Структура конечной групповой алгебры одного полупрямого произведения абелевых групп и её приложения
Authors: Веденёв Кирилл Владимирович , Деундяк Владимир Михайлович
Published: February 2020

В 1978 году Р. Мак-Элисом построена первая асимметричная кодовая криптосистема, основанная на применении помехоустойчивых кодов Гоппы, при этом эффективные атаки на секретный ключ этой криптосистемы до сих пор не найдены. К настоящему времени известно много криптосистем, основанных на теории помехоустойчивого кодирования. Одним из способов построения таких криптосистем является модификация криптосистемы Мак-Элиса с помощью замены кодов Гоппы на другие классы кодов. Однако, известно что криптографическая стойкость многих таких модификаций уступает стойкости классической криптосистемы Мак-Элиса. В связи с развитием квантовых вычислений кодовые криптосистемы, наряду с криптосистемамми на решётках, рассматриваются как альтернатива теоретико-числовым. Поэтому актуальна задача поиска перспективных классов кодов, применимых в криптографии. Представляется, что для этого можно использовать некоммутативные групповые коды, т.е. левые идеалы в конечных некоммутативных групповых алгебрах.Для исследования некоммутативных групповых кодов полезной является теорема Веддерберна, доказывающая существование изоморфизма групповой алгебры на прямую сумму матричных алгебр. Однако конкретный вид слагаемых и конструкция изоморфизма этой теоремой не определены, и поэтому для каждой группы стоит задача конструктивного описания разложения Веддерберна. Это разложение позволяет легко получить все левые идеалы групповой алгебры, т.е. групповые коды. В работе рассматривается полупрямое произведение $$Q_{m,n} = (\mathbb{Z}_m \times \mathbb{Z}_n) \leftthreetimes (\mathbb{Z}_2 \times \mathbb{Z}_2)$$ абелевых групп и конечная групповая алгебра $$\mathbb{F}_q Q_{m,n}$$ этой группы. Для этой алгебры при условиях $$n \mid q -1$$ и $$\text{НОД}(2mn, q) = 1$$ построено разложение Веддербёрна. В случае поля чётной характеристики, когда эта групповая алгебра не является полупростой, также получена сходная структурная теорема. Описаны все неразложимые центральные идемпотенты этой групповой алгебры. Полученные результаты используются для алгебраического описания всех групповых кодов над $$Q_{m,n}.$$

Authors: Syauki Ahmad Yanuar
Published: February 2020

Dalam penulisan penelitian ini akan diperhitungkan data trafik SCADA (Supervisory Control And Data Acquisition) yang digunakan untuk sistim monitoring, kontrol dan akuisisi data dari instrument di setiap station gas dan trafik penggunaan komunikasi suara suara yang ditumpangkan pada media komunikasi VSAT (Very Small Aparture Terminal) yang kesehariannya digunakan di setiap stasiun gas sebagai media komunikasi antar stasiun gas atau hubungan komunikasi antara stasiun gas dengan MCS (Master Control System) sebagai sistem kesatuan yang terintegrasi untuk mempermudah pengoperasian penyaluran gas.Metode penelitian yang digunakan adalah memperhitungkan bandwidth yang digunakan sebelum terjadi kegagalan atau failled pada saat pengiriman data dan suara. Adapun cara yang digunakan adalah membuktikan batas maksimum bandwidth existing berdasarkan perhitungan pemakaiaan trafik yang digunakan sesuai dengan jumlah instrument yang ada di lapangan yang selanjutnya dibandingkan dengan bandwidth VSAT yang telah tersedia.Bandwidth 64 Kbps untuk setiap stasiun gas cukup untuk keadaan penggunaan 3 trafik voice yang digunakan secara bersamaan dengan penggunaan data SCADA saja namun apabila keadaan penggunaan trafik voice >3 panggilan suara secara bersamaan maka akan terjadi kegagalan penerimaan data SCADA dikarenakan keterbatasan bandwidth hal ini terbukti dengan perhitungan keadaan dengan 4 trafik voice yang terpakai secara bersamaan yaitu rata-rata trafik di atas 64000 bps yaitu 70461 bps. Media transmisi VSAT dapat digunakan untuk trafik data SCADA dan suara secara bersamaan memiliki Quality of Service (QoS) cukup baik Kata kunci : VSAT, SCADA, Voip dan Trafik
Unmasking Identity: Observations From a Cohort of Entering Medical Students
Authors: Stephens Mark B.
Published: February 2020

Background and Objectives: Professional identity formation (PIF) is increasingly recognized as a core element of medical education. The use of narrative reflection is traditionally the most common means to explore PIF. We explored the use of mask-making as a process of reflective expression to encourage iterative exploration of professional identity in medical students. This project focused on elements of personal and professional identity in a cohort of entering students.
Methods: One hundred fifty entering students at the Pennsylvania State University College of Medicine created a mask to use descriptive words to express their perceptions of an ideal physician (external face of the mask) and their sense of self (internal face of the mask). Responses were compared to established domains of professional identity.
Results: Students most commonly listed elements in the domain of personal characteristics to describe both their sense of self and of an ideal physician. Students were more likely to list emotional elements when describing self and more likely to use elements in the domains of relationships, attitudes, and duties/responsibilities when describing an ideal physician.
Conclusions: The beginning of medical school is a time of significant transition. Mask making can blend visual and narrative arts to provide a complementary tool to examine professional identity formation.
EHR Overtime: An Analysis of Time Spent After Hours by Family Physicians
Authors: Anderson Jacob , Leubner Jason , Brown Steven R.
Published: February 2020

Background and Objectives: Time spent in the electronic health record (EHR), away from direct patient care, is associated with physician burnout. Yet there is a lack of evidence quantifying EHR use among family physicians. The purpose of the study was to describe a method for quantifying habits and duration of use within the electronic health record in family medicine residents and faculty with particular attention paid to time spent after hours.
Methods: We audited EHR time for family medicine residents and faculty using an EHR vendor-provided, web-based tracking system. We collected and analyzed the number of patient encounters, total time in the EHR per patient, total time in the EHR after hours by physicians for a 6-month time period.
Results: Over the 6-month period reviewed, family medicine trainees and faculty saw between one and 164 patients monthly, spent between 17 and 217 minutes in the EHR per patient, and spent between 0 and 33 hours in the EHR after hours per month.
Conclusions: Family medicine residents spend a significant amount of time completing EHR tasks after hours. Objective EHR data can be used by family medicine residency programs to devise interventions to decrease inefficient use of the EHR, decrease after-hours EHR use, and improve well-being.

Authors: Valadares de , Bachmann Guimarães , Vieira Rafael , de Araújo , Jerônimo de , Yamamoto Carlos , Ulson de , de Arruda
Published: February 2020

The purpose of this paper is to present the third stage of regeneration for ecat: deactivated or equilibrium catalysts which are waste from fluidized catalytic cracking (FCC) units. This stage is going to compose a complete circular economy (CE) model and increase the life cycle of the catalyst. The third stage of regeneration, after the adsorption process for sulfur and nitrogen compounds from real diesel, was assessed using as solvents: acetone (propanone), ethanol, benzene and toluene. For sulfur and nitrogen compounds, ethanol achieved the best performance. The variations of physical and chemical properties of regenerated ecats in the cycles of adsorption and desorption were evaluated using x-ray diffraction, x-ray fluorescence, nitrogen adsorptiondesorpion, thermogravimetric and differential thermal analysis, scanning electron microscopy and Fourier-transform infrared spectroscopy. The recovery rate over four cycles is superior for sulfur compounds. After all cycles, ecat-R- -SA exhibited 5.09% reduction in the recovery for sulfur and 24.58% reduction in the recovery for nitrogen. The nitrogen adsorption-desorption analysis suggests the adsorption of compounds by ecat-R may be more correlated with the adsorption sites than with specific area. Overall, the results of this work are promising and allows for ecat to integrate a complete CE model.
Analisa Postur Kerja Manual Material Handling (MMH) pada Karyawan Bagian Pembuatan Block Menggunakan Metode Rapid Upper Limb Assessment (RULA) (Studi Kasus: PT Asia Forestama Raya)
Authors: Hamdy Muhammad Ihsan
Published: February 2020

Sistem kerja yang tidak ergonomis dalam satu perusahaan seringkali kurang mendapat perhatian dari pihak manajemen perusahaan. Salah satu bagian sistem yaitu pekerja. Pekerja yang ada di suatu pabrik biasanya banyak melakukan sikap dan posisi kerja yang kurang ergonomis. Hal ini secara sadar ataupun tidak akan berpengaruh terhadap produktifitas, efisiensi dan efektivitas pekerja dalam menyelesaikannya. Posisi kerja yang dimaksud seperti postur kerja dengan aktivitas Manual Material Handling (MMH). Cidera atau kecelakaan kerja yang terjadi akibat aktivitas MMH ini selain merugikan pekerja secara langsung atas rasa sakit yang diderita, juga berdampak buruk bagi kinerja perusahaan yaitu penurunan produktivitas perusahaan. Penelitian ini menggunakan metode Rapid Upper Limb Assessment (RULA). RULA adalah  metode  yang dikembangkan dalam bidang ergonomi yang menginvestigasikan dan menilai posisi kerja yang dilakukan oleh  tubuh  bagian atas. PT. Asia Forestama Raya merupakan sebuah industri yang memproduksi plywood untuk ekspor maupun lokal. Dimana pada perusahaan ini masih terdapat aktivitas manual yaitu pada bagian pembuatan block. Pada penelitian ini di bagikan kuesioner Nordic Body Map untuk mengidentifikasi keluhan apa saja yang dirasakan oleh pekerja. Keluhan yang dirasakan pekerja terasa hampir pada seluruh anggota tubuh pekerja. Keluhan yang paling banyak dirasakan pekerja diantaranya adalah sakit pada punggung sebesar 47,14%. Sedangkan sakit pada pinggang adalah sebesar 44,30%, serta sakit pergelangan tangan kanan dan kiri masing-masing sebesar 44,17% dan 44,30%.   Penelitian ini bertujuan untuk mengetahui dan menganalisa kategori postur  kerja dari pekerja pembuatan block    di  PT. Asia Forestama Raya. Dari pengolahan data yang telah dilakukan, pada posisi pertama dan kedua didapat action level 4 dengan skor akhir sebesar 7, berarti kondisi ini berbahaya sehingga pemeriksaan dan perubahan posisi kerja harus dilakukan (saat itu juga). Hal ini disebabkan postur kerja ini dilakukan dalam rentang waktu berulang sehingga dapat membahayakan pekerjanya. Sedangkan pada postur kerja ketiga dan kelima terlihat bahwa postur kerja berada pada action level 3 dengan besar skor akhir adalah 5. Dimana pada level ini diperlukan perbaikan postur kerja se-segera mungkin. Berbeda pada postur kerja keempat, didapat skor akhir sebesar 4, postur kerja ini termasuk dalam kategori action level 2 yang berarti tidak begitu membahayakan pekerjanya. Namun akan berbahaya jika dilakukan terus-menerus sehingga apabila semakin cepat dilakukan perbaikan akan lebih baik.

Calidad de poroto (Phaseolus vulgaris L.) almacenado en silobolsa en condiciones de intemperie en relación a la presencia de materias extrañas y granos partidos
Authors: Godoy Adriana Iris
Published: February 2020

El objetivo del trabajo fue estudiar el deterioro del poroto blanco alubia almacenado en silobolsa con la presencia de materias extrañas y granos partidos. Se evaluaron silobolsas con diferentes contenidos iniciales de humedad, materias extrañas, granos partidos y granos manchados. Se midió la evolución de estos parámetros y la concentración de dióxido de carbono. Se registró humedad relativa y temperatura del aire intergranario. Se utilizó la actividad acuosa como parámetro de actividad microbiana. Los resultados indican que el manchado de los granos aumentó con altos contenidos iniciales de manchado, humedad y materias extrañas, que coincidió con el incremento de microorganismos. Estos últimos se localizaron según la ubicación del material fino en la base de la bolsa, o en puntos húmedos del estrato superior producto de la condensación. Bajos valores de humedad y materias extrañas evidenciaron control microbiano por humedad relativa <70%. Se observó interacción entre los efectos de materias extrañas y granos partidos, que generó el manchado de los granos, favorecida por períodos prolongados y altas temperaturas. El efecto de los granos partidos se relacionó con el contenido de humedad y el efecto del material extraño con el tiempo. Se observó la estratificación de la humedad. La concentración de dióxido de carbono aumentó con el incremento de la temperatura. Los incrementos de la actividad acuosa se relacionaron con altas proporciones de materias extrañas y granos partidos presentes en el granel, y con elevados contenidos de humedad de los mismos y del grano, lo cual ocasiona mayor actividad microbiológica.

Published: February 2020

Una alternativa al uso indiscriminado de fitosanitarios es la incorporación de microorganismos antagónicos competitivos para la protección de los cultivos de los patógenos habitantes del suelo. En este trabajo se evaluó la potencialidad del establecimiento de Trichoderma harzianum Rifai (cepa Th5cc) en el suelo bajo diferentes formulaciones, con el objeto de conocer cuál es la más efectiva en mantener la población del antagonista a niveles moderados. La población se cuantificó mediante la técnica del suelo diluido en placa utilizando un medio selectivo para Trichoderma. Los resultados muestran que tanto en el formulado líquido como en las semillas recubiertas aumenta la población de Th5cc hasta los 90 días desde que se incorporó el formulado al suelo (1,4 x 104 unidades formadoras de colonia/g de suelo). En contraste, con la aplicación de formulado sólido la población del antagonista comienza a disminuir a los 90 días. En el caso de la incorporación en la semilla, la población de T. harzianum al inicio fue menor a la del testigo, pero a los 60 y 90 días alcanzaron valores mayores a la población original del suelo (testigo). La eficiencia de la aplicación de T. harzianum como antagonista en plantas está estrechamente relacionada con su formulación, la cual tiene una clara influencia en la supervivencia en el suelo.

Published: February 2020

No Brasil, o feijoeiro é cultivado em três safras, com cada uma necessitando de diferentes níveis tecnológicos para a obtenção de elevadas produtividades. Entretanto, estudos para avaliar o efeito da safra na produtividade e qualidade dos grãos em cultivares de feijoeiro são escassos. Desta forma, objetivou-se avaliar e comparar o desempenho de cultivares de feijoeiro do grupo comercial carioca, quanto às características agronômicas e tecnológicas dos grãos, cultivadas na safra das águas e de inverno, bem como indicar os melhores genótipos para serem cultivados em cada época. O delineamento experimental utilizado foi o de blocos casualizados, apresentando 20 tratamentos, com 10 cultivares de feijão e 2 safras de cultivo, em três repetições. Foram avaliados os atributos agronômicos: número de vagens por planta, número de grãos por vagem, massa de 100 grãos e produtividade de grãos, e os atributos tecnológicos dos grãos, sendo eles o tempo de cozimento, relação de hidratação e o tempo para a máxima hidratação dos grãos. A produtividade e a relação de hidratação dos grãos das cultivares de feijão foram superiores na safra de inverno. A safra de inverno apresentou maior tempo para a máxima hidratação dos grãos do que a safra das águas, entretanto o tempo para cozimento dos grãos não foi afetado. Nas condições de estudo, recomenda-se para a safra de inverno a cultivar BRS MG Requinte e para a safra das águas a cultivar BRS MG Horizonte. A cultivar BRS MG Talismã é recomendada tanto para cultivo na safra das águas como na safra de inverno.

Motivation is something that is very important for someone in doing an activity. Motivating learning motivation can encourage optimal learning achievement. Motivation has a very important role in individual activities. Motivation needs for  individual activities to produce effective results, there is a need for strong motivation and for this reason efforts are needed to generate motivation. Many teachers feel that their job is only to teach, not to motivate students. When in the classroom the teacher solely conveys the contents of the lesson to the students, in terms of conveying the lesson where students do not feel attracted by the lesson which is less favorable. Students need to get motivated. A student who has motivation will be able to learn more and faster than those who lack motivation

            Teacher communication with students in face-to-face activities in the teaching and learning process can be done, both individually or in groups, in the form of verbal and non-verbal, and assisted with media and learning resources. The teacher provides information, messages, ideas to students with the intention of students actively participating well in learning so that the core of the learning process can be achieved to the maximum level

desmame precoce é um desafio mundial e os profissionais de saúde tem um papel importante no apoio a amamentação exclusiva. O objetivo deste trabalho é identificar os fatores relacionados ao desmame precoce e o papel do enfermeiro na promoção do aleitamento materno, da assistência no pré-natal e na puericultura da atenção básica à área hospitalar; pré-parto, parto e puerpério.Trata-se de  um estudo descritivo a partir de uma revisão bibliográfica crítica, realizada por meio de busca em base de dados de artigos científicos. O estudo permitiu compreender que a prática do aleitamento materno traz benefícios tanto para a mãe, quanto para o bebê, além de reforçar o vínculo entre eles . Sabendo que o desmame precoce ocorre por diversos fatores como: a idade materna, primariedade, baixo nível de escolaridade, uso precoce de fórmulas lácteas e chupetas, patologias relacionadas às mamas, trabalho materno, urbanização, tabagismo, falta de incentivo da família e da sociedade, além de deficiências na atenção à saúde, cabe ao enfermeiro garantir a continuidade do aleitamento materno através de educação em saúde no pré-natal, parto e no puerpério, principalmente nos primeiros dias após o parto além de envolver a família nesse momento.

Published: February 2020

Background:

Hemostasis plays an important role in safe brain tumor resection and also reduces the risk for surgical complications. This study aimed to evaluate the efficacy of FLOSEAL®, a topical hemostatic agent that contains thrombin and gelatin granules, in brain tumor resections.

Methods:

We evaluated the hemostatic effect of FLOSEAL by scoring the intensity of bleeding from 1 (mild) to 4 (life threatening). We assessed the rate of success of hemostasis with 100 patients who underwent intracranial tumor resection. We also investigated the duration of the operation, the amount of intra- and postoperative bleeding, the number of hospital stays, and adverse events in patients who used FLOSEAL compared with those who did not use FLOSEAL.

Results:

FLOSEAL was applied to a total of 109 bleeding areas in 100 patients. A total of 95 bleeding areas had a score of 1 and 91 (96%) showed successful hemostasis. Thirteen bleeding areas scored 2 and 8 (62%) showed hemostasis with the first application of FLOSEAL. The second application was attempted with five bleeding areas and four showed hemostasis. About 94% (103/109 areas) of bleeding points successfully achieved hemostasis by FLOSEAL. Moreover, FLOSEAL significantly decreased the amount of intraoperative bleeding and postoperative bleeding as assessed with computed tomography on 1 day postoperatively compared with no use of FLOSEAL. There were no adverse events related to FLOSEAL use.

Conclusion:

Our results indicate that FLOSEAL is a reliable, convenient, and safe topical hemostatic agent for intracranial tumor resection.
Spinal intramedullary epidermoid cysts: Three case presentations and literature review
Authors: Rahimizadeh Abolfazl , Sharifi Guive
Published: February 2020

Background:

True intramedullary epidermoid cysts (IECs) not associated with congenital anomalies or previous spinal procedures are extremely rare. In a review of the literature since 1992, only 29 such cases have been reported. Here, we add three new cases in this category.

Case Description:

Three adults presented with spastic paraparesis attributed to thoracic IECs. Gross total microsurgical removal was achieved in two cases, while one case was a partial resection due to capsular adherence to the cord. In all three cases, patients sustained complete recoveries of neurological function and remained symptom free for an average of 5 years follow-up.

Conclusion:

IECs are rare lesions; here, the three located in the thoracic spine, contributed to slow, progressive spastic paraparesis with/without incontinence, and resolved following total (2 patients) and partial (1 patient) resection.

Published: February 2020

The one-pot sulfonylation/aminoalkylation of styrene derivatives furnishing highly substituted gamma-sulfonylamines was accomplished through a photoredox-catalyzed four-component reaction. Apart from one molecule of water and the sodium counterion of the sulfinate, all atoms of the starting materials are transferred to the final product, rendering this process highly atom-efficient. The operationally simple protocol allows for the simultaneous formation of three new single bonds (C–S, C–N, and C–C) and therefore grants rapid access to structurally diverse products. The reaction proceeds under mild conditions in aqueous acetonitrile and shows a broad scope, including natural products and drug-like molecules.
Ni-Catalyzed Electrochemical C(sp2)−C(sp3) Cross-Coupling Reactions

Published: February 2020

Nickel (Ni) catalyzed carbon-carbon (C−C) cross-coupling has been considerably developed in last decades and has demonstrated unique reactivities compared to palladium. However, existing Ni catalyzed cross-coupling reactions, despite success in organic synthesis, are still subject to the use of air-sensitive nucleophiles (i.e. Grignard and organozinc reagents), or catalysts (i.e. Ni0 pre-catalysts), significantly limiting their academic and industrial adoption. Herein, we report that, through electrochemical voltammetry screening and optimization, the redox neutral C(sp2)‒C(sp3) cross-coupling can be accomplished in an undivided cell configuration using bench-stable aryl halide or β-bromostyrene (electrophiles) and benzylic trifluoroborate (nucleophiles) reactants, non-precious, bench stable catalysts consisting of NiCl2•glyme pre-catalyst and polypyridine ligands under ambient conditions. The broad reaction scope and good yields of the Ni-catalyzed electrochemical coupling reaction were confirmed by 48 examples of aryl/β-styrenyl chloride/bromide and benzylic trifluoroborates. Its potential applications were demonstrated by late-stage functionalization of pharmaceuticals and natural amino acid modification. Furthermore, this electrochemical C−C cross-coupling reaction was demonstrated at gram-scale in a flow-cell electrolyzer for practical industrial adoption. Finally, an array of chemical and electrochemical studies mechanistically indicates that electrochemical C−C cross-coupling reaction proceeds through an unconventional radical trans-metalation mechanism.
Modification of Layered Double Hydroxides Using First-Row Transition Metals for Superior UV-Vis-NIR Absorption and the Influence of the Synthesis Method Used
Authors: Gevers Bianca , Naseem Sajid , Sheppard Charles , Leuteritz Andreas , Labuschagne Johan
Published: February 2020

Layered double hydroxides (LDHs) with high and tailorable UV-Vis-NIR absorption were prepared through transitionmetal (TM) modification. The synthesis method used and amount of TM present were found to influence the UV-Vis-NIR absorption intensity, -range, and the optical bandgap.It was found that the incorporation of TMs in MgAl-LDH results in the existence of a "UV-Vis-NIR absorption fingerprint", the intensity of which can be tuned by the amount of TM present. There also exist differences in the UV-Vis-NIR absorption spectra and bandgaps obtained for MgAl-LDH synthesised using different synthesis conditions and methods, but these are not as visible when including transition metals. Further, the materials exhibit very complex spectra for which adequate explanation is lacking in literature. Finally, standard methods to determine the bandgap of materials, did not give conclusive results for all materials, only for some, and indicate that some of the materials might have multiple different transition types.

The development of drugs for birth-control has changed society, and they are used by billions of woman on an every day basis. As for every mass product, there are problems associated with the waste it causes. One has found that residues of hormones in the urine of woman cannot be removed sufficiently from waste-water and this, in-turn, has already observable and undesired consequences in the biosphere. Apart from the removal of drugs, one is in general seeking new methods for the removal of hydrophobic impurities from waste-water. An ideal system would quantitatively take up the impurity, entrap it followed by preferably simple separation. Finally, one wants to reuse the absorbent, which implies the possibility for regeneration and recycling. Such as complex set of tasks requires a relatively complex materials architecture. Functional organic polymers with high affinity towards the drug, with stable open porosity and high surface area, stimuli-responsive properties and in the form of colloidal dispersions could do the job. Unfortunately, such a system does not exist. We solved this problem by generating mesoporous organosilica nanoparticles, which are monomers at the same time. Initiation of the polymerization reaction by surface-bound pore-walls leads to the formation of a special type of block-copolymer. The pore-walls are covered by the polymer, which cannot leach. An orthogonal modification was achieved by modification of the external surfaces of the particles with a thermoresponsive polymer by click-chemistry. The final core-shell system was able to remove hydrophobic molecules such as the hormone progesterone from water. A change of temperature induces the collapse of the thermoresponsive polymer, which closes the pores and induces aggregation of the particles. After separation of the particles, and thus also the entrapped impurity, from the solvent, one can re-open the pores, which leads to a release of the adsorbed compound(s).

Machine learning (ML) methods have become powerful, predictive tools in a wide range of applications, such as facial recognition and autonomous vehicles. In the sciences, computational chemists and physicists have been using ML for the prediction of physical phenomena, such as atomistic potential energy surfaces and reaction pathways. Transferable ML potentials, such as ANI-1x, have been developed with the goal of accurately simulating organic molecules containing the chemical elements H, C, N, and O. Here we provide an extension of the ANI-1x model. The new model, dubbed ANI-2x, is trained to three additional chemical elements: S, F, and Cl. Additionally, ANI-2x underwent torsional refinement training to better predict molecular torsion profiles. These new features open a wide range of new applications within organic chemistry and drug development. These seven elements (H, C, N, O, F, Cl, S) make up ~90% of drug like molecules. To show that these additions do not sacrifice accuracy, we have tested this model across a range of organic molecules and applications, including the COMP6 benchmark, dihedral rotations, conformer scoring, and non-bonded interactions. ANI-2x is shown to accurately predict molecular energies compared to DFT with a ~106 factor speedup and a negligible slowdown compared to ANI-1x. The resulting model is a valuable tool for drug development that can potentially replace both quantum calculations and classical force fields for myriad applications.

Lipid Nanoparticles have gained increased attention during the last few decades. These carrier systems offer many advantages over conventional drug delivery system, including protection of the entrapped active ingredient from environmental (pH) or physiological (immune system, enzymes) degradations, improved bioavailability, prolonged circulation time, sustained release of drug and site specific drug delivery, reduced dose and side effects.  Solid Lipid Nanoparticles (SLN), has been reported as an alternative carrier system to liposomes.  However, SLN show some disadvantages such as drug expulsion during storage, low drug loading and aggregation of the particles. Nanostructured lipid carriers are evolved as second generation lipid nanoparticles to overcome the limitations of SLN, by modifying SLN by incorporating liquid lipid to the solid matrix for better drug accommodation to increase drug loading and prevent drug leakage while preserving the physical stability of the formulation. This article describes the features, various preparation techniques, characterization techniques and the therapeutic applications of NLCs in topical drug delivery, brain, oral and pulmonary delivery.

Objectives: The physicochemical characteristics of bran of cassava starch flour and bran of cassava flour (viz. organoleptic characteristics, pH value, moisture content, total ashes, lipid, protein, starch and fiber contents) and biopharmacotechnical parameters (viz. granulometry, flow capacity, angle at rest, outflow time and apparent density) were evaluated aiming at assessing their potential use as tablet excipients. Methodos: Three tablet formulations of venlafaxine hydrochloride were proposed, having as excipients bran of cassava flour, bran of cassava starch flour and Starch 1500®. The tablets were produced using two different pressures (98±5 MPa and 32±6 Mpa) and their mechanical (hardness and friability) and dissolubility characteristics were evaluated. Results and Conclusions: The tablets produced with both cassava flours, using higher pressures, presented similar physicochemical characteristics to those obtained with the excipient Starch1500®, thus indicating that cassava flours possess the potential to be used as disintegrating agents in tablets.
