INVESTIGATING THE RELATIONSHIP BETWEEN THE USE OF DOMESTIC RADIO AND THE LEVEL OF SOCIAL TRUST
Authors: Farajian Morteza
Published: February 2022

This study studies the relationship between radio usage and social trust. We have considered trust in three types: interpersonal trust, general and institutional trust. The research method used in this research is the survey method that the research data was collected using a questionnaire in the field. Also, 383 samples were selected and operated by systematic cluster sampling. The results show that there is a significant relationship between radio usage and general trust. But there is no significant relationship between radio usage and institutional trust. The results showed that between the use of radio program significantly affects interpersonal trust. Examining the relationship between the use of different types of radio programs with the intermediate variables of the research shows that there is a significant relationship between the use of radio and the intermediate variables of generalism and the feeling of security. The results showed that there is a significant relationship between research mediating variables and the level of social trust in its types of trust. All research mediating variables have a significant relationship with institutional trust. Finally, it can be stated that the use of radio affects the level of social trust by directly affecting social trust and also by indirectly influencing through research interface variables.

Effectiveness of proprioceptive neuromuscular facilitative stretching combined with administration of Diclofenac compared to proprioceptive neuromuscular facilitative stretching and placebo medication for the treatment of cervical facet syndrome
Authors:   , Upneck Heidi Sian
Published: February 2022

The purpose of this study was to test the Effectiveness of Proprioceptive Neuromuscular Facilitative Stretching combined with administration of Diclofenac compared to Proprioceptive Neuromuscular Facilitative Stretching and placebo medication for the treatment of Cervical Facet Syndrome in a clinical experimental setting. Neck pain is a common disorder, which can often be attributed to mechanical dysfunction of the cervical spine. The patient with facet syndrome may complain of sudden onset of unilateral neck pain, often with referred pain. Muscle spasm is usually present causing restricted movement. Pain increases with movement and is relieved by rest. The pain is aggravated by hyperextension and relieved by flexion and often follows a sclerotomal rather than a dermatomal pattern. Forty subjects with mechanical neck pain were screened for facet syndrome and randomly divided into two groups of twenty. Each patient received Proprioceptive Neuromuscular Facilitative (PNF) stretching of the Posterior Cervical and Trapezius musculature. In conjunction with this, half the patients received Cataflam D while the other half received placebo medication. The patients were treated five times over a period of two weeks. Both groups were evaluated in terms of subjective and objective clinical findings by making use of questionnaires (Numerical Pain Rating Scale 101, Short Form McGill Pain Questionnaire and the CMCC) and algometer and goniometer measurements respectively. The data was collected at the initial, middle and final treatments for each patient.
The relative effectiveness of a conservative multi-method treatment protocol (S.M.T. and Diclofenac) for the management of chronic mechanical thoracic spine pain
Authors:   , Bhoola Nayna Ratilal
Published: February 2022

The aim of this study was to determine the relative effectiveness of the combination of spinal manipulative therapy (SMT) and non-steroidal anti-inflammatory drugs (NSAIDs) versus SMT with the administration of a placebo medication in the treatment of chronic mechanical thoracic facet syndrome. It was hypothesised that SMT and NSAIDs over a three week period would be more effective than SMT and placebo medication in terms of the objective and subjective clinical findings. The study design was that of a double blind randomized clinical trial. Sixty patients diagnosed with thoracic facet syndrome were randomly assigned to either the manipulation and NSAID group or the manipulation and placebo medication group. The age range of the patients was eighteen to fifty-nine years. Each patient in the NSAID group received 139mg of diclofenac free acid per day over five days. The placebo group received the same dosage of a similar appearance to that of diclofenac free acid over the same period. The placebo medication was in the form of lactose powders. Each group of thirty patients received six treatments of SMT over a three-week period. Group A received SMT and placebo medication while Group B received SMT and NSAIDs. The patients were assessed by means of obtaining subjective information consisting of three questionnaires; the McGill Short-Form Pain Questionnaire, the Numerical Pain Rating Scale -lOl and the Oswestry Pain Disability Index. Objective data was gathered from goniometer measurements. The objective data was collected before the
Menopausal syndrome

Published: February 2022

The purpose of the study was to determine the effectiveness of the selected Homoeopathic remedy on the menopausal syndrome in terms of the patients perception of the treatment. It was hypothesized that the Homoeopathic medicine would improve the patients perception of the treatment. Participants were drawn from the greater Durban area. Convenience sampling was used to draw patients into the trial. Volunteers responded to advertisements that had been placed in various advertising media. For acceptance into the trial, the participants were required to have a gynecological examination by a registered gynecologist, to confirm that they were menopausal. Of the participants meeting the above criteria thirty were chosen to participate in the trial. Fifteen constituted the placebo/control group and were given a placebo, and fifteen constituted the treatment group and were given the selected Homoeopathic medicine according to their simillimum. This was a double blind study with the medicine being dispensed on a random basis by a qualified pharmacist in order to eliminate bias. Three participants dropped out in the early stages of the study and were replaced by three other patients. Patient perception was measured by means of questionnaires
The relative effectiveness of spinal manipulation and ultrasound in mechanical neck pain
Authors:   , Moodley Malany
Published: February 2022

The aim of this study was to determine the effectiveness of adjustments versus the use of ultrasound in the treatment of mechanical neck pain. It was hypothesized that treatment with adjustments over a four week period, with a further four week follow-up period, would be more effective than ultrasound in terms of improving patients' cervical ranges of motion and their perceptions of pain and disability. Thirty consecutive patients suffering from mechanical neck pain were randomly assigned to either the adjustment or ultrasound groups. An experimental design was employed, whereby both groups received treatment twice a week for four weeks. After a follow-up period of a month, the patients were re-assessed. Measurements of the cervical spine ranges of motion with the CROM goniometer, algometer readings, and the completion of the Numerical Pain Rating Scale-101, CMCC Neck Disability Index and the Short Form McGill Pain questionnaires were performed before the first, fourth and final treatments as well as at the one month follow-up consultation. The data were then transferred to spreadsheets and underwent statistical analyses, using a 95 % confidence level. Analyses within each group were performed, using the Wilcoxon Signed Rank test and various readings were compared. The reading taken before the first treatment was compared to the reading taken before the final treatment. The initial reading was then again compared with the reading taken at the one month follow-up consultation. Comparison of the results of both treatment groups was statistically evaluated, using the Mann-Whitney U-Test. The comparison was made using the readings of the first, fourth and final treatments, as well as the one month follow-up consultation. This was done for all measurement parameters.
The short term effectiveness of cervical spine manipulation as compared to piroxicam administration in the treatment of chronic cervical facet syndrome
Authors:   , O'Connor Brendan John
Published: February 2022

For neck pain, the first-line treatment of allopathic physicians is usually the prescription on non-steroidal ant-inflammatory drugs (NSAIDs), whereas the firstline treatment of chiropractic physicians is usually cervical manipulation. The literature shows that both chiropractic manipulation alone and NSAIDs alone are effective for the treatment of cervical facet syndrome, with chiropractic manipulation being much safer than the use of NSAIDs. Furthermore, patients that receive chiropractic care have been shown to generally be much more satisfied than those that receive conventional medical care. The aim of this study was to determine the short-term effectiveness of cervical spine manipulation as compared to Piroxicam administration in the treatment of chronic cervical facet syndrome. The study design that was chosen was that of a comparative clinical trial. Forty consecutive patients diagnosed with chronic facet syndrome of the cervical spine were randomly assigned to either the manipulation group or the NSAID group (twenty patients in each group). Each patient in group A received manipulative therapy of the cervical spine on three consecutive days. Each patient in group B received 40 mg of Adco Piroxicam on the first two days of treatment, and 20 mg daily for the remainder of the seven day treatment period. The patients were assessed by means of objective and subjective data obtained before each consultation on days 1, 3 and 7. The objective data was gathered from algometric pressure-pain threshold readings over the involved facet joint. The subjective information was obtained from the Short-Form McGill Pain Questionnaire, the Numerical Pain Rating Scale - 101 and the CMCC Neck Disability Index, as well as the patients perceived improvement which was recorded as a percentage on days 3 and 7.

Published: February 2022

BACKGROUND:

Pneumonia is among the most serious infections in the elderly. The evaluation of prognosis and predicting the outcome is essential in managing the treatment of patients with pneumonia.

OBJECTIVE:

Evaluate factors that might affect the mortality of elderly patients hospitalized for community-acquired pneumonia (CAP) in two age groups.

DESIGN:

Medical record review.

SETTINGS:

Tertiary care hospital.

PATIENTS AND METHODS:

The study included CAP patients who were hospitalized during the period from January 2017 and December 2019. The CURB-65 scale was chosen to assess the severity of pneumonia on admission. Multivariate analyses were conducted separately for patients younger than 75 years and 75 years or older.

MAIN OUTCOME MEASURES:

30-day mortality, factors associated with mortality.

SAMPLE SIZE AND CHARACTERISTICS:

1603 patients with a median age of 74, including 918 women (57%).

RESULTS:

The 30-day mortality rate was 6.5%. Patients with carbapenem-resistant gram-negative bacteria had lower survival rates (
P
<.0001). In the multivariate analysis, age, lung cancer, CURB-65, carbapenem resistance, and duration of hospital stay were associated with mortality in patients aged 75 years or older. Lung cancer, malignant disease, carbapenem resistance, duration of hospital stay and procalcitonin level were associated with mortality under the age of 75. Of 640 sputum cultures tested,
P aeruginosa
(42%) was the most common pathogen.

CONCLUSION:

The risk factors that affected mortality differed among patients aged 75 years or older versus younger patients. Our findings are important in determining factors associated with mortality in managing the treatment and follow up of hospitalized CAP patients younger or 75 years of age or older.

LIMITATIONS:

Single-center, retrospective.

CONFLICT OF INTEREST:

None.

How to critically read a meta-analysis of clinical trials in neurooncology
Authors: El Bairi Khalid
Published: February 2022

Evidence-based medicine (EBM) is an important field in oncology as it provides the tools needed to select the best available options for a better management of cancer patients and also for the whole decision-making process. Meta-analyses of randomized and controlled clinical trials are categorized in the high-level of evidence as they provide pooled results from several studies. This article type aims to comprehensively provide a synthesis of oncology literature in an unbiased,precise, and reproducible manner. However, a critical assessment of meta-analyses needs an advanced knowledge in biostatistics and critical reading methods. In this workshop, a methodic step-by-step examination will provide the needed information for oncologists and cancer researchers to critically appraise a meta-analysis of randomized and controlled trials with a particular focus on a clinical problem in neuro-oncology practice.Keywords : meta, -analysisn oncology literature, critical assessment, neuro-oncology practice
Team science: the power of Us
Authors: Abouelfetouh Alaa
Published: February 2022

In a world described as a global village where borders matter very little, many researchers seek scientific collaboration for different reasons, such as securing more funding, expertise and/or specialized equipment, new ideas, etc. Scientific collaboration (also known as team science) has many forms and can occur between researchers not necessarily at the same stage in their career. Collaboration can be internal within the same establishment or external, national or international,interdisciplinary or uni-disciplinary, of equal or different shares, each with its own sets of advantages and threats. However, when managed properly, team science increases opportunities and maximizes research impact. Yet, it comes with some challenges, including culture and language barriers, availability of funds to implement the collaboration, researchers’ grasp of the collaboration dynamics, etc. Finding the right collaborators with mutual or complementing interests is key for the success of the collaboration. So are good communication skills, trust and a clear understanding by all parties of the terms of the collaboration to minimize conflict. A successful collaboration is synergistic while being respectful of and building on each member’s potential. It is also a dynamic relationship with positive results that can reach far into the future beyond the actual duration of the collaboration.Keywords: scientific collaboration, Research impact, cultural and language barriers, Funding,Communication, Standards.
Design of Clinical Trials and Ethical Concerns in Neurosciences
Authors: Mehanna Mohammed M.
Published: February 2022

Neuroscience is an interdisciplinary science that works closely with other disciplines, such as mathematics, engineering, computer science, chemistry, philosophy, psychology, and medicine. The progress towards identifying novel and effective treatments for psychiatric diseases may be constrained by reliance on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Moving beyond the DSM will therefore be challenging, and regulators are open to alternatives, but lack efficient mechanisms to do so. The framework for ethical clinical trials takes into consideration the value, the scientific validity, favorable risk-benefit ratio, independent review, informed consent and the fair selection of subjects. With this knowledge comes the responsibility to prevent its misuse and abuse. The potential of new neuroscience knowledge is almost beyond comprehension. With this knowledge comes the responsibility to prevent its misuse and abuse. This effort begins with continued, interactive cooperation with others across disciplines to articulate and examine assumptions that underlie the professional and cultural values inherent in neuroscience. Understanding the historical foundations of ethics in neuroscience, its connectionsto other areas of modern science and bioethics, and the vital role that neuroethics must have, are key to illuminating its future.Keywords: Ethics, Neuroethics, Clinical trials, Neurosciences.
The possible analgesic effect of graphene oxide (GO)
Authors: RHAZOUANI Asmaa , GAMRANI Halima , AZIZ Faissal
Published: February 2022

Graphene oxide (GO), which is an oxidised derivative of graphene, is considered to be one of the recently emerging and attractive nanomaterials for biomedical applications. It has very interesting properties, such as nanometric size, specific surface area and electrical charge. The prospects for applications are accompanied by major concerns about its biosafety for human health. However, several studies show that nanomaterials used in biomedicine have an impact on health, which has not yet been well studied for GO. Thus, the objective of this study is to evaluate the effects of GO on the nervous system in male mice. After synthesizing these nanoparticles, size analysis was performed using a Mastersizer 3000 laser diffraction apparatus. The behavioural effects of this nanomaterial were studied after intraperitoneal injection of GO to mice at different doses (2 mg/kg and 5 mg/kg) for 5 days, using the hot plate test. The results of the particle size analysis showed that our nanomaterial has a uniform distribution, with an average grain size of about 50 nm, which means that our sample has a nanometric size. On the other hand, the results of the hot plate test showed that there is an analgesic effect. In summary, these results show that GO induced neural effects in mice, but the mechanism by which this occurs requires further study.Keywords: Analgesic effect, graphene oxide, male mice, nervous system, nanometric size.
Pituitary deficiency after brain radiation therapy in childhood
Authors: Rbiai Najoua , Latrech Hanane
Published: February 2022

Introduction: As part of an anticancer therapy, craniospinal radiotherapy causes variable degrees of hormonal deficiencies. The onset of hormonal deficiencies depends on the dose delivered to the pituitary –hypothalamic region while their incidence and severity depends on dose fractionating and follow up duration.

Objectives: Analyzing the long –term endocrine complications in children treated with craniospinal radiotherapy.

Material and methods: A prospective study; including 4 medical files collected over a period of 2 years.

Results: The study includes 4 patients with a sex ratio of 3M/1F; and a mean age of 18, 62 years. The average age at the time of irradiation was 9, 12 years. The delay between the end of radiotherapy and the first consultation varied between 1 year and 21 years. The radiotherapy was administred for medulloblastoma (n=1), Burkitt lymphoma (n=1), cavum cancer (n=1), Posterior Cranial Fossa Tumor (n=1).

The hormonal assessment revealed: a central hypothyroidism in 3 patients, corticotropin insufficiency in 2 cases, and gonadotropin deficiency associated with micropenis in one case. No cases of diabetes insipidus have been reported. Pituitary hypothalamic MRI objectified an atrophic anterior pituitary gland in two cases. Hormonal substitutive therapy was started in all patients. Recombined human GH treatment was introduced in one case, but omitted in two others cases for bad control of the cancerous disease and for an achieved puberty in the fourth patient.

Conclusion: The search of the hormonal deficiencies is essential for any child treated by craniospinal radiotherapy in order to institute an early hormonal substitutive therapy.

The influence of covid 19 on screening and management of colorectal cancers, case study of the agadir oncology centre
Authors: Ouaamr Ahmed , Fechtali Taoufiq
Published: February 2022

Colorectal cancer (CRC) is the 3rd cancer in the world after lung cancer and breast cancer, its incidence has increased over the past decade. It occupies the first place among digestive cancers in Morocco (40.3%), However, given the absence of a national cancer registry, there is no epidemiological data on all of Morocco. Based on data from the Greater Casablanca Cancer Registry (RCRC), the annual national cancer incidence is estimated at 101.7 new cases per 100,000 populations, which would equate to 30,500 new cancer cases each year.

In terms of frequency by sex, colorectal cancer is the second most common cancer in women and the third most common in men. It has significant human and financial consequences. Despite therapeutic and preventive advances, which have reduced mortality due to colorectal cancer, colorectal cancer still kills people around the world.

However, the advent of the Covid 19 pandemic has caused a delay in screening and a disruption in management, this article summarizes the main results of this delay and the risks on the evolution of colorectal cancers. The study is carried out at the Regional Oncology Centre of Agadir (CRO).

Published: February 2022

Epilepsy is among the most common neurological pathologies, affecting around 50 -70 million people from all populations worldwide. A high prevalence is estimated in underdeveloped and developing countries. Our aim is to assess the perception and knowledge of a sample of Moroccan population towards epilepsy. Epileptic and non-epileptic patients companying, were interviewed and a questionnaire on knowledge and attitudes about epilepsy was completed, in Neurological and Neurosurgical departments of Ibn Rochd University Hospital of Casablanca. Our results show that 5.7% of our group never heard of epilepsy. 26.3% have no idea about his neurological nature, while 52.5% attribute it to supernatural causes. 13,1% believe epilepsy is incurable, 13,1% doubt about its curability and 9,1% suppose it to be a disease of "insanity". Moreover, 5,1% consider that non-medical approaches (plants, marabouts and ''witchcraft'') as good first-line choices, while 31,6% who choose medicine first, intend to move towards these non-medical practices after a supposed ineffectiveness of the medical treatment. Therefore, our analysis reports that age (over 50), sex (women), area of residence (rural), source of information (general entourage) and the existence or not of an epileptic case in the family, are the main significant determining factors of the perception of our population on epilepsy. According to these preliminary results, we estimate that the consequences of such perception would lead to an inadequate management of an important part of patients, and certainly, more therapeutic difficulties and more complications. This highlights the interest of a good public awareness about this neurological disorder.

Huntington disease and the mechanisms of neuronal death
Authors: Berrada Sarah , Bouzroud Wafaa , Tazzite Amal , Dehbi Hind
Published: February 2022

Huntington disease (HD) is a neurodegenerative disorder caused by a CAG trinucleotide repeat expansions in the Huntington HTT gene inherited in an autosomal dominant manner. It is characterized by a motor, cognitive and psychiatric symptoms that progress to death within 10-20 years.  Herein we report two families with a dysfunction in the HTT gene causing a motor progression and cognitive deterioration. Indeed, both affected patients reported similar symptomatology characterized by involuntary movements (chorea), general motor impairment, depression and cognitive disorder. In order to detect the CAG-repeat in the HTT gene, a real time PCR analysis was performed. The diagnosis was confirmed because of the presence of a CAG trinucleotide repeat expansions in the HTT gene exceeding 35 repetitions. Thereby, the genetic counselling has been established and recommended for the other family members.

The HTT gene localized on 4p16.3 encodes for Huntington protein. CAG trinucleotide expansion in the HTT gene encodes for an abnormal polyglutamine tract in the huntingtin protein. The Huntington disease manifests when the number of the triplet is more than 35 repetitions causing an apoptosis in striatal neurons with a dysfunction in cytoplasm functions. The exact molecular mechanism by which the mutant huntingtin protein induces cell death as well as its function are not totally understood.  Genetic confirmation of the diagnosis is important for patient’s management and genetic counselling. Many therapeutic options are available for treating symptoms with a focus on life quality improve.

Distribution of coccoliths in surface sediments across the Drake Passage and calcification of Emiliania huxleyi morphotypes
Authors: Vollmar Nele Manon , Baumann Karl-Heinz , Saavedra-Pellitero Mariem , Hernández-Almeida Iván
Published: February 2022

Abstract. The Southern Ocean is experiencing rapid and profound changes in its physical and biogeochemical properties that may influence the distribution and composition of pelagic plankton communities. Coccolithophores are the most prolific carbonate-producing phytoplankton group, playing an important role in Southern Ocean biogeochemical cycles. However, knowledge is scarce about the record of (sub-)fossil coccolith assemblages in the Southern Ocean, which constitute invaluable indicators for palaeoenvironmental reconstructions.
This study investigates coccolith assemblages preserved in surface sediments of southernmost Chile and across the Drake Passage that were retrieved during R/V Polarstern expedition PS97. We focused on the coccolith response to steep environmental gradients across the frontal system of the Antarctic Circumpolar Current and to hydrodynamic and post-depositional processes occurring in this region. We used statistical analyses to explore which environmental parameters influenced the coccolith assemblages by means of cluster and redundancy analyses. We specifically assessed the morphological diversity of the dominant taxa, i.e. Emiliania huxleyi, emphasizing biogeographical variability of morphotypes, coccolith sizes and calcite carbonate mass estimations. High coccolith abundances and species diversity compared to studies in the same area and in other sectors of the Southern Ocean occur, with a high species richness especially south of the Polar Front. While the surface sediments offshore Chile and north of the Polar Front provide suitable material to reconstruct overlying surface ocean conditions, further factors such as temporary thriving coccolithophore communities in the surface waters or transport of settling coccoliths via surface and bottom currents and eddies influence the (sub-)fossil coccolith assemblages south of the Polar Front. Additionally, deeper samples in the southern part of the study area are particularly affected by selective carbonate dissolution. We identified five E. huxleyi morphotypes (A, A overcalcified, R, B/C and O) and estimated coccolith carbonate masses on the basis of scanning electron microscope images. E. huxleyi morphologies reflect diverging biogeographical distributions, trending towards smaller and lighter coccoliths to the south and emphasizing the importance of documenting those morphologies in relation to changing environmental conditions to assess their response to projected environmental change in the Southern Ocean.
The influence of lateral transport on sedimentary alkenone paleoproxy signals
Authors: Ausín Blanca , Haghipour Negar , Bruni Elena , Eglinton Timothy
Published: February 2022

Abstract. Alkenone signatures preserved in marine sedimentary records are
considered one of the most robust paleothermometers available and are often
used as a proxy for paleoproductivity. However, important gaps remain
regarding the provenance and fate of alkenones, as well as their impact on derived
environmental signals in marine sediments. Here, we analyze the abundance,
distribution and radiocarbon (14C) age of alkenones in bulk sediments
and corresponding grain-size fractions in surficial sediments from seven
continental margin settings in the Pacific and Atlantic oceans to evaluate
the impact of organo-mineral associations and hydrodynamic sorting on
sedimentary alkenone signals. We find that alkenones preferentially reside
within fine-grained mineral fractions of continental margin sediments, with
the preponderance of alkenones residing within the fine-silt fraction (2–10 µm) and most strongly influencing alkenone-14C age and sea
surface temperature (SST) signals from bulk sediments as a consequence of
their proportional abundance and higher degree of organic matter protection
relative to other fractions. Our results provide further evidence for the
key role of selective association of alkenones with mineral surfaces and
associated hydrodynamic mineral sorting processes on the reliability of
alkenone signals encoded in marine sediments (14C age, content and
distribution) and the fidelity of corresponding proxy records (productivity
and sea SST) in the spatial and temporal domain.
Atmospheric CO2 estimates for the Miocene to Pleistocene based on foraminiferal δ11B at Ocean Drilling Program Sites 806 and 807 in the Western Equatorial Pacific
Authors: Guillermic Maxence , Misra Sambuddha , Eagle Robert , Tripati Aradhna
Published: February 2022

Abstract. Constraints on the evolution of atmospheric CO2 levels throughout
Earth's history are foundational to our understanding of past variations in
climate. Despite considerable effort, records vary in their temporal and
spatial coverage and estimates of past CO2 levels do not always
converge, and therefore new records and proxies are valuable. Here we
reconstruct atmospheric CO2 values across major climate transitions
over the past 16 million years using the boron isotopic composition (δ11B) of planktic foraminifera from 89 samples obtained from two sites
in the West Pacific Warm Pool, Ocean Drilling Program (ODP) Sites 806 and
807, measured using high-precision multi-collector inductively coupled plasma
mass spectrometry. We compare our results to published data from ODP Site
872, also in the Western Equatorial Pacific, that goes back to 22 million
years ago. These sites are in a region that today is near equilibrium with
the atmosphere and are thought to have been in equilibrium with the
atmosphere for the interval studied. We show that δ11B data
from this region are consistent with other boron-based studies. The data
show evidence for elevated pCO2 during the Middle Miocene and Early to
Middle Pliocene, and reductions in pCO2 of ∼200 ppm
during the Middle Miocene Climate Transition, ∼250 ppm during
Pliocene Glacial Intensification and ∼50 ppm during the
Mid-Pleistocene Climate Transition. During the Mid-Pleistocene Transition
there is a minimum pCO2 at marine isotopic stage (MIS) 30. Our results are consistent with a
coupling between pCO2, temperature and ice sheet expansion from the
Miocene to the late Quaternary.
Climate change signal in the ocean circulation of the Tyrrhenian Sea
Authors: de la Vara Alba , Parras-Berrocal Iván M. , Izquierdo Alfredo , Sein Dmitry V. , Cabos William
Published: February 2022

Abstract. The Tyrrhenian Sea plays an important role in the winter deep
water formation in the northwestern Mediterranean through the water
that enters the Ligurian Sea via the Corsica Channel. Therefore, the study
of the impact of the changes on the future climate on the Tyrrhenian
circulation and its consequences represents an important issue.
Furthermore, the seasonally dependent Tyrrhenian circulation, which is rich in dynamical mesoscale
structures, is dominated by the interplay of local
climate and the basin-wide Mediterranean circulation via the water transport
across its major straits, and an adequate representation of its features
represents an important modeling challenge. In this work we examine with a
regionally coupled atmosphere–ocean model the changes in the Tyrrhenian
circulation by the end of the 21st century under the RCP8.5 emission
scenario, their driving mechanisms, and their possible impact on
winter convection in the NW Mediterranean. Our model successfully reproduces
the main features of the Mediterranean Sea and Tyrrhenian Basin present-day
circulation. We find that toward the end of the century the winter cyclonic
along-slope stream around the Tyrrhenian Basin becomes weaker. This
weakening increases the wind work transferred to the mesoscale structures,
which become more intense than at present in winter and summer. We also find
that, in the future, the northward water transport across the Corsica
Channel towards the Liguro-Provençal basin becomes smaller than today.
Also, water that flows through this channel presents a stronger
stratification because of a generalized warming with a freshening of upper
and a saltening of intermediate waters. Both factors may contribute to the
interruption of deep water formation in the Gulf of Lions by the end of the
century.

Abstract. The contribution deals with the comparison of two laser scanners manufactured by Leica company. In BIM modelling, there is a need for fast and accurate gathering of spatial data, e.g. point clouds. Those data can be gathered by photogrammetry or laser scanning. Last years on the market, there occurred some light and easy-to-use alternatives to classic laser scanners. There were chosen two scanners that belong to the easy-to-use category. The first scanner is stationary Leica BLK360 and the second scanner is Leica BLK2GO which is a handheld scanner based on SLAM technology. Both laser scanners were tested on three different test objects. The first object is an administrative building, the second object is a historical administrative building and the third object is the vaults of the church. In all cases, only the indoor side of the objects was measured. The point clouds were compared to each other and the comparison was discussed. The parameters derived from the point clouds were also compared to the parameters read in the original documentation of the object. The comparison of the parameters may show, how those point clouds are usable for the final BIM modelling.

PT. Ika Bina Agro Wisesa (IBAS) is a company that produces products in the form of crude oil or CPO (Crude Palm Oil). The company sets a minimum production target of FFB that must be processed to reach 30 tons in one boiling with a minimum production target of 600 tons/day. The company is required to increase productivity. The problem so far is that the company has never measured the productivity of the production process, which will then affect the achievement of production targets. Measurement of productivity is critical because the measursizeoductivity can determine whether the company meets productivity targets for production or not. Therefore, it is necessary to measure productivity to assess the value of productivity and efforts to increase productivity in CPO production and how to increase productivity in CPO production and efforts to increase productivity using the Objective Matrix (OMAX) method at PT. Ika Bina Agro Wisesa. Analysis of productivity using the OMAX method, ratio 3 (labor productivity) and ratio 4 (machine productivity) has a very high percentage of poor performance, which means that ratio and 4 have an insufficient level of productivity. Unlike the case with the achievement of productivity ratio 1 (productivity of raw materials) and ratio 2 (productivity of working hours) wh, ich shows a low percentage of poor performance, which means that the productivity level of ratio one and ratio 2 has a better productivity level than ratio three and ratio 4 Analysis The results of the productivity index in the company decreased and increased for each month, in November it experienced a decrease of -79.49, while in December it experienced a significant increase in the amount of 595.02 and January at 69.98. in February decreased to -23.63. Furthermore, productivity in March - September 2021 was unstable, with an increase and dropped for July, a decrease of -0.64 and, a slight increase in August of 0.28.
O posesivo non concordado en galego e en castelán de Galicia como mudanza sintáctica en curso
Authors: Silva-Domínguez Carme
Published: February 2022

O presente artigo ofrece unha análise de dous tipos de pronome posesivo non concordado que son posibles en galego e no castelán de Galicia. Por unha banda, o coñecido avance do paradigma cara a estruturas nucleadas por un adverbio de lugar, do tipo de diante miña. Pola outra, o menos descrito, mais tamén frecuente, posesivo carente de concordancia en locucións adverbiais de significado locativo e outras. Trátase de exemplos como ao lado súa e semellantes. A análise consiste nun baleirado dos corpus TILG, CORGA e CORILGA para o galego, ESLORA para o castelán de Galicia. Mediante eles dáse conta da cronoloxía do fenómeno e do poder explicativo dos seguintes factores no avance da innovación: a persoa gramatical, o tipo de adverbio ou locución adverbial, o grao de animación do antecedente, entre outros. Arguméntase, así mesmo, en favor da interpretación da mudanza como cambio desde abaixo, e descríbense os dous intentos de operar un cambio desde arriba sobre a innovación. Finalmente, achéganse evidencias en favor da interpretación do cambio sintáctico como endóxeno e procúrase unha explicación novidosa do fenómeno peculiar que representa a selección do xénero feminino para a forma de posesivo en ambos os sistemas lingüísticos.
Aquisição da escrita pelas crianças Apyãwa

Neste artigo, abordamos o processo de aquisição da escrita alfabética pelas crianças Apyãwa. Os povos indígenas são detentores de tradições orais, que garantem o acesso a saberes milenares. Muitos povos também apresentam um repertório extenso de motivos gráficos que, aplicados em pinturas corporais ou em artefatos diversos, refletem suas cosmologias e, assim, podem ser considerados como uma escrita ideográfica. Em pesquisas efetuadas com as crianças Apyãwa, chegamos a uma hipótese singular: a arte gráfica se entrelaça com as primeiras experiências de escrita, revelando que o lócus sociocultural marca o processo de aquisição de um objeto cultural originado em outras sociedades.
SISTEM PENGAMANAN MESIN ATM DENGAN MENGGUNAKAN PENGENALAN SIDIK JARI DAN WAJAH FACE RECOGNITION UNTUK MEMINIMALISIR CYBERBANKING CRIME
Authors: Arifin Mohamad
Published: February 2022

Mesin anjungan tunai mandiri (ATM) sangat mudahkan para nasabah perbankan dalam bertransaksi perbankan selama 24 jam tanpa terikat dengan jam operasional kantor bank. Nasabah cukup dengan menggunakan kartu dan memasukan nomor pin pada mesin, nasabah dapat bertransaksi non tunai dan penarikan uang. Tetapi, kelemahan mesin ATM yang menggunakan kartu sangat rawan peretasan. Biasanya, peretasan data nasabah menggunakan alat skimmer yang terpasang pada slot card mesin. Alat skimmer berfungsi  untuk mencuri data nasabah termasuk nomor rekening, jumlah saldo dan nomor PIN yang tersimpan pada pita electronic magnetic (berada di bagian belakang kartu). Data nasabah yang terekam dapat digunakan para hacker untuk menngandakan kartu nasabah dan mengambil uang nasabah dengan kartu atm duplikat. Tindakan haker tersebut sangat merugikan nasabah. Oleh sebab itu, diperlukan pengamanan mesin ATM yang bersifat biometric atau melekat pada diri manusia yaitu sidik jari dan wajah. Hal tersebut karena bentuk atau pola sidik jari manusia tidak sama antara satu individu dengan lainnya, begitu juga dengan wajah yang memiliki tingkat akurasi yang tinggi. Metode dalam penelitian terbagi dua yaitu pengumpulan data pendukung melalui studi literature tentang topik terkait dan selanjutnya perancangan grafis prototype mesin ATM dengan menggunakan pengenalan sidik jari dan wajah. Cara operasional yang dilakukan, nasabah melakukan perekaman sidik jari dan wajah ke kantor bank. Selanjutnya, petugas bank menvalidasi dengan data kependudukan yang memuat informasi biometrics nasabah. Jika sudah tervalidasi lalu petugas bank mensikronisasikan dengan rekening nasabah dan proses selesai. Nasabah dapat bertransaksi pada mesin ATM tanpa menggunakan kartu ATM. Cukup melakukan verifikasi sidik jari dan wajah pada mesin adapun output dari penelitian ini untuk meminimilisir tingkat kejahatan cyberbanking.
