The prognosis for France remains dim. Macron’s legacy is in jeopardy and if the crisis endures, he could become a lame duck president for the rest of his tenure

When India is judged on tariffs, two parameters are used – one is the simple average tariffs and the other is trade-weighted tariffs.

Is Tejashwi’s promise even feasible on the ground? How many households are there in Bihar? How many jobs will the administration have to create in order to fulfill this promise? Let’s take a look at the math.

Developing lightweight material structure has produced the growth in sustainable and demanding application in the field of aerospace, automotive, and construction. This study is intended to evaluate stress concentration factor (SCF) and mechanical properties around the hole aperture in fabricated structure alternatively layered with ceramic-reinforced polylactic: lightweight Material 1 (LwM1) and carbon-reinforced polylactic acid: lightweight Material 2 (LwM2), resulting in the development of lightweight material structure. Mechanical behavior of fabricated lightweight material structure was evaluated through open-hole tensile testing (OHTT) method along with base LwM1 and LwM2. To obtain a clearer quantification of central aperture, influenced by internal stress state, SCF was evaluated in this study. The experimental results exposed that LwM1 displayed high tensile strength (45.75 MPa) and the lowest stress concentration while LwM2 possessed the least tensile strength (36.63 MPa) with peak SCF values. Lightweight material structure exhibited tensile strength of 41.25 MPa, and an SCF intermediate between LwM1 and LwM2. Further, to correlate the experimental findings, finite element (FE) simulation was used. The combined analysis reveals that lightweight material structure leverages high tensile efficiency of LwM1 and stiffness of carbon reinforcement, contribution a lightweight and mechanically strong alternative to traditional metallic components in advanced structural application.

Fibrous dysplasia of the temporal bone and petrous apex is an uncommon benign fibro-osseous disorder, particularly in elderly individuals. Involvement of the skull base may present with atypical cranial neuropathies and may mimic inflammatory, vascular, or neoplastic diseases. This report describes a 90-year-old woman with recurrent unilateral facial pain and episodic facial muscle contractions. Initial assessment considered neoplastic pathology and inflammatory vasculopathy. Serial clinical evaluations, laboratory investigations, and neuroimaging established the diagnosis of left petrous apex fibrous dysplasia extending into Meckel's cave and the internal auditory meatus, resulting in mass effect on the trigeminal nerve. Multidisciplinary neurosurgical and neurological consultation advised conservative management due to advanced age, stable symptoms, absence of progressive neurological deficits, and favourable response to pregabalin. This case highlights a rare and diagnostically challenging skull base lesion with overlapping features of trigeminal neuralgia and hemifacial spasm and underscores the importance of avoiding invasive interventions in carefully selected frail elderly patients when symptom control is achievable through conservative measures.
