Published: December 2023

ABSTRACT
Although seismological networks have densified along the Ecuadorian active margin since 2010, visual phase reading, ensuring high arrival times quality, is more and more time-consuming and becomes impossible to handle for the very large amount of recorded seismic traces, even when preprocessed with a detector. In this article, we calibrate a deep-learning-based automatized workflow to acquire accurate phase arrival times and build a reliable microseismicity catalog in the central Ecuadorian forearc. We reprocessed the dataset acquired through the OSISEC local onshore–offshore seismic network that was already used by Segovia et al. (2018) to produce a reference seismic database. We assess the precision of phase pickers EQTransformer and PhaseNet with respect to manual arrivals and evaluate the accuracy of hypocentral solutions located with NonLinLoc. Both the phase pickers read arrival times with a mean error for P waves lower than 0.05 s. They produce 2.7 additional S-labeled picks per event compared to the bulletins of references. Both detect a significant number of waves not related to seismicity. We select the PhaseNet workflow because of its ability to retrieve a higher number of reference picks with greater accuracy. The derived hypocentral solutions are also closer to the manual locations. We develop a procedure to automatically determine thresholds for location attributes to cull a reliable microseismicity catalog. We show that poorly controlled detection combined with effective cleaning of the catalog is a better strategy than highly controlled detection to produce comprehensive microseismicity catalogs. Application of this technique to two seismic networks in Ecuador produces a noise-free image of seismicity and retrieves up to twice as many microearthquakes than reference studies.
Modeling Natural Frequencies of Vibration of Three Dimensional Frames under Two Dimensional Loading
Authors: Mutala Gideon Nzioki 
Published: December 2023

The aim of this study was to determine the relationship between natural frequency of vibration, the height of the structure, the stiffnesses of members and number bays of a structure. The relationship was to be developed based on data obtained using two methods. The methods were theoretical and experimental. In the theoretical method Computer Modeling was done based on structural theory. In the experimental method physical prototypes of structures were made to vibrate freely.
In the theoretical approach, a matrix approach a computer program which generated structural models was developed using a matrix method. A horizontal force would be input at a top joint of each model and deflection at the centre of mass was calculated. The deflection was the amplitude of vibration. The stiffness of the structure was then calculated using the structural amplitude obtained. The stiffness would then be used to calculate the natural frequency of vibration for the structural model.
In the experimental approach, physical miniature structures were fabricated with different heights, member stiffnesses and number of bays. An increasing force would be applied on each structure using a magnet which would release it, at a certain magnitude of force, to vibrate freely. Deflections against time at the centre of mass were then measured using an horizontal motion transducer. The transducer has a probe which gets depressed on contact with a vibrating object. The instrument was connected to a TDS 302 data-logger which displayed deflection against time on a screen.
Analysis of data obtained from the two approaches was done using a graphical method. The experimental data correlated very closely to the theoretical data. The results of the analysis enabled development of a formula for obtaining the natural frequency of vibration using the various parameters. The formula will aid the engineering design of tall buildings such that they do not resonate with the forces acting on them. In this way it will be possible to avoid catastrophic resonance disasters.

Vanili umumnya disimpan untuk tahap penuaan selama 2-6 bulan sehingga memicu pertumbuhan mikrob. Teknologi iradiasi dapat diterapkan untuk mereduksi mikrob pada vanili tujuan ekspor. Tujuan penelitian adalah menguji efektivitas iradiasi gamma terhadap mutu vanili hasil curing serta menentukan dosis iradiasi terbaik dengan mutu masih diterima oleh konsumen. Rancangan percobaan adalah rancangan acak lengkap faktorial dengan tiga ulangan. Faktor pertama dosis iradiasi sebanyak tiga taraf yaitu 10, 15 dan 30 kGy serta tanpa iradiasi (0 kGy) sebagai kontrol. Faktor kedua adalah bahan baku vanili hasil curing sebanyak tiga taraf yaitu vanili curing dengan pengering efek rumah kaca (ERK) tanpa peram lanjut, vanili curing dengan pengering ERK dan peram lanjut empat malam serta vanili curing hasil penjemuran petani. Pemberian iradiasi dilakukan pada vanili setelah penyimpanan selama dua bulan. Pengujian parameter mutu dilakukan sebelum dan sesudah iradiasi pada sampel yang dikemas, meliputi, fisik, kimia, mikrobiologi, dan uji organoleptik. Dosis iradiasi 10 kGy ditemukan efektif untuk mengurangi cemaran mikrobiologi pada vanili tanpa peram dan dengan peram lanjut sesuai batas cemaran SNI, namun pada vanili penjemuran petani dibutuhkan dosis 15 kGy. Dosis iradiasi tidak memberi efek terhadap susut bobot, kadar air dan kadar vanilin sehingga mutu dan aroma masih baik. Iradiasi meningkatkan nilai L* dan chroma namun kesukaan panelis terhadap warna vanili masih bernilai 4 (agak suka) hingga 30 kGy. Pemberian iradiasi meningkatkan kesukaan panelis terhadap aroma dari agak tidak suka (3) sebelum diiradiasi menjadi agak suka (4) setelah diiradiasi.

Strong Association Between Growth Hormone Therapy and Proximal Tibial Physeal Avulsion Fractures in Children and Adolescents
Authors: Beber Samuel A. , Gross Preston W. , Nichols Erikson , Green Daniel W. , Fabricant Peter D. 
Published: December 2023

Background:
Published literature describes slipped capital femoral epiphysis as a complication of recombinant human growth hormone (rhGH) therapy that may be related to decreased physeal strength. The purpose of the current investigation was to utilize a case-control study design to determine whether a greater proportion of pediatric patients sustaining physeal avulsion fractures of the proximal tibia were undergoing rhGH therapy at the time of injury compared with a cohort of matched controls.

Methods:
A case-control design study design was utilized. Patients 4 to 18 years of age with proximal tibial physeal avulsion fractures (cases) or midshaft tibial fractures (controls) at our institution from February 1, 2016, to May 4, 2023, were identified. Cases and controls were matched 1:1 on the basis of age (within 1 year), sex, and body mass index (within 3 kg/m2). A total of 132 patients were included in the analysis (mean age, 13 ± 2 years). rhGH exposure was compared using conditional logistic regression with Firth correction.

Results:
We found that 11% of the patients with a proximal tibial physeal avulsion fracture were on rhGH therapy at the time of injury compared with 0% of patients with midshaft tibial fractures (odds ratio [OR], 15.0; 95% confidence interval [CI], 1.8 to 1,946.7; p = 0.007). There was no significant difference in the proportion of sports-related injuries between cases (70%) and controls (67%) (OR, 1.15; 95% CI, 0.55 to 2.39; p = 0.85). Among subjects with proximal tibial avulsion fractures, the proportion requiring surgery did not differ significantly between patients receiving and those not receiving rhGH therapy (43% versus 41%, respectively; p = 0.99).

Conclusions:
This study demonstrates that the proportion of subjects who sustained proximal tibial physeal avulsion fractures and were receiving recombinant human growth hormone therapy at the time of injury was significantly greater than that of an age, sex, and body mass index-matched control group with midshaft tibial fractures (11% versus 0%, respectively, representing 15-times greater odds of exposure). This quantifies a previously unreported serious orthopaedic complication associated with rhGH therapy.

Level of Evidence:
Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
Differentiation of Lamproitic Magma: Case Study of Mesozoic High-K Dikes of the Ryabinovyi Massif (Central Aldan)

Published: December 2023

Abstract
––Studies of the mineral–petrographic and geochemical compositions of high-potassic lamprophyric dikes of the Tobuk complex, manifested at the Ryabinovyi plutonic massif (Central Aldan Mesozoic magmatic province, Russia), have shown that these dikes compose a single fractionation series formed from a high-Mg lamproitic parental melt in an intermediate chamber. The composition of the rocks ranges from olivine–diopside–phlogopite and diopside–phlogopite lamproites through minettes to microsyenites and syenite–porphyry. Early crystallization of high-Mg olivine and chromite in an intermediate chamber could produce cumulative dunites similar to those of the Inagli intrusion. Crystallization of olivine and chromite was followed by cotectic crystallization of olivine and clinopyroxene, then that of clinopyroxene and phlogopite, and, finally, eutectic crystallization of Na-rich clinopyroxene, phlogopite, and K-feldspar. Crystallization and gravitational differentiation of lamproitic melt was complicated by silicate–carbonate immiscibility, which is texturally manifested in minettes as carbonate–silicate globules and interstitial calcium and magnesium carbonates. Furthermore, compositional zoning of Sr in apatite and Ba in phlogopite and K-feldspar is considered to have resulted from the immiscibility. Separation of the carbonate–fluorite melt fraction might have led to formation of the carbonatite and fluorite–carbonatite schlieren and gangues which have been described in drill cores from the Ryabinovyi massif. In most of the geochemical and mineralogic features, the Ryabinovyi massif lamproites are similar to the low-Ti lamproites of the Mediterranean postcollisional belt and northern Vietnam and differ from typical high-Ti within-plate lamproites.

Published: December 2023

Abstract
––The Udokan sedimentary basin is a unique geological structure containing many copperstone deposits and occurrences. A detrital chrome spinel is identified in the metasandstones of the Sakukan Formation at the Udokan and Unkur deposits, which tend to interlayers of natural heavy mineral concentrates. The mineral forms relict inclusions in magnetite crystals. Its composition is distinguished by high concentrations of zinc (up to 11.62 wt.% ZnO) and manganese (up to 6.32 wt.% MnO) with an almost complete absence of magnesium. In comparison with the associated magnetite, chromite is significantly enriched in germanium (up to 666 ppm) and gallium (up to 59.1 ppm). The formation of Zn-chrome spinel occurred during the transformation of detrital chromite against the background of specific chemical processes accompanying the deposition and crystallization of iron gel enriched with adsorbed impurities.

Abstract

Alcoholic beverages are a part of the human dietary culture. In Africa, fermented alcoholic beverages are consumed on different occasions. Beverage production depends on the type of food, fermentation process duration, and application of microbes utilized for fermentation. Ethiopia is one of the countries where many traditional fermented beverages are prepared and consumed. Tej, Areki, Tella, kribo, borde, and korfe are the most common. However, information regarding this indigenous product is limited. Most of the recipes and the preparation methods are not documented and studied. This study was undertaken to collect indigenous knowledge, practices, mode of preparation, and skills, as well as to generate data on the functional properties and chemical composition of Tej and Araki. The study includes information on ingredients, pH, electrical conductivity, specific gravity, methanol and ethanol content, total acidity, esters content, and acetaldehyde content. Previous research supports the findings, indicating consistency in the characteristics of Tej and Areki across studies.
