suggests further research on evaluating the diagnostic value of P(a-Et)CO2 gradient and combining it with other diagnostic criteria to achieve a definite and generalizable result.
