Published: January 2023

Case:

A 14-year-old adolescent girl sustained an open fracture of the foot after jumping off a building. Initial radiographs revealed large bone defect in the distal metaphysis of the comminuted tibia. The comminuted distal tibia was reconstructed by external fixation and internal fixation with bridge plating, followed by the Masquelet technique. After 12 months, the fracture healed without infection, and the patient could walk independently.

Conclusion:

In the case of a comminuted fracture of the contaminated distal tibia with a large bone defect, plate fixation and the Masquelet technique produced good outcomes.
Modified Eden-Lange Triple Tendon Transfer Procedure for Idiopathic Spinal Accessory Nerve Palsy and Scapular Winging
Authors: Radi Joshua K. , Hasegawa Morgan , Min Kyong S.
Published: January 2023

The scapula serves as the transition point at which the energy from the lower body and core transmits through the scapulothoracic articulation and the upper extremity. Spinal accessory nerve palsy leads to lateral winging of the scapula and abnormal scapulothoracic motion. Resultant abnormal motion and asynchrony of the scapulothoracic articulation can disrupt the upper extremity kinetic chain, leading to pain, atrophy, and dysfunction of the shoulder. Disruption of this kinetic chain can severely impair patients and athletes who engage in physically demanding activities. Conservative management alone with anti-inflammatories, lifestyle changes, and physical therapy has not produced encouraging results. Surgical management options include a tendon transfer (Eden-Lange, triple tendon transfer) or nerve repair. We present a case of an active duty service member with idiopathic spinal accessory nerve palsy treated with triple tendon transfer. After the triple tendon transfer, this patient experienced improvements in pain, range of motion, and function at 1-year postoperatively, also maintaining enough strength and function to pass their physical fitness assessments and remain on active duty. As such, these findings may suggest the triple tendon transfer procedure offers a viable option in the treatment of spinal accessory nerve palsy in the active patient populations who require a high level of physical function.
Writing fluency predicted by reading, linguistic and cognitive skills in L1 and L2 in the writing of bilingual biscriptal Persian-Swedish children
Authors: Johansson Baran , Rijlaarsdam Gert
Published: January 2023

Abstract                                               

Literacy acquisition in children’s L1 and L2 contributes to academic success, and embraces and supports children’s backgrounds and identity formation. However, limited education can prevent bilingual children from developing their writing fluency on the same level in L1 and L2. An analysis of writing fluency can show aspects that require more or less effort in children’s L1 and L2 writing. Thus, it is important to examine writing fluency and the related reading, linguistic and cognitive skills across children’s languages. Our knowledge is limited regarding the skills that could influence children’s writing fluency. Previous studies have mainly focused on Latin scripts and/or one alphabetic and one non-alphabetic script. Furthermore, English has been the writers’ L1 or L2. This paper investigated reading, linguistic and cognitive skills related to the writing fluency of bilingual biscriptal children in two different alphabetic scripts: Persian (L1) and Swedish (L2) across two different genres: narrative and descriptive. 23 children in years 4–9 (aged 10–15) produced four texts each using the Eye and Pen tool. Standardised tests across both languages were used to explore the participants’ reading, linguistic and cognitive skills. Analyses showed that they were more fluent writers across both genres in L2. Word reading appears to contribute to writing fluency across both languages, whereas vocabulary knowledge only related to writing fluency in L1. No significant relationship was found between working memory and writing fluency in either L1 or L2.

Co-Construction of beliefs regarding literature during the senior class – a project report
Authors: Dawidowski Christian , Witte Jennifer
Published: January 2023

In a literary didactical and educational sociological way, this empirical examination attempts to answer the question how students in senior classes of academic high schools (16–19 years) acquire and maintain notions and beliefs concerning literature. We assume that advanced-level German teaching at school has a huge impact on the realisation of these notions with regards to literature. Thus, this study focuses on how beliefs are alternatingly co-constructed. Our results underline the great influence of teachers in forming the beliefs about reading and literature of their students. They show the strong interdependence between teachers’ beliefs regarding reading and literature, the way teachers conduct class-talks in literature lessons and the emergence of students’ beliefs regarding literature in a decisive phase of growing up.

Preparation of CaMgAl-calcined layered double hydroxides and application on the removal of phosphates
Authors: Xiao Liping , Wang Zhemeng , Wang Dongxue , Lan Yunlong , Kong Qiaoping
Published: January 2023

A calcined CaMgAl-layered double hydroxide nanocomposite, CaMgAl-LDH (CCMA-0.83-600), was prepared by introducing Mg on the basis of CaAl-LDHs for the removal of phosphate from wastewater. The structure of the as-synthesized CCMA-0.83-600 was confirmed by XRD and SEM analyses. Parameters affecting the adsorption process of phosphate adsorbed by CCMA-0.83-600 were thoroughly explored, such as initial pH, adsorbent dosage and co-existing anions. The adsorption kinetic study suggested that the adsorption process accorded with the pseudo-second-order kinetic model and the adsorption rate was controlled by both the liquid film diffusion and intra-particle diffusion. The adsorption isotherm study indicated the adsorption process followed by the Langmuir isotherm model. Thermodynamic analysis suggested that the adsorption of phosphate was spontaneous and exothermic. The obtained results indicated that CCMA-0.83-600 is a suitable candidate for the removal of phosphate from wastewater.
Collecting Data of Late Recordings of Dragonflies in Poland in the Period of 2013-2020, as an Example of the Citizen Science
Authors: Tańczuk Agnieszka , Tończyk Grzegorz
Published: January 2023

The group “Ważki (Odonata) w Polsce” is an excellent example of citizen science, understood as a cooperation between society and professionals in scientific activity. The goal of the present paper is to show the data concerning the very late appearances of dragonflies and damselflies in the years 2013 – 2020, to enrich the knowledge about the phenology of various species in comparison to published data, which is no longer valid, taking into consideration the climatic changes over the last decades. It would not have been possible to gather such a great amount of information, if not for the amateurs engaged into a project like that (ca. 100 people). The data was catalogued according to date, place, and species. The main methods used were: the visual observation and taking photos of adult dragonflies. After thoroughly studying the data collected in early, middle, and late autumn (October, November, December), and analysing it carefully, the records were divided into three groups. The information gathered enables us to show the differences in phenology of some of the species. The project organised as a citizen science action, contributed to the increase of the knowledge concerning the late aspect of Polish odonato fauna.
Stakeholder Theory for Sustainable Cities and Society: A Humanist and Environmental approach for integrating People, Institutions, and Environmental Ecosystems
Authors: Beck Donizete
Published: January 2023

It needs to be clarified in the literature as to how humanism could embrace environmental ecosystems in cities and society. Some scholars argue that Stakeholder Theory could help bridge the environmental ecosystems under a humanist approach. For this reason, this study aims to fill this gap by exploring how Stakeholder Theory and Humanism can be connected to the fostering of sustainable development in cities and society. The main findings highlighted in the urban and societal contexts the role of stakeholder and humanist responsibility, the role of stakeholder consensus about humanist themes and environmental issues, and last but not least important, the need to consider the environment as a non-human stakeholder in social and urban governance. These directions should also be further detailed and explored in the multi/interdisciplinary fields of Sociology, Philosophy, Social Sciences, Humanities, Political Science, and Urban Studies. Therefore, this study provided a conceptual framework of three propositions which revealed that a stakeholder-oriented and humanism-oriented governance can embrace environmental concerns in cities and societies. In this way, consensus, responsibility, and considering the environment as a non-human stakeholder are critical elements in urban and social governance.
Environmental Ethics and the Need for Theory
Authors: Attfield Robin
Published: January 2023

Environmental ethics calls into question whether moral obligations invariably arise within relationships and communities, and whether wrong can only be done if some identifiable party is harmed. The aim of this paper is to appraise these assumptions, to argue for negative answers, and to draw appropriate conclusions about the scope of moral standing (or moral considerability). Its findings include the conclusions that our moral obligations (or responsibilities) extend to people and non-human creatures of the foreseeable future, as far as the impacts of present actions and policies can themselves be foreseen, that, that moral standing attaches to the possible people and other living creatures of the future, and (with Derek Parfit) that ethics is to some degree impersonal, being concerned with future quality of life for whoever lives in future centuries, whether they are currently identifiable or not. This in turn requires sustainable forms of social practice and of the human population. Another conclusion is that these findings are compatible with the approach of stewardship which the author has defended elsewhere, since stewardship need neither be anthropocentric nor managerial, and precludes current and future human agents treating the natural world as we please.

beam in the range 12−30 keV on the formation depth
of nonradiative recombination centers during etching of the
Al0.18Ga0.82As/GaAs/Al0.18Ga0.82As double heterostructure has
been studied. It is shown that an increase in the ion energy
leads to an increase in the concentration and propagation depth
of radiation defects. It was found that during etching of focused
ion beam with ion energies above 15 keV, the depth of formation
of radiation defects exceeds 900 nm, which does not correspond

An improved technique for thermal resistance mea-
surement of edge-emitting diode lasers using spontaneous emission
spectra, collected through the opening in the n-contact within the
range of operating currents, has been proposed. The advantage
of the proposed technique is that systematic errors typical for
measurements based on lasing spectra are excluded. The accuracy
of the method was verified by measuring the dependence of
the thermal resistance on the cavity length for diode lasers with
100 μm strip width. Obtained results are in good agreement with
the model, and the minimum measurement error was ±0.1 K/W.
The proposed technique can be used in metrological support of

t is shown that the description of the dispersive
transport of hole polarons based on the multiple capture model
makes it possible to quantitatively describe the kinetics of the
accumulation and relaxation of space charge in MOS- structures
after ionizing irradiation at low temperatures. Modeling of time
dependences of threshold voltage on temperature, electric field
strength and gate oxide thickness is carried out. It is shown that the
kinetics of space charge relaxation is determined by the hopping
transport of hole polarons with the levels of localized states in
the range of 0.08−0.55 eV, the concentration of polaron states,
the influence of the electric field strength on the average polaron
energy, as well as gate oxide thickness on dispersive parameter.
The polaron radius is estimated.

An epitaxial film of the Pd-Fe alloy 116 nm thick with an iron concentration varying in depth from 2 at.% to 50 at.% has been synthesized. An experimental depth distribution profile of iron was obtained as a result of stepwise etching of the film surface with Ar+ ions. Profiling showed that, as a result of annealing, the impurity was redistributed in the film, and a layer of the L10-phase with a constant concentration was formed near the film surface. After removal of the L10-phase, the film exhibits easy-plane anisotropy. The study of spin-wave resonance spectra showed the presence of several modes of standing spin waves, the number of which depends on the residual film thickness.

The activation parameters for various iron structures were calculated by the analytical method based on the paired four-parameter Mie–Lennard-Jones interatomic interaction potential. Within the framework of a single method, all the activation processes parameters were calculated: Gibbs energy, enthalpy, entropy and volume for both the process of electroneutral vacancy formation and for the process of atom self-diffusion. The isobaric temperature dependences of the indicated activation parameters for BCC and FCC iron structures from T = 10 K to 1810 K along two isobars: P = 0 and 10 GPa were calculated. It is shown that at the α-γ transition temperature (1184 K), the activation parameters decrease during the isobaric transition from the BCC to the FCC structure. At the γ-δ transition temperature (1667 K), the activation parameters increase during the transition from the FCC to the BCC structure. With increasing pressure, the jumps magnitude for the Gibbs energy and the enthalpy of the activation process increases, and for the entropy and volume of the activation process decreases. It is shown that, at low temperatures, due to quantum regularities, activation parameters strongly depend on temperature, and the entropy of activation processes in this region is negative. In the high temperature region, a good agreement has been obtained with the experimental estimates of activation parameters for different iron structures known from the literature.

Comprehensive studies of the physical and mechanical properties and structure of VT1-0 titanium samples processed by selective laser melting have been carried out. High strength characteristics (the ultimate tensile strength of 820 MPa, the yield strength of 710 MPa) have been achieved. These values exceed by 2 times the values for this material produced using conventional technology. The formation of the martensitic αʹ-phase, obtained due to the high crystallization rates realized in selective laser melting process, is the reason for the increase in the mechanical characteristics of titanium VT1-0. Mechanical characteristics of titanium VT1-0 subjected to high-temperature annealing demonstrated a monotonous decrease in strength parameters by 15% and an increase in plastic characteristics by 30%. It is shown that the technology of selective laser melting makes it possible to solve the problem of improving the strength characteristics of unalloyed titanium to create a new class of medical devices.

With a decrease in the thickness of the walls separating the space of pores in porous semiconductors, the potential energy of interaction between an electron and a donor (or a hole and an acceptor) can become greater than the kinetic energy of a free charge carrier. As a consequence, such interlayers lose their conductivity and transit into the dielectric state (Mott phase transition). With regard to the conditions of electrochemical pore formation, this means that as the pore channels approach each other during anodic etching to a distance at which the current flow through the wall that separates them stops, the potential of its surface ceases to be determined by the external electric bias and the electrochemical process, that leads to a further decrease in the thickness of such a wall, stops. Expressions are obtained for the limiting thickness of the walls of pores formed in degenerate semiconductors of n- and p-type conductivity. In contrast to the well-known model that relates the loss of conductivity by pore walls to the combination of space charge layers, the proposed model allows a consistent explanation for the experimental data for both n- and p-type silicon with doping levels above 10^18 cm^-3.

Abstract: We live in a world where large and vast amount of data is collected daily. Analysing such data is an important need. In the modern era of innovation, where there is a large competition to be better then everyone, the business strategy needs to be according to the modern conditions. The business done today runs on the basis of innovative ideas as there are large number of potential customers who are confounded to what to buy and what not to buy. The companies doing the business are also not able to diagnose the target potential customers. This is where the machine learning comes into picture, the various algorithms are applied to identify the hidden patterns in the data for better decision making. The concept of which customer segment to target is done using the customer segmentation process using the clustering technique. In this paper, the clustering algorithm used is Kmeans algorithm which is the partitioning algorithm, to segment the customers according to the similar characteristics. To determine the optimal clusters, elbow methodis used.

and efficient way has always been the focus of researchers. Here, we
reported a high-performance RTP platform based on hydrogen-bonded
organic frameworks (HOFs), by simply and efficiently in-situ
encapsulating phosphor into HOFs materials, the obtained host guest
materials based on HOFs not only exhibited a phosphorescent lifetime of
up to 4.91 ms, but also resisted water and oxygen quenching agents to
maintain phosphorescence in aqueous solution. Besides, attractive
triplet-to-singlet Förster resonance energy transfer (TS-FRET) platform
could be easily fabricated by embedding acceptor into the HOFs-based
host guest materials. Furthermore, the proposed HOFs-based RTP materials
could be facilely processed into luminescent film. Such HOFs-based RTP
strategy are expected to act as a facile and versatile strategy to
prepare outstanding RTP materials.
Is “additional cut” effective for positive margin in cervical conization? It varies with doctors: a retrospective study
Authors: Sun Yujie , He Yingying , Hua Zhengyu , Sun Zhigang , Jiang Nan , Kong Fandou , Xiao Zhen
Published: January 2023

Objective: We aimed at discussing additional cuts, a common problem in
cervical conization. Whether the doctor’s choice of additional cuts in
conization surgery could reduce the occurrence of positive cone margin.
Design: A retrospective study. Setting: First Affiliated Hospital of
Dalian Medical University (Dalian, China). Population: 965 patients
underwent cervical conization. Methods: Statistical analysis of
patients’ pathological reports. Main outcome measures: The age,
preoperative pathology, pathological results of conization, whether or
not to make additional cuts, cone depth and cone volume were studied.
Result: Of the 965 patients included, age, pathology result of
conization, whether to make additional cuts, cone depth and cone volume,
there were significant difference between positive and negative cone
groups. Next, the Multivariable logistic regression analysis suggested
that older age (OR,1.036; 95%CI, 1.017 to 1.054; p<0.001),
the pathology result of conization was HSIL or cervical cancer
(OR,13.203; 95%CI,6.024 to 28.936; p<0.001), additional cuts
(OR, 2.480; 95%CI 1.608 to 3.826; p=0.01) and smaller cone depth (OR,
0.591; 95%CI, 0.362 to 0.965, p=0.036), these factors were the
independent risk for the positive margin group. Conclusions: A certain
proportion of additional cuts can be effectively excised the positive
margin that cannot be cut in the initial conization. Moreover, choosing
the appropriate cone size can maintain a low positive margin rate
without additional cuts. Keywords: Additional cuts; Cone depth; Cone

Published: January 2023

Abstract Aim: Blood pressure-lowering treatment is beneficial for
preventing cardiovascular disease risk among elderly patients. However,
the most appropriate BP targets for elderly patients are controversial.
Methods: We extracted the individual-level data of participants over 60
years from the SPRINT study and ACCORD study first and then conducted a
meta-analysis of major adverse cardiovascular events (MACEs) and adverse
events (hypotension and syncope) and renal outcomes across the SPRINT,
STEP, and ACCORD BP trials, which included 18,806 participants over 60.
Participants were randomized to receive standard BP treatment or
intensive BP treatment. Results: In this meta-analysis, intensive
treatment exhibited a nominal trend toward decreases in all-cause death
(hazard ratio [HR]: 0.98; 95% confidence interval [CI]:
0.76-1.26; p=0.87) and cardiovascular mortality (HR: 0.77; 95%CI:
0.54-1.08; p=0.13). The incidence of MACEs (HR: 0.83; 95%CI: 0.74-0.94;
p=0.003) and stroke (HR: 0.70; 95% CI: 0.56-0.88; p=0.002) was reduced.
Intensive treatment had an inconspicuous effect on coronary disease (HR:
0.87; 95% CI: 0.69-1.10; p=0.24) and heart failure (HR: 0.70; 95%CI:
0.40-1.22; p=0.21). Intensive treatment increased the risk of
hypotension (HR: 1.46; 95%CI: 1.12-1.91; p=0.006) and syncope (HR:
1.43; 95%CI: 1.06-1.93; p=0.02). Intensive treatment did not increase
the risk of either impaired kidney function among patients with chronic
kidney disease (CKD) (HR: 0.98; 95% CI: 0.41-2.34; p=0.96) or without
CKD (HR: 1.77; 95%CI: 0.48-6.56; p=0.40) at baseline. Conclusions:
Intensive BP goals reduced the incidence of MACEs and increased the risk
of adverse events without significant mortality or renal outcome
changes.

(both structural and functional) on the postnatal outcome has been
controversial in literature for decade. Our objective was to evaluate
the role of fetal echocardiography (FE) as a diagnostic tool for early
detection of fetal cardiac abnormalities and its appropriate management
plan. Results: This is a cross-sectional analytical and descriptive
study that included 4366 singleton pregnant women (4366 fetuses)
referred for FE from 2014 to 2022. Indications for referral and
perinatal risk factors were documented. FE and postnatal transthoracic
echocardiography were done. Maximum number of fetal echo done for the
indication of presence of ICEF (1538, 35.2%). Routine FE done in 1199
(27.5%) individual. In 501(11.5%) individual had bad obstetric
history. Fetal cardiac abnormalities were detected in 175 fetuses (4%).
CHDs in 149 (3.4%), fetal arrhythmia in 17 (0.4%)cardiomyopathy in 3
(0.07%) fetuses and cardiac mass (Rhabdomyoma) in 6 fetuses (0.14%).
Of the structural CHDs, maximum number of cases were large VSD, found in
24 (13.7%) cases, Four cases with tiny muscular ventricular septal
defects and two cases with coarctation of aorta, one case of TGA with
IVS and one case of large VSD were missed by FE and were diagnosed
postnatal. Six cases of critical congenital heart disease were underwent
early lifesaving neonatal intervention. Conclusions: FE can accurately
diagnose most of the cardiac anomalies though few errors remain
challenging (aortic coarctation). It also offers a good chance for
successful early life saving management of some types of cardiac
lesions.

Objective: The study was conducted to know the impact of COVID-19
vaccination on menstrual cycle patterns, pre- and post-menstrual
symptoms in women aged 18-45 years. Design & Setting: Multicentric
observational study conducted in six institutes of national importance
in different states of India over one year. Population: A total of 5709
female participants fulfilling inclusion criteria were enrolled.
Methods: Data about impact of vaccines (COVISHIELD and COVAXIN) and
prior COVID-19 infection on menstrual cycle and its associated symptoms
were obtained using an online and offline survey. Main Outcome: COVID-19
vaccination with COVISHILED/COVAXIN resulted in menstrual cycle
disturbances. Results: Of 5709 participants, 78.2% received COVISHIELD,
21.8% COVAXIN. Of all, 333(5.8%) developed post-vaccination menstrual
disturbances with 32.7% frequent cycles, 63.7% prolonged cycles, and
3.6% inter-menstrual bleed. 301 participants, noticed changes in the
amount of bleeding, with 50.2% excessive, 48.8% scanty, and 0.99%
amenorrhea followed by heavy bleeding. Furthermore, the irregularities
of menstrual cycle (p=0.011) and length (0.001) were significantly
higher in the COVAXIN group (7.2%) as compared to COVISHIELD (5.3%). A
total of 721 participants complained of newly developed/worsening pre-
and post-menstrual symptoms. These symptoms were significantly higher in
COVISHIELD group (p=0.031) with generalized weakness and body pains as
main complaints (p=0.001). No significant difference was observed in
COVID-19 infection incidence with these vaccines. When comparing
menstrual abnormalities among those with COVID-19 infection, no
significant associations were observed (p >0.05).
Conclusions: COVISHILED and COVAXIN resulted in menstrual cycle
disturbances and pre-and post-menstrual symptoms. The menstrual
irregularities were significantly higher with COVAXIN vaccine.
On the inverse problem for one-dimensional Burgers' equation from the interior observation
Authors: Oanh Nguyen Thi Ngoc
Published: January 2023

In this work, we study the inverse problem of finding the initial
condition for one-dimensional Burgers’ equation from the interior
observation. Using the variational method, the inverse problem is
reformulated as a optimal control problem. The necessary optimality
condition will be calculated. We also use the conjugate gradient method
to find the minimum of objective functional.

Background: Intrapartum decision-making for women with a previous
caesarean section (CS) is complex due to competing risks of trial of
labour after cesarean (TOLAC) and elective repeat CS (ERCS). Objective:
Determine rates of TOLAC and vaginal birth after cesarean (VBAC) in
sub-Saharan Africa (SSA) and estimate rates of adverse events associated
with TOLAC versus ERCS. Search Strategy: We searched PubMed, MEDLINE,
CAB, EMBASE, and African-specific databases. Selection Criteria: We
included studies with at least one previous CS conducted in SSA. Data
Collection and Analysis: We extracted data on study design, planned and
actual delivery mode, and maternal and perinatal outcomes. We calculated
median TOLAC and VBAC rates pooled mean uterine rupture rate and
compared uterine rupture rates and mortality between TOLAC and ERCS.
Main Results: From 51 included studies, the median TOLAC and VBAC rates,
weighted for sample size, were 75% (IQR: 40-100%) and 34% (IQR:
24-44%) , respectively; and the weighted mean uterine rupture rate was
1.3% (SD: 1.6%). The uterine rupture rate [1.2% vs 0.2%, OR 1.54
(95% CI 0.63-3.75)] and maternal mortality [0.3% vs
<0.1%, OR 0.77 (95% CI 0.30-1.98)] did not differ
significantly between TOLAC and ERCS groups, respectively, however
perinatal mortality was higher for the TOLAC group (5% vs 1%, OR 3.3 ;
95% CI 1.5-6.9) Conclusions: We found high rates of TOLAC and moderate
rates of VBAC across SSA, with a perinatal but no maternal benefit to
ERCS compared to TOLAC. Further research is needed to understand
delivery outcomes in this population of women.

Carnivores participate in forest disturbance recovery by dispersing the
seeds that pass through their digestive systems. The objective of this
study was to evaluate the capacity of mammals for Juniperus deppeana
seed dispersal with an experimental evaluation of endozoochory and
diploendozoochory, through indices of recovery, viability, changes in
testas, and retention of seeds in the digestive tract. Juniperus
deppeana fruits were collected in the Sierra Fría Natural Protected
Area, Aguascalientes, Mexico, and were administered in the diet of gray
fox (Urocyon cinereoargenteus), coati (Nasua narica) and domestic
rabbits (Oryctolagus cuniculus) these three mammals represented the
endozoochory. For the diploendozoochory, seeds excreted by rabbits were
incorporated into the diets of bobcat (Lynx rufus) and cougar (Puma
concolor) in a local zoo. The seeds present in the scats were collected,
and recovery rates and retention times were estimated; viability was
estimated by X-ray optical densitometry, and testa thicknesses and
surfaces were checked by scanning electron microscopy. The results
showed a recovery of seeds greater than 70% in all the animals; the
retention time was < 24 h in the endozoochory, but the time
was longer (24-96 h) in the diploendozoochory (P < 0.05). Seed
viability (x~̵̅ ± SD) was decreased in rabbits (74.0 ± 11.5 %) compared
to fruits obtained directly from the canopy (89.7 ± 2.0 %), while gray
fox, coati, bobcat and puma did not affect viability (P <
0.05). An increase in the thickness of the testas was also observed in
seeds excreted from all mammals (P < 0.05). Through
evaluation, our results suggest that mammalian endozoochory and
diploendozoochory contribute to dispersal of J. deppeana by maintaining
viable seeds with adaptive characteristics in the testa to promote
resilience and forest restoration. In particular, felines (predators)
can provide an ecosystem service through scarification and seed
dispersal.

Published: January 2023

The beetroot leather with CMC (Carboxyl Methyl Cellulose) or carrageenan as a binder resulted in beetroot leather with a dense clay texture and a good level of plasticity. Based on the benefits and content of beetroot and the addition of CMC and carrageenan, this research tries to characterize beetroot leather's physicochemical and organoleptic characteristics from various concentrations and types of thickening agents. This study was arranged in RBD (Randomized Block Design) with 6 treatments and 4 repetitions. CMC was expressed as factor X and carrageenan as factor Y with each concentration level (0.1%; 0.3%; 0.5%). Beetroot leather was tested physically, chemically, shelf life, and organoleptically. Physical tests include color and texture tests. Chemical tests include moisture, ash, antioxidant capacity, and total sugar. The data from observing physical and chemical properties were processed using the ANOVA (Analysis of Variance) method, further tested using DMRT (α=5%) and organoleptic using the Likert scale. The best treatment was found in X1Y1 (CMC 0.1%), which has good physicochemical content with a hardness level of 173.13g, deformation 2.07mm, dark purplish gray color, moisture content 15.72%, ash content 5.23%, total sugar 67.82%, and antioxidants 42.06%. Beetroot leather is easy to consume and has the best hardness level with a moisture content that is not too high, so it is not easily damaged. The organoleptic test showed that the respondents could not distinguish the five treatments and expressed their liking for all beetroot leather products.Keywords:  Beetroot leather, CMC, Carrageenan, Characterization, Organoleptic

The konjac plant (Amorphophallus oncophyllus Prain.) contains high glucomannan with many benefits.  This experiment aimed to study effect of paclobutrazol dose and seedling size on the growth and yield of konjac plants.  The research was arranged factorially based on a Completely Randomized Design with two factor.  The first factor (paclobutrazol dose) consisted of P0: 0.0 g/plant, P1: 0.05 g/plant, P2: 0.10 g/plant, P3: 0.15 g/plant, P4: 0.20 g/plant.  The second factor (seed size) consisted of U1: 20-50 g/seed, U2: 100-150 g/seed, U3: 200-250 g/seed. Observation parameters included plant height, canopy diameter, stem diameter, stem sturdiness, number of buds, weight and diameter of tubers.  Results showed that paclobutrazol dose of 0.20 g/plant had a significant effect on stem sturdiness, weight and diameter of the tubers. The maximum of tuber weight obtained by paclobutrazol application of 0.2 g/plant was estimated to be 1,533 g with tuber diameter of 167 mm.  Small size seed (20-50 g) produced the largest number of buds and did not differ markedly from those of medium size seed (100-150 g).  Large size seed (200-250 g) produced the best konjac plants in term of canopy diameter, stem sturdiness, weight and diameter of tubers. Keywords : Dosage, Konjac, Paclobutrazol, Seed Size, Tuber Size

Published: January 2023

One of the processed products derived from coconut that has great demand in the world of health and beauty industry is virgin coconut oil or known as VCO. Most VCO is processed manually using conventional methods with unhygienic plastic containers and placement in open spaces by the home industries. This research is to develop a VCO-fermented tank that was able to maintain hygiene and low temperature during the fermentation process by using SS403 and teak wood insulation as the main materials. This research carries on by comparing the fermentation process and results between the conventional method and the new VCO tank. 41% VCO is produced from raw coconut milk using a new VCO tank which is 5% higher than the conventional method. The VCO fermented tank produced more VCO and was able to maintain lower temperatures compared to the conventional method and also can be operated with less procedure order.     Keywords: Fermentation Tank, Temperature Retaine, VCO, Virgin Coconut Oil
