Comportamiento esfuerzo-deformación del suelo: Evolución e Importancia
Authors: Chamorro-Zurita Claudia , Fernández-Lavín Alfonso
Published: July 2022

Los modelos que emplean elemento finito son ampliamente usados en la Ingeniería Geotécnica para investigar el comportamiento esfuerzo–deformación del suelo en condiciones tanto estáticas como dinámicas. En la práctica algunos modelos constitutivos no incluyen aspectos importantes como son: la no linealidad de la rigidez en el estado de esfuerzos, la anisotropía, la dependencia del endurecimiento plástico en las deformaciones volumétricas y tampoco el efecto de la historia de esfuerzos reciente. Si bien el uso de paquetes computacionales se ha popularizado en las últimas décadas, el conocimiento de los modelos constitutivos, la adecuada selección de los parámetros de entrada y la pericia del modelador juegan un papel muy importante. Este trabajo inicia con la definición de trayectorias de esfuerzo y de la teoría del estado crítico como fundamento para el desarrollo de los diferentes modelos constitutivos (de los cuales se hace un breve recuento). Además, se abordan otros temas como: la obtención en laboratorio de los parámetros mecánicos necesarios para el modelado, la influencia del modelo utilizado y el uso del retro análisis. Finalmente, se ejemplifica la importancia de la adecuada selección del modelo numérico y de los datos de entrada en la obtención de resultados a través de casos sencillos.

Published: July 2022

The existence of the Covid-19 pandemic has had a tremendous impact in all aspects, including the educational aspect. Before the pandemic, education generally is done by face-to-face learning, but after the pandemic hit, it changed to online learning. Several problems often occur during online learning education, especially for college students, such as a mobile phone that does less support for online learning activities. Hence, the author wants to build an application that has the function of helping users to choose a mobile phone which supports online learning activities. The selection decision used by the author is the Preference Selection Index method since it can determine the value for each attribute and continue with a ranking that is able to select each attribute from the best alternative from several existing alternatives, with the help of a decision support system and application of the PSI (Preference Selection Index) method. The result indicates that the highest value obtained from smartphone selection with an average price under 3 million rupiah is infinix by 90.88%. The application's output meets the purpose because it is able to provide recommendations to buyers in determining which smartphone to buy and can simplify the decision-making process to become more accurate, effective, and efficient in generating information.

Authors: Idral Amri  , Aris Aprianto Cahyono  , Bahruddin
Published: July 2022

The low density of mass and energy are the main reason for the underutilization of great potential of Empty Fruit Bunch (EFB) as a raw material of alternative and renewable fuels. The using of bintaro fruit as co-firing and treatment of torrefaction – densification processes were believed to increase the density of mass and energy of the EFB biopellet. This study aims to determine the effect of residence time, compaction pressure, and addition of bintaro fruit to the characteristics of EFB biopellet according to ISO 17225-6 standards. Biopellet manufacture was carried out two processes sequence, namely the torrefaction process and the densification process. The torrefaction process was carried out at 275oC with residence time variations 30, 45, and 60 minutes. The densification process was carried out without binder with compaction pressure variations 30, 40, and 50 bar. The addition of bintaro fruit was intended as co-firing of EFB at a ratio 70:30. The best characteristics of biopellet were obtained under conditions of 60 minutes residence time and 50 bar compaction pressures with 3.00% of moisture content, 7.90% of ash content, 8.70% of volatile content, 80.40% of fixed carbon content, 4719.59 cal/gr of heating value, and 1.28 gr/cm3 of density. Characteristics of moisture content and volatile content decreased while ash content, fixed carbon content, and heating value increased with increasing residence time. Characteristics of density increased with increasing compaction pressure. Characteristics of proximate and heating value increased while density properties of biopellet decreased with the addition of bintaro fruit as co-firing.

Viva l’Italia: Carducci, uno strano Nobel
Authors: Scarsella Alessandro
Published: July 2022

Si ricostruisce l'atmosfera che accompagnònel 1906  il conferimento del Premio Nobel per  la letteratura a Giosue Carducci, sottolinenandone l'anacronsmo e le motivazioni esplicitamente nazionalistiche e sotterraneamente antiasburgiche. Tuttavia, la ricezione novecentesca di Carducci, da Croce fino alle soglie del 1968 continuerà a ribadirne la priorità nel canone della poesia italiana moderna.
Miłosz. Północ - Południe (intuicje i fragmenty)
Authors: Olejniczak Józef
Published: July 2022

Autor „czyta” poezję Czesława Miłosza, podążając za pozostawionymi w niej włoskimi śladami. Są nimi zarówno echa udokumentowanych w biografii poety podróży do Włoch i po Włoszech, jak i tropy wywodzone z lektury włoskich pisarzy, fascynacji malarstwem, architekturą oraz ukształtowanym przez człowieka pejzażem. Wszystkie te tropy – jak się okazuje – wprowadzają w najistotniejsze motywy poezji autora Gucia zaczarowanego, a także w zasadnicze dla tej poezji elementy tradycji literackiej. Są też obrazem ewolucji poetyki Miłosza. Esej napisany jest w poetyce fragmentu, jego autor raczej dzieli się interpretacyjnymi intuicjami, niż stawia jednoznaczne konkluzje. Raczej stawia pytania o tajemnice zawarte w wierszach Miłosza, niż udziela jednoznacznych i zamykających odpowiedzi. Niejako „zaprasza” do studiowania wierszy autora Trzech zim. Te włoskie „ślady” prowadzą jednak do konkluzji o spójności dzieła poetyckiego Miłosza.
Prawiek i inne czasy Olgi Tokarczuk w perspektywie lingwistyki kulturowej i ekologicznej
Authors: Sławek Ewa
Published: July 2022

Autorka podejmuje próbę odczytania powieści Olgi Tokarczuk Prawiek i inne czasy przez pryzmat kategorii i pojęć współczesnej lingwistyki kulturowej (etnolingwistyki) i ekologicznej, takich jak  językowy obraz świata, stereotyp, mapa mentalna, leksykalny ekosystem. Analiza języka utworu za pomocą instrumentarium lingwistyki kulturowej pozwoliła na sformułowanie przekonania, że noblistka stworzyła w tym utworze historyczno-kulturowy i społeczny „portret” tej części Europy Środkowej, która nazywa się Polska prowincjonalna. Jej zdaniem obraz ten składa się pewnego systemu prawd, mitów i nierzadko fałszywych wyobrażeń. Nie podejmując sporu z zespołem obecnych w naszej kulturze i mentalności stereotypów (np. etnicznych), mitów i przeświadczeń, pisarka wskazała na siłę oddziaływania powielanych nadal klisz myślowych. Natomiast narzędzia badawcze lingwistyki ekologicznej pozwoliły dostrzec w powieści  polemikę z tradycją humanistyki antroponormatywnej i określić postawę autorki jako proekologiczną.
Copyright Education and the Role of Library Associations: Current Practices and Needed Support
Authors: Hinchliffe Lisa , None Kaylen Dwyer , Rose Jayde
Published: July 2022

The International Federation of Library Associations (IFLA)’s 2018 “Statement on Copyright Education and Copyright Literacy” highlights the need for librarians to be copyright literate and for library associations to support copyright education for library professionals. Nonetheless, while the role of library associations in supporting copyright education is foregrounded, little research has investigated the copyright initiatives of library associations. This study addresses that gap, documenting the current copyright training activities of library associations and providing recommendations for how IFLA might address copyright education needs of library workers. The research for this study took place in two phases, beginning with case studies of six library associations, followed by a multinational survey, with respondents representing 28 library associations from 25 countries. This study reveals that associations struggle to provide the full extent of copyright education resources they would like to due to a lack of funding and lack of copyright expertise among other issues. Based on survey responses, IFLA has an opportunity to directly address a global need in the library association community and overcome the barriers to developing and delivering copyright education, beginning by providing a website with basic copyright information and resources, providing training for association members on how to develop and deliver their own copyright education training, or providing guidelines on a copyright education curriculum.

Published: July 2022

This paper presents an experimental study on the encapsulation of Mahkota Dewa extracts by maltodextrin using spray drying. The bioactive compound from dried Mahkota Dewa was obtained using a subcritical water extraction process prior to a spray drying process. The effect of feed flow rate (485 to 2115 ml/h) was investigated using one-factor-at-a-time (OFAT). It was observed that the mean particle size increase varied from 3.55 to 8.38 µm when the feed flow rate increased from 485 to 2115 ml/h. Moisture content increased 4.88 to 6.83% as the feed flow rate increased from 485 to 2115 ml/h, whereas the antioxidant activity increased slightly from 90.48 to 91.65%. The findings from this study showed that decrease in feed flow rate reduces antioxidant activity, moisture content, and particle size.

Authors: Rafeeq Mohammed , Toha Siti Fauziah , Ahmad Salmiah , MOHD RAZIB MOHD ASYRAF
Published: July 2022

The amphibious robot, which has the capability of multi-mode motion, can maneuver diverse environments with high mobility and adaptability. These are employed in the area of reconnaissance, search and rescue operations, and monitoring. The existing amphibious robots have lower maneuverability over the crawling period on uneven and slope surfaces on the land. In this paper, a kinematic model of the amphibious robot based on virtual prototyping is designed for multi-mode locomotion. ADAMS (Automated dynamic analysis of mechanical systems) is a multi-body dynamic solver adopted to build the simulation model for the robot. The novel amphibious robot employs a Rockerbogie mechanism equipped with wheel paddles. The locomotion analysis on land involves straight-going and obstacle negotiation, which is simulated using ADAMS. The simulation analysis result demonstrates increased maneuverability, achieving a robot's velocity of 1.6 m/s. Normal forces on the front and rear wheels show equal load distribution, contributing more to the robot’s equilibrium over uneven terrain. The simulation result reflects the accurate kinematic characteristics of the amphibious robot and provides a theoretical basis for developing an algorithm for robot motion control and optimization. Further, this research will concentrate on the kinematic simulation maneuvering in water mode with the wheel paddle.

Pediatric Subarachnoid Hemorrhage: Rare Events with Important Implications
Authors: Dagra Abeer
Published: July 2022

Rupture of an aneurysm is the leading cause of subarachnoid hemorrhage (SAH) which results in accumulation of blood between the arachnoid and pia mater, consequently increasing intracranial pressure. This often results in life threatening conditions like herniation or clinical presentations including focal neurological deficits. In children, these events, although rare, have significant implications. Pediatric SAH is associated with better outcomes in the hospital setting and may even be prevented proactively by the recognition of potential risk factors. Specifically, better recognition of genetic predispositions, metastatic lesions, and infectious causes of aneurysms is important to understand their growth and prevent hemorrhagic events. This review highlights the causes of pediatric SAH, reviews the models of current understanding of this etiology, and discusses the current treatment schema to provide a succinct summary and highlight gaps in current knowledge. This may lead to future investigations aimed at further improving prevention strategies, patient care, and patient outcomes.

Study Design: Retrospective cohort study.Purpose: This study aimed to evaluate the relationship between C7 plumb line (C7PL) decompensation and the Scoliosis Research Society (SRS) 22-item patient questionnaire scores, including those related to self-image, preoperatively and 2 years after surgery.Overview of Literature: In the surgical treatment of adolescent idiopathic scoliosis (AIS), inferior trunk balance caused by C7PL decompensation can negatively affect patients’ quality of life. However, there are few reports in the literature that describe or clarify how postoperative trunk imbalance affects each SRS-22 domain, including self-image domain scores.Methods: A total of 120 patients with AIS who underwent posterior spinal fusion from August 2006 to March 2017 at our facility and were followed up for 2 years or more were included. Radiological parameters were measured on whole-spine anteroposterior and lateral radiographs. Revised SRS-22 (SRS-22r) values were also recorded. Coronal trunk imbalance was defined as a deviation of ≥2.0 cm between the C7PL and the central sacral vertical line. Patients with and without coronal trunk imbalance at 2 years after surgery were defined as D (+) (decompensation type) and D (-), respectively. Mean SRS-22r values, including function, pain, self-image, mental health, and subtotal were compared between the D (+) and D (-) groups. Logistic regression analysis was performed to detect the preoperative factors related to D (+) using predictors, including curve type, maximum Cobb angle, and coronal trunk imbalance.Results: At 2 years after surgery, the D (+) group had a significantly lower self-image in the domain of SRS-22r scores compared with the D (-) group. Preoperative coronal trunk imbalance was significantly related to D (+) but not to significant changes in the postoperative SRS-22 score in any of the SRS-22 domains.Conclusions: Postoperative C7PL deviation lowers the self-image in patients with AIS. Patients with preoperative coronal trunk imbalance were significantly more likely to be D (+).

Published: July 2022

Вступ. В Україні наразі малий та середній бізнес (МСБ) є основою економіки: він щороку додає приблизно 60 % доданої вартості. 2020 р. став черговим ви­про­буванням для бізнесу через пандемію COVID-19, яка змусила підпри­ємства залу­ча­тикредитні кошти. Проблема. Пандемія виявила нові виклики як для суб’єктів МСБ, так і для кредиторів щодо цифрової трансформації власних бізнес-процесів. Метою статті є визначення основних тен­денцій кредитування малого та середнього бізнесу України в період пандемії та вста­нов­лення напрямів цифрової трансформації про­цесів кредитування МСБ. Методи. В дослідженні застосовано за­гальнонаукові методи пізнання: аналізу і син­тезу, індукції, дедукції, порі­няння, системного під­ходу для виявлення особливостей цифрової трансформації кредитування, а також ана­літико-статистичні методи для обґрун­ту­вання кредитування МСБ в період пандемії. Результати дослідження. Дослідження вия­вило зростання частки кредитування суб’єк­тів МСБ за винятком мікропідприємництва в умовах пандемії. Встановлено, що така тен­денція обу­мовлена зниженням процентних ставок за креди­тами (крім суб’єктів мікропідприємництва, які харак­теризуються як найбільш ризи­кові). В умо­вах пандемії кредитування зазнало знач­них циф­рових трансформацій (онлайн-заявки, спрощена процедура прийняття рішень, мобільні додатки, цифрові альянси). Висновки. Загалом динаміка креди­тування МСБ України в умовах пандемії свідчить про їх готовність до використання позикових кош­тів під час кризи. Пандемія стала ру­шій­ною силою цифрової трансформації кре­ди­тування МСБ з інноваційними підходами до надання послуг, обслуговування клієнтів, кон­салтингу, програмного забезпечення, ці­льових кредит­них продуктів і відносин у цифрових альянсах.

Augmented reality–assisted microsurgical resection of brain arteriovenous malformations: illustrative case
Authors: Scherschinski Lea , McNeill Ian T. , Schlachter Leslie , Shuman William H. , Oemke Holly , Yaeger Kurt A. , Bederson Joshua B.
Published: July 2022

BACKGROUND

Arteriovenous malformations (AVMs) of the brain are vessel conglomerates of feeding arteries and draining veins that carry a risk of spontaneous and intraoperative rupture. Augmented reality (AR)-assisted neuronavigation permits continuous, real-time, updated visualization of navigation information through a heads-up display, thereby potentially improving the safety of surgical resection of AVMs.

OBSERVATIONS

The authors report a case of a 37-year-old female presenting with a 2-year history of recurrent falls due to intermittent right-sided weakness and increasing clumsiness in the right upper extremity. Magnetic resonance imaging, magnetic resonance angiography, and cerebral angiography of the brain revealed a left parietal Spetzler-Martin grade III AVM. After endovascular embolization of the AVM, microsurgical resection using an AR-assisted neuronavigation system was performed. Postoperative angiography confirmed complete obliteration of arteriovenous shunting. The postsurgical course was unremarkable, and the patient remains in excellent health.

LESSONS

Our case describes the operative setup and intraoperative employment of AR-assisted neuronavigation for AVM resection. Application of this technology may improve workflow and enhance patient safety.
Compressive optic neuropathy caused by a flow-diverter-occluded-but-still-growing supraclinoid internal carotid aneurysm: illustrative case
Authors: Tsuei Yuang-Seng , Fu Yun-Yen , Chen Wen-Hsien , Cheng Wen-Yu , Liao Chih-Hsiang , Shen Chiung-Chyi
Published: July 2022

BACKGROUND

Flow diverter stenting is an effective treatment for large proximal internal carotid artery (ICA) aneurysms. Cranial neuropathy caused by the mass effect of the aneurysm usually subsides over time. However, a new onset of compressive optic neuropathy after successful flow diverter stenting of a large proximal ICA aneurysm is seldom reported.

OBSERVATIONS

A 57-year-old woman had a right supraclinoid ICA aneurysm (approximately 17 mm) on magnetic resonance angiography (MRA) in a health checkup. She received intervention with the Pipeline embolization device. Six months later, she started to experience progressive hemianopia in the left half of the visual field. Nine months after stenting, MRA showed that the aneurysm was growing and causing mass effect, but digital subtraction angiography confirmed that the aneurysm was completely excluded from the circulation. She received a craniotomy for microsurgical decompression of the optic nerve and coagulation shrinkage of the aneurysm. Clipping and thrombectomy were not attempted. Her visual fields recovered gradually. Follow-up MRA showed that the aneurysm also diminished in size.

LESSONS

Whether the coagulation technique of the flow-diverter-occluded aneurysm alone is enough to cause satisfactory shrinkage and interaction between the flow diverter and the aneurysmal vasa vasorum/neointima formation should be further examined.
Endoscopic endonasal approaches for reconstruction of traumatic anterior skull base fractures and associated cerebrospinal fistulas: patient series
Authors: Sheth Megha K. , Strickland Ben A. , Chung Lawrance K. , Briggs Robert G. , Weiss Martin , Wrobel Bozena , Zada Gabriel
Published: July 2022

BACKGROUND

Post-traumatic cerebrospinal fluid (CSF) leaks of the anterior skull base may arise after traumatic brain injury (TBI). Onset of CSF rhinorrhea may be delayed after TBI and without prompt treatment may result in debilitating consequences. Operative repair of CSF leaks caused by anterior skull base fractures may be performed via open craniotomy or endoscopic endonasal approaches (EEAs). The authors’ objective was to review their institutional experience after EEA for repair of TBI-related anterior skull base defects and CSF leaks.

OBSERVATIONS

A retrospective review of prospectively collected data from a major level 1 trauma center was performed to identify patients with TBI who developed CSF rhinorrhea. Persistent or refractory post-traumatic CSF leaks and anterior skull base defects were repaired via EEA in four patients. Intrathecal fluorescein was administered before EEA in three patients (75%) to help aid identification of the fistula site(s). CSF leaks were eventually repaired in all patients, though one reoperation was required. During a mean follow-up of 8.75 months, there were no instances of recurrent CSF leakage.

LESSONS

Refractory, traumatic CSF leaks may be effectively repaired via EEA using a multilayer approach and nasoseptal flap reconstruction, thereby potentially obviating the need for additional craniotomy in the post-TBI setting.
Primary spinal infections in patients with solid organ transplant: a systematic literature review and illustrative case
Authors: Hatter Matthew J. , Beyer Ryan S. , Camino-Willhuber Gaston , Franklin Austin , Brown Nolan J. , Hashmi Sohaib , Oh Michael , Bhatia Nitin , Lee Yu-Po
Published: July 2022

BACKGROUND

Primary spinal infections (PSIs) are a group of uncommon but serious infectious diseases considered more prevalent and aggressive among patients with chronic immunocompromised states. Association of PSI and solid organ transplant has not been systematically analyzed. The authors performed a systematic review analyzing clinical presentation and mortality of patients with PSI in the setting of solid organ transplant.

OBSERVATIONS

PSIs in patients with immunosuppressive therapy, such as those with solid organ transplant, may behave differently in terms of epidemiology, clinical presentation, and outcomes compared with nonimmunosuppressed patients. Overall PSI in solid organ transplant patients is associated with a high rate of neurological compromise, postoperative complications, and mortality.

LESSONS

Accurate diagnosis and appropriate treatment of PSI require a multidisciplinary effort. Localized pain is the most frequently reported symptom associated with PSI. As opposed to PSI in patients without transplant, inflammatory and infectious markers such as white blood cells and C-reactive protein are often not elevated. Furthermore, the causative microorganism profile varies significantly when compared to pyogenic spinal infection in patients without transplant. Aspergillus species was responsible for spondylodiscitis in transplant patients in more than 50% of cases, and the incidence of Aspergillus infection is projected to rise in the coming years.
Nonconvulsive status epilepticus due to pneumocephalus after suprasellar arachnoid cyst fenestration with transsphenoidal surgery: illustrative case
Authors: Kagami Yohei , Saito Ryu , Kawataki Tomoyuki , Ogiwara Masakazu , Hanihara Mitsuto , Kazama Hirofumi , Kinouchi Hiroyuki
Published: July 2022

BACKGROUND

Nonconvulsive status epilepticus (NCSE) requires prompt diagnosis and treatment, particularly after neurosurgical procedures for cerebral damage. Here, the authors reported an extremely rare case of suprasellar arachnoid cyst presenting with NCSE after cyst fenestration with transsphenoidal surgery, which was associated with pneumocephalus.

OBSERVATIONS

A 61-year-old man presented with visual impairment and was diagnosed with a suprasellar arachnoid cyst on magnetic resonance imaging (MRI). The patient received cyst fenestration with endonasal transsphenoidal surgery. His visual symptoms improved immediately after the operation; however, on postoperative day 3, semicoma appeared and was prolonged. The patient was diagnosed with NCSE due to pneumocephalus based on MRI and electroencephalography (EEG) findings. The administration of antiepileptic drugs (AEDs) improved his clinical symptoms and the abnormal findings on MRI and EEG.

LESSONS

This is the first case of NCSE with pneumocephalus after transsphenoidal surgery for a suprasellar arachnoid cyst. Pneumocephalus due to cerebrospinal fluid leakage can cause NCSE. Arterial spin labeling perfusion imaging and diffusion-weighted imaging are as useful for differentially diagnosing NCSE as EEG and AED tests.
Je Tsongkhapa’s Hagiographies as a Separate Field in Buddhist Historical Literature: the Early Period
Authors: Tushinov Bair
Published: July 2022

This paper examines the early period of the historical genesis of the famous Namtars of one of the most iconic figures of Tibetan Buddhism: Je Tsongkhapa Losang Drakpa (1357-1419) — the founder of the Gelug school. Hagiographic Namtars hold a special niche in Tibetan literature as records of the spiritual life of the great Buddhist figures similar to Christian Vitas. If one is to examine the literary stratum of Tibetan biographies, Tsongkhapa’s biographies are notable for being especially prolific and varied. The purpose of this study is to provide proof that Je Tsongkhapa’s biographies can serve as a field of study unto themselves. This study’s objectives preliminary has to do with examining the primary early Namtars of Tsongkhapa, the origin behind the historical source, its contents, and its author. The subject of the study are Tsongkhapa’s biographies written in Tibetan language available in the archives of the Centre of Oriental Manuscripts and Xylographs of the Institute for Mongolian, Buddhist and Tibetan Studies, as well as the archives of the TBRC. Early Tsongkhapa Namtars stand out as being particularly significant and being of great scientific interest. The novelty of this study is that it fills the various gaps that can be found in the field of Je Tsongkhapa’s biography in Russian Eastern Studies which could help with shedding light on the history of origin and proliferation of the Gelug which is particularly prevalent in Russia. The results of the study are to identify seven early namtars: two lifetime and five posthumous.

The purpose of the trial was to use the mobile nylon bag technique to determine the crude protein digestibility and calculate the digestible protein yield of soybean varieties cultivated in Hungary. The trial was carried out with 10, double cannulated (duodenal- and PVTC-cannula) hybrid barrows with initial live weights of 40±3.5 kg. The experimental basal diets were formulated on a corn-wheat-barley-soybean basis according to the requierement of growing pigs (Tybirk, 2015). A total of 20 soybean varieties were tested in this experiment. After simulating gastric digestion the nylon bags were inserted into the duodenum of ten barrows through simple duodenal T-cannulae. Ten bags were administered to each pig daily. A total of 200 (10 samples/soybean variety) bags were inserted over a 4-day period. The mean, standard deviation, minimum and maximum values of the crude protein digestibility of soybean samples were calculated. The protein yields per hectare according to the crop yield and the protein content values and also the digestible protein yield values were calculated. To examine the relationship between crop yield and crude protein yield and also between crop yield and digestible crude protein yield regression analysis were used. The overall results of this experiment indicate that the average crude protein digestibility of the tested soybean varieties was 76.0%, with an absolute difference of 17.3% between the best and the least digestible varieties. ES Mentor variety reached the best digestible crude protein yield, with 1305.4 kg/ha. The variety with the lowest digestible crude protein yield was Boglár, with 752.3 kg/ha. The difference in digestible crude protein yield between these two varieties was 173.5%. In the correlation analysis between digestible crude protein content and yield for soybean varieties our results show that there is no correlation between the two factors. However, Aires, Prestopro, and ES Mentor should be highlighted among the varieties with above trend line results, as they have the best yield (4020 kg/ha; 4100 kg/ha, 4510 kg/ha) and digestible crude protein content (31%, 30.3%, and 28.9%). ES Mentor produced the fourth best digestible crude protein content (28.9%) with the best yield (4510 kg/ha).
