Analisis Amplitudo Getaran Terhadap Jenis Kerusakan Unbalance, Looseness, Dan Kerusakan Bearing Pada Motor Induksi 3 Phase
Authors: Setiono Andika Mardian , Rijanto Achmad , Zulfika Dicki Nizar 
Published: May 2022

Getaran adalah gerakan yang teratur dari benda atau media dengan arah bolak-balik dari kedudukan seimbang. Aplikasi ilmu getaran telah banyak diterapkan. Diantaranya adalah untuk mengetahui jenis kerusakan pada motor induksi 3 phase dengan menganalisa besar amplitudo getarannya. Metode penelitian yang digunakan adalah dengan cara menganalisa perbandingan getaran pada saat motor induksi dalam keadaan mengalami masalah setelah penangannya. Hal ini dilakukakan dengan menempatkan sensor vibrator meter pada posisi vertikal dan horizontal terhadap sumbu pusat putaran motor, untuk mendapat nilai amplitudo yang dianalisa, lalu disimpulkan apakah jenis kerusakannya. Kerusakan motor induksi pada umumnya yaitu unbalance, kerusakan pada bearing, dan looseness. Dengan data yang diperoleh, kemudian menganalisa penanganan yang tepat dengan bahan yang sesuai, dengan harapan mampu memudahkan langkah awal yang akan diambil pada saat memperoleh kerusakan yang dipicu oleh tingginya vibrasi, sehingga dapat meredam gejolak vibrasi yang timbul, agar tidak berpengaruh pada komponen motor yang lain. Setelah dilakukan uji coba maka diperoleh hasil bahwa motor dengan kondisi unbalance bisa diredam dengan plat kuningan dengan ukuran 0,25 mm, sedangkan pada keadaan looseness bisa ditangani dengan mengeraskan ulang baut support yang longgar atau bisa diganti, dan pada keadaan bearing rusak bisa dilakukan perawatan seperti regrease.

Published: May 2022

Penelitian ini bertujuan untuk mengetahui hasil tegangan dan arus listrik yang dihasilkan PLTMH, untuk mengetahui daya maksimal yang dihasilkan PLTMH pada saat diberi pembebanan. Pada penelitian ini metode yang digunakan adalah metodologi eksperimental. Uji eksperimental ini dilakukan dengan cara mengukur setiap komponen yang digunakan dalam PLTMH yang berupa tegangan dan arus listrik yang dihasilkan. Dengan menggunakan generator Zyt-70-05, buck-boost converter, dan inverter taffware 500 watt sebagai komponennya. Maka hasil dari pengujian menggunakan beban lampu 3 watt daya yang masuk hanya 2,25 watt, kipas kecil 25 watt daya yang diterima 20,25 watt, kipas besar 50 watt daya yang diterima 29,25 watt, bor 550 watt daya yang masuk 112,29 watt. Dilihat dari grafik hasil penelitian semakin besar beban yang diterima maka tegangan yang dihasilkan inverter semakin menurun sedangkan kuat arus listrik yang mengalir semakin tinggi. Dengan hasil pencapaian ini maka dapat disimpulkan, PLTMH ini masih belum sempurna dikarenakan hanya mampu menyuplai beban yang berdaya kecil saja sehingga belum mampu untuk menggantikan listrik PLN untuk menyuplai listrik rumah.

Vingt bougies déjà pour la théorie de l’effectuation : bilan, critiques et perspectives pour la prochaine décennie
Authors: Jacquemin Amélie , Carré Nathalie , Silberzahn Philippe , Vian Dominique 
Published: May 2022

Dans cet entretien, Philippe Silberzahn et Dominique Vian, experts et praticiens de l’effectuation, dressent les contours de cette théorie : différences en termes d’approches et d’épistémologie entre effectuation et causation, mais aussi complémentarités et combinaisons de ces approches ; lignes de démarcation avec le bricolage, l’improvisation ou encore le Lean Startup. La place de l’effectuation dans l’apprentissage de l’entrepreneuriat est également abordée, de même que l’utilité, la portée des principes de l’effectuation de façon plus générale pour créer de la nouveauté ( Novelty Creation ). Philippe et Dominique reviennent enfin sur les critiques dont a fait l’objet cette théorie, évaluent leur pertinence et identifient des éléments qui mériteraient davantage d’investigations.
Retour réflexif sur l’usage des outils par des accompagnateurs expérimentés
Authors: Papastratis Yann , Girbau-Grimoin Marie-Hélène , Renard Corinne , Raveneaux Claire 
Published: May 2022

Corinne Renard, Directrice de la pépinière Eole du Grand Narbonne dans l’Aude, et Claire Raveneaux, responsable du pôle Entreprendre à la CCI du Gard, se sont prêtées au jeu de l’interview croisée sur leur pratique et leurs approches des outils d’accompagnement et de leurs évolutions. Elles ont été interrogées par Marie-Hélène Girbau-Grimoin et Yann Papastratis qui, pour le compte des CCI et CMA de la région Occitanie ont cofondé Pro’créa, le congrès national des acteurs de l’accompagnement entrepreneurial. Corinne Renard et Claire Raveneaux ont en commun, un grand professionnalisme, une longue expérience du métier d’accompagnant et la recherche permanente de la meilleure réponse aux attentes des porteurs de projets. Mais elles diffèrent dans leurs méthodes, liées aux contraintes de leurs organisations : traitement sur mesure pour un petit nombre de projets porteurs d’innovation en pépinière, et approche plus standardisée, du fait de l’important volume de créateurs reçus, en réseau consulaire. Très critiques vis-à-vis des outils qui deviennent le but au lieu de le servir, ou des supports imposés par des considérations étrangères aux besoins des créateurs, les deux praticiennes portent un regard distancié par rapport aux outils qu’elles utilisent et qui, finalement, ne sont que la matérialisation de leur process d’accompagnement.
L’entrepreneuriat étudiant : regards croisés sur les thèses primées en 2021
Authors: Fayolle Alain , Gabay-Mariani Laëtitia , Le Pontois Sandrine 
Published: May 2022

Au cœur des préoccupations des pouvoirs publics, l’entrepreneuriat mobilise d’importantes ressources et l’éducation en entrepreneuriat est évaluée sur sa capacité à produire les effets attendus : création d’entreprises, d’emplois et développement de l’esprit d’entreprendre. Le caractère processuel de la démarche entrepreneuriale, ancrée dans un écosystème par nature dynamique, induit de nécessaires interactions entre les acteurs impliqués dans le projet. Leurs subjectivités influent sur leur rapport au projet entrepreneurial. Les deux thèses présentées dans ce ‘Regards croisés’ interrogent d’une part les formes que peut prendre l’engagement de l’entrepreneur naissant dans ce contexte spécifique de création et d’émergence et d’autre part l’évaluation nécessairement multidimensionnelle de l’impact des dispositifs d’éducation en entrepreneuriat. Ces travaux contribuent à alimenter la boîte à outils des accompagnateurs en prenant en compte le rôle des facteurs contextuels.
Pro male ablatis et pro incertis
Authors: Esposito Anna 
Published: May 2022

Da un ampio dossier di fonti (testamenti, codicilli, donazioni mortis causa, etc.) relativi all’area romana, si è potuto evidenziare una tendenza non omogenea per quanto riguarda i lasciti di restituzione, nonostante la grande diffusione delle pratiche creditizie spesso usuraie, tra ‘300 e inizio ‘500. Nella documentazione trecentesca i lasciti per i male ablata sono attestati seppure non frequentemente, sostanzialmente generici (non sono mai espressi i nomi delle persone beneficiarie), di scarsa entità, mentre più significativi sono quelli legati a casi concreti, come le piccole truffe e ogni tipo di esazione indebita. Ma nel pieno e tardo ‘400 la formula della restituzione del maltolto tende a scomparire del tutto dagli atti di ultima volontà con solo poche eccezioni e per lasciti pro exoneratione conscientie, mentre aumentano i lasciti di carità a sfondo sociale, come la fondazione di ospedali e domus pauperum, la dotazione di ragazze povere, etc.
I male ablata dei lombardi fra sanzione ecclesiastica e riconoscimento pubblico nei paesi Bassi
Authors: Bordone Renato 
Published: May 2022

Il problema della restituzione dei male ablata nelle Fiandre e nei Paesi Bassi, dove assai diffusa era l’attività creditizia esercitata dai lombardi, mette in luce una ricorrente ambiguità nel comportamento delle autorità laiche o ecclesiastiche nei confronti dei prestatori che, di volta in volta, potevano essere condannati come usurai manifesti o considerati onesti mercanti ai quali legittimamente concedere l’esercizio del banco di pegno. A partire dalle decisioni del II Concilio di Lione (1274) e del successivo Concilio di Vienne (1311) – oltre che dei sinodi locali – la questione nodale era costituita appunto dalla definizione dello status di usuraio manifesto e dalle condizioni necessarie per ottenere sia la remissione della scomunica che da tale status derivava sia la successiva riammissione nella societas christiana.

Authors: Silva Laila Lorena Nogueira Batista da , Rabelo Doris Firmino 
Published: May 2022

Este estudo avaliou a associação da percepção de baixa afetividade nos relacionamentos familiares de pessoas idosas com a faixa etária, o sexo e as condições de saúde física e psicológica. Participaram 134 idosos(as) do interior da Bahia e os dados foram coletados no domicílio utilizando-se: Questionário de Informações Sociodemográficas; Questionário de doenças e sinais e sintomas autorrelatados; Índice de independência nas ABVDs; Escala de desempenho nas AIVDs; Escala de Depressão Geriátrica; Inventário de Ansiedade de Beck; Familiograma. Foram feitos os testes Qui-quadrado ou Exato de Fisher e análise de regressão logística univariada e multivariada, com critério Stepwise de seleção de variáveis (p<0,05). Os resultados mostraram maior frequência de pessoas idosas com idade entre 60 a 74 anos e com dependência nas atividades básicas de vida diária com percepção de baixa afetividade. As pessoas idosas com maior risco de relatarem baixa afetividade foram: as com idade entre 60 e 74 anos (risco 14.0 vezes maior) e as com dependência nas atividades instrumentais de vida diária (risco 4.3 vezes maior). Este estudo mostrou que a faixa etária e a capacidade funcional se apresentaram como fatores de risco para a percepção de baixa afetividade, o que pode implicar na qualidade das relações familiares.

Published: May 2022

Context:
While laparoscopy has been the standard procedure for gallstone treatment, recent advances including the use of indocyanine green (ICG) in laparoscopic cholecystectomy have made it easier to understand the biliary tree and reduce the risk of bile duct injury.

Aims:
In this retrospective study, we aim to determine the efficacy of ICG in near-infrared fluorescence cholangiography (NIRFC) for visualising biliary anatomy.

Settings and Design:
A total of 90 patients with the symptoms of cholelithiasis were enrolled for this retrospective study.

Subjects and Methods:
All the patients underwent cholecystectomy approximately 53.8 min (40–90 min) after the intravenous administration of mean volume 1.6 ml (1–2 ml) ICG. The surgeons used NIRFC along with ICG for real-time visualisation of biliary anatomy.

Results:
The mean operative time for the surgery was 65.7 min (25-120 min) with no post-surgical complications observed in the patients. The average length of stay was 2 days (1–3 days). ICG usage with NIRFC enabled identification of cystic duct, common hepatic and common bile duct, the junction between common hepatic and bile duct, right and left hepatic duct in 87.7%, 94.4%, 80% and 14.4% of cases, respectively.

Conclusions:
ICG fluorescence allowed successful visualisation of at least 1 biliary structure in 100% of cases.

Authors: Jose R. Sahaya , Kannan Visnu 
Published: May 2022

Aims:
The aim of the study is to evaluate the functional and radiological outcome of total knee replacement for osteoarthritis knee with varus deformity, using medial parapatellar approach and posterior stabilized (PS) design.

Settings and Design:
This is a prospective observational study and nonprobability sampling technique.

Materials and Methods:
In this prospective study, 20 patients with osteoarthritis knee of Grades III and IV were selected according to Kellgren-Lawrence Grading system. In this study, we assess the functional outcome of total knee replacement using Knee Society Score and radiological outcome using radiographic alignment. The patients were regularly followed up for both functional and radiological outcome at 1st, 3rd, 6th, 12th, and 18 months and then yearly.

Statistical Analysis Used:
The collected data were analyzed by SPSS 20.00 using the Chi-square test.

Results:
Preoperatively, our overall mean Knee Clinical and Knee Functional Score was 30.9 and 36.45 which improved to 87.7 and 84 postoperatively with the significant P < 0.001. Our study shows that we have 80% of excellent and 15% good results following total knee replacement. Radiologically all patients have a near-normal radiographic alignment which in turn improves the functional outcome of the patients.

Conclusion:
Total knee replacement using nonconstrained, PS design and medial parapatellar approach gives functionally excellent pain relief, increased range of motion, restoration of normal function, low prevalence of patellofemoral complications, correction of varus and fixed flexion deformities, and restoration of normal mechanical alignment. Postoperatively, patients with near-normal radiographic alignment like femorotibial angle, posterior condylar offset, and posterior tibial slope have good functional outcome and faster rehabilitation. Correct positioning of the components axially and rotationally improve both the functional and radiological outcome. However, longer follow-up is needed to determine the long-term effect of Posterior Substitute Design.

Introduction:
The purpose of this study was to evaluate the outcomes of surgical management of chondroblastoma in appendicular skeleton treated with curettage and reconstruction.

Materials and Methods:
This retrospective study included 40 patients of chondroblastoma treated with intralesional curettage and filling of defect with bone graft or bone graft substitute or bone cement. The patients were prospectively followed to consolidation of bone graft or bone graft substitute. The mean age of presentation was 14 years (13–32 years). There were 24 were male and 16 were female patients. The mean follow-up was 11 years (4–17 years).

Results:
The location of chondroblastoma was proximal tibia in 12 patients, distal femur in 14 patients, proximal femur in 8 patients, and proximal humerus in six patients. The physis was found open (8), closing (12), and closed (20) patients. The tumour was of Enneking grade of tumour was 1 in 22, II in 14 and III in 4 patients. The mean union time in bone graft group and bone graft substitute group 3 months and 4 months, respectively. There was local recurrence in six patients (3 in bone graft group and 2 in bone graft substitute group, 1 in bone cement group). The other complications were surgical site infection (two cases). The mean Musculoskeletal Tumor Society score in both groups was 27.

Conclusion:
Intralesional curettage provides excellent functional outcomes with preservation of adjacent joint mobility. The methods of reconstruction with bone graft, bone graft substitute, and bone cement provide optimal results, and the outcomes were comparable in all these groups.

Published: May 2022

Introduction:
Subtrochanteric fractures occur in a zone extending from the lesser trochanter to 5 cm distal to the lesser trochanter, however, extension into the intertrochanteric region is common. The deforming forces on both the proximal and distal segments are difficult to control due to peculiar muscle insertion to the proximal and distal fragments. This study aims to assess the effectiveness of Proximal Femoral Nailing (PFN) for the treatment of subtrochanteric fractures of femur.

Materials and Methods:
This is a prospective study of evaluation of results of 32 patients who sustained subtrochanteric femur fracture treated with PFN at our institute from June 2018 to May 2020. All the patients in this study were above 18 years of age including both genders. All closed fractures and open Grade 1 and 2 fractures according to Gustilo–Anderson classification were included.

Results:
In this study of 32 patients, the mean age was around 3rd and 4th decade of life and Road traffic accidents was the major cause of injury (high-velocity trauma). The average radiological union time was 15.9 weeks. In 2 (6.24%) patients, there was postoperative infection and 3 (9.36%) patients had broken implant and 1 (3.12%) patient had nonunion. According to Harris hip score, 29 (90.6%) patients showed excellent-to-good results.

Conclusion:
PFN is a closed intramedullary nailing procedure which achieves biological fracture fixation with minimal blood loss, preserving the fracture hematoma and thus aiding in healing of the fractures. It provides good axial as well as rotational stability.
