Authors: Bukar Zara Ibrahim , Arabaci Ahmet 
Published: January 2024

Nigeria-China relations had a considerable influence on Nigeria's development, and the Peoples Republic of China emerged as one of Nigeria's primary commercial partners and a major source of foreign direct investment (FDI) in recent decades. To this, the relationship between the two nations has influenced Nigeria's growth in various ways, especially in the area of infrastructure development obtained through loans, investments, skills and technology transfer. China has contributed to the development of Nigeria’s infrastructure, thus, fostering economic growth in addition to influencing regional integration. Furthermore, in the energy and power sectors, Chinese firms have been involved in the construction of power plants, transmission lines, and renewable energy projects in Nigeria aimed at addressing power deficits and improving access to electricity, which is essential for industrial development and improving Nigerians' quality of life. China is one of Nigeria's top commercial partners and a substantial source of foreign direct investment (FDI). Chinese enterprises working in Nigeria have provided technology, skills, and knowledge transfer that has benefited Nigerian industries. Chinese investments in industries like telecommunications, manufacturing and agriculture have eased the transfer of technical skills while also increasing efficiency in production methods. This paper aims to illustrate the importance of bilateral trade relations as a means of change and development especially when the nations involved are in need of each other. The paper adopts qualitative approach to the study of international relations. The paper adopts dependency theory to analyze bilateral trade relation between Nigeria and China. The theory believes that trade should only be done to enhance prosperity and also argued that the principle of comparative advantage ensures everyone would profit from the interaction. The paper reveals and concludes that Nigeria-China relations have made a substantial impact on Nigeria's economic development notwithstanding some notable deficiencies that have arisen in areas of unfair labour practices amongst others

Published: January 2024

The Batang III Industrial Workers Flats Construction Project is part of the construction of the Batang integrated industrial estate, where these flats will be a residence for workers in the Batang industrial area later. In the initial design of this project used the full precast upper structure method. This method requires a fairly high implementation cost, so changes were made to the precast / precast VE implementation method. The purpose of the study was to determine the cost efficiency between the upper structure method of full precast, VE precast column multi floor, conventional and choose the type of method that is more economical as an alternative option. This type of qualitative research uses the Value engineering (VE) method, the VE method is one of the well-known methods and has a considerable potential for success in controlling costs. This technique uses an approach by analyzing its function. The process carried out is to reduce cost reduction as far as possible while still paying attention to the desired quality and reliability. The results of this study showed that in the upper structural work of the Batang III industrial worker apartment project, it was found that the initial cost of the full precast method at a cost of Rp. 6,418,779,618,-, the conventional method amounted to Rp. 7,414,918,929, - and the VE precast method multi-floor column joint CCP, precast beam, combination of precast plate and conventional plate in the wet area amounted to Rp. 5,650,987,713, - with a cost difference of Rp. 767,791,904, - or 11.96%, it can be said that the VE precast method multi-floor joint CCP column, precast beam, combination of precast plate and conventional plate in wet areas is cheaper than the full precast method and full conventional method by considering quality results and implementation time

In 1994, a high speed towing system (the maximum speed of which is 15m/s) was developed to investigate the performance of high-speed planing craft at Osaka Prefecture University. Nowadays, the system has many experimental devices, and resistance and propulsion test, seakeeping test, maneuvering test and so on can be carried out.
In this paper, because dynamic instability is one of important performance of high speed planing craft, the experimental techniques using the above-mentioned devices and the analyzing procedures, that were developed to estimate the occurrence possibility of some dangerous motions, are explained. And some results are also shown.
The Effects of Deadrise and Deadrise Variation on Steady Planing Hull Performance
Authors: Savander Brant R. , Maki Kevin J. , Land Jan 
Published: January 2024

Historically, planing surfaces have been successfully used in a wide variety of practical applications ranging from flying boats of the 1930’s to the high-speed recreational, commercial, and military craft of the modern era. Planing hull analysis technology spans a similar time frame. The pioneering works of von Karman (1929) and Wagner (1932) were motivated by military interests in flying boats. Similarly, in the United States, Davidson Laboratories conducted and enormous amount of experimental research starting largely in the World War II time frame. One of the seminal publications related to planing hull performance prediction is Savitsky (1964), based upon research conducted at Davidson Laboratories. A major motivation for the Savitsky (1964) work, was to be able to provide the naval architect with a tool to assess steady planing performance in a meaningful way during the preliminary design process. Savitsky (1964) allowed the designer to study tradeoffs between variables such as deadrise angle, , chine beam, , planing surface length, longitudinal center of gravity, vessel weight, and shaft angle.
As the 2010 Chesapeake Bay Powerboat Symposium is honoring the professional accomplishments of Dr. Daniel Savitsky, the work contained herein is motivated by the example set by Dr. Savitsky in successfully applying fundamental research findings to practical planing hull naval architecture problems.
In the spirit of Savitsky (1964), the work of Savander (1997) and Savander, et al., (2002) was motivated by the need to provide the planing hull designer with a tool to assess steady planing performance that allowed for sufficient geometric sensitivity in a computationally efficient manner. These methods are based upon application of a slender body theory approach in conjunction with an ideal flow theory formulation. Savander, et al. (2002) revealed explicit definition of general deadrise variation, B (x,z), in the formulation for dynamic lift and drag, where the horizontal plane is defined by (x,z).
The formulation presented in Savander, et al. (2002) is implemented in a numerical program identified as SEAdyn. SEAdyn is used herein to analyze the calm water resistance characteristics of a series of geometrically related planing surfaces created by systematic variation of deadrise, B (x,z), as may be used by the naval architect in the planing hull design process. The baseline hull configuration corresponds to the 70-ft planing hull (JB70) presented in Savander, et al. (2008) which was extensively tested at model scale by MARIN, and at full scale by MTU - Detroit Diesel. The performance of the hullform variants is presented and compared to model test results obtained by MARIN for the JB70. The hullform that which displayed the most favorable resistance improvement is be analyzed, as part of an ongoing effort, with the RANS solvers STAR-CCM+ and OPENFOAM. The results from model tests, SEAdyn, STAR-CCM+, and OPENFOAM are all be presented and the merits of each analysis approach discussed.

La Universidad Autónoma Agraria Antonio Narro (UAAAN) y en la Angostura, Saltillo, Coahuila, México, y plantea la rehabilitación ecológica a través de la aplicación de materiales orgánicos sobre el suelo e incorporado a él, de acuerdo a dos factores: prácticas de manejo y material orgánico, analizados en parcelas divididas en espacio y tiempo. Se seleccionaron los mejores tratamientos con prueba de medias en parcelas apareadas. Las variables de respuesta fueron: cobertura, propiedades fisicoquímicas del suelo, peso verde y seco de gramíneas, así como simulación de lluvia. El trabajo fue definido como análisis inicial 1994 y final 1995, lo cual permitió conocer cómo el material orgánico sobre e incorporado se expresaron en un crecimiento vertical y horizontal de gramíneas y herbáceas, que sustituyen al suelo desnudo, piedras y musgos y mejoran las propiedades físico químicas del suelo. Al simular lluvia, se determinó la concentración de sedimentos donde derivan el material mineral, el orgánico (g/lt) y la infiltrabilidad, y se detectó que existen diferencias considerables entre el testigo con respecto al resto que se le aplicó material orgánico, pero entre éstos la diferencia fue menor, lo que significa que todo movimiento sobre e incorporado al suelo en su momento, es magnífico. Cada tratamiento se apoyó en el inicio del escurrimiento, que se refiere al tiempo en minutos que tarda el agua en correr dentro de la parcela hacia el tubo de succión, y en los testigos el escurrimiento inició en pocos segundos.

Is Subclassification by Number of Fracture Fragments Necessary for Sanders Type IV Calcaneal Fractures?
Authors: Kim Dong-Hee , Kim Jhee-Yun , Lee Kwang-Bok 
Published: January 2024

Background: The Sanders classification is a widely used method for classifying calcaneal fractures. Type IV fractures (>4 fragments) are known to vary in the number of fracture fragments. However, all relevant cases are classified as type IV irrespective of the number of fragments. We investigated the need for evaluation of postoperative prognoses based on radiologic factors and subtypes of Sanders classification type IV fractures.
Methods: Fifty-six Sanders type IV calcaneal fractures were enrolled between 2010 and 2018. Patients were divided into two groups according to the number of fragments: four fragments (group 1) and more than four fragments (group 2). Radiologic evaluation was performed using a postoperative recovery percentage calculated from postoperative reduction of the Böhler angle, Gissane angle, and vertical height. Radiologic evaluation was divided into two groups according to postoperative recovery: good and bad recovery groups. American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analog scale (VAS) score were used for clinical outcome evaluation.
Results: There was no significant difference in AOFAS ankle-hindfoot score (P = .909) or VAS score (P = .963) between groups 1 and 2. However, there was a significant (P = .001) difference in AOFAS ankle-hindfoot score or VAS score between good and bad recovery groups.
Conclusions: Clinical results of Sanders type IV fractures were not related to the number of bone fragments but to the degree of injury to the Böhler angle, Gissane angle, and vertical height. Therefore, subtype classification of type IV calcaneal fractures is superfluous, and it is important to try to restore these parameters during surgery.

Published: January 2024

Background: Kaposi sarcoma (KS) has multiple clinical variants, and most frequently presents on the lower extremities. Anti–human immunodeficiency virus (HIV) therapy has significantly reduced the incidence of KS. However, KS is still prevalent in both HIV-infected and HIV-uninfected patients. This case series analysis aims to reveal the clinical presentations, differential diagnosis, and treatment options of KS on the foot and ankle.
Methods: Eleven cases of KS involving the foot and ankle were retrieved from our patient database, and their clinicopathologic features were analyzed.
Results: All patients were men, aged 29 to 85 years. Two types of KS were found: classic and acquired immunodeficiency syndrome–associated epidemic. The average ages of classic and epidemic KS were 65.7 and 41.8 years, respectively. Clinically, three patients manifested multiple erythematous or deep violaceous, or blue-violaceous macules on either the dorsal or plantar surfaces of both feet. Eight patients showed exophytic, pyogenic granuloma-like nodules on the plantar surface, heels, and toes. Histologically, all KSs had uniform intervening fascicles of elongated spindle cells with slit-like vascular spaces filled with red blood cells and immunoreactivity with human herpesvirus-8. The patients were treated according to HIV infection status. Human immunodeficiency virus–infected patients were treated with anti-HIV therapy after primary surgical excision or biopsy. Human immunodeficiency virus–negative patients were treated with either surgical excision, Mohs surgery, or a combination of surgical excision and local radiotherapy according to individual patient clinical presentation.
Conclusions: Kaposi sarcoma is still prevalent in both HIV-infected and HIV-uninfected patients with a variety of clinical presentations. Biopsy, with histologic evaluation, in combination with immunohistochemistry is essential for the differential diagnosis. The patient should be treated according their clinical manifestation, staging, comorbidity, and immune function.

Published: January 2024

Background: We aimed to analyze levels of knowledge and behavior regarding diabetic foot care and prevention in persons with diabetes according to the International Working Group on the Diabetic Foot (IWGDF) risk stratification system.
Methods: This descriptive study included 83 persons with diabetes at different risk levels for diabetic foot ulceration (DFU) (IWGDF risk 0–3). The previously validated Patient Interpretation of Neuropathy questionnaire was used to analyze their levels of understanding of foot complications. Participants responded using a 5-point Likert scale.
Results: Patients with IWGDF risk 3 knew that good circulation and absence of polyneuropathy in their feet were related to healthy feet relative to the other groups. In addition, they knew that a DFU is not painful relative to the other groups. High-risk patients knew which physical causes could affect the development of a DFU and that foot self-care and medical control could prevent DFU.
Conclusions: Patients with IWGDF risk 3 knew the natural progression of diabetic foot complications and how to prevent them. Clinicians should focus their efforts on educating patients with diabetes who are at lower risk for DFU.
Transfemoral limb loss modestly increases the metabolic cost of optimal control simulations of walking
Authors: Miller Ross H. , Bell Elizabeth M. , Russell Esposito Elizabeth 
Published: January 2024

Background
In transtibial limb loss, computer simulations suggest that the maintenance of muscle strength between pre- and post-limb loss can maintain the pre-limb loss metabolic cost. These results are consistent with comparable costs found experimentally in select cases of high functioning military service members with transtibial limb loss. It is unlikely that similar results would be found with transfemoral limb loss, although the theoretical limits are not known. Here we performed optimal control simulations of walking with and without an above-knee prosthesis to determine if transfemoral limb loss per se increases the metabolic cost of walking.

Methods
OpenSim Moco was used to generate optimal control simulations of walking in 15 virtual “subjects” that minimized the weighted sum of (i) deviations from average able-bodied gait mechanics and (ii) the gross metabolic cost of walking, pre-limb loss in models with two intact biological limbs, and post-limb loss with one of the limbs replaced by a prosthetic knee and foot. No other changes were made to the model. Metabolic cost was compared between pre- and post-limb loss simulations in paired t-tests.

Results
Metabolic cost post-limb loss increased by 0.7–9.3% (p < 0.01) depending on whether cost was scaled by total body mass or biological body mass and on whether the prosthetic knee was passive or non-passive.

Conclusions
Given that the post-limb loss model had numerous features that predisposed it to low metabolic cost, these results suggest transfemoral limb loss per se increases the metabolic cost of walking. However, the large differences above able-bodied peers of ∼20–45% in most gait analysis experiments may be avoidable, even when minimizing deviations from able-bodied gait mechanics.
