Authors: Abiola Yusuf Abubakar
Published: February 2022

The study examined quality assurance parameters as predictors of teachers’ motivation in public junior secondary schools in Kwara State. The study adopted the descriptive survey research design of correlation type. The population for this study comprised 5149 teachers of public junior secondary schools in Kwara State. The sample comprised of 640 teachers selected using the multistage sampling technique. A self-developed and validated research instrument titled “Quality Assurance Parameters and Motivation Questionnaire” (QAPMQ) was used to collect information with a reliability coefficient of 0.85. The result showed that teachers in public junior secondary schools in Kwara State had a moderate level of motivation (52.3%). The further showed that quality assurance parameters are significant predictors of teachers’ motivation (72.6% (Adj. R2= 0.726); and each of the quality assurance parameters of human resource maintenance (Beta= 0.704, t= 25.132) and data management (Beta= 0.366, t= 13.101) had significant predictions to teachers’ motivation, while funding was not significant (Beta= -0.275, t= -9.638) in Kwara State public junior secondary schools. Therefore, it was recommended that Kwara State government should not relent its efforts and continue to work collaboratively with Non-Governmental Organizations (NGOs), philanthropists, and other stakeholders in the education sector to ensure its assurance parameters are continued and appropriately used in stimulating teachers’ motivation in the State public secondary schools.
Droseraceae gland and germination patterns revisited: support for recent molecular phylogenetic studies
Authors: Conran John G. , Jaudzems Gunta , Hallam Neil D.
Published: February 2022

Droseraceae germination and leaf gland and microgland character state patterns were re-examined in the light of new molecular phylogenetic relationships. Phanerocotylar germination is basal in the family, with cryptocotylar germination having evolved at least twice; once in Aldrovanda, and again in Drosera within the Bryastrum/Ergaleium clade. Gland patterns also support major clades; with the Bryastrum clade taxa having marginal and Rorella-type glands whereas the terminal branch of the Drosera clade had marginal glands and most of the clade possessed biseriate type 3 glands. The gland and germination patterns are supported by growth habit features, suggesting that the family and the main clades within Drosera in particular have undergone major adaptive radiations for these characters.

1806, year of birth of the 'cruel' Pinguicula crystallina Sm. (Lentibulariaceae). To the memory of 200 years Florae Graecae Prodromus (1806-1816) and Flora Graeca (1806-1840)
Authors: Casper S. Jost
Published: February 2022

Since its discovery, Pinguicula crystallina Sm. has deeply impressed botanists and friends of flowering plants at every turn. It was discovered in 1787 by John Sibthorp and Ferdinand Bauer in the Troodos mountains of Cyprus, but this tiny carnivorous herb first became known to the scientific botanical community in 1806, with the publications of the famous Florae Graecae Prodromus and Flora Graeca. In 1914, Holmboe called it 'the most typical species and also the greatest ornament of the vegetation in the springs.'

Pinguicula vulgaris L. in the Champagne state of France: life in an alkaline bog
Authors: Legendre Laurent , Cieslak Thomas
Published: February 2022

Pinguicula vulgaris was observed growing in the Champagne state of France near the city of Rheims during 1994-2000. The plants are the remnants of what was, up to the beginning of the 20th century, a largely distributed set of populations that grew all over the Champagne and Paris basins. During the time of the study, the three populations were living in alkaline bogs and were gradually reducing in size. The plants differed from most other P. vulgaris by their ability to generate large numbers of gemmae in the winter, the round shape of their seed capsules and the small size of their leaf rosettes. A rough description of their habitat is presented in this article to explain their survival and observed dwindling numbers.
Reassessing commensal-enabled carnivory in Proboscidea and Ibicella?
Authors: Rice Barry
Published: February 2022

In 1999 I conducted experiments to look for enzymatic activity on the glandular leaves of Ibicella lutea (Pedaliaceae), also known as the devil’s claw or unicorn plant. I saw no evidence for enzymes, inferred the plants were not carnivorous, and wrote that “These are interesting plants, but I have no room for them in my carnivorous garden. The seeds I will send to the ICPS seed bank will be my last”. Furthermore, on my web site I wrote that “…on the whole, I have lost interest in this non-carnivore” (Rice 2004). Ah, how presumptuous I was.
Survival of dried turions of aquatic plants
Authors: Adamec Lubomir
Published: February 2022

Aquatic carnivorous plants in the genera Aldrovanda and Utricularia produce turions: dormant, overwintering buds modified into storage organs. Turions are durable, partly frost-tolerant organs which usually overwinter in shallow water close to the bottom, below ice cover. However, in some species turions overwinter also above the water surface in the terrestrial ecophase, on wet organic soil.
Taxonomic Relationships of Some Sarracenia spp. (Sarraceniaceae) are not Deducible Based on Palynology
Authors: Bodri Michael S. , Sinn Robert
Published: February 2022

Pollen morphometrics for Sarracenia alata, S. flava, S. minor, S. purpurea and S. rubra were determined in an effort to utilize polar and equatorial dimensions to help determine species relationships. Although Sarracenia flava was found to be distinct from the other species, which in themselves form a distinct group, this study found that pollen morphometrics do not allow greater distinction between species. Therefore, pollen measurements are not valid in determining phylogenetic relationships for the genus.

The Bako National Park (Taman Negara Bako) was founded in 1957, making it the oldest national park in Sarawak. It covers an area of 2.727 ha (6.738 acres) at the tip of the Muara Tebas Peninsula. This rather small national park is familiar to many carnivorous plant enthusiasts due to the various species of Nepenthes that grow within it, and its close proximity to Kuching, the state capital.
Soil fertilization of Sarracenia seedlings
Authors: Brittnacher John
Published: February 2022

Conventional wisdom has it that soil fertilization is dangerous for carnivorous plants. A grower may get away with it once or twice with great results but the next time wipe out their whole collection. I have seen this on a small scale with volunteers at the University of California, Davis, Botanical Conservatory multiple times. At first the plants are truly stunning. Give them one treatment too many or at the wrong time and all the plants die. We are talking hundreds of plants.
The folklore of man-eating plants
Authors: Villari Joseph
Published: February 2022

Stories and tales of man-eaters seep from every continent on earth. They instantly conjure up feelings of fascination, adventure, and terror. Too frequently these events are over-sensationalized and told with a journalistic (shall we say “attention-grabbing”) slant. The stories usually portray the accused man-eater as some horrible beast, and the men being eaten as innocent, helpless victims. This is mostly far from the truth; most occurrences of predation on people are caused or instigated by the people who are attacked. In fact most animals labeled with the unfortunate moniker of man-eater are quite innocent of that accusation. But, what if this accused man-eater is a plant!
Comparative studies on the acid proteinase activities in the digestive fluids of Nepenthes, Cephalotus, Dionaea, and Drosera

Published: February 2022

There are various kinds of carnivorous plants in nature, and most of them excrete acidic digestive fluids which contain digestive enzymes, especially acidic proteinases, to digest trapped insects and other prey for nutrition. Previous inhibitor studies indicated that the acid proteinase nepenthesin from Nepenthes belongs to the aspartic proteinase family. Recently, we purified two nepenthesins from the digestive fluid of N. distillatoria, investigated their molecular and enzymatic properties, and elucidated their primary structures by cDNA cloning of nepenthesins from N. gracilis.
Photosynthetic CO2 affinity of aquatic carnivorous plants growing under nearly-natural conditions and in vitro
Authors: Adamec Lubomir , Pasek Kamil
Published: February 2022

Net photosynthetic rate of aquatic carnivorous plants in standing waters can sometimes be limited by low concentration of free CO2. As net photosynthetic rate of terrestrial plants growing in vitro is greatly reduced, as compared to the same plants grown naturally, it could be assumed that photosynthetic CO2 affinity in aquatic carnivorous plants growing in vitro will be reduced. The aim of this study was to compare values of CO2 compensation point of photosynthesis in several strains of Aldrovanda vesiculosa and in 13 aquatic Utricularia species, both in plants growing under nearly-natural conditions in containers or aquaria and in vitro. The dependence of CO2 compensation point on growth conditions is discussed.

Authors: Howlett Michael
Published: February 2022

The Watson Pinelands Preserve is a 4.8-ha (12-ac) privately owned facility nestled in the Big Thicket of east Texas, and is home to many species of carnivorous plants. Development and maintenance of the preserve as a living record of the rich diversity of East Texas herbaceous and woody plants has not been an easy task, and has had its share of conservation issues as well. This article will discuss some of the many conservation issues that affect the Watson Pinelands Preserve, and what can be done to reduce and/or eliminate some of these effects.
Turion development is an ecological trait in all populations of the aquatic carnivorous plant Aldrovanda vesiculosa (Droseraceae)
Authors: Cross Adam T.
Published: February 2022

Aldrovanda vesiculosa L. is a globally rare aquatic carnivorous plant, recently listed as Endangered by the International Union for the Conservation of Nature (IUCN) in light of significant population decline worldwide over the last century. Fewer than 50 extant natural populations are now believed to exist worldwide. However, despite the recent focus afforded to the species in the face of its decline, several aspects of its ecology and biology remain unclear. As part of a concerted global effort to conserve, restore, and increase awareness of the threats faced by A. vesiculosa, this paper discusses population differentiation in the context of coloration and the production of turions (hibernacula).
A short history of an exotic carnivorous planting in New Jersey, USA
Authors: Rice Barry , Bockowski Jim
Published: February 2022

More than thirty years ago, a few non-native carnivorous plants were introduced into a prime wetland in New Jersey. We provide a candid description of the events that followed, and the current state of affairs at this site. While it is now widely understood that such introductions of non-native plants into wildland areas are generally unwise, back then this knowledge was not so widespread. This paper is not intended to debate the merits or dangers of introducing non-native plants, nor is it intended as an exercise in laying blame. It is hoped, however, that future botanists encountering this site might find this paper illuminating and clarifying.

Published: February 2022

Considering the scarcity of studies on the nutrients and phenolic compounds in the wasted fractions of the pequi (Caryocar brasiliense Camb.) fruit processing, this study investigated the proximate composition, identified the phenolic compounds, and quantified the gallic and ellagic acids in the shell (peel and external mesocarp), and in the external mesocarp of pequi. The shell and the external mesocarp of the pequi fruit presented high concentrations of total dietary fibers, soluble fibers and phenolic compounds, mostly the freeze-dried pequi shell, which showed approximately 50% total dietary fibers, 20% soluble dietary fibers and 10% polyphenols, with remarkable antioxidant capacity. The phenolics identified in the pequi shell and external mesocarp were gallic acid, ellagic acid, and quercetin. In addition, protocatechuic acid, catechin, p-coumaric acid, and luteolin were identified for the first time in the pequi by-products. The freeze-dried pequi shell showed twice the gallic and ellagic acids concentrations compared to those of the external mesocarp. The wasted by-products of pequi, especially the pequi shell, are rich in healthy phytochemicals with the potential to be used by the food and pharmaceutical industries as ingredients in functional plant-based products or nutraceuticals.

Authors: Yunus Mohd
Published: February 2022

Persepsi para pihak merupakan elemen kunci untuk mewujudkan pengelolaan DAS Kampar yang berkelanjutan. Kajian ini memiliki tujuan mengidentifikasi permasalahan hidrologi berdasarkan persepsi para pihak dan mengidentifikasi kesenjangan antara persepsi tersebut. Kajian ini telah dilaksanakan pada bulan September 2018 - April 2019 di Provinsi Riau dan Provinsi Sumatera Barat. Metode analisis yang digunakan adalah analisis deskriptif, meliputi proses editing data, kategorisasi, dan penafsiran data. Permasalahan hidrologi yang selama ini sering terjadi menurut masyarakat adalah pencemaran, banjir, erosi, abrasi, kekeruhan, dan pendangkalan. Faktor penyebab permasalahan hidrologi meliputi penggunaan pelet dari keramba jaring apung (KJA), limbah kelapa sawit, dan pembukaan lahan yang masif, penebangan liar di bagian hulu dan penambangan batu sungai. Persepsi umum dari pemerintah menegaskan bahwa dalam beberapa tahun terakhir ini, kualitas air Sungai Kampar semakin memburuk. Hal tersebut disebabkan oleh beberapa hal, meliputi maraknya penebangan hutan, pembangunan yang bersifat parsial dan sektoral, belum tersedianya perencanaan pengembangan sumber-sumber air yang menyeluruh dan terpadu yang mencakup aspek pemanfaatan, pengelolaan, serta pengendalian dan pelestarian. Secara umum, persepsi para pihak memiliki persamaan. Walaupun begitu, masih terdapat beberapa perbedaan.

Published: February 2022

BACKGROUND: Brooklyn Chest Hospital (BCH) is a specialised TB hospital in Cape Town, South Africa. We describe reasons for admission, patient profiles and hospital-discharge outcomes in children admitted to BCH. This was compared to a previous study (2000–2001).METHODS:
This retrospective, descriptive study included all children (0–14 years) admitted to BCH from January 2016 to December 2017. Data collected from patient folders and a laboratory database included demographic data, reasons for admission, clinical data and hospital outcomes.RESULTS:
Of 263 children admitted, 133 (50.6%) were male. The median age was 32 months (IQR 15–75); 48 (18.3%) were HIV-positive and 150 (57.0%) had bacteriologically confirmed TB. Reasons for admission included social/caregiver-related (n = 119, 45.2%), drug-resistant TB (n = 114,
43.3%), TB meningitis (n = 86, 32.7%) and other severe types of TB (n = 63, 24.0%); 110 (41.8%) children had >1 reason for admission. TB meningitis admissions decreased (P = 0.014) and those for drug-resistant TB increased (P < 0.001) compared to 2000–2001.
Pulmonary TB was diagnosed in 234 (89.0%), extrapulmonary TB in 149 (56.7%) and 126 (47.9%) had both. At discharge, 73 (27.8%) had completed treatment, 182 (69.2%) were transferred out to complete treatment at community clinics, and 6 (2.3%) died.CONCLUSIONS: Although most children
were admitted for clinical reasons, social/caregiver-related reasons were also important.

nucleotide polymorphism (SNP) array
Authors: Pastorczak Agata , Urbańska Zuzanna
Published: February 2022

Genetic abnormalities detected in the leukemic genome became essential
prognostic factors stratifying the intensity of treatment in children
with acute lymphoblastic leukemia (ALL). However, only selected copy
number alterations are independently associated with the clinical course
of disease. Deletions within the IKZF1 gene significantly confer to poor dzieprognosis
of ALL, particularly when cooccurred with deletions of CDKN2A/
B, PAX5, and genes from PAR1 region and the concomitant lack of
ERG gene deletion is present. In the project, high-density SNP array were
tested on 195 childhood BCP-ALL samples to optimize the detection of
copy number alterations within selected gene loci. Developed experimental
protocol and data analysis enabled identification of clonal and
mosaic forms of IKZF1 deletions.

In this paper, preliminary design study of Gas Cooled Fas Reactors with Natural Uranium as Fuel Cycle Input has been performed. Gas Cooled Fast Reactor is slightly modified by employing modified CANDLE burnup scheme so that it can use Natural Uranium as fuel cycle input. The natural uranium is initially put in region 1, after one cycle of 10 years of burn-up it is shifted to region 2 and the region 1 is filled by fresh natural uranium fuel. This concept is basically applied to all regions. In this case the system has been applied to many power level which results relatively flexible discharge burn-up level up from about 20%HM to 30 %HM.
Study of Transuranium Recycling in PWR with 3-D Burnup Analysis using SRAC-COREBN Code
Authors: Waris Abdul , Rahmanto T. , Taufiq Imam , Kurniadi Rizal , Su’ud Zaki
Published: February 2022

In the light of proliferation resistance and terrorism issues several nuclear energy authorities and experts have suggested not to separate plutonium and minor actinides during the nuclear spent fuel reprocessing. Along the lines of this recommendation, a study of transuranium recycling in pressurized water reactor (PWR) with 3 dimensional burnup analysis by using SRAC-COREBN code has been carried out. The results show that by recycling of 8%, 10%, and 12 % of plutonium and minor actinides in PWR, the necessary uranium enrichment in loaded enriched uranium fuel of each scenario can be reduced to 2.7%, 1.52%, and 1.32%, correspondingly. In addition to this, the amount of loaded uranium fuel diminishes considerably with the increasing of the amount of recycled of plutonium and minor actinides.
Effect of Voltage Bias at MEH-PPV Layer on SPR Wavelength observed during in-situ Measurement Method in Polymer Light Emitting Diode
Authors: Hendro Hendro , Djamal Mitra , Hidayat Rahmat , Kurnia Daniel , Buchari Buchari
Published: February 2022

The shifting of surface plasmon resonance (SPR) wavelength has been observed during in situ measurement in polymer light emitting diode (pLED). Examination is performed using an pLED sample which has an ITO/PEDOT:PSS/MEH-PPV/Au structure. When the voltage bias is increased from 0 to 9 volt the SPR wavelength shifts from 612 nm to 628 nm and the absorption curve shifts to lower absorbance value. From the theoretical analysis, it can be understood that the change of the SPR dip and the absorption curves correspond to the change of dielectric constant of the MEH-PPV layer. These results show that SPR wavelength depends on the metal and air dielectric constant as well as on the MEH-PPV layer. These results also imply that the SPR wavelength being evaluated can be controlled by varying the voltage bias.

Authors: Mustopa Enjang Jaenal , Srigutomo Wahyu , Sutarno Doddy , Fauzi Umar
Published: February 2022

Controlled-source audio frequency magnetotelluric (CSAMT) survey consisting of 60 soundings has been carried out in the Kamojang geothermal field to delineate resistivity structure correlated to the present geothermal reservoir. The transmitter site was located about 3 − 5 km in the south-west of the survey area. The sounding sites were distributed irregularly and the distance between each of them varied from 200 to 500 m, covering the Kamojang Geothermal area. The two dimensional (2D) inversion scheme was applied to interpret the CSAMT data. The results show that the subsurface resistivity structures in the Kamojang geothermal field consists of three types of resistivity features correlated to the existing geothermal reservoir in the area, that is, the overburden (first layer) having resistivity value of 30 – 150 ohm.m and thickness of 30 to 100 m overlaying the intermediate (second) layer which has an extremely low resistivity of 3 – 10 ohm.m with 500 – 1200 m thick. This low resistivity layer can be considered as a hydrothermal alteration zone comprising the impermeable layer or sealing cap rock. Finally, the third layer which is relatively more resistive than the second layer with resistivity of 30 − 100 ohm-m. From the 3D view of the low resistivity anomaly (<10 ohm.m) considered as a hydrothermal alteration zone, it is obtained that altered zone is deep in the south-west and becomes shallow in the north-east of the area.

By applying a constant pressure gradient, volumetric flux was determined as a function of time until a steady condition is achieved. For steady laminar flow, its velocity profile is parabolic. For flow in porous media between two stationary parallel plates, the results show that medium permeability depends on porosity and obstacle configurations. For a single obstacle, the permeability is a parabolic function with respect to positions of an obstacle in the direction perpendicular to the flow. The permeability is smallest when the obstacle is at the central line along the flow. A maximum permeability may be achieved when the obstacles attached to the channel wall. Other obstacle structures give lower permeability, even zero permeability for dead end microchannels.

An investigated process of recycling option based on minor actinide (MA) composition in the reactor design has been investigated which is based on fast breeder reactor (FBR) type as reference reactor type. The paper investigated some significant parameters of reactor operation, fuel sustainability and nuclear non-proliferation point of view. As initial fuel composition some composition of light water reactor (LWR) spent fuels are used and loaded into the such as mixed oxide (MOX) in the core regions and minor actinide doping is loaded into blanket regions. It is shows that criticality condition as indicating reactor operation time is obtained less for loading MA case in the blanket regions in comparing with no loading MA. It indicates a shorter reactor operation time is obtained for loading MA than without loading MA. Conversion rasio level or breeding rasio, is obtained less conversion rasio for loading MA which shows less fissile material production when some portion of U-238 is replaced by MA loading. Although, during reactor operation, some fissile plutonium materials such as Pu-239 are also produced from MA loading, however, it still less production in comparing with fissile plutonium production from direct process from converted U-238. It shows more Pu-238 can be produced than Pu-240 because of main portion of MA is Np-237 which can be directly produce more Pu-238 than Pu- 240. As protected plutonium composition (Pu-238 and Pu-240), loading MA produces some even mass plutonium isotopes in the blanket regions and loading 5 % of MA doping, obtains more than enough composition based on Kessler’criterion to estimate the level of technical difficulty for contructing explosive nuclear devices based on internal heating of Pu-238.

Objective: As the associations of sperm DNA fragmentation with morphology have not been examined in detail, this study aimed to investigate the relationship between abnormalities of morphological details and DNA integrity in human sperm.Methods: In this cross-sectional study, men from infertile couples were enrolled at Hue Center for Reproductive Endocrinology and Infertility, Vietnam. Conventional semen parameters, including morphological details, were analyzed following the World Health Organization 2010 criteria. Sperm DNA fragmentation was evaluated using a sperm chromatin dispersion assay. The relationships and correlations between semen parameters, sperm morphology, and the type of halosperm and the DNA fragmentation index (DFI) were analyzed.Results: Among 130 men in infertile couples, statistically significant differences were not found in the sperm halo type between the normal and abnormal sperm morphology groups. The percentage of round-head spermatozoa was higher in the DFI >15% group (16.98%±12.50%) than in the DFI ≤15% group (13.13%±8.82%), higher values for amorphous heads were found in the DFI >15% group, and lower values for tapered heads were observed in the DFI ≤15% group; however, these differences were not statistically significant. Small-halo sperm and the DFI were positively correlated with round-head sperm (r=0.243, p=0.005 and r=0.197, p=0.025, respectively). Conclusion: The rate of general sperm morphological abnormalities in semen analysis was not related to sperm DNA integrity. However, round sperm heads were closely associated with sperm DNA fragmentation.
Comparison of the effects of coenzyme Q10 and Centrum multivitamins on semen parameters, oxidative stress markers, and sperm DNA fragmentation in infertile men with idiopathic oligoasthenospermia
Authors: Alahmar Ahmed T , Singh Rajender
Published: February 2022

Objective: Oxidative stress and sperm DNA fragmentation (SDF) have been linked to idiopathic male infertility (IMI). Various antioxidants have been tried to improve semen parameters and fertility potential in IMI patients, but with inconsistent results. The study aimed to compare the effects of coenzyme Q10 (CoQ10) and Centrum multivitamins on semen parameters, seminal antioxidant capacity, and SDF in infertile men with idiopathic oligoasthenospermia (OA).Methods: This prospective controlled clinical study involved 130 patients with idiopathic OA and 58 fertile controls. The patients were divided randomly into two groups: the first group received CoQ10 (200 mg/day orally) and the second group received Centrum multivitamins (1 tablet/day) for 3 months. Semen parameters, CoQ10 levels, reactive oxygen species (ROS), total antioxidant capacity (TAC), catalase, SDF, and serum hormone levels (follicle-stimulating hormone, luteinizing hormone, testosterone, and prolactin) were compared at baseline and after 3 months. Results: Both CoQ10 and Centrum improved sperm concentration and motility, but the improvement was greater with Centrum therapy (p<0.05). Similarly, both therapies improved antioxidant capacity, but TAC improvement was greater (p<0.01) with CoQ10, whereas ROS (p<0.01) and SDF (p<0.001) improvements were greater with Centrum administration. Centrum therapy was associated with reduced serum testosterone (p<0.05).Conclusion: In conclusion, both CoQ10 and Centrum were effective in improving semen parameters, antioxidant capacity, and SDF, but the improvement was greater with Centrum than with CoQ10. Therefore, Centrum—as a source of combined antioxidants—may provide more effective results than individual antioxidants such as CoQ10 in the treatment of infertile men with idiopathic OA.
Lifetime changes of the oocyte pool: Contributing factors with a focus on ovulatory inflammation

In mammalian species, females are born with a number of oocytes exceeding what they release via ovulation. In humans, an average girl is born with over a thousand times more oocytes than she will ovulate in her lifetime. The reason for having such an excessive number of oocytes in a neonatal female ovary is currently unknown. However, it is well established that the oocyte number decreases throughout the entire lifetime until the ovary loses them all. In this review, data published in the past 80 years were used to assess the current knowledge regarding the changing number of oocytes in humans and mice, as well as the reported factors that contribute to the decline of oocyte numbers. Briefly, a collective estimation indicates that an average girl is born with approximately 600,000 oocytes, which is 2,000 times more than the number of oocytes that she will ovulate in her lifetime. The oocyte number begins to decrease immediately after birth and is reduced to half of the initial number by puberty and almost zero by age 50 years. Multiple factors that are either intrinsic or extrinsic to the ovary contribute to the decline of the oocyte number. The inflammation caused by the ovulatory luteinizing hormone surge is discussed as a potential contributing factor to the decline of the oocyte pool during the reproductive lifespan.
Self- Reported Ancestry and Craniofacial SNPs: Assessing Correspondence with Implications for Forensic Case Analysis and Reporting

Published: February 2022

Genotype-phenotype studies increasingly link single nucleotide polymorphism (SNPs) to the dimensions of the face for presumed homogeneous populations. To appreciate the significance of these findings, it is essential to investigate how these results differ between the genetic and phenotypic profiles of individuals. In prior work, we investigated the connection between SNPs previously iden-tified as informative of soft tissue expression and measurements of the craniofacial skeleton. Using matched genetic and skeletal informa-tion on 17 individuals who self-identified as White with presumed common continental ancestry (European), we obtained significant Spearman correlations for 11 SNPs. In the present study, we looked at self-identified ancestry to understand the intersectional background of the individual’s phenotype and genotype. We integrated our samples within a diverse dataset of 2,242 modern Americans and applied an unsupervised model-based clustering routine to 13 craniometrics. We generated a mean estimate of 69.65% (±SD = 18%) European ances-try for the White sample under an unsupervised cluster model. We estimated higher quantities of European ancestry, 88.5%–93%, for our subset of 17 individuals. These elevated estimates were of interest with respect to the distribution of population-informative SNPs; we found, for example, that one of our sampled self-identified White individuals displayed SNPs commonly associated with Latin American populations. These results underscore the complex interrelationship between environment and genetics, and the need for continued research into connections between population affinity, social identity, and morphogenetic expression.
A Novel Algorithm-based MPPT Strategy for PV Power Systems under Partial Shading Conditions
Authors: Chiu Chian-Song , Ngo Sy
Published: February 2022

This paper proposes a new simple method based on the simulation of a short-distance running race in athletics to track the maximum power point (MPP) for photovoltaic (PV) power systems, which can improve the tracking speed and search accuracy. In detail, the DC-DC boost converter is utilized to transfer the power of PV panels to a load and follows the MPP all the time, regardless of the environmental temperature and variant solar irradiance. In the MPP search method based on the proposed short-distance running algorithm (SDRA), an appropriate duty ratio value will be found so that the load receives the highest electrical power from the PV energy system. As a result, the SDRA method has excellent MPP tracking ability with high convergence speed and no oscillation. The efficiency of the proposed method is verified by simulation and experiments. The proposed SDRA method overcomes the obstruction of local traps to achieve global MPP. The results have shown that the SDRA method has advantages in terms of better convergence speed and performance than the particle swarm optimization (PSO) and grey wolf algorithm (GWA) methods when they are operated under the same conditions.

Hybrid perovskite thin film offers diverse advantages like low cost deposition techniques, less material consumption and superior optoelectronic properties. These merits including high voltage and high efficiency performance in a wide range of high light intensity are sufficient to distinguish perovskite thin films/devices from their contenders as a thin film technology with greater potential for industrial applications. Perovskite thin film technology demonstrates potency in a variety of applications in optoelectronic devices especially photovoltaic applications. The National Renewable Energy Laboratory (NREL) of the USA categorizes a number of thin films technologies including perovskite thin film, as emerging photovoltaics with the bulk of them yet to be commercially applied but are still in the research or developmental stage. In this chapter, various processing methods and material combinations as well as current trends in this technology are subjects of discussion.
Oxygen and Redox Reactions Contribute to the Protection of Free-Living and Parasite Helminths against Pathogens and/or Host Response
Authors: Plancarte Agustin , Nava Gabriela
Published: February 2022

Millions of years ago, the reductive atmosphere environment of Earth was replaced by an oxidative one because of redox reactions. These conditions allowed aerobic organisms to populate the planet and control the toxicity of oxygen. Aerobic organisms began to produce reactive oxygen species (ROS) via oxygen redox reactions and used them for their physiology process. Free-living helminths appeared in the early Paleozoic era and parasite helminths in the late same era. Free-living helminths, such as Caenorhabditis elegans and earthworms, have been used as host models to understand their micro pathogen defenses, particularly those associated with ROS. We speculate that the micro pathogens of C. elegans are equivalent to the parasite helminth hosts in terms of generating a worm’s defense response. Therefore, parasite helminths may share similar defense mechanisms to humans, as in C. elegans. This last observation suggests the existence of a conservative pathogen protection process for centuries. This review discusses the evolution of oxygen molecules and redox reactions, as well as of the Earth’s atmosphere, and changes over time in the protection of helminths mechanisms. These mechanisms have been so successful that have improved our understanding and have had a positive impact on humans.
