A influência de autocitações em decisões editoriais e no Fator de Impacto: uma análise a partir da simulação de redes de citação
Authors: Correia Luiz Gabriel , Mena-Chalco Jesús Pascual
Published: August 2023

Introdução: A manipulação do Fator de Impacto de Periódicos (JIF) por meio de decisões editoriais que aumentam autocitações vem sendo verificada empiricamente em estudos recentes, levantando discussões a respeito de como evitar más práticas. Objetivo: Este trabalho tem como objetivo verificar se uma política de remoção das autocitações do cálculo do JIF é suficiente para remover os incentivos à manipulação. Metodologia: Introduzimos um modelo baseado em agentes da rede social acadêmica formada pelos periódicos para testar tal hipótese. Nós modelamos os periódicos como agentes racionais buscando ganhar posições no ranking JIF. Resultados: Os resultados das simulações mostram que a remoção de autocitações consegue reduzir significativamente a adoção de estratégias de manipulação (e.g., redução de 90% para 30%). Conclusão: Esse estudo contribui para compreensão do papel das autocitações no JIF e fornece ferramentas para o desenvolvimento de políticas que promovam a integridade da ciência.

Authors: Henao Castañeda Edison de Jesús , Romero Piedrahita Carlos Alberto , Ramírez Alzate Juan David
Published: August 2023

La aparición de diversos combustibles y sus estudios han aumentado significativamente a lo largo de los últimos años, principalmente buscando la reducción de emisiones y de consumo. Los combustibles tradicionales, sólidos y líquidos, han sido modificados y ahora se mezclan, en diferentes proporciones, con nuevos combustibles fósiles o derivados de bio-materiales, han reaparecido combustibles que habían sido apartados del uso constante en los motores de combustión interna como el etanol puro y se han adaptado tecnologías para la utilización de combustibles relativamente nuevos que tienen el potencial como alternativas al uso de los combustibles fósiles. El costo de investigaciones relacionadas con los combustibles es alto, principalmente por la poca adaptabilidad de los equipos de pruebas, los cuales pueden funcionar sólo en rangos muy limitados o requieren múltiples cambios en su estructura y componentes. La adaptabilidad de la relación de compresión (relación de compresión variable o RCV), sistemas de alimentación y encendido puede ayudar a la reducción de costos asociados a los múltiples equipos usados para cada tipo de combustible. La modificación de la relación de compresión y el tipo de combustión del motor son las principales características para modificar de tal modo que permitan el uso de combustibles pesados y ligeros, o, en otras palabras, de combustibles de encendido por compresión y por chispa, respectivamente. Para su diseño y construcción se realiza una revisión documental y clasificación de diferentes modelos utilizados en diferentes momentos históricos y se establece el estado del arte de los equipos con propiedades similares. Con los conocimientos obtenidos es esta etapa, se establecen los parámetros básicos que debe cumplir el diseño del motor. A partir de las diferentes soluciones potenciales, se realizan los diseños preliminares, estudios y simulaciones, se construyen prototipos y se evalúa la pertinencia de cada uno de ellos y su capacidad para realizar las diferentes pruebas para los combustibles.

Published: August 2023

A phosphine-catalyzed [4+3] annulation between dinucleophilic indole
derivatives and Morita−Baylis−Hillman (MBH) carbonates was discovered by
using the N1 and N4′ or C4′ nucleophilicities of indole precursors,
which provides an efficient and facile access to in-dole-1,2-fused
1,4-diazepinones and azepines in good to high yields in one step, in
which indoles act as four atom synthons. Various transformations of
products illustrate promising applications of the given protocols.

Published: August 2023

Background:Invasive mechanical ventilation is a crucial
intervention for the management of critical COVID-19 patients. However,
the impact of prone position (PP) on patients undergoing invasive
mechanical ventilation remains uncertain. This study aims to investigate
the potential benefits of PP in terms of improving the oxygenation index
and prognosis. Methods:A total of 289 critically ill COVID-19
patients were retrospectively gathered from ICU of three general
hospitals located in Taizhou, Zhejiang Province from December 1, 2022 to
February 1, 2023, all patients were invasive mechanical ventilated. 78
cases of PP group and 78 cases of non-PP group were matched with
propensity score matching. The study compared clinical data, laboratory
results, and hospitalization survival rate between two groups of
patients. Furthermore, we compared the laboratory results, and
hospitalization survival across varying numbers of PPs.
Results:The mean oxygenation index exhibited a greater increase
in PP group compared to non-PP group (48 vs 32mmHg). Hospital
survivors of PP group (63 patients) demonstrated more substantial
decrease in their Sequential Organ Failure Assessment scores and
C-reactive protein levels compared to non-PP group (51 patients). The
initial PP cycle resulted in a significant elevation of the oxygenation
index by 30.8 (-16.4,46.9) mmHg; the second PP cycle demonstrated a
maximum increase of 56.3 (13.0,92.8) mmHg. A higher frequency of PP
yielded a more pronounced improvement in oxygenation and had the
potential to enhance the survival rate. Additionally, the eight patients
who was improvements in their oxygenation index during the initial three
PP cycles and successfully survived had higher lymphocyte counts
(0.2-2.4) vs (0.1-0.5)×10 /L and a longer
duration of PP (53.0-113.5) vs (36.0-98.5)h.
Conclusion:PP has the potential to enhance the oxygenation
index and survival rates among critically ill COVID-19 patients invasive
mechanical ventilated. Notably, a positive correlation was observed
between the frequency of PP and the improvement of oxygenation. Our
investigation further revealed that the efficacy of the PP may be
influenced by lymphocyte count and duration of PP.
HIGH MOMENT AND PATHWISE ERROR ESTIMATES FOR FULLY DISCRETE MIXED FINITE ELEMENT APPROXIMATIONS OF THE STOCHASTIC STOKES EQUATIONS WITH MULTIPLICATIVE NOISE
Authors: VO LIET
Published: August 2023

This paper is concerned with high moment and pathwise error estimates
for both velocity and pressure approximations of the Euler-Maruyama
scheme for time discretization and its two fully discrete mixed finite
element discretizations. Optimal rates of convergence are established
for all pth moment errors for p≥2 using a novel bootstrap
technique. The almost optimal rates of convergence are then obtained
using Kolmogorov’s theorem based on the high moment error estimates.
Unlike for the velocity error estimate, the high moment and pathwise
error estimates for the pressure approximation are proved in a
time-averaged norm. In addition, the impact of noise types on the rates
of convergence for both velocity and pressure approximations is also
addressed. Finally, numerical experiments are also provided to validate
the proven theoretical results and to examine the dependence/growth of
the error constants on the moment order p.
The thermal breadth of temperate and tropic freshwater insects supports the Climate Variability Hypothesis
Authors: Dewenter Beatrice , Shah Alisha , Hughes Jane , Poff LeRoy , Thompson Ross , Kefford Ben
Published: August 2023

Climate change involves increases in mean temperature and changes in
temperature variability at multiple temporal scales. Research on species
response to climate change has focussed on changes in mean temperature.
Thus, there is a need to consider how species will respond to changes in
temperature variability. The Climate Variability Hypothesis (CVH)
provides a conceptual framework for exploring potential effects of
annual scale thermal variability across climatic zones. The CVH predicts
ectotherms in temperate regions tolerate a wider range of temperatures
than those in tropical regions in response to greater annual variability
in temperate regions. However, various other aspects of thermal regimes
(e.g. diel variability), organisms’ size and taxonomic identity may also
influence thermal tolerance. Indeed, high temperatures in the tropics
have been proposed as constraining organisms’ ability to tolerate a wide
range of temperatures, implying that high annual maximum temperatures
would be associated with tolerating a narrow range of temperatures. We
measured thermal regimes and critical thermal limits (CTmax and CTmin)
of insects in the orders Ephemeroptera (mayflies), Plecoptera
(stoneflies) and Trichoptera (caddisflies) along elevation gradients in
streams in temperate and tropical regions of eastern Australia and
tested the CVH by determining which variables were most correlated with
thermal breadth (Tbr = CTmax - CTmin). Consistent with the CVH, Tbr
tended to increase with increasing annual temperature range and
increasing body size. Tbr was generally wider in Plecoptera than in
Ephemeroptera or Trichoptera. We found no evidence that higher annual
maximum temperature constrained individuals’ abilities to tolerate a
wide range of temperatures. The support for the CVH we document,
suggests that temperate organisms may be able to tolerate wider range of
temperatures than tropical organisms. There is an urgent need to
investigate other aspects of thermal regimes, such as diel temperature
cycling and minimum temperature.
Microalgae cultivation: closing the laboratory-field yield gap
Authors: Plouviez Maxence , Guieysse Benoit
Published: August 2023

Microalgal biotechnologies attract considerable research investment on a
premise that microalgae cultivation is highly productive and
sustainable. Unfortunately, and despite decades of commercial experience
and research investment, only a few commercial microalgae cultivation
and processing facilities are currently in operation. Microalgae
cultivation indeed remains costly and complex to implement, and the
large scale required to achieve commercial viability in low-value
applications has critical implications on productivity and local
environmental impacts. However, microalgae biotechnology is still a
developing field, and we believe technological advances in strain
selection (and rotation) as well as process design, operation and
control will double current commercial productivities from 6 (current)
to 12 (future) g-DW·m ·d . These
gains, together with process integration withing existing supply chains,
should greatly improve the adoption of microalgae cultivation,
especially in the agri-food sector. To achieve this, future investment
must also address the numerous non-technical constraints associated with
microalgal production at scale.

Published: August 2023

We designed and constructed a green, sustainable, and nongenetically
modified organism (non-GMO) bioprocess to efficiently coproduce
-tagatose, bioethanol, and microbial protein from whey
powder. First, a one-pot biosynthesis process involving lactose
hydrolysis and -galactose redox reactions for
-tagatose production was established in vitro via a
three-enzyme cascade. Second, a nicotinamide adenine dinucleotide
phosphate-dependent galactitol dehydrogenase mutant, D36A/I37R, based on
the nicotinamide adenine dinucleotide-dependent polyol dehydrogenase
from Paracoccus denitrificans was created through rational design and
screening. Moreover, an NADPH recycling module was created in the
oxidoreductive pathway, and the tagatose yield increased by 3.35-fold
compared with that achieved through the pathway without the cofactor
cycle. The reaction process was accelerated using an enzyme assembly
with a glycine–serine linker, and the tagatose production rate was
9.28-fold higher than the initial yield. Finally, Saccharomyces
cerevisiae was introduced into the reaction solution, and 266.5 g of
-tagatose, 371.3 g of bioethanol, and 215.4 g of dry
yeast (including 38% protein) were obtained from 1 kg of whey powder
(including 810 g lactose). This study provides a promising non-GMO
process for functional food (-tagatose) production.
Moreover, this process fully utilized whey powder, demonstrating good
atom economy.
Determination of Mechanical Properties of Fruit Shell Powders Reinforced Wood Plastic Composite (WPC) Materials and Case Study for I-Type Snap-Fit Model
Authors: ERDEMİR Fulya , ÖZKAN Murat Tolga
Published: August 2023

High quality material production has been among the work of many researchers in recent years. These materials, which are obtained mostly by the production of composite materials, enable the production of lighter, more durable and less costly products. Increasing environmental pollution in recent years, protection of natural resources and ensuring recycling have increased the importance of wood plastic composite material production. In this study, wood plastic composite material was obtained by using ABS (Acrylonitrile butadiene styrene) plastic material and six different fruit shell powders (walnut, pistachio, peanut, almond, hazelnut and apricot shell). The mechanical properties of the obtained composite material were determined and its effect on the I type snap-fits was analyzed in ANSYS software. When the resulting composite material's mechanical properties were tested, it was found that the density and tensile strength decreased while the Vicat softening point value and melt flow rate increased. In the analysis performed using the ANSYS software, it was found that the composite I type snap-fit design of the same size can resist 12.6% N less force when the material is subjected to its maximum values when it achieves the elongation at break value.
Unterwuchsbewirtschaftung im Apfelanbau und potenzielle Nahrungsquellen im Unterwuchs für Honigbienenvölker
Authors: Geier Jacob , Mair Benjamin , Wolf Manfred
Published: August 2023

Der Apfelanbau ist mittlerweile nicht mehr aus Südtirol wegzudenken. Auf rund 18.300 ha werden ca. 10 % der Äpfel auf dem europäischen Markt produziert. Da die Apfelanlagen in manchen Teilen der Region über 75 % der landwirtschaftlich genutzten Fläche einnehmen, haben sie auch einen Einfluss auf die dort vorkommende Fauna. So kann z.B. der blühende Unterwuchs von Insekten als Nahrungsquelle für Pollen und Nektar verwendet werden. Diese Studie beschäftigt sich mit dem Unterwuchsmanagement und dessen Auswirkungen auf die Vegetation in den Apfelanlagen. Es wird gezeigt, dass das Mulchen des Fahrstreifens, sowie Herbizidbehandlungen in den Baumreihen sehr wohl Auswirkungen auf die Unterwuchsvegetation haben, diese aber nur relativ kurzfristig sind und deshalb im richtigen Moment erfolgen müssen. Es ist zwar kaum möglich alle Blüten aus dem Unterwuchs zu entfernen. Totzdem kann durch das richtige Management der Vegetation der Anreiz für Bestäuber in die Anlagen zu fliegen, und somit das Risiko, dass sie mit Pflanzenschutzmitteln in Kontakt kommen, minimiert werden.
Robotic Simple Prostatectomy for Giant Prostate
Authors: Albadawe Hani Saleh
Published: August 2023

Benign prostatic hyperplasia (BPH) is a pathological process that contributes to, but is not the sole cause of lower urinary tract symptoms (LUTS) instead age-related detrusor changes and other common medical conditions are the causative factor in many cases. Despite this, benign prostatic hyperplasia (BPH) is still a significant cause of LUTS. The options for management are variable and include watchful waiting, medical therapy, and surgical intervention. Simple robotic prostatectomy was used as the treatment procedure of choice for the patient in this report since he has a large prostate, and according to the AUA and EAU guidelines, surgical management with prostatectomy is the gold standard for such cases. The benefits of using such a technique include precise removal of the prostate gland, minimal blood loss, a smaller opening, less pain, short stay in the hospital, and a reduced requirement for blood transfusion. In the end, it was one of the preferred methods to be utilized for prostate surgery.

Authors: Xu Bin
Published: August 2023

Objective: To observe the effect of platelet-rich plasma (PRP) on reducing ear cartilage absorption and nasal tip complications after nasal tip plasty with medpor prosthesis. Methods: During the conventional medpor rhinoplasty, PRP was injected locally around the tip and columella of the nose with medpor material. The morphology of the nasal tip cartilage and the shape of the nasal tip were observed at least 1 year after the surgery, and the status of cartilage absorption was judged. The statistical differences between the control group and the experimental group were analyzed by χ²-test. Results: After observation for 1 year, a total of 71 cases underwent conventional medpor rhinoplasty, of which 21 cases had cartilage resorption, and 10 cases had a prominent shape of the nasal tip prosthesis that required repair; In the platelet-rich plasma treatment group, there were 18 cases, 1 case of cartilage absorption, and 0 case requiring repair. There are significant statistical differences in clinical practice. Conclusion: PRP can significantly reduce the absorption of ear cartilage, maintain the appearance of the nasal tip, and improve the satisfaction of patients with medpor prosthesis rhinoplasty

Description of Neoechinorhynchus pikensis n. sp. (Acanthocephala: Neoechinorhynchidae) from Catostomus commersoni (Lacépède) in Wisconsin, USA
Authors: Amin Omar M
Published: August 2023

Neoechinorhynchus pikensis n. sp. is described from one whole-mounted male specimen that was collected a few decades ago but went missing. It was collected from an individual white sucker, Catostomus commersoni (Lacépède) captured in the Pike River, Kenosha County and has never been found subsequently despite the examination of many collections of white suckers since. It is distinguished from other species of Neoechinorhynchus Stiles and Hassall, 1905 by a combination of the following diagnostic characters: Trunk small, straight anteriorly but slightly curled ventrad posteriorly; body wall with similar thickness dorso-ventrally; cuticle of proboscis and neck conjoined as one sheet of thick, dark chitin-like layer; proboscis wider than long with long anterior hooks with short round roots; hooks in second and third circles much smaller and rootless; receptacle three times as long as proboscis with a triangular cephalic ganglion at its base; lemnisci relatively long and equal, not reaching anterior testis; all male reproductive structures contiguous in posterior two thirds of trunk; testes pre-equatorial; anterior testis larger than posterior testis; large syncytial cement gland with 10 giant nuclei; cement reservoir prominent branching in 2 long cement ducts surrounding Saefftigen’s pouch. Comparisons with worldwide and North American related species that have partially similar features are made. It is proposed that the holotype may be part of a larger population in southwest Lake Michigan where the Pike River flows and where a continuous population of C. commersoni survives.

Current Frontiers in Ureteral Stent Development
Authors: ShI Giyasov
Published: August 2023

This article describes the early history of stents, their current state, and future directions. We analyzed the PubMed, EMBASE, Web of Science, and Cochrane Library databases up to December 2021 to find recent information about future stent developments. Today, ureteral stents are widely used in urology for the treatment of upper urinary tract obstruction. However, the polymeric materials from which stents are made are prone to bacterial colonization, the development of urinary tract infections and salt encrustation. In addition, stents, after performing their function, require additional interventions to remove them. The new generation of stents will have improved properties, antibacterial activity, and biodegradability in the body
Recent Advances in Biowaste-Derived Bifunctional Catalysts in Biodiesel Production: A Mini-Review
Authors: B Changmai
Published: August 2023

There is a growing need for alternative energy sources due to rising concerns about global warming, the depletion of fossil fuels, and the consequences of particulates generated during their usage. In this regard, biodiesel serves as a renewable and comparatively clean alternative to fossil fuels because it is non-toxic, environmentally friendly, sustainable, biodegradable, and made from renewable sources like animal fats or edible/inedible oils. Additionally, it requires minimal modification to be used with the current fuel infrastructure when blended with petrodiesel. Animal fat or oil is (trans)esterified with a catalyst to produce biodiesel. Due to their improved adherence to the 12 Principles of Green Chemistry, solid catalysts are currently surpassing homogeneous catalysts. Besides, bifunctional solid catalysts are more highly desired than their monofunctionalized analogues because they can enhance product selectivity and make it easier for coordinated, one-pot processes to convert nonedible oils to biodiesel. The objective of this mini- review is to evaluate the developments in bio-waste-derived bifunctional catalysts for the synthesis of biodiesel from non-edible oils between 2019 to the present.

Published: August 2023

Objective: determine the extent to which each criterion of the frailty phenotype (either alone or grouped) contributes to the emergence of the syndrome in older people. Methods: observational and analytical study was conducted with 219 male and female older people in outpatient care. The evaluation of frailty syndrome was based on the phenotype proposed by Fried et al., the criteria of which are unintentional weight loss, self-reported fatigue, low grip strength, insufficient physical activity and slow gait. Multinomial logistic regression analysis was employed to evaluate the influence of each criterion of the phenotype alone or grouped. Results: a total of 219 individuals participated in the study. The most common frailty criterion was slowness in both frail and pre-frail individuals. Pre-frail individuals with slow gait were 9.42-fold more likely to become frail (OR = 9.42, 95%CI: 7.27-13.40, p = 0.001). The model with all five criteria explained 99.5% of frailty in the sample. Conclusion: slow gait was the most frequent frailty criterion in frail and pre-frail individuals. Therefore, this criterion seems to be the best predictor of frailty in older people and warrants close observation on the part of healthcare providers.

Authors: Dewi Pramita Sylvia , Widodo Ari , Rochintaniawati Diana , Prima Eka Cahya
Published: August 2023

This study aims to identify science learning activities for junior high school students. The research design is descriptive and quantitative. The sample in this study was 38 students, and the questions tested consisted of 28 items analyzed by Rasch analysis. Question items are correct if students can answer questions according to their guided inquiry abilities. The results showed that almost all samples could not participate in science learning using guided inquiry. Of the 28 questions tested on students, only three had a score above 50%, and the rest were almost, on average, below 50%. It can be concluded that students have yet to realize that guided inquiry is the essence of science learning, which helps them conduct and develop science learning in the classroom. This study recommends the application of guided inquiry to students to be able to harmonize thinking in science learning in junior high school.

Eucalypts of Hodogaya: Organic cultural diplomacy at Yokohama War Cemetery
Authors: Tsakonas Athanasios , Pieris Anoma
Published: August 2023

Located within a former Hodogaya recreation park about 5 kilometres west of the city centre, the 27-acre Yokohama War Cemetery is the primary commemoration and remembrance site for Commonwealth Allies of the Second World War within mainland Japan. Alongside Hiroshima Peace Park and Tokyo’s Yasakuni Shrine, it serves to remind both foreign nationals and locals of war’s consequences. Yet beyond official narratives, its establishment in the peripheral city of Yokohama, rather than Tokyo, Japan’s imperial, cultural, and political heart remains relatively unknown. This paper aims to understand better Australia’s significant role in this war cemetery’s creation. Under the auspices of the Australian War Graves Service, Australian and Japanese designers and the contractors of both nations collaborated to create a significant setting for deceased servicemen and women. Whilst ostensibly another of the Commonwealth War Graves Commission’s many such sites worldwide, Australian involvement offers an alternative interpretation of its conception. By examining the factors leading to the considered allocation of the site and its subsequent layout design, this study intends to enhance our knowledge of this important Australian contribution to our region—by asking why this war cemetery differs considerably from the orthodox nature of the conventional war cemeteries; by unveiling the many unknown architects, landscapers, contractors, and officials that put aside differences to collaborate on this war cemetery and its memorials; and by recording and analysing the careful detailing and construction of the memorials using local and imported materials. The lens from architectural history offers unique insights into these processes.

Authors: Kumala Ida Ayu Ratna , Sudantra I Ketut
Published: August 2023

It is generally said that disabled persons do not have proper access to justice and are not treated equally before the law. In Indonesia, the human rights approach has been incorporated into developing laws and policies for disabled persons. However, disabled people still face legal difficulties. This article aims to discuss the legal capacity of a deaf person to perform the legal action of making a deed before a notary in Indonesia from the perspectives of human rights, contracts, and notary laws. It reflects legal research that uses a statutory and conceptual approach. Primary legal materials are obtained from the national laws and regulations of Indonesia and relevant international legal instruments, while secondary legal materials are obtained from books, journal articles, and website content. The findings reveal that Indonesian national law generally recognizes the right of persons with disabilities, including deaf people, to perform civil law actions. In general, deaf people can sign a contract; however, there is no guarantee that they understand the communication process in making a deed. In this context, there are still obstacles related to the lack of sign language interpreters in Indonesia, which can complicate the transferring of information when making notarial deeds between deaf clients, notaries, and witnesses.

Measuring Corruption Tendency in Exercising Authority of the Proxy of Budget User: A Legal Culture Perspective
Authors: Sudarsana I Made , Rahayu Gorda AAA Ngurah Sri
Published: August 2023

Presidential Regulation No. 12 of 2021 on the Amendment to Presidential Regulation No. 16 of 2018 on Government Procurement (PR 12/2021) expands the authority for the Proxy of Budget User (PBU) to become Commitment Making Officer. Consequently, the process of procuring government goods/services is controlled by a single person; such a condition can facilitate various forms of criminal acts, especially corruption. This study aims to analyze the dual position of PBU as a Commitment Making Officer, the tendency of corruption due to the expansion of PBU’s authority, and the reformulation of PBU’s authority in the future. It is normative juridical research that examines PR 12/2021 with a qualitative analysis approach. Amendment to the Presidential Regulation on Government Procurement includes the legitimacy of PBU as a Commitment Making Officer without any requirements as stated in the previous regulation. Among others, this study underlines that centralized authority will have implications for a more robust culture of corruption due to the absence of control from other parties. In future provisions, PBU may not hold a concurrent position as Commitment Making Officer in accordance with the principles of transparency and accountability. The culture of professionalism in the procurement of government goods/services needs to be improved to reduce the culture of corruption, collusion, and nepotism.

Textband
Authors: Gottfried von Straßburg
Published: August 2023

Eine wissenschaftlich abgesicherte Edition von Gottfrieds Tristan-Roman gehörte lange zu den größten Desideraten der germanistischen Mediävistik: Bisher gab es keine Ausgabe, die einen verlässlichen Text oder einen vollständigen Variantenapparat bot. Mit dieser Ausgabe wird erstmals eine transparente, textkritisch reflektierte und autornahe Edition vorgelegt, die die gesamte Überlieferung berücksichtigt. Sie stellt Variantenmaterial, textkritische Erklärungen, forschungsgeschichtliche Einblicke und zahlreiche Verständnishilfen zur Verfügung, wie sie für Gottfrieds Werk bislang noch nicht vorgelegen haben. Damit soll sie auch die zukünftige Forschung anregen.
حجية البصمة الصوتية الأدمية في الاثبات المدني

كل يوم يطل علينا العلم باكتشاف جديد وهو ما ينعكس على الواقع القانوني، من ذلك ما توصل اليه العالم ( لورانس كريستي) من ان للصوت بصمة تميز كل شخص عن غيره، رغم اشتراك بنو البشر بنفس التركيب والبنية ووحدة الاعضاء والوظائف الفيزيائية للجسم، إلا ان مشيئة الله قضت بان ينفرد كل انسان ببصمة صوت تميزه عن غيره. وتمكن الباحثون من تحديد هوية المتصل من خلال بصمة صوته، وهو ما اسهمت به التكنلوجيا الحديثة من خلال جهاز يعرف بـ (spectrographs)، او بواسطة الالة والتي ساعدت في تحديد بصمة صوت الشخص ومن ثم تحديد شخصيته. وترى الشركات المتخصصة في القياسات الحيوية للصوت ان بوسعها تحديد هوية الاشخاص بدقة تصل الى (99%). وفي ظل التطور الهائل والمستمر في وسائل التواصل والتي تتضمن اغلبها امكان التواصل الصوتي وهو ما اتاح ابرام شتى انواع التصرفات القانونية من خلالها من جهة، لاسيما تلك التي يوجب المشرع اجرائها باللفظ كإبرام عقد الزواج، او القيام بأفعال يمكن ان تكّون خطئا تنشأ عنه المسؤولية التقصيرية. وهو ما يدعو الى تحديد هوية صاحب الصوت لتحديد أطراف التصرف القانوني ومن ثم تحديد المتحمل بالالتزام او صاحب الحق من جهة، او تحديد مرتكب الفعل الضار الذي تم بوسيلة من وسائل التواصل الصوتي من جهة اخرى.
